Description

Scheduling method, network equipment and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a scheduling method, a network device, and a terminal.

Background

Currently, a time domain resource allocation scheme for scheduling an uplink multiple Transmission Time Interval (TTI) based on a New Radio (NR) access to an Unlicensed Spectrum (NR-U) includes: when no Gap (Gap) exists between one or more Physical Uplink Shared Channels (PUSCHs) scheduled by a single Downlink Control Information (DCI), in order to indicate the symbol allocation condition of each slot in multiple slots, the time domain resource allocation table in NR is used, but the S and L (or SLIV) parameters are explained again as follows:

the start symbol S is applied to the first slot of the scheduled plurality of slots, which ends at symbol 13, i.e. fills all the remaining symbols in this slot starting from the S symbol; the number L of the allocated continuous symbols is applied to the last time slot in the plurality of scheduled time slots, and the last time slot starts from the symbol 0, namely, the symbols 0 to (L-1) in the time slot are occupied; and occupying symbols 0-13 in other time slots except the first time slot and the last time slot in the plurality of scheduled time slots, namely occupying all symbols in the time slots.

When Gap exists between one or more PUSCHs scheduled by a single DCI, time domain resource allocation in the NR PUSCH aggregation is used, i.e. S and L are repeatedly applied in each scheduled slot, and the number of scheduled slots can be indicated by a newly added field in the DCI, and a different TB is transmitted in each slot.

However, the existing NR-U multi-TTI scheduling time domain resource allocation method lacks flexibility.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of a scheduling method according to an embodiment of the present invention, and as shown in fig. 1, the embodiment provides a scheduling method for a network device, including the following steps:

step 101, sending downlink control information DCI for scheduling N physical channels, where the N physical channels are mapped to M time slots, and the DCI includes first indication information, where the first indication information is used to indicate a resource allocation set; the set of resource allocations corresponds to at least one resource allocation subset, each resource allocation subset corresponding to at least one of the M time slots; each resource allocation subset is used for determining transmission parameters of physical channels mapped in a corresponding time slot, wherein N is an integer greater than or equal to 1, and M is an integer greater than or equal to 1.

In a specific embodiment of the present invention, the first indication information is used to indicate a resource allocation set, and at least one resource allocation subset may be determined according to the resource allocation set, where the resource allocation subset corresponds to one or more time slots, and the resource allocation subset is used to determine transmission parameters of a physical channel mapped to the corresponding time slot. In the scheduling method according to the embodiment of the present invention, there is at least one resource allocation subset, and the parameter of each resource allocation subset is a transmission parameter for determining all physical channels in the corresponding time slot. That is, the resource allocation subset corresponds to the time slot, not the physical channel, and in the case of multiple physical channels in the time slot, the resource allocation subset is capable of determining the transmission parameters of all the physical channels in the time slot. In the scheduling scheme in the prior art, the configuration is performed on the physical channel unit, or on all the physical channels, and does not include the configuration on all the physical channels in the time slot unit.

For example, assume that 4 physical channels are scheduled and that 4 physical channels are mapped to 3 slots, where a certain slot X includes 2 physical channels. By using the method of the embodiment of the present invention, in the resource allocation set, the resource allocation subset corresponding to the time slot X can be used to determine the transmission parameters of 2 physical channels in the time slot X, and if the resource allocation subset is configured for other time slots, the corresponding resource allocation subset can also determine the transmission parameters of all physical channels in the time slot.

The prior art scheme does not schedule minislots. Even if it can schedule, it can only schedule 4 physical channels separately, i.e. 4 physical channels are scheduled relatively independently, or all physical channels are scheduled as a whole, and it is not possible to schedule multiple physical channels in the same time slot by using one resource allocation subset in units of time slots.

Meanwhile, for the resource allocation set to the transmission parameters, in the method of the embodiment of the present invention, there is a multilayer correspondence relationship between the resource allocation set, the resource allocation subset, and the physical channel transmission parameters configured by the resource allocation subset, and the multilayer correspondence relationship is different from a single-layer mapping relationship between the resource allocation identifier and the physical channel transmission parameters configured by the resource allocation identifier in the prior art.

Therefore, the scheduling method of the embodiment of the present invention can determine the transmission parameters of all the final physical channels only by indicating one resource allocation set, unlike the LTE that needs to indicate a transmission parameter configuration scheme corresponding to each physical channel, thereby saving signaling overhead.

Meanwhile, in terms of the configuration of the resource allocation set, the resource allocation set is scheduled in units of time slots, and the configuration of the resource allocation subset is considered in combination with the number of physical channels in the time slots, so that the resource allocation set can be applied to scheduling at a micro-slot level.

In an embodiment of the present invention, the first indication information is used to indicate a resource allocation set, where the resource allocation set corresponds to at least one resource allocation subset, and each resource allocation subset corresponds to at least one of the M time slots.

And the above mentioned resource allocation subset corresponding to at least one of the M time slots includes the following cases:

(1) the resource allocation set corresponds to M resource allocation subsets, each resource allocation subset corresponding to one of the M time slots.

That is, each time slot corresponds to a subset of the resource allocations.

(2) The resource allocation subset is applied to only a portion of the M time slots.

In this case, in other words, only the partial time slots are configured with resource allocation subsets, each resource allocation subset corresponding to at least one of the partial time slots, while other time slots are scheduled using other means.

The resource allocation subset of the partial time slot configuration can be divided into two forms: one resource allocation subset is configured per slot and one resource allocation subset is multiplexed to a plurality of slots.

In a multiplexing manner, the resource allocation set is configured with one or more resource allocation subsets, and one or more of these resource allocation subsets are multiplexed one or more times (assuming that the number of times is P2) to determine the transmission parameters of the physical channels of the first P2 slots of the M slots.

The network device may select a suitable resource allocation subset according to actual requirements for the terminal to determine the transmission parameters of the physical channels in the time slot.

In the specific embodiment of the present invention, the Physical Channel may be a Physical Uplink Shared Channel (PUSCH) or a Physical Downlink Shared Channel (PDSCH).

Some parts of the specific embodiment of the present invention are described using PUSCH, but it should be understood that the method of the embodiment of the present invention may also be applied to downlink scheduling, and therefore, the illustration based on PUSCH in the embodiment is not to be understood that the method of the present invention is only applicable to uplink scheduling.

Under the condition that the resource allocation set is used for determining the transmission parameters of the physical channels in the multiple time slots, the network equipment can enable the terminal to determine the resource allocation set according to the indication information through one indication information in the DCI, and determine the transmission parameters of all the physical channels mapped in the corresponding time slots according to the configuration corresponding to the resource allocation subset of the resource allocation set, so that the signaling overhead is saved.

Optionally, at least one of the N physical channels is mapped to a minislot. That is, the method of the embodiment of the present invention can be applied to the scheduling of the micro slot level.

A minislot refers to a division of a symbol set available in a slot (i.e., lot) into a plurality of consecutive subsets, each of which can map one physical channel, thereby increasing scheduling flexibility. As shown in fig. 1a, fig. 1a is a schematic diagram of uplink multi-TTI scheduling time domain resource allocation, where reference numeral 11 in the diagram indicates a timeslot boundary, reference numeral 22 indicates a micro timeslot, and both the micro timeslot and the timeslot can be mapped to a physical channel. The mini slot is supported, so that the opportunity of Listen-Before-Talk (list-Before-Talk, abbreviated as LBT) can be increased, the opportunity and flexibility of LBT can be increased by the micro slot, and the success rate of data transmission and the resource utilization rate are improved.

User Equipment (UE) may perform LBT at all or part of slots or mini slots. According to the distribution situation of the mini slots in the allocated time domain resources, the following two situations can be further distinguished:

in case one, only the first one to a plurality of time slots in the scheduled time slots can be split into mini slots;

in case two, all the scheduled slots can be split into mini slots.

Each case will be described in further detail below.

In order to optimize the signaling load, the transmission parameters of each slot or mini slot related in each slot boundary are defined uniformly, namely, the time slot level time domain resource allocation is carried out, and then the specific application of which set of time slot level time domain resource allocation is applied to each scheduled slot is specified.

Optionally, the first indication information is: identification information of the resource allocation set; or, the resource allocation set is index information in a set composed of a plurality of resource allocation sets.

Specifically, each resource Allocation Set may include one or more pre-configured resource Allocation subsets Slot _ Allocation _ Info (it should be understood that the resource Allocation Set includes resource Allocation subsets, which may also be understood as resource Allocation Set corresponding to or configured with resource Allocation subsets), each resource Allocation subset corresponds to at least one timeslot, each resource Allocation subset may include one or more rows in a time domain transmission parameter table (where a row in the table is indicated by a Part _ Allocation _ Index or a Part _ Allocation _ ID), a row in the table is used to determine the transmission parameters of one physical channel, and one or more physical channels determined by each resource Allocation subset correspond to the same timeslot, that is, it is determined according to the resource Allocation subsets that the time domain transmission resources mapped to all physical channels in the corresponding timeslot are located in the same timeslot, and the time domain transmission resources located in the same timeslot are determined by one resource Allocation subset .

A plurality of resource Allocation sets may form a resource Allocation Set Table Allocation _ Set _ Table, and the resource Allocation sets may be represented by indexes of the resource Allocation sets in the resource Allocation Set Table. Meanwhile, a respective unique resource allocation set identifier may also be set for each resource allocation set in the resource allocation set table, and the resource allocation set may be indicated by the resource allocation set identifier.

When the first indication information is the identification information of the resource Allocation Set, the Allocation _ Set is identified by a unique ID, without considering the relative position of the Allocation _ Set in the Allocation _ Set _ Table, so as to semi-statically adjust (add or delete) part of the Allocation _ Set in the Allocation _ Set _ Table. When some Allocation _ Set is added or deleted in the Allocation _ Set _ Table, the ID of other Allocation _ Set is not affected.

In a first implementation, the resource allocation subset is configured based on the new definition table.

First, the transmission parameters of the physical channels scheduled by the network device are determined by a certain row in the newly defined table, and it is assumed that a certain row is indicated by a Part _ Allocation _ Index or a Part _ Allocation _ ID, the Part _ Allocation _ Index is a row Index of the table, and the Part _ Allocation _ ID is a configuration ID (only when configured) of a certain row, and the row corresponds to a transmission parameter set, including one to more of the following parameters:

starting with symbol S, this parameter is optionally included. When the Slot _ Allocation _ Info does not contain the start symbol First _ S of the First physical channel in the Slot boundary, the other physical channels in the Slot derive the symbol position occupied by the First physical channel based on the number of symbols occupied by the other physical channels and the symbol position occupied by the First physical channel, and at this time, it is required that no Gap exists between the adjacent physical channels in the same Slot.

The number of allocated continuous symbols L indicates the number of continuous symbols occupied by the corresponding physical channel, and the parameter optionally includes.

The type of mapping, this parameter optionally included. When not included, the DM-RS mapping Type of the physical channel may be determined based on a predefined rule, for example, Type a is adopted only when the physical channel occupies the first symbol of the slot and the allocated consecutive symbol number > is 4, and Type B is adopted otherwise.

A configuration ID configured only when a certain line is indicated by the Part _ Allocation _ ID, i.e., the Part _ Allocation _ ID is the configuration ID.

The newly defined table may be specified explicitly in the specification or may be configured in advance by the base station for the UE.

Secondly, the base station configures one or more Slot _ Allocation _ Info (which can be understood as a resource Allocation subset) for the UE in advance to form a Slot _ Allocation _ Table, where each Slot _ Allocation _ Info indicates transmission attributes of one or more physical channels within a single Slot boundary. The Slot _ Allocation _ Info or the Slot _ Allocation _ ID may be used to indicate a certain Slot _ Allocation _ Info in the Slot _ Allocation _ Table, the Slot _ Allocation _ Index being a row Index of the Slot _ Allocation _ Table, and the Slot _ Allocation _ ID being a configuration ID of the certain Slot _ Allocation _ Info (only when configured). Some or all of the following parameters are configured for each Slot _ Allocation _ Info:

time domain symbol occupation information of all physical channels in a single time slot boundary;

a starting symbol First _ S of a First physical channel in a time slot; and

the configuration ID.

The following describes each parameter in detail.

The time domain symbol occupation information of one to multiple physical channels in a single time slot boundary optionally includes the following configuration modes:

the first configuration mode is as follows: one to a plurality of Part _ Allocation _ indexes or Part _ Allocation _ IDs are configured, and each Part _ Allocation _ Index or Part _ Allocation _ ID corresponds to a single physical channel (meanwhile, the sequence of the Part _ Allocation _ indexes or Part _ Allocation _ IDs also determines the chronological order between the corresponding physical channels).

One or more physical channels are included in a single time slot, and all the physical channels need to satisfy the following constraint conditions: 1. no overlap exists between symbols occupied by the physical channels; 2, each physical channel is located within one time slot in the time domain, i.e. not beyond the boundary of a single time slot.

Gap may or may not exist between adjacent physical channels. The following restrictions on the Slot _ Allocation _ Info are described below in conjunction with specific parameters:

when the start Symbol S is configured for a certain Part _ Allocation _ Index or Part _ Allocation _ ID, S and L indicated by two adjacent Part _ Allocation _ indexes or Part _ Allocation _ IDs within the same Slot _ Allocation _ Info are required to ensure that there is no collision, i.e. one of the following two cases is satisfied (if the previous Part _ Allocation _ Index1 or Part _ Allocation _ ID1 corresponds to S1 and L1, the next Part _ Allocation _ Index2 or Part _ Allocation _ ID2 corresponds to S2 and L2, the number of symbols within each Slot is symbolnum; for any Part _ Allocation _ Index or Part _ Allocation _ ID, S + L-1< symbolnum, i.e. no Symbol crossing of a single physical channel):

in the first case: when Gap is allowed to exist between adjacent physical channels, the following condition needs to be satisfied:

when S1+ L1! When S2 is satisfied (i.e., S1+ L1 is not equal to S2), it indicates that Gap exists between the two physical channels, and S1+ L1< S2; when S1+ L1 is S2, it indicates that no Gap exists between the two physical channels.

In the second case: when Gap is required to be absent between adjacent physical channels, the following condition needs to be satisfied:

s1+ L1 is S2, i.e., the symbols occupied by two adjacent physical channels are consecutive. I.e. to all physical channels in the corresponding time slot, the time domain transmission resources of different physical channels determined according to the resource allocation subset do not overlap.

When no start symbol S is configured for a certain Part _ Allocation _ Index or Part _ Allocation _ ID, the symbol position occupied by each physical channel is determined depending on the First _ S configured for the current Slot _ Allocation _ Info at this time, and it is required that: the symbols occupied by each physical channel allocated in the same Slot _ Allocation _ Info cannot cross the Slot boundary, that is, it is determined that the time domain transmission resources mapped to all physical channels in the corresponding Slot are located in the same Slot according to the resource Allocation subset, if the physical channel corresponding to the previous Part _ Allocation _ Index1 or Part _ Allocation _ ID1 of two adjacent Part _ Allocation _ Info or Part _ Allocation _ ID in the Slot _ Allocation _ Info ends at Symbol E1, the consecutive number occupied by the physical channel corresponding to the next Part _ Allocation _ Index2 or Part _ Allocation _ ID2 is L2, and the number of symbols in each Slot is Symbol _ Num, then E1+1+ L2<, Symbol _ Num is required.

The second configuration mode: configuring a single Part _ Allocation _ Index or Part _ Allocation _ ID, wherein the starting symbol S is not configured in the line corresponding to the Part _ Allocation _ Index or Part _ Allocation _ ID; a repetition factor C is configured to indicate that there are C physical channels in the time slot, and the transmission attribute of each physical channel is configured according to the row corresponding to the Part _ Allocation _ Index or the Part _ Allocation _ ID. The symbols corresponding to each physical channel determined by combining the parameter First _ S are required not to exceed the boundary of a single time slot, the physical channels are necessarily continuous in the time domain, and Gap does not exist between adjacent physical channels. I.e. the time domain transmission resources determined by different physical channels do not overlap.

The starting symbol First _ S of the First physical channel in the slot.

When the starting symbol S is not configured in the line corresponding to each Part _ Allocation _ Index or Part _ Allocation _ ID, configuring the parameter; if not explicitly configured, a default value of 0 First _ S may be applied

A configuration ID configured only when a certain line is indicated by the Slot _ Allocation _ ID, i.e., the Slot _ Allocation _ ID is the configuration ID.

Thirdly, the base station configures one or more Allocation _ sets for the UE in advance to form an Allocation _ Set _ Table, and configures one or more of the following parameters for each Allocation _ Set:

slot offset K2;

time domain resource allocation information for one to more time slots; and

the configuration ID.

The following describes each parameter in detail.

A slot offset K2 indicating an offset value of the first scheduled slot n _ PUSCH relative to the slot n in which the DCI is located, n _ PUSCH being n + K2; that is, the resource Allocation Set (i.e., Allocation _ Set) corresponding configuration includes an offset parameter, where the offset parameter is used to indicate a slot offset value between a slot where a first physical channel of the N physical channels is located and a slot where the DCI is located. This parameter must be included.

The time domain resource allocation information of one to multiple time slots can be implemented as follows: the configuration of each scheduled time slot is listed and the start effective position in the first time slot and/or the end effective position in the last time slot are indicated, or the configuration and the start effective position of the first scheduled time slot, the configuration of the middle time slot and the configuration and the end effective position of the last time slot are listed.

When the manner of "listing the configuration of each scheduled time slot and indicating the effective starting position in the first time slot and/or the effective ending position in the last time slot" is adopted, the parameter of the resource Allocation Set (i.e. Allocation _ Set) configuration comprises at least one of the following parameters:

a Slot _ Allocation _ Index or Slot _ Allocation _ ID sequence;

start valid position Start _ PUSCH _ Index in the first slot; and

the end effective position in the last slot.

The following describes each parameter in detail.

The Slot _ Allocation _ Index or Slot _ Allocation _ ID sequence, optionally, may adopt some configuration as follows:

one to a plurality of configured Slot _ Allocation _ indexes or Slot _ Allocation _ IDs, where each Slot _ Allocation _ Index or Slot _ Allocation _ ID corresponds to a single scheduled time Slot one by one, the order of the Slot _ Allocation _ indexes or Slot _ Allocation _ IDs determines the chronological order of the time slots, and the maximum number of the Slot _ Allocation _ indexes or Slot _ Allocation _ IDs that can be included in a single Allocation _ Set may be defined by a protocol, for example, limited to 4 or 8.

Or,

a subset of resource allocations is configured, i.e. the set of resource allocations corresponds to a subset of resource allocations. That is, a single Slot _ Allocation _ Index or Slot _ Allocation _ ID is configured for the resource Allocation set; and configuring a repetition factor L1, and using the configured single Slot _ Allocation _ Index or Slot _ Allocation _ ID L1 times to indicate that L1 slots are scheduled, wherein each Slot applies the configuration corresponding to the Slot _ Allocation _ Info (i.e., resource Allocation subset) indicated by the Slot _ Allocation _ Index or Slot _ Allocation _ ID.

Or,

only one resource Allocation subset is configured, i.e., a single Slot _ Allocation _ Index or Slot _ Allocation _ ID is configured for the resource Allocation set. And the above-mentioned repetition factor L1 is indicated by the network by other means.

For each resource allocation subset, only one transmission parameter set may be configured and mapped to all physical channels in the slot, as described above. At this time, the resource allocation subset corresponds to a first transmission parameter group and a first repetition number parameter L which are repeatedly used, or corresponds to a start parameter, a first transmission parameter group and a first repetition number parameter L which are repeatedly used, L physical channels are mapped in a time slot corresponding to the resource allocation subset, and L is an integer greater than or equal to 1. The first repetition number parameter L here is equivalent to the meaning and effect of the repetition factor C in the foregoing second configuration.

That is, the resource allocation subset includes a first transmission parameter group and a first repetition number parameter L, which are repeatedly used, so that the first transmission parameter group can be used L times to obtain the transmission parameters of L physical channels, and at this time, the slot corresponding to the resource allocation subset can be mapped with L physical channels. For example, a single Part _ Allocation _ Index or Part _ Allocation _ ID is configured; and configuring a repetition factor L to indicate that L physical channels are scheduled, wherein each physical channel applies the configuration indicated by the Part _ Allocation _ Index or the Part _ Allocation _ ID.

The start parameter is used to indicate a start symbol of the first one of the L physical channels within the slot, i.e. when the resource allocation subset comprises the start parameter, the start symbol of the first one of the L physical channels within the slot uses the value of the start parameter. A default value of 0 may be applied if the resource allocation subset does not include the start parameter.

In addition, one resource allocation subset may also be configured with L transmission parameter sets, which are mapped to L physical channels, respectively.

That is, the resource allocation subset corresponds to L second transmission parameter groups, or corresponds to a start parameter and L third transmission parameter groups, L physical channels are mapped in a time slot corresponding to the resource allocation subset, and L is an integer greater than or equal to 1;

the L second transmission parameter groups correspond to the L physical channels, or the L third transmission parameter groups correspond to the L physical channels;

each of the second sets of transmission parameters includes a location parameter;

each of the third transmission parameter sets comprises a length parameter;

the location parameter is used for indicating the time domain location of the corresponding physical channel in the time slot.

The starting parameter is used for indicating a starting symbol of a first physical channel in the L physical channels in a time slot;

the length parameter is used for indicating the number of continuous symbols occupied by the corresponding physical channel.

That is, the resource allocation subset includes L transmission parameter sets, and the cases corresponding to L physical channels respectively include the following two cases:

the first one is: the resource allocation subset includes L second transmission parameter sets, each of which includes a location parameter for indicating a time domain location of the corresponding physical channel in the time slot, in which case, among the plurality of physical channels determined according to the second transmission parameter set, adjacent physical channels may be consecutive (i.e., no gap exists) or non-consecutive (i.e., a gap exists).

The second method is as follows: the resource allocation subset includes a start parameter and L third transmission parameter sets, each third transmission parameter set includes a length parameter, the start parameter is used for indicating a start symbol of a first physical channel in the L physical channels in a time slot, and the length parameter is used for indicating the number of consecutive symbols occupied by the corresponding physical channel. In this case, the location parameter does not need to be configured for each transmission parameter set, and may be configured for the first Part _ Allocation _ Index or Part _ Allocation _ ID.

In the plurality of physical channels determined according to the third transmission parameter group, adjacent physical channels are consecutive (i.e. there is no gap), so that when the plurality of physical channels are consecutive in the time domain, by determining the starting point of the first physical channel, for the transmission parameter group corresponding to each physical channel, all the transmission parameters of each physical channel in the resource allocation subset can be determined by the length parameter.

A Start valid position Start _ PUSCH _ Index in the first Slot, which indicates an Index of a first physical channel valid in one to multiple physical channels included in the first Slot _ Allocation _ Index or the Slot _ Allocation _ Info indicated by the Slot _ Allocation _ Index or the Slot _ Allocation _ ID (corresponding to the first Slot); configuration may be displayed, and if not explicitly configured, a default value Start _ PUSCH _ Index may be applied of 0. The position of the physical channel in the first time slot of the M time slots where the start of the physical channel is effective can be determined in the above manner.

A terminal valid position End _ PUSCH _ Index in the last Slot, which indicates an Index of the last physical channel valid in the one to multiple physical channels contained in the last Slot _ Allocation _ Index or the Slot _ Allocation _ Info indicated by the Slot _ Allocation _ Index or the Slot _ Allocation _ ID (corresponding to the last Slot); configuration may be shown, and if not explicitly configured, a default value End _ PUSCH _ Index may be applied as an Index of the last physical channel of one to more physical channels included in the last Slot _ Allocation _ Index or the Slot _ Allocation _ Info indicated by the Slot _ Allocation _ ID. The termination effective position of the physical channel in the last time slot of the M time slots can be determined through the method.

When the manner of "listing the configuration and the start effective position of the first time slot, the configuration of the middle time slot, and the configuration and the end effective position of the last time slot of the schedule" is adopted, the parameter of the resource allocation set configuration includes at least one of the following parameters:

the Slot _ Allocation _ Index or the Slot _ Allocation _ ID corresponding to the configuration of the first Slot;

configuring an intermediate time slot;

the Slot _ Allocation _ Index or the Slot _ Allocation _ ID corresponding to the configuration of the last Slot; and

the configuration ID.

The following are described below.

The Slot _ Allocation _ Index or the Slot _ Allocation _ ID corresponding to the configuration of the First Slot, that is, the First _ Slot _ Allocation _ Index or the First _ Slot _ Allocation _ ID; this parameter must be included.

A Start valid position Start _ PUSCH _ Index in the First Slot indicates an Index of a First valid physical channel of the one to more physical channels included in the Slot _ Allocation _ Info indicated by First _ Slot _ Allocation _ Index or First _ Slot _ Allocation _ ID (corresponding to the First Slot); configuration may be displayed, and if not explicitly configured, a default value Start _ PUSCH _ Index may be applied of 0.

The configuration of the middle Slot corresponds to a Slot _ Allocation _ Index or a Slot _ Allocation _ ID sequence, optionally contains (if not contained, it indicates that there is no middle Slot), and may adopt some configuration manner as follows:

one to a plurality of Slot _ Allocation _ indexes or Slot _ Allocation _ IDs are configured, each Slot _ Allocation _ Index or Slot _ Allocation _ ID corresponds to a single scheduled time Slot, the sequence of the Slot _ Allocation _ indexes or Slot _ Allocation _ IDs determines the chronological order of the time slots, and the maximum number of the Slot _ Allocation _ indexes or Slot _ Allocation _ IDs that can be included in the sequence can be limited by the protocol, for example, to 3 (i.e., 4-1) or 7 (i.e., 8-1).

Or,

configuring a single Slot _ Allocation _ Index or Slot _ Allocation _ ID, and configuring a repetition factor M to indicate that all the middle M scheduling slots apply the configuration corresponding to the Slot _ Allocation _ Info indicated by the Slot _ Allocation _ Index or Slot _ Allocation _ ID.

The Slot _ Allocation _ Index or Slot _ Allocation _ ID corresponding to the configuration of the Last Slot, that is, Last _ Slot _ Allocation _ Index or Last _ Slot _ Allocation _ ID; this parameter may optionally include, if not:

when the configuration of the middle time Slot is contained, using the last Slot _ Allocation _ Index or Slot _ Allocation _ ID in the Slot _ Allocation _ ID sequence or the Slot _ Allocation _ Index corresponding to the middle time Slot;

when the configuration of the intermediate Slot is not included, the First _ Slot _ Allocation _ Index or the First _ Slot _ Allocation _ ID is used.

An End effective position End _ PUSCH _ Index in the Last Slot indicates an Index of the Last physical channel effective in one to multiple physical channels contained in the Slot _ Allocation _ Info indicated by Last _ Slot _ Allocation _ Index or Last _ Slot _ Allocation _ ID (corresponding to the Last Slot); configuration may be shown, and if not explicitly configured, an Index of the Last physical channel of the one to more physical channels included in the Slot _ Allocation _ Info indicated by the default value End _ PUSCH _ Index or the Slot _ Allocation _ ID may be applied.

And a configuration ID configured only when a certain Allocation _ Set is indicated by the Allocation _ Set _ ID, that is, the Allocation _ Set _ ID is the configuration ID.

Finally, during scheduling, the base station indicates one of the Allocation _ Set in the Allocation _ Set _ Table based on the Allocation _ Set _ Index or the Allocation _ Set _ ID by scheduling a time domain resource Allocation field (corresponding to a "time domain resource Allocation" field in NR) in the DCI, that is, the first indication information is transmitted through the time domain resource Allocation field, and if the value of the time domain resource Allocation field is m:

when the Allocation _ Set is indicated based on the Allocation _ Set _ Index, the Allocation _ Set is used as Allocation _ Set _ Table (m + 1); the number of bits of the time domain resource Allocation field may be Set to ceiling (log2(Allocation _ Set _ Num)), where ceiling () is a ceiling operation and Allocation _ Set _ Num is the number of Allocation _ sets contained in Allocation _ Set _ Table. That is, the bit number of the time domain resource allocation domain is an rounded-up value of log2(X), where X is the number of the pre-configured resource allocation set.

When the Allocation _ Set is indicated based on the Allocation _ Set _ ID, the Allocation _ Set with ID m is used; the number of bits of the time domain resource Allocation field may be Set to ceiling (log2(Max _ Allocation _ Set _ ID +1)), where ceiling () is a ceiling operation, Max _ Allocation _ Set _ ID is the maximum value of the ID of Allocation _ Set, and the ID of Allocation _ Set may be numbered from 0. That is, the bit number of the time domain resource allocation domain is an rounded-up value of log2(X), where X is the maximum value of the preconfigured resource allocation set identifier plus one.

Meanwhile, the number of physical channels scheduled by the DCI may be indicated in the following manner:

after the base station determines the Allocation _ Set in the DCI by the time domain resource Allocation field, the number of slots included in the Allocation _ Set and the number of physical channels in the Slot _ Allocation _ Info corresponding to each Slot determine the number of physical channels PUSCH _ Num simultaneously scheduled by the DCI (i.e., PUSCH _ Num is the sum of all PUSCH in the slots in the Allocation _ Set determined by the time domain resource Allocation field), and no other indication information is needed.

In addition, the base station may also use a separate field in the DCI to indicate the number of actually scheduled PUSCHs, PUSCH _ Num, i.e. the DCI further includes second indication information for indicating the value of N.

At this time, the indicated PUSCH _ Num is required to satisfy some condition as follows:

the PUSCH _ Num is equal to the number of PUSCHs in Allocation _ Set determined by the time domain resource Allocation domain;

and when the PUSCH _ Num <, which is the number of PUSCHs in the Allocation _ Set determined by the time domain resource Allocation domain, is less than the number of PUSCHs in the Allocation _ Set, taking the previous PUSCH _ Num Allocation _ Index in the determined Allocation _ Set to respectively determine the transmission attribute of each scheduled PUSCH.

That is, in case the number of transmission parameter sets determined from the transmission resource allocation set is larger than N, the first N transmission parameter sets may be selected as the transmission parameters of the N physical channels.

The above-described approach can be applied to both cases where only the first one to a plurality of slots of the scheduled slots can be split into mini slots and where all slots of the schedule can be split into mini slots.

For uplink multi-TTI scheduling, mini slot transmission is employed in the first or multiple slots, which may increase LBT opportunities. After the UE successfully accesses the channel, it can transmit with relatively large time-domain granularity (e.g., based on a complete slot) to avoid occupying more HARQ processes.

That is, the remaining timeslots except the first timeslot or the first few timeslots can be restricted from physical channel transmission based on timeslot granularity (Partial timeslot granularity can be adopted in the last timeslot), so implementation two is introduced.

In the second implementation manner, the resource allocation subset is configured based on the newly defined table, and is applied to the first or the first several scheduling time slots, including the following two cases:

the first case is: the set of resource allocations corresponds to P1 resource allocation subsets, the P1 being a positive integer less than or equal to M, the P1 resource allocation subsets corresponding to the first P1 of the M slots; in the other time slots except the first P1 time slots, each of the M time slots maps a physical channel.

Specifically, the resource allocation set includes P1 resource allocation subsets, P1 resource allocation subsets correspond to the first P1 time slots of the M time slots, and a certain resource allocation subset corresponds to a time slot with the same index or permutation position. The first P1 time slots of the M time slots respectively determine the transmission parameters of one or more physical channels mapped in each time slot according to the P1 resource allocation subsets included in the resource allocation set. Of the M slots, the other slots except the first P1 slots map one physical channel per slot.

At this time, the terminal may determine the number of scheduled time slots according to the number of resource allocation subsets included in the resource allocation set.

The second case is: the resource allocation set corresponds to 1 resource allocation subset, or 1 resource allocation subset and a second repetition number parameter P2, and is used for determining transmission parameters of physical channels mapped in the first P2 slots of the M slots, where P2 is a positive integer less than or equal to M, and each of the other slots except the first P2 slots of the M slots maps one physical channel.

The above-mentioned P2 may be configured in the resource allocation set directly or may be notified by the network side through other manners, see the following description.

Specifically, in the second case, the resource allocation set includes 1 resource allocation subset, which can be used P2 times, that is, the resource allocation set actually corresponds to P2 identically configured resource allocation subsets, and these P2 resource allocation subsets can correspond one-to-one to the first P2 slots. Of the M slots, the other slots except the first P2 slots map one physical channel per slot.

The resource allocation subset is configured based on the new definition table, and is applied to the first or the first several scheduling time slots, and the specific process is as follows:

first, a newly introduced table with respect to NR is previously configured for the UE. The transmission parameters of the physical channels scheduled by the network device are determined by a certain row in a newly defined table, assuming that a certain row is indicated by a Part _ Allocation _ Index or a Part _ Allocation _ ID, the Part _ Allocation _ Index is a row Index of the table, the Part _ Allocation _ ID is a configuration ID of a certain row (only when configured), and the row indicated by the Part _ Allocation _ Index/Part _ Allocation _ ID includes parameters of a start symbol S (optional), a number of consecutive symbols L allocated, a mapping type (optional), and a configuration ID, and the specific description refers to the corresponding description in implementation mode one.

Then, one or more Slot Allocation Info (which can be understood as a resource Allocation subset) are configured for the UE in advance by the base station to indicate the transmission properties of one or more physical channels within a single Slot boundary. One or more Slot _ Allocation _ Info forms a Slot _ Allocation _ Table. The configuration of each Slot _ Allocation _ Info has been explained in detail previously, and is not described repeatedly here.

And thirdly, referring to the existing operation in NR, the method is specified in advance based on a protocol, or the base station semi-statically configures a time domain resource allocation table for the UE through RRC signaling, and the structure and the configuration method of the table are specified based on the NR protocol, and the table can be multiplexed by Single-TTI scheduling of a physical channel and Multi-TTI scheduling of the physical channel, and can also be independently used by the Multi-TTI scheduling of the physical channel.

The time domain resource allocation table is used to determine the transmission parameters of the physical channels of the other time slots except the first P1 or P2 time slots among the M time slots.

That is to say, in the specific embodiment of the present invention, the DCI includes first indication information for determining, in units of time slots, transmission parameters of physical channels in the first P1 or P2 time slots, and further includes third indication information for determining, in units of physical channels, physical channels in other time slots of the M time slots except for the first P1 or P2 time slots.

Since one physical channel is mapped to each of the M slots except for the first P1 or P2 slots, transmission parameters of a part of the physical channels may be used for other purposes, such as S and L (or SLIV). In a specific embodiment of the present invention, S and L (or SLIV) are used to indicate the channel information parameters (i.e., to re-interpret, not indicate the information specified in the NR, but indicate other channel allocation information, such as indicating the channel information parameters described below). Meanwhile, the offset parameter and the mapping type parameter are also extended in meaning with respect to the specification in NR.

That is, the DCI further includes third indication information indicating a fourth transmission parameter group including: an offset parameter, a channel information parameter, and a mapping type parameter;

the offset parameter is used for indicating a time slot offset value between a first time slot of the M time slots and a time slot in which the DCI is positioned;

the channel information parameter includes at least one of a first slot parameter and a second slot parameter, the first slot parameter indicating: a starting symbol index of a physical channel in a first one of the M slots, or an index of a first physical channel in a first one of the M slots, or a number of physical channels mapped in a first one of the M slots;

the second slot parameter indicates: the number of symbols allocated in the last slot of the M slots, or the number of physical channels mapped in the last slot of the M slots, or an ending symbol index of a physical channel in the last slot of the M slots;

the mapping type parameter indicates: a DM-RS mapping type of the other slots of the M slots except the first P1 or P2 slots.

The details are as follows.

Each row in the above table indicates the following parameters: k2, S and L (or SLIV), mapping type. S and L (or SLIV), and the mapping type are reinterpreted as follows:

s is explained again in some way as follows:

s indicates the first time slot of the scheduling to start transmitting the symbol index;

s indicates the PUSCH index of starting transmission in the first scheduled time slot;

s indicates the number of PUSCHs that need to be transmitted in the first scheduled slot.

L is explained again in some way as follows:

l indicates the number of continuous symbols allocated in the last time slot of the scheduling;

l indicates the number of PUSCHs allocated in the last scheduled time slot;

l indicates the end of transmission symbol index in the last slot of the schedule.

The mapping type is reinterpreted as follows:

indicating the DM-RS mapping type of the remaining scheduled PUSCH slots except for the first P1 or P2 PUSCH slots (see previous description for meaning of P1 or P2).

The base station optionally configures a quantity parameter a for the UE, and adopts a certain mode as follows:

the base station is directly configured through a high-level signaling, or the value of A is directly specified on a protocol, or a default value specified by the protocol is used when the base station is not configured for the UE;

the base station indicates, in the scheduling DCI, local indexes of PUSCH slots transmitted with slot granularity in all scheduled PUSCH slots, so as to indirectly determine a value of a, for example, the base station indicates that transmission is performed with slot granularity from a third scheduled PUSCH slot, and then the UE may infer that a is 2.

This quantity parameter a may be used to indicate P2 described above when the resource allocation set corresponds to only 1 resource allocation subset.

Finally, during scheduling, the base station indicates a certain row in the configured NR time domain resource allocation table by scheduling a time domain resource allocation field (corresponding to a "time domain resource allocation" field in the NR), that is, the third indication information is transmitted by the time domain resource allocation field, that is, assuming that the value of the time domain resource allocation field is m, then the transmission attribute specified by the m +1 th row in the NR time domain resource allocation table after reinterpretation is used, and a plurality of slots or mini slots used for DCI scheduling are used, at this time, all scheduling slots except the first or first P1 or P2 PUSCH slots adopt PUSCH transmission with slot granularity (certain Gap or symbol is left at the beginning and end of the slot as required), and the DM-RS mapping type is indicated based on the correspondence in the m +1 th row. Determination of PUSCH transmission properties within the first or first P1 or P2 PUSCH slots may be done in some way as follows:

the first method is as follows: the base station newly introduces an additional Time domain resource Allocation two-field in the scheduling DCI (for example, a "Time domain resource Allocation 2" field is newly added in the DCI) to indicate a certain Slot _ Allocation _ Info in the configured Slot _ Allocation _ Table or indicate a certain Allocation _ Set in the configured Allocation _ Set _ Table, that is, the first indication information is transmitted through the Time domain resource Allocation two-field.

When a Slot _ Allocation _ Info in the configured Slot _ Allocation _ Table is indicated, a single resource Allocation set corresponds to 1 resource Allocation subset, and if the value of the time domain resource Allocation two-domain is m 2:

when the Slot _ Allocation _ Info is indicated based on the Slot _ Allocation _ Index, the Slot _ Allocation _ Info is used as the Slot _ Allocation _ Table (m2+ 1); the number of bits of the time domain resource Allocation two-field may be set to ceiling (log2(Slot _ Allocation _ Num)), where ceiling () is a ceiling operation and Slot _ Allocation _ Num is the number of Slot _ Allocation _ Info contained in Slot _ Allocation _ Table. That is, the number of the pre-configured resource allocation sets is equal to the number of the pre-configured resource allocation subsets, the number of bits of the time domain resource allocation two domain is an rounded-up value of log2(X), and X is the number of the pre-configured resource allocation sets.

When the Slot _ Allocation _ Info is indicated based on the Slot _ Allocation _ ID, the Slot _ Allocation _ Info of which ID is m2 is used; the number of bits of the time domain resource Allocation two-field may be set to ceiling (log2(Max _ Slot _ Allocation _ ID +1)), where ceiling () is a ceiling operation and Max _ Slot _ Allocation _ ID is the maximum value of the ID of Slot _ Allocation _ Info. That is, the identifier of the pre-configured resource allocation set is completely consistent with the identifier of the pre-configured resource allocation subset, the number of bits of the time domain resource allocation two domain is an upper integer of log2(X), and X is the maximum value of the identifier of the pre-configured resource allocation set plus one.

When one Allocation _ Set in the configured Allocation _ Set _ Table is indicated, a single resource Allocation Set corresponds to at least one resource Allocation subset, and if the value of the time domain resource Allocation two domain is m 2:

when the Allocation _ Set is indicated based on the Allocation _ Set _ Index, the Allocation _ Set is used as Allocation _ Set _ Table (m2+ 1); the number of bits of the time domain resource Allocation two-field may be Set to ceiling (log2(Allocation _ Set _ Num)), where ceiling () is a rounding-up operation and Allocation _ Set _ Num is the number of Allocation _ sets contained in Allocation _ Set _ Table. That is, the number of bits of the time domain resource allocation two domains is an rounded-up value of log2(X), where X is the number of the pre-configured resource allocation set.

When the Allocation _ Set is indicated based on the Allocation _ Set _ ID, the Allocation _ Set with ID m2 is used; the number of bits of the time domain resource Allocation field may be Set to ceiling (log2(Max _ Allocation _ Set _ ID +1)), where ceiling () is a ceiling operation, Max _ Allocation _ Set _ ID is the maximum value of the ID of Allocation _ Set, and the ID of Allocation _ Set may be numbered from 0. That is, the bit number of the time domain resource allocation two domains is an upward integer of log2(X), where X is the maximum value of the pre-configured resource allocation set identifier plus one.

The second method comprises the following steps: the base station still uses the time domain resource Allocation field in the scheduling DCI to simultaneously indicate a certain Slot _ Allocation _ Info in the configured Slot _ Allocation _ Table, or to simultaneously indicate a certain Allocation _ Set in the configured Allocation _ Set _ Table, at this time, the operation of determining the applied Slot _ Allocation _ Info or Allocation _ Set based on the value m of the time domain resource Allocation field is substantially consistent with the foregoing description, and only m2 is replaced with m.

After determining the Slot _ Allocation _ Info applied for the first or first P1 or P2 PUSCH slots, the PUSCH (S) actually in effect in the first Slot are determined based on the reinterpreted S in line m + 1:

when the S indicates the symbol index for starting transmission in the first scheduled Slot, the PUSCH and the remaining PUSCH starting from the symbol in the Slot _ Allocation _ Info of the application are taken (if the first Slot is also the last Slot, the determination of the remaining PUSCH needs to satisfy the limit of L at the same time), and both are considered to be actually effective.

When the S indicates the PUSCH index for starting transmission in the first scheduled Slot, the PUSCH and the remaining PUSCH corresponding to the index in the Slot _ Allocation _ Info of the application are taken (if the first Slot is also the last Slot, the determination of the remaining PUSCH needs to satisfy the limit of L at the same time), and both are considered to be actually effective.

When the S indicates the number of PUSCHs needing to be transmitted in the first scheduled time Slot, the last S PUSCHs in the Slot _ Allocation _ Info of the application are taken (at the moment, the first time Slot is not necessarily the last time Slot, otherwise, the range of the PUSCHs cannot be defined in some cases), and the PUSCHs are considered to be actually effective.

If P1>1 or P2>1, the remaining P1-1 or P2-1 PUSCH slots, except the first Slot, fully apply the transmission attributes in the above-described Slot _ Allocation _ Info when falling within the scheduling range and scheduled with full Slot granularity.

The last slot scheduled needs to satisfy the constraint of reinterpreted L in row m + 1.

And the base station indicates the number of PUSCHs scheduled by the DCI, and may adopt some manner as follows: the base station uses a separate field in the DCI to indicate the number of PUSCH slots actually scheduled, PUSCH _ Slot _ Num.

The base station uses a separate field in the DCI to indicate the number of actually scheduled PUSCHs, PUSCH _ Num; at this time, the UE deduces the scheduled time domain range based on the parameters of the Slot _ Allocation _ Info, P1 or P2, etc. of the application.

The second implementation may be applicable to the first case.

Optionally, the first, second or third transmission parameter group further includes a mapping type parameter, and the mapping type parameter is used to indicate a mapping type of the DM-RS of the corresponding physical channel.

In the above manner, it can be understood that the time domain effective range of the physical channel is optionally indicated by using the reinterpreted S and L, so that the complexity of signaling design is reduced, the signaling overhead is saved, and the scheduling flexibility is improved.

A Demodulation Reference Signal (DM-RS) mapping Type (MappingType) may include two types, i.e., a first Type (i.e., Type a) and a first Type (i.e., Type B), and the limitations of the two types on S and L are shown in table 1. Type a requires that the allocated symbol always starts from the first symbol of a slot, Type B basically has no limitation on the starting position and the number of the allocated symbols, and the time domain resource allocation is flexible.

TABLE 1

Referring to fig. 2, fig. 2 is a second flowchart of a scheduling method according to an embodiment of the present invention, and as shown in fig. 2, the present embodiment provides a scheduling method for a terminal, including the following steps:

step 201, receiving downlink control information DCI for scheduling N physical channels, where the N physical channels are mapped to M time slots, and the DCI includes first indication information, where the first indication information is used to indicate a resource allocation set; the set of resource allocations corresponds to at least one resource allocation subset, each resource allocation subset corresponding to at least one of the M time slots; each resource allocation subset is used for determining time domain transmission resources mapped to a physical channel in a corresponding time slot, where N is an integer greater than or equal to 1, and M is an integer greater than or equal to 1.

In a specific embodiment of the present invention, the first indication information is used to indicate a resource allocation set, and at least one resource allocation subset may be determined according to the resource allocation set, where the resource allocation subset corresponds to one or more time slots, and the resource allocation subset is used to determine transmission parameters of a physical channel mapped to the corresponding time slot.

In the scheduling method according to the embodiment of the present invention, there is a resource allocation subset, and the corresponding configured parameter is a transmission parameter for determining all physical channels in the corresponding time slot. That is, the resource allocation subset corresponds to the time slot, not the physical channel, and in the case of multiple physical channels in the time slot, the resource allocation subset is capable of determining the transmission parameters of all the physical channels in the time slot. However, in the scheduling schemes in the prior art, the configuration is performed in units of physical channels, and does not include configuring all physical channels in a time slot in units of time slots.

For example, assume that 4 physical channels are scheduled and that 4 physical channels are mapped to 3 slots, where a certain slot X includes 2 physical channels. With the method of the embodiment of the present invention, the resource allocation set includes a resource allocation subset, which corresponds to the time slot X described above and is used to determine the transmission resources of 2 physical channels in the time slot X.

Whereas prior art solutions, above all, do not schedule minislots. Even if it can schedule, it can only schedule 4 physical channels respectively, i.e. schedule 4 physical channels relatively independently, and cannot schedule multiple physical channels located in the same time slot by using one resource allocation subset.

That is, each time slot corresponds to a subset of the resource allocations.

(2) The resource allocation subsets correspond to less than M number of time slots, each resource allocation subset corresponding to a time slot. That is, only a part of the time slots are allocated with the resource allocation subset, and other time slots are scheduled by other methods.

In a multiplexing manner, the resource allocation set is configured with one or more resource allocation subsets, and one or more of these resource allocation subsets are repeated one or more times to form a final resource allocation set, so that the resource allocation subsets determined by the final resource allocation set may correspond to M time slots.

The network equipment can determine the transmission parameters of the physical channels in the time slots by setting the resource allocation subsets according to actual requirements, and can flexibly adjust the number of the configured physical channels and the transmission parameters of the physical channels. The physical channel may be a PUSCH or a PDSCH.

Under the condition that the resource allocation set is used for determining the transmission parameters of the physical channels in the multiple time slots, the network equipment can enable the terminal to determine the resource allocation set according to the indication information through one indication information in the DCI, and determine the transmission parameters of the physical channels in the multiple time slots according to the configuration corresponding to the resource allocation subset of the resource allocation set, so that the signaling overhead is saved.

Step 202, determining the transmission parameters of the physical channels mapped in the corresponding time slots according to the at least one resource allocation subset.

After receiving the resource allocation set, the terminal may determine the transmission parameters of the physical channels mapped in the corresponding time slots according to one or more resource allocation subsets in the resource allocation set.

The method of the embodiment of the invention can be applied to part or all of the time slots mapped with the physical channels. When the method is applied to a part of time slots in the time slots to which the physical channels are mapped, the transmission resources of the physical channels in other time slots may be determined by using the method in the prior art, or may be determined by applying the transmission parameter set after redefining according to the embodiment of the present invention.

The scheduling method of the embodiment of the invention receives downlink control information DCI used for scheduling N physical channels, wherein the N physical channels are mapped to M time slots, the DCI comprises first indication information, and the first indication information is used for indicating a resource allocation set; the set of resource allocations corresponds to at least one resource allocation subset, each resource allocation subset corresponding to at least one of the M time slots; each resource allocation subset is used for determining time domain transmission resources mapped to a physical channel in a corresponding time slot, wherein N is an integer greater than or equal to 1, and M is an integer greater than or equal to 1; and determining the transmission parameters of the physical channels mapped in the corresponding time slots according to the at least one resource allocation subset. In this way, the terminal may determine the transmission parameters of one or more physical channels in the time slot according to the resource allocation subset, and the network device may flexibly adjust the number of allocated physical channels and the transmission parameters of the physical channels through the resource allocation subset.

Optionally, at least one of the N physical channels is mapped to a mini slot.

That is, the method of the embodiment of the present invention can be applied to the scheduling of the micro slot level

A minislot (slot) is to divide an available symbol set in a slot into a plurality of consecutive subsets, and each subset may map one physical channel, which increases scheduling flexibility. The mini slot is supported, so that the opportunity of Listen-Before-Talk (list-Before-Talk, abbreviated as LBT) can be increased, the opportunity and flexibility of LBT can be increased by the micro slot, and the success rate of data transmission and the resource utilization rate are improved.

After the base station determines the Allocation _ Set in the DCI by the time domain resource Allocation field, the number of PUSCH slots included in the Allocation _ Set and the number of PUSCHs validated in the Slot _ Allocation _ Info corresponding to each Slot determine the number of PUSCH _ Num simultaneously scheduled by the DCI (i.e. PUSCH _ Num is the sum of all PUSCH validated in each Slot in the Allocation _ Set determined by the time domain resource Allocation field), and no other indication information needs to be used.

The base station may also use a separate field in the DCI to indicate the number of actually scheduled PUSCHs PUSCH _ Num, i.e. the DCI further includes second indication information for indicating the value of N.

PUSCH _ Num requires that certain conditions are met:

and when the PUSCH _ Num <, which is the number of PUSCHs in the Allocation _ Set determined by the time domain resource Allocation domain, is less than the number of PUSCHs in the Allocation _ Set, taking the previous PUSCH _ Num Allocation _ Index in the determined Allocation _ Set to respectively determine the transmission attribute of each scheduled physical channel.

Optionally, the first indication information is transmitted through a time domain resource allocation field, or transmitted through a time domain resource allocation secondary field added in DCI.

During scheduling, the base station indicates one of Allocation _ Set in Allocation _ Set _ Table configured in (13) based on Allocation _ Set _ Index or Allocation _ Set _ ID by scheduling a Time domain resource Allocation field (corresponding to a "Time domain resource Allocation" field in NR) in DCI, that is, the first indication information is transmitted through the Time domain resource Allocation field, and if the value of the Time domain resource Allocation field is m:

When the Allocation _ Set is indicated based on the Allocation _ Set _ ID, the Allocation _ Set with ID m is used; the number of bits of the time domain resource Allocation field may be Set to ceiling (log2(Max _ Allocation _ Set _ ID +1)), where ceiling () is a ceiling operation and Max _ Allocation _ Set _ ID is the maximum value of the ID of Allocation _ Set. That is, the bit number of the time domain resource allocation domain is an rounded-up value of log2(X), where X is the maximum value of the preconfigured resource allocation set identifier plus one.

Specifically, each resource Allocation Set Allocation _ Set may include one or more pre-configured resource Allocation subsets Slot _ Allocation _ Info, each resource Allocation subset corresponds to at least one timeslot, each resource Allocation subset may include one or more rows in a time domain transmission parameter table (the rows in the table are indicated by Part _ Allocation _ Index or Part _ Allocation _ ID), a row in the table is used to determine transmission parameters of one physical channel, and one or more physical channels determined by each resource Allocation subset correspond to the same timeslot, that is, it is determined according to the resource Allocation subsets that time domain transmission resources mapped to all physical channels in the corresponding timeslot are located in the same timeslot.

A plurality of resource Allocation sets may form a resource Allocation Set Table Allocation _ Set _ Table, and the resource Allocation sets may be represented by indexes of the resource Allocation sets in the resource Allocation Set Table. Meanwhile, a respective unique resource allocation set identifier may also be set for each resource allocation set in the resource allocation set table, and the resource allocation set may be represented by the resource allocation set identifier.

Optionally, the resource allocation set corresponding configuration includes an offset parameter, where the offset parameter is used to indicate a slot offset value between a slot in which a first physical channel of the N physical channels is located and a slot in which the DCI is located. Reference may be specifically made to the related description of the first implementation manner in the embodiment shown in fig. 1, which is not described herein again.

Optionally, the resource allocation subset corresponds to a first transmission parameter group and a first repetition number parameter L that are repeatedly used, or corresponds to a starting parameter, the first transmission parameter group and the first repetition number parameter L that are repeatedly used, L physical channels are mapped in a time slot corresponding to the resource allocation subset, and L is an integer greater than or equal to 1.

That is, the resource allocation subset includes a first transmission parameter group and a first repetition number parameter L, which are repeatedly used, so that the first transmission parameter value can be used L times to obtain the transmission parameters of L physical channels, and at this time, the slot corresponding to the resource allocation subset may be mapped with L physical channels. For example, a single Part _ Allocation _ Index or Part _ Allocation _ ID is configured; and configuring a repetition factor L to indicate that L PUSCHs are scheduled, wherein each PUSCH applies the configuration indicated by the Part _ Allocation _ Index or the Part _ Allocation _ ID.

That is, the resource allocation subset corresponds to L second sets of transmission parameters, or to a starting parameter and L third sets of transmission parameters; l physical channels are mapped in a time slot corresponding to the resource allocation subset, wherein L is an integer greater than or equal to 1;

each of the third transmission parameter sets comprises a length parameter;

Specifically, the resource allocation subset includes L transmission parameter sets, which are respectively mapped to L physical channels, including the following two cases.

The second method is as follows: the resource allocation subset includes a start parameter and L third transmission parameter sets, each third transmission parameter set includes a length parameter, the start parameter is used for indicating a start symbol of a first physical channel in the L physical channels in a time slot, and the length parameter is used for indicating the number of consecutive symbols occupied by the corresponding physical channel. In this case, the location parameter does not need to be configured for each transmission parameter set, and may be configured for the first Part _ Allocation _ Index or Part _ Allocation _ ID. In the plurality of physical channels determined according to the third transmission parameter group, adjacent physical channels are consecutive (i.e. there is no gap), so that when the plurality of physical channels are consecutive in the time domain, by determining the starting point of the first physical channel, for the transmission parameter group corresponding to each physical channel, all the transmission parameters of each physical channel in the resource allocation subset can be determined by the length parameter.

Optionally, the resource allocation set is further configured with: a starting effective position of a physical channel in a first time slot of the M time slots; or, the termination effective position of the physical channel in the last time slot of the M time slots.

That is to say, the time domain transmission resources of each physical channel determined according to the resource allocation subset are all located in the same time slot, or no gap exists between the time domain transmission resources of adjacent physical channels, that is, the next symbol of the end symbol of the time domain transmission resource of the previous physical channel is the first symbol of the time domain transmission resource of the next physical channel, or a gap exists between the time domain transmission resources of adjacent physical channels, that is, a gap exists between the end symbol of the time domain transmission resource of the previous physical channel and the first symbol of the time domain transmission resource of the next physical channel.

Optionally, referring to implementation two, the resource allocation subset is configured based on the newly defined table, and is applied to the first or the first several scheduling slots, including the following two cases:

Specifically, the resource allocation set includes P1 resource allocation subsets, P1 resource allocation subsets correspond to the first P1 time slots of the M time slots, and one resource allocation subset corresponds to one time slot. The first P1 slots of the M slots are determined according to P1 resource allocation subsets included in the resource allocation set. Of the M slots, the other slots except the first P1 slots map one physical channel per slot.

The second case is: the resource allocation set corresponds to 1 resource allocation subset, or 1 resource allocation subset and a second repetition number parameter P2, and is used for determining transmission parameters of physical channels of first P2 time slots of the M time slots, where P2 is a positive integer less than or equal to M, and each of the other time slots of the M time slots except the first P2 time slots is mapped with one physical channel.

The above-mentioned P2 may be configured in the resource allocation set directly or may be notified by the network side through other manners.

Specifically, the resource allocation set includes 1 resource allocation subset, which may be used P2 times, that is, the resource allocation set actually includes P2 resource allocation subsets, and the P2 resource allocation subsets may correspond to P2 slots. Of the M slots, the other slots except the first P2 slots map one physical channel per slot.

Optionally, the DCI further includes third indication information, where the third indication information is used to indicate a fourth transmission parameter group, where the fourth transmission parameter group includes: an offset parameter, a channel information parameter, and a mapping type parameter;

the mapping type parameter indicates: and mapping types of the demodulation reference signals DM-RS of the other time slots.

Optionally, the first indication information and the third indication information are transmitted through a time domain resource allocation second domain and a time domain resource allocation domain, respectively.

Specifically, the base station indicates a certain row in the configured NR Time domain resource allocation table by scheduling a Time domain resource allocation field (corresponding to a "Time domain resource allocation" field in the NR) in the DCI, that is, the third indication information is transmitted through the Time domain resource allocation field; the base station newly introduces an additional Time domain resource Allocation two-field in the scheduling DCI (for example, a "Time domain resource assignment 2" field is newly added in the DCI) to indicate a Slot _ Allocation _ Info in a configured Slot _ Allocation _ Table, that is, the first indication information is transmitted through the Time domain resource Allocation two-field.

Referring to fig. 3, fig. 3 is a third flowchart of a scheduling method according to an embodiment of the present invention, and as shown in fig. 3, the embodiment provides a scheduling method for a network device, including the following steps:

step 301, sending downlink control information DCI for scheduling N physical channels, where the N physical channels are mapped to N time slots, and the DCI includes fourth indication information, and the fourth indication information is used to indicate a fifth transmission parameter group;

Specifically, the present embodiment supports multiple starting transmission points, where the S and L (or SLIV) parameters are reinterpreted to support multi-slot scheduling.

When the position of the start transmission point is independent of the start symbol or the end symbol of the PUSCH in a single slot, the following scheme may be considered.

And in the third implementation mode, the S is explained again as the number of allocated symbols in the first time slot and the last time slot, and the L is the number of scheduled continuous time slots. The process is as follows:

first, referring to the existing operation in NR, a time domain resource allocation table is predefined based on a protocol, or a base station semi-statically configures a time domain resource allocation table for a UE through RRC signaling, where the structure and configuration method of the table are defined based on the NR protocol, and in the uplink scheduling, for example, the table may be multiplexed by uplink Single-TTI (Single-TTI) scheduling and uplink Multi-TTI (Multi-TTI) scheduling, or may be used by uplink Multi-TTI scheduling alone. Each row in the table indicates the following parameters: k2, S and L (or SLIV), mapping type. S and L (or SLIV), and the mapping type are reinterpreted as follows.

Wherein S is reinterpreted as follows:

s indicates the number of symbols allocated in the first time slot and the last time slot of the scheduling;

occupying the last S symbols in the first slot, including the last symbol in the slot (certain Gap or symbol may be further vacated at the end of the slot as needed, and the vacated Gap or symbol may or may not be included in S);

occupying the first S symbols in the last slot, including the first symbol in the slot (certain Gap or symbol may be further vacated in the head of the slot as needed, and the vacated Gap or symbol may or may not be included in S);

the middle PUSCH slot occupies all symbols in this slot (certain Gap or symbol may be further vacated at the head or tail of the slot as needed).

L is reinterpreted as follows:

l indicates the number of scheduled consecutive PUSCH slots.

The mapping type is reinterpreted as follows:

indicating the DM-RS mapping types of the rest scheduling PUSCH time slots except the first time slot;

the first time slot can be fixed to adopt Type B, or adopt Type A when occupying the first symbol in the time slot (before considering the vacated symbol or after considering the vacated symbol), otherwise adopt Type B;

secondly, during scheduling, the base station indicates a certain row in the configured NR time domain resource allocation table by scheduling a time domain resource allocation field (corresponding to a "time domain resource allocation" field in NR) in the DCI, that is, assuming that the value of the time domain resource allocation field is m, determines the time domain allocation condition of the PUSCH scheduled by the DCI by using the reinterpretated transmission attribute specified in the m +1 th row in the NR time domain resource allocation table.

In the fourth implementation mode, S is reinterpreted as the starting position in the first time slot, and L is the number of allocated symbols in the last time slot. This is basically consistent with the scheme in the prior art for supporting mini slots, where each slot or mini slot corresponds to a single PUSCH, and the main difference is that:

s is reinterpreted as the starting position in the first time slot.

Assuming that B starting transmission points are defined in a time slot, wherein the nth starting transmission point is located at the beginning of the Start _ symbol (n) symbols, then:

s may take 0 … (B-1), and when S is indicated in DCI, PUSCH in the first slot of this DCI schedule is mapped and transmitted starting with the first Start _ symbol (S) symbols. I.e. each starting transmission point corresponds to the starting instant of one symbol in the first slot.

The above B and Start _ symbol (B) sequences may be explicitly specified in the specification, or may be configured for the UE by the base station in advance.
