Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature.

The term "and/or" herein is merely an association relation describing the association object, and means that three kinds of relations may exist, for example, a and/or B may mean that a exists alone, a and B exist together, and B exists alone. Furthermore, "at least one" means one or more, and "a plurality" means two or more.
In an industrial field network scenario, under the coverage of a base station, there are both direct-connected UEs and some remote UEs, which are directly connected to the head node UE.
As shown in fig. 1, a small network formed by member UEs (such as UE1, UE2 and UE 3) and a head node UE may be referred to as a micro network, in which only the head node is connected to a base station, and other UEs only need to establish connection with the head node UE, so that communication between the UE and another UE or between the UE and the base station can be achieved. The technology can reduce the burden of a cellular network, reduce the battery power consumption of user equipment, well meet the requirements of high data rate service and proximity service, also support direct communication between devices in a network coverage-free scene, and can meet the requirements of low-delay and high-reliability communication in an industrial field network.
That is, similar to the topology in which a plurality of UEs are connected under one base station in the third generation partnership project (third generation partnership project,3 GPP), communication between a head node and a member UE includes the head node transmitting a control channel, the head node transmitting a control channel and a data channel, the member UE transmitting a control channel and a data channel, and the member UE transmitting a feedback channel.
SL communications in 3GPP include device-to-device (D2D), long-term evolution internet of vehicles (long term evolution vehicle-to-everything, LTE V2X) and new air-interface internet of vehicles (new radio vehicle-to-everything, NR V2X). As shown in fig. 2, in D2D, the control channel is in a different time slot (slot) from the data channel, the control channel is in the first few time slots of the communication scheduling period, and the data channel is in the last few time slots of the scheduling period, and corresponds to respective subframe regions (i.e., control subframe region, data subframe region).
The communication delay of the control channel and the data channel distributed in different time slots is large, and the communication delay is not suitable for the scene that the field network has low delay and high reliability requirements, and for LTE V2X, as shown in figure 3, the control channel and the data channel are further placed in one time slot and are in one-to-one correspondence with each other, and the control channel and the data channel are frequency-divided.
I.e., divided into a plurality of sub-bands in the frequency domain over one slot, one sub-band is composed of a Data channel (e.g., data) and a control channel (e.g., synchronization and acquisition (synchronization and acquisition, SA)), and the distribution structure of the control channel and the Data channel is the same in each sub-band.
Compared with the D2D, the channel structure can reduce the transmission delay of data, further, as shown in fig. 4, the time delay of data receiving and transmitting is considered in NR V2X, the resource of the control channel is shortened to 3 symbols, namely, the control channel does not occupy all symbols of the whole time slot, but selects partial symbols for occupation.
However, the resources of the control channel and the data channel are coupled and bound to the sub-bands, and on the direct transmission link of each UE in the field network, the conventional channel structure cannot directly realize separate control transmission, and in addition, the design of the conventional SL control channel is greatly different from that of the Uu control channel, which is not beneficial to one module (module) in 6G to realize the unification of Uu and SL.
To sum up, how to flexibly configure channel resources for different physical channels, avoiding the resource configuration of useless channels to reduce transmission delay. Becomes a technical problem to be solved.
Based on this, in order to solve the above technical problems, the embodiments of the present disclosure provide a communication method, which is applied to a data interaction scenario between UEs in a D2D communication system. The control channel, the data channel and the feedback channel can be selectively applied in the transmission process by flexibly configuring channel resources for at least one channel of the control channel, the data channel and the feedback channel, and the control channel, the data channel and the feedback channel are combined according to the needs, so that the resource configuration of useless channels is avoided to reduce the transmission delay, the low-delay high-reliability communication data transmission requirements between devices are met, and the data direct transmission requirements between UE in an industrial field network are better matched.
The network architecture of the mobile communication network (including but not limited to 2g,3g,4g,5 g) and future mobile communication networks (such as evolution of fifth generation mobile communication technology (5th generation mobile communication technology Advanced,5G-a), sixth generation mobile communication technology (6th generation mobile communication technology,6G)) in embodiments of the present disclosure may include at least a first communication node and a second communication node, it should be appreciated that in this example the first communication node may be a terminal-side device (including but not limited to a terminal for example), the second communication node may be a network side device (e.g., including but not limited to a base station) of course, the first communication node may also be a network side device in the downlink, the second communication node may also be a terminal side device in the two communication nodes are device-to-device communication, the first communication node and the second communication node may be referred to as a first node and a second node, respectively.
Or in SL communication, the first node may be a member node (e.g., a member UE) in the uplink, the second node may be a head node, and the first node may be a head node and the second node may be a member node in the downlink.

Similarly, the head node 504 may also send resource configuration signaling to the member node 502 and/or the member node 503 in turn.
In some embodiments, the head node 504 may send the same resource configuration signaling to different member nodes (e.g., member node 501, member node 502, and member node 503) to uniformly manage all the member nodes. Or the head node 504 may send different resource configuration signaling to different member nodes (e.g., member node 501, member node 502, and member node 503) to provide targeted management of each member node.
In other embodiments, all member nodes (e.g., member node 501, member node 502, and member node 503) and head node 504 may be preconfigured (e.g., factory set) with resource configuration signaling, so that part of the physical channels between the member nodes and the head node, and between the member nodes, are selectively configured as needed.
It should be noted that, in the embodiment of the present disclosure, all the member nodes (such as the member node 501, the member node 502, and the member node 503) and the head node 504 are the same type of terminal. Or all member nodes (e.g., member node 501, member node 502, and member node 503) and head node 504 are different types of terminals. Or some member nodes and the head node 504 in all member nodes are terminals of the same type, and the rest member nodes and the head node 504 are terminals of different types.

Wherein the physical channel may include at least one of a control channel, a data channel, and a feedback channel.
In the embodiment of the present disclosure, the resource configuration signaling is used to indicate candidate channel resources referred to when channel resource configuration is performed on any one of a control channel, a data channel, and a feedback channel.
It should be noted that the channel resources may include time domain resources and frequency domain resources, where the time domain resources are in a unit granularity of one symbol in a slot, and the frequency domain resources are in a unit granularity of one physical resource block (physical resource block, PRB) in the communication frequency domain bandwidth.

As a possible implementation manner, the member node may map the data to be transmitted onto the channel resource corresponding to the physical channel determined by the resource configuration signaling, and further perform data transmission by using the channel resource corresponding to the physical channel.
The member node may send data on a channel resource corresponding to the physical channel, or may receive data on a channel resource corresponding to the physical channel.
That is, by flexibly configuring channel resources for at least one of the control channel, the data channel and the feedback channel, the control channel, the data channel and the feedback channel can be selectively applied in the transmission process, and the control channel, the data channel and the feedback channel can be combined as required, so that the resource configuration of useless channels is avoided to reduce transmission delay, the requirements of low-delay and high-reliability communication data transmission between devices are met, and the data direct transmission requirements between UEs in the industrial field network are better matched.

(b) The time domain resources of the multiple feedback channels are the same;
(c) Frequency division between frequency domain resources of different feedback channels.
In the embodiment of the disclosure, when the physical channel includes both the control channel and the feedback channel, and the time domain resource of the feedback channel is the same as the time domain resource of the control channel, the feedback channel and the control channel share the same candidate frequency domain resource range, and frequency division is performed between the frequency domain resource of the feedback channel and the frequency domain resource of the control channel.
The channel resources (i.e., frequency domain resources and time domain resources) of the control channel, the data channel, and the feedback channel described above are described below in connection with specific examples.
In some embodiments, only control channels and data channels are taken as examples in one slot.
That is, in the field network, the control channel and the data channel are still located in the same slot in consideration of communication delay, but the resources of the control channel and the resources of the data channel are independently configured.
As shown in fig. 7 and 8, the resource occupation of the control channel in the time domain and the frequency domain in different slot structures are shown, respectively. Wherein fig. 7 shows that a control channel, such as a physical side chain control channel (PSCCH), occupies all frequency domain resource blocks (i.e., PRBs) of a communication available resource (i.e., a communication frequency domain bandwidth), and fig. 8 shows that the control channel occupies a portion of the frequency domain resource of the communication available resource. And, as shown in fig. 7 and 8, the first symbol in the slot is an automatic gain control (automatic gain control symbol, AGC) symbol, the last symbol is a gap symbol, and control channel resources (i.e., a channel resource range in which candidates corresponding to a control channel can be occupied) and data (data) channel resources (i.e., a channel resource range in which candidates corresponding to a data channel can be occupied) are divided between the AGC symbol and the gap symbol.
It should be noted that, the resources of the control channel (i.e., the resources occupied by the control channel in the control channel resources) are determined according to the configuration or the pre-predefined rule, and similarly, the resources of the data channel are determined according to the configuration or the pre-predefined rule.
In the time domain, N continuous symbols behind the AGC symbol are time domain resources of a control channel, one control channel occupies N continuous symbols in a time slot, and all symbols between the AGC symbol and the gap symbol are time domain resources of a data channel.
On the frequency domain, on the symbol of the control channel in the time slot, the frequency domain resource size and position of each control channel are fixed, the frequency division is carried out among different control channels, and one control channel occupies continuous or discrete K PRBs in the frequency domain;
Or on the symbol of the control channel in the time slot, the symbol comprises control channels with N types of frequency division, the frequency domain resource size and the position of each type of control channel are fixed, the frequency division is carried out among different control channels, and one control channel in the i type of control channel occupies continuous or discrete K i (i=1, 2,) PRB; each class of control channels may be used for different purposes, configured or pre-configured using different frequency domain sizes, using different signaling.
In addition, on the symbols of the data channel in the time slot, all the remaining resources except the resources occupied by the control channel are available resources of the data channel.
Illustratively, one slot includes 14 time domain symbols. The control channel occupies 2 continuous symbols after the first symbol in the time slot, the SL communication bandwidth is 10M (including 50 PRBs), at this time, the frequency domain of the control channel occupies all PRBs of the communication bandwidth, the time domain symbol position of the data channel is from the 4 th symbol in the time slot to the last second symbol in the time slot, and the frequency domain position of the data channel is 50 PRBs of the whole communication bandwidth.
Further, each control channel occupies 10 PRBs in the frequency domain, so there are 5 candidate control channel resource locations on one slot, and the resources of the data channel of each UE transmitting data occupy part or all of the frequency domain in all available data channels.
That is, the UE occupies all available time domain symbols of the data channel when transmitting data.
In other embodiments, control channels, data channels and feedback channels are included in a single time slot.
That is, when a feedback channel needs to be considered in the field network, another channel structure including feedback resources may be considered.
In combination with the above-mentioned slot structure shown in fig. 8, as shown in fig. 9, another slot structure is shown, which includes resource occupation situations of feedback channels in time domain and frequency domain, where control resources correspond to J PSCCHs (i.e., PSCCH-1, PSCCH-J), and feedback resources correspond to K physical side link feedback channels (PHYSICAL SIDELINK feedback channels, PSFCH) (i.e., PSFCH-1, PSFCH-K). Wherein, the feedback resource (i.e. the channel resource occupied by the feedback channel) and the control resource (i.e. the channel resource occupied by the control channel) are frequency-divided, and different feedback channels in the feedback resource are frequency-divided.
The resource sizes of the feedback channels are identical, and the resource sizes and the positions of the feedback channels are determined according to configuration or pre-configuration signaling or predefined rules.
And the time domain symbol position of the feedback resource in the same time slot is the same as the time domain symbol position of the control channel;
Illustratively, a total of 14 symbols are included in a slot, and the communication bandwidth is 20M (including 100 PRBs). The second symbol to the third symbol in the time slot, the 1 st to 50 th PRB in the frequency domain is the control channel resource in the time slot, and comprises 10 control channels, each control channel occupies 5 PRBs in the frequency domain, and the time domain occupies 2 continuous symbols.
The 51 st to 100 th PRB in the frequency domain is the feedback channel resource in the time slot and comprises 50 feedback resources, one feedback resource occupies 1 PRB in the frequency domain and 2 symbols in the time domain.
In addition, the feedback resources are time slot-cycled, with a system frame number (SYSTEM FRAME number, SFN) of 0 to once every N time slots on the available time slots in the frame SFN1023 in each frame period, where N is the time slot period of the feedback resources (and the control resources can be considered to be present for each time slot).
Illustratively, the time domain resource period of the feedback channel is 4, meaning that 1 slot of every 4 slots contains feedback resources.
In the embodiment of the disclosure, the base station may configure the control channel resources, the feedback channel resources (i.e., the channel resource range that the candidate corresponding to the feedback channel may be occupied) and the data channel resources for the UE.
It should be noted that, the communication bandwidth is not limited to only configuring one control resource, or one feedback resource,
Illustratively, a first control resource (for resource scheduling), a second control resource (for dormant, active indication), a first feedback resource (for hybrid automatic repeat request (hybrid automatic repeat request, HARQ) feedback of data or control), a second feedback resource (for scheduling request transmission), a third feedback resource (for access request), and so on are configured over the communication bandwidth. Resources of different regions may be configured or indicated within the communication bandwidth using a bitmap (bit map) manner or a higher layer signaling indication (starting prb+prb number) manner.
Alternatively, in combination with the above-mentioned slot structure shown in fig. 9, as shown in fig. 10, another slot structure is shown, where feedback channel resources of the feedback channel are located within control channel resources, that is, the control resources (that is, control channel resources) are divided into a feedback area and a control area, where the feedback area includes the feedback channel, and the control area includes the control channel.
In this case, a total control resource position is configured in the frequency domain, and control channel resources and feedback channel resources are further configured in the control resource, and frequency division is performed between control channels, between feedback channels, and between control channels and feedback channels.
Illustratively, the total of 14 symbols in a slot has a communication bandwidth of 20M (including 100 PRBs). The second symbol to the third symbol in the time slot, the 10 th to the 90 th PRB in the frequency domain are control resources in the time slot, further, the first 50 PRBs in the control resources are configured to be control areas, 10 control channels are included, each control channel occupies 5 PRBs in the frequency domain, and the time domain occupies 2 continuous symbols.
The remaining 30 PRBs in the control region are feedback regions in the control resource, and include 30 feedback resources, where one feedback resource frequency domain occupies 1 PRB and the time domain occupies 2 symbols.
Likewise, the feedback channel resources in the control resources may also be configured based on slot cycle.
Illustratively, the time domain resource period of the feedback channel is 4, meaning that 1 slot of every 4 slots contains feedback resources.
In the embodiment of the disclosure, the base station may configure the control channel resource, the feedback channel resource and the data channel resource for the UE.
It should be noted that, in the control resource, it is not limited to configuring only one control area, or one feedback area,
Illustratively, a first control region (for resource scheduling), a second control region (for sleep activation indication), a first feedback region (for HARQ feedback for data or control), a second feedback region (for scheduling request transmission), a third feedback region (for access request), and so on are configured in the control resources. The resources of the different regions may be configured or indicated within the control resources using bit map or higher layer signaling indication (starting prb+prb number).
In addition, in connection with the above-described slot structure shown in fig. 7, as shown in fig. 11, another slot structure in which feedback channels and control channels are time-divided is shown. Wherein, the total P of the 2 nd to P+1 last symbols in the time slot is PSFCH symbols, one PSFCH channel continuously occupies P symbols in the time slot, one feedback channel continuously or discretely occupies Q PRBs in the frequency domain, and the frequency domain resource position of each feedback channel is determined according to configuration or pre-configuration signaling or pre-defined rules.
The first symbol in front of the feedback resource is an AGC symbol, and the AGC symbol is preceded by a gap symbol for transmit-receive conversion.
That is, the slot structure of fig. 11 does not require PSFCH channels and PSCCHs to be identical in the time domain, but there is some more symbol overhead in the time domain, compared to the slot structures of fig. 9 and 10 described above.
Similarly, the configuration of the feedback resources may be periodic with time slots, where the time slot structure is as shown in fig. 11 when PSFCH resources exist in the time slot, and the channel structure is as shown in fig. 7 or fig. 8 in the above embodiment when PSFCH resources do not exist in the time slot.
It should be noted that, the determination of the feedback resources (i.e., the resources occupied by the feedback channel in the feedback channel resources) of the UE may be associated with the control resources.
In some embodiments, there is an association between time-frequency domain resources of a control channel in a current time slot and time-frequency domain resources of feedback channels in a first type feedback channel in N types in a future time slot after a determined time slot interval, one control channel corresponds to 1 or more feedback channels, and frequency division is performed between frequency domain resources of feedback channels corresponding to different control channels.
That is, the resources of the feedback channel are determined according to the resource positions of the control channels, one control resource corresponds to 1 or more feedback resources according to a predefined rule, and feedback resources corresponding to different control resources are orthogonal.
For example, in combination with the above-described Slot structure shown in fig. 9, assuming that the number of control channels and feedback channels is 2 (i.e., k=j=2), and that at least K-1 slots (i.e., slot n to Slot n+k) are spaced between the control information and the feedback information, a schematic diagram of the correspondence between control resources and feedback resources is shown in fig. 12.
Or in combination with the above-mentioned Slot structure shown in fig. 11, assuming that the number of control channels and feedback channels is 2 (i.e. k=j=2), and that at least K-1 slots (i.e. Slot n to Slot n+k) are separated between the control information and the feedback information, another schematic diagram of the correspondence between the control resources and the feedback resources is shown in fig. 13.
Further, the feedback resource may be indicated by control information, i.e. the control information in the control channel may indicate at least one of the following (1) - (5):
(1) A slot offset between a slot position of at least 1 feedback channel of the second type feedback channels of the N types and a slot position of the control channel;
(2) Frequency domain resources of at least 1 feedback channel in the second type feedback channels in the N types in a designated time slot;
(3) Time domain resource indexes of at least 1 feedback channel in the second type feedback channels in the N types;
(4) Frequency domain resource index of at least 1 feedback channel of the second type feedback channels of the N types;
(5) Resource index of at least 1 feedback channel among the second type feedback channels of the N types.
That is, the resource location of the feedback channel is indicated according to control information in the control channel of the transmitting UE. And, the control information in the control channel indicates a slot offset of a slot position of the feedback resource with respect to a slot position of the control channel, and a feedback resource frequency domain position of the feedback resource in the slot, or a resource index of the feedback resource.
In this way, the corresponding relation between the control channel and the feedback channel in different time slot periods is associated through the corresponding relation between the fixed positions, and the feedback resource occupied by the feedback channel can be directly indicated through the control information in the control channel, or the two are combined for use, so that the indication mode of the feedback channel is expanded, the acquisition and the identification of the feedback channel are facilitated, and the blind detection efficiency is improved.
Illustratively, among 10 slots, feedback channels (i.e., slot periods of the feedback channels) occur at intervals of 4 slots from the 1 st slot, i.e., feedback channels occur in the 1 st, 5 th and 9 th slots of the 10 slots. If the response delay of the feedback channel a corresponding to the control channel a in the 4 th time slot is 2 time slots, the feedback channel a is not faster than the feedback channel a in the 5 th time slot, and then the feedback channel a appears in the 9 th time slot as the response of the control channel a, so that the time slot interval determined between the control channel a and the feedback channel a is 5 time slots.
It should be noted that the determination of the transmit energy on the first symbol (i.e., AGC symbol) on the time slot may be correlated with the transmit energy on the symbol occupied by any of the control channel, data channel, and feedback channel.
In some embodiments, the transmit energy of the first symbol in the slot may satisfy at least one of the following (1) - (4):
(1) The transmission energy of the first symbol in the time slot is equal to the transmission energy of the first symbol in the time domain resource of the control channel;
(2) The transmission energy of the first symbol in the time slot is equal to the transmission energy of the first symbol in the time domain resource of the feedback channel;
(3) The transmission energy of the first symbol in the time slot is equal to the transmission energy of the first symbol which is not overlapped with the time domain resource of the control channel in the time domain resource of the data channel;
(4) The transmission energy of the first symbol in the slot is equal to the transmission energy of the symbol in the slot with the greatest transmission energy except for the first symbol.
For (1) above, when the UE transmits only the control channel, the energy on the AGC symbol is equal to the transmission energy on the first symbol (i.e., the second symbol of the slot) on the control channel, as shown in fig. 14.
Or when the UE transmits both the data channel and the control channel, the energy on the AGC symbol is equal to the transmit energy on the first symbol on the control channel, as shown in fig. 15.
For the above (3), when the UE transmits only the data channel, the energy on the AGC symbol is equal to the energy on the first symbol of the symbols without control resources on the data channel, as shown in fig. 16.
For (2) above, when the UE transmits only the feedback channel and the control channel in the slot, the energy on the AGC symbol is equal to the transmission energy on the control channel or the first symbol on the feedback channel, as shown in fig. 17.
Or the UE transmits only the feedback channel in the slot, the energy on the AGC symbol is equal to the transmitted energy on the first symbol on the feedback channel, as shown in fig. 18.
Or when the UE transmits both the data channel and the feedback channel, the energy on the AGC symbol is equal to the transmit energy on the first symbol on the feedback channel, as shown in fig. 19.
For (4) above, for the transmitting UE, the energy on the first symbol in the slot is equal to the energy on the symbol with the greatest energy among all symbols transmitted by the UE in the slot.
Further, the first symbol in the slot may satisfy at least one of the following (1) - (5):
(1) The information on all resource elements on the first symbol in the slot is the same as the information on all resource elements on the second symbol in the slot;
(2) The information on all resource elements on the first symbol in the time slot is the same as the information on all resource elements on the first symbol in the time domain resource of the data channel in the time slot that is not overlapped with the time domain resource of the control channel;
(3) The information on all resource elements on the first symbol in the slot is the same as the information on all resource elements on the first symbol in the time domain resource of the control channel in the slot;
(4) The information on all resource elements on the first symbol in the slot is the same as the information on all resource elements on the first symbol in the time domain resource of the feedback channel in the slot
(5) The information on all resource elements on the first symbol in the slot is the same as the information on all resource elements on the symbol of the slot where the transmitted energy is the largest except for the first symbol.
That is, the energy determining method of the first symbol is not particularly emphasized when describing, but at least one of a control channel, a data channel, and a feedback channel to be transmitted in a slot is normally mapped when transmitting data, further, the transmitting UE copies contents on all Resource Elements (REs) on the second symbol in the slot to the first symbol, or copies contents on all REs on a symbol having the largest energy among all symbols in the slot to the first symbol.
In summary, the resource configuration signaling according to which the member node is configured by a pre-configured (e.g., factory set) or by a head node in the same D2D communication system as the member node.
The embodiment of the disclosure also provides a communication method applied to the head node, as shown in fig. 20, which may include:
S2001, sending a resource configuration signaling of a physical channel to a member node in the D2D communication system.
Wherein the physical channel may include at least one of a control channel, a data channel, and a feedback channel.
In the embodiment of the present disclosure, the resource configuration signaling is used to indicate candidate channel resources referred to when channel resource configuration is performed on any one of a control channel, a data channel, and a feedback channel.
The resource allocation signaling may include a first resource allocation signaling of a data channel, a second resource allocation signaling of a control channel, and a third resource allocation signaling of a feedback channel.
It should be noted that, for the description of the first resource configuration signaling, the second resource configuration signaling, and the third resource configuration signaling, reference may be made to the description in the foregoing embodiments, which is not repeated herein.
In some embodiments, the number of member nodes may be plural, and the plural member nodes may satisfy at least one of the following (1) - (3):
(1) The resource allocation signaling corresponding to all member nodes is the same;
(2) The resource allocation signaling corresponding to the different member nodes is different;
(3) The resource allocation signaling corresponding to part of the member nodes is the same.
That is, by differentially configuring channel resources for a plurality of member nodes, the subsequent blind detection efficiency can be improved.
Illustratively, on a control resource in the field network, a node control resource shared by member UEs may be configured, or a node control resource shared by group member UEs may be configured, or each member UE may be configured with a dedicated node control resource, and different dedicated node control resources may have different slot periods.
In addition, the head node may further send scheduling information to the member node, instruct the member node to map data channels sent to other member nodes on the first preset data channel resource, and receive data channels sent by other member nodes on the second preset data channel resource.
In this way, by directly indicating the data channel resources used between the member nodes, excessive use of control channels for indication in transmission can be avoided, so as to reduce transmission delay.
Similarly, the head node may indicate channel resource locations of the specific mapping of the control channel, the data channel and the feedback channel through the scheduling information, so as to improve the subsequent blind detection efficiency.
Illustratively, when the head node schedules the member UE to transmit data, the head node indicates the resource time-frequency position of the control resource, the resource time-frequency position of the data resource, and the member UE transmitting data transmits the control channel and the data channel, and the control channel indicates the resource time-frequency position of the data channel.
That is, between UEs in the field network, the transmission data must transmit a corresponding control channel, and the control channel is used to indicate information of the data channel.
Further, the scheduling information sent by the head node may be at a specific resource position in the control resources in the time slot, where the specific resource position is a position where the member UE specifically blindly detects the head node control resources, and may include 1 or more control channel resources.
In addition, the feedback resource position indicated by the control channel sent by the head node may be a specific resource position in the feedback resource in the time slot, or located at a specific resource position in the control resource, where the specific resource is built in to be a resource position where the head node UE receives feedback information specifically.
Or when the head node schedules the member UE to transmit data, the head node indicates the resource time-frequency position of the data resource to the member UE transmitting the data, and the member UE transmitting the data transmits a corresponding data channel according to the scheduling indication.
That is, when the member UE transmits data, only the data channel is transmitted according to the scheduling instruction of the head node, and the control channel+the data channel is transmitted when the head node transmits the data channel to the member UE.
Taking interaction between a member node and a head node as an example, the communication method provided in the foregoing embodiment is described below, as shown in fig. 21, including:
s2101, the head node sends resource configuration signaling of the physical channel to the D2D communication system member node.
S2102, the member node receives a resource allocation signaling for a physical channel sent by a head node in the same D2D communication system.
S2103, the member node determines channel resources corresponding to the physical channel based on the resource configuration signaling.
S2104, the member node performs data transmission on the channel resources corresponding to the physical channel.
