"And/or", which describes the association relationship of the associated objects, means that there can be three kinds of relationships, for example, A and/or B, which can mean that A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In the text description of this application, the character "/" generally indicates that the contextual object is an "or" relationship.

The method for determining scheduling resources provided by the embodiments of the present application can be applied to a scenario in which scheduling resources are configured. When a terminal sends uplink data or reference signals through scheduling resources; or receives downlink data or reference signals through scheduling resources, the base station needs to first configure scheduling resources for multiple PDCCHs through configuration information in high-level signaling. For example, scheduling resources can be physical. Downlink shared channel (physical downlink shared channel, PDSCH), physical uplink shared channel (physical uplink shared channel, PUSCH) or uplink and downlink reference signals, etc. In the prior art, when multiple PDCCHs are configured with scheduling resources at the base station, only PDCCHs are supported to independently schedule different scheduling resources. The specific configuration process is as follows: the base station needs to configure scheduling resources for each PDCCH through high-layer signaling. Wherein, the high-level signaling includes the time slot offset of each scheduling resource relative to the PDCCH configured by the high-level signaling and the configuration information of the scheduling resource, so that the terminal can make the terminal according to the time slot offset of the scheduling resource relative to the PDCCH and the PDCCH. The configuration information of the scheduling resources determines the scheduling resources of the PDCCH, so that uplink data or reference signals are sent through the scheduling resources; or downlink data or reference signals are received through the scheduling resources.

For example, taking the base station configuring scheduling resources for PDCCH1, PDCCH2, and PDCCH3 through high-layer signaling as an example, it can be combined with FIG. 1, which is a schematic diagram of a prior art provided by this embodiment of the present application. Different scheduling resources are scheduled. PDCCH1 schedules scheduling resource 1, PDCCH2 schedules scheduling resource 2, and PDCCH3 schedules scheduling resource 3. When the base station configures scheduling resources for PDCCH1, PDCCH2, and PDCCH3, it can configure scheduling resource 1 for PDCCH1, configure scheduling resource 2 for PDCCH2, and configure scheduling resource 3 for PDCCH3 through high-layer signaling; wherein, the high-level signaling includes scheduling resource 1 relative to the time slot offset 1 of the PDCCH1 and the configuration information of the scheduling resource 1, so that the terminal determines the scheduling resource 1 of the PDCCH1 according to the scheduling resource 1 relative to the time slot offset 1 of the PDCCH1 and the configuration information of the scheduling resource 1; And the high-level signaling includes the time slot offset 2 of the scheduling resource 2 relative to the PDCCH2 and the configuration information of the scheduling resource 2, so that the terminal is based on the time slot offset 2 of the scheduling resource 2 relative to the PDCCH2 and the scheduling resource 2. The configuration information of the PDCCH1 determines the scheduling resource 2 of the PDCCH1; and the high-level signaling includes the time slot offset 3 of the scheduling resource 3 relative to the PDCCH3 and the configuration information of the scheduling resource 3, so that the terminal is based on the scheduling resource 3 relative to the PDCCH3. The time slot offset 3 and the configuration information of the scheduling resource 3 determine the scheduling resource 3 of the PDCCH1, so that different scheduling resources 1, 2 and 3 are independently configured for the PDCCH1, PDCCH2 and PDCCH3.

In order to improve the reliability of PDCCH transmission, an attempt may be made to schedule the same scheduling resource for multiple PDCCHs. 2 is a schematic diagram of a scenario provided by an embodiment of the present application. Taking multiple PDCCHs including PDCCH1, PDCCH2, and PDCCH3 as an example, based on the existing configuration method for independently scheduling different scheduling resources for PDCCHs, the base station is When configuring target scheduling resources for PDCCH1, PDCCH2, and PDCCH3, the specific implementation process may be as follows: the base station may configure target scheduling resources for PDCCH1, configure target scheduling resources for PDCCH2, and configure target scheduling resources for PDCCH3 through high-level signaling; The signaling includes the time slot offset 1 of the target scheduling resource relative to the PDCCH1 and the configuration information of the target scheduling resource, so that the terminal can configure the target scheduling resource according to the time slot offset 1 of the target scheduling resource relative to the PDCCH1 and the target scheduling resource. The information determines the target scheduling resource; and the high-level signaling includes the time slot offset 2 of the target scheduling resource relative to the PDCCH2 and the configuration information of the target scheduling resource, so that the terminal is offset according to the target scheduling resource relative to the time slot of the PDCCH2. Quantity 2 and the configuration information of the target scheduling resource determine the target scheduling resource; and the high-level signaling includes the time slot offset 3 of the target scheduling resource relative to the PDCCH3 and the configuration information of the target scheduling resource, so that the terminal is relative to the target scheduling resource according to the target scheduling resource. The target scheduling resource is determined based on the time slot offset 3 of the PDCCH3 and the configuration information of the target scheduling resource, so that the same target scheduling resource can be scheduled for PDCCH1, PDCCH2 and PDCCH3, which can further improve the reliability of the scheduling information.

However, when this scheduling scheme is used to schedule the same target scheduling resource for PDCCH1, PDCCH2 and PDCCH3, since the same target scheduling resource is configured for PDCCH1, PDCCH2 and PDCCH3, the target scheduling resource configured for PDCCH1 in the higher layer signaling The configuration information of the target scheduling resource, the configuration information of the target scheduling resource configured for PDCCH2, and the configuration information of the target scheduling resource configured for PDCCH3 are all the same configuration information, which will lead to high overhead signaling.

Therefore, in order to realize the scheduling of the same target scheduling resource on multiple PDCCHs while reducing the overhead of high-level signaling, it is considered that the configuration information of the target scheduling resource can be indicated to multiple PDCCHs through the configuration information of the same target scheduling resource. , when indicating the time slot offset of the target scheduling resource relative to multiple PDCCHs to the terminal, considering that there is already a field in the original protocol to indicate the time slot offset of the scheduling resource relative to the PDCCH, in order not to change the original protocol, when indicating the time slot offset of the target scheduling resource relative to multiple PDCCHs to the terminal, the time slot offset indicated by the field in the original protocol can continue to be used. However, in the actual scheduling process, due to the target scheduling resource Compared with the different time slot offsets of each PDCCH, the terminal cannot accurately find the target scheduling resource only by the time slot offset indicated by the field. Therefore, in order to enable the terminal to use the time slot offset indicated by the field in the original protocol To accurately find the target scheduling resource, you can try to additionally indicate an offset to the terminal for each PDCCH, so that the terminal can additionally indicate to the terminal according to the time slot offset indicated by the field in the original protocol and for each PDCCH. The terminal further indicates an offset to jointly determine the target scheduling resource.

Based on the above technical concept, an embodiment of the present application provides a method for determining scheduling resources. A network device sends a high-level signaling to a terminal, and the high-level signaling includes the target scheduling resource relative to each PDCCH in the PDCCHs of multiple physical downlink control channels. The initial time slot offset and the configuration information of the target scheduling resource, and multiple PDCCHs are used to schedule the target scheduling resource; and determine the additional time slot offset of the target scheduling resource relative to each PDCCH; Indication information of the additional time slot offset of the scheduling resource relative to each PDCCH; in this way, the terminal can be based on the initial time slot offset of the target scheduling resource relative to each PDCCH, the configuration information of the target scheduling resource, and the target scheduling resource relative to each PDCCH. The additional slot offsets of , together determine the target scheduling resource.

For example, the target scheduling resource may be PDSCH, PUSCH, or uplink and downlink reference signals, etc., which may be set according to actual needs. Here, the type of the target scheduling resource is not further limited in this embodiment of the present application.

Illustratively, in this embodiment of the present application, the configuration information of the target scheduling resource may include the starting position of the target scheduling resource in the time slot and the number of symbols occupied by the target scheduling resource in the time slot, and of course, may also include other information. , here, the embodiment of the present application only takes the configuration information of the target scheduling resource including the starting position of the target scheduling resource in the time slot and the number of symbols occupied by the target scheduling resource in the time slot as an example for description, but does not It represents that the embodiments of the present application are only limited to this.

It can be understood that, in the embodiment of the present application, the target scheduling resource included in the high-level signaling is relative to the initial time slot offset of each PDCCH in the multiple physical downlink control channels PDCCH, that is, the field in the original protocol. The offset of the indicated scheduling resource relative to the PDCCH. For multiple PDCCHs, the initial slot offset is the same, just because the same initial slot offset indicated by the field cannot accurately indicate the target Scheduling resources, therefore, an additional offset is indicated to the terminal for each PDCCH, so that the terminal can additionally indicate to the terminal according to the time slot offset indicated by the field in the original protocol and for each PDCCH. An offset together determines the target scheduling resource.

In addition, in this embodiment of the present application, the terminal is jointly determined according to the initial time slot offset of the target scheduling resource relative to each PDCCH, the configuration information of the target scheduling resource, and the additional time slot offset of the target scheduling resource relative to each PDCCH. The essence of the target scheduling resource is: the network device will first send the PDCCH to the terminal at the time slot position of each PDCCH in the multiple PDCCHs. Correspondingly, the terminal will receive all or part of the PDCCHs in the multiple PDCCHs. And for all PDCCHs in the received multiple PDCCHs or PDCCHs in some PDCCHs, according to the initial slot offset of the target scheduling resource relative to the PDCCH and the additional slot offset of the target scheduling resource relative to the PDCCH are common. Determine the time slot offset of the target scheduling resource relative to the PDCCH, and then jointly determine the target of the PDCCH according to the time slot position of the PDCCH, the time slot offset of the target scheduling resource relative to the PDCCH, and the configuration information of the target scheduling resource. Schedule resources. Therefore, it can be seen that in this embodiment of the present application, the terminal is based on the initial time slot offset of the target scheduling resource relative to each PDCCH, the configuration information of the target scheduling resource, and the additional time slot offset of the target scheduling resource relative to each PDCCH. When the target scheduling resources are jointly determined by the number of PDCCHs, the PDCCHs are all PDCCHs in the multiple PDCCHs received by the terminal or PDCCHs in part of the PDCCHs, excluding PDCCHs that are not received by the terminal.

Exemplarily, in this embodiment of the present application, when the network device sends the indication information including the additional time slot offset of the target scheduling resource relative to each PDCCH to the terminal, the indication information may be carried in the high-level signaling, or may be carried In the message content of the PDCCH, of course, it can also be carried in other messages, which can be set according to actual needs. Here, the embodiment of this application only indicates that the information can be carried in the high-level signaling or carried in the message content of the PDCCH. An example is used for description, but it does not mean that the embodiments of the present application are limited to this.

It can be seen that when multiple PDCCHs are configured to schedule the same target scheduling resource, the initial time slot offset of the target scheduling resource relative to each PDCCH and the configuration information of the target scheduling resource are sent to the terminal through high-level signaling, and the After the additional time slot offset of the target scheduling resource relative to each PDCCH, the additional time slot offset of the target scheduling resource relative to each PDCCH is sent to the terminal through the indication information, so that the terminal can be relative to each PDCCH according to the target scheduling resource. The initial time slot offset of , the configuration information of the target scheduling resource and the additional time slot offset of the target scheduling resource relative to each PDCCH jointly determine the target scheduling resource, so that multiple PDCCHs can schedule the same target scheduling resource. Moreover, the initial time slot offset of a target scheduling resource relative to each PDCCH and the configuration information of the target scheduling resource are indicated to the terminal through high-layer signaling, which effectively reduces the overhead of high-layer signaling.

It should be noted that, in the technical solution of the present application, by setting indication information for multiple PDCCHs, the indication information includes the additional time slot offset of the target scheduling resource relative to each PDCCH, so that the terminal is offset according to the initial time slot. and the additional time slot offset of the target scheduling resource relative to each PDCCH to determine the time slot offset of the target scheduling resource relative to each PDCCH; of course, it can also be multiple search spaces or control resource sets (control resource set, CORESET) ) Set the indication information, so that the time slot offset of the target scheduling resource relative to each PDCCH is determined according to the indication information set for multiple search spaces or. Among them, CORESET is used to indicate the resource size occupied by the PDCCH; the search space is used to indicate the number of PDCCH candidates and slot positions, and by associating a CORESET, the time-frequency domain resource positions of the PDCCH candidates can be completely determined.

Hereinafter, the method for determining scheduling resources provided by the embodiments of the present application will be described in detail through detailed embodiments. It can be understood that, in the embodiments of the present application, the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 3 is a schematic flowchart of a method for determining scheduling resources provided by an embodiment of the present application. The method for determining scheduling resources may be performed by software and/or hardware devices. For an example, please refer to FIG. 3 . Determination methods can include:

S301. The network device sends high-layer signaling to the terminal.

The high layer signaling includes the initial slot offset of the target scheduling resource relative to each PDCCH in the multiple physical downlink control channels PDCCH and the configuration information of the target scheduling resource, and the multiple PDCCHs are all used for scheduling the target scheduling resource.

For example, please refer to FIG. 4, which is a schematic diagram of a PDCCH and target scheduling resources provided by an embodiment of the present application. Similarly, taking multiple PDCCHs including PDCCH1, PDCCH2, and PDCCH3 as an example, the network equipment is PDCCH1, PDCCH2. And when PDCCH3 is configured with the same target scheduling resource, the initial time slot offset and the configuration information of the target scheduling resource can be configured for the terminal through high-level signaling in advance, and the high-level signaling can include the target scheduling resource relative to the initial time of PDCCH1. The slot offset, the initial slot offset of the target scheduling resource relative to PDCCH2, the initial slot offset of the target scheduling resource relative to PDCCH3, and the configuration information of the co-scheduled target scheduling resource. Among them, the initial slot offset of the target scheduling resource relative to PDCCH1, the target scheduling resource relative to the initial slot offset of PDCCH2, and the target scheduling resource relative to the initial slot offset of PDCCH3 have the same values, which are both The slot offset indicated by the field in the original protocol.

However, since only indicating the same initial slot offset indicated by the field in the original protocol cannot accurately indicate the target scheduling resource, the network device needs to additionally indicate an additional slot offset to the terminal for each PDCCH. , so that the terminal can jointly determine the target scheduling resource according to the time slot offset indicated by the field in the original protocol and the additional time slot offset relative to each PDCCH for the target scheduling resource.

S302. Send indication information to the terminal.

The indication information includes an additional time slot offset of the target scheduling resource relative to each PDCCH, and the additional time slot offset of the target scheduling resource relative to each PDCCH is preconfigured by the network device according to the time slot position of the target scheduling resource.

As shown in FIG. 4 , continuing to take multiple PDCCHs including PDCCH1, PDCCH2 and PDCCH3 as an example, the indication information includes the additional time slot offset 1 of the target scheduling resource relative to PDCCH1, and the additional time slot of the target scheduling resource relative to PDCCH2. Offset 2, and additional slot offset 3 of the target scheduling resource relative to PDCCH3.

Exemplarily, the indication information may be configured to each PDCCH through higher layer signaling. Or, the indication information is carried in the message content of each PDCCH. It can be understood that when multiple PDCCHs are configured to schedule the same target scheduling resource, the additional time slot offset of the target scheduling resource relative to each PDCCH is configured to each PDCCH through high-level signaling. The advantage of this is that there is no need to modify the PDCCH. In the DCI, multiple PDCCHs can be used to schedule the same scheduling resource. The additional time slot offset of the target scheduling resource relative to each PDCCH is carried in the message content of the PDCCH and indicated to the terminal. The advantage of this is that the upper layer does not need to modify the configuration, but only needs to modify the DCI in the PDCCH to realize multiple PDCCHs Schedule the same scheduling resource.

After the network device preconfigures the time slot position of the target scheduling resource, the initial time slot offset of the target scheduling resource relative to each PDCCH, and the additional time slot offset of the target scheduling resource relative to each PDCCH, it can The time slot position of the configured target scheduling resource, the initial time slot offset of the target scheduling resource relative to each PDCCH, and the additional time slot offset of the target scheduling resource relative to each PDCCH determine the time slot position of each PDCCH; and Send the PDCCH to the terminal at the time slot position of each PDCCH, so that the terminal can acquire each PDCCH, that is, perform the following S303:

S303, the network device sends the PDCCH to the terminal at the time slot position of each PDCCH.

It should be noted that, in this embodiment of the present application, if the indication information including the additional time slot offset of the target scheduling resource relative to each PDCCH is configured to each PDCCH through high-layer signaling, when the network device sends the PDCCH to the terminal, the There is no need to carry the indication information in the message content of the PDCCH; on the contrary, if the indication information including the additional time slot offset of the target scheduling resource relative to each PDCCH is not configured to each PDCCH through high-level signaling, the network device will send the message to the terminal. When sending the PDCCH, the message content of the PDCCH needs to carry indication information, so that the indication information is sent to the terminal through the message content of the PDCCH.

As shown in FIG. 4 , continuing to take multiple PDCCHs including PDCCH1, PDCCH2 and PDCCH3 as an example, the network device preconfigures the time slot position of the target scheduling resource, the initial time slot offset of the target scheduling resource relative to PDCCH1, and the target scheduling resource. After the additional time slot offset of the scheduling resource relative to PDCCH1 is 1, the pre-configured time slot position of the target scheduling resource, the initial time slot offset of the target scheduling resource relative to PDCCH1, and the target scheduling resource relative to PDCCH1 can be used. The extra time slot offset 1 determines the time slot position of PDCCH1; and sends PDCCH1 to the terminal at the time slot position of PDCCH1, so that the terminal can obtain PDCCH1; After the initial time slot offset of PDCCH2 and the additional time slot offset 2 of the target scheduling resource relative to PDCCH2, the preconfigured time slot position of the target scheduling resource and the initial time slot of the target scheduling resource relative to PDCCH2 can be used. The offset, and the additional time slot offset 2 of the target scheduling resource relative to PDCCH2 determine the time slot position of PDCCH2; and send PDCCH2 to the terminal at the time slot position of PDCCH2, so that the terminal can obtain PDCCH2; The time slot position of the target scheduling resource, the initial time slot offset of the target scheduling resource relative to PDCCH3, and the additional time slot offset of the target scheduling resource relative to PDCCH3 After 3, the time slot of the target scheduling resource can be scheduled according to the pre-configured The position, the initial slot offset of the target scheduling resource relative to PDCCH3, and the additional slot offset 3 of the target scheduling resource relative to PDCCH1 determine the slot position of PDCCH3; and send PDCCH3 to the terminal at the slot position of PDCCH3 , so that the terminal can obtain PDCCH3.

S304. The terminal determines the target scheduling resource according to the initial time slot offset of the target scheduling resource relative to each PDCCH, the configuration information of the target scheduling resource, and the additional time slot offset of the target scheduling resource relative to each PDCCH.

It can be understood that, after the network device sends the PDCCH to the terminal at the time slot position of each PDCCH, the terminal can determine the time slot position of each PDCCH based on the received PDCCHs. The initial slot offset and the additional slot offset of the target scheduling resource relative to each PDCCH determine the slot offset of the target scheduling resource relative to each PDCCH, and then determine the slot offset relative to each PDCCH of the target scheduling resource based on the slot offset of the target scheduling resource relative to each PDCCH The target scheduling resources scheduled by each PDCCH are determined according to the amount, the configuration information of the target scheduling resources, and the time slot positions of each PDCCH.

Continuing to combine as shown in FIG. 4 , when the terminal determines the target scheduling resources scheduled by PDCCH1, PDCCH2 and PDCCH3, the terminal can determine the relative value of the target scheduling resources according to the initial time slot offset and the additional time slot offset 1 of the target scheduling resources relative to PDCCH1. According to the time slot offset of PDCCH1, and according to the time slot offset of the target scheduling resource relative to PDCCH1, the configuration information of the target scheduling resource and the time slot position of PDCCH1, accurately find the target scheduling resource scheduled by PDCCH1; similarly, The terminal can determine the slot offset of the target scheduling resource relative to PDCCH2 according to the initial slot offset and the additional slot offset 2 of the target scheduling resource relative to PDCCH2, and determine the slot offset of the target scheduling resource relative to PDCCH2 according to the slot offset of the target scheduling resource relative to PDCCH2. The shift amount, the configuration information of the target scheduling resource and the time slot position of the PDCCH2 can accurately find the target scheduling resource scheduled by the PDCCH2; the terminal can accurately find the target scheduling resource scheduled by the PDCCH2 according to the initial time slot offset and the target scheduling resource. The additional time slot offset 1 of the PDCCH3 Determine the time slot offset of the target scheduling resource relative to PDCCH3, and accurately find the target scheduling of PDCCH3 scheduling according to the time slot offset of the target scheduling resource relative to PDCCH3, the configuration information of the target scheduling resource, and the time slot position of PDCCH3 resources, so that PDCCH1, PDCCH2 and PDCCH3 can schedule the same target scheduling resource.

It can be seen that when multiple PDCCHs are configured to schedule the same target scheduling resource, the initial time slot offset of the target scheduling resource relative to each PDCCH and the configuration information of the target scheduling resource are sent to the terminal through high-level signaling, and the The message content of the PDCCH sends the additional time slot offset of the target scheduling resource relative to each PDCCH to the terminal, so that the terminal can make the terminal according to the initial time slot offset of the target scheduling resource relative to each PDCCH, the configuration information of the target scheduling resource and the target scheduling The resource relative to the additional time slot offset of each PDCCH jointly determines the target scheduling resource, so that multiple PDCCHs can schedule the same target scheduling resource. Moreover, the initial time slot offset of a target scheduling resource relative to each PDCCH and the configuration information of the target scheduling resource are indicated to the terminal through high-layer signaling, which effectively reduces the overhead of high-layer signaling.
