Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular to a resource determination method and related devices. Background Art

[0002] With the continuous advancement of communication technology, communication demands are also increasing. More and more communication scenarios require enhanced communication. Existing solutions for communication enhancement scenarios target scenarios where a single transmission point serves a terminal. Based on configuration information, the number of PDCCH candidates that can be monitored and the threshold for non-overlapping CCE resources that can be monitored within a timeslot / span are determined. When the number of PDCCH candidates / non-overlapping CCEs within a timeslot / span exceeds the threshold, it is necessary to specify which PDCCH candidates should be monitored for PDCCHs. It is also necessary to specify which resources corresponding to non-overlapping CCEs should be monitored for PDCCHs. To enhance cell-edge transmission reliability, two transmission points are used to serve the terminal. For scenarios with two transmission points, the number of PDCCH candidates that can be monitored and the threshold for non-overlapping CCE resources that can be monitored within a timeslot / span are determined based on configuration information. When the number of PDCCH candidates / non-overlapping CCEs within a timeslot / span exceeds the threshold, it is necessary to specify which PDCCH candidates should be monitored for PDCCHs. It is also necessary to clearly identify the resources corresponding to the non-overlapping CCEs in which to monitor the PDCCH to improve transmission accuracy. Summary of the Invention

[0096] In order to better understand a resource determination method provided in an embodiment of the present application, the following first briefly introduces a communication system to which the resource determination method is applied. Figure 1As shown, the communication system includes a first transmission point, a second transmission point, and a terminal device. The first transmission point or the second transmission point obtains high-level configuration information, and determines the target PDCCH candidates and target non-overlapping CCE in a time slot or span based on the high-level configuration information. The number of the target PDCCH candidates or target non-overlapping CCEs is not greater than the maximum number M of PDCCH candidates or the maximum number N of non-overlapping CCEs in a time slot or a span. One or more of the target PDCCH candidates or target non-overlapping CCEs are used to send PDCCH to the terminal device. The terminal device can determine the target PDCCH candidates and target non-overlapping CCE in a time slot or span based on the high-level configuration information, and monitor the resources corresponding to the target PDCCH candidates and target non-overlapping CCE in the above-mentioned time slot or span to obtain the PDCCH sent to the first transmission point or the second transmission point.

[0097] See also Figure 2A , Figure 2A The embodiment of the present application provides an interactive schematic diagram of a resource determination method. Figure 2A As shown, the resource determination method includes:

[0098] S201: A network device obtains high-level configuration information.

[0099] The network device can obtain high-layer configuration information based on high-layer signaling. The high-layer configuration information includes a first search space set and a second search space set. The second search space set corresponds to the first transmission point and the second transmission point, and the first search space set corresponds to the third transmission point. The first transmission point and the second transmission point can be the same as the third transmission point, or different transmission points.

[0100] In the embodiment of the present application, the first type of search space set may be understood as a set including the first search space set, and the second type of search space set may be understood as a set including the second search space set.

[0101] S202: The network device determines a target PDCCH candidate and a target non-overlapping CCE in a time slot or span according to high-layer configuration information.

[0102] The number of target PDCCH candidates and / or target non-overlapping CCEs is not greater than the maximum number M of PDCCH candidates or the maximum number N of non-overlapping CCEs in a time slot or a span. The maximum number M of PDCCH candidates or the maximum number N of non-overlapping CCEs in a time slot or a span may be determined in a predefined manner or through high-level configuration information and is not specifically limited here.

[0103] S203: The network device sends a PDCCH through resources corresponding to the target PDCCH candidate and the target non-overlapping CCE.

[0104] The network device can also obtain high-level configuration information and determine the target PDCCH candidate and target non-overlapping CCE in a time slot or span based on the high-level configuration information. The specific implementation method is the same as the network device determining the target PDCCH candidate and target non-overlapping CCE in a time slot or span.

[0105] S204. The terminal device determines a PDCCH monitoring behavior according to the target PDCCH candidate and the resources corresponding to the target non-overlapping CCE.

[0106] The terminal device may determine the target PDCCH candidate and target non-overlapping CCE in a time slot or span based on high-layer configuration information. After determining the target PDCCH candidate and target non-overlapping CCE in a time slot or span, the terminal device determines the PDCCH monitoring behavior based on the resources corresponding to the target PDCCH candidate and the target non-overlapping CCE.

[0107] Since the network device determines the behavior of sending PDCCH through the resources corresponding to the target PDCCH candidate and the target non-overlapping CCE, the sending method can be to send PDCCH in a part of the target PDCCH candidate or the target non-overlapping CCE, and the terminal device can monitor PDCCH from this part.

[0108] In one possible implementation, the first type of search space set includes a first set and a second set. A possible method for determining, based on the higher-layer configuration information, a target PDCCH candidate and a target non-overlapping CCE in a time slot or span includes:

[0109] A1. Obtain a first set and a second set in the first type of search space sets, wherein a maximum search space set identifier j of the search space sets in the first set is smaller than a minimum search space set identifier i of the search space sets in the second set;

[0110] A2. If the number B1 of PDCCH candidates corresponding to the second search space set is not greater than M and the sum of the numbers A1 and B1 of PDCCH candidates corresponding to the first search space set is greater than M, then determine the PDCCH candidates corresponding to the first set and the second search space set as the target PDCCH candidates;

[0111] A3. If the number B2 of non-overlapping CCEs corresponding to the second search space set is not greater than N, and the sum of the numbers A2 and B2 of non-overlapping CCEs corresponding to the first search space set is greater than N, determine the non-overlapping CCEs corresponding to the first set and the second search space set as the target non-overlapping CCEs;

[0112] The number of target PDCCH candidates is X, the sum of the number of PDCCH candidates x corresponding to the search space set identifier i and X is greater than M, the number of target non-overlapping CCE candidates is Y, and the sum of the number of non-overlapping CCEs y corresponding to the search space set identifier i and Y is greater than N.

[0113] In the above method, when the number B1 of PDCCH candidates corresponding to the second type of search space set is not greater than M, the target PDCCH candidate is determined from the PDCCH candidates corresponding to the second type of search space set in the first type of search space set, and the method for determining the target non-overlapping CCE is the same as that for determining the target PDCCH candidate.

[0114] In a specific embodiment, Figure 2BAs shown, the time slot is used as an example for explanation, where USS2 and USS3 are the first type of search space sets, USS2 includes 2 PDCCH candidates, and USS3 includes 6 PDCCH candidates. The first type of search space set corresponds to the third transmission point, and USS5 and USS7 are the second type of search space sets. In each corresponding time slot, they can correspond to the first transmission point and the second transmission point, and of course can also correspond to one transmission point. USS5 includes 4 PDCCH candidates, and USS7 includes 8 PDCCHs. If each time slot corresponding to USS5 and USS7 corresponds to the first transmission point and the second transmission point, and if the maximum number of PDCCH candidates in a time slot is 19, the first set includes USS2 and the second set includes USS3, then the PDCCH candidates corresponding to USS5, USS7, and USS2 can be determined as the target PDCCH candidates. For another example, if the maximum number of PDCCH candidates in a time slot is 16, the second set includes USS3 and USS2, and the first set is empty, then the PDCCH candidates corresponding to USS5 and USS7 can be determined as the target PDCCH candidates.

[0115] In one possible implementation, another method for determining a target PDCCH candidate / target non-overlapping CCE includes:

[0116] B1. If the number B1 of PDCCH candidates corresponding to the second search space set is greater than M, and the sum of the numbers A1 and B1 of PDCCH candidates corresponding to the first search space set is greater than M, or the number B2 of non-overlapping CCEs corresponding to the second search space set is greater than N, and the sum of the numbers A2 and B2 of non-overlapping CCEs corresponding to the first search space set is greater than N, then obtain a third set and a fourth set in the second search space set, where the third set corresponds to the first transmission point, and the fourth set corresponds to the second transmission point;

[0117] B2. Acquire a first subset and a second subset in the third set, wherein the maximum search space set identifier p of the search space set in the first subset is smaller than the minimum search space set identifier q of the search space set in the second subset;

[0118] B3. Determine that the PDCCH candidates corresponding to the first subset and the fourth set are the target PDCCH candidates and the non-overlapping CCEs corresponding to the first subset and the fourth set are the target non-overlapping CCEs;

[0119] Among them, the number of target PDCCH candidates is H, the sum of the number of PDCCH candidates h corresponding to the search space set identifier q and H is greater than M, the number of target non-overlapping CCEs is K, and the sum of the number of non-overlapping CCEs k corresponding to the search space set identifier q and K is greater than N.

[0120] In the above method, after determining that the number B1 of PDCCH candidates corresponding to the second search space set is greater than M, the target PDCCH candidate is directly determined from the second search space set. The method for determining the target non-overlapping CCE is the same as that for determining the target PDCCH candidate.

[0121] In a specific embodiment, Figure 2C As shown, the time slot is used as an example for explanation, where USS2 and USS3 are the first type of search space sets, USS2 includes 2 PDCCH candidates, and USS3 includes 6 PDCCH candidates. The first type of search space set corresponds to the third transmission point, and USS5 and USS7 are the second type of search space sets. In each corresponding time slot, they can correspond to the first transmission point and the second transmission point, and of course can also correspond to one transmission point. USS5 includes 2 PDCCH candidates, and USS7 includes 4 PDCCHs.

[0122] In USS7, there are two search space sets corresponding to the first transmission point and two search space sets corresponding to the second transmission point.

[0123] If each time slot corresponding to USS5 and USS7 corresponds to a first transmission point and a second transmission point, and if the maximum number of PDCCH candidates in a time slot is 4, then the first subset in the third set includes two PDCCH candidates corresponding to the second transmission point, and the second subset includes two PDCCH candidates corresponding to the first transmission point. Then, the target PDCCH candidate includes the PDCCH candidate corresponding to USS5 and the two PDCCH candidates corresponding to the second transmission point in USS7.

[0124] In a possible implementation, the second type of search space set includes a first group of search space sets and a second group of search space sets; the first group of search space sets corresponds to the first transmission point, and the second group of search space sets corresponds to the second transmission point;

[0125] Another possible method for determining a target PDCCH candidate and a target non-overlapping CCE in a time slot / span according to the higher layer configuration information includes:

[0126] C1. Determine a first set and a second set in the first type of search space set and the first group of search space sets, wherein the maximum search space set identifier j of the search space sets in the first set is smaller than the minimum search space set identifier i of the search space sets in the second set;

[0127] C2. If the sum of the number A1 of PDCCH candidates corresponding to the first search space set and the number B1 of PDCCH candidates corresponding to the second search space set is greater than M, determining the PDCCH candidates corresponding to the first set and the second search space set as the target PDCCH candidates;

[0128] C3. If the sum of the number A2 of non-overlapping CCEs corresponding to the first search space set and the number B2 of non-overlapping CCEs corresponding to the second search space set is greater than N, determining the non-overlapping CCEs corresponding to the first set and the second search space set as target non-overlapping CCEs;

[0129] The number of target PDCCH candidates is X, the sum of the number of PDCCH candidates x corresponding to the search space set identifier i and X is greater than M, the number of target non-overlapping CCEs is Y, and the sum of the number of non-overlapping CCEs y corresponding to the search space set identifier i and Y is greater than N.

[0130] In the above embodiment, it can be understood that the target PDCCH candidates and the target non-overlapping CCEs are determined from low to high according to the search space set identifiers.

[0131] In a specific embodiment, Figure 2D As shown, here the time slot is used as an example for explanation. The PDCCH corresponding to the first transmission point in USS7 and USS5 can be determined as the corresponding PDCCH candidate in the first group of search space sets, and the PDCCH corresponding to the second transmission point in USS7 and USS5 can be determined as the corresponding PDCCH candidate in the second group of search spaces. If the threshold value M of the PDCCH candidate is 10, it can be determined that the first set includes: USS2, USS3, and the second set includes USS7 and USS5. The PDCCH candidates corresponding to USS2 and USS3 and the PDCCH corresponding to the second transmission point in USS7 and USS5 are determined as target PDCCH candidates.

[0132] In one possible implementation, the resource determination method may determine a correspondence between a TCI state and a first transmission point and a second transmission point, specifically including:

[0133] D1. Acquire a first TCI state and a second TCI state according to the high-layer configuration information, where the first TCI state and the second TCI state correspond to a control resource set, and the first TCI state is configured before the second TCI state;

[0134] D2. Determine that the first TCI state or the second TCI state corresponds to a first transmission point; or determine that a TCI state with a maximum or minimum identifier in the first TCI state or the second TCI state corresponds to the first transmission point.

[0135] Specifically, it can be understood that one control resource set corresponds to a first TCI state and a second TCI state, and the first TCI state is configured before the second TCI state.

[0136] In one possible implementation, the second type of search space set corresponds to at least two second search space sets, the coreset corresponds to the first TCI state and the second TCI state, the first TCI state is before the second TCI state, and further includes a method for corresponding to the second search space set in the second type of search space set of the TCI state, specifically as follows:

[0137] E1. The search space set with the smallest index value in the two second search space sets corresponds to the first TCI state or the second TCI state;

[0138] E2. Alternatively, the search space set with the smallest index value in the two second search space sets corresponds to the TCI state with the smaller index value in the first TCIstate and the second TCI state;

[0139] E3. Alternatively, the search space set with the smallest index value in the two second search space sets corresponds to the TCI state with the larger index value in the first TCIstate and the second TCI state;

[0140] E4. Alternatively, the search space set with an earlier starting time in the time domain resources corresponding to the two second search space sets corresponds to the first TCI state or the second TCI state.

[0141] E5. Alternatively, the search space set with an earlier start time in the time domain resources corresponding to the two second search space sets corresponds to the TCI state with the smallest / largest index value in the first TCI state and the second TCI state.

[0142] Optionally, when two second search space sets overlap in the time domain, or when FDM is used, the PDCCH candidate resources are distributed in different search space sets as follows:

[0143] Option 1: Split the entire Coreset resource into two parts: the first half CCEs for TRP1 (the first TCI state in Coreset) and the second half CCEs for TRP2 (the second TCI state in Coreset), where TRP1 is the first transmission point and TRP2 is the second transmission point.

[0144] Option 2: Place the PDCCH candidate corresponding to TRP2 behind the PDCCH candidate of TRP1.

[0145] Option 3: The PDCCH candidates of TRP1 and TRP2 are arranged in an interleaved manner.

[0146] In one possible implementation, a method for controlling the correspondence between resource sets and transmission points is further provided, specifically including:

[0147] F1. Obtain the first coreset control resource pool index value and the second coreset control resource pool index value according to high-level configuration information;

[0148] F2. Determine that the control resource set with the smallest control resource set pool index value corresponds to the first transmission point.

[0149] The above mainly introduces the scheme of the embodiment of the present application from the perspective of the execution process on the method side. It is understandable that, in order to implement the above functions, the terminal includes hardware structures and / or software modules corresponding to the execution of each function.
