Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a PDCCH detection method, apparatus, terminal and storage medium. Background Technology

[0002] In communication systems, larger subcarrier spacing can be introduced. However, as the subcarrier spacing increases, the symbol length becomes shorter, which can affect the monitoring of the Physical downlink control channel (PDCCH).

[0003] When the beam direction corresponding to the PDCCH monitoroccasion of different control resource sets (CORESET) is different, beam switching is required. Since the subcarrier spacing (SCS) increases, the length of the cyclic prefix (CP) becomes shorter, and the beam switching time may exceed the length of the CP. Summary of the Invention

[0004] To address the problems existing in the prior art, this application provides a PDCCH detection method, apparatus, terminal, and storage medium.

Here, the fourth CORESET is a CORESET whose time interval between the PDCCH listening time of the third CORESET is less than a threshold value.

[0077] Figure 11 This is a schematic diagram of the PDCCH detection device provided in the embodiments of this application. Detailed Implementation

[0078] To facilitate a clearer understanding of the various embodiments of this application, some relevant background knowledge will be introduced as follows.

[0079] (1) Beam switching;

[0080] Beam switching needs to meet certain time requirements. With a lower SCS configuration, OFDM symbols are longer, and beam switching can be completed within the OFDM CP. However, when the SCS configuration is larger at high frequencies, such as when the subcarrier spacing is 480kHz or 960kHz, beam switching may require a symbol length interval. In this case, two adjacent CORESETs with different beam directions that do not meet the interval time cannot be received simultaneously.

[0081] To avoid this beam switching situation, network-side equipment needs to ensure that the time-domain resource interval between two CORESETs with different beam directions is greater than the beam switching time when configuring CORESET resources. This will limit the flexibility of the base station in controlling resource configuration and lead to resource shortage.

[0082] (2) There are overlapping PDCCH monitoring occasions in CORESET;

[0083] In a communication system, when a User Equipment (UE) needs to detect multiple PDCCH blind detection candidate resources on a bandwidth portion (BWP), if different cores correspond to different receive beams and the cores overlap, the process is to use only the beam corresponding to the highest priority core. Different component carriers (CCs) must use the same Transmission Configuration Indicator (TCI) state at the same time. The priority is determined by the Common Search Space (CSS) being higher than the UE special Search Space (USS). When both are CSS or USS, a lower cell index indicates higher priority; when cell indexes are the same, a smaller search space index indicates higher priority. If different cores correspond to different receive beams and the cores do not overlap, each core uses its own beam for reception, requiring receive beam switching. This switching can occur within the CP time of the corresponding OFDM symbol.

[0084] Since the processing only addresses the case where PDCCH monitoring occasions of different CORESETs overlap, it does not consider the case where the beam switching time is insufficient. When the SCS increases and the CP length decreases, the beam switching time may exceed the length of the CP. In this case, the time interval between PDCCH monitoring occasions of different CORESETs needs to be greater than a certain length before beam switching can be performed and each of the respective beam directions can be used for reception. Otherwise, only the beam direction of the PDCCH monitoring occasion of one CORESET can be selected for reception.

[0085] To overcome the above-mentioned defects, this application provides a PDCCH detection method, which can detect PDCCH in the beam direction corresponding to the PDCCH listening time of at least one target CORESET by determining the PDCCH listening time of at least one target CORESET.

[0086] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0087] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN.

[0092] Network devices and terminal devices can each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multiple-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission, etc.

[0093] Figure 1 This is one of the flowcharts illustrating the PDCCH detection method provided in the embodiments of this application, such as... Figure 1 As shown, this application provides a PDCCH detection method, the execution subject of which can be a terminal, such as a mobile phone. The method includes the following steps 101 to 102:

[0094] Step 101: Among the physical downlink control channel (PDCCH) listening opportunities of at least two control resource sets (CORESET), determine the PDCCH listening opportunity of at least one target CORESET.

[0095] Specifically, the terminal can determine the PDCCH listening time of at least one target CORESET in at least two CORESET PDCCH listening times, such that the time interval between the PDCCH listening times of any two target CORESETs corresponding to different beam directions in the at least one target CORESET PDCCH listening time is greater than or equal to a threshold value, that is, it can be guaranteed that the time domain resource interval between any two target CORESETs in different beam directions is greater than the beam switching time.

[0096] For example, the terminal can judge all pairwise combinations corresponding to the PDCCH listening times of at least two CORESETs and obtain the judgment result of each pairwise combination. Each pairwise combination includes two CORESETs, and the judgment result of each pairwise combination is used to indicate whether the time domain resource interval between the two CORESETs in the corresponding pairwise combination meets the time requirement of beam switching. Then, based on the judgment result of each pairwise combination, the terminal can determine the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two CORESETs.

[0097] For example, the terminal can sort at least two CORESETs to obtain a sorting A corresponding to the at least two CORESETs. Then, based on sorting A, the terminal can judge the pairwise combinations corresponding to the PDCCH listening times of the at least two CORESETs to obtain the judgment result of at least one pairwise combination. Here, any pairwise combination includes two CORESETs, and the judgment result of any pairwise combination is used to indicate whether the time domain resource interval between the two CORESETs in the corresponding pairwise combination meets the beam switching time requirement. Then, based on the judgment result of at least one pairwise combination, the terminal can determine the PDCCH listening time of at least one target CORESET among the PDCCH listening times of the at least two CORESETs.

[0098] It should be noted that the above examples are merely illustrative of the embodiments of this application and are not intended to limit the embodiments of this application.

[0099] Optionally, the PDCCH listening time for at least two CORESETs can be two or more CORESETs' PDCCH listening times. For example, it can be two CORESETs' PDCCH listening times, three CORESETs' PDCCH listening times, or five CORESETs' PDCCH listening times, without any limitation.

[0100] Understandably, the threshold value is used to characterize the maximum time required for the terminal to perform beam switching. If the time interval between the PDCCH listening times of any two target CORESETs in different beam directions is greater than or equal to the threshold value, it can be guaranteed that the time domain resource interval between any two target CORESETs in different beam directions is greater than the beam switching time.

[0101] Step 102: Detect the PDCCH when listening to the PDCCH of at least one target CORESET;

[0102] Among them, during the PDCCH listening time of at least one target CORESET, the time interval between the PDCCH listening times of any two target CORESETs corresponding to different beam directions is greater than or equal to a threshold value, which is used to characterize the maximum duration required for the terminal to perform beam switching.

[0103] Specifically, after determining the PDCCH listening time of at least one target CORESET, the terminal can detect the PDCCH in the beam direction corresponding to the PDCCH listening time of at least one target CORESET.

[0104] For example, at least one target CORESET may include CORESET 1, CORESET 2 and CORESET 3. The terminal may detect the PDCCH in the beam direction corresponding to CORESET 1 when listening to the PDCCH in CORESET 1, detect the PDCCH in the beam direction corresponding to CORESET 2 when listening to the PDCCH in CORESET 2, and detect the PDCCH in the beam direction corresponding to CORESET 3 when listening to the PDCCH in CORESET 3.

[0105] For example, at least one target CORESET may include CORESET 4, CORESET 5 and CORESET 6, wherein, according to the time order of PDCCH listening time, the PDCCH listening time of CORESET 4 is ranked first, the PDCCH listening time of CORESET 5 is ranked second, and the PDCCH listening time of CORESET 6 is ranked third, and the beam direction corresponding to each CORESET is different from each other.

[0106] The terminal can detect the PDCCH in the beam direction corresponding to CORESET 4 when listening to the PDCCH in CORESET 4, and then switch to the beam direction corresponding to CORESET 5, and then detect the PDCCH in the beam direction corresponding to CORESET 5 when listening to the PDCCH in CORESET 5, and then switch to the beam direction corresponding to CORESET 6, and then detect the PDCCH in the beam direction corresponding to CORESET 6 when listening to the PDCCH in CORESET 6.

[0107] It should be noted that the above examples are merely illustrative of the embodiments of this application and are not intended to limit the embodiments of this application.

[0108] It is understandable that, since the time interval between the PDCCH listening times of any two target CORESETs corresponding to different beam directions is greater than or equal to the threshold value, it can be guaranteed that PDCCH is detected in the beam direction corresponding to the PDCCH listening time of at least one target CORESET.

[0109] The PDCCH detection method provided in this application determines at least one target CORESET's PDCCH listening time among at least two CORESET's PDCCH listening times, such that the time interval between any two target CORESET's PDCCH listening times corresponding to different beam directions is greater than or equal to a threshold value. This allows the terminal to detect PDCCH in the beam directions corresponding to at least one target CORESET's PDCCH listening time. Consequently, when configuring CORESET resources, network-side devices do not need to ensure that the time-domain resource interval between two CORESETs with different beams is greater than the beam switching time, thus improving the flexibility of resource configuration and increasing resource utilization.

[0110] Optionally, among the physical downlink control channel (PDCCH) listening times of at least two control resource sets (CORESETs), the PDCCH listening time of at least one target CORESET is determined, including:

[0111] Determine the target ordering for at least two CORESETs;

[0112] Based on the target ordering corresponding to at least two CORESETs, determine the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two CORESETs.

[0113] Specifically, the terminal can sort at least two CORESETs, thereby obtaining the target sorting corresponding to at least two CORESETs, and then, based on the target sorting, determine the PDCCH listening timing of at least two CORESETs, and determine the PDCCH listening timing of at least one target CORESET among the PDCCH listening timings of at least two CORESETs.

[0114] For example, at least two CORESETs may include CORESET 1, CORESET 2, and CORESET 3. The terminal may sort the at least two CORESETs based on certain rules (such as time order or priority sorting). For example, the determined target order may be that CORESET 1 is in the first position, CORESET 2 is in the second position, and CORESET 3 is in the third position.

[0115] The terminal can then sort the targets as described above and determine the PDCCH listening timing of at least two CORESETs. Among the PDCCH listening timings of CORESET 1, CORESET 2, and CORESET 3, at least one target CORESET's PDCCH listening timing can be determined. For example, at least one target CORESET's PDCCH listening timing can be the PDCCH listening timings of CORESET 1 and CORESET 3.

[0116] Therefore, the terminal can detect the PDCCH in the beam direction corresponding to CORESET 1 when listening to the PDCCH in CORESET 1, and detect the PDCCH in the beam direction corresponding to CORESET 3 when listening to the PDCCH in CORESET 3.

[0117] It should be noted that the above examples are merely illustrative of the embodiments of this application and are not intended to limit the embodiments of this application.

[0118] Therefore, the terminal can determine the PDCCH listening time of at least two CORESETs according to the target order, and determine the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two CORESETs.

[0119] Optionally, determine the target ordering corresponding to at least two CORESETs, including at least one of the following:

[0120] Based on the time sequence of the PDCCH listening times corresponding to at least two CORESETs, determine the first target order corresponding to at least two CORESETs; or

[0121] Based on the priority sorting corresponding to at least two CORESETs, determine the second target sorting corresponding to at least two CORESETs.

[0122] Specifically, the terminal can sort at least two CORESETs according to the time order of the PDCCH listening times corresponding to at least two CORESETs respectively, thereby obtaining the target sorting corresponding to at least two CORESETs, and then judging the PDCCH listening times of at least two CORESETs based on the target sorting, and determining the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two CORESETs.

[0123] Specifically, the terminal can sort at least two CORESETs according to their priority, thereby obtaining the target sorting of at least two CORESETs. Based on the target sorting, the terminal can determine the PDCCH listening timing of at least two CORESETs and identify the PDCCH listening timing of at least one target CORESET among the PDCCH listening timings of at least two CORESETs.

[0124] For example, at least two CORESETs may include CORESET 1, CORESET 2, and CORESET 3. The terminal may sort at least two CORESETs based on the time order of the PDCCH listening times corresponding to the at least two CORESETs respectively. For example, the PDCCH listening time corresponding to CORESET 1 is the earliest and the PDCCH listening time corresponding to CORESET 3 is the latest. For example, the determined target order may be that CORESET 1 is ranked first, CORESET 2 is ranked second, and CORESET 3 is ranked third.

[0125] For example, at least two CORESETs may include CORESET 4, CORESET 5, and CORESET 6. The terminal may sort the at least two CORESETs based on their respective priorities, such as CORESET 4 having the highest priority, CORESET 5 having the second highest priority, and CORESET 6 having the lowest priority. For example, the determined target order could be CORESET 4 in the first position, CORESET 5 in the second position, and CORESET 6 in the third position.

[0126] Therefore, the terminal can determine the target order corresponding to at least two CORESETs in a variety of ways. The target order can be a first target order or a second target order. Then, based on the first target order or the second target order, the terminal can determine the PDCCH listening time of at least one target CORESET in the PDCCH listening time of at least two CORESETs.

[0127] Optionally, based on the target ordering corresponding to at least two CORESETs, the PDCCH listening time for at least one target CORESET is determined among the PDCCH listening times of at least two CORESETs, including:

[0128] Based on the first target sorting, determine whether to delete the first CORESET or the second CORESET from the set to be detected, until the time interval between the PDCCH listening times of any two CORESETs corresponding to different beam directions in the set to be detected is greater than or equal to the threshold value. Before determining whether to delete the first CORESET or the second CORESET from the set to be detected, the set to be detected includes at least two CORESETs.

[0129] The PDCCH listening time of the CORESET in the set to be detected is taken as the PDCCH listening time of at least one target CORESET;

[0130] Here, the first CORESET is the CORESET in the target time set that has not yet been judged together with all eleventh CORESETs. The eleventh CORESET is any CORESET that ranks after the first CORESET in the first target sorting among all CORESETs included in the target set except the first CORESET. The second CORESET is the CORESET that is closest to the first CORESET among all eleventh CORESETs at the target time. The target time is the time when it is determined whether to delete the first CORESET or the second CORESET from the target set.

[0131] Specifically, after determining the first target order, the terminal can add at least two CORESETs to the detection set to obtain the initial detection set. Then, based on the first target order, it can determine whether to delete the first CORESET or the second CORESET from the detection set until the time interval between the PDCCH listening times of any two CORESETs in different beam directions in the detection set is greater than or equal to the threshold value, that is, the time domain resource interval between any two target CORESETs in different beam directions in the detection set is greater than the beam switching time.

[0132] Specifically, after performing the above judgment based on the first target sorting, the terminal can take the CORESET in the detection set as at least one target CORESET, that is, it can take the PDCCH listening time of the CORESET in the detection set as the PDCCH listening time of at least one target CORESET.

[0133] Optionally, the first CORESET can be a CORESET in the target time set that has not yet been judged with the eleventh CORESET. The eleventh CORESET is any CORESET that ranks after the first CORESET in the first target sorting among all CORESETs included in the target set except the first CORESET. The target time can be the time when it is determined whether to delete the first CORESET or the second CORESET from the target set.

[0134] Optionally, the second CORESET can be the CORESET that is closest to the first CORESET among all the eleventh CORESETs at the target time.

[0135] For example, the first target order corresponding to CORESET in a certain time slot Slot0 can be CORESET1, CORESET2, CORESET3, CORESET4, and CORESET5 in that order, with CORESET1 being the first and CORESET5 being the last.

[0136] At target time A, if CORESET 1 has been removed from the set to be detected, and CORESET 2 has not yet been compared with the CORESETs that follow it, then the first CORESET can be CORESET 2; the eleventh CORESET can be any one of CORESET 3, CORESET 4 or CORESET 5. Since CORESET 3 is the CORESET closest to CORESET 2 among all eleventh CORESETs, the second CORESET can be CORESET 3.

[0137] At target time A, the terminal can determine whether to remove CORESET 2 or CORESET 3 from the set to be detected.

[0138] Therefore, the terminal can determine whether to remove the first or second CORESET from the detection set based on the first target sorting, so that the time interval between the PDCCH listening times of any two CORESETs corresponding to different beam directions in the finally determined detection set is greater than or equal to a threshold value. Then, based on the PDCCH listening times of the CORESETs in the detection set as the PDCCH listening times of at least one target CORESET, the terminal can detect PDCCH in the beam directions corresponding to the PDCCH listening times of at least one target CORESET.

[0139] Optionally, determining whether to remove the first CORESET or the second CORESET from the set to be detected includes:

[0140] If the beam direction corresponding to the first CORESET is different from that corresponding to the second CORESET, and the time interval between the PDCCH listening timing of the first CORESET and the PDCCH listening timing of the second CORESET is less than a threshold value, then the CORESET with lower priority in the first CORESET and the second CORESET will be removed from the set to be detected.

[0141] Specifically, in the operation of determining whether to delete the first CORESET or the second CORESET from the set to be detected, the terminal can determine whether the beam direction corresponding to the first CORESET and the beam direction corresponding to the second CORESET are the same, and determine whether the time interval between the PDCCH listening time of the first CORESET and the PDCCH listening time of the second CORESET is less than a threshold value.

[0142] Specifically, if it is determined that the beam direction corresponding to the first CORESET is different from that corresponding to the second CORESET, and the time interval between the PDCCH listening timing of the first CORESET and the PDCCH listening timing of the second CORESET is less than a threshold value, then the CORESET with lower priority in the first CORESET and the second CORESET can be deleted from the set to be detected.

[0143] Optionally, the terminal can first determine whether the beam direction corresponding to the first CORESET is the same as that corresponding to the second CORESET. If it is determined that the beam direction corresponding to the first CORESET is different from that corresponding to the second CORESET, then it can continue to determine whether the time interval between the PDCCH listening timing of the first CORESET and the PDCCH listening timing of the second CORESET is less than a threshold value. If the time interval between the PDCCH listening timing of the first CORESET and the PDCCH listening timing of the second CORESET is less than the threshold value, then the CORESET with lower priority in the first CORESET and the second CORESET can be deleted from the set to be detected.

[0144] Optionally, the terminal can first determine whether the time interval between the PDCCH listening timing of the first CORESET and the PDCCH listening timing of the second CORESET is less than a threshold value. If the time interval between the PDCCH listening timing of the first CORESET and the PDCCH listening timing of the second CORESET is less than the threshold value, then it can continue to determine whether the beam direction corresponding to the first CORESET and the beam direction corresponding to the second CORESET are the same. If it is determined that the beam direction corresponding to the first CORESET and the beam direction corresponding to the second CORESET are different, then the CORESET with lower priority in the first CORESET and the second CORESET can be deleted from the set to be detected.

[0145] Therefore, if the beam direction corresponding to the first CORESET is different from that corresponding to the second CORESET, and the time interval between the PDCCH listening time of the first CORESET and the PDCCH listening time of the second CORESET is less than a threshold value, the terminal can delete the lower priority CORESET from the set to be detected.

[0146] Optionally, based on the target ordering corresponding to at least two CORESETs, the PDCCH listening time for at least one target CORESET is determined among the PDCCH listening times of at least two CORESETs, including:

[0147] Based on the second target sorting, it is determined whether to add the third CORESET to the detection set, so that after adding the third CORESET to the detection set, the time interval between the PDCCH listening times of any two CORESETs corresponding to different beam directions in the detection set is greater than or equal to a threshold value; before determining whether to add the third CORESET to the detection set, the detection set includes at least the highest priority item among the two CORESETs;

[0148] The PDCCH listening time of the CORESET in the set to be detected is taken as the PDCCH listening time of at least one target CORESET;

[0149] The third CORESET is the highest-ranked CORESET in the second target sorting that has not yet been determined to be added to the detection set at the target time. The target time is the time when it is determined whether to add the third CORESET to the detection set.

[0150] Specifically, after determining the second target order, the terminal can add the highest priority item among at least two CORESETs to the detection set to obtain an initial detection set. Then, based on the second target order, it can determine whether to add a third CORESET to the detection set, so that after adding the third CORESET to the detection set, the time interval between the PDCCH listening times of any two CORESETs corresponding to different beam directions in the detection set is greater than or equal to a threshold value. That is, the time domain resource interval between any two target CORESETs in different beam directions in the detection set is greater than the beam switching time.

[0151] Specifically, after performing the above judgment based on the second target sorting, the terminal can take the CORESET in the detection set as at least one target CORESET, that is, it can take the PDCCH listening time of the CORESET in the detection set as the PDCCH listening time of at least one target CORESET.

[0152] For example, the second target order corresponding to CORESET in a certain time slot Slot0 can be CORESET1, CORESET2, CORESET3, CORESET4, and CORESET5 in that order, with CORESET1 being the first and CORESET5 being the last.

[0153] After determining the second target order, the terminal can add the highest priority item in Slot0, namely CORESET 1, to the detection set to obtain the initial detection set;

[0154] At target time B, if CORESET 2 has been determined to be added to the set to be detected, and CORESET 3 has not yet been determined to be added to the set to be detected, then CORESET 3 is the CORESET that is ranked first among the CORESETs that have not yet been determined to be added to the set to be detected at target time B in the second target sorting. Therefore, at target time B, the third CORESET can be CORESET 3.

[0155] At target time B, the terminal can determine whether to add CORESET 3 to the CORESET of the set to be detected.

[0156] Therefore, the terminal can determine whether to add the third CORESET to the detection set based on the second target sorting, so that the time interval between the PDCCH listening times of any two CORESETs corresponding to different beam directions in the finally determined detection set is greater than or equal to a threshold value. Then, based on the PDCCH listening times of the CORESETs in the detection set as the PDCCH listening times of at least one target CORESET, the terminal can detect PDCCH in the beam directions corresponding to the PDCCH listening times of at least one target CORESET.

[0157] Optionally, determining whether to add the third CORESET to the set to be detected includes:

[0158] If the time interval between the PDCCH listening time of each CORESET in the detection set and the PDCCH listening time of the third CORESET is greater than or equal to a threshold value, the third identifier is added to the detection set; or,

[0159] If there is at least one fourth CORESET in the set to be detected, and if the beam direction corresponding to each fourth CORESET is the same as the beam direction corresponding to the third CORESET, then the third CORESET is added to the set to be detected. Here, the fourth CORESET is a CORESET whose time interval between the PDCCH listening time of the third CORESET is less than a threshold value.

[0160] Specifically, in the process of determining whether to add the third CORESET to the set to be detected, the terminal can determine whether the time interval between the PDCCH listening time of each CORESET in the set to be detected and the PDCCH listening time of the third CORESET is greater than or equal to a threshold value. If it is determined that the time interval between the PDCCH listening time of each CORESET in the set to be detected and the PDCCH listening time of the third CORESET is greater than or equal to the threshold value, then the third CORESET can be added to the set to be detected.

[0161] Specifically, in the operation of determining whether to add the third CORESET to the set to be detected, the terminal can determine whether the beam direction corresponding to each fourth CORESET is the same as the beam direction corresponding to the third CORESET if there is at least one fourth CORESET in the set to be detected. If it is determined that the beam direction corresponding to each fourth CORESET is the same as the beam direction corresponding to the third CORESET, then the third CORESET can be added to the set to be detected.

[0162] The fourth CORESET can be a CORESET whose time interval between the PDCCH listening time of the third CORESET is less than a threshold value.

[0163] Therefore, by determining whether to add the third CORESET to the set to be detected, the terminal can ensure that after adding the third CORESET to the set to be detected, the time interval between the PDCCH listening times of any two CORESETs corresponding to different beam directions in the set to be detected is greater than or equal to the threshold value.

[0164] Optionally, before determining the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two control resource sets CORESETs, the method further includes:

[0165] Determine the target duration required for the terminal to perform beam switching;

[0166] Determine the threshold value based on the target duration;

[0167] Among them, the threshold value is greater than or equal to the target duration, and the threshold value is the number of symbols or the time value.

[0168] Specifically, the terminal can determine the target duration required for itself to perform beam switching, and then, based on the target duration, can determine a threshold value so that the threshold value is greater than or equal to the target duration.

[0169] Optionally, the terminal can determine the target duration required for itself to perform beam switching, and then, based on the target duration, determine the number of symbols so that the time length corresponding to the number of symbols is greater than or equal to the target duration.

[0170] Optionally, the terminal can determine the target duration required for itself to perform beam switching, and then, based on the target duration, can determine a time value so that the time value is greater than or equal to the target duration.

[0171] Therefore, by determining the target duration required for the terminal to perform beam switching, the threshold value can be used to characterize the maximum duration required for the terminal to perform beam switching.

[0172] Optionally, when the threshold value is the number of symbols, the threshold value is determined based on the target duration, including:

[0173] When at least two CORESETs correspond to at least two carrier units, the carrier with the smallest subcarrier spacing among the at least two carrier units is determined as the target carrier;

[0174] The number of symbols is determined based on the target carrier and the target duration.

[0175] Specifically, when the threshold value is the number of symbols, if at least two CORESETs correspond to at least two component carriers (CCs), the terminal can determine the one with the smallest subcarrier spacing among the at least two carriers as the target carrier, and then determine the number of symbols based on the target carrier and the target duration.

[0176] Therefore, the terminal can determine the target duration required for itself to perform beam switching, and then, based on the target carrier and the target duration, it can determine the number of symbols, such that the time length corresponding to the number of symbols is greater than or equal to the target duration.

[0177] Optionally, after determining the threshold value based on the target duration, the method further includes:

[0178] Send threshold values ​​to network-side devices.

[0179] Specifically, after determining the threshold value, the terminal can report the threshold value to the network-side device so that the network-side device can know the maximum time required for the terminal to perform beam switching.

[0180] Understandably, once the network-side device learns the maximum time required for the terminal to perform beam switching, it can adjust the PDCCH listening timing of subsequent CORESETs and / or adjust the beam direction of subsequent CORESETs based on this information.

[0181] Optionally, the beam direction corresponding to CORESET is determined based on the transmission configuration indication status associated with CORESET.

[0182] Optionally, the terminal can determine the beam direction corresponding to the CORESET based on the TCI state associated with the CORESET.

[0183] Optionally, the time interval between the PDCCH listening timing of the fifth CORESET and the PDCCH listening timing of the sixth CORESET in at least two CORESETs is determined based on the difference between the time domain position of the end symbol of the fifth CORESET and the time domain position of the start symbol of the sixth CORESET.

[0184] The fifth CORESET and the sixth CORESET are any two CORESETs out of at least two CORESETs; the fifth CORESET is the term that appears earlier in the time domain between the fifth CORESET and the sixth CORESET, and the sixth CORESET is the term that appears later in the time domain between the fifth CORESET and the sixth CORESET.

[0185] Specifically, the terminal can determine the difference between the time domain position of the end symbol of the fifth CORESET and the time domain position of the start symbol of the sixth CORESET, and then determine the time interval between the PDCCH listening timing of the fifth CORESET and the PDCCH listening timing of the sixth CORESET based on the difference.

[0186] It is understandable that the fifth CORESET and the sixth CORESET are any two CORESETs among at least two CORESETs. The fifth CORESET is the one that appears earlier in the time domain among the fifth CORESET and the sixth CORESET, and the sixth CORESET is the one that appears later in the time domain among the fifth CORESET and the sixth CORESET. That is, the time domain position of the start symbol of the fifth CORESET is before the time domain position of the start symbol of the sixth CORESET.

[0187] Therefore, the terminal can determine the time interval between the PDCCH listening timing of the fifth CORESET and the PDCCH listening timing of the sixth CORESET by the difference between the time domain position of the end symbol of the fifth CORESET and the time domain position of the start symbol of the sixth CORESET.

[0188] Optionally, before determining the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two control resource sets CORESETs, the method further includes:

[0189] Determine the priority order of at least two CORESETs based on one or more of the search space type, cell index, and search space index corresponding to each of the at least two CORESETs.

[0190] Optionally, the terminal can determine the priority order of at least two CORESETs based on the search space types corresponding to at least two CORESETs respectively.

[0191] Optionally, the terminal may determine the priority order of at least two CORESETs based on the cell indexes corresponding to at least two CORESETs respectively.

[0192] Optionally, the terminal may determine the priority order of at least two CORESETs based on the search space indexes corresponding to at least two CORESETs respectively.

[0193] Optionally, the terminal can determine the priority order of at least two CORESETs based on the search space type and search space index corresponding to at least two CORESETs respectively.

[0194] Optionally, the terminal can determine the priority order of at least two CORESETs based on the search space type and cell index corresponding to at least two CORESETs respectively.

[0195] Optionally, the terminal can determine the priority order of at least two CORESETs based on the cell index and search space index corresponding to at least two CORESETs respectively.

[0196] Optionally, the terminal can determine the priority order of at least two CORESETs based on the search space type, cell index, and search space index corresponding to at least two CORESETs respectively.

[0197] Therefore, the terminal can determine the priority order of at least two CORESETs based on one or more configuration information corresponding to each of the at least two CORESETs.

[0198] Optionally, based on one or more of the search space type, cell index, and search space index corresponding to at least two CORESETs, the priority order corresponding to at least two CORESETs is determined, including:

[0199] Based on the search space types corresponding to at least two CORESETs, obtain the first priority sort for at least two CORESETs;

[0200] If there are multiple CORESETs with the same priority in the first priority sort, sort the multiple CORESETs with the same priority in the first priority sort based on the cell index corresponding to at least two CORESETs respectively, and obtain the second priority sort corresponding to at least two CORESETs.

[0201] If there are multiple CORESETs with the same priority in the second priority sort, sort the multiple CORESETs with the same priority in the second priority sort based on the search space index corresponding to at least two CORESETs respectively, and obtain the third priority sort corresponding to at least two CORESETs;

[0202] Priority sorting is determined based on first priority sorting, second priority sorting, and third priority sorting.

[0203] Optionally, the terminal can obtain the first priority sorting corresponding to at least two CORESETs based on the search space types corresponding to at least two CORESETs respectively, and then determine the priority sorting based on the first priority sorting.

[0204] Optionally, the terminal can obtain the first priority sorting corresponding to at least two CORESETs based on the search space types corresponding to at least two CORESETs respectively, and then sort multiple CORESETs with the same priority in the first priority sorting based on the cell index corresponding to at least two CORESETs respectively, obtain the second priority sorting corresponding to at least two CORESETs, and then determine the priority sorting based on the second priority sorting.

[0205] Optionally, the terminal can obtain the first priority sorting corresponding to at least two CORESETs based on the search space types corresponding to at least two CORESETs respectively;

[0206] Furthermore, based on the cell indexes corresponding to at least two CORESETs, multiple CORESETs with the same priority in the first priority sort can be sorted to obtain the second priority sort corresponding to at least two CORESETs.

[0207] Then, based on the search space index corresponding to at least two CORESETs respectively, multiple CORESETs with the same priority in the second priority sort can be sorted to obtain the third priority sort corresponding to at least two CORESETs, and then the priority sort can be determined based on the third priority sort.

[0208] Therefore, the terminal can determine the priority order based on the first priority order, the second priority order, and the third priority order.

[0209] Optionally, the search space type includes public search space and user-specific search space. In the first priority ranking, CORESET with public search space type is ranked before CORESET with user-specific search space type.

[0210] Optionally, the terminal can sort at least two CORESETs based on the sorting rule that CORESETs with a search space type of public search space are ranked before CORESETs with a search space type of user-specific search space, and obtain the first priority sorting corresponding to at least two CORESETs.

[0211] Optionally, in the second priority sorting, the seventh CORESET is ranked before the eighth CORESET. The seventh CORESET and the eighth CORESET are any two CORESETs among the multiple CORESETs with the same priority in the first priority sorting, and the cell index corresponding to the seventh CORESET is less than the cell index corresponding to the eighth CORESET.

[0212] Optionally, the terminal can sort multiple CORESETs with the same priority in the first priority sorting based on the sorting rule that the smaller the cell index, the higher the priority. This will obtain the second priority sorting corresponding to at least two CORESETs, such that the seventh CORESET is ranked before the eighth CORESET in the second priority sorting.

[0213] Optionally, in the third priority sorting, the ninth CORESET is ranked before the tenth CORESET. The ninth CORESET and the tenth CORESET are any two CORESETs among the multiple CORESETs with the same priority in the second priority sorting. The search space index corresponding to the ninth CORESET is less than the search space index corresponding to the tenth CORESET.

[0214] Optionally, the terminal can sort multiple CORESETs with the same priority in the second priority sort based on the sorting rule that the smaller the search space index, the higher the priority. This will obtain the third priority sort corresponding to at least two CORESETs, such that the ninth CORESET is ranked before the tenth CORESET in the third priority sort.

[0215] Optionally, before determining the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two control resource sets CORESETs, the method further includes:

[0216] Based on the time-domain position of the first symbol corresponding to at least two CORESETs, determine the priority order corresponding to at least two CORESETs;

[0217] Among them, for any two items in at least two CORESETs, the item with the earlier time domain position of the first symbol has a higher priority than the item with the later time domain position of the first symbol;

[0218] The first symbol is either the start symbol or the end symbol of a CORESET.

[0219] Optionally, the terminal can sort at least two CORESETs based on a sorting rule that prioritizes earlier-positioned symbols in the time domain, and obtain the priority sorting of at least two CORESETs.

[0220] Optionally, the terminal can sort at least two CORESETs based on a sorting rule that prioritizes earlier start symbols in the time domain, and obtain the priority sorting for at least two CORESETs.

[0221] Optionally, the terminal can sort at least two CORESETs based on a sorting rule that prioritizes the earlier the end symbol appears in the time domain, and obtain the priority sorting corresponding to at least two CORESETs.

[0222] Optionally, at least two CORESETs may have the first N symbols of the target timeslot available in the time domain, where N is a positive integer, N is determined by the protocol or configured by the network-side device, 1≤N≤M, and M is the total number of symbols in the target timeslot, where M is a positive integer.

[0223] Optionally, at least two CORESETs can agree by protocol to have the first N symbols of the target time slot available in the time domain, 1≤N≤M, where M is the total number of symbols in the target time slot, and N and M are positive integers.

[0224] Optionally, at least two CORESETs can be configured in the network-side device to have the first N symbols of the target time slot available in the time domain, 1≤N≤M, where M is the total number of symbols in the target time slot, and N is a positive integer and M is a positive integer.

[0225] The PDCCH detection method provided in this application determines at least one target CORESET's PDCCH listening time among at least two CORESET's PDCCH listening times, such that the time interval between any two target CORESET's PDCCH listening times corresponding to different beam directions is greater than or equal to a threshold value. This allows the terminal to detect PDCCH in the beam directions corresponding to at least one target CORESET's PDCCH listening time. Consequently, when configuring CORESET resources, network-side devices do not need to ensure that the time-domain resource interval between two CORESETs with different beams is greater than the beam switching time, thus improving the flexibility of resource configuration and increasing resource utilization.

[0226] In one embodiment, Figure 2 This is one of the schematic diagrams of single-carrier PDCCH monitoring timing provided in the embodiments of this application. Figure 2 This is an optional example of this application, but not intended to limit it; Figure 2As shown in Table 1, the PDCCH listening timing for at least two control resource sets (CORESET) on a single carrier can determine the priority of each CORESET. The smaller the priority level value, the higher the priority. The Transmission Configuration Indicator (TCI) status of each CORESET can be determined by the Reference Signal (RS) indicated by Quasi Co-Location (QCL) type D.

[0229] Optionally, the threshold value can be the length of a symbol.

[0230] The process of determining the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two CORESETs may include steps 201 to 202:

[0231] Step 201: For each slot, at least two CORESETs are configured, sorted according to their start time. This allows obtaining the first target sorting corresponding to the CORESET in slot0 and the first target sorting corresponding to the CORESET in slot1, where:

[0232] The first target order corresponding to CORESET in Slot0 can be CORESET 1, CORESET 2, CORESET 3, CORESET 4, and CORESET 5 in that order, with CORESET 1 being the first and CORESET 5 being the last.

[0233] The first target order corresponding to CORESET in Slot1 can be CORESET 1, CORESET 4, and CORESET 5 in that order, with CORESET 1 being the first and CORESET 5 being the last.

[0234] Step 202: Determine whether beam overlap exists according to the first target sorting and perform beam overlap processing;

[0235] Optionally, the criterion for beam overlap is whether the interval between the last symbol of the previous PDCCH listening time and the first symbol of the next PDCCH listening time is less than a threshold requirement. If it is less than the threshold requirement, beam overlap exists.

[0236] Optionally, the beam overlap handling method can be as follows: if the PDCCH listening times of two CORESETs overlap, and the TCI states of the two CORESETs are inconsistent, then the CORESET with lower priority among the two CORESETs is deleted from the set of CORESETs to be detected; if the PDCCH listening times of two CORESETs overlap, and the TCI states of the two CORESETs are consistent, then the two CORESETs are retained in the set of CORESETs to be detected.

[0237] For example, the CORESETs in Slot0 can be sorted according to the first target corresponding to the CORESET in Slot0. The CORESETs in Slot0 can be checked pairwise to see if there is beam overlap, and beam overlap processing can be performed. Then, the order of deleting CORESETs from the set of CORESETs to be detected corresponding to Slot0 can be determined. From front to back, they can be CORESET 1, CORESET 2, CORESET 4, and CORESET 5. CORESET 1 is deleted first, and CORESET 5 is deleted last.

[0238] For example, the CORESETs in Slot1 can be sorted according to the first target corresponding to the CORESET in Slot1, and the pairwise CORESETs in Slot1 can be checked for beam overlap and beam overlap processing can be performed; thus, it can be determined that CORESET 5 can be deleted from the set of CORESETs to be detected.

[0239] Optionally, with a threshold value of one symbol length, the final set of CORESETs to be detected, 1, can be determined, as shown in Table 2.

[0242] Optionally, Figure 3 This is the second schematic diagram of single-carrier PDCCH listening timing provided in the embodiments of this application, as shown below. Figure 3 As shown, with a threshold value of one symbol length, the final set of CORESETs to be detected can be determined.

[0243] Optionally, Figure 4 This is one of the schematic diagrams of multi-carrier PDCCH monitoring timing provided in the embodiments of this application. Figure 4 This is an optional example of this application, but not intended to limit it; Figure 4As shown in Table 3, the PDCCH listening timing for at least two control resource sets (CORESET) of a multi-carrier system can be determined, and the priority of each CORESET can be determined as shown in Table 3. The smaller the priority level value, the higher the priority. The TCI status of each CORESET can be determined by the RS indicated by QCL typeD.

[0246] Optionally, such as Figure 4 As shown, the threshold value can be the length of one symbol of CC1 (CC1 has a smaller SCS, so the threshold value is defined based on the number of symbols of CC1, which can be converted into the length of two symbols of CC2).

[0247] The process of determining the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two CORESETs may include steps 401 to 402:

[0248] Step 401: For at least two CORESETs configured in slot0, sort them according to their start time, and sort all CCs together. This allows us to obtain the first target sorting corresponding to the CORESETs in slot0, where:

[0249] The first target order corresponding to CORESET in Slot0 can be CORESET 1, CORESET 6, CORESET 2, CORESET 7, CORESET 3, CORESET 4, and CORESET 5, with CORESET 1 being the first and CORESET 5 being the last.

[0250] Step 402: Determine whether beam overlap exists according to the first target sorting and perform beam overlap processing;

[0251] Optionally, the criterion for beam overlap is whether the interval between the last symbol of the previous PDCCH listening time and the first symbol of the next PDCCH listening time is less than a threshold requirement. If it is less than the threshold requirement, beam overlap exists.

[0252] Optionally, the beam overlap handling method can be as follows: if the PDCCH listening times of two CORESETs overlap, and the TCI states of the two CORESETs are inconsistent, then the CORESET with lower priority among the two CORESETs is deleted from the set of CORESETs to be detected; if the PDCCH listening times of two CORESETs overlap, and the TCI states of the two CORESETs are consistent, then the two CORESETs are retained in the set of CORESETs to be detected.

[0253] For example, the CORESETs in Slot0 can be sorted according to the first target corresponding to the CORESET in Slot0. The CORESETs in Slot0 can be checked pairwise to see if there is beam overlap, and beam overlap processing can be performed. Then, the order of deleting CORESETs from the set of CORESETs to be detected can be determined. From front to back, they can be CORESET 1, CORESET 6, CORESET 7, CORESET 2, CORESET 4, CORESET 5. Among them, CORESET 1 is deleted first and CORESET 5 is deleted last.

[0254] Optionally, with a threshold value of one symbol length of CC1, the final set of CORESETs to be detected, 2, can be determined, as shown in Table 4.

[0257] Optionally, Figure 5 This is the second schematic diagram of the multi-carrier PDCCH listening timing provided in the embodiments of this application, as shown below. Figure 5 As shown, with a threshold value of one symbol length of CC1, the final set of CORESETs to be detected, 2, can be determined.

[0258] Figure 6 This is the third schematic diagram of the single-carrier PDCCH listening timing provided in the embodiments of this application. Figure 6 This is an optional example of this application, but not intended to limit it; Figure 6 As shown in Table 5, the PDCCH listening timing for at least two control resource sets (CORESET) on a single carrier can be determined, and the priority of each CORESET can be determined as shown in Table 5. The smaller the priority level value, the higher the priority. The TCI status of each CORESET can be determined by the RS indicated by QCL typeD.

[0261] Optionally, the threshold value can be the length of a symbol.

[0262] The process of determining the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two CORESETs may include steps 601 to 603:

[0263] Step 601: For each slot, at least two CORESETs are configured, sorted according to priority. This allows obtaining the second target sorting corresponding to the CORESET in slot 0 and the second target sorting corresponding to the CORESET in slot 1, where:

[0264] The second target order corresponding to CORESET in Slot0 can be CORESET 3, CORESET 2, CORESET 1, CORESET 4, and CORESET 5 in that order, with CORESET 3 first and CORESET 5 last.

[0265] The second target order corresponding to CORESET in Slot1 can be CORESET 1, CORESET 4, and CORESET 5 in that order, with CORESET 1 first and CORESET 5 last.

[0266] Step 602: Add the highest priority CORESET to the set of CORESETs to be detected, and record its corresponding QCL-type D;

[0267] For example, if the highest priority CORESET in Slot0 is CORESET3, then CORESET3 can be put into the set of CORESETs to be detected corresponding to Slot0, and the QCL-type D corresponding to CORESET3 can be recorded.

[0268] For example, if the highest priority CORESET in Slot1 is CORESET 1, then CORESET1 can be put into the set of CORESETs to be detected corresponding to Slot1, and the QCL-type D corresponding to CORESET1 can be recorded.

[0269] Step 603: Determine whether beam overlap exists according to the second target sorting and perform beam overlap processing;

[0270] Optionally, the criterion for beam overlap is whether the interval between the last symbol of the previous PDCCH listening time and the first symbol of the next PDCCH listening time is less than a threshold requirement. If it is less than the threshold requirement, beam overlap exists.

[0271] Optionally, at the target time, if the PDCCH listening time of each CORESET in the set of CORESETs to be detected corresponding to the Slot (e.g., Slot0 or Slot1) does not overlap with the PDCCH listening time of the third CORESET, that is, the time interval between the PDCCH listening time of each CORESET in the set of CORESETs to be detected corresponding to the Slot is greater than or equal to the threshold value, then the third CORESET can be added to the set of CORESETs to be detected corresponding to the Slot.

[0272] The third CORESET can be the CORESET ranked first in the second target sorting of the CORESET in the slot that has not yet been judged whether to be added to the CORESET set to be detected at the target time. The target time is the time when it is determined whether to add the third CORESET to the CORESET set to be detected corresponding to the slot.

[0273] Optionally, the beam overlap processing method may be as follows: if there is at least one fourth CORESET in the set of CORESETs to be detected corresponding to a Slot (e.g., Slot0 or Slot1), and if the TCI state corresponding to each fourth CORESET is consistent with the TCI state corresponding to the third CORESET, then the third CORESET is added to the set of CORESETs to be detected; wherein, the fourth CORESET is a CORESET that has beam overlap with the third CORESET.

[0274] For example, by performing steps 602 and 603 on the CORESET in Slot0, the order in which the CORESET is added to the set of CORESETs to be detected can be determined. From front to back, the order can be CORESET 3, CORESET 1, with CORESET 3 being added first and CORESET 1 being added last.

[0275] For example, by performing steps 602 and 603 on the CORESET in Slot1, the order in which the CORESET is added to the set of CORESETs to be detected can be determined. From front to back, the order can be CORESET 1, CORESET 4, with CORESET 1 added first and CORESET 4 added last.

[0276] Optionally, with a threshold value of one symbol length, the final set of CORESETs to be detected can be determined, as shown in Table 6.

[0279]

[0280] Optionally, Figure 7 This is the fourth schematic diagram of the single-carrier PDCCH listening timing provided in the embodiments of this application, as shown below. Figure 7 As shown, with a threshold value of one symbol length, the final set of CORESETs to be detected can be determined.

[0281] Figure 8 This is the third schematic diagram of the multi-carrier PDCCH listening timing provided in the embodiments of this application. Figure 8 This is an optional example of this application, but not intended to limit it; Figure 8 As shown in Table 7, the PDCCH listening timing for at least two control resource sets (CORESET) of a multi-carrier system can be determined, and the priority of each CORESET can be determined by the RS indicated by QCL typeD. The smaller the priority level value, the higher the priority.

[0284] Optionally, such as Figure 8 As shown, the threshold value can be the length of one symbol of CC1 (CC1 has a smaller SCS, so the threshold value is defined based on the number of symbols of CC1, which can be converted into the length of two symbols of CC2).

[0285] The process of determining the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two CORESETs may include steps 801-803:

[0286] Step 801: For at least two CORESETs configured in slot0, sort them according to priority, and sort all CCs together to obtain the second target sorting corresponding to the CORESETs in slot0, where:

[0287] The second target order corresponding to CORESET in Slot0 can be CORESET 3, CORESET 2, CORESET 1, CORESET 4, CORESET 5, CORESET 6, and CORESET 7, with CORESET 3 listed first and CORESET 7 listed last.

[0288] Step 802: Add the highest priority CORESET to the set of CORESETs to be detected, and record its corresponding QCL-type D;

[0289] For example, if the highest priority CORESET in Slot0 is CORESET3, then CORESET3 can be put into the set of CORESETs to be detected corresponding to Slot0, and the QCL-type D corresponding to CORESET3 can be recorded.

[0290] Step 803: Determine whether beam overlap exists according to the second target sorting and perform beam overlap processing;

[0291] Optionally, the criterion for beam overlap is whether the interval between the last symbol of the previous PDCCH listening time and the first symbol of the next PDCCH listening time is less than a threshold requirement. If it is less than the threshold requirement, beam overlap exists.

[0292] Optionally, at the target time, if the PDCCH listening time of each CORESET in the set of CORESETs to be detected corresponding to the Slot (e.g., Slot0) does not overlap with the PDCCH listening time of the third CORESET, that is, the time interval between the PDCCH listening time of each CORESET in the set of CORESETs to be detected corresponding to the Slot is greater than or equal to the threshold value, then the third CORESET can be added to the set of CORESETs to be detected corresponding to the Slot.

[0293] The third CORESET can be the CORESET ranked first in the second target sorting of the CORESET in the slot that has not yet been judged whether to be added to the CORESET set to be detected at the target time. The target time is the time when it is determined whether to add the third CORESET to the CORESET set to be detected corresponding to the slot.

[0294] Optionally, the beam overlap processing method may be as follows: if there is at least one fourth CORESET in the set of CORESETs to be detected corresponding to Slot (e.g., Slot0), and if the TCI state corresponding to each fourth CORESET is consistent with the TCI state corresponding to the third CORESET, then the third CORESET is added to the set of CORESETs to be detected; wherein, the fourth CORESET is a CORESET that has beam overlap with the third CORESET.

[0295] For example, by performing steps 802 and 803 on the CORESET in Slot0, the order in which the CORESET is added to the set of CORESETs to be detected corresponding to Slot0 can be determined. From front to back, the order can be CORESET 3, CORESET 1, and CORESET 6. CORESET 3 is added first, and CORESET 6 is added last.

[0296] Optionally, with a threshold value of one symbol length of CC1, the final set of CORESETs to be detected, 4, can be determined, as shown in Table 8.

[0297] Table 8 Final set of CORESETs to be detected 4

[0299] Optionally, Figure 9 This is the fourth schematic diagram of the multi-carrier PDCCH listening timing provided in the embodiments of this application, as shown below. Figure 9 As shown, with a threshold value of one symbol length of CC1, the final set of CORESETs to be detected can be determined.

[0300] The PDCCH detection method provided in this application determines at least one target CORESET's PDCCH listening time among at least two CORESET's PDCCH listening times, such that the time interval between any two target CORESET's PDCCH listening times corresponding to different beam directions is greater than or equal to a threshold value. This allows the terminal to detect PDCCH in the beam directions corresponding to at least one target CORESET's PDCCH listening time. Consequently, when configuring CORESET resources, network-side devices do not need to ensure that the time-domain resource interval between two CORESETs with different beams is greater than the beam switching time, thus improving the flexibility of resource configuration and increasing resource utilization.

[0301] The methods and apparatuses provided in the various embodiments of this application are based on the same concept. Since the methods and apparatuses solve problems in similar ways, the implementations of the apparatuses and methods can refer to each other, and repeated details will not be repeated.

[0302] Figure 10 This is a schematic diagram of the structure of a terminal provided in an embodiment of this application, such as... Figure 10 As shown, the terminal includes a memory 1020, a transceiver 1000, and a processor 1010, wherein:

[0303] The memory 1020 is used to store computer programs; the transceiver 1000 is used to send and receive data under the control of the processor 1010; the processor 1010 is used to read the computer program in the memory 1020 and perform the following operations:

[0304] Among the physical downlink control channel (PDCCH) listening opportunities of at least two control resource sets (CORESET), determine the PDCCH listening opportunity of at least one target CORESET;

[0305] Detect the PDCCH when listening to the PDCCH of at least one target CORESET;

[0306] Among them, during the PDCCH listening time of at least one target CORESET, the time interval between the PDCCH listening times of any two target CORESETs corresponding to different beam directions is greater than or equal to a threshold value, which is used to characterize the maximum duration required for the terminal to perform beam switching.

[0307] The terminal provided in this application determines at least one target core's PDCCH listening time among at least two cores' PDCCH listening times, such that the time interval between any two target cores' PDCCH listening times corresponding to different beam directions is greater than or equal to a threshold value. This allows the terminal to detect PDCCH in the beam directions corresponding to each of the at least one target core's PDCCH listening times. Consequently, when configuring core resources, the network-side device does not need to ensure that the time-domain resource interval between two cores with different beams is greater than the beam switching time, thus improving the flexibility of control resource configuration and increasing resource utilization.

[0308] Specifically, transceiver 1000 is used to receive and send data under the control of processor 1010.

[0309] Among them, Figure 10 In this context, the bus architecture can include any number of interconnected buses and bridges, specifically linking various circuits of one or more processors represented by processor 1010 and memory represented by memory 1020 together. The bus architecture can also link various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. The bus interface provides an interface. The transceiver 1000 can be multiple components, including transmitters and receivers, providing a unit for communicating with various other devices over a transmission medium, including wireless channels, wired channels, optical fibers, etc. For different user equipment, the user interface 1030 can also be an interface capable of connecting external or internal devices, including but not limited to keypads, displays, speakers, microphones, joysticks, etc.

[0310] The processor 1010 is responsible for managing the bus architecture and general processing, while the memory 1020 can store the data used by the processor 1010 when performing operations.

[0311] Optionally, the processor 1010 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a complex programmable logic device (CPLD), and the processor may also adopt a multi-core architecture.

[0312] The processor executes any of the methods provided in the embodiments of this application by calling a computer program stored in memory, according to the obtained executable instructions. The processor and memory may also be physically separated.

[0313] Optionally, among the physical downlink control channel (PDCCH) listening times of at least two control resource sets (CORESETs), the PDCCH listening time of at least one target CORESET is determined, including:

[0314] Determine the target ordering for at least two CORESETs;

[0315] Based on the target ordering corresponding to at least two CORESETs, determine the PDCCH listening time of at least one target CORESET among the PDCCH listening times of at least two CORESETs.

[0316] Optionally, determine the target ordering corresponding to at least two CORESETs, including at least one of the following:

[0317] Based on the time sequence of the PDCCH listening times corresponding to at least two CORESETs, determine the first target order corresponding to at least two CORESETs; or

[0318] Based on the priority sorting corresponding to at least two CORESETs, determine the second target sorting corresponding to at least two CORESETs.

[0319] Optionally, based on the target ordering corresponding to at least two CORESETs, the PDCCH listening time for at least one target CORESET is determined among the PDCCH listening times of at least two CORESETs, including:

[0320] Based on the first target sorting, determine whether to delete the first CORESET or the second CORESET from the set to be detected, until the time interval between the PDCCH listening times of any two CORESETs corresponding to different beam directions in the set to be detected is greater than or equal to the threshold value. Before determining whether to delete the first CORESET or the second CORESET from the set to be detected, the set to be detected includes at least two CORESETs.

[0321] The PDCCH listening time of the CORESET in the set to be detected is taken as the PDCCH listening time of at least one target CORESET;

[0322] Here, the first CORESET is the CORESET in the target time set that has not yet been judged together with all eleventh CORESETs. The eleventh CORESET is any CORESET that ranks after the first CORESET in the first target sorting among all CORESETs included in the target set except the first CORESET. The second CORESET is the CORESET that is closest to the first CORESET among all eleventh CORESETs at the target time. The target time is the time when it is determined whether to delete the first CORESET or the second CORESET from the target set.

[0323] Optionally, determining whether to remove the first CORESET or the second CORESET from the set to be detected includes:

[0324] If the beam direction corresponding to the first CORESET is different from that corresponding to the second CORESET, and the time interval between the PDCCH listening timing of the first CORESET and the PDCCH listening timing of the second CORESET is less than a threshold value, then the CORESET with lower priority in the first CORESET and the second CORESET will be removed from the set to be detected.

[0325] Optionally, based on the target ordering corresponding to at least two CORESETs, the PDCCH listening time for at least one target CORESET is determined among the PDCCH listening times of at least two CORESETs, including:

[0326] Based on the second target sorting, it is determined whether to add the third CORESET to the detection set, so that after adding the third CORESET to the detection set, the time interval between the PDCCH listening times of any two CORESETs corresponding to different beam directions in the detection set is greater than or equal to a threshold value; before determining whether to add the third CORESET to the detection set, the detection set includes at least the highest priority item among the two CORESETs;

[0327] The PDCCH listening time of the CORESET in the set to be detected is taken as the PDCCH listening time of at least one target CORESET;

[0328] The third CORESET is the highest-ranked CORESET in the second target sorting that has not yet been determined to be added to the detection set at the target time. The target time is the time when it is determined whether to add the third CORESET to the detection set.

[0329] Optionally, determining whether to add the third CORESET to the set to be detected includes:

[0330] If the time interval between the PDCCH listening time of each CORESET in the detection set and the PDCCH listening time of the third CORESET is greater than or equal to a threshold value, the third identifier is added to the detection set; or,

[0331] If there is at least one fourth CORESET in the set to be detected, and if the beam direction corresponding to each fourth CORESET is the same as the beam direction corresponding to the third CORESET, then the third CORESET is added to the set to be detected. Here, the fourth CORESET is a CORESET whose time interval between the PDCCH listening time of the third CORESET is less than a threshold value.

[0332] Optionally, before determining the PDCCH listening time for at least one target CORESET among the PDCCH listening times for at least two control resource sets CORESET, the operation further includes:

[0333] Determine the target duration required for the terminal to perform beam switching;

[0334] Determine the threshold value based on the target duration;

[0335] Among them, the threshold value is greater than or equal to the target duration, and the threshold value is the number of symbols or the time value.

[0336] Optionally, when the threshold value is the number of symbols, the threshold value is determined based on the target duration, including:

[0337] When at least two CORESETs correspond to at least two carrier units, the carrier with the smallest subcarrier spacing among the at least two carrier units is determined as the target carrier;

[0338] The number of symbols is determined based on the target carrier and the target duration.

[0339] Optionally, after determining the threshold value based on the target duration, the operation further includes:

[0340] Send threshold values ​​to network-side devices.

[0341] Optionally, the beam direction corresponding to CORESET is determined based on the transmission configuration indication status associated with CORESET.

[0342] Optionally, the time interval between the PDCCH listening timing of the fifth CORESET and the PDCCH listening timing of the sixth CORESET in at least two CORESETs is determined based on the difference between the time domain position of the end symbol of the fifth CORESET and the time domain position of the start symbol of the sixth CORESET.

[0343] The fifth CORESET and the sixth CORESET are any two CORESETs out of at least two CORESETs; the fifth CORESET is the term that appears earlier in the time domain between the fifth CORESET and the sixth CORESET, and the sixth CORESET is the term that appears later in the time domain between the fifth CORESET and the sixth CORESET.

[0344] Optionally, before determining the PDCCH listening time for at least one target CORESET among the PDCCH listening times for at least two control resource sets CORESET, the operation further includes:

[0345] Determine the priority order of at least two CORESETs based on one or more of the search space type, cell index, and search space index corresponding to each of the at least two CORESETs.

[0346] Optionally, based on one or more of the search space type, cell index, and search space index corresponding to at least two CORESETs, the priority order corresponding to at least two CORESETs is determined, including:

[0347] Based on the search space types corresponding to at least two CORESETs, obtain the first priority sort for at least two CORESETs;

[0348] If there are multiple CORESETs with the same priority in the first priority sort, sort the multiple CORESETs with the same priority in the first priority sort based on the cell index corresponding to at least two CORESETs respectively, and obtain the second priority sort corresponding to at least two CORESETs.

[0349] If there are multiple CORESETs with the same priority in the second priority sort, sort the multiple CORESETs with the same priority in the second priority sort based on the search space index corresponding to at least two CORESETs respectively, and obtain the third priority sort corresponding to at least two CORESETs;

[0350] Priority sorting is determined based on first priority sorting, second priority sorting, and third priority sorting.

[0351] Optionally, the search space type includes public search space and user-specific search space. In the first priority ranking, CORESET with public search space type is ranked before CORESET with user-specific search space type.

[0352] Optionally, in the second priority sorting, the seventh CORESET is ranked before the eighth CORESET.

[0356] Among them, for any two items in at least two CORESETs, the item with the earlier time domain position of the first symbol has a higher priority than the item with the later time domain position of the first symbol;

[0357] The first symbol is either the start symbol or the end symbol of a CORESET.

[0358] Optionally, at least two CORESETs may have the first N symbols of the target timeslot available in the time domain, where N is a positive integer, N is determined by the protocol or configured by the network-side device, 1≤N≤M, and M is the total number of symbols in the target timeslot, where M is a positive integer.

[0359] The terminal provided in this application determines at least one target core's PDCCH listening time among at least two cores' PDCCH listening times, such that the time interval between any two target cores' PDCCH listening times corresponding to different beam directions is greater than or equal to a threshold value. This allows the terminal to detect PDCCH in the beam directions corresponding to each of the at least one target core's PDCCH listening times. Consequently, when configuring core resources, the network-side device does not need to ensure that the time-domain resource interval between two cores with different beams is greater than the beam switching time, thus improving the flexibility of control resource configuration and increasing resource utilization.
