[0001] The present invention relates to the field of communication technology, and in particular to a channel monitoring and transmission method, device, terminal and network side equipment. Background Art

[0002] In related technologies, the Physical Downlink Control Channel (PDCCH) can be transmitted at different aggregation levels, including aggregation levels 1, 2, 4, 8, and 16.

[0036] The channel monitoring method provided in the embodiment of the present application is described in detail below with reference to specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0037] like Figure 2 As shown, an embodiment of the present application provides a channel monitoring method, which is applied to a terminal, and the method includes:

[0038] Step 201: monitoring a physical downlink control channel (PDCCH) in at least two PDCCH monitoring opportunities.

[0039] Each of the PDCCH monitoring opportunities corresponds to a portion of the control channel elements (CCEs) of the PDCCH, which means that each of the PDCCH monitoring opportunities transmits a portion of the CCEs of the PDCCH.

[0040] Here, each PDCCH monitoring opportunity corresponds to part of the CCEs of the PDCCH, and the CCEs corresponding to the at least two PDCCH monitoring opportunities are combined to form a complete PDCCH, or the number of CCEs corresponding to each of the PDCCH monitoring opportunities is less than the number of CCEs corresponding to the aggregation level of the PDCCH.

[0041] The aggregation level of the PDCCH is configured by the network device. Preferably, the aggregation level of the PDCCH is greater than or equal to a preset threshold, for example, the preset threshold is 16.

[0042] For example, the aggregation level of the above-mentioned PDCCH is L, that is, the PDCCH includes L CCEs, and each monitoring opportunity in the multiple PDCCH monitoring opportunities transmits part of the L CCEs. Figure 3 As shown, L CCEs are distributed in 2 listening opportunities, and each listening opportunity corresponds to L / 2 CCEs. That is, all the information of the PDCCH is transmitted through the CCEs in the two listening opportunities. Figure 4 As shown, L CCEs are transmitted in one PDCCH listening opportunity. That is, the L CCEs in one PDCCH listening opportunity transmit all the information of the PDCCH. Therefore, in the embodiment of the present application, each PDCCH listening opportunity corresponds to part of the CCEs of the PDCCH, so that the terminal can realize joint detection of the PDCCH based on multiple PDCCH listening opportunities. Optionally, the at least two PDCCH listening opportunities belong to the same control resource set CORESET or belong to different control resource sets;

[0043] Alternatively, at least two of the PDCCH monitoring opportunities belong to the same search space set (Search Space Set, SS Set) or belong to different search space sets.

[0044] In a case where the two PDCCH monitoring opportunities belong to different control resource sets, at least one of the following parameters of the two PDCCH monitoring opportunities is the same:

[0045] The size of the resource element group REG bundle (REG bundle size);

[0046] Interleave size;

[0047] Precoding granularity;

[0048] Control the total number of CCEs in the resource pool;

[0049] Controls the number of resource blocks in a resource set;

[0050] Controls the number of symbols in the resource set.

[0051] The channel monitoring method of an embodiment of the present application monitors PDCCH in at least two physical downlink control channel PDCCH monitoring opportunities, and each of the PDCCH monitoring opportunities corresponds to a part of the control channel element CCE of the PDCCH, so that the terminal can realize joint detection of PDCCH based on multiple PDCCH monitoring opportunities, thereby improving the transmission performance of PDCCH.

[0052] Optionally, the index of the resource corresponding to the information carried by the CCE in each PDCCH monitoring opportunity is the same.

[0053] That is, the CCEs are distributed at the same position in each PDCCH monitoring opportunity.

[0054] Optionally, the index of the resource corresponding to the CCE in each PDCCH monitoring opportunity is determined according to the number of the PDCCH monitoring opportunity.

[0055] For example, the offset value of the starting position of the information carried by the CCE transmitted in the j-th PDCCH monitoring opportunity is related to j.

[0056] Further optionally, the number of the PDCCH monitoring opportunity is determined according to at least one of the following:

[0057] chronological order;

[0058] frequency order;

[0059] Serving cell index;

[0060] Control resource set indexing;

[0061] Search space collection index.

[0062] For example, multiple PDCCH monitoring opportunities are numbered in order from early to late in time at different times; or multiple PDCCH monitoring opportunities are in different service cells and are sorted in order from small to large or from large to small according to the service cell index; or multiple different frequencies at the same time are numbered in order from low to high or from high to low according to the frequency; or multiple PDCCH monitoring opportunities are in different CORESETs and are numbered in order from large to small or from small to large according to the CORESET index.

[0063] Optionally, before monitoring the PDCCH in at least two physical downlink control channel (PDCCH) monitoring opportunities, the method further includes:

[0064] The number of the CCEs corresponding to each of the PDCCH monitoring opportunities is determined.

[0065] In the embodiment of the present application, the number of CCEs corresponding to each PCCH monitoring opportunity may be equal or unequal.

[0066] When the number of CCEs corresponding to each of the PDCCH monitoring opportunities is the same, determining the number of CCEs corresponding to each of the PDCCH monitoring opportunities includes:

[0067] The number of the CCEs corresponding to each PDCCH monitoring opportunity is determined according to the aggregation level of the PDCCH and the number of the PDCCH monitoring opportunities.

[0068] For example, the aggregation level of the transmitted PDCCH is L, and monitoring is performed in N PDCCH monitoring opportunities. Then, the number of CCEs corresponding to each PDCCH monitoring opportunity is L / N.

[0069] When the number of CCEs corresponding to each PDCCH monitoring opportunity is different, the number of CCEs corresponding to each PDCCH monitoring opportunity includes:

[0070] The number of CCEs corresponding to each PDCCH monitoring opportunity is determined according to an instruction set by the network or according to a preset number of CCEs. That is, the number of CCEs corresponding to each PDCCH monitoring opportunity is preset or indicated by a network device.

[0071] In one embodiment of the present application, assuming that the aggregation level of a PDCCH is L, that is, L CCEs are required for PDCCH transmission, the network device can configure these L CCEs to be distributed in multiple PDCCH MOs (that is, L CCEs are transmitted in multiple PDCCH MOs). For example, L CCEs are distributed in 2 PDCCH MOs, and L / 2 CCEs are transmitted in each PDCCH MO. The above-mentioned multiple PDCCH MOs can be indicated by the network, and the multiple MOs can belong to the same CORESET or different CORESETs, and belong to the same or different search space sets. The UE monitors the PDCCH in the multiple PDCCH MOs indicated by the network.

[0072] Multiple CCE parts of the PDCCH are transmitted in different PDCCH MOs, and the index of the resource corresponding to the CCE in each PDCCH MO is the same, or the starting position of the corresponding CCE in each PDCCH MO has a certain mapping position relationship with the PDCCH MO. A certain mapping position relationship is that the CCE number is related to the PDCCH MO number. For example,

[0073]

[0074] Among them, for any common search space (CSS), For a UE specific search space (UE Specific Search Space, USS), Y p,-1 =n RNTI ≠0, pmod3=0, A p =39827; when pmod3=1, A p =39829; when pmod3=2, A p =39839; D = 65537; i = 0,…, L-1, where L represents the aggregation level;

[0075] N CCE,p is the number of CCEs, which are numbered from 0 to N in CORESET p (CORESET numbered p). CCE,p -1 order numbering; n RNTI C-RNTI is the cell radio network temporary identifier;

[0076] If the higher layer signaling configures a carrier indicator field for the serving cell monitored by PDCCH, n CI is the value of the carrier indicator field, otherwise, for any CSS, n CI =0;

[0077] in, The UE is configured in the corresponding CI The number of PDCCH candidates with aggregation level L monitored in the SS set s of the serving cell;

[0078] For any CSS, For a USS, is the n of all configurations CI The corresponding value The maximum value in .

[0079] f(mo_idx)=mo_idx*N, where N is a positive integer and mo_idx represents the index of the monitoring opportunity MO.

[0080] By using the above formula, the UE can determine the resources of some CCE transmissions of the PDCCH in different monitoring opportunities, and then perform joint PDCCH detection on the CCEs in different monitoring opportunities, thus avoiding the need for the UE to conduct multiple attempts of combining two different PDCCH monitoring opportunities for joint detection.

[0081] Optionally, the transmission configuration indication TCI states corresponding to different PDCCH monitoring opportunities are the same or different.

[0082] The TCI states corresponding to the at least two PDCCH monitoring opportunities are one or more TCI states configured by the network device;

[0083] Alternatively, the TCI states corresponding to the at least two PDCCH monitoring opportunities are one or more TCI states activated by a media access layer control unit MAC-CE.

[0084] In an embodiment of the present application, for PDCCH monitoring of multiple PDCCH MOs, the UE can use different TCI states to monitor in different PDCCH MOs. If multiple PDCCH MOs belong to the same CORESET, the network can use RRC signaling or MAC-CE to indicate multiple TCI states. The UE uses the corresponding TCI state to monitor the PDCCH in a cyclic order on multiple PDCCH MOs based on the order of the PDCCH MOs and the number of the TCI state.

[0085] For example, the network is configured to perform PDCCH monitoring on two PDCCH MOs, each PDCCH MO transmits L / 2 CCEs of a PDCCH with aggregation level L, and the network indicates two TCI states through RRC or MAC-CE, indexed as n1 and n2, then the UE uses TCI states n1 and n2 for monitoring on the two PDCCH MOs respectively.

[0086] Alternatively, the network is configured to perform PDCCH monitoring on 4 PDCCH MOs, each PDCCH MO transmits L / 4 CCEs of PDCCH with aggregation level L, and the network indicates 2 TCI states through RRC or MAC-CE, indexed as n1 and n2, then the UE uses TCI states n1, n2, n1, and n2 for monitoring on the 4 PDCCH MOs respectively.

[0087] Optionally, monitoring a physical downlink control channel (PDCCH) in at least two PDCCH monitoring opportunities includes:

[0088] When the blind detection capability corresponding to the PDCCH monitoring within the preset time period configured by the network device is greater than the PDCCH blind detection capability of the terminal on the current serving cell, preferentially monitoring the first PDCCH or preferentially monitoring the second PDCCH in each of the PDCCH monitoring opportunities;

[0089] Among them, the blind detection capability includes the number of blind detections within a preset time period and the number of non-overlapping CCEs within the preset time period, the first PDCCH is a PDCCH configured with N monitoring resources for joint detection, the second PDCCH is a PDCCH other than the first PDCCH, and N is a positive integer greater than 1.

[0090] The priority of the first PDCCH is determined according to N. For example, the larger N is, the higher the priority is, or the smaller N is, the higher the priority is. That is, when there are multiple first PDCCHs, the detection priority of the multiple first PDCCHs is determined according to the size of N.

[0091] In a specific embodiment of the present application, the UE's PDCCH blind detection capability on each serving cell includes the maximum number of blind detections and the maximum number of non-overlapping CCEs. However, the network may actually configure PDCCH detection within a time period (one or more slots or symbols) such that the number of blind detections or the number of non-overlapping CCEs exceeds the UE's blind detection capability. In this case, the UE needs to abandon PDCCH monitoring in SS sets with higher USS index values.

[0092] When PDCCH detection is performed in multiple PDCCH MOs and each PDCCH MO transmits only part of the CCEs of the PDCCH, the above-mentioned rule for giving up monitoring of the PDCCH can be further optimized.

[0093] For example, within each PDCCH MO, the UE prioritizes detection of PDCCHs configured with N > 1 PDCCH MO joint detection. This ensures UE PDCCH detection performance. A larger value for N indicates a higher priority, while a smaller value indicates a lower priority. This solution is generally more applicable when some CCEs of the PDCCH transmitted within each PDCCH MO cannot be correctly decoded.

[0094] Alternatively, the UE may prioritize detecting PDCCHs other than the PDCCH configured for joint detection of N PDCCH MOs. For example, when the PDCCH MO is an MO other than the first PDCCH MO among the N PDCCH MOs, the priority of monitoring the partially transmitted PDCCH may be lowered. That is, the priority of the PDCCH that has been partially detected by the CCE is lowered. This solution requires that the PDCCH of the partial CCE transmitted by the first PDCCH MO is a PDCCH that can be correctly decoded. If it is necessary to monitor multiple PDCCHs with different N values ​​in the same PDCCH MO, the smaller the N value, the higher the priority.

[0095] The higher the priority, the higher the priority is, indicating that the PDCCH to be detected is given priority or the PDCCH not to be given priority in the process of determining whether to detect / abandon the PDCCH in the corresponding search space set.

[0096] Optionally, the channel monitoring method of the embodiment of the present application further includes:

[0097] Determining a terminal behavior indicated by the PDCCH according to a time unit in which a last PDCCH monitoring opportunity of the at least two PDCCH monitoring opportunities is located;

[0098] The terminal behavior includes at least one of the following:

[0099] According to the time domain resource allocation TDRA indicated by PDCCH, the time resources for physical uplink shared channel PUSCH transmission or PDSCH reception are determined;

[0100] Determine the time resource for transmitting the physical uplink control channel (PUCCH) for hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback according to the PDCCH indication;

[0101] Bandwidth part BWP switching time;

[0102] BWP switching delay;

[0103] Start or restart the discontinuous reception inactivity timer;

[0104] The minimum K0 effective time, K0 is the time slot offset between the PDCCH that transmits PDSCH scheduling information and the scheduled PDSCH;

[0105] The minimum K2 effective time, K2 is the time slot offset between the PDCCH that transmits PUSCH scheduling information and the scheduled PUSCH;

[0106] The effective time of the search space set switch;

[0107] Indicates the time slot resource where the channel state information reference signal CSI-RS for aperiodic channel state information CSI reporting is located.

[0108] In an embodiment of the present application, when the network is configured to transmit PDCCH on multiple MOs, where each MO only transmits part of the CCE of the PDCCH, the UE behavior indicated by the PDCCH is determined based on the last MO among the multiple MOs as the reference time.

[0109] If PDCCH is used to schedule PDSCH reception or PUSCH transmission, the corresponding reception or transmission time uses the time resource of the last PDCCH MO as the reference time, and the reception or transmission symbols of PDSCH or PUSCH are determined according to the scheduling information indicated by PDCCH.

[0110] Similarly, if PDCCH triggers aperiodic CSI reporting, the corresponding CSI-RS resource is determined according to the last PDCCH MO among multiple PDCCH MOs, usually in the time slot where the last PDCCH MO is located, or in a time slot determined by the time offset configured by the network.

[0111] For some non-scheduled PDCCHs, for example, PDCCHs indicating the release of semi-statically scheduled PDSCHs, the UE determines the PUCCH resources for HARQ-ACK feedback based on the end symbol of the PDCCH and the indication of the HARQ-ACK time resources in the PDCCH. When the network is configured to transmit PDCCHs in multiple PDCCH MOs and some CCEs monitor PDCCHs in each PDCCH MO, the UE determines the time resources for HARQ-ACK feedback based on the last PDCCH MO.

[0112] If the PDCCH contains a bandwidth part indicator field and indicates a BWP different from the currently active BWP, the UE switches to the new BWP. If the network configures the UE to monitor PDCCHs on multiple PDCCH MOs, each of which monitors a portion of the CCEs of the PDCCH, the UE switches to the reference BWP in the subframe or timeslot of the reference PDCCH MO after detecting any of the N PDCCH MOs. This means starting or restarting the BWP Inactivity Timer from the subframe or timeslot where the reference PDCCH MO is located.

[0113] The time point when the UE starts to perform BWP switching, or the time point when the bwpInactivityTimer is started or restarted, the reference PDCCH MO of the above PDCCH MO can be used as the reference time point, which can be the following information of the reference PDCCH MO:

[0114] Start symbol, end, next symbol after end;

[0115] The time slot, subframe, or the next time slot or next subframe.

[0116] The reference PDCCH MO may be:

[0117] The last MO among N PDCCH MOs;

[0118] The last valid MO among N PDCCH MOs;

[0119] After the above reference time point T1, the UE completes the BWP switching. The length of T1 depends on the UE capability.

[0120] Similarly, for PDCCH indicating the following functions:

[0121] Start or restart the discontinuous reception inactivity timer (drx InactivityTimer), with the effective time being T2;

[0122] Minimum K0, k2 takes effect at T3;

[0123] The effective time of the search space set switch is T4;

[0124] If the PDCCH is monitored in multiple PDCCH MOs, and each PDCCH MO only monitors part of the CCEs of the PDCCH, then the reference time of the above-mentioned validity time is the last MO among the multiple PDCCH MOs.

[0125] The channel monitoring method of the embodiment of the present application can improve the reliability of PDCCH transmission and the flexibility of network resource allocation by supporting monitoring of PDCCH in multiple monitoring opportunities, each monitoring opportunity corresponding to a partial CCE of a PDCCH.

[0126] like Figure 5 As shown, the embodiment of the present application also provides a channel transmission method, which is applied to a network side device, including:

[0127] Step 301: Configure at least two PDCCH monitoring opportunities;

[0128] Each of the PDCCH monitoring opportunities corresponds to a portion of the control channel elements CCE of the PDCCH.

In the embodiment of the present application, the channel monitoring device provided in the embodiment of the present application is described by taking the channel monitoring method executed by the channel monitoring device as an example.

[0145] A monitoring module 401 is configured to monitor a physical downlink control channel (PDCCH) in at least two PDCCH monitoring opportunities.
