In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application. The embodiments of this application include at least part of the following contents.

Considering that the beam of the Physical Downlink Shared Channel (PDSCH) in Release 16 (Release 16, Rel-16) is dynamically indicated through the downlink control information (Downlink Control Information, DCI), but in In the actual system, the receiving beam of PDSCH does not need to change frequently, so the concept of Unified TCI (Unified TCI) was introduced in Release 17, Rel-17. Unified TCI is used to provide UE-specific PDSCH and All or part of CORESET provides a common quasi-co-located (QCL) information. Unified TCI reuses the indication of the TCI domain in downlink DCI 1_1 or downlink DCI 1_2 in Release 15 (Release 15, Rel-15) or Release 16 (Release 16, Rel-16).

In order to support Unified TCI, three types of CORESET are also introduced, namely CORESET A, CORESET B and CORESET C. The search space associated with CORESET A is used to send UE-specific PDCCH, and the search space associated with CORESETB is only used for sending UE-specific PDCCH. For non-UE-dedicated physical downlink control channel (Physical Downlink Control Channel, PDCCH) reception (such as common search space (Common Search Space, CSS) other than Type 3 (Type3)), CORESET C exists in the search space associated with There are PDCCHs dedicated to UEs and PDCCHs used for public use. For CORESET B and CORESET C, Radio Resource Control (RRC) can configure whether CORESET B and CORESET C should follow the beam indication method of version 17 (Release 17, Rel-17), that is, Unified TCI. When the RRC configuration for such a CORESET does not follow the Rel-17 beam indication method, and there is a TCI domain in the PDCCH associated with the CORESET, the TCI domain is parsed according to the Rel-15/Rel-16 method to obtain the scheduled PDSCH. QCL assumptions.

PDCCH repetition was introduced in Rel-17 to improve the reliability of PDCCH transmission. The specific solution is to carry out two repeated transmissions through the candidate PDCCHs in two associated search spaces, where the two search spaces are respectively The associated CORESET may have different TCI states, that is, the repeatedly transmitted PDCCH is transmitted through two transmission and reception points (Transmission Reception Point, TRP) with different TCI states.

For different reference signal types, there are the following situations for obtaining the QCL reference (i.e., Rel-15/Rel-16 beam indication scheme):

1) Configuration through Radio Resource Control (RRC), such as periodic channel state information reference signal (Channel State Information Reference Signal, CSI-RS)/tracking reference signal (Tracking reference signal, TRS);

2) Activated by the Media Access Control Layer Control Element (MAC CE) through RRC configuration, such as periodic CSI-RS/TRS indicating activation and deactivation through MAC CE, or demodulation of PDCCH Reference signal (Demodulation Reference Signal, DMRS);

3) Through RRC configuration, activated by MAC CE, and using DCI for indication, such as aperiodic channel state information reference signal (Channel State Information Reference Signal, CSI-RS)/tracking reference signal (Tracking reference signal, TRS), or PDCCH DMRS.

For the DCI-based indication method, obtaining QCL information requires three steps: RRC configuration, MAC CE activation and DCI indication. Taking the DMRS pilot of PDSCH as an example, the above process is as follows:

1) The RRC process configures M TCI states (TCI states), and the value of M depends on the UE capabilities;

2) Select up to 8 TCI states (corresponding to the 3-bit TCI information field in DCI) through MAC CE. If M is less than or equal to 8, the TCI state directly corresponds to the TCI in DCI.

For DCI 1_1 (DCI 1_2), if the high-level parameters indicate that TCI is configured, it means that the DCI contains TCI indication information. If the time from receiving the DCI to the corresponding PDSCH transmission interval is greater than or equal to one time period parameter indication, the QCL reference is obtained based on the TCI in the DCI. On the contrary, the CORESET with the lowest latest identification (Identity, ID) is used as the default QCL reference.

For DCI 1_0 or the higher layer parameter indicates that TCI is not configured, if the time interval from receiving the DCI to the corresponding PDSCH transmission is greater than or equal to one time period parameter indication, the relevant information is obtained according to the QCL status of the PDCCH that schedules the PDSCH. Otherwise, with The CORESET with the lowest ID number in the most recent scheduling slot containing CORESET maintains QCL.

In order to facilitate a better understanding of the embodiments of the present application, the problems solved by the present application will be described.

The NR system can perform PDCCH repetition transmission based on Unified TCI. Specifically, CORESET can be grouped, and each group is configured with a different Unified TCI. The search space used for PDCCH repetition is associated with CORESET groups configured with different Unified TCI. Since each PDCCH in the PDCCH repetition carries the same content, whether the TCI information field indicated in the PDCCH repetition updates the TCI state of one CORESET group or updates the TCI state of both CORESET groups is a problem that needs to be solved.

Based on the above problems, this application proposes a PDCCH repetition transmission based on Unified TCI. By clarifying the CORESET role of the TCI information domain in the PDCCH, the QCL assumption of the CORESET is correctly set to ensure that the subsequent channels scheduled based on the CORESET are correct. take over.

The technical solutions of the present application are described in detail below through specific examples.

S210, the network device sends at least one PDCCH, wherein there is at least one CORESET associated search space in the CORESET used to send the at least one PDCCH for repeated transmission of the PDCCH, and there is at least one CORESET in the CORESET used to send the at least one PDCCH. Configured with unified TCI;

S220, the terminal equipment receives the at least one PDCCH;

S230: The terminal equipment determines, based on the received PDCCH, the CORESET to which the TCI status indicated in the at least one PDCCH is applied or the CORESET group to which the applied CORESET belongs;

S240: The terminal equipment determines, based on the TCI status indicated in the at least one PDCCH, the CORESET to which the TCI status indicated in the at least one PDCCH acts or the channel corresponding to the CORESET group to which the applied CORESET belongs.

In the embodiment of the present application, there is at least one CORESET associated search space in the CORESET used to send at least one PDCCH for repeated transmission of PDCCH, and at least one CORESET in the CORESET used to send at least one PDCCH is configured with a unified TCI, Therefore, the terminal equipment can determine the CORESET to which the TCI status indicated in at least one PDCCH acts or the CORESET group to which the acted CORESET belongs based on the received PDCCH, and the terminal equipment determines at least one PDCCH based on the TCI status indicated in the at least one PDCCH. The channel corresponding to the CORESET to which the TCI status indicated in is applied or the CORESET group to which the applied CORESET belongs. That is to say, in the embodiment of this application, when supporting PDCCH repetition transmission based on Unified TCI, the QCL assumption of CORESET can be correctly set by clarifying the CORESET that the TCI status indicated in the PDCCH acts on, to ensure that subsequent scheduling based on the PDCCH Correct reception of the channel.

That is, in the embodiment of the present application, the at least one PDCCH is used by the terminal equipment to determine the CORESET that the TCI status indicated in the at least one PDCCH acts on or the CORESET group to which the acted CORESET belongs, and the CORESET indicated in the at least one PDCCH. The TCI state is used by the terminal equipment to determine the CORESET to which the TCI state indicated in the at least one PDCCH is applied or the channel corresponding to the CORESET group to which the applied CORESET belongs.

In some embodiments, the channel corresponding to the CORESET acted upon by the TCI status indicated in the at least one PDCCH or the CORESET group to which the acted CORESET belongs may include at least one of the following:

PDCCH, PDSCH, Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), a channel used to transmit sounding reference signals (Sounding Reference Signal, SRS), used to transmit non- Periodic CSI-RS channel.

In some embodiments, the network device can configure multiple CORESETs, and configure a common TCI status pool for multiple CORESETs through high-level signaling (such as RRC), or configure a common TCI status pool for multiple CORESETs through high-level signaling (such as RRC). Each CORESET is configured with an independent TCI status pool. Among the multiple CORESETs, at least one CORESET is configured with a unified TCI. There may also be one or more CORESETs configured with a dynamic (Dyanmic) TCI among the multiple CORESETs. (That is, non-Unified TCI). Further, the TCI states associated with the multiple CORESETs are different.

In some embodiments, the network device can configure multiple CORESET groups, and configure a common TCI status pool for multiple CORESET groups through high-level signaling (such as RRC), or configure multiple CORESET groups through high-level signaling (such as RRC). Each CORESET group in the CORESET groups is configured with an independent TCI status pool. Among the multiple CORESET groups, at least one CORESET group is configured with a unified TCI. There can also be one or more CORESETs in the multiple CORESET groups. The group is configured with dynamic (Dyanmic) TCI (that is, non-Unified TCI). Further, the TCI states associated with the multiple CORESET groups are different.

For example, the network device is configured with 5 CORESETs. If it is divided into two groups, group A has 2 (or x) CORESETs, and group B has 3 (or 1 or x) CORESETs. At this time, the CORESETs of group A may be They all apply the same TCI status, that is, this TCI status is applied to this CORESET group.

In some embodiments, the network device can be configured with multiple search spaces, wherein each search space is associated with a CORESET, and at least two search spaces have an associated relationship (for example, there is a QCL between at least two search spaces). ), the search spaces with associated relationships can be used for repeated PDCCH transmissions, and the multiple search spaces also have search spaces for single transmission of PDCCH.

In some embodiments, the search space with associated relationships can be used for PDCCH repetition (repetition) based on multiple transmission points (Multiple transmission points, MTRP).

For example, the network device configures multiple search spaces for the terminal device, two of which have an associated relationship, and the two search spaces are used for MTRP-based PDCCH repetition. The CORESETs corresponding to these two search spaces belong to different CORESET groups, and the network equipment is configured with Unified TCI for these two CORESET groups. Optionally, the network device configures a TCI status pool for each CORESET (or the CORESET group to which the CORESET belongs) through high-level signaling (such as RRC signaling).

For another specific example, the network device configures multiple search spaces for the terminal device, two of which have an associated relationship, and these two search spaces are used for MTRP-based PDCCH repetition. The network device has configured Unified TCI for the CORESET associated with one of the search spaces (or the CORESET group it belongs to); the network device has not configured the corresponding (follow) unified TCI for the CORESET (or CORESET group it belongs to) associated with another search space, and the network device has not configured the corresponding (follow) unified TCI for the CORESET associated with another search space (or the CORESET group it belongs to). That is, when the CORESET associated with the search space performs PDCCH transmission, the DCI in the PDCCH dynamically indicates the TCI status. The network device configures the TCI state pool used by Unified TCI through high-level signaling. If the number of TCI states in the TCI state pool exceeds a certain threshold, the network device activates the threshold number of TCI states through another higher-layer signaling (MAC-CE signaling). The network device also configures another TCI state pool used by CORESET associated with the search space through high-level signaling. The two state pools can be the same state pool or different state pools. If the TCI in the TCI state pool When the number of states exceeds a certain threshold, the network device activates the threshold number of TCI states for two CORESETs (or the CORESET group they belong to) through another (or two) high-level signaling (MAC-CE signaling). Each The TCI status activated by each CORESET (the CORESET group it belongs to) can be different.

In some embodiments, in the above S240, it is assumed that the at least one PDCCH includes PDCCH 0, and the TCI state indicated in PDCCH 0 is TCI state 0, and TCI state 0 acts on CORESET 0 or the CORESET group to which CORESET 0 belongs. In the case where the corresponding TCI state before CORESET 0 or the CORESET group to which CORESET 0 belongs is different from TCI state 0, the terminal device determines that TCI state 0 acts on the channel corresponding to CORESET 0 or the CORESET group to which CORESET 0 belongs after the first duration ( That is, the channel sent or received through CORESET 0 or the CORESET group to which CORESET 0 belongs after the first duration, that is, TCI state 0 takes effect after the first duration). When CORESET 0 or the previous corresponding TCI state of the CORESET group to which CORESET 0 belongs is the same as TCI state 0, the terminal device determines that TCI state 0 acts on TCI state 0 acts on the current and subsequent CORESET 0 or CORESET group to which CORESET 0 belongs. the corresponding channel.
