Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims priority from Chinese Patent Application No. 201811303170.1, filed in China on November 2, 2018, the entire contents of which are incorporated herein by reference. The present application relates to the field of communications technology, and more particularly, to wireless communication methods and apparatus. [Background technology]

[0002] In a mobile communication system, in response to a beam instruction of a Physical Downlink Control Channel (PDCCH), a network device configures K Transmission Configuration Indication (TCI) states for each Control Resource Set (CORESET) by Radio Resource Control (RRC) signaling. If K>1, one TCI state is indicated by a Media Access Control Control Element (MAC CE). If K=1, no extra MAC CE command is required. When a terminal device monitors a CORESET, the terminal device uses the same Quasi-colocation (QCL) information, i.e., the same TCI state, for all search spaces within the CORESET. Based on this TCI state, the terminal device can know the receiving beam of the PDCCH.

[0003] In response to a beam command for a Physical Downlink Shared Channel (PDSCH), a network device configures M TCI states by RRC signaling, and further activates 2N TCI states by using a MAC CE command.Then, the network device notifies the TCI state by an N-bit field of Downlink Control Information (DCI), and the terminal device can obtain a receiving beam for the PDSCH based on the notified TCI state.

[0004] In response to a beam instruction of a Physical Uplink Control Channel (PUCCH), a network device arranges spatial relation information for each PUCCH resource using RRC signaling. If the spatial relation information arranged for a PUCCH resource includes multiple entries, the network device indicates the spatial relation information of one of the entries using a MAC CE.

[0005] For the beam indication of the Physical Uplink Shared Channel (PUSCH), the network device configures the relevant information of the PUSCH through RRC signaling. When the DCI carried by the PDCCH schedules the PUSCH, each code point of the Sounding Reference Signal Resource Indicator (SRI) field in the DCI indicates one SRI, and the SRI is used to indicate the spatial relation of the PUSCH.

[0006] For the beam instruction of the SRS, if the SRS is a periodic SRS, the network device configures a spatial relation for the SRS resource by RRC signaling. If the SRS is a semi-persistent SRS, the network device activates one of a set of spatial relations configured by RRC signaling via a MAC CE command. If the type of SR is aperiodic SRS, the network device configures a spatial relation for the SRS resource by RRC signaling.

[0007] As can be seen from the above description, beam direction for a current uplink / downlink channel or reference signal is generally configured by RRC signaling to configure candidate QCL information or Spatial Relation information, and then further activated by MAC CE command or indicated by DCI. When reconfiguration of candidate QCL information or Spatial Relation information occurs, it is necessary to configure again using RRC signaling, which results in a relatively large upper layer signaling overhead.

[0028] The following clearly and completely describes the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, and not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without any creative effort are within the scope of protection of the present disclosure.

[0029] The technical proposal of the present disclosure can be used in various communication systems, such as Long Term Evolution (LTE) / Long Term Evolution-advanced (LTE-A) systems, New Radio (NR) systems, etc.

User Equipment may be mobile terminals, such as mobile phones (also referred to as "cellular" phones), and computers having mobile terminals, such as portable, pocket, handheld, computer-embedded, or vehicle-mounted mobile devices, that exchange voice and / or data with the Radio Access Network.

[0031] In some embodiments of the present disclosure, a network device is disposed in a radio access network and is used to provide a wireless communication function to a terminal device, and the network device may be, for example, a base station, and the base station may be an evolved base station in LTE (eNB or e-NodeB, evolutionary Node B) and a 5G base station (gNB).

[0032] The following provides a detailed description of the technical solutions provided by the embodiments of the present disclosure in conjunction with the accompanying drawings.

[0033] It should be noted that in some embodiments of the present disclosure, downlink channels include, but are not limited to, PDCCH and PDSCH. Downlink reference signals include, but are not limited to, Cell-specific Reference Signals (CRS), Demodulation Reference Signals (DMRS), and Channel State Information Reference Signals (CSI-RS). Uplink channels include, but are not limited to, PUCCH and PUSCH. Uplink reference signals include, but are not limited to, SRS.

[0034] Fig. 1 shows a method of wireless communication according to an embodiment of the present application. The method shown in Fig. 1 may be performed by a terminal device or a network device. As shown in Fig. 1, the method includes the following steps:

[0035] S110: When a first target control resource set CORESET is placed in a first cell in a target frequency band, determine first target quasi-colocation QCL information of the first target CORESET placed in the first cell.

[0036] In S110, the symbol of the first target CORESET may be a specific value, for example, the symbol of the first target CORESET is 0, that is, the first target CORESET is CORESET #0.

[0037] S120: Determine, based on the first target QCL information, QCL information of a downlink channel or a downlink reference signal on at least one cell and spatial relationship information of an uplink channel or an uplink reference signal on the at least one cell.

[0038] The at least one cell in S120 may include the first cell or may not include the first cell. The at least one cell may be located in the same frequency band or may not be located in the same frequency band. For example, some of the at least one cell are located in one frequency band, and another part of the cells are located in another frequency band.

[0039] The first target QCL information in S120 may be determined by the terminal device from among the first QCL information set to which the first target QCL information belongs, based on an instruction from the MAC CE. The first QCL information set is configured by the network device via RRC signaling. For example, the network device carries and configures the information of the first QCL information set using the higher layer parameter pdsch-Config in the RRC signaling.

[0040] Taking the first target CORESET as an example, the network equipment configures related information of CORESET #0 for the first cell, and the related information includes a QCL information set configured for CORESET #0 (it may be understood that the network equipment configures a QCL pool or a TCI state pool for CORESET #0). If there are multiple QCL information in the candidate QCL information set, the network equipment activates (or is called indication) one of the QCL information for CORESET #0 by the MAC CE, and the activated (or indicated) QCL information is the first target QCL information. If the QCL information set needs to be rearranged, the network equipment may perform the rearrangement by RRC signaling and reactivate (or indicate) the QCL information of CORESET #0 using the MAC CE.

[0041] Specifically, in some embodiments, in S120, determining QCL information of downlink channels or downlink reference signals on at least one cell includes determining QCL information of downlink channels or downlink reference signals on some or all of the bandwidth portions BWP on each cell of the at least one cell, and determining spatial relationship information of uplink channels or uplink reference signals on at least one cell includes determining spatial relationship information of uplink channels or uplink reference signals on some or all of the BWP on each cell of the at least one cell.

[0042] The following describes the technical solution of the present disclosure in conjunction with specific examples.

[0043] Example A The at least one cell includes a first cell, and in S120, determining QCL information of a downlink channel or a downlink reference signal on the at least one cell based on the first target QCL information includes determining that the QCL information of the downlink channel or the downlink reference signal on the first cell is the first target QCL information. For example, the QCL information of CORESET #0 on the first cell is the QCL information of a PDCCH on the first cell.

[0044] Alternatively, the at least one cell includes a first cell, and in S120, determining QCL information of a downlink channel or a downlink reference signal on at least one cell based on the first target QCL information includes determining that a QCL information set of a downlink channel or a downlink reference signal on the first cell is a first QCL information set to which the first target QCL information belongs, and determining QCL information of the downlink channel or the downlink reference signal on the first cell from the QCL information set of the downlink channel or the downlink reference signal on the first cell. Here, determining QCL information of the downlink channel or the downlink reference signal on the first cell from the QCL information set of the downlink channel or the downlink reference signal of the first cell may be performed based on an instruction of a MAC CE.

[0045] Further, or in a case where the at least one cell includes a first cell, multiple CORESETs are arranged on the first cell, and the multiple CORESETs include a first target CORESET, in S120, determining QCL information of a downlink channel or a downlink reference signal on at least one cell based on the first target QCL information includes determining, based on an instruction from a MAC CE, QCL information of a CORESET other than the first target CORESET among the multiple CORESETs from the first QCL information set to which the first target QCL information belongs.

[0046] For example, for a CORESET whose number is not 0 and is placed on a first cell, the network device activates (or indicates) one of the QCL information sets of CORESET #0 via the MAC CE, and sets it as the QCL information of this CORESET, i.e., the QCL information of this CORESET uplink / downlink channel or downlink reference signal.

[0047] Example b The at least one cell includes a first cell and a second cell, and the first target CORESET is not configured in the second cell. Accordingly, in S120, determining QCL information of a downlink channel or a downlink reference signal on the at least one cell based on the first target QCL information includes determining QCL information of a downlink channel or a downlink reference signal on the second cell based on the first target QCL information.

[0048] Specifically, determining the QCL information of the downlink channel or the downlink reference signal on the second cell based on the first target QCL information includes determining that the QCL information of the downlink channel or the downlink reference signal on the second cell is the first target QCL information. Or, it may be understood that the first target QCL information of the first target CORESET arranged on the first cell is the QCL information of the downlink channel or the downlink reference signal on the second cell.

[0049] Or, determining QCL information of a downlink channel or a downlink reference signal on the second cell based on the first target QCL information includes determining QCL information of a downlink channel or a downlink reference signal on the second cell based on a first QCL information set to which the first target QCL information belongs.

[0050] For example, it is determined that the QCL information set of the downlink channel or the downlink reference signal on the second cell is the first QCL information set to which the first target QCL information belongs, and the QCL information of the downlink channel or the downlink reference signal on the second cell is determined from the QCL information set of the downlink channel or the downlink reference signal on the second cell. Here, the QCL information of the downlink channel or the downlink reference signal on the second cell may be determined from the first QCL information set based on a rule set in advance. Or, for the terminal device, the QCL information of the downlink channel or the downlink reference signal on the second cell may be determined from the first QCL information set based on an instruction from the network device.

[0051] Optionally, in example b, the cell index of the first cell satisfies a first preset rule, for example, the first cell is a cell having a smallest cell index among the cells in which the first target CORESET is located in the frequency band.

[0052] Optionally, in example b, the second cell is located within the target frequency band, ie the first cell and the second cell are located within the same frequency band.

[0053] Example c The first target CORESET is not deployed in any cell in a frequency band in which each cell of the at least one cell is located. As shown in Figure 2, the method shown in Figure 1 further includes the following steps.

[0054] S130: A second QCL information set to be placed on a third cell is determined.

[0055] The network equipment may configure a second set of QCL information for the third cell via RRC signaling.

[0056] It should be noted that the third cell may be a cell within the frequency band in which a cell of the at least one cell is located, or the frequency band in which the third cell is located may be different from the frequency band in which any one of the at least one cell is located.

[0057] Here, the third cell may be a cell whose cell index satisfies a certain rule within the frequency band in which the third cell is located, for example, the third cell may be a cell having the smallest cell index within the frequency band in which the third cell is located.

[0058] For example, at least one cell is located in a target frequency band, and a third cell is located in a target frequency band. That is, when a first target CORESET is not configured in all cells in a frequency band, the QCL information of the downlink channel or the downlink reference signal on a cell in the frequency band can be determined based on the QCL information set configured on a cell in the frequency band.

[0059] S140: Determine QCL information of a downlink channel or a downlink reference signal on the at least one cell based on a second set of QCL information.

[0060] For example, determining QCL information of a downlink channel or a downlink reference signal on at least one cell based on the second QCL information set includes determining second target QCL information of a second target CORESET to be located in a third cell from the second QCL information set, and determining that the QCL information of the downlink channel or the downlink reference signal on the at least one cell is the second target QCL information. The network device may activate (or indicate) one QCL information from the second QCL information set as the second target QCL information for the second target CORESET using the MAC CE.

[0061] Alternatively, determining QCL information of a downlink channel or a downlink reference signal on at least one cell based on the second QCL information set includes determining that the QCL information set of a downlink channel or a downlink reference signal on at least one cell is a second QCL information set, and determining the QCL information of the downlink channel or the downlink reference signal on the at least one cell from the QCL information set of the downlink channel or the downlink reference signal on the at least one cell.

[0062] In example c, the cell index of the third cell satisfies the second preset rule, and / or the number of the second target CORESET satisfies the third preset rule, and / or the number of the Bandwidth Part (BWP) in which the second target CORESET is located satisfies the fourth preset rule.

[0063] For example, the third cell is a cell having a specific Cell Index (e.g., the smallest Cell Index) in the frequency band. The second target CORESET may be a CORESET with a specific number, for example, the CORESET with the smallest number. The BWP in which the second target CORESET is located may be a BWP with a specific number, for example, the BWP with the smallest number in the third cell. The "number" here may be expressed as an "indicator or index."

[0064] For example, when the first target CORESET is CORESET#0, if CORESET#0 is not configured in any cell in a frequency band, the network equipment may configure QCL information for a specific CORESET on a specific cell in this frequency band, and all CORESETs on all cells in this frequency band will use this QCL information.

[0065] example d The at least one cell includes a first cell, and in S120, determining spatial relationship information of uplink channels or uplink reference signals on the at least one cell based on the first target QCL information includes determining a reference signal RS set corresponding to a first transmission configuration indication TCI state for indicating the first target QCL information, and determining spatial relationship information of uplink channels or uplink reference signals on the first cell based on a source RS in the RS set.

[0066] For example, the source RS (or referred to as Reference RS) in the RS set corresponding to the TCI state indicating the first target QCL information of CORESET#0 is set as the source RS in the spatial relation information of the PUCCH. If the terminal device determines a receiving beam for receiving CORESET#0 based on the TCI state indicating the first target QCL information of CORESET#0, it transmits the PUCCH using a transmitting beam (other spatial parameters of the beam are the same except for the opposite direction) in the direction of this receiving beam.

[0067] example e The at least one cell includes a first cell, and in S120, determining spatial relationship information of uplink channels or uplink reference signals on the at least one cell based on the first target QCL information includes determining spatial relationship information of uplink channels or uplink reference signals on the first cell based on a first QCL information set to which the first target QCL information belongs.

[0068] Optionally, determining spatial relationship information of an uplink channel or uplink reference signal on the first cell based on a first QCL information set to which the first target QCL information belongs includes determining a second TCI state for indicating all QCL information in the first QCL information set, determining candidate spatial relationship information of an uplink channel or uplink reference signal on the first cell based on all source RSs in an RS set corresponding to the second TCI state, and determining spatial relationship information of an uplink channel or uplink reference signal on the first cell from the candidate spatial relationship information.

[0069] For example, all Source RSs in the RS set corresponding to the TCI state indicating the QCL information set of CORESET#0 are set as Source RSs in the candidate Spatial Relation information of PUCCH, and one subset is selected from the Source RSs in the candidate Spatial Relation information of PUCCH to be set as the RS in the Spatial Relation information of PUCCH. Alternatively, it is described that the candidate Spatial Relation information of PUCCH is determined based on all Source RSs in the RS set corresponding to the TCI state indicating the QCL information set of CORESET#0, and one subset is selected from the candidate Spatial Relation information to be set as the Spatial Relation information of PUCCH.

[0070] Furthermore, determining spatial relationship information of an uplink channel or an uplink reference signal on the first cell from among the candidate spatial relationship information includes determining spatial relationship information of an uplink channel or an uplink reference signal on the first cell from among the candidate spatial relationship information based on an indication of radio resource control (RRC) signaling and / or MAC CE. For example, there are a total of 64 Source RSs in the candidate spatial relation information, and the network device indicates 8 of them as Source RSs in the spatial relation information of the PUCCH using RRC signaling or MAC CE.

[0071] Optionally, the maximum number of spatial relationship information that can be configured on a cell is equal to or greater than the number of QCL information in the first QCL information set, and determining the spatial relationship information of an uplink channel or uplink reference signal on the first cell based on the first QCL information set to which the first target QCL information belongs includes: determining a second TCI state for indicating all QCL information in the first QCL information set; determining candidate spatial relationship information of an uplink channel or uplink reference signal on the first cell based on all source RSs in the RS set corresponding to the second TCI state; and determining the spatial relationship information of an uplink channel or uplink reference signal on the first cell from the candidate spatial relationship information.

[0072] For example, if the maximum number of pieces of PUCCH Spatial Relation information that can be arranged by a network device is equal to or greater than the number of QCL information pieces in the QCL information set of CORESET#0, the QCL information in the QCL information set of CORESET#0 can be directly used as the PUCCH Spatial Relation information.

[0073] Optionally, determining spatial relationship information of uplink channels or uplink reference signals on the first cell based on the first QCL information set to which the first target QCL information belongs includes determining a preset number of QCL information from the first QCL information set, and determining spatial relationships of uplink channels or uplink reference signals on the first cell based on a source RS in an RS set corresponding to a third TCI state for indicating the preset number of QCL information. Here, determining the preset number of QCL information from the first QCL information set may be based on a protocol agreement. For the terminal device, determining the preset number of QCL information from the first QCL information set may further be based on an instruction from a network device.

[0074] For example, a certain number of QCL information pieces (e.g., eight QCL information pieces having the smallest entry in the TCI state when arranging the QCL information pieces) are selected from the QCL information set of CORESET#0, and the spatial relation information of the PUCCH is determined by setting the Source RS in the RS set corresponding to the TCI state indicating this certain number of QCL information pieces as the Source RS of the spatial relation information of the PUCCH.

[0075] example f The at least one cell includes a first cell and a fourth cell, and a first target CORESET is not configured in the fourth cell. In S120, determining spatial relationship information of uplink channels or uplink reference signals on the at least one cell based on the first target QCL information includes determining spatial relationship information of uplink channels or uplink reference signals on the fourth cell based on the first target QCL information.

[0076] That is, based on the first target QCL information of the first target CORESET arranged in the first cell, channel Or, spatial relationship information of the uplink reference signal may be determined.

[0077] Optionally, determining spatial relationship information of an uplink channel or uplink reference signal on the fourth cell based on the first target QCL information includes determining a first TCI state for indicating the first target QCL information, and determining spatial relationship information of an uplink channel or uplink reference signal on the fourth cell based on a source RS in the RS set corresponding to the first TCI state.

[0078] For example, the Source RS in the RS set corresponding to the TCI state indicating the first target QCL information of CORESET#0 arranged on the first cell is set as the Source RS in the Spatial Relation information of the PUCCH of the fourth cell. If the terminal device determines a receiving beam for receiving CORESET#0 based on the TCI state indicating the first target QCL information of CORESET#0, it transmits the PUCCH using a transmitting beam (other spatial parameters of the beam are the same except for the opposite direction) in the direction of this receiving beam on the fourth cell.

[0079] Optionally, determining spatial relationship information of an uplink channel or an uplink reference signal on the fourth cell based on the first target QCL information includes determining spatial relationship information of an uplink channel or an uplink reference signal on the fourth cell based on a first QCL information set to which the first target QCL information belongs.

[0080] For example, determine a second TCI state for indicating all information in the first QCL information set, and determine candidate spatial relationship information of uplink channels or uplink reference signals in a fourth cell according to all source RSs in an RS set corresponding to the second TCI state. From the candidate spatial relationship information, determine the spatial relationship information of uplink channels or uplink reference signals in the fourth cell.

[0081] Or, a predetermined number of QCL information is determined from the first QCL information set, and spatial relationship information of an uplink channel or an uplink reference signal on the fourth cell is determined based on a source RS in an RS set corresponding to a TCI state indicating the predetermined number of QCL information.

[0082] Optionally, in example f, the fourth cell is located within the target frequency band, ie the first cell and the fourth cell are located within the same frequency band.

[0083] Example G If the first target CORESET is not configured in any cell within the frequency band in which each cell of the at least one cell is located, as shown in FIG. 3, the method shown in FIG. 1 further includes the following steps:

[0084] S150: A third QCL information set to be placed on a fifth cell is determined.

[0085] It should be noted that the fifth cell may be a cell in a frequency band in which a certain cell of the at least one cell is located, or the frequency band in which the fifth cell is located may be different from the frequency band in which any one of the at least one cell is located. Here, the fifth cell may be a cell whose cell index satisfies a certain rule in the frequency band in which the fifth cell is located, for example, the fifth cell may be a cell having a smallest cell index in the frequency band in which the fifth cell is located.

[0086] S160: Determine spatial relationship information of uplink channels or uplink reference signals on at least one cell based on the third QCL information set.

[0087] Optionally, at least one cell is located in a target frequency band, and a fifth cell is located in the target frequency band, that is, when the first target CORESET is not configured in all cells in a frequency band, the spatial relationship information of the uplink channel or uplink reference signal in a cell in the frequency band can be determined according to the QCL information set configured on a cell in the frequency band.

[0088] Optionally, determining spatial relationship information of uplink channels or uplink reference signals on at least one cell based on the third QCL information set includes determining a TCI state for indicating all QCL information in the third QCL information set, determining candidate spatial relationship information of uplink channels or uplink reference signals on at least one cell based on all source RSs in an RS set corresponding to the TCI state for indicating all QCL information in the third QCL information set, and determining spatial relationship information of uplink channels or uplink reference signals on at least one cell from the spatial relationship information.

[0089] Optionally, determining spatial relationship information of uplink channels or uplink reference signals on at least one cell based on the third QCL information set includes determining a predetermined number of QCL information from the third QCL information set, and determining spatial relationship information of uplink channels or uplink reference signals on at least one cell based on a source RS in an RS set corresponding to a TCI state for indicating the predetermined number of QCL information.

[0090] Optionally, determining spatial relationship information of uplink channels or uplink reference signals on at least one cell based on the third QCL information set includes determining third target QCL information of a third target CORESET located in a fifth cell from the third QCL information set, and determining spatial relationship information of uplink channels or uplink reference signals on at least one cell based on the third target QCL information. The network device may activate (or indicate) one QCL information from the third QCL information set as third target QCL information for the third target CORESET using the MAC CE.

[0091] Here, determining spatial relationship information of uplink channels or uplink reference signals on at least one cell based on the third target QCL information may include determining a TCI state for indicating the third target QCL information, and determining spatial relationship information of uplink channels or uplink reference signals on at least one cell based on a source RS in an RS set corresponding to the TCI state for indicating the third QCL information.

[0092] In example g, the cell index of the fifth cell satisfies the fifth preset rule, and / or the number of the third target CORESET satisfies the sixth preset rule, and / or the number of the bandwidth portion BWP in which the third target CORESET is located satisfies the seventh preset rule.

[0093] For example, the fifth cell is a cell having a specific Cell Index (e.g., the smallest Cell Index) in the frequency band. The third target CORESET may be a specific numbered CORESET, for example, the smallest numbered CORESET. The BWP in which the third target CORESET is located may be a specific numbered BWP, for example, the smallest numbered BWP in the fifth cell.

[0094] example h The at least one cell includes a first cell and a sixth cell, and no QCL information set is configured in the sixth cell. The method shown in Fig. 1 further includes: determining that the QCL information set of the sixth cell is a first QCL information set to which the first target QCL information belongs; and determining, according to the QCL information set of the sixth cell, QCL information of the downlink channel or downlink reference signal on the sixth cell and spatial relationship information of the uplink channel or uplink reference signal on the sixth cell.

[0095] It can be understood that in example h, the first QCL information set of the first cell is set as the QCL information set of the sixth cell, and then the QCL information of the downlink channel or the downlink reference signal on the sixth cell is determined based on the QCL information set of the sixth cell, and the QCL information of the downlink channel or the downlink reference signal on the first cell is determined based on the first QCL information set to which the first QCL information of the first target CORESET arranged in the first cell belongs in the above example, are realized in the same way.To avoid duplication, the description is omitted here.

[0096] Similarly, determining the spatial relationship information of the uplink channel or the uplink reference signal on the sixth cell based on the QCL information set of the sixth cell may refer to the implementation method of determining the spatial relationship information of the uplink channel or the uplink reference signal on the first cell based on the first QCL information set to which the first QCL information of the first target CORESET arranged in the first cell belongs in the above example. Description is omitted here.

[0097] The first cell in example h may be the cell having the smallest Cell Index among the cells in which the QCL information set is arranged.

[0098] Optionally, the sixth cell is located within the target frequency band, i.e. the first cell and the sixth cell are located within the same frequency band.

[0099] Example i The at least one cell includes a first cell and a seventh cell, and the seventh cell has no QCL information set configured. The method of FIG. 1 further includes: determining that the QCL information of the downlink channel or the downlink reference signal on the seventh cell is the QCL information of the downlink channel or the downlink reference signal on the first cell, and / or determining spatial relationship information of the uplink channel or the uplink reference signal on the seventh cell based on the QCL information of the downlink channel or the downlink reference channel on the first cell.

[0100] For example, the QCL information of the PDCCH of the first cell is determined as the QCL information of the downlink channel or the downlink reference signal on the seventh cell, or the spatial relationship information of the uplink channel (e.g., PUCCH) or the uplink reference signal (e.g., SRS) on the seventh cell is determined based on the QCL information of the PDCCH of the first cell.

[0101] Optionally, determining the spatial relationship information of the uplink channel or uplink reference signal on the seventh cell based on the QCL information of the downlink channel or downlink reference channel on the first cell includes determining the spatial relationship information of the uplink channel or uplink reference signal on the seventh cell based on a source RS in the RS set corresponding to a TCI state for indicating the QCL information of the downlink channel or downlink reference signal on the first cell.

[0102] Or, determining spatial relationship information of an uplink channel or uplink reference signal on the seventh cell based on QCL information of a downlink channel or downlink reference signal on the first cell includes determining candidate spatial relationship information of an uplink channel or uplink reference signal on the seventh cell based on all source RSs in an RS set corresponding to a TCI state for indicating all QCL information in the QCL information set to which the QCL information of the downlink channel or downlink reference signal on the first cell belongs, and determining the spatial relationship information of the uplink channel or uplink reference signal on the seventh cell from among the candidate spatial relationship information.

[0103] Alternatively, determining spatial relationship information of an uplink channel or uplink reference signal on the seventh cell based on QCL information of a downlink channel or downlink reference signal on the first cell includes selecting a predetermined number of QCL information from a QCL information set to which the QCL information of the downlink channel or downlink reference signal on the first cell belongs, and determining spatial relationship information of the uplink channel or uplink reference signal on the seventh cell based on a source RS in an RS set corresponding to a TCI state for indicating the predetermined number of QCL information.

[0104] Optionally, the seventh cell is located within the target frequency band, i.e. the first cell and the seventh cell are located within the same frequency band.

[0105] example j The at least one cell includes a first cell and an eighth cell, and the eighth cell does not have a QCL information set configured. The method shown in FIG. 1 further includes determining that the spatial relationship information of the uplink channel or uplink signal on the eighth cell is the spatial relationship information of the uplink channel or uplink reference signal on the first cell.

[0106] For example, the spatial relationship information of the PUCCH of the first cell is determined to be the spatial relationship information of the uplink channel or uplink reference signal on the eighth cell.

[0107] Optionally, the first cell in examples i and j may be the cell having the smallest Cell Index among the cells in which the QCL information set is located.

[0108] Optionally, the eighth cell is located within the target frequency band, i.e. the first cell and the eighth cell are located within the same frequency band.

[0109] According to examples b, c, f, g, h, i and j, a terminal device can determine QCL information of downlink channels or downlink reference signals and spatial relationship information of uplink channels or uplink reference signals on other cells based on QCL information (or QCL information set) of a specific CORESET configured on a specific cell, which does not need to be configured by a network device via higher layer signaling, and can reduce higher layer signaling overhead.

[0110] 4 is a method of wireless communication according to an embodiment of the present disclosure. The method shown in FIG. 4 may be performed by a terminal device. As shown in FIG. 4, the method of wireless communication according to an embodiment of the present disclosure includes the following steps:

[0111] S410: Receive a spatial transmission information set including a pseudo-colocation QCL information set and a spatial relationship information set.

[0112] S420: Based on the QCL information set, determine QCL information of a downlink channel or a downlink reference signal on at least one cell, and based on the spatial relationship information set, determine spatial relationship information of an uplink channel or an uplink reference signal on the at least one cell.

[0113] It should be noted that the spatial transmission information set received at S410 includes QCL information and a spatial relationship information set. It can be understood that the network device configures the QCL information set for the downlink on the cell of the terminal device, and configures the spatial relationship information set for the uplink on the cell of the terminal device.

[0114] Optionally, as one example, the QCL information is a shared QCL information set of all cells of the at least one cell, and the spatial relationship information set is a shared spatial relationship information set of all cells of the at least one cell, or the QCL information set is configured by a network equipment for a first target cell in the at least one cell, and the spatial relationship information set is configured by a network equipment for a second target cell in the at least one cell.

[0115] Optionally, the cell index of the first target cell satisfies a first preset rule and / or the cell index of the second target cell satisfies a second preset rule, for example, the first target cell is a cell with a smallest cell index among the at least one cell, and the second target cell is a cell with a largest cell index among the at least one cell.

[0116] In other words, the network equipment may configure the same QCL information set for the cells of the terminal equipment, and the QCL information on each cell may be selected from this QCL information set. Or the network equipment may configure the QCL information set for a specific cell among the cells of the terminal equipment, and the QCL information on each cell may be selected from the QCL information set arranged on the specific cell. Or the network equipment may configure the same spatial relationship information set for the cells of the terminal equipment, and the spatial relationship information on each cell may be selected from the spatial relationship information set. Or the network equipment may configure the spatial relationship information set for a specific cell among the cells of the terminal equipment, and the spatial relationship information on each cell may be selected from the spatial relationship information set arranged on the specific cell. This eliminates the need for the network equipment to configure the QCL information and the spatial relationship information for the channel or reference signal on each BWP on each cell independently, and can reduce upper layer signaling overhead.

[0117] For example, when the information for the network device to arrange the QCL information set and the spatial relationship information set does not include a cell index, the QCL information set and the spatial relationship information set are considered to be a shared QCL information set and a shared spatial relationship information set for all cells among at least one cell. When the information for the network device to arrange the QCL information set and the spatial relationship information set includes a cell index, the QCL information set and the spatial relationship information set are considered to be arranged for the cell corresponding to the cell index.

[0118] Optionally, in some embodiments, when the at least one cell is a plurality of cells, the plurality of cells are located within the same frequency band.

[0119] Specifically, in some embodiments, in S420, determining QCL information of downlink channels or downlink reference signals on at least one cell includes determining QCL information of downlink channels or downlink reference signals on some or all of the bandwidth portions BWP on each cell of the at least one cell. In S420, determining spatial relationship information of uplink channels or uplink reference signals on at least one cell includes determining spatial relationship information of uplink channels or uplink reference signals on some or all of the BWP on each cell of the at least one cell.

[0123] It should be noted that the spatial transmission information set received in S510 includes QCL information or spatial relationship information set. It may be understood that network equipment configures the same spatial transmission information set for downlink and uplink on the cell of terminal equipment.Therefore, network equipment does not need to configure spatial transmission information set for downlink and uplink of terminal equipment respectively, and can reduce upper layer signaling overhead.

The embodiment of the present disclosure does not limit the specific selection method.

[0130] It can be further understood that in S510, if the spatial transmission information set includes a spatial relationship information set, determining the spatial relationship information of the uplink channel or the uplink reference signal of at least one cell according to the spatial transmission information set in S520 may be to select the spatial relationship information for at least one cell from the spatial relationship information set. The embodiment of the present disclosure does not limit the specific selection method.

[0131] Alternatively, in S510, the spatial transmission information set includes a spatial relationship information set, and in S520, the implementation manner of determining the QCL information of the downlink channel or the downlink reference signal of at least one cell according to the spatial transmission information set may be: determining candidate QCL information of the downlink channel or the downlink reference signal of at least one cell according to all source RSs in all spatial relationship information in the spatial relationship information set, and determining the QCL information of the downlink channel or the downlink reference signal of at least one cell from the candidate QCL information; or determining a preset number of spatial relationship information sets from the spatial relationship information set, and determining the QCL information of the downlink channel or the downlink reference signal of at least one cell according to the source RSs in the preset number of spatial relationship information.
