[0002] The design target of a new radio (NR) / 5G system includes large-bandwidth communication in a high frequency band (for example, a frequency band above 6 GHz). When the working frequency becomes higher, the path loss in the transmission process increases, thereby affecting the coverage capability of the high-frequency system. An effective technical solution that can effectively ensure the coverage of the high-frequency NR system is to use multiple beam technology based on a massive multiple-input multiple-output (Massive MIMO) antenna array to improve the coverage capability.

[0027] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings, which are only used for reference and do not limit the embodiments of the present application.
[0028] Before the information processing method provided by the embodiments of the present application is described in detail, the multi-beam system, carrier aggregation (CA) and multi-transmit-receive point (TRP) are described.
[0029] The multi-beam (Multi-beam) system of NR / 5G concentrates the transmission power in a narrow beam (beam) to cover part of the area in the cell in the downlink (downlink), thereby enhancing the coverage of the entire system.
[0030] The traditional network deployment (for example, 3G, 4G / LTE) uses one beam (in the traditional system, the entire concept of beam does not need to be additionally mentioned because there is only one) to cover the entire cell. In an example, as shown in FIG. 1, a traditional network deployment uses one beam to cover the entire cell. Figure 1In the middle, the network uses a relatively wide beam: beam 101 covers the entire cell, and can simultaneously serve the terminal devices: UE1, UE2, UE3, UE4 and UE5 in the cell. Therefore, at each moment, the terminal devices within the cell coverage have the opportunity to obtain the transmission resources allocated by the system.
[0031] In NR, relatively narrow multi-beams are used, so that energy can be concentrated, so that terminal devices far from the cell can also obtain good reception performance.
[0032] A multi-beam system achieves the effect of covering the entire cell through beam sweeping in time, that is, different beams are used at different times to cover different areas, and each beam covers a smaller range. Through time sweeping, multiple beams cover the entire cell. In an example, as shown in Figure 2 The multi-beam system uses 4 different beams: beam 201, beam 202, beam 203 and beam 204 at different times to cover different areas, where beam 201 covers the area corresponding to UE1 at time 1, beam 202 covers the area corresponding to UE2 at time 2, beam 203 covers the area corresponding to UE3 and UE4 at time 3, and beam 204 covers the area corresponding to UE5 at time 4. The terminal devices in the cell can only communicate with the network device when a certain beam covers the area corresponding to the terminal device at a certain time. For example, at time 3, the system uses beam 3 to cover UE3 and UE4, and UE3 and UE4 can communicate with the communication device.
[0033] In the above description, the case of using multiple transmit beams for downlink is introduced. Similarly, the terminal device can also use multiple transmit beams for uplink transmission. The principle is similar and will not be repeated here.
[0034] Beam is a term used in daily discussions. In actual protocols, the word beam is often invisible. Different beams are identified or indicated by different signals carried, for example:
[0035] • Different beams transmit different synchronization signals (SS) / physical broadcast channel (PBCH) blocks; terminal devices can distinguish downlink transmit beams by different SS / PBCH blocks.
[0036] • Different beams transmit different Channel state information reference signal (CSI-RS) signals corresponding to different CSI-RS resources; the terminal device distinguishes the downlink transmission beams through the CSI-RS signals / CSI-RS resources.
[0037] • Different beams transmit different Sounding Reference Signal (SRS) signals corresponding to different SRS resources; the network device distinguishes the uplink transmission beams through the SRS signals / SRS resources.
[0038] • When there is beam correspondence (here, it refers to the beam correspondence that does not require uplink beam sweeping (UL beam sweeping), that is, if the reception beam X is the preferred / best choice for receiving a downlink signal, the terminal device infers that the corresponding transmission beam Y is the preferred / best uplink transmission beam according to the reception beam X) at the terminal device side, if the network device indicates that the corresponding downlink signal of a certain downlink transmission beam is a downlink signal A, the terminal device can know the corresponding transmission beam C according to the reception beam B corresponding to the reception downlink signal A. In this case, the network device indicates the uplink transmission beam C of the terminal device, which can often be indirectly indicated by directly indicating the downlink signal A.
[0039] Therefore, the description of the beam is based on the carried uplink signal or downlink signal.
[0040] Among them, the beam correspondence includes two kinds:
[0041] The first kind is the beam correspondence without UL beam sweeping.
[0042] The second kind is the beam correspondence with UL beam sweeping.
[0043] In the embodiments of the present application, the first kind is simply referred to as beam correspondence; when referring to the second kind, it is explicitly stated that it is the beam correspondence with UL beam sweeping, or simply referred to as the beam correspondence is not ideal or does not meet the beam correspondence.
[0044] If there are multiple uplink transmission beams in the terminal device, the network device can determine which uplink transmission beam is used by the terminal device in the following ways:
[0045] Manner one, the network device configures multiple SRS resources, and lets the terminal device use different uplink transmission beams to transmit corresponding SRSs, wherein different uplink transmission beams transmit different SRS resources corresponding SRS signals. The network device can know which uplink transmission beam has better transmission effect by measuring the SRS signals.
[0046] Manner two, if the terminal device side has beam correspondence, the network device considers that the terminal device can know its corresponding receiving beam according to its corresponding better downlink transmission beam according to this feature, and knows the better uplink transmission beam corresponding to the terminal device according to the beam correspondence.
[0047] Among them, manner one can be used in the case of beam correspondence (that is, UL beam sweeping is not required to meet beam correspondence) and the case of non-ideal beam correspondence (that is, UL beam sweeping is required to meet beam correspondence), and manner two is generally used only in the case of beam correspondence.
[0048] When the network device indicates which uplink transmission beam the terminal device uses, it can indirectly indicate the corresponding uplink transmission beam by indicating the following identifiers:
[0049] SRS resource indication identifier (SRS resource indicator, SRI), (optionally, part of the signaling also contains) SRS resource corresponding indication information of the uplink bandwidth part (Bandwidth Part, BWP) identifier (BWP ID).
[0050] Synchronization signal block (Synchronization Signal Block, SSB) index.
[0051] CSI-RS resource identifier.
[0052] Among them, SSB is also SS / PBCH block.
[0053] Here, when describing the uplink transmission beam, it can be embodied by a spatial domain transmission filter. For example: when transmitting SRS, the uplink signal is described as follows:
[0054] If the terminal device is configured with high-layer parameter spatial relationship information including the reference SSB index identifier, the terminal device will use the same spatial domain filter as the received reference SSB to transmit the target SRS resource.
[0055] If the higher layer parameter spatial relation information includes the identification of the reference periodic CSI-RS, the terminal device will use the same spatial domain filter as receiving the reference periodic CSI-RS to transmit the target SRS resource.
[0056] If the higher layer parameter spatial relation information includes the identification of the reference SRS, the terminal device will use the same spatial domain transmission filter as transmitting the reference periodic SRS to transmit the target SRS resource.
[0057] For uplink signals, the transmitted signals and channels can include: SRS, Physical Uplink Shared Channel (PUSCH) or Physical Uplink Control Channel (PUCCH).
[0058] For the transmission of Physical Uplink Shared Channel (PUSCH), it includes: dynamically scheduled PUSCH and semi-persistent scheduled PUSCH.
[0059] Dynamically scheduled PUSCH:
[0060] If the network device only configures one SRS resource for indicating the uplink transmission beam, the UE determines which uplink transmission beam to use according to the information configured by the network device (for example, the corresponding Radio Resource Control (RRC) signaling).
[0061] If the network device configures multiple (currently the protocol supports a maximum of 2) SRS resources for indicating the uplink transmission beam, the UE determines which uplink transmission beam to use according to the information configured by the network device (for example, the corresponding RRC signaling) and the SRS resource indicated by the Downlink control information (DCI).
[0062] Semi-persistent scheduled PUSCH:
[0063] If the parameter rrc-ConfiguredUplinkGrant is contained in the RRC message element (Information Element, IE) configuredGrantConfig, the UE determines which uplink transmission beam to use according to the SRS resource identification indicated in the RRC parameter; if the parameter rrc-ConfiguredUplinkGrant is not contained in the RRC IE configuredGrantConfig, the UE determines which uplink transmission beam to use according to the SRS resource indicated by the DCI indication information.
[0064] For SRS transmission: indicated by the parameter SRS spatial relation information (SRS-SpatialRelationInfo).
[0065] The network device configures SRS-SpatialRelationInfo for SRS resource, where SRS-SpatialRelationInfo can indicate any of the following three information: SRI (optionally, containing the indication information corresponding to the uplink BWP ID where the SRS resource is located at the same time), SSB index and CSI-RS resource identification.
[0066] For physical uplink control channel (Physical Uplink Control CHannel, PUCCH) transmission: indicated by the parameter PUCCH-SpatialRelationInfo.
[0067] The network device configures PUCCH-SpatialRelationInfo (spatial relation information) for PUCCH, which can indicate any of the following three information: SRI (optionally, containing the indication information corresponding to the uplink BWP ID where the SRS resource is located at the same time), SSB index and CSI-RS resource identification.
[0068] If the network configures one PUCCH-SpatialRelationInfo for PUCCH, all PUCCH resources determine which uplink transmission beam to use according to the information configured by the network device.
[0069] If the network configures multiple PUCCH-SpatialRelationInfo for PUCCH, each PUCCH resource determines which uplink transmission beam to use according to the spatial relation information indicated / configured / activated by the network device (such as MAC CE).
[0070] In the following description, the spatial relation information can refer to PUCCH spatial relation information, and / or SRS spatial relation information.
[0071] In the following description, if only the description on the carrier is mentioned, and the description content is related to BWP, if not specifically stated for BWP, it is generally defaulted to the current active BWP on the carrier.
[0072] In actual network applications, if the spatial relation information (SRS-SpatialRelationInfo or PUCCH-SpatialRelationInfo) is configured for both SRS and PUCCH, there will be a large signaling overhead in some scenarios.
[0073] To meet the demand for high-rate services, CA technology is supported in 5G. CA is to combine scheduling and use resources on multiple component carriers (CCs) so that the 5G system can support a larger bandwidth, thereby enabling higher system peak rates. According to the continuity of the aggregated carriers in the frequency spectrum, it can be divided into Figure 3 non-continuous carrier aggregation shown in 301 and Figure 3 continuous carrier aggregation shown in 302; according to whether the frequency bands of the aggregated carriers are the same, it can be divided into inter-band carrier aggregation and intra-band carrier aggregation. Among them, Figure 3 in 301, two discontinuous component carriers (component carrier A and component carrier B) are aggregated, the bandwidth of one component carrier is 20MHz, and the total bandwidth after carrier aggregation is 40MHz; in Figure 3 in 302, five consecutive carriers are aggregated, the bandwidth of one component carrier is 20MHz, and the total bandwidth after carrier aggregation is 100MHz.
[0074] Generally, the target downlink signal (or target downlink channel) and its reference SSB or reference CSI-RS resource are transmitted by the same transmit-receive point (TRP) at the network side. If the TRPs transmitting the two downlink signals are different, different TCI states are usually configured. The network structure including multiple TRPs can be as shown in Figure 4 , the UE communicates with TRP1 and TRP2 through beam 401 and beam 402 respectively.
[0075] Here, the TCI state is used to configure the quasi-co-location relationship between one or two downlink reference signals and the DMRS of PDSCH.
[0076] The description of QCL is as follows: the large-scale parameters of the channel on one antenna port can be derived from another antenna port, and then the two antenna ports are considered to have a QCL relationship, and the large-scale parameters include: Doppler delay, average delay, spatial reception parameters, etc. That is, when two SSBs have a QCL relationship, it can be considered that the large-scale parameters (such as Doppler delay, average delay, spatial reception parameters, etc.) of the two SSBs can be inferred from each other, or can be considered to be similar.
[0077] If the network device configures the QCL reference signal of the target downlink signal as a reference SSB or a reference CSI-RS resource through the TCI state, and the QCL type configuration is type A, type B or type C, the terminal can assume that the large-scale parameters of the target downlink signal and the reference SSB or the reference CSI-RS resource are the same, and the large-scale parameters are determined by the QCL type configuration.
[0078] If the network device configures the QCL reference signal of the target downlink signal as a reference SSB or a reference CSI-RS resource through the TCI state, and the QCL type configuration is type D, the terminal device can use the same receive beam or spatial reception parameter (Spatial Rx parameter) as receiving the reference SSB or the reference CSI-RS resource to receive the target downlink signal.
[0079] Therefore, how the terminal device determines the uplink transmission beam for transmitting the uplink signal when the network device does not configure the spatial relationship information becomes a problem to be solved, and the determination of the spatial relationship information in the scenarios of multiple component carriers (CCs), CA, multiple TRPs, etc. is not involved.
[0080] Based on the above problems, the embodiments of the present application provide an information processing method, and the information processing method of the embodiments of the present application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), 5G system or future communication system, etc.

[0090] An optional processing flow of the information processing method provided by the embodiments of the present application is shown in Figure 6 The method includes the following steps:
[0091] S601, when the first uplink signal is not configured with spatial relationship information, the terminal device determines a first spatial domain transmission filter used for transmitting the first uplink signal according to a first CC where the first uplink signal is located or a first downlink BWP corresponding to the first CC, or determines the first spatial domain transmission filter according to a path loss reference signal corresponding to the first uplink signal.
[0092] Optionally, when there is no corresponding activated TCI state on the PDSCH on the first CC or the first downlink BWP, or at least one CORESET configured on the first CC or the first downlink BWP corresponding to the first CC is configured with a corresponding group index, the first spatial domain transmission filter is determined according to the path loss reference signal corresponding to the first uplink signal.
[0093] In the embodiments of the present application, the first uplink signal or the first uplink channel and the resource carrying the first uplink signal or the first uplink channel are referred to as the first uplink signal.
[0094] Optionally, the signal / channel type of the first uplink signal includes at least one of the following: SRS (or SRS resource corresponding to SRS) and PUCCH (or PUCCH resource corresponding to PUCCH).
[0095] For example, the first uplink signal is SRS, and the first spatial domain transmission filter is used for transmitting SRS on the first SRS resource.
[0096] Optionally, the transmission scenario of the first uplink signal is a single-TRP scenario.
[0097] For example, the transmission scenario of the first uplink signal is a single-TRP scenario, and the terminal device determines the first spatial domain transmission filter used for transmitting the first uplink signal according to the first CC where the first uplink signal is located or a first downlink BWP corresponding to the first CC, including:
[0098] When the first CC where the first uplink signal is located or the first downlink BWP is not configured with a control resource set (CORESET), the first spatial domain transmission filter is determined according to a first transmission configuration indication (TCI) state in TCI states corresponding to a physical downlink shared channel (PDSCH) on the first CC or the first downlink BWP.
[0099] Optionally, the first TCI state is an activated TCI state.
[0100] In an example, the first TCI state is an activated TCI state, and the first TCI state is the smallest TCI state in the activated TCI states.
[0101] In the embodiment of the application, the first TCI state is selected from TCI states corresponding to the PDCCH according to the first selection rule, the first selection rule can be other rules such as identifying the maximum, identifying a fixed value in addition to identifying the minimum, and the first TCI state selected according to the first selection rule includes one or more TCI states.

[0103] Optionally, the PDSCH on the first CC or the first downlink BWP has a corresponding activated TCI state.
[0104] Here, when the PDSCH on the first CC or the first downlink BWP has a corresponding TCI state, and the corresponding TCI state has an activated TCI state, the first spatial domain transmission filter is determined using the TCI state with the smallest ID in the activated TCI state.
[0105] Optionally, before S601, when the PDSCH on the first CC or the first downlink BWP does not have a corresponding activated TCI state, the method further includes:
[0106] S600A, the terminal device receives indication information sent by the network device.
[0107] The indication information is used to activate at least one TCI state in the TCI state corresponding to the PDSCH on the first CC or the first downlink BWP.
[0108] Optionally, the indication information can be transmitted through a MAC CE.
[0109] At this time, the first TCI state is the activated TCI state.
[0110] Here, when the PDSCH on the first CC or the first downlink BWP has a corresponding TCI state, and the corresponding TCI state does not have an activated TCI state, the network device activates the existing TCI state, and the first spatial domain transmission filter is determined using the TCI state with the smallest ID in the currently activated TCI state.

[0113] 2. The PDSCH on the first CC or the first downlink BWP does not have a corresponding activated TCI state.
[0114] Here, if the first uplink signal is not configured with spatial relationship information, and the first CC or the first downlink BWP where the first uplink signal is located is not configured with a control resource set CORESET, the UE does not expect the PDSCH on the first CC or the first downlink BWP to not have a corresponding activated TCI state.
[0115] Optionally, when the PDSCH on the first CC or the first downlink BWP does not have a corresponding activated TCI state, the terminal device determines the first spatial domain transmission filter according to the path loss reference signal corresponding to the first uplink signal.
[0116] Optionally, when there is a corresponding TCI state for the PDSCH on the first CC or the first downlink BWP, and there is no activated TCI state in the corresponding TCI state, a first spatial domain transmission filter is determined using a path loss reference signal.
[0117] Optionally, the path loss reference signal can correspond to a CSI-RS resource, or an SS / PBCH block, or a positioning RS (PRS) resource.
[0118] Optionally, when there is no corresponding activated TCI state for the PDSCH on the first CC or the first downlink BWP, the first TCI state is the TCI state with the smallest ID in the corresponding TCI state of the PDSCH.
[0119] Here, when there is a corresponding TCI state for the PDSCH on the first CC or the first downlink BWP, and there is no activated TCI state in the corresponding TCI state, a first spatial domain transmission filter is determined using the TCI state with the smallest ID in the existing TCI state.

[0121] S600B, the terminal device receives the TCI state corresponding to the PDSCH configured by the network device.
[0122] At this time, the first TCI state is the TCI state with the smallest ID in the configured TCI state.
[0123] Here, when there is no corresponding TCI state for the PDSCH on the first CC or the first downlink BWP, a TCI state is configured by the network device, and a first spatial domain transmission filter is determined using the TCI state with the smallest ID in the configured TCI state.
[0124] Taking a multi-TRP scenario as an example for the transmission scenario of the first uplink signal (if not specified, the first uplink signal is not configured with corresponding spatial relationship information), the terminal device determines a first spatial domain transmission filter used for transmitting the first uplink signal according to the first CC where the first uplink signal is located or the first downlink BWP corresponding to the first CC, including:
[0125] The first spatial domain transmission filter is determined according to a first CORESET corresponding TCI state or a first CORESET corresponding QCL signal when at least one CORESET corresponding group index is configured in the CORESET configured on the first CC or the first downlink BWP corresponding to the first uplink signal.
[0126] The first spatial domain transmission filter is determined according to the first spatial relationship information corresponding to the first uplink signal when at least one CORESET corresponding group index is configured in the CORESET configured on the first CC or the first downlink BWP corresponding to the first uplink signal. Or, the terminal hopes that the first uplink signal is configured with corresponding first spatial relationship information when at least one CORESET corresponding group index is configured in the CORESET configured on the first CC or the first downlink BWP corresponding to the first uplink signal.
[0127] In the embodiment of the application, the first CORESET is selected from the CORESET configured on the first CC or the first downlink BWP according to the second selection rule. In addition to identifying the minimum, the second selection rule can also identify the maximum, identify a fixed value, and other rules, and the first CORESET selected according to the second selection rule includes one or more CORESETs. The content of the second selection rule can be predefined or configured by the network device, and the embodiment of the application does not limit the content of the second selection rule.
[0128] Here, the transmission scenario of the first uplink signal is a multi-TRP scenario, which can be embodied by at least one CORESET corresponding group index configured in the CORESET configured on the first CC or the first downlink BWP corresponding to the first uplink signal. One group index can correspond to one TRP.
[0129] Optionally, the group index is configured in the RRC configuration parameter corresponding to the at least one CORESET.
[0130] Optionally, the group indexes configured by different CORESETs can be the same or different.
[0131] In the embodiment of the application, the CORESETs configured with the same group index can be referred to as a CORESET group. In an example, the value of the group index includes 0 and 1, and the CORESET with the group index value of 0 is a CORESET group, and the CORESET with the group index value of 1 is another CORESET group.
[0132] In the embodiments of the present application, when at least one CORESET is configured with a group index, the CORESETs not configured with a group index are considered to have a fixed value (for example, 0 or 1) or a different value from the configured group index as the value of the group index.
[0133] In the embodiments of the present application, the group index can be used to determine a hybrid automatic repeat request response (HARQ-ACK) codebook (Codebook). That is, according to network-related configuration parameters, the HARQ-ACK of the PDSCH scheduled by the CORESETs with different group indexes can use independent HARQ-ACK Codebooks.
[0134] Alternatively, the terminal device can be configured by network-related configuration parameters that the HARQ-ACK of the PDSCH scheduled by the CORESETs with different group indexes can be a joint HARQ-ACK Codebook. At this time, the CORESETs with different group indexes use the same HARQ-ACK Codebook.

[0150] Here, when at least one of the first CC where the first uplink signal is located or the first downlink BWP corresponding to the first CC is configured with a CORESET corresponding to the group index, the terminal device does not expect not to be configured with the first spatial relation information. The terminal device receives the first spatial relation information configured by the network device.

[0163] The first spatial domain transmission filter and the second spatial domain transmission filter are determined according to the number of the first CC and the number of the second CC.
[0164] For example, the first spatial domain transmission filter and the second spatial domain transmission filter are determined according to the second spatial relation information.
[0165] Optionally, the terminal device determines the first spatial domain transmission filter and the second spatial domain transmission filter according to the second spatial relation information on the overlapping symbol in which the first uplink signal and the second uplink signal overlap in the time domain.
[0166] The first uplink signal and the second uplink signal overlap in the time domain in the manners as shown in Figure 8 The manners include partial overlap as shown in 801, inclusion as shown in 802, and complete overlap as shown in 803.
[0167] For example, the first spatial domain transmission filter and the second spatial domain transmission filter are determined according to the signal parameters of the first uplink signal and the signal parameters of the second uplink signal to determine the priority of the first uplink signal and the second uplink signal, and then determine the priority of the first spatial domain transmission filter and the second spatial domain transmission filter, and finally determine the first spatial domain transmission filter and the second spatial domain transmission filter according to the priority of the first spatial domain transmission filter and the second spatial domain transmission filter.
[0168] Optionally, the terminal device determines the first spatial domain transmission filter and the second spatial domain transmission filter according to the signal parameters of the first uplink signal and the signal parameters of the second uplink signal on the overlapping symbol in which the first uplink signal and the second uplink signal overlap in the time domain.
[0169] The signal parameter comprises at least one of the following: signal / channel type, signal time domain characteristic.
[0170] In an example, the signal / channel type comprises: SRS, PUCCH and PUSCH.
[0171] In an example, the signal time domain characteristic comprises: periodicity, aperiodicity and semi-persistence.
[0172] In the embodiment of the application, the rule for determining the priority of the signal parameter of the first uplink signal and the signal parameter of the second uplink signal can be set according to actual needs. In an example, the priority of SRS is higher than the priority of PUCCH (SRS>PUCCH). In an example, PUCCH<SRS. In an example, aperiodic SRS>periodic or semi-persistent SRS.
[0173] Optionally, the signal parameter can also comprise: carried content. In an example, PUCCH carrying HARQ / SR>SRS.
[0174] Taking SRS>PUCCH as an example, the first uplink signal is SRS, and the second uplink signal is PUCCH, so the priority of the first uplink signal is higher than that of the second uplink signal.
[0175] Taking SRS<PUCCH as an example, the first uplink signal is SRS, and the second uplink signal is PUCCH, so the priority of the second uplink signal is higher than that of the first uplink signal.
[0176] Optionally, the determination manner of the first spatial domain transmission filter and the second spatial domain transmission filter comprises:
[0177] determining the spatial domain transmission filter with high priority from the first spatial domain transmission filter and the second spatial domain transmission filter, and the spatial domain transmission filter with low priority is the same as the spatial domain transmission filter with high priority, wherein the spatial domain transmission filter with high priority is the spatial domain transmission filter used by the uplink signal with high priority of the signal parameter in the first spatial domain transmission filter and the second spatial domain transmission filter, and the spatial domain transmission filter with low priority is the spatial domain transmission filter used by the uplink signal with low priority of the signal parameter in the first spatial domain transmission filter and the second spatial domain transmission filter.

[0181] In the embodiment of the present application, the spatial domain transmission filter with a higher priority is the spatial domain transmission filter of the uplink signal with a higher priority of the transmission signal parameter.
[0182] In an example, the signal parameter of the first uplink signal has a higher priority than the signal parameter of the second uplink signal, and the first spatial domain transmission filter has a higher priority than the second spatial domain transmission filter.
[0183] Optionally, the signal parameter further comprises: a number of the CC. When the priority of the first uplink signal and the second uplink signal is determined according to one or more of the signal / channel type or the signal time domain feature, the priority of the first uplink signal and the second uplink signal is determined according to the number of the first CC and the number of the second CC.
[0184] In an example, the uplink signal with a larger number of the CC has a higher priority. In an example, the uplink signal with a smaller number of the CC has a higher priority.
[0185] Taking the determination of the first spatial domain transmission filter and the second spatial domain transmission filter by way of the third way as an example, the first spatial domain transmission filter and the second spatial domain transmission filter are determined according to the number of the first CC and the number of the second CC.
[0186] Optionally, when the number of the first CC is smaller than the number of the second CC, the first spatial domain transmission filter is determined, and the second spatial domain transmission filter is the same as the first spatial domain transmission filter, and the spatial domain transmission filter with a larger number of the corresponding CC follows the spatial domain transmission filter with a smaller number of the corresponding CC.
[0187] Optionally, when the number of the first CC is greater than the number of the second CC, the first spatial domain transmission filter is determined, and the second spatial domain transmission filter is the same as the first spatial domain transmission filter. At this time, the spatial domain transmission filter corresponding to the CC with the smaller number follows the spatial domain transmission filter corresponding to the CC with the greater number.
[0188] In the embodiments of the present application, taking the case that the first spatial domain transmission filter follows the second spatial domain transmission filter as an example, in the case that the second uplink signal is configured with the second spatial relationship information, the second spatial domain transmission filter is determined according to the second spatial relationship information; in the case that the second uplink signal is not configured with the second spatial relationship information, the second spatial domain transmission filter can be determined according to the information processing method shown in Figure 6 Taking the case that the second spatial domain transmission filter follows the first spatial domain transmission filter as an example, the first spatial domain transmission filter can be determined according to the information processing method shown in Figure 6

[0200] The first CC and the second CC belong to intra-band carrier aggregation.
[0201] The first CC and the second CC are in the same CC group.
[0202] The first CC and the second CC are determined according to the reporting capability of the terminal device.

In the CA scenario or the multi-TRP scenario and when the network device is not configured with spatial relationship information, the uplink transmission beam for transmitting the uplink signal is determined.
[0204] In the following, the information processing method provided by the embodiment of the application is exemplarily described by taking the first uplink signal as an SRS and through different examples.
[0205] Example 1: Single-TRP scenario
[0206] The terminal device transmits the first SRS resource by using a first spatial domain transmission filter, wherein the first SRS resource is not configured with corresponding spatial relationship information.
[0207] Optionally, the frequency band used for transmitting the first SRS resource is a millimeter wave frequency band.
[0208] Optionally, the SRS resource set corresponding to the first SRS resource is used to support codebook transmission.
[0209] Optionally, the usage of the SRS resource set corresponding to the first SRS resource is codebook.
[0210] Optionally, the SRS resource set corresponding to the first SRS resource is used to support non-codebook transmission.
[0211] Optionally, the usage of the SRS resource set corresponding to the first SRS resource is nonCodebook.
[0212] Optionally, the SRS resource set corresponding to the first SRS resource is used for supporting antenna switching.

[0215] Optionally, usage of the SRS resource set corresponding to the first SRS resource is positioning.
[0216] Optionally, the terminal device satisfies beam correspondence.
[0217] Optionally, the first SRS resource can be aperiodic, or periodic, or semi-persistent.
[0218] In a single-TRP scenario, the manner in which the terminal device determines the first spatial domain transmission filter comprises:
[0219] Manner A1, when the first CC or the first BWP where the first SRS resource is located is configured with one or more CORESETs, the terminal device determines the first spatial domain transmission filter according to a reference signal corresponding to a type D ('QCL-TypeD') in a TCI-state corresponding to a first CORESET or a reference signal corresponding to a type D ('QCL-TypeD') in corresponding QCL information.
[0220] In manner A1, optionally, the first CORESET is a CORESET with the smallest ID among CORESETs detected by the terminal device on a latest downlink slot on the first CC or the first BWP.
[0221] In manner A1, optionally, when the first SRS resource is aperiodic, the first CORESET is a CORESET corresponding to a DCI triggering transmission of the first SRS resource.
[0222] Manner A2, when the first CC or the first BWP where the first SRS resource is located is not configured with a CORESET, the terminal device determines the first spatial domain transmission filter according to a reference signal corresponding to a type D ('QCL-TypeD') in a TCI state with the smallest ID among activated TCI states corresponding to PDSCH on the first CC or the first BWP.
[0223] A3, when the first SRS resource is located in the first CC or the first BWP which does not configure CORESET, and there is no activated TCI state corresponding to PDSCH on the first CC or the first BWP, at least one TCI state corresponding to PDSCH on the first CC or the first BWP must be activated, and the terminal device determines the first spatial domain transmission filter based on the activated TCI state.
[0224] In the A3, when the first SRS resource is located in the first CC or the first BWP which does not configure CORESET, and there is no activated TCI state corresponding to PDSCH on the first CC or the first BWP, the first SRS resource needs to be configured with corresponding spatial relationship information.
[0225] For the A3, the number of possible cases can be reduced, the protocol complexity can be reduced, and the UE and network implementation complexity can be reduced by limiting the network configuration.
[0226] A4, when the first SRS resource is located in the first CC or the first BWP which does not configure CORESET, and there is no activated TCI state corresponding to PDSCH on the first CC or the first BWP, the terminal device determines the first spatial domain transmission filter according to the reference signal corresponding to the type D ('QCL-TypeD') in one of the TCI states configured for PDSCH on the first CC or the first BWP. Optionally, the one TCI state is the TCI state corresponding to the PDSCH identified as the smallest TCI state.
[0227] The A4 does not need to be an activated TCI state compared with the A3, and the signaling of activating the PDSCH TCI state can be saved.
[0228] A5, when the first SRS resource is located in the first CC or the first BWP which does not configure CORESET, and at least one TCI state corresponding to PDSCH is not configured on the first CC or the first BWP, at least one TCI state corresponding to PDSCH is configured on the first CC or the first BWP, and the terminal device determines the first spatial domain transmission filter through the configured TCI state.
[0229] In the A5, when the first SRS resource is located in the first CC or the first BWP which does not configure CORESET, and there is no TCI state corresponding to PDSCH configured on the first CC or the first BWP, the first SRS resource needs to be configured with corresponding spatial relationship information.
[0230] The manner A5 can reduce the number of possible cases, reduce the protocol complexity, and reduce the implementation complexity of the UE and the network by limiting the network configuration.
[0231] In the manner A6, when the first CC or the first BWP where the first SRS resource is located is not configured with a CORESET, and there is no activated TCI state corresponding to the PDSCH on the first CC or the first BWP, the terminal device determines the first spatial domain transmission filter according to a path loss reference signal (Pathloss RS) corresponding to the first SRS resource.
[0232] Based on the manner A6, the existing path loss reference signal is used to reduce the implementation complexity of the terminal device in determining the first spatial domain transmission filter.
[0233] In the manner A6, optionally, the first spatial domain transmission filter is the same as the spatial domain filter used for receiving the path loss reference signal.
[0234] In the manner A6, optionally, the path loss reference signal includes one of the following resources: a CSI-RS resource, an SS / PBCH block, and a positioning RS (PRS) resource.

[0238] Optionally, the second uplink signal can be an SRS signal or a positioning reference signal.
[0239] Optionally, the second channel can be a PDSCH or a PDCCH.
[0240] Optionally, the first CC and the second CC are two different CCs, and belong to two different CCs in the carrier aggregation.
[0241] Optionally, the first BWP and the second BWP are BWPs on two different CCs in the carrier aggregation, respectively.

[0263] If the second uplink signal is PUCCH or PUSCH, the UE determines the first spatial domain transmission filter according to the second spatial domain transmission filter of the second uplink signal. Here, the second spatial domain transmission filter corresponding to the PUCCH or PUSCH is determined according to the spatial relation information corresponding to the second uplink signal, and then the SRS adopts the same spatial domain transmission filter as the first spatial domain transmission filter.

[0271] Optionally, if the second uplink signal is SRS, the first spatial domain transmission filter and the second spatial domain transmission filter are determined by mode B4.
[0272] Mode B4, if the second uplink signal (or the second channel) is not configured with corresponding spatial relation information, if the transmission of the first SRS resource and the second uplink signal (or the second channel) overlaps in the time domain, the first spatial domain transmission filter and the second spatial domain transmission filter are determined according to the information of the first CC and the second CC, or only in the overlapping symbol, the first spatial domain transmission filter and the second spatial domain transmission filter are determined according to the information of the first CC and the second CC.
[0273] In mode B4, the rules between the spatial filters corresponding to multiple CCs are explicitly defined to avoid the uncertainty of the behavior of the terminal device and improve the system performance.
[0274] In the manner B4, optionally, if the number of the first CC is smaller than the number of the second CC, the first spatial domain transmission filter is determined, and the second spatial domain transmission filter adopts the same filter as the first spatial domain transmission filter.

[0276] Here, the first spatial domain transmission filter can be determined by the method provided in the embodiment one.
[0277] The manner B5, the first spatial domain transmission filter and the second spatial domain transmission filter are the same. Here, the terminal device does not expect the first spatial domain transmission filter and the second spatial domain transmission filter to be different.
[0278] The manner B5 can avoid that the UE has to use two different uplink transmission beams, and reduce the UE implementation complexity.
[0279] If the first spatial domain transmission filter and the second spatial domain transmission filter are different, the transmission manner of the terminal device sending the signal includes:
[0280] The transmission manner 1, the terminal device decides which signal or channel to send by itself, and thus sends one uplink signal or channel through one spatial domain transmission filter.
[0281] The transmission manner 1 can avoid that the UE has to use two different uplink transmission beams, and reduce the UE implementation complexity.
[0282] The transmission manner 2, the terminal device decides which signal or channel to send according to the priority of the first SRS and the second uplink signal.
[0283] For the transmission manner 2, optionally, the priority of the first SRS and the second uplink signal is determined according to the type of the channel or signal. Optionally, SRS < PUCCH. Optionally, SRS > PUCCH. Optionally, SRS < PUSCH. Optionally, SRS > PUSCH.
[0284] Here, the priority can also include the priority in the manner B2 or the manner B3.
[0285] For the transmission manner 2, optionally, the priority of the first SRS and the second uplink signal is determined according to the CC where the signal or channel is located. Optionally, if the number of the first CC is smaller than the number of the second CC, the first SRS resource is sent. Optionally, if the number of the first CC is greater than the number of the second CC, the first SRS resource is sent.
[0286] In the embodiments of the present application, the relationship satisfied by the first CC and the second CC includes one of the following relationships:
[0287] Relationship 1: The first CC and the second CC (or the CC corresponding to the first BWP and the CC corresponding to the second BWP) are intra-band.
[0288] At this time, the first CC and the second CC can match typical hardware implementation, reducing the UE implementation complexity.
[0289] Relationship 2: The first CC and the second CC (or the CC corresponding to the first BWP and the CC corresponding to the second BWP) are in the same CC group configured by the network.
[0290] At this time, the network device can flexibly control which CCs use the same UL beam, increasing network flexibility.
[0291] Optionally, if the CCs in the CC group are simultaneously transmitted, the same spatial domain transmission filter is used.
[0292] Relationship 3: The first CC and the second CC (or the CC corresponding to the first BWP and the CC corresponding to the second BWP) are determined according to the UE reported capability.
[0293] Optionally, the UE reported capability indicates which frequency or frequency band uses the same spatial domain transmission filter if simultaneously transmitted. Here, the first CC and the second CC can match the UE reported capability, reducing the UE implementation complexity.
[0294] Example three, multi-TRP scenario
[0295] When the CORESET on the first CC or the first BWP where the first SRS resource is located is configured with a corresponding group index value.
[0296] Optionally, the group index is configured in the RRC configuration parameter of the CORESET (such as the RRC parameter ControlResourceSet). The group indexes configured by different CORESETs can be the same or different. Optionally, the CORESETs configured with the same index can be referred to as a CORESET group. For example, the CORESET with an index value of 0 is a CORESET group, and the CORESET with an index value of 1 is another CORESET group.
[0297] Optionally, the value of the group index is 0 or 1.
[0298] Optionally, if the group index is not configured, a fixed value can be used by default, such as 0 or 1.
[0299] Optionally, the group index can be used to determine the HARQ-ACK codebook, that is, according to the relevant information configured by the network, the HARQ-ACK of the PDSCH scheduled by the CORESET with different group indexes can adopt independent HARQ-ACK codebooks.
[0300] When the CORESET on the first CC or the first BWP where the first SRS resource is located is configured with a corresponding group index value, the terminal device determines the first spatial domain transmission filter in the following manner:
[0301] C1, according to the reference signal corresponding to the type D ('QCL-TypeD') in the TCI-state (TCI state) corresponding to the first CORESET or the reference signal corresponding to the type D ('QCL-TypeD') in the corresponding QCL information, to determine the first spatial domain transmission filter.
[0302] C2, the network configures the terminal device to adopt joint HARQ-ACK feedback (that is, the HARQ-ACK corresponding to the downlink data sent by different TRPs can be multiplexed and fed back together, which is generally only applicable to the case where the backhaul between different TRPs is relatively ideal), and the terminal device determines the first spatial domain transmission filter according to the reference signal corresponding to the type D ('QCL-TypeD') in the TCI-state (TCI state) corresponding to the second CORESET or the reference signal corresponding to the type D ('QCL-TypeD') in the corresponding QCL information.
[0303] In mode C2, optionally, the second CORESET is the CORESET with the smallest ID among the CORESETs corresponding to the first group index on the downlink slot most recently detected by the terminal device on the first CC or the first BWP. At this time, different TRPs can be selected for transmission at different times, and diversity effect can be obtained. Optionally, the first group index is 0 or 1.
[0304] In mode C2, optionally, the second CORESET is the CORESET with the smallest ID among the CORESETs corresponding to all group indexes on the downlink slot most recently detected by the terminal device on the first CC or the first BWP. At this time, the terminal device always selects a fixed TRP for transmission to achieve simplicity and reduce the implementation complexity of the UE and the network.
[0305] Optionally, the terminal device determines, according to a network indication, whether the second CORESET is a CORESET with a minimum ID among CORESETs corresponding to all group indexes on a latest detected downlink slot of the terminal device on the first CC or the first BWP, or a CORESET with a minimum ID among CORESETs corresponding to a first group index on the latest detected downlink slot of the terminal device on the first CC or the first BWP.
[0306] In the manner C2, optionally, if the first SRS resource transmission is first DCI triggered, the second CORESET is a CORESET carrying the first DCI. Here, if the first SRS resource is replaced by a first PUCCH resource, if the first PUCCH resource transmission is first DCI triggered, or the carried information corresponds to data scheduled by the first DCI.
[0307] The manner C3, the network configures the terminal device to use separate HARQ-ACK feedback (HARQ-ACK corresponding to downlink data sent by different TRPs can be fed back separately, and not multiplexed together, which is generally applicable to the case that the backhaul between different TRPs is not ideal, and can also be applicable to the case that the backhaul between different TRPs is relatively ideal), and the terminal device determines the first spatial domain transmission filter according to a reference signal corresponding to a type D ('QCL-TypeD') in a TCI-state (TCI state) corresponding to the third CORESET or a reference signal corresponding to the type D ('QCL-TypeD') in corresponding QCL information.
[0308] In the manner C3, optionally, the third CORESET is a CORESET with a minimum ID among CORESETs corresponding to a first group index on a latest detected downlink slot of the terminal device on the first CC or the first BWP. Optionally, the first group index is 0 or 1.
[0309] In the manner C3, optionally, the third CORESET is a CORESET with a minimum ID among CORESETs corresponding to all group indexes on a latest detected downlink slot of the terminal device on the first CC or the first BWP.
[0310] Optionally, the terminal device determines, according to a network indication, whether the third CORESET is a CORESET with a minimum ID among CORESETs corresponding to all group indexes on a latest detected downlink slot of the terminal device on the first CC or the first BWP, or a CORESET with a minimum ID among CORESETs corresponding to a first group index on the latest detected downlink slot of the terminal device on the first CC or the first BWP.
[0311] In the manner C3, optionally, if the first SRS resource transmission is triggered by the first DCI, the third CORESET is the CORESET with the smallest ID among the CORESETs corresponding to the second group of indexes of the downlink time slots most recently detected by the terminal device on the first CC or the first BWP. Here, if the first SRS resource is replaced by the first PUCCH resource, if the first PUCCH resource transmission is triggered by the first DCI, or the information carried corresponds to the data scheduled by the first DCI.
[0312] Optionally, the second group of indexes is the group of indexes corresponding to the CORESET carrying the first DCI.
[0313] In the manner C3, if the first SRS resource transmission is triggered by the first DCI, the third CORESET is the CORESET carrying the first DCI.
[0314] In the manner C3, optionally, the first SRS resource needs to be configured with corresponding spatial relationship information, that is, the UE does not expect the first SRS resource to be configured without spatial relationship information. Here, the network configuration can be limited, the number of possible cases can be reduced, and the implementation complexity of the UE and the network can be reduced.
[0315] The manner C4, the first SRS resource needs to be configured with corresponding spatial relationship information. Here, the UE does not expect the first SRS resource to be configured without spatial relationship information, and in a multi-DCI based multi-TRP system, the default relationship or the default spatial relationship information described above is not allowed, and the implementation complexity of the UE and the network is reduced.
[0316] The manner C5, the terminal device determines the first spatial domain transmission filter according to a path loss reference signal (Pathloss RS) corresponding to the first SRS resource.
[0317] Optionally, the first spatial domain transmission filter is the same as the spatial domain filter used to receive the path loss reference signal.
[0318] Optionally, the path loss reference signal can be a CSI-RS resource, an SS / PBCH block, or a PRS resource.
[0319] It should be noted that the above examples one to three take the first uplink signal as SRS as an example, and in actual application, the first uplink signal can also be PUCCH.
[0320] It should be noted that the first BWP in the above examples one to three is the downlink BWP corresponding to the first CC, and the second BWP is the downlink BWP corresponding to the second CC.
