[0054] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0055] 1. Beam indication mechanism

[0056] In the 5G NR system, after beam measurement and beam reporting, the network-side device can make beam indications for the downlink and uplink channels or reference signals to establish a beam link between the network-side device and the UE to achieve channel or reference signal transmission.

[0057] The beam indication mechanism for CSI-RS is as follows:

[0058] When the CSI-RS type is periodic CSI-RS, the network-side device configures beam information for the CSI-RS resource through Radio Resource Control (RRC) signaling;

[0059] When the CSI-RS type is semi-persistent CSI-RS, the network-side device indicates its beam information when activating the CSI-RS resource from the CSI-RSresource set configured by RRC through a Medium Access Control Control Element (MAC CE) command;

[0060] When the CSI-RS type is aperiodic CSI-RS, the network side device configures beam information for the CSI-RS resource through RRC signaling, and uses downlink control information (Downlink Control Information, DCI) to trigger the CSI-RS.

[0061] Optionally, the beam information mentioned in the present application may also be referred to as: spatial relation information, spatial domain transmission filter information, spatial domain reception filter information, spatial filter information, transmission configuration indicator state (TCI state) information, quasi co-location (QCL) information or QCL parameters, etc. Among them, downlink beam information can usually be represented by TCI state information or QCL information. Uplink beam information can usually be represented by spatial relation information.

[0062] 2. Default beam mechanism for aperiodic CSI-RS.

[0063] In the 5G NR system, the default beam mechanism for aperiodic CSI-RS is defined as follows:

[0064] If the last symbol of the physical downlink control channel (PDCCH) carrying the triggered DCI is equal to the non-zero power 14.1.2 When the scheduling offset between the first symbols of aperiodic CSI-RS resources in a (NZP)-CSI-RS resource set (for which no higher layer parameter trs-Info is configured) is less than the threshold beam switch timing reported by the UE, where the reported value is one of the values ​​{14,28,48} and enableBeamSwitchTiming is not configured, or the scheduling offset is less than 48, where the UE reports beamSwitchTiming-r16, and enableBeamSwitchTiming is configured, and the higher layer parameter repetition is configured to "off" for the NZP-CSI-RS resource set or is not configured with the higher layer parameter repetition, or the scheduling offset is less than the threshold beamSwitchTiming-r16 reported by the UE, where enableBeamSwitchTiming is configured, and the higher layer parameter repetition is configured to "on" for the NZP-CSI-RS resource set, the following behaviors exist:

[0065] If condition 1 is met, the first behavior is executed; wherein condition 1 includes: if the UE is configured with enableDefaultTCI-StatePercoResetPoolidex, and the UE is configured with a higher layer parameter PDCCHConfig, and the ControlResourceSet of the parameter contains two different CoreSetPoolidex values. The first behavior includes:

[0066] If there is any other downlink (DL) signal using the TCI state indicated by the network side device in the same symbol as the CSI-RS, the UE applies the QCL assumption of the other downlink signal to receive the non-periodic CSI-RS. The other DL signal refers to the physical downlink shared channel (PDSCH) scheduled by the PDCCH, and the PDCCH that schedules the PDSCH is associated with the same coresetPoolIndex as the PDCCH that triggers the non-periodic CSI-RS, and the scheduling offset is greater than or equal to the threshold QCL duration timeDurationForQCL; the other DL signal also refers to other non-periodic CSI-RS, and the PDCCH that triggers the other non-periodic CSI-RS is associated with the same coresetPoolIndex as the PDCCH that triggers the CSI-RS, and the scheduling offset of the other non-periodic CSI-RS is greater than or equal to the threshold beam switching timing beamSwitchTiming reported by the UE, which The UE reports one of the values ​​{14,28,48} and enableBeamSwitchTiming is not configured; the other DL signal also refers to other non-periodic CSI-RS, the PDCCH triggering the other non-periodic CSI-RS is associated with the same coresetPoolIndex as the PDCCH triggering the CSI-RS, and the scheduling offset of the other non-periodic CSI-RS is greater than or equal to 48, wherein the beamSwitchTiming-r16 reported by the UE is one of the values ​​{224,336}, and enableBeamSwitchTiming is configured; the other DL signal also refers to periodic CSI-RS or semi-persistent CSI-RS.

[0067] Otherwise, the UE applies the QCL parameters of the CORESET associated with the monitoring search space to receive CSI-RS, where the CORESET is the CORESET with the smallest controlResourceSetId in the most recent time slot and among the CORESETs configured with the same CoreSetPoolIdex value as the PDCCH that triggers the CSI-RS, and in the most recent time slot, one or more CORESETs are associated with the same coresetPoolIndex value as the PDCCH that triggers the CSI-RS.

[0068] If condition 2 is met or condition 2 is met and condition 1 is not met, the second behavior is performed; wherein condition 2 includes: if the UE is configured with enableTwoDefaultTCI-States and at least one TCI code point is mapped to two TCI States. The second behavior includes:

[0069] If there is any other DL signal using the TCI state indicated by the network side device in the same symbol as the CSI-RS, the UE applies the QCL assumption of the other DL signal to receive the CSI-RS. The other DL signal refers to the PDSCH with a scheduling offset greater than or equal to the threshold timeDurationForQCL; the other DL signal also refers to other non-periodic CSI-RS, the scheduling offset of which is greater than or equal to the threshold beamSwitchTiming reported by the UE, where the UE reports one of the values ​​{14, 28, 48} and enableBeamSwitchTiming is not configured; the other DL signal also refers to other non-periodic CSI-RS, the scheduling offset of which is greater than or equal to 48, where the beamSwitchTiming-r16 reported by the UE is one of the values ​​{224, 336} and enableBeamSwitchTiming is configured; the other DL signal also refers to periodic CSI-RS or semi-persistent CSI-RS. If the PDSCH present in the same symbol as the CSI-RS is indicated by the network with two TCI states, the UE applies the first TCI state of the two TCI states when receiving the aperiodic CSI-RS.

[0070] Otherwise, the UE applies the first TCI state of the two TCI states corresponding to the lowest TCI code point, where the lowest TCI code point is the lowest code point of all TCI code points corresponding to the two TCI states, and is applicable to the PDSCH within the activated bandwidth part (BWP) of the cell where the non-periodic CSI-RS is located.

[0071] When condition 3 is satisfied and condition 1 and condition 2 are not satisfied, the third behavior is performed; wherein condition 3 includes: if there is any other DL signal using the TCI state indicated by the network side device in the same symbol as the CSI-RS. The third behavior includes:

[0072] The UE applies the QCL assumption of another DL signal to receive non-periodic CSI-RS. Another DL signal refers to a PDSCH with a scheduling offset greater than or equal to the threshold timeDurationForQCL; another DL signal also refers to a periodic CSI-RS or a semi-persistent CSI-RS; another DL signal also refers to other non-periodic CSI-RS, the scheduling offset of which is greater than or equal to the threshold beamSwitchTiming reported by the UE, where the UE reports one of the values ​​{14,28,48} and enableBeamSwitchTiming is not configured; another DL signal also refers to other non-periodic CSI-RS, the scheduling offset of which is greater than or equal to the threshold beamSwitchTiming reported by the UE, where the NZP-CSI-RS resource set is configured with the high-level parameter trs-info; another DL signal also refers to other non-periodic The other non-periodic CSI-RS has a scheduling offset greater than or equal to 48, wherein the UE reports beamSwitchTiming-r16 and enablesBeamSwitchTiming is configured, and the NZP-CSI-RS resource set is configured with a high-level parameter repetition set to "off" or is not configured with high-level parameters repetition and trs-info; the other DL signal also refers to other non-periodic CSI-RS, and the scheduling offset of the other non-periodic CSI-RS is greater than or equal to the threshold beamSwitchTiming-r16 reported by the UE, wherein enableBeamSwitchTiming is configured, and the NZP-CSI-RS resource set is configured with a high-level parameter repetition set to "on".

[0073] When condition 4 is met and condition 1, condition 2, and condition 3 are not met, the fourth behavior is performed; wherein condition 4 includes: the network side device configures at least one CORESET for the BWP where the non-periodic CSI-RS is located. The fourth behavior includes: the UE applies the QCL parameters of the CORESET associated with the monitoring search space to receive the CSI-RS, wherein the CORESET is the CORESET with the smallest controlResourceSetId in the most recent time slot, and there are one or more CORESETs monitored by the UE in the activated BWP of the serving cell in the most recent time slot.

[0074] If conditions 1, 2, 3 and 4 are not met, and if the UE is configured with enableDefaultBeamForCCS, the UE applies the QCL assumption of the activated TCI state with the lowest ID to receive the non-periodic CSI-RS, where the activated TCI state is used for the PDSCH within the activated BWP of the cell where the non-periodic CSI-RS is located.

[0075] 3. Power control parameters of Sounding Reference Signal (SRS).

[0076] The power control parameters p0 and alpha of the SRS may be determined according to the p0 and alpha parameters configured by the network side device for each SRS resource set. The network side device may also update or reconfigure the parameters through RRC.

[0077] For the path loss parameter in the power control parameter, when the pathlossReferenceRS of an SRS resource set is configured, the path loss of the set is determined according to the path loss RS configured in the SRS resource set.

[0078] If the pathlossReferenceRS is not configured, the network side can configure the pathlossRefereceRSList in the SRS resourceset, that is, configure multiple path loss RSs, and determine a path loss RS from the multiple path loss RSs through MAC CE to determine the path loss of the SRS resource set. The above is only for non-periodic and semi-continuous SRSresource sets. When the enablePL-RS-UpdateForPUSCH-SRS parameter is configured, the path loss RS can be selected or updated through MAC CE.

[0079] 4. 3GPP Release17 unified TCI framework (TCI framework).

[0080] TCI state includes a joint TCI state and a separate TCI state, wherein the former is that multiple downlink and uplink channels use the same TCI state, and the latter includes a separate downlink (separate Downlink, separate DL) TCI state for multiple downlink channels and a separate uplink (separate Uplink, separate UL) TCI state for multiple uplink channels.

[0081] The DL TCI state may be used for a UE-dedicated PDSCH and some or all of the UE-dedicated control resource sets, or in other words, may be used for UE-dedicated reception on the PDSCH and for UE-dedicated reception on some or all of the CORESETs.

[0082] UL TCI state can be used for physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) and all dedicated physical uplink control channel (Physical Uplink Control Channel, PUCCH) resources that are dynamically granted or based on configuration grant.

[0083] In the intra-cell beam indication mechanism, the demodulation reference signal (DMRS) associated with the non-terminal-specific reception on the control resource set and the associated PDSCH can use the TCI state indicated by the network side device for the terminal-specific PDSCH and part or all of the terminal-specific control resource set.

[0084] In the inter-cell beam indication mechanism, in addition to non-terminal dedicated channels or signals, other channels / signals can use the TCI state indicated by the network-side device for the terminal-specific PDSCH and part or all of the terminal-specific control resource sets.

[0085] Both the aperiodic CSI-RS for CSI and the aperiodic CSI-RS for beam management (BM) can use the TCI state indicated by the network side device for the terminal-specific PDSCH and part or all of the terminal-specific control resource sets.

[0086] The non-periodic SRS resources or resource sets for BM, the SRS resources or resource sets for antenna switching / codebook-based uplink transmission / non-codebook-based uplink transmission, can use the TCIstate indicated by the network side device for the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) and all dedicated physical uplink control channel (Physical Uplink Control Channel, PUCCH) resources for dynamic authorization or configuration-based authorization.

[0087] It should be noted that the terminal-dedicated channel in the embodiment of the present application can also be referred to as a terminal-dedicated signal. For the above condition 1, it can be understood that: the terminal is configured with at least two different control resource set pool index values, and the default beam is enabled for each control resource set pool index (the high-level parameter enableDefaultTCI-StatePerCoresetPoolIndex is configured).

[0088] The above condition 2 can be understood as: the terminal is configured with a mode for starting at least two default beams (the high-level parameter enableTwoDefaultTCI-States is configured), and when the TCI state is activated, at least one TCI code point corresponds to at least two TCI states.

[0089] The transmission processing method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0090] See also Figure 2 , Figure 2 is a flow chart of a transmission processing method provided by an embodiment of the present application, such as Figure 2 As shown, the following steps are included:

[0091] Step 201, the terminal obtains target information;

[0092] Step 202, the terminal determines whether the target object uses a target transmission configuration indication state TCI state according to the target information;

[0093] The target information is agreed upon by a protocol or indicated by a network side device, the target object is at least one of a channel state information reference signal CSI-RS and a sounding reference signal SRS; the target TCI state includes at least one of the following:

[0094] TCIstate for terminal-specific physical downlink shared channel PDSCH and for all or part of the dedicated control resource set, i.e. for UE-specific reception on PDSCH and UE-specific reception on part or all of CORESET;

[0095] TCI state for the Physical Uplink Shared Channel (PUSCH) and all dedicated Physical Uplink Control Channels (PUCCH) that are dynamically scheduled or based on configuration grants.

[0096] In the embodiment of the present application, the above-mentioned target TCI state can be understood as the TCIstate used to indicate the common beam. Based on the target information, the terminal can determine whether the target object uses the target TCI state. If the target TCI state is used, it means that the common beam is used. If the target TCI state is not used, it means that the common beam is not used. At this time, other pre-configured beams, other beams indicated by the network, or the default beam can be used.

[0097] It should be understood that the above CSI-RS may include only aperiodic CSI-RS, and the above SRS may include only aperiodic SRS.

[0098] Optionally, when the target TCI state is a TCI state for terminal-specific PDSCH and for all or part of the dedicated control resource set, the target TCI state can be understood as a separate DL TCI state; when the target TCI state is a TCI state for PUSCH and all dedicated physical uplink control channels PUCCH for dynamic scheduling or based on configuration authorization, the target TCI state can be understood as a separate UL TCI state. When the target TCI state is used for both terminal-specific PDSCH and all or part of the dedicated control resource set, and for PUSCH and all dedicated PUCCH for dynamic scheduling or based on configuration authorization, the above target TCI state can be understood as a joint TCI state.

[0099] It should be noted that when it is determined based on the target information that the CSI-RS and / or SRS use a common beam, the beam information of the CSI-RS and / or SRS indicated by the network side device may be defaulted.

[0100] In an embodiment of the present application, target information is obtained through a terminal; and it is determined whether the target object uses a target transmission configuration indication state TCI state according to the target information; wherein the target information is agreed upon by a protocol or indicated by a network-side device, and the target object is at least one of a channel state information reference signal CSI-RS and a sounding reference signal SRS; the target TCI state includes at least one of the following: a TCI state for a terminal-specific physical downlink shared channel PDSCH and for all or part of a dedicated control resource set; a TCI state for a physical uplink shared channel PUSCH and all dedicated physical uplink control channels PUCCH for dynamic scheduling or based on configuration authorization. In this way, when the network-side device indicates a common beam, the terminal can determine whether the CSI-RS and / or SRS uses the target TCI state according to the target information, thereby determining the beam information of the CSI-RS and / or SRS, so as to ensure that the terminal and the network-side device have a consistent understanding of the beam when transmitting the CSI-RS and / or SRS, and ensure beam alignment.

[0101] Optionally, in some embodiments, the target information satisfies at least one of the following:

[0102] The target information is used to indicate whether all the target objects use the target TCI state;

[0103] The target information is used to indicate whether all target objects in the resource set corresponding to the target object use the target TCI state;

[0104] The target information is used to indicate whether the resource corresponding to the target object uses the target TCI state;

[0105] The target information is used to indicate whether all target objects in the configuration corresponding to the target object use the target TCI state;

[0106] The target information is used to indicate whether the target objects of different purposes use the target TCI state.

[0107] Optionally, when the target information can be indicated by the network side device, the target information is carried in any of the following configuration information;

[0108] Configuration information of a resource set of the target object;

[0109] Configuration information of the target object;

[0110] Configuration information of resources of the target object;

[0111] Configuration information of the cell to which the target object belongs;

[0112] Configuration information of the bandwidth part BWP to which the target object belongs;
