[0022] 1 is a block diagram of a wireless communication system to which the embodiments of the present application can be applied. The wireless communication system includes a terminal 11 and a network side device 12. Among them, the terminal 11 may be a terminal-side device such as a mobile phone, a tablet personal computer, a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a personal digital assistant, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, a vehicle user equipment (VUE), a pedestrian user equipment (PUE), a smart home (household equipment with wireless communication functions, such as a refrigerator, a television, a washing machine, or furniture), etc. Wearable devices include a smart watch, a smart wristband, a smart earphone, a smart glass, smart jewelry (smart bangle, smart bracelet, smart ring, smart necklace, smart anklet bangle, smart anklet, etc.), a smart wrist strap, a smart wear, a game console, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application.The network side device 12 may be a base station or a core network device, of which the base station may be called a Node B, an evolved Node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved Node B (eNB), a home B node, a home evolved B node, a wireless local area network (WLAN) access point, a wireless fidelity (WiFi) node, a transmitting receiving point (TRP), or any other suitable term in the field.

[0023] For ease of understanding, some of the contents relating to the embodiments of the present application will be described below.

[0024] 1. Beam indication mechanism 5th generation mobile communications (5 th In a 5G (Next Generation) NR system, after beam measurement and beam reporting, the network side equipment can establish a beam link between the network side equipment and the UE and perform beam direction on the downlink and uplink channels or reference signals to realize the transmission of the channels or reference signals.

[0025] The mechanism of beam instruction for CSI-RS is as follows. If the CSI-RS type is periodic CSI-RS, the network side device sets beam information for the CSI-RS resource by Radio Resource Control (RRC) signaling, If the CSI-RS type is semi-persistent CSI-RS, the network side device indicates the beam information when activating the CSI-RS resource from the RRC-configured CSI-RS resource set by a Medium Access Control Element (MAC CE) command. If the CSI-RS type is aperiodic CSI-RS, the network side device sets beam information for the CSI-RS resource through RRC signaling and triggers the CSI-RS using downlink control information (DCI).

[0026] Alternatively, the beam information referred to in this application may 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, QCL parameters, etc. Here, downlink beam information can generally be represented by TCI state information or QCL information. Uplink beam information can generally be represented by spatial relation information.

[0027] II. Default beam mechanism for aperiodic CSI-RS In the 5G NR system, a default beam mechanism for aperiodic CSI-RS is defined, specifically as follows:

[0028] If the scheduling offset between the last symbol of the physical downlink control channel (PDCCH) carrying the trigger DCI and the first symbol of an aperiodic CSI-RS resource in a Non-Zero Power (NZP) CSI Reference Signal (RS) (NZP-CSI-RS) resource set (where the higher-level parameter trs-Info (trs-Info refers to a parameter of the Tracking Reference Signal (TRS) message) is not configured) is less than the threshold beam switch timing reported by the UE, and the reported value is one of the values ​​{14, 28, 48} and enableBeamSwitchTiming (enableBeamSwitchTiming refers to a parameter that enables beam switch timing) is not configured, or if the scheduling offset is less than 48 and the UE uses beamSwitchTiming-r16 (beamSwitchTiming-r16 refers to Release 16 If the UE reports a beam switching timing parameter (referring to the beam switching timing parameter in the NZP-CSI-RS resource set) and enableBeamSwitchTiming is configured and the higher level parameter repetition configured in the NZP-CSI-RS resource set is set to 'off' or the higher level parameter repetition is not configured, or if the scheduling offset is smaller than the threshold beamSwitchTiming-r16 reported by the UE, enableBeamSwitchTiming is configured and the higher level parameter repetition configured in the NZP-CSI-RS resource set is set to 'on', then the following actions exist:

[0029] If condition 1 is satisfied, execute a first action, where condition 1 includes an assumption that enableDefaultTCI-StatePercoResetPoolidex (enableDefaultTCI-StatePercoResetPoolidex refers to a parameter that enables a default TCI state for each control resource set (CORESET) pool index) is configured in the UE, and a higher-level parameter PDCCH Config (PDCCH Config refers to a parameter that is configured in the PDCCH) is configured in the UE, and the control resource set (ControlResourceSet) of the parameter includes two different control resource set pool index (coresetPoolIndex) values. The first action includes:

[0030] If there is any other downlink (DL) signal in the same symbol as the CSI-RS and in the TCI state indicated by the network side device, the UE receives the aperiodic CSI-RS by applying the QCL assumption of the other DL signal. The other DL signal refers to a physical downlink shared channel (PDSCH) scheduled by a PDCCH, where the PDCCH that schedules the PDSCH is associated with the same coresetPoolIndex as the PDCCH that triggers the aperiodic CSI-RS, and the scheduling offset is equal to or greater than a threshold QCL duration (timeDurationForQCL). Another DL signal may also refer to another aperiodic CSI-RS, where the PDCCH triggering the other aperiodic CSI-RS is associated with the same coresetPoolIndex as the PDCCH triggering the CSI-RS, and the scheduling offset of the other aperiodic CSI-RS is greater than or equal to a threshold beam switching timing (beamSwitchTiming) reported by the UE, where the UE reports one of the values ​​{14, 28, 48} and enableBeamSwitchTiming is not configured. Another DL signal may also refer to another aperiodic CSI-RS, where the PDCCH triggering the other aperiodic CSI-RS is associated with the same coresetPoolIndex as the PDCCH triggering the CSI-RS, and the scheduling offset of the other aperiodic CSI-RS 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. Another DL signal also refers to a periodic CSI-RS or a semi-persistent CSI-RS.

[0031] In the opposite case, the UE receives the CSI-RS applying the QCL parameters associated with a CORESET monitoring the search space, where the CORESET is the CORESET with the smallest control resource set identifier (controlResourceSetId) among the CORESETs in the nearest slot that have the same coresetPoolIndex value as the PDCCH that triggers the CSI-RS, and where one or more CORESETs in the nearest slot are associated with the same coresetPoolIndex value as the PDCCH that triggers the CSI-RS.

[0032] If condition 2 is met, or if condition 2 is met and condition 1 is not met, perform a second action, where condition 2 includes the assumption that enableTwoDefaultTCI-States (enableTwoDefaultTCI-States refers to a parameter that enables two default TCI states) is configured in the UE and at least one TCI codepoint is mapped to two TCI states. The second action includes:

[0033] If there is any other DL signal that uses the TCI state indicated by the network side device in the same symbol as the CSI-RS, the UE receives the CSI-RS by applying the QCL assumption of the other DL signal. The other DL signal refers to a PDSCH whose scheduling offset is equal to or greater than the threshold timeDurationForQCL. The other DL signal also refers to another aperiodic CSI-RS whose scheduling offset is equal to or greater than the threshold beamSwitchTiming reported by the UE, where the UE reports a value of {14, 28, 48} and enableBeamSwitchTiming is not configured. The other DL signal also refers to another aperiodic CSI-RS whose scheduling offset is equal to or greater than 48, where the beamSwitchTiming-r16 reported by the UE is a value of {224, 336} and enableBeamSwitchTiming is configured. The other DL signal also refers to a periodic CSI-RS or a semi-persistent CSI-RS. If two TCI states are indicated by the network for the PDSCH present in the same symbol as the CSI-RS, the UE shall apply the first of the two TCI states when receiving the aperiodic CSI-RS.

[0034] In the opposite case, 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 among all TCI code points corresponding to the two TCI states and is suitable for the PDSCH within the active bandwidth part (BWP) of the cell where the aperiodic CSI-RS is located.

[0035] If condition 3 is met and condition 1 and condition 2 are not met, perform a third action, where condition 3 includes the assumption that there is any other DL signal that uses the TCI state indicated by the network side device in the same symbol as the CSI-RS. The third action includes:

[0036] The UE receives an aperiodic CSI-RS by applying the QCL assumption of another DL signal. The other DL signal refers to a PDSCH whose scheduling offset is equal to or greater than the threshold timeDurationForQCL. The other DL signal also refers to a periodic CSI-RS or a semi-persistent CSI-RS. The other DL signal also refers to another aperiodic CSI-RS whose scheduling offset is equal to or greater than the threshold beamSwitchTiming reported by the UE, where the UE reports one of the values ​​{14, 28, 48} and enableBeamSwitchTiming is configured. The other DL signal also refers to another aperiodic CSI-RS whose scheduling offset is equal to or greater than the threshold beamSwitchTiming reported by the UE, where the NZP-CSI-RS resource set is configured with the upper parameter trs-info. The other DL signal also refers to another aperiodic CSI-RS, the scheduling offset of which is greater than or equal to 48, where the UE reports beamSwitchTiming-r16, enableBeamSwitchTiming is configured, and the upper level parameter repetition configured in the NZP-CSI-RS resource set is set to "off" or the upper level parameters repetition and trs-info are not configured. The other DL signal also refers to another aperiodic CSI-RS, the scheduling offset of which is greater than or equal to the threshold beamSwitchTiming-r16 reported by the UE, where enableBeamSwitchTiming is configured, and the upper level parameter repetition configured in the NZP-CSI-RS resource set is set to "on".

[0037] If condition 4 is met and none of condition 1, condition 2, and condition 3 are met, execute a fourth action, where condition 4 includes that the network side device has configured at least one CORESET for the BWP in which the aperiodic CSI-RS is located. The fourth action includes: the UE receives the CSI-RS applying a QCL parameter associated with a CORESET monitoring a search space, where the CORESET is the CORESET with the smallest controlResourceSetId in the nearest slot, and there are one or more CORESETs monitored by the UE during the active BWP of the serving cell in the nearest slot.

[0038] If none of Condition 1, Condition 2, Condition 3, and Condition 4 are met, and enableDefaultBeamForCCS (enableDefaultBeamForCCS refers to a parameter that enables the Common Channel Signaling (CCS) default beam) is configured in the UE, the UE receives the aperiodic CSI-RS applying the QCL assumption of the active TCI state with the smallest identification number (Identity Document, ID), where the active TCI state is used for the PDSCH in the active BWP of the cell where the aperiodic CSI-RS is located.

[0039] 3. Power control parameters of the sounding reference signal (SRS) The power control parameters p0 and alpha of the SRS may be determined according to the p0 and alpha parameters set for each SRS resource set by the network side device, and the network side device may also update or reset the parameters via RRC.

[0040] For a path loss parameter among the power control parameters, when a path loss reference signal (pathlossReferenceRS) of a certain SRS resource set is set, the path loss of that set is determined according to the path loss RS set in that SRS resource set.

[0041] If the pathlossReferenceRS is not configured, the network side device configures a pathloss (PL) reference signal list (pathlossReferenceRSList), i.e., multiple pathloss RSs, in the SRS resource set, and the MAC CE determines one pathloss RS from the multiple pathloss RSs to use for determining the pathloss of the SRS resource set. The above applies only to aperiodic and semi-persistent SRS resource sets. If the enablePL-RS-UpdateForPUSCH-SRS parameter (enablePL-RS-UpdateForPUSCH-SRS parameter refers to a parameter that enables updating of the PL RS for PUSCH-SRS) is configured, the MAC CE can select or update the pathloss RS.

[0042] 4. 3rd Generation Partnership Project (3GPP (registered trademark, same as below)) Release 17 (Release 17, R17) unified TCI framework (3GPP R17 unified TCI framework) TCI states include joint TCI states and separate TCI states, of which the former uses the same TCI state for multiple downlink and uplink channels, and the latter includes separate downlink (separate DL) TCI states used for multiple downlink channels and separate uplink (separate UL) TCI states used for multiple uplink channels.

[0043] The DL TCI state can be used for UE-dedicated PDSCH and some or all UE-dedicated control resource sets, or for UE-dedicated reception on PDSCH and UE-dedicated reception on some or all CORESETs.

[0044] The UL TCI state can be used for dynamic or configuration grant based Physical Uplink Shared Channel (PUSCH) and all dedicated Physical Uplink Control Channel (PUCCH) resources.

[0045] In the intra-cell beam direction mechanism, the Demodulation Reference Signal (DMRS) associated with the non-terminal dedicated reception on the control resource set and the associated PDSCH can use the TCI state indicated by the network side equipment for the terminal dedicated PDSCH and for some or all of the terminal dedicated control resource sets.

[0046] In the inter-cell beam direction mechanism, except for channels or signals dedicated to non-terminals, other channels / signals can use the TCI state indicated by the network side equipment for the PDSCH dedicated to the terminal and some or all of the control resource sets dedicated to the terminal.

[0047] Both the aperiodic CSI-RS used for CSI and the aperiodic CSI-RS used for beam management (BM) can use the TCI state indicated by the network side device for the PDSCH dedicated to the terminal and some or all of the control resource sets dedicated to the terminal.

[0048] The aperiodic SRS resource or resource set used for BM, and the SRS resource or resource set used for codebook-based uplink transmission / non-codebook-based uplink transmission in antenna switching can use the TCI state indicated by the network side device for dynamic grant or configuration grant-based PUSCH and all dedicated PUCCH resources.

[0049] It should be noted that the channel dedicated to the terminal in the embodiments of the present application may also be referred to as a signal dedicated to the terminal, and the above condition 1 may also be interpreted as meaning that at least two different control resource set pool index values ​​are configured in the terminal, and the default beam for each control resource set pool index is enabled (the upper parameter enableDefaultTCI-StatePerCoresetPoolIndex is set).

[0050] Regarding the above condition 2, it may be interpreted that a mode that enables at least two default beams is set in the terminal (the upper parameter enableTwoDefaultTCI-States is set), and when a TCI state is activated, at least one TCI code point corresponds to at least two TCI states.

[0051] The transmission processing method provided in the embodiments of the present application will be described in detail below with reference to the drawings according to several embodiments and application scenarios.

[0052] Please refer to FIG. 2, which is a flowchart of a transmission processing method provided in an embodiment of the present application. As shown in FIG. 2, the method includes: Step 201 in which the terminal acquires target information; Step 202: determining whether to use a target transmission configuration indicator state (TCI state) at a target object based on the target information; Wherein, the target information is defined 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), and the target TCI state is: TCI states used for the UE-dedicated physical downlink shared channel PDSCH and all or some of the dedicated control resource sets, i.e., TCI states used for UE-dedicated reception on the PDSCH and UE-dedicated reception on some or all of the CORESETs; and TCI states used for dynamically scheduled or configuration grant-based physical uplink shared channels PUSCH and all dedicated physical uplink control channels PUCCH.

[0053] In the embodiment of the present application, the target TCI state may be interpreted as a TCI state for instructing a common beam. The terminal can determine whether to use the target TCI state for the target object based on the target information. If the target TCI state is used, the terminal will use the common beam. If the target TCI state is not used, the terminal will not use the common beam. In this case, another beam set in advance, another beam instructed by the network, or a default beam can be used.

[0054] It should be understood that the CSI-RS may include only aperiodic CSI-RS, and the SRS may include only aperiodic SRS.

[0055] Alternatively, if the target TCI state is a TCI state used for a UE-dedicated PDSCH and all or some of the dedicated control resource sets, the target TCI state may be interpreted as a separate DL TCI state. If the target TCI state is a TCI state used for a dynamically scheduled or configuration grant-based PUSCH and all of the dedicated physical uplink control channels (PUCCHs), the target TCI state may be interpreted as a separate UL TCI state. If the target TCI state is used for a UE-dedicated PDSCH and all or some of the dedicated control resource sets, and also for a dynamically scheduled or configuration grant-based PUSCH and all of the dedicated PUCCHs, the target TCI state may be interpreted as a joint TCI state.

[0056] It should be noted that when determining the common beam to be used for CSI-RS and / or SRS based on target information, the beam information of CSI-RS and / or SRS instructed by the network side device may be set to a default.

[0057] In an embodiment of the present application, a terminal acquires target information and determines, based on the target information, whether to use a target transmission configuration indicator state (TCI state) for a target object, where the target information is specified 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), and the target TCI state includes at least one of a TCI state used for a terminal-dedicated physical downlink shared channel (PDSCH) and all or some of its dedicated control resource sets, and a TCI state used for a dynamically scheduled or configuration grant-based physical uplink shared channel (PUSCH) and all dedicated physical uplink control channels (PUCCH). In this way, when a common beam is indicated by the network side device, the terminal can determine, based on the target information, whether to use a target TCI state for CSI-RS and / or SRS, thereby determining beam information for CSI-RS and / or SRS, and ensuring that the terminal and the network side device have consistent understanding of the beam when transmitting CSI-RS and / or SRS, and ensuring beam alignment.

[0058] Optionally, in some embodiments, the target information comprises: The target information is for indicating whether or not all the target objects use the target TCI state; The target information is for indicating whether the target TCI state is used in all target objects in a resource set corresponding to the target object; The target information is for indicating whether to use the target TCI state in a resource corresponding to the target object; The target information is for indicating whether or not the target TCI state is to be used in all target objects in a setting corresponding to the target object; The target information is for indicating whether or not the target TCI state is to be used in the target objects of different uses.

[0059] Optionally, when the target information can be indicated by a network side device, the target information can be: Configuration information of the target resource set; setting information of the target object; Configuration information of the target resource; Setting information of a cell to which the target object belongs; Setting information of the bandwidth portion BWP to which the target belongs; Setting information of a cell group to which the target object belongs; and setting information of the frequency band to which the target object belongs.

[0060] For example, when the target information is included in a CSI-RS resource configuration, a CSI-RS resource set, or configuration information of a CSI-RS resource, it can be used to indicate whether to use a target TCI state in the CSI-RS. When the target information is included in configuration information of an SRS resource set or an SRS resource, it can be used to indicate whether to use a target TCI state in the SRS. When the target information corresponds to SRS resource sets for different usages, it can be used to indicate whether to use a target TCI state in the SRS resource set for each usage.

[0061] Optionally, in some embodiments, when the target object includes a first CSI-RS that is aperiodic and a target condition is satisfied, the TCI state of the first CSI-RS is a first TCI state, a second TCI state, a third TCI state, or a fourth TCI state; Here, the target condition includes that a time domain offset between a first PDCCH that triggers the first CSI-RS and the first CSI-RS is less than a first predetermined value.

[0069] Alternatively, the first downlink signal is a first PDSCH or a second aperiodic CSI-RS.

[0070] In the embodiment of the present application, the second CSI-RS may be a periodic CSI-RS, an aperiodic CSI-RS or a semi-persistent CSI-RS.

It should be understood that when the SRS does not use a common beam or a target TCI state, the target power control parameter may be determined according to conventional related techniques.

[0100] Furthermore, in a Carrier Aggregation (CA) scenario, the validity time of the TCI state also needs to be considered, which may be interpreted as a Beam Application Time (BAT). For example, in some embodiments, the method may include: When the terminal is in a carrier aggregation scenario, the method further includes a step of the terminal receiving configuration information from a network side device, the configuration information being for setting target parameter information, and the target parameter information being for indicating a validity time of the target TCI state.

[0111] Alternatively, the target information may indicate whether to use a common beam in SRS resource sets for different usages.

[0112] Alternatively, if the target information indicates that a common beam is to be used for CSI-RS and / or SRS, the beam information indicated by the network side device for each CSI-RS resource and / or SRS resource may be set to a default.
