[0117] Please see Figure 1 , Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can also be referred to as a terminal device or user equipment (UE).

The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only a base station in an NR system is used as an example, but this application embodiment does not limit the specific type of base station and the specific communication system.

[0118] In massive MIMO technology, using an all-digital array can achieve maximum spatial resolution and optimal MU-MIMO performance. However, this structure requires a large number of analog-to-digital / digital-to-analog (AD / DA) conversion devices and a large number of complete RF-baseband processing channels, which will be a huge burden in terms of both equipment cost and baseband processing complexity.

[0119] To avoid the aforementioned implementation costs and equipment complexity, hybrid analog-digital beamforming technology has emerged. This involves adding a beamforming stage to the radio frequency signal near the front end of the antenna system, building upon traditional digital beamforming. Analog beamforming can achieve a relatively coarse match between the transmitted signal and the channel in a simpler way. The equivalent channel dimension formed after analog beamforming is smaller than the actual number of antennas, thus significantly reducing the required AD / DA converters, digital channels, and baseband processing complexity. Residual interference from the analog beamforming section can be processed again in the digital domain, ensuring the quality of MU-MIMO transmission. Compared to all-digital beamforming, hybrid analog-digital beamforming represents a trade-off between performance and complexity, showing high practical potential in high-frequency, high-bandwidth systems or systems with a large number of antennas.

[0120] Research on next-generation communication systems beyond 4G aims to increase the supported operating frequency bands to above 6GHz, with a maximum of approximately 100GHz. High-frequency bands have relatively abundant idle frequency resources, providing greater throughput for data transmission. The shorter wavelengths of high-frequency signals allow for the placement of more antenna elements on the same antenna panel compared to low-frequency bands, enabling the formation of more directional and narrower beams using beamforming technology. Therefore, combining massive MIMO with high-frequency communication is also a future trend.

[0121] Analog beamforming is transmitted across the full bandwidth, and each polarization element on the antenna panel of each high-frequency antenna array can only transmit an analog beam in a time-division multiplexed manner. The beamforming weights of the analog beam are achieved by adjusting the parameters of devices such as the RF front-end phase shifter.

[0122] Currently, a polling method is typically used to train simulated beamforming vectors. Each element on each antenna panel, in each polarization direction, sequentially transmits training signals (i.e., candidate beamforming vectors) at predetermined times using time-division multiplexing. The terminal then measures and sends back a beam report, which the network uses to implement simulated beam transmission in the next transmission. The beam report typically includes the identifiers of several optimal transmit beams and their corresponding received power or signal-to-interference-plus-noise ratio (SNR).

[0123] During beam measurement, the network configures a reference signal resource set (RSresource set), which includes at least one reference signal resource, such as an SSB resource or a CSI-RS resource. The UE measures the L1-RSRP / L1-SINR of each RS resource and reports at least one optimal measurement result to the network. The reported content includes the SSBRI or CRI and the corresponding L1-RSRP / L1-SINR. This report reflects at least one optimal beam and its quality, allowing the network to determine the beam information used to transmit channels or signals with the UE.

[0124] After beam measurement and beam reporting, the network can perform beam indication on the downlink and uplink channels or reference signals to establish beam links between the network and the UE, and realize the transmission of channels or reference signals.

[0125] For PDCCH beam indication, the network uses Radio Resource Control (RRC) signaling to configure K Transmission Configuration Indication (TCI) states for each CORESET. When K > 1, one TCI state is indicated or activated by the Media Intervention Control Element (MAC CE). When K = 1, no additional MAC CE command is required. When the UE is listening to the PDCCH, it uses the same quasi-colocation (QCL) information for the entire search space within the CORESET, i.e., it uses the same TCI state to listen to the PDCCH. The source reference signal (e.g., periodic CSI-RS resource, semi-persistent CSI-RS resource, SS block, etc.) in this TCI state has a spatial QCL with the UE-specific PDCCH demodulation reference signal (DMRS) port. The UE can determine which receive beam to use to receive the PDCCH based on this TCI state.

[0126] For PDSCH beam indication, the network configures M TCI states via RRC signaling, and then activates them using the MAC CE command. NThe UE generates a TCI state and then notifies the UE of the TCI state via the N-bit TCI field of the Downlink Control Information (DCI). The reference signal in this TCI state is QCL with the DMRS port of the PDSCH to be scheduled. Based on this TCI state, the UE can determine which receive beam to use to receive the PDSCH.

[0127] For CSI-RS beam indication, when the CSI-RS type is periodic CSI-RS, the network configures QCL information for the CSI-RS resource via RRC signaling. When the CSI-RS type is semi-persistent CSI-RS, the network indicates its QCL information when activating a CSI-RS resource from the RRC-configured CSI-RS resource set via MAC CE command. When the CSI-RS type is aperiodic CSI-RS, the network configures the QCL for the CSI-RS resource via RRC signaling and uses DCI to trigger the CSI-RS.

[0128] For beam indication of the Physical Uplink Control Channel (PUCCH), the network uses RRC signaling to configure spatial relation information for each PUCCH resource via the parameter PUCCH-SpatialRelationInfo. When multiple spatial relation information items are configured for a PUCCH resource, one of them is activated using MAC-CE. When only one spatial relation information item is configured for a PUCCH resource, no additional MAC-CE command is required.

[0129] For beam indication of the Physical Uplink Shared Channel (PUSCH), the spatial relation information of PUSCH is determined by each SRI codepoint in the SRS resource indicator (SRI) field of the DCI carried by the PDCCH when scheduling PUSCH. This SRI is used to indicate the spatial relation information of PUSCH.

[0130] For beam indication of the Sounding Reference Signal (SRS), when the SRS type is periodic SRS, the network configures spatial relation information for the SRS resource via RRC signaling. When the SRS type is semi-persistent SRS, the network activates one from a set of spatial relation information configured by RRC via the MAC CE command. When the SRS type is aperiodic SRS, the network configures spatial relation information for the SRS resource via RRC signaling, and can also update the spatial relation information of the aperiodic SRS resource using the MAC CE command.

[0131] The beam information mentioned above can also be referred to as: beam information, spatial relation information, spatial domain transmission filter information, spatial filter information, transmission configuration indication state (TCI state) information, quasi-co-location (QCL) information, or QCL parameters, etc. Downlink beam information is typically represented using TCI state information or QCL information. Uplink beam information is typically represented using spatial relation information.

[0132] The antenna panel mentioned can also be referred to as: antenna group, antenna port group, antenna assembly, antenna port assembly, beam assembly, beam sub-assembly, antenna array, antenna port array, antenna sub-array, antenna port sub-array, logical entity, entity, or antenna entity, etc.

[0133] Panel identifiers can include: antenna panel identifier, reference signal resource identifier, reference signal resource set identifier, TCI status identifier, QCL information identifier, spatial relationship identifier, etc.

[0134] This application provides a method for obtaining communication resources, such as... Figure 2 As shown, the method includes:

[0135] Step 101: The terminal receives first indication information from the network-side device. The first indication information is used to indicate the transmission of a channel or reference signal. The first indication information includes beam information and / or antenna panel information.

[0136] In this embodiment, the network-side device sends a first indication information to the terminal. The first indication information is used to indicate the transmission of a channel or reference signal. The first indication information includes beam information and / or antenna panel information. In this way, when the terminal supports multiple antenna panels, the network-side device can indicate the switching of antenna panels and / or the switching of beams, support data transmission for terminals with multiple antenna panels, and instruct the terminal to select antenna panels and / or switch antenna panels, so that the terminal can select the beam on the optimal antenna panel for transmission and ensure communication performance.

[0137] In some embodiments, the first indication information includes any one of the following:

[0138] The network-side device determines the beam information and / or antenna panel information based on the uplink performance and downlink performance;

[0139] The network-side device determines the beam information and / or antenna panel information based on the uplink performance or downlink performance. In this case, the uplink beam and downlink beam can be different. The uplink beam or downlink beam can be the beam on the currently active antenna panel or the beam on the inactive antenna panel.

[0140] In some embodiments, the beam information and / or antenna panel information determined based on uplink and downlink performance includes at least one of the following:

[0141] The beam information is determined based on whether the difference between the first parameter value of the downlink between the current beam and the beam to be switched meets the first preset condition, and whether the difference between the second parameter value of the uplink between the current beam and the beam to be switched meets the second preset condition.

[0142] Antenna panel information is determined based on whether the difference between the third parameter value of the downlink on the currently activated antenna panel and the inactive antenna panel meets the third preset condition, and whether the difference between the fourth parameter value of the uplink on the currently activated antenna panel and the inactive antenna panel meets the fourth preset condition.

[0143] The antenna panel information is determined based on whether the difference between the fifth parameter value of the downlink on the antenna panel where the current beam is located and other antenna panels meets the fifth preset condition, and whether the difference between the sixth parameter value of the uplink on the antenna panel where the current beam is located and other antenna panels meets the sixth preset condition.

[0144] Wherein, the first parameter value is the downlink quality value;

[0145] The second parameter value includes at least one of the following: uplink quality value, transmit power, beam power management - maximum power reduction value.

[0146] The uplink quality value and downlink quality value can be obtained by using any of the following quality parameters or the average value obtained by multiple consecutive measurements of any of the following quality parameters: Reference Signal Received Power (RSRP); Reference Signal Received Quality (RSRQ); Signal-to-Interference-plus-Noise Ratio (SINR); and Received Signal Strength Indication (RSSI).

[0147] The beam information and / or antenna panel information determined by the network-side equipment based on uplink and downlink performance can be determined by, when the terminal supports only one beam transmission, whether the difference in the first downlink parameter value between the current beam and the beam to be switched meets a first preset condition, and whether the difference in the second uplink parameter value between the current beam and the beam to be switched meets a second preset condition. When the terminal only supports one beam transmission, the downlink and uplink beams have beam consistency; that is, the beam information of the terminal's uplink transmit beam and downlink receive beam are the same except for direction. The same applies to the downlink transmit beam and uplink receive beam of the network-side equipment. In other words, the downlink beam and uplink beam correspond to the same beam link. Therefore, if a terminal needs to switch from its current uplink beam to the uplink beam to be switched due to poor uplink quality, then the downlink also needs to be switched from its current downlink beam to the downlink beam to be switched. After the beam switch, the uplink quality may improve, but the downlink quality of the beam may become worse. Therefore, when switching, one cannot only consider uplink quality or downlink quality, but must take both uplink quality and downlink quality into account.

[0148] The antenna panel information determined by the network-side device based on uplink performance and downlink performance can be determined when the terminal supports an active antenna panel, based on whether the difference between the third parameter value of the downlink on the currently active antenna panel and the inactive antenna panel meets a third preset condition, and whether the difference between the fourth parameter value of the uplink on the currently active antenna panel and the inactive antenna panel meets a fourth preset condition. If a terminal can only support one active antenna panel, and the terminal needs to switch from the currently active antenna panel to an inactive one because the uplink quality of the uplink beam on the currently active panel is poor, the terminal will activate the inactive antenna panel to which it needs to switch and deactivate the original active antenna panel. It will then use the uplink beam on the newly activated antenna panel to obtain better uplink quality. In this case, the downlink beam also needs to be switched to the newly activated antenna panel. After the antenna panel switch, the uplink quality may improve, but the downlink quality may become worse. Therefore, when switching antenna panels, it is not possible to consider only the uplink quality or the downlink quality, but to take both uplink quality and downlink quality into account.

[0149] The aforementioned preset conditions can be network-side device configurations or protocol agreements.

[0150] In some embodiments, if the first indication information includes beam information and / or antenna panel information determined by the network-side device based on uplink performance or downlink performance, the beam is either the beam on the currently active antenna panel or the beam on the currently inactive antenna panel.

[0151] In some embodiments, if the channel or reference signal is a non-periodic channel or reference signal, the time offset between the first indication information and the channel or reference signal is greater than or equal to the duration required for beam switching or antenna panel switching. This allows the terminal time to perform beam switching or antenna panel switching, ensuring communication continuity.

[0152] In this embodiment, the first indication information may specifically be downlink control information (DCI).

[0153] In some embodiments, the channel includes at least one of the following: uplink physical shared channel (PUSCH) and downlink physical shared channel (PDSCH);

[0154] The reference signal includes at least one of the following: CSI-RS, SRS.

[0155] In some embodiments, the time offset value is at least one offset value agreed upon by the protocol or configured by the network-side device for beam switching or antenna panel switching. Multiple offset values ​​may be agreed upon by the protocol or configured by the network-side device, and at least one of these offset values ​​may be used as the time offset value.

[0156] In some embodiments, if antenna panel switching is required, the method further includes obtaining second indication information, the second indication information including at least one of the following:

[0157] The network-side device is configured with candidate TCI states or TCI state pools or candidate spatial relationships or spatial relationship pools.

[0158] The network-side device activates a set of TCI states, QCL information, or spatial relationships.

[0159] The TCI status or QCL information or spatial relationship of the channel or reference signal activated or indicated by the network-side device;

[0160] The identification information of the target antenna panel to be switched, indicated by the network-side device.

[0161] The second indication information can be Radio Resource Control (RRC) signaling, Media Access Control (MAC) Control Element (CE) command, or Downlink Control Information (DCI) signaling.

[0162] In some embodiments, the antenna panel information may be determined based on the second indication information in the following ways:

[0163] In method one, the network-side device can configure an information pool corresponding to the antenna panel for the terminal via higher-layer signaling such as RRC signaling. This pool can be called a TCI state pool, a candidate TCI state pool, a spatial relationship pool, or a candidate spatial relationship pool. Each information pool includes multiple TCI states, QCL information, or spatial relationships. If the terminal supports multiple antenna panels, a corresponding information pool is configured for each antenna panel. The network-side device can then activate a set of TCI states, QCL information, or spatial relationships from one information pool via MAC CE, or indicate TCI states, QCL information, or spatial relationships from one information pool via RRC signaling, MAC CE commands, or DCI signaling (such as the first indication information). Alternatively, it can indicate TCI states, QCL information, or spatial relationships from a set of TCI states, QCL information, or spatial relationships activated by the MAC CE. Based on the correspondence between the information pool and the antenna panel, it can be determined which antenna panel of the terminal the channel or reference signal indicated by the first indication information corresponds to, and which antenna panel the network-side device will transmit with.

[0164] Method Two: The information pool configured by the network-side device for the terminal does not correspond to the terminal's antenna panel. When the network-side device activates a set of TCI states, QCL information, or spatial relationships from the information pool using a MAC CE command, the activated set of TCI states, QCL information, or spatial relationships corresponds to the terminal's antenna panel. Then, the network-side device indicates the TCI states, QCL information, or spatial relationships from the set activated by the MAC CE via RRC signaling, a MAC CE command, or DCI signaling (such as the first indication information). Based on the correspondence between the activated set of TCI states, QCL information, or spatial relationships and the antenna panel, it can be determined which antenna panel of the terminal the channel or reference signal indicated by the first indication information corresponds to, and which antenna panel the network-side device will transmit with.

[0165] Method 3: If the information pool configured by the network-side device for the terminal and / or a set of TCI states or QCL information or spatial relationships activated by the network-side device using MAC CE commands do not correspond to the terminal's antenna panel, the network-side device can use RRC signaling or MAC CE commands to activate or DCI signaling to indicate the TCI states or QCL information or spatial relationships. The activated or indicated TCI states or QCL information or spatial relationships correspond to the antenna panel, or the source reference signal in the activated or indicated TCI states or QCL information or spatial relationships corresponds to the antenna panel. Based on this, it can be determined which antenna panel of the terminal the channel or reference signal indicated by the first indication information corresponds to, and which antenna panel the network-side device will transmit with.

[0166] Method 4: The network-side equipment uses RRC signaling, MAC CE command, or DCI signaling to send the identification information of the target antenna panel, and the terminal determines the target antenna panel to be used or switched to based on this information.

[0167] Among them, methods one to three are implicit target antenna panels, and method four is an explicit target antenna panel.

[0168] In some embodiments, the second indication information differs from the first indication information, and the second indication information is sent to the terminal by the network-side device before the first indication information. The terminal determines the antenna panel information based on the second indication information and uses the determined antenna panel to transmit the channel or reference signal indicated by the first indication information to the network-side device.

[0169] In some embodiments, the second instruction information is different from the first instruction information, and the second instruction information is sent to the terminal by the network-side device after the first instruction information.

[0170] The second indication information may include the antenna panel information used for the channel or reference signal transmission indicated by the first indication information, or rewrite the antenna panel information in the first indication information. In the rewriting method, the network-side device uses the second indication information to reconfigure the correspondence between the information pool and the antenna panel, or reactivates another set of TCI states, QCL information, or spatial relationships corresponding to other antenna panels different from those in the first indication information, or reactivates or indicates TCI states, QCL information, or spatial relationships corresponding to other antenna panels different from those in the first indication information, or re-indicates the identification information of other antenna panels different from those in the first indication information. Then, the terminal uses the antenna panel determined by the second indication information to transmit the channel or reference signal with the network-side device.

[0171] In some embodiments, the second indication information is the same as the first indication information, that is, the first indication information carries antenna panel information, such as explicitly carrying an antenna panel identifier, or implicitly determining the antenna panel information through the TCI state, QCL information, or spatial relationship corresponding to the antenna panel. In some embodiments, if the channel or reference signal indicated by the first indication information corresponds to an antenna panel, then when switching antenna panels, the target antenna panel to be switched can be determined based on the first indication information, and it is not necessary to indicate the target antenna panel to be switched through the second indication information.

[0172] In some embodiments, the second indication information can be carried by the DCI and transmitted between the PDCCH and PDSCH.

[0173] In some embodiments, if the second indication information includes candidate TCI states or TCI state pools or candidate spatial relationships or spatial relationship pools configured by the network-side device,

[0174] The candidate TCI state or TCI state pool or candidate spatial relationship or spatial relationship pool corresponds to an inactive antenna panel, an antenna panel that is currently unused but activated, or an antenna panel other than the antenna panel where the current beam is located.

[0175] In some embodiments, if the second indication information includes a set of TCI states, QCL information, or spatial relationships activated by the network-side device,

[0176] The set of TCI states, QCL information, or spatial relationships corresponds to an inactive antenna panel, an currently unused but activated antenna panel, or an antenna panel other than the one currently containing the beam; or,

[0177] The candidate TCI state or TCI state pool to which the set of TCI states belongs, or the candidate spatial relationship or spatial relationship pool to which the set of spatial relationships belongs, corresponds to an inactive antenna panel, an antenna panel that is currently unused but activated, or an antenna panel other than the antenna panel where the current beam is located.

[0178] In some embodiments, if the second indication information includes the TCI state or QCL information or spatial relationship of the channel or reference signal activated or indicated by the network-side device,

[0179] The TCI status, QCL information, or spatial relationship corresponds to an inactive antenna panel, an currently unused but activated antenna panel, or an antenna panel other than the one currently containing the beam; or,

[0180] The source reference signal in the TCI status, QCL information, or spatial relationship corresponds to an inactive antenna panel, an currently unused but activated antenna panel, or an antenna panel other than the antenna panel where the current beam is located; or,

[0181] The candidate TCI state or TCI state pool to which the TCI state belongs, or the candidate spatial relationship or spatial relationship pool to which the spatial relationship belongs, corresponds to an inactive antenna panel, an currently unused but activated antenna panel, or an antenna panel other than the antenna panel where the current beam is located; or

[0182] The TCI state belongs to a set of TCI states activated by the network-side device, or the spatial relationship belongs to a set of spatial relationships activated by the network-side device, corresponding to an inactive antenna panel, an antenna panel that is currently unused but activated, or an antenna panel other than the antenna panel where the current beam is located.

[0183] In some embodiments, if the terminal only supports one active antenna panel, the channel or reference signal corresponds to the same antenna panel; or, the source reference signal of the TCI state or QCL information or spatial relationship of the channel or reference signal corresponds to the same antenna panel.

[0184] In some embodiments, if the first indication information schedules uplink channel or reference signal transmission, the downlink channel or reference signal uses a default beam; or

[0185] If the first indication information schedules the transmission of the downlink channel or reference signal, the uplink channel or reference signal uses the default beam.

[0186] In this scenario, if the terminal only supports one antenna panel, and the first indication information indicates an uplink switch, such as switching to the uplink beam on another antenna panel, then the downlink beam also needs to be switched to that other antenna panel. Before the other antenna panel receives signaling from the network-side device to update the downlink beam information, the downlink channel or reference signal can use the default beam to ensure communication continuity.

[0187] In some embodiments,

[0188] If the first indication information schedules the transmission of the uplink channel or reference signal, and the third source reference signal in the TCI state or QCL information of the downlink channel or reference signal is the same as or associated with the second source reference signal, then the second source reference signal is the source reference signal in the spatial relationship of the uplink channel or reference signal; or

[0189] If the first indication information schedules the transmission of the uplink channel or reference signal, the downlink channel or reference signal uses the source reference signal in the TCI state or QCL information of the specific control resource set CORESET corresponding to the antenna panel where the uplink channel or reference signal is located; or

[0190] If the first indication information schedules the transmission of the uplink channel or reference signal, the downlink channel or reference signal uses the source reference signal in the TCI state or QCL information of the specific control resource set CORESET with the same TRP identification information as the uplink channel or reference signal; or

[0191] If the first indication information schedules the transmission of the downlink channel or reference signal, and the fifth source reference signal in the spatial relationship of the uplink channel or reference signal is the same as or associated with the fourth source reference signal, then the fourth source reference signal is the source reference signal in the TCI state or QCL information of the downlink channel or reference signal; or

[0192] If the first indication information schedules downlink channel or reference signal transmission, the uplink channel or reference signal uses the source reference signal in the TCI state or QCL information of the specific control resource set CORESET corresponding to the antenna panel where the downlink channel or reference signal is located; or

[0193] If the first indication information schedules the transmission of the downlink channel or reference signal, the uplink channel or reference signal uses the source reference signal in the TCI state or QCL information of the specific control resource set CORESET with the same TRP identification information as the downlink channel or reference signal.

[0194] In this embodiment, the channel or reference signal and the specific CORESET correspond to the same TRP identification information, which includes an index that implicitly represents the TRP identification, such as the higher-layer parameter CORESETPoolIndex.

[0195] In some embodiments, the channel or reference signal is transmitted after a duration T, or the first indication information is received after a duration T.

[0196] In some embodiments,

[0197] The duration T shall be at least one of the following:

[0198] The duration K3 after the terminal receives the second indication information;

[0199] The duration between the terminal receiving the second indication information and the terminal sending the confirmation information of the second indication information;

[0200] The duration between the terminal receiving the second indication information and the terminal sending the confirmation information of the second indication information is plus the duration K4.

[0201] The time required to switch the terminal's antenna panel;

[0202] The maximum value between the duration K3 after the terminal receives the second indication information and the duration required for the terminal's antenna panel to switch;

[0203] The maximum value of the time between the terminal receiving the second indication information and the confirmation information sent by the terminal to the second indication information, and the time required for the terminal to switch antenna panels;

[0204] The maximum value of the following: the time between the terminal receiving the second indication information and the confirmation information sent by the terminal to the second indication information, plus the time K4, and the time required for the terminal's antenna panel to switch.

[0205] In some embodiments, the durations K3 and K4 are values ​​agreed upon by the protocol or configured or pre-configured by the network-side device.

[0206] In some embodiments, the downlink channel resources carrying the first indication information or the second indication information have multiple TCI states, each corresponding to a different antenna panel of the terminal; or

[0207] The first indication information or the second indication information is transmitted using multiple downlink channel resources, and the multiple downlink channel resources correspond to different antenna panels of the terminal.

[0208] The downlink channel resources can be physical downlink control channels (PDCCHs). For example, in a specific example, the physical downlink control channel (PDCCH) where the DCI carrying the first indication information is located has multiple active TCI states, each corresponding to a different antenna panel of the terminal; or, the DCI carrying the first indication information is transmitted using multiple PDCCHs, each corresponding to a different antenna panel of the terminal.

[0209] This application provides a method for indicating communication resources, such as... Figure 3 As shown, the method includes:

[0210] Step 201: The network-side device sends a first indication information to the terminal. The first indication information is used to indicate the transmission of a channel or reference signal. The first indication information includes beam information and / or antenna panel information.

[0211] In this embodiment, the network-side device sends a first indication information to the terminal. The first indication information is used to indicate the transmission of a channel or reference signal. The first indication information includes beam information and / or antenna panel information. In this way, when the terminal supports multiple antenna panels, the network-side device can indicate the switching of antenna panels and / or the switching of beams, support data transmission for terminals with multiple antenna panels, and instruct the terminal to select antenna panels and / or switch antenna panels, so that the terminal can select the beam on the optimal antenna panel for transmission and ensure communication performance.

[0212] In some embodiments, the first indication information includes any one of the following:

[0213] Beam information and / or antenna panel information determined based on uplink and downlink performance;

[0214] Beam information and / or antenna panel information determined based on uplink or downlink performance.

[0215] In some embodiments,

[0216] The beam information and / or antenna panel information determined based on uplink and downlink performance includes at least one of the following:

[0217] The beam information is determined based on whether the difference between the first parameter value of the downlink between the current beam and the beam to be switched meets the first preset condition, and whether the difference between the second parameter value of the uplink between the current beam and the beam to be switched meets the second preset condition.

[0218] Antenna panel information is determined based on whether the difference between the third parameter value of the downlink on the currently activated antenna panel and the inactive antenna panel meets the third preset condition, and whether the difference between the fourth parameter value of the uplink on the currently activated antenna panel and the inactive antenna panel meets the fourth preset condition.

[0219] The antenna panel information is determined based on whether the difference between the fifth parameter value of the downlink on the antenna panel where the current beam is located and other antenna panels meets the fifth preset condition, and whether the difference between the sixth parameter value of the uplink on the antenna panel where the current beam is located and other antenna panels meets the sixth preset condition.

[0220] Wherein, the first parameter value is the downlink quality value;

[0221] The second parameter value includes at least one of the following: uplink quality value, transmit power, beam power management - maximum power reduction value.

[0222] The uplink quality value and downlink quality value can be obtained by using any of the following quality parameters or the average value obtained by multiple consecutive measurements of any of the following quality parameters: Reference Signal Received Power (RSRP); Reference Signal Received Quality (RSRQ); Signal-to-Interference-plus-Noise Ratio (SINR); and Received Signal Strength Indication (RSSI).

[0223] The beam information and / or antenna panel information determined by the network-side equipment based on uplink and downlink performance can be determined by, when the terminal supports only one beam transmission, whether the difference in the first downlink parameter value between the current beam and the beam to be switched meets a first preset condition, and whether the difference in the second uplink parameter value between the current beam and the beam to be switched meets a second preset condition. When the terminal only supports one beam transmission, the downlink and uplink beams have beam consistency; that is, the beam information of the terminal's uplink transmit beam and downlink receive beam are the same except for direction. The same applies to the downlink transmit beam and uplink receive beam of the network-side equipment. In other words, the downlink beam and uplink beam correspond to the same beam link. Therefore, if a terminal needs to switch from its current uplink beam to the uplink beam to be switched due to poor uplink quality, then the downlink also needs to be switched from its current downlink beam to the downlink beam to be switched. After the beam switch, the uplink quality may improve, but the downlink quality of the beam may become worse. Therefore, when switching, one cannot only consider uplink quality or downlink quality, but must take both uplink quality and downlink quality into account.

[0224] The antenna panel information determined by the network-side device based on uplink performance and downlink performance can be determined when the terminal supports an active antenna panel, based on whether the difference between the third parameter value of the downlink on the currently active antenna panel and the inactive antenna panel meets a third preset condition, and whether the difference between the fourth parameter value of the uplink on the currently active antenna panel and the inactive antenna panel meets a fourth preset condition. If a terminal can only support one active antenna panel, and the terminal needs to switch from the currently active antenna panel to an inactive one because the uplink quality of the uplink beam on the currently active panel is poor, the terminal will activate the inactive antenna panel to which it needs to switch and deactivate the original active antenna panel. It will then use the uplink beam on the newly activated antenna panel to obtain better uplink quality. In this case, the downlink beam also needs to be switched to the newly activated antenna panel. After the antenna panel switch, the uplink quality may improve, but the downlink quality may become worse. Therefore, when switching antenna panels, it is not possible to consider only the uplink quality or the downlink quality, but to take both uplink quality and downlink quality into account.

[0225] The aforementioned preset conditions can be network-side device configurations or protocol agreements.

[0226] In some embodiments, if the first indication information includes beam information and / or antenna panel information determined by the network-side device based on uplink performance or downlink performance, the beam is either the beam on the currently active antenna panel or the beam on the currently inactive antenna panel.

[0227] In some embodiments, if the channel or reference signal is a non-periodic channel or reference signal, the time offset between the first indication information and the channel or reference signal is greater than or equal to the duration required for beam switching or antenna panel switching.

[0228] In some embodiments, the channel includes at least one of the following: uplink physical shared channel (PUSCH) and downlink physical shared channel (PDSCH);

[0229] The reference signal includes at least one of the following: CSI-RS, SRS.

[0230] In some embodiments, the time offset value is at least one offset value agreed upon by the protocol or configured by the network-side device for beam switching or antenna panel switching.

[0231] In some embodiments, if antenna panel switching is required, the method further includes sending second indication information to the terminal, the second indication information including at least one of the following:

[0232] The network-side device is configured with candidate TCI states or TCI state pools or candidate spatial relationships or spatial relationship pools.

[0233] The network-side device activates a set of TCI states, QCL information, or spatial relationships.

[0234] The TCI status or QCL information or spatial relationship of the channel or reference signal activated or indicated by the network-side device;

[0235] The identification information of the target antenna panel to be switched, indicated by the network-side device.

[0236] The second indication information can be Radio Resource Control (RRC) signaling, Media Access Control (MAC) Control Element (CE) command, or Downlink Control Information (DCI) signaling.

[0237] In some embodiments, the antenna panel information may be determined based on the second indication information in the following ways:

[0238] In method one, the network-side device can configure an information pool corresponding to the antenna panel for the terminal via higher-layer signaling such as RRC signaling. This pool can be called a TCI state pool, a candidate TCI state pool, a spatial relationship pool, or a candidate spatial relationship pool. Each information pool includes multiple TCI states, QCL information, or spatial relationships. If the terminal supports multiple antenna panels, a corresponding information pool is configured for each antenna panel. The network-side device can then activate a set of TCI states, QCL information, or spatial relationships from one information pool via MAC CE, or indicate TCI states, QCL information, or spatial relationships from one information pool via RRC signaling, MAC CE commands, or DCI signaling (such as the first indication information). Alternatively, it can indicate TCI states, QCL information, or spatial relationships from a set of TCI states, QCL information, or spatial relationships activated by the MAC CE. Based on the correspondence between the information pool and the antenna panel, it can be determined which antenna panel of the terminal the channel or reference signal indicated by the first indication information corresponds to, and which antenna panel the network-side device will transmit with.

[0239] Method Two: The information pool configured by the network-side device for the terminal does not correspond to the terminal's antenna panel. When the network-side device activates a set of TCI states, QCL information, or spatial relationships from the information pool using a MAC CE command, the activated set of TCI states, QCL information, or spatial relationships corresponds to the terminal's antenna panel. Then, the network-side device indicates the TCI states, QCL information, or spatial relationships from the set activated by the MAC CE via RRC signaling, a MAC CE command, or DCI signaling (such as the first indication information). Based on the correspondence between the activated set of TCI states, QCL information, or spatial relationships and the antenna panel, it can be determined which antenna panel of the terminal the channel or reference signal indicated by the first indication information corresponds to, and which antenna panel the network-side device will transmit with.

[0240] Method 3: If the information pool configured by the network-side device for the terminal and / or a set of TCI states or QCL information or spatial relationships activated by the network-side device using MAC CE commands do not correspond to the terminal's antenna panel, the network-side device can use RRC signaling or MAC CE commands to activate or DCI signaling to indicate the TCI states or QCL information or spatial relationships. The activated or indicated TCI states or QCL information or spatial relationships correspond to the antenna panel, or the source reference signal in the activated or indicated TCI states or QCL information or spatial relationships corresponds to the antenna panel. Based on this, it can be determined which antenna panel of the terminal the channel or reference signal indicated by the first indication information corresponds to, and which antenna panel the network-side device will transmit with.

[0241] Method 4: The network-side equipment uses RRC signaling, MAC CE command, or DCI signaling to send the identification information of the target antenna panel, and the terminal determines the target antenna panel to be used or switched to based on this information.

[0242] Among them, methods one to three are implicit target antenna panels, and method four is an explicit target antenna panel.

[0243] In some embodiments, the second indication information differs from the first indication information, and the second indication information is sent to the terminal by the network-side device before the first indication information. The terminal determines the antenna panel information based on the second indication information and uses the determined antenna panel to transmit the channel or reference signal indicated by the first indication information to the network-side device.

[0244] In some embodiments, the second instruction information is different from the first instruction information, and the second instruction information is sent to the terminal by the network-side device after the first instruction information.

[0245] The second indication information may include the antenna panel information used for the channel or reference signal transmission indicated by the first indication information, or rewrite the antenna panel information in the first indication information. In the rewriting method, the network-side device uses the second indication information to reconfigure the correspondence between the information pool and the antenna panel, or reactivates another set of TCI states, QCL information, or spatial relationships corresponding to other antenna panels different from those in the first indication information, or reactivates or indicates TCI states, QCL information, or spatial relationships corresponding to other antenna panels different from those in the first indication information, or re-indicates the identification information of other antenna panels different from those in the first indication information. Then, the terminal uses the antenna panel determined by the second indication information to transmit the channel or reference signal with the network-side device.

[0246] In some embodiments, the second indication information is the same as the first indication information, that is, the first indication information carries antenna panel information, such as explicitly carrying an antenna panel identifier, or implicitly determining the antenna panel information through the TCI state or QCL information or spatial relationship corresponding to the antenna panel.

[0247] In some embodiments, if the channel or reference signal indicated by the first indication information corresponds to the antenna panel, then when switching antenna panels, the target antenna panel to be switched can be determined based on the first indication information, and it is not necessary to indicate the target antenna panel to be switched through the second indication information.

[0248] In some embodiments, the second indication information can be carried by the DCI and transmitted between the PDCCH and PDSCH.

[0249] In some embodiments, if the second indication information includes candidate TCI states or TCI state pools or candidate spatial relationships or spatial relationship pools configured by the network-side device,

[0250] The candidate TCI state or TCI state pool or candidate spatial relationship or spatial relationship pool corresponds to an inactive antenna panel, an antenna panel that is currently unused but activated, or an antenna panel other than the antenna panel where the current beam is located.

[0251] In some embodiments, if the second indication information includes a set of TCI states, QCL information, or spatial relationships activated by the network-side device,

[0252] The set of TCI states, QCL information, or spatial relationships corresponds to an inactive antenna panel, an currently unused but activated antenna panel, or an antenna panel other than the one currently containing the beam; or,

[0253] The candidate TCI state or TCI state pool to which the set of TCI states belongs, or the candidate spatial relationship or spatial relationship pool to which the set of spatial relationships belongs, corresponds to an inactive antenna panel, an antenna panel that is currently unused but activated, or an antenna panel other than the antenna panel where the current beam is located.

[0254] In some embodiments, if the second indication information includes the TCI state or QCL information or spatial relationship of the channel or reference signal activated or indicated by the network-side device,

[0255] The TCI status, QCL information, or spatial relationship corresponds to an inactive antenna panel, an currently unused but activated antenna panel, or an antenna panel other than the one currently containing the beam; or,

[0256] The source reference signal in the TCI status, QCL information, or spatial relationship corresponds to an inactive antenna panel, an currently unused but activated antenna panel, or an antenna panel other than the antenna panel where the current beam is located; or,

[0257] The candidate TCI state or TCI state pool to which the TCI state belongs, or the candidate spatial relationship or spatial relationship pool to which the spatial relationship belongs, corresponds to an inactive antenna panel, an currently unused but activated antenna panel, or an antenna panel other than the antenna panel where the current beam is located; or

[0258] The TCI state belongs to a set of TCI states activated by the network-side device, or the spatial relationship belongs to a set of spatial relationships activated by the network-side device, corresponding to an inactive antenna panel, an antenna panel that is currently unused but activated, or an antenna panel other than the antenna panel where the current beam is located.

[0259] In some embodiments, the correspondence between the source reference signal and the antenna panel includes at least one of the following:

[0260] The correspondence between the antenna panel identifier or index configured by the network-side equipment in the configuration information of the reference signal resources and the reference signal resources;

[0261] The correspondence between the antenna panel identifiers or indexes configured on the network-side equipment and the reference signal resource groups.

[0262] In some embodiments, if the terminal only supports one active antenna panel, the channel or reference signal corresponds to the same antenna panel; or, the source reference signal of the TCI state or QCL information or spatial relationship of the channel or reference signal corresponds to the same antenna panel.

[0263] In some embodiments, if the first indication information schedules uplink channel or reference signal transmission, the downlink channel or reference signal uses a default beam; or

[0264] If the first indication information schedules the transmission of the downlink channel or reference signal, the uplink channel or reference signal uses the default beam.

[0265] In this scenario, if the terminal only supports one antenna panel, and the first indication information indicates an uplink switch, such as switching to the uplink beam on another antenna panel, then the downlink beam also needs to be switched to that other antenna panel. Before the other antenna panel receives signaling from the network-side device to update the downlink beam information, the downlink channel or reference signal can use the default beam to ensure communication continuity.

[0266] In some embodiments,

[0267] If the first indication information schedules the transmission of the uplink channel or reference signal, and the third source reference signal in the TCI state or QCL information of the downlink channel or reference signal is the same as or associated with the second source reference signal, then the second source reference signal is the source reference signal in the spatial relationship of the uplink channel or reference signal; or

[0268] If the first indication information schedules the transmission of the uplink channel or reference signal, the downlink channel or reference signal uses the source reference signal in the TCI state or QCL information of the specific control resource set CORESET corresponding to the antenna panel where the uplink channel or reference signal is located; or

[0269] If the first indication information schedules the transmission of the uplink channel or reference signal, the downlink channel or reference signal uses the source reference signal in the TCI state or QCL information of the specific control resource set CORESET with the same TRP identification information as the uplink channel or reference signal; or

[0270] If the first indication information schedules the transmission of the downlink channel or reference signal, and the fifth source reference signal in the spatial relationship of the uplink channel or reference signal is the same as or associated with the fourth source reference signal, then the fourth source reference signal is the source reference signal in the TCI state or QCL information of the downlink channel or reference signal; or

[0271] If the first indication information schedules downlink channel or reference signal transmission, the uplink channel or reference signal uses the source reference signal in the TCI state or QCL information of the specific control resource set CORESET corresponding to the antenna panel where the downlink channel or reference signal is located; or

[0272] If the first indication information schedules the transmission of the downlink channel or reference signal, the uplink channel or reference signal uses the source reference signal in the TCI state or QCL information of the specific control resource set CORESET with the same TRP identification information as the downlink channel or reference signal.

[0273] In some embodiments, the channel or reference signal is transmitted after a duration T, or the first indication information is sent after a duration T.

[0274] In some embodiments, the duration T takes at least one of the following:

[0275] The duration K1 after the network-side device sends the second indication information;

[0282] In some embodiments, the durations K1 and K2 are values ​​agreed upon by the protocol or configured or pre-configured by the network-side device.

[0283] In some embodiments, the downlink channel resources carrying the first indication information or the second indication information have multiple TCI states, each corresponding to a different antenna panel of the terminal; or

[0284] The first indication information or the second indication information is transmitted using multiple downlink channel resources, and the multiple downlink channel resources correspond to different antenna panels of the terminal.

[0285] The downlink channel resource can be a Physical Downlink Control Channel (PDCCH). For example, in a specific example, the PDCCH containing the DCI carrying the first indication information has multiple active TCI states, each corresponding to a different antenna panel of the terminal; or

[0286] The DCI carrying the first indication information is transmitted using multiple PDCCHs, each of which corresponds to a different antenna panel of the terminal.
