Description

Information indication method, terminal equipment and network equipment Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to an information indication method, terminal equipment, and network equipment. Background Art

[0002] Enhanced beam management in Multiple-Input Multiple-Output (MIMO) technology primarily utilizes beamforming to precisely control signal direction, improving signal reception quality and reducing interference. It supports spatial multiplexing, allowing for the simultaneous transmission of multiple data streams, significantly increasing spectral efficiency. This enhanced beam management in MIMO technology significantly enhances the performance of wireless communication systems, including increasing data rates, increasing system capacity, improving signal quality, and reducing interference.

[0003] However, existing beam management programs can only measure the beam to be used at the moment and cannot predict the beam that can be used in a period of time to select the appropriate beam for signaling and data transmission. This causes delays in the beam management program and consumes a lot of resources.

[0045] In order to more clearly illustrate the embodiments of the present disclosure or related technologies, a brief overview of several embodiments will be introduced below. Obviously, these illustrations are only some embodiments of the present disclosure, and people with ordinary skills can derive other illustrations based on these illustrations.

[0046] The present invention relates to the implementation of beam management assisted by a terminal device (e.g., a user equipment (UE)). The terminal device reports information related to the predicted beam, beam management program, and / or predicted time to a network device (e.g., a multiple transmission reception point (TRP) or a base station (BS), specifically a gNB). The network device then schedules the terminal device to perform beam management and measurements based on the information reported by the terminal device. This invention can save resources in the beam management program and reduce the latency of the beam management program.

[0047] The following describes the existing beam management procedures. The beam management procedures can be divided into downlink beam management procedures and uplink beam management procedures. Their specific implementation is described below.

[0048] As shown in Figure 1, the existing downlink beam management includes the following three procedures P-1 to P-3:

[0049] P-1: Used to enable the UE to measure different base station transmit beams to support the selection of base station transmit beam / UE receive beam.

[0050] P-2: Used to enable the UE to measure different base station transmit beams to change the base station's transmit beam.

[0051] P-3: When the UE uses beamforming, it is used to enable the UE to measure the same base station transmit beam to change the UE receive beam.

[0052] Among them, the transmission beam of the base station in P-1 can be a wider beam, and the transmission beam of the base station in P-2 can be a narrower beam.

[0053] The reference signals used for downlink beam management are typically channel state information-reference signal (CSI-RS) and synchronization signal block (SSB). In particular, in the P-1 and P-2 procedures, the base station transmits CSI-RS or SSB using different beams at different times within a scanning cycle. After the UE measures the CSI-RS or SSB within this cycle, the UE sends a channel state information (CSI) report to the base station, where the CSI report includes beam quality information (e.g., CRI / SSBRI-RSRP / SINR). In the P-3 procedure, the base station transmits CSI-RS using the same beam at different times within a scanning cycle. After the UE measures the CSI-RS within this cycle, the UE does not send a CSI report to the base station.

[0054] Refer to Figure 2, which shows an example of CSI-RS measurement and CSI reporting. CSI-RS1 to CSI-RS6 correspond to six different transmit beams sent by the base station at different times within a scanning period. The UE measures these transmit beams, derives the Reference Signal Received Power (RSRP), and then reports a CSI report containing the CSI-RSRP to the base station.

[0055] Accordingly, the existing uplink beam management includes the following three procedures U-1 to U-3:

[0056] U-1: Used to enable the base station to measure different UE transmit beams to support the selection of UE transmit beam / base station receive beam.

[0057] U-2: Used to enable the base station to measure different UE transmit beams to change the base station's receive beam.

[0058] U-3: Used to enable the base station to measure the same UE transmit beam to change the base station receive beam.

[0059] The transmit beam of the UE in U-1 may be a wider beam, and the transmit beam of the UE in U-2 may be a narrower beam.

[0060] The reference signal used for uplink beam management is typically the Sounding Reference Signal (SRS). Specifically, in the U-1 and U-2 procedures, the UE transmits SRS to the base station using different beams at different times within a scanning cycle. After the base station measures the SRS during this cycle, it does not send beam quality information to the UE. In the U-3 procedure, the UE transmits SRS to the base station using the same beam at different times within a scanning cycle. Similarly, after the base station measures the SRS during this cycle, it does not send beam quality information to the UE.

[0061] The motivation and concept of the invention of the embodiments of the present invention are described below.

[0062] In existing beam management procedures, whether for downlink or uplink beam management, the configuration of the reference signal and the configuration reported after measurement (e.g., time-frequency position, period, etc.) are all determined by the base station. Although the base station can obtain the communication quality of the link through CSI reporting and measurement of uplink signals, it is not easy for the base station to perceive changes in link quality in a timely manner. For example, if the UE reports at a long interval, even if the UE knows that the link quality is poor, there is no way to change it. The base station can only wait for the next reporting time to decide whether to adjust the beam. Alternatively, if the UE reports at a short interval, the UE can report in a timely manner, but this will result in a large signaling overhead.

[0063] While base stations can only perceive link quality based on measurement reports, UEs can detect link quality by measuring various other signals (e.g., PDSCH). Furthermore, UEs are more aware of changes in their own position, speed, angle, and other information than base stations. Therefore, UEs can more easily predict changes in link quality and the necessary actions to take in response to these changes. Consequently, UE-triggered beam management procedures can maintain link quality in a timely manner, reduce the probability of dropped calls, and conserve reporting resources.

[0064] Please refer to Figure 3. After completing the beam scanning, the base station and the UE will establish a transmit-receive beam pair for link transmission. After the UE rotates or moves, the previously established transmit-receive beam pair will find it difficult to maintain link transmission. At this point, the base station and the UE need to re-establish the beam pair. Since the base station is not clear about the UE's situation, it needs to go through the P-1, P-2, P-3 and / or U-1, U-2, U-3 processes to establish it, which requires a lot of resources and a long time. Since the UE knows its own situation, it can directly notify the base station of the required process. For example, in the case of rotation, the UE can directly request the P-3 process to establish a beam pair. In the case of movement, the UE can directly request the P-2 and P-3 processes to establish a beam pair.

[0065] Through the above-mentioned beam management triggered by the UE, resources in the beam management program can be saved and the delay of the beam management program can be reduced.

[0066] Figures 4 and 5 are schematic diagrams of a possible network architecture applicable to an embodiment of the present invention, respectively showing a schematic diagram and a functional block diagram of a communication control system 1 according to an embodiment of the present invention. The communication control system 1 includes a terminal device (such as a user equipment UE) 10 and a network device (such as a multiple transmission reception point TRP, a base station BS, specifically eNB, gNB, etc.) 20. The terminal device 10 and the network device 20 can communicate with each other in a wireless or wired manner. The terminal device 10 and the network device 20 can operate on a (New Radio, NR) communication system. The terminal device 10 can communicate with the network device 20 through the NR communication system. The network device 20 and the terminal device 10 can also operate on other communication systems. The network device 20 and the next-generation core network 30 can communicate with each other in a wireless or wired manner. When the communication control system 1 complies with the new radio standard of the 3rd Generation Partnership Project (3GPP), the next generation core network (5GCN) 30 is a back-end service network system and may include network entities such as user plane function (UPF), session management function (SMF), access and mobility management function (AMF), unified data management (UDM), policy control function (PCF), control plane (CP) / user plane (UP) separation (CP / UP separation, CUPS), authentication server function (AUSF), network slice selection function (NSSF), and network exposure function (NEF).

[0067] Terminal device 10 includes a transceiver 12 and a processor 14 electrically connected to each other. Network device 20 includes a transceiver 22 and a processor 24 electrically connected to each other. Transceiver 12 of terminal device 10 is used to send signals to network device 20, which processor 24 of network device 20 processes the signals. Transceiver 22 of network device 20 is used to send signals to terminal device 10, which processor 14 of terminal device 10 processes the signals. In this way, terminal device 10 and network device 20 communicate with each other. Processors 14 and 24 may each further include a memory operable to store various programs and information required to operate the connected processors. The memory may be, for example, read-only memory (ROM), random access memory (RAM), flash memory, a memory card, a storage medium, or other storage device. Processors 14 and 24 may include a general-purpose central processing unit (CPU), an application-specific integrated circuit (ASIC), other chipsets, logic circuits, and / or data processing devices. Transceivers 12 and 22 may include baseband circuitry and radio frequency (RF) circuitry for processing radio frequency signals. When these embodiments are implemented in software, the techniques described herein can be implemented through modules, procedures, functions, entities, etc. that perform the functions described herein. These modules can be stored in a memory and executed by a processor. The memory can be implemented within the processor or external to the processor, in which case components that can be communicatively coupled to the processor in various ways are known in the art.

[0068] Figure 6A shows a flowchart of an information indication method 100 according to one embodiment of the present invention, and Figure 6B shows a flowchart of an information indication method 200 according to another embodiment of the present invention. Referring to Figures 6A and 6B, the information indication method 100 shown in Figure 6A includes steps 110 and 130, while the information indication method 200 shown in Figure 6B includes steps 110, 120, 130, and 140. In other words, the information indication method of the present invention can be supplemented with steps 120 and 140 based on the method shown in Figure 6A. These steps are optional and not required in the present invention. Methods 100 and 200 can be executed on a terminal device, and can be executed by the processor 14 and transceiver 12 of the terminal device 10 in Figure 5 in cooperation with each other. It is understood that the network device 20 can also execute the channel measurement methods corresponding to methods 100 and 200, which will not be described in detail here.

[0069] Step 110: Receive configuration information.

[0070] In this step, the network device sends configuration information to the terminal device, and the terminal device receives the configuration information from the network device. The configuration information can be configured via Radio Resource Control (RRC) signaling. The configuration information includes at least one of the following: resources for reported beam-related information, beam management procedures, configuration related to the indicated beam, and configuration related to the time offset.

[0071] The resources for the reported beam-related information refer to the resources required by the terminal device to report beam-related information (such as predicted beam information) in subsequent steps. The resource configuration of the reported beam-related information may include physical uplink control channel (PUCCH) configuration or physical uplink shared channel (PUSCH) configuration. The terminal device can report beam-related information to the network device through the configured PUCCH resources or PUSCH resources.

[0072] The beam management procedure may be configured by RRC or predefined. The configuration of the beam management procedure may be a downlink beam scanning procedure, an uplink beam scanning procedure, or both. The downlink beam scanning procedure may include the P-1 to P-3 procedures mentioned above, and the uplink beam scanning procedure may include the U-1 to U-3 procedures mentioned above. The network device may configure the available beam scanning procedures to the terminal device, and the terminal device may indicate to the network device in subsequent steps which beam scanning procedure or procedures to perform.

[0073] Specifically, the downlink beam scanning procedure may include at least one of the following:

[0074] (P-1) Network devices use different beams to transmit, and terminal devices use different beams to receive;

[0075] (P-2) Network devices use different beams to transmit, and terminal devices use the same beam to receive;

[0076] (P-3) Network devices use the same beam to transmit, and terminal devices use different beams to receive.

[0077] The uplink beam scanning procedure may include at least one of the following:

[0078] (U-1) The terminal device uses different beams to transmit, and the network device uses different beams to receive;

[0079] (U-2) The terminal device uses different beams to transmit, and the network device uses the same beam to receive;

[0080] (U-3) The terminal device uses the same beam to transmit, and the network device uses a different beam to receive.

[0081] Among them, the relevant configuration of the indicator beam may include one or more of the following: channel state information (CSI) reporting configuration, channel state information-reference signal (CSI-RS) resource configuration, sounding reference signal (SRS) resource configuration, transmission configuration indication (TCI) status configuration, and spatial relationship configuration. Specifically, the CSI reporting configuration may include a CSI reporting configuration list, and the terminal device may indicate one or more CSI reporting configurations in the list to the network device in subsequent steps to indicate the beams corresponding to the one or more CSI reporting configurations; the CSI-RS resource configuration may include a CSI-RS resource set list, and the terminal device may indicate one or more CSI-RS resource sets in the list to the network device in subsequent steps to indicate the beams corresponding to the one or more CSI-RS resource sets; the SRS resource configuration may include an SRS resource set list, and the terminal device may indicate one or more SRS resource sets in the list to the network device in subsequent steps to indicate the beams corresponding to the one or more SRS resource sets; the TCI state configuration may include a TCI state list, and the terminal device may indicate one or more TCI states in the list to the network device in subsequent steps to indicate the beams corresponding to the one or more TCI states; the spatial relationship configuration may include a spatial relationship list, and the terminal device may indicate one or more spatial relationships in the list to the network device in subsequent steps to indicate the beams corresponding to the one or more spatial relationships.

[0082] The time offset configuration can be used by a terminal device to indicate information related to the time offset. The time offset indicates the time at which the beam or beam scanning procedure indicated by the terminal device applies. The starting point of the time offset information can be the time when the terminal device reports the beam-related information, and the end point of the time offset information can be the time when the beam-related information applies. For example, a network device can be configured with multiple time offsets, such as t1, t2, ..., t10, and a terminal device can report one of these time offsets to indicate the time offset.

[0083] Step 120: Poor link quality or own motion is detected, and beam-related information is predicted.

[0084] In this step, the terminal device detects the signal quality of the link. When the signal quality is below a threshold, it predicts beam-related information. If the terminal device detects that the quality of the currently used beam is poor, it can report other beams to the network device for data transmission, or report the beam scanning program to the network device to reselect the beam. The reported beam-related information (such as beam indication information, beam management program information, and time offset information) can be predicted by the terminal device based on historical data. For example, one or more beams that have achieved better link quality over a period of time can be used as predicted beams.

[0085] Alternatively, the terminal device detects the state of the terminal device, and when the state is in motion (such as rotation, movement), the information related to the beam is predicted. When the terminal device is in a rotating or moving state, the transmit and receive beam pair originally used to communicate with the network device may become inapplicable. Since the terminal device can predict the state of its own movement at the next point in time, the terminal device can predict the beam that can obtain better link quality at a certain point in time during the movement, or which beam scanning program or programs can obtain a better beam at that point in time. For example, when the terminal device is in a rotating state, the angle of rotation from the first time point to the second time point can be used to predict the beam that is suitable for use at the second time point. For another example, when the terminal device is in a moving state, the distance moved from the first time point to the second time point can be used to predict the beam that is suitable for use at the second time point.

[0086] It's important to note that this step isn't mandatory. In some cases, this step can be omitted. For example, a terminal device can periodically or aperiodically report beam-related information, allowing the network device to select the appropriate beam for data transmission or select the appropriate beam management program to select the optimal beam based on the reported beam-related information. Therefore, this step can be omitted.

[0087] Step 130: Report beam-related information.

[0088] In this step, in response to the configuration information, the terminal device reports beam-related information to the network device, where the beam-related information includes at least one of the following: beam indication information, beam management program information, and time offset information.

[0089] The beam indication information is used to indicate one or more beams to the network device, which may be a wide beam or one or more narrow beams within a wide beam. For example, the beam indication information may indicate a beam that can achieve better link quality at a certain point in time. The beam indication information may include at least one of the following:

[0090] Channel state information (CSI) reporting configuration;

[0091] Channel State Information-Reference Signal (CSI-RS) resource set;

[0092] Sounding Reference Signal (SRS) resource set;

[0093] Transmission Configuration Indication (TCI) status; and

[0094] Spatial relationship.

[0095] Specifically, the beam indication information may indicate one or more CSI reporting configurations in the CSI reporting configuration list to indicate the beam corresponding to the one or more CSI reporting configurations; the beam indication information may indicate one or more CSI-RS resource sets in the CSI-RS resource set list to indicate the beam corresponding to the one or more CSI-RS resource sets; the beam indication information may indicate one or more SRS resource sets in the SRS resource set list to indicate the beam corresponding to the one or more SRS resource sets; the beam indication information may indicate one or more TCI states in the TCI state list to indicate the one or more TCI states; the beam indication information may indicate one or more spatial relationships in the spatial relationship list to indicate the beam corresponding to the one or more spatial relationships.

[0096] The beam management program information may include one or more of the following: beam scanning program P-1, beam scanning program P-2, beam scanning program P-3, beam scanning program U-1, beam scanning program U-2, and beam scanning program U-3. In other words, a terminal device may report one or more beam scanning programs to instruct the network device to determine the optimal transmit / receive beam pair based on the reported one or more beam scanning programs.

[0097] The time offset information indicates the time at which the beam or beam scanning procedure indicated by the terminal device is used. For example, the terminal device may report a time offset to indicate the time offset.

[0098] The channel for transmitting beam-related information may be PUCCH or PUSCH. The indication of beam-related information may be in the form of a bitmap, an identifier (ID), a combined identifier, or a MAC CE, which will be described in detail later.

[0099] Step 140: Schedule measurement signals.

[0100] In this step, the network device schedules a corresponding measurement signal (e.g., a reference signal) based on the reported information of the terminal device (i.e., beam-related information). The terminal device receives the scheduled reference signal, wherein the reference signal is included in the beam-related information in step 130. For example, the terminal device reports one or more predicted beams, and the network device sends a reference signal corresponding to the one or more predicted beams, so that the terminal device can measure the reference signal and report the measurement result. For another example, the terminal device reports one or more beam scanning programs, and the network device schedules a corresponding measurement signal for the beam scanning programs reported by the terminal device.

[0101] It should be noted that this step is not mandatory. In some cases, this step may not be performed. For example, the network device can select the corresponding beam for data transmission based on the reported beam-related information, so this step can be omitted.

[0102] In the information indication method of an embodiment of the present invention, a terminal device reports beam-related information, which includes at least one of the following: beam indication information, beam management program information, and time offset information. This implements terminal-assisted beam management. Based on the information reported by the terminal device regarding the predicted beam, beam management program, and / or predicted time, the network device schedules the terminal device to perform beam management and measurement, thereby conserving resources in the beam management program and reducing latency in the beam management program.

[0103] To further illustrate the method shown in FIG. 6 , some exemplary methods are described in detail below.

[0104] Please refer to Figure 7, which shows a schematic diagram of beam management when the UE is mobile. Beams 1-5 of a network device (e.g., a base station) are beams for different SSBs or CSI-RSs (typically periodic). Base station beams 41-43 are beams for different CSI-RSs (typically semi-persistent or aperiodic). Beams 1-2 of a terminal device (e.g., a UE) are different receive beams. CSI-RSs 41-43 are quasi-co-located with SSB 4.

[0105] At a first moment (e.g., moment t0), the UE is under the coverage of the first beam (e.g., SSB 2) of the base station, and the UE predicts that it will move to the coverage of the second beam (e.g., SSB 4) later (e.g., moment t1).

[0106] The UE reports beam-related information (e.g., beam prediction information) to the base station at a first moment. The beam-related information may be at least one of the following:

[0107] -CSI reporting configuration 4, time offset t1-t0 (if any)

[0108] -CSI-RS resource set 4, time offset t1-t0 (if any)

[0109] -TCI state 4, beam management procedure P-2, time offset t1-t0 (if any).

[0110] CSI reporting configuration 4 includes CSI-RS resource set 4, which contains CSI-RS resources (CSI-RS 41, CSI-RS 42, and CSI-RS 43) that are quasi-co-located with SSB 4. The repetition parameter of the CSI-RS resource set is set to off (this means that CSI-RS 41, CSI-RS 42, and CSI-RS 43 use different downlink spatial filters). This reporting information indicates that the UE is interested in performing beam refinement on base station beam 4.

[0111] The source reference signal for QCL Type D in TCI state 4 is SSB 4 or CSI-RS 4. Combined with the beam management procedure P-2 information, this also means that the UE is interested in performing beam refinement on base station beam 4.

[0112] The time offset t1-t0 means that the UE is interested in beam management at the time point t1-t0 after the report.

[0113] After the UE reports the beam-related information, the base station can send activation information (e.g., DCI or MAC CE) to trigger beam measurement and reporting at time t1. At time t1, the UE will use the same beam to receive CSI-RS 41-43 sent by the base station and report the measurement results of CSI-RS 41-43. This allows the base station to obtain the optimal transmit beam (e.g., CSI-RS 42). By further performing beam management procedure P-3, the UE can obtain the optimal receive beam.

[0114] In the case where the UE is moving, the specific process of the above-mentioned beam management is shown in Figure 8. Please refer to Figure 8. In step 210, the base station sends configuration information to the UE through RRC signaling. This step can refer to step 110 above and will not be repeated here. In step 220, the UE reports beam-related information (such as beam prediction information) to the base station at a first moment (for example, moment t0). The beam-related information is, for example, CSI reporting configuration 4, and its repetition parameter is set to off. In step 230, the base station sends activation information to trigger beam measurement and reporting at the second moment (for example, moment t1). In step 240, at the second moment, the UE receives CSI-RS 41-43 sent by the base station with the same beam. In step 250, the UE reports the measurement results of CSI-RS 41-43. Through the above-mentioned UE-triggered beam management, resources in the beam management program can be saved and the delay of the beam management program can be reduced.

[0115] Please refer to Figure 9, which shows a schematic diagram of beam management when the UE is rotating. Beams 1-5 of a network device (e.g., a base station) are beams for different SSBs or CSI-RS (typically periodic). Beams 21-23 of the base station are beams for different CSI-RS (typically semi-persistent or aperiodic). Beams 1-2, 11, and 21-23 of a terminal device (e.g., a UE) are different receive beams. CSI-RSs 21-23 are quasi-co-located with SSB 2.

[0116] At the first moment (for example, moment t0), the communication beam pair between the UE and the base station is CSI-RS 21 and receiving beam 11, and the UE predicts that it will rotate by a certain angle (for example, 60 degrees) later (for example, moment t1).

[0117] The UE reports beam-related information (e.g., beam prediction information) to the base station at a first moment. The beam-related information may be at least one of the following:

[0118] -CSI reporting configuration 2, time offset t1-t0 (if any)

[0119] -CSI-RS resource set 2, time offset t1-t0 (if any)

[0120] -TCI state 2, beam management procedure P-3, time offset t1-t0 (if any).

[0121] CSI reporting configuration 2 includes CSI-RS resource set 2, which includes CSI-RS resources (CSI-RS 21, CSI-RS 22, and CSI-RS 23) that are quasi-co-located with SSB 2 or CSI-RS 21, and the repetition parameter of the CSI-RS resource set is set to on (this means that CSI-RS 21, CSI-RS 22, and CSI-RS 23 use the same downlink spatial filter). This reporting information indicates that the UE is interested in performing beam refinement on the UE beam.

[0122] The source reference signal for QCL Type D in TCI state 2 is SSB 2 or CSI-RS 21. Combined with the beam management procedure P-3 information, it also means that the UE is interested in beam refinement of the UE beam.

[0123] The time offset t1-t0 means that the UE is interested in beam management at the time point t1-t0 after the report.

[0124] After the UE reports the beam-related information, the base station can send activation information (e.g., DCI or MAC CE) to trigger beam measurement and reporting at time t1. At time t1, the UE will receive CSI-RS 21-23 sent by the base station using different beams (e.g., UE beams 21-23). ​​This allows the UE to obtain the optimal receive beam.

[0125] In the case where the UE rotates, the specific process of the above-mentioned beam management is shown in Figure 10. Please refer to Figure 10. In step 310, the base station sends configuration information to the UE through RRC signaling. This step can refer to step 110 above and will not be repeated here. In step 320, the UE reports beam-related information (such as beam prediction information) to the base station at a first moment (for example, moment t0). The beam-related information is, for example, CSI reporting configuration 2, and its repetition parameter is set to on. In step 330, the base station sends activation information to trigger beam measurement and reporting at the second moment (for example, moment t1). In step 340, at the second moment, the UE receives CSI-RS 21-23 sent by the base station with different beams (for example, UE beams 21-23), so that the UE can obtain the best receiving beam. Through the above-mentioned UE-triggered beam management, resources in the beam management program can be saved and the delay of the beam management program can be reduced.

[0126] In some embodiments, the configuration information includes a CSI reporting configuration list, the CSI reporting configuration list includes one or more CSI reporting configurations, and the beam indication information is indicated in at least one of the following ways: indicating one or more selected CSI reporting configurations to the network device in the form of a bitmap; indicating one or more selected CSI reporting configurations to the network device in the form of an identifier; indicating one or more selected CSI reporting configurations to the network device in the form of a combined identifier; or indicating one or more selected CSI reporting configurations to the network device via a MAC CE. The bits in the bitmap correspond one-to-one to the CSI reporting configurations, the total number of bits in the bitmap corresponds to the number of CSI reporting configurations, and each bit in the bitmap indicates whether the corresponding CSI reporting configuration is selected. One identifier corresponds to one selected CSI reporting configuration. One combined identifier corresponds to one or more selected CSI reporting configurations. The MAC CE includes at least an area for the CSI reporting configurations, and the number of bits in the area for the CSI reporting configurations is related to the number of CSI reporting configurations. The CSI reporting configuration indicates one or more downlink beam sets that the UE is interested in. The UE does not need to traverse and measure all downlink beams, which saves downlink resources and reduces latency.

[0127] To further illustrate the method in the above embodiment, an exemplary method is described in detail below:

The MAC CE includes at least a CSI-RS resource set region, and the number of bits in the CSI-RS resource set region is related to the number of CSI-RS resource sets. The reporting of the CSI-RS resource set indicates one or more downlink beam sets that the UE is interested in.

[0167] To further illustrate the method in the above embodiment, an exemplary method is described in detail below:

[0168] RRC Configuration

[0169] The above configuration information can be configured through RRC signaling. RRC configures a TCI state list, which contains a number of TCI states, assuming M. Each TCI state has a TCI state ID, and each TCI state is associated with at least one CSI-RS, SSB, or SRS with a QCL type of D.

[0170] Furthermore, / or alternatively, RRC configures the number of TCI states that can be reported, assuming it is M. When reporting in bitmap form, M may not be configured. When reporting in other forms, if M is not configured, it defaults to 1.

[0171] UE report

[0172] Method 1: The UE reports one or more selected TCI states using a bitmap on the PUCCH or PUSCH. The total number of bits in the bitmap is equal to the total number of TCI states in the TCI state list configured by RRC. Each bit in the bitmap indicates whether the corresponding TCI state is selected, as shown in Figure 18. For example, the bitmap reported by the UE is '00010010', indicating that there are a total of 8 TCI states, and the UE reports the second and fifth TCI states.

[0173] In the unified TCI framework, the TCI state indicated by the joint TCI state can be associated with both downlink and uplink beams. Therefore, a bit is required in the bitmap to indicate downlink or uplink, as shown in Figure 19.

[0174] Method 2: The UE reports one or more selected TCI state IDs on PUCCH or PUSCH. The total number of bits required for each reported TCI state ID is equal to As shown in Table 10.

The total number of TCI state ID areas in the MAC CE in part (b) of Figure 20 is predefined or configured by RRC, and the total number of bits of each reported TCI state ID area is related to the total number of TCI states in the TCI state list configured by RRC. The number of TCI state combination ID areas in the MAC CE in part (c) of Figure 20 is equal to 1, and its bit number is equal to

[0184] For the unified TCI framework, a single bit is required in the MAC CE to indicate downlink or uplink for the combined TCI status. Therefore, the MAC CE contains at least one of the following fields: cell ID, BWP ID, TCI status information, and transmission direction information (i.e., uplink or downlink). Figure 21 shows three MAC CE designs.

[0185] In some embodiments, the configuration information includes a spatial relationship list, which includes one or more spatial relationships. The beam indication information is indicated in at least one of the following ways: indicating one or more selected spatial relationships to the network device in the form of a bitmap; indicating one or more selected spatial relationships to the network device in the form of an identifier; indicating one or more selected spatial relationships to the network device in the form of a combined identifier; indicating one or more selected spatial relationships to the network device through a MAC CE.

The reporting of the spatial relationship indicates one or more uplink beams of interest to the UE. The base station does not need to traverse and measure all uplink beams, thereby saving uplink resources and reducing latency.

[0186] To further illustrate the method in the above embodiment, an exemplary method is described in detail below:

[0187] RRC Configuration

[0188] The above configuration information can be configured through RRC signaling. RRC configures a spatial relationship list, which contains several spatial relationships, assuming there are M. Each spatial relationship has a spatial relationship ID, and each spatial relationship is associated with a CSI-RS, SSB or SRS.

[0189] Furthermore / or alternatively, the number of spatial relationships that can be reported by RRC configuration is assumed to be M. When reporting in bitmap form, M may not be configured. When reporting in other forms, if M is not configured, M defaults to 1.

[0190] UE reports

[0191] Method 1: The UE reports one or more selected spatial relationships using a bitmap on the PUCCH or PUSCH. The total number of bits in the bitmap is equal to the total number of spatial relationships in the RRC-configured spatial relationship list.

[0192] Method 2: The UE reports one or more selected spatial relationship IDs on PUCCH or PUSCH. The number of bits required for each reported spatial relationship ID is equal to As shown in Table 15.

[0193] Table 15

[0194] Method 3: The UE reports a combination ID on PUCCH or PUSCH. Each combination ID corresponds to the selected M spatial relationships, as shown in Table 16. The number of bits of the reported combination ID is equal to As shown in Table 17, It represents the number of combinations of selecting M from N.

[0195] Table 16

[0196] Table 17

[0197] Method 4: The UE reports one or more selected spatial relationships in the form of MAC CE on PUSCH. The MAC CE contains at least one of the following areas: cell ID, BWP ID, and spatial relationship information. Figure 23 shows the design of two MAC CEs. The number of T areas in the MAC CE in part (a) of Figure 23 is determined by the total number of spatial relationship configurations in the spatial relationship list configured by RRC, and each spatial relationship configuration in the list is mapped to each T area in sequence. The total number of spatial relationship configuration ID areas in the MAC CE in part (b) of Figure 23 is predefined or configured by RRC, and the total number of bits of each reported spatial relationship configuration ID area is related to the total number of spatial relationship configurations in the spatial relationship configuration list configured by RRC. The number of spatial relationship combination ID areas in the MAC CE in part (c) of Figure 23 is equal to 1, and its bit number is equal to

[0198] In some embodiments, the beam management program is indicated in at least one of the following ways: indicating one or more selected beam management programs to the network device in the form of a bitmap; indicating one or more selected beam management programs to the network device in the form of an identifier; indicating one or more selected beam management programs to the network device in the form of a combined identifier; or indicating one or more selected beam management programs to the network device via a MAC CE.

One identifier corresponds to one selected beam management program. One combined identifier corresponds to one or more selected beam management programs. The MAC CE includes at least a beam management program area, and the number of bits in the beam management program area is related to the number of beam management programs. Reporting the beam management program explicitly indicates the beam management program of interest to the UE, eliminating the need for the base station and / or UE to execute other beam management programs, saving resources and reducing latency.

[0199] To further illustrate the method in the above embodiment, an exemplary method is described in detail below:

[0200] UE reports

[0201] Method 1: The UE reports one or more selected beam management programs in the form of a bitmap on the PUCCH or PUSCH.

[0202] Example 1: The total number of bits in the bitmap is equal to the number of downlink or uplink beam management procedures. Each bit in the bitmap indicates whether the corresponding beam management procedure is selected. Whether the beam management procedure indicated by the bitmap is downlink or uplink can be predefined or configured by RRC. Generally, there are three downlink or uplink beam management procedures, so the total number of bits in the bitmap is equal to three, as shown in Figure 24.

[0203] Table 18 shows how the downlink beam management procedure corresponds to the reported bitmap. The uplink beam management procedure is similar, except that P-1, P-2, and P-3 are replaced with U-1, U-2, and U-3.

[0204] Table 18

[0205] Example 2: The total number of bits in the bitmap is equal to the number of downlink or uplink beam management procedures plus the number of downlink or uplink indicators. A portion of the bits in the bitmap are used to indicate whether the downlink or uplink is selected, while each bit in the other portion is used to indicate whether the corresponding beam management procedure is selected. Typically, there are three downlink or uplink beam management procedures and one downlink or uplink indicator, so the total number of bits in the bitmap is four, as shown in Figure 25.

[0206] The example in Table 19 shows how the downlink beam management procedure corresponds to the reported bitmap.

[0207] Table 19

[0208] Example 3: The total number of bits in the bitmap is equal to the number of downlink and uplink beam management programs. Each bit in the bitmap indicates whether the corresponding beam management program is selected. Generally, there are 6 downlink and uplink beam management programs, so the total number of bits in the bitmap is equal to 6, as shown in Figure 26.

[0209] Table 20 shows how the downlink beam management procedure and the reported bitmap correspond. As can be seen, the UE can report the downlink or uplink beam management procedure separately, or report the downlink and uplink beam management procedures simultaneously.

[0210] Table 20

[0211] Method 2: The UE reports one or more selected downlink or uplink beam management program IDs on the PUCCH or PUSCH.

[0212] Example 1: The correspondence between downlink beam management procedures and IDs is shown in Table 21. Each downlink beam management procedure corresponds to one ID, which is used to number the individual downlink beam management procedures. This correspondence can be predefined or configured by RRC. The uplink beam management procedure is similar, except that P-1, P-2, and P-3 are replaced with U-1, U-2, and U-3.

[0213] Table 21

[0214] The UE only reports one or more downlink or uplink beam management program IDs. The total number of downlink or uplink beam management program IDs that the UE can report is predefined or configured by RRC, assuming it is N. Assuming the total number of downlink or uplink beam management program IDs is M, the total number of bits required for each reported TCI state ID is equal to In this example, there are three downlink or uplink beam managers, so M will be equal to 3 and N will be less than or equal to 3. The number of bits required for each reported beam manager ID is 2, as shown in Table 22.

[0215] Table 22

[0216] The example in Table 23 shows the correspondence between the indication bits reported by the UE and the beam management procedure.

[0217] Table 23

[0218] Furthermore, some bits can be added to the indication bit in Example 1 to indicate whether the beam management procedure is downlink or uplink. The example in Table 24 shows that one bit is added to the least significant bit of the indication bit to indicate downlink or uplink.

[0219] Table 24

[0220] Example 2: The correspondence between downlink and uplink beam management procedures and IDs is shown in Table 25. Each downlink and uplink beam management procedure corresponds to one ID, i.e., each downlink and uplink beam management procedure is numbered. This correspondence can be predefined or configured by RRC.

[0221] Table 25

[0222] The UE only reports one or more downlink and uplink beam management program IDs. The total number of downlink and uplink beam management program IDs that the UE can report is predefined or configured by RRC, assuming it is N. Assuming the total number of downlink or uplink beam management program IDs is M, the total number of bits required for each reported TCI state ID is equal to In this example, the total number of downlink and uplink beam managers is 6, so M will be equal to 6 and N will be less than or equal to 6. The number of bits required for each reported beam manager ID is 3, as shown in Table 26.

[0223] Table 26

[0224] The example in Table 27 shows the correspondence between the indication bits reported by the UE and the beam management procedure.

[0225] Table 27

[0226] Example 3: The correspondence between downlink beam management procedures and combination IDs is shown in Table 28. Single and multiple downlink beam management procedures are assigned a combination ID, which numbers the single and multiple downlink beam management procedures. This correspondence can be predefined or configured by RRC. The uplink beam management procedure is similar, except that P-1, P-2, and P-3 are replaced with U-1, U-2, and U-3.

[0227] Table 28

[0228] The UE reports only one of the downlink or uplink beam management program combination IDs. Assuming that the total number of downlink or uplink beam management program combination IDs is M, the total number of bits required to report the beam management program combination ID is equal to In this example, there are 7 downlink or uplink beam managers, so M is equal to 6. The number of bits required for the reported beam manager combination ID is 3.

[0229] The example in Table 29 shows the correspondence between the indication bits reported by the UE and the beam management procedure.

[0230] Table 29

[0231] Some bits can be added to the indication bits in Example 3 to indicate whether the beam management procedure is downlink or uplink. The example in Table 30 shows that one bit is added to the least significant bit of the indication bits to indicate downlink or uplink.

[0232] Table 30

[0233] Example 4: The correspondence between downlink and uplink beam management procedures and combination IDs is shown in Table 31. Single and multiple downlink and uplink beam management procedures correspond to one combination ID, that is, the single and multiple downlink and uplink beam management procedures are numbered. This correspondence can be predefined or configured by RRC.

[0234] Table 31

[0235] The UE reports only one of the downlink and uplink beam management program combination IDs. Assuming that the total number of downlink or uplink beam management program combination IDs is M, the total number of bits required to report the beam management program combination ID is equal to In this example, there are 63 downlink or uplink beam management programs, so M is equal to 63. The number of bits required for each reported beam management program combination ID is 6.

[0236] The example in Table 32 shows the correspondence between the indication bits reported by the UE and the beam management procedure.

[0237] Table 32

[0238] Method 3: The UE reports one or more selected beam management programs in the form of a MAC CE on the PUSCH. The MAC CE contains at least one of the following areas: cell ID, BWP ID, and beam management program information. Figure 27 shows the design of two MAC CEs. The number of T areas in the MAC CE in part (a) of Figure 27 is determined by the total number of beam management programs configured by RRC, and each spatial relationship configuration in the list is mapped to each T area in sequence. The total number of beam management program ID areas in the MAC CE in part (b) of Figure 27 is predefined or configured by RRC, and the total number of bits in each reported spatial relationship configuration ID area is related to the total number of spatial relationship configurations in the spatial relationship configuration list configured by RRC.

[0239] If the UE only reports beam management procedure information, the base station does not know the beam information, so default beam information needs to be defined. The default beam can be defined as the beam corresponding to the RS in the TCI state or spatial relationship indicated by the current base station to the UE, and / or the beam corresponding to the RS quasi-co-located with the RS in this TCI state or spatial relationship, and / or the L adjacent beams of the beam corresponding to the RS in this TCI state or spatial relationship, where L can be predefined for different beam management procedures or configured by RRC.

[0240] For example, in Figure 7, assuming that the beam currently indicated by the UE is CSI-RS 2 and L=2, if the UE reports P-1, the default beam is CSI-RS 1-3, which means that the UE is interested in scanning these beams; assuming that the beam currently indicated by the UE is CSI-RS 2 and L=1, if the UE reports P-2, the default beam is CSI-RS 2, which means that the UE is interested in performing base station beam refinement on this beam; in Figure 9, assuming that the beam currently indicated by the UE is CSI-RS 21, if the UE reports P-3, the default beam is CSI-RS 21, which means that the UE is interested in performing UE beam refinement on this beam.

[0241] In some embodiments, the configuration information includes a TCI state list, which includes one or more TCI states. The beam-related information includes beam indication information and beam management program information, which is indicated in at least one of the following ways: indicating one or more selected TCI states and one or more selected beam management programs to the network device in the form of a bitmap; indicating one or more selected TCI states and one or more selected beam management programs to the network device in the form of an identifier; indicating one or more selected TCI states and one or more selected beam management programs to the network device in the form of a combined identifier; or indicating one or more selected TCI states and one or more selected beam management programs to the network device via a MAC CE. Some bits in the bitmap correspond one-to-one to TCI states, other bits in the bitmap correspond one-to-one to beam management programs, the total number of bits in the bitmap corresponds to the number of TCI states and beam management programs, and each bit in the bitmap indicates whether the corresponding TCI state or beam management program is selected. One identifier corresponds to one selected TCI state or one selected beam management program, and one combined identifier corresponds to one or more selected TCI states or one or more selected beam management programs. The MAC CE includes at least an area for TCI status and an area for beam management programs, wherein the number of bits in the TCI status area is related to the number of TCI states, and the number of bits in the beam management program area is related to the number of beam management programs. In other embodiments, the configuration information includes a spatial relationship list, the spatial relationship list includes one or more spatial relationships, and the beam-related information includes beam indication information and beam management program information, which is indicated in at least one of the following ways: indicating one or more selected spatial relationships and one or more selected beam management programs to the network device in the form of a bitmap; indicating one or more selected spatial relationships and one or more selected beam management programs to the network device in the form of an identifier; indicating one or more selected spatial relationships and one or more selected beam management programs to the network device in the form of a combined identifier; indicating one or more selected spatial relationships and one or more selected beam management programs to the network device through a MAC CE. Some bits in the bitmap correspond one-to-one to spatial relationships, other bits in the bitmap correspond one-to-one to beam management programs, the total number of bits in the bitmap corresponds to the number of spatial relationships and beam management programs, and each bit in the bitmap indicates whether the corresponding spatial relationship or beam management program is selected. One identifier corresponds to one selected spatial relationship or one selected beam management program. One combined identifier corresponds to one or more selected spatial relationships or one or more selected beam management programs.The MAC CE includes at least a spatial relationship area and a beam management procedure area. The number of bits in the spatial relationship area is related to the number of spatial relationships, and the number of bits in the beam management procedure area is related to the number of beam management procedures. The combination of the TCI status and beam management procedure more clearly indicates the beams and beam management procedures of interest to the UE.

[0242] To further illustrate the method in the above embodiment, an exemplary method is described in detail below:

[0243] UE report

[0244] Method 1: The UE reports one or more selected TCI states or spatial relationships, as well as one or more beam management procedures, in the form of a bitmap on the PUCCH or PUSCH. A portion of the bits in the bitmap indicates whether the TCI state or spatial relationship is selected, while another portion indicates whether the beam management procedure is selected. The number of bits for the TCI state or spatial relationship and beam management procedure is consistent with the previous discussion, as shown in Figure 28. For the joint TCI state in the unified TCI framework, the joint TCI state can also be associated with the uplink beam management procedure.

[0245] Method 2: The UE reports one or more selected TCI state IDs or spatial relationship IDs, and one or more beam management procedure IDs on the PUCCH or PUSCH. The number of bits of the TCI state or spatial relationship ID and beam management procedure ID is consistent with the previous discussion, as shown in Table 33.

[0246] Table 33

[0247] Method 3: The UE reports the selected one or more spatial relationships and one or more beam management procedures in the form of MAC CE on PUSCH. The MAC CE contains at least one of the following areas: cell ID, BWP ID, TCI status or spatial relationship information, and beam management procedure information. Figure 29 shows the design of two MAC CEs. In the MAC CE in part (a) of Figure 29, the T area indicates whether the TCI status or spatial relationship is selected, and the S area indicates whether the beam management procedure is selected. The number of bits in the area indicating the TCI status or spatial relationship information and the beam management procedure information in the MAC CE is consistent with the previous discussion. Parts (b) and (c) of Figure 29 illustrate the schemes indicated by the identifier (ID) and the combined ID, respectively.

[0248] In some embodiments, the configuration information includes a TCI state list, which includes one or more TCI states. The beam-related information includes beam indication information and preset parameters (e.g., a repetition parameter), which are indicated in at least one of the following ways: indicating one or more selected TCI states and preset parameters to the network device in the form of a bitmap; indicating one or more selected TCI states and preset parameters to the network device in the form of an identifier; indicating one or more selected TCI states and preset parameters to the network device in the form of a combined identifier; or indicating one or more selected TCI states and preset parameters to the network device via a MAC CE. The preset parameter indicates that multiple reference signals use the same downlink spatial filter. Some bits in the bitmap correspond one-to-one to TCI states, and each bit in the bitmap indicates whether the corresponding TCI state is selected. One identifier corresponds to one selected TCI state. One combined identifier corresponds to one or more selected TCI states. The MAC CE includes at least a TCI state area and a preset parameter area, and the number of bits in the TCI state area is related to the number of TCI states. The preset parameters implicitly indicate the beam management procedure. Reporting the beam management procedure requires multiple bits, while reporting the preset parameters only requires one bit, saving uplink resources.

[0249] To further illustrate the method in the above embodiment, an exemplary method is described in detail below:

[0250] In current technology, the beam management procedure does not have explicit indications, but is implicitly indicated in some way. For example, downlink beam management is implicitly indicated using the repetition parameter in the CSI-RS resource set in the RRC configuration and the TCI state in the CSI-RS resource. Repetition indicates that the parameter indicates that the CSI-RS resources in the resource set all use the same downlink spatial domain filter. In particular, if the repetition parameter is set to off and the TCI states of the CSI-RS resources are different, P-1 is implicitly indicated; if the repetition parameter is set to on and the TCI states of the CSI-RS resources are the same, P-2 is implicitly indicated; if the repetition parameter is set to on (the TCI states of the CSI-RS resources must be the same in this case), P-3 is implicitly indicated.

[0251] Method 1: The UE reports one or more selected TCI states or spatial relationships, as well as the repetition parameter setting, in a bitmap format on the PUCCH or PUSCH. One bit in the bitmap indicates whether the TCI state or spatial relationship is selected, while another bit indicates whether the repetition parameter is set to on or off, as shown in Figure 30.

[0252] For the combined TCI status in the unified TCI framework, a bit is required in the bitmap to indicate downlink or uplink.

[0253] Method 2: The UE reports one or more selected TCI state IDs or spatial relationship IDs, as well as the repetition parameter settings, on the PUCCH or PUSCH. The number of bits for the TCI state or spatial relationship ID and beam management procedure ID is consistent with the previous discussion, as shown in Table 34.

[0254] Table 34

[0255] The area of ​​TCI status or spatial relationship can also be reported in the form of combined ID, as shown in Table 35.

[0256] Table 35

[0257] For the combined TCI status in the unified TCI framework, a bit is required in the bitmap to indicate downlink or uplink.

[0258] Method 3: The UE reports one or more selected spatial relationships and one or more beam management procedures in the form of a MAC CE on the PUSCH. The MAC CE contains at least one of the following areas: cell ID, BWP ID, TCI status or spatial relationship information, and repetition parameter setting information. The number of bits indicating the TCI status or spatial relationship information area in the MAC CE is consistent with the previous discussion. The number of bits indicating the repetition parameter setting information is 1. For the combined TCI status in the unified TCI framework, a bit is also required in the bitmap to indicate downlink or uplink.

[0259] In particular, if there are multiple TCI states or spatial relationships reported, the repetition parameter is set to off, indicating that the UE is interested in the base station executing P-1 for the beams corresponding to these TCI states or spatial relationships; if there is only one TCI state or spatial relationship reported, the repetition parameter is set to off, indicating that the UE wants the base station to execute P-2 for the beam corresponding to this TCI state or spatial relationship; if there is only one TCI state or spatial relationship reported, the repetition parameter is set to on, indicating that the UE wants the base station to execute P-3 for the beam corresponding to this TCI state or spatial relationship.

[0260] In some embodiments, the configuration information includes a CSI reporting configuration list and a time offset list, the CSI reporting configuration list includes one or more CSI reporting configurations, the time offset list includes one or more time offsets, and the beam-related information includes beam indication information and time offset information, which is indicated in at least one of the following ways: indicating one or more selected CSI reporting configurations and time offsets to the network device in the form of a bitmap; indicating one or more selected CSI reporting configurations and time offsets to the network device in the form of an identifier; indicating one or more selected CSI reporting configurations and time offsets to the network device in the form of a combined identifier; indicating one or more selected CSI reporting configurations and time offsets to the network device via a MAC CE. Some bits in the bitmap correspond one-to-one to CSI reporting configurations, and each of those bits in the bitmap indicates whether the corresponding CSI reporting configuration is selected. One identifier corresponds to one selected CSI reporting configuration. One combined identifier corresponds to one or more selected CSI reporting configurations. The MAC CE contains at least an area for CSI reporting configuration and an area for time offset, wherein the number of bits in the area for CSI reporting configuration is related to the number of CSI reporting configurations. Details are as follows:

[0261] Time offset is not reported independently; it must be reported simultaneously with one or more of the following: CSI reporting configuration, CSI-RS resource set, SRS resource set, TCI status, spatial relationship, beam management procedure, and repetition parameter. The following example uses reporting CSI reporting configuration and time offset as an example to illustrate how to report. If reporting CSI-RS resource set, SRS resource set, TCI status, spatial relationship, or beam management procedure, replace "CSI reporting configuration" below with "CSI-RS resource set, SRS resource set, TCI status, spatial relationship, beam management procedure," or repetition parameter.

[0262] To further illustrate the method in the above embodiment, an exemplary method is described in detail below:

[0263] RRC Configuration

[0264] The above configuration information can be configured through RRC signaling, and RRC configures a CSI reporting configuration list. The list contains a number of CSI reporting configurations, assuming N.

[0265] Furthermore, / or alternatively, the RRC configuration specifies the number of CSI reporting configurations that can be reported, assuming M. When reporting in bitmap format, M may not be configured. When reporting in other formats, if M is not configured, it defaults to 1.

[0266] RRC configures a time offset list, which contains several time offsets in units of symbols or time slots. Assume there are N' time offsets.

[0267] UE reports

[0268] Method 1: The UE reports the selected M CSI reporting configurations and 1 time offset in the form of a bitmap on PUCCH or PUSCH. A part (N) of the bits in the bitmap indicates the selected CSI reporting configuration, and the other part ( The 1) bit indicates the time offset, as shown in Figure 31.

[0269] Method 2: The UE reports the selected N CSI reporting configuration IDs and 1 time offset on the PUCCH or PUSCH, as shown in Table 36.

[0270] Table 36

[0271] Method 3: The UE reports a CSI reporting configuration combination ID and a time offset on the PUCCH or PUSCH. Each combination ID corresponds to the selected M CSI reporting configurations, as shown in Table 2. The number of bits of the reported combination ID is equal to in Indicates the number of combinations of selecting M from N. The number of bits of the time offset is equal to

[0272] Method 4: The UE reports the selected N CSI reporting configurations and one time offset using a MAC CE on the PUSCH. The MAC CE contains at least one of the following fields: cell ID, BWP ID, CSI reporting configuration information, and time offset information. Figure 32 shows three MAC CE designs. The number of bits in the MAC CE indicating the CSI reporting configuration information field is consistent with the description above.

[0273] In some embodiments, beam-related information is sent to a network device via uplink control information (UCI). The UCI bit sequence includes at least one of the following: a beam-related information bit, a hybrid automatic repeat request (HARQ) bit, a scheduling request (SR) bit, and a CSI bit. When no CSI report has two parts, the two parts include a first part and a second part. There is only one UCI bit sequence. The mapping order of the beam-related information bits in the UCI bit sequence satisfies one of the following rules: the beam-related information bit is after the SR bit and before the CSI bit; and the beam-related information bit is after the CSI bit. When at least one CSI report has two parts, the UCI bit sequence includes a first UCI bit sequence and a second UCI bit sequence, and the mapping order of the beam-related information bits in the UCI bit sequence satisfies one of the following rules: the beam-related information bits are located in the first UCI bit sequence and after the SR bit; the beam-related information bits are located in the first UCI bit sequence and after the first part of the CSI bits; the beam-related information bits are located in the second UCI bit sequence and before the second part of the CSI bits; and the beam-related information bits are located in the second UCI bit sequence and after the second part of the CSI bits. Details are as follows:

[0274] In the prior art, when UCI is transmitted on the PUCCH, the UCI bit sequence is mapped in the following order: HARQ bits → SR bits → CSI bits. If no CSI report has two parts, there will be only one UCI bit sequence. If at least one CSI report has two parts, there will be two UCI bit sequences.

[0275] When beam-related information is transmitted on the PUCCH, it can be considered a new type of UCI, named BRI, in addition to HARQ, SR, and CSI. Therefore, the UCI bit sequence transmitted on the PUCCH contains at least one of the following: HARQ bits, SR bits, CSI bits, and BRI bits. Therefore, the position of the BRI bits mapped into the UCI bit sequence needs to be defined.

[0276] Example 1: No CSI report has two parts.

[0277] Method 1: The UCI bit sequence is in the following order: HARQ bit → SR bit → BRI bit → CSI bit. That is, the BRI bit comes after the SR bit and before the CSI bit. This method allows the base station to obtain the BRI faster and perform beam management more quickly.

[0278] Method 2: The UCI bit sequence is in the following order: HARQ bit → SR bit → CSI bit → BRI bit, with the BRI bit following the CSI bit. This method allows the base station to obtain CSI more quickly and determine downlink precoding more quickly.

[0279] Example 2: At least one CSI report has two parts, and the UCI bit sequence includes a first UCI bit sequence and a second UCI bit sequence.

[0280] Method 1: The order of the first UCI bit sequence is: HARQ bits → SR bits → BRI bits → CSI-part1 bits. That is, the BRI bits are in the first UCI sequence, after the SR bits and before the CSI-part1 bits. The order of the second UCI bit sequence is: CSI-part2 bits. This method allows the base station to obtain BRI faster and perform beam management more quickly.

[0281] Method 2: The order of the first UCI bit sequence is: HARQ bits → SR bits → CSI-part1 bits → BRI bits. That is, the BRI bits are in the first UCI sequence, following the CSI-part1 bits. The order of the second UCI bit sequence is: CSI-part2 bits. This method allows the base station to obtain CSI-part1 faster and demodulate CSI-part2 more quickly.

[0282] Method 3: The order of the first UCI bit sequence is: HARQ bits → SR bits → CSI-part 1 bits. The order of the second UCI bit sequence is: BRI bits → CSI-part 2 bits. That is, the BRI bits are in the second UCI sequence and before the CSI-part 2 bits. This method can improve the demodulation performance of the first UCI bit sequence.

[0283] Method 4: The order of the first UCI bit sequence is: HARQ bits → SR bits → CSI-part 1 bits. The order of the second UCI bit sequence is: CSI-part 2 bits → BRI bits. That is, the BRI bits are in the second UCI sequence and after the CSI-part 2 bits. This method can improve the demodulation performance of the first UCI bit sequence.

[0284] In addition, in the prior art, when UCI is transmitted on the PUCCH, during rate matching, the UCI bit sequence length is calculated as shown in Table 37.

[0285] Table 37

[0286] Among them E UCI Indicates the length of the UCI bit sequence, E totIndicates the length of the bit sequence after rate matching, O ACK Indicates the number of HARQ bits, O SR Indicates the number of bits of SR, O CSI-part1 Indicates the number of bits in the first part of CSI, Indicates the bit rate, Q m represents the modulation order, and L represents the number of CRC check bits.

[0287] After the new UCI type BRI is added, when UCI is transmitted on the PUCCH, the calculation of the UCI bit sequence length needs to include the impact of the BRI bit during rate matching.

[0288] Example 1: No CSI report has two parts. The UCI bit sequence length is calculated as shown in Table 38.

[0289] Table 38

[0290] Example 2: At least one CSI report has two parts. The UCI bit sequence length is calculated as shown in Table 39 and Table 40.

[0291] Method 1: BRI is in the first UCI bit sequence. The calculation of the UCI bit sequence length is shown in Table 39.

[0292] Table 39

[0293] Method 2: In the second UCI bit sequence of BRI, the UCI bit sequence length is calculated as shown in Table 40.

[0294] Table 40

[0295] O BPI Indicates the number of bits of BRI. These tables only show the part containing BRI, and the rest are the same as the prior art.

[0296] In some embodiments, when the PUCCH resource carrying SR overlaps with the PUCCH resource carrying beam-related information, the SR is multiplexed onto the PUCCH resource carrying beam-related information. In other embodiments, when the PUCCH resource carrying beam-related information overlaps with the PUCCH resource carrying at least one of HARQ, SR, and CSI, a PUCCH resource is selected from the overlapping PUCCH resources to transmit at least one of the beam-related information, HARQ, SR, and CSI. Details are as follows:

[0297] Multiplexing of BRI PUCCH and SR PUCCH

[0298] The number of bits in BRI is 0BRI (usually greater than 2 bits) and is carried by PUCCH format 2 / 3 / 4. SR is carried by PUCCH format 1. When the PUCCH resources carrying K SRs overlap with the PUCCH resources carrying BRI, SR will be multiplexed onto the PUCCH resources for beam prediction information. The total number of bits of these two types of UCI is

[0299] Multiplexing of BRI with HARQ (if any), SR (if any), and CSI (if any)

[0300] When different PUCCH resources carrying BRI, HARQ (if any), SR (if any), and CSI (if any) overlap, a set of these PUCCH resources is first obtained according to resource selection rules in the prior art. Then, a PUCCH for transmission is selected from the set of PUCCH resources based on the sum of the number of bits of BRI, HARQ (if any), SR (if any), CSI (if any), and CRC. For example, when different PUCCH resources carrying BRI and SR overlap, SR is multiplexed onto the PUCCH resource carrying BRI.

[0301] In some embodiments, the coded modulation symbols are calculated or allocated according to one of the following orders: HARQ, beam-related information, the first part of CSI, the second part of CSI; HARQ, the first part of CSI, beam-related information, the second part of CSI; and HARQ, the first part of CSI, the second part of CSI, beam-related information. Detailed description is as follows:

[0302] In the prior art, when UCI is transmitted on the PUSCH, during rate matching, the order of calculation / allocation of coded modulation symbols is: HARQ→CSI-part1→CSI-part2.

[0303] The number of HARQ coded modulation symbols:

[0304] Among them O ACK Indicates the number of HARQ bits, L ACK Indicates the number of bits of HARQ CRC check, K r Indicates the size of the rth code block of PUSCH, C UL-SCH Indicates the number of PUSCH code blocks, Indicates the bandwidth of PUSCH (the unit is the number of subcarriers), Indicates the number of REs used to transmit UCI on the lth symbol, Indicates the total number of PUSCH symbols (including DMRS symbols), l0 indicates the first symbol after the first DMRS symbol of PUSCH, and α is configured by high-level parameters. Configured by high-level parameters or dynamically indicated.

[0305] Number of coded modulation symbols for CSI-part1:

[0306] Among them O CSI-1 Indicates the number of bits of CSI-part1, L CSI-1 Indicates the number of bits for CRC check of CSI-part1, K r Indicates the size of the rth code block of PUSCH, C UL-SCH Indicates the number of PUSCH code blocks, Indicates the bandwidth of PUSCH (the unit is the number of subcarriers), Indicates the number of REs used to transmit UCI on the lth symbol, Indicates the total number of PUSCH symbols (including DMRS symbols), α is configured by high-level parameters, Configured by high-level parameters or dynamically indicated. If there is no CG-UCI, Q'ACK / CG-UCI = Q' ACK .

[0307] Number of coded modulation symbols for CSI-part2:

[0308] Among them O CSI-2 Indicates the number of bits of CSI-part2, L CSI-2 Indicates the number of bits for the CRC check of CSI-part2, K r Indicates the size of the rth code block of PUSCH, C UL-SCH Indicates the number of PUSCH code blocks, Indicates the bandwidth of PUSCH (the unit is the number of subcarriers), Indicates the number of REs used to transmit UCI on the lth symbol, Indicates the total number of PUSCH symbols (including DMRS symbols), α is configured by high-level parameters, Configured by high-level parameters or dynamically indicated. If there is no CG-UCI, Q'ACK / CG-UCI = Q' ACK .

[0309] After the new UCI type BRI is added, when UCI is transmitted on PUCSH, the calculation / allocation of the number of coded modulation symbols needs to take BRI bits into account during rate matching.

[0310] Method 1:

[0311] The calculation / allocation order of coded modulation symbols is: HARQ → BRI → CSI-part1 → CSI-part2.

[0312] The number of HARQ coded modulation symbols remains unchanged.

[0313] Number of BRI coded modulation symbols:

[0314] Among them O BPI Indicates the number of bits of BRI, L BRI Indicates the number of bits used in the BRI CRC checksum.

[0315] Number of coded modulation symbols for CSI-part1:

[0316] Number of coded modulation symbols for CSI-part2:

[0317] Method 2:

[0318] The calculation / allocation order of coded modulation symbols is: HARQ → CSI-part1 → BRI → CSI-part2.

[0319] The number of coded modulation symbols for HARQ and CSI-part1 remains unchanged.

[0320] Number of BRI coded modulation symbols:

[0321] Among them O BPI Indicates the number of bits of BRI, L BRI Indicates the number of bits used in the BRI CRC checksum.

[0322] Number of coded modulation symbols for CSI-part2:

[0323] Method 3:

[0324] The calculation / allocation order of coded modulation symbols is: HARQ → CSI-part1 → CSI-part2 → BRI.

[0325] The number of coded modulation symbols for HARQ, CSI-part1, and CSI-part2 remains unchanged.

[0326] Number of BRI coded modulation symbols:

[0327] Among them O BPI Indicates the number of bits of BRI, L BRIIndicates the number of bits used in the BRI CRC checksum.

[0328] In some embodiments, resource mapping is performed according to one of the following rules: starting from the first non-DMRS symbol of the PUSCH, mapping the bits of beam-related information, the first part of the CSI bits, and the second part of the CSI bits in sequence; starting from the first non-DMRS symbol of the PUSCH, mapping the first part of the CSI bits, the bits of beam-related information, and the second part of the CSI bits in sequence; and starting from the first non-DMRS symbol of the PUSCH, mapping the first part of the CSI bits, the second part of the CSI bits, and the bits of beam-related information in sequence. Details are as follows:

[0329] In the prior art, when UCI is transmitted on the PUSCH, during resource mapping, the HARQ bits are mapped to part of the resources of the first symbol after the first DMRS of the PUSCH; the CSI-part1 bits are mapped starting from the first non-DMRS symbol of the PUSCH; after the CSI-part1 bits are mapped, the CSI-part2 bits are mapped next; the mapping of the CSI-part1 and CSI-part2 bits skips the DMRS symbols.

[0330] After the new UCI type BRI is added, resource mapping needs to take BRI into account when UCI is transmitted on PUCSH.

[0331] Method 1: HARQ bits are mapped to the partial resources of the first symbol after the first DMRS symbol of the PUSCH. BRI bits are mapped starting from the first non-DMRS symbol of the PUSCH. After the BRI bits are mapped, CSI-part1 bits are mapped next to the BRI resources. After the CSI-part1 bits are mapped, CSI-part2 bits are mapped next. The mapping of BRI, CSI-part1, and CSI-part2 bits skips DMRS symbols. This method allows the base station to obtain BRI faster and perform beam management more quickly.

[0332] Method 2: HARQ bits are mapped to the partial resources of the first symbol after the first DMRS symbol of the PUSCH; CSI-part1 bits are mapped starting from the first non-DMRS symbol of the PUSCH; after the CSI-part1 bits are mapped, the BRI bits are mapped next; after the BRI bits are mapped, the CSI-part2 bits are mapped next to the BRI resources; the mapping of BRI, CSI-part1, and CSI-part2 bits skips DMRS symbols. This method allows the base station to obtain CSI-part1 faster and prepare for downlink precoding more quickly.

[0333] Method 3: HARQ bits are mapped to the first symbol after the first DMRS symbol of the PUSCH. CSI-part1 bits are mapped starting from the first non-DMRS symbol of the PUSCH. After the CSI-part1 bits are mapped, the CSI-part2 bits are mapped next. After the CSI-part2 bits are mapped, the BRI bits are mapped next.
