[0121] In some embodiments, the core network device can be one device including multiple network elements, etc., or can be multiple devices or device groups, each including all or part of multiple network elements. The network element can be virtual or physical. The core network includes, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

[0122] In some embodiments, the terminal starts the fast beam sweeping, and the measurement period of the reference signal can be shortened. Meanwhile, activating multiple antenna panels will increase the power consumption of the terminal. While improving the availability of fast beam sweeping, the power consumption of the terminal can also be considered. Therefore, the starting point and the ending point of the fast beam sweeping can be determined. The starting point of the fast beam sweeping can refer to the time point at which the terminal starts the fast beam sweeping. The ending point of the fast beam sweeping can refer to the time point at which the terminal stops the fast beam sweeping.

[0126] In some embodiments, the first signaling can be used to start the fast beam sweeping.

[0127] In some embodiments, the fast beam sweeping refers to a process in which the terminal 101 activates multiple antenna panels simultaneously to perform beam sweeping and thus perform reference signal measurement. The reference signal can include but is not limited to a Channel State Information Reference Signal (CSI-RS).

[0128] In some embodiments, the terminal 101 receives the first signaling.

[0129] In some embodiments, the name of the first signaling is not limited, and the first signaling can be interchangeable with a first control signaling, fast beam sweeping start signaling, etc.

[0134] In one example, considering that the protocol modification is relatively complex, the network device 102 can reuse an existing information element (IE) in the first RRC signaling to instruct the terminal 101 to start the fast beam sweeping.

[0135] For example, the network device 102 can reuse the first IE to instruct the terminal 101 to start the fast beam sweeping. The first IE can be any existing IE in the first RRC signaling, which is not limited in the present disclosure.

[0136] For example, the first IE can be an IE for configuring group-based beam reporting (GBBR) for the terminal 101.

[0137] For example, if the network device 102 enables the GBBR through the first IE, or configures the GBBR for the terminal 101, the terminal 101 needs to report multiple best beams in a measurement report of a reference signal, for example, including a pair of two best beams. The best beam here can refer to the best receiving beam determined by the terminal through the measurement result of the reference signal. At this time, the terminal 101 can determine that the fast beam sweeping needs to be started based on the first IE in the first RRC signaling.

[0138] For example, the network device 102 configures the GBBR for the terminal 101 through the first IE as follows:

[0139] The above is only an example, and the specific implementation of starting the fast beam sweeping by reusing the existing first IE is not limited in the present disclosure.

[0140] In one example, considering that reusing the existing IE can cause the terminal 101 to behave uncertainly, the network device 102 can add a new IE in the first RRC signaling, for example, add a second IE, which is used to instruct the terminal 101 to start the fast beam sweeping.

[0141] For example, the second IE is configured as “enabled” (or activated), which can be used to instruct to start the fast beam sweeping, and the specific configuration is as follows:

[0142] CSI-ReportConfig::= SEQUENCE{

[0143] Fastbeamsweeping ENUMERATED{enabled,disabled}

[0144] },

[0145] The above is only an example description, and the present disclosure does not limit the specific implementation manner of enabling the fast beam sweeping by the second IE.

[0146] In one example, the first command can be used to activate a first number of Transmission Control Indicator (TCI) states. Wherein the first number is greater than 1, and exemplarily, the first number can be 2, 3, …, etc. positive integer.

[0147] Wherein, the network device 102 can send a TCI to the terminal 101, which is used to indicate a Quasi Co-Location (QCL) relationship between antenna ports of the downlink. Different TCI states can correspond to different QCL relationships between antenna ports of the downlink of the terminal. Wherein, the TCI state can also be further used to control beam switching.

[0148] Exemplarily, the first command can be a first Media Access Control Element (MAC CE).

[0149] Exemplarily, the first command can be a first Downlink Control Information (DCI).

[0150] Exemplarily, the first command can be used for single Downlink Control Information (sDCI).

[0151] It can be understood that at this time, the first command can be sent to one of the multiple Transmit Receive Points (TRPs).

[0152] In the embodiments of the present disclosure, each of the multiple TRPs can correspond to one antenna panel of the terminal 101.

[0153] For example, there are 2 antenna panels on the terminal 101, and the same command can be exchanged between the 2 antenna panels. When the first command can be sent to one of the antenna panels, assuming that it is sent to antenna panel #1, the antenna panel #1 can determine the TCI state corresponding to itself based on the first command, and another antenna panel, for example, antenna panel #2, can also determine the TCI state corresponding to itself.

[0154] Exemplarily, the first command can be used for multi-Downlink Control Information (mDCI).

[0155] It can be understood that the first command can be sent to each of the plurality of TRPs at this time.

[0156] For example, there are a total of 2 antenna panels on the terminal 101, the first command is sent to the antenna panel #1 and the antenna panel #2, and the two antenna panels respectively determine their corresponding TCI states based on the first command.

[0157] Exemplarily, the first command can be a multi-TCI state switching command. That is, the first command can be used to instruct each TRP to perform TCI state switching.

[0158] Exemplarily, the first command can be a multi-TCI state list switching command. That is, the first command can be used to instruct each TRP to perform TCI state switching in the TCI state list.

[0159] Exemplarily, the first command can be a first MAC CE, and the first MAC CE is a multi-TCI state switching command for sDCI.

[0160] Exemplarily, the first command can be a first MAC CE, and the first MAC CE is a multi-TCI state switching command for mDCI.

[0161] Exemplarily, the first command can be a first MAC CE, and the first MAC CE is a multi-TCI state list switching command for sDCI.

[0162] Exemplarily, the first command can be a first MAC CE, and the first MAC CE is a multi-TCI state list switching command for mDCI.

[0163] Exemplarily, the first command can be a first DCI, and the first DCI is a multi-TCI state switching command for sDCI.

[0164] Exemplarily, the first command can be a first DCI, and the first DCI is a multi-TCI state switching command for mDCI.

[0165] Exemplarily, the first command can be a first DCI, and the first DCI is a multi-TCI state list switching command for sDCI.

[0166] Exemplarily, the first command can be a first DCI, and the first DCI is a multi-TCI state list switching command for mDCI.

[0167] The above is only an exemplary description, and the specific content of the first command is not limited by the disclosure.

[0168] Step S2102, the terminal 101 activates a first number of antenna panels.

[0169] In some embodiments, the terminal 101 determines, based on the first command, that the start point of the fast beam sweeping is reached, i.e., the fast beam sweeping needs to be started. At this time, the terminal 101 can activate the plurality of antenna panels.

[0170] The first number can be a positive integer greater than 1.

[0171] In step S2103, the terminal 101 determines the first measurement result of the reference signal.

[0172] In some embodiments, the terminal 101 can perform the fast beam sweeping through the first number of antenna panels in the activated state to obtain the first measurement result of the reference signal.

[0173] In some embodiments, the terminal 101 can send the first measurement result to the network device 102 through a measurement report. For example, the terminal 101 can send the indexes of the two best beams, the Lay1-Reference Signal Receiving Power (L1-RSRP) corresponding to each best beam, etc. to the network device 102 through a GBBR report. The layer 1 can be a physical layer.

[0180] The communication method related to the embodiments of the present disclosure can include at least one of steps S2101-S2103. For example, step S2101 can be implemented as an independent embodiment, step S2102 can be implemented as an independent embodiment, steps S2101+S2102 can be implemented as an independent embodiment, steps S2102+S2103 can be implemented as an independent embodiment, steps S2101+S2102+S2103 can be implemented as an independent embodiment, but the present disclosure is not limited thereto.

[0181] In some embodiments, steps S2102 and S2103 are optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0182] In some embodiments, step S2101 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0183] In some embodiments, the execution order of steps S2101-S2103 is not limited.

[0184] In the above embodiments, the network device can trigger the terminal to start the fast beam sweeping, improve the reliability of the terminal to perform the fast beam sweeping, improve the measurement efficiency of the reference signal, and take into account the terminal power consumption, and has high availability.

[0185] FIG. 2B is an interaction diagram of a beam sweeping method according to an embodiment of the present disclosure. As shown in FIG. 2B, the embodiments of the present disclosure relate to a beam sweeping method, and the above method includes:

[0186] In step S2201, the network device 102 sends second signaling to the terminal 101.

[0187] In some embodiments, the second signaling can be used to close the fast beam sweeping.

[0188] In some embodiments, the network device 102 can determine to send the second signaling to the terminal 101 when it is necessary to close the fast beam sweeping based on a predefined rule and / or its own implementation. For example, the network device 102 determines that the duration of the terminal 101 starting the fast beam sweeping reaches a preset duration, and for another example, the network device 102 determines that the terminal 101 is in a low-power mode based on the residual power indication information reported by the terminal 101 and / or the power indication information reported by the terminal 101, and at this time, the network device 102 determines that it is necessary to close the fast beam sweeping.

[0189] In some embodiments, the terminal 101 receives the second signaling.

[0190] In some embodiments, the second signaling is not limited in name, and can be interchangeable with second control signaling, fast beam sweeping off signaling, and the like.

[0191] In some embodiments, the second signaling can include, but is not limited to, at least one of the following:

[0192] Second RRC signaling;

[0193] Second command.

[0194] In one example, the second RRC signaling can include, but is not limited to, any one of the following: RRCReconfiguration signaling; RRCSetup signaling; and the like.

[0195] In one example, considering that protocol modification is relatively complex, the network device 102 can reuse an existing IE in the first RRC signaling to instruct the terminal 101 to turn off fast beam sweeping, thereby avoiding wasting terminal 101 power consumption.

[0196] Exemplarily, the network device 102 can reuse the first IE to instruct the terminal 101 to turn off fast beam sweeping. The first IE can be any one of the existing IEs in the first RRC signaling, which is not limited in the present disclosure.

[0197] Exemplarily, the first IE can be an IE for disabling the GBBR configured for the terminal 101.

[0198] Exemplarily, if the network device 102 disables the GBBR through the first IE, or deactivates or disables the GBBR configured for the terminal 101, the terminal 101 can only report 1 best beam in a measurement report of a reference signal. The best beam here can refer to the best receiving beam determined by the terminal through the measurement result of the reference signal. At this time, the terminal 101 can determine that fast beam sweeping needs to be turned off based on the first IE in the second RRC signaling.

[0199] Exemplary description of disabling the GBBR configured for the terminal 101 through the first IE is as follows:

[0200] The above is only an exemplary description, and the present disclosure is not limited in specific implementation manners of turning off fast beam sweeping by reusing the existing first IE.

[0201] In one example, considering that reusing the existing IE can cause uncertain behavior of the terminal 101, the network device 102 can add a new IE in the second RRC signaling, for example, add a second IE for instructing the terminal 101 to turn off fast beam sweeping.

[0202] When the second IE is configured to be "disabled" (or "inactive"), it can be used to indicate that fast beam scanning is turned off. The specific configuration method is as follows:

[0203] CSI-ReportConfig::= SEQUENCE{

[0204] Fastbeamsweeping ENUMERATED{enabled,disabled}

[0205] },

[0206] The above is merely an illustrative example, and this disclosure does not limit the specific implementation method of disabling fast beam scanning through the second IE.

[0207] In one example, the second command can be used to activate a TCI state.

[0208] For example, the second command can be a second MAC CE.

[0209] For example, the second command can be a second DCI.

[0210] For example, the second command can be used for sDCI. It is understood that the second command can be sent to one of multiple TRPs at this time.

[0211] In this embodiment of the disclosure, each of the plurality of TRPs may correspond to an antenna panel of terminal 101.

[0212] For example, the second command can be used for mDCI. It is understood that the second command can be sent to each of the multiple TRPs in this case.

[0213] For example, the second command can be a TCI activation command, which includes only one TCI state, or only configures one TCI state corresponding to one TRP.

[0214] For example, the second command can be a second MAC CE, which is a TCI activation command for sDCI.

[0215] For example, the second command can be a second MAC CE, which is a TCI activation command for mDCI.

[0216] For example, the second command can be a second DCI, which is a TCI activation command for sDCI.

[0217] Exemplarily, the second command can be a second DCI, and the second DCI is a TCI activation command for the mDCI.

[0218] The above is only an exemplary description, and the disclosure does not limit the specific content of the second command.

[0219] In step S2202, the terminal 101 deactivates the second number of antenna panels.

[0220] In some embodiments, the terminal 101 has previously started the fast beam sweeping.

[0221] In some embodiments, the terminal 101 determines, based on the second command, that the terminal has reached the end of the fast beam sweeping, i.e., the fast beam sweeping needs to be turned off. At this time, the terminal 101 can deactivate at least one antenna panel, so that the number of antenna panels in the activated state is 1.

[0222] The difference between the first number and the second number is 1.

[0223] In step S2203, the terminal 101 determines a second measurement result of the reference signal.

[0224] In some embodiments, the terminal 101 can perform the beam sweeping through the one antenna panel in the activated state, thereby obtaining the second measurement result of the reference signal.

[0225] In some embodiments, the terminal 101 can send the second measurement result to the network device 102 through a measurement report. Exemplarily, the terminal 101 can send the index of the best beam, the L1-RSRP corresponding to the best beam, etc. to the network device 102 through a GBBR report.

[0226] The communication method related to the embodiments of the disclosure can include at least one of steps S2201-S2203. For example, step S2201 can be implemented as an independent embodiment, step S2202 can be implemented as an independent embodiment, steps S2201+S2202 can be implemented as an independent embodiment, steps S2202+S2203 can be implemented as an independent embodiment, and steps S2201-S2203 can be implemented as an independent embodiment, but not limited thereto.

[0227] In some embodiments, steps S2202 and S2203 are optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0228] In some embodiments, step S2201 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0229] In some embodiments, the execution sequence of steps S2201 to S2203 is not limited.

[0230] In the above embodiments, after the terminal starts the fast beam sweeping, the network device can trigger the fast beam sweeping to be closed, thereby improving the reliability of the fast beam sweeping of the terminal, improving the measurement efficiency of the reference signal, and taking into account the terminal power consumption and high availability.

[0231] FIG. 2C is an interaction diagram of a beam sweeping method according to an embodiment of the present disclosure. As shown in FIG. 2C, the present disclosure relates to a beam sweeping method, and the method includes:

[0232] In step S2301, the terminal 101 determines that the fast beam sweeping needs to be closed.

[0233] In some embodiments, if the terminal 101 is in a first state, the terminal 101 can determine that the fast beam sweeping needs to be closed at this time.

[0234] In some embodiments, the first state can refer to a low-power state.

[0235] In some embodiments, if the power value of the terminal 101 is lower than a first value and / or the power value is lower than a second value, the terminal 101 can determine that it is in the first state, and at this time, in order to save the power consumption of the terminal 101, the terminal 101 can determine that the fast beam sweeping needs to be closed.

[0236] In step S2302, the terminal 101 sends third signaling to the network device 102.

[0237] In some embodiments, the third signaling can be used to close the fast beam sweeping.

[0238] In some embodiments, the network device 102 receives the third signaling.

[0239] In some embodiments, based on the third signaling, the network device 102 determines that the terminal 101 has closed the fast beam sweeping.

[0240] In some embodiments, the third signaling can include, but is not limited to, at least one of the following:

[0241] Third RRC signaling;

[0242] Terminal assistance information (UE Assistance Information).

[0243] In some embodiments, the third signaling can also be other signaling, such as MAC CE, uplink control information (UCI), etc., which are not limited by the present disclosure.

[0244] In some embodiments, the third signaling is a third RRC signaling, and the third RRC signaling can include a GBBR. Accordingly, the terminal 101 can indicate the disabling of the fast beam sweeping in the following manners:

[0245] Manner 1: including one beam index in the GBBR.

[0246] For example, the GBBR includes multiple beam indexes, such as the indexes of the two best beams determined by the terminal 101. In the embodiments of the present disclosure, in order to inform the network device 102 that the terminal 101 has disabled the fast beam sweeping, only one beam index can be included in the GBBR.

[0247] Manner 2: including multiple beam indexes in the GBBR, and a layer 1 reference signal received power (L1-RSRP) value corresponding to each beam index; wherein the second number of L1-RSRP values is empty.

[0248] For example, the GBBR still includes multiple beam indexes, and in order to inform the network device 102 that the terminal 101 has disabled the fast beam sweeping, the second number of L1-RSRP values can be set to empty. Since the difference between the first number and the second number is 1, the multiple beam indexes in the GBBR and the one non-empty L1-RSRP value, and the other L1-RSRP values are empty (NULL).

[0249] For example, the first number is 2, and the GBBR includes a beam index #1 and a beam index #2, wherein the L1-RSRP value corresponding to the beam index #1 is L1-RSRP #1, and the L1-RSRP value corresponding to the beam index #2 is NULL.

[0250] In some embodiments, the third signaling is terminal assistance information, and the terminal assistance information can include a third IE indicating that the number of beams of the terminal 101 is 1.

[0251] The third IE can be an existing IE in the terminal assistance information, such as multiRx-PreferenceFR2-r18. The terminal 101 can set the IE multiRx-PreferenceFR2-r18 to single.

[0252] The third IE can be a newly added IE in the terminal assistance information, i.e., the third IE is used to indicate the disabling of the fast beam sweeping or the number of beams of the terminal 101 is 1.

[0253] The above is only an example, and the present disclosure does not limit the scheme for the terminal to indicate the disabling of the fast beam sweeping.

[0254] At step S2303, the terminal 101 deactivates the second number of antenna panels.

[0255] In some embodiments, the implementation of step S2303 is similar to the aforementioned step S2202, and details are not repeated here.

[0256] At step S2304, the terminal 101 determines the second measurement result of the reference signal.

[0257] In some embodiments, the implementation of step S2304 is similar to the aforementioned step S2203, and details are not repeated here.

[0258] The communication method related to the embodiments of the present disclosure can include at least one of steps S2301-S2304. For example, step S2301 can be implemented as an independent embodiment, step S2302 can be implemented as an independent embodiment, steps S2301+S2302 can be implemented as an independent embodiment, steps S2303+S2304 can be implemented as an independent embodiment, steps S2301-S2304 can be implemented as an independent embodiment, but not limited to this.

[0259] In some embodiments, steps S2302, S2303, S2304 are optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0260] In some embodiments, step S2301 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0261] In some embodiments, the execution order of steps S2301-S2304 is not limited.

[0262] In the above embodiments, after the terminal starts the fast beam sweeping, the terminal can trigger the fast beam sweeping to be closed, which improves the reliability of the fast beam sweeping of the terminal, improves the measurement efficiency of the reference signal, and takes into account the terminal power consumption, and has high availability.

[0263] In some embodiments, the scheme of FIG. 2A can be combined with the scheme of FIG. 2B, i.e., the network device 102 can trigger the fast beam sweeping to be started, and the network device 102 can trigger the fast beam sweeping to be closed.

[0335] In the above embodiments, the network device can determine that the terminal has closed the fast beam sweeping based on the third signaling, improve the measurement efficiency of the reference signal, take into account the terminal power consumption, and have high availability.

[0336] The above process is further illustrated as follows.

[0337] In the embodiments of the present disclosure, considering terminal energy saving, it is necessary to define the starting point and end point of fast beam sweeping with multiple panels.

[0338] I. Starting point of fast beam sweeping

[0339] Option 1: The network device enables group-based beam reporting, or the terminal is configured with GBBR reporting.

[0340] Option 2: Use a dual-TCI state switching command to activate the fast beam sweeping of the terminal.

[0341] The dual-TCI state switching command can include the following candidate commands:

[0342] 1. MAC CE-based dual-TCI state switching command for sDCI, or

[0343] 2. MAC CE-based dual-TCI state switching command for mDCI, or

[0344] 3. MAC CE-based dual-TCI state list switching command for sDCI, or

[0345] 4. MAC CE-based dual-TCI state list switching command for mDCI, or

[0346] 5. DCI-based dual-TCI state switching command for sDCI, or

[0347] 6. DCI-based dual-TCI state switching command for mDCI.

[0348] Option 3: Design a new dedicated IE to start fast beam sweeping in the CSI report configuration.

[0349] CSI-ReportConfig::= SEQUENCE{

[0350] Fastbeamsweeping ENUMERATED{enabled,disabled}

[0351] },

[0352] The reasons for designing option 3 are as follows:

[0353] Fast beam sweeping can be applied to the case of multi-transmission reception point (mTRP), in which there are two schemes as follows:

[0354] - Time-Division Multiplexing (TDM) is configured with L1-RSRP measurement for non-GBBR.

[0355] - Space-Division Multiplexing (SDM) is configured with L1-RSRP measurement for GBBR.

[0356] TDM means that the terminal will receive two signals from two TRPs one after another, instead of receiving them simultaneously. SDM means that the terminal will receive two signals from two TRPs simultaneously. Therefore, two types of L1-RSRP measurement will be configured.

[0357] For L1-RSRP measurement in GBBR, the terminal needs to report the best two beams in a pair in one report. Then, the two TRPs can use the two beams to transmit signals simultaneously.

[0358] For L1-RSRP measurement in non-GBBR, the terminal needs to report one best beam for each TRP in one report, and the two beams will not be paired.

[0359] The network device can configure GBBR for SDM and non-GBBR for TDM in mTRP. In the case of switching between TDM and SDM, the network device needs the terminal to provide two reports. In this case, the motivation of configuring GBBR is not for fast beam sweeping, but for SDM. However, if the IE of configuring GBBR is reused to indicate fast beam sweeping, the terminal will be forced to perform fast beam sweeping in non-GBBR, resulting in ambiguous terminal behavior. Therefore, a dedicated IE can be designed to start fast beam sweeping for non-GBBR.

[0360] II. End point of fast beam sweeping

[0361] Case 1, controlled by the network device.

[0362] Option 1, disable group-based beam reporting by the network device

[0363] In option 1, the network device can configure GBBR in sTRP for SDM, and configure non-GBBR in TDM. If the network device wants to stop the fast beam sweeping of non-GBBR, the terminal needs to disable GBBR. If GBBR is disabled, the network device can stop the fast beam sweeping of non-GBBR, and no longer report GBBR. In this case, the network device will not get the report of GBBR, which is obviously not the intention of the embodiments of the present disclosure. Therefore, in one example, the following option 2 is also proposed to design a dedicated IE for fast beam sweeping.

[0364] Option 2, design a new dedicated IE, use “disable” in CSI report configuration to start fast beam sweeping.

[0365] CSI-ReportConfig::= SEQUENCE{

[0366] Fastbeamsweeping ENUMERATED{enabled,disabled}

[0367] },

[0368] Through option 2, it can be clearly distinguished between stopping GBBR in non-GBBR or stopping fast beam sweeping.

[0369] Option 3, the dual-TCI state switching command falls back to the single-TCI state command.

[0370] For option 3, for sDCI, a MAC CE or DCI-based TCI activation command will only include one TCI state. For mDCI, only one MAC CE command from one TRP will be configured.

[0371] Case 2, controlled by the terminal.

[0372] If the terminal detects a low-power state, the terminal can send an indication to the network device to stop fast beam sweeping. There are two options:

[0373] Option 4, the terminal sends an indication in the GBBR report.

[0374] -Option 4-1, the terminal will only feed back one beam index in the GBBR report.

[0375] -Option 4-2, the terminal will feed back two beam indexes in the GBBR report, each beam index corresponds to 1 L1-RSRP. One of the 2 L1-RSRP values is set to NULL.

[0376] Option 5, the terminal sends an indication in the auxiliary information

[0377] For example, set multiRx-PreferenceFR2-r18 in UEAssistanceInformation to "single".

[0378] Embodiment 1, SSB-based L1-RSRP reporting

[0379] …

[0380] The terminal activates the multi-Rx operation when the following conditions are met:

[0381] The terminal is configured with group-based beam report (GBBR) reporting

[0382] The terminal deactivates the multi-Rx operation when the following conditions are met:

[0383] The group-based beam report (GBBR) reporting is disabled.

[0384] Embodiment 2, SSB-based L1-RSRP reporting

[0385] …

[0386] The terminal activates the multi-Rx operation when the following conditions are met:

[0387] The UE activates the multi-Rx operation through a dual-TCI state switch

[0388] The terminal deactivates the multi-Rx operation when the following conditions are met:

[0389] The dual-TCI state switch falls back to a single-TCI state.

[0390] The N value in Table 9.5.4.1-2A is 8.

[0391] The above is only an exemplary illustration, and other options provided by the above schemes can be specified in the protocol in a similar manner.
