At present, for the MPUE, a plurality of panels of the terminal may each simultaneously form a respective uplink (UL) beam. However, the network side device is not capable of determining which UL beams may be simultaneously used, which is prone to resource waste.
The following describes in detail the information transmission method provided in the embodiments of this application through some embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in
S210: The terminal reports a beam report to a network side device based on a beam measurement result, where the beam report is used to determine N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending, where N is a positive integer greater than or equal to 2. For simplicity, the following embodiments use N=2 as an example for description.
Before step S210, the method further includes:
The network side device indicates a related parameter of the beam report to the terminal, where the related parameter includes content and a format of the beam report, and the like. For example, it may be indicated that the beam report includes a reference signal resource indicator, beam link quality information, and the like, and the beam report is a non-group-based or group-based beam report.
The network side device sends a reference signal for beam measurement, where the reference signal may be a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS).
The terminal obtains the beam measurement result by measuring the reference signal, and sends the beam report to the network side device based on the beam measurement result.
The network side device determines, based on the beam report, N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending.
It should be understood that the beam information may also be referred to as identification information of a beam, spatial relation information, spatial domain transmission filter information, spatial domain reception filter information, spatial filter information, transmission configuration indicator state (TCI state) information, quasi co-location (QCL) information, a QCL parameter, or the like. Downlink beam information may usually be represented by the TCI state information or the QCL information. Uplink beam information may usually be represented by the TCI state information or the spatial relation information.
S220: The terminal receives first indication information from the network side device, where the first indication information is used to indicate the terminal to simultaneously send uplink signals by using the N pieces of beam information.
Each of the N pieces of beam information corresponds to any one of the following:
In an implementation, before beam measurement is performed, the terminal may first send at least one of the foregoing information to the network side device. For example, a group of capability value information or a group of capability value set information is included in capability information reported by the UE.
It should be understood that a panel may also be referred to as an antenna group, an antenna port group, an antenna set, an antenna port set, a beam set, a beam sub-set, an antenna array, an antenna port array, an antenna sub-array, an antenna port sub-array, a logical entity, an entity or an antenna entity, a panel entity, a timing error group (TEG), or the like.
It should be understood that an identifier of the panel may be an identifier of an antenna panel, a reference signal resource identifier, a reference signal resource set identifier, a TCI state identifier, a QCL information identifier, a spatial relationship identifier, or the like.
It should be understood that the capability value or the capability value set may include at least one of parameters such as a quantity of ports, a quantity of layers, a rank, or a coherence type of a sounding reference signal (SRS) that is supported by the terminal.
According to the technical solution in the foregoing embodiment, in this embodiment of this application, the terminal reports the beam report to the network side device based on the beam measurement result, and the network side device determines, based on the beam report, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending, and indicates the terminal to simultaneously send uplink signals by using the N pieces of beam information. Therefore, beam information of uplink signals that are capable of being simultaneously sent in a multi-panel terminal is quickly determined, and resource utilization efficiency is improved.
Based on the foregoing embodiment, the beam report may be in a variety of formats, such as using a non-group-based beam report and/or a group-based beam report.
In an implementation, the beam report may include at least one of the following:
The reference signal resource indicator includes a synchronization signal block resource indicator (SSBRI), a channel state information reference signal resource indicator (CRI), and the like, which are represented as SSBRI/CRI in the following embodiments. A reference signal of the reference signal resource indicator is a reference signal (RS) resource for beam measurement, SSBRI indicates an SSB resource for beam measurement, and CRI indicates a CSI-RS resource for beam measurement.
The first index is used to indicate first information of the terminal, where the first information is any one of the following:
The beam link quality information may include a layer 1 reference signal received power (L1-RSRP), a layer 1 signal-to-noise and interference ratio (L1-SINR), and is represented as L1-RSRP/L1-SINR in the following embodiments.
For example, a beam report 1 is shown as follows:
It can be learned that the beam report 1 includes four reference signal resource indicators: SSBRI/CRI #1, SSBRI/CRI #2, SSBRI/CRI #3, and SSBRI/CRI #4.
Pieces of beam link quality information each respectively corresponding to each reference signal resource indicator are: L1-RSRP/L1-SINR #1, L1-RSRP/L1-SINR #2, L1-RSRP/L1-SINR #3, and L1-RSRP/L1-SINR #4.
First indexes each corresponding to each reference signal resource indicator are: index #1, index #2, index #3, and index #4.
The first indexes each corresponding to each reference signal resource indicator may be the same or different.
In an implementation, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending may be determined based on reference signal resource indicators corresponding to N different first indexes. For example, in the beam report 1, if values of index #1 and index #2 are different, it is determined that the terminal may simultaneously send uplink signals based on the two pieces of beam information corresponding to SSBRI/CRI #1 and SSBRI/CRI #2. For example, an RS resource indicated by SSBRI/CRI #1 and SSBRI/CRI #2 is used as a source reference signal of an uplink channel or an uplink reference signal (RS), so that the uplink channel or the uplink RS may be scheduled by the network side device and simultaneously sent by the terminal by using multiple beams. In this case, the multiple beams used to simultaneously send the uplink signal correspond to different first indexes, and may be understood as corresponding to different terminal panels. The uplink reference signal may be an SRS or the like.
A quantity of pieces of beam link quality information corresponding to the reference signal resource indicator in the beam report may be one or more.
For example, a beam report 2 is shown as follows:
It can be learned that, in the beam report 2, SSBRI/CRI #1 and SSBRI/CRI #2 are respectively corresponding to two pieces of beam link quality information, and reference signal resource indicators SSBRI/CRI #3 and SSBRI/CRI #4 are respectively corresponding to one piece of beam link quality information.
In an implementation, when the reference signal resource indicator corresponds to a plurality of pieces of beam link quality information, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending may be determined based on the reference signal resource indicator corresponding to the plurality of pieces of beam link quality information. For example, in the beam report 2, because both SSBRI/CRI #1 and SSBRI/CRI #2 correspond to two L1-RSRP/L1-SINRs, it may be understood that the terminal performs beam measurement on each SSB or CSI-RS by using two panels and reports two pieces of beam link quality information. The corresponding two pieces of beam information for uplink sending may be determined based on two pieces of beam information for downlink reception used by the terminal when measuring the two pieces of beam link quality information corresponding to SSBRI/CRI #1. Alternatively, the corresponding two pieces of beam information for uplink sending may be determined based on two pieces of beam information for downlink reception used by the terminal when measuring the two pieces of beam link quality information corresponding to SSBRI/CRI #2. In this way, two pieces of beam information of uplink signals that the terminal is capable of simultaneously sending are determined. In other words, the RS resource indicated by SSBRI/CRI #1 or SSBRI/CRI #2 is used as the source reference signal of the uplink channel or the uplink RS. Accordingly, when the reference signal resource indicator corresponds to only one piece of beam link quality information, a plurality of pieces of beam information of uplink signals that are capable of being simultaneously sent cannot be determined, for example, for SSBRI/CRI #3 and SSBRI/CRI #4.
In another implementation, the beam report may further include:
In another implementation, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending may be further determined based on an arrangement order or a position of the reference signal resource indicator in the beam report, which may be agreed upon through a protocol or configured by a network side. For example, for the beam report 1, beam information corresponding to the first two arranged reference signal resource indicators may be determined as beam information of uplink signals that are capable of being simultaneously sent.
In an implementation, when determining the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending, a reference signal indicated by the reference signal resource indicator, that is, an SSB Resource or CSI-RS Resource, may be configured as a source reference signal of the beam information, that is, configured as a source reference signal in TCI state information, QCL information, or spatial relation information.
A format of the beam report in this embodiment of this application may be considered as a non-group-based beam report. In an implementation, before step S210, the method further includes:
The terminal receives third indication information from the network side device, where the third indication information is used to indicate that the beam report to be reported by the terminal includes a non-group-based beam report.
It can be learned from the technical solution of the foregoing embodiment that, in this embodiment of this application, the beam report includes at least one of the following: the reference signal resource indicator; the first index corresponding to the reference signal resource indicator, where the first index is used to indicate the first information of the terminal; the beam link quality information corresponding to the reference signal resource indicator; or the second indication information corresponding to the reference signal resource indicator. Therefore, the network side device is capable of quickly determining, based on the beam report, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending, and indicating the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending, thereby improving resource utilization efficiency.
Based on the foregoing embodiment, the beam report may include at least one of the following:
For example, a beam report 3 is shown as follows:
It can be learned that the beam report 3 includes four groups: a 1st resource group, a 2nd resource group, a 3rd resource group, and a 4th resource group, and each group includes two reference signal resource indicators.
In an implementation, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending may be determined based on the reference signal resource indicator included in the group. For example, by default, N pieces of beam information corresponding to a plurality of reference signal resource indicators included in each group are the N pieces of beam information of uplink signals that are capable of being simultaneously sent. For example, in the beam report 3, uplink signals are capable of being simultaneously sent based on two pieces of beam information corresponding to two reference signal resource indicators included in each group.
In another implementation, the beam report further includes a first index respectively corresponding to a reference signal resource indicator included in the group, where the first index is used to indicate first information of the terminal.
For example, a beam report 4 is shown as follows:
It can be learned that a first index corresponding to each reference signal resource indicator in the group is added to the beam report 4 compared with the beam report 3.
In an implementation, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending may be determined based on reference signal resource indicators that are included in the group and that correspond to different first indexes. For example, if indexes respectively corresponding to SSBRI/CRI #1 and SSBRI/CRI #2 in the 1st resource group is different, beam information corresponding to SSBRI/CRI #1 and SSBRI/CRI #2 may be determined as beam information of uplink signals that are capable of being simultaneously sent.
If first indexes corresponding to the reference signal resource indicators included in the group are the same, it may be determined that downlink signals are capable of being simultaneously received based on beam information of the reference signal resource indicators included in the group, that is, corresponding downlink channels or downlink reference signals are capable of being simultaneously received. In this case, beam information corresponding to a plurality of SSBRI/CRIs in one group is from one panel of the terminal. Therefore, only downlink multiple beams are capable of being simultaneously received, but uplink multiple beams are not capable of being simultaneously sent.
If first indexes corresponding to the reference signal resource indicators included in the group are different, it may be determined that uplink signals are capable of being simultaneously sent based on N pieces of beam information corresponding to the reference signal resource indicators included in the group, and downlink signals are capable of being simultaneously received.
In each group, a quantity of pieces of beam link quality information corresponding to the reference signal resource indicator may be one or more.
For example, a beam report 5 is shown as follows:
In an implementation, when at least one reference signal resource indicator in the reference signal resource indicators included in the group corresponds to a plurality of pieces of beam link quality information, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending may be determined based on the reference signal resource indicator that is in the group and that corresponds to the plurality of pieces of beam link quality information.
If the reference signal resource indicators included in the group each correspond to a plurality of pieces of beam link quality information, uplink signals are capable of being simultaneously sent based on N pieces of beam information corresponding to the reference signal resource indicators included in the group. For example, if SSBRI/CRI #1 and SSBRI/CRI #2 that are included in the 1st resource group in the beam report 5 each correspond to two pieces of beam link quality information, uplink signals are capable of being simultaneously sent based on beam information corresponding to SSBRI/CRI #1 and beam information corresponding to SSBRI/CRI #2. Alternatively, two pieces of beam information for uplink sending may be determined based on two pieces of beam information that correspond to SSBRI/CRI #1 and that are for downlink reception, to simultaneously send uplink signals. Alternatively, two pieces of beam information for uplink sending may be determined based on two pieces of beam information that correspond to SSBRI/CRI #2 and that are for downlink reception, to simultaneously send uplink signals.
If the reference signal resource indicators included in the group each correspond to only one piece of beam link quality information, uplink signals are not capable of being simultaneously sent based on beam information corresponding to the reference signal resource indicators included in the group, for example, the 3rd resource group and the 4th resource group in the beam report 5.
If the reference signal resource indicators included in the group includes a reference signal resource indicator corresponding to a plurality of pieces of beam link quality information and a reference signal resource indicator corresponding to only one piece of beam link quality information, uplink signals are capable of being simultaneously sent based on N pieces of beam information corresponding to the reference signal resource indicator corresponding to the plurality of pieces of beam link quality information, for example, SSBRI/CRI #3 of the 2nd resource group in the beam report 5. However, uplink signals are not capable of being simultaneously sent based on beam information corresponding to the reference signal resource indicator corresponding to only one piece of beam link quality information, for example, SSBRI/CRI #4 of the 2nd resource group in the beam report 5.
In another implementation, the beam report may further include fourth indication information corresponding to the group, where the fourth indication information is used to indicate at least one of the following:
For example, a beam report 6 is shown as follows:
It can be learned that in the beam report 6, a piece of fourth indication information corresponding to each group is I1, I2, I3, and I4.
In an implementation, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending may be determined based on content indicated by the fourth indication information. For example, if the fourth indication information is 1 bit, when the fourth indication information is 1, it indicates that uplink signals are capable of being simultaneously sent and downlink signals are capable of being simultaneously received based on beam information corresponding to a reference signal resource indicator included in a group corresponding to the fourth indication information. When the fourth indication information is 0, it indicates that only downlink signals are capable of being simultaneously received based on beam information corresponding to a reference signal resource indicator included in a group corresponding to the fourth indication information.
In another implementation, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending may be further determined based on an arrangement order or a position of the group in the beam report, which may be agreed upon through a protocol or configured by a network side. For example, for the beam reports 4 to 6, beam information corresponding to reference signal resource indicators included in the first two groups may be determined as beam information of uplink signals that are capable of being simultaneously sent.
A format of the beam report in this embodiment of this application may be considered as a group-based beam report. In an implementation, before step S210, the method further includes:
The terminal receives fifth indication information from the network side device, where the fifth indication information is used to indicate that the beam report to be reported by the terminal includes a group-based beam report.
In an implementation, when determining the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending, a reference signal indicated by the reference signal resource indicator may be configured as a source reference signal of the beam information.
It can be learned from the technical solution of the foregoing embodiment that, in this embodiment of this application, the beam report includes at least one of the following: the group including at least one reference signal resource indicator; the beam link quality information respectively corresponding to the reference signal resource indicator included in the group; the first index respectively corresponding to the reference signal resource indicator included in the group, where the first index is used to indicate the first information of the terminal; or the fourth indication information corresponding to the group. Therefore, the network side device is capable of quickly determining, based on the beam report, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending, and indicating the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending, thereby improving resource utilization efficiency.
Based on the foregoing embodiment, the beam report may use a beam report of a mixed type including any combination of one or more of the above non-group-based beam report and group-based beam report.
For example, a beam report 7 is shown as follows:
The beam report further includes indication information corresponding to each reference signal resource indicator and each group, which is equivalent to the second indication information corresponding to each reference signal resource indicator and the fourth indication information corresponding to each group.
N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending may be determined based on each piece of indication information. For example, based on an indicator of the indication information, it is determined whether the reference signal resource indicator corresponding to the indication information or the reference signal resource indicator in the group can be used to determine the N pieces of beam information of uplink signals that are capable of being simultaneously sent. The beam report may only have corresponding indication information for a group. In this case, the indication information is used to indicate whether a group corresponding to the indication information can be used to determine the N pieces of beam information of uplink signals that are capable of being simultaneously sent. Alternatively, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending may be determined based on an arrangement order or a position of each reference signal resource indicator and each group in the beam report. For example, Indication #1 and Indication #2 indicate that SSBRI/CRI #1 and SSBRI/CRI #2 cannot be used to determine the N pieces of beam information of uplink signals that are simultaneously sent, but can only be used to determine a single piece of beam information. In this case, Indication #1 and Indication #2 may alternatively be defaulted. For another example, Indication #3 indicates that two SSBRI/CRIs in the 1st resource group can be used to determine two pieces of beam information of uplink signals that are simultaneously sent, and Indication #4 indicates that two SSBRI/CRIs in the 2nd resource group cannot be used to determine two pieces of beam information of uplink signals that are simultaneously sent.
In an implementation, the non-group-based and group-based beam report of the mixed type, before step S210, may be configured by receiving sixth indication information of the network side device, where the sixth indication information may be new indication information, or may include the third indication information and the fifth indication information.
It can be learned from the technical solution of the foregoing embodiment that, in this embodiment of this application, the beam report includes any combination of one or more of the non-group-based beam report and the group-based beam report. Therefore, the network side device is capable of quickly determining, based on the beam report, the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending, and indicating the N pieces of beam information of uplink signals that the terminal is capable of simultaneously sending, thereby improving resource utilization efficiency.
The information transmission method provided in this embodiment of this application may be performed by an information transmission apparatus.
