In order to facilitate a clearer understanding of the technical solutions provided in the embodiments of the present application, some relevant background knowledge is first described below.
Signal amplifiers are widely used to extend the coverage of cells. The NCR, as a relay node, may forward signals from a base station or UE and amplify the signals. The NCR may receive control from an upstream base station (donor), i.e., the base station may control the transmission parameters of the NCR to improve the spectral efficiency of NCR signal forwarding, e.g., the receive/transmit beam between the NCR and the base station or between the NCR and the UE.
Fig. 2 is a schematic diagram of a prior art base station-NCR-UE establishing a transmission link. The network structure shown in fig. 2 includes three network nodes, namely a Base Station (BS), NCR equipment and UE; wherein the NCR device comprises a terminal module (Mobile Termination, MT) and a relay unit (Fwd), wherein the MT can establish a connection with an upstream base station via a control link (control link);
the base station transmits control signaling, such as transmission/reception related parameters of a backhaul link (BH) between the NCR and the base station, to the NCR through the MT; alternatively, transmission/reception-related parameters (related parameters including power, amplification, beam, on/off, etc.) of a forward link (AL) between the NCR and the UE are controlled.
The NCR requires transparency to the UE in the network when the protocol is designed, i.e. the UE behavior is the same for an access cell through the NCR and for a direct access cell by the UE, and the UE cannot perceive whether to access the cell through the NCR or directly. In order to improve the communication efficiency of the NCR, the backhaul link and the access link of the NCR need to introduce a transmit-receive beamforming technology to transmit signals. Thus, the system needs to support NCR-based beam training procedures.
The use of beam index to indicate the beam of the forward link is determined in the related art. That is, the base station instructs the operation time slot of the beam corresponding to the beam number to schedule the NCR to transmit the downlink signal or receive the uplink signal according to the beam corresponding to the beam number in the corresponding time slot. The beam number is used to indicate both the downlink transmit beam and the uplink receive beam of the NCR, i.e., the transmit spatial filtering (Tx spatial domain filter) of the downlink signal and the receive spatial filtering (Rx spatial domain filter) of the uplink signal indicated by the beam number are corresponding.
For the second frequency range (FR 2) system, the UE needs to perform beam training to obtain a fine beam for communication. After the UE accesses the cell according to the synchronous signal block (Synchronization Signal Block, SSB) wave beam, the signal quality of a plurality of CSI-RS wave beams/UE-specific wave beams quasi co-located with the SSB wave beam/cell-specific wave beam is measured, and then the wave beam for data communication is determined.
In communication systems based on NCR forwarding, for a base station-NCR-terminal link, terminal beam training is training the beam between the NCR and the terminal, i.e. the transmit/receive beam of the NCR forward link. The base station achieves beam training of the NCR and the terminal by instructing the NCR to forward the CSI-RS in different beam index beams.
Therefore, before the NCR access cell starts to operate, the base station needs to determine the association relationship between each beam index of the NCR and the reference signal of beam training, and the association relationship between each beam index and the SSB/CSI-RS.
The beam determining method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.
Fig. 3 is one of the flow diagrams of the beam determining method provided in the embodiment of the present application, as shown in fig. 3, the method includes step 301; wherein:
step 301, the communication equipment acquires first information; the first information is used for indicating beam index beam numbers corresponding to a first type beam and a second type beam in a beam set of a forward link of the communication equipment, the first type beam is used for transmitting broadcast signals, and the second type beam is used for transmitting data signals.
It should be noted that the embodiments of the present application may be applied to a scenario where a UE performs beam training. The communication device is for example an NCR.
In order to ensure that the NCR is consistent with the beam index understanding of the network side device for each beam, ambiguity is avoided when the network side device indicates the NCR, so that the UE and the NCR implement a beam training procedure, and in this embodiment, the communication device needs to acquire first information.
Alternatively, the first type of beam is, for example, a wide beam; the wide beam is used for transmitting and receiving broadcast signals such as SSB, a signal corresponding to a physical random access channel (Physical Random Access Channel, PRACH), COREET #0, etc.
The second type of beam is, for example, a narrow beam; the narrow beam is used for transmitting/receiving a signal of data traffic, for example, a signal of data traffic corresponding to a physical downlink shared channel (Physical downlink shared channel, PDSCH), a signal of data traffic corresponding to a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), and the like.
It is understood that the first information is used to indicate beam index corresponding to a wide beam for transmitting a broadcast signal and a narrow beam for transmitting a data signal in a beam set of a forward link of the communication device.
In the beam determining method provided by the embodiment of the application, the communication device obtains the first information, so that the beam numbers corresponding to the first type of beam and the second type of beam in the beam set for indicating the forward link can be obtained, the first type of beam is used for transmitting broadcast signals, and the second type of beam is used for transmitting data signals, and the beam numbers of the beams in the communication device are determined.
Optionally, the first information includes at least one of:
a) The total number of beams supported by the communication device;
optionally, among beams supported by the communication device, each beam corresponds to one beam index; for example, the beam index for the N beams is {0,1,...
b) The number of first type beams in the set of beams;
the first type of beam is a wide beam, and is used for transmitting and receiving broadcast signals, such as SSB, signals corresponding to physical random access channel (Physical Random Access Channel, PRACH), and coreet#0.
Optionally, the beam index corresponding to the first N1 beams in the beam set of the default forward link is the beam index corresponding to the wide beam, e.g., in the beam set of the forward link, the beam index corresponding to the wide beam is {0,1, …, N1-1} or {1,2, …, N1}.
c) The number of second type beams in the set of beams;
optionally, the second type of beam is a narrow beam, and is used for transmitting/receiving signals of data traffic, such as signals of data traffic corresponding to a physical downlink shared channel (Physical downlink shared channel, PDSCH) and signals of data traffic corresponding to a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).
Note that, the total number of beams supported by the communication device in the beam set of the forward link=the number of beams of the first type in the beam set+the number of beams of the second type in the beam set, that is, n1+n2=n.
By default, among the N beams in the beam set, beam index not indicated as a wide beam is beam index of a narrow beam.
d) The first indication information is used for indicating beam index corresponding to a first type of beam in the beam set;
specifically, the first indication information may be divided into a display indication and an implicit indication; under the condition that the first indication information is a display indication, the first indication information comprises beam index corresponding to a first type of beam in a beam set; for example { n } 1 ，n 2 ，...，n N1 }；
In the case that the first indication information is an implicit indication, the first indication information may be a bitmap (bitmap) of length N to indicate a beam index corresponding to the first type beam. For example, N1 positions assigned to "1" in the bitmap correspond to beam index of the first type beam.
e) The second indication information is used for indicating beam index corresponding to the second type of beams in the beam set;
specifically, the second indication information may be divided into a display indication and an implicit indication; wherein, when the second indication information is a display indication, the second indication information is a beam index corresponding to a second type of beam in the beam set;
in the case where the second indication information is an implicit indication, the second indication information may be a bitmap (bitmap) of length N to indicate a beam index corresponding to the second type beam.
f) A quasi co-located QCL relationship between the first type of beam and the second type of beam in the set of beams;
specifically, the QCL relationship may be defined by protocol default, such as QCL Type C and QCL Type D; or actively reported by the NCR.
The quasi-co-located QCL relationship between the wide beam (first type beam) and the narrow beam (second type beam) is two signals of the quasi-co-located QCL relationship NCR between the wide beam and the narrow beam when the UE receives the wide beam signal transmitted by the NCR and the narrow beam signal transmitted by the NCR. It is understood that one NCR wide beam establishes a QCL relationship with a plurality of narrow beams.
Optionally, a QCL relationship exists between a single first type beam and M second type beams in the beam set; the M second type beams are mapped into a set of beam index in a sequential order.
Specifically, for example, the number of second type beams associated with each first type beam is equal by default, that is, N2/N1 narrow beams are associated with each wide beam, and the narrow beams corresponding to each wide beam are mapped into the beam index set sequentially in succession.
For example, a broad beam with beam index i, and the corresponding narrow beam index set is n1+i n2/n1+ {0,1, … N2/N1-1}, i= {0, … N1-1}.
And reporting the beam index corresponding to the wide beam displayed by the NCR, wherein the beam index following the wide beam index defaults to be a narrow beam, and the QCL relationship is ensured with the wide beam.
For example, the wide beam index is arranged in ascending order { n1, n2, … nN1}. The narrow beam index associated with the wide beam index n1 is { n1+1, n1+2, …, n2-1}.
g) The beam gains of the first type of beams in the set of beams.
h) The beam gain of the second type of beam in the set of beams.
i) The second type of beam in the set of beams has a beam gain relative to the first type of beam.
Optionally, after the communication device acquires the first information, the first information needs to be reported to the network side device, so that the network side device acquires beam index corresponding to the first type beam and the second type beam, and the network side device can configure the working state of the forward link for the communication device based on the beam index; the method can be realized by the following steps 1) to 3):

step 2), the communication equipment receives first configuration information from the network side equipment; the first configuration information is used for indicating configuration information of each beam in the beam set;

c) Offset of the amplification factor of the second type of beam relative to the first type of beam.
In the above embodiment, the communication device reports, to the network side device, the beam numbers corresponding to the first type of beam used for transmitting the broadcast signal and the second type of beam used for transmitting the broadcast signal in the beam set of the forward link, where the network side device can ensure that the communication device and the network side device have consistent understanding on the indication mode and the correspondence relationship of the first type of beam and the second type of beam based on the beam numbers of the first type of beam and the second type of beam; the network side equipment indicates the configuration information of each beam in the beam set of the forward link to the communication equipment based on the first information, so that the communication equipment can determine the working state of the forward link based on the first information and the configuration information of each beam in the beam set of the forward link, and further, the beam switching of the forward link is realized in the process of carrying out beam training on the communication equipment and the UE, so that the beam training process of the UE is not affected, and the beam training process of the communication equipment and the UE is realized.
