As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0043] The transmission processing method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0044] like Figure 2 As shown, the transmission processing method of the embodiment of the present application includes:

[0045] Step 201: The relay device receives beam-related indication information from a network-side device.

[0046] Step 202: The relay device determines a first beam according to the beam-related indication information;

[0047] Step 203: The relay device transmits a reference signal using the first beam;

[0048] The first beam includes a transmitting beam and / or a receiving beam; the reference signal includes a transmitting reference signal and / or a receiving reference signal.

[0049] In this way, according to the above steps 201-203, after receiving the beam-related indication information from the network side device, the relay device will determine the first beam based on the beam-related indication information, and thereby use the first beam to transmit the reference signal. The reference signal is a sending reference signal and / or receiving reference signal between the relay device and the remote terminal, thereby realizing the control of the transmission between the relay device and the remote terminal by the network side device and ensuring the transmission quality.

[0050] Here, the first beam includes a transmit beam and / or a receive beam. Accordingly, a transmit beam is used to transmit a signal, which is a transmit reference signal (downlink reference signal); a receive beam is used to receive a signal, which is a receive reference signal (uplink reference signal).

[0051] It should be noted that, in this embodiment, the reference signal is used for training a transmission beam used for transmission between the relay device and the remote terminal, or the reference signal is used for channel estimation between the relay device and the remote terminal.

[0052] Optionally, the first beam belongs to a candidate beam set;

[0053] Before step 202, the following steps are also included:

[0054] The relay device determines the candidate beam set.

[0055] In this way, the relay device can determine the first beam in combination with the candidate beam set in step 202. Of course, the candidate beam set can also be used to guide the network-side device to generate beam-related indication information corresponding to the beams in the candidate beam set. The candidate beam set may include one or more beams.

[0056] Optionally, the relay device determines the candidate beam set, including:

[0057] The relay device determines the candidate beam set based on autonomously set beam preset information; or

[0058] The relay device determines the candidate beam set based on the beam preset information of the network side device.

[0059] That is, the candidate beam set can be determined by the repeater autonomously or by the network-side device.

[0060] Optionally, the beam preset information includes at least one of the following:

[0061] The number of beams in the candidate beam set;

[0062] The candidate beams are radiation patterns of beams in the set.

[0063] Here, the radiation pattern of the beam may include the uplink and downlink scanning angle range of the beam, the beam direction, the lobe width, etc.

[0064] The network-side device's beam preset information is sent by the network-side device to the relay device. Regarding the beam preset information independently set by the relay device, in order to enable the network-side device to understand the candidate beam set, the relay device may optionally, after determining the candidate beam set based on the independently set beam preset information, further include:

[0065] The relay device sends the autonomously set beam preset information to the network side device.

[0066] Therefore, the network-side device is similar to the relay device and can also determine the candidate beam set based on the autonomously set beam preset information or the beam preset information of the relay device, and guide the generation of beam-related indication information.

[0067] In this embodiment, the number of beams in the candidate beam set included in the beam preset information may be the number of all beams in the candidate beam set, or the number of expected or available beams in the candidate beam set.

[0068] The candidate beam sets can be divided into independent candidate transmit beam sets and candidate receive beam sets based on whether the beams are used for transmission or reception. Alternatively, the candidate beam sets can be combined into the same candidate beam set without distinguishing between transmit beams and receive beams, and can be used as both candidate transmit beam sets and candidate receive beam sets. The independent candidate transmit beam sets and candidate receive beam sets are compatible with various repeater hardware structures.

[0069] The relay device determines the candidate beam set and can send an indication to the network device to report whether the candidate transmit beam set and the candidate receive beam set are the same or independent of each other. The network device determines the candidate beam set and can send an indication to the relay device to indicate whether the candidate transmit beam set and the candidate receive beam set are the same or independent of each other.

[0070] Optionally, the beams in the candidate beam set have associated beam identifiers;

[0071] Wherein, the beam identifier is a preset identifier; or,

[0072] The beam identifier is a resource identifier of a reference signal.

[0073] Here, the preset identifier is preset and dedicated to identifying the beam, and the beam in the candidate beam set can be directly associated with the preset identifier. Alternatively, the beam in the candidate beam set can also be associated with the resource identifier of the reference signal, that is, the resource identifier of the reference signal is used to identify the beam, such as for downlink beams, using the synchronization signal block (Synchronization Signal and PBCH block, SSB) identifier (index) or the channel state information reference signal (CSI-RS) resource identifier (resource index) to identify; for uplink beams, using the channel sounding reference signal (SRS) resource index to identify.

[0074] Optionally, the beam identifier satisfies at least one of the following conditions:

[0075] The beam identification corresponds to the beam radiation pattern;

[0076] The same beam identifier indicates the same transmit beam;

[0077] The same beam identifier indicates the same receive beam;

[0078] The same beam identifier indicates the same transmit and receive beam;

[0079] The identification of the transmit beam and the receive beam are independent of each other;

[0080] Beams with different beam identifiers are indicated as the same beam using a quasi-co-located QCL relationship.

[0081] The correspondence between the beam identifier and the beam radiation pattern can be determined by the relay device, predefined, or configured by the network-side device. The same beam identifier indicates the same transmit beam, the same beam identifier indicates the same receive beam, and the same beam identifier indicates the same transmit and receive beam, that is, for the same beam identifier, the repeater uses the same beam / spatial filter. Beams with different beam identifiers are indicated as the same beam using a quasi-co-located QCL relationship, that is, beams with different beam identifiers can have a QCL relationship (such as QCL type D), and the repeater uses the same spatial filter for beams with a QCL relationship.

[0082] Optionally, the beam-related indication information includes at least one of the following:

[0083] a third beam associated with the reference signal transmission beam;

[0084] repetition information of a beam used for transmitting reference signals in a reference signal set, the repetition information being used to indicate whether the beams used for transmitting reference signals in the reference signal set are the same beam;

[0085] The mapping relationship between reference signal transmission resources and reference signal transmission beams.

[0086] If the beam-related indication information includes a third beam associated with the reference signal transmission beam, that is, the network-side device directly indicates the beam used for reference signal transmission, then, optionally, step 202 includes:

[0087] In a case where the beam-related indication information includes the third beam, the relay device uses the third beam as the first beam.

[0088] For example, the reference signal is a downlink reference signal used for repeater-UE downlink beam training, and a network-side device such as a base station sends beam-related indication information including a third beam associated with the downlink reference signal transmission beam, and the relay device uses the third beam to send the corresponding downlink reference signal to the corresponding remote terminal. The beam-related indication information includes the beam identifier of the third beam. Alternatively, the reference signal is an uplink reference signal used for UE-repeater uplink beam training, and a network-side device such as a base station sends beam-related indication information including a third beam associated with the uplink reference signal transmission beam, and the relay device uses the third beam to receive the uplink reference signal from the corresponding remote terminal. The beam-related indication information can indicate the third beam through the beam identifier of the third beam.

[0089] Of course, the third beam is effective on the time-frequency domain resources where the reference signal is located.

[0090] In this embodiment, the repetition information of the beam used for reference signal transmission in the reference signal set may also be referred to as the repetition on / off characteristic. Repetition on means that the beam used for reference signal transmission in the reference signal set is the same beam; repetition off means that the beams used for reference signal transmission in the reference signal set are different beams. For example, for repeater-UE downlink beam training, the repetition on / off characteristic is set as follows: when performing relay device downlink transmit beam (repeater DL TX beam) training, the repeater transmit beam appears in the repetition off mode; when performing remote terminal downlink receive beam (UE DL RX beam) training, the downlink reference signal is transmitted in the repetition on mode. Alternatively, for UE-repeater uplink beam training, the repetition on / off feature is set as follows: when performing repeater UL RX beam training, the uplink reference signal is received in repetition off mode; when performing remote terminal uplink receive beam training (UE UL TX beam), the uplink reference signal is sent in repetition on mode.

[0091] The repetition information can be indicated by the number of repetitions. When the number of repetitions is 0, repetition is turned off. When the number of repetitions is greater than 0, repetition is turned on and repeated N times according to the number of repetitions, where N is equal to the number of repetitions. During the repetition period, if there is only one first beam, the corresponding reference signal is repeatedly transmitted multiple times on the first beam, that is, the same beam. If there are multiple first beams, different beams may be used to transmit the corresponding reference signal.

[0092] If the beam-related indication information includes repeated information about the beam used for reference signal transmission in the reference signal set, and the network-side device does not directly indicate the first beam, it is necessary to determine the first beam based on whether the beam-related indication information also includes a reference beam indication. Therefore, optionally, step 202 includes:

[0093] In a case where the beam-related indication information includes the repetition information and the beam-related indication information contains a reference beam indication, the relay device uses the reference beam indicated by the reference beam indication as the first beam, or determines the first beam based on the reference beam indicated by the reference beam indication.

[0094] In this embodiment, the reference beam indication is used to indicate a reference beam. The reference beam indication can be a beam identifier of one or more reference beams; it can also be a resource identifier of a reference signal. For example, for repeater-UE downlink beam training, the reference beam can be indicated by the resource identifier of a downlink reference signal (such as SSB or CSI-RS), that is, the beam corresponding to the resource sent by the repeater is the reference beam. In this case, the reference beam is the beam through which the repeater sends the downlink reference signal. For UE-repeater uplink beam training, the reference beam can be indicated by the resource identifier of an uplink or downlink reference signal, that is, the beam corresponding to the resource sent and received by the repeater is the reference beam.

[0095] In this way, the relay device can directly use the reference beam as the first beam. For example, the beam-related indication information includes repetition on and reference beam indication. For repeater-UE downlink beam training, the repeater uses the reference beam to send the downlink reference signal; for UE-repeater uplink beam training, the repeater uses the reference beam to receive the uplink reference signal.

[0096] Alternatively, the relay device determines the first beam based on the reference beam. For example, the beam-related indication information includes repetition off and reference beam indication. For repeater-UE downlink beam training, the network-side device (donor) can indicate the trained available transmit beam (coarse TX beam) to the repeater as the reference beam, and the repeater further independently determines the finer TX beams to be trained based on the coarse TX beam, that is, the first beam; for UE-repeater uplink beam training, the donor can indicate the trained available receive beam (coarse RX beam) to the repeater as the reference beam, and the repeater further independently determines the finer RX beams to be trained based on the coarse RX beam, that is, the first beam.

[0097] Wherein, finer TX beams are subdivided beams within the beamwidth of the coarse TX beam, or the total coverage width of finer TX beams is within the beamwidth of the coarse TX beam or the subdivided beams with adjacent beamwidths. Similarly, finer RX beams are subdivided beams within the beamwidth of the coarse RX beam, or the total coverage width of finer RX beams is within the beamwidth of the coarse RX beam or the subdivided beams with adjacent beamwidths.

[0098] In this embodiment, whether it is repeater-UE downlink beam training or UE-repeater uplink beam training, the network-side device can configure the repeater's beam scanning mode: horizontal scanning, vertical scanning, or horizontal and vertical mixed scanning. Based on the configured beam scanning mode, a training beam of the repeater is allocated to the left and right of the reference beam (corresponding to vertical scanning), up and down (corresponding to horizontal scanning), and horizontal and vertical scanning (corresponding to mixed scanning). Of course, the allocation of training beams to the reference beam can be predefined as symmetrical allocation. For example, the network-side device configures three training beams and one reference beam for the repeater. Assuming that the reference beam corresponds to beam X and uses horizontal beam scanning, the repeater performs beam scanning on beam X-1, beam X, and beam X+1 in sequence.

[0099] If the beam-related indication information does not include a reference beam indication, step 202 may optionally include:

[0100] In a case where the beam-related indication information includes the repetition information and the beam-related indication information does not include a reference beam indication, the relay device autonomously determines the first beam, or determines the first beam based on a preset beam.

[0101] Here, the preset beam is predefined or preconfigured, such as configured by a network side device.

[0102] In this embodiment, the beam-related indication information includes a mapping relationship between reference signal transmission resources and reference signal transmission beams. In this way, when the downlink reference signal resource is located in a certain time / frequency resource, the repeater determines and uses the corresponding repeater beam to send the downlink reference signal; when the uplink reference signal is located in a certain time / frequency resource, the corresponding repeater beam is used to receive the uplink reference signal.

[0103] In addition, optionally, after step 202, the method further includes:

[0104] In a case where the first beam is a downlink beam for sending a reference signal, the relay device sends beam information of the first beam to the network side device.

[0105] That is, when the repeater uses the first beam (downlink beam) to send a downlink reference signal, it reports the beam information of the first beam, such as the beam identifier of the first beam, so that the network-side device can effectively adjust the first beam in the case of multiple UEs. For example, when performing repeater downlink beam training, when the repeater reports the downlink reference signal transmission to the donor, it reports the beam information of the corresponding downlink reference signal transmission beam.

[0106] In this embodiment, if the reference signal is used to train the beam used for transmission between the relay device and the remote terminal, for repeater-UE downlink beam training, the UE reports the measurement result of the downlink reference signal to the network-side device, and the network-side device determines the final repeater-UE downlink transmission beam; for UE-repeater uplink beam training, the repeater receives the uplink reference signal from the corresponding UE according to the first beam, and the network-side device measures the uplink reference signal and determines the final UE-repeater uplink transmission beam based on the measurement result. In this way, in order to achieve high-quality transmission between the relay device and the remote terminal, the network-side device sends transmission beam indication information to indicate the transmission beam used for transmission between the relay device and the remote terminal. The corresponding relay device, optionally, after executing step 203, also includes:

[0107] The relay device receives transmission beam indication information sent by the network side device, where the transmission beam indication information is used to indicate the transmission beam used for transmission between the relay device and the remote terminal.

[0108] Here, a transmission beam includes an uplink beam (uplink transmission beam) and / or a downlink beam (downlink transmission beam). The transmission beam indication information is not limited to a single transmission beam and can be a group of transmission beams. The relay device and the remote terminal can then use the transmission beam or the group of transmission beams for transmission.

[0109] Optionally, the one or group of transmission beams are beams in the first beam group.

[0110] In this embodiment, optionally, the beam-related indication information further includes: reference signal resource indication information;

[0111] The reference signal resource configuration information includes at least one of the following:

[0112] downlink reference signal resource indication information;

[0113] Resource indication information of uplink reference signal.

[0114] In this embodiment, the downlink reference signal is a relay device-specific downlink reference signal, such as a repeater-specific CSI-RS, and the uplink reference signal is a relay device-specific uplink reference signal, such as a repeater-specific SRS.

[0115] Optionally, the reference signal resource indication information includes at least one of the following:

[0116] resource indication of reference signals;

[0117] Beam indication corresponding to the reference signal resource;

[0118] QCL relationship indication of the beam corresponding to the reference signal resource;

[0119] The repetition information of the beam corresponding to the reference signal in the reference signal set.

[0120] Here, the resource indication of the reference signal indicates the resource configuration for one or more reference signals. Optionally, the resource configuration of each reference signal includes one or more reference signal resource sets, and each reference signal resource set includes one or more reference signal resources. The beam indication corresponding to the reference signal resource indicates the beam used on the reference signal resource, and can be indicated by a beam identifier. Of course, the beam identifier can be a preset identifier for a dedicated indication beam, or a reference signal resource identifier. The QCL relationship indication of the beam corresponding to the reference signal resource can be configured for the reference signal resource or resource set, and the information with a QCL relationship is sent using the same beam. The repetition information of the beam corresponding to the reference signal in the reference signal set is also used to indicate whether the beam used for the reference signal transmission in the reference signal set is the same beam.

[0121] For example, for repeater-UE downlink beam training, the reference signal may be a repeater-specific CSI-RS, and the reference signal resource indication information includes a resource indication of the repeater-specific CSI-RS, indicating one or more repeater-specific CSI-RS resource configurations. Optionally, the repeater-specific CSI-RS resource configuration includes one or more repeater-specific CSI-RS resource sets, wherein the repeater-specific CSI-RS resource set includes one or more repeater-specific CSI-RS resources. The reference signal resource indication information includes a beam indication corresponding to the repeater-specific CSI-RS resource, such as using a preset identifier indication, or indicating in the form of a repeater-specific CSI-RS resource ID (i.e., the same repeater-specific CSI-RS resource ID corresponds to the same repeater transmit beam). The reference signal resource indication information includes the QCL relationship indication of the beam corresponding to the repeater-specific CSI-RS resource set or repeater-specific CSI-RS resource. The QCL relationship can be associated with the SSB identifier (index) or repeater-specific CSI-RS resource ID. Information with a QCL relationship is transmitted using the same repeater beam. The reference signal resource indication information includes repetition information (repetition on / off) for the beam corresponding to the repeater-specific CSI-RS in the repeater-specific CSI-RS set.

[0122] The CSI-RS sent by the repeater in the repeater-specific CSI-RS resource set can be generated by the repeater itself or forwarded from a network device. Optionally, the network device can indicate CSI-RS generation parameters and / or CSI-RS transmit power to the repeater.

[0123] In addition, the network side device may also notify the relay device of the trigger information sent by the repeater-specific CSI-RS.

[0124] It should be known that the remote terminal-specific downlink reference signal CSI-RS resource configuration may be a subset of the repeater-specific CSI-RS resource configuration.

[0125] For another example, for UE-repeater uplink beam training, the reference signal may be a repeater-specific SRS, and the reference signal resource indication information includes a resource indication of the repeater-specific SRS, indicating one or more repeater-specific SRS resource configurations. Optionally, the repeater-specific SRS resource configuration includes one or more repeater-specific SRS resource sets, wherein the repeater-specific SRS resource set includes one or more repeater-specific SRS resources. The reference signal resource indication information includes a beam indication corresponding to the repeater-specific SRS resource, such as using a preset identifier indication, or indicating in the form of a repeater-specific SRS resource ID (i.e., the same repeater-specific SRS resource ID corresponds to the same repeater receiving beam). The reference signal resource indication information includes the QCL relationship indication of the beam corresponding to the repeater-specific SRS resource set or the repeater-specific SRS resource. The QCL relationship can be associated with the SSB identifier (index) or the repeater-specific CSI-RS resource ID or the repeater-specific SRS resource ID. Information with a QCL relationship is sent using the same repeater beam. The reference signal resource indication information includes the repetition information (repetition on / off) of the beam corresponding to the repeater-specific SRS in the repeater-specific SRS set. Repetition on means that the repeater uses the same beam to receive the SRS on the corresponding resource.
