[0043] The transmission processing method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0044] like Figure 2 As shown in the figure, an embodiment of this application provides a transmission processing method, including:

[0045] Step 201: The network-side device sends beam indication information;

[0046] The beam indication information is used to indicate the transmission beam used by the relay device to transmit one or a group of first resources to the remote terminal; the transmission beam includes a transmit beam and / or a receive beam, and the first resource includes time domain resources and / or frequency domain resources.

[0047] In this way, the network-side device sends beam indication information to the relay device to indicate the transmission beam used by the relay device and the remote terminal for transmitting one or a group of first resources. After receiving the beam indication information, the relay device adopts the indicated transmission beam for the transmission on the one or a group of first resources, so as to realize the network side's control over the transmission between the relay device and the remote terminal and ensure higher transmission quality.

[0048] Here, network-side devices can specify the transmission beam they use for a resource or a set of resources, where the resource or set of resources can be a time-domain resource and / or a frequency-domain resource. For example... Figure 3 As shown, the beam indication information indicates that the transmission beam used by a group of resources (resources 0 to 2) is beam 1, and the transmission beam used by a group of resources (resources 6 to 7) is beam 2. The transmission beams used by other resources are not indicated.

[0049] Of course, the indicated transmission beam can be a transmit beam and / or a receive beam.

[0050] Optionally, the beam indication information is indicated in at least one of the following ways:

[0051] Semi-static indication;

[0052] Dynamic indicators.

[0053] Semi-static indicators can include Radio Resource Control (RRC) signaling indicators, F1 signaling, Media Access Control (MAC) control element (CE) indicators, and Physical Downlink Control Channel (PDCCH) indicators. Dynamic indicators can include MAC CE indicators and Downlink Control Information (DCI) indicators.

[0054] If semi-static beam indication information already exists, dynamic beam indication information can override it. For example, Figure 3 As shown, semi-static beam indication information indicates that a group of resources (resources 0-2) uses beam 1, and a group of resources (resources 6-7) uses beam 2. No beam indication information is provided for other resources. However, if dynamic beam indication information exists, indicating that resource 6 uses beam 3, then the relay device will transmit on resource 6 using beam 3 instead of beam 2.

[0055] Optionally, in this embodiment, the transmission beam is a fixed beam or a variable beam.

[0056] In other words, the network-side device can specify a fixed beam as the transmission beam used by the one or a group of first resources, or it can specify a variable beam as the transmission beam used by the one or a group of first resources.

[0057] Optionally, the network-side device indicates, through a semi-static indication, whether the transmission beam used by the first resource is a target fixed beam or a variable beam; wherein,

[0058] When the transmission beam is the target fixed beam, the network-side device indicates the beam information corresponding to the target fixed beam in a semi-static manner.

[0059] And / or, when the transmission beam is a variable beam, the network-side device sends beam indication information corresponding to the first resource in a dynamic indication manner.

[0060] That is, beam indication information is sent in a semi-static manner, and this beam indication information specifically indicates the beam information corresponding to one or more fixed beams (target fixed beams) in order to indicate the transmission beams used by one or a group of first resources. In this case, the target fixed beam is also the transmission beam.

[0061] The beam indication information sent via semi-static indication does not include the beam indication information corresponding to the first resource when the transmission beams used by one or more first resources are variable beams. This allows for dynamic adjustment of the resource allocation corresponding to a particular repeater beam based on the number of UEs or traffic load under different repeater beams. In other words, if the beam indication information does not indicate the transmission beams used by one or more first resources, it can be assumed that the transmission beams used by those first resources are variable beams. Subsequently, the network-side device will send beam indication information for the first resources using variable beams via dynamic indication.

[0062] Alternatively, the network-side device may send beam indication information corresponding to the first resource via dynamic indication, including:

[0063] Transmit a first DCI including the beam indication information;

[0064] Wherein, the first DCI is a specific DCI used for beam indication;

[0065] The specific DCI includes at least one of the following:

[0066] DCI in a specific format;

[0067] DCI corresponding to a specific wireless network temporary identifier RNTI;

[0068] DCI corresponding to a specific control resource set CORESET;

[0069] DCI corresponding to a specific search space SS.

[0070] In other words, the network-side device will use at least one of the following DCIs for beam indication: a DCI of a specific format, a DCI corresponding to a specific RNTI, a DCI corresponding to a specific CORESET, and a DCI corresponding to a specific SS. That is, it carries the aforementioned beam indication information to distinguish it from other DCIs. Of course, a specific field of the specific DCI can indicate that it is used for beam indication.

[0071] Optionally, for a specific DCI, the specific DCI is a group common DCI, and the group common DCI is pre-configured with a target domain for carrying the beam indication information.

[0072] That is, the specific DCI mentioned above is a Group Common DCI, such as the Group Common DCI corresponding to a specific RNTI, which can achieve the purpose of saving signaling overhead. In a specific Group Common DCI, a target domain is also pre-configured to carry beam indication information.

[0073] In this embodiment, the beam indication information may directly include the beam information of the indicated transmission beam. Optionally, for multiple or multiple groups of first resources, the beam indication information includes a first identifier, which is used to identify one or a group of transmission beams, and the one or a group of transmission beams are mapped to the one or a group of first resources, which helps to avoid causing large signaling overhead.

[0074] Here, one or a group of transmission beam identifiers are pre-defined, and these one or a group of transmission beams are mapped to one or a group of first resources. Thus, the beam indication information only needs to include the first identifier, and the relay device can use this first identifier to understand the beam information of the transmission beams used by the one or a group of first resources it is mapped to. For example, if the first identifier is dynamically indicated as 1, and the beam identified by the first identifier is beam A, then based on the mapping relationship between beam A and resource 1, the relay device knows that beam A is used for transmission on resource 1.

[0075] In this embodiment, optionally, if the first resource includes a time-domain resource, then the granularity of the time-domain resource is a time slot, a sub-time slot, or a symbol; and / or,

[0076] If the first resource includes frequency domain resources, then the granularity of the frequency domain resources is resource block group (RBG), physical resource block (PRB), serving cell, or sub-frequency band.

[0077] The granularity of frequency domain resources can be N RBGs, N PRBs, N serving cells, or N sub-bands; the granularity of time domain resources is per / N slots, per / N sub-slots, or per / N symbols. N is an integer greater than or equal to 1. Of course, the granularity of time domain resources and frequency domain resources can be predefined or configured.

[0078] In this embodiment, optionally, the wave transmission beam corresponds to a set of first resources, and the set of first resources is resources within a preset time period.

[0079] That is, the transmission beam indicated by the network-side device applies to multiple first resources within the preset time period. For example, such as Figure 4 As shown, the beam indication information indicates that the transmission beam used by the resource during time t1 is beam 1, and the transmission beam used by the resource during time t2 is beam 2.

[0080] Optionally, the one or a group of first resources appear at a preset period.

[0081] That is, the transmission beam indicated by the network-side device is applicable to one or a group of resources that appear periodically according to the preset schedule. For example, such as Figure 5 As shown, the beam indication information indicates that within one cycle, resources 0-3 use beam 1 for transmission, and resources 4-5 use beam 2 for transmission.

[0082] Of course, the resources applicable to the transmission beam indicated by semi-static indication and dynamic indication are different. For example, the transmission beam indicated by semi-static indication is applicable to multiple first resources within a preset time period; while the transmission beam indicated by dynamic indication is applicable to one or a group of first resources that appear in a preset period.

[0083] In this embodiment, optionally, the effective start time of the beam indication information is a preset time.

[0084] Here, the preset time can be predefined, configured on the network side, or determined and reported to the network side by the relay device. Specifically, the preset time can be the x-th time unit after the repeater receives the dynamic beam indication information. Thus, processing time or beam switching time can be reserved between receiving the beam indication information and the x-th time unit. x can be dynamically indicated by the network-side device or configured by RRC.

[0085] Optionally, step 201 includes:

[0086] The network-side device sends corresponding beam indication information based on the transmission direction of the first resource;

[0087] The transmission direction includes at least one of the following:

[0088] Uplink transmission;

[0089] Downlink transmission;

[0090] Flexible transmission.

[0091] In other words, network-side devices can independently send beam indication information corresponding to one or more transmission directions.

[0092] Optionally, step 201 includes:

[0093] The network-side device sends corresponding beam indication information based on the channel type of the first resource;

[0094] The channel type includes at least one of the following:

[0095] Physical Downlink Control Channel (PDCCH);

[0096] Physical Downlink Shared Channel (PDSCH);

[0097] Physical uplink control channel (PUCCH);

[0098] Physical uplink shared channel (PUSCH).

[0099] In other words, network-side devices can independently send beam indication information corresponding to one or more channels.

[0100] In addition, for beam indication information transmitted based on the channel type of the first resource, the network-side device can also indicate the time / frequency domain resource occupancy information of the channel.

[0101] Optionally, the network-side device sends corresponding beam indication information based on the channel type of the first resource, including:

[0102] When the channel type of the first resource is PDCCH, the network-side device sends first indication information, which includes the beam indication information;

[0103] The first indication information is valid in the relay level control resource set CORESET or search space SS.

[0104] Here, the repeater-level CORESET or SS is a CORESET or SS dedicated to relaying. The user-level CORESET or SS is a subset of the repeater-level CORESET or SS. Network-side equipment sends beam indication information. If this beam indication information indicates the transmission beam of the first resource on the PDCCH, it can be implemented by carrying this beam indication information in the first indication information. The first indication information is valid in the repeater-level CORESET or SS.

[0105] Optionally, the first indication information further includes at least one of the following:

[0106] CORESET's temporal resource location;

[0107] CORESET's frequency domain resource location;

[0108] Location of SS's temporal resources;

[0109] Location of SS's frequency domain resources.

[0110] Optionally, the transmission beam indicated by the beam indication information corresponds to the CORESET or SS of the relay level.

[0111] That is, the transmission beam indicated by the beam indication information corresponds to the first resource on the repeater-level CORESET or SS. In other words, the repeater, based on this beam indication information, transmits the PDCCH on the corresponding CORESET or SS using the indicated transmission beam.

[0112] Of course, a CORESET can be further divided into several sub-CORESETs, and the network-side equipment can further indicate the transmission beam of the first resource of the corresponding sub-CORESET. Similarly, an SS can be divided into several sub-CORESETs, and the network-side equipment can further indicate the transmission beam of the first resource of the corresponding sub-CORESET. This allows multiple UEs to share a single repeater-level CORESET / SS.

[0113] Optionally, after the network-side device sends the first indication information including the beam indication information, it further includes:

[0114] The network-side device sends a second indication information, which is used to indicate the timing or resources for PDCCH transmission when PDCCH transmission exists.

[0115] The beam indication information is valid during the PDCCH transmission timing or within the specified resources.

[0116] Here, the PDCCH transmission timings (monitoring occasion(s)) or resources (resource(s)) where PDCCH transmission exists can also be understood as PDCCH monitoring occasion(s) / resource(s) where PDCCH transmission is potentially present. The network-side device further clarifies, through the second indication information, that the beam indication information is valid for PDCCH transmission timings or resources where PDCCH transmission exists.

[0117] For example, such as Figure 6 Of the resources shown, for the three PDCCH transmission resources (resources with slashes in the background), only the second PDCCH transmission resource is the PDCCH transmission resource with PDCCH transmission indicated by the second indication information. Therefore, the beam indication information is only valid on the second PDCCH transmission resource.

[0118] The second indication information can be sent via higher-layer signaling (such as RRC or MAC CE) or via physical layer signaling (DCI). MAC CE is used to notify the second indication information; a MAC CE-specific LCID or a MAC CE-specific field indicates that the MAC CE contains the second indication information. DCI is used to notify the second indication information, using a specific DCI format / RNTI / CORESET / SS to distinguish the DCI containing the second indication information, or a specific field in the DCI indicating that the DCI contains the second indication information.

[0119] Optionally, step 201 includes:

[0120] The network-side device sends third indication information including the beam indication information, the third indication information being used to indicate resource scheduling at the relay level.

[0121] In other words, the beam indication of network-side equipment can be combined with relay-level resource scheduling. This third indication information can be the scheduling information of repeater-level PDCCH, PDSCH, PUCCH, or PUSCH. Here, the repeater-level scheduling information exists independently of the legacy UE's scheduling signaling and is only used by the repeater to demodulate the scheduling information.

[0122] Optionally, the third indication information further includes at least one of the following:

[0123] The location of time-domain resources to be scheduled;

[0124] Location of frequency domain resources to be scheduled;

[0125] The timing of the scheduled transmission or the temporal location of the resource;

[0126] The timing of transmission or the frequency domain location of resources that are scheduled;

[0127] The timing of reception or the temporal location of resources in the scheduling process;

[0128] The frequency domain location of the receiving opportunity or resource that is scheduled.

[0129] Here, the scheduled transmission timing or resource refers to the transmission timing or resource of a PDCCH or PDSCH transmission that is currently (or potentially) scheduled. The scheduled reception timing or resource refers to the reception timing or resource of a PUCCH or PUSCH transmission that is currently (or potentially) scheduled.

[0130] Optionally, the beam indication information included in the third indication information is valid in at least one of the following positions:

[0131] The scheduling exists at the timing of transmission or in the temporal location of the resource;

[0132] The scheduling exists at the transmission timing or in the frequency domain of the resource;

[0133] The scheduling exists at the receiving timing or in the temporal location of the resource;

[0134] The scheduling involves the reception timing or frequency domain location of the resources.

[0135] In other words, the repeater only needs to comply with the beam indication information in one or more of the above positions.

[0136] Optionally, the beam indication information transmitted via the third indication information has a higher priority than the beam indication information transmitted via semi-static indication and / or dynamic indication.

[0137] That is, beam indication information at the resource scheduling level can override beam indication information at the semi-static and / or dynamic levels.

[0138] Optionally, when semi-static scheduling is used for the downlink or cell group scheduling is used for the uplink, the beam indication information is indicated by semi-static scheduling.

[0139] That is, for the downlink using semi-static scheduling (DL SPS) or the uplink using cell group scheduling (UL(type 1)CG), the beam indication information is indicated in a semi-static manner.

[0140] Furthermore, in this embodiment, the beam indication information may contain transmission beams that do not indicate the use of certain resources for transmission between the relay device and the remote terminal. Therefore, when the relay device receives beam indication information that does not indicate the transmission beams used for transmission of the second resource between the relay device and the remote terminal, it will perform at least one of the following:

[0141] The second resource is transmitted using a preset beam;

[0142] The second resource is transmitted using the beam used in the previous transmission of the second resource;

[0143] Stop the transmission of the second resource;

[0144] Reduce the transmission power of the second resource;

[0145] The network-side device is requested to use the beam for the second resource transmission;

[0146] The system autonomously determines the beam used for the transmission of the second resource and sends it to the network-side device.

[0147] For example, a relay device has two pre-set receive beams (RX beams) for uplink reception with the remote terminal, labeled Q1 and Q2 respectively. It also has two pre-set transmit beams (TX beams) for downlink transmission with the remote terminal, labeled P1 and P2 respectively. The network-side device can then send beam indication information including Q1 and P2. In this case, the relay device uses the RX beam corresponding to Q1 to receive the uplink signal and the TX beam corresponding to P2 to transmit the downlink signal. Alternatively, the network-side device is also configured so that if the relay device does not receive beam indication information, it uses the TX beam labeled P1 to transmit the downlink signal and the RX beam labeled Q1 to receive the uplink signal.

[0148] In this embodiment, the relay device is not limited to a repeater, but can also be a RIS.

[0149] like Figure 7 As shown in the figure, a transmission processing method according to an embodiment of this application includes:

[0150] Step 701: The relay device receives beam indication information;

[0151] The beam indication information is used to indicate the transmission beam used by the relay device to transmit one or a group of first resources to the remote terminal; the transmission beam includes a transmit beam and / or a receive beam, and the first resource includes time domain resources and / or frequency domain resources.

[0152] When a beam indication message is sent by a network-side device, the relay device receives the beam indication message to know the transmission beam used by the relay device and the remote terminal for transmitting one or a group of first resources. Subsequently, for the transmission on the one or a group of first resources, the indicated transmission beam is used to realize the network side's control over the transmission between the relay device and the remote terminal, ensuring higher transmission quality.

[0153] After step 701, the relay device transmits on one or a group of first resources using the transmission beam indicated by the beam indication information.

[0154] Optionally, the beam indication information is indicated in at least one of the following ways:

[0155] Semi-static indication;

[0156] Dynamic indicators.

[0157] Optionally, the transmission beam is a fixed beam or a variable beam.

[0158] Optionally, if the network-side device indicates, through a semi-static method, that the transmission beam used by the first resource is a target fixed beam or a variable beam,

[0159] When the transmission beam is the target fixed beam, the network-side device indicates the beam information corresponding to the target fixed beam in a semi-static manner.

[0160] And / or, when the transmission beam is a variable beam, the network-side device sends beam indication information corresponding to the first resource in a dynamic indication manner.

[0161] Optionally, the dynamic indication can be implemented in the following ways:

[0162] The network-side device transmits a first DCI including the beam indication information;

[0163] Wherein, the first DCI is a specific DCI used for beam indication;

[0164] The specific DCI includes at least one of the following:

[0165] DCI in a specific format;

[0166] DCI corresponding to a specific wireless network temporary identifier RNTI;

[0167] DCI corresponding to a specific control resource set CORESET;

[0168] DCI corresponding to a specific search space SS.

[0169] Optionally, the specific DCI is a group common DCI, and the group common DCI is pre-configured with a target domain for carrying the beam indication information.

[0170] Optionally, the beam indication information includes a first identifier, which identifies one or a group of transmission beams, the one or a group of transmission beams being mapped to one or a group of first resources.
