Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a beam processing method, device, terminal and network side equipment. Background Art

[0002] With the development of communication technology, some mobile communication systems (for example, New Radio (NR) system, etc.) support sidelink (SL) (or called side link, side link or edge link, etc.) transmission, that is, user equipment (UE) (or called terminal) can directly transmit information on the physical layer without going through network equipment.

[0051] For ease of understanding, some contents involved in the embodiments of the present application are described below:

[0052] 1. NR SL resource allocation or selection

[0053] There are two NR SL resource allocation methods, one is based on network-side equipment (e.g., base station) scheduling, namely mode 1 (mode 1), and the other is based on UE autonomous resource selection, namely mode 2 (mode 2). For mode 1, the sidelink resources used by the UE for data transmission are determined by the base station and notified to the sending UE (TX UE) through downlink signaling; for the resource allocation method selected by the UE autonomously, the UE selects available transmission resources from the pre-configured or configured resource pool. Before selecting resources, the UE first performs channel sensing, selects a resource set with less interference based on the channel sensing results, and then randomly selects resources for transmission from the resource set. For mode 2, the specific working method is as follows:

[0054] 1) After the resource selection is triggered, the TX UE first determines the resource selection window. The lower boundary of the resource selection window is T1 time after the resource selection is triggered, and the upper boundary of the resource selection is T2 time after the trigger, where T2 is the value selected by the UE within the packet delay budget (PDB) transmitted in its transport block (TB), and T2 is no earlier than T1.

[0055] 2) Before selecting resources, the UE needs to determine the candidate resource set (candidateresource set) for resource selection, and compare the reference signal receiving power (RSRP) measured on the resources in the resource selection window with the corresponding RSRP threshold (threshold). If the RSRP measured on a certain resource is higher than the RSRP threshold, the resource is excluded and cannot be included in the candidate resource set. After resource exclusion, the remaining resources in the resource selection window constitute the candidate resource set. The proportion of resources in the candidate resource set to the resources in the resource selection window must be no less than x%, where x% can be a value configured or pre-configured by the control node. If it is less than x%, the RSRP threshold needs to be increased according to the step value (3dB), and then the resource exclusion operation is performed until no less than x% of resources can be selected.

[0056] 3) After the candidate resource set is determined, the UE randomly selects a transmission resource from the candidate resource set. In addition, the UE can reserve transmission resources for the next transmission during the current transmission.

[0057] 2. Downlink (DL) / Uplink (UL) Beam Indication

[0058] In Release 15 (Rel-15) NR Uu, for a certain transceiver operation of the UE, its beam can be set independently. Among them, the transceiver beam of the Physical Downlink Control Channel (PDCCH) / Physical Uplink Control Channel (PUCCH) can be pre-configured, and the transceiver beam of PDSCH / PUSCH can be semi-statically configured or dynamically indicated by control information.

[0059] In the seventeenth version (Release 17, Rel-17) NR Uu, for the UE's transceiver operations within a certain agreed time end, the UE uses the indicated unified beam (Unified Beam) for transceiver.

[0060] The beam processing method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0061] See also Figure 2 , Figure 2 : is a flow chart of a beam processing method provided in an embodiment of the present application, comprising the following steps:

[0062] Step 201: The first terminal sends a first beam indication to the second terminal;

[0063] The first beam indication is used to indicate at least one of the following: at least one beam or at least one beam pair, at least one resource associated with a beam or at least one resource associated with a beam pair.

[0064] In this embodiment, one of the first terminal and the second terminal may be a transmitting terminal (TX UE), and the other may be a receiving terminal (RX UE). The at least one beam may be a receiving beam, or may be a transmitting beam, or may be a recommended receiving beam, or may be a recommended transmitting beam, etc. Each beam pair of the at least one beam pair includes a transmitting beam and a receiving beam. The resources associated with the at least one beam or beam pair may include at least one of time domain resources, frequency domain resources, resource pools, etc. It can be understood that this embodiment can support maintaining multiple pairs of beams between the first terminal and the second terminal, for example, Figure 3 As shown, multiple pairs of beams are maintained between the TX UE and the RX UE.

[0065] Exemplarily, the first terminal may send the first beam indication to the second terminal in a semi-static manner or in a periodic manner, for example, the first terminal sends the first beam indication to the second terminal through high-level signaling (for example, PC5 Radio Resource Control (RRC)); or, the first terminal may send the first beam indication to the second terminal in a dynamic or non-periodic manner, for example, the first terminal may send the first beam indication to the second terminal through dynamic signaling (for example, Media Access Control Control Element (MAC CE) or Sidelink Control Information (SCI)), etc.); or, the first terminal may send the first beam indication to the second terminal in a semi-persistent manner, for example, the first terminal may send the first beam indication to the second terminal through high-level signaling (for example, PC5 RRC), and the first terminal may further activate or deactivate the configured first beam indication through dynamic signaling (for example, MAC CE or SCI, etc.).

[0066] It should be noted that the number of the above-mentioned first beam indications can be one or at least two. For example, when the first terminal indicates a beam to the second terminal through high-level signaling, the first terminal can send a beam configuration to the second terminal through high-level signaling, and the beam configuration can include at least two first beam indications. Further, the first terminal can activate or deactivate the first beam indication in the above-mentioned beam configuration through dynamic signaling.

[0067] Exemplarily, after the first terminal sends the first beam indication to the second terminal, the first terminal and the second terminal can determine the transmission beam based on the first beam indication. Taking the first terminal as a transmitting terminal and the second terminal as a receiving terminal as an example, when the above-mentioned first beam indication indicates a beam pair, the first terminal can send data based on the transmitting beam in the beam pair, and accordingly, the second terminal can receive data based on the receiving beam in the beam pair; when the above-mentioned first beam indication indicates a receiving beam, the first terminal can determine the transmitting beam to send data based on the receiving beam indicated by the first beam indication, and accordingly, the second terminal can receive data based on the receiving beam indicated by the first beam indication; when the above-mentioned first beam indication indicates a resource, the first terminal can send data based on the transmitting beam associated with the resource indicated by the first beam indication, and the second terminal can receive data based on the receiving beam associated with the resource indicated by the first beam indication.

[0068] In the beam processing method provided in an embodiment of the present application, a first terminal sends a first beam indication to a second terminal; wherein the first beam indication is used to indicate at least one of the following: at least one beam or at least one beam pair, at least one beam-associated resource or at least one beam pair-associated resource. Since the above-mentioned first beam indication is sent by the first terminal to the second terminal, the first terminal and the second terminal can align the transmission beam based on the above-mentioned first beam indication during the SL transmission process, thereby improving the reliability of SL transmission between the first terminal and the second terminal.

[0069] Optionally, the first beam indication includes at least one of the following: beam information, resource information; the beam information is used to indicate at least one beam or at least one beam pair, and the resource information is used to indicate resources associated with at least one beam or at least one beam pair.

[0070] In this embodiment, the above-mentioned beam information may include but is not limited to at least one of the following: beam identification (beamID), beam pair identification (beam pair ID), resource identification (resource ID), transmission configuration indication (TransmissionConfiguration Indication, TCI), beam repetition (beam repetition), and beam sweeping (beamsweeping).

[0071] The above resource information may include but is not limited to: time domain resource information, frequency domain resource information, and resource pool information.

[0072] The above-mentioned time domain resource information may include but is not limited to at least one of the following:

[0073] Resource start position, for example, a slot or symbol offset, or an absolute time offset, or a slot offset and a symbol offset;

[0074] Resource length (Duration), for example, time slot length (Duration in slot), or, symbol length (Duration in symbol) or, absolute time length (Duration in absolute time);

[0075] Resource period (Period);

[0076] Refer to Subcarrier Spacing (SCS).

[0077] In some optional embodiments, the above-mentioned time domain resource information may be time domain resource information associated with beam information.

[0078] It should be noted that the above-mentioned time domain resource information may include the time domain resources corresponding to the following signals or channels: the symbol where the physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) is located; the symbol where the physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) is located; the symbol where the PSSCH and the automatic gain control (Automatic Gain Control, AGC) are located; the symbol where the standalone (Stand Alone, SA) channel state information reference signal (Channel State Information Reference Signal, CSI-RS) is located, the symbol where the SA CSI-RS and AGC are located, the symbol where the physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH) is located; the symbol where the PSFCH and AGC are located, etc.

[0079] The frequency domain resource information may include but is not limited to at least one of a carrier index, a bandwidth part index (BWP index), etc. The resource pool information may include, for example, a pool ID.

[0080] In some optional embodiments, each beam indication may include multiple time domain resource information and at least one of multiple beam information. For example, it may instruct the UE to use different beams to perform beam scanning operations on multiple time domain resources.

[0081] Optionally, the first beam indication further includes at least one of the following:

[0082] An indication mark of the first beam indication;

[0083] channel measurement information, where the channel measurement information is used for channel measurement between the first terminal and the second terminal;

[0084] location information of the first terminal;

[0085] Propagation type information.

[0086] In this embodiment, different beam indications may correspond to different indication identifiers (e.g., numbers), so that when there are multiple beam indications, different beam indications may be distinguished based on the indication identifier. Exemplarily, when the first terminal needs to update beam information, time domain resource information, etc. included in a beam indication, indication information may be sent to the second terminal, and the indication information may carry the indication identifier of the above beam indication, so that the second terminal determines the beam indication that needs to be updated based on the indication identifier.

[0087] The above-mentioned channel measurement information may include parameters reflecting channel quality and channel characteristics, such as RSRP value, Channel Quality Indicator (CQI) value, and recommended modulation and coding scheme (MCS) value. Exemplarily, for a beam indication sent by an RX UE, the RX UE may carry channel measurement information in the beam indication at the same time, and the channel measurement information may be measurement information for a certain transmit beam (TX beam), or measurement information for a beam pair of a certain TX beam and a receive beam (RX beam).

[0088] In some optional embodiments, the channel measurement information may reflect large-scale fading information, long-term RSRP / layer 3 (Layer 3, L3) filtered RSRP, and be used to assist the TX UE in performing operations such as power control.

[0089] In some optional embodiments, the channel measurement information may have a timeliness, which may be preset, or indicated by an indication signaling, or the end time of the timeliness is the receipt of an indication signaling for updating the channel measurement information. Optionally, the first beam indication also includes a valid time for the channel measurement information, during which the channel measurement information is valid.

[0090] The geographic location information of the first terminal, for example, a zone identifier (zone ID). Exemplarily, the beam information can be indicated together with the location information (for example, zone ID). The zone can indicate the approximate location of the TX UE, so the RX UE can infer the relative position and direction between the UEs (for example, northeast or southwest) based on its own zone and the zone of the TX UE. If the beam information is a global direction indication (for example, southeast, northwest), then the zone ID is combined with the beam information (for example, beam ID), and the RX UE can infer whether the transmission of the TX UE will send conflicts, interference, etc.

[0091] The above-mentioned propagation type (Cast type) information is used to indicate the propagation type, wherein the above-mentioned propagation type may include unicast, multicast or broadcast, etc. Exemplarily, different propagation types may have different beam indications. In some optional embodiments, the propagation type may be determined by the source ID or the destination ID targeted by the beam indication.

[0092] Optionally, the first beam indication is indicated in a semi-static manner or in a periodic manner.

[0093] Exemplarily, when the first beam indication is indicated in a semi-static manner or in a periodic manner, the first terminal may send the first beam indication to the second terminal via PC5 RRC.

[0094] Optionally, the method further comprises:

[0095] The first terminal sends a first indication signaling to the second terminal, where the first indication signaling includes a first indication identifier, which is used to indicate the release of the beam indication identified by the first indication identifier.

[0096] In this embodiment, the first terminal may send an indication signaling to the second terminal to release the beam indication, for example, by instructing the second terminal to release the beam indication through a specific indication field.

[0097] In this embodiment, since it supports distinguishing different beam indications through indicator identifiers and can release the beam indication identified by a certain indicator identifier through indication signaling, this is beneficial for the terminal to maintain multiple beams or multiple beam pairs at the same time to counteract rapidly changing channels in SL communication scenarios.

[0098] Optionally, the method may further include:

[0099] The first terminal sends an update indication signaling to the second terminal, where the update indication signaling includes first beam information, used to indicate that the first beam indication is updated according to the first beam information.

[0100] In this embodiment, the above-mentioned first beam information may include but is not limited to at least one of the following: beam identifier, beam pair identifier, resource identifier, TCI, beam repetition, and beam scanning.

[0101] Exemplarily, upon receiving the update indication signaling, the second terminal may update the beam information indicated by the first beam to the first beam information.

[0102] Optionally, the update indication signaling also includes a first target indication identifier, and the update indication signaling is used to indicate that the beam information of the beam indication identified by the first target indication identifier is updated to be the first beam information.

[0103] In this embodiment, the above-mentioned update indication signaling also includes a first target indication identifier, so that when there are multiple beam indications, the second terminal can determine the beam indication that needs to be updated based on the first target indication identifier.

[0104] Optionally, the method further comprises:

[0105] The first terminal sends a second indication signaling to the second terminal, where the second indication signaling is used to indicate activation or deactivation of the first beam indication.

[0106] Exemplarily, in the case where the first terminal sends a first beam indication to the second terminal in a semi-persistent manner, for example, the first terminal sends at least one first beam indication to the second terminal through high-layer signaling. In this case, the first terminal can activate or deactivate part or all of the at least one first beam indication through dynamic signaling, for example, activating or deactivating part or all of the at least one first beam indication indicated by PC5 RRC through MAC CE or SCI or physical layer signaling.

[0107] In some optional embodiments, the activation time of the above-mentioned first beam indication may be a preset time, or the activation time may last until the periodic beam indication corresponding to the indication identifier is deactivated, or the activation time may last until a new activation signaling takes effect.

[0108] Optionally, the second indication signaling includes a second indication identifier, and the second indication signaling is used to indicate activation or deactivation of a first beam indication corresponding to the second indication identifier.

[0109] In this embodiment, the second indication identifier may include at least one first beam indication identifier.

[0110] Exemplarily, when there are multiple first beam indications, the first terminal may carry a second indication identifier in the second indication signaling to indicate activation or deactivation of the first beam indication corresponding to the second indication identifier, thereby saving signaling overhead.

[0111] Optionally, the first beam indication is indicated in a dynamic manner or a non-periodic manner.

[0112] Exemplarily, the first terminal may send the first beam indication to the second terminal via MAC CE or SCI or physical layer signaling.

[0113] Optionally, the first beam indication includes a resource identifier, and the resource identified by the resource identifier is a resource configured by the first terminal through high-layer signaling;

[0114] or,

[0115] The first beam indication includes a third indication identifier, and the beam indication identified by the third indication identifier is the beam indication configured by the first terminal through high-layer signaling.

[0116] Exemplarily, resource information (e.g., time domain resource information) can be configured by high-level signaling (e.g., PC5-RRC), and dynamic signaling only carries the resource identifier (e.g., number); alternatively, time domain resource information and beam information can be configured by high-level signaling (e.g., PC5-RRC), and dynamic signaling only indicates the configuration identifier (e.g., number), that is, at least one beam indication is configured by high-level signaling, each beam indication includes time domain resource information and beam information, and dynamic signaling only carries the indication identifier of the beam indication, which can save the overhead of dynamic signaling.

[0117] In some optional embodiments, the dynamic signaling sent by the first terminal to the second terminal may include at least one of multiple time domain resource information and multiple beam information, so that the terminal can dynamically maintain multiple beam pairs at the same time, or the terminal can dynamically indicate operations such as beam sweeping.

[0118] Optionally, the method further comprises:

[0119] In a case where a beam conflict is detected between at least two beam indications at the same time, the first terminal determines a valid beam indication according to a priority relationship between the at least two beam indications.

[0120] In this embodiment, there is a beam conflict between at least two beam indications at the same time, which can be understood as the beams indicated by the at least two beam indications at different frequencies at the same time are different. For example, beam indication A indicates that the beam of carrier A1 of symbol A is beam a1, and beam indication B indicates that the beam of carrier B1 of symbol A is beam b1, wherein beam a1 and beam b1 are different beams.

[0121] The priority relationship between the above-mentioned at least two beam indications can, exemplarily, be predefined by a protocol, or can be determined by a control node, or can be determined based on the contents of the above-mentioned at least two beam indications, etc.

[0122] The effective beam indication is determined according to the priority relationship between the at least two beam indications. Exemplarily, the beam indication with the highest priority among the at least two beam indications that send beam conflicts can be determined as the effective beam indication.

[0123] Exemplarily, when a first terminal sends multiple beam indications to a second terminal, or when a first terminal sends multiple beam indications to multiple second terminals, if there is a beam conflict between the multiple beam indications, the first terminal can determine the effective beam indication based on the priority relationship between the multiple beam indications that cause the beam conflict.

[0124] Optionally, for the scenario where the first terminal sends multiple beam indications to the second terminal, the second terminal may be a physical device or multiple logical UEs corresponding to a physical device, for example, a logical UE corresponding to a unicast ID, a logical UE corresponding to a groupcast ID, or a logical UE corresponding to a broadcast ID. For the scenario where the first terminal sends multiple beam indications to multiple second terminals, the multiple second terminals may be understood as multiple logical UEs, and optionally, the multiple logical UEs may be multiple logical UEs corresponding to the same physical device.

[0125] Optionally, the priority of the beam indication indicated in a dynamic manner or a non-periodic manner is greater than the priority of the beam indication indicated in a semi-static manner or a periodic manner;

[0126] or,

[0127] The priority of the beam indication indicated in a semi-static manner or in a periodic manner is greater than the priority of the beam indication configured in a semi-persistent manner;

[0128] or,

[0129] The priority of the beam indication indicated in a dynamic manner or a non-periodic manner is greater than the priority of the beam indication configured in a semi-persistent manner.

[0130] In this embodiment, the beam indication configured in the semi-persistent manner may be a beam indication configured through high-layer signaling, such as PC5 RRC signaling.

[0131] Optionally, the priority relationship between the at least two beam indications is determined according to at least one of the following information:

[0132] priority indication information carried by at least one beam indication of the at least two beam indications;

[0133] an indication granularity of at least one beam indication of the at least two beam indications;

[0134] a sending time of at least one beam indication of the at least two beam indications;

[0135] At least one of the at least two beam indicators corresponds to a channel or a signal;

[0136] first information of a frequency domain resource corresponding to at least one beam indication of the at least two beam indications, the first information comprising at least one of a position, a sequence number and a type, the type comprising a reference frequency domain resource or a non-reference frequency domain resource;

[0137] At least one of the at least two beam indications corresponds to a propagation type.

[0138] In this embodiment, the priority indication information carried by the above-mentioned beam indication is used to indicate the priority of the beam indication. For example, the above-mentioned priority indication information may be a priority identifier.

[0139] For determining the priority relationship based on the priority indication information carried by the beam indication, in some optional embodiments, each beam indication of the at least two beam indications carries the priority indication information, so that the priority relationship between the at least two beam indications can be determined based on the priority indication information carried by each beam indication of the at least two beam indications. In some optional embodiments, if some of the multiple beam indications in which a beam conflict occurs carry a priority identifier and some do not carry a priority identifier, the priority of the beam indication carrying the priority identifier is higher than the priority of the beam indication not carrying the priority identifier. For example, if the beam indication of a periodic indication includes a priority identifier, the priority of the beam indication of the periodic indication is higher than the priority of the beam indication without a priority identifier. For the transmission of the reference signal (RS) of the radio link monitor (RLM), which has a higher priority, the beam indication corresponding to the RS of the RLM can carry a priority identifier.

[0140] For determining a priority relationship based on the indication granularity of the beam indication, for example, the priority of the beam indication with symbol as the indication granularity is higher than the priority of the beam indication with slot as the indication granularity, so as to prioritize the transmission of RS. In some optional embodiments, the priority relationship between the at least two beam indications may be determined according to the indication granularity of each of the at least two beam indications.

[0141] For determining the priority relationship based on the transmission time of the beam indication, for example, the priority of the beam indication with a later transmission time is higher than the priority of the beam indication with an earlier transmission time. Exemplarily, after the beam indication with a later transmission time takes effect, the UE adjusts the beam according to the beam indication. In some optional embodiments, the priority relationship between the at least two beam indications may be determined according to the transmission time of each of the at least two beam indications.

[0142] For determining the priority relationship based on the channel or signal corresponding to the beam indication, for example, the priority of each channel or signal can be agreed upon by agreement to protect the reception and transmission of important signals. Exemplarily, if a beam conflict occurs between the beam indication corresponding to CSI-RS and the beam indication corresponding to PSCCH / PSSCH, the beam indication corresponding to CSI-RS takes precedence; if a beam conflict occurs between the beam indication corresponding to CSI-RS and the beam indication corresponding to PSFCH, the beam indication corresponding to PSFCH takes precedence. In some optional embodiments, the priority relationship between the at least two beam indications can be determined based on the channel or signal corresponding to each of the at least two beam indications.

[0143] The priority relationship is determined based on the first information of the frequency domain resources corresponding to the beam indication, wherein the above-mentioned frequency domain resources may include but are not limited to a resource pool (pool), a carrier (carrier) or a BWP. The above-mentioned reference frequency domain resources, for example, a reference resource pool (reference pool), a reference carrier (reference carrier) or a reference BWP (reference BWP), and the above-mentioned non-reference frequency domain resources are relative to the reference frequency domain resources, that is, frequency domain resources different from the above-mentioned reference frequency domain resources. Exemplarily, the beam indication corresponding to the frequency resource with a smaller serial number has a higher priority, or the beam indication corresponding to the reference frequency domain resource has a higher priority than the non-reference frequency domain resource. In some optional embodiments, the priority relationship between the above-mentioned at least two beam indications can be determined based on the first information of the frequency domain resources corresponding to each of the at least two beam indications.

[0144] A priority relationship is determined for the propagation type corresponding to the beam indication, for example, the priority of the beam indication corresponding to unicast is higher than the priority of the beam indication corresponding to multicast, or the priority of the beam indication corresponding to multicast is higher than the priority of the beam indication corresponding to broadcast. In some optional embodiments, the priority relationship between the at least two beam indications may be determined according to the propagation type corresponding to each of the at least two beam indications.

[0145] Optionally, the priority of the second beam indication is greater than the priority of the third beam indication, wherein the second beam indication is a beam indication corresponding to a channel on the reserved resources or a signal on the reserved resources, and the third beam indication is a beam indication among the at least two beam indications except the second beam indication.

[0146] In this embodiment, when the priority relationship is determined according to the channel or signal corresponding to each beam indication of at least two beam indications, the priority of the beam indication corresponding to the channel or signal on the reserved resource is higher than the priority of the beam indication corresponding to other signals or channels. The beam indication corresponding to the channel or signal on the reserved resource may also be referred to as a beam indication corresponding to the real channel or signal transmission and reception.

[0147] In some optional embodiments, for beam conflicts of real channel or signal reception and transmission (i.e., channels or signals on reserved resources), the processing method may also include determining the priority of the beam indication according to the priority of the channel or signal, and sending at least one of a beam conflict indication, a resource reselection indication, and a retransmission indication to the other end.

[0148] Optionally, the method further comprises:

[0149] The first terminal receives conflict indication information or beam suggestion information from the second terminal;

[0150] or,

[0151] The first terminal sends conflict indication information or beam suggestion information to the second terminal;

[0152] The conflict indication information is used to indicate that there is a beam conflict between beam indications, and the beam recommendation information is used to indicate the recommended beam indication when there is a beam conflict between beam indications.

[0153] In one embodiment, when the second terminal detects that there is a beam conflict between at least two beam indications at the same time, the second terminal may send conflict indication information or beam recommendation information to the first terminal, and the first terminal may perform conflict processing based on the conflict indication information or the beam recommendation information. For example, the effective beam indication among the at least two indication beams with a beam conflict may be determined according to the conflict indication information, or the effective beam indication may be determined according to the beam recommendation information.

[0154] Exemplarily, when the second terminal receives multiple beam indications from multiple first terminals, the second terminal may send conflict indication information or beam suggestion information to the first terminal when detecting that there is a beam conflict between at least two beam indications at the same time. In this scenario, the multiple first terminals may be multiple logical UEs, and optionally, the multiple logical UEs may be multiple logical UEs corresponding to the same physical device.

[0155] In another embodiment, when the first terminal detects that there is a beam conflict between at least two beam indications at the same time, the first terminal may send conflict indication information or beam recommendation information to the second terminal, and the second terminal may perform conflict processing based on the conflict indication information or the beam recommendation information. For example, the effective beam indication of at least two indication beams with a beam conflict may be determined according to the conflict indication information, or the effective beam indication may be determined according to the beam recommendation information.

[0156] Optionally, the conflict indication information includes at least one of the following: an indication identifier of a fourth beam indication, a source identifier corresponding to the fourth beam indication, a destination identifier corresponding to the fourth beam indication, and a beam conflict flag; wherein the fourth beam indication is a beam indication in which a beam conflict occurs.

[0157] The source ID corresponding to the fourth beam indication is used to indicate the terminal sending the fourth beam indication, and the destination ID corresponding to the fourth beam indication is used to indicate the terminal receiving the fourth beam indication. The beam conflict flag is used to indicate that a beam conflict has occurred.

[0158] Optionally, the method further comprises:

[0159] When the first terminal detects that there is a beam conflict between a beam indication sent by the first terminal and a beam indication received by the first terminal, the first terminal determines that an effective beam indication is the beam indication sent by the first terminal, or the first terminal determines that the effective beam indication is the beam indication received by the first terminal.

[0160] Exemplarily, when there is a beam conflict between a beam indication sent by the first terminal and a beam indication received by the first terminal, the beam indication that takes effect by default may be the beam indication sent by the first terminal, or the beam indication that takes effect by default may be the beam indication received by the first terminal.

[0161] It should be noted that, for the scenario where a beam conflict occurs between multiple beam indications, from the perspective of the sending side of the beam indication, the sending terminal may be a logical UE or a physical UE (i.e., a physical device); however, the receiving terminal generally refers to a logical UE, or, when the sending terminal obtains multiple logical UE IDs corresponding to the receiving side (e.g., unicast ID, groupcast ID, broadcast ID, etc.), the receiving terminal may also be a physical UE corresponding to multiple logical UEs. From the perspective of the receiving side of the beam indication, the receiving terminal may be a logical UE or a physical UE; however, the sending terminal generally refers to a logical UE, or, when the receiving terminal obtains multiple logical UE IDs corresponding to the sending side (e.g., unicast ID, groupcast ID, broadcast ID, etc.), the sending terminal may also be a physical UE corresponding to multiple logical UEs.

[0162] It should also be noted that one of the beam indication sent by the transmitting terminal to the receiving terminal and the beam indication sent by the receiving terminal to the transmitting terminal is auxiliary information, and conflict handling of the auxiliary information can be implemented by the terminal.

[0163] Optionally, when the first terminal adopts the first resource allocation mode, the method further includes:

[0164] The first terminal sends part or all of the information of a fifth beam indication to a network side device, where the fifth beam indication includes at least one beam indication sent by the first terminal to the second terminal.

[0165] In this embodiment, the first resource allocation mode may refer to a resource allocation mode based on network-side device scheduling, that is, mode 1. The fifth beam indication may include part or all of the beam indications sent by the first terminal to the second terminal.

[0166] Optionally, the first terminal reports part or all of the information (e.g., time domain resource information, beam information) in the fifth beam indication to the network side device, so that the network side device schedules the transmission resources within the time domain resources indicated by the above time domain resource information for the first terminal. For example, when the base station schedules the transmission from TX UE to RX UE, the base station preferentially schedules the resources located on the time domain resources reported by TX UE. For another example, the base station determines the interference direction of the signal based on the beam direction of the beam indicated by the beam information reported by TX UE, and schedules the transmission resources of TX UE to other UEs according to the direction of the interference to achieve spatial division multiplexing.

[0167] Optionally, when the first terminal adopts the second resource allocation mode, the method further includes:

[0168] The first terminal determines a transmission resource according to a fifth beam indication, where the fifth beam indication includes at least one beam indication sent by the first terminal to the second terminal.

[0169] In this embodiment, the second resource allocation mode may refer to a resource allocation mode in which the terminal autonomously selects resources, that is, mode 2. The fifth beam indication may include part or all of the beam indications sent by the first terminal to the second terminal.

[0170] The above-mentioned first terminal determines the transmission resources according to the fifth beam indication. For example, the first terminal can determine the transmission resources based on the resources indicated by the fifth beam indication.

[0171] Optionally, the first terminal determines a transmission resource according to the fifth beam indication, including at least one of the following:

[0174] The media access control MAC layer of the first terminal preferentially selects transmission resources belonging to the time domain resources indicated by the fifth beam indication from the candidate resource set.

[0175] In this embodiment, the energy measurement value may include but is not limited to an RSRP value. The energy unit may be an energy unit corresponding to the unit of the energy measurement value. For example, if the energy measurement value is an RSRP value and its unit is DBm, the energy unit may also be DBm. At least one of M and N may be a value predetermined by the protocol, or a value indicated by the control node, or a value determined by the first terminal, etc.

After determining the candidate resource set, the first terminal may select a transmission resource from the candidate resource set.

[0179] Case 2: determining a set of alternative resources according to the fifth beam indication.

[0180] Exemplarily, when determining the resource selection window, the first terminal may determine an alternative resource set based on the resource selection window. For example, the time domain resources whose energy measurement values ​​in the resource selection window are greater than or equal to the threshold and belong to the time domain resources indicated by the fifth beam indication are added to the alternative resource set; or, the time domain resources other than the time domain resources indicated by the fifth beam indication in the resource selection window are excluded from being added to the alternative resource set; or, the first time domain resource among the time domain resources indicated by the fifth beam indication is added to the alternative resource set. After determining the alternative resource set, the first terminal may select a transmission resource from the alternative resource set.

[0193] In some optional embodiments, the above-mentioned beam validity confirmation information can be carried by independent signaling, for example, the TXUE sends a signaling carrying the beam indication, and the RX UE sends a signaling carrying the above-mentioned beam validity confirmation information.
