[0021] Figure 1A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. The wireless communication system includes a terminal 11 and a network side device 12. Among them, the terminal 11 can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE) and other terminal side devices, and the wearable device includes: a bracelet, a headset, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

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.

[0022] When describing the embodiments of the present application, some concepts used in the following description are first explained.

[0023] V2X: The Long Term Evolution (LTE) system supports sidelink transmission, that is, data transmission between terminals directly on the physical layer. LTE sidelink is based on broadcast communication. Although it can be used to support basic safety communications of V2X, it is not suitable for other more advanced V2X services. The 5G NR system will support more advanced sidelink transmission designs, such as unicast, multicast or groupcast, so as to support a more comprehensive range of business types.

[0024] The LTE system has supported sidelink since the 12th release, which is used for direct data transmission between end-user devices without going through network equipment. LTE sidelink is designed for specific public safety matters (such as emergency communications in disaster sites such as fire sites or earthquakes), or vehicle-to-vehicle communications. Vehicle-to-vehicle communications include various services, such as basic safety communications, advanced (automatic) driving, platooning, sensor expansion, etc. Since LTE sidelink only supports broadcast communications, it is mainly used for basic safety communications. Other advanced V2X services with strict Quality of Service (QoS) requirements in terms of latency, reliability, etc. will be supported through NR sidelink.

[0025] NR R16 V2X supports vehicle to vehicle (V2V) communication. In R17, PUE needs to be supported, and pedestrian to vehicle (P2V) communication is considered. Vehicle to pedestrian (V2P) and pedestrian to pedestrian (P2P) communication can also be considered.

[0026] LTE PUE: Some PUEs in LTE PUE do not support the reception of SL information, because some PUEs have only one receive (Receive, RX) chain, and PUE needs to receive downlink (Downlink, DL) information. Some PUEs support the reception of SL information. If the PUE does not support the reception of SL information, the PUE can only select resources based on the random selection mode. If the PUE supports the reception of information, it can use the partial detection mode or the random selection mode to select resources according to the configuration information.

[0027] LTE PUE supports two resource selection modes, one is random selection mode, and the other is resource selection based on partial detection results. Which resource selection mode to choose can be a parameter configured by the high-level layer. When the Radio Resource Control (RRC) is configured to support two modes of resource selection, the PUE implements the decision of which resource selection method to use. In LTE, in random selection mode, the PUE will not receive information on the SL, that is, it will not perform operations such as sidelink control information (SCI) demodulation and reference signal received power (RSRP) measurement to detect resource exclusion, but will randomly select resources in the selection window according to certain rules (such as radio frequency (RF) restrictions, etc.). In LTE, it is believed that the PUE does not necessarily contain two downlink RX chains, that is, it is believed that the PUE may not be able to simultaneously receive the DL signal sent by the base station and the SL signal sent by the VUE. So it is possible that the PUE does not support detection.

[0028] R16 Sidelink Physical Sidelink Feedback Channel (PSFCH):

[0029] In order to carry the Acknowledgement (ACK) / Negative Acknowledgement (NACK) feedback information on the SL, NR V2X supports a new SL channel, namely PSFCH. The PSFCH channel has a period of N (N=1 / 2 / 4) in the time domain, where N means that every N time slots contain PSFCH. When N=0, it means that PSFCH is not configured in this resource pool.

[0030] UE can use feedback-based data transmission in unicast or multicast transmission. Among them, RRC can configure whether PSFCH resources are configured in the resource pool, and SCI indicates whether the transmission of the physical sidelink shared channel (PSSCH) scheduled by the SCI requires feedback. If the indication is that the hybrid automatic repeat request (HARQ) is enabled, the receiving end needs to send feedback information on the corresponding PSFCH resource; otherwise, it does not send. For the device sending data, if PSFCH is enabled, it means receiving feedback information on the corresponding PSFCH resource, otherwise, no feedback information is received.

[0031] R16 sidelink multicast type:

[0032] Multicast option 1: In the same group, the receiving UE only sends NACK to the sending end; different UEs send feedback information on the same resources for the same data.

[0033] Multicast option 2: The receiving end sends NACK / ACK to the sending end. Different UEs select different resources for transmission.

[0034] The information processing method provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0035] like Figure 2 As shown, an embodiment of the present application provides an information processing method, which is applied to a terminal, including:

[0036] Step 201: Select resources according to the information processing capability of the terminal or the type of the terminal; and / or process sidelink transmission according to the information processing capability of the terminal or the type of the terminal.

[0037] For different information processing capabilities or different terminal types, the terminal may have different choices for resources or resource pools. The information processing capability may be the processing capability of SL information and the processing capability of Uu port data; the SL information may include sidelink feedback information, sidelink data information, and sidelink control information; the terminal type may include: PUE, VUE. When selecting resources, you can select according to the information processing capability of the terminal, for example, select resources based on whether the terminal supports the reception of SL information, or select according to the type of terminal, for example, configure different resource selection methods when the terminal is a PUE and when the terminal is a VUE.

[0038] For different terminal information processing capabilities or different terminal types, the terminal may have different processing methods for unicast and multicast. In this embodiment, the processing of sidelink transmission may include establishing, processing or managing sidelink transmission, and configuring different sidelink transmission methods for different information processing capabilities of the terminal or different terminal types, for example: defining the connection establishment conditions for unicast or the processing method for multicast according to whether the terminal supports the reception of SL information, or configuring different sidelink transmission methods when the terminal is a PUE and when the terminal is a VUE, which can improve the resource utilization of the sending terminal, reduce the sending overhead, and achieve the purpose of power saving.

[0039] In the embodiments of the present application, resource selection is performed according to the information processing capability of the terminal or the type of the terminal, and / or sidelink transmission is processed. Different resource selection methods and sidelink transmission methods can be defined for different information processing capabilities or types of the terminal, thereby improving the resource utilization of the sending terminal, thereby improving the transmission efficiency of the sending terminal, improving the spectrum utilization of the system, and reducing the terminal energy consumption.

[0040] Specifically, the information processing capability of the terminal may include one of the following:

[0041] a) Receiving sidelink channels is not supported; the sidelink channels may include: sidelink feedback channel, sidelink shared channel, sidelink control channel, etc. The sidelink feedback channel is PSFCH, the sidelink control channel is physical sidelink control channel (Physical Sidelink Control Channel, PSCCH), and the sidelink shared channel is PSSCH.

[0042] It should be noted that the non-support for receiving the sidelink channel may also be non-support for receiving the sidelink information; the terminal under this capability does not support receiving SL information, but supports receiving Uu port information; the sidelink information may include: sidelink feedback information, sidelink data information, sidelink control information, synchronization information, etc. The sidelink data information may be carried on the PSSCH, and the sidelink control information may be carried on the PSCCH and / or carried on the PSSCH.

[0043] b) Supporting the reception of side link feedback information, but not supporting the reception of side link data information and side link control information; for example: only supporting the reception of side link feedback information, but not supporting the reception of side link data information and side link control information.

[0044] c) Supports receiving the sidelink feedback channel, but does not support receiving the sidelink control channel and the sidelink shared channel; for example: only supports receiving PSFCH, but does not support receiving PSCCH and PSSCH.

[0045] d) supporting the reception of sidelink data information, sidelink control information and sidelink feedback information;

[0046] e) Support reception of sidelink control channel, sidelink shared channel and sidelink feedback channel; that is, support reception of PSFCH, PSCCH and PSSCH.

[0047] f) Supports reception of sidelink feedback channel and sidelink control channel, but does not support reception of sidelink shared channel; that is, supports reception of PSFCH and PSCCH, but does not support reception of PSSCH.

[0048] g) Supporting simultaneous processing of Uu port information and PC5 port information; wherein the PC5 port information includes: side link feedback information, side link data information and side link control information; wherein the Uu port information includes: uplink (Up Link, UL) and downlink (Down Link, DL) transmission information, and the Uu port is the transmission interface between the terminal and the base station; the PC5 port information may be SL information, and the PC5 port is the transmission interface between Sidelink terminals.

[0049] h) Simultaneous processing of Uu port information and PC5 port information is not supported; when the terminal does not support simultaneous processing of Uu port information and PC5 port information, the terminal has only one RX chain and can receive Uu port information or side link information at a certain time.

[0050] i) supporting sending of a side link feedback channel; it should be noted that the supporting sending of a side link feedback channel may also be supporting sending of side link feedback information.

[0051] j) Not supporting sending of the sidelink feedback channel. It should be noted that not supporting sending of the sidelink feedback channel may also mean not supporting sending of sidelink feedback information.

[0052] For the above items i to j, in order to define the capability of the terminal according to whether the terminal supports sending sidelink feedback information or PSFCH, it can be further distinguished as supporting the sending of sidelink feedback information or PSFCH, and not supporting the sending of sidelink feedback information or PSFCH based on any one of items a to h.

[0053] For example, the capability of item c) can be further defined as:

[0054] (1) Supporting the reception of sidelink feedback information, but not supporting the reception of sidelink data information and sidelink control information, and not supporting the transmission of sidelink feedback information or the transmission of sidelink feedback channels;

[0055] (2) Supporting receiving sidelink feedback information, but not supporting receiving sidelink data information and sidelink control information, and supporting sending sidelink feedback information or supporting sending a sidelink feedback channel.

[0056] For example, the capability of item e) can be further defined as:

[0057] (1) Supporting the reception of sidelink data information, sidelink control information and sidelink feedback information, but not supporting the transmission of sidelink feedback information or the transmission of a sidelink feedback channel;

[0058] (2) Supporting the reception of sidelink data information, sidelink control information and sidelink feedback information, supporting the sending of sidelink feedback information or supporting the sending of a sidelink feedback channel.

[0059] It should be noted that when the protocol predefines the information processing capability of the terminal, one or more of the above capabilities a to j may be defined as optional items of the terminal capability, and the information processing capability actually possessed by the terminal is one of the above items.

[0060] Optionally, when the terminal performs resource selection, the resource selection may be performed according to the information processing capability of the terminal. Specifically, the resource selection according to the information processing capability of the terminal includes at least one of the following:

[0061] 1) Select a resource pool or resource according to a rule corresponding to the information processing capability. The rule corresponding to the information processing capability may be a rule predefined by a protocol, or may be a rule configured or preconfigured by a terminal or a network, for example, a rule corresponding to a preconfigured first information processing capability is a first resource selection mode, and a rule corresponding to a second information processing capability is a second resource selection mode. The resource or resource pool selected by the terminal is a resource or resource pool corresponding to its information processing.

[0062] 2) According to the information processing capability, select a resource pool or resource corresponding to the information processing capability. Different resources or resource pools are provided for different information processing capabilities of the terminal, and the resource or resource pool corresponding to the information processing capability can be selected according to the information processing capability of the terminal; for example: a terminal with a first information processing capability corresponds to a first resource, and a terminal with a second information processing capability corresponds to a second resource. The resource pool or resource corresponding to the information processing capability can be a rule predefined by the protocol, or a rule configured or preconfigured by the terminal or network. In this embodiment, the resource or resource pool selected by the terminal corresponds to the information processing capability of the terminal, and different information processing capabilities correspond to different resources or resource pools.

[0063] 3) According to the resource selection mode of the terminal, select a resource pool or resource corresponding to the information processing capability. The resource selection mode may include a random selection mode and a partial detection mode, and different resource selection modes correspond to different information processing capabilities of the terminal. The resource or resource pool selected by the terminal corresponds to the information processing capability of the terminal, and different information processing capabilities correspond to different resources or resource pools. The resource pool or resource corresponding to the information processing capability may be a rule predefined by the protocol, or a rule configured or preconfigured by the terminal or network.

[0064] Optionally, when the terminal performs resource selection, the resource selection may be performed according to the type of the terminal. Specifically, the resource selection according to the type of the terminal includes at least one of the following:

[0065] 1) Select a resource pool or resource according to a rule corresponding to the type of the terminal. The rule corresponding to the type of the terminal may be a rule predefined by a protocol, or may be a rule configured or preconfigured by the terminal or network, for example, a resource selection rule for a preconfigured PUE is a first resource selection mode, and a resource selection rule for a preconfigured VUE is a second resource selection mode.

[0066] 2) According to the type of the terminal, select a resource pool or resource corresponding to the type of the terminal. Different types of terminals have different resources or resource pools, and the resource or resource pool corresponding to the type of the terminal can be selected according to the type of the terminal; for example, PUE corresponds to the first resource, and VUE corresponds to the second resource. The resource pool or resource corresponding to the type of the terminal can be a rule predefined by the protocol, or a rule configured or preconfigured by the terminal or network.

[0067] 3) According to the resource selection mode of the terminal, select a resource pool or resource corresponding to the type of the terminal. The resource selection mode may include a random selection mode and a partial detection mode, and different resource selection modes correspond to different terminal types. The resource pool or resource corresponding to the type of the terminal may be a rule predefined by the protocol, or may be a rule configured or preconfigured by the terminal or network.

[0068] In this embodiment, the resource or resource pool selected by the terminal corresponds to the type of the terminal, and different types of terminals correspond to different resources or resource pools.

[0069] Furthermore, the selected resource pool satisfies at least one of the following conditions:

[0070] A: a resource pool that does not contain feedback resources; specifically, the selected resource pool does not contain feedback resources, including one of the following:

[0071] a1: the resource pool does not support PSFCH configuration, that is, the resource pool selected by the terminal does not support PSFCH configuration;

[0072] a2: The period configuration of PSFCH in the resource pool is zero, that is, the period configuration of PSFCH in the resource pool selected by the terminal is zero; for example: if the UE does not support the reception of PSSCH / PSSCH and does not support the reception of PSFCH, the period configuration of PSFCH in the resource pool where the UE is located is 0.

[0073] a3: PSFCH is not configured in the resource pool, that is, the terminal does not select the resource pool configured with PSFCH.

[0074] It should be noted that this embodiment mainly considers PUEs that do not have the ability to receive SL information, and selects a resource pool without feedback resources. PUEs can make the most of time domain resources. For the transmission of the same transport block (TB), the code rate of PUE transmission can be reduced, and the reliability of transmission can be improved. In addition, when there are more time domain resources, a larger transport block set (TBS) of TBs can be transmitted, which can be applicable to terminals that do not have the ability to receive SL (including PUEs that do not receive PSFCH), such as: UEs that do not support receiving sidelink feedback information, sidelink data information, and sidelink control information, or UEs that do not support simultaneous processing of Uu port information and sidelink information.

[0075] B: Physical sidelink feedback channel PSFCH is not enabled. Specifically, the physical sidelink feedback channel PSFCH is not enabled, which can be indicated by at least one of the following ways;

[0076] b1: The radio resource control RRC indicates that PSFCH is disabled; for example, if the UE does not support the reception of PSSCH / PSSCH, does not support the reception of PSFCH, when the UE sends information, the PSFCH indication in the RRC is disabled; or, for example, if the terminal is a PUE, the RRC can be configured as a preset value, and the preset value implicitly indicates that PSFCH is disabled.

[0077] b2: Side link control information SCI indicates that PSFCH is not enabled; for example: if the UE does not support the reception of PSSCH / PSSCH, does not support the reception of PSFCH, when the UE sends information, the PSFCH indication in the SCI is disabled; or, for example: if the terminal is a PUE, the SCI can be configured as a preset value, and the preset value implicitly indicates that PSFCH is not enabled.

[0078] b3: Downlink Control Information (DCI) indicates no feedback; for example, the mode-1 DCI indicates no feedback, indicating that the PSFCH on the SL is not enabled;

[0079] b4: All or part of the DCI domain values ​​are configured as preset values; for example, a special code point in a special threshold of DCI indicates that PSFCH is not enabled;

[0080] b5: All or part of the SCI domain values ​​are configured as preset values; for example, a special code point in a special threshold of the SCI indicates that PSFCH is not enabled;

[0081] b6: DCI is not configured with indication information related to HARQ and / or Physical Uplink Control Channel (PUCCH); when DCI is not configured with indication information related to HARQ and PUCCH, it indicates that PSFCH is not enabled; wherein, the indication information related to PUCCH may be feedback information.

[0082] b7: The HARQ and / or PUCCH related indication field in the DCI or SCI is in the reserved state; when the HARQ and / or PUCCH related indication field is in the reserved state, it means that PSFCH is not enabled;

[0083] b8: The HARQ and / or PUCCH related indication field in the DCI or SCI indicates an invalid value; when the HARQ and / or PUCCH related indication field indicates an invalid value, it means that PSFCH is not enabled;

[0084] b9: a preset code point in the DCI or SCI indicates that PSFCH is not enabled; for example, a special code point (such as an invalid code point) in the DCI or SCI indicates that the DCI or SCI is enabled;

[0085] b10: The enable status of PSFCH is indicated by bit information in DCI or SCI; for example, 1 bit information is used to indicate that PSFCH is disabled.

[0086] It should be noted that the above method of indicating that PSFCH is not enabled through indication information can be applied to UEs that do not have the ability to receive SL information, including UEs that do not receive PSFCH, for example: UEs that do not support receiving sidelink feedback information, sidelink data information, and sidelink control information, or UEs that do not support simultaneous processing of Uu port information and sidelink information. The resource pool selected by the terminal in this embodiment may be a resource pool that is configured with PSFCH or a resource pool that is not configured with PSFCH, but when scheduling UE data, the reception or transmission of PSFCH is not enabled.

[0087] The above-mentioned method of indicating that PSFCH is disabled through signaling can be an explicit indication by signaling, or an implicit indication by signaling. For example: SCI signaling indicates that PSFCH is disabled, or SCI implicitly indicates that PSFCH is disabled when it is a preset value; implicitly indicates that PSFCH is disabled when some or all thresholds in DCI or SCI are preset values; preset code points or bit information in DCI or SCI implicitly indicates that PSFCH is disabled. When the terminal receives at least one of the above-mentioned indication information, it is considered that PSFCH is disabled, and the terminal does not feedback. For example: when some thresholds in the DCI received by the terminal are preset values, it is considered that PSFCH is disabled, and the transmission is not fed back; when the HARQ and / or PUCCH related indication fields in the DCI or SCI received by the terminal are in a reserved state, it is considered that PSFCH is disabled, and the transmission is not fed back. That is, any one or more of the above-mentioned methods can indicate that PSFCH is disabled explicitly or implicitly.

[0088] Optionally, the resources selected according to the information processing capability of the terminal or according to the type of the terminal are: resources that do not include PSFCH. The resources that do not include PSFCH may be non-PSFCH resource locations, for example: when the terminal does not support receiving SL information, the UE sends information in non-PSFCH resources. It should be noted that the resource pool selected by the terminal in this embodiment may be a resource pool that is configured with or not configured with PSFCH, for example: the resource pool selected by the terminal is a resource pool that does not include PSFCH resources; or, the terminal selects a resource pool that is configured with PSFCH, but the selected resources do not include PSFCH resources.

[0089] Further, when the terminal is a first type terminal, or the terminal does not support receiving sidelink feedback information or a sidelink feedback channel, or the resource selection mode of the terminal is a random selection mode, the selected resource pool does not include feedback resources.

[0090] Among them, the first type of terminal can be a PUE, that is, a UE with low complexity or low power consumption or low processing capability, that is, when the terminal is a PUE, the resources selected by the PUE do not include feedback resources; or, when the terminal does not support receiving PSFCH or side-link feedback information, the resources selected by the terminal do not include feedback resources; or, when the resource selection mode of the terminal is a random selection mode, the resources selected by the terminal do not include feedback resources.

[0091] Optionally, when the terminal supports receiving PSFCH or sidelink feedback information, does not support receiving sidelink control information or PSCCH, and does not support receiving sidelink data information or PSSCH, the terminal may select a resource pool that does not contain feedback resources, or select a resource pool that does not enable PSFCH, or select resources that do not contain PSFCH.

[0092] When the terminal supports receiving sidelink data information, sidelink control information and sidelink feedback information, or the terminal supports receiving a sidelink control channel, a sidelink shared channel and a sidelink feedback channel, or the resource selection mode of the terminal is a partial detection mode, the terminal may select a resource pool that does not include feedback resources, or select a resource pool in which PSFCH is not enabled, or select resources that do not include PSFCH.

[0093] The resource pool selected by the terminal may be a sending and / or receiving resource pool.

[0094] Specifically, when selecting resources according to the information processing capability of the terminal or the type of the terminal, the terminal performs a target operation; the target operation includes at least one of the following:

[0095] a) The terminal ignores the transmission type indication information; for example, the terminal ignores the transmission type (cast type) indication (including the cast type indication field). The transmission type indication information may be unicast, multicast or broadcast type indication information.

[0096] b) The terminal ignores the hybrid automatic repeat request HARQ enable or disable indication information; the terminal ignores part or all of the feedback-related indication information, such as: HARQ enable (enable) or disable (disable) indication information, the HARQ enablea / disable indication is invalid, and it is considered that PSFCH is not enabled.

[0097] c) The terminal ignores the configuration information of the PSFCH frequency domain resources; the terminal ignores the feedback-related indication information, such as: the configuration information of the PSFCH frequency domain resources, and PSFCH is not enabled.

[0098] The sidelink transmission mode is different for different information processing capabilities of the terminal or different terminal types. The processing, management or establishment of the terminal transmission mode is related to the terminal capability or terminal type. Specifically, the processing of the sidelink transmission includes:

[0099] In a case where the terminal is a first type terminal, or the terminal supports receiving sidelink feedback information or a sidelink feedback channel, unicast transmission is established or multicast transmission is established.

[0100] The first type of terminal may be a PUE, i.e., a UE with low complexity, low power consumption, or low processing capability. In this embodiment, when the terminal is a PUE, or the terminal supports receiving sidelink feedback information / PSFCH, unicast transmission or multicast transmission is allowed to be established. The multicast transmission may be a connection-based multicast transmission.

[0101] Optionally, when establishing unicast transmission or multicast transmission, if the terminal supports receiving a sidelink feedback channel or sidelink feedback information, the unicast connection or multicast connection is successfully established when the terminal receives at least one positive acknowledgment ACK information. For example, when the terminal receives one ACK information, or the terminal receives multiple ACK information, or the terminal receives multiple consecutive ACK information, or the terminal sends a connection establishment request but does not receive a NACK, it is considered that the unicast connection or multicast connection is successfully established, or the RRC connection is successfully established.

[0102] Specifically, when processing sidelink transmission, the terminal supporting the reception of a sidelink feedback channel or sidelink feedback information may be: a terminal supporting the reception of sidelink feedback information but not supporting the reception of sidelink data information and sidelink control information; or, a terminal supporting the reception of a sidelink feedback channel but not supporting the reception of a sidelink control channel and a sidelink shared channel; or, a terminal supporting the reception of sidelink data information, sidelink control information and sidelink feedback information; or, a terminal supporting the reception of a sidelink control channel, a sidelink shared channel and a sidelink feedback channel; or, a terminal supporting the simultaneous processing of Uu port information and sidelink information.

[0103] Optionally, the processing of the sidelink transmission also includes: when the terminal is a first type terminal, or the terminal does not support receiving sidelink information or a sidelink channel, prohibiting the establishment of unicast transmission, or the terminal ignoring the unicast connection establishment message.

[0104] In this embodiment, the first type of terminal may be a PUE, i.e., a UE with low complexity, low power consumption, or low processing capability. In this embodiment, the terminal does not support receiving sidelink information may be: the terminal does not support receiving sidelink feedback information, sidelink data information, and sidelink control information, or the terminal supports receiving sidelink feedback information but does not support receiving sidelink data information and sidelink control information, or the terminal does not support simultaneous processing of Uu port information and sidelink information; the terminal does not support receiving sidelink channels may include: the terminal does not support receiving sidelink feedback channels, sidelink control channels, and sidelink shared channels, or the terminal supports receiving sidelink feedback channels but does not support receiving sidelink control channels and sidelink shared channels. The prohibition of establishing unicast transmission may include the inability to establish / rebuild / modify / release an RRC connection.

[0105] Optionally, when the terminal is a first type terminal or the terminal does not support receiving sidelink information or a sidelink channel, the terminal does not desire to establish unicast transmission.

[0106] For different information processing capabilities of the terminal or different terminal types, the multicast transmission is processed differently. Specifically, for multicast transmission, when the terminal capability indicates that the terminal supports receiving sidelink feedback information or a sidelink feedback channel, the terminal satisfies at least one of the following:

[0107] 1) The sidelink control information SCI of the terminal adopts the SCI format in which the hybrid automatic repeat request response HARQ-ACK information only includes the negative response NACK. The SCI may be a second-level SCI, which is transmitted in the PSSCH, for example, the second-level SCI of the UE adopts the SCI format (such as format 2-B) in which the HARQ-ACK information only includes NACK.

[0108] 2) The second level SCI of the terminal adopts SCI format 2-B;

[0109] 3) The number of sidelink feedback information that the terminal supports receiving is less than or equal to N, where N is a capacity value that can be carried, which can be a value predefined by the protocol, preconfigured by the terminal or the network, or configured;

[0110] 4) The number of members in the group that the terminal supports multicast transmission is less than or equal to M, where M is a capacity value that can be carried and can be a value predefined by the protocol, preconfigured or configured by the terminal or network; the members in the group may include or exclude the group head.

[0111] 5) The terminal does not support multicast type 2 transmission, and the multicast type 2 is: groupcast option 2 type;

[0112] 6) The SCI of the terminal does not use the SCI format in which the HARQ-ACK information is NACK or ACK;

[0113] 7) The terminal only supports the transmission of multicast type 1, and the multicast type 1 is: groupcast option 1;

[0114] 8) The SCI indication information of the terminal does not indicate ACK, for example: the SCI of the terminal cannot indicate ACK.

[0115] For multicast transmission, when the terminal capability indicates that the terminal does not support receiving sidelink feedback information or a sidelink feedback channel, the terminal may meet at least one of the following conditions:

[0116] The terminal does not support multicast type 2 transmission, and the multicast type 2 is: groupcast option 2 type;

[0117] The SCI of the terminal does not use the SCI format in which the HARQ-ACK information is NACK or ACK;

[0118] The SCI indication information of the terminal does not indicate ACK, for example: the SCI of the terminal cannot indicate ACK.

[0119] The above conditions are for the terminal to meet during multicast transmission. Among them, the feedback of groupcast option 2 type is that each receiving UE feeds back ACK / NACK on the corresponding resource according to the predefined / preconfigured rules, and the feedback of groupcast option 1 type is that the receiving UE in a group feeds back NACK on the same resource.

[0120] It should be noted that the terminal does not support receiving sidelink feedback information or a sidelink feedback channel, which means that the information processing capability of the terminal at least does not support receiving sidelink feedback information or a sidelink feedback channel. For example, the information processing capability of the terminal is: does not support sidelink information, does not support simultaneous processing of Uu port information and PC5 port information, that is, when the information processing capability of the terminal at least does not support receiving sidelink feedback information or a sidelink feedback channel, the terminal can meet at least one of the above items.

[0121] Optionally, the method further includes: configuring a logical channel of the terminal, or configuring a logical channel mapping rule, or configuring a logical channel group according to the information processing capability of the terminal or the type of the terminal.

[0122] In this embodiment, the configuration of the logical channel of the terminal is related to the information processing capability of the terminal or the type of the terminal. Configuring the logical channel of the terminal or configuring the logical channel mapping rule according to the information processing capability of the terminal may include: defining / configuring a unique logical channel (logical channel, LCH) for low complexity / low power consumption UE / low processing capability UE, or LCH mapping rule, or logical channel group.

[0123] For example: when the terminal supports receiving SL information, a first logical channel or a first logical channel mapping rule is configured for the terminal; when the terminal does not support receiving SL information, a second logical channel or a second logical channel mapping rule is configured for the terminal.

[0124] The configuring of the logical channel of the terminal according to the type of the terminal, or configuring the logical channel mapping rule, may include: configuring a first logical channel or a first logical channel mapping rule for a first type of terminal, and configuring a second logical channel or a second logical channel mapping rule for a second type of terminal. For example: for communications with the same reliability requirements, if the terminal is a VUE, one LCH mapping may be configured and PSFCH may be enabled, but for a PUE (UE with low processing capability), another set of LCH mapping may be configured (for example: using N blind retransmissions because PSFCH is not supported).

[0125] Optionally, if the PUE supports the reception of information (including the reception of PSFCH / feedback information and the reception of PSSCH / data, and PSCCH / control information), the establishment of the unicast connection is determined according to the conditions in R16.

[0126] Optionally, the method further comprises: predefining, preconfiguring or configuring at least one of the following processing times:

[0127] Processing time of sidelink feedback information;

[0128] Processing time of the sidelink feedback channel;

[0129] Processing time of the physical sidelink shared channel PSSCH;

[0130] Processing time of the physical sidelink control channel PSCCH;

[0131] The processing time from the reception of the physical downlink control channel (PDCCH) to the transmission of the PSSCH; wherein the PSSCH refers to the PSSCH scheduled by the PDCCH; the processing time from the reception of the PSFCH to the transmission of the physical uplink control channel PUCCH.

[0132] At least one of the above-mentioned processing times is defined in the UE, and the processing time is related to the type of the UE and / or the subcarrier spacing (SCS). Specifically, predefining, preconfiguring or configuring the processing time includes: obtaining the processing time according to the type of the terminal and / or the subcarrier spacing SCS. It should be noted that for different terminal types, for example, PUE may require more processing time than VUE, so the processing time can be defined for PUE (low complexity / low power consumption UE / low processing capability UE).

[0133] The following describes a method for implementing resource selection and sidelink transmission processing according to the information processing capability of the terminal through a specific embodiment.

[0134] For example: when the terminal does not support PSSCH / PSCCH reception but supports PSFCH reception, the UE manages / establishes the sidelink connection according to predefined / configured rules and considers the connection reestablishment of RRC in unicast.

[0135] Method 1: The transmitting UE sends RRC connection establishment / reestablishment information to the receiving UE; if the receiving end demodulates successfully, it sends ACK; if the demodulation fails, it sends NACK; if the transmitting end receives ACK information, it considers that the connection is successfully established.

[0136] Method 2: The transmitting UE sends RRC connection establishment / reestablishment information to the receiving UE, wherein the information includes the transmitting end capability configuration information; the receiving end sends information according to the sent capability configuration information. If the demodulation finds that the transmitting end receiving capability only supports the reception of PSFCH on the SL, then: if the receiving end cannot comply with the configuration of the establishment / reestablishment message, the receiving end sends NACK information, otherwise, the receiving end sends ACK information; if the transmitting end receives ACK information, it considers that the connection establishment is successful, and if the transmitting end receives NACK information, it considers that the connection establishment fails.

[0137] For example: when the UE does not support the reception of PSSCH / PSCCH but supports the reception of PSFCH, if the UE sends data within the group (the group established by the upper layer), and the receiving end account (Identity document, ID) is the multicast ID (the group ID information determined by the upper layer), the second-level SCI sent by the UE uses the SCI format scheduling information that only contains NACK in the HARQ ACK information. Alternatively, the SCI format 2-B scheduling information is used. It should be noted that: this embodiment considers that only the transmission of groupcast option 1 is enabled.

[0138] In the embodiments of the present application, for different information processing capabilities of UE or different terminal types, the UE may have different selections of resources or resource pools, unicast processing methods, and multicast processing methods. If the UE supports feedback-based data transmission, the transmission efficiency of the transmitting UE can be improved, and the spectrum utilization of the system can be improved. If the terminal does not support data reception, on the basis of supporting PSFCH reception, the conditions for establishing a unicast connection can be defined, and establishing a unicast connection in the UE can improve the resource utilization of the transmitting UE.

[0139] In the embodiments of the present application, resource selection and / or sidelink transmission mode of the terminal are defined according to the information processing capability of the terminal or the type of the terminal, so as to improve the resource utilization of the sending terminal, thereby improving the transmission efficiency of the sending terminal, improving the spectrum utilization of the system, and reducing the energy consumption of the terminal.
