[0019] With the development of wireless multimedia services, people's demands for high data rates and user experience are increasing, which brings about higher requirements for the system capacity and coverage of traditional cellular networks. Meanwhile, application scenarios such as public safety, social networks, short-distance data sharing, and local advertising are gradually increasing people's demands for understanding and communicating with nearby people or things (proximity services). Traditional base station-centric cellular networks have obvious limitations in terms of high data rates and proximity service support. In the background of this demand, device-to-device (D2D) communication technology has emerged. The application of D2D technology can reduce the burden on cellular networks, reduce the battery power consumption of user equipment, increase data rates, and improve the robustness of network infrastructure, which meets the above-mentioned high data rate service and proximity service requirements. D2D technology is also known as proximity service (Proximity Service, ProSe), unidirectional / sidelink / throughlink (sidelink (SL)) communication. The interface between devices is a PC5 interface.

[0020] From the perspective of 5G standards, in the current New Radio (NR) sidelink communication system, there is no negotiation of data transmission time between the user equipment (UE) and the device. For a UE using NR sidelink mode 2 communication, the UE needs to continuously monitor the data reception channel to assist transmission resources. At the same time, the UE detection mechanism of the existing NR sidelink communication system cannot accurately obtain the communication conditions of the peer UE, and hidden terminals and exposed terminals are prone to occur. To address at least these technical issues, the UE can consider the use of auxiliary resources provided by other UE selection information (e.g., UE-to-UE cooperation).

[0021] For inter-UE coordination, there are two types of UEs, one is UE-B and the other is UE-A. In some embodiments, the UE that sends an explicit request for inter-UE coordination information can be UE-B, and the UE that receives the explicit request from UE-B and sends inter-UE coordination information to UE-B can be UE-A. In some other embodiments, UE-B is a UE that transmits a physical sidelink control channel (PSCCH) or a physical sidelink shared channel (PSSCH) with sidelink control information (SCI) indicating the reserved resource(s) used for its transmission, receives inter-UE coordination information from UE-A indicating predicted / potential resource contention(s) for the reserved resource(s) and uses it to decide resource reselection, and UE-A is a UE that detects predicted / potential resource contention(s) for the resource(s) indicated by UE-B's SCI and sends inter-UE coordination information to UE-B. Thus, in general, UE-A can provide assistance information for UE-B's data transmission.

[0022] To support a wider range of applications and services, sidelink-based relay communication has been proposed to extend coverage and improve network power consumption. For example, sidelink-based relay communication can be applied to indoor relay communication, smart farming, smart factories, and public safety services.

[0023] FIG. 1 illustrates a scenario in which sidelink-based relay communication is applied, including: 1) UE-Network Relay (Mode 1 shown in Figure 1): Mode 1 relay communication is designed for User Equipment (UE) (e.g., UE1 shown in Figure 1) in areas with weak or no coverage. Under such conditions, UE1 is enabled to communicate with the network (e.g., Base Station (BS) shown in Figure 1) via nearby UE2 covered by the network. As a result, the network coverage is extended and the network capacity is expanded. Please note that in this scenario, UE2 is called UE-Network Relay and UE1 is called Remote UE. 2) UE-to-UE Relay (Mode 2 shown in Fig. 1): During an emergency (e.g., earthquake), a cellular network may operate abnormally or the sidelink communication range of the network needs to be extended. Therefore, relay communication is designed to enable UEs to communicate with each other through relay UEs. As shown in Fig. 1, UE 3 communicates with UE 4 through UE 5 (or multiple relay UEs (not shown in Fig. 1)), which is called a UE-to-UE relay in this scenario.

[0024] For L2 UE-network relay, the adaptation layer is placed above both the control plane (CP) and user plane (UP) RLC sublayers at the Uu interface between the relay UE and the gNB. In addition, the adaptation layer is played over both the CP and UP RLC sublayers at the PC5 interface between the remote UE and the gNB. As known, the adaptation layer subheader is added to the relay traffic between the remote UE and the gNB. The adaptation layer may include the remote UE ID and the RB ID. Figure 2 shows the user plane (UP) protocol stack of the L2 UE-network relay. Uu SDAP / PDCP and RRC are terminated between the remote UE and the gNB, while RLC, MAC, and PHY are terminated within each link (e.g., the link between the remote UE and the UE-network relay UE, and the link between the UE-network relay UE and the gNB).

[0025] Sidelink control information (SCI) format 1-A includes the following: Priority-3 bits Frequency resource allocation - if the higher layer parameter sl-MaxNumPerReserve is configured with a value of 2,

[0026] The exemplary headings of the various sections below are used to facilitate understanding of the disclosed subject matter and are not intended to limit the scope of the claimed subject matter in any way. Thus, one or more features of one exemplary section may be combined with one or more features of another exemplary section. Furthermore, although 5G terminology is used for clarity of explanation, the technology disclosed herein is not limited to only 5G technology and may be used in wireless systems implementing other protocols.

[0027] Example 0

[0028] During the description of inter-UE coordination of sidelink communication, one technical solution is proposed to transmit assistance information via SCI or PSFCH-like signaling in the first or second stage. If SCI, or SCI in the first or second stage, or PSFCH-like signaling is used to transmit assistance information, is it necessary to develop a technique for determining the priority of signaling (e.g., signaling including SCI or PSFCH-like signaling) to perform intra-UE prioritization?

[0029] The procedure for inter-UE coordination may include the following operations. Step 1: UE-B may send UE-to-UE cooperation request signaling to UE-A, which may carry a support configuration, where the support configuration may include information used by UE-A to determine the support information. Step 2: UE-A may send a response signaling carrying the assistance information. In another case, UE-A may send a response signaling carrying the assistance information without receiving a request signaling.

[0030] Thus, this patent application describes at least four objectives: request signaling to convey assistance configuration, assistance configuration, response signaling to convey assistance information, and assistance information. The techniques described in this patent specification can be configured for any one of these four objectives.

[0031] 1. Techniques for performing intra-UE cooperation, e.g., techniques for determining signaling priorities 1. (a) UE-A obtains or determines a priority of the signaling carrying the assistance information or the assistance information: The techniques described below can be used to (1) set a priority for the signaling or (2) set a priority for the assistance information, in which case the priority of the signaling carrying the assistance information can be the same as the priority of the assistance information. A. The gNB may configure a priority for or for the signaling that carries or includes the assistance information. For example, the gNB may transmit a priority for the signaling that carries or includes the assistance information to the UE-A. In some embodiments, the priority may be allocated via SIB or RRC signaling or MAC CE or physical signaling or pre-configuration. B. UE-B may provide or transmit to UE-A a particular priority for or to the signaling carrying or including the assistance information. In some embodiments, the UE-B may provide the priority via RRC signaling or MAC CE or physical signaling. In some embodiments, the particular priority is the highest data priority at the UE-B when the UE-B sends the request signaling. C. The priority of the signaling conveying the assistance information or the assistance information is the priority of the signaling (eg, a request message) transmitted by UE-B to UE-A that triggers UE-A to provide the assistance information. 1.(b) UE-B determines the priority of signaling carrying the support configuration: A. The gNB may configure a priority for or to the signaling that carries or includes the support configuration. For example, the gNB may transmit a priority for the signaling that carries or includes the support configuration to the UE-B. In some embodiments, the priority may be allocated via SIB or RRC signaling or MAC CE or physical signaling or pre-configuration. B. The priority of the signaling that carries or includes the support configuration or the support configuration is the highest priority in UE-B.

[0032] In some embodiments, if a particular channel is designed or configured to carry assistance information (e.g., a PSFCH-like channel), the UE (e.g., UE-A) may be configured with a resource pool with or without a particular channel resource. In some other embodiments, if the UE (e.g., UE-B) wants to trigger a peer UE (e.g., UE-A) to provide assistance information, the UE (e.g., UE-B) needs to select a resource pool configured with a particular channel resource. In another embodiment, the UE-B can indicate certain resources (e.g., a list of one or more frequencies and / or a list of one or more time values) to the UE-A, so that the UE-A can transmit assistance information using the frequency and / or time resources from the list indicated by the UE-B.

[0033] For the SL-DRX design, the UE-B knows when to receive the assistance information, so when SL-DRX is configured, the UE-B should be in the active time. The time when the UE-B is trying to receive the assistance information is the active time of the UE-B.

[0034] 2. Techniques for indicating parameters for a UE to acquire transmission resources for signaling carrying assistance information or signaling carrying assistance configuration (e.g., in mode 1 or mode 2)

[0035] Any one or more of the following parameters may be indicated to the UE (e.g., UE-A) by the gNB or other UE: Priority configured for the signaling or for the assistance information or for the assistance configuration; a Hybrid Automatic Repeat Request (HARQ) retransmission number configured for the signaling or for the assistance information or for the assistance configuration, where the HARQ retransmission number indicates the number of times a HARQ retransmission is allowed to retransmit the signaling or assistance information; A packet delay budget (PDB) configured for the signaling, or for the aiding information, or for the aiding configuration; A packet error rate (PER) configured for the signaling or for the assistance information or for the assistance configuration, and / or · HARQ enable / disable attribute configured for signaling, for aiding information or for aiding configuration.

[0036] In some embodiments, if the signaling or assistance information or assistance configuration is HARQ-enabled, then if the UE (e.g., UE-A) wants to transmit the signaling or assistance information or assistance configuration using one or more resources from a resource pool, the UE (e.g., UE-B) should select a resource pool configured with PSFCH resources.

[0037] In some embodiments, the UE-B should send an indication to the gNB to indicate that the UE-B would like to receive assistance information over a specific resource, so that the gNB can configure a resource pool with the specific resource for the UE-B. Such an indication can be conveyed via RRC or MAC CE or PHY signaling.

[0038] In some embodiments, a scheduling request (SR) resource is configured for signaling or assistance information or assistance configuration.

[0039] In another embodiment, any of the above attributes of the signaling carrying the assistance information are the same as the assistance information. In another embodiment, any of the above attributes of the signaling carrying the assistance configuration are the same as the assistance configuration. For example, a priority is set for the assistance information, and the priority of the SCI carrying the assistance information is the priority of the assistance information.

[0040] In some embodiments, the UE selects a destination to transmit data to if the corresponding destination has signaling during the LCP carrying assistance information to transmit.

[0041] In some embodiments, a resource pool is configured with an attribute of whether the resource pool is permitted to transmit signaling conveying assistance information or configuration.

[0042] In some embodiments, the above configuration may be configured via RRC signaling, SIB, MAC CE, or physical signaling, PC5 RRC signaling, or peer UE.

[0043] Example 1

[0044] This example describes how the relay UE and remote UE consider the local identifier (ID) to be valid. In SL relay, the local ID is allocated by the remote UE or relay UE or gNB to identify the remote UE at the gNB or relay UE. However, the local ID is not always valid.

[0045] If one of the following conditions is met, the remote UE considers the local ID to be invalid, or the remote UE cannot use the local ID, or the remote UE should drop the stored local ID: The remote UE switches from an indirect link to a direct link. The physical cell ID or cell ID of the selected relay UE has changed. The physical cell ID or the cell ID of a connected relay UE has changed. A particular timer expires.

[0046] If one of the following conditions is met, the remote UE considers the local ID to be valid or may use the local ID: · The physical cell ID or cell ID of the selected relay UE has not changed. · The physical cell ID or cell ID of the connected relay UE has not changed.

[0047] A particular timer is started by the remote UE when any one of the following conditions is met: Transition to RRC_IDLE. Transition to RRC_INACTIVE. · Relay UE Uu RLF is detected. PC5 RLC is detected. Relay (re)selection is triggered.

[0048] A particular timer is stopped by the remote UE when any one of the following conditions is met: · The Cell ID or the Physical Cell ID of the selected relay UE has changed. The remote UE switches from an indirect link to a direct link. Transition to RRC_CONNECTED. An RRCSetup message is received. A RRCResume message is received. - A RRCR establishment message is received. An RRCSetupRequest or RRCSetupComplete message is transmitted. - The RRCResumeRequest or RRCResumeComplete message is transmitted. The RRCRestablishmentRequest or RRCReestablishmentComplete message is transmitted.

[0049] When the remote UE identifies that a particular timer has expired, The local ID is not valid, or The UE is not able to encapsulate the local identity in the adaptation layer.

[0050] Only if the local identity of the remote UE is valid, the remote UE can encapsulate the local identity in the PC5 adaptation layer header.

[0051] Example 1A

[0052] In the SL relay, there is a PC5 adaptation layer header or a Uu adaptation layer header, and the remote UE can encapsulate a local ID into the PC5 adaptation layer header, or the relay UE can encapsulate a local ID of the remote UE into the Uu adaptation layer header. In Example 1A, a technique is described about how the relay UE determines whether to encapsulate a local ID into the adaptation layer header.

[0053] In some embodiments, a specific set of local IDs or a specific local ID is used to indicate whether the relay UE needs to encapsulate the local ID in the adaptation layer header for the traffic of the remote UE, for example, the local ID being set to all zeros means that the relay UE needs to encapsulate the local ID in the adaptation layer.

[0054] In some embodiments, an indication is included in the PC5 adaptation layer header to indicate whether the relay UE needs to encapsulate the local ID in the Uu adaptation layer header.

[0055] In some embodiments, an indication in the PC5 adaptation layer header is included to indicate whether the local ID in the PC5 adaptation layer is empty, not valid, or valid.

[0056] If the relay UE recognizes that the local ID of the adaptation layer is a specific local ID or one of a specific set of local IDs, the relay UE encapsulates the local ID of the remote UE in the Uu adaptation layer header.

[0057] If the PC5 adaptation layer header contains an indication to indicate that the relay UE needs to encapsulate the local identity in the Uu adaptation layer, the relay UE encapsulates the local identity of the remote UE in the Uu adaptation layer header.

[0058] If the indication in the PC5 adaptation layer header indicates that the local ID in the PC5 adaptation layer header is empty or not valid, the relay UE encapsulates the local ID of the remote UE in the Uu adaptation layer header.

[0059] A particular local ID may be all zeros or all ones.

[0060] Example 2

[0061] Considering that signaling radio bearers (SRBs) and dedicated radio bearers (DRBs) share the same ID space (e.g., both IDs 1, 2, and 3 can be used for SRBs and DRBs), this Example 2 section describes how to distinguish between SRBs and DRBs.

[0062] In some embodiments, when a remote UE connects with a gNB via a relay UE, one ID or set of IDs cannot be used for the DRB or SRB of the remote UE.

[0063] In some embodiments, the adaptation layer header includes an indication of whether the corresponding data is from an SRB or a DRB. In some embodiments, the adaptation layer header is on a PC5 interface or a Uu interface.

[0064] In some embodiments, the SRB and the DRB do not share the same bearer mapping configuration.

[0065] 3 illustrates an example flowchart for transmitting assistance information. Operation 302 includes receiving, by a first communication device, a priority indication indicating a first priority associated with the assistance information. Operation 304 includes transmitting, by the first communication device, the assistance information to a second communication device, where the assistance information is transmitted earlier than transmission of the data in response to the first priority associated with the assistance information being higher than the second priority of the data.

[0066] In some embodiments, an exemplary wireless communication method includes receiving, by a first communication device, a priority indication indicating a first priority associated with the assistance information and transmitting, by the first communication device, the assistance information to a second communication device, where the assistance information is transmitted in a time domain relative to a transmission of the data by comparing the first priority associated with the assistance information to a second priority of the data. For example, the assistance information is transmitted earlier than a transmission of the data in response to the first priority associated with the assistance information being higher than the second priority of the data. In another example, the assistance information is transmitted after a transmission of the data in response to the first priority associated with the assistance information being lower than the second priority of the data.

[0067] In some embodiments, the first priority is a priority of a signaling including the assistance information. In some embodiments, the first communication device receives a priority indication from the network device. In some embodiments, the first communication device receives a priority indication from the second communication device. In some embodiments, the first priority associated with the assistance information is the same as a highest data priority at the second communication device when the first communication device receives a request from the second communication device to trigger the first communication device to transmit the assistance information. In some embodiments, the first priority associated with the assistance information is the same as a third priority of another signaling received by the first communication device from the second communication device, the other signaling triggering the first communication device to transmit the assistance information.

[0068] In some embodiments, the first communication device receives a list of one or more frequencies and / or a list of one or more time values ​​from the second communication device, and the first communication device transmits the assistance information using frequencies and / or time values ​​from the list of one or more frequencies and / or the list of one or more time values. In some embodiments, the first communication device includes a first user equipment (UE) and the second communication device includes a second UE.

[0069] 4 illustrates an example flowchart for transmitting an assistance configuration. Operation 402 includes receiving, by a second communication device, a priority indication indicating a first priority associated with the assistance configuration. Operation 404 includes transmitting, by the second communication device, the assistance configuration to the first communication device, the assistance configuration being transmitted earlier than transmission of the data in response to the first priority associated with the assistance information being higher than the second priority of the data.

[0070] In some embodiments, an exemplary wireless communication method includes receiving, by a second communication device, a priority indication indicating a first priority associated with an assisting configuration, and transmitting, by the second communication device, the assisting configuration to the first communication device, where the assisting configuration is transmitted in a time domain relative to a transmission of the data by comparing the first priority associated with the assisting configuration to a second priority of the data. For example, the assisting configuration is transmitted earlier than a transmission of the data in response to the first priority associated with the assisting configuration being higher than the second priority of the data. In another example, the assisting configuration is transmitted after a transmission of the data in response to the first priority associated with the assisting configuration being lower than the second priority of the data.

[0071] In some embodiments, the first priority is a priority of the signaling including the assistance configuration. In some embodiments, the second communication device receives a priority indication from the network device. In some embodiments, the first priority associated with the assistance configuration is the same as the highest data priority at the second communication device. In some embodiments, the second communication device receives any one or more of a Hybrid Automatic Repeat Request (HARQ) retransmission count indicating a number of times HARQ retransmissions are allowed to retransmit the signaling or assistance information, a packet delay budget (PDB) for the signaling or for the assistance information, a packet error rate (PER) configured for the signaling or for the assistance information, and / or a HARQ enable or disable attribute for the signaling or for the assistance information. In some embodiments, the first communication device includes a first user equipment (UE) and the second communication device includes a second UE.

[0072] In some embodiments, an apparatus for wireless communication comprises a processor configured to perform the method(s) described in this patent specification. In some embodiments, a non-transitory computer readable program storage medium having code stored thereon causes the processor to perform the method(s) described in this patent specification when the code is executed by the processor.

[0073] FIG. 5 illustrates an example block diagram of a hardware platform 500 that may be part of a network device (e.g., a base station) or a communication device (e.g., a user equipment (UE)). The hardware platform 500 includes at least one processor 510 and a memory 505 having instructions stored therein. The instructions executed by the processor 510 configure the hardware platform 500 to perform the operations described in FIGS. 1-4 and 6 and in various embodiments described in this patent specification. The transmitter 515 transmits or transmits information or data to another device. For example, a network device transmitter can transmit a message to a user equipment (also known as a communication device). The receiver 520 receives information or data transmitted or transmitted by another device. For example, a user equipment can receive a message from another user equipment.

[0074] The above-mentioned embodiment is applied to wireless communication. Figure 6 shows an example of a wireless communication system (e.g., a 5G or NR cellular network) including a base station 620 and one or more user equipments (UEs) 611, 612, and 613. In some embodiments, the UE accesses a BS (e.g., a network) using a communication link to the network (as shown by dashed arrows 631, 632, 633, sometimes referred to as an uplink direction), and then enables subsequent communication from the BS to the UE (as shown by arrows 641, 642, 643, sometimes referred to as a downlink direction). In some embodiments, the BS transmits information to the UE (as shown by arrows 641, 642, 643, sometimes referred to as a downlink direction), and then enables subsequent communication from the UE to the BS (as shown by dashed arrows 631, 632, 633, sometimes referred to as an uplink direction). The UE may be, for example, a smartphone, a tablet, a mobile computer, a Machine-to-Machine (M2M) device, an Internet of Things (IoT) device, and so on.
