- the base station may be a macro base station
- Sidelink communication can also be called proximity services (ProSe) communication, unilateral communication, sidelink communication, and device to device (D2D) communication.
- ProSe proximity services
- D2D device to device
- D2D communication is different from the traditional cellular system in which communication data is received or sent through network devices. Instead, it adopts the method of direct communication from UE to UE, so it has higher spectrum efficiency and lower transmission delay.
- the 3rd generation partnership project (3GPP) defines two transmission modes: mode A and mode B.
- Figure 2A exemplarily shows mode A of the sidelink transmission technology.
- mode A the transmission resources of UE 120 are allocated by the network device 110, and UE 120 transmits data on the sidelink according to the resources allocated by the network device.
- the network device 110 can allocate resources for a single transmission to UE 120, or it can allocate resources for semi-static transmission to UE 120.
- Figure 2B exemplarily shows mode B of the sidelink transmission technology. In mode B, UE 120 selects resources from the resource pool for data transmission.
- D2D is divided into the following different phases for research.
- Phase 1 ProSe.
- D2D communication is studied for the ProSe project.
- the ProSe project is mainly aimed at public safety services.
- the location of the resource pool in the time domain can be configured, for example, the resource pool is non-continuous in the time domain, so that the UE can send/receive data non-continuously on the side link, thereby achieving power saving.
- vehicle networking communication scenarios mainly for relatively high-speed vehicle-to-vehicle communication and vehicle-to-person communication services.
- the power efficiency of the UE is not the main problem of the vehicle networking system.
- the main problem of the vehicle networking system is the delay of data transmission, so the system design requires the UE to perform continuous transmission and reception.
- Phase 4 Multi-carrier.
- a multi-carrier mechanism is introduced.
- the multi-carrier mechanism is reflected in the fact that the UE can support packet segmentation, thereby transmitting packets through multiple carriers to improve the data transmission rate.
- the UE can perform packet replication, thereby replicating an identical packet into multiple (such as two) packets; then, the UE can send the multiple packets separately using multiple carriers, thereby improving the reliability of transmission.
- V2X supports UE to perform sidelink data packet duplication (or sidelink packet duplication) at the packet data convergence protocol (PDCP) layer.
- PDCP packet data convergence protocol
- a PDCP packet data unit (PDU) can be duplicated (PDCP duplication) at the PDCP entity, and then two packet data protocol (PDP) PDUs duplicated by the same PDCP entity are submitted to two different radio link control (RLC) entities and associated with two different sidelink logical channels.
- RLC radio link control
- Different PDP PDUs duplicated by the same PDCP entity are only allowed to be transmitted on different sidelink carriers.
- the UE may activate or deactivate the packet replication function for the sidelink based on (pre) configuration.
- Sidelink packet replication is not applicable for transmissions with Rel-14 transmission profile (see TS 23.285).
- the ProSe per-packet reliability (PPPR) value for supporting sidelink packet replication may be (pre) configured via a PPPR threshold.
- PPPR ProSe per-packet reliability
- the UE may report the amount of data packets associated with one or more PPPR values and the destination of these packets via a sidelink buffer status report (BSR).
- BSR sidelink buffer status report
- the mapping of PPPR values to logical channel groups may be configured by the network device and the PPPR value is reflected by the logical channel group identity (ID) associated with the PPPR value contained in the sidelink BSR.
- ID logical channel group identity
- a list of one or more PPPR values may be reported by a UE in a radio resource control (RRC) connection in the sidelink UE information.
- RRC radio resource control
- NR V2X is not limited to broadcast scenarios, but is further expanded to unicast and multicast scenarios, and the application of V2X is studied in these scenarios.
- NR V2X Similar to LTE V2X, NR V2X also defines two resource allocation modes: mode 1 and mode 2. Furthermore, the UE may be in a hybrid mode. In other words, the UE can acquire resources based on mode 1 and mode 2 at the same time.
- the resource acquisition method can be indicated by a sidelink grant.
- the sidelink grant can be used to indicate the time-frequency position of the physical sidelink control channel (PSCCH) and the physical sidelink shared channel (PSSCH) resources.
- PSCCH physical sidelink control channel
- PSSCH physical sidelink shared channel
- NR V2X Different from LTE V2X, in addition to the non-feedback, UE-initiated hybrid automatic repeat request (HARQ) retransmission, NR V2X also introduces feedback-based HARQ retransmission. Feedback-based HARQ retransmission can be applied to unicast communication as well as multicast communication.
- HARQ hybrid automatic repeat request
- NR V2X Similar to LTE V2X, in NR V2X, power efficiency is not the main problem faced by NR V2X because the on-board system has the ability to continuously supply power.
- the main problem faced by NR V2X is the delay of data transmission. Therefore, NR V2X requires UE to continuously send and receive in system design.
- the UE in sidelink communication will trigger the RRC reconfiguration process of the sidelink in one or more of the following scenarios: releasing the sidelink data bearer in unicast communication; establishing the sidelink data bearer in unicast communication; modifying the relevant configuration of the sidelink data bearer in unicast communication; releasing the PC5 relay RLC channel between the layer 2 relay UE and the remote UE in the U2N relay scenario; establishing the PC5 relay RLC channel between the layer 2 relay UE and the remote UE in the U2N relay scenario; modifying the configuration parameters related to the PC5 relay RLC channel between the layer 2 relay UE and the remote UE in the U2N relay scenario; reconfiguration of NR sidelink measurement reporting related parameters; reconfiguration of sidelink channel state information (CSI) reference signal resources and CSI reporting delay boundaries; reconfiguration of sidelink DRX for the opposite UE.
- CSI sidelink channel state information
- the remote UE performs measurement reporting and includes information such as the relay UE identifier, serving cell identifier, and reference signal receiving power (RSRP) measurement value in the measurement reporting information.
- RSRP reference signal receiving power
- the remote UE performs a link switch from a non-direct path to a direct path
- the sidelink reference signal receiving power can be used for measurements on the sidelink.
- the sidelink discovery reference signal receiving power can be used for measurements on the sidelink.
- two new measurement reporting trigger events are defined for the switch from the UE to the relay UE of the network:
- Event 1 When the link quality of the relay UE is lower than the configured threshold, and, optionally, the link quality of the neighboring cell is higher than the configured threshold, the remote UE performs measurement reporting;
- Event 2 When the link quality of the serving cell is lower than a configured threshold, and, optionally, when the link quality of the relay UE is higher than the configured threshold, the remote UE performs measurement reporting.
- a new timer is introduced.
- the remote UE receives the RRC reconfiguration message indicating the switch from the direct link to the indirect link, the remote UE starts the timer.
- the remote UE performs RRC reestablishment.
- the network device will configure the bearer identifier for the remote UE and the relay UE for end-to-end data transmission of the relay UE.
- the network device will additionally configure the bearer parameters on the PC5 interface between the relay UE and the remote UE.
- the network device will map the bearer identifier with the PC5 RLC channel identifier (PC5 RLC channel ID) (see SL-SRAP-Config information element and SL-RLC-ChannelConfig information element below).
- the relay UE can learn the specific configuration information used by the remote UE through the PC5 RLC channel identifier. However, the relay UE cannot learn the specific information of the QoS of the corresponding service transmitted by the remote UE using this configuration information.
- the remote UE In the U2N relay scenario, the remote UE sometimes wants to obtain messages sent by the network device (such as system messages and/or paging messages). However, there is currently no suitable solution for how the remote UE should obtain the messages sent by the network device.
- the remote UE sends a request message to the first relay UE to request the first relay UE to send a message sent by the network device.
- the introduction of the request message helps the remote UE to obtain the message sent by the network device.
- the first message may include one or more of the following: a first system message and a first paging message.
- the request message may include indication information for indicating the type of the system message.
- the indication information may indicate that the first system message is a system information block 1 (SIB1) or SIB2.
- the request message may include indication information for indicating one or more of: an identifier of the UE associated with the first paging message; and the length of a paging cycle of the first paging message.
- the method of Figure 3 may further include step S320, that is, the remote UE receives a first message sent by the first relay UE.
- the first relay UE may obtain the first message from the network device and then forward the first message to the remote UE.
- the remote UE may be connected to the network device via a relay UE.
- the remote UE may be connected to the network device via a multi-hop relay UE.
- This connection scenario is referred to as a multi-hop relay scenario below.
- the remote UE may establish multiple connections with a network device (which may be one network device or multiple network devices) through multiple relay UEs.
- a network device which may be one network device or multiple network devices
- This connection scenario is referred to as a multi-path relay scenario below.
- the network device may receive the request message sent by the remote UE through one or more relay UEs.
- the one or more relay UEs may include not only the first relay UE mentioned above, but also other relay UEs.

- the network device may send a first message to the third relay UE. Further, in some embodiments, when sending the first message, the network device may further carry one or more of the following information: an identifier of a remote UE, an identifier of a first relay UE, and an identifier of a relay UE between the first relay UE and a third relay UE.
- the third relay UE may send the first message to the first relay UE.
