It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

The terminology used in the description of the embodiments of the application herein is for the purpose of describing particular embodiments of the application only and is not intended to be limiting of the application.

The device-to-device communication is based on a side-link (SL) technology of D2D, and unlike a conventional cellular system in which communication data is received or transmitted through a base station, the internet of vehicles system adopts a terminal-to-terminal direct communication mode, so that the system has higher spectral efficiency and lower transmission delay.

Fig. 1 is a schematic diagram of a communication system according to an embodiment of the present application. The transmission resources of the in-vehicle terminals (in-vehicle terminal 121 and in-vehicle terminal 122) are allocated by the base station 110, and the in-vehicle terminals transmit data on the side links according to the resources allocated by the base station 110. Specifically, the base station 110 may allocate resources for single transmission to the terminal, or may allocate resources for semi-static transmission to the terminal.

Fig. 2 is a schematic diagram of another communication system according to an embodiment of the present application. The vehicle-mounted terminals (the vehicle-mounted terminal 131 and the vehicle-mounted terminal 132) autonomously select transmission resources on the resources of the side links to perform data transmission. Optionally, the vehicle-mounted terminal may select the transmission resource randomly, or select the transmission resource by listening.

The embodiment of the application can be applied to the communication system shown in fig. 1.

In order to facilitate a better understanding of embodiments of the application, the terminology associated with the application will be described.

Proximity-based Services (ProSe): device-to-device communication in release12 (release 12, rel-12) or release13 (release 13, rel-13) was studied for the ProSe scenario, which is mainly directed to public safety class traffic.

In ProSe, by configuring the position of the resource pool in the time domain, for example, the resource pool is discontinuous in the time domain, discontinuous data transmission/reception of the UE on the side link is achieved, so that the effect of power saving is achieved.

Internet of vehicles (V2X): in release14 (release 14, rel-14) or release15 (release 15, rel-15), the internet of vehicles system is studied for the scene of vehicle-to-vehicle communication, which is mainly directed to the traffic of vehicle-to-vehicle and vehicle-person communication that moves at a relatively high speed. In V2X, since the in-vehicle system has continuous power supply, power efficiency is not a major problem, and delay of data transmission is a major problem, so that continuous transmission and reception by the terminal device is required in system design.

Wearable device (FeD 2D): in Rel-14, this scenario is studied for a scenario where a wearable device accesses a network through a handset, which is mainly oriented to a scenario of low movement speed and low power access. In FeD2D, the 3GPP concludes that the base station can configure the DRX parameters of the remote terminal through a relay terminal in the pre-research stage.

For a better understanding of the embodiments of the present application, the NR V2X related to the present application will be described.

NR V2X is not limited to broadcast scenes on the basis of LTE V2X, but extends further to unicast and multicast scenes where V2X applications are studied.

Similar to LTE V2X, NR V2X also defines two resource grant modes, mode 1 (corresponding to the communication system shown in fig. 1 above) and mode 2 (corresponding to the communication system shown in fig. 2 above); further, the user may be in a mixed mode, i.e., both mode 1 and mode 2 may be used for resource acquisition. The resource acquisition is indicated by means of a sidelink grant, i.e. the sidelink grant indicates the time-frequency position of the corresponding physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) and physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) resources.

Unlike LTE V2X, NR V2X introduces feedback-based HARQ retransmissions, not limited to unicast communications, but also multicast communications, in addition to feedback-free, UE-initiated hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) retransmissions.

As in LTE V2X, in NR V2X, since the in-vehicle system has continuous power supply, power efficiency is not a major problem, and delay of data transmission is a major problem, and thus continuous transmission and reception by the terminal device is required in system design.

For better understanding of the embodiments of the present application, the manner of obtaining the NR-V2X Mode 1 (Mode 1) resource according to the present application will be described.

The resource allocation manner based on the network scheduling is further classified into dynamic Grant and Configuration Grant (CG). For dynamic authorization, the network allocates side transmission resources to the terminal through downlink control information (Downlink Control Information, DCI); in release16 (Rel-16) NR-V2X, a side-uplink configuration grant (SL CG) was introduced by way of the uplink CG mechanism. When the terminal is configured with the side line configuration authorized transmission resource, and when the side line data arrives, the terminal can use the side line configuration authorized transmission resource to transmit the side line data without re-applying the transmission resource to the network, so that the time delay of the side line transmission can be reduced by the side line configuration authorized transmission resource. The side line configuration authorized transmission resource is a periodic transmission resource, so that the method can be suitable for periodic side line data transmission, and can be used for transmitting non-periodic side line data.

When the terminal has sidestream data to send, the terminal sends a resource request to the base station, including a scheduling request (Scheduling Request, SR) and a buffer status report (Buffer Status Report, BSR), the base station allocates sidestream transmission resources to the terminal according to the BSR of the terminal, and the terminal sends the sidestream data on the sidestream transmission resources allocated by the base station, as shown in fig. 3.

In order to better understand the embodiment of the present application, a relevant side BSR (SL-BSR) mechanism of the present application will be described.

The terminal device transmits a scheduling request (SR or random access) to the base station, and then transmits a SL-BSR, which may include at least a target address index (destination index), a logical channel group identity (Logical Channel Group Identity, LCG ID), and a buffer size (buffer size), as shown in fig. 4. Based on the side-link BSR, the base station may determine that the terminal device has data to be transmitted for side-link communication and estimate resources required to transmit the data. The base station may schedule transmission resources for the side-link communication using the configured radio network temporary identity (Radio Network Temporary Identity, RNTI) for the side-link.

For triggering of the SL-BSR, there are the following trigger conditions:

new data to be transmitted appears in the radio link control (Radio Link Control, RLC) entity or packet data convergence protocol (Packet Data Convergence Protocol, PDCP) entity (if there is any other data to be transmitted, the new data priority is higher than the priority of any logical channel group data to be transmitted for the same destination address, or the destination address is granted that there is no other data to be transmitted at present);

The number of bits remaining after the space for resource grant is allocated for data and the padding BSR for the uplink channel is triggered is equal to or greater than the size of the side uplink BSR (buffer information of at least one logical channel group containing at least one target address);

the side-uplink BSR retransmission timer expires and the medium access control (Media Access Control, MAC) entity has data available for side-uplink transmission;

the side-uplink BSR periodic timer expires;

the side-uplink BSR may also be triggered when the terminal device configures from an autonomous resource selection mode to a network scheduling resource selection mode.

For better understanding of the embodiments of the present application, DRX related to the present application will be described.

The UE can configure discontinuous monitoring physical downlink control channels (Physical Downlink Control Channel, PDCCH) according to DRX to achieve the purpose of saving power, when the PDCCH carries cell radio network temporary identifiers (Cell Radio Network Temporary Identity, C-RNTI) corresponding to the UE, cancel indication RNTI (Cancellation indication RNTI, CI-RNTI), configure scheduling RNTI (Configured Scheduling RNTI, CS-RNTI), interrupt transmission indication RNTI (Interrupted transmission indication RNTI, INT-RNTI), time slot format indication RNTI (Slot Format Indication RNTI, SFI-RNTI), semi-persistent channel state information radio network temporary identifiers (Semi-Persistent Channel State Information Radio Network Temporary Identity, SP-CSI-RNTI), transmission power control physical uplink control channel RNTI (Transmit Power Control Physical Uplink Control Channel RNTI, TPC-PUCCH-RNTI), transmission power control physical uplink shared channel RNTI (Transmit Power Control Physical Uplink Shared Channel RNTI, TPC-PUSCH-RNTI), transmission power control sounding reference signal RNTI (Transmit Power Control Sounding Reference Signal, TPC-SRS-RNTI) and artificial intelligent RNTI (Artificial Intelligence, AI-). The network controls the DRX behavior of the UE by configuring a series of parameters including:

A DRX duration timer (DRX-onduration timer), a DRX slot offset (DRX-Slotoffset), a DRX inactivity timer (DRX-InactyTimer), a downlink DRX retransmission timer (DRX-retransmission TimerDL), an uplink DRX retransmission timer (DRX-retransmission TimerUL), a DRX long cycle start offset (DRX-longCyclostartOffset), a DRX short cycle (DRX-Shortcycle) parameter (optionally): a short DRX cycle (the Short DRX cycle), a DRX short cycle timer (optionally) a downlink HARQ round trip transmission time timer (Downlink HARQ Round Trip Time Timer, HARQ-RTT-TimerDL), an uplink DRX HARQ RTT timer (Uplink DRX HARQ RTT, DRX-HARQ-RTT-timerl), a power save Wakeup (Power Saving Wakeup, ps-Wakeup) (optionally), power save transmission of other periodic channel state information (Power Saving Transmit Other Periodic Channel State Information, ps-fransmit other periodic csi) (optionally), power save transmission of periodic layer 1 reference signal received power (Power Saving Transmit Periodic L1 Reference Signal Received Power, ps-fransmit periodic l 1-RSRP) (optionally).

Wherein the UE will be in DRX active state as follows:

the drx-ondurationTimer or drx-InactivityTimer run period;

drx-retransmission timer DL or drx-retransmission timer UL run time;

a random access contention resolution timer (ra-contentionresolution timer) or a message B response window (msgB-response window) is running;

there are outstanding scheduling requests (Scheduling Request, SR);

the PDCCH indicates that there is a new transmission period.

In order to facilitate better understanding of the embodiments of the present application, the technical problems to be solved by the present application will be described.

In the mode 1 (mode 1) mechanism, the network does not know which destination address of the data is used for transmitting the sidelink grant resource sent to the originating device, so the network cannot know the running condition of a DRX deactivation timer (DRX-inactivity timer) or a DRX retransmission timer (DRX-retransmission timer) of multiple destination addresses, and cannot accurately determine the reasonable sidelink grant time.

Based on the above problems, the application provides a sidestream communication scheme, and the network equipment can configure reasonable sidestream authorized resources so as to optimize sidestream communication.

The technical scheme of the application is described in detail below through specific embodiments.

Fig. 5 is a schematic flow chart of a method 200 of wireless communication according to an embodiment of the application, as shown in fig. 5, the method 200 of wireless communication may include at least some of the following:

The embodiment of the application is suitable for a resource acquisition mode in a mode 1, namely, transmission resources of the originating equipment are distributed by network equipment (such as a base station), and the originating equipment transmits information on a side downlink according to the resources distributed by the network equipment.

In the sidestream communication, when the receiving end device is in a DRX active state, the transmitting end device needs to send information to the receiving end device so as to ensure that the sidestream transmission is successful, namely that sidestream authorized resources acquired by the transmitting end device need to be in the wake-up time of the receiving end device.

For example, the first time period includes n ms or n time units, n is a positive integer, and n+.1.
