Embodiment 1

[0188] Below, combine figure 2 The method executed by the user equipment according to Embodiment 1 of the present disclosure will be described.

[0189] figure 2 is a flow chart showing the method executed by the user equipment according to Embodiment 1 of the present disclosure.

[0190] Such as figure 2 As shown, in the first embodiment of the present disclosure, the steps performed by the user equipment UE include: step S101 and step S102.

[0191] Specifically, in step S101, a timing advance command is received.

[0192] For example, a timing advance command is received from the base station at time slot n. in,

[0193] ●The timing advance command can indicate an index value (denoted as T A ).

[0194] • The timing advance command may be included in a RAR, which may be a response to a random access preamble. For example, the RAR may be a MAC PDU, which may include a MAC sub-PDU (MAC subPDU); the payload of the MAC sub-PDU may include a "Timing Advance Command" f...

Embodiment 2

[0329] Below, combine image 3 The method performed by the user equipment according to Embodiment 2 of the present disclosure will be described.

[0330] image 3 It is a flow chart showing the method executed by the user equipment according to the second embodiment of the present disclosure.

[0331] Such as image 3 As shown, in the second embodiment of the present disclosure, the steps performed by the user equipment UE include: step S201 and step S202.

[0332] Specifically, in step S201, configuration information of parameters related to SL SSB (such as whether the parameters have been configured, or the configured values ​​of the parameters) is acquired. For example, the configuration information is obtained from predefined information or pre-configuration information, or the configuration information is obtained from the base station (for example, the configuration information is obtained through DCI or MAC CE or RRC signaling), or the configuration information is ob...

Embodiment 3

[0816] Below, combine Figure 4 The method performed by the user equipment according to Embodiment 3 of the present disclosure will be described.

[0817] Figure 4 is a flow chart showing the method executed by the user equipment according to the third embodiment of the present disclosure.

[0818] Such as Figure 4 As shown, in the third embodiment of the present disclosure, the steps performed by the user equipment UE include: step S301 and step S302.

[0819] Specifically, in step S301, configuration information of parameters related to SL SSB is acquired. For example, the configuration information is obtained from predefined information or pre-configuration information, or the configuration information is obtained from the base station (for example, the configuration information is obtained through DCI or MACCE or RRC signaling), or the configuration information is obtained from other UEs information, or use the default configuration when the parameter is not configur...

Abstract

The invention provides a method executed by user equipment. The method comprises the following steps: receiving a timing advance command in a time slot n; and determining the time of applying the uplink transmission timing adjustment according to the time slot n for receiving the timing advance command and / or other information related to the uplink transmission timing adjustment.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and specifically relates to a method executed by user equipment and corresponding user equipment. Background technique [0002] In March 2016, at the 3rd Generation Partnership Project (3rd Generation Partnership Project: 3GPP) RAN#71 plenary session, a new research project on 5G technical standards (see Non-Patent Document 1) was approved. The purpose of this research project is to develop a new radio (New Radio: NR) access technology to meet all application scenarios, requirements and deployment environments of 5G. NR has three main application scenarios: Enhanced Mobile Broadband Communication (Enhanced MobileBroadband: eMBB), Massive Machine Type Communication (massive Machine Type Communication: mMTC) and Ultra-Reliable and Low Latency Communications (Ultra-Reliable and Low Latency Communications: URLLC). In June 2017, at the 3rd Generation Partnership Project (3rd G...
