Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to a sidelink discontinuous reception implementation method and device and terminal. BACKGROUND

[0002] The Long Term Evolution (LTE) system supports sidelink (SL) since the 12th release, such as Figure 1 As shown in the schematic diagram of the LTE uplink / downlink / sidelink, the sidelink is used for direct data transmission between user equipment (UE) without passing through a network device. The current sidelink transmission mainly includes broadcast, groupcast, and unicast.

[0003] Both LTE and NR introduce a DRX (Discontinuous Reception) mechanism to achieve power saving of the UE by configuring DRX on and off time. The DRX is configured periodically, such as Figure 2As shown, at the beginning of each DRX cycle, a short continuous reception state called on duration is entered first, and in the on duration, the terminal needs to monitor the physical downlink control channel (PDCCH) to determine whether there is resource allocation for itself. If no data scheduling and data transmission occur in the on duration, the terminal will enter an inactive state until the next DRX cycle, and can receive downlink transmission again when the drx-onDurationTimer starts. During the on duration, if the UE is scheduled and receives data in a certain slot, it is likely to be scheduled in the next few slots. Therefore, when the UE is scheduled to transmit data for the first time, the timer drx-InactivityTimer is started or restarted, and the UE will remain in the active state until the timer expires. When the UE receives a discontinuous reception control media access layer control element (Discontinuous Reception Command Media Access Control Control Element, DRXCommand MAC CE) from the base station, the relevant DRX timers (such as drx-onDurationTimer and drx-InactivityTimer) are stopped, so that the UE enters the DRX sleep / off state, and power saving of the UE is realized.

[0004] The control granularity of the current Uu DRX command MAC CE is per UE. For SL, considering that a UE can simultaneously perform multiple unicast / groupcast services, multiple unicast connections / groupcast groups can be established in the UE at the same time, and therefore, the per UE granularity of the Uu DRX command MAC CE format has low flexibility and is not suitable for the DRX mechanism in the SL scenario. SUMMARY

[0005] Embodiments of the present application provide a sidelink discontinuous reception implementation method and device and terminal, which can solve the problem of low flexibility of the current Uu DRX command MAC CE format and unsuitability for the DRX mechanism in the SL scenario.

The following description describes a New Radio (NR) system for example purposes, and NR terminology is used in most of the following description, but these techniques can also be applied outside of NR system applications, such as 6th Generation (6G) communication systems. th

[0038] Figure 3 ​A block diagram of a wireless communication system to which embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network side device 12. The terminal 11 can also be referred to as a terminal device or a user terminal (UE). The terminal 11 can be a terminal side device such as a mobile phone, a tablet personal computer, a laptop computer, a personal digital assistant (PDA), a palm computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (MID), a wearable device, or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc. The wearable device includes a smart watch, a bracelet, a headset, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application.

The base station is not limited to a specific technical term as long as the same technical effect is achieved. It should be noted that only a base station in an NR system is taken as an example in the embodiments of the present application, but the specific type of the base station is not limited.

[0039] The format design of the Uu DRX command MAC CE in the related art is very simple, such as Figure 4As shown, the DRX command MAC CE only has a MAC subheader, and the control granularity of the Uu DRX command MAC CE is per UE. Considering that one UE can simultaneously perform multiple unicast / groupcast services in the SL scenario, multiple unicast connections / groupcast groups can be simultaneously established in one UE, therefore, the per UE granularity of the Uu DRX command MAC CE format has low flexibility, and is not suitable for the DRX mechanism in the SL scenario. In order to solve the above problems, the embodiment of the present application provides a sidelink discontinuous reception implementation method, device and terminal.

[0040] The sidelink discontinuous reception implementation method, device and terminal provided by the embodiment of the present application will be described in detail in combination with some embodiments and application scenarios thereof, with reference to the accompanying drawings.

[0084] Reference Figure 7 , Figure 7 In the MAC CE payload, logical channel group (LCG) information and direction information are taken as examples to indicate the validity object and / or range of the SL DRX command MAC CE. In fact, the information carried in the MAC CE payload can be a combination of various information, and the application does not limit the arrangement order of the various information.

[0085] In some optional embodiments, in the case where the SL DRX command MAC CE adopts format two, the validity object and / or range of the SL DRX command MAC CE can also be indicated in combination with at least one of SCI and SL-SCH subheader:
