Abstract
A discontinuous reception method includes performing sidelink-based discontinuous reception for a second terminal according to first indication information and/or first configuration information for discontinuous reception. The first configuration information includes configuration information of a timer, and the timer is used to indicate whether the first terminal needs to monitor control signaling and/or data from the second terminal. The first indication information includes sidelink control information and is used to indicate the first terminal to receive a first resource for initial transmission and retransmission and/or a feedback resource.
Claims13
A discontinuous reception method, performed by a first terminal and comprising:
- performing sidelink-based discontinuous reception for a second terminal according to first indication information and/or first configuration information for discontinuous reception, wherein the first configuration information comprises configuration information of a timer, the timer is used to indicate whether the first terminal needs to monitor control signaling and/or data from the second terminal, and the first indication information comprises sidelink control information and is used to indicate the first terminal to receive a first resource for initial transmission and retransmission and/or a feedback resource;
- wherein
- the performing sidelink-based discontinuous reception for a second terminal according to first indication information and/or first configuration information for discontinuous reception comprises:
- in a case that the first configuration information comprises configuration information of a first timer and configuration information of a second timer, performing sidelink-based discontinuous reception based on the first timer;
- wherein the first timer is used to indicate that the first terminal does not need to monitor the control signaling and/or data from the second terminal during running of the first timer, the configuration information of the first timer comprises a first duration used for indicating a timing length of the first timer, and the second timer is used to indicate that the first terminal needs to monitor the control signaling and/or data from the second terminal during running of the second timer;
- the first duration is determined based on at least one of the following:
- duration between two adjacent first resources, or duration between a resource for sending feedback information and a next first resource;
- and
- the performing sidelink-based discontinuous reception based on the first timer comprises:
- starting the first timer at a first time;
- and
- starting the second timer after the first timer exceeds the first duration;
- wherein
- the first time is after at least one of the following time:
- the (n−1)-th first resource;
- or
- a second quantity of symbols or slots after the resource on which the feedback information sent for the (n-1)-th first resource is located.

A discontinuous reception method, performed by a second terminal and comprising:
- performing resource selection or reselection based on first configuration information for discontinuous reception and/or a resource on which feedback information is located;
- wherein the first configuration information comprises configuration information of a timer, and the timer is used to indicate whether a first terminal needs to monitor control signaling and/or data from the second terminal;
- wherein
- the performing resource selection or reselection based on first configuration information for discontinuous reception and/or a resource on which feedback information is located comprises:
- in a case that the first configuration information comprises configuration information of a first timer and/or configuration information of a second timer, determining a position of a second resource based on the first timer and/or the resource on which the feedback information is located, wherein the second resource is a transmission resource corresponding to a time of running the first timer of the first terminal;
- and
- selecting a transmission resource other than the second resource in a resource selection or reselection process;
- wherein
- the first timer is used to indicate that the first terminal does not need to monitor the control signaling and/or data from the second terminal during running of the first timer, the configuration information of the first timer comprises a first duration used for indicating a timing length of the first timer, and the second timer is used to indicate that the first terminal needs to monitor the control signaling and/or data from the second terminal during running of the second timer;
- and
- the first duration is determined based on at least one of the following:
- duration between two adjacent first resources, or duration between a resource for sending feedback information and a next first resource.
