Method and device used for discontinuous reception in wireless communication
View Patent ↗The present disclosure provides a method and device used for discontinuous reception (DRX) for wireless communications. A first node receives first information, the first information indicates a first identity (ID); determines a start time of a first timer according to the first ID; at the start time of the first timer, starts the first timer; when the first timer is running, monitors a first radio signal in each candidate slot; herein, the first ID belongs to a link-layer ID; the start time of the first timer is a start time of a first time interval. The present disclosure determines a start time of a first timer according to a first ID, which can randomize start times of user's DRX, avoiding possible system congestion and increasing transmission accuracy.
1. A first node for wireless communications, comprising:
a first receiver, receiving first information, the first information indicating a first identity (ID), the first ID belonging to a link-layer ID; determining a start time of a first timer according to the first ID; at the start time of the first timer, starting the first timer; and
a second receiver, when the first timer is running, monitoring a first radio signal in each candidate slot;
wherein the start time of the first timer is a start time of a first time interval; a remainder of an index of a first subframe in an FN (Frame Number) period divided by a first time length is the same as a remainder of the first ID divided by the first time length;
the first subframe comprises the first time interval.
2. The first node according to claim 1 , comprising:
the second receiver, when the first timer is running, updating the first timer in each second time interval.
3. The first node according to claim 1 , comprising:
the first receiver, receiving second information, the second information indicating a first expiration value of the first timer.
4. The first node according to claim 1 , wherein the first time length is a drx-ShortCycle, or a drx-LongCycle.
5. The first node according to claim 1 , comprising:
the first receiver, receiving third information, the third information indicating an FN and a subframe number;
wherein the FN and the subframe number are used for determining the index of the first subframe in the FN period.
6. The first node according to claim 1 , comprising:
the first receiver, receiving a first signaling;
wherein the first signaling is a MAC (Medium Access Control) control element used for DRX (Discontinuous Reception).
7. A second node for wireless communications, comprising:
a second transmitter, transmitting first information, the first information comprising a first identity) ID, the first ID belonging to a link-layer ID; and
a third transmitter, when a first timer is running, transmitting a first radio signal in a candidate slot;
wherein the first ID is used for indicating a start time of the first timer; at the start time of the first timer, the first timer is started; the start time of the first timer is a start time of a first time interval; a remainder of an index of a first subframe in an FN (Frame Number) period divided by a first time length is the same as a remainder of the first ID divided by the first time length;
the first subframe comprises the first time interval.
8. The second node according to claim 7 , comprising:
the second transmitter, transmitting second information, the second information comprising a first expiration value of the first timer.
9. The second node according to claim 7 , wherein the first time length is a drx-ShortCycle, or a drx-LongCycle.
10. The second node according to claim 7 , comprising:
the second transmitter, transmitting third information, and the third information indicating an FN and a subframe number;
wherein the FN and the subframe number are used for indicating the index of the first subframe in the FN period.
11. The second node according to claim 7 , comprising:
the second transmitter, transmitting a first signaling;
wherein the first signaling is a MAC (Medium Access Control) control element used for DRX (Discontinuous Reception).
12. A method in a first node for wireless communications, comprising:
receiving first information, the first information indicating a first (identity) ID, the first ID belonging to a link-layer ID; determining a start time of a first timer according to the first ID; at the start time of the first timer, starting the first timer; and
when the first timer is running, monitoring a first radio signal in each candidate slot;
wherein the start time of the first timer is a start time of a first time interval; a remainder of an index of a first subframe in an FN (Frame Number) period divided by a first time length is the same as a remainder of the first ID divided by the first time length;
the first subframe comprises the first time interval.
13. The method in a first node according to claim 12 , comprising:
when the first timer is running, updating the first timer in each second time interval.
14. The method in a first node according to claim 12 , comprising:
receiving second information, the second information indicating a first expiration value of the first timer.
15. The method in a first node according to claim 12 , wherein the first time length is a drx-ShortCycle, or a drx-LongCycle.
16. The method in a first node according to claim 12 , comprising:
receiving third information, the third information indicating an FN and a subframe number;
wherein the FN and the subframe number are used for determining the index of the first subframe in the FN period.
17. The method in a first node according to claim 12 , comprising:
receiving a first signaling;
wherein the first signaling is a MAC (Medium Access Control) control element used for DRX (Discontinuous Reception).
