Method and device used in communication node for wireless communication
View Patent ↗The present disclosure discloses a method and a device in a communication node for wireless communications. A first node transmits a first RRC signaling, and starts a first timer; and receives a first information block, the first RRC signaling being used to trigger the first information block; and, in response to the behavior of receiving a first information block, stops or restarts the first timer; herein, the first RRC signaling is used for requesting data transmission; the first information block belongs to a lower layer relative to an RRC layer. The present disclosure ensures small data transmission; avoids the impact of timer overrunning on data transmission; and uses existing signaling to reduce signaling overhead.

wherein the phrase of the second RRC signaling indicating an expiration value of the first timer comprises that: the second RRC signaling comprises a RRCRelease message, and the RRCRelease message comprises a SuspendConfig IE, the SuspendConfig IE comprising a field, the field indicating the expiration value of the first timer.
10. The first node according to any of claim 1 , wherein the second RRC signaling is used to trigger the first node's entry into a first status from a second status; the first status comprises an RRC_INACTIVE status.
11. The first node according to any of claim 1 , wherein in response to the action of receiving a first-type information block, the first timer is stopped.
12. The first node according to any of claim 1 , wherein in response to the action of receiving a first-type information block, the first timer is restarted.
13. The first node according to any of claim 1 , comprising:
the first receiver, in response to the action of receiving a first-type information block, transmitting fourth indication to an RRC layer from a layer processing the first-type information block, the fourth indication being used to restart the first timer.
14. The first node according to any of claim 1 , comprising:
the first transmitter, transmitting a second uplink radio signal, and, in response to the action of transmitting the second uplink radio signal, restarting the first timer.
15. The first node according to claim 14 , wherein the second uplink radio signal is transmitted on a PUSCH.
16. The first node according to claim 14 , wherein the second uplink radio signal is used to trigger the first-type information block; in response to the action of receiving the first-type information block, the first timer is stopped.
17. The first node according to any of claim 1 , comprising:
the first receiver, performing an operation of entering RRC_IDLE status when the first timer overruns.
18. A second node for wireless communications, comprising:
a second receiver, receiving a first RRC signaling; and
