Abstract
A method and apparatus for data transfer in RRC_INACTIVE state is provided. Method for data transfer in RRC_INACTIVE state includes initiating the second resume procedure, starting a first timer, receiving a RRCResume and stopping the first timer. Buffer status reporting is performed based on a first BSR configuration and a first LCG if the first timer is running and performed based on a second BSR configuration and the first LCG if the first timer is not running.
Claims3
A method by a terminal, the method comprising:
- receiving, by the terminal, an RRCReconfiguration, wherein the RRCReconfiguration includes one or more first Logical Channel Groups (LCGs) and a first Buffer Status Report-Config (BSR-config), and wherein each of the one or more first LCGs corresponds to at least a Data Radio Bearer (DRB);
- receiving, by the terminal, an RRCRelease, wherein the RRCRelease includes first information for a second resume procedure, and wherein the first information for the second resume procedure includes a Signaling Radio Bearer2 (SRB2) indicator and a DRB list;
- determining, by the terminal, radio bearers configured for the second resume procedure based on the first information for the second resume procedure;
- receiving, by the terminal, system information, wherein the system information includes a first timer value, a second timer value, a first threshold, and a second threshold, and wherein the first threshold is related to a reference signal received power and the second threshold is related to a data volume;
- initiating, by the terminal, the second resume procedure;
- starting, by the terminal, a first timer after applying a second BSR-config;
- receiving, by the terminal, an RRCResume;
- and
- stopping, by the terminal, the first timer,
- wherein the terminal performs buffer status reporting based on:
- the second BSR-config and the first LCGs in case that the first timer is running;
- and
- the first BSR-config and the first LCGs in case that the first timer is not running.

- receive an RRCRelease, wherein the RRCRelease includes first information for a second resume procedure, and wherein the first information for the second resume procedure includes a Signaling Radio Bearer2 (SRB2) indicator and a DRB list;
- determine radio bearers configured for the second resume procedure based on the first information for the second resume procedure;
- receive system information, wherein the system information includes a first timer value, a second timer value, a first threshold, and a second threshold, and wherein the first threshold is related to a reference signal received power and the second threshold is related to a data volume;
- initiate the second resume procedure;
- start a first timer after applying a second BSR-config;
- receive an RRCResume;
- and
- stop the first timer,
- wherein the terminal performs buffer status reporting based on:
- the second BSR-config and the first LCGs in case that the first timer is running;
- and
- the first BSR-config and the first LCGs in case that the first timer is not running.
