US 10,708,940 B2 · Method and apparatus for reporting buffer state by user equipment in communication system

Abstract

Provided is a method for reporting a buffer state by a user equipment accessing a first eNB and a second eNB in a communication system, the method comprising the steps of: triggering a buffer state report for new data when the new data is generated; selecting at least one eNB to which the buffer state report is to be transmitted, on the basis of the amount of uplink data to be transmitted; transmitting the buffer state report for the new data to the selected at least one eNB; receiving, from at least one eNB among the first eNB and the second eNB, a resource allocated by the at least one eNB as a response to the buffer state report; and transmitting the new data using the allocated resource.

Dependent claims

A method of reporting a buffer status by a user equipment (UE) configured with two cell groups in a communication system, the method comprising:

in case that new data is generated, triggering a buffer status report of the new data based on an amount of data stored in a buffer of the UE and a threshold value;
transmitting the triggered buffer status report to at least one cell group of two cell groups based on the threshold value and an amount of data available for transmission;
receiving a resource from at least one cell group in response to the triggered buffer status report;
and
transmitting the new data using the received resource,
wherein the two cell groups comprises a master cell group (MCG) and a secondary cell group (SCG).
