TERMINAL BUFFER STATE REPORTING (BSR) METHOD, METHOD OF OBTAINING BSR FROM BASE STATION AND CORRESPONDING TERMINAL, BASE STATION AND COMMUNICATION SYSTEM

摘要

FIELD: radio engineering, communication.SUBSTANCE: group of inventions relates to communication and can be used for terminal buffer state reporting (BSR). A terminal includes buffer state report table; at least another extended buffer state report table; a table selector unit configured to select a table from a buffer state report table and an extended buffer state report table; an index determination unit configured to obtain an index from a table in accordance with the amount of data in the terminal buffer; and an index sender configured to send an index to a base station, wherein the table selector unit is configured to select a table in accordance with the indication in signalling for establishing a radio resource control (RRC) connection received from the base station.EFFECT: extending a BSR table for adaptation to a new maximum buffer size.10 cl, 14 dwg
