METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING TIME DIVISION DUPLEX FRAME CONFIGURATION INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

A method and an apparatus for transmitting and receiving Time Division Duplex (TDD) frame configuration information are disclosed. The base station transmits TDD frame configuration information as system information to a user equipment through a common control channel so as to dynamically change the TDD frame configuration according to uplink and downlink traffic conditions. The base station may deliver the same system information to all user equipments in the cell, removing ambiguity in User Equipment (UE) operations and avoiding interference. In comparison to an existing method of delivering TDD frame configuration information through system information update, the disclosed method enables user equipments to rapidly cope with traffic changes. In addition, user equipments may receive and apply TDD frame configuration information at the same time.

1. A method comprising:
identifying a radio network temporary identifier (RNTI) for time division duplex (TDD) configuration information; obtaining downlink control information (DCI) comprising the TDD configuration information, the TDD configuration information indicating a radio frame structure comprising a downlink subframe, an uplink subframe, and a special subframe; attaching a cyclic redundancy check (CRC) sequence scrambled with the RNTI for the TDD configuration information to the DCI; and transmitting a control signal obtained based on the DCI on a common control channel.
