Abstract
Embodiments of the present invention relate to a communication method and a device in a time division duplexing system. The communication method in a time division duplexing system includes: notifying a user equipment of an uplink-downlink configuration of a radio frame; specifying a part of downlink subframes corresponding to the uplink-downlink configuration of the radio frame as MBSFN subframes; and sending first information to the user equipment, where the first information is used to indicate that multicast areas of the MBSFN subframes are used for uplink communication or downlink communication.
Claims14
A non-transitory computer readable medium storing instructions codes for a base station communication in a time division duplexing system, which when executed by the base station, cause the base station to perform:
- notifying a user equipment of an uplink-downlink configuration of a radio frame;
- sending configuration information to the user equipment to specify a part of downlink subframes corresponding to the uplink-downlink configuration of the radio frame as multicast broadcast single frequency network MBSFN subframes;
- and
- sending first information to the user equipment, wherein the first information is used to indicate that multicast areas of the MBSFN subframes are used for uplink communication or downlink communication.
A non-transitory computer readable medium storing instructions codes for a base station communication in a time division duplexing system, which when executed by the base station, cause the base station to perform:
- notifying a user equipment of an uplink-downlink configuration of a radio frame;
- sending configuration information to the user equipment to specify a part of downlink subframes corresponding to the uplink-downlink configuration of the radio frame as multicast broadcast single frequency network MBSFN subframes;
- and
- sending first information to the user equipment, wherein the first information is used to indicate that multicast areas of the MBSFN subframes are used for uplink communication or downlink communication,
- wherein the notifying the user equipment of the uplink-downlink configuration of the radio frame and the sending configuration information to the user equipment to specify a part of downlink subframes corresponding to uplink-downlink configuration of the radio frame as MBSFN subframes, specifically comprise:
- notifying the user equipment in a Long Term Evolution or Long Term Evolution Advanced Time Division Duplexing LTE/LTE-A TDD system of uplink-downlink configuration 2 of the radio frame;
- and specifying at least one subframe of subframes 3, 4, 8, and 9 in uplink-downlink configuration 2 as an MBSFN subframe.
A non-transitory computer readable medium storing instructions codes for user equipment communication in a time division duplexing system, which when executed by the user equipment, cause the user equipment to perform:
- receiving an uplink-downlink configuration of a radio frame sent by a base station;
- receiving configuration information that is sent by the base station and specifies a part of downlink subframes corresponding to the uplink-downlink configuration of the radio frame as MBSFN subframes;
- and
- receiving first information sent by the base station, wherein the first information is used to indicate that multicast areas of the MBSFN subframes are used for uplink communication or downlink communication.
