Abstract: Methods and apparatus for communicating in a wireless network including apparatus comprising transceiver circuitry to send and receive data in a plurality of time periods, defined by a time division duplex (TDD) time grid, to another entity, the plurality of time periods corresponding to a plurality of orthogonal frequency division multiplexing (OFDM) symbols and the transceiver circuitry being operable to switch from receive mode to transmit mode and/or from transmit mode to receive mode according to a flexible uplink and downlink allocation of the plurality of time periods; and baseband circuitry coupled to the transceiver circuitry to control the transceiver circuitry to switch during a switching interval embedded within a time period corresponding to an OFDM symbol of the plurality of OFDM symbols.
