INDICATION OF TDD UPLINK AND DOWNLINK CONFIGURATIONS
Abstract:
Methods and apparatuses for communicating in a cellular communications network, including provision of a user equipment comprising processing circuitry to: receive from a first cell a control signal comprising a physical Time Division Duplex Uplink-Downlink configuration indicator channel (PTCICH); decode from the PTCICH a Time Division Duplex Uplink-Downlink (TDD UL-DL) configuration; and communicate with the first cell having applied the TDD UL-DL configuration in respect of subframes associated with the first cell, wherein: the PTCICH spans less than or equal to 32 Resource Elements. Also user equipment comprising processing circuitry to: receive a control signal from a first cell; decode the control signal received from the first cell thereby to determine a second cell TDD UL-DL configuration; and communicate with the second cell having applied the second cell TDD UL-DL configuration in respect of subframes associated with the second cell.
