Original Abstract Submitted

a user equipment (ue) is configured to determine that half-duplex frequency division duplex (hd-fdd) is enabled by a network with which the ue is communicating, identify a collision between a cell-specific downlink reception and a cell-specific uplink transmission and implement a hd-fdd collision handling technique. a ue may also be configured to determine that half-duplex frequency division duplex (hd-fdd) is enabled by a network with which the ue is communicating, perform a first cell-specific uplink transmission at a first time and perform a first cell-specific downlink reception at a second time, wherein a guard period represents a time duration between the first time and the second time during which the ue is not to perform a second different cell-specific uplink transmission or a second different cell-specific downlink reception.
