Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that schedules an uplink communication in an uplink frequency band. The UE may transmit, at an uplink frequency within the uplink frequency band, the uplink communication with a power that varies over the uplink frequency band based at least in part on a location of the uplink frequency relative to a downlink frequency band associated with the UE. Numerous other aspects are provided.

A data reception device comprises: a first data input for receiving a first data signal and a clock input for receiving a clock signal; and a stability detection circuit adapted to generate: a first error signal indicating when a data transition of the first data signal occurs during a first period at least partially before a first significant clock edge of the clock signal; and a second error signal indicating when a data transition of the first data signal occurs during a second period at least partially after the first significant clock edge of the clock signal; and a control circuit configured to generate a control signal for adjusting the sampling time of the first data signal based on said first and second error signals.

Systems and methods are disclosed herein that relate to multiple candidate starting points for a transmit burst in unlicensed spectrum. In some embodiments, a method of operation of a radio access node for performing a transmit burst in an unlicensed spectrum comprises transmitting a transmit burst in an unlicensed spectrum, wherein the transmit burst spans multiple subframes/slots and the transmitting of the transmit burst starts at one of a plurality of candidate starting points defined in at least a first subframe/slot of the transmit burst that occurs after successful completion of a Listen-Before-Talk (LBT) procedure for the transmit burst. In this manner, a radio access node (e.g., an enhanced or evolved Node B (eNB) in Long Term Evolution (LTE)) has flexibility to transmit a downlink transmit burst starting at different starting positions based on LBT outcome.

A communication device that applies an error in an upper layer in addition to error correction in a physical layer is provided. The communication device includes an acquisition unit that acquires control information regarding forward error correction (FEC) of an upper layer and control information regarding FEC of a lower layer, an encoding-decoding unit that performs error correction encoding or decoding of an information sequence in the upper layer according to control information regarding the FEC of the upper layer, and a puncturing processing unit that performs puncturing or depuncturing in the upper layer. The information sequence after FEC encoding of the upper layer is divided into blocks, and puncturing and interleaving are performed in units of blocks.
