The radio frame configuration circuitry uses control circuitry to select between a plurality of different time-division duplex, TDD, configurations for a radio frame having slots with a configured duration. Transceiver circuitry performs TDD communications based on selections made by the control circuitry such that an average periodicity of switching between transmission of information and reception of information during the TDD communication is the same despite switching between different ones of the plurality of different TDD configurations. The radio frame configuration circuitry can be incorporated in a UE or an eNodeB or a Peer Radio Head. A corresponding method is provided.

Abstract: Disclosed herein is an apparatus of a user equipment (UE) configured to communicate with an evolved Node B (eNB). The UE may include memory and processing circuitry coupled to the memory. The processing circuitry may be configured to decode control information received on one or more channels of unlicensed spectrum. The control information includes indication that a grantless uplink (UL) transmission is allowed without a prior UL grant. The processing circuitry is further configured to perform a listen-before-talk (LBT) procedure on the one or more channels of the unlicensed spectrum to determine if one of the channels is available. Upon determining the channel is available, the processing circuitry can encode UL control information and data for transmission using the grantless UL transmission. The grantless uplink transmission is an unscheduled transmission, performed on the channel without an UL grant.
