Abstract: A new design for physical downlink control channel (PDCCH) is proposed for the next generation 5G new radio systems. A UE receives the configuration of a default control resource set (CORESET) in MIB/SIB from its serving base station. The default CORESET contains both common search space and UE-specific search space for candidate PDCCH transmission. A PDCCH in a default CORESET is mapped to physical resource in a distributed or localized manner. Specifically, various REG-to-CCE mapping rules are proposed to improve frequency diversity gain, or frequency selectivity gain, or to reduce latency of PDCCH processing. Further, to facilitate analog beamforming in mmWave systems, the default CORESET is transmitted in a synchronization signal (SS) block associated with a corresponding analog beam direction.

Abstract: A method of supporting active bandwidth part (BWP) switching under carrier aggregation (CA) is proposed. To avoid longer switching delay and multiple interruptions in other component carriers (CCs)/cells, the starting time of the later active BWP switching in one cell should fall outside the switching delay of the earlier active BWP switching in another cell. If the later active BWP switching is DCI-based, then the network should schedule the later active BWP switching outside the switching delay of the earlier active BWP switching. If the later active BWP switching is timer-based, then the UE should not perform the later active BWP switching until the earlier active BWP switching is completed.

Abstract: A method of efficient wideband operation for intra-band non-contiguous spectrum using extending bandwidth part (BWP) configuration is proposed. The BWP definition is extended to cluster BWPs to aggregate distributed spectrum blocks within a frequency range (e.g., 200 MHz) by single carrier operation and facilitate UE to filter out the transmission of unknown RAT between any two of the distributed spectrum blocks. In addition, the cluster BWP configuration enables dynamic aggregation of the number and location of the distributed spectrum blocks based on LBT results in unlicensed spectrum. Specifically, the BWP definition is extended to a group of one or multiple radio resource clusters, each of which contains a set of contiguous PRBs in frequency domain within the associated carrier.
