Abstract: The present methods and apparatus relate to wireless communications at either a user equipment (UE) or a network entity in a new radio communication system. The described aspects include receiving, via a communication channel, a scheduling grant from a transmitting wireless device, the scheduling grant including a Resource Indication Value (RIV) corresponding to an allocation of resource blocks (RBs) for communicating on the communication channel. The described aspects further include mapping the RIV to a constrained set of one or more RBs to identify allocated RBs, the constrained set of one or more RBs including a fewer number of RBs than a number of available RBs in a slot or transmission duration. The described aspects further include communicating, with the transmitting wireless device via the communication channel, using the allocated RBs from the constrained set of one or more RBs as signaled by the RIV.

Abstract: In wireless communication systems that support 5G or NR protocols, subframes used for communication may have different numerology options. Numerology options may refer to the characteristics of the subframe such as a tone spacing within each symbol of the subframe, a symbol duration for each symbol of the subframe, a number of symbols in the subframe, etc. A subframe may include a control channel (e.g., the PDCCH) and a data channel (e.g., the PDSCH). In an aspect, the control channel and the data channel within the subframe may have different numerologies. As such, a need exists to signal the numerology of the subframe to users and to determine whether and how to multiplex the control channel and the data channel into the subframe.

Abstract: A physical uplink control channel format is determined based on a determined uplink control information (UCI) payload size. Enhancement of uplink control channel on a 5G physical uplink control channel (xPUCCH) based on UCI payload size can be accomplished by (1) a dropping rule if UCI payload size exceeds the maximum allowable payload size supported by xPUCCH format; (2) a scheduling request (SR) transmission scheme when combined with other UCI information; (3) enhancement on beam refinement reference signal (BRRS) scheduling; and (4) downlink control information (DCI) requests for the transmission of channel state information (CSI) report and beam related information by itself.

Abstract: A wireless communication device (16) signals uplink control information for multiple different downlink carriers to a base station (20) in a wireless communication system (10). The device (16) in this regard intersperses uplink control information known by the base station (20) with uplink control information not known by the base station (20) across one or more information words that comprise uplink control information for multiple different downlink carriers. The device (16) channel encodes the one or more information words to obtain one or more codewords, and then transmits the one or more codewords to the base station (20) as an uplink control information report. The base station (20) correspondingly channel decodes the one or more codewords to obtain the one or more information words.
