    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information indicating at least one of a first set of peak reduction tones (PRTs) for uplink communication, or a second set of PRTs for downlink communication, for use in a full-duplex communication mode. The first set of PRTs and the second set of PRTs may share at least one PRT. The UE may transmit, to the base station, or receive, from the base station, at least one signal based at least in part on the at least one of the first set of PRTs or the second set of PRTs. Numerous other aspects are provided.

    Abstract: Aspects of the present disclosure provide techniques for variable spreading factor codes for non-orthogonal multiple access (NOMA). In an exemplary method, a base station assigns, from a first codebook of N short code sequences of length K, a subset of the short code sequences to a number of user equipments (UEs); receives a signal including uplink data or control signals from two or more of the UEs, wherein a first uplink data or control signal is sent using a first subsequence of one of the assigned short code sequences, and a second uplink data or control signal is sent using a second subsequence of one of the assigned short code sequences or using one of the assigned short code sequences; and decodes each uplink data or control signal in the signal based on the assigned short code sequences and subsequences of the assigned the short code sequences.

    Abstract: Control channel decoding can consume a significant amount of power with respect to the device's total power battery lifetime, as well as being a factor in the complexity of device. Aspects of a method, apparatus, and computer-readable medium are presented herein that provide a solution to the problem of control channel decoding complexity and power requirements by improving the manner in which control channels are decoded. An apparatus configures an initial CORESET having a reduced bandwidth corresponding to a bandwidth capability of a first UE type. The reduced bandwidth having a narrower frequency range than a bandwidth capability of a second UE type. The apparatus may configure a first CORESET for a first UE having a first bandwidth capability and a second CORESET for a second UE having a second bandwidth capability. The apparatus transmits control channel(s) in the configured CORESET(s).

    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided that may be configured to receive a downlink control message, to determine a beta offset value for transmitting UCI based at least in part on the downlink control message, and to transmit the UCI on an uplink shared channel interleaved with data based on the determined beta offset value. The apparatus may identify the beta offset from a set of values based on the downlink control message. An apparatus may identify resources allocated for PUSCH and may map UCI to the identified resources for PUSCH in a frequency interleaved manner over a bandwidth of the identified resources. The apparatus may map data to the identified resources in a time-first or frequency-first manner, and may transmit a signal comprising UCI and data on the identified resources of the PUSCH in accordance with the mapping.

    Abstract: Certain aspects of the present disclosure provide techniques for physical uplink control channel (PUCCH) before radio resource control connection setup completion. A by a base station (BS) generally includes transmitting a system information block, to a user equipment (UE), containing system information indicating a resource set of a plurality of predefined resource sets, each containing a plurality of resources. The BS transmits downlink control information on physical downlink control channel associated with a control channel element (CCE) index, to the UE, containing resource indicator (RI) bits to indicate a resource of the plurality of resources of the indicated resource set available for the UE to use for transmitting uplink control information (UCI) in a PUCCH. The BS monitors the indicated resource for the PUCCH transmission. A UE determines the resource based on the SI, RI bits, and CCE index, and transmits UCI in the PUCCH on the determined resource.
