Abstract: Certain aspects of the present disclosure provide techniques for uplink control information (UCI) transmission for overlapping physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) resource assignments with repetition. A method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving scheduling to transmit on the PUSCH in a first one or more slots associated with a first number of repetitions and scheduling to transmit on the PUCCH in a second one or more slots associated with a second number of repetitions. The scheduled transmissions overlap in at least one slot. The method includes determining which channel to transmit UCI on and which channel to drop for each of the first and second one or more slots. The method includes transmitting or dropping the UCI in the first and second one or more slots in accordance with the determination.

Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation, which can be used for stand-alone/in-band/guard-band deployment. An example method is provided for operations which may be performed by a base station (BS). The example method generally includes generating a primary synchronization signal (PSS) utilizing a first code sequence and a cover code applied to the first code sequence over a first number of symbols within one or more subframes, generating a secondary synchronization signal (SSS) based on a second code sequence over a second number of symbols within one or more subframes, and transmitting the PSS and the SSS in the first and second subframes to a first type of a user equipment (UE) that communicates on one or more narrowband regions of wider system bandwidth.

Abstract: Methods and apparatuses are disclosed for multiplexing uplink control information and uplink user data in the same uplink slot. A scheduling entity may use a unified rule to map uplink control information (UCI) in a distributed fashion according to a predetermined step size on each orthogonal frequency division multiplexing (OFDM) symbol regardless of UCI types. The scheduling entity may use a unified rule to partition the UCI into two parts when frequency hopping is enabled, and use the same unified rule to map the UCI in each hop.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may map channel state information (CSI) to first resource elements that are distributed in frequency, wherein the first resource elements are in a set of resources allocated on an uplink shared channel; map hybrid automatic repeat request (HARQ) feedback to second resource elements that are distributed in frequency, wherein the second resource elements are in the set of resources; wherein the second resource elements are reserved for the HARQ feedback and are different from the first resource elements; and transmit the CSI and the HARQ feedback on the uplink shared channel in accordance with the mappings. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine information that identifies a resource for transmitting an acknowledgment of a message associated with a random access procedure. The information that identifies the resource may be determined based at least in part on at least one of: a frequency band associated with the random access procedure, a resource associated with at least one message in a sequence of messages associated with the random access procedure, a payload of at least one message in the sequence of messages associated with the random access procedure, or a grant associated with another message in the sequence of messages associated with the random access procedure. In some aspects, the user equipment may transmit the acknowledgment based at least in part on the information that identifies the resource. Numerous other aspects are provided.
