    Abstract: Managing the coexistence of multiple different UE types and capabilities in wireless networks is disclosed. In order to handle the various transmission types and available UE capabilities, base stations may coordinate among each other over backhaul communications to schedule identifiable groups of UEs being served for specific sets of resources. The resources may be assigned, and UEs grouped, according to particular transmission types, UE capabilities, or a combination of both. Additional aspects may also provide for signaling to the UE that informs the UE of expected transmission types for given resources. The combined aspects facilitate reducing complexity of UE signal processing for data interference cancellation, signal decoding, and the like.

    Abstract: Estimation of timing errors is disclosed that uses user equipment reference signals (UERSs). A UE models each channel in a user equipment reference signal (UERS) as a channel on an adjacent UERS tone multiplied by a phase ramping term. This phase ramping term is determined using an estimator on the modeled channels. The UE then determines the equivalent timing error by mapping the phase ramping terms into the estimated timing errors in the time domain. In coordinated multipoint (CoMP) systems, the UERS-based timing error may be used to identify an aligned common reference signal (CRS) associated with the network entity transmitting the data. With this determination, the UE may estimate a CRS-based timing error and either substitute the CRS-based timing error for the UERS-based timing error or calculate a further average timing error based on both the CRS-based and UERS-based timing errors.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate an uplink control information (UCI) message including a scheduling request bit multiplexed with a first UCI bit and a second UCI bit, including: selecting a set of sequences, of a set of candidate sets of sequences, to use for multiplexing the first UCI bit and the second UCI bit, the selection of the set of sequences indicating the scheduling request bit, and multiplexing the first UCI bit and the second UCI bit based at least in part on the set of sequences. The UE may transmit the UCI message. Numerous other aspects are described.

    Abstract: A method for wireless communication by a UE includes receiving, from a base station, DCI indicating both a semi-persistent schedule for PDSCH occasions within a transmission window and a first quantity of a first group of empty PDSCH occasions. The PDSCH occasions may include the first group of empty PDSCH occasions and a second group of non-empty PDSCH occasions. The method also includes receiving, from the base station, downlink data transmissions within the transmission window based on the semi-persistent schedule. The method further includes transmitting, to the base station, a feedback message indicating a second quantity of either a first group of NACKs associated with the first group of empty PDSCH occasions or a second group of NACKs associated with the second group of non-empty PDSCH occasions based on a total quantity of both the first group of NACKs and the second group of NACKs being greater than the first quantity.

    Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. The techniques include a method wireless communication by a user equipment including receiving a first physical downlink control channel (PDCCH) from a first transmission reception point (TRP) and a second PDCCH from a second TRP, wherein the first PDCCH and the second PDCCH include the same downlink control information (DCI), selecting a physical uplink control channel (PUCCH) resource for transmitting hybrid automatic repeated request acknowledgment (HARQ-ACK) feedback based on one of the first PDCCH or the second PDCCH, and transmitting a PUCCH that includes the HARQ-ACK feedback using the selected PUCCH resource.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a payload for inclusion in an uplink transmission. The UE may organize the payload into a code block group (CBG) that includes one or more code blocks (CB). The UE may map each CB of the CBG to a corresponding uplink shared channel resource unit (e.g., a physical uplink shared channel resource unit) of an uplink transmission occasion of the first UE. The uplink transmission occasion may also be shared with one or more additional UEs such that the CBG of the first UE is multiplexed with additional CBGs from the additional UEs. The UE may transmit, to a base station, the uplink transmission including each uplink shared channel resource unit on which the CBG is organized.
