Abstract: Aspects of the present disclosure provide techniques configuring half duplex UEs (HD-UEs) to implement supplementary downlink (SDL) in band combination that may be in same or different frequency range designations (e.g., FR1 or FR2). Particularly, in order to compensate for the loss of downlink coverage and improve load balancing, aspects of the present disclosure configure the UE to perform random-access channel (RACH), a procedure that is a shared channel used by wireless terminals to access the mobile network, on the anchor carrier in time division duplex (TDD) band and after initial access, the UE may be configured to switch to SDL to receive subsequent downlink signals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a downlink control information (DCI) message associated with scheduling transmissions for the UE on a plurality of component carriers. The UE may determine, for at least a first component carrier of the plurality of component carriers, that a frequency resource allocation field of the DCI message comprises an indication of a value that is invalid for frequency resource allocation on the first component carrier. The UE may determine, based at least in part on the invalid indication and using a subset of fields of the DCI message corresponding to the first component carrier, that one or more component carriers of the plurality of component carriers are dormant.

Abstract: Certain aspects of the present disclosure provide techniques for determination, selection, configuration, and/or indication of resource allocation patterns for scheduling services, such as reliable low-latency services (e.g., ultra-reliable low latency communications (URLLC)) and other services in a wireless network, such as new radio (NR) (e.g., a 5G network). A method of wireless communication by a user equipment (UE) is provided. The method generally includes determining a resource allocation pattern that defines resources, from a plurality of configured resource allocation patterns, wherein at least one of the plurality of configured resource allocation patterns comprises a plurality of resource elements with at least a first resource element associated with a first resource allocation restriction and at least a second resource element associated with a second resource allocation restriction and communicating based on the determined resource allocation pattern.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, configuration information related to a random access procedure. For example, in some aspects, the configuration information may include a physical random access channel mask configuration based at least in part on a random access occasion density in a time and frequency domain in a cell served by the base station, a random access response configuration based at least in part on an indication transmitted from the UE to the base station, and/or the like. Accordingly, the UE may perform the random access procedure based at least in part on the configuration information, which may be indicated to the UE in system information, radio resource control signaling, and/or the like. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for port selection for channel state feedback with analog feedforward. A method that may be performed by a user equipment (UE) includes selecting one or more channel state information reference signals (CSI-RS) ports, of a plurality of CSI-RS ports, for the UE to report CSI. The port selection includes selecting any of the plurality of CSI-RS ports for selecting CSI-RS based on a grouping of the plurality of CSI-RS ports. The UE determines a precoding matrix indicator (PMI) formed by a linear combination of the one or more selected CSI-RS ports. The UE computes at least wideband linear combination coefficients for the selected CSI-RS ports. The UE provides the selected one or more CSI-RS ports and the computed wideband linear combination coefficients to a base station (BS) in a CSI report.

Abstract: Wireless communications systems and methods related to acknowledgement/negative-acknowledgement (ACK/NACK) feedback operations for multicast communications are provided. A first user equipment (UE) receives, from a base station (BS), a multicast feedback configuration indicating a first resource configuration for a negative-acknowledgement (NACK) feedback mode; and a second resource configuration for an acknowledgement/negative-acknowledgement (ACK/NACK) feedback mode. The first UE receives, from the BS, a first multicast communication. The first UE transmits, to the BS, a NACK feedback for the first multicast communication based on the first resource configuration. The first UE receives, from the BS, a second multicast communication. The first UE transmits, to the BS, an ACK feedback or a NACK feedback for the second multicast communication based on the second resource configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify a slot format configuration, such as a time division duplex (TDD) slot format configuration, and one or more downlink repetition configurations corresponding to a number of downlink repetitions for a user equipment (UE). The base station may transmit the configurations to the UE. The UE may determine that the number of downlink repetitions and the configured slot format satisfy, or fail to satisfy, a validation rule for monitoring the number of downlink repetitions. The UE may monitor, or refrain from monitoring, the number of repetitions based on whether the validation rule is satisfied.
