Abstract: Certain aspects of the present disclosure provide techniques for a UE to select a public land mobile network (PLMN). In general, the present disclosure provides methods for PLMN scanning and selection of a PLMN with discontinuous coverage. In certain aspects, a UE may perform a PLMN scan according to a first schedule when a preferred PLMN of the UE is associated with discontinuous coverage (DC) and perform the PLMN scan according to a second schedule when the preferred PLMN of the UE is not associated with DC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may cause a first transmission reception point (TRP) to transmit a first communication using a first time value derived from a first transmission configuration indicator (TCI) state including a set of first quasi co-location (QCL) parameters of the first TRP. The network entity may cause a second TRP to transmit a second communication using a timing pre-compensation value relative to the first time value. Numerous other aspects are described.

Abstract: A method for wireless communication by a user equipment (UE) includes modulating a symbol stream onto at least one subcarrier to generate an uplink signal in a frequency domain for transmitting to a receiver in a non-terrestrial network. The method also includes applying an amount of phase rotation to the at least one subcarrier in the frequency domain. The method further includes transforming the uplink signal from the frequency domain into a time domain uplink signal. The method includes transmitting the time domain uplink signal to the receiver, after applying the phase rotation to the at least one subcarrier.

Abstract: Systems and techniques are provided for wireless communications. For example, an apparatus (e.g., a user equipment (UE)) may receive a plurality of downlink communications, wherein each downlink communication is associated with a Hybrid Automatic Repeat Request (HARQ) process. The apparatus may determine one or more uplink communications, wherein each uplink communication includes feedback associated with at least one downlink communication of the plurality of downlink communications. The apparatus may transmit the one or more uplink communications based on an uplink communication transmission configuration, wherein the uplink communication transmission configuration is determined based on a type of each downlink communication of the plurality of downlink communications.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) and a network node may determine a configuration that indicates an antenna switching point associated with an uplink communication configured for multiple repetitions. The UE may transmit one or more repetitions of the uplink communication using a first transmit antenna prior to the antenna switching point. The UE may transmit one or more repetitions of the uplink communication using a second transmit antenna after the antenna switching point. The network node may perform channel estimation for the uplink communication based at least in part on the configuration that indicates the antenna switching point. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a group-common physical downlink shared channel (PDSCH), where the group-common PDSCH is repeated for a number of repetitions. Accordingly, the UE may determine this number of repetitions and then monitor for the group-common PDSCH based on the number of repetitions. In some implementations, the group-common PDSCH may include a semi-static repetition scheme, where the number of repetitions is indicated via a group aggregation factor. Additionally or alternatively, the group-common PDSCH may include a dynamic repetition scheme, where the number of repetitions is indicated via a group repetition number. Additionally, the techniques described herein may enable the configuration for the repeated group-common PDSCH to include gaps between each repetition of the group-common PDSCH and for the UE to transmit acknowledgment feedback for the repetitions of the group-common PDSCH.
