Abstract: Methods, systems, and devices for wireless communications are described. A network may manage and configure narrow bandwidth parts (NBWPs) for reduced capability user equipment (UEs) based on data priorities, load conditions, etc. For example, in some cases, a NBWP may be associated with some active time interval (e.g., or a UE may be able to utilize a NBWP for some active time interval). A base station may configure periodic NBWPs (e.g., where NBWPs may be active in time according to some periodicity and start time), semi-persistent NBWPs (e.g., where explicit NBWP activation indications and NBWP deactivation indications may be sent by the base station), aperiodic NBWPs (e.g., where the base station may activate a NBWP for some signaled active time interval), or some combination thereof. Additionally or alternatively, a network may support on-demand NBWP activation, timer (e.g., inactivity timer) based deactivation of NBWPs, etc.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a first random access channel (RACH) message to a base station, and monitor for a second RACH message from the base station in a set of resource candidates that are based at least in part on the transmitted first RACH message absent downlink control information. The set of resource candidates may be outside of a physical downlink control channel. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may determine a phase noise profile and may transmit the phase noise profile to a receiving device. The receiving device may use the phase noise profile and received phase tracking reference signals to more accurately determine phase errors on a wireless channel between the two devices and compensate for the phase noise errors. In examples where the UE transmits the phase noise profile to the base station, the UE may include the phase noise profile in a measurement report or in a radio resource control (RRC) message, among other examples. In examples where the base station transmits the phase noise profile to a UE, the base station may include the phase noise profile in a broadcast message, a unicast message, or an RRC message.

Abstract: Aspects described herein relate to switching waveforms in a waveform switching gap. In an aspect, using a transceiver, a first signal of a first waveform can be communicated in a first time period. In a waveform switching gap, the transceiver can be switched to use a second waveform. Using the transceiver, a second signal of a second waveform can be communicated in a second time period. The waveform switching gap may occur between the first time period and the second time period.

Abstract: Generating, by a user equipment (UE) of a wireless access network, for a set of contention-based random access occasions of a base station of the network, a random number over an interval. For the generated random number meeting a threshold value within the interval, transmitting, by the UE and to the base station, a random access preamble within one of the random access occasions of the set. For the generated random number not meeting the threshold value, attempting, by the UE, contention-based access to the network within a subsequent set of random access occasions of the base station, the subsequent set of random access occasions occurring after the set of contention-based random access occasions of the base station.

Abstract: Certain aspects of the present disclosure provide techniques for blind decoding and channel estimation (BD/CE) limitations and configuration of new radio (NR) physical downlink control channel (PDCCH) repetition. A method that may be performed by a user equipment (UE) includes receiving, from a base station, an indication of at least one blind detection limit for detecting a control channel from a set of blind detection limits and monitoring for the control channel based on the received indication of the at least one blind detection limit for detecting the control channel.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive signaling from a base station that schedules the UE to transmit a second uplink signal using a second spatial relationship following transmission of a first uplink signal using a first spatial relationship. The second uplink signal may be scheduled within a beam switching gap associated with switching from the first spatial relationship to the second spatial relationship. In some examples, the UE may transmit the second uplink signal using the first spatial relationship, rather than switching to using the second spatial relationship. In some examples, the UE may shorten the first uplink signal or the second uplink signal (or both) to accommodate the beam switching gap.

Abstract: Various aspects relate to adjusting communication timing in response to a switch from one feeder link to another feeder link in a non-terrestrial network. For example, when a satellite moves out of the coverage area of a first ground network entity (or if the first ground network entity is turned off), the satellite switches to a second ground network entity. The resulting switch from a first feeder link for the first ground network entity to a second feeder link for the second ground network entity may cause a timing glitch that adversely affects the UEs under the coverage of the satellite. The disclosure relates in some aspects to sending an indication of the switch and/or a common timing adjust command to all of the UEs affected by the feeder link switch.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving a first stage of piggyback downlink control information (DCI). The first stage includes scheduling information for a second stage of piggyback DCI. The method also includes receiving the second stage in accordance with the scheduling information. The second stage includes component DCIs. The first and second stages are separately decoded. A method of wireless communication by a base station includes transmitting a first stage of piggyback DCI. The base station also transmits the second stage in accordance with the scheduling information. The second stage includes component DCIs. The first and second stages are separately coded.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical random access channel (PRACH) preamble configuration that indicates a first preamble format for a first PRACH preamble and a second preamble format for a second PRACH preamble, wherein the first preamble format is different from the second preamble format. The UE may transmit the first PRACH preamble as part of a random access procedure based at least in part on the PRACH preamble configuration, wherein transmitting the first PRACH preamble enables a determination of a symbol boundary offset. The UE may transmit the second PRACH preamble as part of the random access procedure based at least in part on the PRACH preamble configuration, wherein transmitting the second PRACH preamble enables a determination of a symbol timing offset. Numerous other aspects are described.
