Abstract: A method and apparatus for operating a user terminal in a satellite communication system during inter-beam handovers. In some aspects, the user terminal may determine an occurrence of an inter-beam handover for switching communication with a network controller of the satellite communication system from a first beam to a second beam. The user terminal measures a channel quality of the second beam based at least in part on the occurrence of the inter-beam handover, and sends the channel quality measurement to the controller via a reverse-link communication.

Abstract: Disclosed is a method for wireless communication for determining the position of a wireless node. The method comprises receiving a set of reference signals from a set of at least four positioning devices, wherein the positioning devices are not arranged in a single plane. A signal propagation delay of each one of the set of reference signals is determined and a position of each one of the set of positioning devices is obtained. A convex localization problem is solved for the wireless node based at least in part on the determined signal propagation delay of each one of the set of reference signals and the position of each one of the set of positioning devices. The position of the wireless node is determined based at least in part on solving of the convex localization problem.

Abstract: A method of wireless communication, by a user equipment (UE), includes receiving, from a first transmission and reception point (TRP) operating in a first band, assistance information comprising collocation information for both a second TRP operating in a second band and a communication node operating in the first band. The method also includes receiving, from the first TRP, configuration information for one or more reference signals (RSs) associated with the communication node. The method further includes communicating with the second TRP based on one or more features of the second band estimated from the one or more RSs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may release a connection with a first network entity and determine a first virtual coverage area of the UE based on a geographic location of the UE associated with the release of the connection. The UE may obtain a message that includes area information. The area information may be indicative of one or more second virtual coverage areas, which the UE may use in determining whether to monitor for a paging early indication (PEI). Based on the first virtual coverage area and the one or more second virtual coverage areas may monitor for a paging message, such as the PEI or downlink control information (DCI) associated with a paging occasion.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, from a base station, an indication of a time gap value associated with a random access channel (RACH) procedure, wherein the time gap value is based at least in part on a capability of the base station, determine whether a physical RACH (PRACH) occasion associated with the RACH procedure is valid based at least in part on receiving the indication of the time gap value associated with the RACH procedure, and selectively transmit, to the base station, a PRACH transmission in the PRACH occasion based at least in part on determining whether the PRACH occasion is valid. Numerous other aspects are provided.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication for applying resource element (RE) skipping to a symbol where a beam change is to occur. A transmitter and a receiver determine that a beam change is to occur during the symbol. The transmitter allocates bits to a subset of REs for the symbol in a frequency domain allocation. Each RE of the subset is spaced apart by a number of empty REs. The transmitter performs an inverse fast Fourier transform (IFFT) on the REs to generate a time domain signal including a number of repetitions of a transmitted waveform. The receiver receives the time domain signal during at least a portion of the symbol. The receiver performs a fast Fourier transform (FFT) on the time domain signal and determines transmitted bits or a channel from the subset of REs output from the FFT.
