Abstract: Methods and apparatus for efficient transmission of data by half-duplex transceivers in satellite communication systems are provided. Time reference for the return link is skewed or time-lagged relative to the time reference for the forward link to reduce the amount of guard time required to separate return link transmission from forward link reception by the half-duplex transceiver of a user terminal. The guard time is determined based on a maximum differential round-trip propagation delay and transition times of the half-duplexer transceiver to switch between transmit and receive modes. In a satellite communication system in which a large number of active user terminals are present in a beam coverage, random time offsets are applied to spread approximately equal traffic loads across the time offsets.
Abstract translation: 提供了卫星通信系统中半双工收发器有效传输数据的方法和装置。 返回链路的时间参考相对于前向链路的时间参考是偏斜的或时间滞后的，以减少用户终端的半双工收发器将返回链路传输与前向链路接收分开所需的保护时间量。 保护时间是基于半双工器收发器在发射和接收模式之间切换的最大差分往返传播延迟和转换时间来确定的。 在波束覆盖中存在大量活动用户终端的卫星通信系统中，随机时间偏移被应用以跨越时间偏移扩展近似相等的业务负载。

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit information associated with one or more uplink transmissions performed by the UE within an L-band. The UE may receive, after transmitting the information, an adjusted frequency domain resource allocation that indicates an adjusted frequency range to be used by the UE for performing one or more other uplink transmissions. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for user equipment (UE) positioning using one or more intelligent reflecting surfaces (IRSs). A method that may be performed by a UE includes for each IRS of the one or more IRSs: identifying a first IRS reflection center, measuring a first impulse response from the IRS to obtain a first measured impulse response representation, determining a first impulse response for a first ray reflected from the first IRS reflection center of the IRS, estimating a first position of the UE based on, at least, the first IRS reflection centers for each of the one or more IRSs and the first impulse responses for each of the one or more IRSs, and estimating a second position of the UE in an iterative manner until one or more conditions are satisfied.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, an indication of a subset of tracking reference signal (TRS) resource sets from a plurality of TRS resource sets. The UE may receive, from the network node, a TRS availability indication bitmap that indicates an availability of a TRS associated with the subset of TRS resource sets. The UE may determine that the TRS is available based at least in part on the TRS availability indication bitmap. The UE may receive, from the network node, the TRS based at least in part on the TRS availability indication bitmap indicating that the TRS is available. Numerous other aspects are described.
