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: Methods, systems, and devices for reducing latency for closed loop sidelink communications for non-terrestrial networks (NTNs) are described. In some examples, a first user equipment (UE) may transmit, to a network entity, a message requesting an allocation of sidelink resources for the first UE and an allocation of sidelink resources for a second UE. The first UE may receive, from the network entity in response to the request message, an indication of a first set of sidelink resources for the first UE. In some examples, the first UE may transmit one or more data messages to the second UE, including an indication of a second set of sidelink resources, an indication that the network entity may directly allocate the second set of sidelink resources, or both. In some example, the first UE may receive one or more data messages from the second UE on the second set of sidelink resources.

Abstract: A node including an RU and a control entity is disclosed. The node may receive, from a base station at a control entity of the node, an indication of at least one obstruction for communication via at least one reflective surface. The indication may indicate to the control entity to utilize an RU of the node and the at least one reflective surface for communication. The node may configure, upon receiving the indication of the at least one obstruction, the RU and the at least one reflective surface for communication with the base station. The node may forward communication received from, or forward communication to, the base station via the RU and the at least one reflective surface based on the at least one obstruction for communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration that defines a quantity of additional guard resource elements (REs) in a frequency domain between different frequency division multiplexed demodulation reference signal (DMRS) code division multiplexing (CDM) groups. The additional guard REs in the frequency domain may not be associated with signal transmissions. The UE may perform a channel estimation based at least in part on the quantity of additional guard REs in the frequency domain between the different frequency division multiplexed DMRS CDM groups. Numerous other aspects are described.

Abstract: A UE, as a part of a RACH communication procedure, may transmit a first sequence within a first set of resources having a first SCS and a second sequence within a second set of resources having a second SCS greater than the first SCS. The second sequence is transmitted with a cyclic prefix greater than inverse of the first SCS divided by a sequence length of the first sequence. The first sequence is a first PRACH preamble. The second sequence may be a second PRACH preamble, an SRS sequence, or DMRS. The UE may repeat the transmission of the first sequence for a first number of times and repeat the transmission of the second sequence for a second number of times independent of the first number.
