Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information that indicates whether to perform a first random access channel (RACH) procedure for a non-terrestrial network or a second RACH procedure for a terrestrial network, wherein the first RACH procedure is configured to support a larger number of UEs contemporaneously performing a RACH procedure than the second RACH procedure. Responsive to the information indicating that the UE is to perform the first RACH procedure, the UE may perform the first RACH procedure. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described in which a block error rate (BLER) in non-terrestrial network (NTN) communications may be reduced through coverage enhancement techniques. Coverage enhancement techniques may include slot bundling for physical downlink control channel (PDCCH) communications, in which repetitions of a PDCCH may occupy multiple time-frequency locations spanning multiple slots. Such slots can be consecutive or non-consecutive, and in some cases multiple repetitions of the PDCCH may be provided within the same slot. The pattern of the time-frequency locations of repetitions may be periodic or non-periodic. Further, the repetitions can be exact copies, or different redundancy versions of the same encoded DCI. Additionally, repetitions of uplink or downlink shared channel communications, uplink or downlink control channel communication, broadcast channel communications, or any combinations thereof, may be provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radar device may process a transmitted radar signal and a received radar signal to obtain at least one energy level measurement. The radar device may determine that the at least one energy level measurement satisfies a threshold value. The radar device may perform a listen before talk procedure based at least in part on determining that the at least one energy level measurement satisfies the threshold value. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure may reduce number of radar transmissions between a group of wireless devices while still enabling wireless devices with accurate radar measurements on a target object. In one aspect, a first wireless device receives a first radar-detection information from a second wireless device. The first wireless device transmits one or more radar pulses based at least in part on a radar transmission order being based on the first radar-detection information. In another aspect, a UE receives radar-detection information from multiple wireless devices. The UE transmits a radar transmission order to the multiple wireless devices based on the radar-detection information.

Abstract: Various designs for reference signals for beam management (BM) in non-terrestrial networks (NTNs) in 5G systems are discussed. NTN platforms determine to transmit a BM reference signal associated with a beam in an NTN. The BM reference signal is configured to facilitate beam switching at a wireless communication entity, and the beam having a beam bandwidth. The NTN platforms determines a frequency resource for transmitting the BM reference signal, and transmits, to a wireless communication entity, the BM reference signal in the determined frequency resource. The wireless communication entity monitors the frequency resource, receives the BM reference signal associated with the beam in the frequency resource, and manages beam selection based on the received BM reference signal. Other aspects and features are also claimed and described.
