Abstract: A base-station (BS) receiving a random access request from user equipment (a UE), followed by a connection request. The connection request contains UE identity information which may have one of multiple formats depending on whether the access request and/or the connection request indicate that the UE is operating as a bandwidth-limited (BL) UE, an enhanced coverage (CE) UE, or a UE that operates in neither the BL mode nor the CE mode. In the BL mode, the UE may transmit a truncated identifier that is sufficient for the BS to retrieve capability information for the UE prior to transmitting a resource grant to the UE. The BS may then configure the UE and BS to using a radio configuration optimized for the UE's capabilities and transmit the resource grant in accordance with the optimized configuration.

Abstract: Methods, systems, and devices for wireless communications are described in which UEs may communicate with satellites and base stations or gateways in a non-terrestrial network (NTN). Due to the large distances between transmitting devices and receiving devices in a NTN, timing adjustments to account for propagation delay communications links via a satellite may include a propagation delay between a UE and a satellite, a propagation delay between a base station and a satellite, as well as a variation in the propagation delays due to movement of the satellite. In accordance with various techniques discussed herein, a UE may account for variation in propagation delay, in addition to determined propagation delay, when determining an uplink timing for uplink communications via a satellite.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a radio resource control (RRC) reconfiguration message from a base station including a configuration for communicating with the base station, and the base station may transmit an RRC reconfiguration complete message to the base station (e.g., in response to the RRC reconfiguration message). The UE may then apply the configuration in the RRC reconfiguration message for communicating with the base station after transmitting the RRC reconfiguration complete message. That is, the UE may delay application of the configuration in the RRC reconfiguration message until after the UE transmits the RRC reconfiguration complete message. Using these techniques, ambiguity between the base station and the UE on when the configuration is applied by the UE may be minimized, resulting in improved throughput and reduced latency in a wireless communications system.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine an inactivity timer associated with a first set of one or more beams used for communicating with a network entity associated with a satellite has expired. The UE may identify location information corresponding to the location of the UE with respect to the network entity. The UE may identify beam geometry information for one or more beams associated with the network entity. For example, the UE may receive the beam geometry information from the network entity. The UE may process the location information and the beam geometry information to identify a second set of one or more beams, the second set different than the first set. The UE and the network entity may communicate according to the second set of one or more beams.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a position (e.g., a global navigation satellite system (GNSS)) position of the UE based on a relative position of the UE to another UE. For example, a first UE may determine (e.g., calculate, receive) a relative position of the first UE to a second UE that is selected from a set of UEs including the first UE and the second UE to perform a position acquisition procedure to determine a position of the second UE. The first UE may determine (e.g., calculate, receive) its position based on the relative position of the first UE to the second UE and the position of the second UE and may reset a timer that indicates for the first UE to perform a position acquisition procedure upon expiration of the timer.

Abstract: Methods, systems, and devices for radio link management are described. In a first example, a user equipment (UE) and a base station may employ a procedure for configuring radio link monitoring reference signals (RLM-RS) for multiple bandwidth parts. In a second example, a UE and a base station may employ a beam failure recovery procedure. In a third example, a UE and a base station may employ one or more radio link failure detection procedures. In a fourth example, a UE and a base station may employ a procedure for establishing a new connection after radio link failure. In a fifth example, a UE and a base station may employ a monitoring procedure that involves a single RLM-RS across multiple bandwidth parts.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives one or more downlink signals using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, selects a set of frequency resources for transmitting feedback information associated with the one or more downlink signals, and transmits the feedback information to the base station using the selected set of frequency resources. In some examples, the UE transmits one or more uplink signals to a base station using a first beam associated with a first set of frequency resources, switches from the first beam to a second beam associated with a second set of frequency resources, and determines whether to send a retransmission of the one or more uplink signals based at least in part on switching.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a first physical uplink shared channel (PUSCH) using one or more physical layer (PHY) parameters associated with a first block error rate (BLER) target performance. The UE may receive, from the base station prior to expiration of a round trip timer associated with the first PUSCH, downlink control information (DCI) scheduling a second PUSCH and configuring one or more PHY parameters associated with a second BLER target performance. The UE may transmit, to the base station, the second PUSCH using the PHY parameter(s) associated with the second BLER target performance, wherein the second PUSCH includes a retransmission of the first PUSCH or a new transmission based at least in part on a hybrid automatic repeat request process indicated in the DCI. Numerous other aspects are described.
