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 communicate with a base station in a wireless communications system. The UE may perform a random access procedure to communicate with the base station. The base station may configure the UE with different sets of preamble parameters for different types of UEs. The UE may generate a random access preamble based on the sets of preamble parameters according to the type of the UE. The base station may indicate a location of the base station to the UE. The UE may identify a location of the UE. The UE may determine a pre-compensation timing based on a distance from the two locations. The UE and the base station may transmit subsequent communication according to the random access preamble, the pre-compensation timing, or any combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network entity may pseudo-randomly generate frequency hopping indexes to support secure communication of sounding reference signals (SRSs). For example, the UE may securely obtain a key associated with communication a set of SRSs via respective portions of system bandwidth for communicating with the network entity. The UE and the network entity may generate a set of frequency hopping indexes using the key. The set of frequency hopping indexes may correspond to the set of SRSs, and each frequency hopping index may indicate a respective portion of the system bandwidth for communication of a corresponding SRS. The UE and the network entity may communicate the set of SRSs in accordance with the set of frequency hopping indexes.

Abstract: Aspects of the disclosure relate to a method of operating a user equipment (UE) for wireless communication with a network. In some aspects, the UE obtains a medium access control (MAC) control element (CE) from a network. The MAC CE may be configured to indicate any one of a plurality of state transition actions for a secondary cell. The UE transitions to a secondary cell dormant state when a state transition action indicated by the MAC CE includes a transition to the secondary cell dormant state. The UE operates in the secondary cell dormant state.

Abstract: An apparatus may be configured to communicate at least one pilot signal with another apparatus according to a first configuration, at least one of a lower frequency density or a higher time density being indicated by the first configuration than a second configuration for a type of pilot signal that includes the at least one pilot signal. The apparatus may be further configured to communicate with the other apparatus based on the at least one pilot signal. Another apparatus may be configured to receive, from a base station, spatial relationship information or transmission configuration indicator (TCI) state information corresponding to a directional beam at the UE for communication on a channel. The apparatus may be further configured to apply the directional beam for communication with the base station on another channel in a sub-6 gigahertz (GHz) frequency band.

Abstract: Methods, systems, and devices for wireless communications are described in which repetitions of communications may be configured for multi-transport block (TB) communications. A UE may determine that an acknowledgment of one or more initial repetitions of one or more TBs is received, and may cancel one or more subsequent repetitions of the acknowledged TB(s). The acknowledgment of the one or more initial repetitions may be provided by a base station in a new resource grant that provides an implicit acknowledgment of one or more TBs. In cases where multiple different TBs may be associated with the prior resource grant, the UE can determine to drop one or more repetitions after an implicit acknowledgment of a TB based on whether the resource grants are for a single TB or are for multiple TBs.

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 wireless communications are described. Generally, the described techniques provide for efficiently retransmitting radio link control (RLC) protocol data units (PDUs) to one or more UEs. When a user equipment (UE) fails to receive or decode an RLC PDU transmitted by a base station, the UE may transmit a status PDU to the base station indicating that the UE failed to receive or decode the RLC PDU. The base station may receive the status PDU from the UE, and the base station may generate a repair PDU that includes redundant bits of the lost PDU (e.g., the PDU that the UE failed to receive or decode). The base station may then transmit the repair PDU to the UE, and the UE may use the redundant bits in the repair PDU (e.g., in combination with buffered PDUs) to attempt to correctly decode the lost PDU.
