Abstract: In an aspect, a slave UE and a master UE each establish an attachment to a core network of a cellular communications system. The slave UE obtains security credentials configured to encrypt and decrypt traffic between the slave UE and the core network. A D2D connection is established between the slave UE and the master UE (e.g., tethering). One or more communication functions are offloaded from the slave UE to the master UE, including at least one communication function with the core network for maintaining the attachment of the slave UE to the core network. Application-layer data is relayed to/from the slave UE over the D2D connection. In an aspect, either the slave UE or the master UE may perform encryption and decryption of control plane signaling using the slave UE's security credentials.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may generate a radio resource control (RRC) message including an indication that a user equipment (UE) is to wake from a power saving state or to reconfigure a cycle associated with the power saving state; and transmit the RRC message toward the UE via a connection of a second cell group to cause the UE to wake from the power saving state or reconfigure the cycle associated with the power saving state. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a frequency associated with a synchronization signal block (SSB) associated with a base station. The UE may generate a security key associated with a handover of the UE based at least in part on the frequency associated with the SSB. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a hybrid automatic repeat request (HARQ) process identifier for a communication between the UE and a base station using a semi-persistent scheduling (SPS) configuration or a configured grant (CG) configuration, wherein the determination of the HARQ process identifier is based at least in part on an offset applied for the determination of the HARQ process identifier; and perform the communication based at least in part on the HARQ process identifier.

Abstract: A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of a downlink beam in uplink control information of a random access message, wherein the downlink beam is different from a default beam corresponding to a preamble of the random access message and a random access occasion in which the random access message is transmitted, or wherein the downlink beam is selected from a set of multiple downlink beams corresponding to the random access occasion. The UE may monitor for at least one of a random access response or a downlink communication subsequent to the random access response using the downlink beam indicated in the uplink control information.

Abstract: The present disclosure relates to technique for facilitating PDCCH monitoring in carrier aggregation for lower power consumption. A UE monitors a physical downlink control channel (PDCCH) on a secondary cell (SCell). The UE stops the PDCCH monitoring on the SCell in response to a monitoring-stoppage event. Then, the UE resumes the PDCCH monitoring on the SCell in response to a monitoring-resumption event. The SCell may remain active during a period between the stopping of the PDCCH monitoring and the resuming of the PDCCH monitoring.
