Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for beam-specific paging in wireless communication systems. An example method generally includes transmitting, to a network entity, an indication of a mobility state of the UE, wherein the indication is transmitted based on a synchronization signal block (SSB) associated with a selected beam direction; and monitoring paging occasions for paging sent using a beam that is quasi-colocated with the selected beam direction associated with the SSB.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a first communication, associated with a first traffic type, or a second communication, associated with a second traffic type, as a selected communication for transmission in an overlapping resource, wherein the first communication and the second communication at least partially overlap in time, and wherein the selection is performed based at least in part on a rule; and transmit the selected communication. Numerous other aspects are provided.

Abstract: Methods and apparatuses described herein provide a physical downlink control channel (PDCCH) candidate hopping function that reduces collisions between PDCCH candidates, particularly between PDCCH candidates associated with reduced capability user equipment (UE). For example, the hopping function may be implemented as part of a PDCCH candidate to control channel element (CCE) function or may be applied separately from the PDCCH candidate to CCE function. The hopping function may reduce persistent collisions between PDCCH candidates by correlating the mapping behavior with a value that changes over time. Some techniques and apparatuses described herein provide signaling for configuration and activation/deactivation/modification of the hopping pattern. Thus, collisions between PDCCH candidates are reduced, thereby conserving computing resources and wireless communication resources. Furthermore, the reduction of collisions may improve performance of UEs with reduced PDCCH capabilities, such as reduced-capability UEs. Numerous other aspects are provided.

Abstract: A user equipment (UE) may receive a first group downlink control information transmission associated with a UE group, where the first group downlink control information transmission may reference a second group downlink control information transmission (e.g., according to a pre-notification indication). The UE may determine a feedback condition for the second group downlink control information transmission and monitor for the second group downlink control information transmission. Alternatively, the UE may receive a second group downlink control information transmission referencing the first group downlink control information transmission (e.g., according to a post-confirmation indication), and the UE may determine a feedback condition for the first group downlink control information transmission. Based on the feedback condition, the UE may transmit feedback information, for example, indicating that the UE did not correctly receive the indicated group downlink control information transmission.

Abstract: Aspects are provided which allow a base station to provide RACH configuration(s) indicating RACH occasions which correspond to wake up occasions of a base station according to a power savings mode of the base station. The base station sends one or more RACH configurations indicating ROs to a UE, and then monitors the ROs associated with the power savings mode. The UE determines the ROs associated with the power savings mode, and sends a wake up signal to the base station in at least one of the determined ROs. The base station obtains the wake up signal from the UE in at least one of the monitored ROs. Here, the wake up signal comprises a RACH message. As a result, network power consumption may be optimized through designed configurations which allow a UE to wake up a sleeping base station via a RACH message.

Abstract: Methods, systems, and devices for wireless communications are described that relate to a two-step random access procedure. Generally, the described techniques allow different configurations for a first message of a random access procedure depending on a connected-state of the user equipment (UE) performing the random access procedure. A base station may transmit configuration information to the UE and the UE may use the configuration information to determine resources, coding, block size, or other factors for transmitting the first message based on the radio resource control (RRC) connected state of the UE. The UE may then monitor for a random access response from the base station based on the first message from the UE.

Abstract: Systems and methods related to UL communications in a wireless network are provided. A UE receives an indication of a plurality of TXOPs for a RACH procedure from a BS. In an embodiment, the UE starts a timer after either successfully transmitting a random access message to the BS or failing to succeed in any of the TXOPs. In another embodiment, the UE starts the timer at a pre-agreed time after one of the TXOPs, regardless of whether the random access message has been successfully transmitted yet or not. In another embodiment, the UE receives as part of a RACH response an indication of whether the RACH response is split into multiple parts. If the UE does not locate an identifier corresponding to the UE in the RACH response, the UE checks for the indication and, if present, listen for the next RACH response identified from the indication.

Abstract: Certain aspects of the present disclosure provide techniques for paging early indication (PEI) configuration and monitoring procedures. In particular, the present disclosure provides techniques for configuring a user equipment (UE) for PEI monitoring. A method that may be performed by a network entity generally includes transmitting, to the UE, a configuration for paging early indication (PEI) occasions for the UE to monitor and transmitting, in at least one of the PEI occasions, a physical downlink control channel (PDCCH) with a PEI that indicates, for multiple paging occasions (POs), whether paging messages are scheduled for the UE in the multiple POs.

Abstract: Methods, systems, and devices for dynamically configuring connected discontinuous reception (C-DRX) configurations supporting network power modes are described. In some examples, a user equipment (UE) may receive a first control signaling configuring the UE with multiple C-DRX configurations, each C-DRX configuration of the multiple C-DRX configurations corresponding to a respective network power mode. In some examples, the UE may receive a second control signaling including an identifier indicating a C-DRX configuration, of the multiple C-DRX configurations, corresponding to a first network power mode (e.g., an enhanced network power savings mode) at a base station, where the first network power mode may indicated a set of features active at the base station. The UE may communicate with the base station in accordance with the indicated C-DRX configuration and based on the first network power mode.
