Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a scheduled entity to communicate within a wireless communication network. In one aspect, the scheduled entity receives a plurality of neighbor cell measurement relaxation mechanisms from a scheduling entity. The scheduled entity determines one or more channel condition parameters and selects one or more of the pluralities of neighbor cell measurement relaxation mechanisms, based on the determined one or more channel condition parameters. The scheduled entity executes measurement of one or more neighbor cells using the selected one or more neighbor cell measurement relaxation mechanisms.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for radio link monitoring reference signal (RLM-RS) determination using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications from a UE generally includes determining resources to monitor for radio link monitoring (RLM) prior to being configured with resources to monitor for RLM after establishing a radio resource control (RRC) connection with a network, and performing RLM based on the determined resources.

Abstract: Certain aspects of the present disclosure provide techniques communicating in a wireless network. In one embodiment, a method includes monitoring for a paging downlink control channel comprising downlink control information, wherein the downlink control information comprises a first short message; processing the first short message; determining if the control information further comprises scheduling information; processing the scheduling information if the downlink control information comprises scheduling information and the UE is not in a connected state; and ignoring the scheduling information if the downlink control information comprises scheduling information and the UE is in a connected state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit a message, to a user equipment (UE), instructing the UE to activate or update a reference signal (RS) corresponding to an uplink communication transmitted by the UE. The base station may communicate with the UE, after a time period, using a beam configuration of the base station that corresponds to a beam configuration of the UE for transmitting the RS, the time period being based at least in part on a determination of whether the UE identified the beam configuration of the base station. Numerous other aspects are provided.

Abstract: The present disclosure provides techniques for addressing switching times of Integrated Access and Backhaul (IAB) child nodes. For example, a parent IAB node may determine a switching time for the child IAB node to switch from transmitting on a backhaul/uplink to a parent node (with transmit power control) to transmitting on an access/downlink to a user equipment (UE) or other child IAB node. The parent IAB node may then configure the IAB child node according to the determined switching time (e.g., by scheduling the IAB child node accordingly or setting one or more timing advance parameters).

Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for determining, by a user equipment (UE), a first time period for an evaluation procedure during communications with a network entity; performing, by the UE, a first set of measurements of a quality of a first set of discovery reference signals during the first time period; and determining, by the UE, whether to initiate a set of actions associated with the evaluation procedure based on the first set of measurements of the quality of the first set of discovery reference signals.

Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for establishing, by a user equipment (UE), a first time period to evaluate one or more quality parameters of one or more reference signals, wherein the first time period is based on at least one of a number of panels of the UE or a number of beams that the UE monitors simultaneously; determining, by the UE, a quality parameter of a beam or a cell based on the one or more quality parameters of the one or more reference signals; and determining, by the UE, whether the one or more quality parameters of the one or more reference signals exceeds a quality threshold.

Abstract: Aspects provide for autonomous adjustment of the uplink and downlink transmission timing in wireless communication networks. A scheduled entity (e.g., a user equipment (UE) or child integrated access backhaul (IAB) node) may observe a change in the downlink reception timing of downlink signals transmitted from a scheduling entity (e.g., a base station or parent IAB node). The scheduled entity may then autonomously adjust its uplink transmission timing to compensate for the change in downlink reception timing. In addition, the scheduled entity may further maintain the same downlink transmission timing irrespective of the change in downlink reception timing.

Abstract: A connection establishment procedure such as a handover or re-establishment procedure including a 2-step random access procedure may be completed within a defined time period. The defined time period may be measured from a handover command or a determination that a user equipment (UE) has lost a connection to a base station. The defined period of time may depend on one or both of a synchronization signal block (SSB) to random access channel (RACH) association period or a SSB to RACH association pattern period. The UE may receive a handover command from a serving cell. The UE may perform a handover in response to receiving the handover command or a re-establishment procedure in response to detecting the lost connection within the defined time period. One or more base stations may reserve resources for the connection establishment procedure during the defined time period.
