Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may selectively transmit, to a network entity, a request for a dedicated system information block type 1 (SIB1) for a target cell based at least in part a determination of whether an SIB1 request criterion is satisfied for an idle state cell reselection from a source cell to the target cell. The UE may receive, from the network entity, an indication of one or more target cell SIB1 parameters included in the dedicated SIB1 for the target cell, based at least in part on transmitting the request for the dedicated SIB1 for the target cell. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) receiving, from a network node, a message that indicates for the UE to generate a periodic channel state information (CSI) report including refinement information with respect to a previously CSI report. The UE may receive one or more demodulation reference signals (DMRSs) during one or more semi-persistent scheduling (SPS) occasions and generate the CSI report, where the refinement information included in the CSI report is based on measurements of the received one or more DMRSs. The UE may then transmit the CSI report to the network node.

Abstract: An on-demand scheduling request (SR) design is disclosed. Such an on-demand or triggered SR operation provides pre-configuration of user equipments (UEs) with triggered SR resources. Base stations may also configure UEs to monitor for a trigger signal within a bit field of control signaling from the base station. Upon detecting the trigger signal within such bit field, the UEs may use the triggered SR resources for transmitting triggered SR requests. Such use of the triggered SR resources may be in response to UEs detected cancelation of other periodic configured SR resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a first condition of the UE. The UE may perform one or more actions associated with coverage enhancement based at least in part on a measure of similarity between the first condition of the UE and a second condition of the UE associated with a past beam failure event. Numerous other aspects are described.

Abstract: Extension of power efficient paging in a wireless network. In some examples, information is buffered for a time period corresponding to a paging slot, or both the paging slot and at least one adjacent slot. The buffered control information is processed to detect paging downlink control information (DCI) and a tracking reference signal (TRS). Based on the processing, the paging message is scheduled in a physical downlink shared channel (PDSCH) in the paging slot. In some examples, quasi-co-located (QCL) processing may be performed on the TRS and the paging DCI paging message, and a paging message is scheduled, based on the QCL processing, in a physical downlink shared channel (PDSCH) in a same or offset paging slot.

Abstract: Aspects presented herein may enable a remote UE to notify a base station about the availability of a relay UE that is not connected to the base station. In one aspect, a remote UE transmits, to a relay UE, a relay request via sidelink, the relay UE being in an RRC inactive mode. The remote UE receives, from the relay UE via the sidelink, an indication of relay availability in response to the relay request. The remote UE receives, from a base station, a configuration for relay of communication from the base station over the sidelink between the remote UE and the relay UE. The remote UE transmits or receives user data from the base station through the relay UE based on the configuration.

Abstract: Aspects presented herein may enable a base station to transmit information associated with PBCH/MIB and information associated with DCI in a combined block to enhance the initial access procedure for a UE. In one aspect, a base station transmits a combined block comprising a synchronization signal and information scheduling a SIB1 PDSCH. The base station transmits the SIB1 PDSCH based on the information.

Abstract: Methods, systems, and devices for wireless communications are described for block feedback of multiple semi-persistent scheduling (SPS) occasions. Block feedback may be provided based on variable feedback timing values that are associated with one or more SPS occasions. A user equipment (UE) may determine feedback for each of two or more SPS occasions, and transmit a block feedback that indicates the feedback. A separate feedback timing between a SPS occasion and uplink feedback resources may be provided for multiple SPS occasions, which are associated with a single uplink feedback resource. Alternatively, a minimum feedback timing value and a maximum feedback timing value may be configured for a particular uplink resource, and block feedback for multiple SPS occasions within the minimum and maximum feedback timing values may be reported in the uplink feedback resource.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting channel state information reference signals (CSI-RS) scheduled by a remaining minimum system information (RMSI) physical downlink control channel (PDCCH) for use by a user equipment (UE) for beam refinement. A method by a user equipment (UE) includes receiving a physical downlink control channel (PDCCH), from a base station (BS), that schedules transmission of a remaining minimum system information (RMSI) and schedules transmission of a channel state information (CSI) reference signal (CSI-RS) by the BS; and processing the CSI-RS.
