Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine that a signal characteristic of a unicast signal is better than a signal characteristic of a broadcast signal; and/or transmit, based at least in part on the determination, a request for an update to a master information block or a minimum system information block to be provided to the user equipment using the unicast signal. In some aspects, a base station may determine that a signal characteristic of a unicast signal associated with a user equipment (UE) is better than a signal characteristic of a broadcast signal broadcasted by the base station; and/or transmit, based on the determination, an update to a master information block (MIB) or a minimum system information block (MSIB) to the UE using the unicast signal. Numerous other aspects are provided.

Abstract: Discovery and synchronization channels are discussed for user-tracking zones in a cellular network. User-tracking zones reduce the mobility tracking burden on the UE and shift the tracking responsibility to the network. This shift allows for UE and network power savings from reduced searching at the UE as well as through efficient paging area tracking and less broadcast signaling. The various aspects provide channel design for initial synchronization and discovery of the user-tracking zones. A single frequency network (SFN) synchronization channel is provided with at least a reference signal for time synchronization and payload information that may include a zone identifier (ID), formatting for a system information transmission request, and resource allocation for the request. The zone ID may be included in the payload or embedded into the reference signal. Facility is also provided for handling zone nodes of different power classes that allows for maintaining the SFN operations.

Abstract: New radio (NR) power headroom report (PHR) design for millimeter wave (mmWave) deployment is discussed. The power control process for mmWave may include beam-specific periodic PHR reporting and user equipment (UE)-specific event-trigger PHR reporting. The periodic PHR reporting may either provide a single PHR that includes power headroom information for each of the serving beams, or the UE may be configured to measure and report PHR for different beams in different slots. When reporting a single PHR with power headroom information for multiple serving beams, a beam index may be included in the reserved bits of the PHR. For the event-trigger PHR, the PHR reported based on a detected event trigger may provide power headroom information only for the current serving beam, or for all serving beams.

Abstract: A wireless network may provide system information by either a fixed periodic broadcast or broad-beam transmission or in response to a request by a user equipment (UE). The wireless network may broadcast (or broad-beam transmit) a signal that indicates to the UEs within a cell or zone coverage area that system information is to be transmitted on a fixed periodic schedule or in response to a request sent by one or more UEs.

Abstract: Methods, systems, and devices for wireless communications are described that provide for configuration of channel bandwidth that may be specific to a particular user equipment (UE). A UE may be configured with a channel bandwidth that is less than or equal to a channel bandwidth of the serving base station, and may also be different than a channel bandwidth of one or more other UEs that are served by the base station. The base station may signal the UE-specific channel bandwidth in UE-specific signaling, such as UE-specific radio resource control (RRC) signaling.

Abstract: Certain aspects of the present disclosure provide techniques for identifying a mismatch between a user's common search space (CSS) and user-specific search space (USS). A base station (BS) may receive an indication that a user equipment (UE) decoded at least one beamformed signal transmitted by the BS in a USS and did not decode at least one beamformed signal transmitted by the BS in a CSS. The BS may take one or more actions based, at least in part, on the indication. Similarly, a UE may decode at least one beamformed signal transmitted by a BS in a USS, transmit to the BS an indication that the UE decoded the at least one beamformed signal transmitted in the USS and did not decode at least one beamformed signal transmitted by the BS in a CSS, and take one or more actions based, at least in part, on the indication.

According to certain aspects, a method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving a configuration indicating one or more triggers for transmitting on an uplink access channel, wherein the one or more triggers comprise a first indication of mobility of the UE, determining, based at least in part on detection of one of the one or more triggers, to transmit on the uplink access channel, transmitting a signal on the uplink access channel, and receiving, in response to the transmission of the signal on the uplink access channel, a second indication of at least one of: confirmation of reception of the signal or a paging notification.

Abstract: A UE may be operating in a wireless communication network having a UE-centric medium access control layer, and the UE may detect presence of a trigger event to signal a base station of the wireless communication network. The UE may identify one of a plurality of functionalities corresponding to the trigger event, and may generate a chirp signal that includes chirp purpose indicator and a chirp message, wherein the chirp purpose indicator and a format of the chirp message correspond to the identified one of the plurality of functionalities. Accordingly, the UE may transmit the chirp signal having the chirp purpose indicator to the base station, which may provide a chirp response message that includes message contents that relate to the chirp purpose indicator.

Abstract: Systems and techniques are disclosed to separate paging and access cell selection (and use) among available cells based on different paging cell and access cell requirements and specific service availability. A UE selects a first cell that meets paging cell requirements as a paging cell and a second cell that meets service requirements as an access cell. Once the UE selects a paging cell, the UE camps on the paging cell to wait for a paging request or a mobile originated request. The UE can select and camp on the access cell prior to a data need, where latency requirements are strict, or delay access cell selection until there is data to transmit where latency requirements are more lax. The UE may also include measurement information of surrounding cells with a paging response/service request, which a core network uses to speed up establishment of dual connectivity or carrier aggregation.
