Abstract: Wireless communications systems and methods related to on-demand cell coverage extension for broadcast signals are provided. A first wireless communication device communicates, with a second wireless communication device, a first extended cell coverage request. The first wireless communication device communicates, with the second wireless communication device, a first broadcast communication signal in an extended cell coverage mode in response to the first extended cell coverage request. The first broadcast communication signal includes a system information block repeated in at least one of a time domain or a frequency domain.

Abstract: In various aspects, a base station and user equipment (UE) exchange an indication of UE capabilities and a monitoring schedule for the UE to monitor an integer M frequency band partitions for a predetermined signal. The base station performs one or more successful clear carrier assessments (CCAs) on an integer N frequency band partitions of the M frequency band partitions, wherein N

Abstract: Techniques for managing re-contention on a shared communication medium are disclosed. In order to facilitate re-contending for access to the communication medium, an access point may adjust one or more uplink transmission parameters associated with a triggering condition for invoking a contention timer. In addition or as an alternative, the access point may mute transmission on the communication medium during one or more symbol periods designated for transmission. In addition or as an alternative, the access point may configure a timing advance to create a re-contention gap.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for wireless communication are provided. The apparatus may be a base station. The apparatus may transmit an uplink grant to a UE during a first transmit opportunity. The apparatus may signal, during a second transmit opportunity, a grant trigger to the UE to trigger operations associated with the uplink grant that are uncompleted after the first transmit opportunity. The grant trigger may be associated with a set of UEs that includes the UE. The set of UEs may be a subset of the UEs having pending transmissions. The apparatus may instruct the UE regarding whether to keep or discard resources granted by the uplink grant when the UE switches to a different beam during or prior to the second transmit opportunity.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a configuration for enhanced paging to a UE being served by a cell over a shared frequency band. The enhanced paging may include multiple paging intervals for each paging cycle. The UE may enable reception for a paging interval and determine whether the UE receives a downlink transmission. The UE may lengthen a paging interval or enable reception during a second paging interval based in part on determining whether the UE receives a downlink transmission. In some examples, the UE may receive a paging queue status indication indicating that paging information will be transmitted during a paging interval or a later interval, or indicating that no paging information is present at a serving cell.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor for discovery reference signal (DRS) transmissions, physical downlink shared channel (PDSCH) transmissions, or combinations thereof within a DRS transmission window. The UE may attempt to decode DRS or PDSCH transmissions for a subframe based on detection of DRS transmissions, prioritization of DRS transmissions relative to PDSCH transmissions, locations of subframes within a radio frame, overlapping of the DRS transmission window with a paging opportunity, or any combination thereof. In some cases, one or more radio link monitoring (RLM) parameters may be adjusted based on decoding of PDSCH or DRS transmissions.

Abstract: Techniques for managing contention on a shared communication medium are disclosed. Various techniques are provided to facilitate aspects such as reference signaling, downlink medium access, uplink medium access, resource reuse, channel structures, acknowledgment schemes, fairness, acquisition, random access, paging, mobility, inter-operator mitigation, and so on for a frame structure implemented on the shared communication medium.
