Patent Searching and Data


Title:
AVOIDING CALL DROP IN LIMITED UPLINK OR DOWNLINK-CENTRIC SCENARIOS
Document Type and Number:
WIPO Patent Application WO/2019/161524
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an uplink grant identifying a next transmission opportunity. The UE may determine that transmission of a buffer status report (BSR) would interfere with transmission of additional queued data. In some cases, the transmission of BSRs may have precluded transmission of the additional queued data. The UE may determine that a number of prior transmissions in which control data or signaling data was not sent satisfies a threshold. The UE may further transmit a truncated BSR during the next transmission opportunity based at least in part on the threshold being satisfied. The truncated BSR may include buffer information for a highest priority logical channel group or buffer information for the logical channel group that includes the most queued data. The UE may also transmit additional queued data during the next transmission opportunity.
