PARTIAL SUBFRAME TRANSMISSION TECHNIQUES IN SHARED RADIO FREQUENCY SPECTRUM

摘要

Techniques provide for identification of a starting location for a transmission that provides a relatively short time period between completion of a successful contention-based access procedure (e.g., a listen before talk (LBT) procedure) and transmission of data between a base station and a user equipment (UE). In the event that an LBT procedure is successfully completed after the start of a subframe, an indication of a transmission may be transmitted at one of a number of predetermined points within the subframe time duration. In some cases, two or more different partial subframe durations may be configured, and one or more different partial subframes may be used for transmissions until the start of a subsequent subframe. An uplink trigger may be transmitted in a partial subframe to indicate one or more of a starting point of the uplink wireless transmission or an ending point of the uplink wireless transmission.
