摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may receive an indication that a transmission of first data is to be modified and that second data is to be transmitted in place of a portion of the transmission of the first data; and identify a single time at which the transmission of the first data is to be canceled and transmission of the second data can begin, based at least in part on capabilities of the UE. Numerous other aspects are provided.

摘要： 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.

摘要： 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.

摘要： Detecting local cell identifier collision by a base station may be achieved by receiving, at a first base station from a user device, a dedicated identifier associated with a second base station. The dedicated identifier may include or otherwise map to a user device identifier associated with the second base station and a local cell identifier associated with the second base station. Based on the dedicated identifier, it may be determined, at the first base station, that there is a local cell identifier collision between the first base station and the second base station.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, a bitmap that includes a bit sequence to indicate a synchronization signal block (SSB) transmission pattern. The UE may perform rate matching around one or more candidate SSB positions in an initial portion of a window in which SSB transmission is expected, based at least in part on the bitmap, a first parameter indicating a quantity of initial candidate SSB positions in the window subject to rate matching, and a second parameter indicating a quantity of initial bits in the bit sequence that define the SSB transmission pattern. Numerous other aspects are provided.

摘要： Scheduling around frame based equipment (FBE) idle periods reduces the flexibility of scheduling and partitioning. This leads to a latency caused by waiting for the next downlink scheduling opportunity and skipping over unused uplink scheduling slots. According to certain aspects, to reduce overhead caused by idle time and ensure full downlink scheduling, a base station (BS) alternates between idle periods and channel occupancy time every fixed frame period with one or more other synchronized BSs, between components carriers of the BS, or both. Thus, a BS can always schedule downlink on a carrier during an idle period scheduled for a different BS and/or a different carrier.

摘要： Apparatus and methods of wireless communications are described for determining one or more bands (e.g., guard bands in wireless local area networks (WLANs)) in unused portions of an unlicensed spectrum, positioning one or more carriers for cellular communication (e.g., long term evolution (LTE) or LTE advanced communication) in the one or more bands, and performing the cellular communication over the unlicensed spectrum using the one or more carriers. In some non-limiting example aspects, the cellular communication may be in a standalone mode and the one or more carriers may include a primary component carrier (PCC) that is positioned in a Wi-Fi guard band. In these non-limiting example aspects, the apparatus and methods may further include allocating one or more secondary component carriers (SCCs) in Wi-Fi guard bands or in Wi-Fi channels, where the one or more SCCs are opportunistically tuned or turned ON/OFF based on cell loading or backhaul constraints.
