Abstract: Techniques pertaining to methods to reduce channel accessing delay for Bluetooth system using listen before talk (LBT) in wireless communications are described. An apparatus performs LBT on a channel and, based on a result of the LBT, the apparatus transmits on the channel responsive to the channel being deemed unoccupied. In performing the LBT, the apparatus performs the LBT with at least one of: (a) dynamic transmit (Tx) power control (TPC) with an adaptive energy detection (ED) threshold; (b) an extended clear channel assessment (CCA) time; and (c) the extended CCA time with a multi-block format of transmission.

Abstract: A station (STA) for communicating with an Access Point (AP) in a wireless communication system is provided. The STA includes a wireless transceiver and a processor. The wireless transceiver performs wireless transmission and reception to and from the AP. The processor receives allocation information indicating a first user block for the STA in a first RU of an MU-PPDU from the AP via the wireless transceiver, and the first RU includes multiple user blocks allocated for different STAs. Also, the processor sends Uplink (UL) data or receives Downlink (DL) data in the first user block to or from the AP via the wireless transceiver according to the allocation information.

Abstract: A wireless communications method includes: obtaining a plurality of stream inputs, wherein the stream inputs include a first stream input complying with a first packet format and a second stream input complying with a second packet format, and the second packet format is different from the first packet format; applying pre-coding to the stream inputs to generate a plurality of pre-coded stream outputs, respectively; and performing wireless transmission upon the pre-coded stream outputs, wherein downlink Multi-User Multiple-Input Multiple-Output (MU-MIMO) transmission is involved in the wireless transmission of the pre-coded stream outputs.
