摘要： Described herein is a procedure for determining multiplexing behavior when multiple physical uplink control channel (PUCCH) and/or physical uplink shared channel (PUSCH) resources of different priority indexes overlap in time. The wireless transmit/receive unit (WTRU) determines a multiplexing indication applicable to a set of resources overlapping in time, at least one condition associated to the multiplexing indication, and multiplexes a subset of the resources based on whether the at least one condition is satisfied. Further described herein are solutions for selecting a grant on which uplink control information (UCI) is multiplexed in the case that no data is available for transmission and the grants are of multiple priority indexes. Also described herein are solutions for reporting accurate power headroom applicable to simultaneous transmission of PUCCH and PUSCH when the PUCCH and PUSCH may be of different priority indexes.

摘要： Methods and apparatuses are described herein for HARQ signaling and communications in wireless networks. For example, a method implemented in a STA comprises receiving a first MU transmission including a first set of HARQ bits, a first set of user data for STAs including the STA, a preamble including information indicating that the MU transmission includes the first set of HARQ bits, and a first set of HARQ Process IDs associated with the first set of HARQ bits; determining a subset of HARQ bits of the first set of HARQ bits; transmitting a response message indicating a reception status of the subset of HARQ bits; and receiving a second MU transmission including a second set of HARQ bits, a second set of user data for the plurality of STAs, and a second set of HARQ Process IDs associated with the second set of HARQ bits.

摘要： Devices, methods, and/or systems for broadcasting in a wireless local area network (WLAN). A STA receives a frame from a wireless access point (AP) which includes an indication that an enhanced broadcast service (eBCS) service is ending. The frame may include an end-of-broadcast-service announcement information element, and/or an indication of a time at which the eBCS service is ending. The STA may negotiate with the AP for continuation of the broadcast service if the STA desires to continue receiving the eBCS service beyond the time at which the eBCS service ends. The STA may receive a trigger frame from the AP which triggers a response from the STA indicating that it desires to continue receiving the eBCS service beyond the time at which the eBCS service ends.

摘要： A method of multi-access point (multi-AP) communication performed by a wireless transmit/receive unit (WTRU) comprises: receiving a first trigger frame from a first access point (AP) of a plurality of APs, the first trigger frame comprising first information; receiving a second trigger frame from a second AP of the plurality of APs at a predetermined time duration after receiving the first trigger frame, the second trigger frame also comprising the first information of the first trigger frame; generating a synchronization frame based on the first trigger frame and the second trigger frame, the synchronization frame comprising synchronization information; transmitting the synchronization frame to at least the first AP and the second AP; and receiving a data transmission based on the synchronization information from each of the first AP and the second AP.

摘要： Methods and apparatuses are described herein for adapting clear channel assessment (CCA) thresholds with or without Transmit Power Control (TPC) are disclosed. An IEEE 802.11 station (STA) may dynamically calculate a STA specific transmit power control (TPC) value and a STA specific clear channel assessment (CCA) value based on a target TPC parameter and a target CCA parameter. The target TPC parameter and the target CCA parameter may be received from an IEEE 802.11 cluster head configured to control TPC and CCA for a plurality of STAs associated with the BSS. The target TPC parameter and the target CCA parameter also may be related. The STA may then determine whether a carrier sense multiple access (CSMA) wireless medium of a wireless local area network (WLAN) basic service set (BSS) is occupied or idle based on the STA specific CCA value.
