Abstract: A coordinated form of R-TWT SP scheduling taking into account the needs of non-AP STAs in adjacent BSS. A flag in the BSSID field is used to indicate if the AP is represented by the BSSID is a UHR AP.

The protocol for UHR AP and UHR non-AP STAs allows for identifying possible interference with the OBSS, directly rescheduling, or performing negotiation with the UHR AP of the OBSS for scheduling the R-TWT SP.

Abstract: Wireless IEEE 802.11 communication mechanisms are described for a member STA of a R-TWT SP to gain TXOP channel access before the R-TWT SP, which does not need to end before the start time of the R-TWT SP. On trigger based R-TWT SP, the TXOP time is shared to overlap the R-TWT SP; allowing the AP to behave as the TXOP holder for the frame exchange of latency sensitive traffic during the R-TWT SP. Thus, the R-TWT scheduling AP and member STAs of a R-TWT SP can contend for the channel together before the scheduled start time of the R-TWT SP. When one of these STAs gains channel access, it can reserve a TXOP until the scheduled end time of the R-TWT SP, which may extend beyond the normal TXOP limit.

Abstract: The present invention is directed immunoassay methods, which re-use a hapten-immobilized test probe and reagents for quantitating an analyte in different samples, anywhere from about 3 to 20 times, while maintaining acceptable clinical assay performance. The methods use a dual antibody conjugate solution comprising an anti-hapten antibody and a capture antibody against the analyte in each cycle. After the completion of each cycle of reaction, the test probe is dipped in an acidic solution having pH about 1-4, to elute the immunocomplex formed on the probe and to regenerate the hapten-immobilized probe. The robustness of the hapten-coated solid phase allows utilization of multiple denaturation reagents for efficient elution of the immune complexes after each cycle without compromising the binding activity of the hapten on the solid phase.

Abstract: A Central Unit (CU) is connected to multiple Remote Radio Heads (RRHs) over a backhaul. The spatial separation of units creates long round-trip times, which are addressed in the present disclosure. The enhanced operation allows for counting down a BackOff (BO) on either the RRH side or on the CU side. RRHs that perform the BO procedure can resolve the issue of insufficient InterFrame Space (IFS) time for the RRH to obtain Data from the CU and to invoke a BO. In addition, RRHs that perform the BO procedures are able to reduce channel access contention when multiple RRHs are performing BOs, while utilization efficiency for the medium can also be increased by the improved synchronization of BO and Clear Channel Assessment (CCA) status between the CU and RRHs.

Abstract: An enhanced method of handling block Acks, such as for latency sensitive traffic streams, for which a separate block Ack mechanism is established, which is separate from other traffic in the same TID. With this separate block Ack mechanism the recipient STA can have an independent receive reordering buffer control for latency sensitive traffic, so that the MSDU or A-MSDU of latency sensitive traffic can be passed to the next MAC process in order of increasing sequence number of the MSDUs or A-MSDUs since those MSDUs and A-MSDUs have the same QoS requirement, such as the latency time. This mechanism reduces the chances of latency sensitive traffic being stuck in a receive reordering buffer behind other traffic in the TID and having its traffic expire.

Abstract: Protocol enhancements for IEEE 802.11 handling of Buffer Status Reports (BSRs) to provide real-time information on Quality of Service (QoS) requirements. A non-AP STA can report QoS status about portions of a buffer, which then allows the AP to schedule transmissions for those buffers toward satisfying their QoS requirements. The non-AP STA can also change parameters of the QoS characteristics element of an existing SCS to allow the AP to schedule transmission for the SCS traffic with the new parameters immediately. The non-AP STA can also report on buffers that should soon arrive to allow the AP to trigger the transmission before those buffers arrive. Additional benefits are also provided.

Abstract: A wireless communication apparatus, method or protocol for wireless STAs using CSMA/CA on a wireless local area network (WLAN). A receiver STA receives MSDUs or A-MSDUs which include an expiration time, from a transmitter STA. The receiver STA stores the MSDUs or A-MSDUs with expiration time in its receive reordering buffer of the corresponding high-throughput (HT)-immediate block acknowledgement (Ack) agreement. The receiver STA passes the MSDU or A-MSDU to a next MAC process before an expiration time of the MSDU or A-MSDU. Thus, the percentage of latency sensitive traffic packets being communicated prior to expiration is increased.

Abstract: New reverse direction (RD) protocols for EHT devices during reserved target wait time (R-TWT) service periods (SPs). In this protocol the R-TWT scheduling AP does not have to trigger the RD initiator when it performs as the RD responder, and can trigger TB PPDU(s). In addition, the RD initiator is enabled to inform the RD initiator to inform its non-AP peer STA about the R-TWT information in the transmitted RD PPDU. The RD initiator is enabled to send a new MU RD PPDU to both the R-TWT scheduling AP and the non-AP peer STA, which allows the AP to quickly takeover scheduling if the non-AP peer STA is a non-RTWT member and has limited access the in current ongoing R-TWT SP.
