  • Patent number: 12086192
    Abstract: An exception handling machine is configured to receive a first document from a source document processing system and provide a first revised document to a destination document processing system. The exception handling machine is configured to detect an exception flag in at least one data field of the first document and determine at least one exception handling rule for the first document based on at least one other data field in the first document and the exception flag, determine an exception code corresponding to the exception handling rule, insert the exception code into the first document to generate the first revised document, and provide the first revised document to the destination document processing system. The destination document processing system is programmed to respond to the exception code inserted in the revised first document by providing the first revised document to a client device connected to the destination document processing system.

  • Publication number: 20240298349
    Abstract: Present TID-to-link (T2L) mapping is limited in to only mapping the UL and/or DL direction. Mechanisms are taught for providing T2L mapping for TDLS link, while R-TWT features can be extended to setup R-TWT membership on a TDLS link. Using the T2L mapping for a TDLS link, different traffic with different priorities can be differentiated and directed on different TDLS direct links to reduce interference on any single link and to allocate the RTA traffic to channels which have wider bandwidths and less traffic congestion.

  • Publication number: 20240298312
    Abstract: Wireless protocol enhancements are provided for allowing inter-BSS stations/APs to support, negotiate and participate in cooperative R-TWT SPs that are overlapped in time and are scheduled on different links or different channels to avoid the inter-BSS interference of prioritized traffic that has been scheduled to transmitted during the corresponding R-TWT SPs. The protocol makes use of new subfield elements toward informing, negotiating and supporting the cooperative R-TWT SPs.

  • Patent number: 12075471
    Abstract: A wireless local area network (WLAN) protocol allowing a Transmit Opportunity (TXOP) holder, whether its an AP or non-AP STA, to share the TXOP with other stations, that are either AP or non-AP STAs. An intent to share the TXOP is communicated by the TXOP holder either directly or indirectly with other STAs and/or AP, after which scheduling information (time and duration) are shared with the STAs and/or AP. When the TXOP occurs, the STAs and/or AP can access the channel at the time and for the duration specified, thus providing increased use of the TXOP to improve efficiency.

  • Publication number: 20240224323
    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.

  • Patent number: 11963224
    Abstract: A wireless local area network (WLAN) protocol having a non-zero backoff procedure which is bounded by setting a backoff counter to a random value greater than or equal to at least one backoff slot in starting to contend for a channel. This is preferably utilized in combination with setting the Arbitration Inter-Frame Spacing (AIFS) time to an amount less than that utilized for a legacy backoff. The parameters controlling the non-zero backoff may be set by the station performing the contention, or by an associated Access Point (AP), or in response to negotiation between the station and the AP. In some cases the station can switch between enabling and disabling the non-zero backoff procedure during different periods of time.

  • Publication number: 20240080891
    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.

  • Publication number: 20240007852
    Abstract: Using this described protocol an AP can control multiple STAs to allow them to utilize the same scrambling seed to scramble the data in identical data units being sent on the wireless network. The AP sends a scrambling seed indication within a frame communicated to other STAs on the network. These other STAs, then use this scrambling seed indication to scramble a data field of a data unit with an identical scrambling seed, and to transmit these packets using the same modulation and coding scheme (MCS).

  • Publication number: 20240008081
    Abstract: A wireless protocol allowing an AP to allocate time within a transmit opportunity (TXOP) to non-AP stations. The allocations are made under condition that the non-AP STA(s) will satisfy Access Class (AC) requirements communicated in a frame sent by the AP STA, such as within an MU RTS TXS Trigger frame. Upon receiving the frame, the non-AP responds on whether it can meet the conditions, such as within a Clear-To-Send (CTS) message. If the non-AP can meet the conditions, then it proceeds to transmit data (to the AP, or a peer non-AP). Otherwise, if it cannot meet the conditions, then the AP can communicate the allocation to another non-AP STA. There are also conditions for how the non-AP can aggregate data units into A-MSDUs.

  • Patent number: 11856606
    Abstract: A wireless local area network (WLAN) protocol allowing a Transmit Opportunity (TXOP) holder to share the TXOP with other stations (STAs) residing in either the same Basic Service Set (BSS) of the TXOP holder, or in an other BSS (OBSS). An intent to share the TXOP is communicated to the Access Point (AP), and/or directly to other STAs. Scheduling information (time and duration) are shared with the STAs either directly, or through one or more APs. When the TXOP occurs, the STAs can access the channel at the time and for the duration specified, thus providing increased use of the TXOP to improve efficiency.

  • Patent number: 11838957
    Abstract: Enhanced Multi-Link Operation (MLO) is performed in this protocol in which non-simultaneous transmit/receive (NSTR) Multi-Link Devices (MLDs) cooperate with each other in sharing a portion of their available Transmit Opportunity (TXOP) toward reducing contention and competition for channel access across the group of cooperating MLDs. The shared TXOP is performed at an MLD level after all links for an NSTR MLD are obtained by stations which do not need to be in part of the same NSTR MLD, thus synchronized transmissions and receptions are performed which eliminate in-device coexistence (IDC) interference in any single NSTR MLD. The time gap while awaiting for all links to be obtained, is also made use of for performing transmission(s) toward increasing data throughput.

  • Publication number: 20230319620
    Abstract: Enhanced TID-to-UP mapping is performed which allows multiple TIDs to be mapped to the UPs of the same AC. Thus, a first STA can set TID-to-UP mapping for a second STA, whereby TID-to-UP mapping can differentiate the MSDUs or A-MSDUs that are transmitted. In addition, an MSDU / A-MSDU can be classified by TID first, then use TID-to-UP mapping to map it to the corresponding UP. In addition, an SCS traffic stream can assign a TID and a UP to that SCS traffic stream. The use of these enhanced mechanism can enhance low latency performance.
