  • Publication number: 20220361193
    Abstract: Embodiments of the present invention provide systems and methods for performing priority service access between EHT non-AP STAs or MLDs using EDCA or UORA parameter sets corresponding to enabled links that can be used to derive priority access (e.g., contention window) information of enabled links for NSEP or LL wireless communication. The EHT non-AP STAs or MLDs can enable, configure, and update priority access for NSEP or LL services using protected action frames or beacon frames, for example. Deriving priority information from the EDCA or UORA parameters carried in protected action frames or beacon frames advantageously avoids increasing the overhead of beacon frames and prevents degradation of spectrum efficiency while supporting NSEP or LL priority services.

  • Publication number: 20220353041
    Abstract: A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH). In a case that a number of bits for downlink control information (DCI) used for indicating the DMRS sequence initialization is 1 bit, a sequence of the DMRS for the PDSCH is generated based on a value indicated by the DCI used for indicating the DMRS sequence initialization. The value is among a value of a first scrambling identity (ID) and a value of a second scrambling ID. In a case that the number of bits for the DCI used for indicating the DMRS sequence initialization is 0 bit, the sequence of the DMRS for the PDSCH is generated based on a value of a third scrambling ID.

  • Publication number: 20220346171
    Abstract: Embodiments of the present invention provide improved multi-link operation over EML links. A non-AP MLD indicating support of EMLMR operation announces it's the number of spatial streams supported for receiving or transmitting after receiving the initial frame exchange during enhanced multi-link multi-radio (EMLMR) operation (MLD level capabilities). MLD level capabilities for operating over the EMLSR links is defined so that the EMLMR capable devices can improve/optimize their performance based on their computing capabilities and RF design.

  • Publication number: 20220338253
    Abstract: Embodiments of the present invention provide improved multi-link operation over for recovering from a transmission failure on a primary link. During synchronous transmission on the NSTR pair of links, a transmission failure of an MPDU may happen on either link of the NSTR pair of links. Error recovery can be performed when an AP MLD is operating on the NSTR pair of links. When a transmission failure is detected, error recovery can be performed, and the timing of a synchronous transmission on the other wireless link can be managed to advantageously avoid IDC interference and improve performance of the wireless network.

  • Publication number: 20220322387
    Abstract: A user equipment (UE) is described. The UE includes reception circuitry configured to receive a first physical downlink control channel (PDCCH) and a second PDCCH. The UE also includes transmission circuitry configured to transmit a physical uplink shared channel (PUSCH). Downlink control information (DCI) carried by the first PDCCH schedules the PUSCH. In a case that the second PDCCH is a group-common PDCCH, the transmission circuitry stops transmission of the PUSCH on resources indicated by the second PDCCH. In a case that the second PDCCH includes a rescheduling DCI, the transmission circuitry transmits the PUSCH on the resources indicated by the rescheduling DCI.
