  • Patent number: 11374715
    Abstract: The described technology is generally directed towards adapting the demodulation reference signal sent in a wireless resource data block based on channel estimation performance. In general, if the demodulation reference signal received was not successfully able to be used to demodulate the resource data block, the demodulation reference signal density can be increased up to a maximum density, which costs resource elements but improves the channel estimation accuracy. If the demodulation reference signal received was able to be used to demodulate the resource data block, the demodulation reference signal density can be decreased down to minimum density, which saves resource elements for data. The network device can use HARQ ACK/NACK data (e.g., a current count or counted over a time period) to determine channel estimation performance, and/or the user equipment can recommend a demodulation reference signal density change.

  • Patent number: 11375448
    Abstract: A method for beacon information provisioning, transmissions and protocol enhancements includes defining multiple level beacons based on the attributes of beacon information fields/elements. A short beacon may be used in addition to a primary beacon in space-time block code (STBC) modes, non-STBC modes and in multiple bandwidth modes. The short beacons may also be used for Fast Initial Link Setup (FILS) and to extend system coverage range. Beacon transmissions may use adaptive modulation and coding set/scheme (MCS).

  • Patent number: 11374704
    Abstract: Aspects described herein include a method comprising predicting, based on one or more transmission characteristics, error values for a sequence of bit positions used for modulating data within a packet. The method further comprises generating a bitmap that maps one or more payload bits and one or more padding bits of the packet to respective bit positions of the sequence. The one or more padding bits are preferentially mapped to respective bit positions having relatively greater error values. The method further comprises modulating the sequence according to the bitmap.

  • Patent number: 11375426
    Abstract: Methods and apparatus for a mobility mechanism in the scenario including both enhanced packet core (“EPC”) and 5GC are disclosed. One method of a UE comprising receiving system information including a cell list from an eNB/ng-eNB, wherein, the cell list includes an identifier of a cell connected to EPC or an identifier of a cell connected to 5GC. Further, the identifier is a Physical Cell Identifier (“PCI”) of the cell, and the cell indicated in the cell list includes a serving cell for the UE and/or one or more neighbour cells of the serving cell. Further, the eNB/ng-eNB from which the system information is received can be the eNB/mg-eNB managing the serving cell for the UE or the eNB/mg-eNB managing the neighbour cells of the serving cell.

  • Patent number: 11375410
    Abstract: Embodiments of this application disclose a method and apparatus for obtaining configuration information performed at a terminal. The terminal obtains configuration information of a 5G local area network (LAN), the configuration information including an information item for assisting the terminal in making an access decision and at least one of the following information items: a first information item, for indicating whether the 5G LAN supports maintenance of session continuity with a public land mobile network (PLMN); a second information item, for indicating an identifier of the 5G LAN; and a third information item, for indicating a service-level agreement (SLA) of the 5G LAN. Next the terminal determines whether to access the 5G LAN according to the configuration information.

  • Patent number: 11375422
    Abstract: A method by a coordination node is provided for controlling communications between Li-Fi APs and UEs. The method includes receiving peer connectivity reports from Li-Fi APs which identify Li-Fi APs having at least partially overlapping coverage areas, and developing a handover pathway data structure, based on the peer connectivity reports, that identifies Li-Fi APs that can receive communication handover from other identified Li-Fi APs. The method further includes determining an identifier of a first Li-Fi AP providing Li-Fi communication service for a UE, and accessing the handover pathway data structure using the identifier of the first Li-Fi AP to determine an identifier of a second Li-Fi AP to which handover from the first Li-Fi AP can be performed. The method then initiates handover of the Li-Fi communication service for the UE from the first Li-Fi AP to the second Li-Fi AP.

  • Patent number: 11375399
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may transmit a first physical downlink shared channel (PDSCH) communication to a user equipment (UE), wherein the first PDSCH communication includes a first set of layers for a codeword, and wherein a second set of layers for the codeword are transmitted to the UE in a second PDSCH communication from a second TRP. The first TRP may receive from the UE, acknowledgement or negative acknowledgement (ACK/NACK) information corresponding to the codeword. The first TRP may adjust a contention window size based at least in part on a determination that a condition, associated with the ACK/NACK information, is satisfied. Numerous other aspects are provided.
