  • Patent number: 11239891
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a report indicating that a cooperative reception group including the UE and one or more other UEs connected to the UE over an out-of-band link supports one or more downlink transmit beamforming techniques. The UE may determine, based at least in part on the one or more downlink transmit beamforming techniques supported by the cooperative reception group, a downlink transmit precoder associated with relaxed beamforming nulling. The UE may decode a downlink transmission received from the base station based at least in part on the downlink transmit precoder and one or more decoded bits received from the one or more other UEs in the cooperative reception group. Numerous other aspects are provided.

  • Patent number: 11212760
    Abstract: Narrowband communications in a wireless communications system may include a common synchronization signal, such as a primary synchronization signal (PSS), secondary synchronization signal (SSS), or physical broadcast channel (PBCH). Content of the common synchronization signal may indicate a location of narrowband data transmissions in a narrowband region of a system bandwidth. The location of the narrowband region may be in-band within one or more wideband transmissions, within a guard-band bandwidth adjacent to the wideband transmissions bandwidth, or within a stand-alone bandwidth that is non-adjacent to the wideband transmissions. The common synchronization signal may be located within a predefined search frequency and may include an anchor synchronization channel present in certain resources of allocated narrowband communications resources.

  • Patent number: 11212051
    Abstract: Beam-specific autonomous uplink (AUL) resources may be configured with an associated reference signal for beam management. For example, a base station may configure respective sets of AUL resources that are specific to one or more base station receive beams. These sets of beam-specific AUL resources may be configured to be associated (e.g., quasi co-located (QCL)) with a reference signal, such as a channel state information reference signal (CSI-RS), a synchronization signal burst (SSB), or the like. The base station may periodically transmit the reference signals that are associated with the AUL resources. A user equipment (UE), upon detecting one or more of the reference signals, may identify which set of AUL resources are available for an AUL transmission of uplink data. In such cases, the UE may select a set of AUL resources based on a signal strength of the reference signal associated with that set of AUL resources.

  • Patent number: 11202183
    Abstract: Methods, systems, and devices for wireless communication are described. User equipment (UE) and base stations may support frequency hopping with fast retuning for enhanced machine type communication (eMTC). For example, a UE may need to retune portions of its receive or transmit chain to support operation on various frequency bands, and it may perform the retune within a few symbols. Both base station and UE may anticipate or account for the retuning delay and communicate accordingly. A base station may refrain from transmitting for a certain period of time, for example. A base station may also account for frequency hopping delays for uplink communications. Systems may employ other techniques to support eMTC. For example, UEs may leverage reference signal patterns in certain control channels for demodulation. In some cases, base stations may alter control channel transmissions to account for various types of UEs with in the system.

  • Patent number: 11197166
    Abstract: Synchronous communications mode detection is disclosed for unlicensed spectrum communications. To detect synchronous mode communications, an observing node monitors on-off transitions of communication transmissions on a shared communication spectrum. The observing node detects the on-off transition spacing of the on-off transitions over a sliding window of a detection period duration. The node may determine the number of candidate synchronous on-off transition spacings of the detected on-off transition spacings that are equal to an integer multiple of a synchronization period. If the number of candidate synchronous on-off transition spacings exceeds a threshold value the observing node will declare detection of a synchronous operation mode of the shared communication spectrum.

  • Patent number: 11184777
    Abstract: Methods, systems, and devices for wireless communications are described. A base station of a first network operator (OP) may determine a priority for the first OP for a transmission opportunity of a shared or unlicensed channel.

Base station may transmit a tentative grant to a user equipment (UE) of the first OP scheduling transmissions over resources of the transmission opportunity. The transmitting device of the first OP may monitor a contention window for reservation signals communicated by devices of the second OP. Based on the monitoring and the tentative grant, the transmitting device of the first OP may perform the transmission over the resources of the shared or unlicensed channel.

    Abstract: Coordination of listen before talk (LBT) structure in new radio (NR) unlicensed (NR-U) multi-channel access operations is disclosed. In one aspect, when a base station determines to access shared communication spectrum, it may transmit an LBT structure signal that identifies the current LBT structure. The base station would then attempt access to the shared spectrum according to the LBT structure. In another aspect, a coordination server is used to manage access to the shared spectrum. Each node desiring access registers with the coordination server, which provides access parameters for the accessing node to use that increases the likelihood of successful access. The accessing nodes will transmit the selected access configuration used to access the shared spectrum, wherein the access configuration is selected based on the access parameters.

  • Patent number: 11172370
    Abstract: Methods, systems, and devices for wireless communication are described. Discontinuous reception (DRX) operation may be configured differently on enhanced component carriers (eCCs) than on other component carriers, including a primary cell (PCell). In some cases, a user equipment (UE) may be configured with several different eCC DRX modes. An eCC DRX configuration may, for example, be coordinated with downlink (DL) transmission time interval (TTI) scheduling so each DRX ON duration may correspond to a DL burst duration of the corresponding eCC. The eCC DRX ON durations may also be scheduled according to hybrid automatic repeat request (HARQ) process scheduling. In some examples, eCC DRX ON durations may be based on listen-before-talk (LBT) procedures. In some cases, eCC DRX ON durations may be configured to contain an uplink (UL) burst to enable channel state information (CSI) reporting. The eCC DRX may also be configured to minimize interruption of the PCell.

  • Publication number: 20210337540
    Abstract: Methods, systems, and devices for wireless communications are described that provide for frame-based initiator device operations. A wireless device may be operating within a frame-based equipment communications system, where a frame may include a channel occupancy time period and a minimum idle period. An initiating device may be configured to initiate autonomous uplink communications during the channel occupancy time period of its frame, while the device may not initiate communications during an idle period of its frame. In some cases, a frame-based equipment communications system may include more than one initiating device, where the idle periods for different initiating devices may occur at different times. In some cases, the initiating device may be configured to initiate communications during the idle period for another initiating device. This may allow the wireless system to decrease system overhead associated with a minimum idle period per frame.
