  • Publication number: 20190281475
    Abstract: Methods and apparatus related to interference management for a spectrum (e.g., unlicensed band) shared among multiple wireless communication devices (e.g., user equipment or base stations). A first wireless communication device may generate and transmit to a second wireless communication device an indication that facilitates interference management (e.g., interference estimation, suppression, and/or mitigation). For example, an interfering device may indicate its transmission characteristics to an interfered device to facilitate receiver-side interference suppression, or an interfered device may indicate its reception characteristics to an interfering device to facilitate transmitter-side interference mitigation.

  • Publication number: 20190280836
    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: 10411928
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may communicate using a dynamic cyclic prefix (CP) length to reduce communications overhead. That is, the wireless device may use a CP length that is changeable for each data packet or listen-before-talk (LBT) frame. For example, the wireless device may initially communicate using a first CP length and then receive a dynamic CP indication for subsequent symbols in one or more data packets or LBT frames. The wireless device may then communicate using the different CP length based on the indication. In some examples, the indicated dynamic CP length may be based on a cell radius of a base station, a data direction, or the location of a user equipment (UE) in relation to the base station.

  • Patent number: 10412704
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a configuration for enhanced paging to a UE being served by a cell over a shared frequency band. The enhanced paging may include multiple paging intervals for each paging cycle. The UE may enable reception for a paging interval and determine whether the UE receives a downlink transmission. The UE may lengthen a paging interval or enable reception during a second paging interval based in part on determining whether the UE receives a downlink transmission. In some examples, the UE may receive a paging queue status indication indicating that paging information will be transmitted during a paging interval or a later interval, or indicating that no paging information is present at a serving cell.

  • Patent number: 10404509
    Abstract: Methods, systems, and devices for wireless communication are described for slot structures using guard intervals in a single carrier waveform. Techniques provide for generating a first waveform for control information or reference signal transmissions in a first subset of symbols, and generating a second waveform for data to be transmitted in a second subset of symbols. A combination waveform may be generated based on the first and second waveforms that is transmitted to a receiver, such as by concatenating the first and second waveforms. The first waveform may be generated by appending a guard interval (GI) sequence to a reference signal or control information, and performing a discrete Fourier transform spread frequency division multiplexing (DFT-s-FDM) procedure. The second waveform may be generated by appending the GI to data to be transmitted in each symbol of the second subset of symbols, and performing the DFT-s-FDM procedure.

  • Patent number: 10405335
    Abstract: Soft channel reservation in shared spectrum networks is discussed. In network areas where multiple wireless nodes, whether from the same or different network operators, share spectrum using a channel reservation signaling form of contention resolution, an aggressor transmitter listens for a neighbor receiver's receiver channel reservation signal to the neighbor transmitter the neighbor receiver is in communication with. The receiver channel reservation signal includes channel condition information that the aggressor transmitter can use to estimate an interference impact at the neighbor receiver should the aggressor transmitter performs its transmissions to its own receivers. Based on whether this estimated interference impact exceeds or remains within a particular threshold, the aggressor transmitter may decide whether or not to back off of its transmissions until a later time.

  • Publication number: 20190268902
    Abstract: Methods, systems, and devices for wireless communications are described that support slot format determination for extended cyclic prefix (ECP) transmissions using normal cyclic prefix (NCP) slot formats. A slot format indicator (SFI) for NCP slots may identify transmission directions (e.g., uplink symbols, downlink symbols, or flexible symbols) for different symbols within a slot, and the SFI may provide an indication of a particular slot format that is to be used. Starting and ending times of each NCP symbol in a slot may be time domain mapped to starting and ending times of each ECP symbol in the slot. A transmission direction of each ECP symbol may be determined based at least in part on the transmission direction of at least a portion of at least one NCP symbol that fully or partially overlaps in the time domain with a corresponding ECP symbol.

  • Publication number: 20190268933
    Abstract: Over-the-air (OTA) dynamic time division duplex (TDD) is disclosed with a channel use indicator (CUI) receiver (CUI-R) signal multiplexed in uplink transmissions. According to various aspects, a user equipment (UE) may receive a downlink grant from a serving base station, in which the downlink grant identifies downlink transmissions in one or more subsequent communication slots. The UE may identify a trigger for transmission of a channel usage signal associated with the grant that may be received by neighboring UEs that may potentially interfere. The UE transmits the channel usage signal in a next scheduled uplink region and then receives downlink data from the serving base station according to the downlink grant. If the neighboring UE receives a conditional uplink grant, then it may proceed with uplink transmissions when it fails to detect the channel usage signal from the UE.

  • Publication number: 20190268778
    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.
