  • Patent number: 10667282
    Abstract: Aspects of the present disclosure provide a mechanism for utilizing uplink hopping patterns for HARQ transmissions. Each hopping pattern may include a sequence of different frequency resources or a sequence of different scrambling sequences for a user equipment (UE) to utilize over time for HARQ transmissions. Each of the hopping patterns may further be associated with a time index mode in which the hopping pattern is applied to time resources such that each time resource within a consecutive sequence of time resources is mapped to a different frequency resource or scrambling sequence. The base station may select a hopping pattern for a particular UE and transmit an indication of the selected hopping pattern to the UE.

  • Patent number: 10666984
    Abstract: Methods and apparatus for coding video information having a plurality of video samples include partitioning samples into groups for transmission within a single clock cycle, wherein the samples are associated with a bit length B, and a group having a group size K. The sample group is mapped to a code number and coded to form a vector-based code comprising a first portion identifying a type of look-up-table used to performing the mapping, and a second portion representing the samples of the group. The look-up-table may be constructed based upon occurrence probabilities of different sample groups. In addition, different types of look-up-tables may be used for different B and K values.

  • Patent number: 10667090
    Abstract: Techniques are discussed herein for enabling an external client to request periodic or triggered location of a user equipment (UE) according to trigger criteria that are not visible to entities within a wireless network, using a codeword in a periodic and triggered location request that is sent to the UE. The codeword may be meaningful to the UE, but not to the wireless network, and may indicate particular types of triggered and/or periodic events to be detected and reported by the UE. A location report sent by the UE to the wireless network may contain a second codeword, indicating a type of triggered or periodic event detected by the UE, which may be conveyed by the wireless network to the external client without interpretation. Codewords may enable more flexibility for periodic and triggered location without impacting wireless networks.

  • Patent number: 10667222
    Abstract: Aspects of the present disclosure provide techniques for the user equipment (UE) to select a power management mode from a plurality of power management modes supported by the UE based on decoding of a portion of the downlink subframe. For example, when the UE receives a subframe from a base station, the UE may decode a control channel region of the subframe to determine whether the subframe includes a channel grant allocated to the UE. If no channel grant is included in the subframe, the UE may select a power management mode for the UE from the plurality of power management modes supported by the UE that maximizes the UE's sleep opportunities while balancing the deficient performance costs.

  • Patent number: 10667267
    Abstract: Methods, systems, and devices for wireless communication are described to provide priority traffic grant-less access to pre-defined communication resources that are semi-persistently scheduled. A set of semi-persistent communication resources may be reserved for use by priority traffic. If the semi-persistent resources are not used for priority traffic, the semi-persistent resources may be scheduled for use by other types of traffic. As priority traffic is identified, the priority traffic may be transmitted using the semi-persistent resource without having those communication resources granted by a scheduling entity. Such grant-less access to the semi-persistent resources may result in collisions between the scheduled traffic and the priority traffic.

  • Patent number: 10667259
    Abstract: Methods, systems, and devices for wireless communication are described for a channel reservation signal that may be transmitted upon gaining contention-based access to a channel in a shared radio frequency spectrum. The channel reservation signal may include a channel reservation preamble and a channel reservation payload. The channel reservation payload may be formatted with other control channel information transmitted by the transmitter, such as downlink control information (DCI), and aligned with a transmission boundary of the other control channel information. When deployed on a shared medium, a downlink control channel may carry an extra trigger field that may schedule a receiving UE to transmit its own channel reservation signal within an uplink transmission burst.

  • Patent number: 10667173
    Abstract: Methods, systems, and devices for wireless communication are described that provide for generation of feedback at a code block (CB) level for a received transmission in which a transmit block (TB) includes a number of CBs. The feedback may indicate a request for a retransmission of one or more CBs, and retransmissions of the CBs may be provided at a repetition level that provides multiple repetitions of the one or more CBs. The repetition level may provide for two or more retransmissions of the one or more CBs. In some cases, the repetition level is configurable, and may be based on a number of requests for retransmission that are received. The configuration of repetition levels may be through radio resource control (RRC) signaling, downlink/uplink control information, or any combination thereof.
