  • Publication number: 20190319833
    Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a UE. The apparatus switches from a first, active BWP to a second, active BWP. Then, the apparatus measures a first radio link quality of a configured CORESET TCI or a beam failure detection RS upon switching to the second, active BWP. For example, the apparatus may switch the active BWP based on detecting an expiration of a BWP inactivity timer. The apparatus may then determine based on a threshold radio link quality whether to perform a measurement of a second radio link quality of a beam failure recovery candidate resource set or to continue to monitor the configured CORESET TCI in the second, active BWP.

  • Patent number: 10440731
    Abstract: A connection may be established between a base station and a user equipment (UE) using a radio frequency shared by multiple network operating entities. Resources (e.g., a frame) may be divided into exclusive, prioritized, and opportunistic sub-intervals for a given network operating entity coexisting within the shared radio frequency spectrum. Additionally, a set of low latency sub-intervals (e.g., reserved resources) may be designated for use by the network operating entity for mission critical (MiCr) and/or autonomous uplink transmissions. The network operating entity may indicate timing information for low latency sub-intervals during a sub-interval for exclusive use by the network operating entity. The UE may then transmit MiCr and/or autonomous uplink messages using the low latency intervals without performing a medium sensing procedure. In some cases, the sub-intervals for MiCr and autonomous uplink transmissions may be for exclusive use by the network operating entity.

  • Publication number: 20190305834
    Abstract: Reference signal and transmitter (Tx)/receiver (Rx) precoding for user equipment (UE) multiplexing in new radio (NR) shared spectrum networks is discussed. In certain reference signals, a base station may schedule multiple UEs for transmission of uplink reference signals within an identified subframe. The base station may transmit a reference signal configuration message, wherein the reference signal configuration message includes a transmission sequence identifier identifying a multiplexing for antenna ports assigned for transmission of the uplink reference signals. The multiplexing may be one or both of frequency divisional multiplexing (FDM) and time division multiplexing (TDM) over the identified subframe. Additional reference signals, transmit precoders may be identified by the base station based on channel inversion calculations of the channel matrix determined based on uplink reference signals.

  • Patent number: 10432386
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a configuration for uplink and downlink communications that defines subframe configuration options for each subframe of a frame. For example, the configuration may establish parameters for time division duplexing (TDD) operation between a base station and a user equipment (UE). The wireless device may determine a constraint for a subframe of the frame based on the configuration and determine an adaptive subframe configuration based on the constraint. The adaptive subframe configuration may include one or several downlink symbol periods and one or several uplink symbol periods. The wireless device may communicate during the subframe according to the adaptive subframe configuration rather than the original configuration. The adaptive subframe may be constrained by the identified uplink and downlink configuration, which may avoid disruption to UEs.

  • Publication number: 20190296881
    Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications network may set priorities for cell groups in dual connectivity. A higher priority cell group may reserve slots and indicate the reserved slots to the lower priority cell group, for example by a backhaul connection. The high priority cell group may also indicate additional, non-reserved slots, which the lower priority cell group may reserve or use for scheduling. One of the cell groups may transmit a slot format indication (SFI) to a user equipment (UE) in the dual connectivity to indicate the slot reservations. In some cases, a hybrid automatic repeat request (HARQ) timing parameter may be based on a number of reserved slots. In some cases, power control may be varied based on whether the UE is capable of simultaneous uplink and downlink transmission.

  • Patent number: 10420082
    Abstract: Techniques for sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same subframe. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.

  • Patent number: 10420078
    Abstract: Systems and methodologies are described that facilitate defining new control channels in legacy wireless networks. Control data resources for new systems can be defined over resources reserved for general data communications in the legacy wireless network specification. In this regard, legacy devices can still be supported by devices implementing new control data resources, and the new control data resources can avoid substantial interference that is typically exhibited over legacy control and/or reference signal resources by instead using the general data resources. In addition, new system devices can avoid scheduling data communication resources over the new control resources to create a substantially non-interfered global control segment. Control data can be transmitted over the segment using beacon-based technologies, reuse schemes, and/or the like.

  • Patent number: 10420052
    Abstract: Estimation of frequency error is disclosed through use of beacon or preamble transmissions. A base station transmits one or more preamble tones at predetermined frequencies using all allocated transmission power associated with the transmission bandwidth for the one or more preamble tones. The base station then transmits its synchronization signals. A UE collects a set of samples from the received transmissions waveform and successively transforms the samples to a frequency domain. The UE may then detect the preamble tones as having at least a threshold power relative to other samples in the transformed samples. The frequency error may then be set as the difference between the detected frequency or frequencies of the received preamble tones and the known predetermined transmission frequency.
