  • Patent number: 10812982
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) operating in unlicensed spectrum may determine that a base station is not transmitting during a particular time period (e.g., by detecting the absence of a control signal). The UE may then perform a listen-before-talk (LBT) procedure and, if the channel is available, may perform an autonomous uplink (UL) transmission. The autonomous UL transmission may include control information to facilitate decoding. Thus, the base station may receive the control information, and decode the rest of the autonomous UL transmission accordingly. The base station may configure the UE for autonomous UL transmissions when the radio link is established, and may also send dynamic configuration information to initiate, suspend, or reconfigure parameters for autonomous UL transmissions.

  • Patent number: 10812214
    Abstract: Techniques are described for wireless communication. A first method includes sensing an indication of first radio access technology (RAT) communications occupying a shared radio frequency spectrum band; and configuring, in response to the sensing, at least one parameter of a second RAT used by a device to contend for access to the band. A second method includes randomly selecting a number from a range of numbers extending between a lower bound and an upper bound; contending for access to a shared radio frequency spectrum band by performing an extended clear channel assessment (ECCA) procedure over a plurality of CCA slots, the plurality of CCA slots including a first number of CCA slots equal to the upper bound; and winning contention for access to the band after determining, while performing the ECCA procedure, that the band is available for a second number of CCA slots equal to the randomly selected number.

  • Patent number: 10805816
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. An eNB determines a CCA parameter for use by a UE in performing a CCA procedure for UL transmission and transmits an indication of the CCA parameter to the UE. The UE receives an indication of the CCA parameter for UL transmission from the eNB and performs the CCA procedure for UL transmission using the indicated CCA parameter. The UE may transmit to the eNB prior to receiving the indication of the CCA parameter. The eNB may use the report in determining the CCA parameter for use by the UE.

  • Patent number: 10790949
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may establish a concurrent connection with different cells from two base stations. During a certain time period, the UE may be power limited for transmissions to the first base station but not for the second base station. In some cases, the UE may then transmit an SRS to the second base station and drop or reduce the power of an SRS transmission to the first base station. In other cases, the UE may determine that a first cell or a second cell is in a power limited state due to scheduled transmissions for the respective cells. In such cases, the UE may drop a scheduled transmission or scale transmission power of the first and second cells by a common value.

  • Publication number: 20200281027
    Abstract: Technology neutral coexistence and high priority traffic is disclosed for use in unlicensed frequency bands. Synchronization boundaries are defined in which synchronous contention windows across all radio access technologies attempting access to a shared communication channel occur periodically. Between the synchronous contention windows, the nodes may return to asynchronous access procedures. Such synchronous access procedures may be applicable to certain power classes or deployment type nodes. Additionally, various priority schemes for the synchronous contention window may be used to ensure protection of higher priority nodes or traffic, such as ultra-reliable low latency communication (URLLC) traffic. According to certain aspects, the deployment of such synchronous access methodology may be triggered via signaling from initiating devices.

  • Patent number: 10764775
    Abstract: Various techniques are proposed to enhance or expand the capabilities or usage of buffer status request (BSR) and scheduling request (SR) in new radio (NR) applications. In an implementation, techniques are proposed to extend the SR in long term evolution (LTE) baseline with additional information to help a base station (e.g., gNB) schedule faster and more efficiently. Moreover, a new BSR triggering condition is proposed to report new data based on particular events instead of being time-based. Modifications being proposed to both BSR and SR can be customized for different numerologies/transmission time intervals (TTIs). Modifications being proposed to SR can also be used to indicate a user equipment (UE) new beam selection after recovering from a beam failure.

  • Publication number: 20200275408
    Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication. A user equipment (UE) may acquire a triggering synchronization signal block (SSB), which enables the UE to monitor for a floating Type-2 physical downlink control channel (PDCCH) and to determine a subset of paging occasions (POs) to monitor. Or, the UE may monitor for a fixed Type-2 PDCCH, where the UE does not require a triggering signal to monitors POs. In another aspect, the UE may monitor for a paging transmission during a monitoring period. The UE may determine the monitoring period based on received signaling. The UE may receive the signaling, during the monitoring period, indicating that the monitoring period is to be ended before a scheduled end of the monitoring period. In this way, the UE may support a continuity requirement associated with downlink reference signaling (DRS) and may support reception of paging in a shared channel.
