  • Patent number: 10667297
    Abstract: Techniques for mobility-aware contention procedures on a shared communication medium are disclosed. A connection failure associated with mobility between a source access point and a target access point sharing a communication medium may be detected. Based on the detected connection failure, a backoff threshold associated with contention-based access to the communication medium may be adapted. Contention for access to the communication medium may then proceed in accordance with the adapted backoff threshold.

  • Publication number: 20200127781
    Abstract: Systems and methods for wireless communication include a user equipment (UE) and a base station, wherein the UE transmits additional channel state information (A-CSI), along with ACK/NACK (or “A/N”) reporting to the base station in a soft A/N payload. The A/N reporting is responsive to downlink control information (DCI) grants in a downlink transmission from the base station. The A-CSI reporting is responsive one or more DCIs which include a CSI trigger. Even if one or more DCIs with CSI triggers are missed in the downlink transmission, the UE is designed to detect whether there may be any missing DCIs with CSI triggers and provide A-CSI reporting in the soft A/N payload based on this detection.

  • Publication number: 20200112357
    Abstract: Methods, systems, and devices channel quality indicator (CQI) reporting based on demodulation reference signal (DMRS) from a base station are described. In some cases, a base station may configure a user equipment (UE) with such DMRS based CQI reporting (e.g., by transmitting a CQI reporting configuration to the UE). The CQI reporting configuration may specify the UE is to report CQI based on DMRS and, in some cases, may configure the UE to report the CQI with hybrid automatic repeat request (HARQ) feedback. A UE may receive a control message that indicates a resource for reception of a downlink transmission and an uplink control resource for transmission of CQI information. The UE may identify a DMRS of the downlink transmission, calculate a CQI based on the DMRS, and transmit the calculated CQI to the base station via the uplink control resource indicated by the received control message.

  • Publication number: 20200092860
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling, such as a downlink control information (DCI), that identifies a transmission configuration state from a set of transmission configuration states, from which the UE may determine a receiver timing. The UE may then receive a downlink transmission, such as a physical downlink shared channel (PDSCH), from one or more transmission/reception points (TRPs). The UE may use the receiver timing to decode the downlink transmission by performing a fast fourier transform (FFT) with the receiver timing for the downlink transmission.

    Abstract: Certain aspects of the present disclosure provide techniques for user equipment (UE)-centric clustering and efficient scheduling for coordinated multipoint (CoMP). A method for UE-centric clustering and central scheduling includes determining a UE conflict graph. Vertices in the UE conflict graph are UEs for which there is a transmission and edges between vertices are UEs that have a scheduling conflict. The method includes transmitting signaling to schedule the UEs with resources for the transmission based on the UE conflict graph. A method for UE-centric clustering and cluster scheduling includes determining a cluster graph. Vertices in the cluster graph are CoMP clusters for one or more UEs for which there is a transmission and edges between vertices are CoMP clusters that have a scheduling conflict. The method includes transmitting signaling to assign resources to the CoMP clusters based on the cluster graph.

  • Publication number: 20190335480
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive a group physical control channel signaling, which may configure grant uplink transmissions for a set of UEs including the receiving UE. The group physical control channel signaling may indicate allotted resources for configured grant uplink transmissions. The group physical control channel signaling may further indicate a group physical control channel which a UE may monitor for control messages. The UE may transmit a configured grant uplink transmission in accordance with the group physical control channel signaling. The base station may receive the configured grant uplink transmission and may determine a control message which it may transmit in the group physical control channel based on the configured grant uplink transmission. The UE may receive the control message, and may determine whether to retransmit a configured grant uplink transmission based thereon.

  • Patent number: 10448292
    Abstract: A parameter for transmission by an access point is determined in a manner that facilitates access terminal mobility. For example, a cell reselection parameter and/or a handover parameter may be determined based on the quality of a signal from one access point (e.g., a macro cell) at another access point (e.g., a femto cell). In addition, a cell reselection parameter and/or a handover parameter may be determined based on the proximity of one access point (e.g., a femto cell) to another access point (e.g., a macro cell). Through the use of these techniques, a parameter may be determined in a manner that mitigates access terminal ping-ponging between access points and that mitigates outages that may otherwise occur as a result of an access terminal remaining on an access point too long.
