  • Patent number: 10820252
    Abstract: Methods, systems, and devices for radio resource management (RRM) measurement and reporting for license assisted access (LAA) cells operating in unlicensed or shared frequency spectrum are described. A user equipment (UE) may receive an RRM measurement configuration including a channel occupancy parameter for measuring neighbor cells of a shared frequency band. The channel occupancy parameter may be used to determine a channel occupancy metric that may be sent to a base station for cell selection. The channel occupancy metric may include an averaged or filtered received signal strength and may be reported for serving cells and/or intra-frequency neighbor cells. A base station may further configure a UE with a discovery reference signals (DRS) measurement timing configuration (DMTC), which may include an extended DMTC search window. The UE may search for DRS transmissions from neighbor cells according to the DMTC.

  • Publication number: 20200322954
    Abstract: Various designs for optimization of carrier aggregation (CA) capability signaling are discussed. A user equipment (UE) configured for CA determines to signal supported CA combinations that include a band, the band being one of a first band and a second band. The first band is a superset of the second band. The UE signals the supported CA combinations that include the band to the network. A base station receives a signal indicating the CA combinations supported by the UE that include the band. The base station determines CA combinations that include the first band and CA combinations that include the second band based on the CA combinations received from the UE.

  • Patent number: 10779256
    Abstract: Techniques described herein are directed toward enabling location support for 5G New Radio (NR) wireless access by a user equipment (UE) by utilizing existing LTE location support. More specifically, LTE positioning protocol (LPP) messages may be communicated between a UE with NR wireless access and a location server (e.g. an LMF) in a 5G Core Network via an NG-RAN. The LPP messages may support RAT-independent and E-UTRA position methods by the UE such as A-GNSS or OTDOA for E-UTRA. The location server may obtain OTDOA related information from eNBs and ng-eNBs supporting LTE wireless access. A UE may request measurement gaps from a 5G base station (e.g. gNB) in order to obtain measurements for RAT-independent and E-UTRA position methods and may request an idle period in order to obtain LTE timing needed for E-UTRA measurements.

  • Patent number: 10778401
    Abstract: Certain aspects of the present disclosure provide techniques for multiple radio access technology (RAT) carrier aggregation (CA), such as Long Term Evolution (LTE)-New Radio (NR) CA. The method, in one example, comprises generating a first resource coordination information (RCI) comprising one or more resource coordination bitmaps indicating one or more shortened transmission time intervals (sTTIs) of a TTI assigned to the first RAT for communication, wherein the TTI comprises a plurality of sTTIs. The method further comprises transmitting a message including the first RCI to a second base station that uses a second RAT. The method further comprises receiving an acknowledgement of the message from the second base station, the acknowledgment including a second RCI comprising one or more modified resource coordination bitmaps indicating the one or more sTTIs assigned to the first RAT for communication and one or more additional sTTIs of the TTI assigned to the second RAT.

  • Publication number: 20200275299
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a measurement configuration on a first cell specifying a measurement gap for measuring cells on other frequencies. The UE may then measure a second cell and determine an offset between the timing of the two cells. If the measured frequency band is synchronized (or nearly synchronized), the length of the measurement gap may be reduced. In some cases, the UE may then make measurements on the second cell using a reduced measurement interval, and the UE may power down certain components during the rest of the measurement gap to conserve power. In other cases, the UE may coordinate with the serving cell to reduce the measurement gap to minimize the interruption caused by the gaps.

  • Patent number: 10757567
    Abstract: Aspects of the disclosure relate to dual connectivity reporting. In one example, a dual connectivity communication is established, which includes a communication with a master node according to a first radio access technology (RAT), and a communication with a secondary node according to a second RAT. A change in measurement capability is then detected, and subsequently reported to the master node and/or secondary node. In another example, a scheduling entity establishes a first or second communication of a dual connectivity communication with a scheduled entity. The first communication is established according to a first RAT when operating as a master node, and the second communication is established according to a second RAT when operating as a secondary node. An indication is then received from the scheduled entity of a change in measurement capability, and the first and/or second communications are reconfigured in response to the change in measurement capability.

  • Patent number: 10708920
    Abstract: Methods and apparatuses of wireless communications are provided to dynamically determine capability information such that potential configuration and/or resource conflicts may be mitigated among multiple connections while one or more of on-going connections are not interrupted. A user equipment (UE) establishes one or more connections with a network. The UE allocates, in a first resource allocation, one or more resources of the UE to the one or more connections. The UE dynamically determines an instantaneous UE capability information (IUCI) of the UE in response to a change from the first resource allocation to a second resource allocation, the IUCI indicative of the capability of the UE during a predetermined time period. The UE transmits the IUCI to the network to mitigate potential resource allocation conflict among the one or more connections while maintaining at least one of the connections.

  • Publication number: 20200187137
    Abstract: Certain aspects of the present disclosure relate to reporting difference in timing between cells using multiple connectivity in a wireless network. A first connection served by at least a first cell and a second connection served by at least a second cell to facilitate communicating with at least the first cell and at least the second cell are established. A reporting configuration specifying one or more parameters related to reporting a timing difference between cells is received. A timing difference between at least the first cell and at least the second cell is determined, and the timing difference is reported to at least the first cell over the first connection or to at least the second cell over the second connection. This can facilitate scheduling time aligned operations over the first and second cells, or related cell groups, in multiple connectivity.
