Abstract: A user equipment (UE), or other network component can operate to configure a plurality of new radio (NR) links of a E-UTRAN new radio (NR) dual connectivity (EN-DC) comprising a first radio access technologies (RAT) and a second, different RAT. A first link quality metric (LQM) evaluation of the first RAT is generated independently of generating a second LQM evaluation of the second RAT. A radio frequency (RF) interface, is configured to provide, to RF circuitry, data for a transmission of the first LQM evaluation and the second LQM evaluation based on a data split at a protocol layer so that a network component of base station can utilize the data to configure a data flow over the links based on link quality metrics provided.

Abstract: A wireless communication system is presented for robust mobility management in a HetNet communication system. A source cell can prepare a macro cell and a target small cell as handover candidates during handover decision making and/or preparation. The mobile device is informed about the prepared macro cell and target small cell using radio resource control (RRC) messaging. After receiving a handover command or detecting radio frequency (RF) loss, the mobile device can try to connect with the target small cell. If the mobile device is unable to connect to the target small cell, the UE can fall back and connect to the macro cell.

Abstract: A device and method selects an antenna configuration. The method performed at a user equipment includes determining at least one communication functionality that is being used, each communication functionality configured to utilize at least one antenna in a multi-antenna arrangement of the user equipment. The method includes receiving a first indication of whether a cellular communication functionality is being used, the cellular communication functionality configured to utilize at least one antenna in the multi-antenna arrangement. The method includes receiving a second indication of whether a coexistence condition is present. The method includes determining an antenna configuration for the multi-antenna arrangement to be used by the determined communication functionality based upon the determined communication functionality, the first indication, and the second indication. The method includes configuring the multi-antenna arrangement for the determined communication functionality based upon the antenna configuration.

Abstract: A wireless communication system is presented for multiple wireless technology coexistence in a mobile device. A method according to this application might include obtaining one or more transmit allocation parameters for a wireless transmission via a first radio technology at a first wireless processor and the preparing to receive wireless data via a second radio technology at a second wireless processor. Next, the exemplary method might request that the wireless transmission be deferred, followed by deciding whether to grant the deferral request based at least on the one or more transmit allocation parameters.

Abstract: A client device and a host device may create a local connection for providing wide area network access, such as Internet access, to the client device. In some embodiments, the client device may have limited network capabilities and may not be able to access the Internet without the host device. The client device may provide its speed and direction in a message to potential host devices. A host device may calculate a suitability metric, based on the speed and direction of the client as well as connection properties of the networks, which indicates an ability for the host device to connect the client device to the Internet. The host device may provide the suitability metric within a connection request to the client device. Based on the suitability metric and/or other factors, the client device and the host device may establish the local connection.

Abstract: This disclosure relates to performing antenna selection to reduce interference in a wireless device. According to some embodiments, it may be determined whether simultaneous communication according to first and second wireless communication technologies causes performance degradation to a third wireless communication technology. If the simultaneous communication according to first and second wireless communication technologies does cause performance degradation to the third wireless communication technology, selection of antenna(s) used for the communications may be based at least in part on the determination that the simultaneous communication according to the first and second wireless communication technologies causes performance degradation to the third wireless communication technology.

Abstract: Carrier aggregation using unlicensed frequency bands. A primary carrier for communication between a base station (BS) and a wireless user equipment (UE) device may be configured according to a first wireless communication technology. The primary carrier may be on a licensed frequency band. A secondary carrier for communication between the BS and the UE may also be configured according to a first wireless communication technology. The secondary carrier may be on an unlicensed frequency band. Channel conditions for each of multiple possible channels of the unlicensed frequency band may be assessed according to a second wireless communication technology as part of configuring the secondary carrier.

Abstract: A method for controlling transmission power in accordance with a total transmission power limit in a multi-radio wireless communication device including a master radio and a slave radio is provided. The method can include the wireless communication device determining, at the master radio, a transmission power of the master radio. The method can further include the wireless communication device providing information indicative of the transmission power of the master radio from the master radio to the slave radio. The method can additionally include determining, at the slave radio, an allowable transmission power for the slave radio. A sum of the allowable transmission power and the transmission power of the master radio may not exceed the total transmission power limit.
