摘要： 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.

摘要： Methods and apparatus to mitigate interference among multiple wireless subsystems of a wireless communication device are described. A host processor obtains configurations for a plurality of wireless subsystems and evaluates whether potential or actual coexistence interference exists between two or more of the wireless subsystems. The host processor provides configuration information and link quality reporting parameters to and obtains link quality reports from at least two wireless subsystems. When link quality for at least one wireless subsystem fails a set of link quality conditions, the host processor adjusts data requirements for applications that communicate through one or more of the wireless subsystems and/or adjusts radio frequency operating conditions for one or more of the wireless subsystems to mitigate interference among the wireless subsystems.

摘要： In video conferencing over a radio network, the radio equipment is a major power consumer especially in cellular networks such as LTE. In order to reduce the radio power consumption in video conferencing, it is important to introduce an enough radio inactive time. Several types of data buffering and bundling can be employed within a reasonable range of latency that doesn't significantly disrupt the real-time nature of video conferencing. In addition, the data transmission can be synchronized to the data reception in a controlled manner, which can result in an even longer radio inactive time and thus take advantage of radio power saving modes such as LTE C-DRX.

摘要： A method and apparatus for forced cell/RAT reselection is disclosed. In one embodiment, a cellular mobile communication device may attempt to access a network through a serving cell. Responsive to determining that access to the network is barred through the serving cell, the mobile communication device may determine if another cell is available through which it may obtain access to the network. If another cell providing network access is available, the mobile communication device may force reselection from the serving cell to the new cell. If no other cell providing access to the network is available to the mobile communication device, a forced reselection of a radio access technology may be performed.

摘要： 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.

摘要： 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.

摘要： 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.
