Abstract: Disclosed is a method and system for managing carriers on which a wireless communication system serves a UE. As disclosed, the system serves the UE on a set of one or more carriers. While serving the UE on the set of one or more carriers, the system determines that the UE should additionally be served on at least one other carrier. The system then selects the at least one other carrier, from a set of candidate carriers, based at least in part on the at least one other carrier being closest, of the set of candidate carriers, in the frequency spectrum to the set of one or more carriers. Based on the selecting, the system then adds the selected at least one other carrier to the set of one or more carriers to establish a modified set of carriers and serves the UE on the modified set of carriers.

Abstract: Disclosed is a method and system to help facilitate transition from broadcast to unicast. A broadcast server provides a copy of session content to a unicast gateway, and a content-synchronizer keeps track of which UEs are broadcast recipients and what the progress of the broadcast is over time. In response to unicast attachment of a UE with the unicast gateway, as when the UE moves from broadcast coverage to unicast coverage, the unicast server determines based on information from the content synchronizer (i) that the UE is a broadcast recipient and (ii) the progress of the broadcast so far. The unicast gateway then begins transmitting to the UE the media content received from the broadcast server, starting at a point in the media content based on the determined progress. This process may thereby help to facilitate a seamless transition from broadcast to unicast, with at most a brief interruption.

Abstract translation: 公开了一种帮助促进从广播转到单播的方法和系统。 广播服务器向单播网关提供会话内容的副本，并且内容同步器跟踪哪些UE是广播接收者，以及广播的进展是否随时间而变化。 响应于UE与单播网关的单播连接，当UE从广播覆盖范围移动到单播覆盖时，单播服务器基于来自内容同步器（i）的信息来确定UE是广播接收者，并且（ii） 到目前为止播出的进度。 然后，单播网关开始从广播服务器接收的媒体内容，基于所确定的进度从媒体内容的一个点开始传送。 这个过程可能有助于促进从广播到单播的无缝转换，最多只是一个短暂的中断。

Abstract: Disclosed is a method and system to facilitate management of resources in a scenario where a base station has an established radio-link-layer connection for serving a device on multiple component carriers. Rather than providing all bearer data transmission to the device by rote on the multiple component carriers, the base station dynamically decides per data whether to transmit the data to the device on the multiple component carriers or rather on just one of the component carriers. For instance, when the base station receives data for transmission over the radio-link-layer connection to the device, the base station determines based on at least one characteristic of the data whether to transmit the data to the UE on the multiple component carriers or rather on just one of the component carriers, and the base station then schedules and engages in the transmission in accordance with that determination.

Abstract: A base station and a user equipment (UE) device may communicate over an air interface in a particular time division duplexing (TDD) configuration. The TDD configuration specifies a certain number of consecutive subframes for uplink communications and a certain number of consecutive subframes for downlink communications. A transmitter (either the UE device or the base station) may transmit data using transmission time interval (TTI) bundling with a bundle size of N. To select a set of N subframes to use to transmit the data, the transmitter may compare N to C, the number of consecutive subframes available to transmit the data. If N≤C, the N subframes in the set are consecutive subframes. If N>C, the set of N subframes includes C consecutive subframes and at least one additional subframe that is separated from the consecutive subframes by one or more subframes not in the set.

Abstract: A controller may use allocate a set of carriers between two or more base stations based on the respective backhaul capacities of the base stations. An example method involves determining a first backhaul capacity of a first base station, determining a second backhaul capacity of a second base station, and allocating carriers of a set of carriers between the first base station and the second base station based at least one a comparison between the determined first backhaul capacity and the determined second backhaul capacity.
