摘要： Embodiments contemplate devices and techniques for receiving unicast and multicast transmissions over a downlink (DL) shared channel in parallel, for example an LTE DL shared channel (SCH). For example, one or more hybrid automatic repeat request (HARQ) entities may be configured to perform retransmissions of the multicast and/or unicast messages. Common and/or dedicated (e.g., separate) HARQ entities may be utilized for retransmission. The multicast downlink shared channels may be activated and/or deactivated on demand. The activation and/or deactivation may be performed using radio resource control (RRC) signaling and/or Medium Access Control (MAC) signaling. The multicast and/or unicast downlink shared channel data may include scalable video coding (SVC) data of varying priority. Embodiments also contemplate the use of simultaneous (e.g. parallel) multicast/unicast for scalable video coding transmission over WiFi/802.11 protocol signals.

摘要： Methods, apparatuses and systems for performing hierarchical traffic differentiation and/or employing hierarchical traffic differentiation are provided. These methods, apparatuses and systems may be implemented to, for example, handle congestion and/or to manage user quality of experience (QoE). Performing the hierarchical traffic differentiation may include differentiating or otherwise classifying (collectively “differentiating”) traffic mapped to, or within, a bearer formed in accordance with a QoS class into multiple traffic sub-classes. Employing the hierarchical traffic differentiation may include scheduling and/or policing (e.g., filtering) the differentiated traffic for transmission based on a prioritization of, and/or policy for managing, the multiple traffic sub-classes.

摘要： A device may control a video communication via transcoding and/or traffic shaping. The device may include a multipoint control unit (MCU) and/or a server. The device may receive one or more video streams from one or more devices. The device may analyze a received video stream to determine a viewing parameter. The viewing parameter may include a user viewing parameter, a device viewing parameter, and/or a content viewing parameter. The device may modify a video stream based on the viewing parameter. Modifying the video stream may include re-encoding the video stream, adjusting an orientation, removing a video detail, and/or adjusting a bit rate. The device may send the modified video stream to another device. The device may determine a hit rate for the video stream based on the viewing parameter. The device may indicate the bit rate by sending a feedback message and/or by signaling a bandwidth limit.

摘要： HARQ parameters (e.g., maximum HARQ retransmission values) may be adapted. Cross-layer control and/or logical channel control may be used to select a maximum number of HARQ retransmissions, for example based on packet priority and/or QCI values. Respective priorities of video packets may be used to select one of a plurality of logical channels associated with a video application that may be established at a source wireless hop and/or a destination wireless hop. The logical channels have different HARQ characteristics. Different maximum HARQ retransmission values may be determined for select logical channels, for example such that packets of different priorities may be transmitted over different logical channels. One or more of the channels may be associated with one or more transmission queues that may have different priority designations. Video packets may be reordered (e.g., with respect to transmission order) within the transmission queues, for example in accordance with respective HARQ parameters.
摘要翻译： HARQ参数（例如，最大HARQ重传值）可以被适配。可以使用跨层控制和/或逻辑信道控制来例如基于分组优先级和/或QCI值来选择最大数量的HARQ重传。可以使用视频分组的各个优先级来选择与在源无线跳和/或目的地无线跳跃建立的视频应用相关联的多个逻辑信道之一。逻辑信道具有不同的HARQ特性。可以为选择的逻辑信道确定不同的最大HARQ重传值，例如使得不同优先级的分组可以在不同的逻辑信道上传输。一个或多个信道可以与可能具有不同优先级指定的一个或多个传输队列相关联。可以例如根据相应的HARQ参数，在传输队列内对视频分组进行重新排序（例如，关于传输顺序）。
