摘要： A method performed by a network node (203a, 400, 500) for providing pre-grant assistance for a communication device (101, 300) having multi connectivity over two or more legs (205a, 205b) to two or more network nodes (203a, 203b) of a communications network (201) is provided. The method includes determining a pre-grant assistance information for the communication device based on at least one of (i) a status of a radio resource management function and any other pre-grant assistance information sent by the network node to other communication devices connected to the network node and (ii) information received from other network nodes. The pre-grant assistance information includes a value for a future grant to the communication device per leg of the two or more legs. The method further includes transmitting to the communication device an indication including the pre-grant assistance information per leg of the two or more legs.

摘要： A network node 606,608 and a method for Packet Data Convergence Protocol (PDCP) reordering. The network node is operating in a wireless communications network 600. The network node buffers in order one or more first data units received out of order by a PDCP layer, wherein the one or more first data units are received from a lower layer during a first time period, and wherein the lower layer is a layer below the PDCP layer. When the first time period has expired, the network node forwards the one or more buffered first data units in order to an upper layer and starts a second time period. Further, the network node forwards, to the upper layer and in any order, one or more second data units received from the lower layer during the second time period.

摘要： A receiver (100) includes a detector (140) for detecting a change in source of incoming media during an on-going communication session, and means to provide a reset signal in order to reset decoder states of a decoder (120) in response to such a detected change before decoding new incoming media. In this way, a state mismatch can be avoided without the need for several active decoder instances in the receiver (100), leading to substantial savings with respect to overall complexity, memory usage and power consumption. This also means that media distortions can be eliminated or at least reduced when the decoded media is finally rendered by a player (130).
摘要翻译：接收器（100）包括用于在正在进行的通信会话期间检测输入媒体的源中的改变的检测器（140），以及用于提供重置信号以重置解码器状态的装置解码器（120）响应于在解码新的传入媒体之前检测到的这种变化。以这种方式，可以避免状态失配，而不需要接收器（100）中的几个活动解码器实例，从而导致整体复杂度，存储器使用和功耗相当大的节省。这也意味着当解码媒体最终由玩家呈现时可以消除或至少减少媒体失真（130）。

摘要： A method and a communication station (5) for determining a packet format of a data packet based on at least one compressed header information field. A header packet format of a data packet is determined based on the determined packet format of a partially or completely compressed header information part. The station may also determine a codec rate (10) based on the result of a previously performed compression of at least one header information field. In one embodiment, internal cross-layer signaling from a header generator module (6) to a payload generator module (7) in the communication station is used for signaling information associated with determining the header packet format of the data packet. The method reduces bandwidth fluctuations associated with services such as text messaging, audio, or audiovisual services; lowers the delay variations and the erasure rates for application media streams; and provides for faster set-up of sessions.

摘要： A method performed by a Distributed Unit (DU) for managing packets in a wireless communication network is provided. The DU determines a load in a buffer; and marks a packet from a Central Unit (CU), with a first indication related to end-to-end latency due to the determined load in the buffer. The DU then transmits the packet with the first indication to a UE; and transmits to the CU, a second indication indicating a probability that packets are marked from the UE.

摘要： In a method of improved media frame transmission in a communication network. Initially a plurality of "original" or regular media frames are provided for transmission. According to the invention, robust representations of the provided regular media frames are generated and stored locally. Subsequently, one or more of the regular media frames is/ are transmitted. The invention detects an indication of a loss of a transmitted media frame, and the idea is to transmit, in response to a detected frame loss, a stored robust representation of the lost media frame and/ or a stored robust representation of a subsequent, not yet transmitted, media frame to increase the media quality.
