    • Data for a multicast service is provided by a radio communication system by performing header compression and employing a packet data convergence protocol (PDCP) entity that exists for every specific MBMS service to be provided for a cell with users therein. The particular network component (e.g., in a SRNC or a CRNC) that includes one PDCP layer for each specific MBMS service depends upon certain characteristics of the terminals (UE) located within a cell that wish to receive the specific MBMS service. The terminal receives via a common transport channel and restores (i.e., decompresses) the header-compressed data of the MBMS service that was transmitted after header compression at the CRNC, while the terminal receives via a dedicated transport channel and restores (i.e., decompresses) the header-compressed data of the MBMS service that was transmitted after header compression at the SRNC.
    • 多播服务的数据由无线电通信系统提供,通过执行报头压缩,并采用为每个特定的MBMS服务存在的分组数据汇聚协议(PDCP)实体,为其中的用户提供一个小区。 包括用于每个特定MBMS服务的一个PDCP层的特定网络组件(例如,在SRNC或CRNC中)取决于位于希望接收特定MBMS服务的小区内的终端(UE)的某些特性。 终端通过公共传输信道接收,并且在终端经由专用传输信道接收并恢复(即,解压缩)之后,恢复(即,解压缩)在CRNC的报头压缩之后发送的MBMS服务的报头压缩数据, 在SRNC的报头压缩之后发送的MBMS服务的报头压缩数据。

    • A method for controlling the transmission of signals in a communications system uses a polling trigger which prevents a deadlock condition from occurring between a transmitter and receiver. The method includes selecting a protocol data unit from a buffer, determining whether the data unit is located at a predetermined position within a transmission window, and then transmitting polling information with the data unit if the data unit is determined to be at the predetermined position of the transmission window. The predetermined position is preferably a last position of the window. If the data unit is not in a last position of the transmission window, additional steps of the method include determining whether the data unit is a last-stored data unit in a transmission buffer. If so, polling information is transmitted with the data unit. If neither polling trigger is satisfied, the data unit is transmitted without polling information. The method may at least partially be performed within a radio link control layer of the transmitter operating in acknowledged mode. A user terminal or network apparatus may include a computer program for performing the steps of the method. By controlling the transmission of polling information based on the aforementioned triggers, a deadlock condition is advantageously prevented. As a result, the efficiency and the reliability of communications is substantially improved.
