Abstract: Methods, systems, and apparatuses (including, but not limited to, User Equipment (UE) and Base Stations) for a UE to control a packet header compression function in a communication system are described. In one method, if a predetermined condition is satisfied while the packet header compression function is enabled, the UE transmits a request for disabling the packet header compression function to a Base Station (BS), and, if a response is received from the BS, the UE disables the packet header compression function.

Abstract: Disclosed are a method and apparatus for packet communication using header compression. The method includes applying a header compression protocol to generate a packet to be transmitted, determining whether the packet is dropped in a transport layer, and transmitting, if it is determined that the packet is dropped, a full packet having an uncompressed header.

Abstract: A mobile terminal for supporting Rich Communication Suite (RCS) and Voice Over Long Term Evolution (VoLTE) based services is provided. The mobile terminal includes an application processor that enables a first layer of a first session connection protocol stack and transmits signaling for an RCS service to a modem processor; and the modem processor that comprises a second session connection protocol stack for connecting a session, and that transmits, to a communication network, the signaling for the RCS service transmitted through the first layer.

Abstract: An apparatus and a method for generating an Automatic Repeat reQuest (ARQ) feedback message in a wireless communication system are provided. The method includes generating first feedback information of at least one ARQ block, determining whether any ARQ blocks include at least one successfully received ARQ sub-block, when the at least one erroneous ARQ block includes at least one successfully received ARQ sub-block, adding second feedback information of the ARQ sub-blocks to the first feedback information of the ARQ blocks using a field indicating whether the second feedback information is added and a field indicating the erroneous ARQ blocks including the at least one successfully received ARQ sub-block, and sending the first feedback information with the second feedback information added, to the transmitting stage.

Abstract translation: 提供了一种用于在无线通信系统中生成自动重复请求（ARQ）反馈消息的装置和方法。 该方法包括当至少一个错误的ARQ块包括至少一个成功接收到的ARQ子块时，生成至少一个ARQ块的第一反馈信息，确定任何ARQ块是否包括至少一个成功接收的ARQ子块， 使用指示是否添加第二反馈信息的字段和指示包括至少一个成功接收的ARQ子块的错误ARQ块的字段，ARQ子块的第二反馈信息到ARQ块的第一反馈信息，以及 将第一反馈信息与添加的第二反馈信息发送到发送阶段。
