Abstract: The present disclosure relates to a 5G or pre-5G communication system which will be provided in order to support a higher data transmission rate than a 4G communication system such as LTE. In addition, a method for transmitting and receiving signals in a terminal of a mobile communication system, according to one embodiment of the present specification, comprises the steps of: receiving, from a base station, control information including scheduling information about a plurality of subframes; transmitting data to the base station or receiving data from the base station through resources decided based on the control information; and receiving, from the base station, feedback information about the transmitted data, or transmitting, to the base station, feedback information about the received data. According to one embodiment of the present specification, there is an effect of reducing overhead of a base station, a resource and a channel according to resource allocation by performing, at one time, resource allocation for a plurality of transmission time intervals. In addition, communication efficiency is increased by performing, in one subframe, resource allocation for one or more transmission time intervals, and when feedback thereon is received, performing an operation for each of a plurality of processes.

Abstract: A method and system for providing selective protection of data exchanged between user equipment (UE) and network is disclosed. The selective protection is applied to a packet, a bearer or an access point name for secure exchange of data between the UE and the network. The network decides to apply selective protection based on configuration of network, configuration of UE, load in the network, battery power availability of UE, type of application running on UE. Further, the UE can request for selective protection based on the type of application running on UE and the battery level availability of the UE. The selective protection is either enabled or disabled dynamically by the network. Further, various mechanisms for applying selective protection for each bearer, each packet and each Access Point Name (APN) are disclosed. Additionally, the method for identifying a secured and a non secured bearer has also been disclosed.

Abstract: An apparatus and a method for Automatic Repeat reQuest (ARQ) feedback in a wireless communication system are provided. A method for the ARQ feedback at a receiving end includes when receiving an ARQ block from the transmitting end, checking for error in the ARQ block, when the ARQ block has no error, initializing and driving a timer used for determining whether to perform the ARQ feedback according to reception of a next ARQ block, when receiving the next ARQ block without error before the timer expires, initializing and driving the timer, and when the timer expires, performing the ARQ feedback in relation to at least one ARQ block received without error.
