Abstract: The present disclosure relates to communication schemes for combining 5G communication systems with IoT technology to support higher data transmission rate as post-4G systems and systems for the same. The present disclosure may be used in intelligent services (e.g., smart home, smart building, smart city, smart car, or connected car, health-care, digital education, retail business, security and safety-related services, etc.) based on the 5G communication technology and IoT-related techniques. Disclosed is a method for transmitting a scheduling request (SR) by a user equipment (UE) in a cellular communication system. The transmitting method may comprises receiving configuration information related to transmission of the SR from an enhanced node B (eNB), determining a value of a timer for prohibiting an SR transmission based on the received configuration information, and transmitting a set of SRs, wherein the timer may start at the time of transmission of a first SR of the SR set.

Abstract: A method and apparatus for controlling measuring the frequency of a new cell within a forbidden registration area when a User Equipment (UE) enters into the new cell in a mobile communication system are provided. If the UE recognizes the new registration area as forbidden, the UE does not measure the frequency of the current cell for a predetermined reference time, and searches for a suitable cell for a normal service by measuring other frequencies. If no suitable cell in the other frequencies is found, the UE removes a measuring limitation and searches for an acceptable cell for a limited service by measuring frequencies including frequency of the current cell.

Abstract: Improving communication efficiency in handover re-establishing an ARQ entity in a mobile communication system is disclosed. The method includes transmitting first Packet Data Convergence Protocol (PDCP) Packet Data Units (PDUs) correctly received from the source cell, together with a special indication requiring reordering of the first PDCP PDUs, from a Radio Link Control (RLC) receiving buffer to a PDCP receiving entity when a handover command message from a source cell to a target cell is received; buffering the first PDCP PDUs in a PDCP PDU reordering buffer by the PDCP receiving entity in response to the special indication; and when a second PDCP PDU is received from the target cell through a new RLC receiving entity for the target cell, outputting third PDCP PDUs up to a PDCP PDU before a first missing PDCP PDU having a sequence number higher than that of the second PDCP PDU from the PDCP reordering buffer. In the method, a PDCP entity performs reordering, thereby improving efficiency of communication.
