Abstract: A method and apparatus are provided for controlling an active state in a mobile communication system. The method includes receiving, from a base station, information related to a starting position of an active state and information related to a length of a first timer; deriving the starting position of the active state based on the information related to the starting position; starting the first timer set to the length of the first timer and entering the active state at the derived starting position; extending the active state, in response to control data indicating a new transmission of user data being received on a control channel; and terminating the active state, based on a control signal indicating a termination of the active state and a second timer for extending the active state. The second timer is started while the first timer is running, and the active state is terminated by the expiration of the second timer.

Abstract: A method and apparatus are provided for transmitting power headroom information by a terminal in a mobile communication system. The method includes receiving, by the terminal, information for an allocated uplink transmission resource; identifying whether a path loss has changed by more than a threshold, after transmitting last power headroom information, when the terminal has the allocated uplink transmission resource; in case that the path loss has changed by more than the threshold when the terminal has the allocated uplink transmission resource, determining a transmission of the power headroom information; and transmitting an uplink packet including the power headroom information based on the allocated uplink transmission resource. The power headroom information is obtained based on a difference between a maximum transmission power of the terminal and a transmission power of the terminal.

Abstract: A user equipment (2) has an ability to operate according to one or more spectrum emission requirement capability values (14) in a wireless communications network having at least a first serving cell (4). A message (6) is received at the user equipment (2) from the first serving cell (4) comprising a first indicator representing a first band designation (8), a second indicator representing a spectrum emission requirement value (10), and at least one additional indicator representing at least one additional spectrum emission requirement value (12), both the first and additional indicators relating to the first band designation. The user equipment (2) performs a comparison of the first and additional spectrum emission requirement values (10, 12) with the one or more spectrum emission requirement capability values (14) and determines a behaviour of the user equipment (2) in relation to the first serving cell (4) in dependence on the comparison.

Abstract: Methods and apparatuses are provided for transmitting a status report by a receiving device including an automatic repeat request (ARQ) entity and a hybrid ARQ (HARQ) processor, in a mobile communication system. The method includes receiving, by the ARQ entity, a packet from a transmitting device through the HARQ processor; determining, by the ARQ entity, whether a status report is triggered based on at least one triggering condition; generating, by the ARQ entity, the status report including a reception status of the received packet at a transmission opportunity indicated by the HARQ processor, in response to the status report being triggered; and transmitting, by the HARQ processor, to the transmitting device, a packet including the status report.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). Next generation of wireless cellular operation is expected to be deployed in higher frequency above 6 GHz (eg. 10 GHz˜100 GHz, also called mmWave and/or cmWave) due to availability of large amount of spectrum bandwidths. The physical layer of wireless cellular system in both DL and UL operating in mmWave/cmWave would be based on new air-interface different from that of LTE-A air-interface because the radio characteristics is different for mmWave/cmWave bands. The initial deployment of mmWave/cmWave system is expected to operate as non-standalone system to provide additional radio resources to the UE which would be connected to the LTE-A cell for coverage purpose. The present disclosure covers initial access aspects of a UE on such future wireless system.

Abstract: The present invention relates to a method and apparatus for transmitting data using a multi-carrier in a mobile communication system. The method of transmitting data in user equipment of a wireless communication system using a carrier aggregation technique according to an embodiment of the present invention includes the steps of setting secondary cells included in an S-TAG (Secondary-Timing Advance Group) configured of only secondary cells (SCells), deactivating a downlink timing reference cell in the S-TAG; determining whether other activated secondary cells exist besides the deactivated downlink timing reference cell in the S-TAG, and when the other activated secondary cells exist in the S-TAG, setting one of the other activated secondary cells as a new downlink timing reference cell. According to the present invention, uplink transmission speed can be increased in the user equipment and user QoS can be improved by transmitting data using one or more uplink carriers in the terminal.
