TL;DR: In this article, the authors propose a protocol for transmitting and receiving downlink control information (DCI) in a single cell in order to support communication over multiple cells, where the DCI is conveyed by DCI formats transmitted through PDCCHs in a UE-Common Search Space (UE-CSS) and in a UEspecially designated search space (U-Dedicated Search Space).

TL;DR: In this article, an improved power control method and apparatus of a mobile terminal is provided for facilitating random access procedure in a mobile communication system based on a distributed antenna system, which includes receiving, by the terminal, system information from a base station, the system information including transmit power information for transmitting a random access preamble; calculating a transmit power using the transmitted power information; and transmitting the random access precamble using with the calculated transmit power.

TL;DR: In this article, an uplink power control method and apparatus of a terminal in a mobile communication system are provided, which includes receiving, by the terminal, a location parameter corresponding to at least one antenna selected among a plurality of antennas distributed in a service area of a base station, each of which being connected to the base station.

TL;DR: In this paper, a control information transmission and reception method based on a spatial-multiplexing gain was proposed, where the common control information used for decoding the E-PDCCH was transmitted via a PDCCH, and thus, a base station supporting both a general terminal and an enhanced terminal may effectively transmit the control information.

TL;DR: In this paper, the authors propose a scheme for dynamic activation and deactivation of Sounding Reference Signal (SRS) transmissions from user equipments (UEs) in an UL component carrier (CC) with configured SRS transmissions.
