The invention relates to a control channel signal for use in a mobile communication system providing at least two different scheduling modes. Further the invention relates to a scheduling unit for generating the control channel signal and a base station comprising the scheduling unit. The invention also relates to the operation of a mobile station and a base station for implementing a scheduling mode using the control channel signal. In order to facilitate the use of different scheduling schemes for user data transmission while avoiding an additional flag for indicating the scheduling mode in the control signaling, the invention proposes the use of code points in existing control channel signal fields. Further, the invention proposes a specific scheduling mode for use in combination with the proposed control channel signal. According to this scheduling mode control channel information is only provided for retransmissions, while initial transmissions are decoded using blind detection.

A method for a transmission-side device to transmit a signal in a wireless communication system is disclosed. To this end, the transmission-side device forms a multiplexed block by multiplexing a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH) signal in time and frequency domains, wherein the PSS and the SSS form a synchronization signal (SS) by being multiplexed by the time-division multiplexing (TDM) method, and the SS and PBCH signals form the multiplexed block by being multiplexed by the TDM or frequency-division multiplexing (FDM) method.

A distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas. The cellular band outputs of these microcell base station devices are used to modulate a 60 GHz (or higher) carrier wave, yielding a group of subcarriers on the 60 GHz carrier wave. This group will then be transmitted in the air via analog microwave RF unit, after which it can be repeated or radiated to the surrounding area. The repeaters amplify the signal and resend it on the air again toward the next repeater. In places where a microcell is required, the 60 GHz signal is shifted in frequency back to its original frequency (e.g., the 1.9 GHz cellular band) and radiated locally to nearby mobile devices.

A method, an apparatus, and a computer program for wireless communication that allows for greater scheduling flexibility of physical resources are disclosed. A UE receives information from a base station about a time division duplex (TDD) frame structure of a plurality of frames that include a plurality of subframes. The UE determines a control channel search space within the plurality of subframes based on the information. The UE determines a search strategy including a maximum aggregation level based on the control channel search space. The UE performs a blind decoding of the control channel search space with the search strategy to obtain control information. The control channel search space may include a size and a location of a subset of the DL subframes allowed to carry the control information. The UE may determine a plurality of UL subframes assigned for transmitting scheduled UL resources associated with a UL control signaling.

There is provided a method of implementing carrier aggregation on a first transceiver. The method comprises receiving and decoding, during a first subframe, channel quality information from user equipment and transferring, before the expiry of a second subframe immediately following the first subframe, the decoded channel quality information over a direct physical link to a second transceiver, for use in decoding further channel quality information from the user equipment.
