20080225816 | Interface, Apparatus, and Method for Communication Between a Radio Equipment Control Node and a Remote Equipment Node in a Radio Base Station - An interface, apparatus, and method are described for communication between a radio equipment control (REC) node and a radio equipment (RE) node in a radio base station that tranceives information over radio interface using multiple antenna carriers. The REC node is separate from and coupled to the RE node by a transmission link. Both control information and user information are generated for transmission over the transmission link from one of the REC node and the RE node to the other. Many advantageous interface features are described. | 09-18-2008 |
20080287132 | Method, Computer Program And Base Station For Prediction Based Allocation Of Processing Resources In A Non-Serving Base Station - The present invention relates to a base station and a method in a mobile telecommunication network for allocating and de-allocating uplink base station processing resources to a mobile terminal. The base station are adapted to communicate to a mobile terminal on an uplink channel supporting macro-diversity, and the base station is adapted to be a non-serving base-station without control of the resource allocation to the mobile-terminal. The base station comprises means for predicting a likelihood of successful decoding of a future transmission, and means for allocating or de-allocating processing resources based on said prediction. | 11-20-2008 |
20110009157 | METHOD AND ARRANGEMENT IN A WIRELESS COMMUNICATION NETWORK - The present invention relates to a method and arrangement for reducing interference in a cellular communication network.

20120063294 | Method for a Radio Base Station and a Radio Base Station in a Communication Network System for Assisting in or Obtaining Assistance in the UL Reception of Signals - In cellular radio systems it is a problem to provide service to UE (user equipment) on the cell border. In systems that apply a frequency re-use of one, and OFDM access technology, the uplink direction need be improved. One embodiment of this application relates to a radio base station that is equipped with one or more FFT processor/s in addition to the FFT-processor that is adapted for being adjusted to the timed aligned arrival of signals from UE served by the radio base station. The additional FFT processor/s is adapted for being adjusted to the arrival of one or more signals from UE that are served by other radio base station/s. The radio base station is further adapted to send Fourier processed signal information relating to the UE of the other radio base station/s and thereby assist the other radio base station in signal reception. The application also relates to a method for assisting another radio base station in signal reception, and to a method for receiving assistance from another radio base station in signal reception. | 03-15-2012 |

20140269409 | EXPLICIT SIGNALING OF NUMBER OF RECEIVER ANTENNAS - Systems and methods for explicitly signaling a number of receiver antennas of one node in a cellular communications network to another node in the cellular communications network are disclosed. In one embodiment, a first node in the cellular communications network sends a number of receiver antennas of the first node to a second node in the cellular communications network. In one embodiment, the first node broadcasts the number of receiver antennas of the first node. In another embodiment, the first node unicasts the number of receiver antennas of the first node to the second node. The second node then utilizes the number of receiver antennas of the first node to perform a desired action. | 09-18-2014 |
20150023235 | Flexible Downlink Subframe Structure for Energy-Efficient Transmission - Disclosed herein are methods for using new energy-saving subframe structures, as well as corresponding apparatus that are configured to exploit these energy-saving subframes. In these energy-saving subframes, some, but not all, of the individual OFDM symbols in a subframe are inactive, meaning that no signal is transmitted during at least a part of the symbol time of the blanked symbols. An example method according to these techniques may be implemented in a radio transceiver, such as an LTE eNodeB, and comprises transmitting, in a first symbol time of a downlink subframe that comprises a plurality of symbol times, a codeword indicating that the downlink subframe includes at least one inactive symbol time. The method further includes transmitting data during at least one but fewer than all of the remaining ones of the plurality of symbol times in the downlink subframe. Corresponding techniques for receiving the energy-saving subframes are also disclosed. | 01-22-2015 |
