The method includes determining a characteristic related to a receipt of a resource allocation in a particular subframe and, based on the determined characteristic, selecting one of a plurality of transmit antennas for use in transmitting to a wireless network node. A wireless network node that is configurable to operate with the user equipment to signal the resource allocation of the indication of the transmit antenna to be used is also disclosed. | 05-06-2010 |
| 20100142474 | SCHEDULING REQUEST TRANSMISSION SUPPORTING HIGH DOPPLER - Block spreading generating partial orthogality is applied for the uplink control channel for E-UTRA. For instance, a problem of maximizing the multiplexing capacity leads to numerology causing odd-length sequences which do not have the favorable property of even-length sequences (partial orthogonality). The consequence of this is poor performance in cases of high Doppler effects. Maximal multiplexing capacity is taught without loss of performance at high Doppler by modifying an earlier scheduling request (SR) scheme. The earlier SR multiplexing scheme has a number of parallel SR resources per slot equal to 12*7=84. In one example, the spreading factor of block spreading is changed to an even number, e.g., from 7 to 6. This enables usage of the partial orthogonality properties of CAZAC sequences and as a result inter-code interference in the case of high Doppler is reduced. Other ways to generate partial orthogonality are shown with similar results. | 06-10-2010 |
| 20100189051 | DATA MODULATION IN A COMMUNICATION SYSTEM - A modulator and a modulation method for a communication device are disclosed.

| 20100248736 | Inter-System Interference Control - It is provided a solution for controlling interference in a cellular telecommunication system. An interference controller of the cellular telecommunication utilizes interference level information received from another cellular telecommunication system in controlling interference towards a target cell suffering from high interference which degrades the grade of service in the target cell. The interference level information comprises information on levels of interference between neighboring cells of the other cellular telecommunication system. The interference controller analyzes the received interference level information and controls communication links in cells of the cellular telecommunication system determined to cause the highest interference towards the target cell. The cells determined to cause the highest interference towards the target cell are determined from the received interference level information. | 09-30-2010 |
