    摘要: Methods and devices are provided whereby scrambling codes can be set in an improved way. In accordance with one embodiment a method is provided in a User Equipment for generating a second scrambling code or a second scrambling code group. The UE is configured for multi carrier operation receiving downlink transmission from a Universal Mobile Telecommunications System Terrestrial Radio Access Network on a set of at least two downlink carriers including an anchor carrier and at least a first secondary carrier. The method comprises determining a first scrambling code or a first scrambling code group associated with a first cell on the anchor carrier; and deriving a second scrambling code or a second scrambling code group associated with a second cell on said first secondary carrier using a predefined rule defining the relation between the second scrambling code or second scrambling code group and the first scrambling code or scrambling code group. Hereby interference suppression/cancellation processing is enabled in a receiver of a UE on secondary cells in multi-carrier scenarios that do not transmit the SCH, while minimizing the need for overhead in terms of signaling of the scrambling codes for neighbouring cells in a UTRAN system. Methods and devices for E-UTRAN are also described.

    摘要: Methods and devices are provided wherein a user equipment transmits using at least two uplink transmit antennas and receives a set of control signals in the downlink direction from a cellular network. The user equipment estimates a received signal quality for each control signal in said set of control signals and determines, based on said received signal quality, which control signals that have been reliably received. The user equipment derives one or more parameters related to the uplink transmit diversity operation using a subset of control signals from the set of control signals, said subset only including control signals determined as reliably received; and transmits in the uplink direction applying the derived one or more parameters to control the uplink transmit diversity operation. The accuracy of the transmit diversity parameter values derived/set by the UE can be improved. This will enhance the performance of the uplink transmit diversity and will also reduce interference to the neighbor cells.

    摘要: A multi-carrier linear equalization receiver, e.g., a RAKE receiver or chip equalization receiver, is described herein. The multi-carrier receiver distributes processing delays among a plurality of received carriers based on a dispersion determined for each carrier. The receiver initially allocates a minimum number of processing delays sufficient for light dispersion to each carrier. For the dispersive carriers, the receiver allocates one or more additional processing delays. In one embodiment, the additional processing delays are allocated to the dispersive carriers based on SIR.

    摘要: A radio receiver receives multiple radio frequency (RF) carriers where each RF carrier corresponds to a logical entity or object used in multi-carrier communications called a cell. A receiving radio node receives signals on serving cells, including a serving cell on a primary carrier and a serving cell on a secondary carrier, and on neighboring cells, including a neighboring cell on the primary carrier and a neighboring cell on the secondary carrier. Initially, a power delay profile is calculated for each of the serving cells and the neighboring cells. An association is determined between at least one cell on the primary carrier and at least one cell on the secondary carrier based on the calculated power delay profiles. The association is then later used in performing interference cancellation in the radio node.

    摘要: A wireless receiver utilizes a single analog oscillator to down-convert multi-carrier signals in one or more receiver front-end paths. The received signals are digitized, and the different carrier signals received at each antenna are separated in digital domain by mixing the digitized signal from each antenna with a carrier/antenna separation digital oscillator to down-convert a desired carrier signal and low-pass filtering to remove unwanted carriers. A coarse frequency correction adjusts the analog oscillator, and fine frequency corrections adjust digital oscillators mixing with the separated signals. In one embodiment, the fine frequency correction is applied to the carrier/antenna separation digital oscillators in the separation function. In another embodiment, the fine frequency correction is applied to frequency adjustment digital oscillators mixing with the separated signals. The frequency corrections may be based on reference symbols in the received signals.
