    摘要: A method of operating a user equipment communicating with a base station of a radio access network may include selecting a multiple-input-multiple-output, MIMO, rank and a MIMO precoding entity from a codebook of MIMO precoding entities for a downlink communication from the base station to the user equipment. A modulation/coding scheme to be mapped to first and second MIMO layers of the downlink communication may be selected using the MIMO precoding entity. Channel quality information may be communicated identifying the MIMO precoding entity and the modulation/coding scheme from the user equipment to the base station. Related user equipment nodes are also discussed.

    摘要: When a UE (12) is configured with MF-HSDPA and HARQ-ACK information associated with cells (14, 16) (characterized by potentially different downlink timing) is jointly encoded, only part of the existing Rel-9 HARQ-ACK codebook is reused. In one embodiment, only the codebook conflict arising from reuse of encodings is resolved. This is achieved by introducing a new codeword for at least one of the HARQ-ACK code words that are used multiple times in the existing Rel-9 codebook. In another embodiment, all codewords in the Rel-9 HARQ-ACK codebook having a Hamming distance smaller than a predetermined value (but not all codewords) are replaced. In yet another embodiment, all codewords in the Rel-9 HARQ-ACK codebook having a Hamming distance smaller than a predetermined value (but not all codewords) that would cause ambiguity at the NodeB receiver (i.e. where the interpretation of the HARQ-ACK information for one cell (14) depends on the number of streams transmitted at the other cell (16)) are replaced.

    摘要: Methods and devices are provided whereby a cellular radio network, in particular a node in the network is configured to dynamically transmit data to UE from different cells while considering information that is not known to a central node, such as an RNC. This can in accordance with some embodiments be accomplished by decoupling the procedure of handling a set of cells form which simultaneous transmission of data to a UE can take place.

    摘要: An uplink power control that is applied to a user equipment (300) when in communication with a serving radio base station (10) and at least one other radio base station (20) involves generating a quality representation of an uplink control channel (12) from the user equipment (300) to the serving radio base station (10). The quality representation is compared to a threshold value and this comparison defines a selective processing of transmit power control commands received by the user equipment (300) from the serving and/or non-serving radio base stations (10, 20).

    摘要: A power control applied to a radio network controller (40) when a user equipment (300) is in communication with a serving radio base station (10) and at least one other radio base station (20) involves the radio network controller (40) providing a quality representation of an uplink control channel (12) from the user equipment (300) to the serving radio base station (10). The radio network controller (40) generates an updated power quality target for a reference control channel based on the quality representation and transmits the updated power quality target to at least one of the serving radio base station (10) and the at least one other radio base station (20). Alternatively, the radio network controller (40) generates an updated power offset for the uplink control channel (12) relative a reference control channel based on the quality representation and transmits the updated power offset to the user equipment (300).
