    摘要: A communication unit and a method for communicating at least one signal over a channel of a first channel type and at least one signal over a channel of a second channel type, which is different from the first channel type. The apparatus comprises a timer adapted to schedule a predetermined time period, during which interference due to simultaneous communication of signals over the channel of the first channel type and the channel of the second channel type is anticipated. Also, the apparatus comprises a processing unit adapted to apply, during the predetermined time period, an interference counteracting process for counteracting interference between any signal communicated over the channel of the first channel type and any signal communicated over the channel of the second channel type. The interference counteracting process comprises changing, during the predetermined time period, from a first to a second format for representing information transmitted over the channel of the first channel type, the second format being more robust than the first format.

    摘要: A method in a network node in control of a cell in a cellular telecommunication network for reducing intra-cell interference between user equipments (UE) residing in said cell and performing random access (RA). The method comprises the steps of arranging groups of preamble sequences where the sequences within each group are orthogonal to each other, assigning one such group to the cell, from which group the UEs performing RA randomly selects a preamble, and assigning one or more additional group(s) of preamble sequences to said cell if the RACH or traffic load exceeds a certain threshold. The invention further relates to a radio network node in a cellular telecommunication system, capable of carrying out said method.
