TTI CHANNEL ARRANGEMENT AND UE TO CHANNEL ASSIGNMENT

摘要

Method and apparatus for operating a high speed uplink base station, comprising at least one downlink control channel (E-AGCH) on which mobile user entities are scheduled to receive absolute grants, the downlink control channel being arranged into transmission intervals corresponding to a first interval (P1) or a second interval (P2), the possible start of a first transmission interval (P1) being defined by a period corresponding to an integer number times the duration of the first transmission interval from a predefined (t1) frame on an additional control channel (P-CCPCH), the possible start of a second transmission interval (P2) being defined by a period corresponding to an integer number times the duration of the second transmission interval (P2) from the predefined (t1 ) frame on an additional control channel (P-CCPCH), wherein the base station is adapted to communicate with first type user entities (UE1 ) exclusively being able to communicate in the first transmission intervals (P1) and with second type user entities (UE2) being able to communicate in the second transmission intervals (P2). The steps of calculating the load on each configured channel (iii); assigning (vi) or re-assigning user entities to respective arranged downlink control channels (vi), while scheduling (x) traffic for assigned user entities on at least a given channel having transmission intervals of the first interval (P1 ) and / or the second interval (P2), whereby the proportion of first intervals (P1) to second interval (P2) varies dynamically, are carried out.
