4 3GPP 15 frame can be dynamically allocated between uplink and downlink directions, thus the channel capacity of these links can be different. 84 Mcps, but there exists also a “narrowband” version of TDD known as TD-SCDMA. 28 Mcps. 2. UTRAN includes three types of channel concepts. A physical channel exists in the air interface, and it is defined by a frequency and a spreading code (and also by a time slot in the TDD mode). The transport channel concept is used in the interface between layers 1 and 2.
In the closed-loop power control technique, the quality measurements are done on the other end of the connection in the base station, and the results are then sent back to the mobile’s transmitter so that it can adjust its transmission power. This method gives much better results than the openloop method, but it cannot react to quick changes in channel conditions. This technique can also be applied in the opposite sense, in which the roles of the base station and the mobile are reversed. The UTRAN FDD uses a fast closed-loop power control technique both in the uplink and downlink.
A UE communicating with its serving network can spend a large part of the connection time in a Soft Handover (SHO) state. The various HO types are discussed at a rather high level in this section. 4 for the UTRAN case of 3G. 15). The UE receives the downlink transmissions of two or more base stations. For this purpose it has to employ one of its RAKE receiver fingers for each received base station. Note that each received multipath component requires a RAKE finger of its own. Each separate link from a base station is called a soft-handover branch.
