AI Technical Summary

Problems solved by technology

Although multiple cells can use Soft Handover (SHO) in CELL_DCH to receive uplink transmissions from the UE, SHO is not possible in CELL_FACH
Therefore, neighboring cells cannot reduce their interference
In the past, CELL_FACH was designed for short transmission bursts and used as a temporary state, and thus, UEs in overlapping coverage areas could not generate prolonged interference

Embodiment Construction

[0042] figure 1A cellular communication network is illustrated having a first base transceiver station 300 operating a first cell marking its coverage area with 300a. Furthermore, the network comprises a second base transceiver station 301 operating a second cell of its coverage area marked with 301a. also, figure 1 A mobile transceiver 200 is shown located in a part of a network where the coverage areas 300a and 301a of a first cell and a second cell overlap. Arrow 300b indicates the data transmission of the mobile transceiver 200 to the first cell 300a. Arrow 301b indicates the interference generated by the mobile transceiver 200 in the second cell 301a. Hereinafter, an embodiment in which the mobile communication network is UMTS will be described.

[0043] exist figure 1 , a UE 200 is attached to a cell or Node B (NB) 300a and is located in the overlapping coverage area of ​​a first NB 300a and a second NB 301a. The transmission of the UE 200 will cause interference t...

Abstract

Method, apparatus and computer program for a mobile transceiver 200 and a base station transceiver 300 of a cellular mobile communication network communicating with the mobile transceiver 200 using packet switched data, the mobile communication network comprising a plurality of base station transceivers 300, 301. A base station transceiver 300, 301 operating one or more cells 300a, 301a. The mobile station is associated with a first cell 300a. Interference reduction information is received from a second cell 301a, the interference reduction information comprising an indication on a request of the second cell 301a to reduce the transmission power of the mobile transceiver 200 to reduce the interference power received at the second cell 301a. A transmission power of the mobile transceiver 200 is reduced based on the interference reduction information from the second cell 301a and based on a reduction criterion. The reduction criterion being such that the transmission power of the mobile transceiver 200 is reduced by less than requested by the interference reduction information.

Description

[0001] Embodiments of the present invention relate to mobile communications, and more particularly, to mobile communications networks using packet-switched data transmission. Background technique [0002] There is an increasing demand for higher data rates for mobile services. Meanwhile, modern mobile communication systems such as third generation systems (3G) and fourth generation systems (4G) provide enhanced technologies that support higher spectral efficiency and allow higher data rates and cell capacities. [0003] In the Universal Mobile Telecommunications System (UMTS), the radio resource management of the User Equipment (UE) is mainly implemented by the Third Generation Partnership Project (3GPP ) to implement the Radio Resource Control (RRC) protocol specified in the specification. A UE or mobile transceiver with RRC connection can transmit and receive user traffic in CELL_DCH state and CELL_FACH state. The CELL_FACH state is typically used for low and bursty traffi...
