Embodiment Construction

[0018] see image 3 with Figure 4 As shown, the dedicated physical control channel transmission method with power offset of the present invention is mainly for pilot frequency (Pilot), transport format combination indicator (TFCI), feedback information ( FBI), transmit power control (TPC) domain transmit power, before spread spectrum modulation, make each domain in the dedicated physical control channel relatively unequal offset value energy transmission, to optimize uplink dedicated physical control channel transmission comprehensive performance.

[0019] The energy of relative unequal offset values ​​between the pilot frequency field, transmission format combination indicator field, feedback information field, and transmission power control field can be based on the energy of any one of the fields, and the energy of the other fields is in the An optimal power bias value is set respectively for this reference value.

Abstract

The present invention discloses a transmission method of special physical control channel with power bias. The sending power of pilot frequency domain, transmission format combined indication domain, feedback information domain and sent power controlling domain in wideband CDMA ascending special physical control channel is biased separately before band-spreading modulation. This can optimize the comprehensive transmission performance of ascending physical control channel, match the performance of different domains, reduce the required power value of the whole link, reduce the interference to other users and raise the capacity of whole system.

Description

technical field [0001] The invention relates to a mobile communication system, in particular to a dedicated physical control channel transmission method with power offset in the uplink of the wideband code division multiple access communication system. Background technique: [0002] In the uplink dedicated channel of wideband code division multiple access, the dedicated channel is composed of two parts, which are dedicated physical data channel and dedicated physical control channel. After the dedicated physical data channel and the dedicated physical control channel are respectively spread with corresponding orthogonal variable spreading factor (0VSF) codes, they are multiplied as I and Q signals with a complex scrambling code, and then transmitted. [0003] In the 3GPP agreement, the power factor of the specified dedicated physical data channel is β d , the power factor of the dedicated physical control channel is β c . By adjusting β d and beta c value, the power off...
