Problems solved by technology

[0005] The disadvantage of the existing technology is: for the long-term evolution system using carrier aggregation, since the transmit power of the user is limited, when the user transmits multiple uplink control channels at the same time, the transmission of data and pilots on each uplink control channel Power should be reduced
The reduction of power on the reference symbols will directly affect the reliability of channel estimation at the receiving end, thereby reducing the demodulation performance of control information on each uplink control channel

Abstract

The invention discloses transmission processing method and equipment of an uplink control channel. The method comprises the following steps that in a carrier aggregation long term evolution system, base station configures a plurality of uplink control channels sent by user equipment on the same physical resource block; the user equipment sends a plurality of physical uplink control channels and reference marks on the same physical resource block according to the base station configuration; and the base station receives the physical uplink control channels and the reference marks sent by the user equipment on the same physical resource block, and carries out channel estimation according to the reference marks to obtain a channel estimation result for demodulation. The result reliability ofthe channel estimation of the base station can be improved by implementing the invention, and finally, the demodulation performance of an uplink control signaling is improved. The invention is easy to implement and simultaneously is suitable for frequency division duplex and time division duplex systems.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a transmission processing method and equipment of an uplink control channel. Background technique [0002] figure 1 is a schematic diagram of a single-spectrum system, figure 2 It is a schematic diagram of a spectrum aggregation system. For a long-term evolution multi-carrier system, in order to support a wider system bandwidth than an LTE (Long Term Evolution, long-term evolution) system, such as 100MHz, one possibility is to directly allocate a spectrum with a bandwidth of 100M, such as figure 1 One possibility is to aggregate some spectrum allocated to the existing system to form a large bandwidth for the long-term evolution multi-carrier system. At this time, the uplink and downlink carriers in the system can be configured asymmetrically, that is, users may occupy N≥ 1 carrier for downlink transmission, M≥1 carrier for uplink transmission, such as figure 2 shown. When ...
