Example Embodiment

[0024] In view of the situation that both the primary and secondary carriers support code channel configuration in designated time slots, in order to achieve a reasonable allocation of transmit power between the carriers, thereby ensuring system performance, in the embodiment of the present invention, the network-side device needs to be separately scheduled for the planned cell. The transmit power of each carrier included in each frequency band is configured because, under normal circumstances, the radio resources obtained by a cell are non-contiguous, that is, it contains several non-contiguous frequency bands, and each frequency band contains multiple carriers and is in the same frequency band. The transmission power of the carrier can be shared. Therefore, the network side device usually configures the transmission power of the carrier in the unit of frequency band. Then, when configuring the transmission power for each carrier included in any frequency band, the network side...

Abstract

The invention discloses a method and a device for configuring carrier transmitting power. The method and the device are used for rationally distributing the transmitting power among the carriers to ensure performance of the system. The method comprises the step that: a network side device configures the maximum allowable transmitting power of a single antenna and a single carrier of each carrier based on a public transmission first principle according to a comparison result between the total transmitting power of a public transmission channel and the maximum allowable transmitting power of each carrier in the frequency band in the appointed time slot; therefore, the maximum allowable transmitting power of the single antenna and the single carrier of the carrier does not need to be dynamically adjusted according to the expected power when the carrier carries different services, and then the implementation complexity is reduced and system stability is guaranteed; besides, when parts of the antennas fail, as the maximum allowable transmitting power of the single antenna and the single carrier of each carrier is configured according to the public transmission first principle, the residual antenna ability can be maximally used, the utilization rate of the radio resources can be ensured, the covering area of cells can be prevented from being reduced to a maximum extent, and the system performance can be effectively ensured.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for configuring carrier transmission power. Background technique [0002] At present, in order to improve the utilization rate of radio resources, a power pool technology is generally used in a cell to realize power sharing among carriers. For example, assuming that each cell can schedule M carriers, the public transmission channel (referred to as the public transmission channel) used to transmit public information is configured in the TS0 time slot of the main carrier. After adopting the power pool technology, the main carrier is allowed to Slot and downlink pilot time slot (DwPCH) use the total transmission power of M carriers for signal transmission, so as to increase the coverage of the public information of the cell; correspondingly, in the time slot used to transmit business data (referred to as , business time slots, such as TS2, TS3...TS6) The po...
