Description

A method, processor and base station for downlink power processing

technical field

The present invention relates to the technical field of wireless communication, and in particular, to a method, a processor and a base station for downlink power processing.

Background technique

The transmit power of the base station determines the cell coverage and also affects the signal quality. For a multi-subband base station wireless system with a certain total power, that is, each base station in the wireless system is configured with multiple subbands, and the maximum power that each subband can achieve is inversely proportional to the number of subbands used in the system, When the system uses a large number of subbands, the power of a single subband decreases, which reduces the cell coverage distance and reduces the quality of service signals; on the contrary, when the number of subbands used by the system is small, the single subband power is relatively large, and the coverage distance increases. , the service signal quality is improved.

For a wireless broadband communication system that supports multi-subband services, more subbands need to be used, which reduces the transmit power of a single subband and affects the coverage distance. Considering that in the power system, the general multi-subband services are asymmetric services, that is, the uplink occupies more subbands, and the number of subbands occupied by the downlink is very small, and when the uplink is transmitting services, the subbands that are not used in the downlink are used. At present, it cannot be used for other services, so there is no need to reserve power for this sub-band.

In the existing discrete narrowband systems (such as the LTE230 system), in order to increase the user bandwidth and further improve the transmission rate, the carrier aggregation method is usually used to combine multiple discrete spectrums to form a virtual continuous spectrum, and finally realize the broadbandization of discrete narrowband resources. , providing voice, video and other broadband data services. In this system, scheduling is to ensure that the scheduler can monitor the transmission status of each channel and the channel quality changes of the wireless environment in a timely manner, and adjust the allocation of physical resources in a timely manner according to these changes. The purpose is to meet the QoS requirements of services, make full use of wireless resources, improve system throughput, and improve resource utilization efficiency.

In this discrete narrowband system, the demand for high-speed data services is growing, especially for video services. High-rate data services are mostly multi-subband Guaranteed Bit Rate (GBR) services.

The existing discrete narrowband system's processing solution for downlink transmit power is to evenly distribute the maximum transmit power to all configured subbands. When multi-subband services are performed, more subbands are required, which will make downlink single subbands. The transmit power is reduced, thereby affecting the cell coverage.

Based on the characteristics of the current multi-subband service, the number of subbands required for downlink is far less than the number of uplink subbands, so even if the downlink subbands are idle, the power in these subbands cannot be used for other subbands.
