Abstract

The present invention provides a method and device for processing bandwidth resources, wherein the method includes: selecting an appropriate LTE standard system bandwidth to match it, and then according to the characteristics of scheduling and resource mapping of LTE uplink and downlink control channels and traffic channels, using The PCI screening module and the physical channel scheduling adjustment module ensure that the mapping of the uplink and downlink channels in the frequency band falls outside the non-standard bandwidth to a minimum or zero limit; use the transmit power enhancement module to enhance the power of the physical channel to improve channel transmission performance; finally filter through RRU The device obtains the time-domain signal matching the non-standard bandwidth for transmission, which solves the problem that the limited network spectrum cannot be efficiently used when the wireless network spectrum is the non-standard bandwidth of LTE, and realizes the bandwidth compression of the LTE system under non-standard bandwidth resources Efficient use of wireless network resources.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method and device for processing bandwidth resources. Background technique [0002] Long term evolution (LTE for short) system is the evolution of the third generation (3G for short) mobile communication system. Based on core technologies such as Multiple-Input Multiple Output (MIMO), it provides users with higher data transmission rates, lower transmission delays and better service quality. In view of this, the LTE system is being widely researched and applied to today's commercial networks. [0003] With the development of wireless communication technology, efficient utilization of limited network spectrum has become a problem of wireless communication. At present, there are many formats supported in wireless networks, including, for example, Global System for Mobile Communication (GSM for short), wideband Code Division Multiple Access (CDMA for short), Universal ...
