Abstract
The invention provides a bandwidth resource processing method and device. The bandwidth resource processing method comprises steps of choosing a suitable LTE standard system bandwidth to match, adopting a PCI screening module and a physical scheduling regulation module to guarantee that an uplink channel and a downlink channel have smallest mapping in a frequency band or fall into the outside of a non-standard bandwidth with a zero limit according to scheduling and resource mapping characteristics of an LTE uplink channel and an LTE downlink channel and a service channel, using an emission power enhancement module to enhance the physical channel power in order to improve channel transmission and obtaining a time domain signal matched with a non-standard bandwidth to emit through an RRU filter. The bandwidth resource processing method and device solve a problem that a limited network spectrum cannot be effectively utilized when a wireless network spectrum is an LTE non-standard bandwidth, realize bandwidth compression emission of the LTE system under a non-standard bandwidth resource and highly effectively use wireless network resource.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a bandwidth resource processing method and device. Background technique [0002] The Long term evolution (LTE for short) system is the evolution of the third generation (3G for short) mobile communication system, which uses Orthogonal Frequency Division Multiplexing (OFDM for short) and multiple input multiple Output (Multiple-Input Multiple Output, referred to as MIMO) and other core technologies as the basis, to provide users with higher data transmission rate, lower transmission delay and better quality of service. In view of this, the LTE system is being extensively studied 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 in wireless communication. Currently, there are various standards supported by wireless networks, including, for example...
