Abstract

The invention relates to a base station and a multi- access method. The method comprises the following steps of: determining the number of time resources and frequency resources required by user equipment; on the basis of the determined number of the time resources and the frequency resources and a basic spectrum-spreading code word configured to the user equipment, constructing a spectrum-spreading codebook of the user equipment; performing time-domain and frequency-domain spreading of data of the user equipment by adopting the constructed spectrum-spreading codebook, so that a corresponding time-domain and frequency-domain sequence is obtained; and respectively mapping elements in the obtained time-domain and frequency-domain sequence onto the corresponding time and frequency resources. By means of the scheme, the multi-access flexibility can be improved; and different service transmission requirements of the user equipment can be satisfied.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a base station and a multiple access method. Background technique [0002] The multiple access technology divides the signal dimension into different channels and distributes them to users. Generally, the dimension of the signal space is divided into orthogonal or non-orthogonal user channels according to the time axis, frequency axis or codeword axis. When multiple access is established with different divisions of the carrier frequency of the transmission signal, it is called Frequency Division Multiple Address (FDMA); when multiple access is established with different divisions of the transmission signal existence time, It is called Time Division Multiple Address (TDMA); when the multiple access is established by different divisions of transmission signal patterns, it is called Code Division Multiple Address (CDMA). [0003] Massive user equipment access and high data trans...
