Description

Method and device for reverse resource allocation of wireless communication system
Technical Field
The present invention relates to the field of satellite communications and wireless mobile communications technologies, and in particular, to a method and an apparatus for allocating reverse resources in a wireless communication system.
Background
In a DVB-RCS2 standard protocol of a satellite communication system, TDM (Time Division Multiplexed) transmission is adopted in the forward direction, MF-TDMA (Multi frequency-Time Division Multiple Access) transmission is adopted in the reverse direction, adaptive modulation and coding is supported in the reverse direction, the reverse signal-to-noise ratio of an Access terminal is measured at the side of an Access network, and then a corresponding modulation and coding mode is selected for scheduling according to the signal-to-noise ratio. When the access network side selects the modulation coding mode through the reverse signal-to-noise ratio of the access terminal, bandwidth resource allocation is carried out according to the guaranteed Bit Rate guaranteed resource Rate (guaranteed Bit Rate) and the maximum Bit Rate MBR (Max Bit Rate) configured by the access terminal.
When a plurality of access terminals exist in a satellite communication system, and the reverse signal-to-noise ratios of the access terminals are different due to differences in hardware device capabilities of the terminals or service areas where the terminals are located, the corresponding modulation and coding modes are also different, so that the reverse spectrum efficiencies of the access terminals are different, and the reverse resource allocation method has the following problems in application of system reverse spectrum resources:
the problem of low utilization rate of bandwidth resources is as follows: for example, the reverse bandwidth of the system is 1MHz, there are 2 access terminals serving with the same priority, the reverse guaranteed resource rate is large enough, the priority ratio is fair scheduling, the reverse signal-to-noise ratio of the access terminal a is 13db, 8PSK modulation and 3/4 code rate are selected, the spectral efficiency is 2.25, the reverse signal-to-noise ratio of the access terminal B is 3db, 4-fold spread spectrum QPSK modulation and 3/4 code rate are selected, and the spectral efficiency is 0.375, then the average spectral efficiency is (2.25 + 0.375)/2 =1.312, that is, the total bandwidth rate of the system is only 1.312Mbps/s, when there are more end stations with low reverse signal-to-noise ratio accessing the system service, the total bandwidth rate of the system is lower, and the spectrum utilization rate is seriously affected.
The problem of uncontrollable bandwidth resource allocation: if the reverse bandwidth of the system is 1MHz, access terminals with 2 different priorities are served, the reverse guaranteed resource rates are all 2Mbps/s, the priority is proportional fair scheduling, the access terminal A has low priority, the reverse signal-to-noise ratio is 13db, 8PSK modulation and 3/4 code rate are selected, the spectrum efficiency is 2.25, the access terminal B has high priority, the reverse signal-to-noise ratio is 3db, 4-time spread spectrum QPSK modulation and 3/4 code rate are selected, the spectrum efficiency is 0.375, and according to the priority scheduling principle, the system can serve the access terminal B with high priority first, so the spectrum efficiency of the system is 0.375, namely the total bandwidth rate of the system is 0.375Mbps, and because the signal-to-noise ratio of the access terminal is related to the geographical positions covered by equipment hardware and the satellite signal, no effective resource control is allocated, and the spectrum resource application is unreasonable.
In summary, the satellite communication system has the characteristics of large signal coverage, coverage diversity, scarce spectrum resources and the like, and has no application of effectively controlling the broadband reverse resources of the satellite system, so that the problems of low utilization rate of the reverse spectrum of the system, unbalanced and uncontrollable utilization of the bandwidth resources, poor user service quality and the like are caused.

Specifically, a method for allocating reverse resources of a wireless communication system according to a first embodiment of the present invention is based on an access network, and the method provided by the present invention is also applicable to allocating reverse resources of a satellite communication system, and specifically includes:
s1: determining a signal-to-noise ratio interval to which the signal-to-noise ratio of the target channel belongs in a reverse communication signal-to-noise ratio range; the reverse communication signal-to-noise ratio range comprises at least two signal-to-noise ratio intervals, and each signal-to-noise ratio interval corresponds to different signal-to-noise ratios.

However, the second weighting factor is not limited in this embodiment, and only meets the requirements of the present invention, which falls into the protection scope of the present invention. In the scheme, corresponding reverse resources are allocated to the target channel by the guaranteed resource rate efficiency weight of each access terminal in the signal-to-noise ratio interval and then according to the guaranteed resource rate efficiency weight of each access terminal in the signal-to-noise ratio interval. In addition, the configuration of the guaranteed resource rate efficiency weight of each access terminal in the signal-to-noise ratio interval is configured according to the size of the signal-to-noise ratio interval and/or the minimum guaranteed resource ratio of the size of each signal-to-noise ratio interval.

In this embodiment, how to allocate the corresponding reverse resource to the target channel by using the guaranteed resource rate efficiency weight of each access terminal in the snr interval is not limited, and it is only necessary that the requirement of the present invention is met, which belongs to the protection scope of the present invention.
