Technical field

The present invention relates to the field of satellite communication and wireless mobile communication technologies, and in particular, to a method and apparatus for reverse resource allocation.

Background technique

In the DVB-RCS2 standard protocol of the satellite communication system, the forward division uses Time Division Multiplexed (TDM) transmission, and the reverse uses Multi-Frequency Division Multiple Access (MF-TDMA) transmission. Support adaptive modulation coding, the access network side measures the reverse signal to noise ratio of the access terminal, and then selects the corresponding modulation and coding mode according to the signal to noise ratio for scheduling. When the access network side selects the modulation and coding mode through the reverse signal-to-noise ratio of the access terminal, the guaranteed bit rate and the maximum bit rate (MBR, Max Bit Rate) are ensured according to the guaranteed bit rate configured by the access terminal. ) Perform bandwidth resource allocation.

When there are multiple access terminals under the satellite communication system, and the reverse signal-to-noise ratio of the access terminal is different due to the hardware device capability of the terminal or the service area of the terminal, the reverse signal-to-noise ratio is different, and the corresponding modulation and coding mode is adopted. Therefore, the inverse spectrum efficiency of each access terminal is different. Therefore, the reverse resource allocation method described above has the following problems for the application of the system reverse spectrum resource:

Low bandwidth resource utilization problem: If the system reverse bandwidth is 1MHz, there are two equal priority access terminal services, the reverse guaranteed resource rate is large enough, the priority ratio is fair scheduling, and the reverse signal-to-noise ratio of access terminal A is 13db, select 8PSK modulation and 3/4 code rate, its spectral efficiency is 2.25, access terminal B reverse signal-to-noise ratio is 3db, select 4 times spread spectrum QPSK modulation and 3/4 code rate, its spectrum efficiency is 0.375, Then its average spectral efficiency is (2.25+0.375)/2=1.312, and the total bandwidth rate of the system is only 1.312 Mbps/s. When there are more end stations with low reverse signal-to-noise ratio (SNR), the total bandwidth rate of the system. It will be even lower, seriously affecting spectrum utilization.

The uncontrollable problem of bandwidth resource allocation: if the system has a reverse bandwidth of 1 MHz, there are two different priority access terminal services, and the reverse guaranteed resource rate is 2 Mbps/s, the priority ratio is fair scheduling, and the access terminal A has a 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, and 4 times spread spectrum QPSK modulation and 3/ are selected. 4 code rate, its spectral efficiency is 0.375, according to the priority scheduling principle, the system will first serve the high priority access terminal B, so the system spectrum efficiency is 0.375, the total system bandwidth rate is 0.375Mbps / s, because access The signal-to-noise ratio of the terminal is related to the geographical location of the device hardware and the satellite signal coverage, so there is no effective control resource allocation, resulting in unreasonable application of spectrum resources.

In summary, the satellite communication system has the characteristics of large signal coverage, diversity of coverage, scarcity of spectrum resources, etc., and there is no effective application to control the broadband reverse resources of the satellite system, resulting in low system reverse spectrum utilization and bandwidth resource utilization. Problems such as unbalanced control and poor user service quality.
