Abstract

The present disclosure provides a spectrum resource sharing method and an base station. The method includes: acquiring, by a first-communications standard base station, time and frequency information and power of each second-communications standard channel interfering with the first-communications standard base station; if in one transmission time interval, no frequency number in a shared spectrum is occupied by the second-communications standard channels, using, by the first-communications standard base station, the shared spectrum for uplink and downlink data channel scheduling in the one transmission time interval.

First claim

What is claimed is:

1. A spectrum resource sharing method, comprising:
acquiring, by a first-communications standard base station, frequency domain information of each second-communications standard channel interfering with the first-communications standard base station, wherein the frequency domain information comprises: frequency numbers which are obtained when the second-communications standard channels are occupied;
determining, by the first-communications standard base station according to the frequency domain information of the second-communications standard channels, whether one or more frequency numbers in a shared spectrum are occupied by the second-communications standard channels; and
when no frequency number in the shared spectrum is occupied by the second-communications standard channels, using, by the first-communications standard base station, the shared spectrum for uplink and downlink data channel scheduling in one transmission time interval.

2. The method according to claim 1 , further comprising:
when in the one transmission time interval, one or more frequency numbers in the shared spectrum are occupied by the second-communications standard channels, skipping the using, by the first-communications standard base station, the shared spectrum for the uplink and downlink data channel scheduling in the one transmission time interval.

3. The method according to claim 1 , further comprising:
when in the one transmission time interval, one or more frequency numbers in the shared spectrum are occupied by the second-communications standard channels, using, by the first-communications standard base station, the shared spectrum for the uplink and downlink data channel scheduling when the first-communications standard base station determines that a current signal quality meets a preset standard.

4. The method according to claim 3 , wherein that the first-communications standard base station determines that the current signal quality meets the preset standard comprises:
acquiring, by the first-communications standard base station, power information of each second-communications standard channel interfering with the first-communications standard base station; and
obtaining, by the first-communications standard base station, a signal to interference plus noise ratio (SINR) by using power information of the second-communications standard channels that occupy the one or more frequency numbers; and
when the SINR is greater than a first threshold, using the shared spectrum for the uplink and downlink data channel scheduling in the one transmission time interval.

5. The method according to claim 4 , further comprising:
determining, according to the SINR, an order of a modulation and coding scheme (MCS) used when the first-communications standard base station performs the uplink and downlink data channel scheduling.

6. The method according to claim 1 , further comprising:
acquiring, by the first-communications standard base station, time domain information of each second-communications standard channel interfering with the first-communications standard base station, wherein the time domain information comprises timeslot numbers and/or Time Division Multiple Access (TDMA) frame numbers which are obtained when the second-communications standard channels are occupied; and
when the first-communications standard base station determines, according to the time domain information and the frequency domain information of the second-communications standard channels, that the one or more frequency numbers are occupied by the second-communications standard channels in a TDMA frame timeslot corresponding to the one transmission time interval, skipping the using, by the first-communications standard base station, the one or more frequency numbers for the uplink and downlink data channel scheduling.

7. The method according to claim 1 , further comprising:
acquiring, by the first-communications standard base station, time domain information of the second-communications standard channels interfering with the first-communications standard base station, wherein the time domain information comprises: timeslot numbers and/or Time Division Multiple Access (TDMA) frame numbers which are obtained when the second-communications standard channels are occupied; and
when the first-communications standard base station determines, according to the time domain information and the frequency domain information of the second-communications standard channels, that the one or more frequency numbers are occupied by the second-communications standard channels in a (TDMA) frame timeslot corresponding to the one transmission time interval, using, by the first-communications standard base station, the one or more frequency numbers for the uplink and downlink data channel scheduling when the first-communications standard base station determines that a current signal quality meets a preset standard.

8. A spectrum resource sharing method, comprising:
acquiring, by a first-communications standard base station, time domain information of each second-communications standard channel interfering with the first-communications standard base station, wherein the time domain information comprises timeslot numbers and/or Time Division Multiple Access (TDMA) frame numbers which are obtained when the second-communications standard channels are occupied;
determining, by the first-communications standard base station in one transmission time interval, whether a shared spectrum is occupied by the second-communications standard channels in a TDMA frame timeslot corresponding to the one transmission time interval; and
when in the one transmission time interval, the shared spectrum is not occupied by the second-communications standard channels, using, by the first-communications standard base station, the shared spectrum for uplink and downlink data channel scheduling in the one transmission time interval.

9. The method according to claim 8 , further comprising:
acquiring, by the first-communications standard base station, frequency number information of the shared spectrum; and
when in the one transmission time interval, one or more frequency numbers in the shared spectrum are occupied by the second-communications standard channels, skipping the step of using, by the first-communications standard base station, the shared spectrum for the uplink and downlink data channel scheduling in the one transmission time interval.

10. The method according to claim 8 , further comprising:
acquiring, by the first-communications standard base station, frequency number information of the shared spectrum; and
when in the one transmission time interval, one or more frequency numbers in the shared spectrum are occupied by the second-communications standard channels, using, by the first-communications standard base station, the shared spectrum for the uplink and downlink data channel scheduling in the one transmission time interval when the first-communications standard base station determines that a current signal quality meets a preset standard.

11. The method according to claim 10 , wherein the first-communications standard base station determines that the current signal quality meets the preset standard comprises:
acquiring, by the first-communications standard base station, power information of each second-communications standard channel interfering with the first-communications standard base station;
obtaining, by the first-communications standard base station, a signal to interference plus noise ratio (SINR) by using power information of the second-communications standard channels that occupy the one or more frequency numbers; and
