The indication report channel status information is used to instruct the MS to report the channel status to the BS, which may specifically be CQICH (Channel Quality Indicator Channel, Channel Quality Indicator Channel) information allocated to the MS, and may also be implemented by adding bits, etc., For example, a bit is added corresponding to each awakened terminal, and when the bit is set to 1, it indicates that the CQICH is enabled, and the MS can enable the CQICH allocated to it by the previous BS. In this way, the assignment information of the CQICH resource does not need to be carried in the mobile service indication information. Otherwise, when the bit position is 0, it means that the CQICH is not enabled, and the MS does not need to enable the CQICH, and sends CQI (Channel Quality Indicator, channel quality indication) information to the BS.

In addition, a report indication flag can also be added to the MOB_TRF-IND information, and the awakened MS can judge whether the received MOB_TRF-IND information carries CQICH information assigned to the MS according to the report indication flag. For example, a bit is added corresponding to each wake-up MS. When the bit position is 1, it means that the BS allocates CQICH for the wake-up MS. The MS can configure or update the CQICH according to the CQICH information in the MOB_TRF-IND information. BS Receive the CQI information sent by the MS through the CQICH. Otherwise, when the bit position is 0, it means that the BS does not allocate a CQICH to the awakened MS. At this time, the MS can use other CQICHs or not use CQICHs at all.

202. The BS receives the channel status information sent by the MS;

When the MOB_TRF-IND information sent by the BS to the MS carries CQICH information allocated to the MS, the MS configures or updates the CQICH according to the CQICH information, and the BS receives the CQI information sent by the MS through the CQICH.

In addition, when the MOB_TRF-IND information sent by the BS to the MS also carries a report indication flag, the MS will judge whether the received MOB_TRF-IND information carries the CQICH information assigned to the MS according to the report indication flag, that is, whether the BS is MS allocates CQICH.
