In Table 1, Octet represents an octet; Short SSN is a short start sequence number, and the start sequence number (SSN, Starting Sequence Number); BOW (Beginning of Window) is the window start point; TFI (Temporary Flow Identity) is Temporary flow ID.

The SSN carries the measured downlink RLC/MAC data block number (which can be measured by the receiving end (MS side) when receiving the data block), the TFI indicates the temporary block flow (TBF, Temporary Block Flow) for indexing, and the MR is the measurement report. Including MeanBep (Mean Bit Error Probability) and CvBep (Covariance Bit Error Probability), in addition, the measurement report may also include a modulation method (MF, Module Fashion), where MeanBep may be Add 5 Bits in the PAN field to indicate that CvBep can add 3 Bits in the PAN field. To show that the MF can be represented by adding 3 Bits in the PAN field. It should be noted that adding Bit in the PAN domain as described here can be implemented by using the original idle bit in the PAN domain, for example, using 5 Bits in the original idle bit to represent MeanBep, and using 3 of the original idle bits. Bits are used to represent CvBep, and 3 bits in the original free bits are used to represent the MF. Of course, in addition, it can be implemented in other ways.

Table 2 shows still another method for measuring reports according to an embodiment of the present invention; the measurement report shown in Table 2 can also be inserted into the PAN domain in the uplink RLC/MAC data block for transmission.

To show that the MF can be represented by adding 3 Bits in the PAN field. It should be noted that adding a bit in the PAN domain as described herein can be implemented by using the original idle bit in the PAN domain, for example, using six Bits in the original idle bit to represent the C-Value, of course, In addition, it can also be realized by other means.

It should be noted that, in the measurement reports shown in Tables 1 and 2 above, each PAN domain report can carry MeanBep and CvBep, and the method in Table 2 can also carry C-Value, which is reported relative to the current measurement report.
