example 1
[0114] In this example, the position information of the transmission opportunity in the reference signal transmission period (that is, the DRS transmission period) is: the offset of the start subframe of the reference signal relative to the start subframe of the reference signal transmission period, Or, the offset of the start subframe of the reference signal relative to the start subframe of the previous reference signal. That is to say, in this example, the location information of the transmission opportunity within the reference signal transmission period is determined by the offset of the start subframe of the reference signal relative to the start subframe of the reference signal transmission period, or, The offset of the start subframe of the reference signal relative to the start subframe of the previous reference signal is represented.
[0115] Assuming that the DRS transmission period is represented by dmtc-Peroid, the offset (offset) of the DRS transmission period is...
example 2
[0128] In this example, the position information of the transmission opportunity in the reference signal transmission period (that is, the DRS transmission period) is: a bitmap corresponding to all subframes in the reference signal transmission period, where the reference signal is indicated in the bitmap The location of the start subframe of . That is to say, in this example, the position information of the transmission opportunity in the reference signal sending period is represented by bitmaps corresponding to all subframes in the reference signal sending period.
[0129] For example, it is assumed that the DRS transmission period is 40ms, including 40 subframes of 1ms. In this embodiment, the eNB notifies the terminal of the DRS transmission opportunity (that is, the dmtc-Offset subset in Example 1) in the form of a bitmap (Bitmap) template (pattern), wherein the value of a certain bit is 1 (bit=1), Indicates that the position of the subframe corresponding to this bit is ...
example 3
[0134] In this example, the reference signal sending cycle further includes multiple non-overlapping sub-periods, and these sub-periods form a reference signal sending cycle. For convenience, each sub-period can have the same length. In this example, the transmission configuration information of the reference signal sent by the eNB to the UE also includes the duration of the sub-period. In the transmission configuration information, the position information of the transmission opportunity within the reference signal transmission period (ie, the DRS transmission period) is specifically: the offset of the starting subframe of the reference signal relative to the starting subframe of the corresponding subperiod . That is to say, in this example, the position information of the transmission opportunity within the reference signal sending period is represented by an offset of the starting subframe of the reference signal relative to the starting subframe of the corresponding subpe...
