Claim 6:
7. The method of claim 4, wherein one or a combination of following schemes is performed:
scheme I: each group of uplink scheduling information comprises: a Transmit Precoding Metrix Indicator (TPMI), of an SRS resource corresponding to the each group of uplink scheduling information, and different groups of uplink scheduling information indicate an equal number of transmission streams;
scheme II: each group of uplink scheduling information comprises: a transmit layer indicator, of an SRS resource corresponding to the each group of uplink scheduling information, and different groups of uplink scheduling information indicate an equal number of transmission streams;
scheme III: each group of uplink scheduling information comprises: a Transmit Precoding Metrix Indicator (TPMI), of an SRS resource corresponding to the each group of uplink scheduling information, and
after the base station receives the SRSs sent by the UE, the method further comprises:
sending, by the base station, SRS resource indication information to the UE, wherein the SRS resource indication information indicates one or more SRS resources corresponding to each group of uplink scheduling information;
scheme IV: each group of uplink scheduling information comprises: a transmit layer indicator, of an SRS resource corresponding to the each group of uplink scheduling information, and
after the base station receives the SRSs sent by the UE, the method further comprises:
sending, by the base station, SRS resource indication information to the UE, wherein the SRS resource indication information indicates one or more SRS resources corresponding to each group of uplink scheduling information;
scheme V: each group of uplink scheduling information comprises: a Transmit Precoding Metrix Indicator (TPMI), of an SRS resource corresponding to the each group of uplink scheduling information, and
the sending, by the base station, the X groups of uplink scheduling information to the UE, comprises:
determining, by the base station, a bit width of the X groups of uplink scheduling information in Downlink Control Information (DCI), according to a quantity of antenna ports contained in SRS resources corresponding to the X groups of uplink scheduling information,
generating, by the base station, the DCI, and
sending, by the base station, the X groups of uplink scheduling information to the UE through the DCI,
scheme VI: each group of uplink scheduling information comprises: a transmit layer indicator, of an SRS resource corresponding to the each group of uplink scheduling information, and
the sending, by the base station, the X groups of uplink scheduling information to the UE, comprises:
determining, by the base station, a bit width of the X groups of uplink scheduling information in Downlink Control Information (DCI), according to a quantity of antenna ports contained in SRS resources corresponding to the X groups of uplink scheduling information,
generating, by the base station, the DCI, and
sending, by the base station, the X groups of uplink scheduling information to the UE through the DCI.
