Claim 14:
15. The method of claim 12, 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 UE sends the SRSs corresponding to the N groups of SRS resources, the method further comprises:
receiving, by the UE, SRS resource indication information sent by the base station, 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 UE sends the SRSs corresponding to the N groups of SRS resources, the method further comprises:
receiving, by the UE, SRS resource indication information sent by the base station, 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 receiving, by the UE, the X groups of uplink scheduling information sent by the base station, comprises:
receiving, by the UE, Downlink Control Information (DCI) sent by the base station, and obtaining the X groups of uplink scheduling information from the DCI, and
the receiving, by the UE, the DCI sent by the base station, and obtaining the X groups of uplink scheduling information from the DCI, comprises:
determining, by the UE, a bit width of the X groups of uplink scheduling information in the DCI according to a quantity of antenna ports contained in SRS resources corresponding to the X groups of uplink scheduling information; and
decoding, by the UE, the DCI according to the bit width of the X groups of uplink scheduling information in the DCI to obtain the X groups of uplink scheduling information;
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 receiving, by the UE, the X groups of uplink scheduling information sent by the base station, comprises:
receiving, by the UE, Downlink Control Information (DCI) sent by the base station, and obtaining the X groups of uplink scheduling information from the DCI; and
the receiving, by the UE, the DCI sent by the base station, and obtaining the X groups of uplink scheduling information from the DCI, comprises:
determining, by the UE, a bit width of the X groups of uplink scheduling information in the DCI according to a quantity of antenna ports contained in SRS resources corresponding to the X groups of uplink scheduling information; and
decoding, by the UE, the DCI according to the bit width of the X groups of uplink scheduling information in the DCI to obtain the X groups of uplink scheduling information.
