Embodiment 1

[0044] The method embodiment provided in Embodiment 1 of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking running on a mobile terminal as an example, figure 1 It is a hardware structural block diagram of a mobile terminal according to a method for sending uplink information in an embodiment of the present invention. Such as figure 1 As shown, the mobile terminal 10 may include one or more ( figure 1 Only one is shown in the figure) processor 102 (processor 102 may include but not limited to processing devices such as microprocessor MCU or programmable logic device FPGA), memory 104 for storing data, and transmission device for communication function 106. Those of ordinary skill in the art can understand that, figure 1 The shown structure is only for illustration, and it does not limit the structure of the above-mentioned electronic device. For example, the mobile terminal 10 may also include figure 1...

Embodiment 2

[0063] In this embodiment, a method for sending uplink information is also provided, image 3 is a flow chart of the second method for sending uplink information according to an embodiment of the present invention, such as image 3 As shown, the method includes the following steps:

[0064] Step S302, determine the uplink antenna used by the user equipment UE to send the first uplink information and the second uplink information in the same subframe, and indicate the determined uplink antenna to the UE; or, use multiple antennas to send downlink information to the user equipment UE Sending reference information, where the reference information is used by the UE to select an uplink antenna for sending the first uplink information and the second uplink information among multiple antennas;

[0065] Wherein, the above-mentioned first uplink information includes at least one of the following: uplink sounding reference signal SRS, uplink detection signal, and the above-mentioned se...

specific Embodiment approach 1

[0078] The premise of the application of this solution is that the upper layer configures the uplink antenna rotation switch to enable, turns on the closed-loop antenna selection switch, and transmits the information to the UE. When selecting an uplink antenna, the base station judges the uplink antenna to be sent, and the UE performs the judgment of the base station.

[0079] It is assumed here that the UE has two antennas:

[0080] 1. After receiving the closed-loop antenna transmission instruction, the UE transmits the SRS in the manner stipulated in the 36.213 protocol.

[0081] 2. The base station receives the SRS information sent by the UE. The UE antennas antenna0 and antenna1 send SRS information at different times. After receiving the SRS information, the base station judges the strength of the signals sent by the two antennas within the time window T0.

[0082] Here, it is assumed that within the time window T0, the antenna0 signal is received N times and the ante...
