Based on the method for sending signal provided by Fig. 3, Fig. 4 or Fig. 5, the application provides a kind of method for sending signal, SRS in this method can be specially reference signal of the Fig. 3 into Fig. 5, and time slot (slot) can be specially first of Fig. 3 into Fig. 5 Time quantum, the second time quantum or third time quantum, specific as follows:

Following scene is set, as is seen in fig. 6 or fig. 7, UE is periodically sent in slot#1, slot#6 and slot#11 SRS, and the transmission of SRS is using accumulation closed power algorithm.If UE receives to move in slot6 has dynamic dispatching in slot#6 PUSCH transmission, then in time slot #6 can simultaneous transmission PUSCH and SRS, and SRS can occupy in a slot it is last it is N number of just Frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol is handed over, for example N can be 1,2 Or 4.It is illustrated in two kinds of situation below:

The first situation, UE are configured the transmission power parameter association of SRS and PUSCH.In the embodiment of the present application, just Often accumulation closed loop process flow in, slot#6 send SRS power, need slot#1 send SRS power on the basis of into Row is cumulative, and slot#11 sends the power of SRS, needs to add up on the basis of slot#6.

Since in this application scene, SRS is configured as the transmission power parameter association with PUSCH, therefore, in slot#6 In, UE can use the transmission power parameter of PUSCH, send the transmission power parameter of power in slot#6 as SRS.Therefore, Slot#11 is obviously no longer desirable for adding up on the basis of slot#6 sends power.In the embodiment of the present application, provide with Under type determines the power that SRS is sent in slot#11:

The cumulative power on the basis of SRS transmitted in slot#11 transmits SRS in slot#1；

Slot#11 independently calculate transmission SRS closed power, such as in slot#11 resetting accumulation closed loop function power or With

Absolute power adjustment calculates.

In the embodiment of the present application, the specific employing mode 1 of UE) or mode 2) calculate slot#11 in transmit SRS power can By signal deployment, for example, can be configured by high-rise or physical layer signaling, high-level signaling can be wireless heterogeneous networks (radio resource control, RRC) signaling or media access control (media access control, MAC), physics Layer signaling can be Downlink Control Information (down control information, DCI) signaling.

Second situation, UE are configured as SRS and are not associated with PUSCH transmission power parameter.

In this application, it in order to avoid the jump of the power in a slot, therefore needs to keep PUSCH in slot#6 It is consistent with the transmission power of SRS.In one example, can in slot#6, with the transmission power of PUSCH, transmit PUSCH and SRS, alternatively, PUSCH and SRS can also be transmitted, alternatively, can also be in the transimission power and SRS of PUSCH with the transmission power of SRS Transimission power in, select the transmission power for meeting condition (for example transimission power is larger or smaller), carry out common transport PUSCH And SRS, alternatively, can also the transmission power of transmission power and SRS to PUSCH carry out comprehensive (for example averaging), and will integrate Transmission power of the transmission power as PUSCH and SRS afterwards.

At this point, sending the power of SRS in Slot#11, can determine in the following way:

The SRS transmitted in slot#11 transmits cumulative power on the transmission power level of SRS in slot#1；

Slot#11 independently calculates the transmission power of transmission SRS, for example closed power is reset in slot#11

Or absolute power adjustment calculates.

3) slot#11 can still be accumulated on the basis of the closed power of slot#6, but can add offset value, as A kind of possibility, offset value can be carried by the dispatch DCI of PUSCH.

It should be noted that in the embodiment of the present application, and the sequencing that unlimited step S1001 is executed to step 1003, For example, step S1002 can be executed before step S1001.

Therefore in the embodiment of the present application, the adjusted value equally reported without the first equipment instruction reference signal, section Save signaling overheads.

Based on the method for sending signal provided by Fig. 9 or Figure 10, the application provides a kind of method for sending signal, the party SRS in method can be specially the reference signal in Fig. 9 or Figure 10, when time slot (slot) can be specially first in Fig. 9 or Figure 10 Between unit or the second time quantum, this method is mainly used for the processing to semi-static SRS, specific as follows:

Base station can send active information to UE, and to activate the transmission of SRS, and UE is after receiving the active information, then Start to transmit SRS.In the embodiment of the present application, can reporting by the DCI semi-static SRS of signaling dynamic activation, height can also be passed through Layer signaling, such as RRC or MAC signaling activate reporting for semi-static SRS.

The first situation: if activating reporting for semi-static SRS by DCI:

1) as shown in figure 11, TPC command, the TPC command can be carried in the DCI signaling for activating semi-static SRS to report It is used to indicate the power adjustment of all SRS during this activation, i.e., the SRS sent every time can be added on the basis of previous Accumulate the power adjustment of TPC instruction.In the embodiment of the present application, the semi-static SRS of the activation reports the DCI signaling can be specially Trigger the activation (Trigger SP-SRS Activation) of semi-static SRS, it should be noted that in the embodiment of the present application, For semi-static SRS, if reporting for SRS need to be terminated, also base station is needed to be indicated, in the embodiment of the present application, still may be used Referring to 11, it can be described as triggering deactivation (the Trigger SP-SRS of semi-static SRS for terminating the signaling that semi-static SRS is reported deactivation)

2) as shown in figure 12, equally TPC command, the TPC can be carried in the DCI signaling for activating semi-static SRS to report Order is used to indicate one group of TPC value, the adjusted value of the SP-SRS of corresponding different slot transmission.As shown in figure 12；It is corresponding at this time Scene can be, and according to the tree-shaped frequency hopping in LTE in NR, can be taken according to the bandwidth of SRS transmission and frequency domain position to determine The value of one group of accumulation TPC of band, to adjust closed power.

It should be noted that in aforesaid way 1) and mode 2) in be not necessarily to additional instruction information, be used to indicate adjustment Value saves signaling overheads.Simultaneous system 2) it can flexibly indicate the power adjustment of SRS.

Second situation: if being triggered by high-level signaling (for example, MAC-CE or RRC):

1) if SRS power is configured as the transmission power parameter association with PUSCH, and has PUSCH biography in same slot It is defeated, then share the transmission power parameter and close-loop power control of PUSCH.

2) if SRS power is not associated with or in same slot without PUSCH transmission with PUSCH transmission power parameter, in advance Definition default adjusted value, such as predefined adjusted value is 0, i.e., close-loop power control is h (i)=h (i-1), is directly multiplexed upper one The closed power of secondary SRS transmission, the i represent the timeslot number of transmission SRS, and the i is the integer for being less than or equal to N greater than zero, institute It states N to represent during semi-static SRS activation, transmits the quantity of SRS in total.
