Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, an embodiment of the present invention further provides a method for sending an uplink signal, where the method is applied to a terminal, and the method includes:
and step 12, sending an uplink signal at the sending position according to the uplink sending power.
In the embodiment, the uplink transmission power is determined according to the time interval between the transmission position of the uplink signal in one uplink and downlink period and the reference point; and sending an uplink signal at the sending position according to the uplink sending power. Therefore, the terminal is ensured to be at a position close to the reference point, namely a position possibly interfered strongly, and a signal is sent by using larger power or power adjustment is carried out by using a more aggressive scheme so as to resist interference; at a position far away from a reference point, namely a position possibly less disturbed, a signal is sent with a smaller power or a more conservative scheme is used for power adjustment to reduce the influence on the adjacent region, wherein the reference point can be an uplink and downlink time guard interval GP.
In an embodiment of the present invention, the step 11 may include:
step 111, determining at least one preset interval and at least one preset power value;
specifically, receiving indication information sent by a network device; and obtaining the preset interval from the indication information. The indication information includes: radio Resource Control (RRC) indication information or downlink control information DCI. For example, for a connected terminal, RRC) indication information may be UE-specific RRC indication information.
Obtaining at least one preset power value through system information or through Radio Resource Control (RRC) signaling; or
The method comprises the steps of obtaining at least one preset power value and at least one preset power offset through system information or Radio Resource Control (RRC) signaling, determining the preset power value according to the at least one preset power value and the at least one preset power offset, and obtaining the second power value according to the first power value and the preset power offset. The offset may be positive or negative.
For a PUSCH (physical uplink shared channel), multiple sets of expected received power or multiple sets of preset power step sizes may be configured through RRC, and which set of preset power value should be used by a currently scheduled PUSCH may be dynamically indicated through DCI.
Step 112, if a first interval between a transmission position of the uplink signal in an uplink and downlink period and the reference point is smaller than a first preset interval in the at least one preset interval, determining uplink transmission power according to a first power value in the at least one preset power value;
step 113, if a first interval between a transmission position of the uplink signal in an uplink and downlink period and the reference point is greater than or equal to a first preset interval in the at least one preset interval, determining uplink transmission power according to a second power value in the at least one preset power value; the second power value is less than the first power value.
For example:
the first mode is as follows: configuring two sets of PRACH (physical random access) expected receiving power (namely the preset power value) and a symbol indication, indicating RO (RO closer to GP and RO being a random access opportunity) on a symbol within a certain range (namely a preset interval) away from GP through system message configuration, and using a higher preset power value (namely a first power value); the farther RO uses a preset power value (i.e., a second power value) with lower power;
of course, it may be further possible to further reduce the preset interval to obtain a smaller preset interval if the first power still generates interference, for example, the preset interval is 4 slot symbols, and the smaller preset interval is 2 slot symbols, so that when the number of symbols at the sending position away from the GP is less than 2, a larger sending power may be used to send the uplink signal, for example, a third power larger than the first power. And when the number of symbols of the distance GP between the transmitting position and the transmitting position is greater than 2 and less than 4, transmitting the uplink signal by using slightly larger transmission power, for example, fourth power which is greater than the first power but less than the third power.
The transmission positions other than the transmission position distance GP having a symbol number greater than 4 are adjusted in the same manner as described above.
The second mode is as follows: configuring multiple sets of Power Ramping steps (preset Power Step) by the system message, indicating by a symbol, and performing Power adjustment by using a larger Step on an RACH transmission opportunity close to GP by the terminal; the Power adjustment is performed with a smaller Power Ramping Step on RACH transmission opportunities farther away from the GP.
Of course, the preset power value may also be determined according to a first power value of at least one preset power value and one offset of the at least one preset power offset, where the second power value is obtained by adding or subtracting the first power value and the preset power offset.
In the above embodiment, determining the uplink transmission power according to the transmission position of the uplink signal in one uplink and downlink period includes:
receiving transmission time indication information;
and when the sending times of the random access request message with the network equipment exceed the transmission times indicated by the transmission time indication information, determining the uplink sending power according to the sending positions of the uplink signals in an uplink and downlink period.
When the concrete implementation is realized, the method can comprise the following steps:
acquiring at least one preset power step length through system information or through Radio Resource Control (RRC) signaling;
determining at least one preset interval and at least one preset power value;
if a first interval between a sending position of the uplink random access transmission opportunity in an uplink and downlink period and a first reference point is smaller than a first preset interval in the at least one preset interval, determining uplink sending power according to a first power step in the at least one preset power step;
if a first interval between a sending position of the uplink random access transmission opportunity in an uplink and downlink period and a first reference point is greater than or equal to a first preset interval in the at least one preset interval, determining uplink sending power according to a second power step in the at least one preset power step;
the second power step is smaller than the first power step.
Here, determining the uplink transmission power according to the preset power step may specifically include: and adding the current transmitting power of the terminal with the preset power step length to obtain the uplink transmitting power.
Specifically, the system message configures one transmission number. After the Msg1 (random access request message) is indicated to be sent for a number of times exceeding the number of times, Power adjustment can be performed on the RACH transmission opportunity closer to the GP by using a larger Power Ramping step; and the RACH transmission opportunity far away from GP uses smaller Power Ramping Step to adjust Power.

if a first interval between a sending position of an uplink signal in an uplink and downlink period and a reference point is greater than or equal to a first preset interval in the at least one preset interval, determining uplink sending power according to a second power value in the at least one preset power value;
