Description

Control method, terminal device and network device

technical field

The present invention relates to the field of communication technologies, and in particular, to a control method, a terminal device and a network device.

Background technique

The 5th ^Generation (5G) mobile communication system supports mobile enhanced broadband, low latency, high reliability, and large-scale machine communication connection services. In order to meet the requirements of different services for performance indicators such as throughput, delay, and reliability, higher requirements are placed on the implementation of network devices such as base stations, and terminal devices such as user equipment (User Equipment, UE).

In a New Radio (NR) system, the uplink channels include: a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), and a physical random access channel (Physical random access channel, PRACH); the uplink reference signal includes: a demodulation reference signal (Demodulation reference signal, DMRS) and a sounding reference signal (Sounding reference signal, SRS).

In the NR system, for the frequency band below 6 GHz, the transition time of the UE needs 10us; for the frequency band higher than 24 GHz, the transition time of the UE needs 5us. The transition time of the UE is the power ramp up or power down time.

At present, when the transmission power of the SRS symbols continuously sent by the UE changes, the port changes, or the frequency hopping, the transition time of the UE needs to be considered. Similarly, when the power of other continuously transmitted uplink channels or uplink reference signals changes or frequency hops, the transition time of the UE also needs to be considered. However, in the existing NR mobile communication system, when at least one of PUSCH, PUCCH, PRACH and SRS is continuously transmitted (including the same channel and different channels) and the power is adjusted and transmitted, the transition time of the UE (power ramp-up or fall time) is not considered. This may cause severe inter-symbol interference or signal distortion, which in turn may result in reduced uplink reference signal or channel reception performance, and reduced uplink or downlink channel transmission rates.

Detailed ways

In order to illustrate the technical solutions of the embodiments of the present invention more clearly, the following briefly introduces the accompanying drawings that need to be used in the embodiments of the present invention. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can also be obtained from these drawings without any creative effort.

Referring to FIG. 1, an embodiment of the present invention provides a control method, which is applied to a terminal device and includes the following steps:

Step 101: Control the N uplink transmissions transmitted within one transmission time interval.

In this embodiment of the present invention, the control in step 101 may reduce inter-symbol interference or signal distortion during uplink transmission, and may include at least power control or transmission time control. Specifically, the control in step 101 may be: controlling the transmit power of the N uplink transmissions, so that the absolute value of the power difference of each two consecutive uplink transmissions within the one transmission time interval is smaller than the first A preset threshold value, or the transmission time of the N uplink transmissions is controlled so that the absolute value of the power difference of the continuous transmissions within the one transmission time interval is greater than the second preset threshold value of uplink transmissions. reserved guard interval. The N is a positive integer greater than or equal to 2.

It can be understood that, for those skilled in the art, the first preset threshold value and the second preset threshold value may be preset according to actual conditions. During specific implementation, according to the first preset threshold value, the power of uplink transmissions for continuous transmission within the transmission time interval may be the same or substantially the same, and the power of uplink transmissions for continuous transmission between transmission time intervals may be the same or different. . According to the second preset threshold value, a certain time guard interval may exist between uplink transmissions with a larger absolute value of the power difference of the continuous transmission within the transmission time interval.

It should be noted that the unit of the one transmission time interval may be a symbol, a time slot or a subframe, and further the one transmission time interval may include at least one symbol, at least one time slot or at least one subframe.

In this embodiment of the present invention, the N uplink transmissions may include: uplink channels and/or uplink reference signals.

For example, in N uplink transmissions, the combined transmission method of the uplink channel and the uplink reference signal can be referred to as shown in Table 1 below:

Table 1

It can be seen from Table 1 that the N uplink transmissions may include uplink channels of the same type, uplink channels of the same type and uplink reference signals of different types, uplink channels of the same type and uplink reference signals of the same type, uplink reference signals of the same type , uplink reference signals of the same type and uplink channels of different types, uplink reference signals of the same type and uplink channels of the same type, or uplink reference signals of different types and uplink channels of different types. It can be understood that the same type of uplink channels may include at least two PUSCHs, at least two PUCCHs and/or PRACHs, and the same type of uplink reference signals may include at least two SRSs.

Preferably, in specific implementation, the N uplink transmissions include uplink channels of the same type and/or uplink reference signals of the same type, so that the absolute value of the power difference of uplink transmissions of the same type that are continuously transmitted within the transmission time interval is less than the first preset threshold value.

In the control method according to the embodiment of the present invention, by controlling N uplink transmissions transmitted in a transmission time interval, the absolute value of the power difference of every two consecutive uplink transmissions in the transmission time interval can be made smaller, Avoid power adjustment between uplink transmissions of continuous transmission, or reserve a guard interval between uplink transmissions with a larger absolute value of the power difference of continuous transmission within the transmission time interval, thereby reducing the number of terminal equipment in the uplink transmission process. The effect of transition time reduces inter-symbol interference or signal distortion.

In the embodiment of the present invention, optionally, the uplink transmission of the continuous transmission with reserved guard interval may be carried on a carrier with a preset subcarrier interval. Optionally, the guard interval may include at least one symbol.

For example, the preset subcarrier spacing can be 60KHz subcarrier spacing below 6GHz frequency band, or 120KHz subcarrier spacing above 6GHz frequency band; or the preset subcarrier spacing can be 30KHz, 60KHz subcarrier spacing below 6GHz frequency band spacing, or 60KHz, 120KHz subcarrier spacing above 6GHz.

In the embodiment of the present invention, when the terminal device controls the uplink transmission within a certain transmission time interval, the control may be performed based on an indication from the network side, or may be controlled based on some of its own considerations. Specifically, step 101 may include:

Receive uplink power control parameter configuration information from the network device;

According to the uplink power control parameter configuration information, power control is performed on some or all of the N uplink transmissions, so that the power difference of each two consecutive uplink transmissions within the one transmission time interval is equal to The absolute value is smaller than the first preset threshold value.

It should be noted that the configuration information of uplink power control parameters sent by the network side may be one or more. When there are at least two uplink power control parameter configuration information, different uplink power control parameter configuration information may be applied to serving cells or partial bandwidths configured with different subcarrier intervals. Optionally, the uplink power control parameter configuration information may include target received power, path loss compensation factor, path loss calculation reference signal, closed-loop power adjustment process identifier, sounding reference signal resource indication (Sounding Reference Signal Resource Indication, SRI), and transmission power control (Transmit Power Control, TPC) change information of at least one of them.

In order to ensure that the uplink transmission of the terminal device within a transmission time interval adopts the same power control related parameters, the network side can configure the same power control related parameters.

In this embodiment of the present invention, optionally, the effective time of the uplink power control parameter configuration information sent by the network side may be the start time of the corresponding transmission time interval, so as to ensure timely control of the power of uplink transmission, so that the transmission time interval The absolute value of the power difference of every two consecutive uplink transmissions within the range is less than the preset threshold value.

In this embodiment of the present invention, the uplink power control parameter configuration information sent by the network side may be applied to carriers with one subcarrier interval, or may be applied to carriers with different subcarrier intervals. When applied to one subcarrier interval, the effective time of the uplink power control parameter configuration information can be directly determined according to the subcarrier interval, and when applied to different subcarrier intervals, the effective time of the uplink power control parameter configuration information can be determined according to any subcarrier interval of the different subcarrier intervals. The carrier interval determines the effective time of the uplink power control parameter configuration information. Specifically, the receiving uplink power control parameter configuration information sent by the network side may include:

Receive first uplink power control parameter configuration information on the first carrier, where the first uplink power control parameter configuration information corresponds to the first uplink transmission carried by the second carrier, and the subcarrier spacing of the first carrier is the same as that of the first uplink transmission. The subcarrier intervals of the second carrier are different, and the N uplink transmissions include the first uplink transmission.

Correspondingly, performing power control on some or all of the N uplink transmissions according to the uplink power control parameter configuration information may include:

The transmission power of the first uplink transmission is adjusted at the effective time of the first uplink power control parameter configuration information.

Wherein, the effective time of the first uplink power control parameter configuration information may be determined according to the subcarrier spacing of the first carrier or the subcarrier spacing of the second carrier. Preferably, the effective time of the first uplink power control parameter configuration information may be determined according to the smaller subcarrier interval among the subcarrier interval of the first carrier and the subcarrier interval of the second carrier, so that it can be avoided that the uplink power When the control parameter configuration information is not demodulated, power adjustment is performed on the corresponding uplink transmission, so as to avoid inappropriate power adjustment.

For example, suppose the network side configures the UE to send SRS on carrier 1 with a subcarrier interval of 15KHz and carrier 2 with a subcarrier of 60KHz, and receives the TPC command of the SRS on carrier 2 on the nth time slot of carrier 1, as shown in the figure. 2, the UE can start adjusting the carrier at the time slot length determined based on carrier 1, that is, the n+5th time slot (corresponding to the m+20th time slot of carrier 2, at which time the TPC command has been demodulated) 2 is the transmit power of the SRS. In addition, the UE can also start to adjust the transmission power of the SRS on carrier 2 at the time slot length determined based on carrier 2, that is, the m+5th time slot (corresponding to the n+1th time slot of carrier 1). At +1 timeslot, the TPC command may not be demodulated and thus may produce an inaccurate power adjustment.

In this embodiment of the present invention, when the transmit power varies between different uplink transmissions, the priority of the transmission time of different uplink transmissions occupied by the transition time of the terminal equipment may be as follows:

PRACH<PUSCH DMRS<short PUCCH<SRS<PUSCH, long PUCCH;

Or PRACH<SRS<PUSCH, PUCCH.

Optionally, when the transmission priorities of the uplink transmissions of the continuous transmission are the same, the transition time of the terminal equipment may be shared among the uplink transmissions of the continuous transmission, that is, evenly distributed among the adjacent uplink transmissions. When the transmission priorities of the uplink transmission of the continuous transmission are different, the transition time of the terminal device may be configured to the transmission time of the uplink transmission of the continuous transmission with a lower priority.

For example, assuming that the network side configures the UE to continuously transmit PUSCH and SRS in one time slot, and the absolute value of the power difference between SRS and PUSCH is less than a preset threshold of 3dB, the priority of the PUSCH transmission time occupied by the transition time of the terminal equipment If the priority is higher than that of the SRS, the guard interval does not need to be reserved between the PUSCH and the SRS, and the transition time of the UE is located at the transmission time of the PUSCH, as shown in FIG. 3A . Assuming that the absolute value of the power difference between SRS and PUSCH is greater than 3dB, the carrier frequency is greater than 6GHz, and the subcarrier interval is 120KHz, a guard interval of one symbol can be reserved between PUSCH and SRS, and the transition time of UE is located in this guard interval. , as shown in Figure 3B.

Referring to FIG. 4 , an embodiment of the present invention further provides a control method, applied to a network device, including the following steps:

Step 401: Send uplink power control parameter configuration information to a terminal device, so that the terminal device can control N uplink transmissions transmitted within a transmission time interval according to the uplink power control parameter configuration information.

The control is: controlling the transmit power of the N uplink transmissions, so that the absolute value of the power difference of every two consecutive uplink transmissions within the one transmission time interval is smaller than a first preset threshold or, control the transmission time of the N uplink transmissions, so that the absolute value of the power difference of the continuous transmissions in the one transmission time interval is greater than the second preset threshold value. Reserve protection between uplink transmissions interval; the N is a positive integer greater than or equal to 2.

The control method according to the embodiment of the present invention enables the terminal device to control the N uplink transmissions transmitted within a transmission time interval, so that the absolute value of the power difference between the uplink transmissions of every two consecutive transmissions in the transmission time interval is Smaller, to avoid power adjustment between uplink transmissions of continuous transmission, or to reserve a guard interval between uplink transmissions with a larger absolute value of the power difference of continuous transmissions within the transmission time interval, thereby reducing the uplink transmission process. The impact of the transition time of the terminal equipment in the middle is reduced, and the inter-symbol interference or signal distortion is reduced.

In this embodiment of the present invention, optionally, the N uplink transmissions include uplink channels of the same type and/or uplink reference signals of the same type.
