detailed description

The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

In a 5G communication system, the UE needs to adjust the transmission power of the uplink transmission before repeatedly transmitting the PUSCH in the time domain. For the power adjustment of the PUSCH, when the UE needs to send the PUSCH, it will use the power adjustment signal indicated by the power adjustment signaling based on the power adjustment signaling received before the predetermined time interval before the time domain position of the PUSCH is sent. The transmission power is adjusted, and then the above-mentioned PUSCH is transmitted with the transmission power.

However, since the above-mentioned predetermined time interval is a value configured by the network with a granularity of a slot. When the UE needs to adjust the transmission power of the uplink transmission, the UE needs to receive the power adjustment signaling of the base station at least N slots before the PUSCH transmission starts. That is, when the UE performs repeated PUSCH transmission in a time interval less than the predetermined time interval, it may cause the UE to be unable to adjust the transmission power. For example, when the UE performs repeated transmission of PUSCH with a mini-slot granularity, the UE may need to perform multiple repeated transmissions within a slot. At this time, the current power adjustment mechanism cannot flexibly support the UE to perform power adjustment during the repeated transmission of the mini-slot granularity, that is, the UE cannot perform transmission power adjustment during the repeated PUSCH transmission with the mini-slot granularity.

In view of the above problems, the embodiments of the present application provide a power adjustment method, terminal device, and network device. After receiving the first power adjustment signaling from the network device, the terminal device can adjust the uplink channel of the target location based on the first information The transmit power. Since the first information is used to indicate the target time interval, and the time interval between the receiving moment of the first power adjustment signaling and the target location is greater than or equal to the target time interval, thereby ensuring that the terminal device can adjust the transmit power of the target location and improve Communication efficiency and effectiveness.

n	Kn

It should be noted that the logo in Table 1 above is just an example. In practical applications, the logo is not limited to numbers, and may also be other logos such as English letters, which are not limited in this application.

Optionally, in the embodiment of the present application, the above-mentioned first information is used to indicate at least one of the following: a control resource set CORESET corresponding to the downlink control information (Downlink Control Information, DCI) carrying the first power adjustment signaling, and a bearer The search space corresponding to the DCI of the first power adjustment signaling, the format of the DCI carrying the first power adjustment signaling, and the wireless network temporary identifier of the DCI carrying the first power adjustment signaling (Radio Network Tempory Identity, RNTI) ).

For example, in the process of repeated PUSCH transmission by the UE, if the predetermined time interval includes the time interval K1 and the time interval K2, the terminal device may determine from K1 and K2 based on the DCI information carrying the first power adjustment signaling The target interval. For details, please refer to the following example:

Example 1: If the first power adjustment signaling is carried by DCI format 1, the terminal device determines that the target time interval is K1; if the first power adjustment signaling is carried by DCI format 2, the terminal device determines the target time interval For K2.

Example 2: If the DCI carrying the first power adjustment signaling is scrambled by RNTI1, the UE determines the target time interval to be K1; if the DCI carrying the power adjustment signaling is scrambled by RNTI2, the UE determines the target time The interval is K2.

Example 3: If the PDCCH where the DCI carrying the first power adjustment signaling is located is at CORESET1, the UE determines that the target time interval is K1; if the PDCCH where the DCI carrying the first power adjustment signaling is located is at CORESET2, the UE determines The target time interval is K2.

Example 4: If the PDCCH where the DCI carrying the first power adjustment signaling is located is in Search space 1, the UE determines the target time interval to be K1; if the PDCCH where the DCI carrying the first power adjustment signaling is located is in Search space 2, Then the UE determines that the target time interval is K2.

As shown in FIG. 3, the UE performs repeated PUSCH transmission, and the number of repeated transmissions is 4. After the UE receives TPC1 sent by the base station, the determined target time interval is K0, and the time interval between the reception time of TPC1 and the PUSCH transmission time i-1 is greater than K0. Therefore, the UE applies the power adjustment amount indicated by TPC1 to PUSCH transmission after PUSCH transmission time i-1. When the base station receives the PUSCH sent by the UE at PUSCH transmission time i-1, if the base station fails to decode the PUSCH i-1 transmission, the base station can adjust the transmit power of the UE and send a power adjustment instruction TPC2. After receiving TPC2 sent by the base station, the UE determines that the target time interval is K1. Since the time interval between the reception time of the TPC2 received by the UE and the PUSCH transmission time i+1 is not less than K1, the UE applies TPC2 to the PUSCH transmission PUSCH transmission after time i+1.

Step B1: The network device sends at least one second power adjustment signaling to the terminal device.

Step B2: The terminal device adjusts the transmit power of the uplink channel at the target location according to the first information, at least one second power adjustment signaling, and the first power adjustment signaling.

In the embodiment of the present application, based on the above step B1, the above-mentioned first information is used to instruct the terminal device to adjust the uplink channel of the target position according to the first information, at least one second power adjustment signaling and the first power adjustment signaling Transmit power. Wherein, a second power adjustment signaling indicates a power adjustment amount, and a first power adjustment signaling indicates a power adjustment amount.

Exemplarily, the first power adjustment signaling takes TPC1 as an example, the at least one second power adjustment signaling takes M TPC2 as an example, the power adjustment amount indicated by TPC1 is T1, and the power adjustment amounts indicated by M TPC2 are respectively For: T21, T22, T23, ..., T2M, all the above power adjustments of the terminal device are accumulated to obtain the target power adjustment T0, T0=T1+T21+T22+T23+...+T2M. In this way, the terminal device can adjust the transmission power of the uplink channel at the target position based on the target power adjustment amount T0.

Further optionally, before step B1, the method further includes:

Step B3: The terminal device obtains the second information.

Wherein, the above-mentioned second information is used to instruct the terminal device to receive the second power adjustment signaling sent by the network device within a predetermined time period before the receiving moment of the first power adjustment signaling.

In an example, the UE performs repeated PUSCH transmission as an example, the foregoing predetermined time period is from the KPUSCH (i-i0)-1 symbol before the PUSCH transmission time i-i0 to the KPUSCH before the PUSCH transmission time i (i) symbols.

Example 1: When PUSCH transmission is scheduled by DCI format 0_0 or DCI format 0_1, the above KPUSCH(i) is indicated by the DCI of the PUSCH according to the scheduled transmission time i, or received according to the PUSCH transmission time i Explicit/implicit indication in power adjustment instructions.

Example 2: When PUSCH transmission is semi-statically scheduled transmission, the above KPUSCH(i) is: according to the power adjustment instruction received before PUSCH transmission time i, or RRC signaling directly indicates the size of KPUSCH(i) Or, according to the configuration information of RRC signaling (for example, when the UE is configured with slot-level PUSCH repeated transmission, KPUSCH(i) is K1, and when the UE is configured with mini-slot level PUSCH repeated transmission, KPUSCH( i) is K2, K2<K1).
