Background

The Power Control adjustment state variable is a parameter that needs to be used when the terminal device determines the transmission Power of an uplink Channel, and the terminal device determines the Power Control adjustment state variable through a Power Control Command (TPC Command, for short) in a downlink Physical Control Channel (PDCCH, for short) sent by the network device, so as to determine the transmission Power of the uplink Channel through the Power Control adjustment state variable, which is also called a Power correction value. With the development of communication technology, a terminal device may transmit an uplink channel at a 1ms TTI and an sTTI (short TTI, which may be less than or equal to 0.5ms), and there is no method for determining a power control adjustment state variable of the uplink channel in a system with different TTI lengths in the prior art, so a method for determining the power control adjustment state variable is urgently needed at present.

The embodiment of the invention provides a method and a device for determining a power control adjustment state variable, which are used for determining the power control adjustment state variable of an uplink channel by terminal equipment in a system with different coexistence TTI lengths.

In order to achieve the above purpose, the embodiment of the invention adopts the following technical scheme:

in a first aspect, a method of determining a power control adjustment state variable is provided, the method comprising: the terminal equipment determines a first power control adjustment state variable, wherein the first power control adjustment state variable is a power control adjustment state variable of a first channel on first time domain resources, and the time length of the first time domain resources is less than or equal to one time slot; the terminal equipment determines a second power control adjustment state variable, wherein the second power control adjustment state variable is equal to the first power control adjustment state variable, the second power control adjustment state variable is a power control adjustment state variable of a second channel on a second time domain resource, the starting time of the second time domain resource is later than or equal to the starting time of the first time domain resource, and the time length of the first time domain resource is less than the time length of the second time domain resource.

The method provided by the first aspect may determine that the second power control adjustment state variable is equal to the first power control adjustment state variable when a certain condition is satisfied (that is, the starting time of the second time domain resource is later than or equal to the starting time of the first time domain resource, the time length of the first time domain resource is less than the time length of the second time domain resource, and the time length of the first time domain resource is less than or equal to one timeslot). And before the terminal equipment sends the second channel, the terminal equipment sends the first channel by adopting the transmitting power adjusted by the first power control adjustment state variable on the short time domain resource, and the network equipment adjusts the transmitting power to the value most suitable for the channel environment by the first power control adjustment state variable on the short time domain resource.

In one possible design, the method further includes: the terminal equipment receives a first power correction value and a second power correction value, wherein the first power correction value corresponds to a first channel, and the second power correction value corresponds to a second channel; or the terminal equipment receives a first power correction value, wherein the first power correction value corresponds to a first channel; or the terminal equipment receives a second power correction value, and the second power correction value corresponds to a second channel.

In this possible design, the terminal device may determine a first power control adjustment state variable according to the first power correction value; the terminal device may determine a second power control adjustment state variable according to the second power correction value when the first channel does not exist on the first time domain resource.

In one possible design, the terminal device receives the first power correction value and the second power correction value, and includes: the terminal equipment receives the first power correction value on the third time domain resource; and the terminal equipment receives the second power correction value on a fourth time domain resource, wherein the starting time of the fourth time domain resource is earlier than or equal to the starting time of the third time domain resource.

In this possible design, the terminal device does not determine the second power control adjustment state variable using the second power correction value prepared for determining the second power control adjustment state variable, but makes the second power control adjustment state variable equal to the first power control adjustment state variable, so that the second power correction value can be prevented from making the power of the second channel transmitted by the terminal device larger or smaller, and the determined second power control adjustment state variable can be made to more adapt to the current channel environment because the first power control adjustment state variable is the power control adjustment state variable determined according to the latest power correction value transmitted by the network device.

In one possible design, before the terminal device determines the second power control adjustment state variable, the method further includes: the terminal equipment determines that the time difference between the starting time of the first time domain resource and the starting time of the second time domain resource is greater than or equal to a time threshold value, and the time threshold value is predefined or configured by a high-level signaling.

In this possible design, the time threshold is set so that the terminal device has time to process the first power correction value.

In one possible design, before the terminal device determines the second power control adjustment state variable, the method further includes: and the terminal equipment receives first indication information, wherein the first indication information is used for indicating the terminal equipment to determine that the second power control adjustment state variable is equal to the first power control adjustment state variable.

In this possible design, the terminal device may perform the above method by the first indication information.

In this possible implementation, the object of not using the second power correction value may be achieved by discarding the second power correction value in the embodiment of the present invention.

In one possible embodiment, the first power correction value is less than or equal to a first threshold value.

In this possible implementation manner, when the first power correction value is less than or equal to the first threshold value, it may be considered that the channel condition is better, and the network device prepares to use the first power correction value before so that the terminal device uses a lower power to transmit the channel, but the network device has already transmitted the first power correction value at present, so that the terminal device may determine that the second power control adjustment state variable is equal to the first power control adjustment state variable.

In one possible design, the first power control adjustment state variable is less than or equal to the second threshold value.

In this possible implementation manner, when the first power control adjustment state variable is less than or equal to the second threshold, it may be considered that the channel condition is better, and therefore, the terminal device may determine that the second power control adjustment state variable is equal to the first power control adjustment state variable.

In one possible design, the first DCI is carried on a first DCI, the first DCI is located in a UESS of a first downlink physical control channel, the second DCI is carried on a second DCI, and the second DCI is located in a UESS of a second downlink physical control channel.

In the method provided by the second aspect, the network device sends the first indication information to the terminal device, so that when the terminal device meets a certain condition (that is, the starting time of the second time domain resource is later than or equal to the starting time of the first time domain resource, the time length of the first time domain resource is less than the time length of the second time domain resource, and the time length of the first time domain resource is less than or equal to one timeslot), it can be determined that the second power control adjustment state variable is equal to the first power control adjustment state variable, thereby solving the power control problem in the concurrent system of the sTTI and the 1ms TTI, and solving the problem of how to determine the power control adjustment state variable in the sTTI and the 1ms TTI system, or in the 2-symbol sTTI and the 7-symbol sTTI systems. And before the terminal equipment sends the second channel, the terminal equipment sends the first channel by adopting the transmitting power adjusted by the first power control adjustment state variable on the short time domain resource, and the network equipment adjusts the transmitting power to the value most suitable for the channel environment by the first power control adjustment state variable on the short time domain resource.

In one possible design, the method further includes: the network equipment sends second indication information to the terminal equipment, wherein the second indication information comprises at least one of a time threshold value, a first threshold value and a second threshold value; the time threshold is that the terminal equipment determines whether the second power control adjustment state variable is equal to the critical value of the first power control adjustment state variable according to the time difference, and the time difference is the difference between the starting time of the first time domain resource and the starting time of the second time domain resource; the first threshold value is used for determining whether the second power control adjustment state variable is equal to the critical value of the first power control adjustment state variable or not by the terminal equipment according to the first power correction value, and the first power correction value corresponds to the first channel; the second threshold is a threshold value for which the terminal device determines whether the second power control adjustment state variable is equal to the first power control adjustment state variable according to the first power control adjustment state.

In this possible implementation, the network device may enable the terminal device to have the time for processing the first power modification value by sending the time threshold to the terminal device; the determined second power control adjustment state variable may be made more adaptive to the current channel environment by transmitting the first threshold value and the second threshold value to the terminal device.

In one possible design, the method further includes: the network equipment sends a first power correction value on the third time domain resource, and the first power correction value corresponds to the first channel; and the network equipment sends a second power correction value on a fourth time domain resource, wherein the second power correction value corresponds to a second channel, and the starting time of the fourth time domain resource is earlier than or equal to the starting time of the third time domain resource.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

The method provided by the embodiment of the invention can be applied to a wireless communication system, for example: global System for Mobile communications (GSM) System, Code Division Multiple Access (CDMA) System, Wideband Code Division Multiple Access (WCDMA) System, General Packet Radio Service (GPRS) System, Universal Mobile Telecommunications System (UMTS), in particular for Long Term Evolution (LTE) System and its Evolution, Long Term Evolution-Advanced (LTE-a) System and its Evolution, and fifth generation (5G) Wireless communication System. In particular, the method can be applied to the sTTI technology. For the convenience of understanding, the LTE system is taken as an example, and the contents related to the present invention are briefly described below.

With the development of communication protocols, the scheduling interval of the physical layer which has the most obvious influence on the delay is smaller and smaller, in the initial WCDMA, the scheduling interval is 10ms, the scheduling interval in High-Speed Packet Access (HSPA) is shortened to 2ms, and the scheduling interval in LTE is shortened to 1 ms.

The small delay traffic requirement results in the LTE physical layer needing to introduce a shorter TTI frame structure to further shorten the scheduling interval. For example, the TTI length may be shortened from 1ms to between 1 symbol (symbol) and 1 slot (0.5 ms). The above mentioned symbols may be Orthogonal Frequency Division Multiplexing (OFDM) symbols or Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols in the LTE system, and may also be symbols in other communication systems.

sTTI transmission, i.e. signal transmission with a TTI less than or equal to 1 slot, for example, the TTI length is one of 1, 2, 3, 4, 5, 6, 7 symbols, or the TTI length is a combination of at least 2 different TTI lengths of 1, 2, 3, 4, 5, 6, 7 symbols, for example, 4 TTIs are included in 1ms, and the TTI lengths are 4, 3, 4, 3 symbols or a combination of 4, 3, 4 symbols or other different TTI lengths.

The TTI length of the uplink may be the same as the TTI length of the downlink, for example, both the TTI length of the uplink and the TTI length of the downlink are 2 symbols; the TTI length of the uplink may be longer than that of the downlink, for example, the TTI length of the uplink is 1 subframe, and the TTI length of the downlink is 2 symbols; the TTI length for the uplink may be shorter than the TTI length for the downlink, e.g., 4 symbols for the uplink and 7 symbols for the downlink.

In the existing 1ms TTI transmission, the RTT of data transmission is 8 ms. Referring to fig. 1, if a short TTI transmission technique is introduced, assuming that processing time is proportionally reduced compared to existing 1ms TTI scheduling, taking TTI length of 1 slot as an example, based on a Hybrid Automatic Repeat Request (HARQ) technique, a network device transmits data to a terminal device at slot 3, the terminal device feeds back an Acknowledgement Character (ACK) to the network device at slot 7 if the terminal device demodulates and decodes the received data correctly, the terminal device feeds back a Negative Acknowledgement Character (NACK) to the network device at slot 7 if the terminal device does not demodulate and decode the received data correctly, and the network device determines to perform data retransmission or retransmission processing on a downlink according to the received ACK/NACK at slot 11. The ACK or NACK fed back may also be collectively referred to as HARQ-ACK information. Therefore, when data transmission is performed in 1-slot TTI, RTT of data transmission is 8 slots, that is, 4ms, and the time delay is shortened by half compared with 8ms RTT transmitted in 1ms TTI.

The transmission of services in the LTE system is scheduled based on network equipment, and the basic time unit scheduled after introducing the sTTI technique is 1ms TTI or sTTI. The specific scheduling process is that the network device sends a Control Channel, such as a PDCCH or an Enhanced Physical Downlink Control Channel (EPDCCH), and the terminal device detects the Control Channel in a subframe and receives a Downlink data Channel or sends an uplink data Channel according to scheduling information carried in the detected Control Channel. The network device mainly sends scheduling information to the terminal device through a Downlink Control Indicator (DCI for short) carried by a Downlink Control channel. The terminal device monitors (i.e. detects) whether the DCI belonging to the terminal device exists in the search space formed by the candidate downlink control channels, and when the DCI belonging to the terminal device is detected, the terminal device can perform data transmission according to the scheduling information of the data transmission in the DCI. The process of detecting the DCI in the search space candidate downlink control channels by the terminal device is called blind detection, and when the search space is larger, or the number of candidate downlink control channels to be detected in the fixed search space is more, the number of blind detections is more.

In specific implementation, the search space for the terminal device to monitor the DCI is formed by combining one or more candidate downlink control channels, and each candidate downlink control channel can be used for carrying the DCI. In short, the search space is a set of candidate downlink control channels. The terminal device needs to monitor the candidate downlink control channels, so the search space is also the set of candidate downlink control channels monitored by the terminal device. Illustratively, the search space is composed of one or more PDCCHs, which may be referred to as a PDCCH search space. Illustratively, the search space is composed of one or more EPDCCH, and may be referred to as an EPDCCH search space. Illustratively, the search space is comprised of one or more sPDCCH, which may be referred to as an sPDCCH search space. The Search Space includes two types of Common Search Space (CSS) and UE Specific Search Space (UESS).

Scheduling information UL DCI (Uplink DCI ) of a PDCCH of a control Channel (E) indicates transmission of a Physical Uplink Shared Channel (PUSCH for short), and the UL DCI carries a TPC command of the PUSCH; scheduling information DL DCI (Downlink DCI) of a PDCCH of the Control Channel (E) indicates reception of a Physical Downlink Shared Channel (PDSCH), and the DL DCI carries a TPC command of a Physical Uplink Control Channel (PUCCH).

Specifically, the power of the terminal device for sending the PUSCH in the subframe i is:

wherein, P_CMAX,c(i) Maximum value of transmission power allowed for terminal equipment, M_PUSCH,c(i) Allocating a bandwidth value, P, for PUSCH resources_{O_PUSCH,c}(j) PUSCH initial power, PL configured for higher layer signaling_cFor the downlink path loss estimation, α_c(j) Which is a scaling factor of the downlink path loss estimate,

is modulation mode offset and is used for controlling the power when information is transmitted in the PUSCH, if the PUSCH power control adjustment state is accumulative, f_c(i)＝f_c(i-1)+δ_PUSCH,c(i-K_PUSCH) Wherein f is_c(i) Adjusting state for PUSCH power control of current subframe i, f_c(i) PUSCH Power control adjustment State + subframe i-K for subframe i-1_PUSCHReceived power correction value, δ_PUSCH,cI.e. the power correction value. If the PUSCH power control adjustment state is not accumulative, then f_c(i)＝δ_PUSCH,c(i-K_PUSCH). Thus, the PUSCH power control adjustment state f_c(i) Is a parameter for determining the power at which the terminal device transmits PUSCH in subframe i.

The power of the terminal equipment for sending the PUCCH in the subframe i is as follows:

wherein, P_CMAX,c(i) Maximum value of transmission power, Δ, allowed for terminal equipment_{F_PUCCH}(F) Configured by higher layer signaling for PUCCH format power offset value, Delta_TxD(F') is the power offset value, h (n), configured by higher layer signaling for multi-antenna transmission PUCCH_CQI,n_HARQ,n_SR) Offset value, P, for PUCCH carrying control information_{O_PUCCH}The PUCCH initial power configured for higher layer signaling,

wherein g (i) is the PUCCH power control adjustment state of the current subframe i, and g (i) is the PUCCH power control adjustment state of the subframe i-1 + subframe i-k_mReceived power correction value, δ_PUCCHThe power correction value. As can be seen, g (i) is a parameter for determining the power of the terminal device for transmitting the PUCCH in subframe i.

Taking the uplink channel as the PUSCH, referring to fig. 2, the power correction value (denoted as T1) of the PUSCH of the subframe n-1 is carried in the PDCCH of the subframe n-5, and the power correction value (denoted as T2) of the PUSCH of the subframe n is carried in the PDCCH of the subframe n-4. Power control adjustment state variable f of PUSCH of subframe n_c(n)＝f_c(n-1)+T2，f_c(n-1)＝f_c(n-2) + T1 wherein f_c(n-1) Power control adjustment State variable of PUSCH for subframe n-1, f_c(n-2) Power control adjustment State variable for PUSCH of subframe n-2, when no PUSCH is transmitted on subframe n-2, then f_c(n-2) may be the power control adjustment state variable of the PUSCH that precedes subframe n-1 and is closest to the PUSCH of subframe n-1, and if subframe n-1 is the first PUSCH after reconfiguration, f is_c(n-2)＝f_c(0)，f_c(0) The state variables are adjusted for initial power control.

Referring to fig. 2, in the example shown in fig. 2, a Transmission Time Interval (TTI) is 1ms, in which case T1 must be transmitted before T2, and T1 must also be validated before T2.

However, when the terminal device transmits the Uplink Channel in 1ms TTI and sTTI, when T1 takes effect before T2, T1 is not necessarily transmitted before T2, and therefore the transmission time of T1 and T2 may cause the terminal device to transmit PUSCH (or short Physical Uplink Channel, abbreviated as sPUSCH)) with a power that is too large or too small, so that power is wasted or transmission fails.

Specifically, referring to fig. 3, the network device schedules the uplink channel transmitted by the terminal device on the subframe n-4 in the TTI of 1ms in the subframe n, and the network device schedules the terminal device to transmit the uplink channel in the subframes n-3 to n-1 in the TTI of s. Since the Round-Trip Time (RTT) of the sTTI is much shorter than the RTT of the 1ms TTI, a situation may arise as shown in fig. 3, i.e. T2 shown in fig. 3 takes effect before T1. In this case, f_c(n)＝f_c(n-1) + T1, since the terminal device does not send PUSCH in subframe n-1, f_c(n)＝f_c(time slot 2 of subframe n-2) + T1, where f_c(slot 2 of subframe n-2) ═ f_c(x) + T2, therefore f_c(n)＝f_c(x) + T2+ T1 wherein f_c(x) The power control adjustment state variable may be the power control adjustment state variable of the PUSCH (or the sPUSCH) that precedes slot 2 of subframe n-2 and is closest to the PUSCH of slot 2 of subframe n-2, and if slot 2 of subframe n-2 is the first sPUSCH after reconfiguration, f is_c(slot 2 of subframe n-2) ═ f_c(0)，f_c(0) For the initial power Control adjustment state variable, the power correction value T1 of the PUSCH of the subframe n is carried in the PDCCH of the subframe n-4, and the power correction value T2 of the sPUSCH of the slot 2 of the subframe n-2 is carried in the short Physical downlink Control Channel (sPDCCH for short) of the slot 2 of the subframe n-4.

Referring to fig. 3, when the network device schedules the terminal device to transmit the uplink channel on the 1ms TTI, it considers that the subframes n-1 to n-4 are transmitted without PUSCH or sPUSCH, and therefore, the network device intends to make f be_c(n)＝f_c(n-1)+T1＝f_c(x) + T1, but with sUSCH transmission in subframes n-1 through n-4 due to the existence of sTTI, so that f_c(n)＝f_c(n-1) + T1 wherein f_c(n-1)＝f_c(time slot 2 of sub-frame n-2), f_c(slot 2 of subframe n-2) ═ f_c(x) + T2, therefore f_c(n)＝f_c(x) + T2+ T1. That is, if the method in the prior art is adopted to calculate f of PUSCH of subframe n_c(n) f, which is finally calculated by the terminal equipment_c(n) expected from the network device_c(n) are different, which may cause the terminal device to transmit PUSCH with larger or smaller power, so as to waste power or fail transmission.

Currently, when 2 or 3 uplink symbols transmit sTTI, the specific structure is 322223, that is, one subframe is divided into 6 short TTIs. Symbol 0 of the first slot, symbol 1 of the first slot and symbol 2 of the first slot are sTTI _1, symbol 3 of the first slot and symbol 4 of the first slot are sTTI _2, and symbol 5 of the first slot and symbol 6 of the first slot are sTTI _ 3. Symbol 0 of the second slot, symbol 1 of the second slot is sTTI _4, symbol 2 of the second slot and symbol 3 of the second slot are sTTI _5, symbol 4 of the second slot, symbol 5 of the second slot and symbol 6 of the second slot are sTTI _ 6. See in particular fig. 3-a.

By analogy, referring to fig. 3-a, when the network device schedules the terminal device to transmit the uplink channel on the timeslot m TTI, it considers that the timeslots m-1 to m-4 are transmitted by the sPUSCH without 2 symbols or 3 symbols, and therefore, the network device intends to make f_c(m)＝f_c(m-1)+T1＝f_c(x) + T1, but with 2-symbol or 3-symbol sPUSCH transmission in slot m-1 to slot m-4 due to the presence of 2-symbol or 3-symbol sTTI, so that f_c(m)＝f_c(m-1) + T1, wherein f_c(m-1)＝f_c(sTTI _1, f on slot m-2)_c(sTTI _1 in slot m-2) ═ f_c(x) + T2, therefore f_c(m)＝f_c(x) + T2+ T1. That is, if the method in the prior art is adopted to calculate f of sUSCH of time slot m_c(m) such that f is finally calculated by the terminal device_c(m) expected from the network device_c(m) are different and may result in the terminal device transmitting sP for 1 slot TTIThe power of the USCH is so large or small that power is wasted or transmission fails.

An embodiment of the present invention provides a method for determining a power control adjustment state variable, as shown in fig. 7, where the method includes:

701. the terminal equipment determines a first power control adjustment state variable, wherein the first power control adjustment state variable is a power control adjustment state variable of a first channel on first time domain resources, and the time length of the first time domain resources is less than or equal to one time slot.

The first time domain resource may be one time slot or x symbols, where x is an integer less than or equal to 7 when the subcarrier spacing is 15khz, and x may be an integer less than or equal to 7 or an integer greater than 7 when the subcarrier spacing is greater than 15 khz.

702. The terminal equipment determines a second power control adjustment state variable, wherein the second power control adjustment state variable is equal to the first power control adjustment state variable, the second power control adjustment state variable is a power control adjustment state variable of a second channel on a second time domain resource, the starting time of the second time domain resource is later than or equal to the starting time of the first time domain resource, and the time length of the first time domain resource is less than the time length of the second time domain resource.

The second time domain resource may be 1ms, or may be other time lengths longer than the first time domain resource. The first time domain resource may be located in the second time domain resource or within 3ms before the second time domain resource, for example, taking fig. 3 as an example, when the second time domain resource is the subframe n, the first time domain resource may be located in the subframe n, the subframe n-1, the subframe n-2, and the subframe n-3. The first time domain resource may also be located in the second time domain resource or within 4ms before the second time domain resource, for example, taking fig. 3 as an example, when the second time domain resource is the subframe n, the first time domain resource may be located in the subframe n, the subframe n-1, the subframe n-2, the subframe n-3, and the subframe n-4. It should be noted that the first time domain resource may completely overlap with the second time domain resource, or partially overlap with the second time domain resource.

Specifically, the relationship between the first time domain resource and the second time domain resource may be shown in fig. 8, where L is greater than or equal to 0, the first time domain resource is taken as an example in fig. 8 to be drawn, and fig. 8 shows three possible time relationships between the first time domain resource and the second time domain resource.

It should be noted that, when there are multiple first time domain resources before the second time domain resource, the second power control adjustment state variable is equal to the power control adjustment state variable of the first channel of the first time domain resource closest to the second time domain resource. The first time domain resource closest to the second time domain resource may be the first time domain resource with the smallest difference between the start time and the start time of the second time domain resource, or the first time domain resource with the smallest difference between the start time and the start time of the second time domain resource when the first time domain resource and the second time domain resource are not overlapped at all.

For example, referring to fig. 9, slot 2 of subframe n-2 and slot 1 of subframe n-1 are both first time domain resources, and the second power control adjustment state variable is equal to the power control adjustment state variable of the first channel of slot 1 of subframe n-1. Correspondingly, referring to fig. 3-a, sTTI _2 of subframe n-2 and sTTI _4 of subframe n-1 may also be both first time domain resources. It can be understood that the number of the first time domain resources before the second time domain resource may be an integer greater than or equal to 1, the time lengths of the plurality of first time domain resources may be the same or different, and one first channel is on one first time domain resource. For example, there are two first time domain resources a and B, and the first time domain resources a and B may be different lengths, for example, the first time domain resource a may be a 2-symbol or 3-symbol time domain resource, and the first time domain resource B may be a 7-symbol time domain resource.

It is to be understood that when the starting time of the second time domain resource is earlier than the starting time of the first time domain resource, or when the time length of the first time domain resource is equal to the time length of the second time domain resource, or the time length of the first time domain resource is greater than one time slot, the terminal device determines the second power control adjustment state variable using the power correction value used to determine the second power control adjustment state variable, instead of directly making the second power control adjustment state variable equal to the first power control adjustment state variable. In this case, the power correction value used for determining the second power control adjustment state variable is the latest power correction value sent by the network device, and if only the first power control adjustment state variable is used, the current channel environment is not suitable.

Optionally, the first channel and the second channel are both uplink data channels. The first channel and the second channel may both be uplink control channels. Specifically, the first channel may be sPUCCH, and the second channel is PUCCH; or, the first channel may be an sPUSCH, and the second channel is a PUSCH; or the first channel is a 2-symbol sUSCH, and the second channel is a 7-symbol sUSCH; or the first channel is a 2-symbol sPUCCH and the second channel is a 7-symbol sPUCCH.

According to the method provided by the embodiment of the invention, taking fig. 3 as an example, if the subframe n is the second time domain resource and the time slot 2 of the subframe n-2 is the first time domain resource, f is_c(n)＝f_c(slot 2 of subframe n-2) ═ f_c(x) + T2, it should be noted that T2 is the power correction value of sUSCH determined by the network device for the terminal device in slot 2 of sub-frame n-4, where f in the prior art is not used again_c(n)＝f_c(slot 2 of subframe n-2) + T1 ═ f_c(x) + T2+ T1. It will be appreciated that when T2 is not present in fig. 3, the terminal device determines f using prior art techniques_c(n) is specifically f_c(n)＝f_c(x)+T1。

The method provided by the embodiment of the invention can determine that the second power control adjustment state variable is equal to the first power control adjustment state variable when certain conditions are met (namely the starting time of the second time domain resource is later than or equal to the starting time of the first time domain resource, the time length of the first time domain resource is less than the time length of the second time domain resource, and the time length of the first time domain resource is less than or equal to one time slot), so that the power control problem in a system with both the sTTI and the 1ms TTI is solved, and the problem of how to determine the power control adjustment state variable in the system with the sTTI and the 1ms TTI or in the system with the 2-symbol sTTI and the 7-symbol sTTI is solved. And before the terminal equipment sends the second channel, the terminal equipment sends the first channel by adopting the transmitting power adjusted by the first power control adjustment state variable on the short time domain resource, and the network equipment adjusts the transmitting power to the value most suitable for the channel environment by the first power control adjustment state variable on the short time domain resource.

Optionally, the method may further include: the terminal equipment receives a first power correction value and a second power correction value, wherein the first power correction value corresponds to a first channel, and the second power correction value corresponds to a second channel; or the terminal equipment receives a first power correction value, wherein the first power correction value corresponds to a first channel; or the terminal equipment receives a second power correction value, and the second power correction value corresponds to a second channel.

The first power correction value is used to determine a power control adjustment state variable (i.e., a first power control adjustment state variable) of the first channel, that is, the terminal device determines the first power control adjustment state variable according to the first power correction value. Illustratively, taking fig. 3 as an example, T2 is a first power correction value, and the first power control adjusts the state variable f_c(slot 2 of subframe n-2) ═ f_c(x) + T2. In the prior art, the second power correction value is used to determine the power control adjustment state variable of the second channel (i.e. the second power control adjustment state variable), but in the solution of the present invention, it may be understood that the second power correction value is prepared to determine the power control adjustment state variable of the second channel, if the terminal device receives at least one first power correction value, the terminal device does not use the second power correction value when determining the second power control adjustment state variable, and if the terminal device does not receive the first power correction value, the terminal device determines the second power control adjustment state variable using the second power correction value. In this case, the number of the first and second terminals,the terminal equipment does not determine the second power control adjustment state variable by using the second power correction value prepared for determining the second power control adjustment state variable any more, but the second power control adjustment state variable is equal to the first power control adjustment state variable, so that the second power correction value can be prevented from causing the power of the second channel transmitted by the terminal equipment to be larger or smaller, and the determined second power control adjustment state variable can be more adaptive to the current channel environment because the first power control adjustment state variable is the power control adjustment state variable determined according to the latest power correction value transmitted by the network equipment.

Optionally, the method may further include: the network equipment sends a first power correction value on the third time domain resource, and the first power correction value corresponds to the first channel; and the network equipment sends a second power correction value on a fourth time domain resource, wherein the second power correction value corresponds to a second channel, and the starting time of the fourth time domain resource is earlier than or equal to the starting time of the third time domain resource.

Optionally, the receiving, by the terminal device, the first power correction value and the second power correction value includes: the terminal equipment receives the first power correction value on the third time domain resource; and the terminal equipment receives the second power correction value on a fourth time domain resource, wherein the starting time of the fourth time domain resource is earlier than or equal to the starting time of the third time domain resource.

Illustratively, referring to FIG. 3, slot 2 of sub-frame n-4 is the third time domain resource and sub-frame n-4 is the fourth time domain resource, i.e., the first power correction value is sent later than the second power correction value.

It is to be understood that when the start time of the fourth time domain resource is earlier than or equal to the start time of the third time domain resource, then the terminal device is determining that the second power control adjustment state variable is equal to the first power control state variable. The second power correction value is not used at this time. In this case, the terminal device does not determine the second power control adjustment state variable by using the second power control adjustment state variable prepared for determining the second power correction value, but makes the second power control adjustment state variable equal to the first power control adjustment state variable, so that it is possible to prevent the second power correction value from making the power of the terminal device for transmitting the second channel larger or smaller, and it is possible to make the determined second power control adjustment state variable more adaptive to the current channel environment because the first power control adjustment state variable is the power control adjustment state variable determined according to the latest power correction value transmitted by the network device.

Optionally, when the starting time of the fourth time domain resource is later than the starting time of the third time domain resource, the terminal device determines the second power control adjustment state variable by using the second power correction value.

Specifically, the starting time of the fourth time domain resource is earlier than or equal to the starting time of the third time domain resource, the starting time of the third time domain resource is earlier than or equal to the starting time of the first time domain resource, and the starting time of the first time domain resource is earlier than or equal to the starting time of the second time domain resource.

Specifically, as shown in fig. 9, the network device may send a plurality of first power correction values, where the number of the first power correction values may be an integer greater than or equal to 1, and the plurality of first power correction values may be the same or different. Optionally, at least one first power correction value corresponds to one first time domain resource, and the at least one first power correction value is used to calculate a power control adjustment state variable of a first channel of the first time domain resource corresponding to the first power correction value. Optionally, one first power modification value corresponds to at least one first time domain resource, and one first power modification value is used to calculate a power control adjustment state variable of at least one first channel of the at least one first time domain resource corresponding to the first power modification value.

Optionally, the first power correction value is carried in the first DCI, the first DCI is located in the UESS of the first downlink physical control channel, the second power correction value is carried in the second DCI, and the second DCI is located in the UESS of the second downlink physical control channel.

In the embodiment of the present invention, the first downlink physical control channel may be an sPDCCH or a PDCCH, and the second downlink physical control channel may be a PDCCH or an EPDCCH. The first DCI is carried on the first downlink physical control channel, and the second DCI is carried on the second downlink physical control channel.

The terminal equipment monitors first DCI in a UESS of a first downlink physical control channel, determines a first power correction value according to the monitored first DCI, monitors second DCI in a UESS of a second downlink physical control channel, and determines a second power correction value according to the monitored second DCI. Correspondingly, the network device sends the first DCI in the UESS of the first downlink physical control channel, and sends the second DCI in the UESS of the second downlink physical control channel.

For example, referring to fig. 3, the first power modification value is carried in the first DCI, where the first DCI is located in the UESS of the first downlink physical control channel in slot 2 of subframe n-4, and the second power modification value is carried in the second DCI, where the second DCI is located in the UESS of the second downlink physical control channel of subframe n-4.

Optionally, the second power correction value is a non-zero value, i.e. the second power correction value is not equal to 0. When the second power correction value is not zero, then the terminal device determines that the second power control adjustment state variable is equal to the first power control state variable. The second power correction value is not used at this time. It should be noted that, when the second power correction value is zero, the second power control adjustment state variable calculated by using the second power correction value according to the prior art and the second power control adjustment state variable calculated without using the second power correction value according to the present invention are the same.

Optionally, the method may further include: the terminal device discards the second power correction value.

In the embodiment of the present invention, since the second power correction value is not the latest power correction value, the second power correction value may be discarded regardless of whether the second power correction value is 0 or not.

Optionally, before the terminal device discards the second power correction value, the method further includes: and the terminal equipment receives third indication information, wherein the third indication information is used for indicating the terminal equipment to discard the second power correction value.

Specifically, the terminal device may determine to discard the second power correction value based on the third indication information sent by the network device. The third indication information may be configured by the network device through higher layer signaling. Higher layer signaling may refer to: the high-level protocol layer is at least one protocol layer in each protocol layer above the physical layer. The higher layer protocol layer may specifically be at least one of the following protocol layers: a MAC (Medium Access Control) layer, an RLC (Radio Link Control) layer, a PDCP (Packet Data Convergence Protocol) layer, an RRC (Radio Resource Control) layer, and an NAS (Non Access Stratum) layer.

Optionally, before step 702, the method may further include: and the terminal equipment receives first indication information, wherein the first indication information is used for indicating the terminal equipment to determine that the second power control adjustment state variable is equal to the first power control adjustment state variable.

Specifically, the terminal device determining the second power control adjustment state variable by using the method of the embodiment of the present invention may be determined based on the first indication information sent by the network device. The first indication information may be sent by the network device through higher layer signaling.

In this case, the method may further include: the network equipment sends the first indication information to the terminal equipment.

Optionally, before the network device sends the first indication information to the terminal device, the method may further include: the network device determines first indication information. It should be noted that, before the network device sends the first indication information, the network device may or may not determine the first indication information.

Optionally, before step 702, the method may further include: the terminal equipment determines that the time difference between the starting time of the first time domain resource and the starting time of the second time domain resource is greater than or equal to a time threshold value, and the time threshold value is predefined or configured by a high-level signaling.

Considering that the terminal device needs processing time after receiving the first power correction value, a time threshold may be determined for the scheme, and the second power control adjustment state variable may be made equal to the first power control adjustment state variable only if a time difference between a start time of the first time domain resource and a start time of the second time domain resource is greater than or equal to the time threshold. It can be understood that, if the time difference between the starting time of the first time domain resource and the starting time of the second time domain resource is smaller than the time threshold, the terminal device does not consider the first power control adjustment state variable when calculating the second power control adjustment state variable.

The time domain threshold may be 1ms, or 2ms, or 3ms, or 1.5ms, or 2.5ms, or 0.5ms, or 2 symbols, or 3 symbols, or 7 symbols, or 21 symbols, etc.

Illustratively, referring to fig. 3, the second time domain resource is subframe n, the first time domain resource is slot 2 of subframe n-2, and if the time threshold is 1ms, f is_c(n)＝f_c(slot 2 of subframe n-2), if the time threshold is 1.5ms, the second power control adjustment state variable is equal to the sum of the power control adjustment state variable of the PUSCH(s) closest to the sPUSCH of subframe n-1 and preceding subframe n-1 and the second power correction value.

When there are a plurality of first time domain resources before the second time domain resource, there are three possible time relationships between a first time domain resource a (the first time domain resource a may be any one of the plurality of first time domain resources) and a first time domain resource B (the first time domain resource B may be any one of the plurality of first time domain resources) in the plurality of first time domain resources:

possibility 1: and if the time difference between the starting time of the first time domain resource A and the starting time of the second time domain resource is greater than or equal to the time threshold, and the time difference between the starting time of the first time domain resource B and the starting time of the second time domain resource is less than the time threshold, the second power control adjustment state variable is equal to the power control adjustment state variable of the sUSCH of the first time domain resource A. Illustratively, referring to fig. 10, the second time domain resource is subframe n, the first time domain resource a is slot 1 of subframe n-2, the first time domain resource B is slot 1 of subframe n-1, and if the time threshold is 1.5ms or 1ms, the second power control adjustment state variable is equal to the power control adjustment state variable of the sPUSCH in slot 1 of subframe n-2. For another example, referring to fig. 3-B, the second time domain resource is timeslot m, the first time domain resource a is sTTI _2 of subframe n-2, the first time domain resource B is sTTI _4 of subframe n-1, and if the time threshold is 1.5ms, the second power control adjustment state variable is equal to the power control adjustment state variable of the sPUSCH of sTTI _2 of subframe n-2.

Possibility 2: the time difference between the starting time of the first time domain resource a and the starting time of the second time domain resource is greater than or equal to the time threshold, and the time difference between the starting time of the first time domain resource B and the starting time of the second time domain resource is greater than or equal to the time threshold, then the second power control adjustment state variable is equal to the power control adjustment state variable of the sPUSCH of the first time domain resource B, that is, the second power control adjustment state variable is the power control adjustment state variable of the sPUSCH of the first time domain resource whose time difference between the last starting time and the starting time of the second time domain resource is greater than or equal to the time threshold. Illustratively, referring to fig. 10, the second time domain resource is a subframe n, the first time domain resource a is a slot 1 of a subframe n-2, the first time domain resource B is a slot 1 of a subframe n-1, and if the time threshold is 1ms, the second power control adjustment state variable is equal to the power control adjustment state variable of the sPUSCH of the slot 1 of the subframe n-1. For another example, referring to fig. 3-B, the second time domain resource is timeslot m, the first time domain resource a is sTTI _2 of subframe n-2, the first time domain resource B is sTTI _4 of subframe n-1, and if the time threshold is 0.5ms, the second power control adjustment state variable is equal to the power control adjustment state variable of the sPUSCH of sTTI _4 of subframe n-1.

Possibility 3: and if no other first time domain resource exists, the second power control adjustment state variable is determined according to a second power correction value in the prior art. Illustratively, referring to fig. 11, the second time domain resource is subframe n, the first time domain resource a is slot 1 of subframe n-1, the first time domain resource B is slot 2 of subframe n-1, and if the time threshold is 1.5ms or 1ms, the second power control adjustment state variable is equal to the sum of the power control adjustment state variable of the PUSCH(s) closest to the sPUSCH of subframe n-1 before subframe n-1 and the second power correction value. For another example, referring to fig. 3-B, the second time domain resource is time slot m, the first time domain resource a is sTTI _2 of subframe n-1, the first time domain resource B is sTTI _4 of subframe n-2, and if the time threshold is 2ms, the second power control adjustment state variable is equal to the sum of the power control adjustment state variable of the PUSCH(s) before subframe n-2 and closest to the sPUSCH of subframe n-2 and the second power correction value.

Optionally, the first power correction value is smaller than or equal to the first threshold value. The first threshold may be predefined or configured by high layer signaling, and for example, the first threshold may be 0, or may be a value not equal to 0. The first threshold value may be-1, or-2, or-4, or 1, or 2, or 4, etc.

It should be noted that, when the first power correction value is smaller than or equal to the first threshold value, the channel condition may be considered to be better, and the network device prepares to use the first power correction value before so that the terminal device uses a lower power to transmit the channel, but the network device has already transmitted the first power correction value at present, and therefore, the terminal device can ensure that the second power correction value is not used when the second power control adjustment state variable is determined to be equal to the first power control adjustment state variable, the second power correction value can be prevented from causing the power of the second channel transmitted by the terminal device to be smaller, and since the first power control adjustment state variable is a power control adjustment state variable determined based on the most recent power correction value transmitted by the network device, thereby making it possible to make the determined second power control adjustment state variable more adaptive to the current channel environment. When the first power correction value is larger than the first threshold value and the channel condition is considered to be poor, the network equipment prepares to use the first power correction value before so that the terminal equipment adopts higher power to transmit the channel, and the transmission success rate of the channel is improved. Although the network device has already sent the first power correction value at present, in order to ensure the sending success rate of the second channel, the terminal device uses the second power correction value to determine the second power control adjustment state variable, so that the sending success rate of the second channel can be ensured by sending the second channel with higher power.

For example, when the first power correction value is less than or equal to 0, which indicates that the network device has reduced the power of the terminal device for transmitting the first channel, it may be determined that the channel condition determined by the network device in the third time domain resource is better, and therefore, the second power control adjustment state variable may be equal to the first power control adjustment state variable. When the first power correction value is greater than 0, it indicates that the network device increases the power of the terminal device for transmitting the first channel, and it may be determined that the condition of the channel determined by the network device in the third time domain resource is not good, and then it may be expected that the condition of the channel in the second time domain resource is also not good, and a method in the prior art may be used to determine the second power control adjustment state variable, that is, the second power control adjustment state variable is the first power control adjustment state variable + the second power correction value, so as to improve the transmission success rate of the second channel.

Optionally, the first power control adjustment state variable is less than or equal to the second threshold value.

The second threshold may be predefined or configured by higher layer signaling, and for example, the second threshold may be 0 or a value different from 0. The second threshold value may be-1, or-2, or-4, or 1, or 2, or 4, etc.

Specifically, when the first power control adjustment state variable is less than or equal to the second threshold, it may be considered that the channel condition is better, and therefore, the terminal device may determine that the second power control adjustment state variable is equal to the first power control adjustment state variable, and at this time, the second power correction value is not used, which may prevent the second power correction value from causing the terminal device to transmit a larger or smaller power of the second channel, and since the first power control adjustment state variable is the power control adjustment state variable determined according to the latest power correction value transmitted by the network device, the determined second power control adjustment state variable may be more adapted to the current channel environment. When the first power control adjustment state variable is larger than the first threshold value and the channel condition is considered to be bad, and when the second power correction value is larger than 0, the terminal equipment determines the second power control adjustment state variable by using the second power correction value, so that the second channel can be transmitted by adopting higher power to ensure the transmission success rate of the second channel.

For example, when the first power control adjustment state variable is less than or equal to 0, it indicates that the channel condition of the third time domain resource is better, and therefore, the second power control adjustment state variable may be made equal to the first power control adjustment state variable. When the first power control adjustment state variable is greater than 0, which indicates that the channel condition of the third time domain resource is not good, and then the channel condition of the second time domain resource is not good, and when the second power correction value is greater than 0, the method in the prior art may be used to determine the second power control adjustment state variable, that is, the second power control adjustment state variable is equal to the first power control adjustment state variable + the second power correction value, so as to improve the transmission success rate of the second channel.

In order to make the two alternative methods more clear, the second power control adjustment state variable determined in different situations is summarized in table 1, wherein the second power correction value is greater than 0, and the first threshold value and the second threshold value are both 0.

TABLE 1

Optionally, both the first power correction value and the second power correction value are less than or equal to 0.

Specifically, when both the first power correction value and the second power correction value are less than or equal to 0, it may be determined that the network device has adapted to the current channel through the first power correction value, and therefore, the terminal device may determine that the second power control adjustment state variable is equal to the first power control state variable, and at this time, the second power correction value is not used, which may prevent the second power correction value from making the power of the terminal device for transmitting the second channel smaller, and may further enable the determined second power control adjustment state variable to adapt to the current channel environment because the first power control adjustment state variable is the power control adjustment state variable determined according to the latest power correction value transmitted by the network device. When the first power correction value is greater than 0 and the second power correction value is less than or equal to 0, or when the first power correction value is less than or equal to 0 and the second power correction value is greater than 0, or when the first power correction value is greater than 0 and the second power correction value is greater than 0, the power requirements of the first channel and the second channel may be different, and at this time, the terminal device determines the second power control adjustment state variable using the second power correction value, so that the second channel can be transmitted by using more appropriate power.

Optionally, both the first power correction value and the second power correction value are greater than or equal to 0.

Specifically, when both the first power correction value and the second power correction value are greater than or equal to 0, it may be determined that the network device has adapted to the current channel through the first power correction value, and therefore, the terminal device may determine that the second power control adjustment state variable is equal to the first power control state variable, and at this time, the second power correction value is not used, which may prevent the second power correction value from causing the power of the terminal device for transmitting the second channel to be larger, and may further enable the determined second power control adjustment state variable to adapt to the current channel environment because the first power control adjustment state variable is the power control adjustment state variable determined according to the latest power correction value transmitted by the network device. When the first power correction value is greater than or equal to 0 and the second power correction value is less than 0, or when the first power correction value is less than 0 and the second power correction value is greater than or equal to 0, or when the first power correction value is less than 0 and the second power correction value is less than 0, the power requirements of the first channel and the second channel may be different, and then the terminal device determines the second power control adjustment state variable using the second power correction value, so that the second channel can be transmitted by using more appropriate power.

Optionally, the method may further include: the network equipment sends second indication information to the terminal equipment, wherein the second indication information comprises at least one of a time threshold value, a first threshold value and a second threshold value; the time threshold is that the terminal equipment determines whether the second power control adjustment state variable is equal to the critical value of the first power control adjustment state variable according to the time difference, and the time difference is the difference between the starting time of the first time domain resource and the starting time of the second time domain resource; the first threshold value is used for determining whether the second power control adjustment state variable is equal to the critical value of the first power control adjustment state variable or not by the terminal equipment according to the first power correction value, and the first power correction value corresponds to the first channel; the second threshold is a threshold value for which the terminal device determines whether the second power control adjustment state variable is equal to the first power control adjustment state variable according to the first power control adjustment state.

Illustratively, the second indication information may be configured by the network device through higher layer signaling. In the embodiments of the present invention, the drawings are drawn by taking the first channel as the sPUSCH and the second channel as the PUSCH as an example. Specifically, referring to fig. 12, when the first channel is sPUCCH and the second channel is PUCCH, subframe n is the second time domain resource, and slot 2 of subframe n-2 is the first time domain resource, then the second power control adjustment state variable g (n) ═ g (slot 2 of subframe n-2).

Optionally, the time length of the second time domain resource is greater than one time slot.

It is to be understood that, when the time length of the second time domain resource is greater than one time slot, then the terminal device is determining that the second power control adjustment state variable is equal to the first power control state variable. The second power correction value is not used at this time. In this case, the terminal device does not determine the second power control adjustment state variable by using the second power control adjustment state variable prepared for determining the second power correction value, but makes the second power control adjustment state variable equal to the first power control adjustment state variable, so that it is possible to prevent the second power correction value from making the power of the terminal device for transmitting the second channel larger or smaller, and it is possible to make the determined second power control adjustment state variable more adaptive to the current channel environment because the first power control adjustment state variable is the power control adjustment state variable determined according to the latest power correction value transmitted by the network device.

Optionally, when the time length of the second time domain resource is less than or equal to one time slot, the terminal device determines a second power control adjustment state variable using the second power correction value. This is because when the time length of the second time domain resource is less than or equal to one timeslot, the first time domain resource and the second time domain resource are both sTTI, and the round-trip time difference between them is small, so the power correction value sent by the network device does not cause the power of the second channel to be larger or smaller, and therefore the scheme in the prior art can be used to calculate the second power control adjustment state variable.

The terminal device determines a second power control adjustment state variable by using the second power correction value, and specifically, uses the sum of the first power control adjustment state variable and the second power correction value as the second power control adjustment state variable.
