Description

Communication method and device, computer readable storage medium and terminal

Technical Field

The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus, a computer readable storage medium, and a terminal.

Background

With the development of wireless communication technology, different network systems may coexist. For example, according to the present third generation partnership project (Third Generation Partnership Project, 3 GPP) for discussion of the Rel-18 side uplink (SL), it can be determined that a New air interface (New Radio, NR) system internet of vehicles (V2X) will perform enhanced research on coexistence of long term evolution (long term evolution, LTE) network system and NR network system in Rel-18, mainly involving co-channel coexistence (co-channel coexistence).

Dynamic resource sharing schemes have been extensively analyzed and studied for co-channel coexistence. In the dynamic resource sharing scheme, overlapping resource pools are configured for links of different network systems, and in this case, a problem of failure in receiving data transmitted by adopting a certain network system may occur. For example, the dynamic resource sharing scheme configures completely overlapping or partially overlapping resource pools for the sidelink and the sidelink of LTE, and supports operation in a scenario where overlapping (overlapping) resource pools exist by enhancing NR SIDELINK protocols. When the sidelink of LTE and the sidelink of NR use overlapping resource pools, a problem may occur in that LTE SIDELINK data cannot be effectively received.

Detailed Description

Communication systems to which embodiments of the present application are applicable include, but are not limited to, third generation systems (3 th-generation, 3G for short), LTE systems, fourth generation systems (4 th-generation, 4G for short), fifth generation (5 th-generation, 5G for short), NR systems, and future evolution systems or multiple communication fusion systems. The 5G system may be a non-independent Networking (NSA) 5G system or an independent networking (standalone, SA) 5G system. The scheme of the embodiment of the application can be also applied to various new communication systems in the future, such as 6G, 7G and the like.

The present application relates generally to communication between terminals, where different terminals may communicate via SL, e.g., a transmitting terminal may transmit data to a receiving terminal via SL. These terminals may also communicate with the network device over the air, e.g., the network device may configure the terminals with certain information.

A terminal in an embodiment of the present application may refer to various forms of User Equipment (UE), an access terminal, a subscriber unit, a subscriber Station, a Mobile Station (MS), a remote Station, a remote terminal, a Mobile device, a User terminal, a terminal device (Terminal Equipment), a wireless communication device, a User agent, or a User Equipment. The terminal may also be a cellular phone, a cordless phone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device, a terminal in a future 5G network or a terminal in a future evolved public land mobile network (Public Land Mobile Network, PLMN) and so on, which the embodiments of the present application are not limited.

The network device in the embodiment of the present application may also be referred to as an access network device, for example, may be a Base Station (BS) (also referred to as a base station device), and the network device is a device disposed in a radio access network (Radio Access Network, RAN) to provide a wireless communication function. For example, the device for providing a base station function in the second generation (2 nd-generation, abbreviated as 2G) network includes a base radio transceiver station (base transceiver station, abbreviated as BTS), the device for providing a base station function in the 3G network includes a Node B (Node B), the device for providing a base station function in the 4G network includes an evolved Node B (eNB), the device for providing a base station function in the wireless local area network (wireless local area networks, abbreviated as WLAN) is an Access Point (AP), the next generation base station Node (next generation Node base station, abbreviated as gNB) in the NR, and a Node B (ng-eNB) that continues to evolve, wherein the gNB and the terminal communicate using NR technology, the ng-eNB and the terminal communicate using evolved universal terrestrial radio access (Evolved Universal Terrestrial Radio Access, abbreviated as E-UTRA) technology, and the gNB and the ng-eNB can be connected to the 5G core network. The network device in the embodiment of the present application further includes a device for providing a base station function in a new communication system in the future, and the like.

As an example, the communication method provided in the embodiment of the present application may be applied in the technical field of Vehicle-to-evaluation (V2X). Referring to fig. 1, fig. 1 is a schematic diagram of an application scenario of a communication method according to an embodiment of the present application. As shown in fig. 1, terminal 1 may transmit data to terminal 2 through SL, terminal 1 being a transmitting device, and terminal 2 being a receiving device. The terminal 1 may send data to the terminal 2 using the scheme provided by the embodiment of the present application.

It should be noted that the solution of the embodiment of the present application may also be applied to other scenarios other than NR V2X, such as Device-to-Device (D2D), cellular network, relay network, etc.

As described in the background, in the co-channel coexistence scenario, a problem of failure in data reception using a certain network system transmission may occur. The present disclosure mainly describes a scenario in which an LTE network system and an NR network system coexist on SL as an example. In other examples, the uplink may be a scene where the LTE network system and the NR network system coexist, the downlink may be a scene where the LTE network system and the NR network system coexist, or a scene where other network systems other than the LTE network system or the NR network system coexist on the SL.

The automatic gain control (Automatic Gain Control, abbreviated AGC) problem is an urgent problem to be solved in the dynamic resource selection technical scheme. Specifically, AGC may refer to that when a receiving device receives SL transmission, the receiving device receives in-band spurious (in-band emissions) interference on a transmission symbol, and the receiving device adjusts an Analog-to-Digital (ADC) range according to the in-band spurious received on a certain symbol, so as to ensure that a received signal can be in a proper quantization interval, and correctly receive data of SL transmission. For LTE SL transmission, when different symbols are subjected to different in-band spurious interferences, AGC adjustment can only be performed according to the 1 st symbol in each subframe, if the in-band spurious interferences suffered by the subsequent symbols are too high, the receiving power of the receiving device of LTE may be out of the ADC range, which causes that the receiving device of LTE cannot decode the received data, and further causes data receiving failure.

Referring to fig. 2, fig. 2 is a schematic diagram of the overlapping of the resource pool of LTE SL and the resource pool of NR SL.

In the dynamic resource sharing technology, the SL of NR needs to support different subcarrier spacings (sub-CARRIER SPACING, abbreviated as SCS), such as 15Khz, 30Khz, 60Khz, etc. Whereas in LTE only a sub-carrier spacing of 15Khz is currently supported. If the subcarrier spacing of LTE SL and NR SL is different, the length of the time domain granularity (e.g., subframe) of LTE and the length of the time domain granularity (e.g., slot) of NR are different. When the SCS of the NR SL configuration is larger than that of the LTE SL configuration and the LTE SL overlaps partially or fully with the resource pool of the NR SL, there may be LTE SL transmissions and multiple NR SL transmissions within the time frame of a single LTE subframe. Wherein there is typically a difference in transmit power at which different transmitting devices transmit data.

Fig. 1 exemplifies 15kHz for SCS configured for LTE SL and 30kHz for nr SL, in which case a single subframe corresponds to 2 slots (i.e., slot 1 and slot 2). Within the time frame of the subframe shown in fig. 1, there may be 1 LTE transmitting device and 2 NR transmitting devices transmitting data, one NR transmitting device transmitting data in slot 1 and the other NR transmitting device transmitting data in slot 2.

Referring to fig. 3, fig. 3 is a schematic diagram of a transmission power.

As described above, when the SCS of the NR SL configuration is larger than that of the LTE SL configuration, and the LTE SL overlaps partially or entirely with the resource pool of the NR SL, there may be LTE SL transmission and multiple NR SL transmissions within the time frame of a single LTE subframe. Continuing with the example of fig. 2, a single subframe corresponds to 2 slots, assuming that there are 1 LTE transmitting device and 2 NR transmitting devices transmitting data in the time frame of the subframe. This LTE transmitting device is denoted LTE Tx in fig. 3, and 2 NR transmitting devices are denoted NR Tx1 and NR Tx2, respectively. Wherein, NR Tx1 and NR Tx2 transmit data on slot 1 and slot 2, respectively, with different transmit powers.

Since the LTE receiving apparatus (denoted as LTE Rx in fig. 3) can only perform AGC adjustment according to the 1 st symbol when receiving the data in the subframe shown in fig. 2, if the transmission power of NR Tx2 used in the slot 2 is too high, the interference of the in-band spurious received by the LTE receiving apparatus on the symbol corresponding to the slot 2 may be too high, which may cause that the reception power of LTE Rx is out of the ADC range, and LTE Rx cannot decode the received data, thereby causing failure of LTE Rx to receive the data.

For the above-described problems, it is possible to solve the problems by limiting that data can be transmitted only by the same NR transmitting apparatus on a plurality of slots corresponding to the same subframe. The NR transmitting device may transmit the same data on a plurality of slots corresponding to a single subframe, or may transmit the same or different data at a closer transmission power.

If the same data is transmitted in a plurality of time slots, the resource waste is obviously caused, and the feasibility is poor. If different data are transmitted, according to the existing NR SL power control scheme, a problem that transmission power of the different data has a large difference may still occur, and it cannot be guaranteed that the AGC problem of the LTE receiving device is avoided when the LTE SL and NR SL dynamic resources are shared.

In addition, if the transmission power adopted by the NR Tx is too low, the reception power of the LTE reception apparatus is out of the ADC range, and the received data cannot be decoded, which results in data reception failure.

In view of this, an embodiment of the present application provides a communication method, in an embodiment of the present application, data is sent on N consecutive first time units, where N is a positive integer greater than 1; the first transmitting power of the nth transmission data is smaller than or equal to a first threshold value corresponding to the nth first time unit, and/or the first transmitting power of the nth transmission data is larger than or equal to a second threshold value corresponding to the nth first time unit, the first threshold value corresponding to the nth first time unit is larger than or equal to a second threshold value corresponding to the nth first time unit, the nth transmission data is data transmitted in the nth first time unit, the nth first time unit is the nth first time unit in the nth first time unit, the first transmitting power of the nth transmission data is the transmitting power adopted when the nth transmission data is transmitted in the nth first time unit, and N is an integer which is more than or equal to 2.

Among the above schemes, a scheme is considered that supports the same transmitting apparatus (e.g., NR transmitting apparatus) to transmit different data on consecutive time units. Under the scheme, by increasing the upper limit constraint of the sending power (that is, the first sending power of the nth transmission data is smaller than or equal to the first threshold corresponding to the nth first time unit), the sending device can ensure that the power of the sending device for sending the data on each first time unit does not exceed the first threshold, so that the problem that the receiving power of the receiving device under different network systems is out of the ADC range and cannot be decoded due to the fact that the sending power is too high can be avoided, and the success rate of data receiving can be improved. Or under the scheme, by increasing the lower limit constraint of the sending power (that is, the first sending power of the nth transmission data is larger than or equal to the second threshold corresponding to the nth first time unit), the sending device can ensure that the power of the sending device for sending the data on each first time unit is not lower than the second threshold, so that the problem that the receiving device under different network systems cannot decode due to the too low sending power is effectively prevented, and the success rate of data receiving is improved. Or in this scheme, by increasing the upper and lower limit constraint of the transmission power, that is, the first transmission power of the nth transmission data is smaller than or equal to the first threshold corresponding to the nth first time unit and greater than or equal to the second threshold corresponding to the nth first time unit, it is ensured that the power of the transmission device for transmitting the data on each first time unit does not exceed the power range defined by the first threshold and the second threshold, so that the problem that the receiving device cannot decode when the transmission power is too high and too low can be avoided, and the success rate of data reception is improved.

For ease of understanding, some of the concepts mentioned below will first be clarified. In side-uplink communications, the terminal supports a perceptually based resource allocation pattern (which may also be referred to as a pattern 2 resource allocation pattern). In the resource allocation mode, the terminal autonomously selects resources for transmission from a resource pool configured for the terminal when transmission is required. When the resource selection process is triggered, the physical layer of the terminal judges the resource occupation condition in a period of time (called a resource selection window) in the future according to the perception result in the previous period of time (called a resource perception window), eliminates the unavailable resources in the resource selection window, finally forms a candidate resource set and reports the candidate resource set to a media access control (medium access control, called an MAC for short) layer, and the MAC layer selects transmission resources in the candidate resource set according to the resource selection constraint condition and performs data transmission according to the selected transmission resources.

Illustratively, the transmission resources selected for data 1, data 2, data 3, and data 4 in the resource selection process may be resource 1, resource 2, resource 3, and resource 4. That is, resource 1, resource 2, resource 3, and resource 4 determined by performing resource selection are used to transmit data 1, data 2, data 3, and data 4, respectively. However, in the actual transmission process, whether a data is transmitted using the resource determined for the data in the resource selection process is also affected by other factors, for example, the data 1, the data 2, and the data 4 may be actually transmitted on the resource 1, the resource 2, the resource 3, and the resource 4. Where each resource may be a time unit in the time domain.

Based on the above understanding, the meaning of the description of the present application section is as follows:

1. Nth first time unit: refers to the nth first time unit of the consecutive N (N is a positive integer greater than 1) first time units referred to hereinafter in the present application. Similarly, the N-1 th first time unit refers to the N-1 th first time unit of the consecutive N first time units. Wherein N is more than or equal to 2 and less than or equal to N, and N is an integer. Similarly, the kth first time unit refers to the kth first time unit of the consecutive N first time units. Wherein k is more than or equal to 1 and less than or equal to n-1, and k is an integer. Similarly, the first time unit refers to the first time unit of the N consecutive first time units. Wherein l is more than or equal to 1 and less than or equal to n-1, and l is an integer.

2. N-1 first time units: refers to the 2 nd to the nth first time units of the N first time units.

3. Nth transmission data: refers to data transmitted on the nth first time unit. In other words, the nth transmission data is data actually transmitted at the nth first time unit. Similarly, the n-1 th transmission data refers to data actually transmitted at the n-1 th first time unit.

4. Nth data: refers to data transmitted on the nth first time unit determined by the resource selection. The nth data may or may not be nth transmission data. Similarly, the (n-1) th data refers to data transmitted on the (n-1) th first time unit determined by the resource selection. Similarly, the kth data refers to data transmitted on the kth first time unit determined by the resource selection.

5. First transmission power: refers to the power used by the transmitting device when transmitting data. That is, the first transmission power refers to the actual transmission power of the data. Then, the first transmission power of the nth transmission data is a transmission power employed when the nth transmission data is transmitted on the nth first time unit. Similarly, the first transmission power of the n-1 th transmission data is a transmission power used when the n-1 th transmission data is transmitted on the n-1 th first time unit. Similarly, the first transmission power of the kth data is the transmission power used to transmit the kth data, which may or may not be transmitted in the kth first time unit.

6. Second transmit power: refers to the transmission power estimated by the transmitting device for data. That is, the transmitting apparatus estimates the power required to transmit data. Then, the second transmission power of the nth data is the estimated transmission power for the nth data. Similarly, the second transmit power of the n-1 th data is the transmit power estimated for the n-1 th data.

Wherein the transmitting device may determine the second transmit power of the data based on at least one of: maximum transmission power allowed by the transmitting device, path loss estimated by the transmitting device, a compensation factor of the path loss, the number of physical resource blocks (Physical Resource Block, abbreviated PRBs) occupied by transmitting nth data, and the like. The method for calculating the second transmission power of the data may refer to the related description of the existing protocol (such as the protocol TS38.213 sec.16.2 section), which is not described herein.

The unit of transmit power in embodiments of the present application may be decibel milliwatts (dBm). The data in the embodiment of the present application may be a Transport Block (TB) or other data, which is not limited by the present application. Transmission in the present application refers to sending and/or receiving.

Referring to fig. 4, fig. 4 is a flow chart of a communication method according to an embodiment of the application. The communication method shown in fig. 4 may include S41. In the present application, S in each step number represents a step (step).

And S41, the transmitting equipment transmits data on N continuous first time units, wherein the first transmitting power of the nth transmission data is smaller than or equal to a first threshold value corresponding to the nth first time unit, and/or the first transmitting power of the nth transmission data is larger than or equal to a second threshold value corresponding to the nth first time unit, and the first threshold value corresponding to the nth first time unit is larger than or equal to a second threshold value corresponding to the nth first time unit. Accordingly, the receiving device receives data over N consecutive first time units.

The method of the present application may be performed by a transmitting device or may be a module (such as a chip, a chip module, etc.) inside the transmitting device, and for convenience of description, the present application is exemplified by taking an execution body as the transmitting device. The transmitting device may be a transmitting terminal by way of example. The receiving device may be, for example, a receiving terminal.

In the scheme of the embodiment of the application, the N first time units correspond to the same second time unit in the time domain, and the first time units and the second time units can be the time domain granularity of data transmission under different network systems. In other words, a single second time unit corresponds to N first time units. The first time unit is the time domain granularity of data transmission in a first network system, the second time unit is the time domain granularity of data transmission in a second network system, and the first network system is different from the second network system. The transmitting apparatus that performs S41 in this embodiment is the transmitting apparatus of the first network system. In a specific example, the first network system is an NR network system, and the second network system is an LTE network system.

It should be noted that the correspondence between time units in this embodiment may be understood as overlapping in the time domain. In other words, a single second time unit overlaps with consecutive N first time units.

The first time unit may be a slot and the second time unit may be a subframe. It should be noted that in other embodiments, the first time unit and the second time unit may be of other time domain granularity. For example, the first time unit may be a symbol, the second time unit may be a slot, etc., without limitation.

It should be noted that, in the solution of the embodiment of the present application, the first thresholds corresponding to different first time units may be the same or different, and/or the second thresholds corresponding to different first time units may be the same or different.

It should be noted that, the first threshold and/or the second threshold corresponding to the first time unit refer to a threshold for determining the first transmission power of the data transmitted on the first time unit, and do not necessarily represent that there is a correspondence between the first time unit and the first threshold and/or the second threshold. For example, if the first threshold value and/or the second threshold value are preset fixed values, there is no correspondence between the first time unit and the first threshold value and/or the second threshold value. At this time, S41 may be described as: and transmitting the data on the N continuous first time units, wherein the first transmission power of the nth transmission data is smaller than or equal to a first threshold value, and/or the first transmission power of the nth transmission data is larger than or equal to a second threshold value, and the first threshold value is larger than or equal to the second threshold value.

The first transmission power of the data transmitted on the 1 st first time unit of the N first time units may be the second transmission power of the data.

In the first embodiment, for the nth transmission data, the first transmission power of the nth transmission data may be determined based on the second transmission power of the nth data. Optionally, the nth transmission data is the nth data. Further, the first transmission power of the nth transmission data may be determined according to the second transmission power of the nth transmission data and the first threshold and/or the second threshold corresponding to the nth first time unit.

In other words, the transmitting device may determine the first transmission power of the nth transmission data according to the second transmission power of the nth data and the first threshold and/or the second threshold corresponding to the nth first time unit, and then transmit the nth transmission data at the first transmission power of the nth transmission data on the nth first time unit.

Specifically, if the second transmission power of the nth data is greater than or equal to the first threshold corresponding to the nth first time unit, the first transmission power of the nth transmission data is the first threshold corresponding to the nth first time unit. That is, the transmitting device may determine that the first transmission power of the nth transmission data is a first threshold corresponding to the nth first time unit.

And if the second transmission power of the nth data is smaller than or equal to the second threshold corresponding to the nth first time unit, the first transmission power of the nth transmission data is the second threshold corresponding to the nth first time unit. That is, the transmitting device may determine that the first transmission power of the nth transmission data is the second threshold corresponding to the nth first time unit.

And if the second transmission power of the nth data is smaller than the first threshold value corresponding to the nth first time unit and larger than the second threshold value corresponding to the nth first time unit, the first transmission power of the nth transmission data is the second transmission power of the nth data. That is, the transmitting device may determine the first transmission power of the nth transmission data as the second transmission power of the nth data.

That is, the first transmission power of the nth transmission data may be expressed by equation (1) or equation (2):

P ₁(n)＝min{P_up(n),max{P₂(n),P_low (n) }; (1)

Or P ₁(n)＝max{P_low(n),min{P₂(n),P_up (n) } (2)

Wherein, P ₁ (n) represents a first transmission power of the nth transmission data, P ₂ (n) represents a second transmission power of the nth transmission data, P _up (n) represents a first threshold corresponding to the nth first time unit, and P _low (n) represents a second threshold corresponding to the nth first time unit.

In the solution of the first embodiment, the data actually transmitted in each first time unit is data determined by selecting resources, and the second transmission power is modified according to the first threshold and/or the second threshold to obtain the first transmission power, and then the nth transmission data is sent in the nth first time unit at the first transmission power of the nth transmission data.

In a second embodiment, the nth transmission data is determined based on the second transmit power of the nth data. That is, which data is transmitted on the nth first time unit is determined according to the second transmission power of the nth data.

In the first example, if the second transmission power of the nth data is greater than the first threshold corresponding to the nth first time unit or less than the second threshold corresponding to the nth first time unit, the nth transmission data is the nth-1 data. Further, the first transmission power of the nth transmission data is the second transmission power of the n-1 st data. In other words, if the second transmission power of the nth data is greater than the first threshold corresponding to the nth first time unit or less than the second threshold corresponding to the nth first time unit, the transmitting device may transmit the nth-1 data at the second transmission power of the nth-1 data over the nth first time unit.

If the second transmission power of the nth data is smaller than or equal to the first threshold corresponding to the nth first time unit and is larger than or equal to the second threshold corresponding to the nth first time unit, the nth transmission data is the nth data. The first transmission power of the nth transmission data is the second transmission power of the nth transmission data. In other words, if the second transmission power of the nth data is less than or equal to the first threshold corresponding to the nth first time unit and greater than or equal to the second threshold corresponding to the nth first time unit, the transmitting device may transmit the nth data at the second transmission power of the nth data over the nth first time unit.

In a second example, the nth transmission data is the nth-1 transmission data if the second transmission power of the nth data is greater than the first threshold corresponding to the nth first time unit or less than the second threshold corresponding to the nth first time unit.

Further, the first transmission power of the nth transmission data is the first transmission power of the n-1 th transmission data. That is, if the second transmission power of the nth data is greater than the first threshold corresponding to the nth first time unit or less than the second threshold corresponding to the nth first time unit, the transmission power used by the transmitting device for transmitting the data in the nth first time unit is the same as the transmission power used for transmitting the data in the previous first time unit. In other words, the transmitting device may transmit the n-1 th transmission data at the first transmission power of the n-1 th transmission data on the n-th first time unit. That is, the transmitting apparatus repeatedly transmits the n-1 th transmission data at the same transmission power on the n-th first time unit.

If the second transmission power of the nth data is smaller than or equal to the first threshold corresponding to the nth first time unit and is larger than or equal to the second threshold corresponding to the nth first time unit, the nth transmission data is the nth data, and the first transmission power of the nth transmission data is the second transmission power of the nth data. That is, if the second transmission power of the nth data is less than or equal to the first threshold corresponding to the nth first time unit and greater than or equal to the second threshold corresponding to the nth first time unit, the transmitting apparatus may transmit the nth data at the second transmission power of the nth data over the nth first time unit.

When the scheme of the second embodiment is adopted, for the data which is determined through resource selection and cannot be transmitted, the transmitting terminal can trigger resource reselection and adopts the resource after reselection to transmit.

The values of the first threshold and the second threshold are described below without limitation.

In a first example, the first threshold value and/or the second threshold value is a preset value.

For example (denoted as example 1), the first threshold and/or the second threshold may be specified by a protocol.

As another example (denoted as example 2), the first threshold and/or the second threshold may be preconfigured by higher layer signaling.

In case one of example 2: the first threshold and/or the second threshold may be configured by a network device accessed by the transmitting device via radio resource control (Radio Resource Control, abbreviated RRC) signaling. The transmitting device may directly pre-configure the first threshold and/or the second threshold using RRC signaling when there is a need to transmit data.

In case two of example 2: the network device accessed by the sending device may configure a threshold set for the sending device through RRC signaling, where the threshold set may include a plurality of selectable thresholds. The transmitting device can select a first threshold value and a second threshold value from the threshold value set when the transmitting device has a data transmission requirement; or the network device may indicate the adopted first threshold and the second threshold to the transmitting device through downlink control information (Downlink Control Information, abbreviated as DCI). The threshold set may be a threshold set from which the first threshold and the second threshold are selected, or one threshold set may be configured for the first threshold to select the first threshold, and another threshold set may be configured for the second threshold to select the second threshold.

In a second example, the first threshold corresponding to the nth first time unit and/or the second threshold corresponding to the nth first time unit may be determined according to the first transmission power of the kth data.

The value of k may be the same or different for different first time units of the N-1 first time units.

As a non-limiting example, k is a fixed value, i.e. the value of k may be the same for N-1 first time units. In implementations, the value of k may be specified by the protocol or may be pre-configured by higher layer signaling.

For example, k=1, the first threshold corresponding to the nth first time unit and/or the second threshold corresponding to the nth first time unit are determined according to the first transmission power of the 1 st data.

As another non-limiting example, k is an iteration value associated with n. For example, k=n-1. That is, the first threshold corresponding to the nth first time unit and/or the second threshold corresponding to the nth first time unit are/is determined according to the first transmission power of the (n-1) th data.

Further, the first threshold corresponding to the nth first time unit may be determined using equation (3):

P _up(n)＝P₁(k)+ΔP_up type (3)

Wherein, P _up (n) is a first threshold corresponding to the nth first time unit, P ₁ (k) is a first transmission power of the kth data, and Δp _up is a first reference power value. Wherein Δp _up may be a preset value. In implementations, Δp _up may be predefined by the protocol or may be preconfigured by higher layer signaling.

The second threshold corresponding to the nth first time unit may be determined using equation (4):

p _low(n)＝P₁(k)-ΔP_low (4)

Wherein, P _low (n) is a second threshold corresponding to the nth first time unit, P ₁ (k) is a first transmission power of the kth data, and Δp _low is a second reference power value. Wherein Δp _low may be a preset value. In implementations, Δp _low may be predefined by the protocol or may be preconfigured by higher layer signaling.

In implementations, Δp _low and Δp _up are both non-negative numbers. Typically, Δp _low and/or Δp _up are greater than 0.Δp _low and Δp _up may also both be 0, in which case P _up(n)＝P_low(n)＝P₁ (k).

Substituting the formula (3) and the formula (4) into the formula (1) can obtain the formula (6):

P ₁(n)＝min{P₁(k)+ΔP_up,max{P₂(n),P₁(k)-ΔP_low } (5)

Or formula (11) can be obtained by substituting formula (3) and formula (4) into formula (2):

p ₁(n)＝max{P₁(k)-ΔP_low,min{P₂(n),P₁(k)+ΔP_up } (6)

From the above, the transmitting apparatus may determine the first transmission power of the nth transmission data according to equation (5) or equation (6).

In a third example, the first threshold of the nth first time unit and/or the second threshold corresponding to the nth first time unit may be determined according to the first transmission power employed in the first time unit. The first transmission power adopted by the first time unit refers to the first transmission power of the data sent by the sending device on the first time unit. In other words, the first transmission power used by the first time unit is the first transmission power of the first transmission data.

The values of l may be the same or different for different ones of the N-1 first time units.

As a non-limiting example, l is a fixed value, i.e. for N-1 first time units, the value of l may be the same. In implementations, the value of l may be specified by the protocol or may be pre-configured by higher layer signaling.

For example, l=1, the first threshold corresponding to the nth first time unit and/or the second threshold corresponding to the nth first time unit are determined according to the first transmission power corresponding to the 1 st first time unit. In other words, the first threshold corresponding to the nth first time unit and/or the second threshold corresponding to the nth first time unit are determined according to the first transmission power of the 1 st transmission data. As an example, the 1 st transmission data may be the 1 st data determined by the resource selection, and the first transmission power employed by the 1 st first time unit may be the second transmission power of the 1 st data.

As another non-limiting example, l is an iteration value associated with n. For example, l=n-1. That is, the first threshold corresponding to the nth first time unit and/or the second threshold corresponding to the nth first time unit are determined according to the first transmission power adopted in the (n-1) th first time unit. In other words, the first threshold and/or the second threshold corresponding to the nth first time unit are determined according to the first transmission power of the data transmitted by the previous first time unit. That is, the first threshold and/or the second threshold corresponding to the nth first time unit are determined according to the first transmission power of the n-1 th transmission data.

Further, the first threshold corresponding to the nth first time unit may be determined using equation (7), and the second threshold corresponding to the nth first time unit may be determined using equation (8):

P _up(n)＝P₁(l)+ΔP_up (7)

P _low(n)＝P₁(l)-ΔP_low type (8)

Wherein, P _up (n) is a first threshold corresponding to the nth first time unit, P _low (n) is a second threshold corresponding to the nth first time unit, P ₁ (l) is a first transmission power corresponding to the first time unit, Δp _up is a first reference power value, and Δp _low is a second reference power value. P _up(n)＝P_low(n)＝P₁ (l) when Δp _low＝0,ΔP_up =0. For more details regarding Δp _up and Δp _low, reference is made to the relevant description above and will not be repeated here.

Wherein Δp _low and/or Δp _up may be preset values. In implementations, Δp _low and/or Δp _up may be predefined by the protocol or may be preconfigured by higher layer signaling. Δp _low and Δp _up are both non-negative numbers. Typically, Δp _low and/or Δp _up are greater than 0.Δp _low and Δp _up may both be 0, in which case P _up(n)＝P_low(n)＝P₁ (l).

Substituting formula (7) and formula (8) into formula (1) can give formula (9):

P ₁(n)＝min{P₁(l)+ΔP_up,max{P₂(n),P₁(l)-ΔP_low } (9)

Or formula (7) and formula (8) are substituted into formula (2) to obtain formula (10):

P ₁(n)＝max{P₁(l)-ΔP_low,min{P₂(n),P₁(l)+ΔP_up } (10)

From the above, the transmitting apparatus can determine the first transmission power of the nth transmission data according to equation (9) or equation (10).

From the above, for the NR terminal or chip module supporting the co-channel coexistence dynamic resource sharing of Rel-18SL, in order to avoid the AGC problem caused by the NR SL using different subcarrier spacing from the LTE SL, the scheme supporting the same NR terminal or chip module to transmit different data on a plurality of consecutive time slots is considered in the scheme of the embodiment of the present application. Under the scheme, the problem of AGC of the LTE receiving equipment can be avoided as much as possible by increasing the upper limit constraint and the lower limit constraint of the actual transmission power of a certain transmission block.

In other embodiments, the value of N may be 1. In other words, the first time unit and the second time unit may be in a one-to-one correspondence. For example, when SCS of LTE and SCS of NR are the same, n=1. In this case, the transmitting device may also determine the data to be transmitted and its second transmission power through resource selection, and then compare the second transmission power of the data with the first threshold and the second threshold, and if the second transmission power of the data is smaller than the first threshold and larger than the second threshold, the transmitting device may transmit the data at the second transmission power of the data. The transmitting device may transmit the data with the first threshold as the first transmit power if the second transmit power of the data is greater than or equal to the first threshold. The transmitting device may transmit the data with the second threshold as the first transmit power if the second transmit power of the data is less than or equal to the second threshold.
