Description

Uplink guaranteed power information sending and receiving method and equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and apparatus for transmitting and receiving uplink guaranteed power information.

Background

In a long term evolution (Long term evolution, LTE) system, a terminal device supports simultaneous access to two network devices, in a manner called dual connectivity (Dual Connectivity, DC), where one network device is a primary network device and the other network device is a secondary network device, where one or more cells served by the primary network device to the terminal device are called a primary cell group (Master Cell Group, MCG), and one or more cells served by the secondary network device to the terminal device are called a secondary cell group (Secondary Cell Group, SCG). In the evolution and development process of the wireless communication system, an operator deploys a 5G new air interface (New radio interface, NR) system and a long term evolution (Long term evolution, LTE) system simultaneously, and a terminal device also supports network devices that access LTE and NR simultaneously, and because LTE is also called evolved universal terrestrial radio access (Evolved Universal Terrestrial Radio Access, E-UTRA), this access mode is called evolved universal terrestrial radio access and new air interface dual connection (E-UTRA NR Dual Connectivity, EN-DC). In EN-DC mode, the network device of LTE is a primary network device, the network device of NR is a secondary network device, and of course, along with the evolution of the system, a new air interface and evolved universal terrestrial radio access dual connection (NR E-UTRA Dual Connectivity, NE-DC) may also be supported in the future, i.e. the network device of NR is a primary network device, and the network device of LTE is a secondary network device. Since both EN-DC and NE-DC terminals will access network devices of two different radio access technologies, these DC modes may also be collectively referred to as Multi-radio access technology dual connectivity (Multi-RAT Dual Connectivity, MR-DC). In addition, for terminal devices that support only NR, they can also access two different NR network devices at the same time, such a connection being called NR-nrdc.

The wireless communication system can be divided into a frequency division duplex (Frequency Division Duplex, FDD) mode and a time division duplex (Time Division Duplex, TDD) mode according to the difference of duplex modes, wherein the system usually only comprises one operating frequency band for the wireless communication system operating in TDD mode, so the frequency band is also called unpaired frequency band. For a system using unpaired frequency bands, in a period of time, the whole working frequency band is only used for downlink communication or only used for uplink communication in an area covered by the same network equipment; for wireless communication systems operating in FDD mode, the system typically includes two paired frequency bands for communication, one for network device to terminal device downstream communication and the other for terminal device to network device upstream communication.

Currently, a typical deployment is where NR deploys in a TDD mode on unpaired frequency bands, such as frequency bands around 3.5 GHz. In this deployment scenario, the cells in both the MCG and SCG of the terminal device operating in NR-NR DC mode are in TDD mode.

In order to increase the rate of the terminal device sending uplink signals to the network device, the terminal device usually operating in the DC mode may send uplink signals to the network device on carriers in the MCG and SCG simultaneously in the same time period, but the total power of the terminal device sending uplink signals on all carriers is often limited, for example, the total power of the terminal device sending uplink signals on carriers in the MCG and SCG cannot exceed 23dBm at maximum, so if the total power of the terminal device sending uplink signals on carriers in the MCG and SCG exceeds the maximum sending power, the terminal needs to actively reduce the sending power on one or more carriers. The specific implementation mode is as follows:

The network device configures the minimum guaranteed power of each Cell Group (CG) for the terminal device, and one CG can preferentially use the minimum guaranteed power configured by the network device for the network device; and when the minimum guaranteed power is not used by the CG, the remaining power may be used by another CG. For example, for a given two CGs, including CG1 and CG2, the network device configures CG1 with parameter r1=0.2, and the terminal device determines that the guaranteed power of CG1 is 20% of the total power, and this portion of power terminal is preferentially used for CG1; configuring CG2 with parameter r2=0.3, the guaranteed power of CG2 is determined to be 30% of the total power, and this part of power terminals is preferentially used for CG2. So that for the power remaining after removal of the guaranteed power of CG1 and CG2 (50% of the total power), the terminal may determine the allocation of power based on the signal priority or CG priority as described above.

However, the configuration of guaranteed power of the prior art CG is not flexible enough.

Disclosure of Invention

The embodiment of the application provides a method and equipment for transmitting and receiving uplink guaranteed power information, which are used for solving the problem that the guaranteed power of CG in the prior art cannot be flexible.

In a first aspect, an embodiment of the present application provides a method for sending uplink guaranteed power information, where the method includes:

Determining a first minimum guaranteed power group for transmitting uplink signals in a first cell group, wherein the first minimum guaranteed power group comprises N minimum guaranteed powers, the N minimum guaranteed powers are in one-to-one correspondence to N time periods, the N time periods are time periods included in one radio frame, and N is a positive integer not less than 2;

and sending first indication information to the terminal equipment, wherein the first indication information is used for indicating the N minimum guaranteed powers.

In a second aspect, there is provided a method for receiving uplink guaranteed power information, the method including:

and the terminal equipment configures the minimum guaranteed power for transmitting the uplink signal in the first cell group according to the first indication information.

The above method can be applied to a dual connectivity scenario.

In this implementation manner, for the terminal device operating in the DC mode, the network device may determine a minimum power guarantee group corresponding to a time period in the radio frame, where the minimum power guarantee group includes minimum power guarantees corresponding to at least two time periods, and values in the minimum power guarantee group may be the same or different, and the number of the minimum power guarantee groups may also be set according to a specific situation.

In an implementation manner, the first indication information includes N indication fields, where the N fields are in one-to-one correspondence with the N minimum guaranteed powers, and the minimum guaranteed power indicated by each of the N fields is the minimum guaranteed power for transmitting the uplink signal in the first cell group in the corresponding time period.

In this implementation, the first indication information may include a field indicating each time period, so that the minimum guaranteed power of all the time periods can be indicated to the terminal device through one piece of information. Of course, the values of the fields in the first indication information may not be in one-to-one correspondence with the time periods, for example: the minimum guaranteed power for all time periods may then comprise only one field.

In an implementation manner, the first indication information further indicates whether N minimum guaranteed powers in the first minimum guaranteed power group can be used to send uplink signals in a second cell group.

In this implementation manner, the first indication information may be divided into two parts, where the two parts of information indicate, in addition to the minimum guaranteed power of the multiple time periods, whether the minimum guaranteed power of the first cell group in a certain time period can be used by other cell groups, which enables the minimum guaranteed power of the different time periods to be flexibly configured to be used by other cell groups or not to be used by other cell groups, so that when the minimum guaranteed power can be used by other cell groups, the guaranteed power is prevented from being wasted, and when the minimum guaranteed power cannot be used by other cell groups, the maximum power of the other cell groups can be limited, so that interference on uplink signals of the first cell group is reduced, and in this way, flexibility of uplink power allocation of the terminal device is further improved.

In an implementation manner, the first indication information further indicates a second minimum guaranteed power group, the second minimum guaranteed power group includes N minimum guaranteed powers, the N minimum guaranteed powers in the second minimum guaranteed power group correspond to the N time periods one by one, the N minimum guaranteed powers in the second minimum guaranteed power group are only used for transmitting uplink signals in the first cell group, and the N minimum guaranteed powers in the first minimum guaranteed power group can be used for transmitting uplink signals in the second cell group.

In this implementation manner, the first indication information may be divided into two parts, where the two parts of information respectively indicate the minimum guaranteed power that can be used by other cell groups and the minimum guaranteed power that cannot be used by other cell groups, which correspond to the multiple time periods, so that the minimum guaranteed power in multiple different sharing manners is provided for the terminal device, flexibility of uplink power allocation of the terminal device is improved, and the implementation manner can be referred to above.

In an implementation manner, the first indication information further indicates a third minimum guaranteed power group, where the third minimum guaranteed power group includes N minimum guaranteed powers, the N minimum guaranteed powers in the third minimum guaranteed power group are in one-to-one correspondence with the N time periods, the N minimum guaranteed powers in the third minimum guaranteed power group are used to send the second type uplink signal in the first cell group, and the N minimum guaranteed powers in the first minimum guaranteed power group are used to send the first type uplink signal in the first cell group.

In an implementation manner, the first type of uplink signal includes a physical uplink control channel PUCCH carrying ACK/NACK, and the second type of uplink signal includes a physical uplink shared channel PUSCH carrying URLLC service.

In the implementation manner, the network device configures different minimum guaranteed powers for different uplink signals or different services of the terminal device, so that the network device and the terminal device can perform configuration of the minimum guaranteed powers after comprehensive consideration from different dimensions, and the requirements of different signals and services can be met under the condition that the minimum guaranteed power configuration mode is flexible in function, and the utilization rate of the uplink power can be effectively improved.

In an implementation manner, the first indication information includes N indication tuples, where the N indication tuples are in one-to-one correspondence with N time periods; each indication tuple comprises a first indication field n1 and a second indication field n2; wherein n1 and n2 correspond to the first minimum guaranteed power group and the third minimum guaranteed power group, respectively.

In this implementation manner, if the first indication information includes two parts, different parts in the first indication information are respectively indicated by different fields, so that different indication information can be more quickly and effectively transmitted to the terminal device.

In an implementation manner, the first cell group is one of a plurality of cell groups, and the method further includes:

The network device sends second indication information to the terminal device, wherein the second indication information indicates the priority of the plurality of cell groups for power distribution in the N time periods.

When the cell group comprises a plurality of cell groups, in the implementation manner, the network device can also send second indication information to the terminal device, and the second indication information can indicate the priority among different cell groups, so that the terminal device can perform power configuration of the cell group according to the priority.

In an implementation manner, the plurality of cell groups include the first cell group and the second cell group, the priority is used for the terminal device to simultaneously send uplink signals on the first cell group and the second cell group, if the total power of uplink signals on the first cell group and the second cell group exceeds the maximum sending power, then the sending power of uplink signals on the cell group with low priority is reduced according to the priority.

In one implementation, the first cell group is a primary cell group MCG and the second cell group is a secondary cell group SCG.

In the implementation mode, the method can realize that the priority of the SCG is higher than that of the MCG in a certain time period, and the problem that the performance of the SCG is influenced due to the unified priority used in the prior art is avoided.

In an implementation manner, the third indication information includes N indication fields, where the N fields are in one-to-one correspondence with N time periods; wherein each of the N fields is used to indicate a priority of the first cell group and the second cell group in a corresponding time period; n is a positive integer.

Through the implementation manner of the third aspect, when the cell group includes a plurality of cell groups, the network device may further send second indication information to the terminal device, where the second indication information may indicate priorities between different cell groups, so that the terminal device may perform power configuration of the cell group according to the priorities, and by using the method, it may ensure that power of the cell group with high priority is preferentially ensured under the condition that power limitation requirements are met, so that it is possible to reasonably configure power of different cell groups, and meanwhile, it may also flexibly adjust priorities corresponding to the cell groups according to conditions, so as to avoid the problem that in the prior art, performance of SCG is affected due to using uniform priorities.

Detailed Description

Before introducing the method provided by the embodiment of the present application, a simple description is first made of an applicable scenario in which the terminal device applicable to the embodiment of the present application operates in a dual-connection mode according to the scenarios shown in fig. 1-1, fig. 1-2, fig. 2-1 and fig. 2-2; the scenario shown in fig. 1-1 and fig. 1-2 below is the first scenario in which the primary network device and the secondary network device are deployed on the same site; the scenarios shown in fig. 2-1 and 2-2 are second scenarios in which the primary network device and the secondary network device are deployed on different sites. In the method provided by the embodiment of the application, the terminal equipment is simultaneously accessed to the main network equipment and the auxiliary network equipment, and the method is applicable to both the first middle scene and the second scene. In addition, the primary network device and the secondary network device may be network devices of the same radio access technology, such as NR or LTE, or may be network devices of different radio access technologies. Whether in the first scenario or the second scenario, the network element device according to the embodiment of the present application may include (the network element device provided herein is only an example, if participation of other network element devices is required according to a specific implementation scheme, the processing is performed according to a specific actual scheme, and the example provided herein does not limit the specific implementation of the scheme):

Terminal equipment: for transmitting an upstream signal to a network device or receiving a downstream signal from the network device; can be a mobile phone, a tablet computer, a virtual reality terminal device, an augmented reality terminal device, a wireless terminal in industrial control and the like.

Network equipment: for receiving an uplink signal from a terminal device or transmitting a downlink signal to the terminal device; the network device, which may be LTE and/or NR, may be a base station (NodeB), an evolved base station (eNodeB), a base station in a 5G mobile communication system, a next generation mobile communication base station (next generation Node B, gNB), a base station in a future mobile communication system or an access node in a Wi-Fi system, etc.

In the prior art, the guaranteed power of the CG can only be configured for the whole wireless frame, that is, the guaranteed power of the CG is equal in all time periods in one wireless frame, so that the guaranteed power of the CG cannot flexibly adapt to the requirements of different time periods.

With reference to the above application scenario and the specific description of the network element structure, the following describes the technical solution in the embodiment of the present application with reference to the drawings in the embodiment of the present application.

As shown in fig. 3, an embodiment of the present application provides a method for transmitting and receiving uplink guaranteed power, for convenience of understanding, in the following description, a method of an embodiment of the present application is specifically described in a manner of information interaction between a network device and a terminal device, but when specifically implemented, both the network device and the terminal device in the embodiment of the present application may be separately configured and then implement a scheme provided by the embodiment of the present application, and the specific method provided by the embodiment of the present application may include:

Step 301, a network device determines a first minimum guaranteed power group for transmitting an uplink signal in a first cell group, where the first minimum guaranteed power group includes N minimum guaranteed powers, the N minimum guaranteed powers are in one-to-one correspondence with N time periods, where the N time periods are time periods included in one radio frame, and N is a positive integer not less than 2;

in this embodiment, the time period may be a frame, a subframe, a time slot, a micro time slot, a symbol, or the like, or may be a combination of a plurality of frames, a combination of a plurality of time slots, or the like, which are set as needed, and in this embodiment, the scheme to be implemented is to configure the minimum guaranteed power uniformly set in the prior art in a more flexible manner, so only the time period in this example may be divided into finer granularity on the basis of the uniformity of the original time (i.e., N is a positive integer not less than 2 in comparison with the case of uniformity in the prior art), and is not particularly limited to a frame or a subframe, or the like. Further, the value of N may be a positive integer less than or equal to the number of time slots in a radio frame, where, taking a time slot as an example, N may be one of 10, 20, 40, 80, and 160, and taking a time slot as an example, n=10. The value of N may be a positive integer less than or equal to the number of uplink time periods in one radio frame, where the specific value of N is related to uplink and downlink time resource allocation of a cell in the first cell group.

Further, the minimum guaranteed power may also be referred to as the minimum power in this embodiment, or the guaranteed power, or other description, and the name is not limited in this disclosure. It should be appreciated that the minimum guaranteed power for the first cell group is the power that the first cell group can use preferentially, and this part of power is only possible for other cell groups to use if the first cell group is not in use. The minimum guaranteed power of the first cell group can be understood as only the power that can be used by the first cell group, after the power with the set value is allocated to the first cell group, the power that needs to be kept all the time is special for the first cell group, and under the condition that the first cell group cannot be used completely, the minimum guaranteed power quota of the first cell group cannot be reduced, and then other cell groups can be compensated. In addition, the power that can be used by the first cell group described herein is understood to be the power that the terminal device can use to transmit uplink signals in the first cell group.

Step 302, the network device sends first indication information to the terminal device, where the first indication information is used to indicate the N minimum guaranteed powers.

Step 303, the terminal device receives the first indication information; the first indication information is used for indicating N minimum guaranteed powers of a first minimum guaranteed power group; the first minimum guaranteed power group comprises N minimum guaranteed powers, the N minimum guaranteed powers are in one-to-one correspondence with N time periods, the N minimum guaranteed powers are the minimum guaranteed powers of the terminal equipment for transmitting uplink signals in the first cell group, the N time periods are time periods included in one radio frame, and N is a positive integer not less than 2;

Step 304, the terminal device configures the minimum guaranteed power of the uplink signal sent by the first cell group according to the first indication information.

In this embodiment, for a terminal device operating in the DC mode, the network device may determine a minimum power guarantee group corresponding to a time period, where the minimum power guarantee group includes minimum power guarantees corresponding to at least two time periods, and values in the minimum power guarantee group may be the same or different, and the number of the minimum power guarantee groups may be set according to a specific situation.

In this instance, the first indication information may indicate only one information related to the minimum guaranteed power, but may also indicate a plurality of information related to the minimum guaranteed power; the specific implementation manner of the indication information is described in further detail according to the content indicated by the first indication information:

first kind: the first indication information indicates that only one information related to the minimum guaranteed power is indicated, and specifically may be a value of the minimum guaranteed power of the cell group. In order to achieve the purpose that the first indication information indicates N minimum guaranteed powers corresponding to N time periods one by one, in this embodiment, the setting manner of the first indication information may be:

The first indication information comprises N indication fields, the N fields are in one-to-one correspondence with the N minimum guaranteed powers, and the minimum guaranteed power indicated by each of the N fields is the minimum guaranteed power for transmitting uplink signals in the first cell group in a corresponding time period.

For example, the first indication information includes N indication fields, and the nth indication field indicates the minimum guaranteed power of the first cell group in the nth time period of N time periods (the time period may be a slot in this example).

Specifically, the nth indication field includes a parameter Rn, where Rn is a real number between 0 and 1. For example, rn may take a value of 0.5, meaning that the minimum guaranteed power for the first cell group is 50% of the total power. Further alternatively, the value of Rn may be a special value X, and when Rn is taken as X, it indicates that all the power in the nth slot is not shared by the first cell group, and the power in the nth slot cannot be used by other cell groups. At this time, the terminal device cannot transmit the uplink signals of other cell groups in the nth time slot.

Taking n=10 as an example, the cell group with 15kHz subcarrier spacing may be correspondingly adopted, and the first indication information indicates 10 time slots in one frame, where the first indication information may be {0.1,0.1,0.2,0.2,0.4,0.4,0.1,0.1,0.2,0.2}, which indicates that the minimum guaranteed power in the first cell group in the 1 st, 2 nd, 7 th and 8 th time slots in one frame of the terminal device is 0.1×pmax, where Pmax may be the maximum transmission power of the terminal device, where Pmax may be a value configured by the network device for the terminal device, or may be a value predefined in a protocol. The minimum guaranteed power of the terminal device in the target cell group in the 3 rd, 4 th, 9 th and 10 th slots in one frame is 0.2×pmax, and the minimum guaranteed power in the first cell group in the 5 th and 6 th slots is 0.4×pmax.

The second, the first indication information indicates two information related to the minimum guaranteed power, specifically, in order to achieve the purpose that the first indication information indicates N minimum guaranteed powers corresponding to N time periods one by one, in this embodiment, the setting manner of the first indication information may be:

in the first mode, the first indication information further indicates whether N minimum guaranteed powers in the first minimum guaranteed power group can be used to send uplink signals in the second cell group.

In this implementation manner, the first indication information may be divided into two parts, where the two parts of information indicate, in addition to the minimum guaranteed power of the multiple time periods, whether the minimum guaranteed power of the first cell group in a certain time period can be used by other cell groups, so that the minimum guaranteed power of different time periods can be flexibly configured to be used by other cell groups or not used by other cell groups, and flexibility of uplink power allocation of the terminal device is improved.

The second mode and the first indication information also indicate a second minimum guaranteed power group, the second minimum guaranteed power group comprises N minimum guaranteed powers, the N minimum guaranteed powers in the second minimum guaranteed power group are in one-to-one correspondence with the N time periods, the N minimum guaranteed powers in the second minimum guaranteed power group are only used for transmitting uplink signals in the first cell group, and the N minimum guaranteed powers in the first minimum guaranteed power group can be used for transmitting uplink signals in the second cell group.

In this implementation manner, the first indication information may be divided into two parts, where the two parts of information respectively indicate minimum guaranteed power that can be used by other cell groups and minimum guaranteed power that cannot be used by other cell groups, which correspond to multiple time periods, so that minimum guaranteed powers in multiple different sharing manners are provided for the terminal device, and flexibility of uplink power allocation of the terminal device is improved.

The third mode, the first indication information further indicates a third minimum guaranteed power group, the third minimum guaranteed power group includes N minimum guaranteed powers, the N minimum guaranteed powers in the third minimum guaranteed power group are in one-to-one correspondence with the N time periods, the N minimum guaranteed powers in the third minimum guaranteed power group are used for sending the second type uplink signal in the first cell group, and the N minimum guaranteed powers in the first minimum guaranteed power group are used for sending the first type uplink signal in the first cell group.

In this embodiment, the first type uplink signal and the second type uplink signal are uplink signals having different types. For example, the traffic type of the first type of uplink signal is different from the traffic type of the second type of uplink signal, specifically, the traffic type of the second type of uplink signal is high reliability low latency communication (Ultra-Reliable Low Latency Communications, URLLC) traffic, and the traffic type of the first type of uplink signal is non-URLLC traffic, such as enhanced mobile broadband (enhanced Mobile Broadband, eMBB) traffic. Further, the first type of uplink signal may be a Physical-layer uplink control channel (PUCCH) including a Physical uplink control channel (ACK/NACK) carrying Acknowledgement/negative Acknowledgement (ACK/NACK), and the second type of uplink signal may be a Physical-layer uplink shared channel (PUSCH) including a Physical uplink shared channel (ullc) carrying URLLC traffic. The first type of uplink signal and the second type of uplink signal are only specific examples, and are not limited to the first type of uplink signal and the second type of uplink signal in the embodiment of the present application, but only the two specific signal types are provided. In addition, the first type uplink signal or the second type uplink signal may include a plurality of different types of uplink signals, respectively, for example, the first type uplink signal includes two types of uplink signals of PUCCH and physical random access channel (Physical Random Access Channel, PRACH) carrying ACK/NACK.

In the implementation manner, the network device configures different minimum guaranteed powers for different uplink signals or different services of the terminal device, so that the network device and the terminal device can configure the minimum guaranteed powers from different dimensions after comprehensive consideration, and the requirements of different signals and services can be met under the condition of flexibly configuring the minimum guaranteed powers, and the utilization rate of the uplink power can be effectively improved.

Since the first to third modes described above may indicate two pieces of information related to the minimum guaranteed power, the first indication information may be an indication tuple including an indication unit of a time period, and correspond to:

the first indication information may include N indication tuples, where the N indication tuples are in one-to-one correspondence with N time periods; each indication tuple comprises a first indication field n1 and a second indication field n2; wherein n1 and n2 correspond to the first minimum guaranteed power group and the third minimum guaranteed power group, respectively; alternatively, n1 and n2 correspond to a first minimum guaranteed power group and a second minimum guaranteed power group, respectively.

The following describes the schemes from the first mode to the third mode in a specific exemplary manner in combination with the indication tuple implementation manner of the first indication information, where in this example, the time period may be a time slot, and may specifically be:

For the first mode, the first indication information includes N indication tuples, and the nth indication tuple includes two indication fields, which are respectively denoted as indication field N1 and indication field N2, for example, "N1, N2". Specifically, the indication field N1 indicates the N minimum guaranteed powers; the indication field N2 indicates whether the N minimum guaranteed powers in the first minimum guaranteed power group can be used to send uplink signals in the second cell group, that is, whether the minimum guaranteed power corresponding to the first cell group indicated by N1 can be used to send uplink signals in the second cell group.

Specifically, the indication field n2 is a 1-bit field, where the value corresponding to the 1 bit may be 0 or 1, and when the value of the 1 bit is 0, it indicates that the minimum guaranteed power indicated by the indication field n1 cannot be used to send the uplink signal in the second cell group; when the value of 1 bit is 1, it indicates that the minimum guaranteed power indicated by the indication field n1 can be used to transmit an uplink signal in the second cell group. Describing n=10 as an example, a cell group employing a 15kHz subcarrier spacing may correspond.

For example: the first indication information may be { 0.1,0 }, "0.05, 0 }," 0.1,1, "0.4,1", "0.4,1", "0.3,1", "0.3,1" }. The specific meaning of the indication is: the minimum guaranteed power indicated by the first to fourth fields n1 to n1 can not be used to transmit an uplink signal at the second cell group, and the minimum guaranteed power indicated by the remaining field n1 can be used to transmit an uplink signal at the second cell group. Since field n1 corresponds to a slot, the minimum guaranteed power corresponding to the first through fourth slots in the above example cannot be used to transmit uplink signals in the second cell group, and the remaining slots may be.

For the second mode, if the first minimum guaranteed power and the second minimum guaranteed power are configured for the same time slot, the specific implementation manner of the first indication information may include N indication tuples, where the N indication tuples are in one-to-one correspondence with the N time slots (time slots); the nth indication tuple includes two indication fields, which are respectively denoted as indication field n1 and indication field n2. Specifically, the indication field N1 indicates that N minimum guaranteed powers in the first minimum guaranteed power group can be used to send uplink signals in the second cell group, and the indication field N2 indicates that the N minimum guaranteed powers in the second minimum guaranteed power group are only used to send uplink signals in the first cell group; i.e. the minimum guaranteed power in the second minimum guaranteed power group can only be used by the first cell group for transmitting uplink signals and cannot be shared to other cell groups.

For example, describing n=10 as an example, the first indication information indicates { (0.1,0.05), "(0.1,0.05)," (0.05, 0), "(0.1,0.05)," (0.1,0.05), "(0.2,0.1)," (0.2,0.1), "(0.2,0.1)," (0.2,0.1), ", etc. can be correspondingly used for the cell group with 15kHz subcarrier spacing; in the embodiment of the present application, in a specific application environment, n1 and n2 may implement the indication of the minimum guaranteed power in different manners, which may specifically be:

A1, taking the first indication tuple as an example of the first indication information, "'0.1,0.05', the minimum guaranteed power in the time slot 1, which can be used for sending uplink signals in the second cell group, is 0.1 xPmax; the minimum guaranteed power that can only be used for transmitting uplink signals at the first cell group is 0.05 x Pmax. That is, the minimum guaranteed power that can be used to transmit an uplink signal in the first cell group is (0.1+0.05) ×pmax; the first cell group is dedicated to 0.05×pmax, and the first cell group and the second cell group share 0.1×pmax.

A2, taking the first indication tuple 0.1,0.05 as an example in the first indication information, the minimum guaranteed power in the time slot 1, which can be used for sending uplink signals in the first cell group, is 0.1×Pmax, wherein the minimum guaranteed power that can be used only for sending uplink signals in the first cell group is 0.05×Pmax, and thus, the minimum guaranteed power that can be used for sending uplink signals in the second cell group is (0.1-0.05) ×Pmax.

The specific meaning of the other indication tuples is identical to the first time slot described above, so that it is not repeated here.

In addition, if both the first minimum guaranteed power and the second minimum guaranteed power are configured for the same time period, a specific implementation manner of the first indication information may include two sub-portions, where the first sub-portion includes N fields, an nth field is denoted as N1, the second sub-portion also includes N fields, and an nth field is denoted as N2. Specifically, the indication field N1 indicates that N minimum guaranteed powers in the first minimum guaranteed power group can be used to send uplink signals in the second cell group, and the indication field N2 indicates that the N minimum guaranteed powers in the second minimum guaranteed power group are only used to send uplink signals in the first cell group; i.e. the minimum guaranteed power in the second minimum guaranteed power group can only be used by the first cell group for transmitting uplink signals and cannot be shared to other cell groups.

For example, describing n=10 as an example, a cell group with 15kHz subcarrier spacing may be correspondingly used, where the first word portion in the first indication information includes {0.1,0.1,0.05,0.05,0.1,0.1,0.2,0.2,0.2,0.2}, and the second sub-portion includes {0.05,0.05,0,0 0.05,0.05,0.1,0.1,0.1,0.1}.

In this example, the network device configures two minimum guaranteed powers for the terminal device, so as to furthest improve the flexibility of the terminal device in uplink power control.

For the third mode, if the first minimum guaranteed power and the third minimum guaranteed power are configured for the same time slot, the specific implementation manner of the first indication information may include N indication tuples, where the N indication tuples are in one-to-one correspondence with the N time slots (time slots); the nth indication tuple includes two indication fields, which are respectively denoted as indication field n1 and indication field n2. Specifically, the indication field N1 indicates that N minimum guaranteed powers in a first minimum guaranteed power group are used to transmit a first type of uplink signal in a first cell group, and the indication field N2 indicates that the N minimum guaranteed powers in a third minimum guaranteed power group are used to transmit a second type of uplink signal in the first cell group.

For example: taking n=10 as an example, the first indication information indicates { (0.1,0.05), "(0.1,0.05)," (0.05, 0), "(0.1,0.05)," (0.1,0.05), "(0.2,0.1)," (0.2,0.1), "(0.2,0.1)," (0.2,0.1) }; taking the first indicator tuple as an example, "" 0.1,0.05 "", i.e., the minimum guaranteed power of 0.1×pmax in slot 1 is used to transmit the first type of uplink signal at the first cell group; a minimum guaranteed power of 0.05 x Pmax is used only for transmitting a second type of uplink signal at the first cell group; the specific meaning of the other indicating tuples is identical to that of the first indicating tuple, so that the description thereof will not be repeated here.

In addition, if both the first minimum guaranteed power and the second minimum guaranteed power are configured for the same time period, a specific implementation manner of the first indication information may include two sub-portions, where the first sub-portion includes N fields, an nth field is denoted as N1, the second sub-portion also includes N fields, and an nth field is denoted as N2. Specifically, the indication field N1 indicates that N minimum guaranteed powers in a first minimum guaranteed power group are used to transmit a first type of uplink signal in a first cell group, and the indication field N2 indicates that the N minimum guaranteed powers in a third minimum guaranteed power group are used to transmit a second type of uplink signal in the first cell group.

For example, describing n=10 as an example, a cell group with 15kHz subcarrier spacing may be correspondingly adopted, where the first word portion in the first indication information includes {0.1,0.1,0.05,0.05,0.1,0.1,0.2,0.2,0.2,0.2}, and the second sub-portion includes {0.05,0.05,0,0 0.05,0.05,0.1,0.1,0.1,0.1}.

When the first cell group is one of the cell groups, the terminal device needs to configure the power resources of each cell group in a feasible manner under the condition of limited power resources, and on the basis of the implementation steps shown in fig. 3, the method provided by the embodiment of the present application may further include the steps of:

step 305, the network device sends second indication information to the terminal device, where the second indication information indicates priorities of the plurality of cell groups for power allocation in the N time periods.

When the cell group comprises a plurality of cell groups, in the implementation manner, the network device can also send second indication information to the terminal device, and the second indication information can indicate the priorities among different cell groups in the same time period, so that the terminal device can perform power configuration of the cell group according to the priorities, and the power of the cell group with high priority can be preferentially ensured under the condition that the power limiting requirement is met by the method, so that the power of different cell groups can be reasonably configured, and meanwhile, the priority corresponding to the cell group can be flexibly adjusted according to the situation.

In combination with a specific usage scenario, the multiple cell groups may include the first cell group and the second cell group, where the priority is used for the terminal device to send uplink signals on the first cell group and the second cell group simultaneously, and if the total power of the uplink signals on the first cell group and the second cell group exceeds the maximum sending power, the sending power of the uplink signals on the cell group with low priority is reduced according to the priority.

Wherein the first cell group may be a primary cell group (e.g., MCG) and the second cell group may be a secondary cell group (e.g., SCG).

Of course, for the purpose of indicating different time periods, the second indication information includes N indication fields, where the N fields are in one-to-one correspondence with the N time periods; wherein each of the N fields is used to indicate a priority of the first cell group and the second cell group in a corresponding time period; n is a positive integer.

For example, in this embodiment, the period of time takes N slots included in one frame as an example, and the first indication information indicates the priority of the first cell group and the second cell group in at least one slot of the N slots. For example, the first indication information includes N indication fields, and the nth indication field indicates a priority of a cell group in the nth slot of the N slots, where 1< = N. Specifically, the n-th indication field includes 1 bit, where the priority of the first cell group is lower than that of the second cell group when the 1 bit is 0, and the priority of the first cell group is higher than that of the second cell group when the 1 bit is 1.

Taking n=10 as an example, the cell group may correspond to a 15kHz subcarrier spacing, where the first indication information includes 10 bits, which may have a value of 1100110011, and indicates that the first cell group in the 1 st, 2 nd, 5 th, 6 th, 9 th and 10 th slots in one frame has a higher priority than the second cell group, and the second cell group in the 3 rd, 4 th, 7 th and 8 th slots in one frame has a higher priority than the first cell group.

In this embodiment, at least one of the first indication information and the second indication information may be carried in downlink control information (Downlink Control Information, DCI), may be carried in radio access control (Radio Resource Control, RRC) signaling, may be carried in medium access control (Medium Access Control, MAC) signaling, or the like. Further, the signaling carrying at least one of the first indication information and the second indication information may be a signaling common to the cells, a signaling dedicated to the terminal, a signaling common to the terminal group, or the like.

In this embodiment, the first minimum guaranteed power/second minimum guaranteed power group only describes the N first minimum guaranteed powers/second minimum guaranteed powers uniformly, and it is not necessarily that a group entity is newly defined truly. In a specific implementation, a group entity may or may not be defined to include all N minimum guaranteed powers, which is not limited herein.

In the prior art, priorities of different signals and channels are predefined in a protocol, and a terminal device can determine the priority of a signal according to the type of uplink signals sent on carriers in an MCG and an SCG in the same time period, and reduce the power of a signal with low priority (the power of the signal can be reduced to 0), so that the power of a signal with high priority is preferentially ensured. The priority is determined in this prior art taking into account the type of signal and the type of CG, and if the types of signals transmitted simultaneously on both CGs are the same, the priority of the signal on the MCG is higher than the priority of the signal on the SCG. The priority among CGs is according to a default rule, e.g. MCG priority is higher than SCG, which allows all MCGs to have higher priority to use power over the time period, which has an impact on SCG performance. Therefore, in view of the prior art problem, an embodiment of the present application further provides an information transmission method in a dual connectivity scenario, where the method includes (as shown in fig. 4):

step 401, the network device determines N priorities for power allocation for a plurality of cell groups; the N priorities are in one-to-one correspondence with N time periods, wherein the N time periods are time periods included in one wireless frame, and N is a positive integer not less than 2;

In this embodiment, one priority is set for one period, and if the total transmission power of a plurality of cell groups exceeds the maximum transmission power in the same period, the transmission power of each cell group may be adjusted according to the priority corresponding to the period in the same period. The priority levels among the time periods are independently set, and the phenomenon that the total transmission power exceeds the maximum transmission power occurs in any time period can be carried out according to the priority level of the corresponding time period.

Step 402, the network device sends third indication information to the terminal device, where the third indication information indicates the N priorities.

Step 403, the terminal device receives the third indication information sent by the network device; wherein the third indication information indicates N priorities; the N priorities are used for distributing power among a plurality of cell groups in any time period;

and step 404, the terminal equipment allocates power to the cell group in any time period according to the third indication information.

The plurality of cell groups in this example may include the first cell group and the second cell group, and the priority is used for the terminal device to simultaneously transmit uplink signals on the first cell group and the second cell group, where the total power of uplink signals transmitted on the cell group with low priority is reduced according to the priority when the total power of uplink signals transmitted on the first cell group and the second cell group exceeds the maximum transmission power.

Optionally, the first cell group is a primary cell group (e.g., MCG) and the second cell group is a secondary cell group (e.g., SCG).

Optionally, in this embodiment, the third indication information may be carried in downlink control information (Downlink Control Information, DCI), may be carried in radio access control (Radio Resource Control, RRC) signaling, may also be carried in medium access control (Medium Access Control, MAC) signaling, and so on. Further, the signaling carrying at least one indication information of the third indication information may be a signaling common to the cells, a signaling dedicated to the terminal, a signaling common to the terminal group, or the like.

Optionally, the third indication information includes N indication fields, where the N fields are in one-to-one correspondence with N time periods; wherein each of the N fields is used to indicate a priority of the first cell group and the second cell group in a corresponding time period; n is a positive integer.

Optionally, the third indication information may be implicitly carried in other signaling sent by the network device to the terminal device. For example, the third indication information is implicit in uplink and downlink time domain resource allocation signaling, in the prior art, for a cell group operating in time division duplex (Time division duplex, TDD), the network device configures the uplink and downlink time domain resource allocation of the cell group to the terminal device, so that the terminal device determines which time periods are uplink and which time periods are downlink and which time periods are flexible time periods (flexible time periods are time periods that can be used for uplink communication and also can be used for downlink communication) in the cell group. In the case where the first cell group is a TDD cell group and the second cell group is a frequency division duplex (Frequency division duplex, FDD) cell group, one possible way is: for the uplink time period indicated by the uplink and downlink time domain resource allocation signaling corresponding to the first cell group, the priority of the first cell group is higher than that of the second cell group, and/or for the flexible time period indicated by the uplink and downlink time domain resource allocation signaling corresponding to the first cell group, the priority of the first cell group is lower than that of the second cell group. Another possible way is: and for the uplink time period and the flexible time period indicated by the uplink and downlink time domain resource allocation signaling corresponding to the first cell group, the priority of the first cell group is higher than that of the second cell group.

By the method provided by the embodiment, when the cell group comprises a plurality of cell groups, the network equipment can also send the second indication information to the terminal equipment, and the second indication information can indicate the priority among different cell groups, so that the terminal equipment can perform power configuration of the cell group according to the priority.

In this embodiment, after receiving the third indication information, the terminal device may send uplink signals on the first cell group and the second cell group simultaneously, where the total power of the uplink signals is greater than the maximum sending power, and then the terminal device may reduce, according to the priority in the third indication information, the sending power of the uplink signals sent on the cell group with low priority, so as to meet the power sending requirement of the uplink signals.
