In order to facilitate the understanding of the embodiments of the present application, which are exemplary, the following briefly introduces related terms involved in this document.

1. Time unit

The time unit in the embodiment of the present application is a collection of multiple consecutive symbols. For example, the time unit may be a minislot (minislot), a time slot (slot), a subframe (subframe), a transmission time interval (TTI), etc.

Among them, the symbols include uplink symbols (that is, symbols used for uplink transmission), downlink symbols (that is, symbols used for downlink transmission), and flexible symbols (which can be used for uplink transmission or downlink transmission or as a guard interval according to network configuration). The uplink symbol may be called, for example, a single carrier-frequency division multiple access (SC-FDMA) symbol or an orthogonal frequency division multiple access (OFDM) symbol. The downlink symbols may be called OFDM symbols, for example.

2. Time slot

One slot includes at least one symbol. A time slot containing all uplink symbols may be referred to as an uplink time slot, which is represented by U in the embodiment of the present application. A time slot containing all downlink symbols may be referred to as a downlink time slot, which is represented by D in the embodiment of the present application. A time slot containing multiple symbols among uplink symbols, downlink symbols, and flexible symbols may be referred to as flexible time slots, which is represented by S in the embodiment of the present application.

In NR, according to different sub-carrier intervals, 1 millisecond (ms) can include different numbers of time slots. For example, when the sub-carrier interval is 15 kilohertz (kHz), 1 ms includes 1 time slot, which occupies 1ms. When the subcarrier spacing is 30kHz, 1ms includes 2 time slots, and each time slot occupies 0.5ms.

3. Time division duplex (time division deplux, TDD)

TDD is a duplex communication technology for communication systems, which is used to separate channels for receiving and sending, that is, uplink and downlink. In the communication system adopting the TDD mode, the same frequency domain resources are used for the uplink and downlink, and the uplink and the downlink are distinguished by different time domain resources.

In this case, a carrier (component carrier, CC) whose duplex mode is TDD may be referred to as a TDD carrier.

4. Frequency division duplex (time division depluxing, FDD)

FDD is a duplex communication technology for communication systems, which is used to separate channels for receiving and sending, that is, uplink and downlink. In a communication system using the FDD mode, the uplink and downlink use the same time domain resources, and different frequency domain resources are used to distinguish the uplink from the downlink. For example, the uplink frequency range is different from the downlink frequency range.

In this case, the carrier whose duplex mode is FDD may be referred to as an FDD carrier.

5. Multi-carrier uplink transmission

Multi-carrier uplink transmission refers to the presence of multiple carriers between the terminal and network equipment in the uplink direction. A terminal can access one network device, and multiple carriers can include the carrier between the terminal and one network device, or the terminal can access two network devices at the same time, and multiple carriers can include the communication between the terminal and the two network devices. Carrier.

Exemplarily, scenarios of multi-carrier uplink transmission may include scenarios such as carrier aggregation (CA), dual connectivity (DC), and supplementary uplink (SUL).

Exemplarily, during multi-carrier uplink transmission, the uplink transmission may be performed in a time division multiplexing (TDM) manner, or the uplink transmission may be performed in a concurrent (ie, simultaneous uplink transmission) manner.

6. CA

Limited by factors such as the shortage of wireless spectrum resources, the spectrum resources owned by operators are non-continuous, and each single frequency band cannot meet the bandwidth requirements of 5G networks. Based on the above reasons, CA has also been introduced into 5G networks. CA refers to a technology that aggregates multiple continuous or non-contiguous carriers to form a larger bandwidth. CA can achieve the purpose of increasing the communication rate.

CA can be divided into uplink CA and downlink CA. For uplink CA, the terminal can simultaneously receive or transmit on multiple carriers according to its capabilities. Exemplarily, referring to Fig. 2, a carrier 1 with a bandwidth of 60 megabytes (M) (for example, a 3.5 GHz carrier) and a carrier 2 with a bandwidth of 20 M (for example, a 1.8 GHz carrier) can be aggregated into a bandwidth of 80 M through uplink CA, thereby Improve uplink transmission performance.

7. DC

In the current communication system, the terminal supports simultaneous access to two different nodes. This access method is called DC. In this case, the terminal may use the radio resources of one or more of the two nodes for transmission, and the two nodes may be of the same standard or of different standards.

One of the two different nodes is the primary node, and the other node is the secondary node. The link between two nodes can be a non-ideal backhaul link or an ideal backhaul link. The two different nodes can be different network devices, or different modules in the same network device, and one module can correspond to one cell.

Exemplarily, the two different nodes may be two base stations in a non-standalone (NSA) networking scenario based on evolved packet core (EPC). In this case, the two The base station may be an LTE base station and an NR base station. The two different nodes may also be two base stations in a standalone (SA) scenario. In this case, the two base stations may be both LTE base stations or NR base stations.

Among them, the terminal can communicate with one of the two different nodes through multiple carriers. For example, referring to Figure 3, if the two different nodes are an LTE base station and an NR base station, the terminal can communicate with LTE through multiple carriers. For base station communication, uplink CA and/or downlink CA can be performed between these multiple carriers. Multiple carriers can also be used to communicate with the NR base station, and uplink CA and/or downlink CA can be performed between these multiple carriers.

8. SUL

The coverage of different frequency bands is different. Generally, the lower the frequency, the greater the coverage. For example, the coverage of the 1.8GHz frequency band is greater than that of the 3.5GHz frequency band, and the coverage of the 0.9GHz frequency band is greater than that of the 1.8GHz frequency band. In order to improve the uplink coverage performance, the 5G network introduces uplink and downlink decoupling technology to decouple the frequency bands of uplink transmission and downlink transmission, that is, the frequency band used for uplink transmission can be different from the frequency band used for downlink transmission. For example, a terminal uses the 3.5 GHz frequency band for downlink transmission and the 1.8 GHz frequency band for uplink transmission to improve uplink coverage and effectively use resources.

SUL is the supplementary uplink configured by the terminal. The purpose is to improve the uplink coverage of the terminal. Exemplarily, referring to FIG. 4, the terminal may send uplink information through a normal uplink (NUL), and may also send uplink information through SUL. The coverage of NUL may be smaller than that of SUL. The multiple carriers in the SUL scenario refer to SUL and NUL.

9. TDM

TDM is a way of data transmission. When the terminal uses TDM to transmit on multiple carriers, the time domain resource used for uplink transmission of each of the multiple carriers is not the same as the time domain resource used for uplink transmission of any other carrier in the multiple carriers overlapping. Exemplarily, the multiple carriers may be part or all of all carriers supported by the terminal. It can be understood that multiple carriers will not perform uplink transmission on the same time domain resource.

Exemplarily, for the 2.6GHz carrier and the 3.5GHz carrier, if the time slot configuration of the two carriers is as shown in Figure 5, the terminal can transmit uplink through the 2.6GHz carrier in the time slot 3 corresponding to the 2.6GHz carrier, and the terminal can use The 3.5GHz carrier performs uplink transmission in the time slot 9 corresponding to the 3.5GHz carrier and the time slot 4 corresponding to the 3.5GHz carrier (that is, the first half of the time slot 2 of the 2.6GHz carrier), then the 2.6GHz carrier or the 3.5GHz carrier is TDM of.

The TDM transmission method may also be referred to as a time-sharing transmission method.

10. Concurrency

Concurrency is a way of data transmission, which means simultaneous uplink transmission. When the terminal is concurrent on multiple carriers, the time domain resources used for uplink transmission of each of the multiple carriers overlap with the time domain resources used for uplink transmission of each of the other carriers. Exemplarily, the multiple carriers may be part or all of all carriers supported by the terminal.

Exemplarily, referring to FIG. 5, in the first half of the time slot of time slot 2 corresponding to the 2.6 GHz carrier (that is, time slot 4 corresponding to the 3.5 GHz carrier), the terminal performs uplink transmission on the 2.6 GHz carrier and the 3.5 GHz carrier at the same time, then In the first half of time slot 2 corresponding to the 2.6 GHz carrier, the 2.6 GHz carrier and the 3.5 GHz carrier are concurrent.

11. Specific absorption rate (SAR) indicator requirements

In order to control the electromagnetic power absorbed or consumed by human tissues within a certain standard, the SAR indicator requirements stipulate that the average uplink transmit power of the terminal within a period of time (for example, a radio frame or subframe) shall not exceed (ie, less than or equal to) 23 millimetres. Milliwatt decibel (dBm).

12. Capability information of the terminal

In 5G networks, frequency bands are divided, and different frequency bands correspond to different duplex modes. The SUL frequency band is also defined in the 5G network, which is used for uplink transmission. See Table 1. Table 1 shows an example of the division of different frequency bands. For FDD duplex mode, the uplink and downlink are transmitted on different frequency bands. For the TDD duplex mode, the uplink and the downlink share the same spectrum resources, and transmit through different time domain resources.

A combination of frequency bands supporting CA is also defined in the 5G network. Exemplarily, Table 2 shows an example of CA frequency band combination.

In a 5G network, after a terminal accesses the network, it will report to the network equipment the frequency bands supported by the terminal and the combination of CA frequency bands supported by the terminal through the capability information of the terminal, as well as the radio frequency capabilities of each frequency band (for example, maximum transmission power, multiple input and multiple output (multi-input multi-output, MIMO) capability, etc.) and the radio frequency capability of each frequency band in the CA frequency band combination (for example, maximum transmit power, MIMO capability).

Exemplarily, the 3.5 GHz carrier is a TDD carrier, and the maximum transmission power is 26 dBm, and the 2.1 GHz carrier is an FDD carrier, and the maximum transmission power is 23 dBm. The capability information of the terminal may include that the 3.5GHz carrier supports 2T transmission (T in the embodiment of this application refers to the radio frequency channel) transmission, the maximum number of MIMO streams is 2 streams, the maximum transmission power is 26dBm, the 2.1GHz carrier supports 1T transmission, and the maximum number of MIMO streams 1 stream, the maximum transmit power is 23dBm, when the 3.5GHz carrier and 2.1GHz carrier are combined, the number of MIMO streams per carrier is 1 stream, and the transmit power is 20dBm.

It should be noted that the uplink transmit power of the terminal on a carrier is limited by the number of radio frequency channels supported by the carrier. For example, in general, when the terminal supports 1T transmission on this carrier, the uplink transmission power of the terminal on this carrier can only reach 23dBm. When the terminal supports 2T transmission on this carrier, the terminal’s uplink transmission on this carrier The power can reach 26dBm.

At present, the maximum transmission power supported by some TDD carriers (such as 2.6GHz carrier and 3.5GHz carrier) defined in the 5G standard is 26dBm, and the default maximum transmission power supported by FDD carriers or other TDD carriers is 23dBm. In addition, in the SUL scenario, in order to meet the SAR indicator requirements, regardless of whether the SUL carrier or the NUL carrier is a TDD carrier or an FDD carrier, the maximum transmit power on the SUL carrier and the NUL carrier is 23dBm.

In the DC scenario or the uplink CA scenario, the network device can configure the maximum transmit power allowed on each carrier through radio resource control (radio resource control, RRC) signaling to ensure that the average transmit power on all time slots does not exceed For the maximum transmit power supported by each carrier, the network equipment will configure the terminal with the maximum transmit power allowed by each carrier according to the scenario of multi-carrier concurrency. At this time, the maximum transmission power allowed for at least one of the multiple carriers configured by RRC signaling should be reduced to half of the maximum transmission power supported by the corresponding carrier, or in other words, at least one of the multiple carriers configured by RRC signaling is allowed The maximum transmission power used is 3dB lower than the maximum transmission power supported by the corresponding carrier. In this case, in timeslots other than timeslots where multiple carriers are concurrent, the transmit power of the terminal on at least one of the multiple carriers cannot exceed half of the maximum transmit power supported by the corresponding carrier, resulting in these carriers The actual transmission power of the carrier cannot reach the maximum transmission power supported by the carrier, so that spectrum resources cannot be effectively used.

For example, if the maximum transmission power supported by carrier 1 is 26 dBm and the maximum transmission power supported by carrier 2 is 23 dBm, the maximum transmission power of the terminal is 26 dBm. At this time, the maximum transmit power allowed for carrier 1 configured by RRC signaling is 23 dBm, and the maximum transmit power allowed for carrier 2 is 23 dBm. That is, the actual transmit power on carrier 1 cannot reach the maximum transmit power supported by the carrier, so it cannot Effective use of spectrum resources. For another example, if the maximum transmission power supported by carrier 1 is 23 dBm and the maximum transmission power supported by carrier 2 is 23 dBm, the maximum transmission power of the terminal is 23 dBm. At this time, the maximum transmission power allowed for carrier 1 and carrier 2 configured by RRC signaling are both 20 dBm, that is, the actual transmission power on the two carriers cannot reach the maximum transmission power supported by the corresponding carrier, so that spectrum resources cannot be effectively used.

In order to improve the utilization of spectrum resources, an embodiment of the present application provides a power configuration method. In this method, the network device can configure the maximum transmission power allowed by the terminal carrier as the maximum transmission power supported by the carrier, thereby increasing the frequency. Resource utilization and user rate and network throughput.

The method provided in the embodiments of the present application can be applied to any multi-carrier scenario. Optionally, the terminal may be located in the overlapping coverage area of multiple carriers, and the terminal may select different carriers for uplink transmission. Multi-carrier scenarios include, but are not limited to, any of the aforementioned DC scenarios, CA scenarios, or SUL scenarios.

The carrier in the embodiment of the present application may be an FDD carrier or a TDD carrier.

The carrier in the embodiment of the present application may be, for example, a 3.5 GHz carrier, a 2.6 GHz carrier, a 1.8 GHz carrier, a 900 megahertz (M) Hz carrier, and the like.

In the embodiments of the present application, carrier and frequency band have the same meaning, and different places in this document may have different descriptions, but the essence of the two descriptions is the same.

As shown in FIG. 6 or FIG. 7, the power configuration method provided by the embodiment of the present application includes:

601. The network device obtains first configuration information.

Exemplarily, the first configuration information includes information about the maximum transmit power allowed on each of the multiple carriers of the terminal, and the maximum transmit power allowed by the terminal on one of the multiple carriers (denoted as the first carrier) The transmit power is the maximum transmit power supported by the first carrier. The multiple carriers may be some or all of the carriers configured by the network device for the terminal. The first carrier may be any one of the multiple carriers.

The information about the maximum transmit power supported by each of the multiple carriers in the network equipment can be pre-configured or obtained from the terminal. If it is the latter, optionally, refer to FIG. 7. Before step 601, the method further includes: 600. The terminal sends the capability information of the terminal to the network device. Correspondingly, the network device receives the capability information of the terminal from the terminal.

Exemplarily, the capability information of the terminal includes information about the maximum transmit power supported by each carrier in the multiple carriers. Exemplarily, if the multiple carriers are 3.5GHz carrier and 2.1GHz carrier, the capability information of the terminal may include information that the maximum transmit power supported by the 3.5GHz carrier is 26dBm and the information that the maximum transmit power supported by the 2.1GHz carrier is 23dBm .

In this case, when step 601 is specifically implemented, it may include: the network device obtains the first configuration information according to the capability information of the terminal. Exemplarily, the network device may determine the maximum transmission power supported by each of the multiple carriers according to the capability information of the terminal, and determine the maximum transmission power supported by each carrier as the maximum transmission power allowed by the carrier.

Optionally, the capability information of the terminal may be carried in RRC signaling or message 3 (Message 3, which may be referred to as Msg3 for short) in the RRC signaling or random access process.

602. The network device sends first configuration information to the terminal. Correspondingly, the terminal receives the first configuration information from the network device.

Exemplarily, if the capability information of the terminal includes the information that the maximum transmit power supported by the 3.5GHz carrier is 26dBm and the information that the maximum transmit power supported by the 2.1GHz carrier is 23dBm, the first configuration information sent by the network device to the terminal includes the information The information may be: the maximum transmit power allowed for the 3.5GHz carrier is 26dBm and the maximum transmit power allowed for the 2.1GHz carrier is 23dBm.

Optionally, the first configuration information may be carried in RRC signaling or Msg3.

603. The terminal performs uplink transmission on multiple carriers according to the first configuration information.

When step 603 is specifically implemented, the uplink transmission power used by the terminal when performing uplink transmission on one of the multiple carriers cannot exceed (that is, less than or equal to) the maximum transmission power allowed by the carrier.

Optionally, referring to FIG. 7, the method further includes step 604, or, step 604 and step 605.

604. The network device sends second configuration information to the terminal. Correspondingly, the terminal receives the second configuration information from the network device.

Exemplarily, the second configuration information includes the uplink transmission power used by the terminal on at least one of the multiple carriers in the first time unit used for uplink transmission, and the at least one carrier is used by the terminal for uplink transmission in the first time unit. Carrier, the sum of the uplink transmit power used by the terminal on at least one carrier is less than or equal to the maximum transmit power of the terminal.

Optionally, in the first time unit, at least two of the multiple carriers are concurrent, and the sum of the uplink transmit power used by the terminal on the at least two carriers is less than or equal to the maximum transmit power of the terminal; or, at the first time On the unit, one of the multiple carriers performs uplink transmission, and the uplink transmission power used by the terminal on this carrier is less than or equal to the maximum transmission power of the terminal.

Exemplarily, the first time unit may be any time unit. A time unit can be a time slot of a certain carrier among multiple carriers, or a fixed-length time domain resource, for example, 7 symbols, or other values. For details, please refer to the relevant description above. I will not repeat them here.

The network device may transmit the uplink transmit power of one or more carriers for uplink transmission on each time unit of the schedule. Here, the first time unit is taken as an example for description.

Exemplarily, referring to FIG. 8, the 3.5 GHz carrier is a TDD carrier, and the maximum supported transmission power is 26 dBm, and the 2.1 GHz carrier is an FDD carrier, and the maximum supported transmission power is 23 dBm. Taking into account the requirements of SAR indicators, for the concurrent time unit of the 3.5GHz carrier and the 2.1GHz carrier, that is, time slot 4 of the 3.5GHz carrier (that is, the first half time slot of the time slot 2 of the 2.1GHz carrier), the second configuration information may include The uplink transmission power used by the 3.5GHz carrier is 20dBm, and the uplink transmission power used by the 2.1GHz carrier is 20dBm. In time slot 8 and time slot 9 of the 3.5 GHz carrier, the terminal only performs uplink transmission on the 3.5 GHz carrier, and the second configuration information may include information that the uplink transmission power used by the 3.5 GHz carrier is 23 dBm. In timeslot 0, timeslot 1, the second half of timeslot 2 and timeslot 3 of the 2.1GHz carrier, the terminal only performs uplink transmission on the 2.1GHz carrier, and the second configuration information may include the uplink used by the 2.1GHz carrier The transmit power is 23dBm information.

Exemplarily, the maximum transmission power of the terminal is the maximum transmission power with the largest value among the maximum transmission powers allowed to be adopted by the multiple carriers configured by the first configuration information. For example, if the information contained in the first configuration information sent by the network device to the terminal may be: the maximum transmission power allowed for the 3.5GHz carrier is 26dBm and the maximum transmission power allowed for the 2.1GHz carrier is 23dBm, the terminal The maximum transmit power is 26dBm. If the information contained in the first configuration information sent by the network device to the terminal can be: the maximum transmission power allowed for the 1.8GHz carrier is 23dBm and the maximum transmission power allowed for the 2.1GHz carrier is 23dBm, the terminal’s maximum The transmit power is 23dBm.

Optionally, the second configuration information may be carried in MAC CE signaling or downlink control information (downlink control information, DCI).

605. In the first time unit, the terminal performs uplink transmission on at least one carrier according to the second configuration information.

When step 605 is specifically implemented, the terminal uses the uplink transmission power of at least one carrier configured by the second configuration information to perform uplink transmission on the at least one carrier. If the at least one carrier is multiple carriers, the terminal concurrently transmits on the at least one carrier, and if the at least one carrier is a single carrier, the terminal performs uplink transmission on the single carrier.

In the method provided by the embodiment of the present application, the network device can configure the terminal with the maximum transmission power supported by each of the multiple carriers of the terminal as the maximum transmission power allowed by the carrier, so that the terminal can transmit uplink on one carrier. The power can reach the maximum supported transmission power. Because the higher the uplink transmission power, the same spectrum resource can carry more information, so as to maximize the use of spectrum resources and improve user rate and network throughput.

In addition, the network equipment can also configure the uplink transmission power of each of the one or more carriers for uplink transmission on each time unit scheduled for the terminal, and ensure one or more uplink transmission power for each time unit. The sum of the uplink transmit power of the carrier is less than or equal to the maximum transmit power of the terminal, so as to ensure that the average transmit power of each carrier on all time units does not exceed the maximum supported transmit power and meet the SAR indicator requirements. In addition, the uplink transmission power used by each carrier can be equal to the maximum transmission power supported by the carrier, so as to maximize the use of spectrum resources and improve user rate and network throughput.

When the foregoing step 604 is specifically implemented, it may include the following steps 1 to 3:

Step 1. The network device determines whether a single carrier is used for transmission or multiple carriers are used concurrently for each of the N time units.

Exemplarily, the N time units are all uplink time domain resources. Exemplarily, when the time unit is a time slot, the N time units may be N uplink time slots.

It should be noted that although the network device configures uplink time domain resources for a carrier, whether the terminal can perform uplink transmission in the uplink time domain resources of the carrier depends on the configuration of the network device. For example, the network device configures 10 uplink time slots for the terminal. Illustratively, 6 uplink time slots can be used for uplink transmission, and the remaining 4 uplink time slots cannot be used for uplink transmission. In the embodiment of the present application, the time domain resources that can be used for uplink transmission among the uplink time domain resources are referred to as uplink transmission resources.

Step 1 can be implemented in the following way 1 or way 2 in specific implementation.

method one

For a time unit, if the time domain resources of multiple carriers all include the time unit, the network device determines that the terminal concurrently uses the multiple carriers on the time unit. If the time domain resource of only one carrier includes the time unit, the network device determines that the terminal on the time unit only performs uplink transmission on this carrier.

Exemplarily, if the positions of the uplink transmission resources of the 3.5GHz carrier and the 2.1GHz carrier are shown in Figure 8, assuming that the time unit is a time slot of the 3.5GHz carrier, the network device can determine the time slot 0 and time slot of the 3.5GHz carrier 1. Only 2.1GHz carrier is used for uplink transmission on time slot 2, time slot 3, time slot 5, time slot 6, and time slot 7, and only 3.5GHz carrier is used on time slot 8 and time slot 9 of 3.5GHz carrier For uplink transmission, the terminal concurrently transmits on the 3.5 GHz carrier and the 2.1 GHz carrier in the time slot 4 of the 3.5 GHz carrier.

Way two

The network device determines that uplink transmission is performed on only one carrier in each time unit, that is, multiple carriers are used for uplink transmission in the TDM manner.

In the second mode, the network equipment can ensure that the terminal performs uplink transmission in the TDM mode on multiple carriers through the following methods (1), (2) or (3).

Method (1): The network equipment ensures that the uplink time domain resources configured for multiple carriers do not overlap. In this case, multiple carriers may all be TDD carriers.

In the DC scenario, when method (1) is specifically implemented, the primary network device and the secondary network device can determine the time domain resource configuration of each carrier of the terminal through negotiation to ensure that the uplink time domain resources of different carriers do not overlap. Exemplarily, if the main network device and the auxiliary network device are both NR base stations, the main network device and the auxiliary network device may negotiate through the Xn interface. If one of the main network device and the auxiliary network device is an LTE base station and the other is an NR base station, the main network device and the auxiliary network device can negotiate through the X2 interface.

In the CA scenario, the network equipment can determine the time domain resource configuration of each carrier of the terminal by itself to ensure that the uplink time domain resources of different carriers do not overlap.

Exemplarily, the time domain resources configured by the network equipment for carrier 1 and carrier 2 of the terminal can be seen in FIG. 9. Exemplarily, both carrier 1 and carrier 2 are TDD carriers, the subcarrier interval of carrier 1 is 30 kHz, the subcarrier interval of carrier 2 is 15 kHz, and the uplink time domain resources of carrier 1 and carrier 2 do not overlap.

Manner (2): The network equipment ensures that the uplink transmission resources in the uplink time domain resources configured for multiple carriers do not overlap.

In this case, any one of the multiple carriers may be a TDD carrier or an FDD carrier.

Method (2) can be implemented by configuring TDM patterns in specific implementation. In this case, the network device can configure the uplink transmission resources in the uplink time domain resources on one or more of the multiple carriers through the cell TDM pattern configuration ("tdm-PatternConfig") in the RRC signaling.

The mode (2) can be specifically realized by the following mode (2-1) or mode (2-2).

Manner (2-1): The network device indicates the uplink transmission resources of the uplink time domain resources of multiple carriers of the terminal based on a fixed map that has been negotiated with the terminal.

Exemplarily, the fixed pattern can be seen in Table 3. In Table 3, U indicates that uplink transmission can be performed, and the rest indicate that uplink transmission cannot be performed.

table 3

Based on the fixed map shown in Table 3, the network device can configure an entry in the map for carrier 1 of the terminal. When the time slot of carrier 1 and the time slot with the same number in the table entry are all uplinks In a time slot, it means that the terminal on this time slot of carrier 1 can perform uplink transmission, otherwise it means that the terminal on this time slot cannot perform uplink transmission. Exemplarily, referring to FIG. 10, if the network device configures the table entry 0 in the carrier 1 map, it means time slot 2, time slot 3, time slot 4, time slot 7, time slot 8 and Time slot 9 can perform uplink transmission. Since only time slot 4 and time slot 9 in carrier 1 are uplink time slots, the terminal can only perform uplink transmission on time slot 4 and time slot 9. For carrier 2, the terminal can perform uplink transmission on uplink time domain resources that do not overlap with the uplink transmission resources in the uplink time domain resources of carrier 1 by default. Exemplarily, referring to FIG. 10, if it is on carrier 1, the terminal can only perform uplink transmission in time slot 4 and time slot 9. Then, on carrier 2, the terminal can perform uplink transmission in time slot 0, time slot 1, and time slot 3.

Method (2-2): The network equipment directly uses RRC signaling to flexibly configure whether uplink transmission is allowed on each time slot of each carrier.

Exemplarily, referring to Figure 10, the information configured by the network equipment for carrier 1 can be found in Table 4, and the information configured by the network equipment for carrier 2 can be found in Table 5. 1 means that the uplink time slot can perform uplink transmission, and 0 means that the uplink time slot cannot Perform upstream transmission. In this case, on carrier 1, the terminal can only perform uplink transmission on time slot 4 and time slot 9, and on carrier 2, the terminal can perform uplink transmission on time slot 0, time slot 1 and time slot 3.

Table 4

Slot number 0 1 2 3 4 5 6 7 8 9 Uplink sending instructions 0 0 0 0 1 0 0 0 0 1

table 5

Slot number 0 1 2 3 4 Uplink sending instructions 1 1 0 1 0

In the DC scenario, when the method (2) is specifically implemented, the primary network device and the secondary network device can negotiate to determine which uplink time domain resources of the uplink time domain resources of each carrier of the terminal can be sent upstream, so as to ensure different In the uplink time domain resources of the carrier, the uplink time domain resources capable of uplink transmission do not overlap. Exemplarily, if the main network device and the auxiliary network device are both NR base stations, the main network device and the auxiliary network device may negotiate through the Xn interface. If one of the main network device and the auxiliary network device is an LTE base station and the other is an NR base station, the main network device and the auxiliary network device can negotiate through the X2 interface.

In the CA scenario, the network equipment can determine by itself which uplink time domain resources of the uplink time domain resources of each carrier of the terminal can be sent uplink, so as to ensure the uplink time domain resources that can be sent in the uplink time domain resources of different carriers Does not overlap.

Regarding the overlapping uplink time domain resources of different carriers, the network equipment can determine the uplink throughput rate and/or blocking rate of different carriers. The partially overlapping uplink time domain resources are used on the carrier with higher uplink throughput rate and/or lower blocking rate. Uplink can be sent on.

Method (3): Through network equipment scheduling, the terminal implements uplink transmission in TDM mode on N carriers.

In this case, any one of the multiple carriers may be a TDD carrier or an FDD carrier.

The network equipment can ensure that the time domain resources used by the terminal for uplink transmission on different carriers do not overlap through scheduling, that is, it can ensure that there will be no concurrency between different carriers. Exemplarily, referring to Figure 5, the terminal can schedule the terminal's uplink data in time slot 3 of the 2.6GHz carrier, and schedule the terminal's uplink data in time slot 9 of the 3.5GHz carrier, and in the first half of time slot 2 of the 2.6GHz carrier Slot (that is, time slot 4 of the 3.5GHz carrier), the terminal schedules the terminal's uplink data on the 2.6GHz carrier or the 3.5GHz carrier.

The second method can avoid the problem of the decrease of the uplink transmission power of the carrier caused by the concurrency of multiple carriers.

Step 2. The network equipment determines the actual transmission rate of each carrier on each time unit according to the proportion of uplink transmission resources in the N time units and the transmission mode (single shot or concurrent) on each time unit in the N time units. Maximum transmit power.

Taking into account the requirements of SAR indicators, the average uplink transmit power of the terminal in N time units does not exceed 23 dBm. Considering the maximum transmission power of the terminal, in a time unit, the uplink transmission power of the terminal (that is, the sum of the uplink transmission power on multiple carriers) does not exceed the maximum transmission power of the terminal. When these two conditions are met, the uplink transmit power of the terminal can be increased as much as possible. In each time unit, the network device can control the terminal's uplink transmit power not to exceed the actual maximum transmit power through closed-loop power control.

For example, when the proportion of uplink transmission resources in N time units is less than 1, the uplink transmission power on part of the time units can be increased. For example, for a carrier with a maximum supported transmission power of 26 dBm, part of the time unit can be increased. The uplink transmit power on the unit has been increased from 23dBm to 26dBm.

Exemplarily, referring to FIG. 11, the 3.5 GHz carrier is a TDD carrier, and the maximum supported transmission power is 26 dBm, and the 2.1 GHz carrier is an FDD carrier, and the maximum supported transmission power is 23 dBm, and the maximum transmission power of the terminal is 26 dBm. Since the terminal does not perform uplink transmission in time slot 5 of the 3.5 GHz carrier, the uplink transmission power of time slot 5 can be used to enhance the uplink transmission power of time slot 4. At this time, the network equipment can determine that the actual maximum transmit power of the 2.1GHz carrier on the 3.5GHz carrier in time slot 0, time slot 1, time slot 2, time slot 3, time slot 6, and time slot 7 is 23 dBm. The actual maximum transmit power of the 3.5GHz carrier on time slot 8 and time slot 9 of the carrier is 23dBm, and the actual maximum transmit power of the 3.5GHz carrier on time slot 4 of the 3.5GHz carrier is 26dBm.

Step 3. The network device sends second configuration information to the terminal.

Before step 3, the network device can determine the uplink transmission power used by each carrier for uplink transmission on the first time unit, which can be specifically implemented in the following implementation manner 1 and implementation manner 2.

Implementation method 1

In the case where the actual required uplink transmit power of a carrier for uplink transmission on the first time unit is less than or equal to the actual maximum transmit power of the carrier, the network device can determine that the uplink transmit power used by the carrier is the actual uplink transmit power of the carrier Power, the uplink transmit power actually required by a carrier can be determined according to the hybrid automatic repeat request (HARQ) feedback sent by the terminal, channel state information (CSI) and other information. For details, please refer to the prior art , I won’t repeat it here.

Realization 2

In order to improve the uplink transmission efficiency of the terminal, the network device may always determine that the actual maximum transmission power of a carrier for uplink transmission in the first time unit is the uplink transmission power used by the carrier.

In this case, optionally, among the N time units including the first time unit, if the proportion of time units used for uplink transmission is less than 1, at least two of the multiple carriers on the first time unit In the case of concurrent, the sum of the uplink transmit power used by the terminal on at least two carriers is equal to the maximum transmit power of the terminal; or, when one of the multiple carriers on the first time unit performs uplink transmission, the terminal is The uplink transmit power used on the carrier is equal to the maximum transmit power of the terminal.

This optional method ensures that the average transmit power of each carrier on all time units does not exceed the maximum supported transmit power, so that the uplink transmit power used by each carrier for uplink transmission on the first time unit can be maximized , Thereby improving the data transmission efficiency on the first time unit.

In order to make the embodiments of the present application clearer, the method provided in the foregoing embodiment is exemplified below by taking the method provided in the foregoing embodiment applied to the SUL scenario as an example. In the SUL scenario, multiple carriers are SUL carriers and NUL carriers. In this example, the NUL carrier is a TDD carrier, and the network equipment schedules the terminal to use TDM for uplink transmission between these two carriers. See Figure 12, The method includes:

1201. A terminal sends an RRC message to a network device. The RRC message includes capability information of the terminal. The capability information of the terminal includes information about the maximum transmit power supported by the SUL carrier and the maximum transmit power supported by the NUL carrier.

Exemplarily, the SUL carrier may be n3, the maximum supported transmission power may be 23 dBm, the NUL carrier may be n78, and the maximum supported transmission power may be 26 dBm.

1202. The network device may configure two carriers for the terminal according to the capability information of the terminal, that is, the SUL carrier and the NUL carrier.

After step 1202, the terminal may send a response indicating that the carrier configuration is successful to the network device.

1203. The network device sends first configuration information to the terminal, where the first configuration information includes information that the maximum transmission power allowed for the SUL carrier is 23 dBM and information that the maximum transmission power allowed for the NUL carrier is 26 dBM.

1204. The network device sends second configuration information to the terminal, where the second configuration information includes information about the uplink transmission power used by the carrier (SUL carrier or NUL carrier) for uplink transmission in the first time slot.

In each time slot, the network device can indicate whether the terminal performs uplink transmission on the NUL carrier or the SUL carrier through the uplink/uplink supplemental link indication (UL/SUL indication) field in the DCI. The second configuration information may be carried in the DCI or other messages, which is not specifically limited in the embodiment of the present application.

1205. The terminal uses the uplink transmission power of the carrier configured by the second configuration information to perform uplink transmission in the first time slot.

After step 1204, the network device can continue to send second configuration information to the terminal to configure the uplink transmission power used by the carrier (SUL carrier or NUL carrier) for uplink transmission in other time slots, and the terminal can use the corresponding carrier for uplink transmission Power for uplink transmission.
