Description

Power control method and terminal device

The present application claims priority to Chinese Patent Application No. 200910314125.5, entitled "A Power Control Method and Terminal Equipment", filed on May 5, 2017, the entire contents of which is incorporated herein by reference. in.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a power control method and a terminal device.

Background technique

The power control is to change the transmission power of the User Equipment (UE) or the eNodeB in a wireless manner to compensate the path loss and shadow fading of the channel and suppress inter-cell interference.

The specific implementation of the power allocation of the Long Term Evolution (LTE) system may be:

After receiving the uplink resource allocated by the base station, the terminal device calculates the power of transmitting data by using the uplink resource.

If the sum of the powers on the resources of the activated serving cell on a certain time zone is greater than the maximum output power of the UE, then power adjustment is needed at this time. That is, the power corresponding to the resources of some channels is adjusted by the power factor of the channel to ensure that the power in a certain time zone is not greater than the maximum output power of the UE. The specific power adjustment rule is: different power factors are set for different channels to adjust the power of the resource, but for the intra-channel resources, there is no specific power adjustment mechanism, so that the service power allocation of different requirements of the same channel is unreasonable. As a result, some business requirements cannot be met, and the delay in data transmission using these resources increases the reliability.

In addition, with the continuous development of the long-term evolution system and the continuous research of the fifth-generation mobile communication, the resources for data transmission of the terminal device may overlap at least two in time, and the terminal device calculates each resource separately at the overlapping time. The corresponding power is used as the transmission power. In this case, the sum of the transmission power of each resource may exceed the maximum power that the terminal can transmit, which may result in the data transmitted on each resource not being correctly transmitted.

detailed description

For a more detailed description of the specific implementation process of the solution provided by the present invention, the method provided by the embodiment of the present application is further described in detail below with reference to specific examples:

The method provided by the present application implements resource-based power adjustment, and can implement power adjustment of a single physical channel (or signal) and multiple physical channels (or signals). The physical channel may include: a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), and a physical random access channel (PRACH); The physical channel that can be referred to in the embodiment of the present application can also be interpreted as a physical signal, where the physical signal can be: a sounding reference (sounding reference) Signal, SRS).

In order to explain the method provided by the present application in more detail, the scheme of the present application is further described by taking a single physical channel or multiple physical channels as an example.

Embodiment 1

For a single physical channel or signal, as shown in FIG. 1 , the embodiment of the present application provides a power control method, where the method may specifically include the following implementation steps:

Step 101: The terminal device determines at least two resources, where the at least two resources have a first overlapping area in the time domain, and each of the at least two resources corresponds to a first power in the first overlapping area;

In the embodiment of the present application, the manner of determining at least two resources may be:

A1. The terminal device receives at least one indication of the network device.

The manner in which the terminal device receives the indication may be: receiving the indication by Radio Resource Control (RRC), and/or receiving the indication by using Downlink Control Information (DCI).

A2. The at least one indication is used to allocate at least two resources, and the at least two resources are used for performing uplink transmission of at least two pieces of data.

In this embodiment, the at least two resources are resources of at least one cell, and the at least two resources may include at least one type of resources: time domain resources, time-frequency resources, beam-based time-frequency Resources, time-frequency resources based on air interface format, radio resources for terminal-to-terminal (D2D) communication, and radio resources for communication between terminals and network devices, for Orthogonal Frequency Division Multiplexing (OFDM) Radio resources, radio resources for single-carrier frequency-division multiple access (SC-FDMA), contention-based time-frequency resources. The air interface format is a parameter set of a subcarrier interval and a cyclic prefix, for example, set by a numerology parameter.

Optionally, as shown in FIG. 2, the first overlapping area in the embodiment refers to a portion corresponding to the first time domain corresponding to the overlapping area in FIG. 2, and determines that the value of the first time domain is greater than a set. The threshold may determine that the area corresponding to the first time domain is an overlapping area. The terminal device determines a first power in the first time domain of the cell 1; determines another first power in the first time domain of the cell 2; and if the first power of the cell 1 and the cell 2 corresponds to the first time domain It is greater than the maximum power, that is, the power control scenario targeted by the embodiment of the present application.

Step 102: If the at least two resources correspond to the same physical channel, and the sum of the first powers corresponding to the at least two resources in the first overlapping area is greater than the maximum power (the maximum power may be that the terminal devices overlap a maximum output power of the area, the terminal device determining a power factor of each of the at least two resources according to a priority of each of the at least two resources; wherein the at least two are based on the power factor The sum of the adjusted powers of the first power in the overlapping area is less than or equal to the maximum power, and the power factor of the high priority resource among the at least two resources is large, priority Low resources have a small power factor.

When the sum of the powers of the first overlapping area is greater than the maximum power, power adjustment (or power adjustment) is required, and the specific adjustment manner may be to expand, reduce, or remain unchanged for the first power. If the transmission power corresponding to the other resources is to be adjusted, the total transmission power does not exceed the maximum power, and the other resources may include other resources for the uplink transmission of the serving cell, or Resources of other TTI lengths of the cell for uplink transmission of the terminal device. The maximum power can also be understood as the maximum output power, such as the linear value of the UE total configured maximum output power.

Optionally, the power factor may be greater than or equal to 0. After the first power is adjusted, the terminal device may perform data transmission based on the adjusted power. The specific implementation may be:

Step 103: The terminal device separately adjusts power for each resource by using a power factor of each of the at least two resources, and sends data to the wireless access device according to the adjusted power of each resource.

Optionally, the priority of at least two resources in the embodiment of the present application may be pre-defined by the protocol, or pre-configured by the network device. In addition, the priority provided by the embodiment may be determined by using parameters of multiple dimensions, and specifically, the method may include:

The first type of resource-based transmission time interval (TTI) and/or sub-carrier spacing determines the priority of the resource, which may be:

The shorter the TTI length of the at least two resources (the length of the TTI can also be understood as the duration of the time domain resource of the resource), the higher the priority; and/or

The narrower the subcarrier spacing of the at least two resources, the higher the priority.

In this embodiment, when the priority of the TTI length and the priority of the subcarrier interval are used in combination, the priority of the TTI length may be determined first and then the priority of the subcarrier interval may be determined, and vice versa. Specifically, in the at least two resources, for a same TTI length, a resource with a narrow subcarrier spacing has a high priority, and a resource with a wide subcarrier spacing has a low priority; or in the at least two resources, for the same sub The carrier spacing, the resource with a short TTI length has a high priority, and the resource with a long TTI length has a low priority.

If a priority based on the TTI length is used in a specific application environment, as shown in FIG. 2, Cell 1 (Cell 1) and Cell 2 (Cell 2), the base station allocates uplink resources in the two cells, where the uplink resources of Cell 1 are allocated. The length of the TTI is 1 ms, and the length of the uplink resource of Cell 2 is 0.5 ms. In the overlapping area of the two uplink resources, the sum of the first powers determined by the terminal device for the two uplink transmissions is greater than the maximum output power, and power adjustment is needed to ensure the transmission power requirement. Since the TTI of the Cell 2 is short, the quality of service (QoS) of the data carried on the resource with a short TTI is generally high, so the terminal device preferentially guarantees the data transmission of the Cell 2. If there is still power remaining, the remaining power is allocated to the data transmission of Cell1 at this time. As shown in Figure 3.

The specific implementation may be that the transmission power of the first device of the terminal device is P1, where P1 is smaller than the maximum output power Pcmax, and the power is insufficient due to the uplink transmission of Cell2, that is, P1+P2 is greater than Pcmax, thereby performing power adjustment, and the transmit power of Cell1. From P1 to P1', the transmit power of Cell2 is P2, where P2+P1`=Pcmax.

Optionally, for the physical channel is a control channel, the control channel may be used to transmit channel state information (CSI)/scheduling request (SR)/hybrid automatic repeat request (HARQ). Feedback. In order to meet the traffic demand of the delay-sensitive and insensitive downlink data, the PUCCH can be divided into a short PUCCH and a long PUCCH according to the TTI length of the PUCCH, which is used for HARQ feedback, and the short PUCCH only needs to be occupied. For one or several OFDM or SC-FDMA symbols, the long PUCCH has a longer duration than the short PUCCH. For example, the number of OFDM or SC-FDMA symbols occupied in the same numerology scenario can be used to transmit CSI/ SR/HARQ feedback (delay-insensitive downlink data), if the long PUCCH and the short PUCCH are simultaneously transmitted, the power allocation of the short PUCCH is prioritized, and in the case of remaining power, the remaining power can be allocated for data transmission of the long PUCCH. . The possibilities listed below, at least meet at least one of the following:

1. HARQ feedback of short PUCCH > HARQ feedback of long PUCCH

2. CSI of short PUCCH > CSI of long PUCCH

3. SR of short PUCCH > SR of long PUCCH

4. HARQ feedback of short PUCCH > CSI of long PUCCH

5. HARQ feedback for short PUCCH > SR for long PUCCH

6. Short PUCCH SR>CSI of long PUCCH

The CSI channel state information includes at least one of the following: CQI channel quality information, used by the base station to select a modulation and coding scheme to better utilize radio resources; and a PMI precoding matrix indication for multi-antenna transmission. The RI rank (layer) indication is used in multi-antenna transmission. PTI precoding type indication for multi-antenna transmission. The HARQ feedback is used to notify the network device whether the downlink data is successfully decoded by the terminal device.

In the second type, the priority of the resource is determined by the priority of the cell corresponding to the resource. The specific implementation can be:

The at least two resources correspond to different cells, and according to the preset cell priority, the higher the priority of the cell corresponding to the resource in the at least two resources, the higher the priority of the corresponding resource.

Optionally, if the cell is divided into:

High frequency cell: the working frequency band is greater than or equal to 6 GHz;

Low frequency cell: the working frequency band is less than 6 GHz;

Unlicensed cells: Spectrum resources are shared and can also be understood as spectrum resources that can be shared with wireless guarantees (wifi). It can also be understood as a cell that needs to perform idle channel detection before transmitting data, for example, energy detection. If the energy detection is below the threshold, it is considered idle and can send data; otherwise, it is considered busy and data transmission is not possible.

Authorized cell: The spectrum resource is dedicated to the unlicensed cell.

The dividing principle may be the priority of the low frequency authorized cell > the priority of the low frequency unlicensed cell > the priority of the high frequency authorized cell > the priority of the high frequency unlicensed cell, and the priority of the cell may also be the following when comparing At least one:

1. The priority of the low frequency authorized cell is greater than the priority of the high frequency authorized cell;

2. The priority of the low frequency authorized cell is greater than the priority of the high frequency unlicensed cell;

3. The priority of the low frequency authorized cell is greater than the priority of the low frequency unlicensed cell;

4. The priority of the low frequency unlicensed cell is greater than the priority of the high frequency unlicensed cell;

5. The priority of the low frequency unlicensed cell is greater than the priority of the high frequency unlicensed cell;

6. The priority of the high frequency authorized cell is greater than the priority of the high frequency unlicensed cell;

7. The priority of the low frequency unlicensed cell is greater than the priority of the high frequency authorized cell;

8. The priority of the high frequency authorized cell is greater than the priority of the low frequency unlicensed cell.

Optionally, the priority of the cell in the embodiment of the present application may be pre-defined by the protocol, or may be pre-configured by the network device.

For example, the at least two resources include the first resource and the second resource, and the cell corresponding to the first resource is a low frequency cell; the cell corresponding to the second resource is a high frequency cell; according to the priority principle of the cell: for the same TTI length At least two resources, the priority of the low frequency cell is higher than the priority of the high frequency cell, and the priority of the corresponding first resource is higher than the priority of the second resource.

In some embodiments, the cell may also belong to a different cell group, and the cell group also has a priority. In this case, when determining the priority of the resource, the priority of the cell group may also be considered. The specific implementation may be:

The different cells belong to different cell groups, and according to the priority of the preset cell group, the higher the priority of the corresponding cell group in the at least two resources, the higher the priority of the corresponding resource.

Optionally, the priority of the cell group in the embodiment of the present application may be pre-defined by the protocol, or may be pre-configured by the network device.

The first cell group has a higher priority than the second cell group. If the first cell belongs to the first cell group, and the second cell belongs to the second cell group, the first resource corresponds to the first cell, and the second resource corresponds to the second cell. When determining the priority between the first resource and the second resource, one of the priority of the cell group or the priority of the cell may be selected for judgment, or may be simultaneously determined if the priority of the cell group and the priority of the cell are simultaneously determined. For the level conflict, a criterion may be set in advance, for example, the priority of the cell is the final result, or the priority of the cell group is the final result. Exemplarily, in a dual connectivity scenario, the first cell group is a master cell group (MCG), and the second cell group is a secondary cell group (SCG).

For example, the at least two resources include a first resource and a second resource, and the cell group corresponding to the first resource is a primary cell group; the cell group corresponding to the second resource is a secondary cell group; according to the priority principle of the foregoing cell group: For the at least two resources of the same TTI, the priority of the primary cell group is higher than the priority of the secondary cell group, and the priority of the corresponding first resource is higher than the priority of the second resource.

The third type determines the priority of at least two resources by the priority of the media access control (MAC) packet corresponding to the at least two resources. The specific implementation may be:

And the terminal device notifies the physical layer of the terminal device of the priority of the at least two resources by using a MAC layer, where a priority of the at least two resources corresponds to a MAC packet corresponding to the at least two resources.

In this embodiment, the MAC layer may be configured on the MAC layer based on the mapping relationship between the logical channel and the TTI length, and then the MAC packet obtained by the MAC packet may be prioritized by the logical channel corresponding to the data transmitted by the MAC packet or the TTI length. The level determines the priority of the MAC packet. The specific implementation can be:

The resource used for the high priority data (ie, the MAC packet) of the logical channel in the at least two resources has a higher priority than the data used by the data with the lower priority of the logical channel.

The fourth type determines the priority of the resource based on whether the resource transmits data. The specific implementation may be:

In the time domain, a second overlapping area exists in the at least two resources, and a sum of the second powers of the at least two resources in the second overlapping area is greater than a maximum power;

On the second overlapping area, the terminal device uses the adjusted power of the untransmitted data on the first overlapping area to the wireless connection for the resource that has not transmitted data in the at least two resources. The incoming device sends data.

Optionally, on the second overlapping area, the terminal device performs power adjustment on other resources including the second overlapping area except the resources that have not transmitted data among the at least two resources. That is, in the embodiment, when power adjustment is performed for at least two resources, power adjustment may be performed in units of overlapping regions; if power adjustment is performed on the second overlap region, power adjustment is performed only for resources including the second overlap region.

The specific implementation of this embodiment may be: in the second overlapping area, if the sum of the second powers of the at least two resources is greater than the maximum output power, the resources that have used the allocated power for data transmission in at least two resources are prioritized. The power allocation of the resources for data transmission is guaranteed. As for the data of the allocated power, the power is not allocated when the power adjustment is performed.

The above four resource priorities are only some implementations of the embodiment. In the specific implementation, the priority division of at least two resources may be displayed in other manners, and details are not described herein again. In addition, the foregoing priority descriptions are implemented separately, but in the specific implementation, the foregoing various priority principles may be used in combination, for example, the priority of the TTI length is combined with the priority of the subcarrier spacing; The priority of the TTI length of the resource, if the priority of the TTI length is the same; then the priority of the subcarrier spacing may be determined; or the priority of the subcarrier spacing of at least two resources may be determined first, if the subcarrier spacing is prioritized The level is the same; then the priority of the TTI length can be judged.

Optionally, when resource allocation is performed based on the foregoing priority, an unlicensed cell/HF cell may have a small TTI length and/or a subcarrier spacing is large, but the transmission may be performed. The data is not required for delay and reliability, and the transmission power may not be preferentially guaranteed, and may be equivalent to the low priority of the preset priorities.

The solution in this embodiment may be configured to set basic power corresponding to the cell group for different cell groups (that is, each base station has a basic guaranteed power), and the specific terminal device is configured according to each of the at least two resources. The priority determines the power factor of each of the at least two resources includes:

Determining, by the terminal device, a basic power of a cell group corresponding to the at least two resources;

Determining, by the terminal device, a power factor of each of the at least two resources according to a priority of each of the at least two resources and the basic power; wherein the at least two resources are based on the power factor The sum of the powers of the first power in the overlap region is less than or equal to the maximum power, and the sum of the powers corresponding to each cell group is not less than the basic corresponding to each cell group. power.

For example, the UE can perform data communication with at least two base stations. To avoid that one base station has no power to transmit, the cell group of each base station is pre-configured with a corresponding basic power, for example, the first basic power is the cell group of the primary base station. The basic guaranteed power is the basic guaranteed power of the cell group of the secondary base station. The terminal device preferentially satisfies the first basic power and the second basic power when performing power allocation in the overlapping area. For the remaining power, power allocation is performed according to the various priority principles described above.

Step 401: The terminal device determines at least two resources, where the at least two resources have a first overlapping area in the time domain, and each of the at least two resources corresponds to a first power in the first overlapping area;

Step 402: If the at least two resources correspond to at least two physical channels, and the sum of the first powers corresponding to the at least two resources in the first overlapping area is greater than a maximum power, the terminal device is configured according to the at least Determining a power factor of each of the at least two resources by a priority of each of the two resources, and/or determining, by the terminal device, a priority of a physical channel corresponding to each of the at least two resources Determining a power factor of each of at least two resources; wherein, a sum of powers of each of the at least two resources adjusted in the first power of the overlapping area is less than or equal to the power factor based on the power factor The maximum power is described, and a resource with a higher priority among the at least two resources has a larger power factor, and a resource with a lower priority has a smaller power factor.

In this embodiment, the at least two physical channels may be a PUSCH and a PUCCH. If the priority of the physical channel is associated with the priority of the at least two resources, the at least two resources include the first resource and the second resource, the first resource corresponds to the PUCCH resource, and the second resource corresponds to the PUSCH resource, and each of the first resources The sum of the power factors of the resources is not less than the sum of the power factors of each resource of the second resource. The power factor corresponding to the same channel can be determined according to the method of Embodiment 1.

Because the resources in the method of the embodiment may correspond to different physical channels, the priority of the physical channel may also be referred to when determining the priority of the resource, where the physical channel of each of the at least two resources is prioritized. The level includes: priority of the random access channel > priority of the control channel > data channel priority.

Step 403: The terminal device separately adjusts power for each resource by using a power factor of each of the at least two resources, and sends data to the wireless access device according to the adjusted power of each resource.

In this embodiment, the priority of the physical channel and the priority of the resource may be used alone or in combination. When combined, the channel priority may be determined in advance, and then the resource priority is determined; and vice versa.

Taking the channel PUCCH and the PUSCH as an example, each channel has two TTI lengths. When the priority of the physical channel is used in combination with the priority of the resource, the method provided in this embodiment can be implemented in at least two ways. Prioritization of two resources, including:

In the first method, the priority of the priority of the resource is first sorted according to the length of the TTI (the higher the priority of the TTI is, the higher the priority is). For the resources with the same TTI length, the channel priority is used. The priority of the preset physical channel is: PUCCH>PUSCH) and is sorted again (the sorted result is shown in mode 1 in FIG. 4A);

In the second mode, the priority of the physical channel is prioritized according to the priority of the physical channel (such as the priority of the preset physical channel: PUCCH > PUSCH). If multiple resources correspond to the same physical channel, Then, the TTI length (the higher the priority of the TTI is, the higher the priority) is reordered (the sorted result is shown in the second mode in FIG. 4A).

Embodiment 3

As shown in FIG. 5, the first embodiment and the second embodiment determine the priority of each resource in the physical layer. The embodiment may further determine the priority of at least two resources in the MAC layer. Methods, including:

Step 501: The terminal device determines at least two resources, where the at least two resources have a first overlapping area in the time domain, and the at least two resources each correspond to a first power in the first overlapping area;

Step 502: If the sum of the first powers corresponding to the at least two resources in the first overlapping area is greater than the maximum power, the terminal device determines the at least the priority of the at least two resources notified by the MAC layer. a power factor of each of the two resources; wherein a sum of powers adjusted by the first power of the at least two resources in the overlapping area is less than or equal to the maximum based on the power factor Power, and a resource with a higher priority among the at least two resources has a larger power factor, and a resource with a lower priority has a smaller power factor.

Step 503: The terminal device separately adjusts power for each resource by using a power factor of each of the at least two resources, and sends data to the wireless access device according to the adjusted power of each resource.

In this embodiment, the manner in which the terminal device determines the resource priority at the MAC layer may be:

B1. The terminal device performs data multiplexing and assembling the at least one MAC packet according to a mapping relationship between the pre-configured logical channel and the TTI length.

For example, logical channel 1 has 200 bytes of data and can be transmitted through TTI length 1. Logical channel 2 has 300 bytes of data and can be transmitted through TTI lengths 1 and 2. The priority of logical channel 1 is higher than the priority of logical channel 2. The base station allocates a 400-byte TTI length 1 radio resource, and the TTI length of the resource is TTI length 1. Then, the MAC layer of the terminal device performs resource allocation according to the priority of the logical channel and the TTI length of the radio resource, and the result of the allocation is as follows: logical channel 1 transmits 200 bytes of data, logical channel 2 transmits 200 bytes of data, and remaining 100 bytes of data can be left to Data transmission is only performed after the secondary base station allocates new radio resources. In addition, the base station allocates a 100-byte uplink resource with a TTI length of 2. The MAC layer of the terminal device performs resource allocation according to the priority of the radio resource and the logical channel and the TTI length. As a result of the allocation, the logical channel 2 transmits 100 bytes of data. If the radio resources of the TTI length 1 and the TTI length 2 have overlapping regions in the time domain, in the overlapping region, since the logical channel of the data transmitted by the resource of the TTI length 1 has a higher priority, the terminal device preferentially allocates the TTI length. The power of the resource of 1 allocates the power of the resource of length TTI 2 in the case of remaining power.

B2. Determine, according to data of the logical channel included in the at least one MAC packet, a power priority of the at least one MAC packet.

The physical layer of the terminal device receives the priority determined by the terminal device through the MAC layer, and performs a power adjustment operation according to the priority.

However, when reporting the power headroom report, the UE needs to report the power headroom of all cells. Since the primary base station and the secondary base station configure the number 2 cell to the UE at the same time, the reporting format of the existing power headroom report cannot distinguish the two cells, so the reporting will cause confusion to the number 2 cell, which is based on the prior art. A power control method is further provided, where the terminal device performs data communication with at least two base stations, and the method includes:

C. If the protocol data unit includes the associated uplink control information, determine the power priority of the protocol data unit or the power priority of the corresponding resource of the protocol data unit as a high priority.

The foregoing preset rules may be used in combination. For example, the terminal may determine the power priority of the protocol data unit or the power priority of the protocol data unit corresponding resource according to rules A and C, A and B, B and C or A and B and C. When the transmission power of the terminal is limited in the overlapping area, the terminal performs, according to the power priority corresponding to each protocol data unit in the at least one protocol data unit or the power priority corresponding to the physical resource of each protocol data unit.

Taking FIG. 7a and FIG. 7d as an example, two logical channels, LCH1 and LCH2, LCH1 have a priority of 1, LCH2 has a priority of 2, priority 1 is greater than 2, and LCH1 is a special logical channel, for example, LCH1 carries a URLLC ( Ultra Reliability and Low Latency Communication, ultra high priority ultra low latency data. The terminal has two resources allocated by the base station, and the resource 1 is used for transmitting the protocol data unit 1 (corresponding to TB1 in FIG. 7d), and the resource 2 is used for transmitting the protocol data unit 2 and the associated uplink control information (corresponding to TB2 in FIG. 7d). When the terminal generates the protocol data unit, the protocol data unit 1 includes the data of the LCH1 and the LCH2, and the protocol data unit 2 only includes the data of the LCH2, but at the same time, the uplink control information is included. In the overlapping area, that is, the area corresponding to the dotted line, the power is limited. Although the protocol data unit 2 follows the uplink control information, but the protocol data unit 1 contains a special logical channel with a high priority, then the priority of the protocol data unit 1 is guaranteed.
