Description

Technical Field

Background

In a New Radio (NR) system of the fifth generation mobile communication technology (5th generation, 5G) of the third generation partnership project (3 GPP), the concept of BWP is introduced. The introduction of BWP, which can control the cost and power consumption of the terminal device during communication, is a key technology in 5G systems.

Detailed Description

Before describing the embodiments of the present application, some terms referred to in the embodiments of the present application are explained:

BWP: a portion of the system bandwidth. The system bandwidth may refer to the bandwidth of one carrier, and the system bandwidth may be very large, for example: which may be 200MHz or 400MHz, some terminal devices may not support such a large system bandwidth, and therefore the network device may configure BWP for the terminal, such as: a portion of the system bandwidth, 20MHz, the end devices may communicate with the network device over 20 MHz. BWP can be divided into downlink BWP (DL BWP) and uplink BWP (UP BWP), where UP BWP can be used to transmit signals from the terminal device to the network device, that is, the terminal device can send uplink signals on UL BWP; the downlink BWP may be used to transmit signals from the network device to the terminal, and the terminal device may receive downlink signals on the DL BWP. The network device may configure multiple DL BWPs and multiple UL BWPs for the terminal device, and activate (active) at least one DL BWP and activate at least one UL BWP, where the terminal device receives downlink signals, including but not limited to downlink control signaling and downlink data, sent by the network device on the activated DL BWP; the terminal device sends an uplink signal on the activated UL BWP, including but not limited to uplink control signaling, uplink data, Scheduling Request (SR), Sounding Reference Signal (SRs), Channel State Information (CSI)/Channel Quality Indication (CQI) feedback, and the like.

Here, BWP may be defined as a combination of Resource Blocks (RBs) that are consecutive within one carrier. That is, one BWP may include a plurality of RBs.

In the NR system, the bandwidth of the terminal device may be dynamically changed. For example, as shown in fig. 1, at the first time, the traffic of the terminal device is large, and the NR system may configure a large bandwidth (BWP 1: 15 MHz-40 MHz) for the terminal device; at the second moment, the traffic of the terminal device is smaller, and the NR system may configure a bandwidth (BWP 2: 10 MHz-15 MHz) smaller than BWP1 for the terminal device, where BWP2 only needs to meet the communication requirement of the terminal device; at the third time, the NR system detects wide frequency selective fading in the bandwidth of BWP1, or the resource of BWP1 is in short supply, and the NR system may configure a new bandwidth (BWP 3: 20 MHz-60 MHz) to the end device.

The terminal device only needs to adopt the center frequency point and the sampling rate of the corresponding BWP in the corresponding BWP. Moreover, each BWP may correspond to different configurations, not only different frequency points and bandwidths. For example, the subcarrier spacing, Cyclic Prefix (CP) type, synchronization signal and physical broadcast channel (SSB) period, etc. of each BWP may be configured differently to adapt to different services.

It should be noted that the technical advantages of BWP are mainly four aspects:

1. the terminal equipment does not need to support all bandwidths, only needs to meet the requirement of the lowest bandwidth, is favorable for reducing the development cost of the terminal equipment and promotes the industrial development;

2. when the traffic of the terminal equipment is smaller than a preset value, the terminal equipment can be switched to low-bandwidth operation, and the power consumption of the terminal equipment can be reduced;

3. when a new technology appears in the 5G technology, the new technology can be directly operated on a new BWP, and the forward compatibility of an NR system is ensured;

4. the network side of the NR system can dynamically configure BWP for the transmission of the service according to the needs of the service, which increases the flexibility of data transmission of the service between the terminal device and the NR system.

BWP switching: the number of BWPs that a terminal device can be configured with is limited, for example, 4. But only one BWP can be activated at a time. That is, only one BWP can be selected for data transmission at a time among the 4 BWPs. The selection or switching of BWP may be accomplished in several ways, depending on the operating rules of BWP at 38.321.

1. Activation of a BWP is indicated by a Physical Downlink Control Channel (PDCCH), such as Downlink Control Information (DCI), which carries one or more flags indicating activation of a BWP.

2. The parameter may be used to indicate activation of a BWP by a parameter indication. For example, the parameter may be a BWP-inactivity Timer (BWP-inactivity Timer).

3. Signaling via Radio Resource Control (RRC) layer. The RRC signaling may carry an identity indicating activation of a BWP.

4. Random access procedure by a medium access control bit address (MAC) entity. In the random access procedure, activation of a BWP may be indicated by signaling.

It should be noted that the BWP switching method is merely exemplary and not limited.

However, if the bandwidth of the activated BWP is too large, the BWP activated by the above-mentioned activation method will cause waste of resources; or the bandwidth of the active BWP is too small, which may affect the transmission quality of the service data between the terminal device and the network device, and thus affect the user experience. For example, if the power of the terminal device is too low, the active BWP is too large, which may result in too little remaining power after the terminal device transmits data on the active BWP, and affect the user's use. Therefore, how to select a suitable BWP from a plurality of BWPs becomes an urgent problem to be solved.

In view of the above problem, an embodiment of the present application provides a BWP determining method, including: the network device determines the data transmission quality of each BWP in a plurality of BWPs configured for the terminal device; the network equipment determines the power consumption of the terminal equipment corresponding to each BWP; the network device determines a target BWP from the plurality of BWPs based on the data transmission quality and power consumption of each BWP.

Based on the technical scheme, the network device selects the target BWP from the plurality of BWPs based on the data transmission quality of each BWP in the plurality of BWPs and the power consumption of the terminal device corresponding to each BWP. Since the data transmission quality of each BWP may be used to indicate the service data transmission quality corresponding to the BWP, the power consumption of the terminal device corresponding to each BWP may be used to characterize the power consumption of the terminal device for transmitting the service data in the BWP. In view of this, the network device may select an appropriate BWP from the BWPs for transmitting the service data based on the data transmission quality and power consumption of the BWP, that is, the network device may select an appropriate BWP from the BWPs according to the service data transmission quality of the BWP and the power consumption of the terminal device in each BWP.

It should be noted that the BWPs may be DL BWPs or UL BWPs configured for the terminal device on the network side. When the plurality of BWPs are a plurality of DL BWPs configured for the terminal device on the network side, the target BWP may be one DL BWP of the plurality of DL BWPs; when the plurality of BWPs are a plurality of UL BWPs configured for the terminal device on the network side in the communication system, the target BWP may be one UL BWP among the plurality of UL BWPs.

Fig. 4 provides a BWP determination method for an embodiment of the present application, and as shown in fig. 4, the method may include:

step 401, the network device determines the data transmission quality of each BWP in the plurality of BWPs allocated to the terminal device.

Wherein the network device may be the network device 210 in fig. 2. The terminal device may be any one of the terminal devices in fig. 2, for example, the terminal device may be the terminal device 220 or the terminal device 230 in fig. 2, without limitation.

The plurality of BWPs allocated to the terminal device may refer to a plurality of UL BWPs or a plurality of DL BWPs.

If the BWPs are DL BWPs, the network device may determine to configure the DL BWPs for the terminal device when the network device receives an access request or a service request from the terminal device. For example, after the network device detects that the terminal device moves into the coverage of the network device, or when the network device receives an access request from the terminal device, the network device may configure a plurality of DL BWPs for the terminal device and determine the data transmission quality of the plurality of DL BWPs.

If the plurality of BWPs are UL BWPs, when the network device determines to send the service data to the terminal device, it may be determined that a plurality of UL BWPs are configured for the terminal device. For example, when the network device receives a service request for the terminal device to send service data, or when the network device receives an instruction from another device (e.g., a core network device) to instruct to send service data to the terminal device, the network device may configure a plurality of UL BWPs with the terminal device and determine the data transmission quality of the plurality of UL BWPs.

The data transmission quality of BWP may also be referred to as a data transmission coefficient, an interference coefficient, etc., without limitation. The plurality of BWPs may be DL BWPs or UL BWPs.

In one possible implementation, the data transmission quality of BWP may be determined according to the sum of the priorities of the plurality of RBs of BWP. For example, for any one of a plurality of BWPs configured for a terminal device ₁ 。BWP ₁ Including a plurality of RBs. For the BWP ₁ Any one of the plurality of RBs of _i The network device may calculate the RB according to formula one _i Priority K of _i 。

Wherein r (i, t) is used to represent RB _i Data transmission rate in time slot t, R (i, t-1) is used to indicate RB _i The average data transmission rate over a number of time slots preceding time slot t. For example, RB _i The data transmission rate in the time slot t is 15M/s, and the average data transmission rate in a plurality of time slots before the time slot t is 10M/s. Then RB _i 15/10 is 1.5. Thus, the network device can be based on the aboveThe method calculates BWP ₁ Priority of each RB. E.g. BWP ₁ Including 5 RBs with priorities of 1.1, 1.5, 1.3, 0.9, 1, respectively. BWP ₁ The data transmission quality of (1.1 +1.5+1.3+1.9+ 1) is 5.8.

The data transmission rate of the plurality of RBs per BWP in the plurality of slots may be preconfigured by the network device, or may be obtained by the network device from another device, without limitation. For example, the network device may obtain the data transmission rate of multiple RBs per BWP in multiple slots from the core network device.

Step 402, the network device determines the power consumption of the terminal device corresponding to each BWP.

The power consumption of the BWP corresponding terminal device refers to the power consumption used by the terminal device to transmit data on the BWP. For example, the power of the terminal device before transmitting data is a. Terminal equipment in BWP ₁ The remaining capacity after the data is sent to the network device is B. The terminal device is in BWP ₁ The amount of power used to transmit data is A-B, i.e., BWP ₁ The power consumption of the corresponding terminal equipment is A-B.

In one example, the network device may obtain, according to the configuration information of the terminal device, an amount of power consumed by the terminal device on a preset bandwidth within a preset time. The network device may calculate the power consumption of each BWP according to the power consumed by the terminal device over the predetermined bandwidth within a predetermined time. The configuration information of the terminal device may include an amount of power consumed by the terminal device on a preset bandwidth within a preset time. The configuration information of the terminal device may further include other information of the terminal device, such as the current power of the terminal device, the total power of the terminal device, and the like, without limitation. The preset time and the preset bandwidth may be set according to needs, for example, the preset time may be 5 seconds(s), 10s, and the like, and the preset bandwidth may be 1 megabyte (M), 5M, 10M, and the like, without limitation.

For example, the network device may obtain the configuration information of the terminal device through interaction with the terminal device. For example, after receiving an access request of a terminal device, a network device may send a response message to the terminal device, where the response message carries a first instruction, and the first instruction is used to instruct the terminal device to report configuration information. Alternatively, the network device may obtain the configuration information of the terminal device from another device, for example, the other device may be a network device that establishes a communication connection with the terminal device, or a core network device, and the like, without limitation.

Wherein, the network device may calculate the power consumption of each BWP according to formula two.

Y-M-T-N formula two

Y is used to indicate power consumption of the terminal device corresponding to the BWP, M is used to indicate power consumption of the preset bandwidth, T is used to indicate preset time, and N is used to indicate bandwidth of the BWP.

For example, the amount of power consumed by the predetermined bandwidth is 500 milliampere-hour (mAh)/MHz, that is, the amount of power consumed corresponding to the bandwidth of 1MHz is 500 mAh. The preset time is 0.01h, BWP ₁ Has a bandwidth of 30 MHz. BWP ₁ The power consumption of the corresponding terminal device is 500 × 0.01 × 30 — 150 mAh.

In another possible implementation manner, the network device may also determine the power consumption of the terminal device corresponding to each BWP through interaction with the terminal device.

For example, the network device may transmit first indication information indicating a plurality of BWPs to the terminal device. For example, the first indication information may include a plurality of bits, one bit corresponding to one BWP. Bit "001" corresponds to BWP 1. Bit "010" corresponds to BWP 2. Bit "011" corresponds to BWP 3. Bit "100" corresponds to BWP 4. Of course, each BWP may also be represented in other forms, without limitation. Each BWP may also be represented by a number and/or a string of characters, for example.

After receiving the first indication information, the terminal device may calculate power consumption of the terminal device corresponding to each BWP, and report a first response message corresponding to the first indication information to the network device, where the first response message carries the power consumption of the terminal device corresponding to each BWP. The network device may determine power consumption of the terminal device corresponding to each BWP according to the first response message. Of course, the network device may also obtain the power consumption of the terminal device corresponding to each BWP in other manners, for example, obtain the power consumption with other network devices that have established communication connections with the terminal device, which is not limited.

Further, the network device may further calculate the power consumption rate of the BWP according to the power consumption of the terminal device corresponding to the BWP, the current power of the terminal device, and the total power of the terminal device.

The current power of the terminal device refers to the remaining power of the terminal device before the terminal device transmits data on the BWP. The power consumption rate of the BWP is the ratio between the remaining power of the terminal device after transmitting data on the BWP and the total power of the terminal device. The higher the power consumption rate of the BWP, the lower the power consumption for the BWP.

For example, the network device may calculate the power consumption rate of BWP according to equation three.

Wherein, X is used for representing the Power consumption rate of the BWP, Power _ begin is used for representing the current Power consumption of the terminal device, and Y is used for representing the Power consumption of the BWP. Power is used to indicate the total Power of the terminal equipment.

For example, the current power of the terminal device is 4500mAh, BWP ₁ The power consumption of (2) is 150mAh, and the total power of the terminal equipment is 10000 mAh. BWP ₁ The power consumption rate is (4500-.

When the power consumption of the BWP is calculated by the terminal device, the power consumption rate of the BWP may be calculated by the terminal device. In this case, the terminal device may transmit the power consumption rate of each BWP to the network device. Accordingly, the network device receives the power consumption rate of each BWP from the terminal device.

In step 403, the network device determines a target BWP from the BWPs according to the data transmission quality and power consumption of each BWP.

Wherein the target BWP is an active BWP of the plurality of BWPs. The target BWP is used to transfer data. For example, when the target BWP is a DL BWP, the network device may transmit data to the terminal device through the target BWP. When the target BWP is UL BWP, the terminal device may send data to the network device via the target BWP.

It should be noted that, if the target BWP is the UL BWP, the network device may send second indication information to the terminal device after determining the target BWP, where the second indication information is used to indicate the target BWP. The terminal device may transmit data to the network device on the target BWP after receiving the second indication information.

In one example, the terminal device may calculate a weight of each BWP based on the data transmission quality and power consumption rate of each BWP, and set the BWP with the largest weight as the target BWP.

For example, the terminal device may calculate the weight of each BWP according to equation four.

W represents the weight of BWP, α and β are coefficients, H is the data transmission quality of BWP, and Y is the power consumption rate of BWP. For example, α ═ 0.4, β ═ 0.3, H ═ 5.8, and Y ═ 43.5%. Then W ≈ 0.408.

Based on the technical solution of fig. 4, the network device may select the target BWP from the BWPs based on the data transmission quality of each BWP in the BWPs and the power consumption of the terminal device corresponding to each BWP. The power consumption of the terminal device corresponding to each BWP can be used to characterize the power consumption of the terminal device after the BWP sends the service data. In view of this, the terminal device may select an appropriate BWP based on its data transmission quality and its own power amount.

In one possible implementation manner of fig. 4, in order to determine the data transmission quality of the target BWP more accurately, the method provided in this embodiment of the application may further include, after transmitting data on the target BWP: the network device updates the average data transmission rate of the RBs of the target BWP.

In one example, the terminal device may update the average data transmission rate of each RB according to a preset time interval, the transmission rate of each RB in the slot t, and the average data transmission rate of each RB in a plurality of slots before the slot t.

For example, the terminal device may determine the updated average data transmission rate of the RB according to equation five.

Wherein R (i, t) is used to represent RB _i The updated average data transfer rate. T is used to represent a preset time. For example, the preset time may be set according to needs, such as a Transmission Time Interval (TTI), without limitation. r (i, t) is for RB _i Data transmission rate in time slot t, R (i, t-1) is used to indicate RB _i The average data transmission rate over a number of time slots preceding time slot t.

In another possible implementation manner of fig. 4, the method provided in the embodiment of the present application may further include: and the network device and the terminal device perform data transmission on a plurality of RBs of the target BWP.

The terminal device and the network device may perform data transmission on a preset number of consecutive RBs with the largest sum of priorities. The preset number may be set as desired.

For example, the target BWP includes N RBs. N is a positive integer. The N RB numbers are 1, 2, … …, N. The terminal device may transmit data to the network device on K RBs of the N RBs. K is a positive integer less than N.

For example, the sum of the priorities of the 1 st RB to the Kth RB is K ₁ The sum of the priorities of the 2 nd RB to the K +1 th RB is K ₂ … …. In this way, the sum of the priorities of the sets of RBs can be obtained. The network device and the terminal device may perform data transmission on a group of RBs with the largest sum of priorities among the plurality of groups of RBs.

Further, in the technical solution shown in fig. 4, step 403 may also be implemented by the following steps:

the terminal device calculates the weight of BWP based on the sum of the power consumption rate of BWP and the priority of the target group RB in BWP.

Wherein the target group RB is a group of RBs whose sum of priorities of RBs in the BWP is maximum.

Specifically, the terminal device may calculate the weight of BWP according to equation six.

Wherein, K _i For indicating the sum of the priorities of the target groups RB in BWP. The definitions of α, β and H can refer to the formula four, and are not repeated.

In another possible implementation manner of fig. 4, the method provided in the embodiment of the present application may further include:

if the current power amount of the terminal device is lower than the preset power amount, the network device may use the BWP meeting the preset condition as the target BWP.

Wherein the preset condition is used for the network device to select a target BWP matching the current power level of the terminal device from the plurality of BWPs. For example, the preset condition may include one or more of a minimum bandwidth, a bandwidth smaller than a preset bandwidth, a maximum weight, and a minimum power consumption.

It should be noted that, if the data transmission between the terminal device and the network device is performed on the first BWP at the first time, the power of the terminal device is greater than the preset power. After a period of data transmission, the remaining power of the terminal device is lower than the preset power, the network device and the terminal device may switch from the first BWP to the BWP meeting the preset condition, and perform data transmission on the BWP meeting the preset condition, so as to reduce the power consumption of the terminal device.

Based on the possible implementation manner, when the current power level of the terminal is set to be low, the network device may perform data transmission with the terminal device through the BWP meeting the preset condition. For example, the network device may transmit data on a BWP that consumes less power and has the best transmission quality to improve the user experience.

The method of fig. 4 will be described in conjunction with the communication system of fig. 2.

As shown in fig. 5, for a method for determining BWP provided in an embodiment of the present application, the method may include:

step 501 (optional), data transmission is required between the network device and the terminal device.

Wherein, data transmission is required to be carried out between the network equipment and the terminal equipment, and the method comprises the following steps: the network device needs to send data to the terminal device, or the terminal device determines to send data to the network device.

Step 502, the network device determines the data transmission quality of each BWP in the plurality of BWPs allocated to the terminal device.

Step 503, the network device determines the power consumption of the terminal device corresponding to each BWP.

Step 504, the network device determines a target BWP from the BWPs according to the data transmission quality of each BWP and the power consumption of the corresponding terminal device.

The detailed description of steps 502 to 504 may refer to steps 401 to 403 in fig. 4.

Step 505 (optional), the network device and the terminal device perform data transmission on the target BWP.

If the target BWP is a DL BWP, the data transmission between the network device and the terminal device on the target BWP means: the network device sends data to the terminal device on the target BWP, and correspondingly, the terminal device receives the data from the network device; if the target BWP is UL BWP, the data transmission between the network device and the terminal device on the target BWP means: the terminal device sends data to the network device on the target BWP, and accordingly, the network device receives the data from the terminal device.

Step 506 (optional), the network device updates the average data transfer rate of the RBs of the target BWP.

The detailed description of step 506 may refer to the first possible implementation manner of fig. 4.

Based on the technical solution of fig. 5, the network device selects a target BWP from the BWPs based on the data transmission quality of each BWP in the BWPs and the power consumption of the terminal device corresponding to each BWP. The power consumption of the terminal device corresponding to each BWP can be used to characterize the power consumption of the terminal device after the BWP sends the service data. In view of this, the network device may select an appropriate BWP based on the data transmission quality of the BWP and the power level of the terminal device.
