Fig. 1 is a schematic flow chart of a bandwidth portion BWP configuration method according to an embodiment of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for configuring a bandwidth portion BWP, optionally, the method may be applied to a network side device (or an access network device), where the network side device may be a Base Station (BS), and the Base Station is a device deployed in an access network to provide a wireless communication function for a UE. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of base station capable devices may vary, for example in 5G NR systems, called gndeb or gNB. As communication technology evolves, the name "base station" may change. For convenience of description, in the embodiment of the present invention, the above-mentioned devices for providing wireless communication functions for UEs are collectively referred to as network side devices.
The method comprises the following steps:
step 101, obtaining a first service resource parameter of a terminal; the first service resource parameter includes a first service rate and a first uplink transmit power.
The carrier bandwidth (Carrier Bandwidth, CB) is the operating bandwidth of the NR system, while BWP is a subset of the same, and typically, up to 4 BWP can be split in the NR system, and in the protocol version of R15, only one upstream BWP and downstream BWP are in operation, i.e. the active BWP.
BWP is defined as a combination of consecutive Resource Blocks (RBs) within one carrier. The advent of BWP allows the UE to better use a large carrier bandwidth; for a large carrier bandwidth, such as 100MHz, the bandwidth that needs to be used by a UE is often limited, and if the UE performs full bandwidth detection and maintenance in real time, the energy consumption of the terminal will be challenging, and the problem of battery endurance of the UE is aggravated. By introducing BWP, a part of bandwidth is drawn out in the whole large carrier bandwidth to carry out access and data transmission for the UE, and the UE only needs to carry out corresponding operation in the part of bandwidth configured by the system so as to reduce the monitored channel bandwidth of the UE.
Specifically, in the process of configuring BWP for UE, acquiring a first service resource parameter of the UE; the first service resource parameter is a service resource parameter of the terminal at the current moment, and the service resource parameter is used for representing the current service level of the UE, for example, the service resource parameter comprises a service rate and uplink transmitting power; optionally, the traffic rate comprises an uplink traffic rate and/or a downlink traffic rate. Optionally, taking the downlink service rate as an example, the network side device may send the traffic of the UE in a unit time as the downlink service rate of the UE.
When the network side equipment acquires the uplink transmitting power of the UE, the uplink transmitting power can be determined according to the following first formula:
P＝P0+PL+ΔF+Δp
wherein P is the uplink transmitting power; p0 is a target power value configured by network side equipment for the UE; PLi is a path loss estimated value of an uplink control signal sent by the UE to a cell to be sent, which is set by the network side, ΔF is a compensation value of the network side equipment for PUCCH with different formats, and Δp is a power control compensation value configured by the network side equipment. It will be appreciated that after determining the uplink transmit power according to the first formula, P should also be guaranteed to be less than the maximum transmit power of the UE.
Step 102, determining a target bandwidth part BWP corresponding to the first service resource parameter according to a preset bandwidth configuration rule; the bandwidth configuration rule includes a correspondence between service resource parameters and BWP.
The bandwidth configuration rule includes a correspondence between each BWP and a service resource parameter, for example, a numerical range of each BWP and each service resource parameter corresponding to each BWP, for example, a downlink service rate is taken as an example, and the correspondence includes a downlink service rate range and an uplink transmission power range corresponding to the BWP and the BWP.
Specifically, in the 5G NR system, the bandwidth may be a minimum of 5MHz (megahertz) and a maximum of 400MHz. The frequency bin of 5G NR is divided into two parts: FR1 (f <6GHz, low frequency) and FR2 (f >6GHz, high frequency, millimeter wave).
The BWP of FR1 can be configured as 5MHz,10MHz,15MHz,20MHz,25MHz,30MHz,40MHz,50MHz,60MHz,80MHz and 100MHz. The BWP of FR2 can be configured as 50MHz,100MHz,200MHz, 400MHz, etc. In the embodiment of the present invention, the BWP may be configured as one of the BWP.
The target BWP is configured as an active BWP of the terminal, step 103.
Wherein, the target BWP is configured as an active BWP of the UE, and the active BWP is the BWP in the working state at the current moment; for example, if the active BWP of the current UE is higher than the target BWP, the BWP of the UE is switched to the target BWP, so that the periodic signal of the UE is prevented from interfering with the channel environment. Specifically, the target BWP is a BWP matched with the service resource parameter of the UE, i.e., a BWP matched with the current service quality of the UE.
If the target BWP of the UE is lower than the active BWP, it indicates that the UE has a lower quality of service for the active BWP, such as a UE farther from the base station; UEs closer to the base station may transmit signals to the base station with lower uplink transmit power, while UEs farther from the base station need to transmit to the base station with higher uplink transmit power, which causes greater interference to the signal environment.
If the target BWP of the UE is higher than the active BWP, it indicates that the active BWP has a narrower bandwidth for the UE, and it is difficult to satisfy the traffic demand of the UE, and at this time, the UE should be configured with the BWP with a larger bandwidth to guarantee the traffic of the UE.
In addition, for the UE, if the current running traffic is low, only a small portion of the bandwidth is occupied; in a large bandwidth scenario, the UE needs to monitor the entire bandwidth, so that the battery has excessive consumption; therefore, matching the UE with an appropriate BWP is beneficial to battery life of the UE.
In the embodiment of the invention, a first service resource parameter of a terminal is acquired; the first service resource parameter comprises a first service rate and a first uplink transmitting power; determining a target bandwidth part BWP corresponding to the first service resource parameter according to a preset bandwidth configuration rule; the target BWP is configured as the active BWP of the terminal, so that the situation that the first BWP is higher or lower than the service requirement bandwidth of the terminal is avoided, the terminal is prevented from using higher uplink transmitting frequency to cause interference to the signal environment, and the overall channel quality is improved; meanwhile, the UE works in BWP with small bandwidth, which is beneficial to improving the battery endurance of the terminal; the embodiment of the invention solves the problem that the periodic signal of the user with low traffic of the NR system has larger interference to the channel environment in the prior art.
Optionally, in an embodiment of the present invention, the correspondence includes a traffic rate threshold and an uplink transmit power threshold corresponding to each BWP;
the step of determining the target bandwidth portion BWP corresponding to the first service resource parameter includes:
acquiring a first service rate threshold and a first uplink transmission power threshold of a first BWP, wherein the first BWP is in an activated state;
and if the first service rate and the first uplink transmitting power do not meet the corresponding relation of the first BWP in a continuous preset time period, determining a target BWP corresponding to the first service resource parameter.
That is, the corresponding relationship includes a traffic rate threshold value and an uplink transmission power threshold value corresponding to each BWP; and when determining the target BWP corresponding to the first service resource parameter, first acquiring a first service rate threshold value and a first uplink transmission power threshold value corresponding to the first BWP in an active state at the current moment of the UE in the corresponding relation so as to judge whether the service quality of the UE meets the service quality corresponding to the first BWP.
Detecting that the first service rate and the first uplink transmission power do not meet the corresponding relation of the first BWP within a preset period of time, for example, the first service rate is lower than a first service rate threshold, and the first uplink transmission power exceeds a first uplink transmission power threshold, then executing a BWP switching procedure; and in a preset time period, namely monitoring time, if the first service rate and the first uplink transmitting power do not meet the corresponding relation of the first BWP, starting a BWP switching flow, and avoiding the phenomenon of frequent BWP switching.
Optionally, in an embodiment of the present invention, the first service rate and the first uplink transmit power do not satisfy the corresponding relationship of the first BWP, including:
the first traffic rate is below a first traffic rate threshold, and the first uplink transmit power exceeds a first uplink transmit power threshold, or,
the first traffic rate is above a second traffic rate threshold and the first uplink transmit power is below a second uplink transmit power threshold.
If the first traffic rate is lower than the first traffic rate threshold, the first traffic rate threshold is the lowest traffic rate threshold corresponding to the first BWP, and the first uplink transmission power exceeds the first uplink transmission power threshold, the first uplink transmission power threshold is the highest transmission power threshold corresponding to the first BWP, which indicates that the traffic quality of the UE is lower than the traffic quality corresponding to the first BWP, and at this time, the active BWP of the UE should be switched to the BWP with smaller bandwidth to be suitable for the traffic, so as to improve the overall channel quality; meanwhile, the UE works in BWP with small bandwidth, which is beneficial to improving the battery endurance of the terminal; and the UE does not need to support all bandwidths, only needs to meet the minimum bandwidth requirement, is beneficial to the development of low-cost terminals and promotes the development of terminal industry.
The first service rate is higher than a second service rate threshold, the second service rate threshold is a high-low service rate threshold corresponding to the first BWP, the first uplink transmission power is lower than a second uplink transmission power threshold, and the second uplink transmission power threshold is a lowest transmission power threshold corresponding to the first BWP, which indicates that the service quality of the UE is higher than the service quality corresponding to the first BWP, and the UE should be switched to the BWP with a larger bandwidth at this time to meet the service requirement of the UE.
Optionally, in an embodiment of the present invention, if the first service rate and the first uplink transmit power do not satisfy the corresponding relation of the first BWP within a preset period of time, the step of determining the target BWP corresponding to the first service resource parameter includes:
if the first traffic rate is lower than a first traffic rate threshold and the first uplink transmit power exceeds a first uplink transmit power threshold, indicating that the quality of service of the UE is lower than the quality of service corresponding to the first BWP, and at this time, the active BWP of the UE should be switched to a BWP with a smaller bandwidth, the bandwidth value of the target BWP is smaller than the bandwidth value of the first BWP;
if the first traffic rate is higher than the second traffic rate threshold and the first uplink transmission power is lower than the second uplink transmission power threshold, indicating that the traffic quality of the UE is higher than the traffic quality corresponding to the first BWP, the UE should be switched to the BWP with a larger bandwidth to meet the traffic requirement of the UE, and the bandwidth value of the target BWP is larger than the bandwidth value of the first BWP.
Optionally, in an embodiment of the present invention, the step of configuring the target BWP as an active BWP of the terminal includes:
and carrying the indication information of the target BWP in Downlink Control Information (DCI) of a Physical Downlink Control Channel (PDCCH), and sending the DCI to the terminal.
Specifically, in the NR system, the BWP operation may be implemented by three modes of higher layer signaling configuration, downlink PDCCH scheduling, and timer control; in the embodiment of the invention, the downlink control information (Downlink Control Information, DCI) of the PDCCH indicates the UE to perform BWP switching, and the switching process does not need to interact with the radio resource control layer (Radio Resource Control) so as to save air interface resources.
As an example, referring to fig. 2, fig. 2 shows a specific application process of an embodiment of the present invention, mainly including the following steps:
in step 201, the ue accesses the NR system.
In step 202, the system allocates large bandwidth resources, such as BWP1, BWP2, … … BWPn, to the UE.
In step 203, the service resource parameter of the ue maintains the present status for a certain period.
Step 204, determining whether the UE rate is continuously lower than a first threshold, or whether the user channel condition is deteriorated and the uplink transmit power is continuously higher than a second threshold; if yes, go to step 205, otherwise, return to step 203.
In this example, the rate may be an uplink traffic rate and/or a downlink traffic rate, where each traffic rate corresponds to a respective preset threshold value.
In step 205, the UE is tuned to a small bandwidth BWP, such as BWP2, by PDCCH DCI.
In step 206, the service resource parameters of the ue maintain the present status for a certain period.
Step 207, determining whether the UE rate is continuously higher than a third threshold, or whether the user channel condition is deteriorated and the uplink transmit power is continuously lower than a fourth threshold; if yes, go to step 208, otherwise, return to step 206.
In step 208, the UE is tuned to a large bandwidth BWP, such as BWP3, by PDCCH DCI.
In the embodiment of the invention, a first service resource parameter of a terminal is acquired; the first service resource parameter comprises a first service rate and a first uplink transmitting power; determining a target bandwidth part BWP corresponding to the first service resource parameter according to a preset bandwidth configuration rule; the target BWP is configured as the active BWP of the terminal, so that the situation that the first BWP is higher or lower than the service requirement bandwidth of the terminal is avoided, the terminal is prevented from using higher uplink transmitting frequency to cause interference to the signal environment, and the overall channel quality is improved; meanwhile, the UE works in the BWP with small bandwidth, which is beneficial to improving the battery endurance of the terminal.
Having described the bandwidth part BWP configuration method provided by the embodiment of the present invention, the bandwidth part BWP configuration device provided by the embodiment of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 3, the embodiment of the present invention further provides a bandwidth portion BWP configuration apparatus, which may alternatively be applied to a network side device (or an access network device), where the network side device may be a base station BS, and the base station is an apparatus deployed in the access network to provide a wireless communication function for a UE. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of base station capable devices may vary, for example in 5G NR systems, called gndeb or gNB. As communication technology evolves, the name "base station" may change. For convenience of description, in the embodiment of the present invention, the above-mentioned devices for providing wireless communication functions for UEs are collectively referred to as network side devices.
The device comprises:
an acquiring module 301, configured to acquire a first service resource parameter of a terminal; the first service resource parameter includes a first service rate and a first uplink transmit power.
The carrier bandwidth is the operating bandwidth of the NR system, and BWP is a subset of the operating bandwidth, and typically, up to 4 BWP can be split in the NR system, and in the protocol version of R15, only one upstream BWP and downstream BWP are in an active state, i.e. the BWP in an active state.
BWP is defined as a combination of consecutive resource blocks within one carrier. The advent of BWP allows the UE to better use a large carrier bandwidth; for a large carrier bandwidth, such as 100MHz, the bandwidth that needs to be used by a UE is often limited, and if the UE performs full bandwidth detection and maintenance in real time, the energy consumption of the terminal will be challenging, and the problem of battery endurance of the UE is aggravated. By introducing BWP, a part of bandwidth is drawn out in the whole large carrier bandwidth to carry out access and data transmission for the UE, and the UE only needs to carry out corresponding operation in the part of bandwidth configured by the system so as to reduce the monitored channel bandwidth of the UE.
Specifically, in the process of configuring BWP for UE, acquiring a first service resource parameter of the UE; the first service resource parameter is a service resource parameter of the terminal at the current moment, and the service resource parameter is used for representing the current service level of the UE, for example, the service resource parameter comprises a service rate and uplink transmitting power; optionally, the traffic rate comprises an uplink traffic rate and/or a downlink traffic rate. Optionally, taking the downlink service rate as an example, the network side device may send the traffic of the UE in a unit time as the downlink service rate of the UE.
When the network side equipment acquires the uplink transmitting power of the UE, the uplink transmitting power can be determined according to the following first formula:
P＝P0+PL+ΔF+Δp
wherein P is the uplink transmitting power; p0 is a target power value configured by network side equipment for the UE; PLi is a path loss estimated value of an uplink control signal sent by the UE to a cell to be sent, which is set by the network side, ΔF is a compensation value of the network side equipment for PUCCH with different formats, and Δp is a power control compensation value configured by the network side equipment. It will be appreciated that after determining the uplink transmit power according to the first formula, P should also be guaranteed to be less than the maximum transmit power of the UE.
A determining module 302, configured to determine a target bandwidth portion BWP corresponding to the first service resource parameter according to a preset bandwidth configuration rule; the bandwidth configuration rule includes a correspondence between service resource parameters and BWP.
The bandwidth configuration rule includes a correspondence between each BWP and a service resource parameter, for example, a numerical range of each BWP and each service resource parameter corresponding to each BWP, for example, a downlink service rate is taken as an example, and the correspondence includes a downlink service rate range and an uplink transmission power range corresponding to the BWP and the BWP.
Specifically, in the 5G NR system, the bandwidth may be a minimum of 5MHz (megahertz) and a maximum of 400MHz. The frequency bin of 5G NR is divided into two parts: FR1 (f <6GHz, low frequency) and FR2 (f >6GHz, high frequency, millimeter wave).
The BWP of FR1 can be configured as 5MHz,10MHz,15MHz,20MHz,25MHz,30MHz,40MHz,50MHz,60MHz,80MHz and 100MHz. The BWP of FR2 can be configured as 50MHz,100MHz,200MHz, 400MHz, etc. In the embodiment of the present invention, the BWP may be configured as one of the BWP.

Wherein, the target BWP is configured as an active BWP of the UE, and the active BWP is the BWP in the working state at the current moment; for example, if the active BWP of the current UE is higher than the target BWP, the BWP of the UE is switched to the target BWP, so that the periodic signal of the UE is prevented from interfering with the channel environment. Specifically, the target BWP is a BWP matched with the service resource parameter of the UE, i.e., a BWP matched with the current service quality of the UE.
If the target BWP of the UE is lower than the active BWP, it indicates that the UE has a lower quality of service for the active BWP, such as a UE farther from the base station; UEs closer to the base station may transmit signals to the base station with lower uplink transmit power, while UEs farther from the base station need to transmit to the base station with higher uplink transmit power, which causes greater interference to the signal environment.
If the target BWP of the UE is higher than the active BWP, it indicates that the active BWP has a narrower bandwidth for the UE, and it is difficult to satisfy the traffic demand of the UE, and at this time, the UE should be configured with the BWP with a larger bandwidth to guarantee the traffic of the UE.
In addition, for the UE, if the current running traffic is low, only a small portion of the bandwidth is occupied; in a large bandwidth scenario, the UE needs to monitor the entire bandwidth, so that the battery has excessive consumption; therefore, matching the UE with an appropriate BWP is beneficial to battery life of the UE.

the first traffic rate is below a first traffic rate threshold, and the first uplink transmit power exceeds a first uplink transmit power threshold, or,
