Description
Technical Field
The present disclosure relates to the field of communications, and in particular, to a method and an apparatus for allocating uplink resources.
Background
At present, in the initial stage of the construction of a New Radio (NR) system, the current network user and data traffic is low, and therefore, only a simple resource allocation manner is designed for uplink resources. Specifically, when performing uplink resource allocation, no matter what service is used by the terminal, the terminal queries idle resources from the starting point of the resources, that is, regardless of the resource Type, according to a discontinuous allocation manner (denoted as Type0), a continuous allocation manner (denoted as Type1) or a Dynamic allocation manner (denoted as Dynamic, i.e., Dynamic switching between Type0 and Type1) set by the system, queries idle resources in the system, and uses the obtained idle resources as alternative resources of the currently scheduled terminal; and then, when the alternative resources are further determined to meet other limiting conditions of the system (such as a resource allocation mode, limitation of calculation results of other algorithms, and the like), allocating the idle resources to the currently scheduled terminal for occupation. Then, the terminal determines a Maximum Power Reduction (MPR) value corresponding to the allocated idle resource according to a preset power backoff protocol.
The reason why the terminal performs power backoff is that in the NR system, the uplink signal has a peak to peak ratio with a different amplitude due to a difference between the uplink signal modulation scheme and the uplink resource occupation scheme, and therefore, the power backoff protocol provides that, when the terminal transmits the uplink signal, a certain reduction is allowed on the basis of the maximum transmission power, that is, a certain MPR is reduced, thereby satisfying the requirement for power amplifier design.
The size of the MPR is greatly related to the uplink modulation mode adopted by the terminal and the position of the occupied idle resource, and further related to the power capability and waveform condition of the terminal. Specifically, in the 38.101 protocol, it is described that in an NR system with a system bandwidth of 100M or less, terminals with power capabilities of Class2 (see table 1) and Class3 (see table 2) use different uplink modulation schemes, and use idle resources (Resource blocks, RBs) occupying different locations, and the corresponding power backoff amplitudes under different waveform conditions.
TABLE 1
TABLE 2
As shown in table 1 and table 2, the RB resources are divided into Edge resources (Edge RBs), Outer resources (Outer RBs) and Inner resources (Inner RBs) according to different resource locations, and different MPRs are used when different uplink modulation schemes are used for the RB resources at different locations of the terminal.
Based on the resource allocation method, no matter what service requirements the terminal side has, the network side will start to search for available idle resources from the RB starting position, and make the terminal perform power backoff based on the position of the allocated idle resources in combination with the uplink modulation method, so the following defects will exist in the processing:
1. when the actual service requirement of the terminal does not need to perform power backoff, or when the power capability of the terminal itself is poor, or when the terminal is located at the edge of a cell, the power backoff is performed forcibly, which further reduces the transmission power of the terminal, thereby causing the quality of an uplink to be poor, further affecting the service use of the terminal, and reducing the user perception.
2. The terminal suitable for distributing Edge RB and Outer RB can cause system resources to be cut off when Inner RB is distributed, so that the resource utilization rate can be reduced when the resources are distributed in a continuous distribution mode in the follow-up process, and the throughput of a cell is reduced or the perception of partial users is reduced.

Detailed Description
In order to reduce the impact of power backoff on system performance and ensure resource utilization when a terminal sends an uplink signal, in the embodiment of the present disclosure, for different service requirements and radio quality, the MPR finally used by the terminal is affected by optimizing the occupied position of an uplink resource (i.e., uplink RB) in an uplink scheduling process.
The following describes in detail a preferred embodiment of the present disclosure with reference to fig. 1.
Step 101: the network side continuously receives the Power Headroom (PHR) reported by the terminal.
Step 102: the network side judges whether the terminal is a non-cell edge terminal or a non-power-limited terminal based on the received PHR, if so, step 103 is executed; otherwise, step 104 is performed.
And the network side determines that the continuously received PHR reaches a preset power margin threshold value within a preset time length, and then the terminal is determined to be a non-cell edge terminal or a non-power-limited terminal.
Specifically, the network side continuously receives the PHR sent by the terminal, and determines whether the PHR reaches the power headroom threshold value within the duration T, that is, determines whether there is a PHR? If yes, the terminal is a non-cell edge terminal or a non-power-limited terminal.
It should be noted that, before determining whether the terminal is a cell edge terminal or a non-power-limited terminal based on the received PHR, the network side may determine in advance based on an uplink estimated Modulation and Coding order (MCS) level of the terminal, specifically, may determine whether the uplink estimated MCS level of the terminal is a non-highest level according to a service requirement of the terminal, and if the uplink estimated MCS level is the non-highest level, it needs to further determine whether the terminal is the non-cell edge terminal or the non-power-limited terminal based on the received PHR to complete uplink resource allocation to the terminal, otherwise, if the uplink estimated MCS level is not the non-highest level, that is, if the uplink estimated MCS level is the highest level, directly skip to perform the operation of step 105.
Step 103: and the network side judges whether the uplink estimated service state of the terminal meets a preset condition or not according to the service requirement of the terminal, if so, the step 105 is executed, and if not, the step 104 is executed.
Optionally, after determining that the terminal is a non-cell edge terminal or a non-power-limited terminal, the network side may further determine whether the uplink estimated service state of the terminal meets a preset condition according to a service requirement of the terminal.
Specifically, the uplink estimated service state of the terminal is determined to meet the preset condition, and the following two determination modes may exist:
mode 1: and when the network side determines that the number of the uplink estimated resource blocks of the terminal is not more than a preset number threshold value according to the service requirement of the terminal, judging that the uplink estimated service state of the terminal meets a preset condition.
Specifically, when the network side determines that the number of the uplink estimated resource blocks is less than a preset number threshold, the preset number threshold is recorded as UL _ RB _ TH, it is determined that the uplink estimated service state of the terminal meets a preset condition, and two types of resources, namely Edge RB and Outer RB, can be subsequently allocated.
For example, if the traffic requirement of the terminal is 20RB, the number of uplink predicted resource blocks is 23RB, and UL _ RB _ TH is 30, it can be determined that the uplink predicted traffic status of the terminal meets the preset condition.
Mode 2: and when the network side determines that the estimated uplink resource block number of the terminal is not greater than a preset number threshold value and the estimated uplink MCS level of the terminal is not less than a preset level threshold value according to the service requirement of the terminal, judging that the estimated uplink service state of the terminal meets the preset condition.
Specifically, when the network side determines that the number of the uplink estimated resource blocks of the terminal is ═ UL _ RB _ TH and the uplink estimated MCS level > is a preset level threshold, the preset level threshold is denoted as UL _ MCS _ TH, it is determined that the uplink estimated traffic state of the terminal meets the preset condition, and then two types of resources, namely Edge RB and Outer RB, can be allocated, because the terminal with the smaller number of the uplink estimated resource blocks needs much less total power than the terminal with the larger resource block requirement under the condition of ensuring the same target signal-to-noise ratio in the uplink transmission process, that is, the MPR has little influence on the terminal with the smaller number of the uplink estimated resource blocks, and meanwhile, the uplink estimated MCS level is higher, which means that the terminal can ensure the uplink traffic quality by reducing the MCS level and increasing the resource block number when performing power backoff, make up for the loss that power backspacing brought. Therefore, the terminal can occupy two types of resources, namely Edge RB and Outer RB, and execute corresponding non-low-power backoff.
For example, when the traffic demand of the terminal is 30RB, the number of uplink estimated resource blocks is 33RB, the corresponding uplink estimated MCS level is 25, UL _ RB _ TH is 50, and UL _ MCS _ TH is 20, the determination condition is satisfied.
Therefore, the problem that RB resources cannot be fully utilized due to the fact that after Inner RB resources are occupied by terminals with low service requirements, namely terminals with the number of uplink estimated resource blocks of the terminals not reaching a preset number threshold value, the uplink resources of a cell are cut off can be effectively solved, and meanwhile throughput and user perception of the cell can be improved.
Step 104: and the network side allocates uplink resources to the terminal in an internal resource block (i.e. Inner RB), and enables the terminal to execute corresponding power backoff based on the allocated uplink resources.
Specifically, when searching for an available idle RB, the network side searches for an idle RB in an Inner resource block (Inner RB).
Referring to tables 1 and 2, when searching for an idle RB in an Inner RB, after a network side determines an RB resource configured for a terminal based on a state of the terminal and a PHR reported by the terminal, further, according to a protocol table, an indication in tables 1 and 2, the terminal is enabled to execute a corresponding power backoff based on an allocated uplink resource, specifically, a corresponding power backoff value is determined based on the configured RB resource, and then the terminal is enabled to execute a corresponding power backoff.
In the embodiment of the disclosure, when the terminal is determined to be a cell edge terminal or a power-limited terminal, or when the terminal is determined to be a non-cell edge terminal or a non-power-limited terminal but the uplink estimated service state of the terminal does not meet a preset condition, it is determined to allocate uplink resources to the terminal in an Inner RB.
In this way, compared with an uplink resource configuration algorithm in the prior art, the rate of the terminal is increased, specifically, for a terminal of a certain type, if the power backoff value corresponding to the Inner RB is lower than that of the Edge RB and the Outer RB, the power backoff of the terminal is reduced, the usable power is increased, the quality of an uplink is increased, and when the quality of the uplink is poor, the power value of a single RB is increased by reducing the number of RBs allocated to the terminal, so that the power of the terminal is increased in a phase-changing manner.
Step 105: and the network side allocates uplink resources to the terminal in an Edge resource block (namely Edge RB) and an external resource block (namely Outer RB), and the terminal is enabled to execute corresponding power backoff based on the allocated uplink resources.
The network side searches for an idle RB in an Edge RB and an Outer RB when determining that the terminal allocates an uplink resource in the Edge resource block (i.e., Edge RB) and the Outer resource block (i.e., Outer RB) based on the determination of step 102 or based on the determination made by combining step 102 and optional step 103.
Referring to tables 1 and 2, when searching for an idle RB in Edge RBs and Outer RBs, after determining, by a network side, an RB resource configured for a terminal based on a state of the terminal and a PHR reported by the terminal, further, according to the instructions of a protocol table, tables 1 and 2, the terminal is made to execute a corresponding power backoff based on an allocated uplink resource, specifically, a corresponding power backoff value is determined based on the configured RB resource, and then the terminal is made to execute a corresponding power backoff.
In this way, when the network side determines that the terminal has a large power backoff bearing capacity based on the uplink service state of the terminal and the PHR reported by the terminal, the network side searches and allocates uplink resources to the terminal in the Edge RB and the Outer RB, so that differentiated processing for different terminals can be realized, optimal selection and allocation of the uplink resources are realized, the influence of resource backoff on the uplink transmission quality of the terminal is reduced, the service quality of the system is ensured, and effective utilization of the resources is realized.
Further, in the above embodiment, no matter the network side searches for available uplink resources in the Inner RB or searches for available uplink resources in the Edge RB and the Outer RB, the network side sends the start position information and the length information of the RB configured to the terminal after determining the start position information and the length information of the RB.
