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 early stage of the construction of a New Radio (NR) system, the current network user and the data traffic are low, so that only a simple resource allocation mode is designed for uplink resources. Specifically, when uplink resource allocation is performed, no matter what kind of service is used by the terminal, the idle resource is queried from the starting point of the resource, that is, the idle resource is queried in the system according to a discontinuous allocation mode (marked as Type 0) and a continuous allocation mode (marked as Type 1) set by the system or a Dynamic allocation mode (marked as Dynamic, namely, dynamic switching between Type0 and Type 1), regardless of the resource Type, and the obtained idle resource is used as an alternative resource of the currently scheduled terminal; and then, when the alternative resources are further determined to meet other constraint conditions of the system (such as a resource allocation mode, constraint of calculation results of other algorithms and the like), allocating the idle resources to the currently scheduled terminal occupation. Then, the terminal determines a maximum power back-off value (Maximum power reduction, MPR) corresponding to the allocated idle resources according to a preset power back-off protocol.
The reason why the terminal performs power backoff is that, in the NR system, the peak-to-average ratio of the uplink signal increases with different magnitudes due to different uplink signal modulation schemes or uplink resource occupation schemes, so that it is specified in the power backoff protocol 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 meeting the requirements for the power amplifier design.
The MPR size has a great relationship with the uplink modulation mode adopted by the terminal and the position of the occupied idle resource, and further may also be 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 less than or equal to 100M, terminals with power capabilities of Class2 (see table 1) and Class3 (see table 2) use different uplink modulation modes and occupy different idle resources, i.e. Resource Blocks (RBs), and corresponding magnitudes of power backoff under different waveform conditions.
TABLE 1
TABLE 2
As shown in tables 1 and 2, the RB resources are divided into Edge resources (Edge RBs), external resources (Outer RBs) and internal resources (Inner RBs) according to the difference of the resource positions, and when the terminal uses different uplink modulation schemes, different MPRs are used.
Based on the above resource allocation method, no matter what service requirement the terminal side has, the network side will start searching available idle resources from the RB start position, so that the terminal performs power backoff based on the allocated idle resource position and combines with the uplink modulation method, and the following drawbacks will exist in this process:
1. when the actual service requirement of the terminal does not need to carry out power back-off, or when the power capability of the terminal is poor, or when the terminal is at the cell edge, the power back-off is forced, the transmitting power of the terminal can be further reduced, so that the quality of an uplink is poor, the service use of the terminal is affected, and the perception of a user is reduced.
2. When the terminal suitable for allocating Edge RB and Outer RB is allocated with Inner RB, system resources are blocked, so that when resources are required to be allocated in a continuous allocation mode in the follow-up process, the resource utilization rate is reduced, and the throughput of a cell is reduced or the perception of partial users is reduced.

Detailed Description
In order to reduce the influence of power backoff on system performance and ensure resource utilization rate when a terminal transmits an uplink signal, in the embodiment of the present disclosure, for different service requirements and wireless quality, the MPR used by the terminal is affected by optimizing the occupation position of uplink resources (i.e., uplink RBs) in the uplink scheduling process.
The preferred embodiments of the present disclosure will be described in detail with reference to fig. 1.
Step 101: the network side continuously receives a 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, the step 103 is executed; otherwise, step 104 is performed.
And the network side determines that the PHR continuously received reaches a preset power margin threshold value within a preset time period, and determines that the terminal is 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 in the duration T, that is, determines whether PHR > =thphr? If yes, the terminal is a non-cell edge terminal or a non-power limited terminal.
It should be noted that, before the network side determines whether the terminal is a cell edge terminal or a non-power limited terminal based on the received PHR, the network side may perform pre-determination based on an uplink estimated modulation and coding order (Modulation and Coding Scheme, 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, if the uplink estimated MCS level is a non-highest level, it needs to further determine whether the terminal is a non-cell edge terminal or a non-power limited terminal based on the received PHR, so as to complete uplink resource allocation to the terminal, otherwise, if the uplink estimated MCS level is not a non-highest level, that is, the uplink estimated MCS level is a highest level, the operation in step 105 is directly skipped.
Step 103: and the network side judges whether the uplink estimated service state of the terminal accords with a preset condition 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 the network side determines that the uplink estimated service state of the terminal accords with the preset condition when determining that the number of the uplink estimated resource blocks of the terminal is not more than the preset number threshold value according to the service requirement of the terminal.
Specifically, when determining that the number of uplink estimated resource blocks is < = a preset number threshold value, the preset number threshold value is marked as ul_rb_th, and 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 allocated subsequently, because the service with smaller number of uplink estimated resource blocks requires much less total power than the terminal with larger demand of resource blocks under the condition of ensuring the same target signal-to-noise ratio in the uplink transmission process, that is, the influence of MPR on the terminal with smaller number of uplink estimated resource blocks is small.
For example, the service requirement of the terminal is 20RB, the number of uplink estimated resource blocks is 23RB, and ul_rb_th is 30, so that it can be determined that the uplink estimated service state of the terminal meets the preset condition.
Mode 2: and the network side determines that the uplink estimated service state of the terminal accords with the preset condition when the estimated number of the uplink resource blocks of the terminal is not more than the preset number threshold value and the uplink estimated MCS level of the terminal is not less than the preset level threshold value according to the service requirement of the terminal.
Specifically, when determining the number of uplink estimated resource blocks < = ul_rb_th and the uplink estimated MCS level > = preset level threshold value, the preset level threshold value is marked as ul_mcs_th, and it is determined that the uplink estimated service state of the terminal meets the preset condition, and then two types of resources including Edge RB and Outer RB can be allocated, which is because the terminal with smaller number of uplink estimated resource blocks needs much less total power than the terminal with larger number of resource blocks needs 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 smaller number of uplink estimated resource blocks, and meanwhile, when the uplink estimated MCS level is higher, it is indicated that the terminal can compensate the loss caused by the power backoff by reducing the MCS level, increasing the number of resource blocks and ensuring the uplink service quality. Therefore, the terminal can occupy two types of resources, namely Edge RB and Outer RB, and execute corresponding non-low-power back-off.
For example, the service requirement 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=50, and ul_mcs_th=20, and the judgment condition is satisfied.
Therefore, the problem that the RB resources cannot be fully utilized due to the fact that after the Inner RB resources are occupied, the cell uplink resources are blocked can be effectively avoided for the terminals with insufficient service requirements, namely, the terminals with the number of uplink estimated resource blocks of the terminals not reaching the preset number threshold value, and meanwhile, the throughput and user perception of the cell can be improved.
Step 104: and the network side allocates uplink resources for the terminal in an internal resource block (i.e. Inner RB) to enable the terminal to execute corresponding power back-off based on the allocated uplink resources.
Specifically, when searching for available idle RBs, the network side searches for idle RBs in an internal resource block (Inner RB).
Referring to table 1 and table 2, when searching for an idle RB in the Inner RB, after determining that the RB resource is configured for the terminal based on the state of the terminal and the PHR reported by the terminal, according to the indication of the table 1 and table 2, further, according to the protocol table, the terminal is enabled to execute corresponding power backoff based on the allocated uplink resource, specifically, determines a corresponding power backoff value based on the configured RB resource, and further enables the terminal to execute 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 the terminal is determined to be a non-cell edge terminal or a non-power limited terminal, but when the uplink estimated service state of the terminal does not meet a preset condition, uplink resources are determined to be allocated to the terminal in the Inner RB.
In this way, compared with the uplink resource allocation algorithm in the prior art, the rate of the terminal can be improved, specifically, for a certain type of terminal, the power back-off value corresponding to the Inner RB is lower than that of Edge RB and Outer RB, the power back-off of the terminal is reduced, the available power is increased, the quality of the uplink is improved, and furthermore, when the quality of the uplink is poor, the power value of a single RB can be increased by reducing the number of RBs allocated to the terminal, and the power of the terminal is improved in a phase-change manner.
Step 105: and the network side allocates uplink resources for the terminal in an Edge resource block (namely Edge RB) and an external resource block (namely Outer RB), so that the terminal executes corresponding power back-off based on the allocated uplink resources.
The network side searches idle RBs in Edge RBs and Outer RBs when determining that the terminal allocates uplink resources in an Edge resource block (i.e., edge RB) and an external resource block (i.e., outer RB) based on the determination in step 102 or based on the determination performed by a combination of step 102 and optional step 103.
Referring to table 1 and table 2, when searching idle RBs in Edge RBs and Outer RBs, after determining that an RB resource is configured for a terminal based on a state of the terminal and PHR reported by the terminal, according to the instructions of table 1 and table 2, further, according to a protocol table, the terminal is enabled to execute corresponding power backoff based on the allocated uplink resource, specifically, a corresponding power backoff value is determined based on the configured RB resource, and further, the terminal is enabled to execute corresponding power backoff.
In this way, when the network side determines that the terminal has large bearing capacity for power backoff based on the uplink service state of the terminal and the PHR reported by the terminal, uplink resources allocated to the terminal are searched in Edge RB and Outer RB, so that differentiated processing aiming at different terminals can be realized, optimal selection and allocation of uplink resources are realized, the influence of resource backoff on the uplink transmission quality of the terminal is reduced, the service quality of a system is ensured, and effective utilization of resources is realized.
Further, in the above embodiment, 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, and after determining the starting position information and the length information of the RB configured to the terminal, sends the starting position information and the length information to the terminal.
