Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The plurality of the present invention means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. In addition, it should be understood that although the terms first, second, etc. may be used to describe various data in embodiments of the present invention, these data should not be limited by these terms. These terms are only used to distinguish the data from each other.
With the rapid development of global government affairs, public safety, transportation, energy, military and other industries and the rapid development of mobile internet and intelligent terminals, wireless data services are in explosive growth. On the basis of traditional voice clustering, private network industry users rapidly increase the requirements for broadband wireless data service and multimedia cluster scheduling, broadband becomes the development trend of the whole wireless communication system, and technically develops towards system IP, service diversification, data broadband and terminal multi-modularization.
The Long Term Evolution (LTE) system adopts Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input Multiple Output (MIMO) technologies as the standard for wireless network Evolution, has the advantages of large channel capacity, high spectrum utilization rate, strong anti-interference capability, high rate, low delay and the like, and can meet the requirements of a broadband trunking communication network in various aspects such as capacity, rate, spectrum efficiency and the like. A Broadband Trunking Communication (B-trunk C) system based on an LTE technology is a private network wireless technology which not only supports high-speed Broadband data transmission, but also supports multimedia Trunking dispatching application services such as voice, data, video and the like, not only supports Trunking voice, but also can realize interconnection calling, data service support, video single call and group call service support, multi-service fusion and command dispatching with an LTE Communication network and other digital Trunking Communication systems, and can meet the requirements of private network users on the Trunking Communication technology.
Generally, in an LTE system, an Evolved NodeB (eNB) receives Channel Quality Indicator (CQI) and Hybrid Automatic Repeat reQuest (HARQ) feedback information fed back by a terminal (UE); the CQI is modified according to HARQ feedback information, i.e., Acknowledgement (ACK) information or non-acknowledgement (NACK) information, and scheduling information of downlink traffic, such as a modulation scheme, a coding rate, and the like, is determined according to the CQI modification result. However, in the LTE broadband trunking communication system, the trunking group call service may be established in a connected state or an IDLE state, and when most group call users in the trunking group are in an IDLE mode (IDLE) state, the UE will neither feed back CQI nor HARQ feedback to the eNB. The scheduling information of the downlink service, such as the MCS level corresponding to multiple modulation schemes, such as QPSK and 16QAM, adopted by the shared channel for transmitting the group call data, cannot be determined according to the CQI modification result.
At present, in order to ensure the data demodulation performance of a terminal involved in a trunking group call service, a fixed and low-order MCS mode is usually adopted for scheduling the trunking group call service, so that downlink control channel resources are limited, and uplink and downlink data transmission throughput is low, which results in low trunking group call wireless transmission efficiency. In addition, such a manner cannot dynamically adapt to the wireless channel condition of the location of the terminal, nor can it dynamically adapt to the physical resource situation at the multi-group scheduling time of the base station, which further results in a small number of access to the group call Service in the cluster cell and poor Quality of Service (QoS).
Based on this, the embodiments of the present invention provide a method and an apparatus for adjusting MCS of a trunking group call service, so as to solve the problem of low wireless transmission efficiency of trunking group call in the prior art. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.
For convenience of understanding, the MCS adjustment method for trunking group call service disclosed in the embodiments of the present invention is first described in detail.
Referring to fig. 1, an embodiment of the present invention provides a method for adjusting MCS of a trunking group call service, including:
step S101, acquiring the occupancy rate of a physical downlink resource block (PRB) of a target cell; the target cell is accessed with a cluster group calling service.
In specific implementation, the downlink physical resource block PRB occupancy of the target cell may be obtained as follows:
counting the number of Physical Resource Block (PRB) occupancies allocated to all PDSCH (Physical Downlink Shared Channel, PDSCH) Channel bearer services by the target cell at every preset MCS adjustment period, for example, every 10 milliseconds, and determining the PRB occupancy of the target cell according to the ratio of the number of PRB occupancies in Downlink to the total number of PRBs that can be allocated by the target cell in all Downlink subframes and special subframes.
And step S102, comparing the occupancy rate of the downlink PRB with the occupancy rate threshold range.
In specific implementation, the total number of PRBs that can be allocated to all downlink subframes and special subframes by the target cell may be multiplied by the upper limit value and the lower limit value of the occupancy threshold range to obtain the upper limit value and the lower limit value of the occupancy number of the PRBs corresponding to the target cell; and comparing the downlink PRB occupation number with a PRB occupation number range formed by a PRB occupation number upper limit and a PRB occupation number lower limit.
Step S103, according to the comparison result, adjusting the modulation and coding strategy MCS order of the cluster group calling service.
In the embodiment of the invention, the downlink PRB occupancy rate and the occupancy rate threshold range are compared by acquiring the downlink physical resource block PRB occupancy rate of the cell, and the MCS order of the cluster group call service accessed to the cell is adjusted according to the comparison result. Compared with the mode of adopting the fixed low-order MCS, the MCS order of the cluster group calling service is dynamically adjusted according to the resource use condition of the cell, such as the downlink PRB occupancy rate, so that the base station can improve the transmission efficiency as much as possible while ensuring the QoS requirement of the cluster multi-group calling service, and further improve the group calling number accessed by the cell.
In an optional embodiment, adjusting the MCS order of the trunking group call service according to the comparison result includes: and determining that the occupancy rate of the downlink PRB is outside the occupancy rate threshold range, and adjusting the MCS order of the cluster group call service.
In specific implementation, the MCS order of the trunking group call service may be adjusted up or down once every preset MCS dynamic adjustment period according to the size relationship between the upper limit value and the lower limit value of the occupancy rate threshold range of the downlink PRB. When the Downlink PRB occupancy rate is greater than the upper limit value of the occupancy rate threshold range, which indicates that the resources of the current target cell are short, the MCS order is increased (adjusted upwards) to increase the data volume transmitted by the transmission block, and the high-order MCS is adopted to reduce the quantity of Downlink Control Information (DCI) required for transmitting the data with the same capacity in unit time, so that the data throughput is increased, and the data transmission rate and efficiency are improved; and when the occupancy rate of the downlink PRB is smaller than the lower limit value of the occupancy rate threshold range, the resource surplus of the current target cell is represented, and the MCS order is reduced (down-regulated), so that the reliability of data demodulation of the cluster group calling terminal is improved.
In another optional implementation manner, when the occupancy of the downlink PRB is outside the occupancy threshold, the MCS order may be further adjusted within an order adjustment range preset for the MCS order. That is, the adjusting the MCS level of the trunking group call service according to the comparison result includes: and when the downlink PRB occupancy rate is determined to be outside the occupancy rate threshold range and the MCS order of the cluster group calling service is determined to be within the order adjusting range, adjusting the MCS order of the cluster group calling service.
Specifically, the following embodiments can be referred to:
determining that the downlink PRB occupancy rate is smaller than the lower limit value of the occupancy rate threshold range, and when the MCS order of the cluster group call service is larger than the lower limit value of the order adjustment range, reducing the MCS order of the cluster group call service; or
And when determining that the downlink PRB occupancy rate is greater than the upper limit value of the occupancy rate threshold range and the MCS order of the cluster group call service is smaller than the upper limit value of the order adjustment range, increasing the MCS order of the cluster group call service.
In an optional implementation manner, the reducing the value of the MCS order of the trunking group call service includes: according to the downward adjustment step value, reducing the MCS order of the cluster group calling service; the reduced MCS order of the cluster group calling service is larger than or equal to the lower limit value of the order adjusting range.
The downward adjustment step value may be a preset fixed value, or may be dynamically determined according to a difference between the order of the current MCS to be adjusted and the lower limit value of the order adjustment range, for example, the downward adjustment step value is set to be a smaller value in the case that the difference is smaller; setting a directional lower adjustment step value to be a larger value under the condition that the difference value is larger; in practical applications, the fixed value, the smaller value and the larger value may be set according to practical situations, and are not limited herein.
In an optional implementation manner, the increasing the MCS order of the trunking group call service includes: increasing the MCS order of the cluster group call service according to the upward adjustment step value; the increased MCS order of the cluster group calling service is less than or equal to the upper limit value of the order adjusting range.
The upward adjustment step value may be a preset fixed value, or may be dynamically determined according to a difference between the order of the current MCS to be adjusted and the upper limit value of the order adjustment range, for example, the upward adjustment step value is set to be a smaller value in the case that the difference is smaller; setting the step value to be a larger value in the upper direction under the condition that the difference value is larger; in practical applications, the fixed value, the smaller value and the larger value may be set according to practical situations, and are not limited herein.
In an alternative embodiment, the downward adjustment step value may also be set to be greater than or equal to the upward adjustment step value.
Furthermore, on the basis of the above method, an MCS dynamic adjustment switch may be set, and a default MCS order used when the MCS dynamic adjustment switch is turned off may be configured. Under the condition that the MCS dynamic adjustment switch is turned on, the method is adopted for adjustment; and under the condition that the MCS dynamic adjustment switch is closed, scheduling the cluster group call service by adopting a default MCS order. The embodiment of the invention can meet the required scene by adopting the default MCS order in practical application through the MCS dynamic adjustment switching mechanism, and simplifies the unnecessary MCS adjustment process.
For convenience of implementation, referring to fig. 2, an embodiment of the present invention further provides another MCS adjusting method for a group call service, where the method includes:
step S201, under the condition that the community has access to the cluster group calling service, judging whether an MCS dynamic regulation switch is turned on; if not, executing step S202, if yes, executing step S203;
step S202, setting the MCS level (TruncDrbMcs) of the trunking group call service as the default MCS level.
Step S203, judging whether the MCS dynamic adjustment period is reached, if not, the MCS order is not changed; if so, step S204 is performed.
Step S204, calculating the downlink PRB occupancy rate of the cell.
Step S205, judging whether the downlink PRB occupancy rate is less than the lower limit value of the occupancy rate threshold range, and whether the MCS order (TruncDrbmcs) of the cluster group calling service is greater than the lower limit value of the order adjusting range; if yes, go to step S206; if not, step S207 is performed.
Step S206, according to the downward adjustment step value, reducing the MCS order (TruncDrbMcs) of the trunking group call service, and then ending the MCS dynamic adjustment period, where the MCS order is reduced compared with the previous MCS order.
Step S207, judging whether the occupancy rate of the downlink PRB is larger than the upper limit value of the occupancy rate threshold range, and whether the MCS order (TruncDrbmcs) of the cluster group call service is smaller than the upper limit value of the order adjusting range; if yes, go to step S208; if not, ending the MCS dynamic adjustment period, and keeping the MCS order unchanged.
Step S208, according to the upward adjustment step value, increasing the MCS order (TruncDrbMcs) of the trunking group call service, and then ending the MCS dynamic adjustment period, where the MCS order is increased compared with the previous MCS order.
Taking the final adjustment value of the MCS order as the MCS order of scheduling of all cluster group call services in the cell in the period; the above operation is performed in a loop, i.e. the MCS order is also determined in the above manner at the next MCS dynamic adjustment period.
The method provided by the embodiment of the invention can ensure that the MCS order is properly adjusted upwards when the downlink PRB resource is in shortage and is properly reduced when the downlink PRB resource is in surplus under the condition that the cluster cell or the base station meets the requirement of the cluster group call service. By dynamically adjusting the MCS of the trunking group calling service, the trunking cell or the base station can save the resource number of the downlink control information while ensuring the QoS requirement of the trunking group calling service, improve the transmission throughput of the downlink data to improve the transmission efficiency, and further improve the quantity of the trunking group calling service which is concurrently accessed in the cell.
