Description

Terminal uplink resource scheduling method and device, computing equipment and computer storage medium
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method, a device, computing equipment and a storage medium for scheduling uplink resources of a terminal.
Background
With the continuous improvement of long term evolution (LongTerm Evolution, LTE) network construction and the diversified development of services, more users and services access to wireless networks. The traffic of the real-time uplink service presents a continuous rising trend, and is typically represented by real-time video services such as video live broadcast, video monitoring and the like.
In the prior art, if a terminal (UE) has no uplink data to transmit, a base station does not need to allocate uplink resources for the UE, otherwise, the uplink resources are wasted. If the UE needs to tell the base station that there is uplink data to transmit when the UE has uplink data to transmit, the base station determines whether to allocate uplink resources to the UE. The LTE base station side provides a mechanism for uplink SR (Scheduling Request ), the UE sends control information including the uplink scheduling request to the base station (eNodeB) through a physical uplink control CHannel (Physical Uplink Control CHannel, PUCCH), then the base station sends uplink scheduling grant (UL grant) to the UE according to the received SR, and allocates a small number of physical Resource Blocks (RBs) to the UE to satisfy the transmission of the UE's next buffer status report (Buffer Status Report, BSR), and when the UE reports the buffer status report to the base station, the base station can apply more uplink resources for data transmission. In order to reduce uplink scheduling delay of the base station and the UE, the base station can also use uplink pre-scheduling to schedule resources for the UE without reporting uplink scheduling requests by the UE, and the base station can send uplink scheduling grants to the UE to configure scheduling resources for the base station. And when the UE has uplink data transmission, transmitting data by using the configured scheduling resources. When the UE does not have uplink data to send, the UE also needs to send transmission filling data to the base station using the scheduling resources configured by the base station, but the terminal side has no explicit intelligent scheduling solution.
The LTE is affected by multipath fading, external interference, insufficient deep coverage and other factors, and the repeated test shows that when the UE is in the condition of poor reference signal receiving power (Reference Signal Receiving Power, RSRP), the UE cannot timely transmit uplink real-time service data in the prior art. If the existing base station side prescheduling manner is adopted, the base station frequently allocates scheduling resources for the terminal no matter the RSRP condition of the terminal, and when the RSRP is poor, the terminal increases the transmission power to transmit data, which can deteriorate the interference noise (Interference over Thermal, ioT) of the cell and the key performance indicators (Key Performance Indicators, KPI) of the network. When two terminals with poor RSRP are respectively used for uplink data transmission at two same-frequency adjacent base stations by using the resources configured by the base stations, the mutual influence is more obvious.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a flow chart of a method for scheduling uplink resources of a terminal according to an embodiment of the present invention. As shown in fig. 1, the method for scheduling uplink resources of the terminal includes:
step S11: the terminal monitors the received power of the reference signal at the position of the terminal.
In the embodiment of the present invention, before step S11, a preset difference P1, a preset figure of merit P2, a first scheduling timer, and a second scheduling timer of the reference signal received power are set, where the preset figure of merit P2 is greater than the preset difference P1.
In step S11, when the terminal performs uplink data transmission, the Reference Signal Received Power (RSRP) of the location where the terminal is located is monitored, so as to control the uplink data scheduling transmission request of the terminal by combining the actual situation of RSRP with a preset value (including a preset difference value P1 and a preset figure of merit P2).
Step S12: the terminal acquires the current uplink resource scheduling state of the terminal.
Specifically, the terminal determines whether the current uplink resource scheduling state is in a state of requesting to schedule uplink resources or a state of stopping requesting to schedule uplink resources.
Step S13: and the terminal adjusts uplink resource scheduling behavior according to the reference signal receiving power and the current uplink resource scheduling state.
In the embodiment of the present invention, if the reference signal received power is smaller than the preset difference value P1 or the reference signal received power is larger than the preset figure of merit P2, the terminal obtains the duration of the reference signal received power, and adjusts the uplink resource scheduling behavior according to the reference signal received power, the duration and the current uplink resource scheduling state; and if the reference signal received power is larger than the preset difference value P1 and smaller than the preset figure of merit P2, the terminal maintains the current uplink resource scheduling state.
When the duration time of the reference signal receiving power is acquired, if the reference signal receiving power is smaller than the preset difference value P1, the terminal starts the first scheduling timer to count time; and if the reference signal received power is larger than the preset figure of merit P2, the terminal starts the second scheduling timer to count.
In step S13, if the reference signal received power is smaller than the preset difference P1 and the duration is not smaller than the period time T1 of the first scheduling timer, the terminal stops sending the uplink resource scheduling request to the base station and buffers the data, that is, the terminal stops sending the uplink scheduling request to the base station (SchedulingRequest, SR) or the buffer status report (Buffer Status Report, BSR), and starts to buffer the local data. If the reference signal received power is smaller than the preset difference value and the duration is smaller than the cycle time of the first scheduling timer, the terminal keeps the current uplink resource scheduling state; if the reference signal received power is greater than the preset figure of merit P2 and the duration is not less than the period time T2 of the second scheduling timer, the terminal sends an uplink resource scheduling request to the base station, that is, the terminal reports an uplink SR or BSR message to the base station requesting the base station to allocate enough scheduling resources for sending the buffered data and the current real-time data. And if the reference signal received power is larger than the preset optimal value and the duration is smaller than the period time of the second scheduling timer, the terminal keeps the current uplink resource scheduling state.
The terminal maintaining the current uplink resource scheduling state specifically means that: if the terminal is in the state of requesting to schedule the uplink resource, the terminal continues to request the base station to schedule the uplink resource; if the terminal is in the state of stopping requesting to schedule the uplink resource, the terminal continues to stop requesting to schedule the uplink resource from the base station and caches the data.
For example, the reference signal received power RSRP of the terminal is greater than the preset optimal value P2 and is already in a state of starting to request to schedule uplink resources, but as the wireless environment is continuously deteriorated, the reference signal received power RSRP is smaller than the preset optimal value P2 and greater than the preset difference value P1, or is smaller than the preset difference value P1 but does not satisfy the duration time not smaller than the cycle time T1 of the first scheduling timer, i.e. does not satisfy the duration time of the reference signal received power RSRP in the cycle time T1 of the first scheduling timer is not smaller than the preset difference value P1, and the terminal still keeps reporting the uplink SR or BSR message to the base station to request to schedule resources. Until the reference signal received power RSRP is smaller than a preset difference value P1 and the duration is not smaller than the period time T1 of the first scheduling timer, stopping requesting scheduling resources by the terminal;
similarly, the reference signal received power RSRP of the terminal is smaller than the preset difference value P1 and is already in a state of stopping requesting the scheduling resources, but as the wireless environment is continuously improved, the terminal still does not report the uplink SR or BSR message to the base station to request the scheduling resources when the reference signal received power RSRP is larger than the preset difference value P1 and smaller than the preset figure of merit P2 or larger than the preset figure of merit P2 but not longer than the period time T2 of the second scheduling timer. And the terminal starts to request the scheduling resource until the Reference Signal Received Power (RSRP) is larger than a preset optimal value P2 and the duration is not smaller than the period time T2 of the second scheduling timer.
In order to ensure the continuity and integrity of the uplink real-time video data stream as much as possible, and avoid the terminal from repeatedly executing the scheduling start-stop process, the preset difference value P1 and the preset figure of merit P2 need to be reasonably set, and the terminal adjusts and corrects the preset difference value, the preset figure of merit, the first scheduling timer and the set value of the second scheduling timer of the reference signal receiving power according to the uplink resource scheduling condition. The method can be specifically preset according to an empirical value and continuously corrected in subsequent applications. It should be noted that the preset difference P1 of the reference signal received power RSRP should be smaller than the preset optimum P2 of the reference signal received power RSRP, and the first scheduling timer and the second scheduling timer may be set as required, and there is no necessary connection between the two.
The terminal uplink resource scheduling method of the embodiment of the invention is based on the wireless signal environment of the terminal side, performs terminal autonomous uplink intelligent scheduling optimization, sets a reasonable Reference Signal Received Power (RSRP) threshold and a timer at the terminal side to control uplink data scheduling sending requests of the terminal, combines the existing server caching and terminal caching technology, can effectively avoid the problem of repeated retransmission of pre-scheduled data and the problem of data packet loss caused by uplink real-time video service performed by the terminal when the Reference Signal Received Power (RSRP) is poor, improves the actual viewing experience feeling of a user, reduces interference noise (Interference over Thermal, IOT) of a base station cell, improves network key performance indexes (Key Performance Indicators, KPI) and also reduces interference to other terminals, and improves the transmission efficiency of each terminal, thereby optimizing the base station resource configuration.
The terminal monitors the received power of the reference signal at the position of the terminal; the terminal monitors the current uplink resource scheduling state of the terminal; the terminal adjusts uplink resource scheduling behavior according to the reference signal receiving power and the current uplink resource scheduling state, so that repeated retransmission or packet loss of data caused by poor reference signal receiving power can be effectively avoided, interference to other terminals can be reduced, transmission efficiency of each terminal is improved, and base station resource allocation is optimized.
