Detailed Description
As described in the background art, if a UE is configured with multiple SR configurations and the SRs are carried on a Physical Uplink Control Channel (PUCCH) with a spacing of two or more subcarriers, when the UE is far away from a base station, a success rate of correctly transmitting the SR carried on the PUCCH with a larger SCS to the base station may decrease (because a transmission distance of the SR carried by the PUCCH with the larger SCS is shorter), thereby causing the base station to fail to allocate Uplink resources to the UE in time and decreasing data transmission efficiency.
According to the technical scheme, the SR configuration of at least one logic channel is adjusted through the downlink signal quality, so that the adjusted SR configuration of the logic channel is matched with the current downlink signal quality, the success rate of correctly sending an uplink scheduling request triggered by the logic channel to a base station is improved when user equipment has uplink data transmission, and then the base station can allocate uplink resources to UE in time, and the data transmission efficiency is improved.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flowchart of an SR configuration adjustment method according to an embodiment of the present invention.
The SR configuration adjustment method may be used on a user equipment side, for example, executed by a user equipment, and the SR configuration adjustment method shown in fig. 1 may include the following steps:
step S101: determining the quality of a downlink signal;
step S102: and adjusting the SR configuration of at least one logic channel according to the downlink signal quality, wherein the SR configuration of the logic channel has a coverage range.
In this embodiment, the SR configuration may include a time-frequency resource where an uplink Scheduling Request (SR) occurs, and may also include a code where the SR occurs.
In an implementation, the downlink signal quality may be used to characterize the distance between the ue and the base station. When the user equipment is close to the base station, the downlink signal quality is better; when the user equipment is far away from the base station, the quality of downlink signals is poor. In step S101, the ue may determine the quality of the downlink signal, so as to obtain the distance between the ue and the base station. Specifically, the user equipment may determine the downlink signal quality by means of measurement. It should be understood by those skilled in the art that any other implementable manner may be used to determine the downlink signal quality, and the embodiment of the present invention is not limited thereto.
In this embodiment, the UE is configured with a plurality of SR configurations by the base station, and each SR configuration may have a different Subcarrier spacing (SCS), that is, a Subcarrier spacing, and thus have a different coverage. Specifically, the wider the subcarrier spacing of the SR configuration, the wider the symbol modulation bandwidth, so that the length of the symbol (symbol) is short, the smaller the coverage of the SR configuration corresponding to the SR configuration when transmitting, that is, the smaller the coverage of the SR configuration; meanwhile, the shorter the time taken for transmitting the SR corresponding to the SR configuration.
Specifically, referring to fig. 2, the circular area 2 represents the coverage of the SR configuration when the SCS is large; the circular area 1 represents the coverage that the SR configuration has when the SCS is small. The area of the circular region 1 is larger than the area of the circular region 2.
In this embodiment, since the SR configuration used by the ue depends on the logical channel triggering the SR, that is, the logical channel and the SR configuration have a mapping relationship, the SR configuration actually used by the ue can be adjusted by adjusting the mapping relationship between the logical channel and the SR configuration, so as to adjust the transmission distance or the transmission duration of the SR.
In specific implementation, since the downlink signal quality may represent a distance between the ue and the base station, and the SR configuration has a coverage, in step S102, the SR configuration of at least one Logical Channel (LCH) may be adjusted according to the downlink signal quality, so that the adjusted SR configuration of the Logical Channel matches the downlink signal quality, that is, the distance between the ue and the base station matches the coverage of the SR configuration. Specifically, when the downlink signal quality is low and the UE is far away from the base station, the coverage of the SR configuration of the adjusted logical channel is large, so that the success rate of sending the SR corresponding to the SR configuration to the base station is increased; on the contrary, when the downlink signal quality is higher, and the distance between the UE and the base station is closer, the coverage of the SR configuration of the adjusted logical channel is smaller, and the shorter the time used for SR transmission is, the faster the base station can allocate the uplink resource to the UE, so that the efficiency of transmitting the SR corresponding to the SR configuration to the base station is improved.
The embodiment of the invention adjusts the SR configuration of at least one logic channel through the downlink signal quality, so that the adjusted SR configuration of the logic channel is matched with the current downlink signal quality, the success rate of correctly sending the uplink scheduling request triggered by the logic channel to the base station is improved when the user equipment has uplink data transmission, and the base station can allocate uplink resources to the UE in time and improve the data transmission efficiency.
In a specific application scenario of the present invention, that is, in an application scenario of uplink scheduling, when the UE has an uplink data transmission requirement, the time-frequency resource location included in the adjusted SR configuration transmits the SR to the gNB through the PUCCH to request an uplink resource. After receiving the SR, the gNB issues an UpLink grant (UpLink grant), and first configures a part of resources to upload a Buffer Status Report (BSR) to the UE, so as to tell the gNB about the data amount to be transmitted. And after receiving the BSR reported by the UE, the gNB determines to allocate uplink resources to the UE according to the BSR reported by the UE, the existing resources of the gNB and other comprehensive analysis. And the UE transmits uplink data by using the uplink resource.
In an embodiment of the present invention, the SR configuration of at least one logical channel is adjusted according to a comparison result between the downlink signal quality and the set threshold.
It should be noted that, the size of the set threshold may be adaptively configured according to an actual application environment, which is not limited in this embodiment of the present invention.
Preferably, step S102 may include the steps of: and when the downlink signal quality is lower than a set threshold value, switching the SR configuration configured by the logic channel corresponding to the SR configuration with the current coverage range smaller than the set range into the SR configuration with the current coverage range larger than the set threshold value.
In a specific implementation, the set threshold and the set range are correlated. Specifically, when the downlink signal quality is a set threshold, the distance between the user equipment and the base station may be determined, and the area determined with the distance as a radius is a set range related to the set threshold.
In specific implementation, when the downlink signal quality is lower than a set threshold, the SR configuration configured by the logical channel corresponding to the SR configuration whose current coverage is smaller than the set range is switched to the SR configuration larger than the current coverage, that is, the coverage of the SR configuration after switching is larger than the coverage of the SR configuration before switching, so that the coverage of the SR configuration configured by all the adjusted logical channels is larger, thereby ensuring that the success rate of correctly sending the uplink scheduling request triggered by the logical channel to the base station is improved when the user equipment has uplink data transmission, and improving the data transmission efficiency.
For example, referring to fig. 2, when the UE moves to the edge of the gNB, the coverage of the SR configuration corresponding to the LCH1 is adjusted to change from the circular area 2 to the circular area 1, so that the transmission distance of the SR triggered by the LCH1 is further increased, and the success rate of receiving the SR by the base station is improved.
Preferably, step S102 may include the steps of: and when the quality of the downlink signal is higher than a set threshold, switching the SR configuration configured by the logic channel corresponding to the SR configuration with the current coverage range larger than the set range into the SR configuration with the current coverage range smaller than the set coverage range, wherein the set threshold is related to the set range.
In specific implementation, when the quality of the downlink signal is higher than the set threshold, the SR configuration configured by the logical channel corresponding to the SR configuration whose current coverage is larger than the set range is switched to the SR configuration smaller than the current coverage, that is, the coverage of the SR configuration after switching is smaller than the coverage of the SR configuration before switching, so that the coverage of the SR configuration configured by all the adjusted logical channels is smaller, and meanwhile, the SR transmission duration triggered by the logical channel is shorter, thereby ensuring that when the user equipment has uplink data transmission, the efficiency of correctly transmitting the uplink scheduling request triggered by the logical channel to the base station is improved, and the data transmission efficiency is improved.
For example, when the UE moves to the cell center, the SR configuration is adjusted, so that the transmission duration of the SR triggered by the logical channel is shorter, and the SR can be received by the base station faster, so that the base station can allocate uplink transmission resources faster, and the data transmission efficiency is improved.
Further, a coverage of the SR configuration after the switching is greater than or equal to a coverage of an initial SR configuration configured by the logical channel, where the initial SR configuration is an SR configuration configured by a base station when the logical channel is established.
Specifically, the base station configures an initial SR configuration for the logical channel when the logical channel is established, and the initial SR configuration has a coverage. And when the SR configuration configured by the logic channel is switched to the SR configuration smaller than the current coverage range subsequently, the coverage range of the switched SR configuration is not smaller than the coverage range of the initial SR configuration. That is to say, the SR transmission duration corresponding to the switched SR configuration is greater than or equal to the SR transmission duration corresponding to the initial SR configuration, so as to avoid seizing other data services with higher transmission time requirements, and ensure the overall call quality of the user equipment.
In another embodiment of the present invention, different SR configurations are pre-divided into a plurality of gears according to the size of their coverage areas. And adjusting the gear of the SR configuration of at least one logic channel according to the comparison result of the downlink signal quality and the set threshold.
It should be noted that, the higher the SR configuration gear is, the smaller the coverage of the SR configuration is, the higher the SR configuration gear is, the larger the coverage of the SR configuration is, and the embodiment of the present invention does not limit this.
The following description will be given by taking an example in which the higher the SR configuration gear, the smaller the coverage of the SR configuration.
Preferably, step S102 may include the steps of: and when the downlink signal quality is lower than a set threshold value, downshifting the gear of the SR configuration configured by the logic channel corresponding to the SR configuration with the gear higher than the set gear, wherein the set gear is related to the set threshold value.
In specific implementation, when the downlink signal quality is lower than a set threshold, downshifting the gear configured by the SR configured by the logic channel corresponding to the SR configuration with the gear higher than the set gear, so that the coverage area of the SR configuration configured by all the adjusted logic channels is larger, thereby ensuring that the success rate of correctly sending an uplink scheduling request triggered by the logic channel to the base station is improved when the user equipment has uplink data transmission, and improving the data transmission efficiency.
It can be understood that, if the SR configuration has a higher gear, the SR configuration has a larger coverage, and the downlink signal quality is lower than a set threshold, the gear of the SR configuration, which is configured by the logic channel corresponding to the SR configuration having a gear lower than the set gear, is shifted up.
Preferably, step S102 may include the steps of: and when the downlink signal quality is higher than a set threshold value, upshifting the gear of the SR configuration configured by the logic channel corresponding to the SR configuration with the gear lower than the set gear, wherein the set gear is related to the set threshold value.
In specific implementation, when the quality of the downlink signal is higher than a set threshold, the gear of the SR configuration configured by the logic channel corresponding to the SR configuration with the gear lower than the set gear is shifted up, so that the coverage of the SR configuration configured by all the adjusted logic channels is smaller, and meanwhile, the SR transmission duration triggered by the logic channel is shorter, thereby ensuring that when the user equipment has uplink data transmission, the efficiency of correctly transmitting the uplink scheduling request triggered by the logic channel to the base station is improved, and the data transmission efficiency is improved.
It can be understood that if the SR configuration has a higher gear, the coverage of the SR configuration is larger, and the downlink signal quality is higher than the set threshold, the gear of the SR configuration with the gear higher than the logic channel corresponding to the SR configuration of the set gear is shifted down.
Further, the plurality of gears match priorities of different SR configurations, the higher the gear, the higher the priority. In a specific implementation, the higher the gear of the SR configuration is, the shorter the transmission duration of the SR corresponding to the SR configuration is, the higher the delay requirement of the data indicating the SR is, and thus the higher the priority of the SR configuration is.
It will be appreciated that the priority is higher if the higher the SR configuration gear, the larger the SR configuration coverage, the lower the gear.
Further, the gear after the gear up shift does not exceed the gear of the initial SR configuration configured by the logical channel, where the initial SR configuration refers to an SR configuration configured by the base station when the logical channel is established. In a specific implementation, the base station configures an initial SR configuration for the logical channel when the logical channel is established, and the initial SR configuration has a gear, that is, a priority. And when the SR configuration configured by the logic channel is subsequently shifted up, the shifted-up gear does not exceed the gear configured by the initial SR configuration configured by the logic channel. That is to say, the priority of the SR configuration after the upshift does not exceed the priority of the initial SR configuration configured by the logical channel, so as to avoid preempting other data services with higher transmission time requirements, and ensure the overall call quality of the user equipment.
It is understood that if the SR configuration has a higher gear, the higher the SR configuration has, the larger the coverage of the SR configuration, the gear after downshift is not lower than the gear of the initial SR configuration configured by the logical channel.
Preferably, the SR configuration adjustment method shown in fig. 1 may further include the steps of: after the SR configuration is adjusted for the first time, in a set time, according to a comparison result of the downlink signal quality and an offset threshold, performing subsequent adjustment on the adjusted plurality of SR configurations, wherein the offset threshold is equal to the sum of the set threshold and a preset offset.
In specific implementation, in order to prevent frequent switching of SR configurations and reduce power consumption of the UE, after the SR configurations are adjusted for the first time, subsequent adjustments are performed on the adjusted SR configurations according to a comparison result between the downlink signal quality and the offset threshold within a set time. That is to say, the preset offset is added on the basis of the set threshold to form the offset threshold, so that the threshold to be compared in the next adjustment is increased, and therefore in a scene of signal change, the user equipment can be prevented from frequently adjusting the SR configuration, and unnecessary power consumption is reduced.
For example, after the SR configuration SR2 of the logic channel LCH1 is shifted down to the SR configuration SR1 because the downlink signal quality is lower than the set threshold value threshold 1, the adjusted SR configuration SR1 of the logic channel LCH1 can be shifted up to the SR configuration SR2 only when the downlink signal quality is higher than the offset threshold value, i.e., the sum of the set threshold value threshold 1 and the preset offset hysteris, within 5 seconds after the switching is completed.
It should be noted that the setting time, the setting threshold, and the preset offset may be adaptively configured according to an actual application environment, which is not limited in this embodiment of the present invention.
Fig. 3 is a flowchart of another SR configuration adjustment method according to an embodiment of the present invention.
The configuration adjustment method shown in fig. 3 may be used on the user equipment side, and the configuration adjustment method may include the following steps:
step S301: determining the quality of a downlink signal;
step S302: adjusting the SR configuration of at least one logic channel according to the downlink signal quality;
step S303: receiving an SR switching command sent by a base station, wherein the SR switching command indicates a logic channel to be switched and SR configuration after switching;
step S304: and switching the current SR configuration configured by the logic channel to be switched into the switched SR configuration according to the SR switching command.
In this embodiment, the specific implementation manner of step S301 and step S302 can refer to the related expressions of step S101 and step S102 in the embodiment shown in fig. 1, and is not described herein again.
Different from the foregoing embodiment, in step S303 and step S304, if the user equipment receives an SR switching command sent by the base station, the user equipment adjusts the SR configuration of the logical channel according to the SR switching command. The base station indicates the logical channel to be switched and the switched SR configuration in the SR switching command, and the user equipment only needs to perform a switching operation according to the SR switching command, that is, the current SR configuration configured by the logical channel to be switched is switched to the switched SR configuration.
Further, the SR switching command is configured by the base station according to uplink signal quality. That is, the base station determines a logical channel to be switched and an SR configuration after switching according to the uplink signal quality, and forms an SR switching command.
Specifically, when the uplink signal quality is lower than a set threshold, determining a logical channel corresponding to the SR configuration whose current coverage is smaller than the set range as the logical channel to be switched; and determining the SR configuration larger than the current coverage range as the switched SR configuration.
When the quality of the uplink signal is higher than a set threshold value, determining a logic channel corresponding to the SR configuration with the current coverage range larger than the set range as a logic channel to be switched; and determining the SR configuration smaller than the current coverage range as the switched SR configuration.
Alternatively, different SR configurations are pre-divided into a plurality of gears according to the size of their coverage, with higher gears having smaller coverage. When the downlink signal quality is lower than a set threshold value, determining that the logic channel corresponding to the SR configuration with the current gear higher than the set gear is the logic channel to be switched; and determining the SR configuration lower than the current gear to be the switched SR configuration. When the quality of the downlink signal is higher than a set threshold value, determining that a logic channel corresponding to the SR configuration with the current gear lower than the set gear is a logic channel to be switched; and determining the SR configuration higher than the current gear to be the switched SR configuration.
The specific process of determining the logical channel to be switched and the SR configuration after switching according to the uplink signal quality may refer to the specific implementation process of step S102, which is not described herein again.
Further, the SR switching command is transmitted and received through a Control Element (CE) of a Media Access Control (MAC). Since the SR is used by the MAC layer, the SR switching command is transmitted by using the MAC CE, so that the UE can receive the SR switching command faster, data transmission efficiency is improved, and Resource consumption can be reduced, compared with a case where the SR switching command is transmitted by using Radio Resource Control (RRC).
Fig. 4 is a schematic structural diagram of an SR configuration adjustment apparatus according to an embodiment of the invention.
