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) having 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 having a larger SCS to the base station may decrease (because a transmission distance of the SR carried by the PUCCH having 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.
In the technical scheme of the invention, the user equipment receives the SR switching command and adjusts the SR configuration of the logical channel according to the indication of the SR switching command, so that the success rate of correctly sending the uplink scheduling request triggered by the switched SR configuration to the base station through the logical channel to be switched is improved, and the base station can allocate uplink resources for UE in time and improve the data transmission efficiency.
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 the user equipment side, e.g., performed by the user equipment. The SR configuration adjustment method shown in fig. 1 may include the steps of:
step S101: 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 S102: 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 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 this embodiment, a User Equipment (UE) is configured with multiple SR configurations by a base station, and the multiple SR configurations have different Subcarrier spacings (SCS), that is, Subcarrier spacings, and thus have different coverage ranges. Specifically, the wider the subcarrier spacing of the SR configuration, the wider the symbol modulation bandwidth, so the shorter the symbol (symbol) length is, the smaller the coverage area of the SR configuration corresponding to the SR configuration when transmitting, that is, the smaller the coverage area of the SR configuration; meanwhile, the shorter the time taken for transmitting the SR corresponding to the SR configuration.
Since the SR configuration used by the ue depends on a Logical Channel (LCH) triggering the SR, that is, a mapping relationship exists between the Logical Channel and the SR configuration, 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 a specific implementation, in step S101, the ue receives an SR handover command sent by the base station. The SR switching command may indicate a logical channel and an SR configuration that need to be adjusted, that is, a logical channel to be switched and an SR configuration after switching. Specifically, the logical channel to be switched may be a part of logical channels of the user equipment, or may be all logical channels.
In a specific implementation, in step S102, the user equipment may operate according to an instruction of the SR switching command, and switch a current SR configuration configured by a logical channel to be switched to the switched SR configuration. That is to say, the logical channel to be switched is currently configured with a current SR configuration, and the current SR configuration may be an SR configuration configured by the base station when the logical channel to be switched is established, or may be an SR configuration after switching. After the adjustment, the logical channel to be switched is configured with the switched SR configuration.
For example, the logical channel to be switched indicated by the SR switching command is LCH1 and the switched SR configuration is SR2, and the current SR configuration configured by LCH1 is SR 1. The UE switches the SR configuration configured by the LCH1 from SR1 to SR2 upon receiving the SR switching command.
The user equipment of the embodiment receives the SR switching command and adjusts the SR configuration of the logical channel according to the indication of the SR switching command, so that the success rate that the uplink scheduling request triggered by the switched SR configuration is correctly sent to the base station via the logical channel to be switched is improved, and then the base station can allocate uplink resources to the UE in time, thereby improving the data transmission efficiency.
It should be understood by those skilled in the art that the UE in this embodiment already uses the maximum transmission power, that is, the SR configuration may be adjusted by using the SR configuration adjustment method in this embodiment when the coverage of the current SR configuration cannot be increased by increasing the transmission power of the UE.
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 an SR to a base station (gNB) through a PUCCH to request an uplink resource. By using the adjusted SR configuration, it can be ensured that the gNB receives the SR, and transmits an UpLink grant (UpLink grant) in the following. The gNB first allocates a portion of resources to the UE to upload a Buffer Status Report (BSR) to tell the gNB the amount of data to transmit. 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.
Preferably, the SR switching command is configured by the base station according to uplink signal quality. Specifically, the uplink signal quality may represent a distance between the user equipment and the base station, and the SR configuration has a coverage, so that the base station may configure the SR switching command according to the uplink signal quality, so that the SR configuration of the logical channel adjusted by the UE according to the SR switching command matches the uplink signal quality, that is, the distance between the user equipment and the base station matches the coverage of the SR configuration. Specifically, when the uplink signal quality is low and the UE is far away from the base station, the coverage of the switched SR configuration is large, so that the success rate of sending the SR corresponding to the switched SR configuration to the base station is increased; on the contrary, when the uplink signal quality is higher and the UE is closer to the base station, the coverage of the SR configuration after switching is smaller, and the shorter the time taken for transmitting the SR corresponding to the SR configuration after switching is, the base station can allocate the uplink resource to the UE more quickly, so that the efficiency of transmitting the SR corresponding to the SR configuration to the base station is improved.
Therefore, after the adjustment of the step S101 and the step S102, SR configurations of all logical channels of the user equipment are matched with the quality of the uplink signal, and thus when the quality of the uplink signal is low, it can be ensured that the success rate of SR transmission to the base station is increased; when the uplink signal quality is high, the time used for SR transmission is short, and the base station can allocate uplink resources to the UE more quickly, thereby further improving the data transmission efficiency.
Preferably, the SR switching command is received through a Media Access Control (MAC) Control Element (CE). 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, the data transmission efficiency is improved, and the Resource consumption is reduced, compared with the case where the SR switching command is transmitted by using Radio Resource Control (RRC) signaling.
In an embodiment of the present invention, different SR configurations are pre-divided into a plurality of shift positions according to the size of the coverage area, and the higher the shift position is, the smaller the coverage area is. Further, the plurality of gears match priorities of different SR configurations, the higher the gear, the higher the priority.
Further, the shift of the SR configuration after switching does not exceed the shift of the initial SR configuration configured by the logical channel to be switched, where the initial SR configuration is the SR configuration configured by the base station when the logical channel to be switched is established. In a specific implementation, when the logical channel is established, the base station configures an initial SR configuration for the logical channel, and the initial SR configures a gear, that is, has a priority. And when the SR configuration configured by the logic channel to be switched is switched subsequently, the switched gear does not exceed the gear of the initial SR configuration configured by the logic channel to be switched. That is to say, the priority of the SR configuration after switching 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.
In this embodiment, if the user equipment does not receive the SR switching command, the SR configuration may be adjusted according to the downlink signal quality.
Preferably, the method shown in fig. 1 may further comprise the steps of: if the SR switching command is not received, determining the quality of a downlink signal; 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.
Further, when the downlink signal quality is lower than a set threshold, downshifting the gear of the SR configuration configured by the logic channel corresponding to the SR configuration having the gear higher than the set gear, where the set gear and the set threshold are related. 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.
In a specific implementation, the set gear and the set threshold are correlated. Specifically, when the downlink signal quality is the set threshold, the distance between the user equipment and the base station may be determined, and the rank corresponding to the coverage range determined by using the distance as a radius is the set rank related to the set threshold.
Further, when the quality of the downlink signal is higher than a set threshold, the shift of the SR configuration configured by the SR configuration corresponding to the SR configuration having the shift lower than the set shift is shifted up, where the set shift and the set threshold are related. 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.
In an application scenario of the invention, when the UE moves to a cell edge, the transmission power of the UE may be first adjusted up, and when the transmission power reaches the maximum transmission power, the shift of the SR configuration configured by the logic channel corresponding to the SR configuration with the shift higher than the set shift is shifted down; when the UE moves to the center of the cell, the gear of the SR configuration corresponding to the logic channel configured by the SR configuration with the gear lower than the set gear is shifted up to meet the requirement of data priority, and then the transmitting power of the UE can be adjusted down.
Further, the gear after the up-shifting does not exceed the gear of the initial SR configuration configured by the logical channel, where the initial SR configuration refers to the 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 to be switched is subsequently shifted up, the shift after the shift up does not exceed the shift of the initial SR configuration configured by the logic channel to be switched. 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.
In another embodiment of the invention, different SR configurations are divided into a plurality of gears in advance according to the size of the coverage area, and the coverage area is larger as the gears are higher. The plurality of gears match priorities of different SR configurations, the lower the gear, the higher the priority.
In this embodiment, when the downlink signal quality is lower than the set threshold, the shift of the SR configuration configured by the SR configuration corresponding to the SR configuration having the shift lower than the set shift is shifted up. And when the downlink signal quality is higher than a set threshold value, downshifting the gear configured by the SR corresponding to the logic channel configured by the SR configuration with the gear higher than the set gear. In addition, the gear after the downshift is not lower than the initial SR configured gear configured by the logic channel.
Further, after the SR configuration is adjusted for the first time, within a set time, the adjusted SR configurations are subsequently adjusted according to a comparison result between the downlink signal quality and an offset threshold, where the offset threshold is equal to a 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. 2 is a flowchart of another SR configuration adjustment method according to an embodiment of the present invention.
The SR configuration adjustment method shown in fig. 2 may be used on the base station side, for example, performed by the base station. The SR configuration adjustment method may include the steps of:
step S201: configuring an SR switching command, wherein the SR switching command indicates a logic channel to be switched and SR configuration after switching;
step S202: and sending the SR switching command to user equipment.
In step S201, the base station configures an SR switching command to indicate a logical channel to be switched and an SR configuration after switching. It is to be understood that step S201 is performed on the premise that the UE has used the maximum transmit power.
Further, in step S202, the base station sends an SR switching command to the user equipment, so that the user equipment adjusts the SR configuration, thereby improving the success rate of SR transmission to the base station.
Preferably, step S201 may include the steps of: and configuring the SR switching command according to the quality of the uplink signal.
In the foregoing embodiment, the UE may adjust the SR configuration according to the downlink signal quality. In this embodiment, the base station may configure the logical channel to be switched and the SR configuration after switching according to the uplink signal quality, and notify the UE to execute the configuration. It can be understood that the base station may determine the uplink signal quality in any implementable manner, and the embodiment of the present invention is not limited thereto.
Preferably, the different SR configurations are divided into a plurality of gears in advance according to the size of the coverage area, and the coverage area is smaller as the gears are higher.
Further, configuring the SR switching command according to uplink signal quality may include the steps of: when the uplink signal quality is lower than a set threshold, if the user equipment uses the maximum transmitting power, determining that a logical channel corresponding to the SR configuration with a gear higher than a set gear is the logical channel to be switched, wherein the set gear is related to the set threshold; determining that the SR configuration of the gear position is lower than the SR configuration configured by the logic channel to be switched.
Further, configuring the SR switching command according to uplink signal quality may include the steps of: when the quality of the uplink signal is higher than a set threshold value, determining that a logical channel corresponding to an SR configuration with a gear lower than a set gear is the logical channel to be switched, wherein the set gear is related to the set threshold value; determining that the SR configuration of the gear position is higher than the SR configuration configured by the logic channel to be switched.
Through the embodiment of the invention, when the uplink signal quality is lower than the set threshold value, the UE is instructed to downshift the SR configured gear of the logic channel corresponding to the SR configuration with the gear higher than the set gear, so that the coverage range of the SR configuration configured by all the adjusted logic channels is larger, the success rate that an uplink scheduling request triggered by the logic channel is correctly sent to the base station is improved when the user equipment has uplink data transmission, and the data transmission efficiency is improved. When the uplink signal quality is higher than the set threshold value, the UE is instructed to shift up the gear configured by the SR corresponding to the SR configuration with the gear lower than the set gear, so that the coverage range of the SR configuration configured by all the adjusted logic channels is smaller, and meanwhile, the SR sending duration triggered by the logic channels is shorter, thereby ensuring that the efficiency of correctly sending an uplink scheduling request triggered by the logic channels to the base station is improved when the user equipment has uplink data transmission, and improving the data transmission efficiency.
Preferably, the SR configuration adjustment method shown in fig. 2 may further include the steps of: and after the first configuration is finished, configuring the next SR switching command according to the comparison result of the uplink signal quality and the offset threshold within a set time, wherein the offset threshold is equal to the sum of the set threshold and a preset offset.
In another variation of the present invention, different SR configurations are pre-divided into multiple gears according to the size of their coverage area, and the lower the gear, the smaller the coverage area.
Configuring the SR switching command according to uplink signal quality may include the steps of: when the uplink signal quality is lower than a set threshold, if the user equipment uses the maximum transmitting power, determining that a logical channel corresponding to SR configuration with a gear lower than a set gear is the logical channel to be switched, wherein the set gear is related to the set threshold; determining that the SR configuration of the gear position is higher than the SR configuration configured by the logic channel to be switched.
