Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to an uplink authorization method and device, and a computer storable medium. Background Art

[0002] In the related technology, in the uplink service scheduling process of 4G and 5G networks, when a terminal has a data transmission requirement, it first sends a Scheduling Request (SR) message to the base station to request resources for sending uplink data. After receiving the SR message, the base station sends an uplink authorization message to the terminal in response to the SR message of the terminal.

[0003] To avoid uplink interference and congestion, the base station randomly configures different SR sending offsets for the terminal. That is, the base station randomly configures different times for the terminal to send SR messages to the base station. Summary of the invention

[0004] In the related technology, since the base station randomly configures different times for sending scheduling request messages to the base station for the terminal, the order in which the terminal sends SR messages is inconsistent with the actual order in which the uplink service data arrives at the terminal. Based on this, the related technology will cause the uplink service data sending demand generated earlier. Due to different SR offsets, the actual sending order of its SR messages may also be delayed, and the order in which the terminal receives the uplink authorization message is also delayed, which leads to low uplink authorization efficiency and long uplink service data sending delay.

[0005] In view of the above technical problems, the present disclosure proposes a solution, which can improve the uplink authorization efficiency and reduce the uplink service data transmission delay.

[0034] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0035] Figure 1 is a flowchart illustrating an uplink authorization method according to some embodiments of the present disclosure.

[0036] like Figure 1 As shown, the uplink authorization method includes: step S110, in response to receiving a scheduling request message from the current terminal, determining a terminal belonging to the same association group as the current terminal as a candidate association terminal; step S120, selecting a target association terminal from the candidate association terminals; and step S130, simultaneously sending a corresponding uplink authorization message to the current terminal and the target association terminal. Terminals in the same association group are associated. For example, an uplink authorization message corresponding to the current terminal is sent to the current terminal, and an uplink authorization message corresponding to the target association terminal is simultaneously sent to the target association terminal. In some embodiments, the uplink authorization method is performed by a base station.

[0037] In the above embodiment, by selecting a target associated terminal from terminals belonging to the same associated group as the current terminal, and sending corresponding uplink authorization messages to the current terminal and the target associated terminal at the same time, the time when the target associated terminal receives the uplink authorization message is advanced, thereby improving the uplink authorization efficiency and reducing the uplink service data transmission delay.

[0038] In step S110, in response to receiving a scheduling request message from the current terminal, a terminal belonging to the same association group as the current terminal is determined as a candidate association terminal. Terminals in the same association group have association.

[0039] In some embodiments, determining that the current terminal belongs to a terminal in the same association group as a candidate association terminal may be implemented in the following manner.

[0040] First, determine the association group to which the current terminal belongs.

[0041] Then, other terminals in the association group where the current terminal is located are determined as candidate association terminals.

[0042] In some embodiments, the uplink authorization method further includes the following steps. Before receiving the scheduling request message from the current terminal, the multiple terminals are divided into one or more association groups according to at least one of the functions, geographical locations, and service characteristics of the multiple terminals. The terminals in the same association group are associated in at least one aspect of the functions, geographical locations, and service characteristics. For example, the multiple terminals are terminals in a 4G network or a 5G network. The multiple terminals include the current terminal.

[0043] In some embodiments, terminals that meet at least one of the following conditions: the terminals have the same function, the distance between their geographical locations is less than a distance threshold, and the similarity between their service characteristics is less than a similarity threshold, can be grouped into the same association group.

[0044] Figure 2 is a schematic diagram showing the division of association groups according to some embodiments of the present disclosure.

[0045] like Figure 2 As shown, multiple terminals UE11, UE12, UE21-UE29 are divided into three association groups, including a first association group, a second association group and a third association group.

[0046] In some embodiments, both UE11 and UE12 are control terminals, that is, they have control functions. UE11 and UE12 are divided into a first association group. The first association group is, for example, called a control association group.

[0047] In some embodiments, UE21-UE25 are all forwarding terminals, that is, they have a forwarding function. UE21-UE25 are divided into a second association group. The second association group is, for example, called forwarding association group 1.

[0048] In some embodiments, UE26-UE29 are all forwarding terminals and are divided into a third association group. The third association group is called forwarding association group 2, for example.

[0049] return Figure 1 In step S120, a target associated terminal is selected from the candidate associated terminals.

[0050] In some embodiments, the target association terminal is selected from the candidate association terminals according to at least one of the time when the candidate association terminal sends its corresponding scheduling request message and the characteristic information of the candidate association terminal. For example, the characteristic information of the candidate association terminal is attribute characteristic information. In some embodiments, the attribute characteristic information of the candidate association terminal includes the priority of the candidate association terminal, etc.

[0051] In some embodiments, the target association terminal can be selected from the candidate association terminals according to at least one of the time when the candidate association terminal sends its corresponding scheduling request message and the characteristic information of the candidate association terminal in the following manner: the candidate association terminal that sends the scheduling request message later than the current time is selected as the target association terminal.

[0052] In some embodiments, the target association terminal may be selected from the candidate association terminals according to at least one of the time when the candidate association terminal sends its corresponding scheduling request message and the characteristic information of the candidate association terminal in the following manner: a candidate association terminal that sends a scheduling request message later than the current time and whose time interval with the current time is greater than a preset time interval is selected as the target association terminal.

[0053] In some embodiments, the target association terminal may be selected from the candidate association terminals according to at least one of the time when the candidate association terminal sends its corresponding scheduling request message and the characteristic information of the candidate association terminal in the following manner: a candidate association terminal that sends a scheduling request message later than the current time and has a priority higher than a preset priority is selected as the target association terminal.

[0054] In step S130, a corresponding uplink authorization message is sent to the current terminal and the target associated terminal at the same time.

[0055] Figure 3 is a schematic diagram illustrating an uplink authorization method according to some embodiments of the present disclosure.

[0056] In some embodiments, after receiving a scheduling request message from any terminal in the associated group, the base station sends uplink grant information to all associated terminals in the group. The scheduling request message is denoted as SR.

[0057] For example, UE1, UE2 and UE3 are in the same associated terminal group. Figure 3 As shown, the uplink data ULData1, ULData2 and ULData3 of UE1, UE2 and UE3 arrive at the terminal at time t1, t2 and t3 respectively.

[0058] Taking UE2 sending SR2 first at t4 as an example, after receiving SR2 from UE2, the base station determines that UE1 and UE3 are in the same associated terminal group as UE2, and the SR sending times (t6 and t7) of UE1 and UE3 have not arrived. The base station sends an uplink grant message UL Grant2 to UE2 at t5, and sends uplink grant messages UL Grant1 and UL Grant3 to UE1 and UE3 respectively.

[0059] In the above embodiment, UE1 and UE3 receive their respective uplink authorization messages in advance, which reduces the data transmission delay compared to the conventional process of continuing to wait for SR. For example, the delay of UE1 receiving the uplink authorization is reduced by (t8-t5), and the delay of UE3 receiving the uplink authorization is reduced by (t9-t5).

[0060] Figure 4 It is a schematic diagram showing an uplink authorization method according to some other embodiments of the present disclosure.

[0061] In some embodiments, after receiving a scheduling request message from any terminal in the associated group, the base station selectively sends uplink authorization information to some associated terminals in the group based on pre-set conditions.

[0062] Taking UE1, UE2 and UE3 in the same associated terminal group as an example, the uplink data ULData1, ULData2 and ULData3 of UE1, UE2 and UE3 arrive at the terminal at time t1, t2 and t3 respectively.

[0063] Taking the example that UE2 first sends SR2 at t4, after receiving SR2 from UE2, the base station determines that UE1 and UE3 are in the same associated terminal group as UE2, and the base station determines that within the time interval T after sending the uplink authorization message UL Grant2 to UE2 at t5, UE1 will send SR1 at t6, while the SR3 sending time t7 of UE3 is outside the time interval T.

[0064] At t5, the base station sends an uplink grant message UL Grant2 to UE2, and simultaneously sends UL Grant3 to UE3.

[0065] In the above embodiment, UE3 receives the uplink grant in advance, which reduces the data transmission delay compared to the conventional process of continuing to wait for SR. The delay of UE3 receiving the uplink grant is reduced by (t9-t5). UE1 continues to wait and sends SR1 at t6.

[0066] Figure 5 is a schematic diagram showing an uplink authorization method according to some further embodiments of the present disclosure.

[0067] In some embodiments, after receiving the scheduling request SR information of any terminal in the associated group, the base station selectively sends uplink grant information to some associated terminals in the group based on the associated terminal feature information.

[0068] For example, UE1, UE2 and UE3 are in the same associated terminal group. Uplink data of UE1, UE2 and UE3 arrive at the terminal at time t1, t2 and t3 respectively.

[0069] Taking UE2 sending SR2 first at t4 as an example, after receiving SR2 from UE2, the base station determines that UE1 and UE3 are in the same associated terminal group as UE2 and the SR sending times (t6 and t7) of UE1 and UE3 have not arrived, but UE3 has a high priority and UE1 has a low priority. In this case, the base station sends an uplink grant UL Grant2 to UE2 at t5 and sends UL Grant3 to UE3 at the same time.

[0070] In the above embodiment, UE3 receives the uplink grant in advance, which reduces the data transmission delay compared to the conventional process of continuing to wait for SR. The delay of UE3 receiving the uplink grant is reduced by (t9-t5). UE1 continues to wait and sends SR1 at t6.

[0074] The selection module 62 is configured to select a target associated terminal from the candidate associated terminals, for example, by performing the following steps: Figure 1 Step S120 is shown.
