Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1a is a flowchart of a method for acknowledging receipt of uplink data in a first embodiment of the present invention, where the present embodiment is applicable to a case where a terminal acknowledges whether uplink data sent by the terminal is received by a base station, and the method may be performed by an apparatus for acknowledging receipt of uplink data, where the apparatus may be implemented by hardware and/or software, and may be generally integrated in an electronic device, for example, in a terminal device. As shown in fig. 1a, the method is applied to a terminal, and includes:
step 110, uplink data is sent to the base station by using the target uplink data sending time slot in the target frame.
In this embodiment, the terminal accesses the base station, and is served by the base station, and the target uplink data transmission time slot in the target frame is a time slot resource allocated to the terminal by the base station according to the requirement of the terminal, and the terminal can use the target uplink data transmission time slot to transmit uplink data to the base station.
Optionally, before the uplink data is sent to the base station by using the target uplink data sending time slot in the target frame, the method may further include: and sending the resource request signaling to the base station, and acquiring a target uplink data sending time slot in a target frame allocated to the terminal by the base station aiming at the resource request signaling.
In this embodiment, before sending uplink data to the base station, in order to obtain timeslot resources that can be used for sending uplink data sufficiently, the terminal may determine the number and period of required timeslot resources according to its own traffic, generate a resource request signaling according to the number and period of required timeslot resources, send the resource request signaling to the base station, and then obtain a target uplink data sending timeslot in a target frame allocated by the base station for itself according to the resource request signaling, so as to send uplink data to the base station through the target uplink data sending timeslot subsequently.
Optionally, the obtaining the target uplink data transmission time slot in the target frame allocated by the base station for the terminal aiming at the resource request signaling may include: receiving a resource allocation signaling returned by the base station aiming at the resource request signaling; analyzing the resource allocation signaling, and acquiring a position offset value of at least one target uplink data transmission time slot in a target frame allocated by a base station for a terminal; and determining the position of each target uplink data transmission time slot in the target frame according to the position offset value of each target uplink data transmission time slot.
In this embodiment, after sending the resource request signaling to the base station, the resource allocation signaling returned by the base station for the resource request signaling may be received, where the resource allocation signaling is used to indicate a specific location of the timeslot resource allocated by the base station for the terminal. Analyzing the resource allocation signaling according to the signaling format of the resource allocation signaling, finding at least one pair of time slot offset fields and time slot period fields included in the resource allocation signaling, taking the field value of each time slot offset field as the position offset value of each target uplink data transmission time slot in a target frame allocated by the base station for the terminal, and taking the field value of the corresponding time slot period field as the use period of each target uplink data transmission time slot. Starting from the initial time slot in the target frame, according to the position offset value of each target uplink data transmission time slot, the specific position of each target uplink data transmission time slot in the target frame can be determined, namely the time slot resource which can be used in the target frame is determined.
Each time slot can only be used by one terminal, so that when each terminal uses the target uplink data transmission time slot allocated by the base station to perform data transmission, no resource conflict exists among the terminals.
Step 120, extracting data acknowledgement indication information in the acknowledgement indication transmission time slot of the subsequent associated frame matched with the target frame.
The data confirmation instruction information is generated by the base station according to the receiving condition of the uplink data sent in each uplink data sending time slot in the target frame.
In this embodiment, in order to enable the terminal to confirm whether the transmitted uplink data is received by the base station without performing uplink data reception confirmation with the base station in one-to-one manner, the terminal may receive data confirmation instruction information sent by the base station in a designated time slot of a subsequent associated frame matched with the target frame, where the data confirmation instruction information may instruct the base station to confirm the receiving condition of each uplink data transmitted in each uplink data transmission time slot in the target frame according to the receiving condition of each uplink data transmitted in the target frame, so that the terminal may confirm the receiving condition of each uplink data transmitted according to the data confirmation instruction information.
Optionally, the target frame is a superframe, the subsequent associated frame is a subsequent superframe directly adjacent to the target frame or separated by at least one other superframe, and the acknowledgement indication transmission time slot is a transmission time slot of a beacon frame in the subsequent associated frame.
In this embodiment, as shown in fig. 1b, the base station may use a superframe structure to define access time of each terminal to the channel, for example, the terminal 1 uses the time slot 0 in the superframe, the terminal 2 uses the time slot 1 and the time slot 5 in the superframe, and the superframe is defined by transmitting beacon frames, and each superframe starts with a beacon frame, that is, the acknowledgement indication transmission time slot may be the first time slot in the subsequent associated frame matched with the target frame.
In order to realize batch confirmation of the receiving condition of a plurality of uplink data sent by each terminal at one time, the base station can improve the utilization rate of resources, a beacon frame can be acquired in the first time slot of the next super frame directly adjacent to the target frame, and data confirmation indication information corresponding to the target frame is extracted from the beacon frame, so that the terminal can determine whether uplink data sent by the terminal in the target uplink data sending time slot in the target frame is received by the base station according to the data confirmation indication information. In the case that the duration of the terminal acknowledging the data reception condition satisfies the requirement, the beacon frame may be acquired in the first time slot of the succeeding superframe of at least one superframe spaced from the target frame, and the data acknowledgement indication information corresponding to the target frame may be extracted from the beacon frame.
Step 130, determining whether the uplink data is received by the base station according to the data confirmation indication information.
Optionally, determining whether uplink data is received by the base station according to the data acknowledgement indication information may include: acquiring a target indicated value corresponding to each target uplink data transmission time slot from the data confirmation indicated information; if the target indicated value is the first value, determining that uplink data transmitted in the target uplink data transmission time slot is received by the base station; if the target indication value is the second value, it is determined that the uplink data transmitted in the target uplink data transmission time slot is not received by the base station.
In this embodiment, the data acknowledgement indication information includes target indication values corresponding to the receiving conditions of the uplink data sent in each uplink data sending slot in the target frame, when the target indication value is preset to be a first value, it indicates that the uplink data sent in the corresponding target uplink data sending slot is received by the base station, and when the target indication value is set to be a second value, it indicates that the uplink data sent in the corresponding target uplink data sending slot is not received by the base station, and after obtaining the data acknowledgement indication information, the base station can determine the receiving condition of the uplink data sent in the target uplink data sending slot.
Wherein the first value may be set to 1, the second value may be set to 0, the first value may be set to 0, the second value may be set to 1, or the first value and the second value may be set to other different values or characters.
Illustratively, as shown in fig. 1c, assuming that the first value is 1 and the second value is 0, the length of the target frame is N, i.e., N slots are included in the target frame. Taking the terminal 2 as an example, the target uplink data transmission time slots occupied by the terminal 2 in the target frame are time slots 1 and 5, and the target indication values corresponding to the time slots 1 and 5 are both 1 from the data acknowledgement indication information corresponding to the target frame, so that it can be determined that the uplink data transmitted by the terminal 2 in the time slots 1 and 5 are received by the base station. Taking the terminal 7 as an example, when the target uplink data transmission time slot occupied by the terminal 7 in the target frame is time slot 2 and the target indication value corresponding to time slot 2 in the data acknowledgement indication information is 0, it can be determined that the base station does not receive the uplink data transmitted by the terminal 7 on time slot 2, and the terminal 7 needs to retransmit the uplink data.
According to the technical scheme, the terminal sends uplink data to the base station by using a target uplink data sending time slot in a target frame; extracting data confirmation indication information in a confirmation indication sending time slot of a subsequent associated frame matched with the target frame, wherein the data confirmation indication information is generated by the base station according to the receiving condition of the uplink data sent in each uplink data sending time slot in the target frame; according to the data confirmation indication information, whether the uplink data is received by the base station or not is determined, the problems that in the prior art, the base station and the terminal perform one-to-one uplink data receiving confirmation, the resource utilization rate is low, and the realization complexity of the base station is high are solved, the base station performs batch confirmation on the uplink data receiving condition, the resource utilization rate is improved, and the realization complexity of the base station is reduced.
Example two
Fig. 2 is a flowchart of a method for confirming reception of uplink data in the second embodiment of the present invention, where the present embodiment is applicable to a case where a base station performs batch confirmation on a reception situation of uplink data, and the method may be performed by an apparatus for confirming reception of uplink data, where the apparatus may be implemented by hardware and/or software, and may be generally integrated in an electronic device, for example, a base station side device. As shown in fig. 2, the method is applied to a base station, and includes:
step 210, receiving uplink data sent by each terminal in a target uplink data sending time slot in a target frame.
In this embodiment, the target uplink data transmission time slot in the target frame is a time slot resource allocated to each terminal by the base station according to the requirement of each terminal, and each terminal may use the target uplink data transmission time slot allocated by the base station to transmit uplink data to the base station.
Optionally, before receiving the uplink data sent by each terminal in the target uplink data sending timeslot in the target frame, the method may further include: and receiving the resource request signaling sent by each terminal, and distributing a target uplink data sending time slot in a target frame for each terminal aiming at each resource request signaling.
In this embodiment, before receiving uplink data sent by a terminal, a resource request signaling sent by each terminal is received, the number and period of time slot resources to be requested, which are calculated by each terminal according to its own traffic, are extracted from each resource request signaling, and then, according to the number and period of time slot resources requested by each terminal, target uplink data sending time slots in a target frame are respectively allocated to each terminal.
Optionally, allocating, for each terminal, a target uplink data transmission time slot in a target frame for each resource request signaling may include: aiming at the current resource request signaling, at least one target uplink data transmission time slot in a target frame is allocated to the current terminal according to a preset resource allocation algorithm; and generating a resource allocation signaling corresponding to the current resource request signaling according to the position offset value of each target uplink data transmission time slot, and feeding back the resource allocation signaling to the current terminal.
In this embodiment, when the base station allocates the timeslot resources for each terminal, according to the number of timeslot resources requested by the current terminal, according to a preset resource allocation algorithm, for example, a polling scheduling algorithm, a maximum carrier-to-interference ratio scheduling algorithm, or a proportional fairness algorithm, a corresponding number of target uplink data transmission timeslots are selected from a target frame to be allocated to the current terminal, and according to the position offset value of the selected target uplink data transmission timeslots in the target frame, a resource allocation signaling corresponding to the current resource request signaling of the current terminal is generated, and the resource allocation signaling is fed back to the current terminal, so that the current terminal can determine the specific position of the timeslot resources occupied by itself in the target frame by analyzing the resource allocation signaling.
Step 220, generating data confirmation instruction information corresponding to the target frame according to the receiving situation of the uplink data sent in each uplink data sending time slot in the target frame.
In this embodiment, in order that the terminal can still confirm whether or not uplink data transmitted by the terminal is received by the base station without performing uplink data reception confirmation with the terminal in one-to-one manner, the base station may generate data confirmation instruction information corresponding to the target frame according to the reception condition of the uplink data transmitted in each uplink data transmission slot in the target frame, so that each terminal can confirm the reception condition of the uplink data transmitted by itself in each target uplink data transmission slot in the target frame according to the data confirmation instruction information.
Optionally, generating the data acknowledgement indication information corresponding to the target frame according to the receiving situation of the uplink data sent in each uplink data sending time slot in the target frame may include: sequentially acquiring uplink data transmission time slots in a target frame as target uplink data transmission time slots; if uplink data transmitted in a target uplink data transmission time slot is received, setting a target indication value corresponding to the target uplink data transmission time slot as a first value in data confirmation indication information; and if the uplink data transmitted in the target uplink data transmission time slot is not received, setting a target indication value corresponding to the target uplink data transmission time slot as a second value in the data acknowledgement indication information.
In this embodiment, the base station may sequentially perform data reception on each uplink data transmission timeslot in the target frame, if the base station receives uplink data in a certain uplink data transmission timeslot, set a target instruction value corresponding to the uplink data transmission timeslot to a first value, if no valid uplink data is received in a certain uplink data transmission timeslot, set a target instruction value corresponding to the uplink data transmission timeslot to a second value, and then sequentially splice the target instruction values corresponding to the uplink data transmission timeslots according to the positions of each uplink data transmission timeslot in the target frame, so as to generate data acknowledgement instruction information corresponding to the target frame.
For example, as shown in fig. 1c, assuming that the first value is 1, the second value is 0, and the length of the target frame is N, that is, the target frame includes N time slot resources, the data acknowledgement indication information corresponding to the target frame occupies N bits, and each bit corresponds to the target indication value of one uplink data transmission time slot in the target frame. As shown in fig. 1c, when the base station receives uplink data in the time slot 0, the base station stores the target indication value 1 in the bit corresponding to the time slot 0, when the base station does not receive uplink data sent by the terminal in the time slot 2, the base station stores the target indication value 0 in the bit corresponding to the time slot 2, and so on, and generates data acknowledgement indication information corresponding to the target frame.
And 230, transmitting data confirmation indication information to each terminal by using the confirmation indication transmission time slot of the subsequent associated frame matched with the target frame, so that each terminal determines whether uplink data is received by the base station according to the data confirmation indication information.
Optionally, the target frame is a superframe, the subsequent associated frame is a subsequent superframe directly adjacent to the target frame or separated by at least one other superframe, and the acknowledgement indication transmission time slot is a transmission time slot of a beacon frame in the subsequent associated frame.
In this embodiment, as shown in fig. 1b, the base station may use a superframe structure to define access time of each terminal to the channel, for example, the terminal 1 uses the time slot 0 in the superframe, the terminal 2 uses the time slot 1 and the time slot 5 in the superframe, and the superframe is defined by transmitting beacon frames, and each superframe starts with a beacon frame, that is, the acknowledgement indication transmission time slot may be the first time slot in the subsequent associated frame matched with the target frame.
In order to realize batch confirmation of the receiving condition of a plurality of uplink data sent by each terminal at one time, the base station can improve the utilization rate of resources, and can send a beacon frame carrying data confirmation indication information to each terminal in the first time slot of the next super frame directly adjacent to the target frame, so that each terminal can extract the data confirmation indication information corresponding to the target frame from the beacon frame, and further determine whether the uplink data sent by the base station in the target uplink data sending time slot in the target frame is received by the base station according to the data confirmation indication information.

Example III
Fig. 3a is a flowchart of an implementation of an application scenario to which the embodiment of the present invention is applicable, and this embodiment may be combined with various alternatives in the above embodiment. Specifically, referring to fig. 3a, the method may comprise the steps of:
first, the base station periodically transmits a beacon frame to each terminal so that each terminal can achieve time synchronization with the base station according to the received beacon frame.
In this embodiment, as shown in fig. 3b, the base station will send a beacon frame to each terminal in a broadcast manner in the first time slot of each superframe, and after each terminal searches for the beacon frame sent by the base station, the base station will perform time synchronization with the base station according to the UTC time included in the beacon frame. Illustratively, the frame structure of the beacon frame may be as shown in table 1:
TABLE 1
Figure SMS_1
As shown in table 1, the beacon frame further includes data acknowledgement indication information corresponding to a superframe preceding the current superframe or data acknowledgement indication information corresponding to a preceding superframe of at least one other superframe of the current superframe.
Then, the terminal transmits a resource request signaling to the base station.
In this embodiment, as shown in fig. 3b, after time synchronization with the base station, the terminal may determine the number and period of the required time slot resources according to its own traffic, and generate a resource request signaling according to the number and period of the required time slot resources, and send the resource request signaling to the base station, so that the base station sends a time slot for the target uplink data in the target frame allocated for itself according to the resource request signaling. Wherein the target frame may be the current superframe.
Exemplary, the signaling format of the resource request signaling may be as shown in table 2:
TABLE 2
Figure SMS_2
Then, the base station feeds back a resource allocation signaling to the terminal so that the terminal determines a target uplink data transmission time slot in a target frame occupied by the terminal.
In this embodiment, after receiving the resource request signaling, the base station extracts the number and period of the timeslot resources requested by the terminal from the resource request signaling, selects a corresponding number of target uplink data transmission timeslots from the target frame according to a preset resource allocation algorithm, allocates the target uplink data transmission timeslots to the terminal, and generates a resource allocation signaling corresponding to the resource request signaling of the terminal according to the position offset value of the selected target uplink data transmission timeslots in the target frame, and feeds back the resource allocation signaling to the terminal, as shown in fig. 3 b.
Exemplary, the signaling format of the resource allocation signaling may be as shown in table 3:

>offset 2 The position offset value of the time slot may be greater than N;
>Period 1 period of time slot
……
>offset 2 The position offset value of the time slot may be greater than N;
>Period 1 period of time slot
In this embodiment, after receiving a resource allocation signaling returned by a base station for a resource request signaling, a terminal analyzes the resource allocation signaling according to a signaling format of the resource allocation signaling to obtain at least one pair of time slot offset values and a time slot period included in the resource allocation signaling, and then determines a time slot resource that can be used in a target frame according to a position offset value of each target uplink data transmission time slot.
Each time slot resource can only be used by one terminal, so that when each terminal uses a target uplink data transmission time slot allocated by a base station to perform data transmission, no resource conflict exists among the terminals.
Then, the terminal transmits uplink data to the base station using the target uplink data transmission slot in the target frame.
Then, the base station generates data confirmation instruction information corresponding to the target frame according to the reception situation of the uplink data transmitted in each uplink data transmission time slot in the target frame.
In this embodiment, the base station sequentially receives data from each uplink data transmission timeslot in the target frame, if the base station receives uplink data in a certain uplink data transmission timeslot, the target instruction value corresponding to the uplink data transmission timeslot is set to 1, if no valid uplink data is received in a certain uplink data transmission timeslot, the target instruction value corresponding to the uplink data transmission timeslot is set to 0, and then, according to the position of each uplink data transmission timeslot in the target frame, the target instruction values corresponding to each uplink data transmission timeslot are spliced together in sequence, so as to generate data confirmation instruction information corresponding to the target frame, as shown in fig. 1 c.
Then, the base station transmits a beacon frame carrying data acknowledgement indication information to each terminal using an acknowledgement indication transmission slot of a subsequent associated frame matching the target frame.
In this embodiment, the base station may transmit a beacon frame carrying the data acknowledgement indication information to each terminal in the first time slot of the subsequent superframe immediately adjacent to the target frame, or transmit a beacon frame to each terminal in the first time slot of the subsequent superframe of at least one superframe apart from the target frame.
And finally, the terminal receives the beacon frame and determines whether the uplink data is received by the base station according to the data confirmation indication information in the beacon frame.
In this embodiment, the terminal may extract, from the received beacon frame, data acknowledgement indication information corresponding to the target frame, and obtain, from the data acknowledgement indication information, a target indication value corresponding to each target uplink data transmission slot in the target frame; if the target indicated value is 1, determining that uplink data transmitted in the target uplink data transmission time slot is received by the base station; if the target indication value is 0, it is determined that the uplink data transmitted in the target uplink data transmission slot is not received by the base station.
