Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1a is a flowchart of a method for confirming uplink data reception in a first embodiment of the present invention, where this embodiment is applicable to a case where a terminal confirms whether uplink data sent by the terminal is received by a base station, and the method may be executed by an apparatus for confirming uplink data reception, where the apparatus may be implemented by hardware and/or software, and may be generally integrated in an electronic device, for example, a terminal device. As shown in fig. 1, the method is applied to a terminal, and includes:
and step 110, transmitting the uplink data to the base station by using the target uplink data transmission time slot in the target frame.
In this embodiment, the terminal accesses the base station, the base station provides service for the terminal, the target uplink data transmission timeslot in the target frame is a timeslot 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 timeslot to transmit uplink data to the base station.
Optionally, before using the target uplink data transmission timeslot in the target frame and transmitting uplink data to the base station, the method may further include: and sending a 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 a timeslot resource that can be sufficiently used for sending the uplink data, the terminal may determine the number and the period of the required timeslot resources according to the traffic volume of the terminal itself, generate a resource request signaling according to the number and the period of the required timeslot resources, and send the resource request signaling to the base station, and then acquire a target uplink data sending timeslot in a target frame allocated by the base station to the terminal itself according to the resource request signaling, so as to send the uplink data to the base station through the target uplink data sending timeslot in the following process.
Optionally, the obtaining of the target uplink data transmission timeslot in the target frame allocated by the base station for the terminal according to 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 deviation value of at least one target uplink data transmission time slot in a target frame allocated to the terminal by the base station; 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 position of a 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 cycle 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 to the terminal by the base station, and taking the field value of the corresponding time slot cycle 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, that is, 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 carry out data transmission, resource conflict does not exist between the terminals.
And 120, extracting data confirmation indication information in a confirmation indication sending time slot of a subsequent associated frame matched with the target frame.
The data confirmation indication information is generated by the base station according to the receiving condition of the uplink data transmitted in each uplink data transmission time slot in the target frame.
In this embodiment, in order to enable the terminal to still confirm whether the transmitted uplink data is received by the base station without performing uplink data reception confirmation in a one-to-one manner with the base station, the terminal may receive data confirmation indication information transmitted by the base station in a specified time slot of a subsequent associated frame matching the target frame, where the data confirmation indication information may indicate that the base station receives uplink data transmitted in each uplink data transmission time slot in the target frame, so that the terminal may confirm the reception of each transmitted uplink data according to the data confirmation indication information.
Optionally, the target frame is a superframe, the subsequent association frame is a last superframe directly adjacent to the target frame or separated by at least one other superframe, and the confirmation indication sending time slot is a sending time slot of a beacon frame in the subsequent association frame.
In this embodiment, as shown in fig. 1b, the base station may use a superframe structure to define the access time of each terminal to the channel, for example, terminal 1 uses slot 0 and terminal 2 uses slot 1 and slot 5 in the superframe, and the superframe is defined by transmitting a beacon frame, and each superframe starts with the beacon frame, that is, the acknowledgement indication transmission slot may be the first slot in the subsequent association frame matching the target frame.
In order to realize that the base station can perform batch acknowledgement on the receiving conditions of a plurality of uplink data sent by each terminal at a time and 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 acknowledgement indication information corresponding to the target frame is extracted from the beacon frame, so that the terminal can determine whether the 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 acknowledgement indication information. When the duration of the data reception confirmation situation of the terminal meets the requirement, the terminal may also acquire the beacon frame in the first time slot of the last superframe separated from the target frame by at least one superframe and extract the data confirmation indication information corresponding to the target frame from the beacon frame.
And step 130, determining whether the uplink data is received by the base station according to the data confirmation indication information.
Optionally, determining whether the 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 indicating information; if the target indicated value is a first numerical value, determining that the uplink data sent in the target uplink data sending time slot is received by the base station; and if the target indicated value is the second value, determining 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 reception statuses of the uplink data transmitted in the uplink data transmission timeslots in the target frame, and when the target indication value is set to a first value in advance, it indicates that the uplink data transmitted in the corresponding target uplink data transmission timeslot is received by the base station, and when the target indication value is set to a second value, it indicates that the uplink data transmitted in the corresponding target uplink data transmission timeslot is not received by the base station, and then the base station can determine the reception statuses of the uplink data transmitted in the target uplink data transmission timeslot after obtaining the data acknowledgement indication information.
The first numerical value may be set to 1, the second numerical value may be set to 0, the first numerical value may be set to 0, the second numerical value may be set to 1, or the first numerical value and the second numerical value may be set to different numerical values or characters.
For example, 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. the target frame includes N slots. Taking terminal 2 as an example, target uplink data transmission time slots occupied by terminal 2 in a target frame are time slot 1 and time slot 5, and target indication values corresponding to time slot 1 and time slot 5, which are obtained from data acknowledgement indication information corresponding to the target frame, are both 1, so that it can be determined that uplink data transmitted by terminal 2 in time slot 1 and time slot 5 are both received by the base station. Taking the terminal 7 as an example, if the target uplink data transmission timeslot occupied by the terminal 7 in the target frame is timeslot 2, and the target indication value corresponding to timeslot 2 in the data acknowledgement indication information is 0, it may be determined that the base station has not received the uplink data transmitted by the terminal 7 in timeslot 2, and the terminal 7 needs to retransmit the uplink data.
According to the technical scheme of the embodiment of the invention, the terminal sends the uplink data to the base station by using the target uplink data sending time slot in the 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 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 is determined, the problems that in the prior art, the resource utilization rate is low and the implementation complexity of the base station is high when the base station and the terminal perform uplink data receiving confirmation in a one-to-one mode are solved, the base station performs batch confirmation on the uplink data receiving condition, the resource utilization rate is improved, and the implementation complexity of the base station is reduced.
Example two
Fig. 2 is a flowchart of a method for confirming uplink data reception in a second embodiment of the present invention, where this embodiment is applicable to a case where a base station performs batch confirmation on uplink data reception, and the method may be executed by an uplink data reception confirmation apparatus, and the apparatus may be implemented by hardware and/or software, and may be generally integrated in an electronic device, for example, a base station device. As shown in fig. 1, the method is applied to a base station, and includes:
In this embodiment, the target uplink data transmission timeslot in the target frame is a timeslot resource that is allocated by the base station to each terminal according to the requirement of each terminal, and each terminal can use the target uplink data transmission timeslot allocated by the base station to transmit uplink data to the base station.
Optionally, before receiving uplink data sent by each terminal in a target uplink data sending timeslot in a target frame, the method may further include: and receiving resource request signaling sent by each terminal, and allocating target uplink data sending time slots 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 the period of time slot resources that need to be requested, which are calculated by each terminal according to the traffic of each terminal, are extracted from each resource request signaling, and then target uplink data sending time slots in a target frame are allocated to each terminal respectively according to the number and the period of time slot resources requested by each terminal.
Optionally, allocating a target uplink data transmission timeslot in a target frame for each terminal according to each resource request signaling may include: aiming at a current resource request signaling, allocating at least one target uplink data transmission time slot in a target frame for a 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 sending time slot and feeding back the resource allocation signaling to the current terminal.
In this embodiment, when allocating a time slot resource to each terminal, the base station may select a corresponding number of target uplink data transmission time slots from the target frame according to the number of the time slot resources requested by the current terminal and a preset resource allocation algorithm, for example, a round-robin scheduling algorithm, a maximum carrier-to-interference ratio scheduling algorithm, or a proportional fairness algorithm, to allocate the target uplink data transmission time slots to the current terminal, and generate a resource allocation signaling corresponding to the current resource request signaling of the current terminal according to a position offset value of the selected target uplink data transmission time slots in the target frame, and feed the resource allocation signaling back to the current terminal, so that the current terminal may determine a specific position of the time slot resource occupied by itself in the target frame by analyzing the resource allocation signaling.
In this embodiment, in order to enable the terminal to still confirm whether or not the uplink data transmitted by the terminal is received by the base station when the base station does not perform uplink data reception confirmation in a one-to-one manner with respect to the terminal, 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 may 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 data acknowledgement indication information corresponding to the target frame according to a receiving condition of uplink data sent in each uplink data sending timeslot in the target frame, where the generating may include: sequentially acquiring uplink data transmission time slots in a target frame as target uplink data transmission time slots; if uplink data sent in a target uplink data sending time slot is received, setting a target indicated value corresponding to the target uplink data sending time slot as a first numerical 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 numerical value in the data confirmation indication information.
In this embodiment, the base station may sequentially receive data for each uplink data transmission timeslot in the target frame, set a target indication value corresponding to a certain uplink data transmission timeslot as a first value if the base station receives uplink data in the certain uplink data transmission timeslot, set a target indication value corresponding to the uplink data transmission timeslot as a second value if no valid uplink data is received in the certain uplink data transmission timeslot, and then sequentially splice the target indication values corresponding to the uplink data transmission timeslots according to positions of the uplink data transmission timeslots in the target frame to generate data acknowledgement indication 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 slot resources, the data acknowledgement indication information corresponding to the target frame occupies N bits, and each bit corresponds to a target indication value of an uplink data transmission slot in the target frame. As shown in fig. 1c, when the base station receives the uplink data in the time slot 0, the target indication value 1 is stored in the bit corresponding to the time slot 0, and when the base station does not receive the uplink data transmitted by the terminal in the time slot 2, the target indication value 0 is stored in the bit corresponding to the time slot 2, and so on, the data acknowledgement indication information corresponding to the target frame is generated.
And step 230, sending data confirmation indication information to each terminal by using a confirmation indication sending time slot of the subsequent associated frame matched with the target frame, so that each terminal determines whether the uplink data is received by the base station according to the data confirmation indication information.
Optionally, the target frame is a superframe, the subsequent association frame is a last superframe directly adjacent to the target frame or separated by at least one other superframe, and the confirmation indication sending time slot is a sending time slot of a beacon frame in the subsequent association frame.
In this embodiment, as shown in fig. 1b, the base station may use a superframe structure to define the access time of each terminal to the channel, for example, terminal 1 uses slot 0 and terminal 2 uses slot 1 and slot 5 in the superframe, and the superframe is defined by transmitting a beacon frame, and each superframe starts with the beacon frame, that is, the acknowledgement indication transmission slot may be the first slot in the subsequent association frame matching the target frame.
In order to realize that the base station can perform batch confirmation on the receiving conditions of a plurality of uplink data sent by each terminal at a time and improve the utilization rate of resources, a beacon frame carrying data confirmation indication information can be sent 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 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. When the duration of the data reception confirmation by the terminal satisfies the requirement, the terminal may transmit a beacon frame to each terminal in the first time slot of the last superframe separated from the target frame by at least one superframe so that each terminal may extract the data confirmation indication information corresponding to the target frame from the beacon frame.
In this embodiment, by adding data acknowledgement indication information corresponding to the reception situation of the uplink data transmitted in each uplink data transmission slot in the target frame to the beacon frame, the base station does not need to perform uplink data reception acknowledgement one-to-one with each terminal, thereby improving the radio resource utilization rate, and the base station maintains the data reception situation of all uplink data transmission slots in the target frame, and does not need to maintain the information of each terminal corresponding to the target frame, thereby simplifying information maintenance and reducing implementation complexity.
According to the technical scheme of the embodiment of the invention, a base station receives uplink data sent by each terminal in a target uplink data sending time slot in a target frame; generating data confirmation indication information corresponding to the target frame according to the receiving condition of the uplink data transmitted in each uplink data transmission time slot in the target frame; the method and the device use the confirmation indication sending time slot of the subsequent associated frame matched with the target frame to send the data confirmation indication information to each terminal so that each terminal can determine whether the uplink data is received by the base station according to the data confirmation indication information, solve the problems that the base station and the terminal carry out uplink data receiving confirmation one to one in the prior art, the resource utilization rate is low, and the realization complexity of the base station is high, realize that the base station carries out periodic batch confirmation on the receiving condition of the uplink data, improve the resource utilization rate and reduce the realization complexity of the base station.

first, the base station periodically transmits a beacon frame to each terminal, so that each terminal achieves time synchronization with the base station according to the received beacon frame.
In this embodiment, as shown in fig. 3b, the base station sends a beacon frame to each terminal in a broadcast manner in the first time slot of each super-frame, and after each terminal searches for the beacon frame sent by the base station, the terminal performs time synchronization with the base station according to the UTC time included in the beacon frame. For example, the frame structure of the beacon frame may be as shown in table 1:

As shown in table 1, the beacon frame further includes data acknowledgment indication information corresponding to a superframe preceding the current superframe, or the beacon frame includes data acknowledgment indication information corresponding to a superframe preceding at least one other superframe at an interval of the current superframe.
The terminal then sends a resource request signaling to the base station.
In this embodiment, as shown in fig. 3b, after time synchronization between the terminal and the base station, the terminal may determine the number and the period of the required time slot resources according to the traffic volume of the terminal, and generate a resource request signaling according to the number and the period of the required time slot resources, and send the resource request signaling to the base station, so that the base station sends the time slot for the target uplink data in the target frame allocated to the base station according to the resource request signaling. Wherein the target frame may be the current superframe.
For example, the signaling format of the resource request signaling may be as shown in table 2:
TABLE 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 cycle of 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 to allocate to the terminal according to a preset resource allocation algorithm, and generates a resource allocation signaling corresponding to the resource request signaling of the terminal according to a position offset value of the selected target uplink data transmission timeslot in the target frame, and feeds the resource allocation signaling back to the terminal, as shown in fig. 3 b.
For example, the signaling format of the resource allocation signaling may be as shown in table 3:
TABLE 3
| Parameter(s) | Size (byte) | Description of the invention |
| MsgId | 0.5 | Message type, |
| Num | 0.5 | Number of allocated |

| >offset | 2 | The position offset value of the time slot can be larger than N; |

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 slot offset values and a slot cycle included in the resource allocation signaling, and then determines a slot resource that can be used in a target frame according to a position offset value of each target uplink data transmission slot.
Each time slot resource 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 carry out data transmission, resource conflict does not exist between the terminals.
Then, the terminal transmits uplink data to the base station using the target uplink data transmission slot in the target frame.
Next, the base station generates data acknowledgement instruction information corresponding to the target frame based on the reception of the uplink data transmitted in each uplink data transmission slot in the target frame.
In this embodiment, the base station sequentially receives data of each uplink data transmission timeslot in the target frame, if the base station receives uplink data in a certain uplink data transmission timeslot, the base station sets a target indication value corresponding to the uplink data transmission timeslot to 1, if no valid uplink data is received in a certain uplink data transmission timeslot, the base station sets a target indication value corresponding to the uplink data transmission timeslot to 0, and then sequentially concatenates the target indication values corresponding to the uplink data transmission timeslots according to positions of the uplink data transmission timeslots in the target frame to generate data acknowledgement indication information corresponding to the target frame, as shown in fig. 1 c.
And then, the base station transmits a beacon frame carrying data confirmation indication information to each terminal by using a confirmation indication transmission time slot of a subsequent association frame matched with the target frame.
In this embodiment, the base station may send a beacon frame carrying data acknowledgement indication information to each terminal in a first time slot of a next superframe directly adjacent to the target frame, or send a beacon frame to each terminal in a first time slot of a next superframe separated from the target frame by at least one superframe.
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 data acknowledgement indication information corresponding to the target frame from the received beacon frame, and obtain, from the data acknowledgement indication information, a target indication value corresponding to each target uplink data transmission timeslot in the target frame; if the target indicated value is 1, determining that the uplink data transmitted in the target uplink data transmission time slot is received by the base station; and if the target indicated value is 0, determining that the uplink data transmitted in the target uplink data transmission time slot is not received by the base station.
