The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a user equipment for setting a HARQ-ACK feedback mode.
[ background of the invention ]
With the rapid development of modern wireless communication technology, wireless communication networks provide more and more services, from traditional voice services to multimedia services, even cloud computing, etc., which requires that next-generation communication systems can provide higher data rates. However, compared with wired transmission, the environment experienced by signal transmission in wireless communication is much more complex, and the transmission is affected by complex terrain between transceivers, high-speed movement between transceivers, interference of surrounding radio and the like, and shows strong random time-varying fading characteristics. As the bandwidth of a communication system increases, the transmission rate increases, and the influence of fading becomes more serious. This not only affects the reliability of the communication, but also reduces the energy efficiency and spectral efficiency of the network. Therefore, the wireless communication system needs to have an error control technique to ensure the reliability of data transmission and guarantee the requirement of the user on the service quality.
A Hybrid Automatic Repeat reQuest (HARQ) technology is a transmission technology widely used in mobile communication systems. However, in the current network, a Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK) feedback mode is set to be one of a Multiplexing (Multiplexing) mode or a Bundling (Bundling) mode, and cannot be set and adjusted. The multiplexing mode occupies a large amount of resources, and the poor radio environment in the binding mode results in a large amount of retransmissions, thereby resulting in low feedback efficiency of the ue.

[ detailed description ] A
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be understood that the term "and/or" as used herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., A and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Fig. 1 is a schematic diagram of a multiplexing mode in an embodiment of the present invention, and as shown in fig. 1, the multiplexing mode is to spatially bind different CODE WORDs (CW) of the same subframe of the same ue, that is, perform a logical and operation on Acknowledgement (ACK) feedback of two CODE WORDs. For example, each of the 4 subframes has 1 bit response feedback result. In this mode, the acknowledgement/Non-acknowledgement (ACK/NACK) status of each subframe is reflected, avoiding extra retransmissions. However, when there are many user equipments, a multiplexing feedback mode is adopted, which occupies a lot of resources.
For example, in fig. 1, with two different codewords CW1 and CW2 in a subframe, the two codewords CW1 and CW2 can be spatially bundled using a multiplexing mode. One subframe is a bonding combination comprising CW1 and CW2, and each subframe correspondingly generates one 1-bit response feedback, i.e. four 1-bit response feedbacks are generated. Therefore, the multiplexing mode is to perform logic and operation on the response feedback of the two code words, and the response/non-response state of each sub-frame obtains the corresponding feedback result.
Fig. 2 is a working principle diagram of a binding mode in the embodiment of the present invention, and as shown in fig. 2, the binding mode logically and-operates ACK/NACK of the same codeword in different downlink subframes of the same user equipment. In this mode, if a certain subframe fails to be transmitted, all subframes are retransmitted, resulting in a high retransmission rate.
For example, in fig. 2, in the bundling mode, a subframe for single-codeword acknowledgement/non-acknowledgement bundling feedback and a subframe for double-codeword acknowledgement/non-acknowledgement bundling feedback are set, the subframe for single-codeword acknowledgement/non-acknowledgement bundling feedback includes CW1, and the subframe for double-codeword acknowledgement/non-acknowledgement bundling feedback includes two different codewords, CW1 and CW 2. Thus only one 1-bit acknowledgement feedback is generated when logically anding the same CW1 acknowledgement/non-acknowledgement bundling feedback in multiple subframes for single codeword acknowledgement/non-acknowledgement bundling feedback, while two 1-bit acknowledgement feedbacks are generated when logically anding the same CW1 acknowledgement/non-acknowledgement bundling feedback in multiple subframes and the same CW2 acknowledgement/non-acknowledgement bundling feedback in multiple subframes for double codeword acknowledgement/non-acknowledgement bundling feedback. Whereas in the case of different codewords in the same 4 subframes, the multiplexing mode results in four 1-bit acknowledgement feedbacks. Therefore, the bundling mode, i.e. performing logical and operation on the same codeword CW of different subframes, can reduce the resource occupation problem, but if a subframe fails to be transmitted, a large number of retransmissions will result.
Fig. 3 is a flowchart of a method for setting a HARQ-ACK feedback mode according to an embodiment of the present invention, and as shown in fig. 3, the method includes:
step S101, judging that the HARQ-ACK feedback mode of the user equipment is a binding mode or a multiplexing mode, and executing step 102 if the HARQ-ACK feedback mode is judged to be the multiplexing mode; if the HARQ-ACK feedback mode is determined to be the bundling mode, execute step 104.

And step S104, judging whether the acquired second PDCCH load is smaller than a first threshold value.
Step S105, if the second PDCCH load is judged to be smaller than the first threshold value, the HARQ-ACK feedback mode is set to be the multiplexing mode.
In the technical scheme of the setting method of the HARQ-ACK feedback mode provided by the embodiment of the invention, the HARQ-ACK feedback mode of the user equipment is judged to be a binding mode or a multiplexing mode; if the HARQ-ACK feedback mode is judged to be the multiplexing mode, judging whether the acquired first PDCCH load is larger than or equal to a first threshold value; if the first PDCCH load is judged to be greater than or equal to the first threshold value, the HARQ-ACK feedback mode is set to be the binding mode; if the HARQ-ACK feedback mode is judged to be the binding mode, judging whether the acquired second PDCCH load is smaller than a first threshold value; if the second PDCCH load is judged to be smaller than the first threshold value, the HARQ-ACK feedback mode is set to be the multiplexing mode, mode conversion is carried out by combining the PDCCH load, the problem of resource occupation or the problem of a large number of retransmission caused by single mode is avoided by the setting mode, and the feedback efficiency of the user equipment is improved.
Fig. 4 is a flowchart of a setting method of a HARQ-ACK feedback mode according to another embodiment of the present invention, and as shown in fig. 4, the method includes:
step S201, judging that the HARQ-ACK feedback mode of the user equipment is a binding mode or a multiplexing mode, and if the HARQ-ACK feedback mode is judged to be the multiplexing mode, executing step S202; if the HARQ-ACK feedback mode is determined to be the bundling mode, step S204 is executed.
In this embodiment, each step may be performed by a User Equipment (UE for short).
In this embodiment, the HARQ-ACK feedback mode of the ue may be set as one of a multiplexing mode and a bundling mode, and in the embodiment of the present invention, it needs to determine that the HARQ-ACK feedback mode of the ue is in the multiplexing mode or the bundling mode, and perform mode switching by combining with the PDCCH load, which avoids the problem of resource occupation or the problem of a large number of retransmissions due to a single mode, and improves the feedback efficiency of the ue.
Step S202, determining whether the acquired first PDCCH load is greater than or equal to a first threshold, if so, performing step S203, and if not, performing step S202.
In this embodiment, before step 202, the method further includes: according to the set time interval, the first PDCCH load is periodically acquired, for example, the time interval can be set to 1 minute granularity, namely PDCCH load information of a cell is acquired every other minute, so that the accuracy of acquiring the PDCCH load in real time is ensured, a corresponding feedback mode is set in a better self-adaptive manner, and the feedback efficiency of user equipment is improved.
In this embodiment, a first threshold may be preset, and typically, the first threshold may be 50%. And the user equipment compares the acquired PDCCH load with the first threshold value so as to determine whether the HARQ-ACK feedback mode of the user equipment needs to be changed.
Step S203, the HARQ-ACK feedback mode is set to the binding mode.
In the embodiment of the present invention, optionally, step S201 may be further performed after step 203.
In this embodiment, when the PDCCH of the cell is heavily loaded, the HARQ-ACK feedback mode of the user equipment is set to the bundling mode, so that the problem that the user equipment occupies a large amount of resources due to too many user equipments is avoided.
Step S204, determining whether the obtained Signal to Interference plus Noise Ratio (SINR) is less than a second threshold, if so, performing step S205, and if not, performing step S204.
In this embodiment, before step 204, the method further includes: periodically acquiring a Measurement Report (MR); and extracting the SINR of the user equipment from the acquired measurement report. In this embodiment, the SINR of the cell edge where the ue is located may be obtained.
In this embodiment, according to the set time interval, the SINR is periodically obtained, for example, the second threshold is set to 3, and the time interval is set to 1 minute granularity, that is, the SINR information of one piece of user equipment is obtained every one minute, so that the accuracy of obtaining the SINR in real time is ensured, and thus, a corresponding feedback mode is better adaptively set, and the feedback efficiency of the user equipment is improved.
Step S205, determining whether the acquired second PDCCH load is smaller than a first threshold, if so, performing step S206, and if not, performing step S205.
In this embodiment, before step 205, the method further includes: according to the set time interval, the second PDCCH load is periodically acquired, for example, the time interval can be set to 1 minute granularity, namely PDCCH load information of a cell is acquired every other minute, so that the accuracy of acquiring the PDCCH load in real time is ensured, a corresponding feedback mode is set in a better self-adaptive manner, and the feedback efficiency of the user equipment is improved.
Step S206, the HARQ-ACK feedback mode is set to the multiplexing mode.
In the embodiment of the present invention, optionally, step S201 may be further performed after step 206.
In this embodiment, when the wireless environment of a single ue at the edge of a cell is poor, that is, the SINR is poor, the retransmission rate may become high, and the HARQ-ACK feedback mode of the ue is set as the multiplexing mode, so that the problem of the retransmission rate becoming high due to the SINR becoming poor is avoided.
In the technical scheme of the setting method of the HARQ-ACK feedback mode provided by the embodiment of the invention, the HARQ-ACK feedback mode of the user equipment is judged to be a binding mode or a multiplexing mode; if the HARQ-ACK feedback mode is judged to be the multiplexing mode, judging whether the acquired first PDCCH load is larger than or equal to a first threshold value; if the first PDCCH load is judged to be greater than or equal to the first threshold value, the HARQ-ACK feedback mode is set to be the binding mode; if the HARQ-ACK feedback mode is judged to be the binding mode, judging whether the acquired second PDCCH load is smaller than a first threshold value; and if the second PDCCH load is judged to be smaller than the first threshold value, setting the HARQ-ACK feedback mode as the multiplexing mode, and carrying out mode conversion by combining the PDCCH load. In this embodiment, by determining whether the periodically obtained SINR is smaller than the second threshold and performing the step of determining whether the obtained second PDCCH load is smaller than the first threshold, the HARQ-ACK feedback mode of the user equipment may be set back to the multiplexing mode, and mode switching is performed by combining the PDCCH load and the SINR, which avoids the problem of resource occupation or the problem of a large number of retransmissions caused by a single mode, and improves the feedback efficiency of the user equipment. In this embodiment, mode switching is performed by combining PDCCH load and SINR of the ue, and this adaptive setting mode takes both edge users and capacity load into consideration, so that the advantages of both can be absorbed, and the working efficiency of the ue is improved.
