Description

Technical Field

[0001] The present invention relates to the field of wireless communication, and in particular to a method for scheduling a virtual antenna system, a data transmission method, and an apparatus. Background Art

[0002] In existing LTE (Long Term Evolution) and 5G NR (New Radio) systems, MIMO (multiple input multiple output) is a key technology for improving system capacity. To meet the demand for higher system capacity in 6G, virtual antenna technology opens up new ideas for continuously improving the MIMO spatial multiplexing ability by transforming the transmission channel matrix. In a virtual antenna system, the base station introduces an overlapping factor K, such that each transmitting antenna transmits a transmission signal asynchronously with an equal interval delay of 1 / K; the receiving end introduces an oversampling factor S, and oversamples the received signal at a rate higher than the Nyquist rate to obtain S-1 virtual receiving antennas. At this time, the dimension of the transmission channel matrix changes due to the oversampling process; through the above processing, multiple virtual receiving antennas are formed at the terminal in the virtual antenna system, so the number of data streams that can be decoded will be no less than the number of its physical antennas, thereby obtaining additional spatial multiplexing gain and virtual diversity reception gain.

[0003] Currently, in LTE and 5G NR systems, there is no delay and oversampling processing in the MIMO system. Therefore, during the user scheduling process, scheduling can be performed according to existing scheduling algorithms without considering the different overlapping multiplexing capabilities of the terminals and the oversampling capabilities of the base stations. However, when applying it to a virtual MIMO system, it may cause terminals with different overlapping multiplexing capabilities to be scheduled simultaneously. At this time, the base station will perform oversampling with a relatively high oversampling factor, resulting in a significant increase in power consumption. Summary of the Invention

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0076] Please refer to Figure 1-2 , an embodiment of the present invention provides a method for virtual antenna system scheduling, which is applied to a network-side device and includes:

[0077] Step 11: Receive the overlapping multiplexing capabilities sent by multiple terminals;

[0078] Step 12: Group the multiple terminals according to the overlapping multiplexing capabilities or the overlapping factors corresponding to the overlapping multiplexing capabilities;

[0083] Select the group as the current scheduling group;

[0084] Select at least some of the terminals in the current scheduling group as the current scheduling terminals;

[0085] Send the scheduling information to the current scheduling terminals.

[0086] In an embodiment of the present invention, according to the order of the priorities of the groups, from high to low or from low to high, select the group as the current group to be scheduled; the high or low of the priorities includes but is not limited to being determined according to the terminal with the highest or lowest priority in the group, or being determined according to the comprehensive priority of each group.

[0087] In an embodiment of the present invention, optionally, the maximum overlapping factor corresponding to each group is the least common multiple of the overlapping factors corresponding to the overlapping multiplexing capabilities of all the terminals in the group;

[0088] Or, the least common multiples of the overlapping factors corresponding to all the terminals in each group are different.

[0089] In an embodiment of the present invention, optionally, the maximum overlapping factors corresponding to each group are different.

[0090] In an embodiment of the present invention, optionally, after sending the scheduling information to the current scheduling terminals, it further includes:

[0091] Oversample the data sent by at least part of the currently scheduled terminals by using the oversampling factor corresponding to the current scheduling group, where the oversampling factor of the current scheduling group is determined according to the overlapping factor corresponding to the terminals within the current scheduling group.

[0092] In an embodiment of the present invention, optionally, the oversampling factor of the current scheduling group is the least common multiple of all the overlapping factors corresponding to the terminals within the current scheduling group.

[0093] In an embodiment of the present invention, the method for determining the oversampling factor includes, but is not limited to, the least common multiple of all the overlapping factors corresponding to the terminals within the current scheduling group; the grouping is performed to ensure that the oversampling factor of each group is minimized.

[0094] In an embodiment of the present invention, optionally, after oversampling the data sent by at least part of the currently scheduled terminals by using the maximum oversampling factor corresponding to the current scheduling group, the following steps are further included:

[0095] Demodulate the oversampled data according to the overlapping multiplexing capabilities of at least part of the terminals.

[0096] In an embodiment of the present invention, optionally, the step of grouping multiple terminals according to the overlapping multiplexing capabilities or the overlapping factors corresponding to the overlapping multiplexing capabilities includes:

[0097] Allocate a first terminal to a group with a smaller oversampling factor among the first groups; wherein the overlapping multiplexing capabilities or overlapping factors of the first terminal meet the allocation requirements of multiple first groups in the group.

[0098] In an embodiment of the present invention, optionally, the step of selecting the group as the current scheduling group includes:

[0099] Select the group as the currently scheduled group according to the order of the priorities of the groups, where the priorities of the groups are determined according to the first priority and / or the second priority, the first priority is determined according to the priorities of the terminals in the group, and the second priority is determined according to the service requirement priorities corresponding to the groups.

[0100] In an embodiment of the present invention, the first priority is determined according to the priorities of the terminals in the group. For example, the terminal with the highest or lowest priority in the current group, or the comprehensive priority of the terminals in the group. The second priority is determined according to the service requirement priorities corresponding to the groups.

[0101] In an embodiment of the present invention, optionally, the overlapping multiplexing capabilities are selected by the terminal from a preset set of overlapping multiplexing capabilities according to the capabilities of the terminal itself.

[0102] Please refer to Figure 2 In the embodiments of the present invention, the overlapping multiplexing capabilities sent by the receiving terminal are received, and multiple terminals are grouped according to the overlapping multiplexing capabilities or the overlapping factors corresponding to the overlapping multiplexing capabilities. There are four overlapping factors K1, K2, K3, and K4. K1 and K2 are assigned to group G1, and the over-sampling factor of this group is 4; K3 and K4 are assigned to group G2, and the over-sampling factor of this group is 6. For example, if group G1 has more terminals with higher priorities, then during the first scheduling, the base station selects group G1 for scheduling; the terminals within the current scheduling group send data to the base station according to their own overlapping multiplexing capabilities; the base station over-samples all received data with the current over-sampling factor and demodulates the data according to the different overlapping transmission capabilities of the scheduled terminals. For example: for a terminal with an overlapping factor of 2, sampling data is selected for demodulation at a sampling point interval of 4 / 2 = 2; for a terminal with an overlapping factor of 4, sampling data is selected for demodulation at a sampling point interval of 4 / 4 = 1; after all data transmissions of this group are completed, the base station switches the scheduling group and repeats the above process.

[0103] In the embodiments of the present invention, the terminals are grouped, the over-sampling factor of each group is determined, the priorities of different groups are determined, the base station schedules the group with the highest priority and the corresponding terminals, and the base station over-samples and demodulates all the data of the scheduled users with the over-sampling factor, which meets the relatively large throughput of the system and can effectively avoid the base station always being in high-fold over-sampling, reducing the power consumption of the base station.
