## Abstract

Provided are a slot aggregation and device, a slot aggregation transmission method and device, a storage medium, and an electronic device. The slot aggregation method includes: setting, in a slot aggregation process, one or more slot intervals in N slots, wherein a duration of each slot interval is one or more slots; or setting, in a slot aggregation process, N slots as continuous slots, wherein the number of resources allocated in an nth slot of the N slots is less than the number of resources allocated in the (n−1)th slot; or setting, in a slot aggregation process, N slots as X slot groups, wherein a transmission format of each slot group is pre-configured by a base station, N is an integer greater than 1 and less than or equal to n, and X is less than N.

## Claims

### Claim 1

A slot aggregation transmission method, comprising:
setting aggregated slots as T slot sub-groups;
configuring beams for the T slot sub-groups; and
transmitting the T slot sub-groups by the configured beams, wherein T is an integer greater than 2.

### Claim 2 (depends on 1)

The method according to claim 1, wherein configuring the beams for the T slot sub-groups comprises:
setting a first beam or a first beam group for the T slot sub-groups, wherein the first beam group comprises a plurality of beams, and the plurality of beams are used for transmitting x1 slots in the slot sub-groups, and x1 is a positive integer.

### Claim 3 (depends on 2)

The method according to claim 2, wherein transmitting the T slot sub-groups by the configured beams comprises:
transmitting the T slot sub-groups by the configured first beam or first beam group.

### Claim 4 (depends on 3)

The method according to claim 3, wherein transmitting the T slot sub-groups by the configured beams comprises:
after transmitting the (t−1)th slot sub-group by the configured first beam or first beam group, receiving feedback information, fed back by the terminal, of transmitting the t-th slot sub-group by a second beam or a second beam group;
configuring, according to the feedback information, the second beam or the second beam group for the t-th slot sub-group; and
transmitting the t-th slot sub-group by the second beam or the second beam group, wherein the second beam group comprises a plurality of beams, and the plurality of beams are used for transmitting x2 slots in the slot sub-group, where t is an integer greater than or equal to 1, and less than T, and x2 is a positive integer.

### Claim 5 (depends on 4)

The method according to claim 4, wherein transmitting the T slot sub-groups by the configured beams comprises:
in a case of not receiving the feedback information from the terminal, transmitting the (t+1)th slot sub-group by the second beam or the second beam group, or transmitting the (t+1)th slot sub-group by the first beam or the first beam group; and
in a case of receiving the feedback information, fed back by the terminal, of transmitting the (t+1)th slot sub-group by a third beam or a third beam group, transmitting the (t+1)th slot sub-group by the third beam or the third beam group, wherein the third beam group comprises a plurality of beams, and the plurality of beams are used for transmitting x3 slots in the slot sub-group, and x3 is a positive integer.

### Claim 6 (depends on 1)

The method according to claim 1, wherein transmitting the T slot sub-groups by the configured beams comprises:
receiving feedback information, fed back by the terminal, of changing or replacing the beams allocated for the slot sub-groups;
changing or replacing, according to the feedback information, the beams allocated for the slot sub-groups; and
transmitting the slot sub-groups by the changed or replaced beams.

### Claim 7 (depends on 1)

The method according to claim 1, wherein configuring the beams for the T slot sub-groups comprises:
configuring a group of beams for the T slot sub-groups, wherein for the T slot sub-groups, polling is performed in the group of beams.

### Claim 8 (depends on 7)

The method according to claim 7, wherein transmitting the T slot sub-groups by the configured beams comprises:
receiving feedback information, fed back by the terminal, of changing or replacing the beams allocated for the slot sub-groups;
changing or replacing, according to the feedback information, the beams allocated for the slot sub-groups; and
transmitting the slot sub-groups according to the changed or replaced beams, wherein the changed or replaced beams are beams in the group of beams or beams other than the group of beams;
or,
transmitting the T slot sub-groups by the configured beams comprises:
receiving feedback information, fed back by the terminal, of removing one or more beams from the group of beams;
removing the one or more beams from the group of beams according to the feedback information, wherein for un-transmitted slot sub-groups in the aggregated slots, polling is performed in remaining beams of the group of beams; and
transmitting, according to the group of beams from which one or more beams have been removed, the un-transmitted slot sub-groups in the aggregated slots;
or,
transmitting the T slot sub-groups by the configured beams comprises:
receiving feedback information, fed back by the terminal, of adding one or more beams to the group of beams;
adding the one or more beams to the group of beams according to the feedback information, wherein for un-transmitted slot sub-groups in the aggregated slots, polling is performed in the group of beams into which one or more beams have been added; and
transmitting, according to the group of beams into which one or more beams have been added, the un-transmitted slot sub-groups in the aggregated slots.

### Claim 9 (depends on 1)

A slot aggregation transmission device, comprising a memory storing instructions and a processor in communication with the memory, wherein the processor is configured to execute the instructions to perform the method according to claim 1.
