Method for detecting data transmission and data reception, and base station and user device
View Patent ↗A non-orthogonal method for detecting data transmission and data reception, and base station and user device, relating to communication technology; when the base station sends data, first multiplying a plurality of data by means of by a weighted value and/or implementing conjugate processing, then mapping the data onto physical resources, the amount thereof being no greater than the amount of data, each data in the plurality of data resources being mapped to at least one physical resource, and the amount of physical resources each data is mapped to not being completely the same; and then sending the data on the physical resources, thereby sending more data by means of less physical resources, improving the data transmission capacity of a communication system.
1. A method for transmitting data, the method comprising:
mapping multiples pieces of data onto physical resources by multiplying the data with weights, and/or conjugating the data, wherein the number of physical resources is no more than the number of pieces of data, each piece of data is mapped onto at least one of the physical resources, and the number of physical resources onto which each piece of data is mapped is not exactly the same as each other; and
transmitting the data over the physical resources.
2. The method according to claim 1 , wherein the number of pieces of data mapped onto each physical resource is no more than the number of physical resources.
3. The method according to claim 2 , wherein the data mapped onto the same physical resource are superimposed and then transmitted.
4. The method according to claim 3 , wherein the data are superimposed linearly.
5. The method according to claim 1 , wherein the pieces of data are divided into multiple layers, wherein the number of physical resources onto which each piece of data in the preceding layer is mapped is larger than the number of physical resources onto which each piece of data in the succeeding layer is mapped.
6. The method according to claim 5 , wherein the different data divided into the same layer are mapped onto the same number of physical resources.
7. The method according to claim 5 , wherein the data in different layers are multiplied with different weights, wherein the weight of the preceding layer is more than the weight of the succeeding layer, and the different data in the same layer are multiplied with the same weight.
8. The method according to claim 1 , wherein the pieces of data belong to at least two users.
9. A method for receiving and detecting data, the method comprising:
receiving, by a User Equipment, UE, data transmitted by a base station over multiple physical resources; and
detecting by the UE, the data mapped onto the multiple physical resources according to mapping mode, wherein the number of pieces of data mapped onto the physical resources is no less than the number of physical resources, each piece of data is mapped onto at least one of the physical resources, and the number of physical resources onto which each piece of data is mapped is not exactly the same as each other; and the pieces of data are divided into multiple layers, wherein the data in different layers are multiplied with different weights, the weight of the preceding layer is more than the weight of the succeeding layer, and the different data in the same layer are multiplied with the same weight; and/or data in each layer are conjugated.
10. A base station, comprising:
a transceiver, a processor, a memory, and a bus interface, wherein the processor and the memory are connected with the transceiver through the bus interface;
the processor is configured with one or more executable programs configured to perform a method comprising: mapping multiples pieces of data onto physical resources by multiplying the data with weights, and/or conjugating the data, wherein the number of physical resources is no more than the number of pieces of data, each piece of data is mapped onto at least one of the physical resources, and the number of physical resources onto which each piece of data is mapped is not exactly the same as each other;
the transceiver is configured to transmit the data over the physical resources;
the memory is configured to store the one or more executable programs for configuring the processor; and
the bus interface is configured to serve as an interface.
11. The base station according to claim 10 , wherein the number of pieces of data mapped onto each physical resource is no more than the number of physical resources.
12. The base station according to claim 11 , wherein the data mapped onto the same physical resource are superimposed and then transmitted.
13. The base station according to claim 12 , wherein the data are superimposed linearly.
14. The base station according to claim 10 , wherein the pieces of data are divided into multiple layers, wherein the number of physical resources onto which each piece of data in the preceding layer is mapped is larger than the number of physical resources onto which each piece of data in the succeeding layer is mapped.
15. The base station according to claim 14 , wherein the different data divided into the same layer are mapped onto the same number of physical resources.
16. The base station according to claim 10 , wherein the pieces of data belong to at least two users.
