Abstract

Claims (40)

1. A wireless power receiver device, comprising:

a power pickup circuit configured to receive a wireless power generated based on magnetic coupling from a wireless power transmitter device in a power transfer phase; and

a communication/control circuit configured to receive, from the wireless power transmitter device, information for a first buffer size,

wherein the information for the first buffer size informs a size of a first buffer for the wireless power transmitter device to receive a data transfer stream,

wherein the first buffer size is defined as a multiplication of a buffer size constant k and 2 n , and

wherein the n is a value related with the information for the first buffer size.

2. The wireless power receiver device of claim 1 , wherein the information for the first buffer size is received by being included in a capability packet of the wireless power transmitter device.

3. The wireless power receiver device of claim 1 , wherein the information for the first buffer size is received in a negotiation phase.

4. The wireless power receiver device of claim 1 , wherein the communication/control circuit is further configured to transmit, to the wireless power transmitter device, information for a second buffer size,

wherein the information for the second buffer size informs a size of a second buffer for the wireless power receiver device to receive a second data transfer stream.

5. The wireless power receiver device of claim 4 , wherein the information for the second buffer size is transmitted with being included in a configuration packet of the wireless power receiver device.

6. The wireless power receiver device of claim 4 , wherein the second buffer size is defined as a multiplication of a second buffer size constant k′ and 2 m , and,

wherein the m is a value related with the information for the second buffer size.

7. A wireless power transmitter device, comprising:

a power conversion circuit configured to transmit a wireless power generated based on magnetic coupling to a wireless power receiver device in a power transfer phase; and

a communication/control circuit configured to transmit, to the wireless power receiver device, information for a first buffer size,

wherein the information for the first buffer size informs a size of a first buffer for the wireless power transmitter device to receive a data transfer stream,

wherein the first buffer size is defined as a multiplication of a buffer size constant k and 2 n , and

wherein the n is a value related with the information for the first buffer size.

8. The wireless power transmitter device of claim 7 , wherein the information for the first buffer size is transmitted by being included in a capability packet of the wireless power transmitter device.

9. The wireless power transmitter device of claim 7 , wherein the information for the first buffer size is transmitted in a negotiation phase.

10. The wireless power transmitter device of claim 7 , wherein the communication/control circuit is further configured to receive, from the wireless power receiver device, information for a second buffer size,

wherein the information for the second buffer size informs a size of a second buffer for the wireless power receiver device to receive a second data transfer stream.

11. The wireless power transmitter device of claim 10 , wherein the information for the second buffer size is received with being included in a configuration packet of the wireless power receiver device.

12. The wireless power transmitter device of claim 10 , wherein the second buffer size is defined as a multiplication of a second buffer size constant k′ and 2 m , and

wherein the m is a value related with the information for the second buffer size.

13. A method performed by a wireless power receiver device, the method comprising:

receiving a wireless power generated based on magnetic coupling from a wireless power transmitter device in a power transfer phase; and

receiving, from the wireless power transmitter device, information for a first buffer size,

wherein the information for the first buffer size informs a size of a first buffer for the wireless power transmitter device to receive a data transfer stream,

wherein the first buffer size is defined as a multiplication of a buffer size constant k and 2 n , and

wherein the n is a value related with the information for the first buffer size.

14. The method of claim 13 , wherein the information for the first buffer size is received by being included in a capability packet of the wireless power transmitter device.

15. The method of claim 13 , wherein the information for the first buffer size is received in a negotiation phase.

16. The method of claim 13 , further comprising:

transmitting, to the wireless power transmitter device, information for a second buffer size,

wherein the information for the second buffer size informs a size of a second buffer for the wireless power receiver device to receive a second data transfer stream.

17. The method of claim 16 , wherein the information for the second buffer size is transmitted with being included in a configuration packet of the wireless power receiver device.

18. The method of claim 16 , wherein the second buffer size is defined as a multiplication of a second buffer size constant k′ and 2 m , and

wherein the m is a value related with the information for the second buffer size.
