Abstract
The present invention generally relates to digital communications, and more particularly, to a method and a device for sharing wireless transmission of first data and wireless reception of second data and an apparatus implementing the method.
Claims8
A method of synchronization between transmission of first data by a wireless transceiver and reception of second data by a wireless receiver, wherein the method comprising:
- receiving said second data by said wireless receiver, said second data being received in a form of a data burst;
- determining characteristics of said receiving of said second data, said characteristics comprising a burst on-time of said data burst, a burst periodicity of said data burst, and information representative of a time of reception of different layers of said second data when said second data is encoded according to a scalable video encoding, said scalable video encoding comprising a base layer and at least one enhancement layer for rendering said second data with different quality;
- determining a time period for transmission, via said wireless transceiver, of at least part of said first data based upon said characteristics, said time period for transmission comprising a burst off-time of said data burst and said time period for transmission comprising said on-time of said data burst corresponding to a reception of said second data from said at least one scalable video enhancement layer when said second data is encoded according to said scalable video encoding;
- transmitting, during said time period, and via said wireless transceiver, a request for reservation of a time slot for transmission of at least part of said first data;
- receiving, via said wireless transceiver, information representative of a time slot reservation;
- and
- transmitting, via said wireless transceiver, said at least part of said first data during said reserved time slot, when said reserved time slot is in said determined time period for transmission.

A device, wherein the device comprises:
- a first determinator for determination of characteristics of reception of first data by a wireless receiver, said first data being received in a form of a data burst, said characteristics of reception of first data comprising a burst on-time of said data burst, a burst periodicity of said data burst, and information representative of a time of reception of different layers of said second data when said second data is encoded according to a scalable video encoding, said scalable video encoding comprising a base layer and at least one enhancement layer for rendering said first data with different quality;
- a second determinator for determination of a time period for transmission by a wireless transceiver of at least part of said second data, said second determinator taking into account said characteristics of reception of first data, said time period for transmission comprising a burst off-time of said data burst and said time period for transmission comprising said on-time of said data burst corresponding to a reception of said second data from said at least one scalable video enhancement layer when said second data is encoded according to a said scalable video encoding;
- said wireless transceiver for transmitting, during said time period, a request for reservation of a time slot for transmission of at least part of said first data;
- said wireless receiver for receiving information representative of a time slot reservation;
- and
- said wireless transceiver for transmitting said at least part of said first data during said reserved time slot, when said reserved time slot is in said time period for transmission determined by said second determinator.
