Abstract

The present invention provides a method for transmitting data and a transceiver. In one embodiment, the method includes: (1) generating data blocks of a data package in a first transceiver to transmit to a second transceiver, the first transceiver including a micro-controller coupled to a digital signal processor, (2) generating identification data in the first transceiver for the data blocks, wherein the identification data is an index of a list of the data blocks to be transmitted and each of the data blocks is transmitted with the index and (3) identifying the data blocks to be transmitted to the second transceiver based on the identification data, wherein the microcontroller employs the index to manage transmission of the data blocks.

Claims

generating data blocks of multiple data packages in a first transceiver to transmit to a second transceiver, said first transceiver including a micro-controller coupled to a digital signal processor;

generating identification data in said first transceiver for said data blocks, wherein said identification data includes multiple lists of said data blocks to be transmitted and each of said data blocks is transmitted with at least one of said lists, wherein each of said lists corresponds to one of said multiple data packages and each said lists includes an index that indexes said lists; and

identifying said data blocks to be transmitted from said first transceiver to said second transceiver based on said identification data, wherein said micro controller employs said list to manage transmission of said data blocks and said identification data includes multiple lists, wherein each of said lists corresponds to one of said multiple data packages and each said lists includes an index that indexes said lists.

2. The method according to claim 1 further comprising transmitting said data blocks with said identification data in data frames to said second transceiver and identifying a transmission status of said data blocks transmitted to said second transceiver based on receiving said identification data in return from said second transceiver.

3. The method according to claim 1 wherein said generating said data blocks and said identification data is performed by said micro-controller, said method further comprising sending said data blocks and said identification data from said micro-controller to said digital signal processor in advance of transmission of said data blocks and storing said data blocks and said identification data in said digital signal processor until time for said transmitting.

4. The method according to claim 3 further comprising providing an interleaved communication between said micro-controller and said digital signal processor.

5. The method according to claim 3 further comprising:

transmitting acknowledgment signals with said identification data from said second transceiver to a receiving buffer of said first transceiver; and

providing said acknowledgment signals with said identification data to said micro-controller via said digital signal processor to indicate said transmission status of said data blocks.

6. The method according to claim 2 wherein said transmitting is via a multi-slot network, said method further comprising receiving a message to trigger said transmitting wherein said message is an Uplink State Flag from a base station that indicates which slot of said multi-slot network to use for said transmitting of said data blocks.

7. A transceiver capable of transmitting data blocks, comprising:

a micro-controller configured to generate data blocks of at least one data package to transmit to a second transceiver and generate identification data for said data blocks, wherein said identification data is a list of said data blocks to be transmitted and each of said data blocks is transmitted with said list, said microcontroller configured to employ said list to manage transmission of said data blocks;
