Methods and devices for facilitating data retransmissions in wireless communication systems

摘要

Wireless communications devices are adapted to perform retransmissions of data blocks. A wireless communications device can be adapted to transmit a plurality of data blocks to a receiving device. When the plurality of data blocks are transmitted, the wireless communications device can initiate a block timer associated with a round trip time for communications between the wireless communications device and the receiving device. When, prior to expiration of the block timer, a transmission is received with an indication that at least one data block was not successfully received, the wireless communications device can retransmit the unsuccessful data block. On retransmission, the block timer is restarted. If another transmission is received prior to expiration of the restarted block timer, the wireless communications device can ignore any indication of unsuccessful receipt associated with the retransmitted data block. Other aspects, embodiments, and features are also claimed and described.

1. A wireless communications device, comprising:
a communications interface; a storage medium; and a processing circuit coupled to the communications interface and the storage medium, the processing circuit adapted to:
transmit a plurality of data blocks via the communications interface;initiate a block timer associated with a round trip time for each data block of the plurality of data blocks in response to transmission of the plurality of data blocks;receive a first transmission via the communications interface, the received first transmission including a first indication that at least one data block of the plurality of data blocks has not been successfully received, wherein the first transmission is received prior to expiration of the block timer;retransmit the at least one data block via the communications interface in response to the first indication that the at least one data block of the plurality of data blocks has not been successfully received;restart the block timer in response to retransmission of the at least one data block;receive a second transmission via the communications interface, the second received transmission including a second indication that the at least one retransmitted data block has not been successfully received, wherein the second transmission is received prior to expiration of the restarted block timer; andignore the second indication that the at least one retransmitted data block has not been successfully received in response to the second indication being received prior to expiration of the restarted block timer.
