Method and apparatus for controlling discontinuous transmissions

摘要

Techniques for controlling discontinuous transmissions in a wireless communication system are described. A method and apparatus for transmitting data on an uplink includes tracking past performance of at least one of an uplink channel condition and uplink system resources. A prediction of a likelihood of a completed or successful data transmission is performed. A long preamble is transmitted with an uplink control channel when the prediction indicates a likelihood of completion of the data transmission. When past performance indicates an unlikelihood of completing the transmission of the data, then the discontinuous mode is maintained without data transmission.

主权项

1. A method of transmitting data on an uplink, comprising:
tracking past performance including recent history at a user equipment (UE) of at least one of an uplink channel condition and uplink system resources determined at the UE, wherein, the uplink system resources comprises a past performance of grants of wireless network resources over the uplink during a defined time period; predicting a likelihood of a completed data transmission based on the past performance comprises predicting when data to be transmitted is present; weighting the prediction based on a priority value of the data; and transmitting from the UE a long preamble with an uplink control channel when the prediction exceeds a threshold.
