Method and apparatus for configuring uplink hybrid automatic repeat request (HARQ) retransmission timer for narrowband communications

Abstract:

There is a need to support HARQ retransmission for narrow-band communications. The present disclosure provides a solution by supporting a HARQ retransmission timer for narrow-band communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The method for wireless communication at a user equipment may include receiving, by a user equipment (UE), a hybrid automatic repeat request (HARQ) retransmission timer, the HARQ retransmission timer indicates a time interval, identifying, by the (UE), data for uplink transmission, and starting, by the UE and after expiration of the HARQ retransmission timer, a random access procedure to obtain an uplink grant for the data.
