METHOD AND APPARATUS FOR INDICATING TRANSMISSION TIME INTERVAL

摘要

Embodiments of the present invention disclose a method and an apparatus for indicating a transmission time interval. The implementation solutions of the method includes: receiving an access preamble from a user equipment UE, where the access preamble carries a signature; determining whether a cell where the UE is located is configured with an extended acquisition indicator EAI, and sending, on an acquisition indicator channel AICH of an access timeslot corresponding to an access timeslot where the access preamble is received, an acquisition indicator AI corresponding to the signature of the access preamble. Therefore, the problem that the judging condition of EAI configured is always YES is solved; the UE access delay may be reduced; the number of preambles sent by the UE may be reduced; and interference on the uplink may be reduced.

1. A method comprising:
receiving an access preamble from a user equipment (UE), wherein the access preamble carries a signature; and determining whether a cell where the UE is located is configured with an extended acquisition indicator (EAI), and sending, on an acquisition indicator channel (AICH) of an access timeslot corresponding to an access timeslot where the access preamble is received, an acquisition indicator (AI) corresponding to the signature of the access preamble; wherein when a value of the AI is a first value, default resources associated with the signature of the access preamble which are used by the UE and a transmission time interval (TTI) type requested by the UE are allocated and indicated, or default resources associated with the AI corresponding to the signature of the access preamble which are used by the UE and a TTI type requested by the UE are allocated and indicated.
