Methods, devices and computer program products providing for improved random access in a local area network environment

摘要

The present invention proposes methods in relation to providing for random access in a local area network environment, and encompasses, from an eNB perspective, defining (S1) a set of N dedicated preambles among a total number X of preambles, allocating (S4) a dedicated preamble to a terminal responsive to a connection request received from said terminal, and identifying (S9) said terminal when requesting random access, based on the allocated dedicated preamble contained in a random access request received. From a UE perspective, it encompasses requesting (S3) a connection to be established with a network transceiver device, receiving (S5) information on a dedicated preamble being allocated, and issuing (S8) a random access request to said network transceiver device which includes the allocated dedicated preamble. It also addresses correspondingly configured devices and computer program products.

1. A method, implemented by a network transceiver device, comprising:
defining a set of N dedicated preambles among a total number X of preambles, where N and X are each integers greater than one; allocating a dedicated preamble to a terminal responsive to a connection request received from said terminal; receiving a random access request message from the terminal as a first message in a random access channel (RACH) procedure, and identifying said terminal when requesting random access, based on the allocated dedicated preamble contained in the received random access request received; and granting random access to said terminal upon being identified based on the dedicated preamble and transmitting a random access response message as a second message in the RACH procedure to complete the RACH procedure without requiring further messaging between the terminal and the network transceiver device as part of the RACH procedure.
