Collision detection for random access procedure

An apparatus, comprising:

• means for selecting random access parameters for a random access procedure;
• means for scheduling a data transmission from a communication device on an uplink data channel using said random access parameters for said random access procedure;
• means, in response to the scheduling, for receiving from a network element a configuration signal including an acquisition message;
• means, in response to the acquisition message, for starting the data transmission on the uplink data channel;
• means for interrupting said data transmission after a predetermined time interval in response to said apparatus not receiving from said network element during said predetermined time interval a permission signal indicating permission to continue said random access procedure, said permission signal comprising an identification of the communication device from said network element during said predetermined time interval, and said permission signal comprising an indication of a data rate to transmit the data transmission, wherein said permission signal is configured to be received over an absolute grant channel, an enhanced dedicated channel, a hybrid automatic repeat request acknowledgement indicator channel or on a high-speed shared control channel;
• and
• means for rescheduling said data transmission following a randomized time interval in response to interrupting said data transmission.

A non-transitory computer readable medium tangibly encoded with a computer program executable by a processor to perform actions comprising:

• selecting random access parameters for a random access procedure;
• scheduling a data transmission on an uplink data channel from a communication device to a network element using said random access parameters for said random access procedure;
• in response to the scheduling, receiving from said network element a configuration signal including an acquisition message;
• in response to the acquisition message, starting the data transmission on the uplink data channel;
• interrupting said data transmission after a predetermined time interval in response to said communication device not receiving from said network element during said predetermined time interval a permission signal indicating permission to continue said random access procedure, said permission signal comprising an identification of the communication device from said network element during said predetermined time interval, and said permission signal comprising an indication of a data rate to transmit the data transmission, wherein said permission signal is configured to be received over an absolute grant channel, an enhanced dedicated channel, a hybrid automatic repeat request acknowledgement indicator channel or on a high-speed shared control channel;
• and
• in response to interrupting said data transmission, rescheduling said data transmission following a randomized time interval.

A method, comprising:

• selecting random access parameters for a random access procedure;
• scheduling a data transmission on an uplink data channel from a communication device to a network element using said random access parameters for said random access procedure;
• in response to the scheduling, receiving from said network element a configuration signal including an acquisition message;
• in response to the acquisition message, starting the data transmission on the uplink data channel;
• interrupting said data transmission after a predetermined time interval in response to said communication device not receiving from said network element during said predetermined time interval a permission signal indicating permission to continue said random access procedure, said permission signal comprising an identification of the communication device from said network element during said predetermined time interval, and said permission signal comprising an indication of a data rate to transmit the data transmission, wherein said permission signal is configured to be received over an absolute grant channel, an enhanced dedicated channel, a hybrid automatic repeat request acknowledgement indicator channel or on a high-speed shared control channel;
• and
• in response to interrupting said data transmission, rescheduling said data transmission following a randomized time interval.
