The WTRU then transmits the CQI via a random access channel (RACH).
The present invention provides a method involving a configurable random access channel structure.
A method and apparatus for supporting a random access using a random access channel (RACH) are disclosed.
Employment of the present invention allows the terminal to select, on the basis of the channel quality of self, the corresponding random access channel resource for random access channel transmission.
The method further includes selecting a random access channel based at least in part on the received load indications, and transmitting on the selected random access channel.
The UE performs a handover procedure with the target cell by transmitting a random access channel (RACH) preamble to the target base station.
Disclosed is a radio transmission device and a radio transmission method which reduces the RACH conflict ratio and improve the RACH detection characteristic.
A transceiver of the communications device attempts at least one first Random Access Channel (RACH) procedure with a first cell that is currently designated as a serving cell.
A wireless communication system includes a random access channel over which wireless devices can anonymously send requests for resources.
Also disclosed are a random access channel transmission method that is applicable at a network side, a corresponding terminal device, and a corresponding base station.
Embodiments of the present invention extend the benefits of mobile transmit diversity to the initialization phase of communication with a base station over a random access channel.
One embodiment of the method includes generating a random access channel burst that includes a cyclic prefix and a selected number of repetitions of a preamble.
In each time slot in which the random access channel is multiplexed, only data signals, which need not be retransmitted, are frequency-multiplexed.
An object identifier for detecting at least whether there is a user identifier uniquely assigned by the base station is included in the random access channel or the control channel
Systems and methods of pre-allocating identifiers to wireless devices for use in requesting resources over a random access channel are described.
The method and device can guarantee that channel quality detection of whole system may be implemented when a random access channel is allocated in the uplink pilot time slot.
The HBS can have a reduced transmission power during an uplink control channel or a random access channel of the uplink subframe of a mobile device transmission to the low power node.
Therefore, each terminal is mapped onto a reverse carrier by way of a mapping algorithm when a large number of M2M applications or smart terminals use the random access channel.
The wireless devices having the pre-allocated codes can transmit a particular code over the random access channel as a request for resources that uniquely identifies the requestor.
A random access channel to be transmitted for a wireless link connection is multiplexed in each of some of the time slots having predetermined time intervals therebetween.
In described examples, a wireless device (101) includes a preamble detector configured to identify preambles transmitted via a random access channel of a wireless network (100).
