Abstract: A random access procedure for use by a UE wireless communication terminal in communicating with a base station (or Node-B or eNB) of a radio access network, and in particular a E-UTRA network. A random access preamble is sent by the UE via RACH separate and prior to a random access message burst, which is sent on SCH but not until the UE receives one or more messages indicating an acknowledgment of the preamble and providing an allocation on SCH for use in transmitting the message burst, and also providing a preamble identifier, which the radio access network can then use to request retransmission of the message burst if necessary.

Abstract: A method for communicating between nodes in a communication system. Communicating in a first node in a radio access network and a second node in a core network using messages associated with a first set of operations connecting the first node to the core network. Communicating in the first node with other nodes of the radio access network using messages associated with a second set of operations connecting the radio access network nodes. Communicating in the first node with a third node using messages associated with a third set of operations, the third set of operations providing at least part of the operations provided by the first and second set of operations. The scalability of the core network nodes is enhanced when the number of the radio access network nodes connecting to the core network nodes increases.

Abstract: A transmitter for a packet radio network, including means for transmitting a signal including data packets to a receiver, means for receiving acknowledgement messages from the receiver, each acknowledgement message indicating whether or not a data packet was received successfully, and means for adjusting transmit power of the signal in the transmitter on the basis of one or more acknowledgement messages.

Abstract: An apparatus includes a radio frequency receiver and a timing adjustment unit that contains at least two channel impulse response estimators. The at least two channel impulse response estimators include an on-time estimator and at least one of an early estimator and a late estimator. The apparatus also includes a calculation unit that is configurable to obtain a channel estimate for each measured channel impulse response and to average obtained channel estimates over a plurality of received signal events to determine a timing adjustment in accordance with residual signal power.

Abstract: A sequence restriction method is shown applicable for an uplink (UL) scheduling request in order to increase resistance against frequency error. A cyclic shift restriction is applied to the orthogonal cover codes used in a scheduling request structure. For an uplink scheduling request, the transmitter selects sequences which tolerate high Dopplers and/or frequency errors. Performance of scheduling requests is improved for UEs having high Doppler/frequency error (reduces false alarm rate). In addition, the improvement is obtained without changing the scheduling request structure. As a result, the multiplexing capacity of scheduling requests is not reduced in environments where there are no high speed UEs.

Abstract: In a non-limiting aspect thereof, the exemplary embodiments of this invention provide a method that includes starting a timer in a base station after sending a handover information message, and stopping the timer upon a condition, including either receiving an expected handover related message, or expiration of a maximum allowed time value of the timer.

Abstract: A method providing embedded status information in handover control related messages. The method is operable in an E-UTRAN environment and supports ARQ scheme considerations. A device, computer program and apparatus are also disclosed.
