摘要:
The specification and drawings present a new method, system, apparatus and software product for coordinating gating of an uplink (UL) control channel, e.g., a dedicated physical control channel (DPCCH), with UL reporting in regard to a downlink channel using, e.g., high speed uplink packet access (HSDPA) channel quality indicator (CQI) reporting.

The specification and drawings present a new method, system, apparatus and software product for defining a preamble length of a preamble (e.g., a power control preamble) for a discontinuous control channel transmission using, e.g., a dedicated physical control channel (DPCCH) for transmitting the preamble. The preamble length can be optimized using a predetermined criterion depending on a transmission gap length (which can be variable) in the discontinuous control signal (e.g., transmitted on the DPCCH) or in a discontinuous data signal, e.g., transmitted on an enhanced dedicated channel (E-DCH), and/or on a length of a transmission timing interval (TTI) of the discontinuous data. Furthermore, a power in the preamble can be changed in time using a further predetermined criterion.

The specification and drawings present a new method, system, apparatus and software product for dynamic gating of an uplink (UL) control channel, e.g., dedicated physical control channel (DPCCH) for increasing capacity of communications, e.g., wireless communications, wherein said gating is defined, using a predetermined criterion, by instructions provided by a network and by a transmission gap in a discontinuous data signal, e.g., transmitted on an enhanced dedicated channel (E-DCH).
摘要:
A method and corresponding equipment by which a service access point (SAP) of a radio access network is able to trigger a user equipment (UE) terminal to send scheduling information to the SAP for use by the SAP in scheduling/allocating resources for packet uplink from the UE to the SAP. The method uses an AG (absolute grant) or RG (relative grant) rate control/scheduling message as the trigger. The scheduling information is then sent by the UE via a MAC-e (medium access control-extended) PDU (protocol data unit).
摘要:
A faster power control method especially of use in case of a UE device communicating with a SAP (e.g. a Node B) of a UTRAN via E-DCH, where instead of the SAP (e.g. a Node B) receiving from the serving RNC a new SIR target to use because of changing channel conditions in what is called outer loop power control, the SAP instead receives a BLER target or a target value for some other indicator of channel quality (such as a new-data indicator value of EUPA) to use as a guide for determining, by itself, an appropriate SIR target.
摘要:
Parameters are defined for use on an interface (lub/lur) between network elements to enable configuration setup of an enhanced radio uplink (UL E-DCH). The basic Information Elements (IEs) are defined to support UL E-DCH functionality in the network on lub/lur. Particular parameters are shown for communication over the lub/lur interface between the RNCs and the Node Bs in order to be able to setup and re-configure the UL E-DCH channel. Flexibility is provided so as not to be restricted to any particular message or information element, but to be applicable to any selected message or messages in a given protocol.

摘要:
A method includes, in response to selection of a transport block to be transmitted through a wireless channel at a current data rate, performing at least the following: selecting a size for a data unit that can be scheduled for transmission; identifying one of a number of potential transport blocks, the identified potential transport block having a corresponding transport block size large enough to hold at least the selected size of the data unit and the transport block size of the currently selected transport block; determining whether the identified potential transport block is available for transmission; and transmitting a request for an increase in the current data rate in response to the identified potential transport block being available for transmission.
摘要:
A radio network element, including means for receiving data packets from a user equipment in a soft handover connection, means for determining whether the received data blocks have been received successfully or unsuccessfully, means for running a retransmission process for an un-successfully received data packet, and means for receiving control information instructing the size of memory to be reserved for retransmission processes of the connection.
摘要:
An approach is provided for cell re-selection. A notification message is generated to indicate initiation of a coverage area re-selection procedure to operate in a new coverage area from a current coverage area. The re-selection procedure is performed if an acknowledgement message is received in response to the notification message.
