摘要:
A load control method is described herein that enables a base station to broadcast three downlink signals including a busy indicator, a maximum resource indicator and a minimum resource indicator to a mobile terminal. In response to receiving the downlink signals, the mobile terminal limits the utilization of a resource (e.g., bit rate, transmission power, power offset) it uses to transmit data to the base station. The mobile terminal may also send an uplink signal including a resource request to the base station. The base station can use the resource request to change the downlink signals if needed. It is with the proper use of these uplink/downlink signals that the behavior of the base station can be automatically optimized to the load situation.

Methods for improving uplink communications in a Wideband Code Division Multiple Access (WCDMA) communication system, wherein mobile terminals can transmit at various transmission power levels. In a mobile terminal, the method includes the steps of receiving a configuration message having at least one of a power offset parameter and a maximum number of retransmission attempts parameter; when the mobile terminal performs a non-scheduled transmission, it transmits according to the parameters contained in the configuration message. In a network node, the method includes the steps of transmitting to at least one mobile terminal the configuration message having at least one of a power offset parameter and a maximum number of retransmission attempts parameter; and, adjusting a power setting for the transmission of acknowledgement or negative-acknowledgement messages from the wireless network to one or more of mobile terminals.

A user equipment unit (30) and a base station node (28) which is configured for operation with a synchronous HARQ protocol and with capability of sending data on an E-DCH channel either (1) in a nominal mode in single transmission time intervals of a predetermined length, or (2) in an extended mode in a pseudo transmission time interval. The pseudo transmission time interval comprises a first transmission time interval in which the data is transmitted and a second transmission time interval in which the data is re-transmitted. The second transmission time interval is consecutive to the first transmission time interval, and the first transmission time interval and the second transmission time interval are each of the (same) predetermined length.
摘要:
A radio resource management technique in a cellular telecommunication system is disclosed. The telecommunication system comprises at least one radio network controlling component and one or more base station components operable to implement an uplink scheduling scheme in relation to one or more user terminals. A method embodiment comprises the steps of receiving, by one of the base station components from the at least one radio network controlling component, at least one interference control parameter, of generating one or more scheduling grants taking into account the at least one interference control parameter, and of issuing the one or more scheduling grants to one or more user terminals.
摘要:
The invention relates to a method and an arrangement for obtaining efficient radio resource allocation in a mobile communication network comprising a communication network entity (15) and at least one user equipment (18) transmitting data to said mobile communication network entity (15) over a radio interface. A first data transmission from said at least one user equipment (18) is received, whereby said first transmission is decoded and a message (ACK/NACK) based on a result of the decoding is sent on a downlink channel (13) comprising information of said first received data transmission. A second data transmission from said at least one user equipment (18) is received, whereby the power on said downlink channel (13) is adjusted depending on the result of said decoding and the content in said received second data transmission.
