    摘要: An uplink common physical channel (random access channel) frame structure with a separate preamble and data portion. The preamble is used by a base station to detect that a mobile station is attempting a random access request. The data portion of the channel includes user data, and pilot symbols that provide energy for channel estimation during reception of the data portion. A guard interval is preferably inserted between the preamble and data portion of the frame, which enables data detection to occur during an idle period. As such, the frame structures for both the common physical (random access) uplink channel and dedicated physical (traffic) uplink channel are compatible.

    摘要: The present invention relates to improvements for a fast setup of physical communication channels in a CDMA-based communication system. A Node B of a telecommunication network is permitted to manage and assign a certain share of the downlink transmission resources of a radio network controller without inquiry of said radio network controller. On reception of a resource request message from a user equipment, the node B derives and specifies a certain amount of said resources that can be allocated to the user equipment. In a preferred embodiment of the present invention said resources are only assigned temporarily until the ordinary RL setup procedure, which involves the RNC, has been successfully finished.

    摘要: In a synchronization scheme, for example for establishing a channel in a UMTS radio communication system, when a user device (or user equipment, UE) such as a mobile terminal is establishing a channel with a network, the user device transmits signals on the uplink DPCCH, and the power of these signals is ramped up from a calculated initial power level until the transmission is detected by the receiver, i.e. until the receiver has obtained synchronization to the uplink signal.
