The secondary station transmits a preamble (102) to the primary station.
In a radio communication system comprising a primary station (100) and a secondary station (110), the primary station is able to employ one of a plurality of transmission schemes for transmissions to the secondary station.
The primary station can instruct the secondary station which of the plurality of rates it should use.
The control sub-channel connects the secondary station to the primary station serving the macro cell while the data sub-channel connects the secondary station to the primary station serving the pico cell.
The power offsets may be signalled to the primary station by the secondary station.
The primary station (2) and the secondary station (4) are coupled to each other via a transmission medium (14).
The primary station is arranged for determining a free channel list comprising the channels which are not used by any of the secondary stations to transmit information to the primary station.
The primary station then measures the quality of the received reference signal (316).
If the secondary station stops using the channel, the primary station will include said channel again in the free channel list.
Described is a transmission system comprising at least one primary station (2) and at least one secondary station (4).
In this way, the primary station (2) can determine the ability of the secondary station (4) to handle unsolicited grants.
This enables the optimum primary station for transmission of data to the secondary station (110) to be selected.
A method of operating a radio communication system uses a random access channel to enable a secondary station to transmit a message to a primary station.
The values of one or more metrics may be signalled to the secondary station by a primary station or vice-versa.
The initiating station transmits one or more SS feedback frames to the responding stations within the one SS slot to indicate an antenna configuration to the responding stations for communication with the initiating station.
The length of the measurement period may be signalled by the primary station or determined directly by the secondary station.
The primary station 2 transmits data signals 5 via the communication satellite 3 to the secondary station 4.
Each SS frame contains an indication to the initiating station of an antenna configuration for communication with the responding station.
A radio communication system has a random access channel for the transmission of data (214) from a secondary station to a primary station.
A radio communication system has a random access channel for the transmission of data (214) from a secondary station to a primary station.
