Abstract
A base station for providing flexible data rate transmission in a telecommunications system. The base station comprises an interface coupled to a signal processor coupled to a transmitter. The interface receives an incoming data stream. The signal processor receives the incoming data stream from the receiver and selects an operating downlink chip rate from at least two chip rates. The signal processor selects a spreading factor and spreads the incoming data stream into a spread data stream with a channelization code. The transmitter, receives the spread data stream from the signal processor and transmits the spread data stream over an air interface.

A base station for providing flexible data rate transmission in a telecommunications system comprising:
- an interface operable to receive an incoming data stream;
- a signal processor coupled to the interface, the signal processor operable to:
- receive the incoming data stream from the interface;
- select an operating downlink chip rate from at least two chip rates;
- select a spreading factor;
- and
- spread the incoming data stream into a spread data stream with a channelization code;
- and
- a transmitter coupled to the signal processor, the transmitter operable to receive the spread data stream from the signal processor and transmit the spread data stream over an air interface.
A method of providing flexible data rate transmission in a telecommunication system, comprising:
- receiving an incoming data stream;
- selecting an operating chip rate from at least two chip rates;
- selecting a spreading factor;
- and
- spreading the incoming data stream into a spread data stream with a channelization code.
The method of 17, further comprising selecting a number of slots, NSR, as:
- if p=2i, NSR=NS,
- 17 if p = 2 i + 1 , N S R = N S × 2 i p .
A user equipment for providing flexible data rate transmission in a telecommunications system comprising:
- an interface operable to receive an incoming data stream;
- a signal processor coupled to the interface, the signal processor operable to:
- receive the incoming data stream from the interface;
- select an operating uplink chip rate from at least two chip rates;
- select a spreading factor;
- and
- spread the incoming data stream into a spread data stream with a channelization code;
