Abstract
Among other things, a communication system comprising at least one remote unit and at least one controller is described. The at least one remote unit exchanges radio frequency (RF) signals with mobile devices. Each RF signal comprises information destined for, or originating from, at least one of the mobile devices. The at least one controller is communicatively coupled to the at least one remote unit. All physical layer processing for an air interface is implemented in the at least one remote unit. All Media Access Control (MAC) layer processing for the air interface is implemented in the at least one controller.
Claims18
A communication system comprising:
- a plurality of remote units assigned to a cell, wherein the plurality of remote units exchange radio frequency (RF) signals with mobile devices using an air interface, each RF signal comprising information that is destined for, or originating from, at least one of the mobile devices;
- and
- at least one controller communicatively coupled to the plurality of remote units;
- wherein processing for the air interface is performed at the communication system, the processing comprising physical layer processing, Media Access Control (MAC) layer processing, and upper layer processing;
- wherein all the physical layer processing performed at the communication system for the air interface is implemented in the plurality of remote units;
- wherein all the MAC layer processing performed at the communication system for the air interface is implemented in the at least one controller.
A method performed at a communication system, comprising:
- exchanging, by a plurality of remote units assigned to a cell in the communication system, radio frequency (RF) signals with mobile devices using an air interface, each RF signal comprising information that is destined for, or received from, at least one of the mobile devices;
- and
- communicating baseband data between at least one controller in the communication system and the plurality of remote units;
- wherein processing for the air interface is performed at the communication system, the processing comprising physical layer processing, Media Access Control (MAC) layer processing, and upper layer processing;
- wherein all the physical layer processing performed at the communication system for the air interface is implemented in the plurality of remote units;
- wherein all the MAC layer processing performed at the communication system for the air interface is implemented in the at least one controller.
