Radio access networks in which remote units are configured to perform at least some baseband processing
First Claim
1. A communication system comprising:
- remote units to communicate with mobile devices using radio frequency (RF) signals, the RF signals including information destined for, or originating from, at least one of the mobile devices, and wherein the remote units comprise radio frequency transceivers to communicate with the mobile devices;
a controller comprising a real-time scheduler configured to assign airlink resources to the mobile devices for communication, wherein the controller is configured to perform at least some baseband processing;
wherein the remote units are configured to perform at least some baseband processing, the at least some baseband processing performed at the remote units comprises receiving and extracting the information on an uplink control channel; and
wherein the at least some baseband processing performed at the controller comprises setting periods and phases for transmissions from one or more of the mobile devices, based on at least one location of the one or more mobile devices, so that transmissions from the one or more of the mobile devices do not overlap with transmissions of one or more other of the mobile devices.

Abstract
An example communication system in a cellular network comprises: a processing system comprising a controller and remote units, with the remote units being configured to communicate with the controller and to communicate with mobile devices within a communication cell of the cellular network. At least part of the processing system is configured to perform operations comprising: estimating signal strength experienced by all or some of the mobile devices; identifying, based at least on the signal strength, one or more of the mobile devices that can be scheduled for communication with one or more of the remote units in the communication cell on a same airlink resource; and scheduling the communication.

12. A method used in a communication network, the communication network comprising a controller and radio units, the radio units being configured to communicate wirelessly with the controller and to communicate with mobile devices, the method comprising:
-
performing at least some baseband processing at the controller, wherein the at least some baseband processing performed at the controller comprises setting periods and phases for transmissions from one or more of the mobile devices, based on at least one location of the one or more mobile devices, so that transmissions from the one or more of the mobile devices do not overlap with transmissions of one or more other of the mobile devices; performing at least some baseband processing at the remote units, wherein the at least some baseband processing performed at the remote units comprises receiving and extracting the information on an uplink control channel. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
