Abstract
Channel reservation systems and methods are disclosed herein, which schedule transmissions on a shared radio medium that is shared by a plurality of licensed network operators. In embodiments, priority access is pre-assigned to the network and the method determines whether to send a transmission based at least on the transmitter's priority class as compared to another transmitter's priority class and to which transmitter the time slot of a signal is dedicated. In embodiments, priority access may not be preassigned to the network and pre-grants may be used in conjunction with CR-Ts and CR-Rs to determine whether a transmitter transmits.
Claims18
A channel reservation method comprising:
- detecting, by a first base station of a plurality of base stations sharing access to a shared radio medium of a network that is shared by a plurality of licensed network operators, transmission of one or more channel reservation signals, between a second base station of the plurality of base stations and a user equipment (UE) associated with the second base station, during a channel reservation hand-shaking operation conducted between the second base station and the UE;
- and
- refraining, by the first base station, from scheduling transmissions on the shared radio medium based on the detecting the one or more channel reservation signals of the channel reservation hand-shaking operation to reduce contention of access to the shared radio medium.
A channel reservation system comprising:
- a plurality of devices that share access to a shared radio medium that is shared by a plurality of licensed network operators, wherein a first transmitting device of the plurality of transmitting devices is configured to detect transmission of one or more channel reservation signals, between a second transmitting device of the plurality of transmitting devices and a receiving device associated with the second transmitting device, during a channel reservation hand-shaking operation conducted between the second transmitting device and the receiving device, and wherein the first transmitting device is further configured to refrain from scheduling transmissions on the shared radio medium based on the detecting the one or more channel reservation signals of the channel reservation hand-shaking operation to reduce contention of access to the shared radio medium.
A non-transitory computer-readable medium having program code recorded thereon, which causes channel reservation, the program code comprising:
- code for detecting, by a first base station of a plurality of base stations sharing access to a shared radio medium of a network that is shared by a plurality of licensed network operators, transmission of one or more channel reservation signals, between a second base station of the plurality of base stations and a user equipment (UE) associated with the second base station, during a channel reservation hand-shaking operation conducted between the second base station and the UE;
- and
- code for refraining, by the first base station, from scheduling transmissions on the shared radio medium based on the detecting the one or more channel reservation signals of the channel reservation hand-shaking operation to reduce contention of access to the shared radio medium.
