Abstract
Disclosed is a method, performed by a network node, for radio resource pre-reservation for communication of a first wireless device in an unlicensed channel. The method comprises determining an additional spectrum resource allocable for communication based on a successful clear channel assessment procedure conducted by the network node. The additional spectrum resource is different from a first resource used for ongoing communication with the first wireless device. The method comprises transmitting, to the first wireless device, control signalling indicative of the additional spectrum resource.
Claims20
A method, performed by a network node, for radio resource pre-reservation for communication of a first wireless device in an unlicensed channel, the method comprising:
- determining an additional spectrum resource allocable for communication associated with a successful clear channel assessment procedure initiated by the network node, wherein the additional spectrum resource is different from a first resource used for ongoing communication with the first wireless device;
- and
- transmitting, to the first wireless device, control signaling indicative of the additional spectrum resource to provide to the first wireless device the additional spectrum resource without a requirement of the wireless device initiating a clear channel assessment,
- wherein the additional spectrum resource is on an active bandwidth part or on a configured bandwidth part different from an active bandwidth part.
A method, performed by a wireless device, the method comprising:
- receiving, from a network node, control signaling indicative of an additional spectrum resource associated with a successful clear channel assessment initiated by the network node, wherein the additional spectrum resource is different from a first resource used for ongoing communication between the wireless device and the network node, wherein the additional spectrum resource provides to the wireless device an additional amount of spectrum resources without a requirement of the wireless device initiating a clear channel assessment, wherein the additional spectrum resource is on an active bandwidth part or is on a configured bandwidth part different from an active bandwidth part.
A method, performed by a wireless device, the method comprising:
- receiving, from a network node, control signaling indicating to the wireless device to use an additional spectrum resource to perform an uplink (UL) transmission, the additional resource being associated with a successful clear channel assessment initiated by the network node, wherein the additional spectrum resource is different from a first resource used for ongoing communication between the wireless device and the network node, wherein the additional spectrum resource provides to the wireless device an additional amount of spectrum resources without a requirement of the wireless device initiating a clear channel assessment, wherein the additional spectrum resource is on an active bandwidth part or on a configured bandwidth part different from an active bandwidth part.
