Transmission medium sharing in a wireless communications network
A method of enabling sharing of a transmission medium by a first node of a wireless communications network and at least one further node of the network, comprising at the first node, acquiring occupancy of a channel of the transmission medium for a chosen Channel Occupancy Time which is less than or equal to a Maximum Channel Occupancy Time, generating first medium information comprising first node identification data, generating second medium sharing information comprising first node channel occupancy expiration time data, transmitting the first medium sharing information, transmitting the second medium sharing information, at the further node, receiving the first medium sharing information, using the information to identify the first node and using the identification of the first node to determine when sharing of the channel with the first node is allowed, receiving the second medium sharing information, using the information to determine the expiration time of the occupancy of the channel by the first node and using the expiration time to determine when transmission on the channel by the further node is possible.
1. A method of enabling sharing of a transmission medium by a first node of a wireless communications network and a plurality of UEs of the wireless communications network, comprising:
at the first node,
generating first node identification data,
generating medium sharing information comprising first node channel occupancy expiration time data,
transmitting the first node identification data, and
transmitting the medium sharing information using a dedicated broadcast signal, and
at the plurality of UEs,
receiving the first node identification data,
receiving the medium sharing information, and
using the information to determine how long a channel may be used.
2. The method according to claim 1 , wherein the first node identification data comprises any of: a cell ID, and a Radio Network Temporary Identifier.
3. The method according to claim 1 , wherein the medium sharing information comprises: a priority class to obtain a chosen Channel Occupancy Time (COT).
4. The method according to claim 1 , wherein the first node is a UE.
5. The method according to claim 1 , wherein the first node transmits multiple transmissions of the medium sharing information.
6. The method according to claim 1 , wherein the first node is a base station.
