Abstract: This disclosure describes techniques for creating a hybrid mesh of unlicensed wireless frequency bands between two or more vehicles communicating using an unlicensed wireless frequency band, and a massive MIMO base station communicating with the two or more vehicles using a licensed wireless frequency band. The hybrid mesh can be used to upload and download data from a vehicle in motion. The hybrid mesh can be formed via V2V connections between the vehicle and nearby vehicles. In other words, if a vehicle moves into a region outside the operating boundary of a 5G-NR massive MIMO base-station node, the vehicle can interact with other vehicles to generate a data pipeline using the unlicensed wireless frequency band from the vehicle the nearby vehicle, and using the licensed wireless frequency band from the nearby vehicle to the nearest, massive MIMO base station.

The uplink data is received, based on the DCI and via the unlicensed cell, starting at the starting position in the subframe and ending before the ending symbol. The reception is based on an LBT procedure indicating a clear channel before the starting position of the subframe. The uplink data is mapped, based at least on the starting position and the ending symbol, to resource elements corresponding to the resource blocks.

Abstract: A communication management resource receives channel selection information from any number of licensed entities to operate in a shared band. Assume that the communication management resource receives first channel selection information indicating channels of interest (or band partitions, bandwidth, bandwidth partitions, sub-band portions, sub-band segments, etc., of an available wireless spectrum or band) to a first entity licensed to wirelessly communicate in a wireless network. Further, the communication management resource receives second channel selection information indicating channels of interest to a second entity licensed to wirelessly communicate in the wireless network. Based on the first channel selection information and the second channel selection information, the communication management resource allocates wireless channels amongst the first entity and the second entity.

Abstract: The present technology is directed to a scalable solution for end-to-end performance delay measurement for Segment Routing Policies on both SR-MPLS and SRv6 data planes. The scalability of the solution stems from the use of distributed PM sessions along SR Policy ECMP paths. This is achieved by dividing the SR policy into smaller sections comprised of SPT trees or sub-paths, each of which is associated with a Root-Node. Downstream SID List TLVs may be used in Probe query messages for signaling SPT information to the Root-Nodes Alternatively, this SPT signaling may be accomplished by using a centralized controller. Root-Nodes are responsible for dynamically creating PM sessions and measuring delay metrics for their associated SPT tree section. The root-nodes then send the delay metrics for their local section to an ingress PE node or to a centralized controller using delay metric TLV field of the response message.
