11178641 · 2021-11-16 · ·

An embodiment of the present invention relates to a method for transmitting or receiving a signal associated with a platoon communication by a first terminal in wireless communication system, the method comprising the steps of: receiving group resource pool information of a terminal group moving in a platoon formation; selecting a sub-pool, which is to be used by the first terminal, in a group resource pool on the basis of the group resource pool information; and transmitting or receiving a signal to or from one or more terminals within the terminal group through the selected sub-pool.

Time multiplexed channel hopping for LLNs

In one embodiment, a device receives data indicative of a routing topology of a network. The network includes a root node and each node in the network has an associated network depth relative to the root. The device selects a first subset of timeslots from a slotframe of a communication schedule based on the network depth of a particular node in the network. The device selects a second subset of timeslots from the first subset, based on a media access control (MAC) address of the particular node. The device assigns the second subset of timeslots to the particular node for reception in the slotframe of the communication schedule. The device sends the communication schedule to one or more nodes in the network.

Methods and apparatus for efficient IP multicasting in a content delivery network
10200425 · 2019-02-05 · ·

Methods and apparatus for assigning physical channels in a content-based network. In an exemplary embodiment, the network comprises a cable television network having a plurality of cable modems, and the physical channels are assigned to the cable modems based at least in part on any multicast transmissions that may exist on the system. When two cable modems are receiving the same multicast transmission, the invention causes tuning of one or more of the cable modems to the same physical channel in order to limit the total number multicast transmissions on the network. Multicast transmissions typically comprise video or audio information, but other types of information may also be multicast according to the invention. In another embodiment, a multicast transmission list (containing a list of multicast transmissions and the corresponding physical channels) is sent to the set of cable modems. This list is used by the modems (or associated CPE) to manage channel allocation and tuning.

DISTRIBUTION OF A VIRTUAL NETWORK OPERATOR SUBSCRIPTION IN A SATELLITE SPOT-BEAM NETWORK

A system and method for bandwidth management for a Host Network Operator (HNO) is disclosed. The method including: providing shared beams shared by two or more of a plurality of Virtual Network Operators (VNOs), wherein each VNO has a subscription including a global bandwidth limit applicable for a flow control epoch for each VNO and a terminal subscription for each terminal associated with the respective VNO; aggregating, in the current flow control epoch, a demand and the terminal subscriptions of active terminals per shared beam per VNO; distributing, for each shared beam per VNO, the aggregated demand and active terminal subscriptions into a distribution bandwidth per shared beam per VNO, wherein the distribution bandwidth is based on the respective global bandwidth limit of the respective VNO; and proportionally balancing, for each shared beam, an oversubscription of the distribution bandwidths per shared beam per VNO based on the proportionalities of the global bandwidth limit of each VNO subscribing to the shared beam, to provide a proportional distribution bandwidth per shared beam per VNO.
