    Abstract: Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.

  • Patent number: 10355895
    Abstract: A distributed radio frequency communication system facilitates communication between a wireless terminal and a core network. The system includes a remote radio unit (RRU) coupled to at least one antenna to communicate with the wireless terminal. The RRU includes electronic circuitry to perform at least a first portion of a first-level protocol of a radio access network (RAN) for communicating between the wireless terminal and the core network. The system also includes a baseband unit (BBU) coupled to the core network, and configured to perform at least a second-level protocol of the RAN. A fronthaul link is coupled to the BBU and the RRU. The fronthaul link utilizes an adaptive fronthaul protocol for communication between the BBU and the RRU. The adaptive fronthaul protocol has provisions for adapting to conditions of the fronthaul link and radio network by changing the way data is communicated over the fronthaul link.

  • Patent number: 10356807
    Abstract: Techniques are described for wireless communication. A first method may include inserting, in a first transmission using a first radio access technology (RAT), a channel occupancy identifier for a second transmission using a second RAT. The first method may also include transmitting the first transmission having the channel occupancy identifier over an unlicensed radio frequency spectrum band. A second method may include receiving, at a receiver operated using a first RAT, a channel occupancy identifier for a transmission using a second RAT. The channel occupancy identifier may be received over an unlicensed radio frequency spectrum band. The second method may also include decoding the channel occupancy identifier to identify a backoff period, and refraining from accessing the unlicensed radio frequency spectrum band using the first RAT based at least in part on the identified backoff period.

  • Patent number: 10349429
    Abstract: A system and method for frequency redirection in a communication system. In one embodiment, an apparatus accesses a communication system using first system information associated with a first frequency providing a first radio measurement. The apparatus receives an instruction to evaluate at least one frequency, and performs a second radio measurement over a second frequency without reading second system information associated with the second frequency. The apparatus accesses the communication system using the second system information associated with the second frequency when the second radio measurement exceeds a threshold, and performs a third radio measurement over a third frequency when the second radio measurement is less than or equal to the threshold and without reading third system information associated with the third frequency.

  • Patent number: 10327156
    Abstract: A resource allocation method according to the present invention may comprise the steps of: allocating a signal of an external resource to a predetermined resource according to a preconfigured resource allocation frame structure by a first base station governing a first cell; allocating a signal of an internal resource to the resource according to the resource allocation frame structure by a second base station governing a second cell adjacent to the first cell; and frequency-hopping the signal of the internal resource by the second base station when the signal of the internal resource overlaps the signal of the external resource. Accordingly, proposed is a resource allocation method capable of stably receiving a signal even when a terminal moving in a dense small cell structure is located at a cell edge, that is, an inter-cell boundary area.

  • Patent number: 10230519
    Abstract: An example apparatus comprises a processor, a memory element, and a media access control (MAC) scheduler. The MAC scheduler is configured to implement a transmission-reception (T-R) coordination scheme among a plurality of cable modems in a cable network, wherein the cable modems are categorized into interference groups. The MAC scheduler is further configured to assign one or more of the interference groups to at least one transmission group based upon predetermined criteria; and determine an upstream bandwidth constraint and downstream bandwidth constraint for the at least one transmission group, wherein the upstream bandwidth constraint and downstream bandwidth constraint is implemented by proportionally modifying an allocated upstream bandwidth and an allocated downstream bandwidth for the at least one transmission group to require that the sum of the allocated upstream bandwidth and the allocated downstream bandwidth does not exceed a spectrum capacity for the at least one transmission group.
