  • Patent number: 10804992
    Abstract: In one aspect of this disclosure, a transceiver obtains and transmits a CSI status indicator. In one example, the CSI status indicator indicates that previously reported CSI is outdated and/or that a new CSI report is available at the transceiver. In some embodiments, the transceiver generates or transmits the CSI status indicator according to a particular configuration, which may be set by a supporting wireless communication network. The configuration may include criteria on when to transmit the CSI status indicator, such as configuration criteria indicating that the transceiver should transmit the CSI status indicator responsive to completing its determination of a full-dimension beamforming matrix to be used for controlling beamforming towards the transceiver. The transceiver comprises, for example, a wireless device operating within a wireless communication network and the CSI status indicator corresponds to the status of downlink CSI.

  • Patent number: 10785606
    Abstract: In certain embodiments, a method for use in a network node comprises sending a control information message to at least one wireless device that is in idle mode. The message comprises a mapping that maps a quasi co-location (QCL) assumption to a multicast transmission or multicast channel. For example, in certain embodiments, the multicast transmission or multicast channel is associated with a temporary multicast group indicator (TMGI), and the mapping maps the QCL assumption to the TMGI. The control information message causes the at least one wireless device to use the QCL assumption to decode the multicast transmission or multicast channel while in idle mode.

  • Patent number: 10779186
    Abstract: Various embodiments disclosed herein provide for a dynamic access slice pooling system with software defined network (SDN) controlled capabilities in a 5G wireless communications system. A radio access network device can have one or more slices instantiated on the device that facilitate various services being requested by user equipment devices. A slice can have one or more virtual network functions that are specialized for particular services. When a user equipment device requests a service, the service can be assigned to a slice based on the type of service being requested. If the type of slice associated with the service is not currently operational, the SDN controller on the radio access network device can instantiate a new slice with the virtual network functions selected for the service being requested.

  • Patent number: 10771374
    Abstract: A physical layer chip of a first physical port of a network device receives a packet and sends a first time stamp and the packet to a Media Access Control (MAC) chip of the first physical port. The MAC chip of the first physical port adds the first time stamp to the packet and sends the packet. A MAC chip of a second physical port receives the packet, extracts the first time stamp of the packet, and sends the packet to a physical layer chip of the second physical port. The MAC chip of the second physical port receives a second time stamp of the packet. The network device calculates a processing delay for the packet. The processing delay is a value obtained by subtracting the first time stamp from the second time stamp.

The in-band backhaul may be transmitted in a high-capacity layer of the LDM signal carrying or in a separate timeslot. Transmitter-specific signature signals may be used for loopback and forward channel estimation at the relay transmitter. The in-band backhaul may also carry service data for devices in a different network.

  • Patent number: 10756785
    Abstract: A radio network sub-tiles reference signals (RSs) within a set of resource elements (REs) such that each sub-tiled RS occupies less than a time and/or frequency and/or power extent of its respective RE. The set of REs are dispersed across both frequency bins and time slots according to a pre-defined grid; and transmitted. The user equipment (UE) uses that pre-defined grid to locate within that transmission the set of dispersed REs. The UE accumulates and combines at least one subset of the sub-tiled RSs and estimates therefrom a quality; then reports uplink an indication of that estimated quality. Examples of the RSs include channel state information RSs, beam RSs and beam refinement RSs. Advantages are particularly relevant for 5G new radio systems.

  • Patent number: 10715600
    Abstract: A hub is connected to first and second networks where first-type and second-type frames are transmitted following first and second communication protocols. The hub sequentially receives each of the first-type and second-type frames, and stores data in first and second reception buffers. If the destination of data stored in the first and second reception buffers is the first network, the hub stores the data in a first transmission buffer. If the destination is the second network, the hub stores the data in a second transmission buffer. If the first transmission buffer is a priority transmission buffer, the hub transmits first yet-to-be-transmitted data in the first transmission buffer with priority. If the second transmission buffer is the priority transmission buffer, the hub transmits second yet-to-be-transmitted data in the second transmission buffer with priority.
