  • Patent number: 11310799
    Abstract: Various embodiments disclosed herein provide for optimizing identification of a beam in a massive multiple-input multiple output (MIMO) system. The receiver device can select a beam to use for a transmission, and generate channel state information based on a selection of either a single stage beam selection process or a two stage beam selection process. According to an embodiment of the disclosure, the receiver can select which beam selection process to use based on the context of the receiver device. The receiver can select which beam selection process to use based on the long term signal to noise ratio, or the correlation metrics associated with the receiver and transmitter, or based on the path loss between the transmitter and receiver, or based on the location of the receiver relative to the transmitter.

  • Patent number: 11283517
    Abstract: The described technology is generally directed towards dynamic resource coordination that supports multi-hop based relaying for integrated access and backhaul (IAB) in New Radio (5G). Described is a technology in which an IAB node and a serving parent node use wireless signaling to dynamically adapt downlink and uplink resources used for access and backhaul links. An IAB node receives scheduling data from a parent node, configures a frame structure comprising mobile termination function subframes and distributed unit component subframes, and communicates data based on the frame structure. The parent node explicitly or implicitly indicates that a portion of the scheduling data is adaptable, e.g., sends a dynamic frame structure coordination message. In response, the IAB node can adapt the frame structure into a modified frame structure and can communicate further data based on the modified frame structure.

  • Publication number: 20220085903
    Abstract: The described technology is generally directed towards sharing a radio by multiple subscriber identities at a device. A time division multiplexing pattern at the device radio gives primary radio use to a first subscriber identity, while also providing time windows for radio use to a second subscriber identity. In response to a communication by the second subscriber identity, the time division multiplexing pattern can be changed to give the primary radio use to the second subscriber identity. Also, a radio resource control protocol can designate appropriate states for the different subscriber identities, designating the subscriber identity with primary radio use as connected, while the other subscriber identity is designated as inactive or idle.

  • Publication number: 20220060995
    Abstract: Various embodiments disclosed herein provide for a power control system in a multi-hop integrated access and backhaul network. In the multi-hop integrated access and backhaul network, a donor node can communicate with user equipment devices and relay nodes that have varying power levels; and to avoid receiving uplink transmissions with varying power levels which can impact automatic gain control systems and lower overall throughput, the power control system can manage the power levels of the relay node in order to reduce the difference in power levels. The power control system can schedule relay node devices to transmit uplink transmissions alongside user equipment devices that have a high signal strength; schedule relay nodes and user equipment devices to separate symbols within a time slot; and/or perform closed loop power control management at the relay node to reduce the power level for an uplink transmission.

  • Publication number: 20220060219
    Abstract: Various embodiments disclosed herein provide for a codeblock segmentation configuration system. A base station can configure the segmentation rate or segment size, which can control the number of codeblock segments a transport block is segmented into, based on the transmission reliability and predicted interference to a mobile device. An increased number of segments can improve throughput and efficiency when interference is low and signal to noise ratios are high, but can increase latency when interference is high and signal to noise is low. The base station can determine or predict transmission reliability based on the speed of mobile devices, the location and/or distance to the mobile device, as well as the long term signal to noise ratios.

  • Patent number: 11258485
    Abstract: Various embodiments disclosed herein provide for an enhanced timing advance scheme to support MU-MIMO in an integrated access and backhaul system. The timing advance scheme disclosed herein aligns the arrival time between backhaul links and access links to enable MU-MIMO gain at the receiver side. In the integrated access and backhaul system, which comprises distributed nodes, the timing advance offset for an access link transmission (a transmission to a node further away in hops from the core network, or to a user equipment device) can be modified by offsetting it with the timing advance of the backhaul link (e.g., from a parent node). This enables the arrival time for transmissions, both access link transmissions from the UE or child node, and backhaul link transmissions from a parent node to arrive at the same time.

  • Publication number: 20220038328
    Abstract: The described technology is generally directed towards dynamically changing which quadrature amplitude modulation (QAM) table a user equipment is to use based on channel quality information. A network schedules a user equipment with 256 QAM modulation if the user equipment recommends 256 QAM in the CQI report (and the scheduler decides to use 256 QAM for that particular user equipment). The network indicates to the user equipment that it has to use 256 QAM modulation and coding scheme (MCS) table and not the configured QAM MCS table while determining the scheduling parameters by decoding PDCCH.
