  • Publication number: 20210111740
    Abstract: Aspects of the subject disclosure may include, for example, obtaining a received channel-encoded data block having information bits, a transmitted error-check value, and redundant code bits. The redundant code bits correspond to a channel code applied to the received channel-encoded data block prior to transmission via a communication channel. A channel code type is identified and responsive to it being systematic, the information bits and the transmitted error-check value are obtained without decoding according to the channel code. The received channel-encoded data block is checked according to the transmitted error-check value to obtain a result. Responsive to the result not indicating an error, extracting the information bits without decoding the received channel-encoded data block according to the channel code. Responsive to the result indicating an error, decoding the received channel-encoded data block according to the channel code to obtain decoded information bits. Other embodiments are disclosed.

  • Patent number: 10979891
    Abstract: In a 5G network, new radios (NR) can be deployed as a standalone radio access technology or as a non-standalone radio access technology assisted by another radio access technology. Long-term evolution (LTE), which is widely deployed can provide seamless coverage and uninterrupted connectivity, however NRs can provide significantly increased data rates or new services. However, the deployment of NR can be limited to hotspots under the footprint of LTE. Therefore, dual connectivity between LTE and NR can be utilized for non-standalone NR because control plane functions can be sent over LTE while the data plane can be managed on NR, allowing for simplified NR deployments where device support for both LTE and NR is available.

  • Publication number: 20210105078
    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: 20210105791
    Abstract: Facilitating a time-division multiplexing pattern-based solution for a dual-subscriber identity module with a single radio in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise obtaining, by a network device comprising a processor, multiple time-division multiplexing patterns applicable to a mobile device. The multiple time-division multiplexing patterns indicate respective repeating patterns of an on state and an off state of a defined identity of the mobile device. The method also can comprise facilitating, by the network device, a transmission, to the mobile device, of information indicative of the multiple time-division multiplexing patterns. In an example, the mobile device can be configured to operate with at least two subscriber identity modules.

  • Publication number: 20210105606
    Abstract: One subscriber identity module (SIM) can transmit data in active mode while another SIM is in an idle mode. However, paging for the SIM in idle mode can occur based on a discontinuous reception configuration (DRX) cycle of the active SIM. For example, when the DRX of the active SIM indicates that the active SIM is in an idle state, then the SIM that is currently in an idle state can send messages and vice versa. The DRX cycle information can be exchanged between a first core network and a second core network. Each core network can belong to the same or different mobile network operator and can have separate radio access networks (RAN) or share the RAN. The DRX cycle information and/or a time-division multiplexing (TDM) pattern can be exchanged over the air via a system information broadcast message.

  • Patent number: 10966137
    Abstract: The described technology is generally directed towards adaptively changing which transmission scheme a user equipment is to use based on a Doppler metric (e.g. Doppler frequency) as evaluated against a threshold Doppler value. A network instructs a user equipment to use a Rank-1 precoder cycling transmission scheme if the Doppler metric of user equipment is above a threshold value, or to use a closed loop MIMO transmission scheme if the user equipment has a Doppler metric below the threshold value. The network can instruct the user equipment via a suitable message, or by switching off TPMI and notifying the user equipment thereof.

  • Patent number: 10965786
    Abstract: Compression techniques can reduce the fronthaul throughput in split radio access network (RAN) architectures for next generation designs. Adaptive fixed-point mapping can reduce the throughput requirements between a baseband unit (DU) and a remote radio unit (RU). Thus, a bit or plurality of bits can indicate the type of data being passed over the fronthaul. Consequently, adaptive mapping between precoded downlink data and non-precoded downlink data suited to the type of data passed over the fronthaul can achieve high compression ratios.

  • Patent number: 10958511
    Abstract: In a 5G network, an integrated access and backhaul (IAB) deployment in a 5G network, can enable aggregation of multiple user equipment (UE) bearers into backhaul bearers based on factors such as route information of UE bearers and quality of service of UE bearers. Additionally, an adaptation layer can be configured to perform aggregation of data from UE bearers into backhaul bearers either above or below a radio link control layer. Thus, aggregation of data from UE bearers into backhaul bearers can be performed either above the RLC or below the RLC to take advantage of benefits from both options.

  • Publication number: 20210084519
    Abstract: Doppler metric data relating to a speed of a mobile device can be used by the mobile device to determine whether a speed threshold has been satisfied. If the speed threshold has been satisfied, then the mobile device can make a recommendation to a network node device to terminate closed-loop multiple input multiple output transmissions and to use a rank-1 precoder transmission. The network device can then decide how to proceed. Alternatively, the network device can change the transmission type based on a load threshold being determined to have been satisfied and the recommendation from the mobile device.

  • Patent number: 10951280
    Abstract: A low complexity multiple input multiple output transmitter that transmits a single codeword per channel is disclosed herein. Instead of sending multiple codewords per channel for transmissions that support higher data layer transmissions, the transmitter can send single codewords over multiple channels in order to improve spectral efficiency over a range of signal to interference plus noise ratios. For instance, if a downlink transmission to a user equipment (UE) has a rank of 4, capable of supporting 4 data layers, instead of sending 2 or more codewords over a single downlink control channel, the transmitter can schedule multiple control channels and transmit a single codeword per channel. The transmitter can also include in the signaling to the UE that the multi-codewords are included in multiple downlink control channels.
