  • Publication number: 20230143056
    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.

  • Publication number: 20230062978
    Abstract: A delay doppler domain transformation can be used to estimate characteristics of a channel between a base station and a user equipment or alternatively, between the user equipment and another user equipment. Thus, the velocity and the distance position of the user equipment can be calculated. For example, a signal received in the time-frequency domain, can be converted to the delay doppler domain by the base station. In response to the conversion, the base station can estimate the velocity of the user equipment. The velocity can be utilized by various applications. For example, the velocity can be utilized to alert the other user equipment to the location or an anticipated location of the user equipment.

  • Patent number: 11588923
    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.
