  • Publication number: 20190320393
    Abstract: Some wireless communications systems may support mobile broadband (MBB) communications and low latency communications. To facilitate low latency communications, a base station may assign resources allocated for an MBB transmission for a low latency transmission. As described herein, to limit interference between an MBB transmission and a low latency transmission while maximizing the chances that the MBB transmission is received, an MBB user equipment (UE) may be configured to adjust a transmit power for the MBB transmission to limit the impact on a low latency transmission without preempting the MBB transmission. However, if the MBB UE is unable to adjust the transmit power for the MBB transmission prior to the MBB transmission, the MBB UE may determine whether to drop a portion of the MBB transmission on the resources assigned for the low latency transmission (e.g., based on whether a received power of the MBB transmission exceeds a threshold).

  • Publication number: 20190319698
    Abstract: A UE may determine a frame structure for narrowband communications, the frame structure corresponding to one frame structure from a group of TDD frame structures of different downlink and uplink subframe configurations. The UE receives configuration information indicating a first carrier to monitor for a BCH and/or a SIB1. Then, the UE receives a PSS, an SSS, and the BCH and/or the SIB1 using the frame structure determined for the narrowband communications. The first carrier that is used to receive the BCH and/or the SIB1 may be different from a second carrier used to receive one or more of the PSS or the SSS.

  • Publication number: 20190313357
    Abstract: Methods, systems, devices, and apparatuses for wireless communications are described that support techniques for initial access in wireless systems. Generally, the described techniques provide for communicating satellite information to simplify initial access procedures. A wireless communications system may signal relevant information (e.g., Doppler information or propagation delay information) associated with communications through a satellite to mobile terminals (e.g., user equipment (UEs)). The mobile terminals may utilize the relevant information to generate an uplink transmission (e.g., a random access message or an initial access message) that compensates for the Doppler shift and propagation delay that may be experienced by communications between the mobile terminals and the satellite.
