  • Patent number: 10419171
    Abstract: A BS may transmit a first signal using a first group of one or more tones, transmit a second signal using a second group of one or more tones, and transmit a third signal using a third group of one or more tones in a GB between the first and second groups of tones. In one example, the transmitting comprises controlling a transmit power of at least one tone of the third group of one or more tones in the GB. The at least one tone of the third group of tones is on a different frequency grid than the first group of one or more tones or the second group of one or more tones. A UE may perform corresponding transmit power control operations for UL transmissions in a GB.

  • Patent number: 10419244
    Abstract: Aspects of the present disclosure disclose techniques for implementing a wideband reference signal to improve the narrowband channel estimation performance associated with narrowband demodulation reference signal (DMRS) for the data channel in NR communications. Specifically, because the wideband reference signal may occupy wider bandwidth than the DMRS, the channel estimation realized may be more accurate than solely relying on the narrowband DMRS. In some examples, the wideband reference signal, which may be control reference signals (CRS), channel state information (CSI) reference signal (CSI-RS) in downlink or uplink sounding reference signal (SRS), may be associated with a corresponding narrowband DMRS in a data channel. The wideband reference signal may be either included in the control channel region or the data channel region.

  • Patent number: 10412632
    Abstract: Dynamically adaptive numerologies for ultra-reliable low-latency communications (URLLC) are discussed in which a base station may determine performance characteristics for each user equipment (UE) that it serves, in addition to detecting any fluctuations in system loading at the base station. Based on this information, the base may be select for each of the served UEs an adapted numerology that provides an optimized set of configurations that assist the communications between the base station and each UE to meet the strict parameters for URLLC. Once selected, the base station signals the selected adapted numerology to the UEs either through broadcast or UE-specific communications.

  • Patent number: 10405278
    Abstract: The disclosure relates in some aspects to an energy-aware architecture that supports a low power scheduling mode. For example, a media access control (MAC) architecture for a base station (e.g., an enhanced Node B) and associated access terminals (e.g., UEs) can take the power needs of the access terminals into account when scheduling the access terminals. In some aspects, an access terminal may support a particular frame structure for a low power mode. Accordingly, scheduling of the access terminal may include use of the particular frame structure during low power mode.
