  • Publication number: 20190380127
    Abstract: Methods, systems, and devices for wireless communication are described that provide for uplink channel multiplexing and waveform selection. Uplink channels to be transmitted from one or more user equipment (UEs) to a base station are multiplexed together or separately into an uplink subframe. Each UE is capable of using different waveforms to transmit different channels. Reference signals are communicated according to an RS pattern, which is symmetric across uplink and downlink channels.

  • Publication number: 20190379437
    Abstract: Methods, systems, and devices for wireless communication are described that support a low peak-to-average power ratio (PAPR) precoded reference signal design for multiple-input, multiple-output (MIMO) transmissions. A user equipment (UE) may identify multiple sets of symbols associated with different reference signal waveforms, where each reference signal waveform may be associated with a low PAPR. In some cases, different single-carrier reference signal waveforms may be mapped to subsets of frequency resources through frequency division multiplexing (FDM) for a transmission on a single antenna. However, the addition of single-carrier waveforms through FDM for a transmission via an antenna may result in an uplink transmission having a high PAPR (e.g., as compared to single-carrier waveforms). The UE may reduce the PAPR of the uplink transmission by multiplexing the reference signal waveforms in the time domain (e.g., using time division multiplexing (TDM)).

  • Patent number: 10506578
    Abstract: This disclosure relates to techniques for a base station (BS) to configure default and supplementary sync signals (SS) at sub-band bandwidths in a wireless communication system. The supplementary SS may be configured in response to a determination that the BS is in wireless communications with a UE using a single narrow band radio-frequency chain. The BS may configure the supplementary SS to be proximate in frequency to a PDCCH search space currently in use by the UE. The default SS may be configured to support initial access and may have a shorter periodicity, while the supplementary SS may be configured to not support initial access and may have a longer periodicity. The BS may additionally or alternatively configure a tracking reference signal (RS), wherein the tracking RS is configured on-demand based on a current network load of the BS.

  • Patent number: 10498506
    Abstract: Multiple-input, multiple-output (MIMO) devices and non-MIMO devices may implement a flexible comb-based design for transmission of reference signals, such as demodulation reference signals (DMRSs). User equipment (UEs) of different ranks may use the flexible comb-based design to transmit the reference signals in a common comb pattern within an allocated bandwidth. UEs using as many antenna ports as combs in the common comb pattern may transmit a different reference signal using a different antenna port over each comb, while UEs using fewer antenna ports than combs may concatenate combs, so that the UEs may transmit a reference signal using a single antenna port over multiple combs. Using the flexible comb-based design, a base station may be capable of better manage inter-cell interference and multiplexing of different rank UEs in shared resource blocks (RBs) may be supported.

  • Publication number: 20190364454
    Abstract: Signaling strategies for an advanced receiver with interference cancellation (IC) and suppression is discussed. Upon enablement of an advanced interference cancellation procedure according to the disclosure, transmitters within the enabled area transmit according to transmission restriction configurations that provide transmission limits based on either frequency, time, or scheduling. The restrictions on the transmitters reduces the complexity of processing by neighboring advanced receivers for cancellation of interference from the restricted transmitters. At the advanced receiver, transmission information, such as scheduling, reference signal (RS), resource block (RB) allocation, and the like, may either be determined through blind detection or received directly through signaling. The advanced receiver may use this transmission information associated with each interfering signal to detect, decode, and subtract the interfering signals from the received transmissions.

  • Patent number: 10477475
    Abstract: A wireless communication device (UE) may receive control indicator information (CII) indicating whether one or more candidate physical control channels (PCCs) are available to the UE for decoding. The UE may perform respective blind decoding if the CII indicates that the one or more candidate PCCs are available, to decode a respective PCC intended for the UE. The UE may receive the CII in the same slot in which PCCs are transmitted, or it may receive the CII in another slot, which may be a narrowband slot. The UE may receive the PCCs in the same slot in which corresponding physical data channels (PDCs) are transmitted, or it may receive the PCCs in another slot, e.g. a slot immediately preceding the slot in which the corresponding PDCs are transmitted. By eliminating unnecessary blind decoding and receiving the CII over narrowband, power consumption of the UE may be greatly reduced.
