  • Patent number: 11363572
    Abstract: Methods, systems, and devices for wireless communication are described A user equipment (UE) and a base station may support switching from one waveform to another on uplink channels. For example, a UE and a base station may utilize both frequency division multiplexing (SC-FDM) waveform and an orthogonal frequency division multiplexing (OFDM) waveforms based on channel conditions and other factors. In some examples, a UE may switch for some uplink channels, and use a single waveform for other channels. For example, switching waveforms for channels that utilize frequency domain code division multiplexing (CDM) channel may interrupt the orthogonality of multiplexed transmissions. A UE may transition from one waveform to another either autonomously or based on an explicit indication from a base station. If a UE switches autonomously, it may send an indication of the transition to the serving base station.

    Abstract: Aspects of the present disclosure provide for opportunistic uplink transmissions within a slot. In some examples, after scheduling all regular uplink transmissions within a current slot, a base station (e.g., gNB) may identify a set of unused uplink resources within the current slot and generate and transmit unused resource information identifying the set of unused resources to the user equipment (UE) within the cell served by the base station. If a particular UE is configured to operate in an opportunistic mode, the UE may utilize the unused resource information to generate and transmit an opportunistic uplink transmission within the set of unused uplink resources.

  • Patent number: 11330545
    Abstract: In one aspect of the teachings herein, a transmitter transmits synchronization signals according to one or more defined transmission characteristics that enable a receiver to distinguish the type of transmitter and/or the type of carrier used to convey the synchronization signals. Different types of transmitters reuse at least some of the same synchronization signal sequences and generation algorithms, but use different transmission parameters to impart one or more recognizable characteristics to the transmitted synchronization signals. In turn, an appropriately configured receiver “knows” which characteristics are associated with which transmitter and/or carrier types. For example, wireless devices operating in a wireless communication network transmit device-generated synchronization signals that reuse at least some of the same sequences used by network base stations for the transmission of network synchronization signals.

  • Patent number: 11038656
    Abstract: The present disclosure generally relates to methods, and apparatus for implementing the methods, for using sequence based uplink control information in 5G New Radio wireless communications. The method may include a user equipment (UE) may construct a signal based at least on resource assignment information received from a base station. The resource assignment information received by the UE may indicate frequency resources, a base sequence index, and a shift index. In a non-limiting example, the resource assignment information may include frequency resource assignment information related to one or more clusters. In implementations in which the frequency resource information includes a plurality of clusters, each of the plurality of clusters use a different base sequence and may use the same or different cyclic shifts. These sequences may be multiplexed in a non-orthogonal manner. The UE may use the resource assignment information to transmit the constructed signal to the base station.

  • Patent number: 10893512
    Abstract: Apparatus and methods are provided for RE allocation for UCI on PUSCH. In one novel aspect, the UE encodes UCI for transmission on PUSCH in a NR network. The UE allocates UCI REs onto the PUSCH following one or more UCI RE allocation rules including (a) using same logical allocation patterns for both CP-OFDM waveforms and DFT-S-OFDM waveforms, (b) distributing the UCI REs across a time domain of the PUSCH, and (c) distributing the UCI REs across a frequency domain for CP-OFDM or across a virtual-time domain for DFT-S-OFDM. In one embodiment, the HARQ-ACK REs are distributed across the time domain as much as possible. In another embodiment, the allocation of the HARQ-ACK REs further involves calculating the number of HARQ REs dynamically for the HARQ ACK. The number of HARQ REs is based on a weighting parameter, which is either configured or obtained through system information.

  • Patent number: 10826656
    Abstract: A wireless communication base station apparatus prevents degradation of throughput of LTE terminals, even when LTE terminals and LTE+ terminals are present together. A setting section sets in each subframe a resource block in which is arranged a reference signal that is employed solely by LTE+ terminals, based on the pattern of arrangement of reference signals employed solely by LTE+ terminals. As to symbols that are mapped to antennas (110-1) to (110-4), an arrangement section arranges the characteristic cell reference signals employed by both LTE terminals and LTE+ terminals in all of the resource blocks in a single frame. In contrast, as to symbols that are mapped to antennas (110-5) to (110-8), the arrangement section arranges in some of the resource blocks, that are set in accordance with the setting results input from a setting section, the characteristic cell reference signals that are employed solely by the LTE+ terminals.
