  • Patent number: 10813043
    Abstract: Performing wireless transmissions over a unified air interface that span portions of both the primary band and the complementary band may provide improved throughput and spectral efficiency in next generation networks. Wireless transmissions spanning both the licensed and unlicensed spectrum carry data in different frame formats over the respective primary and complementary bands. For example, frames communicated over the primary band may have a different channel structure (e.g., different size, placement, orientation, etc.) than frames communicated over the complementary band. Wireless transmissions spanning the licensed and unlicensed spectrum may also utilize different access schemes and/or waveforms over the respective primary and complementary bands. Embodiment unified air interfaces may be dynamically configurable via software defined radio (SDR) signaling instructions.

  • Publication number: 20200329475
    Abstract: Signal processing complexity in fifth generation (5G) networks can be reduced by communicating wireless signals over self-contained partitions of a carrier such that the wireless transmission communicated over each self-contained partition of the carrier includes all physical control channel signaling required to decode data carried in a physical data channel of the partition. The control signaling may include resource assignment within the partition, modulation and coding scheme indication, reference signal configuration and retransmission information. In some embodiments, an anchor partition of a carrier is used to communicate initial access information for self-contained partitions of the carrier. The initial access information may include center-frequencies, bandwidths, and/or air interface configurations of the self-contained partitions. The anchor partition may also carry load indications associated with the self-contained partitions.

  • Publication number: 20200328923
    Abstract: A method and apparatus for improving channel estimation within an OFDM communication system. Channel estimation in OFDM is usually performed with the aid of pilot symbols. The pilot symbols are typically spaced in time and frequency. The set of frequencies and times at which pilot symbols are inserted is referred to as a pilot pattern. In some cases, the pilot pattern is a diagonal-shaped lattice, either regular or irregular. The method first interpolates in the direction of larger coherence (time or frequency). Using these measurements, the density of pilot symbols in the direction of faster change will be increased thereby improving channel estimation without increasing overhead. As such, the results of the first interpolating step can then be used to assist the interpolation in the dimension of smaller coherence (time or frequency).

  • Publication number: 20200322100
    Abstract: Systems and methods for early termination of feedback in respect of sidelink transmissions are provided. A first UE transmits at least one sidelink (SL) transmission of a first set of SL transmissions to a second UE, the first set of SL transmissions comprising an initial SL transmission and a set number of SL retransmissions. If no ACK is received, then the first UE transmits the set number of retransmissions. On the other hand, if an ACK is received, then the first UE transmits fewer than the set number of SL retransmissions when an ACK is received from the second UE before the set number of SL retransmissions has been completed. By transmitting fewer than all of the set number of SL retransmissions, resources can be freed up for other purposes. The approach may be used for SL configured grant transmission.

  • Publication number: 20200322939
    Abstract: Systems and methods for sidelink configuration are provided. A transmitting user equipment (UE) transmits configuration parameters relating to a sidelink transmission between the UE and a second UE via higher-layer signalling and then transmits the sidelink transmission to the second UE. The higher layer signalling is a layer above the sidelink transmission. The parameters may include feedback channel parameters or parameters for sidelink reference signal transmission by the second UE. The parameters may be selected by the transmitting UE, or they may be received initially from the network. The parameters may be part of a sidelink configured grant configuration (SL CG) signalled to the second UE. The sidelink transmission may be a configured-grant transmission to the second UE according to the SL CG configuration. The higher layer signalling may be PC5 signalling or RRC signaling.

  • Patent number: 10797764
    Abstract: The present invention employs a pilot scheme for frequency division multiple access (FDM) communication systems, such as single carrier FDM communication systems. A given transmit time interval will include numerous traffic symbols and two or more short pilot symbols, which are spaced apart from one another by at least one traffic symbol and will have a Fourier transform length that is less than the Fourier transform length of any given traffic symbol. Multiple transmitters will generate pilot information and modulate the pilot information onto sub-carriers of the short pilot symbols in an orthogonal manner. Each transmitter may use different sub-carriers within the time and frequency domain, which is encompassed by the short pilot symbols within the transmit time interval. Alternatively, each transmitter may uniquely encode the pilot information using a unique code division multiplexed code and modulate the encoded pilot information onto common sub-carriers of the short pilot symbols.
