  • Patent number: 11223397
    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.

  • Patent number: 11212147
    Abstract: It is possible to reduce the implementation complexity associated with dynamic carrier configuration by defining overlapping sets of candidate numerologies for at least some carriers in the network. A common numerology is included in sets of candidate numerologies pre-associated with two different carriers. This reduces the amount of numerologies that need to be supported by the corresponding user equipments (UEs) and base stations, which in turn reduces the complexity of those devices, e.g., less complex hardware, protocol stacks, and software, lower storage and processing requirements, etc. The common numerology specifies a common subset of physical layer parameters for both carriers. In one example, the common numerology specifies the same sub-carrier frequency spacing and symbol duration for both carriers. The common numerology may further specify the same cyclic prefix (CP) length for symbols communicated over both carriers.

  • Publication number: 20210377860
    Abstract: The power requirements of user equipments (UEs) are expected to increase as their capabilities increase. Some power saving methods have previously been proposed, but are limited by the radio resource control (RRC) protocol and do not address the power consumption associated with having to transition between different RRC states. In some embodiments described herein, there are not different RRC states, but instead a single RRC state. Within that single RRC state, there are different modes of operation, e.g. a default low power operation mode and an enhanced power operation mode. In some embodiments, the UE switches from the default operation mode to the enhanced operation mode on an on-demand basis (e.g. based on the communication capability required by the UE), and then returns back to the default operation mode.

  • Publication number: 20210377842
    Abstract: Multiple communication paths are established for communications between a User Equipment (UE) and a wireless communication network, before switching between those paths is initiated. Signaling that includes an explicit indication that the UE is to switch between the multiple communication paths is transmitted to and received by at least the UE for which the multiple communication paths were established. Responsive to the explicit indication, communications are switched between the communication paths. At least one of the communication paths includes a relay path between the UE and the wireless communication network through another UE. Establishment of the multiple paths in advance of the switching may be useful in enabling fast switching with low latency and/or no traffic loss.

  • Patent number: 11178580
    Abstract: User Equipment (UE) mobility in Ultra Dense Networks (UDNs) is based on communication signal layers, which could include respective data streams in an Orthogonal Frequency Division Multiplexing (OFDM) domain, a code domain using respective codebooks, and/or a spatial domain, for example. A UE uses candidate layer decoding parameters in applying layer-based decoding to communication signals that it received from network nodes. Layers could be allocated to UEs and transition between network nodes as UEs move between different network service areas. Layers could instead be allocated to network nodes. Layer-based decoding provides for UE mobility without requiring explicit handover processing every time a UE moves between different service areas.

  • Patent number: 11177995
    Abstract: Aspects of the present application provide methods and devices for time domain implementation of a single carrier waveform such as single carrier quadrature amplitude modulation (QAM) DFT-s-OFDM and single carrier Offset QAM (OQAM). A time domain implementation allows flexible symbol lengths, lower implementation complexity as a large IDFT operation is not required in the time domain and support for variable cyclic prefix (CP) length. An OQAM implementation utilizes a pre-processing step to convert a K complex QAM symbol sequence into a 2K OQAM symbol sequence and generates a sequence for transmission in the time domain as opposed to the frequency domain.

  • Publication number: 20210344546
    Abstract: A system and method of DFT-S-OFDM modulation is provided that uses a set of frequency domain patterns. For a given transmitter, for a set of DFT-S-OFDM symbols, the frequency domain pattern changes according to a time domain hopping pattern. Advantageously, the time domain hopping patterns are defined to allow only a certain amount of overlap, for example for only one DFT-S-OFDM symbol, between any two time domain hopping patterns. This functions to reduce the effect of a collision, when two transmitters use the same frequency pattern, they will do so only for part of the overall transmission. Optionally, frequency domain spectral spreading is used in the transmitter. This can further reduce the PAPR. In the receiver, successive interference cancellation may be employed to reduce the effect of colliding transmissions.
