  • Publication number: 20190253292
    Abstract: The middle subcarrier of the baseband OFDM signal of each numerology may need to be shifted appropriately with respect to other numerologies to comply with a nested grid. These shifts can be signalled to the UE with an associated overhead. Methods and systems are provided to reduce overhead for OFDM communication. Reduced overhead can translate into increased bandwidth for the system, and/or reduced power/battery consumption in the UE. A transmitter generates an OFDM signal associated with a first subcarrier spacing of a first numerology (?), a middle subcarrier frequency of a set of usable resource blocks (RBs) of the first numerology being offset from a carrier frequency by a first offset having a value (k0,x?) in units of subcarriers, the value of the first offset being defined by a specific formula. The transmitter transmits the OFDM signal according to the first subcarrier spacing and the first offset.

  • Publication number: 20190215847
    Abstract: A user equipment (UE) receives control signaling in a scheduling bandwidth part (BWP). The control signaling indicates switching from a first active BWP to a second active BWP or switching from a first active BWP pair to a second active BWP pair for the UE. The control signaling aligns with a time unit boundary, such as a slot boundary, that is associated with the scheduling BWP. In the event that a scheduled BWP for a UE has a different numerology than a scheduling BWP that is currently active for the UE, the UE could switch from the scheduling BWP to the scheduled BWP based on a control signaling monitoring periodicity of the scheduled BWP.

  • Publication number: 20190215216
    Abstract: Systems and methods are provided for configuring an alignment between various resource grids. A base station transmits alignment information between a first resource grid or a first transmission using the first resource grid, and a second resource grid and a third resource grid. The first resource grid uses a first sub-carrier spacing (SCS) from a first set of SCSs, the second resource grid uses a second SCS from a second set of SCSs, the third resource grid uses a third SCS from the second set of SCSs. The base station transmits a synchronization sequence block (SSB) using the first resource grid, and the base station transmits a first physical downlink shared channel (PDSCH) in assigned resource blocks using at least one of the second resource grid and the third resource grid. A user equipment receives the alignment information, and determines the resource grids based on the alignment information so as to be able to receive the transmitted resource blocks.

  • Publication number: 20190182307
    Abstract: Methods and devices are disclosed for encoding and transmitting data sequences for low data rate applications. An encoded data sequence is transformed and used to shape a multi-carrier pulse to create a narrow-band signal for transmission. Time domain tails of the narrow-band signal may be removed to decrease overhead. The data may be first encoded to create a sparse modulated data sequence. Multi-carrier pulse shaping may be carried out using frequency division multiplexing (FDM) or filter bank multi-carrier (FBMC) techniques. Alternatively, single carrier pulse shaping may be used to create the narrow-band signal.

  • Patent number: 10305645
    Abstract: A unified frame structure for filter bank multi-carrier (FBMC) and orthogonal frequency division multiplexed (OFDM) waveforms may allow FBMC and OFDM frames to be communicated over a common channel without significant inter-frame gaps. The unified frame structure may set an FBMC frame duration to an integer multiple of an OFDM frame element duration to enable alignment of FBMC frames and OFDM frames in the time domain. The unified frame structure may also map control channels in the FBMC and OFDM frames to common resource locations so that the respective control channels are aligned in the time and/or frequency domains. The unified frame structure may also share synchronization channels between FBMC and OFDM frames. Additionally, overhead in an FBMC time division duplexed (TDD) communications channel can be reduced by overlapping time windows appended to FBMC blocks.

  • Publication number: 20190150121
    Abstract: Methods and devices for configuring an initial active downlink bandwidth part as part of an initial access procedure are provided. In one provided method, a base station broadcasts a synchronization signal block (SSB) that includes a control resource set (CORESET) configuration index. The CORESET configuration index is one of a plurality of CORESET configuration indexes, each CORESET configuration index being associated with a respective configuration of a CORESET. Each configuration includes a CORESET frequency size, a CORESET time duration, and a frequency offset of the CORESET with respect to the SSB selected from a set of predefined frequency offsets. The initial active downlink bandwidth part is defined as having the same frequency location and bandwidth as the CORESET. The base station transmits, as part of a physical downlink control channel (PDCCH) within the CORESET, information indicating scheduling of remaining minimum system information (RMSI) in a physical downlink shared channel (PDSCH).

  • Patent number: 10098121
    Abstract: Methods and devices are disclosed for decoding multiple sparsely encoded data sequences in a wireless communications network. A received signal carrying multiple sparsely encoded data sequences is decoded by selecting a first plurality of the data sequences and performing multi-user decoding on the received signal to decode the first plurality of data sequences. Other data sequences are treated as noise. The plurality of data sequences is selected to meet a collision threshold for the multi-user decoding. Data sequences may be selected based on a collision contribution and signal quality metrics. A modified received signal is generated to remove signals associated with the multiple sparsely encoded data sequences which have been successfully decoded. The method may be performed for additional iterations to select a new plurality of data sequences, and perform the multi-user decoding on the modified received signal to decode additional data sequences, until a stopping condition is met.
