Title:
RESOURCE BLOCK WAVEFORM TRANSMISSION STRUCTURES FOR UPLINK COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2018/126870
Kind Code:
A1
Abstract:
Methods and apparatus are provided for implementing waveform transmission structures for uplink data transmission of a radio burst between a UE and a base station in a telecommunications network. The radio burst includes a plurality of Orthogonal Frequency Division Multiplex (OFDM) symbols, each OFDM symbol covers an available frequency bandwidth comprising a plurality of contiguous resource blocks, RBs, spanning the available frequency bandwidth. A plurality of modulated symbols are divided into multiple groups of modulated symbols, each group of modulated symbols comprising a number of modulated symbols. Each group of modulated symbols is assigned to a different OFDM symbol of the radio burst. Various configurations for pre-coding the groups of modulated symbols with multiple or single DFTs, afterwhich subcarriers associated with the pre-coded modulated symbols are mapped to multiple RBs of the plurality of contiguous RBs of one or more OFDM symbols, where at least one of the RBs are non-contiguous with at least one other RB of the multiple RBs. Similarly, without a DFT subcarriers associated with the groups of modulated symbols are mapped to multiple RBs associated with the OFDM symbols. Transmitting the data based on the mapped RBs.
