Device, Network, and Method for Wideband LTE with Virtual (Baseband) Carrier Aggregation

摘要

Methods for wireless communications over a wideband carrier are provided. Time-frequency resources of the wideband carrier within a transmission time interval are divided into multiple time-frequency resource blocks. Each of the time-frequency resource blocks corresponds to a group of contiguous subcarriers of the wideband carrier and orthogonal frequency division multiplexing symbols. Data streams may be scheduled to be transmitted in different time-frequency resource blocks, and may be destined for different user equipments or the same user equipment. Baseband processing operations may be performed on data streams scheduled in different time-frequency resource blocks independently from one another. Separate control channels or one common control channel may be configured for data transmissions in different time-frequency resource blocks.

主权项

1. A method for wireless communications over a carrier, comprising:
performing, by a device, baseband processing on a first data stream to generate a first baseband signal, the first baseband signal being assigned to be transmitted over a first group of contiguous subcarriers in the carrier within a transmission time interval (TTI); performing, by the device, baseband processing on a second data stream, independently from the first data stream, to generate a second baseband signal, the second baseband signal being assigned to be transmitted over a second group of contiguous subcarriers in the carrier within the TTI, the second group of contiguous subcarriers different from the first group of contiguous subcarriers; and transmitting the first baseband signal and the second baseband signal over the carrier.
