摘要： A physical channel processor on a wireless device and method for precoding for spatial multiplexing in an open-loop multiple-input multiple-output (MIMO) mobile communication system is disclosed. The method comprises the operation of receiving an input vector block from a layer mapper. The input vector block includes user equipment-specific reference signals (UE-RSs) or data in a physical downlink shared channel (PDSCH). The operation of generating a large delay cyclic delay diversity (CDD) vector block from the input vector block using a precoder configured for large delay CDD on an antenna port follows. The data can be resource element mapped with UE-RSs or channel-state information reference signals (CSI-RSs) in a physical resource block (PRB).

摘要： Techniques for resource block allocation in a multi-user MIMO High Efficiency WLAN system are provided. Specifically, teachings that when taken alone or together, provide a device or a group of devices with an improved resource allocation for the reduction of usable tone waste, are presented. The present disclosure includes a system that provides a user with a technique allocating data tones prior to the encapsulation unit or overhead tones on a resource block unit. Further, the total allocated bandwidth can be reduced prior resource allocation to overcome modulation and coding scheme downgrading caused by severe puncturing. Alternatively, only band edge basic resource blocks are reduced to account for overhead tones which largely reside on band edges.

摘要： Embodiments of User Equipment (UE), an Evolved Node-B (eNB), and methods for channel quality indicator (CQI) feedback are disclosed herein. An aperiodic CQI type parameter received at the UE may indicate a CQI type for use in a determination of an aperiodic CQI based on signals received from the eNB. Channel-state information reference signals (CSI-RS) may be used when single-user multiple-input multiple-output (SU-MIMO) signals are received. Physical downlink shared channel (PDSCH) blocks may be used when multi-user multiple-input multiple-output (MU-MIMO) signals are received. The aperiodic CQI may be transmitted to the eNB as part of an aperiodic CQI measurement report. In addition, periodic CQI measurement reports may also be transmitted to the eNB and may include periodic CQIs that are based on CSI-RS received at the UE.
