This disclosure introduces an advancement to the error indication message to provide detailed information about errors in configurations that are arriving from the Layer 2 to the Layer 1. A method is disclosed, comprising: performing physical layer control (PHY) of a wireless signal at a Layer 1 (L1) software module; performing medium access control (MAC) of the wireless signal at a Layer 2 (L2) software module; providing an application programming interface between the L1 software module and the L2 software module for receiving L1 configuration messages and providing error codes to the L2 software module; receiving a L1 configuration message at a Layer 1 software module; and providing an enhanced error code progressively from a L1 software module to the Layer 2 (L2) software module.

A receiver performing a half cyclic prefix (CP) shift on received subframes is disclosed, comprising: an analog to digital conversion (ADC) module; a cyclic prefix (CP) removal module coupled to the ADC module configured to retain a portion of cyclic prefix samples; a fast Fourier transform (FFT) module configured to receive samples from the cyclic prefix removal module, and to perform a FFT procedure on the received samples using a FFT window, the FFT window being shifted ahead based on the retained portion of cyclic prefix samples, to output an orthogonal frequency division multiplexed (OFDM) symbol; and a rotation compensation module coupled to the FFT module, the rotation compensation module configured to perform phase de-rotation of the OFDM symbol.

Mitigation of negative delay via half CP shift

A method for measuring channel quality in a wireless transceiver is disclosed, comprising: receiving, at a wireless transceiver, an analog signal from a user equipment (UE); converting the analog signal to a plurality of digital samples at an analog to digital converter (ADC); performing a fast Fourier transform (FFT) on the plurality of digital samples to generate frequency domain samples; identifying an uplink demodulation reference signal (DMRS) symbol; performing channel estimation on the DMRS symbol to identify an estimate of channels; creating a noise covariance matrix from the estimate of channels; and deriving an interference measure from the noise covariance matrix.

Uplink measurements for wireless systems

An ingestion code generation architecture facilities making large and complex datasets available for processing by parallel processing clusters. The architecture generates a set of data ingestion interfaces through which the operator specifies characteristics of their dataset. After receiving the specifications, the architecture automatically samples the dataset, analyzes its structure, and generates program code to ingest the dataset. The architecture solves the technical challenges of making complex and extensive datasets readily available to the parallel processing cluster so that the cluster may successfully perform its specialized processing over the dataset.
