  • Patent number: 9658311
    Abstract: Disclosed herein, one embodiment of the disclosure is directed to a system, apparatus, and method for location estimation in the presence of multipath/non-line-of-sight (NLOS) conditions. Various methods have been contemplated to detect the level of multipath/NLOS propagation between two devices. A SNR variation method determines how the SNR of each chain/stream is varying over a time window in order to detect the chain/stream with least local scattering or multipath. A measure of coherence SNR is defined to measure the level of multipath/NLOS per-chain/stream. Moreover, since per-subcarrier SNR information is available at the one or both nodes, the coherence methods can be used on a per-subcarrier basis to detect multipath/NLOS for the entire channel, for the specific spatial stream or for the specific frequencies occupied by the subcarriers. Furthermore, a coherence bandwidth estimation method uses the SNR variation over subcarriers to detect the coherence bandwidth of the spatial stream.

  • Patent number: 9596638
    Abstract: Apparatus, system and methods for evaluating link quality within a cellular system. A user equipment (“UE”) is connected to a network, wherein the UE communicates data to the network on an uplink (“UL”) link. The UE determines a requested buffer size for a UL communication, determines a transport block size for the UL communication based on a primary set of allocation parameters, and compares the requested buffer size to the transport block size to determine if a data rate for the UL communication satisfies a threshold. When the data rate satisfies the threshold, the UE identifies the UL link as a good quality link and sends acceptable link quality feedback to the network. When the data rate does not satisfy the threshold, the UE performs a further action to test a quality of the UL link.

  • Patent number: 9596043
    Abstract: Provided are a quality prediction method and device for a physical downlink control channel of a long term evolution system. In the method, a target user equipment (UE) requiring physical downlink control channel (PDCCH) quality prediction is determined, and information reported by the target UE is received. According to the reported information, a prediction index of the target UE is determined, wherein the prediction index is a signal to interference plus noise ratio (SINR) of the control channel or an equivalent reception level (RPPDCCH) of the control channel. According to the SINR or the RPPDCCH, the PDCCH quality of the target UE is determined. The present document can be applied to provide more accurate and highly efficient control channel quality prediction for LTE users without adding measurement and signalling, thereby achieving the purpose of providing a quick and precise positioning basis for a control channel element (CCE) resource and power allocation algorithm of an Evolved Node B (eNodeB).

  • Patent number: 9591648
    Abstract: An example embodiment may involve defining an orthogonal frequency-division multiplexed (OFDM) wireless air interface that contains time-division multiplexed subframes. A primary signaling channel may be formed by modulation symbols that are statically allocated to fixed time positions of each subframe, and span contiguous subcarrier frequencies. A secondary signaling channel may be defined in the OFDM wireless air interface. The secondary signaling channel may be formed by modulation symbols that are dynamically allocated to time positions of one or more subcarrier frequencies, and span at least two consecutive subframes of the OFDM wireless air interface. A signaling message may be transmitted, on the primary signaling channel, to one or more WCDs. The signaling message may be transmitted in a first subframe of the consecutive subframes, and may identify the secondary signaling channel.
