Abstract: Acquisition and tracking modes for a mobile device assisted multilateration based localization are disclosed. A relative time difference is determined between a positioning reference cell and at least two other detectable positioning cells. A reference signal of a positioning cell is detected to determine timing of a detectable positioning cell by either applying sliding window approach to acquire the positioning cell or a single window approach to track the positioning cell. The sliding window approach within a search window is applied to acquire the positioning cell when a coarse timing of the positioning cell has not yet been achieved. A single window approach is applied to track the positioning cell when a coarse timing of the positioning cell has been achieved or when the search window is not larger than a capture range capability of the mobile device.

Abstract: A method and apparatus for receive beam-forming in an analog domain. A user equipment may perform channel estimation for obtaining a set of channel responses for a plurality of antennas of the UE. The UE may determine a beamforming codeword for receive beamforming based on the set of channel responses. The UE may apply a training codeword to the received signal in analog domain. The training codeword includes phase adjustment coefficients for each antenna and a different training codeword may be applied for each channel observation. The UE may measure a metric for at least one candidate codeword based on the set of channel responses and determine the beamforming codeword based on the metric.

Abstract: The present disclosure relates to a method for blind decoding a signal in a decoder of a mobile device. The method comprises receiving a channel coded signal; testing a plurality of hypotheses for the decoder that are not related to channel decoding by decoding the channel coded signal to generate a hypothesis specific decoded, channel coded signal and correlating a local channel coded reference sequence against a presumed corresponding section of the hypothesis specific decoded, channel coded signal for each of the plurality of hypotheses to generate a plurality of test results. The method further comprises determining a best hypothesis based on the plurality of test results and channel decoding a hypothesis specific decoded, channel coded signal for the best hypothesis to generate a channel decoded signal.

Abstract: A communication device and method to detect a sidelink identification from a second device for device to device, or sidelink, communication by performing a series of correlations using the demodulation reference signal and a set of demodulation reference templates stored in the memory component of the communication device. The communication device is further configured to reduce the computational complexity of the correlation procedure in the sidelink identification detection process by reducing the number of templates that need to be correlated with the demodulation reference signal and by reducing the number of complex-value multiplications of the correlation process.

The processor can determine, for each of the eNBs, a time of arrival (TOA) of the one or more RSs of each of the plurality of distinct types of RSs; and compute, for each of the eNBs, a reference signal time difference (RSTD) based at least in part on the TOAs of the one or more RSs of each of the plurality of distinct types of RSs. The transmitter circuitry can transmit the RSTD computed for each of the eNBs.

Abstract: Provided herein are a method and an apparatus for blind detection of Physical Downlink Control Channel (PDCCH) and Physical Downlink Shared Channel (PDSCH) using UE-specific reference signals. In an embodiment, the disclosure provides an apparatus for a UE, comprising circuitry configured to: measure a UE-specific Demodulation Reference Signal (DMRS) associated with a PDCCH; compute a first measurement metric M1 based on the UE-specific DMRS associated with the PDCCH before decoding the PDCCH; decode the PDCCH based on the first measurement metric M1; and decode PDSCH based on the decoded PDCCH. The disclosure may further, based on the corresponding PDCCH DMRS and/or PDSCH DMRS, determine if a PDSCH grant in a decoded PDCCH is valid or not, detect a repeated PDSCH grant in a slot, and detect cross-slot DMRS phase continuity between continuous slots.
