Abstract: A merchandise information generation and management platform based on the crowd sourcing participation introduces a comprehensive merchandise information to display and present a product and/or service. The comprehensive merchandise information includes: the attribute information, the purchasing address, the copywriting information, the tag information, and combinations thereof. The comprehensive merchandise information originates from a crowd sourcing user and it can be actively published, submitted, and shared by a crowd sourcing user and/or be actively obtained by the platform. To be used on the platform, the comprehensive merchandise information is reviewed and selected by a mechanism such as the crowd sourcing based use tagging, the crowd sourcing based two-way review, and the like.

Abstract: A method (300) for indoor positioning or navigation comprises obtaining (310) a set of features which describe characteristics of a place in an indoor space. This obtained set of features may describe characteristics of a place at which a wireless device is located, a place targeted by a wireless device as a destination, or a place targeted by a wireless device to avoid. Regardless, the method (300) further comprises comparing (320) the obtained set of features to addresses of respective indoor blocks into which the indoor space is spatially divided. Each indoor block in this regard is identified as being located at an address formed from a set of features which describe characteristics of the indoor block. The method (300) also comprises determining (330), based on the comparing, which of the indoor blocks corresponds to the place in the indoor space.

Abstract: An apparatus and methods for efficiently allocating channel state information (CSI) resources in a wireless communication system are provided. The apparatus includes a processing node configured to receive one or more channel features, wherein the one or more channel features are associated with a radio channel corresponding to a radio link connecting an access node and a user equipment. The processing node is configured to determine one or more distinguishing channel conditions based on the received one or more channel features, determine a desired channel state information (CSI) resource configuration based on the one or more distinguishing channel conditions, and allocate the desired CSI resource configuration based on the desired CSI resource configuration, and adjust a current CSI resource configuration associated with the radio channel, based on the determined desired CSI resource configuration.

Abstract: The core inventive points of this patent are the verification of a purchasing activity for a crowdsourcing based system and/or platform. There are two main aspects, the verification of purchasing certification from two sources and the verification of the implemented purchasing actions. The system respectively obtains the purchase proof from the implementing user and the purchase certification from the corresponding business owner. A comparison process is implemented to verify whether these two sources of purchase certification can be matched with each other. Furthermore, an address obtaining process is triggered when pre-defined user responses and/or actions were received to generate one or multiple obtained address associated with timestamp. And one or multiple extracted purchase addresses is obtained by respectively extract purchase address from the two sources of purchase certificate.

Abstract: A method for encrypting and verifying the integrity of a merchandise uses the merchandise detail information and its sequence to encrypt and verify the integrity of the merchandise. A sender selects the detail information and its sequence in advance as a key for the integrity encryption. After the merchandise is received, the receiver provides the corresponding detail information and its sequence according to the platform display and/or prompts. Further, the platform performs the comparison based on the corresponding two sets of detail information to determine whether the merchandise integrity verification is passed.

Abstract: Systems and methods for determining non-linear precoding coefficients are disclosed. In some embodiments, a method of determining non-linear precoding coefficients for transmitting at least one frequency tone on lines includes obtaining a channel matrix that relates an input of the lines to an output of the lines for the at least one frequency tone. The method also includes computing a metric for each line in a subset of the lines and determining a line order for the subset of the lines based on the metric for each line in the subset of the lines. The method also includes reordering elements of the channel matrix based on the line order for the subset of the lines to create a reordered channel matrix and determining the non-linear precoding coefficients based on the reordered channel matrix. This may provide a systematic way to sort lines and balance the bit rates between different lines.
