Abstract: The present disclosure belongs to the technical field of intelligent kin recognition, and relates to a new biological kin recognition method and system based on unsupervised clustering of mRNA bases, including the following steps: step S1, extracting base codons from an mRNA chain, and re-encoding the base codons according to encoding rules; step S2, converting a re-encoded base chain into a document capable of being identified by a model; step S3, inputting the document into the model to vectorize base texts, and clustering vectorized base texts; and step S4, visualizing clustering results to obtain a biological kin recognition result. The present disclosure does not need to artificially annotate the data, saves labor costs, and avoids effects of artificial factors on taxonomical results, featuring simple use, efficient program run, and fast speed.

Abstract: A method and a radio base station are provided for selecting a first User Equipment (UE) and at least a second UE from a plurality of UEs, for sharing a transmission resource in the time-frequency dimension in a multiple input multiple output (MIMO) transmission. A first and second imperfection of Channel State Information (CSI) made available for the first UE and second UE, respectively is estimated (410, 420). Spatial correlation between the first UE and the at least second UE is estimated (450), and the first and at least second UE are selected (470) to share a transmission resource in the time-frequency dimension, if both of the first and second imperfections are determined above (430, 440) a first threshold and the spatial correlation is determined below (460) a second threshold.

Abstract: The present invention proposes a method, a radio base station and a wireless communication system for optimizing Inter-cell Interference Coordination, wherein a user equipment is communicated within a cell served by the radio base station, comprising: obtaining one or more channel conditions on the communication channel between the user equipment and the radio base station, establishing a utility function as a function of Signal to Interference-and-Noise Ratios SINRs to model the user equipment's satisfaction level in terms of quality of service and power consumption based on the obtained channel conditions, selecting a SINR that enables to maximize the value of the utility function as a target SINR, and determining a transmit power to be used by the user equipment as a function of the target SINR. Thus, a self-optimized inter-cell interference coordination (ICIC) without X2 signaling between base stations is achieved and greedy power allocation is avoid.

Abstract: A cross-layer multi-packet reception media access control and resource allocation technique is provided for wireless networks having receivers with multiple antennas. User devices on the wireless network access the network for data transmission by making a request to send (RTS) request after a random backoff time. In response to a request to send, an access point (or other receiver) determines transmission parameters that optimize the use of the physical layer based at least in part on channel state information. Those transmission parameters are transmitted along with a clear to send (CTS) message from the receiver to an indicated transmitter. Once the CTS message is received, data is transmitted in accordance with transmission parameters.

Abstract: Various embodiments of the disclosed subject matter provide cross layer medium access control systems and methods that dynamically adjusts each node's transmission probability according to physical layer characteristics. Accordingly, when a backoff time counter reduces to zero, each node can selectively transmit according to network population, current CSI, and MPR capability of the system. The disclosed details enable various refinements and modifications according to system design considerations.
