Abstract: The present disclosure describes the concept of operations and the medium access control protocols of a wireless communication system using code-division multiple access with interference avoidance (CDMA-IA) as its physical layer. The system can dynamically share a common band with other networks without a central radio resource controller. In one embodiment, the wireless communication system includes a plurality of radio nodes forming a wireless mesh network, wherein the pairs of radio nodes use, individually optimized, time division duplexing. At least one radio node includes a software-defined radio, a memory, and an electronic processor. The electronic processor is configured to control the software-defined radio to transmit a pilot signal and share various state information with the other nodes of the network. The shared information includes local spectrum occupancy and node connectivity sets. The pervasive sharing of spectrum occupancy among all nodes enables the usage of the shared band to be maximized.

Abstract: The present disclosure relates to a method for controlling communication compensation, comprising: determining a length class of a communication link according to a time length of pulse data transmitted on the communication link; and determining a compensation scheme for communication compensation according to the length class of the communication link. In the invention, a length class of a communication link determined according to a time length of pulse data transmitted on the communication link is used to determine a compensation scheme for communication compensation so as to perform time compensation on data, thereby preventing attenuation caused by an excessively long communication distance, and improving the stability of long-distance communication performed by means of Homebus. Also disclosed are an apparatus for controlling communication compensation, and an air conditioner.

Abstract: A method for transmitting a channel status information reference signals (CSI-RSs) for a maximum of eight antenna ports includes mapping the CSI-RSs for a maximum of eight antenna ports onto a data region of a downlink subframe having a normal cyclic prefix (CP) configuration according to a predetermined pattern; and transmitting the downlink subframe to which the CSI-RSs mapped, wherein the predetermined pattern defines the CSI-RSs to be mapped onto two OFDM symbols of the data region in the downlink subframe and mapped to at least one of four subcarrier positions in each of the two OFDM symbols, and wherein the four subcarrier positions defined by the predetermined pattern may be two consecutive subcarrier positions and two other consecutive subcarrier positions spaced apart by four subcarriers.

Abstract: A relay station configured to orbit a celestial body and configured to receive data from a population of devices arranged at the celestial body, the relay station and the devices configured to travel with respect to one another. The relay station includes a receiver configured to receive signals from the devices, the signals including a signal that is part of the signals, the signal including signal data in data packages that are at least part of the data. The relay station also includes a signal-processing device configured to receive the signal from the receiver and extract the signal data from the signal. The signal-processing device is configured to correct the signal for a positive Doppler shift or a negative Doppler shift. The relay station also includes a transmitter configured to transmit the signal data from the signal processing device to a server arranged remotely from the relay station at the celestial body.

Abstract: In 5G Non-Standalone (NSA), to balance the load on 5G users and 4G users effectively, the disclosed technology selects the proper secondary cell group (SCG), when the master cell group (MCG) is provided by 4G infrastructure. E-UTRAN New Radio-Dual Connectivity (ENDC) allows users to connect to a 4G MCG and a 5G SCG (SCG). The technology selects the SCG based on each user's application's attributes such as UL/DL data volume, speed or bandwidth.

Abstract: A method for compensating group delay variations in a CDMA spread spectrum receiver, comprising: receiving an RF signal; generating an ideal replica signal; filtering the RF signal by one or more filters; obtaining an ideal auto-correlation function (ACF) of the ideal replica signal; distorting the ideal ACF to generate a distorted ACF by a filtering model of the one or more filters; aligning the ideal ACF and the distorted ACF; calculating a set of correction factors based on a ratio of the ideal ACF and the distorted ACF; calculating a cross-correlation signal based on the filtered RF signal and the ideal replica signal; and obtaining a compensated correlation signal by applying the set of correction factors to the cross-correlation signal.
