Abstract: A network node in a wireless network executes a method of improving reliability in wireless communications. The method includes a step of deciding that a first network node is disconnected from the present link of a second network node, a step of allowing the first network to try to restore the present link, and a step of allowing the first network to establish a new link with the second network node according to one among switching rules arranged according to priority when the present link cannot be restored.

Abstract: A communications network includes a base station configured to wirelessly communicate first communication traffic with a first network entity using a first beam, and communicate second communication traffic with a second network entity using a second beam. Each of the first and second communication traffic includes backhaul traffic, wireless access traffic, and traffic for coordination between network entities.

Abstract: PURPOSE: An apparatus and a method for reference symbol transmission in an OFDM system are provided to reduce the duration of an OFDM symbol that carries reference symbols using a different and lower FFT/IFFT size than that used for data transmission. CONSTITUTION: A base station(200) includes a number of digital processing chains(205) called RF chains or digital chains. Each RF chain includes a respective baseband +RF processing block(210), a beamforming unit(215), and an antenna array(220). The base station includes a plurality of antenna arrays configured to transmit N spatial beams. Each baseband +RF processing block is coupled to the beamforming unit, which is further coupled to the antenna arrays. The number of spatial beams, N is greater than the number of RF processing chains. [Reference numerals] (210) Respective baseband +RF processing block; (215) Beamforming unit; (AA) N_RF RF chains; (BB) Antenna array; (CC) N beams
