Abstract: This disclosure describes techniques to facilitate a co-existence of overlapping spectrums within a base station node of a telecommunications network. More specifically, a spectrum sharing system is described that may employ static, semi-static, or dynamic techniques for spectrum re-framing of radio frames within a base station node. Spectrum re-framing may occur in a time domain, a frequency domain, or a combination of both. Further, the spectrum sharing system may determine the number of subframes of the first spectrum that are to be configured as MBSFN subframes based on the real-time network traffic and bandwidth allocation criteria. The bandwidth allocation criteria may include, but is not limited to, a regulatory requirement associated with a threshold bandwidth capacity for transmission of communications via a spectrum within the cell, or a service provider-imposed threshold bandwidth capacity on a cell that is intended to ensure a network efficiency of the base station node.

Abstract: Systems and methods for carrier sensing and symbol timing in a multiple-antenna communication system are provided. A wireless receiver receives two or more signals from two or more antennas, respectively. A set of column vectors comprising time samples obtained from each of the received signals at the two or more antennas are generated. A multiple-antenna eigen-combining (MAEC) vector is computed based on the set of column vectors. The respective received signals are multiplied with a corresponding combining coefficient of the MAEC vector to obtain a respective weighted signal. A combined signal is generated by adding the respective weighted signals and carrier sensing and symbol timing is performed on the two or more received signals based on the combined signal.
