TL;DR: In this article, the uplink access configuration index is used to identify an uplink AP from among a predetermined plurality of AP configurations, and then the AP is transmitted to the wireless communications network according to the identified AP.

TL;DR: In this article, a method of antenna array dynamic configuration for 3D beamforming in wireless network is provided, comprising of determining dynamically a mapping pattern for transforming a physical antenna array into a virtual antenna array based on time-varying downlink or uplink baseband channel statistics, from a set of candidate mapping patterns.

TL;DR: In this article, a first radio network node (110) and a method therein for measuring interference as well as a second radio node (120) and an approach for enabling the first radio node to measure interference are disclosed.

TL;DR: In this article, the authors propose a method and a base station (110 ) for interference management in a cellular network employing Space-Division uplink (UL) downlink (DL) duplexing (SDD) in which the base station assigns a plurality of Remote Radio Units (RRUs) as Tx RRUs operable to dedicatedly transmit downlink signals to the UEs and Rx RRUs operating to receive uplink signals from the plurality of UEs at the same frequency band and same time as the transmission of the RRUs.

TL;DR: In this paper, the synchronizing frequency among a cluster of coordinated transmission points cooperating in a coherent joint transmission is discussed, where one transmission point is set (510) as a reference transmission point for a group of coordinated transmit points.
