Abstract: Accordingly, the embodiment provides a method for detecting a beam failure event by a Base Station (BS) (100) in a wireless network (1000). The method includes transmitting at least one of a resource scheduling configuration and a reference signal configuration to at least one first User Equipment (UE) (300a) in the wireless network (1000). Further, the method includes determining whether at least one response is received from the first UE (300a). Further, the method includes detecting a beam failure event associated with at least one beam from the plurality of beams of the first UE (300a) in response to determining that the at least one response is not received from the first UE (300a).

Abstract: Precoding for multiple transmission streams in multiple antenna systems. Disclosed herein is a general method that transmits signal from multiple antennas using a one/two dimensional precoder. This precoder is fixed in a given resource block (RB) or slot, which is composed of P subcarriers and Q OFDM symbols (where the values for P and Q are greater than or equal to 1). The precoder in each resource block may take same or different values, which span the two dimensional time-frequency grid. The precoder is chosen as a function of either logical frequency index or physical frequency index of the RB.
