On Optimal Scheduling for Joint Spatial Division and Multiplexing Approach in FDD Massive MIMO
Massive MIMO is widely considered as a key enabler of the next generation 5G networks. With alarge number of antennas at the Base Station, both spectral and energy efficiencies can be enhanced.Unfortunately, the downlink channel estimation overhead scales linearly with the number of antennas.This burden is easily mitigated in TDD systems by the use of the channel reciprocity propert...
متن کاملSpatial Modulation- Spatial Multiplexing in Massive MIMO
Massive MIMO, a candidate for 5G technology, promises significant gains in wireless data rates and link reliability by using large numbers of antennas (more than 64) at the base transceiver station (BTS). Extra antennas help by focusing the transmission and reception of signal energy into eversmaller regions of space. This brings huge improvements in throughput. However, it requires a large num...
متن کاملJoint Spatial Division and Multiplexing
We propose Joint Spatial Division and Multiplexing (JSDM), an approach to multiuser MIMO downlink that exploits the structure of the correlation of the channel vectors in order to allow for a large number of antennas at the base station while requiring reduced-dimensional Channel State Information at the Transmitter (CSIT). This allows for significant savings both in the downlink training and i...
متن کاملGraph Theory Based Approach to Users Grouping and Downlink Scheduling in FDD Massive MIMO
Massive MIMO is considered as one of the key enablers of the next generation 5G networks. With a high number of antennas at the BS, both spectral and energy efficiencies can be improved. Unfortunately, the downlink channel estimation overhead scales linearly with the number of antenna. This does not create complications in Time Division Duplex (TDD) systems since the channel estimate of the upl...
متن کاملJoint spatial division and multiplexing - Benefits of antenna correlation in multi-user MIMO
We show that the sum capacity of “spatially wellcorrelated” Gaussian MIMO broadcast channel (BC) is rather larger than that of the uncorrelated (i.i.d. Rayleigh fading) Gaussian MIMO BC, assuming a special structure of transmit correlation of users. Moreover, a potential sum-rate gap of an ideal correlated Rayleigh fading channel is shown to be M logM over the uncorrelated case, where M is the ...
