Rate-memory trade-off for the cache-aided MISO broadcast channel with hybrid CSIT

Massive MIMO makes the pathwise approach viable: the (cross-link) BF can be updated at a reduced (slow fading) rate, parsimonious channel representation facilitates not only uplink

Abstract—For the two-user MISO broadcast channel with im- perfect and delayed channel state information at the transmitter (CSIT), the work explores the tradeoff between

The two classical (nonregular) channel models that allow permanent perfect CSIT for Doppler rate perfect channel feedback are block fading and bandlimited (BL) stationary channels..

Further progress came with the work in [9] which, in addition to exploring the effects of the quality of current CSIT, also considered the effects of the quality of delayed CSIT,

Abstract—The degrees of freedom (DoF) of a K-User MISO broadcast channel (BC) is studied when the transmitter (TX) has access to a delayed channel estimate in addition to an

We generalize the concept of precoding over a multi-user MISO channel with delayed CSIT for arbitrary number of users case, by proposing a precoder construction algorithm,
