Robust Downlink Multi-Antenna Beamforming With Heterogenous CSI: Enabling eMBB and URLLC Coexistence

Abstract: Two of the main problems to achieve ultra-reliable low-latency communications (URLLC) are related to instantaneous channel state information (I-CSI) acquisition and the coexistence with other service modes such as enhanced mobile broadband (eMBB). The former comes from the non-negligible time required for accurate I-CSI acquisition, while the latter, from the heterogeneous and conflicting requirements of different nodes sharing the same network resources. In this paper, we leverage the I-CSI of multiple eMBB l… Show more

“…In recent years, several works have focused on the solution to minimum-power precoding design problems where the UEs have strict QoS requirements, e.g., SINR, outage probability, data rate [12]- [19]. For instance, the work in [13] proposed a worst-case MIMO precoding design to guarantee an SINR performance of the UE for every channel realization and channel estimation error, thus, robust against channel/estimation uncertainties.…”

“…In [37], the authors proposed a spectrum partition scheme for maximizing the eMBB data rate and satisfying the URLLC latency and reliability. In [38], the authors proposed a precoding design in order to minimize the transmit power of a Base Station (BS) while satisfying the QoS of eMBB and URLLC users based on imperfect CSI. Joint Transmission (JT) and Orthogonal Transmission (OT) modes were investigated for satisfying the Block Error Rate (BLER) and data rate of URLLC and eMBB, respectively in [39].…”

“…Precoding [79]): Assume that a critical data message arriving at the data queue of a multiantenna node A demands an urgent URLLC transmission to a single-antenna node B. Because of the stringent latency constraints, the transmission needs to be carried out immediately in one shot; thus, instantaneous CSI cannot be acquired at A.…”

“…Alternatively, and/or in addition, one might leverage a probabilistic upper bound of the sample mean to ensure ( 28) is met with a certain confidence level. Such bound can be designed exploiting the central limit theorem, as in [79]. In general, the confidence intervals narrow as L increases.…”
