Coexistence of MIMO Radar and FD MIMO Cellular Systems With QoS Considerations

Abstract: In this work, the feasibility of spectrum sharing between a multiple-input multiple-output (MIMO) radar system (RS) and a MIMO cellular system (CS), comprising of a full duplex (FD) base station (BS) serving multiple downlink and uplink users at the same time and frequency is investigated. While a joint transceiver design technique at the CS's BS and users is proposed to maximise the probability of detection (PoD) of the MIMO RS, subject to constraints of quality of service (QoS) of users and transmit power at… Show more

“…3. Next, we quantify the performance of the CS (operating in the spectrum shared by the RS) in terms of area throughput 16 (Mbps/m 2 ). However, prior to that, in order to verify that Phase 3 of Algorithm 1 does not violate the interference temperature set by the RS in Phase 1, we show the complementary cumulative distribution (CCD) of the total interference power from the CS to RS, i.e., P[I RAD ≤ Γ].…”

“…In particular, we consider a system wherein the CS seeks to improve the users' QoS on the best-effort basis, while ensuring a guaranteed detection probability at the RS. This is in contrast to prior works, e.g., [16], [17], where the interference towards the RS is controlled on the best-effort basis, but subject to the hard requirements on the QoS at the CS. Please note that the interference from the CS towards the RS is of utmost concern owing to the level of seriousness involved in the RS's operation.…”

“…Full duplex (FD) [1]- [4] and non-orthogonal multiple access (NoMA) [5]- [10] have emerged as promising technologies to provide higher spectrum efficiency (SE) in 5G and beyond wireless communications systems. In particular, FD communications allows the radios to simultaneously transmit and receive on the same frequency channel, potentially doubling the SE [11]- [14]. Similarly, for the case of NoMA, unlike conventional orthogonal multiple access (OMA), multiple users are served on the same timefrequency resources by exploiting power domain multiplexing to improve the system's SE and achieve higher cell-edge throughput, and low transmission latency [15]- [17].…”

“…Related Work: Multi-antenna techniques have been wellexplored in the radar-communications coexistence literature. In the case of coordination between the primary and secondary users, MIMO techniques have been investigated in the context of spectrum sharing between a MIMO radar and the MU-MIMO downlink [2], MIMO radar and full-duplex cellular systems [3], and MIMO radar and a MIMO communication system [4], under performance and power constraints. Even though secondary user interference mitigation is possible using multi-antenna radars in uncoordinated scenarios [5], its feasibility in the presence of a large multi-cell network of massive MIMO BSs is limited to scenarios of sparse deployments and/or large exclusion zone radii.…”

“…As we will discuss in Appendix A, Assumption 2 does not impact the worst-case analysis 3. The FDR is dependent on the radar receiver architecture, spectrum of the interfering signal, and is independent of other parameters.…”
