Joint Time and Power Allocation for 5G NR Unlicensed Systems

نویسندگان

چکیده

The fifth-generation (5G) and beyond networks are designed to efficiently utilize the spectrum resources meet various quality of service (QoS) requirements. unlicensed frequency bands used by WiFi mainly deployed for indoor applications not always fully occupied. cellular industry has been working enable coexistence. In particular, 5G New Radio in channel (NR-U) supports uplink downlink transmission on maximum occupation time (MCOT) duration. this paper, we consider maximizing total throughput both NR-U jointly optimizing power allocation during MCOT while ensuring fair coexistence with WiFi. Fairness is guaranteed two steps: 1) tuning access related parameters achieve proportional fairness, 2) including 3GPP fairness from perspective as a constraint maximization. Numerical analysis simulation have demonstrated superior performance proposed resource algorithm compared conventional deployment strategies.

A Hybrid Game Approach for Joint User Selection and Power Allocation over Unlicensed Spectrum Bands

This paper studies sharing of unlicensed spectrum bands between network operators by formulating it as a hybrid noncooperative game. A multi-user multi-channel downlink transmission is considered where the communication links are modeled as Gaussian parallel interference channels. Each transmitter, controlled by a competing operator, selects one user per channel from its registered users as wel...

Joint Power Allocation and Beamforming for Non-Orthogonal Multiple Access (NOMA) in 5G Millimeter-Wave Communications

In this paper we explore non-orthogonal multiple access (NOMA) in millimeter-wave (mmWave) communications (mmWave-NOMA). In particular, we consider a typical problem, i.e., maximization of the sum rate of a 2-user mmWave-NOMA system. In this problem, we need to find the beamforming vector to steer towards the two users simultaneously subject to an analog beamforming structure, while allocating ...

Joint Power Allocation and Constellation Design for Cognitive Radio Systems

Cognitive radio is a smart software-defined radio that can adapt its transmission parameters, such as transmit power level and modulation type, based on the wireless channel conditions. In this paper, we introduce a joint power allocation and constellation design algorithm for cognitive radios assuming spectrum sensing imperfections. The proposed algorithm minimizes the symbol error rate of the...

Energy efficient power allocation strategy for 5G carrier aggregation scenario

Carrier aggregation (CA) is considered to be a potential technology in next generation wireless communications. While boosting system throughput, CA has also put forward challenges to the resource allocation problems. In this paper, we firstly construct the energy efficiency optimization problem and prove that the function is strictly quasi concave. Then we propose a binary search-based power a...

Worst-Case Robust Distributed Power Allocation in Shared Unlicensed Spectrum

This paper considers non-cooperative and fully-distributed power-allocation for selfish transmitterreceiver pairs in shared unlicensed spectrum when normalized-interference to each receiver is uncertain. We model each uncertain parameter by the sum of its nominal (estimated) value and a bounded additive error in a convex set, and show that the allocated power always converges to its equilibrium...
