WebIndexTerms— Broadcastchannels, downlink,multipleantennas, wireless system. I. INTRODUCTION W E consider a memoryless vector Gaussian broadcast channel to model the downlink of a wireless system with antennas at the base station and users with a single antenna at each receiver. Focusing on one particular time WebJan 19, 2016 · PMP uses a shared broadcast channel in the downlink direction so that we don't send copies of packets and wasting airspace for repeated data. Without setting broadcast CIR, it is possible that broadcast traffic will struggle to get scheduled if there is constant normal data traffic. Also, the CIR isn't fully "reserved" in a strict sense ...

WebJan 5, 2024 · We formulate and analyze a fundamental downlink transmission scheduling problem in a wireless communication system, composed of a base station and a set of users, each requesting a packet to be served within a time window. Some packets are requested by several users and can be served simultaneously due to the broadcast … Web2 Downlink messages broadcast over 500 KHz channels can use all six available spreading factors (SF7…SF12). Table 1: LoRa Spreading Factors. Importantly, the LoRa modulation spreading factors are inherently orthogonal. This means that signals modulated with different spreading factors and transmitted on the same frequency channel at the …
