Webmore than 2 UCI bits, e.g., CSI report and more than 2 HARQ-ACK feedback bits. When PUCCH format 2 conveys relatively large payload, multiple PRBs (up to 16) can be allocated for the transmission of PF2. For PF2, after channel coding and QPSK modulation, the modulated UCI symbols are directly mapped on the allocated resource. WebIn LTE, link adaptation is carried out at the network side. However, as described in Chapter 9, the network typically bases the link-adaptation decisions on CSI reports provided by the devices.To enable coordinated link adaptation, that is, to allow for the network to take information about the transmission decisions made by neighboring transmissions into …
WebFeb 8, 2024 · Precoding assumes that channel state information (CSI) is known at the transmitter. Precoding starts with channel sounding that involves sending a coded message (called a sounding packet or a pilot signal) to the receiver. Each of the users send back their individual CSIs to the transmitter. The users’ CSIs are used to set the precoding ... WebCQI is Channel Quality Indicator. PMI stands for Pre-coding Matrix Indicator, and RI is Rank Indicator. These three values are computed on the fly in LTE systems and used to try to …
Web4.1.7 Relation between bandwidth part and carrier aggregation. CA is a bandwidth-extension technology supported since the LTE-Advanced era, which can aggregate multiple component carriers (CC) for simultaneous reception or transmission. According to the range of aggregated carriers, CA can be divided into intraband CA and interband CA.
