Downlink frame structure
WebThe frame structure below (Figure 1) is applicable to TDD.Each radio frame of length T f = 307200*T s = 10 ms consists of two half-frames of length T f = 153600*T s = 5 ms each. Each half-frame consists of five subframes of length 307200*T s = 1 ms.The supported uplink-downlink configurations are listed in Table 2 where, for each subframe in a radio … WebSection 3 describes in detail the flexible frame structure and the effect of scalable numerology on the MAC layer. ... The control channel can be multiplexed with other downlink PHY channels and mapped contiguously or non-contiguously in the frequency domain. This highly adaptable architecture can minimize downlink control channel …

WebFigure 9.3: Downlink frame structure. The cell-specific reference signals are carried in all downlink subframes. The downlink unicast transmissions can be configured to use one, two or four antenna ports. The reference … WebThe downlink and uplink frame structure parameters are the same, except that the time-domain underlying symbols in the downlink are OFDM symbols, whereas in the uplink the underlying symbols are SC-FDMA symbols due to the use of different multiple access methods in the uplink and downlink. In this chapter, some of the uplink-specific aspects …
WebNR does just as LTE make use of the Primary Synchronization Signal and Secondary Synchronization Signal for physical cell ID acquisition and synchronization to the downlink frame structure of a cell. The NR PBCH carries the master information block which contains the most critical system information such as system frame number, system ... WebSep 21, 2010 · 6.3.1 Frame Structure. Before going into details about the resource block structure for the downlink, we first describe the frame structure in the time domain, which is a common element shared by both downlink and uplink. In LTE specifications, the size of elements in the time domain is expressed as a number of time units T s = 1/(15000 x …
WebGPON Downlink Frame Structure. Each GTC (GPON Transmission Convergence) frame consists of PCBd (Physical Control Block downstream) and payload. Downlink frame’s fixed 125us frequency is 8000Hz, and its’ size is 38,880 bytes, when speed rate reaching 2.488Gbps. GTC payload definitely is the “payload” of GEM Frame in downstream.
