WebThe basic principles for non-codebook-based precoding can be explained based on Figure 6.19 (where the precoder is intentionally shaded; see later). As can be seen, this figure is very similar to the corresponding figure illustrating codebook-based precoding (Figure 6.17), with layer mapping of modulation symbols corresponding to one or two transport blocks … WebThis example shows steps 1 to 6 for two separate cases for the PUSCH, with one resource block occupying all of the OFDM symbols in a slot, a single layer, a pi/2-BPSK modulation scheme, and DM-RS symbols occupying OFDM symbols 2, 7, and 11 (0-based).
First, an introduction to some of the terms used in describing an LTE Frame. There are six time units: frame, half-frame, subframe, slot, symbol, and the basic time unit (Ts), as shown in the following table. Below is an illustration of an FDD frame. A resource block (RBResource Block) is the smallest unit of … See more The bandwidths defined by the standard are 1.4, 3, 5, 10, 15, and 20 MHz. The table below shows how many subcarriers and resource blocks there … See more In FDD mode, uplink and downlink frames are both 10ms long and are separated either in frequency or in time. For full-duplex FDD, uplink and downlink frames are separated by frequency and are transmitted … See more Uplink user transmissions consist of uplink user data (PUSCH), random-access requests (PRACH), user control channels (PUCCH), and … See more In TDD mode, the uplink and downlink subframes are transmitted on the same frequency and are multiplexed in the time domain.

The main aim of UL PC is to reduce interference and to reduce UE power consumption. Interference can be intracell interference or intercell interference. There are 2 power control schemes : conventional PC schemes and fractional PC schemes.
