name: CDD
full_form: Cyclic Delay Diversity
context: The requirements for non-MBSFN ABS are specified in Table 8.2.2.3.4-2, with the addition of parameters in Table 8.2.2.3.4-1. The purpose is to verify the performance of large delay CDD with 2 transmitter antennas if the PDSCH transmission in the serving cell takes place in subframes that overlap with ABS [9] of the aggressor cell with CRS assistance information. In Table 8.2.2.3.4-1, Cell 1 is the serving cell, and Cell 2 and Cell3 are the aggressor cells. The downlink physical channel setup for Cell 1 is according to Annex C.3.2 and for Cell 2 and Cell 3 is according to Annex C.3.3, respectively. The CRS assistance information [7] includes Cell 2 and Cell 3.

description: Cyclic Delay Diversity (CDD) is a transmission technique used in the Evolved Universal Terrestrial Radio Access Network (E-UTRA) to improve the performance of downlink transmissions. It involves introducing cyclic delays between different transmitter antennas to enhance signal diversity and mitigate interference. In the context of non-MBSFN ABS, CDD with large delay is tested for its performance when PDSCH transmission in the serving cell overlaps with ABS of aggressor cells having CRS assistance information.
explanation: CDD is classified as a Technology because it refers to a specific transmission technique used in E-UTRA to enhance signal diversity and mitigate interference. The provided context from 3GPP TS 36.101 highlights its application in non-MBSFN ABS scenarios, demonstrating its role in improving downlink transmission performance.
