name: ABS
full_form: Almost Blank Subframes
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: Almost Blank Subframes (ABS) is a technique used in LTE networks to mitigate interference between cells. It involves almost blanking certain subframes in the aggressor cell to reduce interference on the victim cell's PDSCH transmission. The ABS pattern and parameters are specified in 3GPP standards, such as those mentioned in Tables 8.2.2.3.4-1 and 8.2.2.3.4-2, which define test parameters and minimum performance requirements for large delay CDD with 2 transmitter antennas under non-MBSFN ABS conditions.
explanation: ABS is classified as a Technology because it refers to a specific technique or method used in LTE networks to manage interference between cells, aligning with the 3GPP's specifications for efficient network operations.
