name: SFBC
full_form: Space Frequency Block Coding
context: The requirements are specified in Table 8.2.2.2.7-2, with the addition of parameters in Table 8.2.2.2.7-1 and the downlink physical channel setup according to Annex C.3.2. The purpose is to verify the performance of transmit diversity (SFBC) with 2 transmit antennas when the PDSCH transmission in the serving cell is interfered by PDSCH of two interfering cells applying transmission mode 9 interference model defined in clause B.6.4. In Table 8.2.2.2.7-1, Cell 1 is the serving cell, and Cell 2, 3 are interfering cells. The downlink physical channel setup is according to Annex C.3.2 for each of Cell 1, Cell 2 and Cell 3, respectively.

description: Space Frequency Block Coding (SFBC) is a technique used in wireless communication systems to improve the reliability of data transmission. It involves coding data across both space and frequency domains, allowing for better resistance to fading and interference. In the context of 3GPP specifications, SFBC is particularly relevant for transmit diversity schemes, where multiple antennas are used at the transmitter side to enhance signal quality and robustness against interference.
explanation: SFBC is classified under Technology because it refers to a specific method or technique employed in telecommunications systems to achieve improved performance. The provided context highlights its application in transmit diversity scenarios with multiple antennas, aligning with the broader category of technologies used within 3GPP specifications for enhancing communication efficiency and reliability.
