name: DRS
full_form: Discovery Reference Signal
context: UE(s) to determine the frame timing and QCL assumptions from the detected SS/PBCH block. The feasibility and benefits of beam repetition for soft combining reception of SSBs within the same DRS transmission may be further considered. For SS/PBCH block transmissions as part of DRS, it is considered beneficial to expand the maximum number of candidate SS/PBCH block positions within the DRS transmission window to Y, for e.g., Y â¤ 64, where the choice of Y may depend on the numerology of the SS/PBCH blocks. The transmitted SS/PBCH blocks do not overlap and the maximum number of transmitted SS/PBCH blocks is X within DRS transmission window with X â¤ 8. The time-domain positions of the actually transmitted SS/PBCH blocks are selected from a set of Y candidate SS/PBCH block positions. Proposals for shift granularity between candidate time domain SSB positions/candidate groups of SSBs, duration of DRS transmission window, and duration of the transmitted DRS within the window including SSBs
description: Discovery Reference Signal (DRS) is a technology used in 5G networks to facilitate the discovery of base stations by user equipment. It involves the transmission of specific reference signals that enable the UE to determine the frame timing and Quality of Channel Link (QCL) assumptions.
explanation: The context describes DRS as a mechanism within 5G networks for base station discovery and frame synchronization, relying on specific signal transmissions. This clearly positions DRS as a technological element of 5G.
