full_form: Cell-specific Reference Signal
context: Cell 3, respectively. The CRS assistance information [7] is provided to the UE and includes information on Cell 2 and Cell 3. The purpose of the test is to verify the closed loop single-layer spatial multiplexing TM6 performance under assumption that UE applies CRS interference mitigation in the scenario with 2 CRS antenna ports in the serving and aggressor cells. Table 8.11.1.1.1.2-1: Test Parameters Table 8.11.1.1.1.2-2: Minimum performance for PDSCH 8.11.1.1.1.3 Minimum Requirement Single-Layer Spatial Multiplexing 4 Tx Antenna Port with CRS assistance information The requirements are specified in Table 8.11.1.1.1.3-2, with the addition of parameters in Table 8.11.1.1.1.3-1. In Table 8.11.1.1.1.3-1, Cell 1 is the serving cell, and Cell 2 and Cell 3 are the aggressor cells. The downlink physical channel setup is according to Annex C.3.2 for each of Cell 1, Cell 2 and Cell 3, respectively. The CRS assistance information [7] is provided to the UE and includes information on Cell 2 and
description: The Cell-specific Reference Signal (CRS) is a type of reference signal used in LTE downlink transmissions. It is cell-specific, meaning it is unique to each cell and is used by the user equipment (UE) for channel estimation and demodulation. The CRS assistance information provides details about the CRS configuration in neighboring cells, which helps the UE to mitigate interference from those cells.
explanation: The context mentions 'Cell-specific Reference Signal' as a signal used for channel estimation and demodulation, and also mentions 'CRS antenna ports' and 'CRS assistance information'. This indicates that CRS is related to the physical layer of the LTE downlink transmission, which falls under the category of Channel.
