MIMO) the Resource elements allocated to reference signals on one antenna are DTX on the other antennas

In case more than one antenna is used (e.g.

Reference signals position in time domain is fixed (0 and 4 for Type 1 Frame) whereas in frequency domain it depends on the Cell ID.

Channel estimation in LTE is based on reference signals (like CPICH functionality in WCDMA).

So at any point in time the UE will measure all the REs that carry the RS and average the measurements to obtain an RSRP reading. This mapping follows a specific pattern (see to below). In simple terms the Reference Signal (RS) is mapped to Resource Elements (RE). 5 FuramaxclusiVe Villas & spa ubuD bali inDonesia 174 56 5 - DOKUMEN.TIPS The 24 Best Free Movies On YouTube Right Now Funding Manager Resume Samples | QwikResume Reference Signals recap: OFDMA Channel Estimation 5 banYan tree unGasan bali bali inDonesia 170 23 5.

If the UE can reliably detect that R1 is available it may use R1 in addition to R0 to determineRSRP. Reference Signal Received Power (RSRP), is defined as the linear average over the powercontributions (in ) of the resource elements that carry cell-specific reference signals within theconsidered measurement frequency bandwidth.įor RSRP determination the cell-specific reference signals R0 according TS 36.211 shall beused.

Wideband N = full bandwidth (up to 100 Resource Blocks / 20 MHz).

Narrowband N = 62 Sub Carriers (6 Resource Blocks).

It must to bemeasured over the same bandwidth: In the procedure of handover, the LTE specification provides the flexibility of using RSRP, RSRQ, or both. RSRQ –Reference Signal Received Quality:Quality considering also RSSI and the number of used Resource Blocks (N) RSRQ = (N * RSRP) / RSSI measured over the same bandwidth.RSRQ is a C/I type of measurement and it indicates the quality of the received reference signal.The RSRQ measurement provides additional information when RSRP is not sufficient to make a reliable handover or cell reselection decision.

It is the power of the LTE Reference Signals spread over the full bandwidth and narrowband.Ī minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ RSRP –Reference Signal Received Power:RSRP is a RSSI type of measurement, as follows there are some definition of it and some details as well.
