Thanks for the good explanation. There i...Hi Askok,<br />Thanks for the good explanation. There is an error in describing how RSSI is calculated according to 3GPP specs.<br /><br />Regarding RSSI, this is what 36.214 says:<br /><br />E-UTRA Carrier Received Signal Strength Indicator (RSSI), comprises the linear average of the total received power (in [W]) observed only in OFDM symbols containing reference symbols for antenna port 0, in the measurement bandwidth, over N number of resource blocks by the UE from all sources, including co-channel serving and non-serving cells, adjacent channel interference, thermal noise etc. <br /><br />Hence RSSI is only measured in the carriers (resource-elements) where the reference symbol is contained, and not over the entire spectrum.<br /><br />Regards<br />IrfanAnonymoushttps://www.blogger.com/profile/07461236987161577184noreply@blogger.comtag:blogger.com,1999:blog-5521156586035954084.post-26441563968691122452013-10-11T06:04:38.771-07:002013-10-11T06:04:38.771-07:00now a days technology improves wireless technology...now a days technology improves wireless technology better<br /><a href="%E2%80%9D" rel="nofollow">av consultant</a>Anonymoushttps://www.blogger.com/profile/17152901122419197715noreply@blogger.comtag:blogger.com,1999:blog-5521156586035954084.post-10109286422767968702013-08-30T00:28:42.214-07:002013-08-30T00:28:42.214-07:00Hi Rajesh,

Thanks for sharing this information.
I...Hi Ashok,<br /><br />Thanks for sharing this information.<br /><br />Is RSRP calculated by taking linear average of all the reference signals present in the OFDMA symbol or it is measured in single RE that carrier the reference signals.<br /><br />-RBRBhttps://www.blogger.com/profile/17887331338613217778noreply@blogger.com
