full_form: Bandwidth Combination Set
context: First we look at interference from an aggressor UE in the ESMR band 817-824/862-869 MHz (the available extension of Band 5 in the United States) a victim Public Safety device or control station below 816 MHz (use of the Expansion Band) with regard to the applicable FCC emission limits on 90.691, described in Clause 5.3.2.1. The resolution bandwidth is not defined in the FCC rules but we follow the RSS-119 (and the historical) which defines the measurement bandwidth as 300 Hz at frequency offset less than 37.5 kHz from channel edge and 100 kHz for frequency offsets greater than 37.5 kHz. Results for 1 MHz resolution bandwidth is also given for the latter case. The emission limits that would apply are -20 dBm/0.3kHz at an offset between 12.5 kHz and 37.5 kHz from the ESMR block, and -13 dBm/100kHz beyond 37.5 kHz. For the UE unwanted emission results we assume a transmitter that just meets the LO leakage and IQ image minimum requirements for Rel-8, and with a counter-IM3 at -60 dBc (full
description: The Bandwidth Combination Set (BCS) defines supported bandwidth combinations for inter-band EN-DC (End-to-End Dual Connectivity), encompassing both LTE CA (Carrier Aggregation) and NR CA (New Radio Carrier Aggregation). It is specified in TS 36.101 for LTE CA and TS 38.101-1 for NR CA, as referenced in TS 38.101-3.
explanation: The text describes BCS as a set of defined bandwidth combinations used for inter-band EN-DC. It is further specified in technical standards (TS 36.101, TS 38.101-1, TS 38.101-3), indicating its role as a configurable parameter within the telecommunications network.
