carrier aggregation

Samsung Electronics and MediaTek achieved a peak throughput rate of 363Mb/s in a test of standalone 5G uplink two-carrier aggregation (2CA) using three transmit antennas to improve upload efficiency.

T-Mobile US claimed it recorded the fastest uplink data rates in the US using two-channel carrier aggregation (2CA) on its standalone (SA) 5G network, throwing a gauntlet down to rival AT&T, which detailed its own work on the approach…

Ericsson and MediaTek laid claim to having achieved a 5G downlink speed record for carrier aggregation (CA) comprising one FDD and three TDD channels, a combination promoted by the Swedish vendor as increasing 5G deployment options.

BT hailed progress with its move towards commercial standalone (SA) 5G after completing a carrier aggregation (CA) trial combining four spectrum channels on mobile operator EE’s live network in collaboration with network partner Nokia.

NTT Docomo and Qualcomm claimed a global first after activating carrier aggregation (CA) on the operator’s 5G network using two sub-6GHz spectrum bands, delivering peak downloads speeds of 4. 2Gb/s on Snapdragon 865-equipped devices.

Qualcomm and Ericsson trialled a standalone 5G implementation of carrier aggregation between TDD and FDD bands, in a showcase of a technology deemed critical to expansion of next generation networks.

Optus claimed a world-first after conducting a non-standalone (NSA) 5G call using carrier aggregation of the 2300MHz and 3500MHz bands, a move it predicted would bring it closer to boosting its network capabilities.
