Title:
USER EQUIPMENT UTILIZED IN MULTI-ANTENNA TRANSMISSION, AND METHOD AND DEVICE UTILIZED IN BASE STATION
Document Type and Number:
WIPO Patent Application WO/2018/099293
Kind Code:
A1
Abstract:
The invention discloses user equipment (UE) utilized in multi-antenna transmission, and a method and device utilized in a base station. The UE receives a first radio signal and then receives fist signaling. The first radio signal is transmitted via K antenna port sets. Each of the antenna port sets comprises a positive integer number of antenna ports. A first antenna port set is the first antenna port set in the K antenna port sets. The first signaling is used to determine a first timing resource pool. The first antenna port set is associated with at least one of {a first antenna virtualization vector, a second antenna virtualization vector}. The invention effectively reduces signaling overhead of dynamic scheduling of radio resources in a massive MIMO system.
