METHOD AND BASE STATION FOR CONTROLLING TRANSMISSION OF DATA STREAMS TO USER EQUIPMENTS IN A WIRELESS COMMUNICATION SYSTEM

摘要

Disclosed is a base station(130) configured to control transmission of data streams from the base station to a user equipment, UE, in a wireless communication system.The base station (130) provides transmission of at least three data streams.The base station further provides only two different hybrid automatic retransmission request, HARQ, downlink processes (703ab, 704ab). The base station comprises a mapping unit (702) for mapping Medium Access Control enhanced high speed, MAC-ehs, service data units, SDUs belonging to two different data streams of the at least three data streams to the same of the two different HARQ downlink processes. The MAC-ehs SDUs belonging to two different data streams are of equal size. Disclosed is also a corresponding method performed by a base station (130).
