Title:
METHOD AND APPARATUS FOR LINK ADAPTATION IN A MIXED TRAFFIC ENVIRONMENT
Document Type and Number:
WIPO Patent Application WO/2019/010697
Kind Code:
A1
Abstract:
The present disclosure is to provide some solutions for link adaptation to cope with a mixed traffic environment. The present disclosure provides a method for performing link adaptation at a network node in a wireless communication network, which may comprise identifying first traffic and second traffic included in transmission between the network node and a user equipment (UE), wherein the first traffic is related to first service having a first quality of service (QoS) requirement, and the second traffic is related to second service having a second QoS requirement; and applying a first link adaptation loop catering for the first QoS requirement to the first traffic, and applying a second link adaptation loop catering for the second QoS requirement to the second traffic. In one example, the second link adaptation loop is independent from the first link adaptation loop. In another example, the second link adaptation loop is dependent on the first link adaptation loop. The solutions can concurrently meet the different requirements of different services in the mixed traffic environment.
