METHOD AND ARRANGEMENTS FOR SUPPORTING SERVING OF MULTIPLE WIRELESS DEVICES BASED ON PREDICTION OF RADIO CHANNEL ESTIMATION ACCURACY DEGRADATION

Document Type and Number:

WIPO Patent Application WO/2023/115398

Kind Code:

A1

Abstract:

Methods and arrangements (110; 100; 130; 200; 201; 800; 803) for supporting serving of multiple wireless devices (120a-c) by a radio network node (110) of a wireless communication network (100). It is obtained (502-505; 603-606; 701) channel estimation accuracy degradation information for at least one of the multiple wireless devices (120a-c), wherein said channel estimation accuracy degradation information for respective one of said at least one wireless devices (120a-c) indicates a prediction of a degradation of radio channel estimation accuracy for this wireless device (120a) during TDD downlink slots (4). Said multiple wireless devices (120a-c) are being scheduled in said TDD downlink slots (4) based on the obtained channel estimation accuracy degradation information, such that the greater the predicted degradation of radio channel estimation accuracy is for a wireless device (120a) among said wireless devices (120a-c), the greater influence is applied for scheduling the wireless device (120a) early among said TDD downlink slots (4).
