Abstract
Official abstract text for this publication.
A method, an apparatus and a system for uplink rank adaptation are provided in the present invention, wherein the method comprises: estimating the maximum supportable data rate and channel information of a user equipment in uplink transmission; comparing the maximum supportable data rate with one or more predetermined thresholds, wherein the predetermined thresholds are associated with corresponding ranks; and determining a rank used by the user equipment in the uplink transmission based on a result of the comparison and the estimated channel information. With the present invention, a base station can quickly determine a rank for uplink MIMO transmission, decrease the rank estimating error, and lower the computation complexity for estimating the rank and the subsequent pre-coding vector.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for uplink rank adaptation, comprising: estimating a maximum supportable data rate and channel information of a user equipment in uplink transmission, wherein the maximum supportable data rate is estimated based on an estimation of uplink power headroom, transmit buffer status and an uplink transmission grant received from the user equipment; comparing the maximum supportable data rate with one or more predetermined thresholds, wherein the predete…
