1. A method for assigning a sounding resource by an Access Point (AP) in a Time Division Duplex (TDD) cellular network, the method comprising:
- obtaining channel information between a serving AP and a User Equipment (UE) served by the serving AP;
determining whether to assign the sounding resource to the UE according to a predetermined assigning criteria and based on the channel information, wherein the channel information comprises at least one of path gain information and Uplink/Downlink (UL/DL) channel quality information, and wherein the predetermined assigning criteria prioritize UEs having smaller path-loss and/or suffering/generating less UL/DL inter-cell interference;
making the sounding resource assignment if it is determined to assign the sounding resource to the UE.

Abstract
The embodiments disclose a method and an Access Point (AP) for assigning a sounding resource in a Time Division Duplex (TDD) cellular network. The method obtains a channel information between a serving AP and a User Equipment (UE) served by the serving AP, determines whether to assign the sounding resource to the UE according to the predetermined assigning criteria based on the channel information, and makes the sounding resource assignment if it is determined to assign the sounding resource to the UE.

19. A computer program product stored in a non-transitory computer readable medium for assigning a sounding resource by an Access Point (AP) in a Time Division Duplex (TDD) cellular network, the computer program product comprising software instructions which, when run on one or more processing circuits, causes the one or more processing circuits to:
-
obtain channel information between a serving AP and a User Equipment (UE) served by the serving AP; determine whether to assign the sounding resource to the UE according to a predetermined assigning criteria and based on the channel information, wherein the channel information comprises at least one of path gain information and Uplink/Downlink (UL/DL) channel quality information, and wherein the predetermined assigning criteria prioritize UEs having smaller path-loss and/or suffering/generating less UL/DL inter-cell interference; make the sounding resource assignment if it is determined to assign the sounding resource to the UE.
