Methods and Apparatus for Multiple Connectivity in a TDD System

A method implemented in a wireless communication system comprising points that have time division duplex, TDD, configurations, wherein the method comprises:

• obtaining information indicating the TDD configuration of each of multiple points to which a particular wireless communication device is simultaneously connected, the particular device being incapable of simultaneous uplink and downlink communication;
• determining, based on the obtained information, that one or more time-domain radio resources used by the multiple points are conflicting resources defined by the TDD configuration of one or more of the multiple points as being uplink resources and defined by the TDD configuration of one or more others of the multiple points as being downlink resources;
• and
• resolving, for the particular device, each of the one or more conflicting resources as either an uplink resource to be used by the device, a downlink resource to be used by the device, or a resource not to be used by the device, based on one or more rules for optimizing use of conflicting resources.

An apparatus in a wireless communication system comprising points that have time division duplex, TDD, configurations, the apparatus comprising:

• one or more communication interfaces configured to communicatively connect the apparatus to a system;
• and
• one or more processing circuits configured to:
• obtain information indicating the TDD configuration of each of multiple points to which a particular wireless communication device is simultaneously connected, the particular device being incapable of simultaneous uplink and downlink communication;
• and
• determine, based on the obtained information, that one or more time-domain radio resources used by the multiple points are conflicting resources defined by the TDD configuration of one or more of the multiple points as being uplink resources and defined by the TDD configuration of one or more others of the multiple points as being downlink resources;
• and
• resolve, for the particular wireless communication device, each of the one or more conflicting resources as either an uplink resource to be used by the device, a downlink resource to be used by the device, or a resource not to be used by the device, based on one or more rules for optimizing use of conflicting resources.
