Abstract
Feedback information is received from user equipments served by jointly processed data streams of a coordinated multipoint transmission at each base station of base stations serving the jointly processed data streams, and scheduling data is decided for the user equipments based on the feedback information and scheduling rules. The scheduling rules may be determined at least in part by one of the base stations and scheduling decisions by the base stations may be synchronized. Scheduling decisions may be transferred via a backhaul link and/or over the air, which may include scheduling decisions for future transmission time intervals.
Claims14
An apparatus comprising:
- at least one processor and at least one memory including computer program code,
- wherein the at least one memory and the computer code are configured, with the at least one processor, to cause the apparatus to at least perform the following:
- receiving feedback information from a user equipment served by jointly processed data streams of a coordinated multi-point transmission from the apparatus and a second apparatus;
- and
- deciding scheduling data for the user equipment based on the feedback information and scheduling rules;
- wherein said coordinated multi-point transmission of jointly processed data streams comprises joint precoding of data and simultaneous transmission of the precoded data from the first and the second apparatus,
- wherein the scheduling rules assure that the apparatus and the second apparatus decide the same scheduling data for the coordinated multi-point transmission when receiving the same feedback information, and
- wherein the scheduling rules assure that the apparatus decides the scheduling data independently of the second apparatus and independently of a central unit.
A method comprising:
- receiving feedback information from a user equipment served by jointly processed data streams of a coordinated multi-point transmission from a first and a second apparatus;
- and
- deciding scheduling data for the user equipment based on the feedback information and scheduling rules;
- wherein said coordinated multi-point transmission of jointly processed data streams comprises joint precoding of data and simultaneous transmission of the precoded data from the first and the second apparatus,
- wherein the scheduling rules assure that the apparatus and the second apparatus decide the same scheduling data for the coordinated multi-point transmission when receiving the same feedback information, and
- wherein the scheduling rules assure that the apparatus decides the scheduling data independently of the second apparatus and independently of a central unit.
A computer program product embodied on a non-transitory computer-readable medium including a program for a processing device, comprising software code portions for performing the following steps when the program is run on the processing device:
- receiving feedback information from a user equipment served by jointly processed data streams of a coordinated multi-point transmission from a first and a second apparatus;
- and
- deciding scheduling data for the user equipment based on the feedback information and scheduling rules;
- wherein said coordinated multi-point transmission of jointly processed data streams comprises joint precoding of data and simultaneous transmission of the precoded data from the first and the second apparatus,
- wherein the scheduling rules assure that the apparatus and the second apparatus decide the same scheduling data for the coordinated multi-point transmission when receiving the same feedback information, and
- wherein the scheduling rules assure that the apparatus decides the scheduling data independently of the second apparatus and independently of a central unit.
