Methods And Apparatus For Determining Participants In Coordinated Multi-Point Transmission
First Claim
1. An apparatus comprising:
- a processing system comprising at least one processor and a memory storing a set of computer instructions, wherein the processing system is configured to;
cause the apparatus to receive information indicative of propagation delay variation between at least a first transmission and a second transmission received at a user equipment, the first transmission being received from a first transmission point and the second transmission being received from a second transmission point;
evaluate the information relating to the propagation delay variation; and
based on the evaluation, determine if the second transmission point is acceptable as a participant in a cooperative multi-point joint processing transmission to the user equipment.

Abstract
Systems and techniques for communication using coordinated multi-point transmission. In one embodiment, an apparatus comprises at least one processor and a memory storing a set of computer instructions. The processor is configured to cause the apparatus to receive information relating to a propagation delay variation between at least a first transmission and a second transmission received at a user equipment. The first transmission is received from a first transmission point and the second transmission is received from a second transmission. The information relating to the propagation delay variation is evaluated and, based on the result of the evaluation, a determination is made as to whether the second transmission point is acceptable as a participant in a cooperative multi-point joint processing transmission to the user equipment.

8. An apparatus comprising:
a processing system comprising at least one processor and a memory storing a set of computer instructions, wherein the processing system is configured to; cause the apparatus to determine variation information relating to propagation delay variation between at least a first transmission from a first transmission point and a second transmission from a second transmission point, in which the determination of the variation information is based at least in part on a propagation delay; cause the apparatus to report the variation information to a network element managing coordinated multi-point transmission in a communication network; and cause the apparatus to report channel state information, the channel state information comprising an indication as to whether the channel exhibits an excessive propagation delay spread. - View Dependent Claims (9, 10, 11, 12, 13, 14)
