COORDINATED MULTI-POINT COMMUNICATIONS SYSTEM AND METHODS FOR CONTROLLING COORDINATED MULTI-POINT TRANSMISSION AND RECEPTION
First Claim
1. A coordinated multi-point communications system, comprising:
- a first center site, operative to serve one or more user equipment located under coverage of a first cluster; and
a plurality of first remote devices, connected to the first center site and operative to receive downlink signals from the first center site and transmit the downlink signals to the one or more user equipment and/or receive uplink signals from the one or more user equipment and transmit the uplink signals to the first center site,wherein the first center site and the first remote devices form the first cluster to support coordinated multi-point transmission and reception for simultaneously transmitting and/or receiving the downlink and/or uplink signals to and/or from the one or more user equipment, andwherein at least one of the first remote devices is further connected to at least a second center site of a second cluster adjacent to the first cluster.

Abstract
A coordinated multi-point communications system is provided. A first center site is operative to serve one or more user equipment located under coverage of a first cluster. Multiple first remote devices are connected to the first center site and operative to receive downlink signals from the first center site and transmit the downlink signals to the one or more user equipment and/or receive uplink signals from the one or more user equipment and transmit the uplink signals to the first center site. The first center site and the first remote devices form the first cluster to support coordinated multi-point transmission and reception for simultaneously transmitting and/or receiving the downlink and/or uplink signals to and/or from the one or more user equipment, and at least one of the first remote devices is further connected to at least a second center site of a second cluster adjacent to the first cluster.

13. A method for controlling coordinated multi-point transmission and reception in a wireless communications system, comprising:
-
connecting a plurality of first remote devices to a first center site to form a first cluster to support coordinated multi-point transmission and reception, wherein the first center site is operative to serve one or more user equipment located under coverage of the first cluster and the first remote devices are controlled by the first center site to simultaneously transmit downlink signals to the one or more user equipment and/or simultaneously receive uplink signals from the one or more user equipment; and connecting at least one second remote device to the first center site, wherein the second remote device belongs to a second cluster adjacent to the first cluster.

18. A method for controlling coordinated multi-point transmission and reception in a wireless communications system, comprising:
-
simultaneously transmitting first downlink signals to a first user equipment located in coverage boundary of a first cluster via at least one of a plurality of first remote devices and at least one of a plurality of second remote devices, wherein the first remote devices are connected to a first center site to form the first cluster and the first user equipment is served by the first center site, wherein the second remote devices are connected to a second center site to form a second cluster, and wherein transmission of the first downlink signals is initiated and controlled by the first center site. - View Dependent Claims (22, 23)
