Abstract
A method includes receiving information at a user equipment from a first apparatus, the information indicating to the user equipment is to communicate with a second apparatus.
Claims15
A method comprising:
- monitoring, by a user equipment, at least one control channel from a macro base station, wherein the at least one control channel provides information indicating to the user equipment and allowing the user equipment to communicate in uplink with a non-macro base station, said information including at least a carrier ID field value of the non-macro base station;
- receiving the information at the user equipment in downlink from the macro base station, said information being contained within a downlink control signaling, said information further including transmit power control commands to be used by the user equipment;
- sending a physical uplink control channel message to the macro base station based on the transmit power control commands;
- receiving an adjusted/modified transmission power control command value from the macro base station for use in communicating with the non-macro base station;
- and
- communicating by the user equipment in uplink with the non-macro base station based on the adjusted/modified transmission power control command value,
- whereby the user equipment receives downlink transmissions from the macro base station and sends uplink transmissions to the non-macro base station to actively decouple uplink and downlink cell selection to permit separate optimizations for uplink and downlink communications.

A method comprising:
- transmitting information to a user equipment in downlink from a macro base station in at least one control channel to be monitored by the user equipment, the information indicating to the user equipment and allowing the user equipment to communicate in uplink with a non-macro base station, said information being contained within a downlink control signaling and including at least a carrier ID field value of the non-macro base station, said information further including transmit power control commands to be used by the user equipment;
- receiving a physical uplink control channel message from the user equipment based on the transmit power control commands;
- and
- sending an adjusted/modified transmission power control command value to the user equipment for use in communicating with the non-macro base station,
- whereby the user equipment receives downlink transmissions from the macro base station and sends uplink transmissions to the non-macro base station to actively decouple uplink and downlink cell selection to permit separate optimizations for uplink and downlink communications.
2 more elements
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus to perform at least the following:
- monitor at least one control channel from a macro base station, wherein the at least one control channel provides information indicating to the apparatus and allowing the apparatus to communicate in uplink with a non-macro base station, said information including at least a carrier ID field value of the non-macro base station;
- receive the information in downlink from the macro base station, said information being contained within a downlink control signaling said information further including transmit power control commands to be used by the user equipment;
- send a physical uplink control channel message to the macro base station based on the transmit power control commands;
- receive an adjusted/modified transmission power control command value from the macro base station for use in communicating with the non-macro base station;
- and
- communicate with the non-macro base station based on the adjusted/modified transmission power control command value,
- whereby the apparatus receives downlink transmissions from the macro base station and sends uplink transmissions to the non-macro base station to actively decouple uplink and downlink cell selection to permit separate optimizations for uplink and downlink communications.
