Radio Communication System, First Base Station And Second Base Station
Abstract: The present invention has an object to provide a communication system of improving the communication quality in a case where a plurality of communication devices having different sizes of ranges coexist, in which communication with a terminal device is possible, to thereby improve an entire throughput. In a case where a remote radio head (RRH) is installed in a coverage of a macro cell, an uplink resource transmitted from a user equipment (UE) to the macro cell, that is, an uplink carrier frequency band UL1 of the macro cell in a portion surrounded by a solid line is received not only by the macro cell but also by the RRH. Then, the macro cell combines a reception signal regarding the uplink resource of the macro cell, which has been received by the macro cell, and a reception signal regarding the uplink resource of the macro cell, which has been received by the RRH.

Specification
1. A radio communication system comprising a first base station (2102), a second bas
station (2103) different from the first base station (2102), and a user equipment (2101)
performing radio communication with the first base station (2102),
wherein the user equipment (2101) is configured to transmit a sounding reference signal,
wherein the first base station (2102) is configured to notify the second base station (2103) of a parameter regarding a method of transmitting the sounding reference signal, the parameter including a parameter specific to the user equipment (2101) and a parameter specific to a cell configured by the first base station (2102), and
wherein the second base station (2103) is configured to receive the sounding reference signal transmitted from the the user equipment (2101).
2. The radio communication system as claimed in Claim 1, wherein the parameter specific to the user equipment (2101) regarding the method of transmitting the sounding reference signal includes srs-bandwidth indicating a bandwidth of the sounding reference signal
3. The radio communication system as claimed in Claim 1, wherein the parameter specific to the user equipment (2101) regarding the method of transmitting the sounding reference signal includes transmissionComb indicating that the sounding reference signal is periodic.
4. The radio communication system as claimed in any one of Claims 1 to 3, wherein the parameter specific to the cell configured by the first base station (2102) regarding the method of transmitting the sounding reference signal includes Group-hopping-enabled indicating whether or not a sequence of the sounding reference signal is subjected to group hopping.
5. A first base station (2102) used in a radio communication system comprising the first base station (2102), a second base station (2103) different from the first base station (2102), and a user equipment (2101) performing radio communication with the first base station (2102),
wherein the first base station (2102) is configured to notify the second base station (2103) of a parameter regarding a method of transmitting a sounding reference signal, the parameter including a parameter specific to the user equipment (2101) and a parameter specific to a cell configured by the first base station (2102), the sounding reference signal being transmitted from the the user equipment (2101).
6. A second base station (2103) used in a radio communication system comprising a
first base station (2102), the second base station (2103) different from the first base station
(2102), and a user equipment (2101) performing radio communication with the first base station
(2102),
wherein the second base station (2103) is configured to be notified, from the first base station (2102), of a parameter regarding a method of transmitting a sounding reference signal, the parameter including a parameter specific to the user equipment (2101) and a parameter specific to a cell configured by the first base station (2102), the sounding reference signal being
