The communication apparatuses include a communication apparatus which comprises a receiver, which in operation, receives from a base station a first resource information indicating a first resource allocated by the base station; and a transmitter, which in operation, transmits to a target communication apparatus or a plurality of target communication apparatuses including the target communication apparatus a second resource information indicating a second resource allocated to at least the target communication apparatus, the second resource including a whole or a part of the first resource. ## Claims ### Claim 1 A communication apparatus, comprising: circuitry, which in operation, determines a second resource based on control information transmitted from another communication apparatus, the second resource being a part of a first resource which is a resource pool used for a sidelink communication and which is configured at a base station; and a transmitter, which in operation, transmits on the second resource data to the another communication apparatus. ### Claim 2 (depends on 1) The communication apparatus according to claim 1, wherein the control information is transmitted by a dedicated signaling from the another communication apparatus. ### Claim 3 (depends on 1) The communication apparatus according to claim 1, wherein when there is a presence of an access stratum (AS) level connection between the communication apparatus and the another communication apparatus, the control information is transmitted from the another communication apparatus. ### Claim 4 (depends on 1) The communication apparatus according to claim 1, wherein when there is no presence of an access stratum (AS) level connection with the another communication apparatus, the AS level connection with the another communication apparatus is established before transmitting the second resource information. ### Claim 5 (depends on 1) The communication apparatus according to claim 1, wherein the control information includes a field indicating an expiration time, and wherein in response to a period of time following the transmission of the control information exceeding the expiration time, the communication apparatus withdraws the second resource to be used for a transmission of the data. ### Claim 6 A communication method, comprising: determining a second resource based on control information transmitted from another communication apparatus, the second resource being a part of a first resource which is a resource pool used for a sidelink communication and which is configured at a base station; and transmitting on the second resource data to the another communication apparatus. ### Claim 7 (depends on 6) The communication method according to claim 6, wherein the control information is transmitted by a dedicated signaling from the another communication apparatus. ### Claim 8 (depends on 6) The communication method according to claim 6, wherein when there is a presence of an access stratum (AS) level connection between the communication apparatus and the another communication apparatus, the control information is transmitted from the another communication apparatus. ### Claim 9 (depends on 6) The communication method according to claim 6, wherein when there is no presence of an access stratum (AS) level connection with the another communication apparatus, the AS level connection with the another communication apparatus is established before transmitting the second resource information. ### Claim 10 (depends on 6) The communication method according to claim 6, wherein the control information includes a field indicating an expiration time, and wherein in response to a period of time following the transmission of the control information exceeding the expiration time, a communication apparatus withdraws the second resource to be used for a transmission of the data. ### Claim 11 A communication apparatus, comprising: circuitry, which in operation, determines a second resource, the second resource being a part of a first resource which is a resource pool used for a sidelink communication and which is configured at a base station; and a transmitter, which in operation, transmits control information relating to the second resource to another communication apparatus. ### Claim 12 (depends on 11) The communication apparatus according to claim 11, wherein the control information includes a field indicating an expiration time, and wherein in response to a period of time exceeding the expiration time, the communication apparatus withdraws the second resource to be used for a data transmission.
