| Claim | An apparatus (100), comprising at least one processor (102), and at least one memory (104) storing instructions (106), the at least one memory (104) and the instructions (106) configured to, with the at least one processor (102), cause a serving secondary node (11) to transmit (202) to a target secondary node (12) a preparation request (PREP-REQ) indicating that an inter-secondary node conditional PSCell change is to be prepared. The apparatus (100) according to claim 1, wherein the instructions (106), when executed by the at least one processor (102), cause the serving secondary node (11) to receive (204) a preparation response (PREP-RESP) from the target secondary node (12). The apparatus (100) according to at least one of the claims 1 to 2, wherein the instructions (106), when executed by the at least one processor (102), cause the serving secondary node (11) to directly transmit (202) the preparation request (PREP-REQ) to the target secondary node (12) and/or to directly receive (204) the preparation response (PREP-RESP) from the target secondary node (12), e.g. via a signaling connection between the serving secondary node (11) and the target secondary node (12). The apparatus (100) according to at least one of the claims 1 to 3, wherein the instructions (106), when executed by the at least one processor (102), cause the serving secondary node (11) to transmit (202) the preparation request (PREP-REQ) to the target secondary node (12) via a master node (13) and/or to receive (204) the preparation response (PREP-RESP) from the target secondary node (12) via the master node (13). The apparatus (100) according to at least one of the preceding claims, wherein the instructions (106), when executed by the at least one processor (102), cause the serving secondary node (11) to determine (200), whether the serving secondary node (11) may directly transmit the preparation request (PREP-REQ) to the target secondary node (12). The apparatus (100) according to at least one of the preceding claims, wherein the instructions (106), when executed by the at least one processor (102), cause the serving secondary node (11) to receive a first information (I1) from a master node (13), the first information (I1) indicating whether the serving secondary node (11) may directly transmit the preparation request (PREP-REQ) to the target secondary node (12). The apparatus (100) according to at least one of the preceding claims, wherein the instructions (106), when executed by the at least one processor (102), cause the serving secondary node (11) to transmit (206) configuration information (CFG-INF) related to the inter-secondary node conditional PSCell change to a user equipment (14), e.g. over a signaling radio bearer that is using the radio interface of the serving secondary node. An apparatus (100a), comprising at least one processor (102a), and at least one memory (104a) storing instructions (106a), the at least one memory (104a) and the instructions (106a) configured to, with the at least one processor (102a), cause a target secondary node (12) to receive (250) from a serving secondary node (11) a preparation request (PREP-REQ) indicating that an inter-secondary node conditional PSCell change is to be prepared, and to transmit (252) to the serving secondary node (11) a preparation response (PREP-RESP). The apparatus (100a) according to claim 8, wherein the instructions (106a), when executed by the at least one processor (102a), cause the target secondary node (12) to transmit (254) a release request (REL-REQ) to the serving secondary node (12). An apparatus (100b), comprising at least one processor (102b), and at least one memory (104b) storing instructions (106b), the at least one memory (104b) and the instructions (106b) configured to, with the at least one processor (102b), cause a master node (13) to perform at least one of the following steps: a) transmit (270) to a serving secondary node (11) first information (I1) indicating whether the serving secondary node (11) may directly transmit a preparation request (PREP-REQ) indicating that an inter-secondary node conditional PSCell change is to be prepared to a target secondary node (12), b) receive (272) the preparation request (PREP-REQ) from the serving secondary node (11) and forward it to a target secondary node (12), c) receive (274) a preparation response (PREP-RESP) from the target secondary node (12) and forward it to the serving secondary node (11). A method comprising: transmitting (202), by a serving secondary node (11), to a target secondary node (12) a preparation request (PREP-REQ) indicating that an inter-secondary node conditional PSCell change is to be prepared. A method comprising: receiving (250), by a target secondary node (12), from a serving secondary node (11) a preparation request (PREP-REQ) indicating that an inter-secondary node conditional PSCell change is to be prepared, and transmitting (252), by the target secondary node (12), to the serving secondary node (11) a preparation response (PREP-RESP). An method comprising at least one of the following steps: a) transmitting (270), by a master node (13), to a serving secondary node (11) first information (I1) indicating whether the serving secondary node (11) may directly transmit a preparation request (PREP-REQ) indicating that an inter-secondary node conditional PSCell change is to be prepared to a target secondary node (12), b) receiving (272), by the master node (13), the preparation request (PREP-REQ) from the serving secondary node (11), and forwarding it to a target secondary node (12), c) receiving (274), by the master node (13), a preparation response (PREP-RESP) from the target secondary node (12) and forwarding it to the serving secondary node (11). An apparatus (100') comprising means (102') for causing a serving secondary node (11) to transmit (202) to a target secondary node (12) a preparation request (PREP-REQ) indicating that an inter-secondary node conditional PSCell change is to be prepared. Wireless communications system (10) comprising at least one serving secondary node (11) and at least one apparatus (100, 100a, 100b) according to at least one of the claims 1 to 10 or 14. |
