Interference-protected control message transmission in a mobile communications network

摘要

For protecting transmission of a control message (60) in a mobile communications network between a first access node (10a) and a user equipment, an indication of at least one protected time-slot for transmitting the control message may be transmitted in response to a need for transmitting the control message (60). The indication is transmitted between the first access node (10a) and a second access node (10b). Transmission of the indication prompts reduction of spectral interference caused by the second access node (10b) during the at least one protected time-slot (30).

1. A method of protecting transmission of a control message, in a mobile communications network, between a first access node and a user equipment, the method comprising:
in response to a need for transmitting the control message, transmitting, between the first access node and a second access node, an indication of at least one protected time-slot for transmitting the control message; the transmitting of the indication prompting reduction of spectral interference caused by the second access node during the at least one protected time-slot; wherein the transmitting of the indication of the at least one protected time-slot is part of negotiating of the at least one protected time-slot between the first access node and the second access node, the negotiating including:
sending, from the first access node to the second access node, a request message indicating a plurality of candidate time-slots from which the at least one protected time-slot is selected; andreceiving, from the second access node, an acknowledgement message positively and/or negatively acknowledging candidate time-slots from which the at least one protected time-slot is selected.
