Method and Apparatus for Performing Radio Measurements in Autonomous Gaps in Multi-Connectivity Scenarios

摘要

In one aspect of the teachings herein, a wireless device operating in a multi-connectivity configuration with respect to an associated wireless communication network applies asymmetrical blanking to two or more of its multi-connectivity connections in conjunction with acquiring system information for a target cell during one or more measurement gaps. “Blanking” as used here implies an interruption in downlink reception, or an interruption in uplink transmission, or both, and arises as a consequence of the measurement gaps used by a wireless device to make measurements on target-cell signals. Asymmetrical blanking results in, for example, the wireless device sending more or less acknowledgment/non-acknowledgment, ACK/NACK, signaling on one of the connections relative to another one of the connections, when acquiring the target-cell system information. In some embodiments, asymmetrical blanking is triggered and/or configured by the network, while in other embodiments it is triggered and/or configured by the wireless device.

主权项

1. A method at a wireless device configured for operation in a wireless communication network that supports multi-connectivity operation where the wireless device has at least two multi-connectivity connections with the network, and where each connection corresponds to a different cell group, CG, in the network, said method comprising:
determining that system information is to be acquired for a target cell; determining that asymmetrical blanking is to be applied by the wireless device to two or more connections of the at least two multi-connectivity connections, in association with acquiring the system information; and applying asymmetrical blanking to the two or more connections, according to an asymmetrical blanking configuration.
