Technique for performing physical layer measurements

A mobile terminal operable to communicate over one or more distinct frequency resources, wherein said mobile terminal is configured to:

• decide to switch off reception on a first frequency resource;
• determine if there is data to be communicated over one or more second frequency resources within a time period, wherein the time period is based on a switching off time for switching off reception on the first frequency resource and wherein the first frequency resource is distinct from the one or more second frequency resources;
• if it is determined that there is no data to be communicated over the one or more second frequency resources within the time period, switch off reception on the first frequency resource;
• and
• if it is determined that there is data to be communicated over the one or more second frequency resources within the time period, delay switching off reception on the first frequency resource until after no further data is assigned to the mobile terminal.

A method performed in a mobile terminal, said method comprising:

• determining that the mobile terminal is to perform a physical layer measurement with regard to a first frequency resource;
• determining if there is data to be communicated over one or more second frequency resources within a time period defined by a time window preceding a measurement start time, wherein the time period is based on a switching on time for switching on reception on the first frequency resource and wherein the first frequency resource is distinct from the second frequency resources;
• and
• if it is determined that there is no data to be communicated over the one or more second frequency resources within the time period, performing the physical layer measurement on the first frequency resource and forming a quality measure of the first frequency resource based on the physical layer measurement;
• or
• if it is determined that there is data to be communicated over the one or more second frequency resources within the time period, modifying the physical layer measurement and forming a quality measure of the first frequency resource based on the modified physical layer measurement.

• deciding to switch off reception on a first frequency resource;
• determining if there is data to be communicated over the one or more second frequency resources within a time period, wherein the time period is based on a switching off time for switching off reception on the first frequency resource;
• if it is determined that there is no data to be communicated over the one or more second frequency resources within the time period, switching off reception on the first frequency resource;
• or
• if it is determined that there is data to be communicated over the one or more second frequency resources within the time period, delaying switching off reception on the first frequency resource until after no further data is assigned to the mobile terminal.
