Apparatus and method for configuring radio resources in sleep mode

An apparatus for determining multiple-input multiple-output (MIMO) resource allocation, comprising:

• a processor;
• memory coupled to the processor storing instructions that when executed by the processor, cause the processor to:
• determine a type of a current interval for communicating with a serving base station during a sleep mode, the type of the current interval comprising one or both of an available interval and an unavailable interval within the sleep mode;
• determine that ranging is configured with the serving base station;
• and
• assign MIMO resources of the apparatus between the serving base station and at least one neighbor base station based at least in part on the type of the current interval, wherein assigning MIMO resources comprises assigning at least one transmitter chain to the serving base station for transmitting a ranging request, and wherein the MIMO resources comprise a virtual antenna port, or a physical antenna port, or a combination thereof associated with the apparatus.

A non-transitory computer-readable medium storing computer-executable code, the code executable by a processor to:

• determine a type of a current interval for communicating with a serving base station during a sleep mode, the type of the current interval comprising one or both of an available interval and an unavailable interval within the sleep mode;
• determine that ranging is configured with the serving base station;
• and
• assign MIMO resources of a mobile device between the serving base station and at least one neighbor base station based at least in part on the type of the current interval, wherein assigning MIMO resources comprises assigning at least one transmitter chain to the serving base station for transmitting a ranging request, and wherein the MIMO resources comprise a virtual antenna port, or a physical antenna port, or a combination thereof associated with the mobile device.
