Method for performing a scheduling algorithm with a minimum resource parameter and method of calculating same
View Patent ↗The invention concerns a method for performing a scheduling algorithm in a scheduler ( 120 ) of a wireless communication system, comprising the steps of obtaining from a communication unit ( 200 ) a minimum resource parameter, wherein said minimum resource parameter indicates a minimum of resources allocated to the communication unit in a scheduling frame to meet a resource constraint and scheduling allocation units for radio access to the communication unit in a scheduling frame in accordance with the minimum resource parameter. The invention also concerns a method performed in a communication unit of a wireless communication network for generating a minimum resource parameter used in a scheduling algorithm to schedule allocation units in a scheduling frame for radio access to the communication unit ( 200 ) in accordance with the minimum resource parameter, comprising the steps of calculating the minimum resource parameter based on a determination of the power expended for processing of the scheduling frame, and signaling the calculated minimum resource parameter to the scheduler.

wherein the minimum resource parameter represents a sufficient quantity to exceed a power efficiency threshold in the scheduling frame, and
wherein the minimum resource parameter represents a minimum ratio of a number of information bits processed by the communication unit in a scheduling frame to an expended processing and operating power spent during the radio access by the communication unit in said scheduling frame.
2. The method according to claim 1 , wherein the minimum resource parameter represents a minimum number of information bits per scheduling frame for the user or the service.
3. The method according to claim 1 , wherein the minimum resource parameter is signaled periodically from the communication unit to the scheduler.
4. The method according to claim 1 , wherein the minimum resource parameter is signaled from the communication unit to the scheduler upon request by the scheduler.
5. The method according to claim 1 , wherein the obtaining of the minimum resource parameter is initiated by the communication unit upon fulfillment of power management conditions.
6. The method according to claim 1 , wherein the scheduling includes considering in addition at least one of the scheduling parameters of channel condition, amount of data available for transmission, Quality of Service (QoS), delay, data rate and carrier to interference ratio.
7. The method according to claim 1 , wherein the scheduling frame has at least one of a time division, frequency division or code division frame structure.
8. The method according to claim 1 , wherein the allocation units have a quantity of either one of transmittable information bits, Internet Protocol (IP) packets, code blocks or modulation symbols.
9. The method according to claim 1 , wherein the minimum resource parameter is signaled by the communication unit on a separate control channel associated to a data channel over which the allocation units are transmitted.
