Scheduling

摘要

A method and apparatus for distributed coordinated scheduling (virtual joint scheduling) is provided. A primary entity is selected and it performs joint scheduling decisions according to information received from one or more coordinating secondary entities. Information received from user equipments served by the primary entity may be taken into account. The primary entity then forwards information of its joint scheduling decisions or some outcome quantity to the one or more secondary entities, each of which may perform their own localized scheduling decisions based on the information provided by the primary entity.

主权项

1. An apparatus for use in joint scheduling, the apparatus comprising a processing system, the processing system comprising at least one processor and at least one memory storing computer program code, in which the processing system is configured to cause the apparatus to at least:
calculate a joint schedule comprising a second schedule for serving a second user device using a resource by the apparatus and a first schedule for serving a first user device using the resource by a secondary transmission device different from the apparatus; and provide the joint schedule to the secondary transmission device, wherein: the calculating is based on a second scheduling decision affecting information of the second user device and a first scheduling decision affecting information of the first user device, the first scheduling decision affecting information is received from the secondary transmission device and comprises a first quality information and a second quality information, the first quality information is based on a first muting assumption for the apparatus, the second quality information is based on a second muting assumption for the apparatus different from the first muting assumption, the second scheduling decision affecting information comprises a third quality information and a fourth quality information, the third quality information is based on a third muting assumption for the secondary transmission device, and the fourth quality information is based on a fourth muting assumption for the secondary transmission device different from the third muting assumption.
