Abstract
An apparatus (20) is associated with a telecommunications node (N) which serves a service area (S) which belongs to one set of plural sets of service areas comprising a network. The apparatus (20) divides a time resource for the node into plural phases in coordinated manner with other service areas. The apparatus (20) further generates a schedule for transmission/reception of user traffic for wireless terminals served by the node for plural consecutive phases. The schedule is generated so that during the plural consecutive phases the node can transmit and receive scheduled user traffic before receiving in the plural consecutive phases scheduling information from another node which serves another set of service areas.
Claims29
A method of scheduling wireless communication associated with a telecommunications node, the node serving a service area that belongs to one set of plural sets of service areas, the method comprising:
- dividing a time resource for the node into plural phases in coordinated manner with other service areas, with a predetermined number of consecutive phases forming one cycle;
- during a selected phase of the cycle, generating a schedule for transmission or reception of user traffic for plural user groups served by the node over a respective plural number of consecutive phase following the selected phase, the plural user groups comprising wireless terminals serve by the node;
- sending at least a portion of the schedule to one or more service areas neighboring a service area served by the node during the selected phase;
- and
- during the plural consecutive phases transmitting or receiving scheduled user traffic before receiving in the plural consecutive phases scheduling information from another node which serves another set of service areas.
An apparatus associated with a node of a radio access network, the node serving a service area which belongs to one set of plural sets of service areas comprising the network, the apparatus comprising electronic circuitry configured to:
- divide a time resource for the node into plural phases in coordinated manner with other service areas, with a predetermined number of consecutive phases forming one cycle;
- during a selected phase of the cycle, generate a schedule for transmission or reception of user traffic for plural user groups served by the node over a respective plural number of consecutive phase following the selected phase, the plural user groups comprising wireless terminals served by the node;
- send at least a portion of the schedule to one or more service areas neighboring a service area served by the node during the selected phase;
- and
- during the plural consecutive phases, transmit or receive scheduled user traffic before receiving in the plural consecutive phases scheduling information from another node which serves another set of service areas.
A method of operating a communications network comprising plural nodes, each node serving a service area which belongs to one set of plural sets of service areas comprising the network, the method comprising:
- in coordinated manner dividing a time resource for the plural nodes into plural phases, with a predetermined number of consecutive phases forming one cycle, with cycles of differing sets beginning with differing phases;
- for each of the plural nodes during a selected phase of the cycle selected separately for each of the plural nodes, generating a schedule for transmission or reception of user traffic for the plural user groups served by the node over a respective plural number of consecutive phases following the selected phase, the plural user groups comprising wireless terminals served by the node;
- from each of the plural nodes, sending at least a portion of the schedule to one or more service areas neighboring a service area served by the node during the selected phase;
- and
- each of the plural nodes transmitting or receiving scheduled user traffic before receiving in the plural consecutive phases scheduling information from a node which serves another set of service areas.
