Abstract
In a method of providing downlink retransmissions to a mobile station in a wireless communication network, the wireless communication network comprising a base station communicatively linked to a transparent relay station, the base station receives a request for a retransmission from the mobile station; schedules resources for the retransmission; signals scheduling information for the retransmission to the transparent relay station via a control link; and the transparent relay station receives the scheduling information for the retransmission on the control link; and sends the retransmission to the mobile station in a retransmit subframe on a retransmit frequency band.
Claims24
A method of providing downlink retransmissions to a mobile station in a wireless communication network, said wireless communication network comprising a base station communicatively linked to a transparent relay station, said method comprising:
- at said base station:
- receiving a request for a retransmission from said mobile station;
- identifying said mobile station as requiring relay assistance prior to scheduling resources for said retransmission, wherein said identifying said mobile station as requiring relay assistance comprises identify said mobile station as being near a cell edge;
- scheduling resources for said retransmission;
- and
- signalling scheduling information for said retransmission to said transparent relay station via a control link, wherein said transparent relay station transmits, using the scheduling information, said retransmission to said mobile device concurrently with said base station.
A method of providing downlink retransmissions to a mobile station in a wireless communication network, said wireless communication network comprising a base station communicatively linked to a transparent relay station, said method comprising:
- at said transparent relay station:
- receiving, from the base station, scheduling information via a control link for retransmission to a mobile station;
- and
- sending the retransmission to the mobile station in a retransmit subframe on a retransmit frequency band, wherein said transparent relay station transmits, using the scheduling information, said retransmission to said mobile device concurrently with said base station.
A base station for providing downlink retransmissions to a mobile station in a wireless communication network, comprising:
- one or more processors configured to:
- receive a request for a retransmission from said mobile station;
- identify said mobile station as requiring relay assistance prior to scheduling resources for said retransmission, wherein said identifying said mobile station as requiring relay assistance comprises identify said mobile station as being near a cell edge;
- schedule resources for said retransmission;
- and
- signal scheduling information for said retransmission to a transparent relay station via a control link, wherein said transparent relay station transmits, using the scheduling information, said retransmission to said mobile device concurrently with said base station.
A transparent relay station for providing downlink retransmissions to a mobile station in a wireless communication network, comprising:
- one or more processors configured to:
- receive, from a base station, scheduling information via a control link for a retransmission to a mobile station, wherein, prior to transmitting scheduling resources for said retransmission, the base station identifies said mobile station as requiring relay assistance including identifying said mobile station as being near a cell edge;
- and
- send the retransmission to the mobile station in a retransmit subframe on a retransmit frequency band, wherein said transparent relay station transmits, using the scheduling information, said retransmission to said mobile device concurrently with said base station.
