干渉低減方法、基地局、移動局及びコンピュータ読取可能な媒体
Document Type and Number:
Japanese Patent JP5199417
Kind Code:
B2
Abstract:
Embodiments of the current invention reduce interference from a mobile station (UE) uplink transmission to a received broadcast downlink transmission through a network-based scheduling of time-slotted downlink broadcast transmissions, so that they do not occur concurrently with uplink transmissions. The invention allows low cost, low power UEs to be designed and built by use of the following techniques: (i) downlink broadcast transmissions are time-slotted; (ii) UEs operate either in half-duplex mode for transmission and reception of unicast services, or in full duplex mode where additional bandpass or additional highpass filtering can be applied to the DL unicast carrier; (iii) when unicast services are active for a UE, the UE informs the network of the broadcast services that are being decoded; and (iv) the network schedules unicast transmissions, broadcast transmissions, or both unicast and broadcast transmissions such that the uplink unicast transmission to a UE is never time-coincident with the broadcast transmissions to that UE.
