Method of channel management for multiple component carrier in mobile communication system

Номер: US20120039200A1

Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. In DL, a base station determines a component carrier (CC) of an unstable radio channel state, stops data retransmission by the CC, and notifies a terminal of retransmission stop. In UL, the base station determines a CC of an unstable radio channel state and instructs the terminal to stop data retransmission by the CC, and the terminal stops the data retransmission and initializes a retransmission buffer. Using the channel management methods in the mobile communication system employing the multicarrier structure, an increase in the number of unnecessary retransmissions is prevented, so that unnecessary retransmission and power consumption of the terminal can be reduced and the waste of radio resources and the degradation of base station performance due to unnecessary retransmission can be prevented.

Network Coexistence through Active Superframe Interleaving

Номер: US20120063395A1
Автор: Jin-Meng Ho
Принадлежит: Texas Instruments Inc

Embodiments of the invention provide coexistence among independent networks through active superframe interleaving. Network hubs and devices exchange signals over a selected channel only during active superframes of their network. Network hubs broadcast coexistence information during their active superframes. A hub of network B desiring to use the selected channel first attempts to fit its active superframes within network A's inactive superframes, if available. If network A is not providing inactive superframes, then the network B hub determines whether network A is willing to coexist using active superframe interleaving on the channel. If so, the network B hub sends an interleave request message to the network A hub, which may accept the message and send back an interleave response message. The network A hub then offers new inactive superframes, and the network B hub adapts the transmissions and receptions of network B to fit within these inactive superframes.

A method and apparatus for reducing spectrum interference between wireless networks. This is realized by arranging at least one sub-coordinating apparatus, namely, a monitoring apparatus, in respective wireless network, and by arranging a coordinating apparatus, namely, an allocation apparatus in the whole network. Wherein, the sub-coordinating apparatus monitors the spectrum utilization situation of the wireless network where it is located, reports it to the coordinating apparatus, and requests the coordinating apparatus for spectrum resource when new spectrum resource is needed. The coordinating apparatus maintains the spectrum utilization information of each wireless network, and allocates appropriate spectrum resource to the sub-coordinating apparatus which requests spectrum resource based on the maintained information. Therefore, the interference of inter-wireless networks is reduced or even avoided through such overall management that the coordinating apparatus allocates corresponding spectrum resources to a plurality of wireless networks capable of sharing spectrum resources.

The method of claim 1 , wherein coordinating the transmission blanking on the forward link over the first carrier bandwidth further comprises:determining a timing of a control transmission over the second carrier bandwidth and coordinating the transmission blanking based on the determined timing of the control channel transmission over the second carrier bandwidth.4. The method of claim 1 , wherein coordinating the transmission blanking on the forward link over the first carrier bandwidth further comprises:determining a data transmission over the second carrier bandwidth and wherein coordinating the transmission blanking on the forward link over the first ...
