Methods, systems, and devices are described for wireless communication at a device. A wireless device may be configured with a transmission time interval (TTI) bundling parameter. The device may then identify one or more resources for an uplink (UL) control channel based on the TTI bundling parameter (e.g., using either an implicit or an explicit indication from another wireless node such as a serving cell of a base station) and transmit the UL control channel using the identified resources. The device may also identify a downlink control information (DCI) format based on the TTI bundling parameter. For example, a resource allocation granularity level may be associated with the bundling parameter, and the length of a DCI field may depend on the resource allocation granularity level.

The embodiment of the invention discloses a channel content change notice method and a channel re-detection method. The channel content change notice method comprises the following steps: a base station determines that the bearing content of a configured point-to-multipoint control channel (MCCH) of the multimedia broadcast multicast service (MBMS) changes and sends the notice that the bearing content of the MCCH changes to the terminal through a physical downlink control channel (PDCCH); and the terminal re-detects the MCCH according to the notice after the PDCCH receives the notice. The embodiment of the invention discloses a channel re-detection system and equipment. By adopting the invention, the terminal can know whether the bearing content of the MCCH changes and re-detects the MCCH when the bearing content changes, without periodically re-detecting the MCCH, thus being beneficial to saving the resources of the terminal.

In a base station (100), when the number of layers employed is 1 and the employed antenna port and the antenna port used for transmitting the allocation control signal are the same, a transmission controller (102) sets a first data resource region inside a first resource region, in a resource block group (RBG), that can be used for the control channel or the data channel. When the number of layers employed is 1 and the employed antenna port and the antenna port used for transmitting the allocation control signal are different, a transmission controller (102) sets a second data resource region inside the first resource region in the RBG. The second data resource region is larger than the first data resource region.

The invention discloses a method for accessing and exiting frequency spectrum of a hybrid cognitive network by adopting the conventional wireless communication technology. Wireless communication adopts a multi-band mode and comprises an authorization network and a cognitive network; a special node is included in a cognitive user; centralized frequency spectrum perception and channel allocation and management are performed by using a public control channel and the special node when the cognitive user is accessed; and the method for exiting of the cognitive user adopts a distributed mode after a channel is re-occupied by the authorization network. By adopting centralized access allocation, distributed perception exiting, and a point-to-point communication method, and the functions of accessing and exiting are separated to ensure the cognitive working efficiency and the complexity of a cognitive network system. Moreover, each node shares same hardware resources, so the special node can be arbitrarily selected or replaced, and the comprehensive reliability of the system can be also improved.
