Abstract: This disclosure relates to TTI bundling for downlink communication. According to one embodiment, a base station and a wireless device may establish a wireless communication link. The base station may determine to enable TTI bundling for downlink communication for at least one carrier of the wireless communication link. The base station may provide an indication to the wireless device to enable TTI bundling for downlink communication for the determined carrier(s) of the wireless communication link. The base station may subsequently transmit TTI bundle downlink communications to the wireless device via the determined carrier(s).

Abstract: A wireless communication system is presented for future scheduling of secondary component carrier(s) (SCC) during carrier aggregation in LTE wireless communications. A primary component carrier in a first subframe can be used to indicate at what future subframe SCC data may exist for the mobile device (e.g., UE, etc.). The UE can then leave off all SCC receive circuitry until the future subframe, when it can turn on all needed SCC receive circuitry to receive the SCC data. After receiving the SCC data, the UE can again power off the SCC receive circuitry.

Abstract: This disclosure relates to carrier aggregation using separate RLC entities for different component carriers. According to one embodiment, a base station and a wireless device may establish a primary component carrier and at least one secondary component carrier according to a first radio access technology. Separate radio link control entities may be established for the primary component carrier and the secondary component carrier. Data communicated between the base station and the wireless device may be routed by way of the primary component or the secondary component carrier based on differing characteristics of the component carriers, and the RLC entities may treat downlink data differently on the primary component carrier and the secondary component carrier based on the differing characteristics of the component carriers.

Abstract: Electronic devices may be provided that contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to antennas. An electronic device may include a baseband processor and other storage and processing circuitry that implements protocol stacks for handling multiple radio access technologies. The storage and processing circuitry may use the transceiver circuitry to convey data using a first radio access technology while periodically interrupting the conveying of the data to monitor a paging channel using a second radio access technology. In performing the paging channel monitoring operations, the storage and processing circuitry may enforce a time limit that ensures that operations using the first radio access technology are not disrupted more than desired.

Abstract: A method performed at a network component for indicating a number of grants in a transmission and a corresponding method performed at a station to limit a search for the grants to the number indicated in the transmission. In one embodiment, the transmission includes physical downlink control channel (PDCCH) information and modified cyclic redundancy check (CRC) information, the modified CRC information being generated from CRC information for the PDCCH information and a modifier representing a number of grants. The station determines the number of grants from the modified CRC information, performs a search for a first grant within the PDCCH information and terminates the search upon identifying the first grant, when the number of grants is the first number.

In other configurations, the first antenna may be used to support operations with a first of the radio access technologies while the second antenna is used to support operations with a second of the radio access technologies.

Abstract: Managing radio resources across dual networks includes a wireless mobile device connecting to a first wireless network using a first radio access technology. The wireless device may notify the first network of a capability to be temporarily non-responsive to the first network while maintaining a signaling connection to the first network. The wireless device may communicate with a second network. The wireless device may return to communicating with the first network subsequent to communicating with the second network, and in response to communicating with the second network for less than a predetermined amount of time, the wireless device may send a scheduling request to the first network. In response to receiving a grant acknowledgement from the first network, the wireless device may send a buffer status report that includes a value such as zero to indicate that the wireless device has returned to and can communicate with the first network.

Abstract: A device and method generates a hopping scheme for mobile stations of a wireless network. The method includes receiving a number of channels N of the wireless network. The method includes generating a shuffling matrix as a function of the number of channels N, each row of the shuffling matrix being indicative of a respective one of the mobile stations, each column of the shuffling matrix being indicative of a respective broadcast time of a discovery signal in a hopping scheme. The method includes generating the hopping scheme for the mobile stations in the channels as a function of the shuffling matrix. The hopping scheme maximizes an interval between two consecutive broadcast times that any two of the mobile stations are assigned to transmit discovery signals on adjacent channels.

Abstract: Methods and apparatus for synchronizing operational state during hybrid network operation. In one embodiment, the various access technologies that makeup the hybrid network not fully synchronized. Thus, a wireless device operating in a mixed mode must be capable of managing synchronization across multiple access technologies. The wireless device is configured to estimate an expected “tune-away” period when disengaging with a one access technology to address events (for example, link maintenance, calls, data, and the like) or perform monitoring on a second access technology. The estimate is then used by the device to adjust its operational parameters on the technology from which it is tuning away. This ensures smooth switching away from and back to the various network technologies.
