    Abstract: A radio communication device capable of randomizing both inter-cell interference and intra-cell interference. In this device, a spreading section primarily spreads a response signal in a ZAC sequence set by a control unit. A spreading section secondarily spreads the primarily spread response signal in a block-wise spreading code sequence set by the control unit. The control unit controls the cyclic shift amount of the ZAC sequence used for the primary spreading in the spreading section and the block-wise spreading code sequence used for the secondary spreading in the spreading section according to a set hopping pattern. The hopping pattern set by the control unit is made up of two hierarchies. An LB-based hopping pattern different for each cell is defined in the first hierarchy in order to randomize the inter-cell interference. A hopping pattern different for each mobile station is defined in the second hierarchy to randomize the intra-cell interference.

The computing device may also include a general purpose radio that may facilitate general wireless connectivity between the computing device and other devices. The general purpose radio may listen for any messages that are intended for the accessory radio while the accessory radio is in the sleep state. The general purpose radio may activate the accessory radio in response to the general purpose radio receiving a message, while the accessory radio is in the sleep state, that satisfies at least one activation condition.

  • Patent number: 10298288
    Abstract: This disclosure relates to antenna switching circuitry and other radio frequency (RF) front-end circuitry. In one embodiment, the antenna switching circuitry includes a multiple throw solid-state transistor switch (MTSTS), a multiple throw microelectromechanical switch (MTMEMS), and a control circuit. The MTSTS is configured to selectively couple a first pole port to any one of a first set of throw ports and to selectively couple a second pole port to any one of a second set of throw ports. The MTMEMS is configured to selectively couple a third pole port to any one of a third set of throw ports. The control circuit is configured to control the selective coupling of the MTSTS and the MTMEMS. In this manner, the control circuit may operate the antenna switching circuitry so that RF signals may be routed in accordance with Long Term Evolution (LTE) Multiple-Input and Multiple-Output (MIMO) and/or LTE diversity specifications.
