Abstract: The various embodiments include a dual-SIM-dual-active (DSDA) device and methods for implementing robust receive (Rx) processing to resolve radio frequency coexistence interference between two subscriptions operating on the DSDA device. The DSDA device may detect when a subscription (the "aggressor") de-senses the other subscription (the "victim") as a result of the aggressor's transmissions, and in response, implement robust Rx processing to mitigate the effects of de-sense on the victim while causing minimal impact to the aggressor.

Abstract: Wireless communications systems and methods related to allocating resource blocks and resource block groups in a system band in order to reduce overhead associated with resource allocation. To reduce overhead, the wireless communication device communicates a signal in a control channel that indicates a general area and a resource block in the general area that stores data. The wireless communication device then communicates multiple resource blocks that include the resource block and communicates the data in the resource block using the signal. To reduce overhead, the wireless communication device also communicates multiple mappings for each resource block group into a set of resource blocks and a signal in a control channel that selects one of the multiple mappings. The communication device then determines resource blocks that are included in the resource block group according to the mapping, and communicates data in these resource blocks.

Abstract: Interference cancellation at a user equipment includes performing channel estimation for each component of an aggregate received signal using at least one received midamble of at least one time slot. The aggregate received signal is received from at least one Node B. A combined channel is computed for each channelization code based on the channel estimation. A linear transfer function is obtained for all user equipment within a cell. This linear transfer function includes a combined channel for each channelization code. An equalization matrix is derived from the linear transfer function and then applied to the aggregate received signal to obtain the component intended for the user equipment.
