Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured to include procedures to selectively release a portion of hybrid automatic repeat request (HARQ) memory based on the priority of each component carrier of the first connection when performing a radio tune-away to a second connection. For example, the UE may determine the amount of memory space associated with the HARQ processes for the second connection and selectively release a portion of HARQ memory based on the priority of each component carrier of the first connection when the determined amount of memory space is greater than the empty space of the HARQ memory.

A method for altering bandwidth consumption when receiving content in a user device includes determining a first user device status where the first user device status indicates whether content, which is being accessed by a content-rendering application, is viewable on a display of the user device, based on the first user device status, selecting one of a plurality of available alternative content segments, and receiving the selected content segment.

A method for selecting a data subscription on a multi-SIM (Subscriber Identity Module) mobile device includes: associating a plurality of application category groups with a plurality of active subscriptions; selecting an application to run; determining a category of the application; classifying the application into one of the plurality of category groups based on the category of the application; and automatically establishing a packet session for the application on the active subscription associated with the category group into which the application is classified.

This disclosure provides systems, methods and apparatus for wirelessly communicating with a wireless station. In one implementation, a mobile device comprises a memory unit configured to store communication information associated with communicating on at least one channel of a wireless network. The mobile device further comprises a processing system that is configured to establish communications with the wireless station via a communication link, retrieve the communication information from the memory unit, and to provide at least a portion of the communication information to the wireless station.

Increased power savings through collaborative search

Methods and devices are disclosed for enabling improved performance for page decodes on a SIM of a multi-SIM wireless communication device in which a shared radio frequency (RF) resource is used to read system information for a different SIM. After determining that a first SIM is using the shared RF resource to decode SIBs, the wireless device may receive information about an upcoming page decode time for monitoring a paging channel associated with the second SIM. The wireless device may obtain system information block (SIB) scheduling information associated with the first SIM, and may create a RF resource release gap during the system information read period based on the SIB scheduling information and the upcoming page decode time. Control of the RF resource may be released from the modem stack associated within the first SIM, and gained by a modem stack associated with the second SIM during the RF resource release gap.

Apparatus and methods for wireless communication in a wireless communication network include initiating a high speed downlink packet access (HSDPA) call to a user equipment (UE), applying a synchronization channel interference cancellation (SCHIC) algorithm to the HSDPA call, calculating synchronization channel (SCH) interference based on the application of the SCHICH algorithm to the HSDPA call, and eliminating the SCH interference from the HSDPA call.

Apparatus and method for SCH interference cancellation

Mesh communications aspects are disclosed in which multiple mobile devices located within a communication area perform direct communication to establish a mesh network. Each device node included in the mesh network provides power profile information to the other nodes on the network. As mesh messages are generated for transmission by the nodes onto the mesh network, an adaptive routing mechanism determines the transmission route based on the power profile of the proposed target node. The selective and adaptive routing determination allows for power to be efficiently conserved within the mesh network.

Methods and apparatus for wireless communication in a wireless communication network that includes receiving a synchronization channel (SCH) signal (including a primary synchronization channel (PSCH) signal, a secondary synchronization channel (SSCH) signal, and a primary scrambling code (PCH) signal) and a part of a common pilot channel (CPICH) signal in the same portion of the slot of the frame. The aspects include determining and summing the PSCH signal, SSCH signal, and PCH signal corresponding to the portion of the slot of the frame. The aspects also include de-spreading the pilot symbol over the portion of the slot of the frame based on the summed PSCH signal, the SSCH signal, and the PCH signal and estimating an estimated pilot symbol for the portion of the slot of the frame, where the estimated pilot symbol is a sum of the de-spread PSCH signal, de-spread SSCH signal, and de-spread PCH signal.

A method for determining an extension type of a system information block segment is described. A system information block segment of type extension is received in a system frame number. A byte in a system information block extension type lookup table corresponding to the system frame number of the system information block segment is calculated. A bit position in the system information block extension type lookup table corresponding to the system frame number is calculated. The extension type expected at the system frame number for the system information block segment is determined using the byte and the bit position.
