Abstract: Methods and apparatus for minimizing scheduling collisions between networks. In one embodiment, the networks are substantially unsynchronized, and during hybrid network operation (e.g., LTE and CDMA 1X operation), a mobile device can place CDMA 1X voice calls while registered with the LTE network. However, since the LTE and CDMA 1X networks are not coordinated, the mobile device will experience scheduling collisions. In one variant, the LTE network accounts for predictable behaviors (such as CDMA 1X paging), and schedules low priority tasks during likely time interval conflicts. Consequently, even though the mobile device must tune away from the LTE network to check CDMA 1X pages, overall LTE network performance is minimally affected.

Abstract: This disclosure relates to techniques for handling voice and data under uplink limited conditions in a wireless communication system. A wireless device and a base station may establish a wireless communication link. Transmission time interval bundling (TTI-B) may be enabled for uplink communications between the wireless device and the base station. It may be determined that the wireless device is experiencing uplink limited conditions. One or more rules prioritizing a first type of data over a second type of data for uplink communications may be enabled based on TTI-B being enabled and the wireless device experiencing uplink limited conditions.

Abstract: Methods to control reconfiguration of multiple radio access bearers in a mobile wireless device connected to a wireless network are described. The mobile wireless device is connected to the wireless network through a voice connection and a data connection simultaneously. The data connection is concurrently active with the voice connection. Transmission of one or more signaling messages for the data connection is delayed until the voice connection terminates. Representative signaling messages include messages that reconfigure a radio access bearer supporting the data connection and messages estimated to exceed a pre-determined transmission time interval.

Abstract: Avoiding conflicts between radio access technologies (RATs) in a device configured to operate according to multiple RATs. The device may be operated in a discontinuous reception (DRX) mode according to each of a first RAT and a second RAT using a shared radio. It may be determined that a conflicting wakeup time is scheduled according to DRX cycles of the first and second RATs. A subscriber identity of the device may be changed in response to determining that a conflicting wakeup time is scheduled according to DRX cycles of the first and second RATs.

Abstract: Performing cell re-selection by a wireless user equipment (UE) device. A first cell on which to camp may be selected. The UE may camp on the first cell in an idle-mode. The UE may be configured to perform searches for neighboring cells according to an idle-mode timeline while camping on the first cell. The UE may transmit a connection request to the first cell in order to transition the UE from the idle-mode to a connected-mode via the first cell. One or more searches for neighboring cells may be performed according to a connected-mode timeline after transmitting the connection request, in response to transmitting the connection request. The one or more searches may be performed before the UE establishes the connected-mode with the first cell.

Abstract: A method for delaying network reselection by a wireless communication device following a call failure is provided. The method can include determining an initiation of a voice call while connected to a first network. The method can further include participating in a circuit switched fallback (CSFB) procedure to transition from the first network to a second network in response to initiation of the voice call. The method can additionally include determining an occurrence of a call failure of the voice call. The method can also include, responsive to the call failure, barring reselection to the first network for a threshold barring period.

Abstract: A method for radio link control in a mobile wireless communication device. The mobile wireless device transmits a sequence of service requests to establish radio resources with a wireless communication network for a data packet in a pending data buffer. When no radio resources are allocated in response to the transmitted sequence of service requests, the mobile wireless device sets a minimum threshold for the pending data buffer, discards all pending data packets above the minimum threshold and discards the oldest pending data packet. The mobile wireless device repeats transmitting and discarding until a radio resource is allocated or the pending data packet buffer is empty. A retry interval between successive service requests is increased after transmitting each sequence of service requests until reaching a maximum retry interval value.

Abstract: Systems, apparatus and methods enable layer 2 (L2) relaying optimizations for a remote user equipment (UE) to receive system information (SI) from a relay UE. The relay UE may establish a sidelink communication channel with the remote UE that is in a radio resource control (RRC) idle state, an RRC inactive state, or an out-of-coverage (OOC) state with respect to the base station. The relay UE decodes a relay SI request received through the sidelink communication channel from the first remote UE. The relay SI request indicates requested system information. The Relay UE obtains the requested system information or a subset of the requested system information from a memory device or from the base station and encodes a relay SI response to send to the first remote UE. The relay SI response includes the requested system information or the subset of the requested system information.
