Abstract: The present disclosure presents an improved method and apparatus for re-transmission of reconfiguration messages. For example, the disclosure presents a method for detecting that a reconfiguration complete message is transmitted from a user equipment (UE) to a network and initiating a reconfiguration re-transmission timer upon the detection. In addition, such an example method, may include determining that the UE has not received a layer two acknowledgement (L2 ACK) message for the transmitted reconfiguration complete message from the network prior to expiration of the reconfiguration re-transmission timer and triggering a cell update message to the network in response to the determination that the UE has not received the L2 ACK message. As such, improved re-transmission of reconfiguration messages may be achieved.

Abstract: The present disclosure presents a method and apparatus for dynamically configuring a cell update message at a user equipment (UE). For example, the method may include determining that a size of the cell update message at the UE is above a threshold value after a “measured results on random access channel (RACH)” information element (IE) is excluded from the cell update message. Furthermore, such an example method may include removing one or more IEs from the cell update message until the size of the cell update message is at or below the threshold value. As such, dynamic configuration of a cell update message at a UE is achieved.

Abstract: 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.

Abstract: In various aspects of the disclosure, an improved tune-away technique is utilized by a user equipment (UE) for wireless communication during a signaling procedure for a primary subscription with reduced impact on paging performance of one or more secondary subscriptions. The UE performs a signaling procedure including receiving at least one protocol data unit (PDU) of a signaling radio bearer (SRB) message from a first network associated with the first subscription. The UE further determines a message type of the SRB message based on the at least one received PDU. If the message type indicates that the SRB message includes a signaling non-critical message, the UE further performs a tune-away procedure to communicate with a second network associated with the second subscription, while the signaling procedure is ongoing.

Abstract: Aspects of the disclosure provide apparatus and methods of inter-system measurements operable at a user equipment (UE) in a wireless communication network. The UE establishes a connection with a network node in a first wireless communication network utilizing a first radio access technology (RAT), wherein the UE is capable of measuring a plurality of frequency bands of a second RAT greater in number than a measurement capability report limit of the first RAT. The UE further selects a subset of the plurality of frequency bands of the second RAT to be included in a measurement capability information element (IE) based on information provided by the network node and information stored at the UE. The UE further transmits the measurement capability IE to the network node.

Abstract: Aspects of the present disclosure provides methods, corresponding apparatus and program products, for improving LTE to another network (e.g., Wideband Code Division Multiple Access, WCDMA) redirection search time. A user equipment (UE) may receive a redirection message indicating a frequency for a potential target cell and may attempt to acquire a target cell based on the frequency indicated in the redirection message. IF the UE's attempt to acquire a target cell based on the indicated frequency fails to find a suitable target cell, the UE may attempt to find a suitable target cell using a heuristic approach involving one or more frequencies different than the frequency indicated in the redirection message.

Abstract: A method includes receiving a dormancy request from an application executing at a communication device. In response to the dormancy request, a message is sent from the communication device to a radio network controller. The message indicates that a data session has ended. After expiration of a time period following sending of the message, state information is provided to the application. The state information indicates whether the communication device is in a low-power state.

Abstract: In various aspects, the disclosure provides user equipment (UE) capable of conducting a public land mobile network (PLMN) search by determining a paging schedule for a serving cell of the UE, the serving cell being associated with a first PLMN and the paging schedule defining one or more paging occasions. The UE may initiate a search for a second PLMN between consecutive paging occasions, and may read information blocks on a broadcast channel of a cell of the second PLMN. The UE may discontinue reading a partially-read information block when the partially-read information block is scheduled for transmission at least partially concurrently with a paging occasion on the serving cell if the partially-read information block does not include information for identifying the second PLMN. The UE may ignore the first paging occasion when the partially-read information block includes the information for identifying the second PLMN.
