Abstract:
Aspects described herein relate to communicating with multiple cells based on two separate subscriptions stored at the UE in a dual subscription dual standby (DSDS) mode, switching to communicate with the multiple cells in a dual subscription dual active (DSDA) mode, transmitting, to at least one of the multiple cells and based on a number of component carriers allowed for a subscription being exceeded by switching to communicate in the DSDA mode, assistance information to indicate a threshold amount of component carriers for the UE, and transmitting, to at least one of the multiple cells and based on the number of component carriers allowed for the subscription being exceeded by switching to communicate in the DSDA mode, a channel quality indicator (CQI) value for one or more cells of the multiple cells to request deactivation of one or more component carriers with, or release of, the one or more cells.
Abstract:
Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify occurrence of one or more collisions of paging of a first radio access technology (RAT) and paging of a second RAT, wherein the second RAT is associated with an asynchronous deployment; and/or identify a target cell of the second RAT to reduce occurrence of the collisions, wherein the target cell has at least one of a different temporal system frame numbering or a different system frame timing configuration than a serving cell of the wireless communication device, and wherein the target cell is identified using a primary common control physical channel (PCCPCH) of the target cell. Numerous other aspects are provided.
Abstract:
Examples described herein relate to enhancing data communication performance in a wireless communication network including a first subscription associated with a first radio access technology (RAT) and a second subscription associated with a second RAT, where the wireless communication device uses a same radio frequency (RF) resource to communicate over both the first RAT and the second RAT. The first RAT is used, in part, for data operations while the second RAT is used, in part, for voice operations. During idle state voice operations, the RF resource is reallocated from performing data operations to performing idle state voice operations, causing interruptions in the data operations. The wireless communication device adjusts at least one or a duration and an occurrence of the idle state voice operations to reduce the impact on the data operations.
Abstract:
Various methods for managing packet switched (PS) states on a mobile communication device may include performing, on a first subscription on the mobile communication device, a transition from a first radio access technology (RAT) to a second RAT, determining whether at least one application on the mobile communication device is utilizing on-demand PS services on the first subscription, and registering for circuit switched (CS) services but not PS services on the second RAT in response to determining that no applications on the mobile communication device is utilizing on-demand PS services on the first subscription.
Abstract:
Aspects described herein relate to using antenna-switched diversity (ASDIV) in wireless communications. A serving node can be communicated with using a serving radio access technology (RAT) and based on an ASDIV configuration, wherein the ASDIV configuration defines an antenna switching configuration including a state of one or more switches in an ASDIV switch group for switching between one or more antennas for the communicating based on sensing one or more parameters of the communicating. It can be determined whether a target RAT supports operating using a same ASDIV switch group as the serving RAT. A target node can be communicated with using the target RAT and based on the ASDIV configuration where the target RAT operates using the same ASDIV switch group as the serving RAT.
Abstract:
Aspects of the methods and apparatus include determining that a time-to-trigger (TTT) timer has expired, and determining that a serving radio access technology (RAT) received signal characteristic is less than a signal characteristic threshold when the TTT timer has expired. Further, the aspects include determining, in response to the serving RAT received signal characteristic being less than the signal characteristic threshold, that a target RAT frequency measurement associated with a Measurement Report Message (MRM) for performing an inter-RAT (IRAT) handover cannot be completed within a time limit according to a current measurement gap configuration. Also, the aspects include calculating a measurement gap duration sufficient to complete the target RAT frequency measurement associated with the MRM for performing the IRAT handover, and configuring a new measurement gap prior to the time limit, wherein the new measurement gap comprises the calculated measurement gap duration.
Abstract:
A multi-subscriber identity module (SIM) multi-standby user equipment (UE) improves recovery of an original operation of a first radio access technology (RAT) when the UE tunes away from the first RAT. In some instances, the UE communicates with the first RAT on a transmit chain and a receive chain and then tunes to a second RAT on the receive chain to monitor downlink communications or activities of the second RAT. The UE transmits on the first RAT over the transmit chain, while tuned to the second RAT. Thus, the UE continues to perform uplink transmission when the UE tunes away, which allows a base station of the first RAT to track the UE for downlink beam-forming.
Abstract:
A method of wireless communication includes returning to a base station after a handover failure. The method also includes measuring a length of time between receiving a handover command and returning to the base station. The method further includes setting a physical uplink channel transmit power based on the measured length of time. The physical uplink channel can be an enhanced physical uplink channel (E-PUCH) of a high speed uplink packet access (HSUPA) wireless network.
Abstract:
A method of wireless communication includes determining whether a serving cell signal strength is below a first threshold. The method also includes determining whether an inter/intra frequency neighbor cell signal strength is below a second threshold. The method further includes determining whether a number of idle traffic time slots for inter-radio access technology IRAT measurements is less than a third threshold. Finally, a frequency of IRAT measurements in time slot zero (TS0), a downlink pilot time slot (DwPTS), an uplink pilot time slot (UpPTS), and a gap (GP) is increased. The increase is based on the determined serving cell signal strength, the determined inter/intra frequency neighbor cell signal strength, and the determined number of idle traffic time slots.
Abstract:
A method of wireless communication includes returning to a base station after a handover failure. The method also includes receiving consecutive transmit power control (TPC) UP commands within a first predetermined time period. The method further includes receiving enhanced uplink dedicated channel uplink control channel (E-UCCH) instances within a second predetermined period. The method further includes increasing a TPC step size after receiving a first predetermined number of consecutive TPC UP commands during the first predetermined time period and after receiving a second predetermined number of E-UCCH instances during the second predetermined time period.
