Abstract:
A method and apparatus for wireless communication avoids handover to a non-best neighbor cell. While in a connected mode of operation, a user equipment (UE) determines whether a neighbor cell is the best cell. When the neighbor cell is not the best cell and a time to trigger (TTT) associated with the neighbor cell expires, the UE delays reporting the non-best neighbor cell to a network.
Abstract:
A method and/or apparatus for wireless communication in a multi-SIM user equipment includes receiving a list of neighboring base stations from a serving base station of a first SIM. The serving base station of a second SIM is identified and a final target base station is determined for a cell reselection procedure and/or cell change order procedure from among the neighboring base stations and the serving base station of the second SIM.
Abstract:
A method of wireless communication includes receiving a first grant and first high speed downlink data before tuning away from a first RAT and storing the first high speed data in a buffer corresponding to a first HARQ ID indicated in the first grant after failing to decode the first high speed downlink data. The method also includes receiving a second grant and second high speed data after tuning back to the first RAT after tuning away to a second RAT. The method further includes determining whether the second high speed data is a new transmission or a retransmission of the first high speed data without processing a new data indicator.
Abstract:
A user equipment (UE) expedites cell reselection from a higher priority radio access technology (RAT) to a lower priority RAT. In one instance, the UE determines whether a serving cell signal quality exceeds a threshold when a UE is in idle mode. The serving cell is associated with a higher priority RAT. In another instance, the UE performs an expedited search and measurement of cells of a lower priority RAT when the serving cell signal quality is below the threshold by commencing search and measurement before a next discontinuous reception (DRX) cycle scheduled for measurement.
Abstract:
An apparatus and method for wireless communication extends a measurement gap in a high speed data network. When it is determined a high speed data channel will fall within a measurement gap, the monitoring of the grant channel corresponding to the high speed data channel is skipped. The measurement gap is extended for inter radio access technology (IRAT) measurement to include the time slot containing the grant channel when the time slot only includes the grant channel corresponding to the high speed data channel that will fall in the measurement gap.
Abstract:
A method of wireless communication includes controlling a rate of forced measurement gap requests for a serving radio access technology (RAT) to measure a target RAT based on an impact to quality of service on the serving RAT by forced measurement gaps.
Abstract:
A method of wireless communication includes determining when all HARQ processes are associated with packages for retransmission. The method also includes determining when no new packages are pending in a UE buffer and when a received grant is insufficient for retransmission of any of the HARQ processes. The method further includes determining possible block sizes supported by each allocated time slot identified in the received grant. The method still further includes retransmitting the package of a selected HARQ process with maximum available power.
Abstract:
A method of wireless communication includes receiving a set of frequency layers for intra radio access technology (RAT) inter-frequency cell reselection and/or a set of frequency layers for inter RAT frequency cell reselection. The method also includes storing two or more of the frequency layers in an active search list and storing one or more remaining frequency layers in a dormant search list. The method further includes searching for each frequency layer in the active search list. The method still further includes dynamically updating a measurement list, the active search list, and the dormant search list.
Abstract:
A user equipment (UE) may achieve faster cellular redirection, which reduces latency of the redirection, and improves throughput and user perception during redirection. In some instances, the UE may speed up the redirection by determining whether a connection release message with redirection information indicating a target radio access technology (RAT), a target cell and/or a target frequency has been received. The UE modifies a connection release complete procedure when the redirection information is received.
Abstract:
A method of wireless communication includes transmitting a scheduling request through a common channel without performing a random access procedure, when uplink data remains in a buffer and no active grant exists during a call. The method also includes receiving a grant and initiating data transmission through an enhanced channel.
