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 adjusts an absolute inter radio access technology (IRAT) handover threshold for a target radio access technology (RAT). The adjustment occurs when a serving cell signal strength is below a threshold for a serving RAT and the target RAT is successfully acquired during IRAT measurement.
Abstract:
A method of wireless communication enables an inter-radio access technology (IRAT) neighbor cell measurement when a serving RAT signal strength is continuously below a first threshold value for a first length of time. The method also disables the IRAT neighbor cell measurement when the serving RAT signal strength is continuously above a second threshold value for a second length of time.
Abstract:
A method of wireless communication includes adaptively modifying a measurement schedule order for a current discontinuous reception cycle. The method also includes receiving system information for two or more cells. The measurement schedule order is based on a priority of a cell associated with a radio access technology, a frequency, or a combination thereof.
Abstract:
A user equipment (UE) may perform an inter radio access technology (IRAT) measurement in time slots not deemed to be carrying critical data. In such instances, the UE only transmits and decodes critical data in the critical time slots when a serving cell signal is low for a determined period of time. Otherwise, when the time slots do not carry critical data, i.e., non-critical time slots, the UE stops transmitting and decoding and uses the non-critical time slots for IRAT measurement.
Abstract:
A measurement reporting method to avoid strong interference includes measuring all cells on a neighbor frequency indicated by a network on a neighbor list. A first and second set of cells are identified. The identified first set of cells are from the neighbor list and have a first signal strength a first predefined amount above a serving cell signal strength. The second set of cells are not on the neighbor list and have a second signal strength above a first threshold signal value. The first signal strength of the first set of cells and the second signal strength of the second set of cells are compared to determine whether to send a measurement report for the first set of cells.
Abstract:
A user equipment (UE) is configured to maintain an updated frequency list for pseudo-fast return handover. The UE receives a frequency list for pseudo fast return when the UE is in an idle mode in a first radio access technology (RAT). When the UE is in a connected mode in a second RAT, the list is updated based on actual UE inter- and intra-frequency measurements of the first RAT during mobility.
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 measurement reporting method includes measuring a first signal from a first neighbor base station until a first timer expires. Also measured is a second signal from a second neighbor base station until a second timer expires. The first signal is compared with the second signal. A measurement report of the first signal is delayed when the second signal is better than the first signal and the first timer expires prior to the second timer.
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.
