Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may detect a high speed mobility condition and a directionality of movement based on signal measurements, such as location or Doppler measurements. The UE may adjust a measurement reporting process (e.g., a time-to-trigger (TTT) parameter, a signal quality metric, a measurement reporting delay, etc.) based on the high speed mobility condition and the directionality of movement. If the UE detects the high speed mobility condition, the UE may add the physical cell identifier (PCI) of the serving cell to a list of recent serving cells. If a neighboring cell is also on the list of recent serving cells, the UE may adjust a measurement reporting process, which may affect whether the UE is directed to perform handover to the neighboring cell based on whether the neighboring cell is on the list of recent serving cells or not.

Abstract: A user equipment (UE) prevents re-transmissions of downlink high-speed data during a tune away procedure when an acknowledgment (ACK) to the high-speed data is not received at a network. In one instance, the UE decodes a first high-speed grant and corresponding downlink high-speed data before tuning away from a serving base station. The UE determines that a first timing for transmitting an acknowledgement of the decoded high-speed downlink data occurs during a tune away gap. The UE determines a second time for sending the acknowledgment based on a determination of a second high-speed grant missed during the tune away gap. The UE transmits an acknowledgement (ACK) for the decoded downlink high-speed data in accordance with a time line of the missed second high-speed grant.

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 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 translation: 用户设备（UE）可以在不被认为携带关键数据的时隙中执行互无线接入技术（IRAT）测量。 在这种情况下，当服务小区信号在确定的时间段内为低时，UE仅在关键时隙中发送和解码关键数据。 否则，当时隙不携带关键数据，即非关键时隙时，UE停止发送和解码，并将非关键时隙用于IRAT测量。

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.
