Abstract: A user equipment (UE) reduces random access procedure delays when reselecting or redirecting from a cell of a first radio access technology (RAT) by preventing a persistence check before initiating the random access procedure. In one instance, the UE prevents the persistence check by preventing collection of system information including a scaling factor used for the persistence check before initiating the random access procedure.

Abstract: A user equipment (UE) applies an uplink timing adjustment during a high speed data call to allow uplink transmission of different UEs to arrive at a base station at a particular estimated time. In one instance, the UE determines whether a downlink (DL) timing varies more than a predetermined amount within a specified time period. The UE applies a timing advance command received in response to a scheduling request when the timing varies more than the predetermined amount. The UE also ignores a current uplink timing based on a closed loop timing advance command

Abstract: A user equipment (UE) sends random access request and scheduling requests for channels, such as a physical random access channel (PRACH) and a random access uplink control channel (E-RUCCH), in parallel rather than serially to improve data transmission latency. In one instance, the UE transmits a first preamble for a random access procedure and a second preamble for a scheduling request in response to receiving a hard-handover command. The UE receives a first acknowledgment response to one of the preambles. The UE determines when to transmit the scheduling request based at least in part on which preamble is acknowledged.

Abstract: In baton handover in TD-SCDMA communications, a user equipment (UE) may use of a single receiver to reduce call drops during baton handover. Following uplink handover, the UE may simultaneously receive downlink communication from a target cell and a source cell when a condition is satisfied. If the UE measures a signal quality of the downlink communication of the target cell greater than a signal quality of the downlink communication of the source cell, the UE switches to the target cell and completes the handover. If the UE measures a signal quality of the downlink communication of the source cell greater than a signal quality of the downlink communication of the target cell, the UE returns the uplink to the source cell and terminates the handover. Thus the UE may avoid handover to a target cell with poor signal quality.

Abstract translation: 在TD-SCDMA通信中的接力切换中，用户设备（UE）可以使用单个接收机来减少接力切换期间的呼叫丢弃。 在上行链路切换之后，当满足条件时，UE可以同时从目标小区和源小区接收下行链路通信。 如果UE测量目标小区的下行链路通信的信号质量大于源小区的下行链路通信的信号质量，则UE切换到目标小区并完成切换。 如果UE测量源小区的下行链路通信的信号质量大于目标小区的下行链路通信的信号质量，则UE返回到源小区的上行链路并终止切换。 因此，UE可以避免切换到信号质量差的目标小区。

Abstract: A user equipment (UE) may adjust its uplink transmission power and timing for communications with a target cell while awaiting completion of a baton handover procedure. The amount of adjustments for the uplink transmission power/timing may be based on an amount of time remaining before baton handover failure is declared. The steps size of the adjustments may increase as the time remaining before handover failure becomes smaller.

Abstract: A method of wireless communication includes modifying an initial transmit power for a subsequent uplink physical channel based on the difference between the desired received powers of the subsequent uplink physical channel and a random access physical channel. When the difference between the desired power of the subsequent uplink physical channel and the random access physical channel is above a predefined threshold, the modification is based on a first adjusted factor. When the subsequent uplink physical channel and random access physical channel are on different frequencies (or time slots) the modification is based on a second adjusted factor.

Abstract: Methods, systems, and devices are described for concurrently performing handoff-related measurements for neighbor cells using multiple input multiple output (MIMO) antenna resources. In one example, a mobile device is in communication with a serving cell. Handoff-related measurements of first wireless signals from a first neighbor cell are performed. The first wireless signals are received at first MIMO antenna resources of a device. Handoff-related measurements of second wireless signals from a second neighbor cell are performed, as well. The second wireless signals are received at second MIMO antenna resources concurrently with the first wireless signals received at the first MIMO antenna resources. The first handoff-related measurements and the second handoff-related measurements may be performed during a scan interval. A type of handoff-related measurement to perform may be determined based on a determined length of the scan interval.

Abstract: In a method of wireless communication, a grant allocating a plurality of high speed subframes for high speed data channels is received before a measurement gap for tuning away from a serving radio access technology (RAT). At least one high speed subframe is allocated in the grant falling within the measurement gap. High speed data is processed only on high speed subframes of the plurality of high speed subframes before and after the measurement gap. An acknowledgement/negative acknowledgement (ACK/NACK) feedback is transmitting and only the high speed subframes of the plurality of high speed subframes before and after the measurement gap are considered.

Abstract: A user equipment (UE) determines which neighbor cell frequencies and radio access technologies (RATs) to measure based on the UE's recorded history of measurement results and searches. In one instance, the UE determines a set of neighbor cells for each of multiple serving cells. The UE records measurement results and search history for each of the set of neighbor cells, and the corresponding multiple serving cells. In another instance, the UE determines a measurement schedule for neighbor cells, including neighbor RATs and/or frequencies, based on the recorded measurement results, search history and the current serving cell.

Abstract: A user equipment (UE) transmits measurement reports, and postpones the transmission of a measurement report when a neighbor cell signal strength is greater than the signal strength of the target cell(s). In one instance, the UE identifies a target cell having the strongest signal strength. In another instance, the UE postpones a transmission of a measurement report for a target cell when a neighbor cell signal strength is greater than the strongest target cell signal strength and the strongest target cell signal strength is below an absolute threshold value.
