Abstract: A method of wireless communication with a multi subscriber identity module (SIM) multi standby UE includes tuning away from a data call on a first SIM to perform an activity for a second SIM. The method also includes tuning back to the data call on the first SIM and delaying, for a predetermined time period, a layer 2 message after tuning back. The layer 2 message can be a protocol data unit (PDU) status transmission in response to receiving a polling bit, a radio link control (RLC) protocol data unit (PDU) polling bit transmission, or a data re-transmission.

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 translation: 用户设备（UE）并行而不是串行地发送诸如物理随机接入信道（PRACH）和随机接入上行链路控制信道（E-RUCCH）的信道的随机接入请求和调度请求以提高数据传输等待时间。 在一种情况下，响应于接收到硬切换命令，UE发送用于随机接入过程的第一前同步码和用于调度请求的第二前同步码。 UE向前导码之一接收第一确认响应。 UE至少部分地基于哪个前导码被确认来确定何时发送调度请求。

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 translation: 用户设备（UE）可以在等待完成接力切换过程的同时调整其与目标小区的上行链路传输功率和定时。 上行链路发送功率/定时的调整量可以基于宣告接力棒切换失败之前剩余的时间量。 调整的步长可以随着切换失败之前的剩余时间变小而增加。

Abstract: When a user equipment is performing a packet-switched handover from a source radio access technology (RAT) to target RAT (such as Long Term Evolution) in connected mode, the UE may indicate a UTRA RAT capability based on an operator of the source RAT or an operator of the target RAT. If the operator is associated with a TD-SCDMA network, the UE may indicate a TD-SCDMA capability. If the operator is not associated with a TD-SCDMA network, the UE may indicate a W-CDMA capability.

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: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.
