摘要： While a user equipment (UE) is in a connected mode, the UE may receive only a limited quantity of data. During this phase, a receive diversity configuration may not be enabled, in an effort to conserve power on the UE side. However, in marginal signal conditions and a poor radio environment, downlink performance at the UE side may be enhanced by enabling receive diversity, irrespective of the limited data received by the UE. However, while receive diversity may improve the signal-to-noise ratio (SNR) at the UE end in marginal signal conditions, the UE may also incur a penalty on power consumption. Therefore, certain aspects of the present disclosure provide techniques for dynamically controlling the receive diversity of a wireless device to improve the downlink procedure performance, while minimizing power consumption due to the usage of a second receive chain when in connected mode.

摘要： An apparatus and a method are provided for improving user experience in a multi-radio access bearer (multi-RAB) wireless communication system. After a user equipment establishes a circuit-switched communication link and a packet-switched communication link with a core network, it may receive an indication of an error associated with the packet-switched communication link. Here, if the value of a timer such as the RAB re-establishment timer T314 has a predetermined value (e.g., 0), the user equipment may release the packet-switched communication link, and maintain the circuit-switched communication link. The packet-switched communication link may then be re-established. In this fashion, errors that may occur on the data call need not interrupt a voice call.
摘要翻译：提供了一种用于改善多无线电接入承载（多RAB）无线通信系统中的用户体验的装置和方法。在用户设备建立与核心网络的电路交换通信链路和分组交换通信链路之后，它可以接收与分组交换通信链路相关联的错误的指示。这里，如果诸如RAB重建定时器T314的定时器的值具有预定值（例如，0），则用户设备可以释放分组交换通信链路，并维持电路交换通信链路。然后可以重新建立分组交换通信链路。以这种方式，数据呼叫可能发生的错误不需要中断语音呼叫。

摘要： In an aspect of the present disclosure, presented is a method for wireless communication that includes obtaining at least one transport format combination (TFC), determining a minimum TFC (MinTFC) mode based on at least one TFC state of at least one TFC inside or outside a MinTFC set, and controlling at least one TFC based on the MRAB MinTFC mode. Through this method, pack-switched transmission power can be managed in a manner that will cause a circuit-switched call to function properly in challenging power conditions.

摘要翻译：当用户设备（UE）处于连接模式时，UE可以仅接收有限数量的数据。在该阶段期间，为了节省UE侧的功率，可能不能使能接收分集配置。然而，在边缘信号条件和差的无线电环境中，可以通过启用接收分集来增强UE侧的下行链路性能，而不管UE接收到的有限数据。然而，虽然接收分集可以在边缘信号条件下改善UE端的信噪比（SNR），但是UE也可能对功耗造成惩罚。因此，本公开的某些方面提供了用于动态地控制无线设备的接收分集以提高下行链路过程性能的技术，同时在连接模式时由于第二接收链的使用而使功耗最小化。

摘要： This disclosure provides systems, methods and apparatuses for using a media access control (MAC) control element (CE) for dynamic RLC entities selection. In one aspect, a base station (BS) may generate and transmit the control message to a user equipment (UE) to identify active radio link control (RLC) entities, a primary RLC entity, or other parameters relating to packet data convergence protocol (PDCP) duplication-based communication. In this case, the UE may use the control message to select an RLC entity and may transmit protocol data units (PDUs) to the BS using a data radio bearer (DRB) and the selected RLC entity.

摘要： Information can transfer from a transmitter to a receiver; however, the transmission can consume valuable resources. Therefore, a number of times a transmission is attempted can be tracked and compared against a threshold value. If the transmission occurs too many times—based upon the comparison—then a reset can occur. Tracking can occur for a protocol data unit and/or a control protocol data unit to determine if a reset should occur.

摘要： Systems, devices, and methods for retransmitting protocol data units in wireless communication are provided. In one aspect, a device configured to communicate via a wireless communication link includes a processor. The processor is configured to transmit a plurality of protocol data units (PDUs) to a receiving device, select a first PDU from a set of PDUs that has not been acknowledged by the receiving device, retransmit the first selected PDU with a first poll indicator, select a second PDU from the set, and retransmit the second selected PDU with a second poll indicator. The second PDU is different than the first PDU. In some aspects, the PDUs are selected based on the PDUs' original transmission time. In other aspects, the PDUs may be selected based on the PDU's most recent transmission time.
