Abstract: Certain aspects of the present disclosure provide techniques for defending against false semi-persistent scheduling (SPS) activation detection and/or missed SPS release. According to certain aspects, a user equipment (UE) may detect one or more conditions for a semi-persistent scheduling (SPS) activation or release are met based on a downlink transmission, generate one or more metrics related to downlink transmission, and determine a valid SPS activation or release has occurred if the one or more metrics satisfy one or more criteria. According to certain aspects, a UE may determine a valid semi-persistent scheduling (SPS) activation has occurred, detect a number of PDSCH CRC failures, and implicitly declare an SPS release based on the detection.

Abstract: A method and apparatus for determining available downlink bandwidth are described. The described aspects may include estimating an available link capacity of a cell for a user equipment. The described aspects may include estimating an available fraction of cell resources for the user equipment. The described aspects may include estimating available bandwidth of the cell for the user equipment as a function of the estimated available link capacity and the estimated available fraction of cell resources. Available bandwidth may be estimated for a cell in a Universal Mobile Telecommunications System (UMTS) system when the user equipment is in an idle mode and/or a connected mode. Available bandwidth may be estimated for a cell in a Long Term Evolution (LTE) system when the user equipment is in an idle mode and/or a connected mode.
Abstract translation: 描述了一种用于确定可用下行链路带宽的方法和装置。 所描述的方面可以包括估计用于用户设备的小区的可用链路容量。 所描述的方面可以包括估计用户设备的小区资源的可用分数。 所描述的方面可以包括根据估计的可用链路容量和小区资源的估计可用分数来估计用户设备的小区的可用带宽。 当用户设备处于空闲模式和/或连接模式时，可以为通用移动电信系统（UMTS）系统中的小区估计可用带宽。 当用户设备处于空闲模式和/或连接模式时，可以为长期演进（LTE）系统中的小区估计可用带宽。

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for Channel Quality Indicator (CQI) reporting after resumption of Long Term Evolution (LTE) after a temporary suspension. In certain aspects, in order to minimize performance penalty to LTE on resumption after an LTE tune away for example to service a different Radio Access Technology, information available from before the LTE tune away may be used in addition to one or more additional parameters for determining how to perform LTE CQI calculation/update after tuning back to LTE. In certain aspects, a decision regarding whether a User Equipment (UE) reports a CQI based on channel conditions before the LTE tune away or reports a CQI based on channel conditions after tuning back to LTE may be based on a value of the Doppler estimate, a time duration of the LTE tune away, or a combination thereof.
