Abstract: A user equipment (UE) may reduce reselection delays when the UE is in the idle mode. In such instances, the UE adaptively adjusts a cell reselection timer based at least in part on the availability of a downlink time slot resource. The adjustment of the cell reselection timer may be based at least in part on the availability of the downlink time slot resources. The cell reselection timer is adjusted (e.g., shortened or scaled down) when the downlink time slot resources are unavailable to the UE.

Abstract translation: 当UE处于空闲模式时，用户设备（UE）可以减少重选延迟。 在这种情况下，UE至少部分地基于下行链路时隙资源的可用性自适应地调整小区重选定时器。 小区重选定时器的调整可以至少部分地基于下行链路时隙资源的可用性。 当下行链路时隙资源对UE不可用时，小区重选定时器被调整（例如缩短或缩小）。

Abstract: In certain communication systems, such as TD-HSDPA communications, channel quality index (CQI) reporting is based on a predetermined configuration, such as a mobile device (UE) reporting a CQI for a most recently received data transmission. This configuration may lead to errors if a UE reports a CQI for a certain data transmission but the base station (node B) believes the CQI corresponds to a different data transmission, such as a later transmission the UE never received due to an error processing control channel information. Offered is an indicator to accompany CQI reports. The indicator indicates to the node B which communication resource corresponds to the CQI report.

Abstract: In TDD-LTE wireless systems, an additional fourth preamble for the random access channel, called short RACH, may be used. If short RACH signaling is to be used, the random access preamble is transmitted in the uplink pilot time slot (UpPTS) field in the special subframe. The location of the uplink pilot time slot (UpPTS) is next to a downlink subframe. Therefore, interference from neighbor base stations may interfere with the short RACH preamble within the uplink pilot time slot. The interference to the short RACH will prevent the eNodeB from detecting the short RACH preamble and thus prevent the UE from accessing the network. An interference level on an Uplink Pilot Time Slot (UpPTS) may be measured and when the interference level exceeds a threshold value a User Equipment (UE) is instructed to disable short Random Access Channel (RACH) signaling. The UE may then be instructed to enable normal RACH. When the interference level falls below the threshold value the UE is instructed to resume short RACH signaling

Abstract translation: 在TDD-LTE无线系统中，可以使用称为短RACH的随机接入信道的另外的第四前同步码。 如果要使用短的RACH信令，则在特殊子帧中的上行链路导频时隙（UpPTS）字段中发送随机接入前导码。 上行链路导频时隙（UpPTS）的位置在下行子帧的旁边。 因此，来自相邻基站的干扰可能干扰上行链路导频时隙内的短RACH前导码。 对短RACH的干扰将阻止eNodeB检测短RACH前同步码，从而防止UE接入网络。 可以测量上行链路导频时隙（UpPTS）上的干扰电平，并且当干扰电平超过阈值时，指示用户设备（UE）禁用短随机接入信道（RACH）信令。 然后可以指示UE启用正常的RACH。 当干扰电平低于阈值时，UE被指示恢复短的RACH信令

Abstract: A user equipment (UE) capable of communication with multiple radio access technologies (RATs) may receive offset timing information from a cell of a RAT. The offset timing information indicates the timing offset between a communication frame of one RAT relative to a communication frame of another RAT. The UE may use the timing offset information to more accurately identify desired portions of a signal of a non-connected RAT, thereby improving inter-RAT signal measurement and mobility.
