Abstract: A wireless communication device (UE) may reliably decode control information during wireless cellular communications. The UE may decode the Physical Control Format Indicator Channel (PCFICH) for a given wireless network, and if the decode is unsuccessful, the UE may perform a blind decode of the PCFICH. The UE may decode, for the network, a Physical Downlink Control Channel (PDCCH) for a current subframe using a specified control format indicator (CFI) value. If the decode of the PDCCH is successful, the UE may communicate over the NW, using the specified CFI value. If the decode for the current subframe is unsuccessful, the UE may decode the PDCCH for a different next subframe using a different CFI value until the PDCCH for the NW has been successfully decoded. The CFI value may be specified based at least on common signaling present in certain subframes received by the UE.

Abstract translation: 无线通信设备（UE）可以在无线蜂窝通信期间可靠地解码控制信息。 UE可以解码用于给定无线网络的物理控制格式指示符信道（PCFICH），并且如果解码不成功，则UE可以执行PCFICH的盲解码。 UE可以使用指定的控制格式指示符（CFI）值为网络解码当前子帧的物理下行链路控制信道（PDCCH）。 如果PDCCH的解码成功，则UE可以使用指定的CFI值通过NW进行通信。 如果当前子帧的解码不成功，则UE可以使用不同的CFI值对不同下一个子帧的PDCCH进行解码，直到NW的PDCCH已被成功解码。 可以至少基于由UE接收的某些子帧中存在的公共信令来指定CFI值。

Abstract: Various mechanisms for paging link-budget-limited (LBL) devices are disclosed, including: (1) transmitting paging message with non-conventional paging identifier; (2) transmitting paging message(s) with increased power; (3) repeating transmission of paging message to support combining at receiver. Various mechanisms for UE device to signal LBL status are disclosed, including, transmitting status flag or special value of DRX cycle to network node as part of tracking area update and/or attach request. The network node informs a base station of the device's LBL status as part of a paging message. (The network node may, e.g., assign an S-RNTI to the LBL device from a reserved subset of S-RNTI space.) The base station invokes a paging enhancement mechanism when paging an LBL device. Alternatively, the base station may page UE devices without knowledge of LBL status, e.g., by counting paging attempts for a given UE, and boosting power after the Nth paging attempt.

Abstract: A user equipment (UE) is configured to perform rate matching for reference signals under certain conditions. The UE receives information associated with a downlink reference signal for a first radio access technology (RAT), wherein the first RAT is different than a currently camped second RAT, identifies reference signal occasions for the downlink reference signal and receives downlink control information from the second RAT via a physical downlink control channel (PDCCH).

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for determining resources for scheduling side-link communications. The resources may be semi-persistent and/or dynamic resources. A user equipment device (UE) may determine a resource map for use in scheduling semi-persistent resources for side-link communications with at least one wireless node. The UE may transmit a resource map request message indicating preferred resource blocks, where each resource block may be defined by a time and a frequency. The UE may receive a confirmation message that may include a report regarding a set of resource blocks. The set of resource blocks may be from the preferred resource blocks included in the resource map request message. The UE may determine, based, at least in part, on the confirmation message, resource blocks to be used for the side-link communications and initiate the side-link communications using the determined resource blocks.

Abstract: Apparatuses, systems, and methods for a base station to perform a method construct dynamic hierarchical sub-configurations of bandwidth parts (BWPs) for use in a connected mode discontinuous reception (CDRX) communication session with a user equipment (UE) device. The base station may configure a first BWP at a baseband frequency associated with the CDRX communication session as a default BWP, a second BWP with a wider bandwidth than the first BWP as a transmission BWP, and one or more third BWPs as resting BWPs. The transmission BWP and the one or more resting BWPs may be configured to periodically override the default BWP as the active BWP for a predetermined number of CDRX cycles. The transmission BWP may be utilized, when activated to perform data transmission by UE device, and the one or more resting BWPs may be utilized, when activated, for performing channel measurements.

Abstract: Systems and methods are provided for a user equipment (UE) to perform frequency offset (FO) delta tracking. For an anchor component carrier (CC), the UE wakes up to perform tracking updates on a plurality of successive DRX cycles. For the non-anchor CC, the UE determines a minimum update interval Δtupd, and schedules wake-ups on a first subset of the plurality of successive DRX cycles based on the minimum update interval Δtupd. For the first subset of the plurality of successive DRX cycles with scheduled wake-ups, the UE performs the tracking updates on the non-anchor CC and updates an FO delta between the anchor CC and the non-anchor CC. For a second subset of the plurality of successive DRX cycles without the scheduled wake-ups on the non-anchor CC, the UE applies the FO delta to correct for a frequency error.
