Abstract: A device may wirelessly communicate with a number of different cells used in a carrier aggregation. The device may monitor physical downlink control channels (PDCCHs) on the different cells, dynamically switching between a dormant monitoring state (DS) and an active monitoring state (AS). In the DS, the UE may not monitor any PDCCH candidates on the active secondary SCells corresponding to the DS, or it may monitor PDCCH candidates in the search space (SS) set with the largest monitoring periodicity among the multiple SS sets on the active bandwidth part (BWP). In the AS, the UE may monitor a set of PDCCH candidates in physical resources configured by higher layers on the BWPs. Switching from one monitoring state to another may be facilitated through the use of a new downlink control information (DCI) format without data scheduling, a modified existing DCI format with data scheduling, and/or use of a DS timer.

Abstract: Systems and methods disclosed herein use channel state information (CSI) reports from a user equipment (UE) having additional CSI beyond CSI directly derived according to a current MIMO configuration between a base station and the UE. In some embodiments, a channel quality indicator (CQI) according to a selected layer of a plurality of layers used to receive the MIMO transmission as determined relative to the MIMO transmission is reported. In some embodiments, a precoding matrix indicator (PMI) according to a selected layer of a plurality of layers useable to receive rank 1 transmissions is reported along with a CQI determined according to that layer, or according to a layer used to receive the MIMO transmission as determined relative to the MIMO transmission. In some embodiments, a base station configures a UE to report more fulsome CSI according to each of a plurality of ranks.

Abstract: A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for signaling cross-division duplex configurations. One of the methods includes identifying, by a first device and for a first link with a second device, a switch in a first bandwidth part to a second bandwidth part for the first link, the first link associated with a second link having a third bandwidth part; determining, by the first device, whether a bandwidth band between the second bandwidth part and the third bandwidth part satisfies a threshold guard band; and selectively determining to maintain the third bandwidth part for the second link or to switch the third bandwidth part to a fourth bandwidth part for the second link using a result of the determination whether the bandwidth band between the second bandwidth part and the third bandwidth part satisfies the threshold guard band.

Abstract: A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.

Abstract: Apparatuses, systems, and methods for performing uplink transmissions during a dual active protocol stack handover. A wireless device may determine a propagation delay between the wireless device and each of a source cell and a target cell of a dual active protocol stack handover by the wireless device. The wireless device may provide an indication to the source cell of the propagation delay between the wireless device and the source cell, the propagation delay between the wireless device and the target cell, and a propagation delay difference handling capability of the wireless device. The cellular base station that provides the source cell may determine a time division multiplexing pattern for uplink communication for the wireless device during the dual active protocol stack handover based at least in part on the information provided by the wireless device.

Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A serving base station may configure a coverage-limited UE with parameters for the UE to operate in a coverage enhancement mode through RRC signaling, DCI, or RAR grant. The UE may use the configuration parameters to determine whether to enter into the coverage enhancement mode when connecting and communicating with the serving base station. The configuration parameters may configure the UE to exploit both time diversity and frequency diversity to extend and enhance coverage when receiving PDSCH and PDCCH channels. The UE may use the configuration parameters to receive PDSCH and PCCCH that are coverage enhanced using time repetitions and frequency hopping. Advantageously, the base station may flexibly and dynamically configure the UE with coverage enhancement parameters to extend the coverage of the UE using time diversity and frequency diversity gains as the UE moves around.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform downlink control information (DCI) mode signaling and control resource set (CORESET) selection. A DCI mode may be signaled based on a predefined rule, media access control (MAC) control element (CE), and/or group based beam reporting. One or more CORESETs may be selected based on configuration of an active bandwidth part (BWP), CORESET identifier, higher layer index, periodicity, type of search space, and/or MAC CE.
