Abstract: A base station may transmit to a device an indication of codebook subset restriction (CBSR), which includes at least a restriction on a frequency basis. The device may receive the indication of CBSR, and may transmit to the base station channel state information (CSI) according to the received indication of CBSR. The indication of CBSR may also include a restriction on a spatial basis and restrict the device from reporting the CSI based on a subset of the frequency basis in addition to the spatial basis per configuration of the base station. The indication of CBSR may include a separately configured maximum allowed amplitude of a weighting coefficient for the spatial basis and the frequency basis, where the weighting coefficient is associated with a column vector of a precoding matrix used by the base station and the device. The number of frequency bases and the frequency compression units may be determined based on a number of different criteria, for example the number of antennas, the number of subbands, etc.

Abstract: A wireless communication device (UE) may provide information pertaining to one or more operating capabilities of the UE to LTE and 5G-NR networks. The UE may transmit information to an LTE base station directly, and to a 5G-NR base station directly, or indirectly via the LTE base station. The information may include preferred values corresponding to any number of different operating parameters associated with wireless communications or wireless communication capabilities of the UE in both LTE and 5G-NR networks, to inform and/or request the LTE and 5G-NR networks to make provisions based on the transmitted information for the wireless communications of the UE on those networks. The UE may thereby provide assistance information to LTE and 5G-NR networks in a multi-radio-access-technology dual-connectivity setting to request the respective networks to adjust certain operating capabilities of the UE in order to alleviate one or more operating issues that may be affecting the UE.

Abstract: Apparatuses, systems, and methods for performing downlink signal reception with antenna panel switching in a wireless communication system. A cellular base station may receive an indication of an antenna panel activation delay from a wireless device. The cellular base station may select a scheduling offset for a transmission to the wireless device based at least in part on the antenna panel activation delay. The scheduling offset may be selected to be at least the length of the antenna panel activation delay if it is expected that the wireless device may perform antenna panel activation to receive the transmission. The cellular base station may schedule the transmission to the wireless device using the selected scheduling offset, and may perform the transmission to the wireless device at the selected scheduling offset after scheduling the transmission to the wireless device.

Abstract: Apparatuses, systems, and methods to dynamically indicate preference for self-contained slots and slot duration by a user equipment device (UE) in communication with a base station (e.g., a gNB) using a 5G NR radio access technology. A UE may determine to send an indication to a gNB indicating a preference for self-contained slots and slot duration for downlink and/or uplink communications utilizing one or more of the physical downlink control channel (PDCCH), the physical downlink shared channel (PDSCH), and/or acknowledgement messaging (ACK/NACK) for downlink communications, and utilizing one or more of the physical uplink control channel (PUCCH), the PDCCH, and/or the physical uplink shared channel (PUSCH) for uplink communications. The configuration of self-contained slots and slot duration for uplink and/or downlink may be based on one or more of average packet size, average packet rate, traffic type and UE processing capabilities.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for configuring a power savings signal in fifth generation (5G) new radio (NR) networks. The wireless device may transmit, to a base station within a network, power savings requirements and receiving, from the base station, a configuration of a power saving signal, where the configuration indicates one or more functionalities of the power saving signal. The wireless device may periodically receive, from the base station, the power saving signal and interpret the power saving signal based on the configuration. The configuration of the power saving signal may be received via radio resource control signaling.

Abstract: An example method for wireless communication includes: transmitting by a base station, to a user device in a reduced power state, resource information for receiving a channel state information reference signal (CSI-RS) and tracking reference signal (TRS); transmitting the CSI-RS and TRS based on the transmitted resource information to the user device, wherein the user device has exited the reduced power state; determining whether there is paging information to transmit in a first physical downlink shared channel (PDSCH) transmission for the user device; transmitting a downlink control information message, wherein the downlink control information message is based on the determination that there is paging information for the user device, and wherein the user device has synchronized with the base station; and transmitting the first PDSCH transmission, based on the determination that there is paging information for the user device.

Abstract: Methods, systems, and devices for wireless communications are described. SSB based inter-frequency measurements may include configuring a UE to perform inter-frequency measurements without measurement gap within a measurement window, and applying scheduling restrictions to prioritize the inter-frequency measurements over uplink transmissions within the measurement window. The measurement window includes an SMTC window duration. Measurement resource sharing or restriction is described for SSB based inter-frequency measurement objects without measurement gap.

Abstract: Techniques discussed herein can facilitate successful decoding of Physical Downlink Shared Channel (PDSCH) based on a reduced number of retransmissions. Based on a given PDSCH, embodiments discussed herein can communicate feedback (e.g., Hybrid Automatic Repeat reQuest (HARQ) feedback, Channel State Information (CSI) feedback) that indicates an amount of additional information that can allow a User Equipment (UE) to successfully decode the PDSCH. In some embodiments, the feedback can indicate a requested Redundancy Version (RV) sequence that can allow the UE to successfully decode the PDSCH. In other embodiments, the feedback can indicate the amount of additional information, based on which a receiving Base Station (BS) can select a RV sequence.

Abstract: This disclosure relates to performing cellular communication using a control information monitoring framework. A wireless device may monitor a control channel for control information according to a first periodic pattern. According to the first periodic pattern, the wireless device may monitor the control channel in a specified slot during each period of the first periodic pattern. Each period of the first periodic pattern may include multiple slots. The wireless device may receive control information during a first slot. The first slot may be a specified slot according to the first periodic pattern. The control information received during the first slot may schedule a data communication. The wireless device may monitor the control channel for control information in at least one slot that is not specified according to the first periodic pattern based at least in part on receiving control information during a specified slot according to the first periodic pattern.

Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.
