Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.

Abstract: Methods, apparatuses, and systems are disclosed for providing traffic information pertaining to a data traffic group, e.g., for use in 3GPP XR communications. A UE may transmit a traffic flow including data of a certain type (e.g., video, audio, control/pose) generated by an application implemented on the UE, such as an augmented reality application. The traffic flow may include bursts of data traffic groups, wherein each group includes a plurality of data packets containing a functional set of data, such as data for encoding a single video frame. A UE may generate and transmit, to a base station, traffic information regarding the nature, status, performance, and/or constraints of the data traffic group. The base station may use the traffic information to make intelligent scheduling decisions regarding the data traffic group.

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 smart repeater (SMR) can be configured to amplify and forward data from a base station based on received control information for managing power efficiency of on-off operations. The SMR can configure a power control mechanism based on the control information to adapt one or more bandwidths associated with the SMR based on the control information to save power and forward the communications to the base station or the UE. The control information can include a component carrier (CC) index or a bandwidth part (BWP) identifier (ID), and a set of parameters to configure on-off operations of the one or more bandwidths according to one or more CCs or BWPs.

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: Methods, apparatuses, and systems are disclosed for enhancing timing relationships in non-terrestrial networks (NTNs), e.g., by managing timing offset values and intelligently handling reporting failure relating to timing information reporting. To accommodate increased propagation delay in NTNs, a user equipment (UE) may supplement its timing advance (TA) value with component values representing roundtrip times to the satellite. The UE may maintain both open-loop and closed-loop portions of the TA value, and may report the TA value, or components thereof, to the network for timing synchronization. Methods and systems are also disclosed for failure handling in this reporting process.

Abstract: Apparatuses, systems, and methods for enhancing non-PMI based CSI reporting for NC-JT in multi-TRP operations, including addressing channel CRI reporting, CQI reporting, RI reporting, and CSI processing complexity and timeline in NC-JT multi-TRP operations. For example, a UE may receive, from a base station, a configuration for a first set of CSI-RS resources for a first TRP (associated with single TRP operation), a second set of CSI-RS resources for a second TRP (associated with single TRP operation), and a third set of pairs of CSI-RS resources for the first TRP and second TRP (associated with multi-TRP operation). The UE may report, to the base station, a CRI report indicating whether the UE prefers single TRP operation from the first TRP or the second TRP, or multi-TRP operation from the first TRP and the second TRP. The CRI report may be based on the configuration.
