Abstract: A user equipment (UE) includes first and second subscriber identity modules (SIMs), possibly subscribed to different carriers. When the first SIM is in a connected state and the second SIM is in an idle state, the UE may need to periodically tune away a radio from a first frequency used for communication under the first SIM to a second frequency used for idle mode activity under the second SIM. The UE may provide to the network of the first SIM the second SIMs traffic activity pattern and/or serving frequency so that the network may provide coordinated configuration and/or scheduling for the UE device, e.g., in order to make the action of tuning away (and tuning back) the radio more efficient and/or to decrease the network impact of such radio tune aways (e.g., to decrease wasted uplink scheduling and wasted downlink transmissions for the first SIM).

Abstract: Systems, apparatuses, and methods for performing cellular relay for an accessory device. A relay device may establish cellular communication with a base station and an accessory device. Establishing communication with the accessory device includes establishing synchronization with the accessory device using a cellular sidelink synchronization channel and a cellular broadcast channel. Establishing communication with the accessory device includes configuring resources for performing communication with the accessory device. Establishing communication with the accessory device includes indicating the resources to the accessory device. The relay device may relay information between the base station and the accessory device using the resources.

Abstract: A base station and wireless communication (UE) may perform type II CSI-RS port selection based at least on partial reciprocity between an uplink path and a downlink path between the base station and the UE. The base station may identify dominant signal paths between the base station and the UE, based on measurements performed during uplink transmissions, and may transmit, to the UE, corresponding information indicative of CSI measurement and reporting configuration that may include a single measurement resource or multiple measurement resources. Each measurement resource may include multiple-port CSI-RS ports. The UE may indicate, to the base station, selection of a measurement resource when multiple measurement resources are configured, and may also report layer independent or layer common selection of a subset of CSI-RS ports included in the indicated single measurement resource or multiple measurement resources. Further enhancements include frequency domain compression enhancement and dynamic codebook parameter reconfiguration.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to communicate an RRC message (such as an RRC configuration message) having a size that exceeds PDCP SDU size constraints. According to some embodiments, a base station may generate a large RRC message, e.g., by encoding an RRC configuration as a single large RRC message. The base station may then segment the RRC message, e.g., at the RRC layer or the PDCP layer, into a series of PDUs that comply with the size constraints. According to some embodiments, the base station may encode an RRC configuration as a series of RRC messages, each complying with the size constraints. The base station may further provide an indication of when a receiving user equipment should apply the RRC configuration.

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: Techniques to protect subscriber identity in messages communicated between a user equipment (UE) and a cellular wireless network entity by using multiple ephemeral asymmetric keys are disclosed. The UE determines multiple ephemeral UE public and secret key pairs, while the cellular wireless network entity provides a network public key to the UE. The network public key may be updated over time. Multiple encryption keys based on the multiple ephemeral UE secret keys and the public network key are derived and used to encrypt a subscription permanent identifier (SUPI) to generate multiple subscription concealed identifiers (SUCIs). Each SUCI is used only once for messages communicated to a cellular wireless network and discarded after use. New SUCI are generated when the network public key is updated.

Abstract: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.

Abstract: Described herein are apparatuses, systems and methods for enhancing short message service (“SMS”) over Internet protocol (“IP”). The methods including at, a user equipment (“UE”) connected to a network, receiving an indication from the network, wherein the indication identifies whether the network supports an SMS over IP session, when the indication identifies that the network supports the SMS over IP session, registering the UE for voice communication and the SMS over IP session with the network, and when the indication identifies that the network does not support the SMS over IP session, registering the UE for voice communication without the SMS over IP session with the network.
