Abstract: A network, e.g. a New Radio network operating in the unlicensed spectrum, may reserve resources for the purpose of UE(s) performing a random access procedure (RACH) on the network. The network may indicate the resource reservation to the UE(s) in information transmitted to the UE(s) via signaling. The UE(s) may receive the information indicative of the resource reservation and may subsequently perform a RACH using the reserved resources indicated in the information received by the UE(s). The information or at least a portion of the information may be received in an initial signal, in a slot format indicator as part of downlink control information (DCI), in a wideband demodulation reference signal, in a radio network temporary identifier, and/or in radio resource control signaling.

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: This disclosure relates to techniques for physical downlink control channel handling when a secondary cell group is activated in a wireless communication system. A wireless device may establish a wireless link with a master cell group. A secondary cell group may be configured. The wireless device may receive an indication to activate the secondary cell group without performing a random access channel procedure on the secondary cell group. The wireless device may determine quasi-co-located information for a physical downlink control channel of the secondary cell group. The wireless device may perform physical downlink control channel decoding for the physical downlink control channel of the secondary cell group using the determined quasi-co-located information.

Abstract: A user equipment (UE) is configured to operate as a relay UE between a remote UE and a base station. The relay UE receives, from an originating device, a data packet for relay to a recipient device, determines that the relay of the data packet to the recipient device has failed and sends, to the originating device, a transmission including the data packet, wherein the transmission comprises an indication that the data packet is being returned to the originating device.

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: The present application relates to improving coverage and reliability of cellular emergency service. In an example, a relay UE is authorized by a core network to provide a U2N relay for emergency services, where this authorization is based on UE capability information sent to the core network indicating the support of U2N relay emergency functionalities. During a U2N relay discovery, the relay UE indicates, to a remote UE, that this capability can be provided. Accordingly, the remote UE selects the relay UE from a candidate set of relay UEs and a relay communication is established.

Abstract: A wireless user equipment (UE) device may transmit a random access preamble to a base station, using a physical resource on an uplink signal. After failing to receive an initial transmission of a response message from the base station (BS), the UE device may monitor for one or more retransmissions of the response message. Each of the retransmission may include a corresponding transmission number. As an alternative, each of the retransmissions may be at least partially scrambled using a corresponding Radio Network Temporary Identifier (RNTI). As another alternative, a window for monitoring and RNTI calculation may be extended to include the one or more retransmissions. The successive retransmissions may include the same set of UE-specific payloads, or, a decreasing set of payloads over time as UE devices acknowledge successful receipt of their respective payloads.

Abstract: Disclosed are methods and systems to coordinate resource allocation between two UEs for sidelink communication. A receiving UE receiving sidelink communication from a transmitting UE may configure coordination resources used to coordinate sidelink communication between the two UEs. The receiving UE may receive from the transmitting UE data indicating resources reserved and intended to be used by the transmitting UE to transmit sidelink data to the receiving UE. The receiving UE may determine a coordination message used to indicate whether the resources reserved by the transmitting UE are available for use by the receiving UE to receive the sidelink data from the transmitting UE. The receiving UE may determine resources from the coordination resources to be used to carry the coordination message and may transmit the coordination message carried on the selected resources to indicate to the transmitting UE whether to use the reserved resources for the sidelink data.

Abstract: When a user equipment (UE) encounters a radio link failure condition, the UE may transmit a radio link failure report to a network. The report may include information defining the radio link monitoring (RLM) resources of a current RLM configuration. The information may take the form of a resource bitmap or a list of resource identifiers/indices. The network may use the information (and radio resource management measurements) to determine whether the radio link failure occurred due to misconfiguration of RLM resources for the UE. In cases where the network does not provide RLM configuration, the UE may omit the bitmap (or list), or populate the bitmap with all zeros, or populate the bitmap (or list) according to a currently active Transmission Configuration Indication (TCI) state, which is indicated by downlink control information (DCI).

Abstract: A user equipment (UE), next generation NodeB (gNB), or other network component can operate to configure a group configuration message that initiates a plurality of UEs in a coverage area of a non-terrestrial network (NTN) to concurrently transfer communication from a first beam of a first satellite to a second beam of a second satellite. The communications of one or more UEs can be re-directed to the second beam of the second satellite based on downlink control information of the group configuration message.
