Abstract: Embodiments of a User Equipment (UE) and methods of communication are generally described herein. The UE may, if a regular buffer status report (BSR) is triggered and a logical channel scheduling request (SR) delay timer is not running, and if available uplink shared channel (UL-SCH) data resources do not meet one or more logical channel prioritization (LCP) mapping restrictions configured for a logical channel of uplink data: trigger a scheduling request to request UL-SCH data resources for a new transmission of uplink data. Currently pending SRs and BSRs may not be cancelled after assembly of a medium access control (MAC) protocol data unit (PDU), but may be cancelled at a later time when a MAC PDU including a BSR is transmitted.

Abstract: This disclosure describes methods, systems, and devices for mobile terminated (MT) early data transmission (EDT). In one example, a method involves receiving, by a node of the RAN, an MT EDT indication and information indicative of downlink data for transmission to a user equipment (UE) served by the RAN. The method further involves based on the information indicative of the downlink data, determining to initiate MT EDT to transmit the downlink data to the UE. The method also involves generating a Radio Resource Control (RRC) paging message comprising: (i) the MT EDT indication, (ii) an indication of a contention free (CF) physical random access channel (PRACH) resource, and (iii) an indication of an EDT-radio network temporary identifier (EDT-RNTI). Further, the method involves transmitting the RRC paging message to the UE.

Abstract: One or more methods for enhancing inter-node handover (HO) signaling for conditional HO (CHO). At least one of the methods include: providing a message that comprises indications of a plurality of potential target cell identifiers that are applicable to a CHO operation; and performing a CHO operation based on the message.

Abstract: Systems and methods of early termination of uplink data transmissions for a UE are described. The UE transmits capacity information that indicates that the UE supports use of an ETS. The ETS indicates successful reception by the eNB of the uplink data prior to an end of a scheduled transmission period to transmit repeated instances of the data. The UE receives a schedule for repeated transmissions of the data that is based on a coverage level of the UE, and then transmits sets of one or more repetitions. After the transmission, the UE monitors a predetermined resource whether the ETS is present or whether the ETS indicates an ACK. If the ETS indicates successful reception, the UE terminates transmission of the remaining repetitions of the data and enters a sleep mode or transmits other uplink data.

Abstract: A UE in idle mode may use a preconfigured uplink resource for transmission, retransmission, and/or HARQ. For example, the UE may store configuration data for a preconfigured uplink resource and an RNTI for idle mode communication. In idle mode, the UE generates an uplink transmission using the preconfigured uplink resource. After the uplink transmission, the UE starts a retransmission timer, and monitors PDCCH with the RNTI provided in the configuration data for HARQ ACK/NACK.

Abstract: Technology for an Integrated Access and Backhaul (IAB) node in an IAB network is disclosed. The IAB node can decode, at a distributed unit (DU) of the IAB node, a first resource request received from one of a user equipment (UE) or a child IAB node, wherein the first resource request is associated with the UE. The IAB node can encode, at a mobile terminal (MT) of the IAB node, a second resource request for transmission to the parent IAB node or the IAB donor triggered by receipt of the first resource request, wherein the second resource request is transmitted prior to a receipt of a protocol data unit (PDU) at the DU of the IAB node.

Abstract: A telecommunication network may operate to enable a wake up signals (WUSs) within the telecommunication network. A mobility management entity (MME) may estimate a coverage enhancement (CE) level of a user equipment (UE), determine, based on the CE level, a number of repetitions for a wake up signal (WUS) for the UE, and cause a WUS for UE to be transmitted to a radio access network (RAN) node corresponding to the UE. The RAN node may inform the MME that the RAN node has disabled the WUS feature, and may cause system information to be broadcast to UEs in IDLE mode, indicating that the WUS feature of the RAN node has been disabled. A UE may determine a paging occasion (PO) determine a maximum WUS duration, minimum offset, and start location of the WUS.

Abstract: Technology for a user equipment (UE) operable to perform downlink (DL) channel quality measurement reporting is disclosed. The UE can decode a system information block type y bandwidth reduced (SIBy-BR) received from an eNodeB. The SIB1-BR can instruct the UE to include a DL channel quality measurement report in a message 3 (Msg3) transmitted during a random access procedure between the UE and the eNodeB, wherein y is a positive integer greater than or equal to 1. The UE can determine a DL channel quality measurement for a DL channel between the UE and the eNodeB. The UE can encode the Msg3 for delivery over an uplink channel to the eNodeB. The Msg3 can be delivered during the random access procedure and can include the DL channel quality measurement report with the DL channel quality measurement.
