Abstract: Various examples and schemes pertaining machine-to-machine (M2M) semi-persistent scheduling (SPS) in wireless communications are described. A user equipment (UE) receives a control signal from a network node of a wireless network. The UE applies, based on the control signal, an SPS configuration such that the UE enters one of one or more low-power modes between two adjacent SPS occasions.

Abstract: Various examples and schemes pertaining to conditional radio resource control (RRC) confirm messaging are described. A user equipment (UE) communicates with a network node of a wireless network. In communicating with the network node, the UE transmits a first message to the network node and receives a second message from the network node responsive to the transmitting of the first message. The UE also determines whether to transmit a third message to the network node acknowledging receipt of the second message. That is, transmission of the third message as a confirmation of receipt of the second message is conditional or otherwise optional so as to reduce signaling overhead.

Abstract: Various examples and schemes pertaining to uplink (UL) transmission timing for non-terrestrial networking (NTN) are described. An apparatus receives, from a network, downlink control information (DCI) indicating an NTN offset for a scheduling delay. Accordingly, the apparatus performs one or more UL transmissions to a satellite with the scheduling delay which accounts for the

Abstract: A method of high reliability and early data transmission (EDT) is proposed. EDT allows one uplink transmission (optionally) followed by one downlink data transmission during a random-access channel (RACH) procedure, which can reduce the signaling overhead and save UE power. To improve reliability, for uplink EDT, there would be different set of RACH reattempt parameters in the UE for different types of access. For downlink EDT, there would be an indication in the paging message to trigger whether the UE would use legacy RACH or not. Further, the configuration for PRACH resource for EDT can be independent to legacy PRACH resource configuration. Under certain conditions, UE can fallback to legacy RACH procedure for high reliability.

Abstract: Various examples and schemes pertaining to differentiation of user equipment (UE) in narrowband IoT (NB-IoT) are described. A processor of a UE generates a signal containing UE-specific information that is specific to the UE. The processor transmits the signal to a network node of a wireless network. The processor then receives a response from the network node, the response comprising an access stratum (AS) configuration created by the network node based on the UE-specific information. The processor also applies the AS configuration which reduces power consumption of the UE.

Abstract: Various examples and schemes pertaining to narrowband reference signal (NRS) transmission on non-anchor carriers in narrowband IoT (NB-IoT) are described. A wireless network indicates a subset of one or more paging groups of user equipment (UEs) among a plurality of UEs in an NB-IoT cell. The wireless network then transmits one or more narrowband reference signals (NRSs) in one or more paging frames or one or more paging occasions associated with the subset of one or more paging groups.

Abstract: Various examples and schemes pertaining to utilization of assistance information for compensation for Doppler shift in non-terrestrial networks (NTNs) are described. A user equipment (UE) receives assistance information via an access link from a network node of an NTN such as a satellite or an unmanned aircraft system (UAS) platform. The UE then performs an operation with respect to communications with the network node based on the assistance information such as cell re-selection or beam switching.

Abstract: Various examples and schemes pertaining to enhancement of sounding reference signal (SRS) in mobile communications are described. An apparatus determines to activate one from an SRS configuration set that includes an SRS configuration and at least one enhanced SRS configuration. The apparatus then transmits an SRS to a network node of a wireless network based on activated one from the SRS configuration set.

Abstract: Various examples and schemes pertaining to NB-IoT physical random access channel (PRACH) resource partitioning and multiple grants in random access response (RAR) for early data transmission (EDT are described. A network node schedules multiple grants for EDT during a random access (RA) procedure with a user equipment (UE). The network node transmits to the UE a message indicating the multiple grants mapped to a maximum broadcast transport block size (TBS) configured for each of one or more preamble resource of a plurality of preamble resources. The UE calculates a TBS that fits an uplink (UL) data packet of the UE. The UE selects one or more PRACH resources for EDT for the TBS based on a wireless communication coverage of the UE by the network node. The UE transmits to the network node in the RA procedure a first message (Msg1) indicating the selected one or more PRACH resources.
