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: Methods and apparatus are provided contention based uplink data transmission. In one novel aspect, the contention-based uplink data channel is used to transmit the data directly to the network. In one embodiment, the UE selects an UL data channel from a set of preconfigured uplink contention based data channels and sends the UL data transmission on the selected UL data channel. In one embodiment, the contention based UL data has a narrow bandwidth with a long CP such that the TA is not needed from the base station. In another embodiment, a small signaling payload is included in the CB UL data transmission if the size of the data contents cannot be fit in the UL data channel. In one embodiment, the signaling payload is the BSR. The UE, subsequently, receives an UL grant and sends the remaining data contents using the allocated data channel in the UL grant.
Abstract translation: 提供了基于争用的上行链路数据传输的方法和装置。 在一个新颖的方面，基于争用的上行链路数据信道被用于将数据直接发送到网络。 在一个实施例中，UE从一组预先配置的基于上行链路竞争的数据信道中选择UL数据信道，并在所选择的UL数据信道上发送UL数据传输。 在一个实施例中，基于争用的UL数据具有具有长CP的窄带宽，使得不需要来自基站的TA。 在另一个实施例中，如果数据内容的大小不能适应于UL数据信道，那么在CB UL数据传输中包括小的信令有效载荷。 在一个实施例中，信令有效载荷是BSR。 随后，UE接收UL许可，并且在UL授权中使用所分配的数据信道发送剩余的数据内容。

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 NTN offset.

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.

Abstract: Various examples and schemes pertaining to user equipment (UE) group wake-up signal (WUS) in narrowband IoT (NB-IoT) are described. A wireless network indicates to a plurality of user equipment (UEs) a paging configuration of a UE-group wake-up signal (WUS) for one or more groups of UEs among the plurality of UEs in an NB-IoT cell. The paging configuration may be related to a discontinuous reception (DRX) cycle and a value related to UE identification of each UE in the one or more groups of UEs. The wireless network also transmits the UE-group WUS to the one or more groups of UEs.

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: A method of user equipment (UE) autonomous release RRC connection to reduce power consumption and signaling overhead is proposed. UEs sending small amount of data with long period, e.g., Machine-Type Communication (MTC) and Narrow-Band Internet of Things (NB-IoT) UEs, are allowed to be released autonomously after sending a given amount of data with corresponding request and configuration procedures. In one embodiment, UE sends an RRC connection request with UE autonomous release request, and receives an RRC setup message with UE autonomous release information. UE then transmits an RRC setup complete message with piggybacked uplink data. UE autonomously releases to Idle state upon expiry of an inactivity timer.
