摘要： Methods and apparatus of resource allocation (RA) for low cost machine communication type (LC-MTC) user equipments (UEs) are provided. A UE obtains one or multiple sets of resources in a mobile communication network. Each set of resources belongs to a narrow sub-band in a wider channel bandwidth, wherein the narrow sub-band comprises a plurality of contiguous physical resource blocks (PRBs). The UE determines a first set of resources from the one or multiple sets of resources based on a physical layer control signaling and transmits or receives radio signals using the first set of resources within a predefined duration. In a coverage extension mode, the UE determines a second set of resources according to a hopping pattern, while the first and the second sets of resources are occupied for transmission at different radio subframes. The UE then transmits or receives radio signals using the second set of resources.

摘要： Methods and apparatus are provided for paging enhancement for LC-MTC devices. In one novel aspect, a new paging message is used. In one embodiment, a new system information (M-SI)-paging is provided either carrying a bitmap or being generated from specific M-P1-RNTI sequences to indicate the modified SI messages. In another embodiment, a new RRC-paging is used through a UE-specific message, a multicast message, or a broadcast message to inform a UE to establish a RRC connection. The new paging message is either a sequence or an encoded data packet transmitted without control information, or scheduled by M-PDCCH. In another novel aspect, the new paging message is transmitted within one or more cells by a broadcast mechanism to achieve a maximal CE level the one or more cells support, or a multi-cast mechanism to support a specified CE level range, or a unicast mechanism to support a CE level.

摘要： These disclosed embodiments describe a method for a device, particularly a low-complexity MTC device, to enhance coverage by optimizing HARQ operation with repetitions. For downlink data transmission, a device receives the DL (normal or primary) grant from BS to determine reception of the initial data transmission or full-adaptive retransmission. A device may receive a secondary DL grant for receiving the data with partial-adaptive retransmission. For uplink data transmission, a device receives the UL normal (or primary) grant to perform initial data transmission or full-adaptive retransmission. The device may receive a secondary UL grant for retransmission according to the combined information from the secondary UL grant and the latest UL normal grant. The secondary grant can be a truncated normal grant for partial-adaptive HARQ retransmission with less control information and resource consumption, whereas the UL/DL normal (or primary) grant is mainly applied to support initial HARQ transmission and full-adaptive HARQ retransmission.

摘要： Methods and apparatus are provided for paging and random access response (RAR) scheduling and downlink control information (DCI) for a user equipment (UE). In one novel aspect, an SI-paging and a call-paging are transmitted separately, and scheduled by SI-Paging-DCI and call-Paging-DCI respectively. In one embodiment, a special PO is introduced for stand-alone SI-Paging scheduled by SI-Paging-DCI, and the special PO is different from the PO for call-Paging. In another novel aspect, SI-Paging is scheduled together with call-paging in the same PDSCH scheduled by call-Paging-DCI. In one embodiment, the SI-paging carries a value tag and a bitmap, wherein the value tag indicates whether any SI updates, and the bitmap indicates which one or more SIs updates. In another embodiment, the SI-Paging carries several value tags, and the number of value tag corresponds to the number of SI. The UE compares a current value tag to a stored value tag to verify whether a SI changes.

摘要： Methods are provided for HARQ with channel repetitions. In one novel aspect, the user equipment (UE) receives the resource grant and determines the type of the grant as being the initial resource grant or the secondary resource grant. The initial resource grant carries full control information and the secondary resource grant carries partial control information. In some embodiments, the determination of the type of the grant is based on the RNTI or the payload size. In another embodiment, the UE performs data retransmission based on information from the secondary resource grant and the initial resource grant. In another novel aspect, the UE receives higher layer, such the RRC layer. The UE subsequently receives UL or DL secondary resource grant for both initial transmission and the re-transmission. The UE combines the parameters in the UE-specific configuration and the received secondary resource grants for its UL transmission or DL reception.

摘要： For SL PSSCH TBS determination, a PSFCH overhead indicator carried in 2nd SCI can be used to indicate whether the average or zero PSFCH overhead is assumed for a TB across the initial transmission and re-transmission (s). This can secure the same TB across all (re-) transmissions for a TB while providing the possibility of achieving the peak data rate by only using the slots without PSFCH.

摘要： Currently, in legacy LTE, the UE will choose PCell (RRC_CONNECTD) or the serving cell (RRC_IDLE) as synchronous reference when V2X sidelink communication is out of coverage on the concerned frequency. In NR, considering the EN-DC, NE-DC OR NR-DC deployment, it's not necessary for the UE to always choose PCell as the synchronous reference. One option is UE will always choose gNB as the synchronous reference. When both PCell and PSCell are gNBs, UE could choose PCell as the synchronous reference. Another option is UE will choose PCell or PSCell based on their RSRP values. The third option is that the network can signal a RSRP threshold. When PCell and PSCell's RSRP will be higher than this threshold, the UE will at first choose gNB as synchronous reference because gNB can give better timing to UE. In other case, the UE can choose synchronous reference based on PCell and PSCell's RSRP value.
