摘要： According to the present disclosure, behaviors of a Base Station (BS) and a User Equipment (UE) pertinent to Reference Signal (RS) transmissions are discussed. BS may configure RS corresponding to a set of antenna ports in two or more groups of Orthogonal Frequency Division Multiplexing (OFDM) symbols on a short Physical Downlink Sharing CHannel (sPDSCH), where subcarrier indices used for RS transmission are different between at least two groups of OFDM symbols. Then, BS may transmit the RS to UE. UE will receive RS and perform channel estimation based on the received RS.

摘要： Embodiments of the present disclosure relate to methods and devices for uplink puncturing. In example embodiments, the terminal device obtains a first signal to be transmitted for a first service requiring a first latency. Then, the terminal device determines whether a resource block has been a shared one for the first service requiring a first latency or allocated by a network device for a second service requiring a second latency higher than the first latency. If it is determined that the resource block has been allocated for the second service, the terminal device selects a first set of resource elements based on a predefined pattern of resource elements. The first set of resource elements are discontinuously distributed in the allocated resource block. The terminal device transmits the first signal for the first service to the network device at the first set of resource elements. In this way, the low latency requirement of the first service may be met while impairing of the second service due to the missing of the REs preempted by the first service may be reduced.

摘要： According to the present disclosure, different TBS tables especially different TBS table sets are used for URLLC traffic and non-URLLC traffic. ATBS table for URLLC is selected by a network node, upon determination of traffic type as URLLC, and informed to a UE. The informing can be a TBS table index or a scaling factor. After receiving the information of TBS table selection, the UE identifies the selected TBS table from its TBS table set for URLLC, or generates a new TBS table based on the scaling factor and a corresponding TBS table.

摘要： According to the present disclosure, behaviors of User Equipment (UE) and base station (BS) pertinent to Scheduling Request (SR) and/or Buffer Status Report (BSR) as well as resource management in short Transmission Time Interval (sTTI) relevant scenarios are discussed. UE may firstly determine if the SR is triggered by a buffer status change of a delay-critical data which needs a sTTI. If so, UE will send the SR to BS on a first type of uplink control channel designed for sTTI. Otherwise, UE will send the SR to the base station on a second type of uplink control channel designed for legacy TTI.
