Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable storage medium for transport block size (TBS) configuration. In example embodiments, a terminal device transmits a random access preamble to a network device. The terminal device receives a random access response from the network device. The random access response includes a resource allocated for a reference TBS. Based on the reference TBS, the terminal device determines a TBS for transmitting data to the network device. Then, the terminal device transmits the data to the network device by using the determined TBS and the allocated resource. This TBS configuration is more flexible.

Abstract: Method, apparatus and computer program product where a base station broadcasts a signal indicating that at least one time-frequency region, which is unused by a data transmission in a first radio access technology, is available for a transmission, allowing the base station to maintain support for and/or extending coverage of certain legacy user equipment. Such a transmission includes system information for a second radio access technology, wake-up signal, synchronization signal, and/or extension of the data transmission. Thereafter, the base station transmits such a transmission in the at least one time-frequency region that was indicated.

Abstract: Various communication systems may benefit from enhanced cell capacity. For example, certain embodiments may benefit from improved packet capacity by managing transmissions in a cell. A method, in certain embodiments, may include determining at a network node whether a packet is of a service type. The service type may indicate that the packet is discardable. The method may also include calculating at the network node a probability factor or a scheduling adjustment factor for transmission of the packet, when it is determined that the packet is of the service type. In addition, the method may include determining at the network node whether to transmit the packet to a user equipment based on the probability factor, or adjusting at the network node a scheduler metric based on the scheduling adjustment factor.

Abstract: Techniques of defining a transmission scheme for NB-IoT data include determining the TBS based on 16-quadrature amplitude modulation (QAM) analysis but use quadrature phase-shift keying (QPSK) for modulation. For example, a base station (eNB) may determine that a UE is configured to receive or transmit data with 16-QAM modulation via capability signalling from the UE. Upon performing this determination, the eNB transmits configuration data to the UE, e.g., via DCI, configuring the UE to receive data over a narrowband physical downlink shared channel (NPDSCH) using 16-QAM modulation. Part of the configuration data indicates whether the UE is to support 16-QAM modulation with or without repetition via radio resource control (RRC) parameter modulation-restriction-Repetitions. Depending upon this indication, the UE may use quadrature phase-shift keying (QPSK) rather than 16-QAM despite selecting or being assigned a TBS based on 16-QAM modulation.
