Abstract: A method and an apparatus for determining an RBG size are provided. In the method, a network device or a terminal determines an RBG size set, where the RBG size set may include one or more possible RBG sizes; and determines a first RBG size included in the RBG size set. The network device allocates a resource to the terminal by using the determined first RBG size. The terminal determines, based on the determined first RBG size, the resource allocated by the network device to the terminal.

Abstract: This application relates to the field of communication technologies, and provides a communication method and apparatus. The method includes: A terminal device receives first downlink control information DCI from a network device through a first physical downlink control channel PDCCH. The first DCI includes a first time domain resource assignment TDRA indicator field, and the first TDRA indicator field is used to indicate a first time domain resource. The terminal device receives or sends data on a second time domain resource after determining the second time domain resource based on a time domain position of the first PDCCH and the first time domain resource. The first time domain resource is different from the second time domain resource. The method is applied to a time domain resource assignment process of the data scheduling.

Abstract: Embodiments of this application provide a data transmission method and apparatus and a storage medium. The method includes: After obtaining a first identifier and a second identifier that uniquely identify a first device, the first device scrambles, by using the first identifier, checked data obtained through CRC check. After performing channel coding on to-be-transmitted data and scrambled checked data, the first device scrambles, by using the second identifier, coded data obtained through channel coding, and finally sends scrambled data. In this way, after receiving the scrambled data, a second device may perform descrambling by using the second identifier, and then perform CRC check, to determine whether the received data is correct and determine the first identifier of the first device.

Abstract: Various embodiments provide a frequency hopping processing method and a device. In those embodiments, a symbol used to transmit a demodulation reference signal of a shared channel can be determined by a communications device. A time domain frequency hopping location of the shared channel based on the symbol used to transmit the demodulation reference signal can be determined by the communications device. In this way, frequency hopping processing of a shared channel in an NR network is implemented.

Abstract: Embodiments of this application provide a method and apparatus for determining a transport block size. The method includes: obtaining a target overhead value based on a target time-frequency resource and one or more of at least two overhead values, where the target time-frequency resource is used for uplink data transmission or downlink data transmission and includes one or more time-frequency resource units, and each overhead value is corresponding to at least one time-frequency resource unit; and determining a transport block size based on the target overhead value. It can be learned that, according to the method and apparatus for determining a transport block size provided in the embodiments of this application, a corresponding target overhead value may be determined for each of different target time-frequency resources. This is not only applicable to a scenario in which a dynamic time-frequency resource is scheduled, but also improves accuracy of determining the transport block size. Therefore, transmission performance is improved.

Abstract: In accordance to embodiments, methods, devices, and systems for determining initial transmissions in grant-free transmissions are disclosed. A UE receives a resource configuration for grant-free (GF) transmissions. The resource configuration comprises a periodicity parameter (P), a repetition number (K), and a sequence of redundancy version (RV) numbers corresponding to one or more RV types. The periodicity parameter defines a period having K transmission occasions (TOs), and each of the KTOs is associated with one RV number in the sequence of RV numbers. The UE performs an initial GF transmission of data in a TO of the K TOs in the period defined by the periodicity parameter. The TO is associated with an RV number corresponding to RV0.

Abstract: Methods and systems for dynamically activate and deactivate an allocated resource for a UE to make grant-free uplink transmission are provided. In one embodiment, a user equipment (UE) receives a Radio Resource Control (RRC) signal. The RRC signal specifies grant-free (GF) configuration information. The GF configuration information comprises an activation field and at least one other GF resource configuration field. The activation field indicates whether the UE may perform GF uplink (UL) transmissions without waiting for a downlink control information (DCI) message. Then, the UE performs a GF UL transmission in accordance with the GF configuration information in the RRC signal.
