    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 K TOs 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: A feedback information transmission method, a base station, and user equipment are provided. The feedback information transmission method includes: receiving, by a base station, uplink data separately sent by a plurality of user equipments (UEs); determining, by the base station, feedback information for uplink data sent by each of the plurality of UEs, where the feedback information indicates an acknowledgement (ACK) or a negative acknowledgement (NACK); and transmitting, by the base station by using one control channel, a plurality of pieces of feedback information respectively corresponding to the uplink data sent by the plurality of UEs.

    Abstract: Embodiments of the present invention relate to the communications field, and provide a signal transmission method and apparatus, which can effectively resolve a resource waste problem of user data resource elements and improve system power utilization. The method includes: determining, by a base station, a first parameter value of a user data resource element RE, an initial parameter value of a demodulation reference signal resource element DMRS RE, and a compensation parameter value of the DMRS RE; determining, by the base station according to the initial parameter value and the compensation parameter value, a second parameter value required for transmitting a DMRS; and transmitting, by the base station, the DMRS, the user data, and the compensation parameter value to user equipment, so that the user equipment demodulates the user data.

    Abstract: The present application discloses a signal processing apparatus and method, the method includes: receive an analog signal; adjust a frequency band of the analog signal to a lowest frequency band when a frequency band of the analog signal received by the receiving unit falls outside the lowest frequency band in multiple preconfigured frequency bands; process, by using a signal processing channel in the lowest frequency band, the analog signal whose frequency band has been adjusted to the lowest frequency band. The method provided in the embodiments of the present application processes signals of different frequency bands by using a processing channel in a lowest frequency band. In this way, only a relatively small quantity of radio-frequency link components are required to implement processing of the signals of the different frequency bands, which reduces a link size of a communications system.
