Abstract: Embodiments of this application provide a data sending method, a data receiving method, a transmit-end device, and a receive-end device. The data sending method provided in the embodiments of this application may include: performing scrambling code initialization to generate a scrambling code; scrambling a data block based on the scrambling code; repeatedly sending the scrambled data block; performing scrambling code initialization to generate a new scrambling code when an interval after previous scrambling code initialization of the data block is greater than or equal to a preset scrambling code initialization parameter threshold; scrambling the data block again based on the generated new scrambling code; and repeatedly sending the data block scrambled again. The embodiments of this application can improve efficiency of data transmission between a transmit-end device and a receive-end device.

Abstract: This disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for obtaining an uplink-downlink carrier frequency spacing. The method for obtaining an uplink-downlink carrier frequency spacing may include initiating, by user equipment (UE), a request in a first cell to access an NB-IoT, and receiving an indication message sent by a base station. The method may also include determining, by the UE according to the indication information, an uplink-downlink carrier frequency spacing corresponding to the first cell. Therefore, the base station can notify the UE of the uplink-downlink carrier frequency spacing corresponding to the first cell, so that the terminal obtains a correct uplink carrier frequency.

Abstract: The present disclosure relates to a method and an apparatus for sending and receiving a downlink data block of a packet data service. A network side adds indication information of downlink data modulation modes to a downlink data block, where the downlink data block includes first information and second information; the network performs symbol mapping processing on the first information by using a first modulation mode to obtain a first modulated signal; the network performs symbol mapping processing and data pre-processing on the second information by using a second modulation mode to obtain a second modulated signal; the network combines these two modulated signals to obtain an aggregate modulated signal; and the network sends the aggregate modulated signal. With the present disclosure, throughput of downlink data is increased while a USF compatibility between more types of low-capability mobile terminals is considered.

Abstract: A resource allocation method includes: determining a resource block allocation field in downlink control information, where when a value indicated by five least significant bits of the resource block allocation field is less than or equal to 20, the five least significant bits of the resource block allocation field indicate a resource that is allocated within an indicated narrowband by using an uplink resource allocation type 0; or when a value indicated by five least significant bits of the resource block allocation field is greater than 20, the resource block allocation field indicates a quantity of resource block groups allocated to a terminal device and an index of a starting resource block group allocated to the terminal device. The method provided in this embodiment improves the coverage capability of the network. The method can be applied to the Internet of Things, such as MTC, IoT, LTE-M, M2M, etc.

Abstract: Embodiments of the present disclosure disclose a method for determining a frequency resource, and an apparatus. The method includes: first determining, by user equipment (UE), a power headroom report; and subsequently sending, by the UE, the power headroom report (PHR) to a base station in a random access process, where the power headroom report may be carried by a related information segment of message 3 (Message 3) sent by the UE to the base station. According to the solutions provided in the present disclosure, a base station can obtain, in a timely manner, a basis for performing scheduling configuration when UE performs current uplink data transmission, and can more accurately configure power control and scheduling information for the UE. This avoids allocating the UE a channel that exceeds an uplink transmission capability of the UE, and thereby avoids an uplink bandwidth waste.
