A data processing method includes: selecting, by a network device according to a downlink control information (DCI) format of DCI used for scheduling data, a modulation coding scheme (MCS) mapping table to be used, the MCS mapping table including a mapping relationship between multiple MCS indication information and multiple MCSs, the DCI format including a first DCI format and a second DCI format; determining, by the network device according to the MCS mapping table and an MCS used for processing the data, an MCS indication information carried in the DCI; and sending, by the network device, the DCI carrying the MCS indication information to a terminal device.

Methods, systems, and devices for wireless communications are described. A wireless device may configure one or more first sets of resources of a radio frequency spectrum band associated with a first pathloss mode, and may configure one or more second sets of resources associated with a second pathloss mode. Each set of resources may be configured with some transmission timing parameters and frame structure, such that a transmission time interval (TTI) associated with the first pathloss mode may be different from the TTI associated with the second pathloss mode. The wireless device may communicate with a second wireless device using the one or more first sets of resources based on identifying a pathloss value is below an identified pathloss threshold. Additionally, the wireless device may communicate with a third device using the one or more second sets of resources based on identifying a pathloss value satisfies the identified pathloss threshold.

Embodiments of the present disclosure provide a server data sending method and a server data sending apparatus. The method can include: acquiring, by a server, crystal oscillator error information and operating rate information of a terminal; setting, by the server, preamble length information according to the crystal oscillator error information and the operating rate information; and sending, by the server, a downlink data frame to the terminal, the downlink data frame comprising a preamble aligned with the preamble length information.

In a wireless network, a frame structure may include a padding duration at the start of every half subframe to ensure that an integer number of symbols fit within a duration of the half subframe. In some aspects, to avoid wasting time domain resources, the padding duration may be utilized for other purposes. For example, because a single carrier waveform is not bound to a fixed Fast Fourier Transform size, a wireless node may use the padding duration to transmit a single carrier symbol that has a shorter length than a full symbol associated with a subcarrier spacing. Additionally, or alternatively, in cases where a wireless node is configured to transmit or receive a signal in a first symbol of a half subframe that is associated with a different power level than a preceding symbol, the padding duration may be used to adapt a transmit power or a receive gain.

The present disclosure relates to a method and apparatus for configuring a resource for the transmission/reception of data. More particularly, the present disclosure relates to a method and apparatus for configuring an MCS and a TBS for an MTC terminal. Particularly, provided is a method and apparatus for determining a TBS by an MTC terminal. The method may include receiving scheduling information transmitted based on an MCS used for the MTC terminal and a TBS table and determining a TBS using the scheduling information provided by a base station.

The present disclosure described systems and methods for providing OTT services to a UE. An exemplary OTT-providing host computer includes a transceiver, a processor, and memory collective configured to provide the OTT service by initiating transmission of user data to the UE. To transmit the user data from the host computer to the wireless device, a network node sends a first control message for assigning a PDSCH, the first control message comprising a first MCS indication as described. The network node sends to the wireless device a second control message for assigning a PDSCH, the second control message comprising a second MCS indication as described. The network node transmits the user data thereafter.

In the field of wireless communication technologies, method and apparatus for determining a transport block size (TBS) of a data channel are provided. In a communication network, a terminal device receives control information from a network device. The control information includes modulation indication information and resource information of the data channel. The terminal device determines a modulation order and a code rate according to the modulation indication information, and determines number of time-frequency resources according to the resource indication information of the data channel. The terminal device determines the TBS according to the modulation order, the code rate, and the number of time-frequency resources. Based on the determined TBS, the terminal device decodes the data channel carried on the time-frequency resources or sends the data channel on the time-frequency resources.

Embodiments of the present invention prevent interference caused by the simultaneous transmission and reception of data in a constrained multi-link operation of a wireless network. According to one embodiment, first and second trigger frames are received from a wireless access point (AP) at a wireless station (STA) over first and second wireless links, respectively. First and second data frames are transmitted responsive to the first and second trigger frames over the first and second wireless links, respectively, when the difference between the ending time of the data frame transmitted responsive to the first trigger frame and the ending time of the second trigger frame is greater than a predetermined value to prevent interference.

Provided is a transmission control method for a plurality of transmitting stations which are connected to a wireless communication partner receiving station by non-orthogonal multiple access, and each of which is capable of transmitting a same signal to the receiving station by repetition for a predetermined number of times at a predetermined cycle, wherein an information processing apparatus executes: acquiring information indicating a code word length for each of the plurality of transmitting stations to use for the repetition; and assigning, to each of the plurality of transmitting stations, transmitting power for ensuring a power difference which is required between transmitting stations, so that the shorter the code word length the higher the receiving power at the receiving station.

A base station may receive uplink data identifying uplink performance indicators associated with user equipment connected to the base station, and may receive tuning factors associated with shared channel traffic received by the user equipment and quality of service requirements of the user equipment. The base station may determine a total score associated with utilizing a long duration physical uplink control channel (PUCCH) format for uplink control information based on the uplink data and the tuning factors. The base station may determine that the total score satisfies a threshold score and may switch to the long duration PUCCH format for the uplink control information based on the total score satisfying the threshold score. The base station may perform one or more actions based on switching to the long duration PUCCH format for the uplink control information.
