Abstract: A method includes: A first device performs device discovery when detecting a preset trigger signal acting on to-be-shared data. The first device establishes physical links with n discovered second devices, where Wi-Fi direct connection functions of the first device and the n second devices are enabled. The first device sends the to-be-shared data to a target device when detecting a selection signal of the target device, where the target device is one of the n second devices. According to embodiments of this application, the first device performs device discovery when detecting the preset trigger signal acting on the to-be-shared data, and establishes the physical links with the n discovered second devices before the target device is selected for data transmission.

Abstract: Disclosed are a hypertext transfer protocol (HTTP) request transmission method and device. The HTTP request transmission method and device resolve a problem that data finally obtained through splicing is invalid because dividing an original HTTP request into a plurality of HTTP requests to pull data from different content distribution network (CDN) servers may cause inconsistency of the pulled data. When an electronic device needs to download data from a plurality of CDN servers, an overlapping range may be designed for byte ranges allocated to the different CDN servers. This means that the electronic device downloads data in the overlapping range from all the different CDN servers. Therefore, this part of data is used to check consistency of the data pulled from the different CDN servers. When determining that the data pulled from the different CDN servers is consistent, the electronic device may splice the data to obtain finally required data.

Abstract: This application provides a data transmission method. The method includes: An electronic device first establishes an MPTCP connection to an application server, where the MPTCP connection includes two TCP connections. Then, the electronic device receives indication information from an application server, where the indication information includes a type identifier and a parameter. When the type identifier indicates a low data transmission delay requirement, the electronic device receives, in a first time period after the electronic device receives the indication information, the data stream by using a first TCP connection. When an accumulated data amount actually received by the electronic device in the first time period is less than a product of the parameter and duration corresponding to the first time period, the electronic device receives the data stream in a second time period by using both the two TCP connections.

Abstract: The present disclosure discloses a multichannel PIM digital cancellation circuit, including a first frequency-shift variable rate module, a second frequency-shift variable rate module, a first conversion circuit, a second conversion circuit, a duplexer, a second transmission duplexer, a channel combiner, a third conversion circuit, a cascaded filter circuit, a PIM canceller, a feedback circuit, and a first adder. The cascaded filter circuit compensates for channel responses such as a delay difference or a phase difference generated after a transmit signal passes through a digital domain downlink, a digital-to-analog converter, and an analog domain downlink; the cascaded filter circuit simulates a group delay unevenness characteristic of the duplexer in the multichannel PIM digital cancellation circuit; a cascaded filter fits an S parameter of the channel combiner in the multichannel PIM digital cancellation circuit, and precisely fits a combining process of the channel combiner in a digital domain, so that a signal capable of canceling a PIM interference signal of a multi-transmission and multi-reception inter-mediate radio frequency system that includes the channel combiner is finally generated in the present disclosure.

Abstract: When receiving a first data frame sent by a transmitting apparatus, a receiving apparatus may return error indication information including an identifier of at least one erroneous codeword group to the transmitting apparatus if it is found that an error occurs in an initial codeword of the first data frame. The transmitting apparatus may obtain the erroneous codeword group and encode the erroneous codeword group, and retransmit a part of a sub check codeword obtained through encoding to the receiving apparatus. The receiving apparatus may obtain a third check matrix based on a first check matrix, a second check matrix, and a location of the at least one erroneous codeword group in the initial codeword, and re-decode the retransmitted partial sub check codeword and content of the first data frame together based on the third check matrix, so as to obtain a correct initial codeword.

Abstract: A signal sending and demodulation method, a device, and a system are provided, relate to the field of communications technologies, and can resolve a prior-art problem of a low user throughput caused by mismatch between poor PDCCH signal demodulation performance and PDSCH signal demodulation performance. A specific solution is as follows: A base station of a serving cell obtains a first power ratio restriction set preset by a base station of at least one interfering cell; sends a preset second power ratio restriction set and the first power ratio restriction set to a terminal; and sends a second original PDCCH signal to the terminal, where a current value of a second power ratio of the second original PDCCH signal is an element selected from the second power ratio restriction set. Embodiments of the present invention are used for signal demodulation.
