20210352742 | RANDOM ACCESS TRANSMISSION METHOD AND TERMINAL - A random access transmission method and a terminal are provided. The method includes: obtaining resource allocation information for random access, where the resource allocation information indicates at least two candidate random access resources, and the candidate random access resources include candidate resources for sending data; selecting a target random access resource from the at least two candidate random access resources according to a preset selection rule; and sending a random access request message over the target random access resource. | 2021-11-11 |
20210352743 | COMMUNICATION METHOD AND APPARATUS - Embodiments of this application disclose a communication method and apparatus, to reduce a latency of random access of a terminal device. The method in the embodiments of this application includes: sending, by a terminal device, a first message to a network device, where the first message includes a random access signal and information used for contention resolution, and the random access signal and the information used for contention resolution are transmitted by using pre-assigned resources; and receiving, by the terminal device, a response message for the first message from the network device, where the response message is used to indicate a random access status of the terminal device. | 2021-11-11 |
20210352744 | RANDOM ACCESS METHOD AND DEVICE - Embodiments of this disclosure provide a random access method and a device. The method includes: initiating second random access after first random access fails, where first uplink data in the first random access and second uplink data in the second random access are the same in data size, the first uplink data is uplink data corresponding to a first resource for the first random access, the second uplink data is uplink data corresponding to a second resource for the first random access, the first random access includes two-step random access or four-step random access, and the second random access includes two-step random access or four-step random access. | 2021-11-11 |
20210352745 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM - A method and an apparatus for transmitting and receiving a signal in a wireless communication system, according to one embodiment of the present invention, are characterized by detecting one or more SSBs, selecting some SSBs from among the detected SSBs, and transmitting PRAM through an RO which succeeds in LBT, among ROs corresponding to the selected SSBs. | 2021-11-11 |
20210352746 | MOBILE PLATFORM COMMUNICATION METHOD, DEVICE, SYSTEM, AND STORAGE MEDIUM - A communication method includes generating a first connection request including verification information of a mobile platform, and sending the verification information of the mobile platform to a first control terminal communicatively connected to the mobile platform, so that a second control terminal receives the verification information of the mobile platform obtained by the first control terminal and generates a second connection request. The method further includes establishing a mobile network communication link with the second control terminal after verification of the verification information in the first connection request and verification information in the second connection request is passed. | 2021-11-11 |
20210352747 | METHOD FOR DATA TRANSMISSION AND ESTABLISHING UNICAST CONNECTION BASED ON SIDELINK - A method for data transmission and establishing unicast connection based on sidelink includes: sending a connection establishment request message for establishing a unicast connection with a second terminal to the second terminal, for determining by the second terminal, whether to agree to establish the unicast connection with the first terminal based on the connection establishment request message; receiving a connection establishment admission message returned by the second terminal; and establishing the unicast connection with the second terminal based on the connection establishment confirmation messages. | 2021-11-11 |
