Abstract: The present disclosure provides a method and an apparatus for determining a Listen Before Talk (LBT) mode, as well as a method for LBT mode switching. The method includes: determining (100) an LBT mechanism and/or an LBT mechanism parameter set based on related indication information and/or priority information and/or measurement information; and performing (101), by a transmitting device, contention-based channel access based on the determined LBT mechanism and/or LBT mechanism parameter set. With the present disclosure, an LBT mode can be determined. With the selection of the LBT mode, it is possible to avoid waste of channel resources and indication information due to an improper LBT mode, thereby improving an efficiency of contention-based channel access.

Abstract: The present disclosure provides a method and an apparatus for sequence determination, a device and a storage medium. The method for sequence determination includes: mapping a first bit sequence having a length of K bits to a specified position based on M_index to obtain a second bit sequence; applying Polar encoding to the second bit sequence to obtain a Polar encoded bit sequence; and selecting T bits based on the Polar encoded bit sequence as a bit sequence to be transmitted, where K and T are both non-negative integers and K≤T.

Abstract: Provided are methods and devices for determining or acquiring radio resources. The method for determining radio resources includes that: predefined information is acquired, wherein the predefined information includes indication information of a dedicated node, and/or, measured values of Component Carriers (CCs) on a multisystem shared spectrum, wherein the indication information includes: information of the maximum number of CCs, which are available to a system, on the multisystem shared spectrum, and the measured values are acquired according to preset signals on the CCs; and the maximum number of CCs, which are available to a system, on the multisystem shared spectrum is determined according to the predefined information. By the technical solution, the problem of interference between systems may be solved, and spectrum utilization efficiency is improved.

Abstract: An unlicensed carrier contention method and apparatus are provided. The method comprises that: a Licensed Assisted Access (LAA) device implements a Clear Channel Assessment (CCA) or an Evolution Clear Channel Assessment (eCCA) on a channel; if the result of the assessment is ‘idle’, the LAA device decrement N and determines whether or not the decremented N is greater than 0, wherein N is a natural number; and if the result of the determination indicates that the decremented N is not greater than 0, the LAA device uses an unlicensed carrier for data transmission. The disclosure addresses the problem that no contention withdrawal mechanism or procedure suitable for an LAA system is provided in the conventional art.

Abstract: A method and apparatus for allocating resources to carrier response information feedback are disclosed. Wherein, when Transmit Power Control (TPC) command in Downlink Control Information (DCI) for each secondary component carrier in carrier aggregation is different, Physical Uplink Control Channel (PUCCH) resources allocated to the response information feedback of the secondary component carriers are high-layer configuration PUCCH resources designated by TPC command in the DCI which triggers data services in the secondary component carriers. The present solution can not only effectively feedback response information, but also can effectively suppress occurrence of unnecessary downlink retransmission.
