Abstract: A wireless transmission parameter adjustment method and a related device. The method includes monitoring a frequency parameter of a cell, determining, in response to detecting that the frequency parameter of the cell increases, a location relationship between a first terminal and an access network device, wherein the first terminal is a terminal camping on the cell, and adjusting a target power parameter of the first terminal according to the location relationship between the first terminal and the access network device, so that a radio remote unit power does not exceed a preset power, where the target power parameter is a power parameter other than a cell-specific reference signal power.

Abstract: Embodiments of the present disclosure provide concurrency control, including receiving a plurality of transaction operation requests, where each transaction operation request includes operation object information and operation type information, the operation object information is used to indicate an operation object of the transaction operation request, and the operation type information includes a write operation or a read operation, making a lock-use application according to the at least two transaction operation requests, and determining, according to a requested lock status and a current lock status in the lock-use application, whether the application is passed, and if the application is passed, determining to perform concurrency control on the at least two transaction operation requests by using the requested lock status, where the requested and current lock statuses includes at least three modes: a shared read mode, a shared write mode, and an exclusive mode.

Abstract: A method and an apparatus for resource allocation in a local wireless node of a system of a plurality of local wireless nodes is disclosed. An inner circle subgradient resource allocation iteration is performed based on information received from at least one other wireless node of the system and an iteration parameter until a convergent result. An updated iteration parameter is provided by at least one outer circle subgradient iteration based on the convergent result of the inner circle subgradient resource allocation iteration. The inner circle subgradient resource allocation iteration is then repeated at least once using the updated iteration parameter until a convergent result. Resources are then allocated based on the iterations.
