Embodiment 1

[0116] When the sending end needs to communicate with the receiving end, and there is no status record of the receiving end locally, or the current status of the receiving end is recorded as the working status of the auxiliary module. The working state of the auxiliary module refers to the state in which the main module cannot communicate normally and needs to rely on the auxiliary module to receive information. When the AP is the serving base station of the STA, the AP has the sleep state information (deep sleep / power saving or normal sleep / power saving) of the STA. When the AP is not the serving base station of the STA, there is no status information of the corresponding STA on the AP, and the upper layer entity requires the AP to wake up a specific STA.

[0117] When the AP sends a wake-up message to the STA, and finds that the working channel of the STA before sleep is different from its current working channel, the wake-up signal carries the target working channel informati...

Embodiment 2

[0126] In order to support STA mobility, if the upper layer entity requires the AP to wake up / page a certain STA, and the STA does not belong to the AP, the AP will notify the STA in the wake-up signal or paging signal that it has moved out of the range of the original serving AP. .

[0127] The AP indicates the identity information of the sender in the wake-up signal.

[0128] Alternatively, the AP indicates in the wake-up signal whether the service access point has been replaced, and the identity information of the sender.

[0129] Alternatively, the AP indicates in the wake-up signal whether the serving access point has been replaced.

[0130] The sender identity information may be the sender's MAC address information, or partial address information, or BSScolor information, or other identification information that can be used to identify the sender's identity.

[0131] Whether the service access point has been replaced can be 1 bit indicating whether the STA is in the or...

Embodiment 3

[0141] In order to support STA mobility, when the AP sends a wake-up signal, it indicates whether the other party needs to perform a network access operation, and the type of network access operation when it needs to perform a network access operation.

[0142] The power saving module receives the wake-up signal sent to itself, parses the network access control information therein, wakes up the main module, and transmits the control information to the main module.

[0143] If the above control information indicates that the access network operation needs to be performed, and the type of network access operation is the traditional network access authentication process, after the main module wakes up, it does not try to connect to the original service AP, and directly initiates a new network access process and performs channel scanning. , authentication, association, obtain IP, connect with its own server, and obtain data packets or instructions that were not successfully deliver...

Abstract

The invention discloses a control information transmission method and device. The control information transmission method comprises the steps that a first station sends a wireless signal containing control information, wherein the control information is used for notifying the designated second station in a dormant state to perform one or more operations as follows: state updating, sleep mode switching, releasing of the dormant state and operation after releasing of the dormant state; an auxiliary module of the second station receives and decodes an awakening signal and sends the decoded control information and the identity identification information to a control module; the control module of the second station judges whether the second station is a target second station of the awakening signal according to the identity identification information, and analyzes and completes the operations indicated in the control information.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for transmitting control information. Background technique [0002] In wireless communication systems, power saving performance has always been valued. With the development of the Internet of Things, a variety of applications will bring a large number of self-powered devices to the wireless network. Due to the large number of devices or due to the limitation of the application environment, it is not feasible to change batteries or recharge frequently, so it is necessary to put forward higher power saving requirements for the design of such applications and devices. [0003] Traditional wireless local area network (WLAN, Wireless Local Area Networks) systems and cellular network systems have corresponding power-saving mechanisms. When there is no need for communication, the terminal device enters a sleep state and wakes up at a predeterm...
