Description

Method and device for processing resource configuration information, terminal device

Technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a method and device for processing resource configuration information, and a terminal device.

Background technique

WLAN (Wireless Local Area Network) is based on radio frequency radio communication technology and operates in the 2.4 GHz and 5.8 GHz bands. The user equipment (User Equipment) that accesses the WLAN base station shares the channel resources of the WLAN base station, and uses the access method based on the CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) mechanism to compete. Use channel resources. The CSMA/CA mechanism requires the user equipment to adopt the “listen to listen” mechanism to listen to the channel before sending data. It can detect the channel idle before it can start data transmission and randomly roll back in the event of a collision to ensure the user. The device occupies the fairness of the channel.

The WLAN-based TDMA system relies on the physical layer technology of the WLAN, and the upper layer uses the TDMA mechanism for processing, and performs resource allocation and user scheduling in a TDMA manner. The WLAN-based TDMA system adopts the WLAN physical layer technology, and the physical layer processing method is consistent with the WLAN system. The physical layer of the base station and the physical layer of the user equipment occupy the entire allocated bandwidth resource when transmitting data, and the upper layer adopts a TDMA mechanism, and each user equipment The time division multiplexes the channel, and the base station allocates different time slot resources to different user equipments, and the user performs data transmission and reception in the specified time slot resources. In the system, the base station uniformly allocates time slot resources for the user equipment, and the downlink base station transmits data to the user equipment according to the allocated time slot resource occupation channel, and the user equipment can receive, and when uplinking, the user equipment is different from the WLAN based on The CSMA/CA mechanism controls the data transmission by itself. The user equipment is allocated time slot resources by the base station. The user needs to send data in the time slot resource specified by the base station. Therefore, the user equipment needs to know in advance that it is allocated before the data is sent. For the gap resource, the base station needs to inform the user of the resource configuration information related to the device in advance.

In a WLAN-based TDMA system, a base station transmits information to a user equipment along with control frames, management frames, and data frames in the WLAN system. A beacon frame is a type of management frame in 802.11. It is broadcast periodically. It generally carries the basic information of the WLAN base station. The user equipment completes the network access and synchronization of the device according to the Beacon frame. The frame body of a Beacon frame has a variable length, and the information content carried therein can be customized. In the existing WLAN-based TDMA system, the beacon frame is used as the bearer for the configuration of the time slot configuration information. It is convenient to use the Beacon frame to transmit information. The time slot configuration information to be sent needs to be filled in the beacon frame frame body. The remaining length is sufficient, and the demodulation performance of the Beacon frame is superior, which ensures that the user equipment successfully receives the slot configuration information. However, the frame length of the Beacon frame is limited, and the necessary information including the user's network access and synchronization needs to be included, and the content of the customized information for transmission is limited. In the existing WLAN-based TDMA system, only the time slot configuration information is usually transmitted. Give the user device. Meanwhile, in a WLAN-based TDMA system, the time slot configuration information needs to be determined according to the structure of a frame and a time slot, and one frame and time slot structure corresponds to a time slot configuration.

In the prior art, the WLAN-based TDMA system predetermines the frame format and the time slot configuration. The base station allocates time slots to the user equipment, and uses the Beacon frame to inform the user equipment of the time slot configuration information, and the system has a fixed time slot structure. When the time slot structure in the system changes, the time slot configuration information of the user equipment changes correspondingly, and the time slot configuration information transmitted in the Beacon frame also needs to be changed accordingly, and the information in the Beacon frame frame body is correspondingly reset. Moreover, the channel occupation time is allocated to the user equipment according to the time slot, and the actually allocated time slot resource does not meet the data transmission requirement of the user equipment. When the allocated time slot is small, the data cannot be completely transmitted, and when the allocated time slot is large, the time zone is taken. The waste of time slot resources. Moreover, the amount of information carried in the Beacon frame is large, and the system overhead is large.

In this embodiment, the Beacon frame period is a period in which the Beacon frame is periodically sent. In the actual application, after the Beacon frame reassembly is completed, a Beacon frame period for transmitting the recombined Beacon frame needs to be selected as the designated Beacon frame period. The number of scheduling user equipments that can add resource configuration information in the Beacon frame period is not less than the maximum number of schedulable users in the Beacon frame period. The maximum number of schedulable users in the Beacon frame period refers to the maximum number of users that the base station can schedule during the period of the Beacon frame period, that is, the maximum number of users that the base station can allocate the transmission time during the period.

In the embodiment of the present invention, the sending the recombined Beacon frame to the at least one user equipment in step S12 is specifically implemented by the following steps:

In this embodiment, the re-established Beacon frame carries the resource configuration information of the user equipment, and when the base station sends the re-established Beacon frame, the base station specifically sends the information that changes in the resource configuration information of the user equipment.

In an actual system, the number of users scheduled by the base station is variable in one frame period, and the execution periods of different algorithms are different. The variable transmission method is used in the Beacon, and only the configuration information that changes in the resource configuration information of the user equipment is carried. The resource configuration information of more users can be transmitted to achieve the purpose of carrying multiple user equipment resource configuration information at a time.

The start time and the end time are used in the resource configuration information to indicate the channel occupation time of the user equipment, and the fixed time slot is not specified, and is applicable to systems with different time slot configurations. When the frame structure or time slot configuration information of the system changes, there is no need to Modify the Beacon frame. The base station carries the resource configuration information of multiple user equipments through the Beacon frame, which reduces the large amount of information exchange between the base station and the user equipment due to the TDMA mechanism, which greatly saves system overhead. The Beacon frame also ensures that the user equipment receives the resource configuration information. Success rate.
