Problems solved by technology
When the coverage levels of the user equipment are different, when the user equipment that needs more repetitions and the user equipment with good channel quality compete to send data together, it will make it difficult for the user equipment that needs more repetitions to compete. Get resources, "starve to death" phenomenon
However, for this situation, there is no good solution in the prior art

Embodiment 1
[0150] Embodiments of the present invention provide broadcast control bandwidth allocation and data sending and receiving methods, such as figure 1 shown, including:
[0151] 101. The base station acquires location information and channel distribution information of the current user equipment.
[0152] Wherein, the location information of the user equipment is used to indicate the location coordinates of the current user equipment, and the channel distribution information is used to indicate the channel used by each user equipment and the repetition times of sending data on the channel. For example, the channel distribution information of user equipment A includes that the channel used by user equipment A is channel X, and the number of repetitions used by user equipment A to exchange data with the base station on channel X is 64X (ie repeated transmission 64 times).
[0153] Specifically, the location information of the user equipment includes coordinate location information...
Embodiment 2
[0186] Embodiments of the present invention provide broadcast control bandwidth allocation and data sending and receiving methods, such as Figure 10 shown, including:
[0187] 301. The base station counts location information and channel distribution information of each user equipment, and obtains user equipment allocation ratios of data channels and control channels corresponding to each repetition number.
[0188] When performing data interaction between the base station and the user equipment, the area covered by the base station is divided into different levels according to the number of times data needs to be repeatedly sent. Such as figure 2 As shown, the A area is a common coverage area, and the data interaction between the base station and the user equipment can be completed without spreading (called 1X); the B / C area is an extended coverage area, which needs to use the spread spectrum method, that is, repeat Sending (for example, repeating 8 times is called 8X, re...
Embodiment 3
[0233] Embodiments of the present invention provide a base station, such as Figure 11 shown, including:
[0234]The first acquiring module 01 is configured to acquire location information and channel distribution information of the current user equipment, the location information of the current user equipment is used to indicate the location coordinates of the current user equipment, and the channel distribution information is used to indicate the current user equipment uses channel information and the number of repetitions used;
[0235] The preprocessing module 02 is configured to determine the bandwidth and number of data channels and control channels, and the corresponding repetition times of data channels and control channels according to the location information and channel distribution information of each user equipment;
[0236] An updating module 03, configured to update the bandwidth allocation information according to the bandwidth and number of the data channel a...

Abstract
Embodiments of the present invention provide broadcast control bandwidth allocation and data sending and receiving methods and devices, which relate to the field of communication, and transform the traditional channel public mode into time-frequency multiplexing of channels according to the real-time usage of user equipment, which greatly increases the original Channel utilization efficiency. The method includes: obtaining location information and channel distribution information of the current user equipment; preprocessing the time-frequency resources of the channel according to the location information and channel distribution information of the current user equipment; The bandwidth and number of channels, and the number of repetitions corresponding to each data channel and control channel update the bandwidth allocation information; send broadcast information to the user equipment through the broadcast channel, and the broadcast information in the broadcast channel includes at least bandwidth allocation information, so that The user equipment determines, according to the broadcast information, the control channel and the data channel for the first number of repetitions required for data transmission.
Description
technical field [0001] The invention relates to the communication field, in particular to a broadcast control bandwidth allocation and data sending and receiving method and device. Background technique [0002] With the development of science and technology, the data interaction between the base station and the user equipment is more and more frequent, and the quality requirements of the data interaction are also greatly improved. Quality requirements are getting higher and higher. [0003] In the existing technology, M2M (machine to machine, Internet of Thingsmachine-to-machine communication) mainly considers two factors of cost and coverage area. The coverage area is expanded by repeated transmission through the method of spread spectrum, and the transmission mode of narrowband data is used to reduce the User equipment cost. For example, within the coverage range of the first distance near the base station is a normal coverage area, which can meet the data interaction r...
