Problems solved by technology

[0003] In a traditional data transmission system, the terminal interacts with the base station to obtain control messages such as system configuration, operating frequency band, and resource allocation, such as resource allocation when the base station performs downlink transmission and resource conditions that the terminal can use for uplink transmission, etc., and transmits these Control messages take up valuable system bandwidth

Embodiment 1

[0040] In said step 101, the information field can be represented as the form of the number of terminals+BITMAP (bitmap) sequence, wherein the number of terminals indicates how many terminals in the group need to adjust the follow-up working mode according to the control message, and the BITMAP sequence includes several bits, usually bit '0' indicates that the corresponding terminal does not need to adjust the subsequent working mode after receiving the control message, and bit '1' indicates that the corresponding terminal needs to adjust the subsequent working mode after receiving the control message, usually The first bit in the BITMAP sequence corresponds to the terminal whose relative position is 1 in the group, the second bit corresponds to the terminal whose relative position is 2 in the group, and so on until the number of bits with the value '1' in the BITMAP sequence is equal to the previous The BITMAP sequence is aborted when the number of endpoints described.

Embodiment 3

[0046] In the step 101, the information field can be expressed in the form of statistical identification + number of terminals + BITMAP sequence, wherein the statistical identification is usually represented by a bit, and when it is '0', it means that the terminal number field indicates how many there are in the group The terminal does not need to adjust the subsequent working mode according to the control message. When it is '1', it means that the terminal number field indicates how many terminals in the group need to adjust the subsequent working mode according to the control message. The BITMAP sequence contains several bits, usually Bit '0' indicates that the corresponding terminal does not need to adjust the subsequent working mode after receiving the control message, and bit '1' indicates that the corresponding terminal needs to adjust the subsequent working mode after receiving the control message, usually in the BITMAP sequence The first bit corresponds to the terminal ...

Abstract

The invention provides a method for reducing the system control expense based on the group for the to-be solved technical problem, which can reduce the control expense of the data transmitting system to achieve the purpose of enhancing the system transmitting efficiency. The BITMAP serial length of the method is various; the method comprises: base station carries the character section A and BITMAP serial for indicating the efficient number character section A for the BITMAP serial and the BITMAP serial; arranging the corresponding digit in the BITMAP serial of the terminal needs to adjust the working way; after receiving the control information, obtaining the BITMAP serial via processing the statistic of the subsequence effective digits of the control message character section A. the invention conforms whether the method needs to adjust the working way in the BITMAP serial.

Description

technical field [0001] The invention belongs to the field of data transmission and relates to a group-based control message transmission method in a data transmission system. Background technique [0002] In a data communication system, a base station refers to a device that provides services to a terminal. The base station communicates with the terminal through the uplink and downlink. The downlink refers to the direction from the base station to the terminal, and the uplink refers to the direction from the terminal to the base station. Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. [0003] In a traditional data transmission system, the terminal interacts with the base station to obtain control messages such as system configuration, operating frequency band, and resource allocation, such as resource allocation when the base station performs downli...
