Embodiment Construction
[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0036] In the first aspect, an embodiment of the present invention provides a method for acquiring a channel quality indicator (CQI) of a shared channel, see figure 1 ,include:
[0037] S101. Broadcast a group configuration message to the trunking terminals of each group in the broadband trunking system. The group configuration message is used to indicate the group identifier G-RNTI of each group, and is also used to indicate the group identifier G-RNTI assign...

The embodiment of the present invention relates to a shared channel CQI acquisition method and device, receiving method and device, in the acquisition method, a network side device (such as a base station) can broadcast a group configuration message to the trunking terminals of each group in the broadband trunking system , the group configuration message indicates the group identifier G‑RNTI and the PUCCH channel resource allocated to the group for reporting shared channel measurement feedback information. The terminals in the group can report the measurement feedback information on the designated channel when needed, so that the network side device obtains the CQI of the group's shared channel by receiving the measurement feedback information. The method provided by the embodiment of the present invention allocates PUCCH resources based on groups, so there will be no resource allocation due to too many terminals in the group, and excessive processing load will not be increased, and the network side equipment can The shared channel of the group is adaptively adjusted according to the CQI of the shared channel of the group.
Description
technical field [0001] The present invention relates to the field of communication technology, and in particular to a method and device for acquiring CQI of a shared channel, and a method and device for reporting. Background technique [0002] Adaptive Modulation and Coding (AMC) is a link adaptation technology based on the physical layer. The basic principle is to ensure the transmission quality of the link by adjusting the modulation mode and coding rate of the wireless link transmission under the condition of constant sending power. When the channel condition is poor, choose a smaller modulation method and coding rate; when the channel condition is better, choose a larger debugging method to maximize the transmission rate. [0003] In the LTE (Long Term Evolution, long-term evolution) cellular mobile communication system, the AMC control process is divided into the AMC uplink control process and the AMC downlink control process. Since the cluster shared channel only invo...
