specific Embodiment 1

[0261] In this embodiment, the receiving end may determine resource selection information through the following steps and feed back the resource selection information to the sending end.

[0262] Step 1: The receiving end determines the configuration information of the candidate resource set; the resource set includes Q second-type resource groups; Q is an integer greater than or equal to 1;

[0263] Step 2: The receiving end receives the transmission signals on the Q second resource groups;

[0264] Step 3: The receiving end selects M resources from the resource set above; M is an integer greater than or equal to 1; when M>1, the receiving end divides the M resources into N first-type resource groups, and N<=M ;

[0265] Step 4: The receiving end feeds back the indication information of the selected M resources and the grouping indication information of the resource group of the first type to the sending end.

[0266] In the above step 1, the resource group of the second ty...

specific Embodiment 2

[0281] The implementation steps of this embodiment are similar to the specific embodiment 1. This embodiment specifically describes the principle of grouping the first type of resource groups in step 3. This embodiment performs grouping according to the received resources of the selected M resources. Wherein the receiving resources are receiving antennas; and / or receiving ports; and / or receiving weights (beams); and / or receiving sectors; and / or receiving sequences; and / or receiving time domain resources, and / or receiving frequency domain resources.

[0282] Group the selected resources according to the received resources to form N resource groups of the first type. The first implementation mode of this embodiment is as follows: Figure 14 As shown, for Q=9 transmit beams, the receiver selects {1, 2, 3, 5, 8, 9} of the 6 transmit beams, where {1, 2, 3} correspond to the same receive beam 1, and the transmit Beam {5} corresponds to receiving beam 2, and transmitting beams {8, 9...

specific Embodiment 3

[0319] The implementation process of this embodiment is similar to the specific embodiment 1. This embodiment specifically describes the division of the first type of resource groups in step 3 according to the transmission signal quality on the selected M resources or the channel quality corresponding to the resources.

[0320] In the first implementation of this embodiment, the difference in channel quality corresponding to resources in the same first-type resource group is less than or equal to the threshold R1, and the difference in channel quality corresponding to resources in different first-type resource groups is greater than the threshold R2, where the The above-mentioned R1 or R2 is agreed between the sending end and the receiving end, or configured by the sending end to the receiving end; R1 and R2 can be the same.

[0321] In the second implementation of this embodiment, the difference in received signal quality corresponding to resources in the first type of resourc...

Abstract

The invention provides feedback and acquisition methods and devices for packet indication information. The feedback method for the packet indication information comprises the steps of determining M resources from a candidate sending resource set and dividing the M resources into N first-class resource groups, wherein M is an integer greater than or equal to 1, and N is a positive integer smaller than or equal to M; and feeding indication information used for indicating the M resources and first-class packet indication information used for indicating that the M resources are divided into the Nfirst-class resource groups back to a first communication node, wherein the resources in the candidate resource set comprise at least one of the following resource types of sending beam resources, sending antenna resources, sending port resources, sending frequency domain resources, sending sequence resources and sending time domain resources. According to the methods and the devices, a problem ofincapability of realizing reasonable and flexible management and scheduling of transmitting beams and / or receiving beams in the correlation technique is solved, and the effects of flexible managementand scheduling of the transmitting beams and / or the receiving beams are realized.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a feedback method, acquisition method and device for group indication information. Background technique [0002] As an important candidate technology for the 5th Generation mobile communication technology (referred to as 5G) communication in the future, high frequency can provide high-speed data communication for future communication with its large bandwidth. However, compared with the low-frequency carrier used by the Long-Term Evolution (LTE for short) in the related technology, the high frequency has its unique transmission characteristics. Its notable feature is that the path loss is very large, which greatly affects its communication distance. At the same time, because the wavelength of high frequency is relatively short, many antenna elements can be placed on a small area, so that multi-antenna technology can be used to form a high-gain narrow beam, which is resistant to ...
