Embodiment 1

[0102] Embodiment 1 of this application mainly describes the configuration and indication method of the fixed collocation of CMR resource set and IMR resource set. The core of this embodiment 1 lies in:

[0103] The network device configures the corresponding relationship between CMR resource set and IMR resource set, and CMR resource set corresponds to IMR resource set;

[0104] The network device completes the joint indication of the measurement resources of the channel measurement hypothesis and the interference measurement hypothesis through the indication of the CMR resource set.

[0105] Such as figure 2 As shown, in the first embodiment, the CMR resource set specifically includes multiple, and the IMR resource set specifically includes multiple,

[0106] Wherein, the network side indicates Resource setting 0 to be used for channel measurement through link0, and indicates Resource setting 1 to be used for interference measurement through link1.

[0107] Resource setti...

Embodiment 2

[0134] Embodiment 2 of the present application mainly describes the configuration and indication method for the flexible collocation of CMR resource set and IMR resource set. The main core of Embodiment 2 lies in:

[0135] There is no predetermined correspondence between the CMR resource set configured by the network device and the IMR resource set;

[0136] The network device completes the joint indication of the measurement resources of the channel measurement hypothesis and the interference measurement hypothesis through the indication of {CMR resource set, IMR resource set}.

[0137] Specifically, such as Figure 4 Shown:

[0138] Resource setting 0 is used for channel measurement, which contains S CMR ≥1 CSI-RS resource set, that is, CMR resource set, respectively set0-1, set0-2, set0-3; each CSI-RS resource set contains one or more NZP CSI-RS resource (NZP CMR) .

[0139]Resource setting 1 is used for interference measurement, which contains S IMR ≥1 CSI-RS resource...

Embodiment 3

[0160] Embodiment 3 of this application mainly describes the configuration and indication method based on predefined channel and interference assumption conditions. The main core of Embodiment 3 lies in:

[0161] Network equipment configures the matching relationship between CMR resource set and IMR resource set;

[0162] The network device completes the joint indication of the measurement resources of the channel measurement hypothesis and the interference measurement hypothesis through the indication of {Measurement hypothesis}.

[0163] Such as Figure 4 As shown, the network device configures the CSI-RS resource set in Resource setting 0 and the CSI-RS resource set in Resource setting 1 through the first signaling to form several channel and interference measurement assumptions. Each channel and interference measurement assumption corresponds to a set of channel measurement resources (including one or more CMRs) and a set of interference measurement resources (including o...

Abstract

The invention aims at configuration and indication problems related to CSI-RS resource, and designs corresponding configuration and indication technologies. The technologies comprise that network equipment configures the CSI-RS resource into a resource set for channel measurement and a resource set for interference measurement, and provides various corresponding modes of the resource set for channel measurement and the resource set for interference measurement; in another implementation mode, the network equipment aims at one CSI-RS resource set, and configures the resources in the set to comprise both the resource for channel measurement and the resource for interference measurement; and the network equipment transmits indication information for measuring reference signals to a terminal,so as to indicate the resource set for channel measurement or which resource is used for channel measurement and which resource is used for interference measurement in one set. Thus, flexible and diversified configuration for the CSI-RS resource is conducted by the network equipment, moreover, indication overhead is reduced as much as possible, and requirements of channel measurement and interference measurement of a multi-user terminal under an NR system can be satisfied.

Description

technical field [0001] The present application relates to the communication field, and in particular to an indication method for measuring channel state information reference signals, a method for measuring channel state information reference signals, network equipment and terminals. Background technique [0002] In the multi-base station coordinated multi-point transmission scenario, the network side needs to configure multiple channels and interference measurement resources, and the terminal device side needs to measure and feed back channel state information (Channel State Information, CSI) under one or more interference situations, so that The network side reasonably determines the transmission scheme of the multi-base station coordinated multi-point transmission, the corresponding link adaptive configuration, and the scheduling strategy according to various CSIs. [0003] In Long Term Evolution (LTE), a user equipment (user equipment, UE) can be configured with one or m...
