Embodiment 1

[0266] This embodiment describes how multiple CSI-RS resources share transmission parameters.

[0267] Refer to the current CSI-RS structure of NR, such as figure 2 As shown, a reference signal set (RS setting) includes S CSI-RS resource sets (resource sets) (corresponding to the above-mentioned measurement reference signal resource sets), and each CSI-RS resource set includes Ks CSI-RS resources ( resource). Wherein, both S and Ks are positive integers. Figure 5 Different measurement reference signal resource sets correspond to different transmission beams.

[0268] The first implementation mode in which multiple CSI-RS resources share transmission parameters is that the transmission parameters are configured in the configuration information of the RS setting, and all CSI-RS resources included in the RS setting share the transmission parameters, so that in the configuration of the CSI-RSresource The configuration of the above transmission parameters may not be included i...

Embodiment 2

[0279] This embodiment describes the transmission parameters shared by multiple CSI-RS resources.

[0280] The first shared parameter is time unit offset (or called time unit offset, time unit offset). For example, multiple CSI-RS resources that occupy the same time slot will share cycle configuration parameters. At this time, multiple CSI-RS resources The time slot parameters corresponding to the RS resources are the same. Wherein, the multiple CSI-RS resources may be sent periodically or half-periodly. For example, the transmission period of the CSI-RS resource is T, and the time unit offset is ΔT. At this time, the set of time slots occupied by the CSI-RS resource is {n, mod(n+ΔT, T)=0}, where n is An integer greater than or equal to 0, ΔT is an integer less than T, where n, ΔT, and T have the same unit, which is a time unit, such as a slot, or a time-domain OFDM symbol, etc. .

[0281] The second shared parameter is the time domain symbol position, which divides the CSI...

Embodiment 3

[0294] This embodiment describes the configuration of the time domain parameters in the CSI-RS configuration information.

[0295] In the first type of configuration information in this embodiment, the time-domain parameters may include at least one of the following: time-domain symbol positions of various subcarrier spacings, and number of various time-domain symbols. Such as Figure 13 As shown, the subcarrier spacing transmitted by the CSI-RS is larger than the time domain symbols corresponding to other signals, and multiple time domain symbols with large subcarrier spacing correspond to one time domain symbol with small subcarrier spacing. Such as Figure 13 As shown, a time-domain symbol with the first small sub-carrier spacing includes 4 time-domain symbols with a large sub-carrier spacing. At this time, at least one of the position and number of the first time domain symbols occupied by the CSI-RS resources and at least one of the position and number of time domain sy...

Abstract

The invention discloses an information configuration method and device. The information configuration method comprises the steps of transmitting information carrying transmission parameters to a second communication node, wherein the transmission parameters are shared by M resources; or conventionalizing the transmission parameters shared by the M resources with the second communication node, wherein M is a natural number which is greater than 1, and the resources are one or more types of the following resources: measurement reference signal resources, reporting resources and reference signalresources. In addition, a time-frequency resource area is set, and resources falling in the same time-frequency area are enabled in a quasi co-location relation, so that the setting of a QCL relationbetween the resources is simplified. On the other hand, considering the transmission of a measurement reference signal of the fractional bandwidth in the NR (New Radio), the design of a measurement reference signal pattern can occupy resources occupied by other signals.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information configuration method and device. Background technique [0002] In the discussion of NR (New Radio, new air interface), it is necessary to support high-frequency communication, and a notable feature of high-frequency communication is the need for beam-based transmission. At present, CSI-RS (Channel State Information Reference Signal, Channel State Information Reference Signal) can be used for CSI (Channel State Information, Channel State Information) acquisition similar to low frequency, and can also be used for beam management; when CSI-RS is used for beam management When training, especially high-frequency hybrid beam management, a significant difference from low-frequency beam training is that multiple beams corresponding to a radio frequency link need to be sent in time division, while low-frequency digital beams can generate many beams at a time....
