Embodiment 1

[0054] Provides an indication of a location of resources in the method of the present embodiment, figure 2 The method of indicating the resource location is an embodiment of the present invention, a flow chart, such as figure 2 As shown, the process includes the following steps:

[0055] Step S202, the first type node transmits resource location information to the second class node, the resource location information indicating the location of at least the frequency domain resource; wherein the frequency domain comprises at least one of the following positions: a first position of the frequency domain resource , a frequency domain location of the second resource; resource of the first or the second resources comprise at least one of the following: bandwidth part BWP, PDSCH physical downlink shared channel resources occupied by the common set of control resources.

[0056] Alternatively, the step of performing a first main body of the node may be a base station type, such as concret...

Embodiment 2

[0105] This alternative embodiment describes the frequency domain position of the first resource using an offset with respect to the reference point, using an offset relative to the first resource frequency domain.

[0106] like Figure 4Gives SS block, PDSCH and Common CORESET position NR the frequency domain carrier, wherein, k1, k2 and k3 respectively SS block, PDSCH and the center frequency of Common CORESET corresponding to subcarrier number, the base station may use Common CORESET PDCCH scheduling a PDSCH resources occupied bearer. A first resource to the resource occupied by the PDSCH as an example, Common CORESET second resource to an example, the reference point to the center of SS block as an example. Examples base station indicates to the terminal of the present embodiment PDSCH center frequency offset with respect to the center frequency shift and the SS block PDSCH bandwidth point, and the center frequency of Common CORESET relative to the center frequency of the PDSCH...

Embodiment 3

[0117] The present alternative embodiment described with respect to the frequency domain using the offset indicates the position of the first resource on the frequency domain reference point, the second node is calculated according to predefined rules frequency domain position of the second resource.

[0118] like Figure 5 Gives SS block, BWP and Common CORESET position NR the frequency domain carrier. In a first resource BWP, for example, Common CORESET second resource to an example, the reference point to the center of SS block as an example. In the present embodiment, the base station indicates to the terminal of the center frequency BWP SS block with respect to the bandwidth of the center frequency offset and the BWP, CommonCORESET bandwidth indication comprises a relatively specific content subcarrier number, and right and left offset indicates a bandwidth, as shown in table 5, wherein - denotes the entry does not exist.

[0119] Wherein the center BWP frequency point relativ...

Abstract

The invention provides a method and device for indicating and receiving resource positions. Wherein, the method includes: the node of the first type sends resource location information to the node of the second type, and the resource location information is at least used to indicate the frequency domain location of the resource; wherein, the frequency domain location includes at least one of the following: the first resource The frequency domain position of the second resource, the frequency domain position of the second resource; the first resource or the second resource includes at least one of the following: a bandwidth part BWP, a resource occupied by a physical downlink shared channel PDSCH, and a common control resource set. The present invention solves the problem that the base station cannot indicate the resource positions of BWP, PDSCH and common CORESET(s) in the related art, and achieves the technical effect that the resource positions can be effectively indicated.

Description

Technical field [0001] The present invention relates to communication field, specifically, it relates to a resource indication locations, receiving method and apparatus. Background technique [0002] In the future wireless communication systems (e.g., 5G), the communication will be used, for example 28GHz, 45GHz, etc. higher than the fourth-generation communication system, a carrier frequency used by the carrier frequency, 5G new radio access technology (Radio AccessTechnology, referred to as RAT) system operating frequency band potential reach 100GHz. Since the high-frequency communication with a carrier frequency corresponding to a shorter wavelength, it is possible to ensure that the antenna can accommodate more elements per unit area, the more the antenna elements means that the method of beamforming may be used to increase the antenna gain, so as to ensure high frequency communication coverage performance. [0003] After beamforming method, transmitter may emit energy concen...
