REPORTING METHOD, EQUIPMENT, AND MEDIUM

TECHNICAL FIELD

This disclosure relates to the field of communication technology, in particular to a reporting method, an equipment, and a medium.

BACKGROUND

Channel state information (CSI) is a channel attribute of a wireless communication link. It describes a fading factor of a signal in each transmission path, that is, a value of each element in a channel gain matrix H, such as signal scattering, multi-path fading or shadowing fading, power decay of distance, and other information.

The 3rd generation partnership project (3GPP) new radio (NR) R15/R16 protocol supports beam measurement and reporting, where the beam is characterized by a reference signal. For non-beam group-based beam measurement and CSI report, the CSI report may include one or more reference signal indexes and corresponding measurement results Ll-reference signal received power (RSRP) values or LI-signal-to-interference-plus-noise ratio (SINR) values. R15/R16 protocol also supports beam group-based CSI measurement and reporting, but one CSI report only contains one beam group, and one CSI only associates with one resource set.

In R17, beam enhancement in multi-transmission and reception point (TRP) scenarios is standardizing to further optimize and improve the beam management mechanism. However, there is no specific technical scheme for the specific content of the CSI report.

DETAILED DESCRIPTION

Exemplary embodiments, examples of which are shown in the drawings, will be explained in detail herein. When the following description relates to the drawings, the same numerals in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary implementations are not representative of all implementations consistent with the disclosure. Rather, they are only examples of devices and methods consistent with some aspects of the disclosure as detailed in the appended claims.

It should be noted that, as used herein, the terms “include,” “contain,” or any other variation thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or device including a set of elements includes not only those elements but also other elements not explicitly listed, or also elements inherent to such a process, method, article, or device. Without further limitation, an element defined by the phrase “including an . . . ” does not preclude the existence of another identical element in the process, method, article, or device in which the element is included. Furthermore, components, features, elements having the same name in different embodiments of the disclosure may have the same meaning or different meanings, the specific meanings of which are to be determined by their interpretation in the specific embodiment or further in conjunction with the context in the specific embodiment.

It should be understood that although the terms “first”, “second”, “third”, etc. may be used herein to describe various kinds of information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope herein, the first information may also be referred to as the second information and similarly the second information may also be referred to as the first information. Depending on the context, the word “if” as used herein can be interpreted as “when” or “while” or “in response to determining”. Furthermore, as used herein, the singular forms “a”, “an”, and “the” are intended to include plural forms as well, unless the context dictates to the contrary. It should be further understood that the terms “including” and “containing” indicate the existence of the described features, steps, operations, elements, assemblies, items, categories, and/or groups, but do not exclude the existence, occurrence, or addition of one or more other features, steps, operations, elements, assemblies, items, categories, and/or groups. The terms “or” and “and/or” as used herein are construed as inclusive or mean any one or any combination. Thus, “A, B, or C” or “A, B, and/or C” means “any of the following: A: B: C: A and B: A and C: B and C: A. B, and C”. Exceptions to this definition occur only when combinations of elements, functions, steps, or operations are inherently mutually exclusive in some way.

It should be understood that although the various steps in the flow chart in the embodiments of the disclosure are shown sequentially as indicated by the arrows, these steps are not necessarily performed sequentially in the order indicated by the arrows. Unless expressly stated herein, the execution of these steps is not strictly sequential and may be performed in other orders. Furthermore, at least a portion of the steps in the figure may include multiple sub-steps or stages, which are not necessarily completed at the same time, but may be executed at different times, and the execution order is not necessarily sequential, but may be executed in turn or alternately with other steps or at least a portion of sub-steps or stages of other steps.

It should be noted that, herein, marks of steps such as 110 and 120 are adopted, which are intended to express the corresponding contents more clearly and briefly, and do not constitute a substantial limitation in order. In the specific implementation, those skilled in the art may perform 120 first and then 110, and these should be within the scope of protection of the disclosure.

In the subsequent description, suffixes such as “module”, “component”, or “unit” used to denote elements are used only for the benefit of the description of the disclosure and have no specific meaning per se. Therefore, “module”, “component”, or “unit” can be used in a mixed way.

The CSI report may include measurement results for the N beam pairs/groups, where the N beam pairs/groups include a first beam pair/group and a second beam pair/group, and the second beam pair/group is any of the N beam pairs/groups other than the first beam pair/group. For example, when N is 3, the N beam pairs/groups can include beam pair/group 1, beam pair/group 2, and beam pair/group3. If the first beam pair/group is beam pair/group 1, the second beam pair/group can be any one of beam pair/group 2 and beam pair/group3.

It should be noted that the measurement result for the first beam pair/group may include one of the index of the first resource set and the index of the second resource set. In practice, whether the index of the first resource set or the index of the second resource set can be determined by the network device or the terminal device.

Optionally, the first reference signal and the second reference signal are from different resource sets: the third reference signal and the fourth reference signal are from different resource sets.

For example, assuming that N included in the CSI report configuration information is 2, and the CSI report is associated with two resource sets: resource set 1 {resource corresponding to resource index 10, resource corresponding to resource index 11, resource corresponding to resource index 12, resource corresponding to resource index 13}, and resource set 2 {resource corresponding to resource index 20, resource corresponding to resource index 21, resource corresponding to resource index 22, resource corresponding to resource index 23}.

Two beams or reference signals included in beam pair/group 2 (corresponding to the second beam pair/group) contained in the CSI report are from the resource corresponding to resource index 11 in resource set 1 and the resource corresponding to resource index 23 in resource set 2, respectively. The value of LI-RSRP or LI-SINR corresponding to the resource corresponding to resource index 10 in resource set 1 can be the maximum value, the minimum value, or any value. The terminal device may regard the LI-RSRP or LI-SINR corresponding to the resource corresponding to resource index 10 in resource set 1 as the reference LI-RSRP or reference LI-SINR.

The fifth reference signal and the seventh reference signal are from the same resource set: the sixth reference signal and the eighth reference signal are from the same resource set.

Optionally, the fifth reference signal and the sixth reference signal are from different resource sets: the seventh reference signal and the eighth reference signal are from different resource sets.

For example, assuming that M included in the CSI report configuration information is 4, K determined by the terminal device is 2, and the CSI report is associated with two resource sets: resource set 1 {resource corresponding to resource index 10, resource corresponding to resource index 11, resource corresponding to resource index 12, resource corresponding to resource index 13}, and resource set 2 {resource corresponding to resource index 20, resource corresponding to resource index 21, resource corresponding to resource index 22, resource corresponding to resource index 23}. Through measurement, the terminal obtains the CSI report. Two beams or reference signals included in beam pair/group 1 (corresponding to the first beam pair/group) contained in the CSI report are from the resource corresponding to resource index 10 in resource set 1 and the resource corresponding to resource index 22 in resource set 2, respectively. Two beams or reference signals included in beam pair/group 2 (corresponding to the second beam pair/group) contained in the CSI report are from the resource corresponding to resource index 11 in resource set 1 and the resource corresponding to resource index 23 in resource set 2, respectively. The value of L1-RSRP or LI-SINR corresponding to the resource corresponding to resource index 10 in resource set I can be the maximum value, the minimum value, or any value. The terminal device may regard the LI-RSRP or LI-SINR corresponding to the resource corresponding to resource index 10 in resource set 1 as the reference LI-RSRP or reference LI-SINR. Assume that beam pair/group 1 is characterized by reference signal 10 and reference signal 22, and beam pair/group 2 is characterized by reference signal 11 and reference signal 23. The CSI reported by the terminal device may include the following information: the first part and the second part.

The first part: number K, index of resource set 1, resource index 10, RSRP value 1: resource index 22, differential RSRP value 1.

(index of resource set 1, resource index 10. RSRP value 1: resource index 22, differential RSRP value 1) corresponds to the measurement result for beam pair/group 1: (resource index 11, differential RSRP value 2: resource index 23, differential RSRP value 3), corresponds to the measurement result for beam pair/group 2.

RSRP value 1 is a reference RSRP value. Differential RSRP value 1 is a differential RSRP value of the RSRP value of reference signal 22 in beam pair/group 1 with respect to RSRP value 1. Differential RSRP value 2 is a differential RSRP value of the RSRP value of reference signal 11 in beam pair/group 2 with respect to RSRP value 1, and so on.

230, report the CSI report according to the network configuration information, where the CSI report includes measurement results for the one or more beam pairs/groups.

Through the above operations, after the terminal device determines the CSI report, it can report the CSI report to the network device.

In the scheme of the disclosure, the CSI report can include the measurement results for the one or more beam pairs/groups and one CSI report can be associated with one or more resource sets. Compared with the related art, one CSI report can include measurement results of more beam pairs/groups and be associated with more resource sets. With the method, it is beneficial to report the measurement results for the one or more beam pairs/groups. With the method, it is also beneficial to further improve the beam management mechanism of the multi-TRP transmission and to effectively support the multi-TRP transmission. With the method, the terminal can be supported to dynamically decide the number of beam pairs/groups contained in one CSI report, thereby realizing understanding in consistency of the terminal and the network, effectively reducing the resource overhead and improving the network performance.
