Detailed Description

Currently, wireless communication systems have evolved and evolved from the fourth generation of Long Term Evolution (LTE), Long Term Evolution Advanced (LTE-a), to the fifth generation of New Radio Access Technology (NR). In communication systems such as NR and LTE, in order to better transmit Information, a base station or a user terminal needs to calculate Channel State Information (CSI), where the CSI includes but is not limited to: a Channel Quality Indication (CQI), a Precoding Matrix Indication (PMI), a Rank Indication (RI), a Channel state information reference pilot resource Indication (CRI), and a Layer Indication (LI). In order to calculate CSI, a base station or a user terminal is required to transmit a Reference Signal (RS), which includes but is not limited to: a Channel-State Information reference signal (CSI-RS), a Channel-State Information Interference Measurement signal (CSI-IM), a Sounding Reference Signal (SRS); the CSI-RS comprises Zero Power CSI-RS (Zero Power CSI-RS, ZP CSI-RS) and Non-Zero Power CSI-RS (Non-Zero Power CSI-RS, NZP CSI-RS); the NZP CSI-RS can be used to measure channel or interference, while CSI-IM is typically used to measure interference and SRS is typically used to measure channel. The reference signals, CSI-RS, SRS, CSI-IM, etc., may include time domain characteristics when transmitted, wherein the time domain characteristics include, but are not limited to: aperiodic characteristics (e.g., aperiodic CSI-RS, A-CSI-RS), periodic characteristics (e.g., periodic CSI-RS, P-CSI-RS), semi-persistent characteristics (e.g., semi-persistent CSI-RS, SP-CSI-RS), respectively, indicate that the transmitted reference signal is non-periodically transmitted, or semi-persistently transmitted.

In order to transmit CSI information, the user terminal needs to use a Physical Uplink Control Channel (PUCCH) and/or a Physical Uplink Shared Channel (PUSCH) of an Uplink. The CSI information is also called CSI report, and the base station configures a resource (PUSCH or PUCCH) for transmitting CSI and configures transmission content (including but not limited to one of the following parameters, CRI, RI, PMI, CQI, and the like) of CSI through high-layer signaling, where the transmission content and transmission time of CSI and the like form a CSI report (CSI report), where the CSI report may be transmitted on PUSCH or PUCCH, and the CSI report also includes time domain characteristics, including periodic CSI report (periodic CSI report, P-CSI), aperiodic CSI report (AP-CSI), and semi-persistent CSI report (semi-persistent CSI report, SP-CSI). Generally, the number of bits for P-CSI transmission is relatively small and transmitted on PUCCH, while the number of bits for a-CSI transmission is large and transmitted on PUSCH, and SP-CSI can be transmitted on PUSCH or on PUCCH. The P-CSI transmitted based on the PUCCH is generally configured by a higher layer signaling (Radio Resource Control, RRC), the SP-CSI transmitted based on the PUCCH is also configured or activated by a higher layer signaling (RRC and/or MAC CE, where MAC CE is a Media Access Control Element, a Control unit for Media Access Control), and the SP-CSI or a-CSI transmitted based on the PUSCH is triggered by a Physical layer signaling (Downlink Control information, DCI), and the DCI is generally transmitted on a Physical Downlink Control Channel (PDCCH).

The embodiment of the application provides a mobile communication network (including but not limited to a 5G mobile communication network), and the network architecture of the network can comprise a network side device (such as a base station) and a terminal. In this embodiment, an information transmission method capable of operating on the network architecture is provided, and it should be noted that an operating environment of the information transmission method provided in this embodiment is not limited to the network architecture.

It should be added that, in the embodiment of the present application, the communication node includes a first communication node and/or a second communication node, where the first communication node may be a base station side device in downlink and the second communication node may be a terminal side device, and of course, the first communication node may be a terminal side device and the second communication node may also be a base station side device in uplink. In case both communication nodes are device-to-device communication, both the first communication node and the second communication node may be base stations or terminals.

In the wireless communication system, a base station configures N CSI reports (CSI report) which need to be fed back to the base station to a terminal through high-layer signaling and/or physical-layer signaling, each CSI report has an index value (ID), called CSI report ID, and the terminal can calculate M CSI reports in the N CSI reports according to the own calculation capability or processing capability and the requirement of the base station.

For simplicity, Numerology and subcarrier spacing in the embodiments of the present application may be replaced with each other, and the equivalent concept, that is, subcarrier spacing may be replaced where Numerology is used, reference subcarrier spacing may be replaced where reference Numerology is used, and conversely, Numerology may be replaced where subcarrier spacing is used, and reference Numerology may be replaced where reference subcarrier spacing is used. The uplink resource used for transmitting the nth CSI report comprises PUCCH and/or PUSCH; the reference signal corresponding to the nth CSI report includes at least one NZP CSI-RS for measuring the channel, and may also include at least one CSI-IM for measuring interference, and in some cases, may also include at least one NZP CSI-RS2 for measuring interference. Optionally, the base station or the terminal takes Numerology or subcarrier spacing corresponding to all NZP CSI-RSs for measuring channels corresponding to the nth CSI report, Numerology or subcarrier spacing corresponding to all NZP CSI-RSs for measuring interference (if present), minimum value or maximum value of Numerology or subcarrier spacing corresponding to all CSI-IMs for measuring interference (if present), or system-agreed value as Numerology or subcarrier spacing μ corresponding to the reference signal _n,2 .

Wherein N is 1, …, N, N and M are positive integers, and N is greater than or equal to M. M is less than or equal to the number of the CSI processing units CPU which are not occupied by the terminal. Numerology represents a characteristic of the frame structure that characterizes the relationship between the subcarrier spacing, cyclic prefix, number of symbols, etc. of the frame and Numerology. For example in NR, Numerology and subcarrier spacing/cyclic prefix relationships are defined as shown in table 1:

			0	15	Normal
1	30	Normal
			2	60	Normal,Extended

the first CSI calculation delay value Z1 indicates that the terminal needs to demodulate the PDCCH to perform channel and interference measurement when calculating the CSI, and the minimum time of CSI calculation is obtained. The first CSI calculation delay value Z1 is divided into a Low latency CSI Class and a High CSI latency Class according to the difference of port number of CSI-RS, types of codebooks and the like. And the second CSI calculation delay value Z2 represents the minimum time for the terminal to perform channel and interference measurement and CSI calculation when calculating CSI. That is, Z2 is the time of Z1 minus demodulation of PDCCH.

for the CSI processing capability type A, determining the priority of N CSI reports through a first rule; selecting M CSI reports from high to low according to the priority of the N CSI reports;

or, for the CSI processing capability type B, determining the priority of the N CSI reports through a first rule; selecting M CSI reports from high to low according to the priority of the N CSI reports;

under the condition that the CSI calculation delay values Z in two or more CSI reports are the same, determining the priority of the CSI report with the same CSI calculation delay value Z according to the CSI report index value; the priority of the CSI report with the small CSI report index value is higher than that of the CSI report with the large CSI report index value;

For example: determining the priority of two CSI reports according to a first rule without loss of generality, and assuming that a CSI report 1 and a CSI report 2 exist; comparing the corresponding CSI processing delay values Z of the two CSI reports;

if the CSI processing delay value Z (for example, Z is 9) corresponding to CSI report 1 is smaller than the CSI processing delay Z (for example, Z is 11) corresponding to CSI report 2, the priority of CSI report 1 is high;

if the CSI processing delay value Z (for example, Z equal to 11) corresponding to CSI report 1 is smaller than the CSI processing delay Z (for example, Z equal to 8) corresponding to CSI report 2, the priority of CSI report 2 is high;

if the CSI processing delay values Z corresponding to the two CSI reports are the same, comparing the corresponding CSI report IDs of the two CSI reports;

if the CSI report ID (for example, ID ═ 1) corresponding to CSI report 1 is smaller than the CSI report ID (for example, ID ═ 2) corresponding to CSI report 2, then the priority of CSI report 1 is high;

if the CSI report ID (for example, ID ═ 2) corresponding to CSI report 1 is greater than the CSI report ID (for example, ID ═ 1) corresponding to CSI report 2, then the priority of CSI report 2 is higher;

if the CSI report IDs corresponding to the two CSI reports are the same, comparing the time domain characteristics of the two CSI reports; the priority of the aperiodic CSI report is higher than that of the semi-continuous CSI report, and the priority of the semi-continuous CSI report is higher than that of the periodic CSI report.

Certainly, under the condition that the CSI processing delay values Z corresponding to the two CSI reports are the same, the time domain characteristics of the CSI reports may be compared first, and the CSI report with the higher priority of the time domain characteristics has the higher priority; under the condition that the time domain characteristics are the same, the CSI report IDs corresponding to the CSI reports can be compared, and the CSI report with small CSI report IDs has high priority. The reference Numerology corresponding CSI calculation delay value comprises a first CSI calculation delay value Z1 and/or a second CSI calculation delay value Z2.

Optionally, when the nth CSI report is a CSI report satisfying the first condition, the delay value during CSI calculation of the nth CSI report is not greater than the set threshold value Z0; wherein N is 1, …, N and Z are positive integers.
