Description

CSI reporting method, device and device

Technical field

The present invention relates to communications technologies, and in particular, to a CSI reporting method, apparatus, and device.

Background technique

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple access techniques capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power). Examples of such multiple access techniques include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, and single carrier frequency division. Address (SC-FDMA) system and Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system.

These multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different wireless devices to communicate at the city, national, regional, and even global levels. An example of an emerging telecommunication standard is Long Term Evolution (LTE/LTE-A). LTE/LTE-A is an enhanced set of Universal Mobile Telecommunications System (UMTS) mobile standards promulgated by the Third Generation Partnership Project (3GPP). LTE/LTE-A is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing cost, improving service, utilizing new spectrum, and using OFDMA on the downlink (DL), on the uplink (UL) uses SC-FDMA and other open standards using Multiple Input Multiple Output (MIMO) antenna technology for better integration. However, as the demand for mobile broadband access continues to increase, there is a need for further improvements in LTE technology. Preferably, these improvements should apply to other multiple access technologies and telecommunications standards that employ these technologies.

At present, the world has begun to study the fifth-generation communication technology (5G), which is a multi-technology communication, which meets a wide range of data and connection services through technology change and innovation. demand. In the 71st meeting of the Radio Access Network (RAN), the Third Generation Partnership Project (3GPP) established a research project (SI) on the 5G new air interface. Among them, according to the division of 5G for vertical scenes, 3GPP mainly relies on enhanced mobile broadband (eMBB) and ultra-reliable low-latency communications (URLLC). Research on new air interface technology in three aspects of massive machine type communications (mMTC).

Specifically, in a Long Term Evolution (LTE) system, an evolved base station (evolved NodeB, hereinafter referred to as "eNB") uses a physical downlink control channel (Physical Downlink Control Channel, referred to as "PDCCH") for a user. A device (User Equipment, referred to as "UE") performs uplink and downlink data scheduling. The minimum time interval for scheduling is one subframe, and the length of one subframe is 1 millisecond. The PDCCH for downlink data scheduling is called downlink allocation (DL_Assignment), and the PDCCH for uplink data scheduling is called uplink grant (UL_Grant).

When the base station performs downlink data scheduling on the UE, the channel state information (CSI, Channel State Information) reported by the UE is required. In the field of wireless communication, channel state information (CSI) is a channel attribute of a communication link, and a user equipment (User Equipment, UE) can report CSI to a base station through channel measurement, so that the base station can perform CSI according to the UE. Downstream scheduling.

The traditional reporting method of the channel state information (CSI) can be divided into periodic CSI reporting and aperiodic reporting, but the above reporting method is less flexible or the overall overhead is still Larger, unable to meet the technical specifications of the next generation wireless communication system. In the 5G new radio system (New Radio, NR), a new CSI reporting method is proposed, that is, the CSI reporting method also includes semi-static CSI reporting. The semi-static CSI reporting refers to the CSI reporting manner performed by the UE after the measurement by the semi-static CSI-RS (Channel State Information-Reference Signal). The semi-static CSI reporting is related to the position of the semi-static CSI-RS in the time-frequency resource block. Compared with the traditional aperiodic CSI reporting and the periodic CSI reporting, the reporting mode is slightly less flexible, but the control signaling overhead is small, and the spectrum utilization rate can be improved in a scenario where the channel variation is not obvious. However, the introduction of the semi-static CSI reporting method brings about conflicts with other methods of CSI reporting.

In the embodiment of the present invention, the terminal device may be referred to as a terminal, a mobile station (Mobile Station, abbreviated as "MS"), a mobile terminal (Mobile Terminal), and a user equipment (User Equipment, referred to as "UE"). The terminal device can communicate with one or more core networks via a Radio Access Network (RAN), for example, the terminal device can be a mobile phone (or "cellular" phone), having The computer or the like of the mobile terminal, for example, the terminal device may also be a portable, pocket-sized, handheld, computer-integrated or in-vehicle mobile device that exchanges voice and/or data with the wireless access network.

In order to facilitate the understanding of the present invention, periodic CSI reporting, aperiodic CSI reporting, and semi-static CSI reporting are first introduced respectively:

(1) Periodic CSI reporting. The base station first sends periodic CSI transmission configuration information to the terminal device, and correspondingly, the terminal device acquires periodic CSI transmission configuration information sent by the base station. Then, the base station sends a trigger indication to the terminal device, and the terminal device receives the trigger indication and performs periodic CSI reporting in the specified period according to the periodic CSI transmission configuration information.

(2) Aperiodic CSI reporting. The base station sends a trigger indication to the terminal device, where the trigger indication includes information for sending an uplink resource of the aperiodic CSI. Correspondingly, the terminal device receives the trigger indication, and performs aperiodic CSI reporting on the base station at the time corresponding to the uplink resource.

(3) Semi-static CSI reporting. The base station first sends a semi-static CSI transmission configuration letter to the terminal device. Accordingly, the terminal device acquires semi-static CSI transmission configuration information sent by the base station. Then, the base station sends a trigger indication to the terminal device, and the terminal device receives the trigger indication and performs semi-static CSI reporting in the specified period according to the semi-static CSI transmission configuration information.

Under the existing technical conditions, there is no conflict between semi-static CSI reporting and periodic CSI reporting, semi-static CSI reporting and aperiodic CSI reporting conflicts, and semi-static CSI reporting conflicts with periodic CSI reporting and aperiodic CSI reporting. The solution when a conflict occurs.

In order to solve the above problem, the embodiment of the present invention provides a CSI reporting method, as shown in FIG. 1 , including the following steps:

Step 110: The base station sends a first trigger indication and a second trigger indication to the terminal device. Correspondingly, the terminal device receives the first trigger indication and the second trigger indication sent by the base station. The first trigger indication is used to indicate that the terminal device performs semi-static CSI reporting at the first moment, and the second trigger indication is used to indicate that the terminal device performs non-semi-static CSI reporting at the second moment.

In the embodiment of the present invention, the first trigger indication is carried in Downlink Control Information (DCI) format 0/4, or in an uplink grant in a Random Access Response (RAR), or randomly. In the downlink allocation in the access response, the second trigger indication is carried in the downlink control information DCI format 0/4, or the uplink grant in the random access response, or the downlink assignment in the random access response.

In some possible implementation manners, the first trigger indication may be any one or a combination of bits, scrambling codes, or other time-frequency resource information. Similarly, the second trigger indication may be any one or a combination of bits, scrambling codes or other time-frequency resource information.

In a specific embodiment, the bit may be a DCI format 0/4, an uplink grant of the RAR, or a bit in a corresponding field in the downlink assignment of the RAR. When this bit is set to "0" or "1", Used to indicate the CSI report. For example, there is a 1-bit information field in the DCI Format0. When the 1-bit information value of the information field is 0, it indicates that the CSI report is not triggered. When the 1-bit information value of the information field is 1, it indicates that the CSI report is triggered.

In a specific embodiment, the scrambling code may be an SPS Cell Radio Network Temporary Identifier (SPS C-RNTI), and may be a Cell Radio Network Temporary Identifier (C-RNTI). It can also be other scrambling codes.

In the embodiment of the present invention, the CSI may be any one or a combination of a Rank Indicator (RI), a Precoding Matrix Indicator (PMI), and a Channel Quality Indicator (CQI). .

In the embodiment of the present invention, the semi-static CSI reporting may be performed by using a Physical Uplink Shared Channel (PUSCH) (with uplink data transmission) or by a Physical Uplink Control Channel (PUCCH). Send (when no uplink data is sent). The non-semi-static CSI report may be any one of a periodic CSI report, an aperiodic CSI report, a periodic CSI report, and an aperiodic CSI report, which is not specifically limited by the present invention. The periodic CSI may be sent through the PUSCH or through the PUCCH, and the aperiodic CSI is sent through the PUSCH.

130: The terminal device determines, according to the first trigger indication and the second trigger indication, whether the first moment and the second moment collide.

150: If the terminal device determines that the first moment collides with the second moment, the terminal device determines whether the terminal device supports the carrier aggregation technology.

In an embodiment of the invention, the carrier aggregation technique is an operation on multiple carriers. Carrier aggregation can also be referred to as multi-carrier operation. A carrier can refer to a range of frequencies used for communication and can be associated with certain characteristics. For example, a carrier may be associated with system information and/or control information describing operations on the carrier. A carrier may also be referred to as a component carrier (CC), a frequency channel, a cell, and the like. A frequency band can include one or more carriers. Illustratively, each carrier can cover up to 20 MHz. The terminal device can be configured with up to 5 carriers in one or two frequency bands. The terminal device may include multiple receivers to simultaneously receive multiple downlink signals at different frequencies. These multiple downlink signals may be transmitted by one or more base stations on multiple carriers at different frequencies for carrier aggregation. Each receiver may receive one or more downlink signals transmitted to the terminal device on one or more carriers. A terminal device operating in a carrier aggregation scenario is configured to aggregate certain functions of multiple carriers, such as control and feedback functions, on the same carrier, which may be referred to as a primary carrier or a primary component carrier. The remaining carriers that rely on the primary carrier support are referred to as associated secondary or secondary component carriers. The primary carrier is sent by the primary cell. The secondary carrier is sent by the secondary cell. The primary carrier includes a PUCCH and a PUSCH, and the secondary carrier includes only a PUSCH. It should be specially noted that in the LAA authorized secondary access system, the primary carrier may be an authorized spectrum, and the secondary carrier may be an unlicensed spectrum (eg, Such as WiFi).

If the terminal device determines that the terminal device supports the carrier aggregation technology, the terminal device performs non-semi-static CSI reporting to the base station by using the first carrier, and performs semi-static CSI reporting to the base station by using the second carrier. Correspondingly, the base station receives the non-semi-static CSI report by the terminal device by using the first carrier, and receives the semi-static CSI report by the terminal device by using the second carrier.

Alternatively, the terminal device may perform periodicity through the PUSCH of the secondary carrier. The CSI reports the semi-static CSI reporting through the PUCCH or the PUSCH of the primary carrier.

When the non-semi-static CSI is reported as a non-periodic CSI, the terminal device may perform the aperiodic CSI reporting on the PUSCH of the primary carrier, and perform the semi-static CSI reporting on the PUSCH of the secondary carrier. Alternatively, the terminal device may perform the half through the PUSCH of the primary carrier. The static CSI is reported, and the aperiodic CSI is reported on the PUSCH of the secondary carrier.

The PUSCH performs the semi-static CSI reporting on the PUSCH of the primary carrier, and performs the periodic CSI reporting on the PUSCH of the primary secondary carrier, and performs the semi-static CSI reporting on the PUSCH of the second secondary carrier; or The terminal device may perform the semi-static CSI reporting on the PUSCH or the PUCCH of the primary carrier, perform the aperiodic CSI reporting on the PUSCH of the first secondary carrier, and perform the periodic CSI reporting on the PUSCH of the second secondary carrier.
