Description

[Technical Field]

[0001] Embodiments of this disclosure generally relate to the field of telecommunications, and more particularly to communication methods, devices, and computer storage media for channel state information (CSI). [Background technology]

[0002] Several techniques have been proposed to improve communication performance. For example, multi-input multi-output (MIMO) has been proposed. MIMO includes features that facilitate the use of multiple antenna elements at base stations for both the sub-6GHz and over-6GHz frequency bands. In this scenario, multiple antennas in the transmitter and / or receiver can be used to achieve array and diversity gain instead of capacitive gain. In radio communications, channel state information (CSI) is the known channel characteristics of a communication link. This information describes how a signal propagates from the transmitter to the receiver and represents, for example, the combined effects of scattering, fading, and power attenuation with distance. The method is called channel estimation. CSI allows transmission to adapt to the current channel state, which is important for achieving reliable communication at high data rates in multi-antenna systems. Therefore, CSI enhancement is worth studying. [Overview of the Initiative]

[0025] The principles and implementation forms of this disclosure will be described in detail below with reference to the drawings.

[0026] Figure 1 shows a schematic diagram of an exemplary communication network 100 in which several embodiments of the present disclosure may be implemented. As shown in Figure 1, the communication network 100 may include terminal devices 110 and network devices 120. Network device 120 may provide a cell 102 to serve one or more terminal devices. In this example, terminal device 110 is located in cell 102 and is served by network device 120. In the example of Figure 1, terminal device 110 may be an UE, and network device 120 may be a base station serving the UE. The serving area of ​​network device 120 may be referred to as cell 102.

[0027] For example, network device 120 may consist of at least one of four TRP / panels 130-1, 130-2, 130-3, and 130-4 (collectively referred to as TRP130, or individually as TRP130). It should be understood that the number of network devices, terminal devices, and TRPs shown in Figure 1 are illustrative and not limiting to this disclosure. Network 100 may include any appropriate number of devices adapted to implement embodiments of this disclosure. It should be understood that one or more additional devices may be located in cell 102, and one or more additional cells may be deployed in the communication environment 100, although these are not shown. Note that although shown as a network device, network device 120 may be a device other than a network device. Terminal device 110, although shown as a terminal device, may be a device other than a terminal device. The term "TRP" refers to an antenna array (having one or more antenna elements) available to network devices located at a particular geographical location. For example, a network device may be coupled with multiple TRPs at different geographical locations to achieve better coverage. In another example, a network device may be implemented with multiple panels or groups of antenna ports / elements at the same geographical location. It should be understood that TRPs are sometimes referred to as "panels" and can also refer to antenna arrays or groups of antennas (having one or more antenna elements).

[0028] In the following, for illustrative purposes, several exemplary embodiments are described in which the terminal device 110 operates as a UE and the network device 120 operates as a base station. However, in some exemplary embodiments, the operations described in relation to the terminal device may be implemented in the network device or other devices, and the operations described in relation to the network device may be implemented in the terminal device or other devices.

[0029] In some exemplary embodiments, when terminal device 110 is a terminal device and network device 120 is a network device, the link from network device 120 to terminal device 110 is referred to as a downlink (DL), and the link from terminal device 110 to network device 120 is referred to as an uplink (UL). In DL, network device 120 is a transmitting (TX) device (or transmitter), and terminal device 110 is a receiving (RX) device (or receiver). In UL, terminal device 110 is a TX device (or transmitter), and network device 120 is an RX device (or receiver). In some embodiments, terminal device 110 and network device 120 may communicate with each other via a channel, such as a wireless communication channel on an air interface (e.g., a Uu interface). Wireless communication channels may include the physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), physical random access channel (PRACH), physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), and physical broadcast channel (PBCH). Naturally, any other suitable channel is also possible.

Embodiments of this disclosure may be implemented in accordance with any generation of communication protocol that is currently known or will be developed in the future. Examples of communication protocols include, but are not limited to, first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G) communication protocols, 5.5G, 5G-Advanced Network, or sixth generation (6G) Network.

[0031] As shown in Figure 1, the network device 120 can communicate with the terminal device 110 via at least one of the TRP / panels 130-1, 130-2, 130-3, and 130-4. In the following text, TRP / panel 130-1 may also be referred to as the first TRP / panel, TRP / panel 130-2 as the second TRP / panel, TRP / panel 130-3 as the third TRP / panel, and TRP / panel 130-4 as the fourth TRP / panel. Each of the TRP / panels 130 can provide multiple beams for communication with the terminal device 110. Note that the number of TRP / panels shown in Figure 1 is merely an example and not limited to.

[0032] In some embodiments, the first TRP / panel and / or the second TRP / panel and / or the third TRP / panel and / or the fourth TRP / panel may be explicitly associated with different upper-layer configuration identities. For example, the upper-layer configured identity may be associated with a Control Resource Set (CORESET), reference signal (RS), reference signal resource, group of ports for reference signal resource, or Transmission Configuration Indication (TCI) state, which is used to distinguish transmissions between different TRP / panels 130 and terminal devices 110.

[0033] In some embodiments, before transmitting data to the terminal device 110 (via TRP / panels 130-1 and / or 130-2 and / or 130-3 and / or 130-4, etc.), the network device 120 may transmit control information associated with the data transmission. For example, the control information may schedule a set of resources for data transmission and indicate various transmission parameters related to data transmission, such as a Time Domain Resource Assignment (TDRA), which may include one or more TCI states, Frequency Domain Resource Assignment (FDRA), slot offset and start / length indicator values, Demodulation Reference Signal (DMRS) groups, and Redundancy Version (RV), as defined in the 3GPP® specification.

Terminal device 110 may then attempt to blind decode the DCI in PDCCH within a search space associated with a control resource set (CORESET). As used herein, "CORESET" and / or search space refers to a set of resource element groups (REGs) from which terminal device 110 attempts to blind decode the DCI. A search space indicating the start time and period for monitoring PDCCH in CORESET may be instructed to terminal device 110. In response to successfully decoding the DCI, the terminal device 110 can accordingly perform UL and / or DL ​​data transmission with the network device 120 (for example, data transmission via PDSCH and / or Physical Uplink Shared Channel (PUSCH)).

[0059] Network device 120 may communicate data and control information to terminal device 110 via multiple beams (also referred to as "DL beams"). Terminal device 110 may also communicate data and control information to network device 120 via multiple beams (also referred to as "UL beams"). In the 3GPP specification for new radio (NR), beams are also defined and indicated by parameters of the transmit configuration indicator. For example, there may be a transmission configuration indication (TCI) field in DCI. The value of the TCI field may be referred to as a "TCI code point". A TCI code point can indicate one or more TCI states. Each TCI state includes one or two DL and / or UL reference signals and parameters for establishing a quasi co-location (QCL) relationship between the DMRS port of PDSCH, the DMRS port of PDCCH, the DMRS port of PUSCH, the DMRS port of PUCCH, the SRS port of an SRS resource, or the CSI-RS port of a CSI-RS resource.

[0060] Furthermore, the following description describes several interactions (e.g., exchange of configurations) between the terminal device 110 and the network device 120. It should be understood that these interactions may be implemented using either a single signaling / message / configuration or multiple signaling / message / configurations, including system information, radio resource control (RRC) messages, downlink control information (DCI) messages, uplink control information (UCI) messages, and media access control (MAC) control elements (CE).
