Description

Technical Field

[0002] As 5G communication networks enter the commercialization stage, the next generation (6G) communication technology has been under research to achieve faster and more reliable data transmission. Among these technologies, smart reflective surfaces (IRSs) have attracted the interest of academia and industry.

[0003] Smart reflector is a new type of intelligent passive surface that uses meta-materials to control the phase of the surface in real time, thereby controlling the reflection angle of the incident wave and forming reflected beams in different directions.

[0004] Figure 1 This is a schematic diagram of the intelligent reflecting surface transmission model. As shown in the figure, the terminal can directly receive the signal from the IRS (Intelligent Reflecting Surface), and the link of the signal is different from that received directly from the base station (there is an additional channel (f r )). When the terminal receives, if the signal reflected by the IRS cannot be identified, the number of blind detections of the user will increase.

[0147] In view of the new scenario brought by IRS, in order to reduce the number of user blind detections, the embodiment of the present invention will propose a solution for RNTI applicable to IRS channel or beam scrambling. The specific implementation of the present invention is described below in conjunction with the accompanying drawings.

[0148] In the description process, the implementation on the UE and base station sides will be described respectively, and then an example of the coordinated implementation of the two will be given to better understand the implementation of the solution given in the embodiment of the present invention. This description does not mean that the two must be implemented in coordination or must be implemented separately. In fact, when the UE and the base station are implemented separately, they also solve the problems on the UE side and the base station side respectively, and when the two are used in combination, better technical effects will be obtained.

[0149] Figure 2 A schematic diagram of a flow chart for implementing a channel identification method on a terminal side is shown in the figure, which may include:

[0150] Step 201: The terminal receives an RNTI, where the RNTI is used for the terminal to identify an IRS channel;

[0151] Step 202: The terminal identifies the IRS channel according to the RNTI.

[0152] Figure 3 A schematic diagram of a flow chart of a channel identification method at a base station side is shown in the figure, which may include:

[0153] Step 301: The base station determines an RNTI for scrambling an IRS channel, where the RNTI is used for the terminal to identify the IRS channel.

[0154] Step 302: The base station sends the RNTI to the terminal.

[0155] Specifically, the solution is to define an RNTI dedicated to scrambling the physical channel on the IRS so that the terminal can process the IRS channel. The physical channels on the IRS include one of the following channels or a combination thereof: PBCH (Physical broadcast channel), PRACH (Physical Random Access Channel), PDCCH (Physical downlink control channel), PDSCH (Physical downlink shared channel), PUSCH (Physical Uplink Shared Channel), PUCCH (Physical Uplink Control Channel) channels, etc.

[0156] The implementation of the solution for identifying the RNTI of the IRS link is described below.

[0157] To facilitate understanding, distinction and explanation, several characteristics are first explained.

[0158] The RNTI of the IRS link is called: IRS-RNTI, that is, IRS-RNTI is a general term for the RNTI that scrambles channels such as PBCH, PRACH, PDCCH, PDSCH, PUSCH, PUCCH on the IRS link.

[0159] Base station direct link / channel: The link / channel through which the terminal directly exchanges information with the base station, which is distinguished from the link / channel relayed by the IRS, such as Figure 1 h in d Channel.

[0160] IRS link / channel: The link / channel through which the terminal exchanges information with the base station via the IRS relay, such as Figure 1 f r That is, an IRS link is a link that passes through an IRS relay; and / or an IRS channel is a channel that passes through an IRS relay.

[0161] In implementation, the IRS channel includes one or a combination of the following channels on the IRS link:

[0162] PBCH, PRACH, PDCCH, PDSCH, PUSCH, PUCCH.

[0163] In implementation, after the terminal identifies the IRS channel according to the RNTI, one or a combination of the following processes may be further included:

[0164] In the IRS channel, a channel equalization algorithm or compensation algorithm different from that in the channel where the terminal directly interacts with the base station is used;

[0165] The IRS channel uses a beamforming mode and beamforming coefficient that are different from those of the channel in which the terminal directly interacts with the base station.

[0166] Correspondingly, on the base station side, further comprising the base station performing one or a combination of the following processing on the IRS channel identified according to the RNTI:

[0167] In the IRS channel, a channel equalization algorithm or compensation algorithm different from that in the channel where the terminal directly interacts with the base station is used;

[0168] The IRS channel uses a beamforming mode and beamforming coefficient that are different from those of the channel in which the terminal directly interacts with the base station.

[0169] Specifically, by distinguishing channels through IRS-RNTI, the terminal or base station can adopt a channel equalization or compensation algorithm different from that of the base station's direct line of sight channel for the IRS link; the terminal or base station can also adopt a beamforming method and beamforming coefficient different from that of the base station's direct line of sight channel for the IRS link.

[0170] In implementation, the RNTI includes:

[0171] A common RNTI for sending common information to one or more terminals on an IRS link; and / or,

[0172] A dedicated RNTI used to send dedicated information to the terminal on the IRS link.

[0173] That is, the IRS-RNTI may be divided into a common IRS-RNTI and a dedicated IRS-RNTI.

[0174] The public IRS-RNTI is used for public information sent on the IRS link, and the recipient is one or more terminals, such as broadcast information. The broadcast channel used at this time is scrambled with the public IRS-RNTI. The information transmitted by this broadcast channel may be different from the information sent by the broadcast channel on the macro station. For example, messages such as information during the access process (Msg0 / 1 / 2 / 3) can be sent on the macro station or on the IRS link. IRS-RNTI is used to scramble different channels that carry Msg0 / 1 / 2 / 3 / 4 messages.

[0175] The dedicated IRS-RNTI is used to scramble the channel on the IRS link for sending and receiving data or control information of the terminal. The physical channel can be PDCCH, PDSCH, PUSCH, PUCCH.

[0176] For the configuration of the public IRS-RNTI: it can be a fixed value, directly given in the protocol, or configured in the direct line of sight channel of the base station. That is, the public RNTI is pre-agreed, or is configured by the base station through the channel through which the terminal directly exchanges information with the base station.

[0177] For configuration of dedicated IRS-RNTI: the user is configured through dedicated control signaling or information. That is, the dedicated RNTI is configured by the base station through dedicated control signaling or information.

[0178] The configuration can be carried out through RRC (Radio Resource Control) signaling or PDCCH or MAC CE (Media Access Control Element; MAC: Media Access Control; CE: Control Element).

[0179] In implementation, when the RNTI is configured via PDCCH:

[0180] When the base station needs to exchange information with the terminal through the IRS channel, the RNTI is configured through the link or channel through which the terminal directly exchanges information with the base station, and the RNTI is configured through the IRS link or channel;

[0181] One or a combination of the following parameters of the RNTI is configured in real time through the DCI carried in the PDCCH channel: type, value, valid time window, time period;

[0182] Configuring one or more types of the RNTI at a time;

[0183] Specifically, when the base station requires the terminal to perform information exchange through the IRS, the base station may perform configuration through the base station link / channel, or may perform configuration through the IRS link / channel.

[0184] The type and value of the IRS-RNTI used by the terminal, as well as the valid time window or time period, etc. can be configured in real time through the DCI (Downlink Control Information) carried in the PDCCH channel. One or more types of IRS-RNTI can be configured at one time.

[0185] In implementation, when the RNTI is configured through RRC signaling:

[0186] Configuring the RNTI during terminal link establishment or reconfiguration;

[0187] One or a combination of the following parameters of the RNTI used by the configuration terminal: type, value;

[0188] Specifically, it can be configured to the terminal through RRC signaling, and configured during the terminal link establishment, reconfiguration, etc. Configure the type and value of IRS-RNTI used by the terminal. One or more types of IRS-RNTI can be configured at a time.

[0189] In implementation, when the RNTI is configured through MAC CE:

[0190] Define RNTI, and configure one or more types of the following parameters of the RNTI at one time through MAC CE or a combination thereof: type, value, and valid time period.

[0191] Specifically, the type and value of one or more types of IRS-RNTIs and the valid time period may be configured at one time by defining the IRS-RNTI MAC CE.

[0192] The following describes the implementation of the IRS-RNTI value selection scheme.

[0193] In implementation, the value of the RNTI is identified as [XX, YY], where XX and YY are the maximum and minimum values ​​available for the RNTI, and the maximum and minimum values ​​available are different depending on the type.

[0194] In a specific implementation, the RNTI value range is: 0x0001-0xFFF2.

[0195] Specifically, the value of IRS-RNTI is marked as [XX, YY]: XX and YY represent the maximum and minimum values ​​of IRS-RNTI, and the values ​​vary according to different types.

[0196] According to the existing solution, the RNTI corresponding to the IRS-RNTI may be defined among the available values.

[0197] For example, the definition of IRS-RNTI can be placed in the text of MAC, which can be as follows:

[0198] The bold italic font is IRS-RNTI.

[0199] The common RNTI is in bold.

[0200] The ones in italics are fixed public RNTIs.

[0201] The IRS-RNTI is defined in the available values ​​in the existing scheme. The available value range in the existing scheme is: 0xFFF3-0xFFFD, and several values ​​are taken from it. The SRI-RNTI can also be defined in the already allocated 0x0001-0xFFF2.

[0202] Therefore, SRI-RNTI is added in 0x0001-0xFFF2 as a dedicated RNTI for SRI (SRS resource indicator, SRS resource indicator; SRS: Sounding Reference Signal, Sounding Reference Signal). SRI-SI-RNTI and SRI-P-RNTI are added in 0xFFF3-0xFFFD.
