Description

Technical Field

[0001] The present application relates to the field of mobile communication technology, and in particular to a beam selection measurement reporting method and device. Background Art

[0002] When using low-frequency and medium-frequency electromagnetic waves to transmit signals, omnidirectional antennas are used, or signals are sent in the direction of a sector. However, when using high-frequency communication, the attenuation of wireless signals is very large, so beamforming technology is needed to form a directional beam to enhance the power of the transmitted signal in that direction. Therefore, in mobile communication systems, wireless signals are propagated through one beam, or multiple beams work in turn. Using multiple beams can expand the signal coverage range.

[0003] The intermediate device of the present application is based on controlling the propagation of electromagnetic waves in the communication channel by reflection or transmission to improve the performance of the communication system. For example, the intelligent reflecting surface (IRS) is based on the classic concept of reconfigurable reflective array. Specifically, the IRS is a metasurface composed of a large number of tiny elements, which diffusely reflect the incident signal in a controllable manner.

[0004] The introduction of intermediate devices in communication systems increases the requirements for real-time, reconfigurability, and control. For example, the base station can control the parameters of the metasurface or other phase-changing devices to better control the diffusely reflected incident signal to achieve controllable propagation of electromagnetic waves in the communication channel, so as to improve the performance of the communication system in terms of coverage, capacity, and energy efficiency. Since the intermediate device with the metasurface is a newly introduced entity in the communication system, the beam from the base station will change the direction of the beam when it passes through the metasurface. The metasurface can achieve controllable propagation of multiple phase changes. The terminal measures and reports the preferred beam information and measurement-related information, which needs to be optimized in combination with multiple phase controls of the metasurface.

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments of this application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0050] The following details the technical solutions provided by each embodiment of this application in conjunction with the drawings.

[0051] Figure 1 Schematic diagram of an IRS-enhanced multi-antenna wireless communication system.

[0052] The IRS is similar to the dish antenna used in satellite receivers and is a passive device that reflects signals to improve the signal-to-noise ratio. Different phase shift patterns of its different meta-surfaces cause the incident signal to be reflected in different directions as a beam of light. The IRS is a complement to traditional large-scale MIMO technology. Different from large-scale MIMO systems and cooperative relays, although the IRS also attempts to improve the propagation conditions by deploying active hardware components, the IRS only requires very little operating power and is thus suitable for implementation in energy-limited systems. In addition, the IRS can naturally operate in full-duplex mode without the need for expensive self-interference cancellation. Moreover, the IRS is a very thin material that can be deployed on building facades and interior walls. Therefore, once a traditional network is deployed, one or more IRSs can be flexibly deployed to mitigate the detected coverage holes or provide additional capacity in the areas where needed.

[0053] Deploying an intermediate device in a traditional MIMO system is beneficial for two types of beamforming, such as Figure 1 shown, where an IRS is deployed in a system to assist in the communication between a multi-antenna transmitter and a user. The information signal radiates from the transmitter, and there may be a direct path for communication between the transmitter and the user. Meanwhile, the IRS also receives this information signal and will reflect it. With the help of an infrared controller, the main direction of the reflected signal can be controlled. In particular, appropriate phase shifts are introduced on all meta-atoms to deliberately create a coherent combination of their respective scattered signals, thus generating a signal beam focused on the user. The larger the surface, the narrower the beam. This strategy is called energy focusing.

[0054] On the other hand, if there is no direct path due to severe shadowing or blockage, the transmitter should perform beamforming on the IRS. Then, the IRS can act as a non-amplified full-duplex relay to reflect and focus the signal to the terminal device UE to assist in end-to-end communication. In Figure 1 , consider a scenario where a multi-antenna transmitter serves user 1 in the presence of user 2. Assume that the two UEs have different security levels, where the message of user 1 cannot be decoded by user 2. In this case, by adjusting the phase of the scattered signal to stop the signal at user 2, destructive reflection can be performed at the IRS. This strategy is called energy nulling.

[0055] Utilizing these two principles, it is expected that IRSs will have a wide range of applications in various communication systems, including interference management, coverage extension, and capacity improvement, such as wireless communication systems, cognitive radio networks, physical layer security systems, etc.

[0056] It should be noted that the intermediate device of this application controls the waveform parameters of electromagnetic waves during propagation in a communication channel by means of reflection or refraction, etc., to improve the performance of the communication system, and is not limited to using only IRS technology.

[0057] Figure 2 This is a flowchart of an embodiment of the method of this application.

[0058] An embodiment of this application provides a beam selection measurement and reporting method for a wireless communication system. The wireless communication system includes a network device, an intermediate device, and a user equipment. The service signal sent by the network device is reflected by the intermediate device to the user equipment. The method includes the following steps:

[0059] Step 101: Configure the adjustment ability of the intermediate device;

[0060] For the adjustment ability R of the intermediate device, in the r-th (r = 1,..., R) time unit, the beam direction of the downlink signal is adjusted to the r-th direction;

[0061] The adjustment ability is the direction in which the service signal beam can be adjusted. The network device configures R time units. In the r-th (r = 1,..., R) time unit, the direction adjusted by the network device to the intermediate device is the r-th.

[0062] For example, the adjustment ability of the intermediate device for the service signal is the ability to adjust the phase of the wireless signal, that is, different phase adjustment granularities. The intermediate device is controlled by the network device for multi-bit coding to achieve multiple digital states to achieve the adjustment of multiple phase differences. For example, when 2-bit coding is used, four digital states {00, 01, 10, 11} are achieved, and the phase difference between each state is 90 degrees, and the phase adjustment granularity is 4. When 3-bit coding is used, eight digital states {000, 001, 010, 011, 100, 101, 110, 111} are achieved, and the phase difference adjustment of 45 degrees is achieved, and the granularity is 8. The stronger the control ability, the larger the granularity of phase adjustment can be achieved, and the better the information adjustment ability can be achieved.

[0063] Step 102: Configure the beam management reference signal;

[0064] The network device configures the beam management reference signal for the terminal. In the r-th beam direction, M r beam management reference signals are configured.

[0065] Step 103: Measure and report the preferred beam;

[0066] Use the beam management reference signal to compare the quality of M beams. In the uplink signal, the index of the beam management reference signal of L (L≥1) preferred beams is included. Preferably, in the uplink signal, the time unit information r in the R time units and L in the r-th time unit r (1 < L r<M r ) Index of the preferred beam management reference signal.

[0067] Furthermore, in the uplink signal, measurement values of the beam management reference signal are included. Preferably, the measurement value is at least one of reference signal received power (RSRP), reference signal received quality (RSRQ), channel state information (CSI), and block error rate (BLER).

[0068] The uplink signal including the index and measurement value of the beam management reference signal is carried on the uplink physical control channel or the uplink random access channel. The uplink signal is directly sent to the base station or relayed to the base station through an intermediate device.

[0069] The uplink signal here originates from the terminal device, and the terminal measures, obtains, and compares beam qualities, and reports the indices of the beam management reference signals of L (L is greater than or equal to 1) preferred beams and the measurement metric values of the corresponding beam management reference signals.

[0070] For example, according to the configuration information of the network device, the terminal reports the indices of the L (L is greater than or equal to 1) optimal beam management reference signals within R time units. The reported information includes the time unit information r in the R time units, and the L r (1 < L r <M r ) indices of the preferred beam management reference signals, and the measurement metric values of the corresponding beam management reference signals.

[0071] For another example, according to the configuration information of the network device, the terminal reports the index of the optimal beam management reference signal and the corresponding measurement metric value within the rth (r = 1,..., R) time unit. The reported information includes the index L of the preferred beam management reference signal within the rth time unit r (1 < L r <M r ) and the corresponding measurement metric value.

[0072] Figure 3 Flowchart of the embodiment of the method of this application for the network device.

[0073] The method of the first aspect of this application for the network device includes the following steps:

[0074] Step 201: Send adjustment capability information to configure R time units for the intermediate device. In the rth (r = 1,..., R) time unit, the beam direction of the downlink signal is adjusted to the rth direction;

[0075] For example, the network device sends M rA first-level beam, and each first-level beam occupies a set of resources (Resource 1, …, Resource M r ), after being adjusted by an intermediate unit, each time unit respectively forms a second-level beam direction, and each second-level beam direction continues to use the resources of M r first-level beams (Resource 1, …, Resource M r ). Therefore, the signal in any beam direction in the first-level beam, after being adjusted by the intermediate unit, is transmitted through at least one of the R second-level beams.

[0076] Step 202: Transmit configuration information for configuring M r beam management reference signals for the terminal device at the r-th time unit;

[0077] Preferably, at each time unit, N sets of reference signals (N>1) are transmitted, where each set of reference signals contains M r beam management reference signals.

[0078] Step 203: Receive an uplink signal to obtain the indexes of the beam management reference signals of L (L≥1) preferred beams.

[0079] Further, it further includes: receiving an uplink signal to obtain the measured values of the beam management reference signals of L (L≥1) preferred beams.

[0080] Figure 4 This is a flowchart of an embodiment of the method of this application for an intermediate device.

[0081] The method of the first aspect of this application for an intermediate device includes the following steps:

[0082] Step 301: Receive downlink signal adjustment capability information R;

[0083] Step 302: Process the downlink signal according to R time units. At the r-th (r = 1, …, R) time unit, the beam direction of the downlink signal is adjusted to the r-th direction, as shown in Figure 5 .

[0084] Further, at each time unit, N sets of reference signals (N>1) are transmitted, as shown in Figure 6 .

[0085] Further, the phase adjustment capability of the intermediate device has P panels, and the p-th panel can independently control the phase adjustment direction to be R p , so the number of beam directions of the intermediate device is , as shown in Figures 7 - 8 .

[0086] Step 303: Forward the uplink signal from the terminal device, which includes the indexes of beam management reference signals of L (L≥1) preferred beams; further, it also includes the measurement values of the beam management reference signals.

[0087] It should be noted here that step 303 is not necessary. The uplink signal including the indexes and measurement values of the beam management reference signals is carried on the uplink physical control channel or the uplink random access channel. The uplink signal is directly sent from the terminal device to the network device or forwarded to the network device through an intermediate device.

[0088] Figure 5 It is a schematic diagram of R phase adjustment directions.

[0089] For example, considering the introduction of an intermediate device, the intermediate device has the function of phase adjustment for signals. For example, the number of phase adjustment directions of the intermediate device is R. Therefore, the reference signal needs to be sent on R time slots. The r-th time slot contains M r reference signals. Each time slot corresponds to the unique phase adjustment ability of the intermediate device. The r-th time slot corresponds to the phase adjustment ability r of the intermediate device. The terminal uses a fixed receiving beam. The UE obtains and compares beam qualities, and obtains the preferred beam for transmission based on this receiving beam. When all reference signals are measured, the UE can select the best transmission beam based on all measurement information to complete the beam measurement process. As shown in the figure, R = 4, M r = 4. For example, in the reference signal time slot r = 1, the corresponding M r = 4 groups of resources. Each group of resources is used for a downlink beam ( Figure 5 above each group of resources in it, a set of arrows represents 4 first-level beams. The solid arrow is the working beam on this group of resources, Figures 6 - 8 the meaning of the arrows in Figure 5 is the same as that in

[0090] Figure 6 It is a schematic diagram of N reference signal sets.

[0091] For example, considering the introduction of an intermediate device, the intermediate device has the function of phase adjustment for signals. For example, the number of phase adjustment directions of the intermediate device is R. Therefore, the reference signal needs to be sent on R time slots for N reference signal sets. One reference signal set in each time slot contains M r reference signals. Each time slot corresponds to the unique phase adjustment ability of the intermediate device. The terminal uses a fixed receiving beam in each reference signal set. The UE obtains and compares beam qualities, and obtains the preferred beam for transmission based on this receiving beam. When all After the reference signal measurements of all sets are completed, the UE can select the best transceiver beam pair based on all the measurement information to complete the beam measurement process. As shown in the figure, R = 4, M r = 4, N = 2.

[0092] Figure 7 is a schematic diagram of P panels.

[0093] For example, considering the introduction of an intermediate device that has the function of phase adjustment for signals. For example, considering the phase adjustment ability of the intermediate device with P panels, the p-th panel can independently control the phase adjustment direction to be R p , so the phase adjustment direction of the intermediate device is ones. Therefore, the reference signals need to be sent on time slots, each time slot contains M r reference signals, and each time slot corresponds to the unique phase adjustment ability of the intermediate device. The terminal uses a fixed receiving beam, and the terminal device UE acquires and compares beam qualities to obtain the preferred beam transmission based on this receiving beam. As shown in the figure, M r = 4, P = 2, R1 = 2, R2 = 2.

[0094] Figure 8 is a schematic diagram of R phase adjustment directions, N reference signal sets, and P panels.

[0095] For example, considering the introduction of an intermediate device that has the function of phase adjustment for signals. For example, considering the phase adjustment ability of the intermediate device with P panels, the p-th panel can independently control the phase adjustment direction to be R p , so the phase adjustment direction of the intermediate device is ones. Therefore, the reference signals need to be sent on time slots, each time slot contains N reference signal sets, and each reference signal set has M reference signals. Each time slot corresponds to the unique phase adjustment ability of the intermediate device. The terminal uses a fixed receiving beam in each reference signal set, and the UE acquires and compares beam qualities to obtain the preferred beam transmission based on this receiving beam. When the reference signal measurements of all sets are completed, the UE can select the best transceiver beam pair based on all the measurement information to complete the beam measurement process. As shown in the figure, M r = 4, P = 2, R1 = 2, R2 = 2, N = 2.

[0096] Figure 9 is the flowchart of the embodiment of the method of this application for a terminal device.

[0097] Step 401: Receive configuration information, which is used to configure M beam management reference signals for the terminal device in the r-th time unit. r beam management reference signals.

[0098] Step 402: Measure and compare the quality of beams in the r-th time unit.

[0099] Step 403: Transmit an uplink signal, including the indices of the beam management reference signals of L (L≥1) preferred beams; further, it also includes the measured values of the beam management reference signals.

[0100] The terminal measures and reports the indices of the beam management reference signals of L (L greater than or equal to 1) preferred beams and the corresponding numerical values of the reference signal measurement metrics according to the configuration information.

[0101] For example, according to the configuration information, the terminal reports the indices of the L>1 optimal beam management reference signals within R time units. The reported information includes one or more time units r among the R time units, and the L r (1 < L r < M r ) indices of the preferred beam management reference signals, as well as the measured RSRP, RSRQ, CSI, and BLER of the corresponding beam management reference signals.

[0102] For example, according to the configuration information, the terminal measures the beams corresponding to all reference signals and reports the resource index of L = 1 preferred beam. Therefore, the content to be reported includes the time slot corresponding to the reference signal, the resource index of the L = 1 preferred beam in the time slot, and the measured RSRP, RSRQ, CSI, and BLER.

[0103] For example, according to the configuration information, the terminal measures the beams corresponding to all reference signals and reports the resource indices of L>1 preferred beams. Therefore, it is necessary to report the indices of the optimal beam management reference signals within the r-th (r = 1,..., R) time unit. The reported information includes the indices of the preferred beam management reference signals L within the r-th time unit r (1 < L r < M r ) and the measured RSRP, RSRQ, CSI, and BLER of the corresponding beam management reference signals.

[0104] For example, the terminal measures the beams corresponding to all reference signals according to the configuration information and reports the resource indexes of more than L (L>1) preferred beams. Therefore, it is necessary to report the beam management reference signal indexes that are optimal within each r-th (r = 1,..., R) time unit. The terminal reports the resource indexes of L = R preferred beams, corresponding to the preferred beam indexes adjusted by the communication node each time, that is, reports the resource indexes of the preferred beams corresponding to each time slot, as well as the measured RSRP, RSRQ, CSI, and BLER.
