Description

Method and device for selecting receiving beam

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for selecting a receive beam.

Background

The high-frequency millimeter wave path loss is large, and both the network equipment and the terminal equipment use the array technology to form high-gain directional beams to improve the link gain and support flexible beam alignment. In the access and transmission processes, the network device and the terminal device need to coordinate beam alignment to achieve access synchronization and link quality maintenance. A terminal device with millimeter wave transceiving capability typically supports multiple antenna panels for transceiving, each antenna panel consisting of a small-scale antenna array. Therefore, in a new radio, NR (3 GPP) protocol, the terminal device may switch a synchronization broadcast signal block (SS) block, SSB) sent by the beam receiving network device to perform synchronization and PBCH detection, determine that a beam is randomly accessed, and report the beam of the best network device for receiving SSB detection to perform subsequent signal transceiving and process processing.

The beam management process based on the NR protocol mainly comprises three parts of beam scanning and measurement, beam determination and beam reporting. In the beam scanning and measuring process, the network device sends an SSB, the terminal device periodically switches a beam sent by the beam receiving network device to perform synchronization, and measures a Reference Signal Receiving Power (RSRP) of a beam pair (i.e., one transmitting beam of the network device and one receiving beam of the terminal device form a pair of beams) by using a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS). The beam determination is that the terminal device selects a beam pair for subsequent transceiving according to the measurement result obtained by scanning the beam, for example, selects a beam with the maximum received RSRP. And (3) beam reporting, namely, the terminal equipment selects a beam pair according to the indication of the network equipment and reports the beam pair to the network equipment, wherein the number of reported beams is related to the indication of the network equipment and the capability of the terminal equipment.

Since the high-frequency millimeter waves are shielded, a large loss is caused, and particularly, an antenna panel of the terminal device is easily shielded by a hand. Therefore, in order to minimize the probability of the occurrence of the shielding caused by the holding posture, the terminal device may use a plurality of antenna panels distributed at different positions of the terminal device to achieve 360 ° coverage at maximum. Depending on the size and configuration of the terminal equipment, the antenna panel at different locations can support different terminal equipment array sizes. When terminal equipment scans wave beams to receive SSB, all the arrays on the antenna panel are used for forming narrow wave beams, although high gain can be obtained, the access time is long, the access time is linearly increased along with the number of the wave beams, the long access time influences the effectiveness of the wave beams, and the gain of the narrow wave beams cannot be guaranteed in practice. Especially, when a plurality of antenna panels are provided, the number of beams is obviously increased, the access time delay is very long, and the mobile access of the terminal equipment is influenced. Therefore, when the number of antenna panels of the terminal device is large, the terminal device usually selects one array on each antenna panel to form a wide beam to receive the SSB, selects the antenna panel of the terminal device by using the SSB measurement RSRP, and then trains a narrow beam of the terminal device through subsequent beam management.

At present, when a network device sends an SSB, a terminal device having multiple antenna panels typically forms a wide beam at each antenna panel to receive the beam, and then determines the antenna panel with the largest RSRP for subsequent transmission by detecting the PSS and the SSS in the SSB. Then, in the transmission process, high-quality data transmission is carried out through a narrow beam formed under the antenna panel selected by the terminal equipment. However, in practice, because the array specifications of each antenna panel are different, when the wide beam receiving SSB is formed by using a single array to measure RSRP, the real receiving gain of each antenna panel cannot be reflected, which may cause that an optimal antenna panel cannot be selected, resulting in that the receiving and transmitting throughput of the terminal device is reduced, and the transmission performance of the terminal device is affected.

In order to more clearly describe the technical solution of the embodiment of the present application, the following describes in detail a method and an apparatus for selecting a receive beam provided by the embodiment of the present application with reference to the accompanying drawings.

Fig. 1 illustrates an architecture of a possible communication system to which the method for selecting a receive beam provided in the embodiment of the present application is applied, where the architecture of the communication system includes a network device and at least one terminal device, where: the network device may form a beam to establish a communication link with the at least one terminal device (e.g., terminal device 1 and terminal device 2 shown in the figure).

In this embodiment, the network device and the at least one terminal device may communicate with each other through a beam.

It should be noted that the architecture of the communication system shown in fig. 1 is not limited to include only the devices shown in the figure, and may also include other devices that are not shown in the figure, and specific descriptions of the present application are not listed here.

The communication system shown in fig. 1 may be a multi-carrier communication system, and may also be various Radio Access Technology (RAT) systems, such as Code Division Multiple Access (CDMA), time Division Multiple Access (TDMA), frequency Division Multiple Access (FDMA), orthogonal Frequency Division Multiple Access (OFDMA), single carrier frequency division multiple access (SC-FDMA), and other systems. The term "system" may be used interchangeably with "network". The communication system shown in fig. 1 may also be adapted for future oriented communication technologies. The system architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

The method for selecting a receiving beam provided by the embodiment of the application is suitable for the communication system shown in fig. 1. The steps included in the method provided in the embodiment of the present application are several key steps in the beam management process, and as shown in fig. 2, the specific process of the method includes:

step 201, a terminal device sends first information to a network device, wherein the first information comprises first indication information and second indication information; the first indication information is used for indicating an antenna panel corresponding to each receiving beam of the terminal equipment; the second indication information is used for indicating whether the network equipment compensates the RSRP of the terminal equipment.

Specifically, the terminal device may send the first information to the network device in a beam reporting process in a beam management procedure. In an embodiment, the first information may further include information such as a Channel state information reference signal resource indicator (CSI-RS) resource indicator (CRI) -RSRP/ssb-indicator (Index) -RSRP.

In a possible implementation manner, when the terminal device transmits the first information to the network device, the prime number terminal device may transmit the first information to the network device through a Radio Resource Control (RRC) message, a media access control element (MAC-CE), or Uplink Control Information (UCI).

Wherein, the corresponding relation between the receiving beam and the antenna panel of the terminal device is as follows: one receive beam for each antenna panel or multiple receive beams for each antenna panel. For example, as shown in the reception beam diagram of the terminal device shown in fig. 3, reception beam1 corresponds to antenna panel 0, and reception beams 2 and 3 correspond to antenna panel 1. Of course, only two antenna panels of the terminal device are schematically shown in fig. 3, and it is understood that the terminal device may further include other antenna panels and beams corresponding to the other panels, which are not shown in fig. 3.

In one example, the antenna panel for each receive beam may be a portion of a beam for the terminal device.

In an example, the first indication information may be an antenna panel indication (antenna index), and the antenna panel index may be used to indicate an antenna panel index of the terminal device corresponding to the current CRI, that is, to indicate an antenna panel corresponding to each reception beam of the terminal device.

In a specific implementation, the second indication information may be represented by one indication bit, for example, 1 represents yes, 0 represents no, or 1 represents no, and 0 represents yes, which is not limited in the present application. Of course, there may be other representations than those described above to achieve the same result, and this is not listed here.

Optionally, when reporting the over-term of a group of beams, one second indication information may be shared, so that only one indication bit is needed, and the reporting overhead may be reduced.

For example, the second indication information may specifically include the following two examples:

example a1: the second indication information is whether to perform terminal device antenna panel selection indication, and may be represented by panel selection on.

Example a2: the second indication information is an indication of whether to perform antenna panel gain compensation, and may be represented by a gain indicator.

The second indication information in the above two examples may be implemented to indicate whether the network device compensates RSRP of the terminal device. Optionally, the example a1 is generally applied to a scenario where RSRPs corresponding to all beams reported by the terminal device are selected from beams when the beams are formed by single arrays of different antenna panels; the above example a2 is generally applied to a mixed reporting scenario in which the terminal device supports single-element or multi-element formation of reception beam reception of an antenna panel.

In an optional implementation manner, when reporting beam scanning using a single-array to receive an SSB, the terminal device determines that RSRP of the terminal device needs to be compensated, where the second indication information sent by the terminal device indicates that the network device compensates RSRP of the terminal device, that is, the second indication information indicates that the RSRP of the terminal device is the same; for example, this case is consistent with example a1 above, when panelselectionton on is configured as panelselectionton on =1; in addition to the above situation, the terminal device determines that it is not necessary to compensate RSRP of the terminal device, at this time, the second indication information sent by the terminal device indicates that the network device does not compensate RSRP of the terminal device, that is, the second indication information indicates that the terminal device is not compensated, for example, at this time, the panelselectionOn is configured to be panelselectionOn =0.

In another optional implementation manner, the terminal device may further determine whether to compensate RSRP of the terminal device according to whether to use single-element reception, where this case is consistent with the above example a2, and at this time, if the terminal device uses single-element reception, the gaincompressor is configured to be 1, that is, the second indication information indicates a yes condition, otherwise, the gaincompressor is configured to be 0, and the second indication information indicates a no condition.

It should be noted that, in the embodiment of the present application, only the case of compensating the RSRP is described, and it is understood that the present application is not limited to the RSRP, but may also be other parameters, for example, reference Signal Received Quality (RSRQ), reference signal received strength indicator (RSSI), signal quality indicator (CQI), signal to interference and noise Ratio (SINR), and the like. The same technical effect as the RSRP compensation can be achieved by compensating the enumerated parameters, and the parameters can be replaced with each other. In the following examples, only RSRP is described in detail.

It should be noted that, in the embodiment of the present application, only the first indication information and the second indication information are described to be sent together through the first information, but the sending mode of the first indication information and the second indication information is not limited to the mode mentioned in the embodiment of the present application. For example, the first indication information and the second indication information may be separately sent through two pieces of information, or there may be other sending manners, which is not specifically limited in this application.

Step 202, the network device determines a receiving beam used by the terminal device for transmission according to the first indication information and the second indication information.

Specifically, step 202 is a beam determination process in the beam management procedure. Specifically, the network device executes different operations according to the difference indicated by the second indication information, and specifically, the following three cases may be referred to.

Case b1: when the second indication information indicates that the network device does not compensate RSRP of the terminal device, and the network device executes step 202, the specific method may be:

and the network equipment determines the RSRP value of the receiving beam corresponding to each antenna panel according to the first indication information, determines the receiving beam with the maximum RSRP value, and then takes the determined receiving beam as the receiving beam for transmission.

In the above method, the second indication information may be the case of the example a1 or the example a2, and the method may be adopted as long as the second indication information indicates that the network device does not compensate RSRP of the terminal device. At this time, the second indication information may be represented by an indication bit 0, and when the network device recognizes that a value corresponding to the second indication information is 0, the receiving beam is determined by using the above method.

For example, the terminal device reports two receiving beams beam0 and beam1, RSRP values corresponding to the two receiving beams are RSRP 0 and RSRP 1, respectively, the first indication information indicates that the beam0 corresponds to the antenna panel 0 and the beam1 corresponds to the antenna panel 1, and the network device does not compensate the RSRP of the terminal device based on the RSRP indicated by the second indication information, and then directly selects a receiving beam with a larger value between RSRP 0 and RSRP 1 as the receiving beam for transmission according to the RSRP value of the receiving beam corresponding to each antenna panel, that is, selects a receiving beam with a larger value between RSRP 0 and RSRP 1 as the receiving beam for transmission, and then the subsequent terminal device selects an antenna panel for transmission.

Case b2: when the second indication information indicates whether to perform terminal device antenna panel selection indication (that is, the second indication information is the case in example a 1), and when the second indication information indicates that the network device compensates RSRP of the terminal device, the network device may perform step 202, specifically:

the network equipment determines the relative receiving gain of each antenna panel and the initial RSRP value of the receiving beam corresponding to each antenna panel according to the first indication information;

the network device determines a compensated RSRP value for each receive beam according to the relative receive gain of each antenna panel and the initial RSRP value for each receive beam;

and the network equipment determines the receiving beam with the maximum compensated RSRP value as the receiving beam for transmission.

A method for the network device to determine the initial RSRP value of the receive beam corresponding to each antenna panel according to the first indication information is similar to the method for the network device to determine the RSRP value of the receive beam corresponding to each antenna panel according to the first indication information in case 1, and may refer to each other.

Specifically, the network device determines the relative receiving gain corresponding to each antenna panel according to the first indication information, which may be that the network device searches for a corresponding relationship between the antenna panel and the relative receiving gain according to the first indication information, and further determines the relative receiving gain corresponding to each antenna panel. Optionally, the correspondence between the antenna panel and the relative reception gain may be stored in the network device in a table form, and may of course be stored in the network device in a form other than a table form.

In an embodiment, the relative reception gain of each antenna panel is sent to the network device by the terminal device in a terminal device capability reporting process before the terminal device sends the first information to the network device. Specifically, the terminal device may send third information to the network device, where the third information includes a relative reception gain of each antenna panel. Optionally, the relative reception gain is referred to a reception gain of an antenna panel with the worst reception gain, and the relative reception gain of each antenna panel is a positive value. For example, the relative receive gain of each antenna panel may be represented by a relative receive gain parameter (rGainPanel), illustratively, the relative receive gain of antenna panel n is rGainPanel [ n ]]N =0,1,2 … …, N-1, where N is the number of antenna panels. For example, rGainPanel [ n ]]＝i _n Denotes the relative receiving gain of i corresponding to the antenna panel n _n ，i _n The value of (d) can be {1,2,3,4,5,6,7 … … }.

In an optional implementation manner, the method for determining the relative receive gain by the terminal device may be that, assuming that the terminal device has N antenna panels, a single-array sub-gain of an antenna panel N (N =0,1,2 _e (N) (the value is a real number greater than 0) and the number of the included arrays is N _ant (n) (taking an integer greater than 0), the relative gain of the panel n may be:

rGainPanel[n]＝G _e (n)+10log ₁₀ (N _ant (n))-G _max ，

wherein, G _max ＝max _{n＝1,2,……，N} G _e (n)+10log ₁₀ (N _ant (n))。

Specifically, it is assumed that the terminal device reports M receiving beams, and an initial RSRP value of the M receiving beams is RSRP _m The index of the antenna panel corresponding to the receiving beam indicated by the first information is i _m M =0,1, … … M-1. When panelselectionton (i.e. the second indication information) is 1, the network device first indexes i according to the antenna panels _m Determining a relative receive gain Δ G of an antenna panel corresponding to a receive beam m _im ＝rGainPanel[i _m ]Then based on the compensated RSRP value RSRP _m +ΔG _im And selecting the receiving beam with the maximum compensated RSRP value.

For example, the terminal device reports two receiving beams beam0 and beam1, the initial RSRP values corresponding to the two receiving beams are RSRP 0 and RSRP 1, respectively, and the first indication information indicates that the beam0 corresponds to the antenna panel 0 and the beam1 corresponds to the antenna panel 1. When panelselectionton (i.e., the second indication information) is 1, the network device finds that the relative receiving gain of the antenna panel 0 is Δ G according to the first indication information ₀ The relative reception gain of the antenna panel 1 is Δ G ₁ Then the network equipment obtains the RSRP value of beam0 after compensation as RSRP ₀ +ΔG ₀ Obtaining the RSRP value after beam1 compensation as RSRP ₁ +ΔG ₁ And then determining the receiving beam with the maximum compensated RSRP value. For example, the selection process may refer to the selection process of the receive beam shown in fig. 4.

Case b3: when the second indication information indicates whether to perform antenna panel gain compensation indication, that is, when the second indication information is the case in the above example a 2), and when the second indication information indicates that the network device compensates RSRP of the terminal device, the network device may perform step 202, specifically:

the network equipment determines the relative receiving gain of each antenna panel, the compensation gain of the receiving beam corresponding to each antenna panel and the initial RSRP value of the receiving beam corresponding to each antenna panel according to the first indication information;

the network device determines a compensated RSRP value for each receive beam according to the relative receive gain for each antenna panel, the compensation gain for each receive beam, and the initial RSRP value for each receive beam;

A method for the network device to determine the initial RSRP value of the receive beam corresponding to each antenna panel according to the first indication information is also similar to the method for the network device to determine the RSRP value of the receive beam corresponding to each antenna panel according to the first indication information in case 1, and reference may be made to each other.

Wherein, the network device determines the relative receiving gain corresponding to each antenna panel according to the first indication information, which is similar to the related content in case 2, and the method processes may be mutually referred to, and are not described herein again.

Specifically, the network device determines the compensation gain of the receiving beam corresponding to each antenna panel according to the first indication information, which may be that the network device searches for a corresponding relationship between the antenna panel and the compensation gain of the corresponding receiving beam according to the first indication information, and further determines the compensation gain of the receiving beam corresponding to each antenna panel. Optionally, the correspondence between the compensation gains of the antenna panels and the corresponding receiving beams may be stored in the network device in a table form, or may be stored in the network device in a form other than a table.

In an embodiment, the compensation gain of the receiving beam corresponding to each antenna panel is sent to the network device by the terminal device in a terminal device capability reporting process before the terminal device sends the first information to the network device. Specifically, the terminal device may lead to transmitting the compensation gain of each antenna panel through the third information. In another embodiment, the terminal device may further transmit the compensation gain of each antenna panel to the network device through another information (e.g., fourth information) different from the third information.

Specifically, it is assumed that the terminal device reports M receiving beams, and an index of an antenna panel corresponding to the receiving beam indicated by the first information is i _m M =0,1, … … M-1, the initial RSRP value of the corresponding receive beam is RSRP _m The compensation gain of the corresponding antenna panel is indicated as j _m . When the gain indicator (i.e. the second indication information) is j _m When =1, the network device is based on the compensated RSRP value RSRP _m +j _m ΔG _im And selecting the receiving beam with the maximum compensated RSRP value. Wherein, Δ G _im The values of (a) can be referred to the related description in the above case b2, and are not repeated herein.

For example, the terminal device reports two receiving beams beam0 and beam1, the initial RSRP values corresponding to the two receiving beams are RSRP 0 and RSRP 1, respectively, and the first indication information indicates that beam0 corresponds to antenna panel 0 and beam1 corresponds to antenna panel 1. When the gain indicator (i.e., the second indication information) is 1, the network device finds that the relative receiving gain of the antenna panel 0 is Δ G according to the first indication information ₀ The relative reception gain of the antenna panel 1 is Δ G ₁ (ii) a And the network equipment searches whether the compensation gain of beam0 corresponding to the antenna panel 0 is gain indicator according to the first indication information ₀ (i.e., j) ₀ ) The compensation gain of beam1 corresponding to the antenna panel 1 is gain indicator ₁ (i.e., j) ₁ ). Then the network equipment obtains the RSRP value of beam0 after compensation as RSRP ₀ +j ₀ ×ΔG ₀ Obtaining the compensated RSRP value of beam1 as RSRP ₁ +j ₁ ×ΔG ₁ Then determining compensated RThe reception beam with the largest SRP value. For example, the selection process may refer to the selection process of the receive beam shown in fig. 5.

In cases b1, b2, and b3, when selecting a reception beam, a reception beam having the largest RSRP value (or compensated RSRP value) is selected. In practice, when selecting a receiving beam, one of the receiving beams with RSRP value (or compensated RSRP value) greater than or equal to a set threshold may be selected, where selecting the receiving beam with the largest RSRP value (or compensated RSRP value) is only one of the most effective ways, but does not limit the present application.

In an optional embodiment, in a case that only one receiving beam needs to be selected, the method in the above cases b1, b2, and b3 may be adopted, but in a case that multiple receiving beams need to be selected, multiple receiving beams with RSRP values (or compensated RSRP values) greater than or equal to a set threshold may be selected, and it is relatively good to select multiple receiving beams with RSRP values (or compensated RSRP values) ranked in size and located in the first few.

The set threshold may be configured according to a pre-link budget.

It should be noted that, the method for selecting a receiving beam by using other parameters is similar to the method for using the parameter RSRP, and may refer to each other, for example, when using SNR or SINR, the RSRP value in the above process may be directly replaced by the SNR value or SINR value, and then the SNR value (or compensated SNR value) or compensated SINR value (or compensated SINR value) may be obtained. The detailed process is not described herein.

Step 203, the network device sends second information to the terminal device, where the second information is used to notify the terminal device of the receiving beam for transmission.

Specifically, the process of sending the second information to the terminal device by the network device is also the process of beam indication in the wave velocity management flow. Specifically, after the network device selects the receiving beam for transmission in the beam indication process, the terminal device is instructed to receive data or signals using a specific receiving beam by using a quasi-co-location (QCL) relationship defined by a protocol.

In a possible implementation manner, when the network device sends the second information to the terminal device, the network device may send the second information to the terminal device through Downlink Control Information (DCI), MAC-CE, or RRC.

In a specific implementation, after the terminal device receives the indication of the network device, the terminal device determines an antenna panel corresponding to the receiving beam used for transmission, and in a subsequent transmission process, the terminal device performs transmission using a receiving beam formed by the antenna panel determined last.

It should be noted that, when the terminal device sends the first information to the network device and the network device sends the second information to the terminal device, the first information and the second information may be sent using the same or different service frequencies, for example, the frequency for sending the first information may be a certain frequency less than 6GHz, the frequency for sending the second information may be 28GHz, or other possible combinations, which are not listed here.

By adopting the method for selecting the receiving beam provided by the embodiment of the application, the terminal equipment sends first information to the network equipment, wherein the first information comprises first indication information and second indication information; the first indication information is used for indicating an antenna panel corresponding to each receiving beam of the terminal equipment; the second indication information is used for indicating whether the network equipment compensates the RSRP of the terminal equipment or not; and after determining the receiving beam used for transmission by the terminal equipment according to the first indication information and the second indication information, the network equipment sends second information to the terminal equipment, wherein the second information is used for informing the terminal equipment of the receiving beam used for transmission. By the method, the terminal equipment can determine the subsequent antenna panel for transmission by combining the receiving beam selected by the network equipment, so that the subsequent terminal equipment can transmit through the selected better antenna panel, the receiving and transmitting throughput of the terminal equipment can be improved, and the transmission performance of the terminal equipment can be improved.

In a specific implementation, in addition to the above steps, the beam management process may further include an SSB transmission process, a random access process, and a terminal device capability reporting process, which are all before the steps included in the method for selecting a receiving beam provided in the embodiment of the present application. Specifically, a beam management process applicable to the method for selecting a receiving beam provided by the embodiment of the present application may be shown in fig. 6, and the specific beam management process may include:

step 601: the network device sends the SSB to the terminal device.

Wherein the method by which the network device sends the SSB may rely on prior art protocols. The SSB Burst defaults to a transmission period of 20ms. The number of SSBs included in the SSB Burst is determined by the network device. And the terminal equipment forms a wide beam by using a single antenna array according to the standard convention and a time window of 5ms to receive the SSB sent by the network equipment and perform synchronization and beam measurement to obtain an optimal beam pair and corresponding RSRP.

Step 602: and the terminal equipment performs random access.

The terminal equipment carries out random access according to a 4-step random access process specified by a protocol: RACH Preamble transmission, MSG2, MSG3 and MSG4. At this time, the terminal device selects and uses the antenna panel determined in the SSB scanning process to transmit the relevant signal in the random access process.

Step 603: and the terminal equipment reports the terminal equipment capacity.

In the process of reporting the capability of the terminal device, the terminal device may report the reported information in the embodiment shown in fig. 2, and in addition to the above-mentioned information, the terminal device may also report the number of antenna panels included in the terminal device. Optionally, the number of the antenna panels may be represented by nrofReportPanel, where a value of nrofReportPanel may be M = {1,2,3,3,4,5,6,7,8 … … }.

In an optional embodiment, the reporting of the capability of the terminal device in step 603 may be implemented through a random access procedure in step 602, that is, the step 602 may include the content reported in step 603, which is not limited in this application.
