Description

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on October 12, 2019, with application number 201910967620.5 and invention name “Electronic device, wireless communication method and computer-readable storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] Embodiments of the present disclosure generally relate to the field of wireless communications, and more particularly, to electronic devices, wireless communication methods, and computer-readable storage media. More specifically, the present disclosure relates to an electronic device serving as a network-side device in a wireless communication system, an electronic device serving as a user equipment in the wireless communication system, a wireless communication method performed by the network-side device in the wireless communication system, a wireless communication method performed by the user equipment in the wireless communication system, and a computer-readable storage medium. Background Art

[0003] Beamforming is a signal preprocessing technology based on antenna arrays. Beamforming generates a directional beam by adjusting the weighting coefficients of each element in the antenna array, thereby achieving significant array gain. Therefore, beamforming technology has significant advantages in expanding coverage, improving edge throughput, and suppressing interference. During beam scanning, the network device can use multiple transmit beams to send downlink signals to the user device, and the user device can use multiple receive beams to receive downlink signals. The channel quality between the transmit and receive beams is measured, such as RSRP (Reference Signal Receiving Power). The network device can use this channel quality information to determine the transmit beam used to send downlink information, and the user device can use this channel quality information to determine the receive beam used to receive downlink information.

[0004] Network-side devices can use measurement resources to carry downlink signals. Different measurement resources can correspond to the same transmit beam or different transmit beams. When a network-side device uses a measurement resource to send a downlink signal to a user equipment (UE) using a specific transmit beam, the UE can use this measurement resource to measure the channel quality between the transmit beam and the receive beam. Therefore, this measurement resource can be called a Channel Measurement Resource (CMR) for the UE. However, the downlink signal carried on this measurement resource may be an interference signal for other UEs. Therefore, this measurement resource can be called an Interference Measurement Resource (IMR) for other UEs.

[0005] Therefore, simply calculating RSRP by a user device cannot reflect the intra-cell interference situation it is experiencing, and thus cannot accurately reflect the channel quality between the transmit and receive beams. Therefore, it is necessary to propose a technical solution that enables the user device to reflect the interference situation when calculating the channel quality between the transmit and receive beams, thereby enabling network-side equipment and the user device to more rationally select transmit and receive beams. Summary of the Invention

[0006] This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.

[0007] The purpose of the present disclosure is to provide an electronic device, a wireless communication method and a computer-readable storage medium, so that the user equipment can reflect the interference situation when calculating the channel quality between the transmit beam and the receive beam, so that the network side equipment and the user equipment can more reasonably select the transmit beam and the receive beam.

[0008] According to one aspect of the present disclosure, an electronic device is provided, including a processing circuit, configured to: configure one or more channel measurement resources (CMRs) and one or more interference measurement resources (IMRs); and send a downlink signal to a user equipment using a transmit beam corresponding to the one or more CMRs, so that the user equipment: receives the downlink signal from the transmit beam using a receive beam, determines a signal power based on a signal quality measured on the CMRs, determines an interference power based on a signal quality measured on the IMRs, and determines a signal-to-interference-and-noise ratio (SIR) between the transmit beam and the receive beam based on the signal power and the interference power.

[0009] According to another aspect of the present disclosure, an electronic device is provided, including a processing circuit, configured to: receive a downlink signal of a transmit beam corresponding to one or more channel measurement resources (CMRs) from a network-side device using a receive beam, wherein the network-side device is configured with one or more CMRs and one or more interference measurement resources (IMRs); determine a signal power based on a signal quality measured on the CMR; determine an interference power based on a signal quality measured on the IMR; and determine a signal-to-interference-and-noise ratio (SIN) between the transmit beam and the receive beam based on the signal power and the interference power.

[0011] According to another aspect of the present disclosure, a wireless communication method performed by an electronic device is provided, including: receiving, using a receive beam, a downlink signal of a transmit beam corresponding to one or more channel measurement resources (CMRs) from a network-side device, wherein the network-side device is configured with one or more CMRs and one or more interference measurement resources (IMRs); determining a signal power based on a signal quality measured on the CMR; determining an interference power based on a signal quality measured on the IMR; and determining a signal-to-interference-and-noise ratio (SIN) between the transmit beam and the receive beam based on the signal power and the interference power.

[0012] According to another aspect of the present disclosure, a computer-readable storage medium is provided, comprising executable computer instructions, which, when executed by a computer, enable the computer to perform the wireless communication method according to the present disclosure.

[0013] Using the electronic device, wireless communication method, and computer-readable storage medium disclosed herein, a network device can configure one or more CMRs and one or more IMRs, and use the transmit beams corresponding to the one or more CMRs to send downlink signals to a user device. The user device can then use a receive beam to receive the downlink signal and determine the signal power based on the signal quality measured on the CMRs and the interference power based on the signal quality measured on the IMRs, thereby determining the signal-to-interference-and-noise ratio (SINR) between the transmit and receive beams. This allows the user device to reflect the interference situation when calculating the channel quality between the transmit and receive beams, enabling the network device and user device to more rationally select transmit and receive beams.

[0032] Examples of the present disclosure will now be described more fully with reference to the accompanying drawings.The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses.

[0033] Example embodiments are provided so that the present disclosure will be exhaustive and will fully convey its scope to those skilled in the art.

In some example embodiments, well-known processes, well-known structures, and well-known technologies are not described in detail.

[0034] The description will be in the following order:

[0036] 2. User equipment configuration example;

[0037] 3. Method embodiments; and

[0038] 4. Application examples.

[0039] <1. Example of Network-Side Device Configuration>

[0040] Figure 1 1 is a block diagram illustrating an example of a configuration of an electronic device 100 according to an embodiment of the present disclosure. The electronic device 100 herein may serve as a network-side device in a wireless communication system, specifically, as a base station device in the wireless communication system.

[0041] like Figure 1 As shown, the electronic device 100 may include a configuration unit 110 , a processing unit 120 and a communication unit 130 .

[0042] Here, each unit of the electronic device 100 may be included in a processing circuit. It should be noted that the electronic device 100 may include either one processing circuit or multiple processing circuits. Furthermore, the processing circuit may include various discrete functional units to perform various functions and / or operations. It should be noted that these functional units may be physical entities or logical entities, and units with different names may be implemented by the same physical entity.

[0043] According to an embodiment of the present disclosure, the configuration unit 110 may configure one or more CMRs and one or more IMRs.

[0044] According to an embodiment of the present disclosure, the processing unit 120 may control the execution of a beam scanning process. For example, during the P2 process, the processing unit 120 may control the electronic device 100 to transmit a downlink signal to the user equipment using each of the multiple transmit beams. For another example, during the P3 process, the processing unit 120 may control the electronic device 100 to transmit a downlink signal to the user equipment using the same transmit beam.

[0045] In the prior art, the P2 process and the P3 process are important stages in the beam scanning process. The network-side device can use the P2 process to select a suitable transmit beam, and the user device can use the P3 process to select a suitable receive beam. Specifically, in the P2 process, the network-side device uses multiple transmit beams to send downlink signals to the user device, and the user device uses the same receive beam to receive the downlink signal. As a result, the user device can measure the channel quality between each transmit beam and the receive beam and feed back the measured channel quality to the network-side device, so that the network-side device can know the transmit beam that the user device expects the network-side device to use and then determine a suitable transmit beam to perform the data transmission process. In the P3 process, the network-side device uses one transmit beam to send a downlink signal to the user device, and the user device uses multiple receive beams to receive the downlink signal. As a result, the user device can measure the channel quality between the transmit beam and each receive beam, so as to determine a suitable receive beam to perform the data transmission process.

[0046] According to an embodiment of the present disclosure, the electronic device 100 can use the transmission beam corresponding to one or more CMRs to send a downlink signal to the user equipment through the communication unit 130, so that the user equipment: receives the downlink signal from the transmission beam using the reception beam, determines the signal power based on the signal quality measured on the CMR, determines the interference power based on the signal quality measured on the IMR, and determines the signal-to-interference-and-noise ratio between the transmission beam and the reception beam based on the signal power and the interference power.

[0047] Thus, according to the electronic device 100 of the embodiment of the present disclosure, one or more CMRs and one or more IMRs can be configured, and downlink signals can be sent to the user equipment using the transmit beams corresponding to the one or more CMRs, so that the user equipment can receive the downlink signal using the receive beam, and determine the signal power based on the signal quality measured on the CMR, and determine the interference power based on the signal quality measured on the IMR, and determine the signal-to-interference-and-noise ratio between the transmit beam and the receive beam. As a result, the user equipment can reflect the interference situation when calculating the channel quality between the transmit beam and the receive beam, so that the network-side device and the user equipment can more reasonably select the transmit beam and the receive beam.

[0048] In the embodiments of the present disclosure, a CMR may be a CSI-RS (Channel State Information-Reference Signal) resource or an SSB (Synchronization Signal Block) resource. An IMR may also be a CSI-RS resource or an SSB resource. Furthermore, a CMR may be an NZP (Non-Zero Power)-CMR, and an IMR may also be an NZP-IMR.

[0049] According to an embodiment of the present disclosure, the configuration unit 110 may configure K CMRs corresponding one-to-one to K transmit beams, and configure one or more corresponding IMRs for each CMR, where K is an integer greater than 1. Furthermore, the electronic device 100 may transmit a downlink signal to a user equipment using each of the K transmit beams through the communication unit 130, so that the user equipment receives the downlink signal from each transmit beam using the same receive beam.

[0050] Figure 2 Schematic diagram showing the P2 process according to the prior art. Figure 2 As shown, during the P2 process, the network device uses each of multiple transmit beams to transmit a downlink signal to the user device, and the user device uses the same receive beam to receive the downlink signal. As a result, the user device can calculate the channel quality between each transmit beam and the receive beam. The network device can then determine the appropriate transmit beam for data transmission based on the channel quality calculated by the user device.

[0051] Figure 3 : is a schematic diagram showing the configuration of CMR and IMR in the P2 process according to an embodiment of the present disclosure. Figure 3As shown, the configuration unit 110 can configure K CMRs corresponding to K transmit beams one by one, and configure Mk IMRs corresponding to the kth CMR, where k is an integer from 1 to K, K is an integer greater than 1, and Mk is a positive integer. Here, M1 to MK can be the same value or different values. That is, the configuration unit 110 can configure the same number of corresponding IMRs for each CMR, or configure a different number of corresponding IMRs for each CMR. Further, the configuration unit 110 can configure the same one or more IMRs for each CMR, or configure one or more different IMRs for each CMR. In addition, the K transmit beams can be all transmit beams of the electronic device 100. Here, the Mk IMRs corresponding to the kth transmit beam refer to the transmit beam that needs to be considered when the electronic device 100 uses the kth transmit beam to send a downlink signal to a specific user equipment and causes interference to the user equipment.

[0052] According to an embodiment of the present disclosure, for any transmit beam, the user equipment can determine the signal power between the transmit beam and the receive beam of the user equipment based on the signal quality measured on the CMR corresponding to the transmit beam, and determine the interference power between the transmit beam and the receive beam of the user equipment based on the signal quality measured on all or part of the IMR corresponding to the CMR, and determine the signal-to-interference-plus-noise ratio between the transmit beam and the receive beam of the user equipment based on the signal power and the interference power.

[0053] For example, for the first transmit beam corresponding to the first CMR, the user equipment can determine the signal power between the first transmit beam and the receive beam of the user equipment based on the signal quality measured on the first CMR, determine the interference power between the first transmit beam and the receive beam of the user equipment based on the signal quality measured on all or part of the M1 IMRs corresponding to the first CMR, and then determine the signal-to-interference-plus-noise ratio between the first transmit beam and the receive beam of the user equipment based on the signal power and the interference power.

[0054] Similarly, for the second transmit beam corresponding to the second CMR, the user equipment can determine the signal power between the second transmit beam and the user equipment's receive beam based on the signal quality measured on the second CMR, determine the interference power between the second transmit beam and the user equipment's receive beam based on the signal quality measured on all or part of the M2 IMRs corresponding to the second CMR, and then determine the signal-to-interference-plus-noise ratio between the second transmit beam and the user equipment's receive beam based on the signal power and the interference power. Thus, in a similar manner, the user equipment can determine the signal-to-interference-plus-noise ratio between each of the K transmit beams and the user equipment's receive beam. As a result, the user equipment can more accurately understand the channel conditions of each beam.

[0055] According to an embodiment of the present disclosure, the configuration unit 110 may configure one or more corresponding IMRs for each CMR through RRC (Radio Resource Control) signaling, so that the user equipment determines the interference power based on the signal quality measured on all IMRs corresponding to the CMR. For example, for the first transmit beam corresponding to the first CMR, the user equipment may determine the interference power between the first transmit beam and the user equipment's receive beam based on the signal quality measured on all IMRs among the M1 IMRs corresponding to the first CMR.

[0056] According to an embodiment of the present disclosure, the configuration unit 110 may further configure one or more corresponding IMRs for each CMR through RRC signaling, and activate one or more IMRs in the IMRs corresponding to each CMR through MAC (Media Access Control) signaling, such as a MAC CE (Control Element) or a DCI (Downlink Control Information), so that the user equipment determines the interference power based on the signal quality measured on the activated IMRs corresponding to the CMR. For example, assuming that among the M1 IMRs corresponding to the first CMR (assuming that M1 is an integer greater than or equal to 3), the activated IMRs are the first IMR and the third IMR, the user equipment may determine the interference power between the first transmit beam and the user equipment's receive beam based on the signal quality measured on the first IMR and the third IMR in the M1 IMRs corresponding to the first CMR.

[0057] According to an embodiment of the present disclosure, the electronic device 100 may receive signal-to-interference-plus-noise ratio information from the user equipment through the communication unit 130. The signal-to-interference-plus-noise ratio information includes a signal-to-interference-plus-noise ratio between one or more transmit beams and a receive beam among the K transmit beams.

[0058] According to the embodiments of the present disclosure, Figure 1 As shown, the electronic device 100 may further include a determining unit 140, configured to determine a signal to interference plus noise ratio between one or more transmit beams of the K transmit beams and the receive beam according to the signal to interference plus noise ratio information.

[0059] According to an embodiment of the present disclosure, the signal to interference plus noise ratio information may further include identification information of the CMR to which each signal to interference plus noise ratio corresponds. Thus, the determination unit 140 may determine the CMR or transmit beam corresponding to each signal to interference plus noise ratio.

[0060] According to an embodiment of the present disclosure, the signal-to-interference-and-noise ratio information may include a single signal-to-interference-and-noise ratio, for example, if the user equipment reports only the maximum value among all signal-to-interference-and-noise ratios. The signal-to-interference-and-noise ratio information may also include multiple signal-to-interference-and-noise ratios, for example, if the user equipment reports both the maximum and minimum values ​​among all signal-to-interference-and-noise ratios.

[0061] According to an embodiment of the present disclosure, because the user equipment determines the interference power based on all or some of the activated IMRs in the IMR corresponding to the CMR, the electronic device 100 is aware in advance of the IMR for which the signal-to-interference-and-noise ratio is intended. Therefore, the signal-to-interference-and-noise ratio information only needs to include the CMR identifier and the corresponding signal-to-interference-and-noise ratio value. Table 1 shows an example of signal-to-interference-and-noise ratio information received by the electronic device 100.

[0062] Table 1

[0063] CMR logo Signal-to-interference-and-noise ratio (SINR) The first signal-to-interference-and-noise ratio CMR1 SINR1 … … … Pth signal-to-interference-and-noise ratio CMR5 SINRP

[0064] Alternatively, according to an embodiment of the present disclosure, the configuration unit 110 may configure one or more corresponding IMRs for each CMR through RRC signaling, and the user equipment may select some IMRs from the IMRs corresponding to the CMRs to determine the interference power. In this case, the electronic device 100 does not know the IMR to which each signal-to-interference-and-noise ratio value corresponds. Therefore, the signal-to-interference-and-noise ratio information may further include identification information of the one or more IMRs to which each signal-to-interference-and-noise ratio corresponds.

[0065] According to embodiments of the present disclosure, because the user equipment can select some IMRs from the IMRs corresponding to the CMRs to determine interference power, the user equipment can determine multiple signal-to-interference-and-noise ratio values ​​for a single CMR or transmit beam based on different IMR combinations. For example, among the M1 IMRs corresponding to the first CMR, the user equipment can select the first and second IMRs to calculate a single signal-to-interference-and-noise ratio value, or select the third IMR to calculate another signal-to-interference-and-noise ratio value. As a result, the signal-to-interference-and-noise ratio information received by the electronic device 100 can include one or more signal-to-interference-and-noise ratios for a single transmit beam.

[0066] Table 2 shows an example of signal-to-interference-and-noise ratio information received by another electronic device 100 .

[0067] Table 2

[0068]

[0069]

[0070] According to an embodiment of the present disclosure, the configuration unit 110 may configure a CMR and all IMRs corresponding to the CMR to have a QCL (Quasi-co-located) Type D relationship. That is, the user equipment receives the CMR and all IMRs corresponding to the CMR using the same receive beam.

[0071] According to an embodiment of the present disclosure, the configuration unit 110 may configure a TCI (Transmission Configuration Indication) state for a CMR to indicate to the user equipment the receive beam for receiving the CMR. In this case, the configuration unit 110 may not configure the TCI state for all IMRs corresponding to the CMR, and the user equipment may use the receive beam for receiving the CMR to receive all IMRs corresponding to the CMR. Conversely, the configuration unit 110 may configure a TCI state for an IMR corresponding to a CMR to indicate to the user equipment the receive beam for receiving the IMR. In this case, the configuration unit 110 may not configure the TCI state for the CMR, and the user equipment may use the receive beam for receiving the IMR corresponding to the CMR to receive the CMR.

[0072] According to the embodiments of the present disclosure, Figure 1 As shown, the electronic device 100 may further include a coordination unit 150, which may determine, based on signal-to-interference-and-noise ratio information from the user equipment, an appropriate transmit beam for transmitting downlink data to the user equipment. For example, the coordination unit 150 may select a transmit beam with a higher signal-to-interference-and-noise ratio to transmit downlink data to the user equipment, and may try to avoid selecting a transmit beam with a lower signal-to-interference-and-noise ratio to transmit downlink data to the user equipment.

[0073] In addition, the coordination unit 150 may also determine a transmit beam for sending downlink data to other user equipment based on the signal-to-interference-plus-noise ratio information from the user equipment. For example, when the signal-to-interference-plus-noise ratio information received by the electronic device 100 indicates that the signal-to-interference-plus-noise ratio of the user equipment is relatively low due to CMR1, IMR2, and IMR3, the electronic device 100 may avoid using IMR2 and IMR3 to send downlink data to other user equipment to reduce interference with the user equipment.

[0074] As described above, during the P2 process, the electronic device 100 can configure K CMRs corresponding one-to-one to the K transmit beams, and configure one or more corresponding IMRs for each CMR. That is, one CMR can be mapped to one or more IMRs. The electronic device 100 can use each of the K transmit beams to send a downlink signal to the user equipment, and the user equipment can use the same receive beam to receive the downlink signal to determine the signal-to-interference-and-noise ratio between each transmit beam and the receive beam. As a result, the user equipment can reflect the interference situation when calculating the channel quality between the transmit beam and the receive beam, allowing the network-side equipment and the user equipment to more reasonably select the transmit beam and receive beam.

[0075] According to an embodiment of the present disclosure, the configuration unit 110 may configure N IMRs and, for each IMR, one or more corresponding CMRs. These one or more CMRs correspond to the same transmit beam, where N is an integer greater than or equal to 1. Here, the one or more CMRs corresponding to each IMR are identical and correspond to the same transmit beam. Since CMRs represent channel measurement resources and transmit beams represent the direction in which a beam is transmitted, one or more CMRs corresponding to the same transmit beam means that downlink signals are transmitted in the same beam direction using one or more channel measurement resources.

[0076] Figure 4 Schematic diagram showing the P3 process according to the prior art. Figure 4 As shown in Figure 3, during the P3 process, the network device uses a single transmit beam to send downlink signals to the user device, and the user device uses multiple receive beams to receive the downlink signals. The user device can then calculate the channel quality between the transmit beam and each receive beam, thereby determining the appropriate receive beam for data transmission. Figure 4 The diagram shows a case where the user equipment has multiple receiving beams, but the user equipment may also have only one receiving beam.

[0077] Figure 5 : is a schematic diagram showing the configuration of CMR and IMR in the P3 process according to an embodiment of the present disclosure. Figure 5 As shown, configuration unit 110 configures N IMRs and Q CMRs for each IMR, where N is a positive integer and Q is a positive integer. The Q CMRs configured for each of the N IMRs are identical, i.e., the Q CMRs corresponding to the first IMR, the Q CMRs corresponding to the second IMR, ..., and the Q CMRs corresponding to the Nth IMR are all identical. Furthermore, these Q CMRs all correspond to the same transmit beam, i.e., the transmit beam used by the network-side device during this process.

[0078] According to an embodiment of the present disclosure, Q can be equal to the number of receive beams of the user device. Since the user device uses Q receive beams to receive downlink signals from the same transmit beam of the electronic device 100, Q CMRs can be used to send downlink signals in the same transmit beam direction, corresponding one-to-one to the Q receive beams of the user device. Furthermore, since each of the Q CMRs corresponds to the same transmit beam direction, they also correspond to the same N IMRs. That is, from the perspective of the IMRs, each of the N IMRs corresponds to the same Q CMRs.

[0079] According to an embodiment of the present disclosure, the electronic device 100 can transmit a downlink signal to a user equipment (UE) using the same transmit beam via the communication unit 130. The UE then receives the downlink signal using each of one or more receive beams. Furthermore, for any receive beam, the UE determines the signal power based on the signal quality measured on one or more CMRs, and the interference power based on the signal quality measured on all or some of the N IMRs. Furthermore, the UE determines the signal-to-interference-plus-noise ratio (SINR) between the transmit beam and the receive beam based on the signal power and the interference power. In this manner, the UE can determine the SINR between the transmit beam and each receive beam.

[0080] For example, for the first receiving beam, the user equipment may determine the signal power between the transmitting beam and the first receiving beam of the user equipment based on the signal qualities measured on the Q CMRs, and determine the interference power between the transmitting beam and the first receiving beam of the user equipment based on the signal qualities measured on all or part of the N IMRs. Then, the signal-to-interference-and-noise ratio between the transmitting beam and the first receiving beam of the user equipment is determined based on the measured signal power and interference power.

[0081] Similarly, for the second receive beam, the user equipment may determine the signal power between the transmit beam and the second receive beam of the user equipment based on the signal qualities measured on the Q CMRs, and determine the interference power between the transmit beam and the second receive beam of the user equipment based on the signal qualities measured on all or some of the N IMRs. Subsequently, the user equipment may determine the signal-to-interference-plus-noise ratio between the transmit beam and the second receive beam of the user equipment based on the measured signal power and interference power. Thus, in a similar manner, the user equipment may determine the signal-to-interference-plus-noise ratio between the transmit beam and each of one or more receive beams of the user equipment.

[0082] According to an embodiment of the present disclosure, the configuration unit 110 may configure N IMRs through RRC signaling, so that the user equipment determines the interference power based on the signal quality measured on all of the N IMRs. For example, for the first receive beam, the user equipment may determine the interference power between the transmit beam and the first receive beam of the user equipment based on the signal quality measured on all of the N IMRs.

[0083] According to an embodiment of the present disclosure, the configuration unit 110 may configure N IMRs through RRC signaling, and activate one or more of the N IMRs through MAC signaling, such as MAC CE or DCI, so that the user equipment determines the interference power based on the signal quality measured on the activated IMRs. For example, assuming that the configuration unit 110 activates the first and third IMRs of the N IMRs, the user equipment may determine the interference power between the transmit beam and each receive beam of the user equipment based on the signal quality measured on the first and third IMRs of the N IMRs.

[0084] According to an embodiment of the present disclosure, the electronic device 100 may receive signal-to-interference-plus-noise ratio information from the user equipment through the communication unit 130. The signal-to-interference-plus-noise ratio information includes a signal-to-interference-plus-noise ratio between a transmit beam and one or more receive beams.

[0085] According to an embodiment of the present disclosure, the determining unit 140 may determine the signal to interference plus noise ratio between the transmit beam and one or more receive beams according to the signal to interference plus noise ratio information.

[0086] According to an embodiment of the present disclosure, the signal-to-interference-and-noise ratio information may include a single signal-to-interference-and-noise ratio, for example, if the user equipment reports only the maximum value among all signal-to-interference-and-noise ratios. The signal-to-interference-and-noise ratio information may also include multiple signal-to-interference-and-noise ratios, for example, if the user equipment reports both the maximum and minimum values ​​among all signal-to-interference-and-noise ratios.

[0087] According to an embodiment of the present disclosure, because the user equipment determines the interference power based on all or some of the activated IMRs among the N IMRs, the electronic device 100 is aware in advance of the IMRs for which the signal to interference plus noise ratio is intended. Therefore, the signal to interference plus noise ratio information only needs to include the signal to interference plus noise ratio value. Table 3 shows an example of signal to interference plus noise ratio information received by the electronic device 100.

[0088] Table 3

[0089] Signal-to-interference-and-noise ratio (SINR) The first signal-to-interference-and-noise ratio SINR1 … … Pth signal-to-interference-and-noise ratio SINRP

[0090] Alternatively, according to an embodiment of the present disclosure, the user equipment may also select some IMRs from the N IMRs to determine the interference power. In this case, the electronic device 100 does not know the IMR to which each signal to interference and noise ratio value corresponds. Therefore, the signal to interference and noise ratio information may further include identification information of one or more IMRs to which each signal to interference and noise ratio corresponds.

[0091] According to an embodiment of the present disclosure, because the user equipment can select some IMRs from N IMRs to determine interference power, the user equipment can determine multiple signal-to-interference-and-noise ratio values ​​for a single receive beam based on different IMR combinations. For example, when using the first receive beam to receive a downlink signal, the user equipment can select the first and second IMRs from the N IMRs to calculate a signal-to-interference-and-noise ratio value, or select the third IMR to calculate another signal-to-interference-and-noise ratio value. It is assumed here that N is an integer greater than or equal to 3. Thus, the signal-to-interference-and-noise ratio information received by the electronic device 100 may include one or more signal-to-interference-and-noise ratios for a single receive beam. It is worth noting that although the user equipment can calculate one or more signal-to-interference-and-noise ratio values ​​for a single receive beam, the user equipment is not required to report the receive beam for which the signal-to-interference-and-noise ratio value is intended.

[0092] Table 4 shows an example of signal-to-interference-and-noise ratio information received by the electronic device 100 .

[0094]

[0095]

[0096] According to an embodiment of the present disclosure, the coordination unit 150 can determine a transmit beam for transmitting downlink data to other user equipment based on signal-to-interference-and-noise ratio information from the user equipment. For example, when the signal-to-interference-and-noise ratio information received by the electronic device 100 indicates that the signal-to-interference-and-noise ratio of the user equipment is relatively low under the influence of IMR2 and IMR3 (in this case, the electronic device 100 does not know which receive beam the user equipment uses to achieve a relatively low signal-to-interference-and-noise ratio under the influence of IMR2 and IMR3), the electronic device 100 can avoid using IMR2 and IMR3 to transmit downlink data to other user equipment to reduce interference to the user equipment. For another example, when the signal-to-interference-and-noise ratio information received by the electronic device 100 indicates that the signal-to-interference-and-noise ratio of the user equipment is relatively high under the influence of IMR1 (in this case, the electronic device 100 does not know which receive beam the user equipment uses to achieve a relatively high signal-to-interference-and-noise ratio under IMR1), the electronic device 100 can avoid using IMR1 to transmit downlink data to other user equipment because using IMR1 to transmit downlink data to other user equipment will cause less interference to the user equipment.

[0097] In the traditional P3 process, the user equipment does not need to report the measurement results in this process, but only needs to determine the appropriate receiving beam based on the measurement results. According to the implementation of the present disclosure, in the P3 process, the electronic device 100 can configure N IMRs and configure one or more corresponding CMRs for each IMR. That is, one IMR can be mapped to one or more CMRs. The electronic device 100 can use the same transmit beam to send a downlink signal to the user equipment, and the user equipment can use different receive beams to receive the downlink signal to determine the signal to interference and noise ratio between the transmit beam and each receive beam. As a result, the user equipment can reflect the interference situation when calculating the channel quality between the transmit beam and the receive beam. Furthermore, the user equipment can feed back the signal to interference and noise ratio information to the electronic device 100, so that the electronic device 100 and the user equipment can more reasonably select the transmit beam and the receive beam.

[0098] Thus, according to the embodiments of the present disclosure, the electronic device 100 can be configured with one or more CMRs and one or more IMRs. Furthermore, according to the embodiments of the present disclosure, different CMR and IMR configurations can be set for the P2 process and the P3 process, so that the user equipment determines the signal power based on the signal quality measured on the CMR and the interference power based on the signal quality measured on the IMR, thereby determining the signal-to-interference-and-noise ratio between the transmit beam and the receive beam. Thus, when the user equipment calculates the channel quality between the transmit beam and the receive beam, it can reflect the interference situation and feed back the signal-to-interference-and-noise ratio information to the electronic device 100. This allows the electronic device 100 and the user equipment to more reasonably select the transmit beam and receive beam.

[0099] <2. User Equipment Configuration Example>

[0100] Figure 6 1 is a block diagram showing the structure of an electronic device 600 used as a user equipment in a wireless communication system according to an embodiment of the present disclosure. Figure 6 As shown, the electronic device 600 may include a communication unit 610 , a processing unit 620 , and a computing unit 630 .

[0101] Here, each unit of electronic device 600 may be included in a processing circuit. It should be noted that electronic device 600 may include either one processing circuit or multiple processing circuits. Furthermore, the processing circuit may include various discrete functional units to perform various functions and / or operations. It should be noted that these functional units may be physical entities or logical entities, and units with different names may be implemented by the same physical entity.

[0102] According to an embodiment of the present disclosure, the electronic device 600 can receive downlink signals of transmit beams corresponding to one or more CMRs from the network side device using a receive beam via the communication unit 610. Here, the network side device is configured with one or more CMRs and one or more IMRs.

[0103] According to an embodiment of the present disclosure, the processing unit 620 may control the execution of the beam scanning process. For example, during the P2 process, the processing unit 620 may control the electronic device 600 to use the same receive beam to receive downlink signals from each of the multiple transmit beams of the network-side device. For another example, during the P3 process, the processing unit 620 may control the electronic device 600 to use each of the one or more receive beams to receive downlink signals from the same transmit beam of the network-side device.

[0104] According to an embodiment of the present disclosure, the calculation unit 630 may calculate the signal-to-interference-and-noise ratio between the transmit beam of the network-side device and the receive beam of the electronic device 600. Specifically, the calculation unit 630 may determine the signal power based on the signal quality measured on the CMR, determine the interference power based on the signal quality measured on the IMR, and determine the signal-to-interference-and-noise ratio between the transmit beam and the receive beam based on the signal power and the interference power.

[0105] Thus, according to the embodiment of the present disclosure, the electronic device 600 can use a receive beam to receive downlink signals, determine signal power based on the signal quality measured on the CMR, and determine interference power based on the signal quality measured on the IMR, thereby determining the signal-to-interference-and-noise ratio between the transmit beam and the receive beam. Thus, when calculating the channel quality between the transmit beam and the receive beam, the interference situation can be reflected, allowing the network-side device and the electronic device 600 to more reasonably select the transmit beam and the receive beam.

[0106] According to an embodiment of the present disclosure, the processing unit 620 can control the execution of the beam scanning process so that the electronic device 600 can use the same receiving beam to receive the downlink signal of each of the K transmitting beams from the network side device through the communication unit 610, where K is an integer greater than 1.

[0107] Here, the network-side device is configured with K CMRs corresponding to the K transmit beams, and each CMR is configured with one or more corresponding IMRs. The specific configuration has been described in detail above and will not be repeated here. As described above, electronic device 600 can adopt this reception method during the P2 process.

[0108] According to an embodiment of the present disclosure, the CMR and one or more IMRs corresponding to the CMR are in a quasi-co-located QCL type D relationship, so the electronic device 600 can receive the CMR and one or more IMRs corresponding to the CMR using the same receiving beam through the communication unit 610.

[0109] According to an embodiment of the present disclosure, the calculation unit 630 may determine the signal power between the transmit beam and the receive beam based on the signal quality measured on the CMR corresponding to the transmit beam. For example, for the first transmit beam corresponding to the first CMR, the calculation unit 630 may determine the signal power between the first transmit beam and the receive beam of the electronic device 600 based on the signal quality measured on the first CMR.

[0110] According to an embodiment of the present disclosure, the calculation unit 630 may determine the interference power between the transmit beam and the receive beam based on the signal quality measured on all or part of the IMRs corresponding to the CMR. For example, for the first transmit beam corresponding to the first CMR, the calculation unit 630 may determine the interference power between the first transmit beam and the receive beam of the electronic device 600 based on the signal quality measured on all or part of the M1 IMRs corresponding to the first CMR. According to an embodiment of the present disclosure, the calculation unit 630 may accumulate the signal quality measured on all or part of the M1 IMRs to determine the interference power between the first transmit beam and the receive beam of the electronic device 600.

[0111] According to an embodiment of the present disclosure, the calculation unit 630 can determine the signal-to-interference-plus-noise ratio (SINR) between the transmit beam and the receive beam based on the signal power between the transmit beam and the receive beam and the interference power between the transmit beam and the receive beam. Specifically, the calculation unit 630 can calculate the SINR value according to the formula S / (I+N), where S represents the signal power between the transmit beam and the receive beam, I represents the interference power between the transmit beam and the receive beam, and N represents the receiver noise power of the electronic device 600. In addition, the SINR discussed in the present disclosure refers to the SINR at the physical layer (or layer 1, L1, Lay1), and is therefore also referred to as L1-SINR (Signal to Interference plus Noise Ratio). In the present disclosure, the calculation unit 630 can use RSRP, etc. to represent the signal quality, or other parameters to represent the signal quality, and the present disclosure is not limited to this.

[0112] Similarly, for the second transmit beam corresponding to the second CMR, the calculation unit 630 may determine the signal power between the second transmit beam and the receive beam of the electronic device 600 based on the signal quality measured on the second CMR, determine the interference power between the second transmit beam and the receive beam of the electronic device 600 based on the signal quality measured on all or part of the M2 IMRs corresponding to the second CMR, and determine the signal-to-interference-plus-noise ratio between the second transmit beam and the receive beam of the electronic device 600 based on the measured signal power and interference power. Thus, in a similar manner, the calculation unit 630 may determine the signal-to-interference-plus-noise ratio between each of the K transmit beams and the receive beam of the electronic device 600.

[0113] Here, the signal-to-interference-and-noise ratio (SINR) is a value calculated for a specific CMR, a specific receive beam, and a specific IMR. For example, for the first CMR, the SINR value calculated by the calculation unit 630 represents the SINR obtained when the network-side device uses the first transmit beam to transmit downlink signals, the electronic device 600 uses the same receive beam to receive downlink signals, and all or part of the M1 IMRs are affected. In addition, since there is a one-to-one correspondence between transmit beams and CMRs, it can also be said that the SINR is a value calculated for a specific transmit beam, a specific receive beam, and a specific IMR.

[0114] According to an embodiment of the present disclosure, the electronic device 600 may obtain one or more IMRs corresponding to each CMR through RRC signaling. Further, the calculation unit 630 may determine the interference power between the transmit beam corresponding to the CMR and the receive beam of the electronic device 600 based on the signal quality measured on all IMRs corresponding to the CMR.

[0115] According to an embodiment of the present disclosure, the electronic device 600 may also obtain one or more IMRs configured for each CMR through RRC signaling, and obtain one or more activated IMRs among the IMRs corresponding to each CMR through MAC signaling, such as MAC CE or DCI. Furthermore, the calculation unit 630 may determine the interference power between the transmit beam corresponding to the CMR and the receive beam of the electronic device 600 based on the signal quality measured on the activated IMR corresponding to the CMR.

[0116] According to the embodiments of the present disclosure, Figure 6 As shown, the electronic device 600 may further include a generating unit 640 for generating signal to interference and noise ratio information. Furthermore, the electronic device 600 may send the signal to interference and noise ratio information to the network side device via the communication unit 610.

[0117] According to an embodiment of the present disclosure, the signal-to-interference-and-noise ratio information generated by the generation unit 640 may include the signal-to-interference-and-noise ratio between one or more transmit beams and a receive beam among the K transmit beams. Here, the signal-to-interference-and-noise ratio information generated by the generation unit 640 may include a single signal-to-interference-and-noise ratio. For example, the signal-to-interference-and-noise ratio information may include only the signal-to-interference-and-noise ratio with the largest value calculated by the calculation unit 630. The signal-to-interference-and-noise ratio information generated by the generation unit 640 may also include multiple signal-to-interference-and-noise ratios. For example, the signal-to-interference-and-noise ratio information may include the signal-to-interference-and-noise ratios with the largest and smallest values ​​calculated by the calculation unit 630.

[0118] According to an embodiment of the present disclosure, the signal to interference plus noise ratio information generated by the generating unit 640 may further include identification information of the CMR to which each signal to interference plus noise ratio is directed. That is, the signal to interference plus noise ratio information may be as shown in Table 1 above.

[0119] In the above embodiment, the calculation unit 630 determines the interference power between the transmit beam corresponding to the CMR and the receive beam of the electronic device 600 based on the signal quality measured on all IMRs or some activated IMRs corresponding to the CMR, and the network side device knows all IMRs or activated IMRs corresponding to each CMR. Therefore, the network side device only needs to obtain the CMR identifier to know the IMR for which the signal to interference and noise ratio is targeted.

[0120] According to an embodiment of the present disclosure, the electronic device 600 may also obtain one or more IMRs corresponding to each CMR configured through RRC signaling, and the calculation unit 630 may select one or more IMRs from the IMRs corresponding to each CMR, and may determine the interference power based on the signal quality measured on the selected IMRs. For example, for the first transmit beam corresponding to the first CMR, assuming that the calculation unit 630 selects the first IMR and the third IMR from the M1 IMRs corresponding to the first CMR, the calculation unit 630 may determine the interference power between the first transmit beam and the receive beam of the electronic device 600 based on the signal quality measured on the first IMR and the third IMR. It is assumed here that M1 is an integer greater than or equal to 3.

[0121] According to an embodiment of the present disclosure, the calculation unit 630 can calculate multiple signal-to-interference-and-noise ratios (SINRs) for the same transmit beam. For example, for the first transmit beam corresponding to the first CMR, the calculation unit 630 selects the first and third IMRs from the M1 IMRs corresponding to the first CMR, determines interference power based on the signal quality measured on the first and third IMRs, and thereby calculates a SINR between the first transmit beam and the receive beam of the electronic device 600. The calculation unit 630 can also select the fifth IMR from the M1 IMRs corresponding to the first CMR, determine interference power based on the signal quality measured on the fifth IMR, and thereby calculate another SINR between the first transmit beam and the receive beam of the electronic device 600. It is assumed herein that M1 is an integer greater than or equal to 5.

[0122] In the above embodiment, because the calculation unit 630 determines the interference power between the transmit beam corresponding to the CMR and the receive beam of the electronic device 600 based on the signal quality measured on the selected IMR from all IMRs corresponding to the CMR, and the network-side device is unaware of the IMR selected by the calculation unit 630, the signal-to-interference-and-noise ratio information generated by the generation unit 640 may further include identification information of one or more IMRs for each signal-to-interference-and-noise ratio. In other words, the signal-to-interference-and-noise ratio information may be as shown in Table 2 above.

[0123] According to an embodiment of the present disclosure, the generation unit 640 may also pre-map different IMR combinations to index values, so that the index values ​​can be used to indicate one or more IMRs for which the signal-to-interference-and-noise ratio is to be calculated. For example, index 0 indicates IMR1+IMR2, index 1 indicates IMR1+IMR3, and so on. When the calculation unit 630 selects IMR1 and IMR2 from the M1 IMRs corresponding to the first CMR to calculate the signal-to-interference-and-noise ratio, the generation unit 640 may use index 0 to indicate that the IMRs for which the signal-to-interference-and-noise ratio is to be calculated are IMR1 and IMR2.

[0124] As described above, during the P2 process, the network-side device can configure K CMRs corresponding one-to-one to the K transmit beams, and configure one or more corresponding IMRs for each CMR. That is, one CMR can be mapped to one or more IMRs. The network-side device can use each of the K transmit beams to send a downlink signal to the electronic device 600, and the electronic device 600 can use the same receive beam to receive the downlink signal to determine the signal-to-interference-and-noise ratio between each transmit beam and the receive beam. As a result, the electronic device 600 can reflect the interference situation when calculating the channel quality between the transmit beam and the receive beam, so that the network-side device can more reasonably select the transmit beam. For example, the network-side device can select a transmit beam with a larger signal-to-interference-and-noise ratio to send downlink information to the electronic device 600.

[0125] According to an embodiment of the present disclosure, the processing unit 620 can control the execution of the beam scanning process so that the electronic device 600 receives the downlink signal of the same transmit beam from the network side device through the communication unit 610 using each of one or more receive beams.

[0126] Here, the network-side device is configured with N IMRs, each of which is configured with one or more corresponding CMRs. The one or more CMRs correspond to the same transmit beam, and N is an integer greater than or equal to 1. The specific configuration has been described in detail above and will not be repeated here. As described above, electronic device 600 can adopt this reception method during the P3 process.

[0127] According to an embodiment of the present disclosure, for each receive beam, the calculation unit 630 can determine the signal power between the transmit beam and the receive beam based on the signal quality measured on one or more CMRs. Here, the calculation unit 630 can determine the signal power based on the signal quality measured on any one or more CMRs. For example, the calculation unit 630 can select any one CMR from the one or more CMRs and determine the signal power based on the signal quality measured on the CMR. For another example, the calculation unit 630 can also determine the signal power based on the accumulation of signal qualities measured on multiple CMRs.

[0128] According to an embodiment of the present disclosure, for each receive beam, the calculation unit 630 may determine the interference power between the transmit beam and the receive beam according to signal qualities measured on all or part of the N IMRs.

[0129] According to an embodiment of the present disclosure, for each receive beam, the calculation unit 630 can determine the signal-to-interference-and-noise ratio (SINR) between the transmit beam and the receive beam based on the signal power and the interference power. As described above, the calculation unit 630 can calculate the SINR based on the formula S / (I+N), where S is the signal power between the transmit beam and the receive beam, I is the interference power between the transmit beam and the receive beam, and N is the receiver noise power of the electronic device 600.

[0130] As described above, the calculation unit 630 may calculate the signal-to-interference-and-noise ratio between the transmit beam and each receive beam.

[0131] According to an embodiment of the present disclosure, the electronic device 600 can obtain N IMRs configured by the network side device through RRC signaling. Further, the calculation unit 630 can determine the interference power between the transmit beam and each receive beam based on the signal quality measured on all IMRs in the N IMRs.

[0132] According to an embodiment of the present disclosure, the electronic device 600 may also obtain N IMRs configured by the network-side device through RRC signaling, and obtain one or more activated IMRs among the N IMRs through MAC signaling, such as MAC CE or DCI. Furthermore, the calculation unit 630 may determine the interference power between the transmit beam and each receive beam based on the signal quality measured on the activated IMRs.

[0133] According to an embodiment of the present disclosure, the signal-to-interference-and-noise ratio (SINR) information generated by the generation unit 640 may include the SINR between a transmit beam and one or more receive beams. Here, the SINR information generated by the generation unit 640 may include a single SINR. For example, the SINR information may include only the SINR with the largest SINR value calculated by the calculation unit 630. The SINR information generated by the generation unit 640 may also include multiple SINRs. For example, the SINR information may include the SINRs with the largest and smallest SINR values ​​calculated by the calculation unit 630. In other words, the SINR information may be as shown in Table 3 above.

[0134] In the foregoing embodiment, the calculation unit 630 determines the interference power between the transmit beam and the receive beam of the electronic device 600 based on the signal qualities measured on all IMRs or activated IMRs among the N IMRs, and the network-side device knows the N IMRs or activated IMRs. Therefore, the network-side device only needs to obtain the signal-to-interference-plus-noise ratio to know the IMR to which the signal-to-interference-plus-noise ratio is directed.

[0135] According to an embodiment of the present disclosure, the electronic device 600 may also obtain N IMRs configured by the network-side device through RRC signaling. In addition, for any receive beam, the calculation unit 630 may also select one or more IMRs from the N IMRs, and determine the interference power between the transmit beam and the receive beam based on the signal quality measured on the selected IMRs. According to an embodiment of the present disclosure, the calculation unit 630 may select different IMRs for different receive beams. For example, for the first receive beam, the calculation unit 630 may select the second and fourth IMRs from the N IMRs to calculate the interference power and signal to interference and noise ratio. For the second receive beam, the calculation unit 630 may select the fifth IMR from the N IMRs to calculate the interference power and signal to interference and noise ratio. It is assumed here that N is an integer greater than or equal to 5.

[0136] According to an embodiment of the present disclosure, the calculation unit 630 can calculate multiple signal-to-interference-and-noise ratios (SINRs) for the same receive beam. For example, for the first receive beam, the calculation unit 630 selects the first and third IMRs from the N IMRs, determines interference power based on the signal quality measured on the first and third IMRs, and thereby calculates a SINR between the transmit beam and the first receive beam of the electronic device 600. The calculation unit 630 can also select the fifth IMR from the N IMRs, determine interference power based on the signal quality measured on the fifth IMR, and thereby calculate another SINR between the transmit beam and the first receive beam of the electronic device 600. It is assumed herein that N is an integer greater than or equal to 5.

[0137] According to an embodiment of the present disclosure, because the calculation unit 630 determines the interference power between the transmit beam and the receive beam of the electronic device 600 based on the signal quality measured on the selected IMR among the N IMRs, and the network-side device is unaware of the IMR selected by the calculation unit 630, the signal-to-interference-and-noise ratio information generated by the generation unit 640 may further include identification information of one or more IMRs for each signal-to-interference-and-noise ratio. In other words, the signal-to-interference-and-noise ratio information may be as shown in Table 4 above.

[0138] According to an embodiment of the present disclosure, the generation unit 640 may also pre-map different IMR combinations to index values, so that the index values ​​can be used to represent one or more IMRs for which the signal to interference and noise ratio is to be calculated. For example, index 0 represents IMR1+IMR2, index 1 represents IMR1+IMR3, etc. When the calculation unit 630 selects IMR1 and IMR2 to calculate the signal to interference and noise ratio, the generation unit 640 may use index 0 to indicate that the IMRs for which the signal to interference and noise ratio is to be calculated are IMR1 and IMR2.

[0139] As described above, in the signal to interference plus noise ratio information, an index value may be used to indicate the IMR to which the signal to interference plus noise ratio refers, thereby reducing signaling overhead.

[0140] As described above, during the P3 process, the signal-to-interference-and-noise ratio (SINR) information reported by the electronic device 600 to the network device may include the SINR value and, optionally, the IMR for which the SINR is targeted. In a conventional P3 process, the electronic device 600 does not report any measurement information to the network device. However, according to an embodiment of the present disclosure, the electronic device 600 may report SINR information to the network device, thereby enabling the network device to coordinate the transmit beam used to send downlink information to other user equipment based on the reported SINR information. For example, when the SINR information indicates that the SINR of the electronic device 600 is relatively low under IMR2 and IMR3 (in this case, the network device does not know which receive beam the electronic device 600 uses to achieve the lowest SINR under IMR2 and IMR3), the network device may avoid using IMR2 and IMR3 to send downlink data to other user equipment to reduce interference with the electronic device 600. For another example, when the signal-to-interference-and-noise ratio information indicates that the signal-to-interference-and-noise ratio of the electronic device 600 is relatively large under the action of IMR1 (at this time, the network-side device does not know which receive beam the electronic device 600 uses to produce a relatively large signal-to-interference-and-noise ratio under the action of IMR1), the network-side device may use IMR1 as much as possible to send downlink data to other user equipment, because using IMR1 to send downlink data to other user equipment causes less interference to the electronic device 600.

[0141] According to the embodiments of the present disclosure, Figure 6 As shown, the electronic device 600 may further include a coordination unit 650 configured to select an appropriate receiving beam according to the measurement result of the P3 process. For example, the coordination unit 650 may select a receiving beam with a relatively large signal-to-interference-noise ratio as the receiving beam for receiving downlink information.

[0142] As described above, during the P3 process, the network-side device can configure N IMRs and configure one or more corresponding CMRs for each IMR. In other words, one IMR can be mapped to one or more CMRs. The network-side device can use the same transmit beam to send downlink signals to the electronic device 600, and the electronic device 600 can use different receive beams to receive downlink signals to determine the signal-to-interference-and-noise ratio between the transmit beam and each receive beam. As a result, the electronic device 600 can reflect the interference situation when calculating the channel quality between the transmit beam and the receive beam. Furthermore, the electronic device 600 can feed back the signal-to-interference-and-noise ratio information to the network-side device, so that the network-side device and the electronic device 600 can more reasonably select the transmit beam and receive beam.

[0195] Each of the antennas 1210 includes a single or multiple antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used for the base station device 1220 to transmit and receive wireless signals. Figure 12 As shown, the eNB 1200 may include multiple antennas 1210. For example, the multiple antennas 1210 may be compatible with multiple frequency bands used by the eNB 1200.
