Description

Antenna switching processing method, communication node and storage medium

[0002] The present application relates to the field of wireless communication technology, for example, to a processing method for antenna switching, a communication node and a storage medium. Background Art

[0003] During antenna switching (reference signal rotation), since some frequency bands share or partially share antenna ports, when antenna switching is performed on a certain frequency band, the related frequency bands of the shared antenna ports also need to be switched together, which usually leads to interruption of reference signal transmission. However, in some cases, there are antenna ports in this frequency band that are not shared or do not need to be switched. For example, a frequency band has two transmit ports, one of which is affected by antenna switching, while the other is not affected and can continue to be used for transmission. In this case, since the network side cannot obtain the antenna switching capability information, it cannot flexibly configure the antenna switching during the antenna switching, blindly interrupting the transmission and affecting the reliability of the antenna switching.

[0029] The present application is described below in conjunction with the accompanying drawings and embodiments. It will be understood that the specific embodiments described herein are merely intended to explain the present application and are not intended to limit the present application. It should be noted that, unless there is a conflict, the embodiments and features within the embodiments of the present application may be combined with each other in any manner. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present application, not all structures.

[0030] When reference signal antenna switching (i.e., reference signal rotation) is performed, the related uplink transmission or downlink reception is usually interrupted. The reference signal can be, for example, a sounding reference signal (SRS). However, in practical applications, a common scenario is that the reference signal antenna switching only interrupts the receive antenna port or transmit antenna port (MIMO-Rx / Tx) of a certain multiple-input multiple-output (MIMO) system in a certain frequency band. For example, in the non-standalone (NSA) B3+n41 or New Radio Carrier Aggregation (NR CA) n3+n41 usage scenario, n3 can support 4-layer MIMO. When n41 performs SRS rotation, only one port of B3 is affected, while the other three ports can receive normally. In this case, the network-side node cannot know whether each port of the user equipment (UE) is affected or whether it can receive normally, so it cannot perform flexible configuration and scheduling and can only interrupt the transmission of the reference signal.

[0031] Similarly, for the uplink, since some bands share or partially share uplink transmit antenna ports, when performing uplink SRS antenna switching on a certain band, the related bands of the shared antenna ports also need to be switched together, resulting in uplink transmission interruption. Specifically, for this band, if all uplink antenna ports are switched, the uplink transmission will be interrupted; while for some scenarios where uplink transmit antenna ports are partially reused, the uplink transmission of some bands may not be interrupted. In this case, a low number of MIMO layers can be used. For example, there are 2 transmit ports, one of which is affected by the SRS antenna switching, and the other antenna port can be used for transmission. Although the UE has the ability to continue transmission, the network side cannot know this ability and blindly interrupts the transmission, affecting the efficiency and reliability of the reference signal antenna switching.

[0032] Taking the R15 functionality (maximum 4 Tx) as an example, for a frequency band combination containing bands A / B / C, BC1 = Band A + Band B + Band C. Table 1 shows the association between the frequency bands during SRS antenna switching. As shown in Table 1, when SRS antenna switching is performed, the uplink (transmit) antennas of bands A and B are switched simultaneously, meaning that bands A and B share the same transmit antenna. For downlink, switching the transmit antenna of band A will also affect downlink reception on band B, which means that switching the transmit antenna of band B will also affect the downlink of band A.

[0033] Table 1 Correlation between frequency bands when switching SRS antennas

[0034] As you can see, both uplink bands A and B are reported as band A. Bands A and B form a frequency band group, and the identifier of this frequency band group is the lower-numbered band, i.e., band A. Uplink SRS antenna switching for band A will affect downlink reception for band B. Because bands A and B form a group, only A is required here, indicating that uplink SRS antenna switching for bands A and B within the group will affect downlink reception for band B.

[0035] The method provided in the embodiment of the present application is mainly to solve the above-mentioned problem. The UE can report to the network side the impact information of reference signal antenna switching (reference signal rotation) on the number of MIMO layers supported on each frequency band, including uplink impact information and / or downlink impact information.

[0036] Figure 1 is a flowchart of a method for processing antenna switching according to one embodiment. This method can be applied to a first communication node, which can be understood as a node that needs to report the capabilities of each antenna port during a reference signal antenna switching process, primarily a UE. As shown in Figure 1, the method provided in this embodiment includes steps 110 and 120.

[0037] In step 110, information on the impact of performing reference signal antenna switching on antenna ports supporting transmission in each frequency band is determined.

[0038] In step 120, the impact information corresponding to each of the frequency bands is reported.

[0039] In this embodiment, the impact information can be used to reflect whether each antenna port in the first communication node is affected by the reference signal antenna switching, or whether each antenna port supports continued transmission of signals, data, signaling and other information. By reporting the impact information to the second communication node, the second communication node can be informed of the capabilities of the first communication node, thereby flexibly configuring and scheduling each antenna port of the first communication node.

[0040] In one embodiment, for any frequency band, the impact information includes: first information of antennas in the frequency band that are affected by reference signal antenna switching performed by other frequency bands.

[0041] For example, if reference signal antenna switching performed by band A affects band B, first information is reported to band B, that is, information about antennas in band B affected by reference signal antenna switching performed by band A.

[0042] In one embodiment, reporting the impact information corresponding to each frequency band includes: reporting the impact information corresponding to the frequency band when at least one antenna port in the frequency band is affected by reference signal antenna switching performed in other frequency bands.

[0043] In this embodiment, for any frequency band, the impact information includes: first information about antennas in the frequency band that are affected by reference signal antenna switching in other frequency bands. In this case, if at least one antenna port in a frequency band is affected by reference signal antenna switching in other frequency bands, the impact information corresponding to that frequency band is reported. For example, if reference signal antenna switching in band A affects at least one antenna port in band B, the first information is reported for band B.

[0044] In one embodiment, for downlink reception of a reference signal in any frequency band, the impact information includes: information of the frequency band affected by reference signal antenna switching performed on the frequency band, and first information of antennas affected in the frequency band affected by reference signal antenna switching performed on the frequency band.

[0045] For example, for downlink reception of the reference signal, band A performing reference signal antenna switching will affect band B. In this case, band A reports the information of band B affected by it, as well as the first information of the antenna in band B affected by band A performing reference signal antenna switching.

[0046] In one embodiment, the first information includes at least one of the following: affected antenna ports in the frequency band; unaffected antenna ports in the frequency band; the number of affected antenna ports in the frequency band; the number of unaffected antenna ports in the frequency band; the number of available antenna port layers in the frequency band; and the number of unavailable antenna port layers in the frequency band.

[0047] In one embodiment, for any frequency band, the impact information includes: second information of antennas of other frequency bands affected by reference signal antenna switching performed on the frequency band.

[0048] For example, if reference signal antenna switching performed by band A affects band B, band A reports second information, ie, information about antennas of band B affected by reference signal antenna switching performed by band A.

[0049] In one embodiment, reporting the impact information corresponding to each frequency band includes:

[0050] In a case where reference signal antenna switching performed on a frequency band affects at least one other frequency band, impact information corresponding to the frequency band is reported.

[0051] In this embodiment, for any frequency band, the impact information includes second information about antennas in other frequency bands affected by reference signal antenna switching in the frequency band. In this case, if reference signal antenna switching in one frequency band affects at least one other frequency band, the impact information corresponding to that frequency band is reported. For example, if reference signal antenna switching in band A affects band B, the second information for band A is reported.

[0052] In one embodiment, for uplink transmission of a reference signal in any frequency band, the impact information includes: information of a frequency band that performs reference signal antenna switching together with the frequency band, and second information of an affected antenna in the frequency band that performs reference signal antenna switching together with the frequency band.

[0053] For example, for the uplink transmission of the reference signal, when band A executes the reference signal, band B also needs to execute the reference signal antenna switching. In this case, band A reports the information of band B that needs to execute the reference signal antenna switching together with it, as well as the second information of the antenna in band B affected by the execution of the reference signal antenna switching.

[0054] In one embodiment, the second information includes at least one of the following: a frequency band affected by performing reference signal antenna switching; an antenna port affected in the frequency band; an antenna port not affected in the frequency band; the number of antenna ports affected in the frequency band; the number of antenna ports not affected in the frequency band; the number of antenna port layers affected in the frequency band; the number of antenna port layers not affected in the frequency band.

[0055] In one embodiment, reporting the impact information corresponding to each frequency band includes one of the following:

[0056] Report the impact information corresponding to each frequency band in the frequency band group;

[0057] Report the impact information corresponding to each frequency band.

[0058] In this embodiment, the reporting granularity may be reporting for each band in each frequency band group (ie, band combination), or reporting for an independent band list, that is, the impact information may be reported for each band without being restricted by the band combination.

[0059] In one embodiment, the method further comprises: for any frequency band,

[0060] Step 130: If there is an antenna port not affected by the reference signal antenna switching in the frequency band, transmit the signal, data, or signaling through the antenna port not affected by the reference signal antenna switching;

[0061] Step 140: When all antenna ports in the frequency band are affected by the reference signal antenna switching, interrupt the transmission of the signal, data, or signaling in the frequency band.

[0062] In this embodiment, if an antenna port in a frequency band is not affected by the reference signal antenna switching, the antenna port can continue to transmit signals, data, or signaling; otherwise, transmission is interrupted. This improves antenna port utilization, increases signal, data, or signaling transmission efficiency, and enhances the reliability of reference signal antenna switching.

[0063] FIG2 is a flowchart of a method for processing antenna switching according to an embodiment. This method can be applied to a second communication node, which can be a network-side node such as a base station or access point. It should be noted that technical details not fully described in this embodiment can be referred to in any of the above embodiments.

[0064] As shown in FIG. 2 , the method provided in this embodiment includes step 210 and step 220 .

[0065] In step 210, information on the impact of performing reference signal antenna switching on antenna ports supporting transmission in each frequency band is received.

[0066] In step 220, signals, data, or signaling are transmitted according to the impact information corresponding to each frequency band.

[0067] In this embodiment, the impact information can be used to reflect whether each antenna port in the first communication node is affected by the reference signal antenna switching, or whether each antenna port supports continued transmission of signals, data, signaling and other information. By receiving the impact information, the second communication node can accurately know the capabilities of the first communication node, thereby flexibly configuring and scheduling each antenna port of the first communication node to achieve efficient transmission of the reference signal and reliable reference signal antenna switching.

[0068] In one embodiment, for any frequency band, the impact information includes: first information of antennas in the frequency band that are affected by reference signal antenna switching performed by other frequency bands.

[0069] In one embodiment, receiving information about the impact of performing reference signal antenna switching on antenna ports supporting transmission in each frequency band includes:

[0070] In a case where at least one antenna port in the frequency band is affected by reference signal antenna switching performed in other frequency bands, impact information corresponding to the frequency band is received.

[0071] In one embodiment, for downlink reception of a reference signal in any frequency band, the impact information includes:

[0072] Information of a frequency band affected by reference signal antenna switching performed on the frequency band, and first information of antennas affected in the frequency band affected by reference signal antenna switching performed on the frequency band.

[0073] In one embodiment, the first information includes at least one of the following:

[0074] Frequency bands affected by performing reference signal antenna switching; antenna ports affected in the frequency band; antenna ports not affected in the frequency band; number of antenna ports affected in the frequency band; number of antenna ports not affected in the frequency band; number of antenna port layers available in the frequency band; number of antenna port layers not available in the frequency band.

[0075] In one embodiment, for any frequency band, the impact information includes: second information of antennas of other frequency bands affected by reference signal antenna switching performed on the frequency band.

[0076] In one embodiment, receiving information about the impact of performing reference signal antenna switching on antenna ports supporting transmission in each frequency band includes:

[0077] In a case where reference signal antenna switching performed on a frequency band affects at least one other frequency band, impact information corresponding to the frequency band is received.

[0078] In one embodiment, for uplink transmission of a reference signal in any frequency band, the impact information includes: information of the frequency band for which reference signal antenna switching is performed together with the frequency band, and second information of the antenna affected in the frequency band for which reference signal antenna switching is performed together with the frequency band.

[0079] In one embodiment, the second information includes at least one of the following: a frequency band affected by performing reference signal antenna switching; an antenna port affected in the frequency band; an antenna port not affected in the frequency band; the number of antenna ports affected in the frequency band; the number of antenna ports not affected in the frequency band; the number of antenna port layers affected in the frequency band; the number of antenna port layers not affected in the frequency band.

[0080] In one embodiment, receiving information on the impact of performing reference signal antenna switching on antenna ports supporting transmission in each frequency band includes one of the following:

[0081] receiving information on the impact of performing reference signal antenna switching on each frequency band in the frequency band group;

[0082] Information on the effect of performing reference signal antenna switching on each frequency band is received.

[0083] In one embodiment, transmitting a signal or data or signaling according to the impact information corresponding to each frequency band includes: for any frequency band,

[0084] When there is an antenna port not affected by the reference signal antenna switching in the frequency band, transmitting the signal or data or signaling through the antenna port not affected by the reference signal antenna switching;

[0085] In a case where all antenna ports in the frequency band are affected by the reference signal antenna switching, transmission of signals, data, or signaling in the frequency band is interrupted.

[0086] The antenna switching processing method of the present application is exemplified below through some specific embodiments. In the following embodiments, the first communication node is a UE, the second communication node is a network side, the reference signal is an SRS, and SRS antenna switching can also be understood as SRS rotation transmission.

[0087] Example 1

[0088] For the downlink of a certain band, when it is affected by the SRS antenna switching of certain bands, if only one or more antennas (ports) are affected for downlink reception, the UE can display or implicitly indicate the number of affected antennas (ports), for example, indicating the number of affected antennas (ports) or indicating the number of unaffected antenna ports.

[0089] Indicated options may include:

[0090] Solution 1: The UE indicates the affected band or band group (i.e., the band or band group for performing SRS antenna switching) and the affected antenna port status based on each affected downlink band;

[0091] Solution 2: The UE indicates the affected downlink band and the affected antenna port based on each affected band or band group.

[0092] After receiving the above indication, the network side can schedule the UE according to the number of affected antenna ports. In the scenario where only some downlink ports are affected, the UE's downlink data transmission can continue.

[0093] For scenario 1:

[0094] The UE indicates information about antenna ports of a certain band that are affected by certain band SRS antenna switching, and may indicate the number of antenna ports that are affected or not affected, or the number of antenna layers that can be used or not used when affected.

[0095] Scenario 1a: Different influencing bands or band groups have the same impact on the current band.

[0096] Figure 3 is a schematic diagram of impact information provided by an embodiment. As shown in Figure 3, taking the NR downlink scenario as an example, impact information can be reported for each band combination (BandCombination) in the band combination list (supportedBandCombinationList) that supports reference signal antenna switching. Each band in each band combination can be indicated by a band list (bandlist). Among them, maxBC is the total number of band combinations in the band combination list, and maxSimultaneousBands is the total number of bands in a band combination.

[0097] Taking the first band in the first band combination as an example, the reported impact information may include TxSwitch of the SRS antenna switching, including the first information (txSwitchImpactToRx) and the second information (txSwitchWithAnotherBand), txSwitchImpactToRx corresponds to the list of bands or band groups (ie, Aggressors) that exert influence, and the impact information may include the number of antenna ports (Ports number) or MIMO layers (layer) that are affected (Affected) and / or not affected (not affected); txSwitchWithAnotherBand corresponds to the impact information of other bands affected by the current band.

[0098] The coding example corresponding to Figure 3 is as follows:

[0099] The aggressor is an indication of an uplink band (or a band group) for performing uplink SRS switching that affects the downlink reception.

[0100] Table 2 shows the association between frequency bands during SRS antenna switching. As shown in Table 2, when SRS antenna switching is performed on band A or band B, downlink reception on band A is affected, for example, from four-layer reception to only two-layer reception. In this case, the UE can indicate the specific number of antenna ports that are affected or unaffected, or the number of antenna layers that can be used or unused when affected.

[0101] Table 2 Correlation between frequency bands when switching SRS antennas

[0102] It should be noted that a certain band may be affected by SRS antenna switching of multiple different bands; in addition, when affected by SRS antenna switching of different bands, the number of affected antenna ports may be the same.

[0103] Scenario 1b: Different influencing bands (or band groups) have different effects on the current band.

[0104] When a band is affected by SRS antenna switching for different bands, the number of antenna ports affected can be different. For example, when band A's downlink is affected by band B's SRS antenna switching, two downlink antenna ports are affected, while when band A's downlink is affected by band C's SRS antenna switching, only one antenna port is affected. The UE can indicate a different number of downlink antenna ports affected for each affected band (or band group).

[0105] Figure 4 is a schematic diagram of another type of impact information provided by an embodiment. As shown in Figure 4, taking the NR downlink scenario as an example, impact information can be reported for each band combination in the band combination list that supports reference signal antenna switching, and each band in each band combination can be indicated by the band list. Taking the first band in the first band combination as an example, the reported impact information may include TxSwitch for SRS antenna switching, including first information (txSwitchImpactToRx) and second information (txSwitchWithAnotherBand), txSwitchImpactToRx corresponds to a list of bands or band groups (i.e., aggressors) that exert influence, and the impact information may include, for each band or band group exerting influence (a total of m, where m can be an integer in the range of 1, 2, ... 32), the number of antenna ports (Ports number) or MIMO layers (layer) that are affected (Affected) and / or not affected (not affected); txSwitchWithAnotherBand corresponds to the impact information of other bands affected by the current band.

[0106] The coding example corresponding to Figure 4 is as follows:

[0107] Where aggressor indicates the uplink band (or band group) that affects downlink reception and the corresponding uplink SRS switching; affectedAntennaPorts indicates the number of downlink antenna ports affected (or the number of unaffected and usable antenna ports). If affectedAntennaPorts is not reported, it means that all antenna ports are affected. The situation corresponding to scenario 1b can be considered a special case of Figure 4.

[0108] Scenario 1c: For the affected band (or band group), the number of Tx antenna ports used for SRS antenna switching varies, resulting in inconsistent impacts on the current band. This means that the downlink impact varies for different numbers of uplink SRSTx antenna ports. In this case, the UE can report the corresponding downlink impact for different numbers of uplink antenna ports switched.

[0109] Figure 5 is a schematic diagram of another type of impact information provided by an embodiment. As shown in Figure 5, taking the NR downlink scenario as an example, impact information can be reported for each band combination in the band combination list that supports reference signal antenna switching, and each band in each band combination can be indicated by the band list. Among them, maxBC is the total number of band combinations in the band combination list, and maxSimultaneousBands is the total number of affected bands in a band combination. Taking the first band in the first band combination as an example, the reported impact information may include TxSwitch of SRS antenna switching, including the first information (txSwitchImpactToRx) and the second information (txSwitchWithAnotherBand). The impact information corresponding to txSwitchImpactToRx may include the number of antenna ports for different uplink antenna switching, the number of antenna ports (Ports number) or MIMO layers (layer) that are affected (Affected) and / or not affected (not affected); txSwitchWithAnotherBand corresponds to the impact information of other bands affected by the current band.

[0110] The coding example corresponding to Figure 5 is as follows:

[0111] Among them, "aggressor" indicates the uplink band (or band group) that affects the downlink reception and performs uplink SRS switching, that is, the affected band or band group; "affectedAntennaPorts" is the number of antenna ports affected for downlink reception (or the number of antenna ports that are not affected and can be used normally). When "affectedAntennaPorts" is not reported, it means that all antenna ports are affected. The solution in Figure 3 can be regarded as a special case of Figure 5; "srsTxPorts" is the number of Tx antenna ports for SRS antenna switching on the affected band or band group.

[0112] The number of antenna ports can be reported for each band combination (e.g., in scenarios 1a / 1b / 1c above, the reporting granularity is based on each band within the band combination), or it can be reported independently of the band combination, i.e., for each band, which can also be understood as reporting using a separate band list. For example, the UE can indicate the band list for SRS antenna switching and then report the corresponding capabilities for each affected band in the band list.

[0113] Taking scenario 1b as an example, Figure 6 is a schematic diagram of another type of impact information provided by an embodiment. As shown in Figure 6, instead of using a band combination list, the impact information corresponding to each band can be indicated through an independent band list (bandlist).

[0114] For scenario 2:

[0115] The UE indicates the antenna port affected by the downlink of a certain band. The content indicated in schemes 1 and 2 is essentially the same, but the indication methods are different.

[0116] Scenario 2a: When the current band performs SRS switching, the affected antenna ports on other affected downlink bands can be in the same state.

[0117] Figure 7 is a schematic diagram of another type of impact information provided by an embodiment. As shown in Figure 7, the main difference from Figure 3 is that the second information (txSwitchImpactToRx) corresponds to a list of bands or band groups affected by the current band. The impact information may include the number of antenna ports or MIMO layers affected and / or not affected in the bands affected by the current band; the first information (txSwitchWithAnotherBand) corresponds to the impact information of the band or band group that affects the current band.

[0118] The coding example corresponding to Figure 7 is as follows:

[0119] AffectedDLBand indicates the downlink band (or band group) affected by the uplink SRS switching of the current band.

[0120] Scenario 2b: When SRS switching is performed on the current band, the conditions of the affected antenna ports on other affected downlink bands may be inconsistent.

[0121] Figure 8 is a schematic diagram of another type of impact information provided by an embodiment. As shown in Figure 8, the main difference from Figure 4 is that the second information (txSwitchImpactToRx) corresponds to a list of bands or band groups affected by the current band. The impact information may include the number of affected and / or unaffected antenna ports or MIMO layers for each band affected by the current band. The first information (txSwitchWithAnotherBand) corresponds to the impact information of the band or band group that affects the current band. The affected antenna ports on each affected downlink band may be inconsistent.

[0122] The coding example corresponding to Figure 8 is as follows:

[0123] Among them, AffectedDLBand is an indication of the downlink band (or band group) that affects the uplink SRS switching of the current band; affectedAntennaPorts is the number of downlink receiving antenna ports affected (or the number of antenna ports that are not affected and can be used normally); when affectedAntennaPorts is not reported, it means that all antenna ports are affected.

[0124] Scenario 2c: When the SRS antenna is switched for the current band, the number of antenna ports affected for different downlink bands is different depending on the number of antenna ports used for SRS transmission.

[0125] Figure 9 is a schematic diagram of another type of impact information provided by an embodiment. As shown in Figure 9, the main difference from Figure 5 is that the second information (txSwitchImpactToRx) corresponds to a list of bands or band groups affected by the current band. The impact information may include the number of affected and / or unaffected antenna ports or MIMO layers for each band affected by the current band, for different numbers of antenna ports used for SRS transmission. The first information (txSwitchWithAnotherBand) corresponds to the impact information of the band or band group that affects the current band. The affected antenna ports on each affected downlink band can be inconsistent.

[0126] The coding example corresponding to Figure 9 is as follows:

[0127] Among them, AffectedDLBand indicates the downlink band (or band group) that affects the uplink SRS switching of the current band; affectedAntennaPorts is the number of downlink receiving antenna ports affected (or the number of unaffected antenna ports that can be used normally). When affectedAntennaPorts is not reported, it means that all antenna ports are affected. It should be noted that the solutions in Figure 7 and Scenario 2c can be regarded as special cases in Figure 9; srsTxPorts is the number of Tx antenna ports for SRS antenna switching on the affected band or band group.

[0128] Furthermore, the number of antenna ports can be indicated for each band combination (e.g., in scenarios 2a / 2b / 2c above, the reporting granularity is based on each band within the band combination), or it can be independent of the band combination, i.e., reported for each band, which can also be understood as reporting using a separate band list. For example, the UE can indicate the band list for SRS antenna switching and then report the corresponding capabilities for each affected band in the band list.

[0129] The number of antenna ports can also be reported independently of the existing capability reporting mechanism (i.e., the mechanism for reporting within each band combination. For example, in the scenarios shown in Figures 7-9 above, the reporting granularity is based on each band within the band combination). This can be done using a separate band list. That is, the UE indicates the band list for SRS antenna switching and then reports the corresponding capability for each affected band.

[0130] Example 2

[0131] For the uplink, this will cause some interruption of uplink transmission. For a certain band, if all uplink antenna ports are switched, the uplink will be interrupted. In some scenarios where uplink transmission antenna ports are partially reused, the uplink does not need to be interrupted, but a low number of MIMO layers can be used. For example, there are 2 transmission ports, one of which is affected by the SRS antenna switching, and the other antenna port can be used for transmission. In order to accurately indicate these capability information, the UE can indicate for a certain band whether it shares antenna ports with other bands. Taking into account that the shared ports between different Band combinations may be inconsistent, the indication schemes may include:

[0132] Solution 1: The UE indicates the affected band or band group (i.e., the band or band group for performing SRS antenna switching) and the affected antenna port status based on each affected uplink band;

[0133] Solution 2: The UE indicates, based on each affected band or band group, the uplink bands with which reference signal sweetheart switching needs to be performed and the affected antenna ports in these uplink bands.

[0134] After receiving the above instructions, the network side can perform scheduling accordingly. For scenarios where not all transmit antenna ports are affected, the uplink service can be sent without interruption using a low number of ports (or MIMO layers).

[0135] For scenario 1:

[0136] For the uplink of a certain band, when it is affected by SRS antenna switching of certain bands, if only one or more antennas (ports) of the uplink transmission are affected, the UE can explicitly or implicitly indicate the number of affected antennas (ports), for example, indicating the number of affected antennas (ports) or indicating the number of unaffected antenna ports.

[0137] Figure 10 is a schematic diagram of impact information provided by an embodiment. As shown in Figure 10, for the uplink scenario, impact information can be reported for each band combination in the band combination list that supports reference signal antenna switching, and each band in each band combination can be indicated by the band list. Among them, maxBC is the total number of band combinations in the band combination list, and maxSimultaneousBands is the total number of bands in a band combination. Taking the first band in the first band combination as an example, the reported impact information may include TxSwitch for SRS antenna switching, including the first information (txSwitchImpactToRx) and the second information (txSwitchWithAnotherBand). txSwitchImpactToRx corresponds to the impact information of other bands that have an impact on the current band, and txSwitchWithAnotherBand corresponds to the information of the band (Switch together UL band) that needs to perform SRS antenna switching together with the current band, as well as the information of the affected antennas in the band that needs to perform SRS antenna switching together with the current band.

[0138] Scenario 3a: For all other bands, the number of affected antenna ports can be the same, as shown in Figure 10.

[0139] Scenario 3b: For all other bands, the number of affected antenna ports may be different.

[0140] Figure 11 is a schematic diagram of impact information provided by an embodiment. As shown in Figure 11, txSwitchWithAnotherBand corresponds to information about each of the M bands that require SRS antenna switching with the current band (Switch together UL bands 1, 2, ...M), as well as information about the affected antennas in the bands that require SRS antenna switching with the current band.

[0141] The coding example corresponding to Figure 11 is as follows:

[0142] Among them, txTogetherBand indicates the other bands that will affect the current band when SRS antenna switching is performed; switchTogetherAntennaPorts indicates the number of uplink transmit antenna ports affected when the current band is affected by the SRS antenna switching of certain bands.

[0143] Scenario 3c: The number of antenna ports used for antenna switching on the Band for SRS antenna switching may be indicated, and different impact information may be indicated for different numbers of antenna ports.

[0144] In addition, the reporting granularity may be reporting for each band in each band combination, or reporting for each band (eg, reporting for an independent band list) without being restricted by the band combination.

[0145] Taking scenario 3b as an example, Figure 12 is a schematic diagram of impact information provided by an embodiment. As shown in Figure 12, impact information can be reported for each band rather than for the band combination through an independent band list.

[0146] For scenario 2:

[0147] For the uplink of a certain band, when the SRS antenna switching affects other bands and some or all Tx antenna ports on other bands need to be switched together, these other bands are indicated, and the number of affected antennas (ports) on these other bands is indicated explicitly or implicitly, for example, the number of affected antennas (ports) or the number of unaffected antenna ports.

[0148] Scenario 4a: The UE can specify other bands that need to be switched together with the current band during SRS antenna switching, and specify the number of antenna ports for these other bands to be switched together. The number of antenna ports to be switched together can be the same for all other bands. See Figure 10 for the corresponding impact information.

[0149] Scenario 4b: The number of antenna ports that need to be switched together for all other bands can be different. See Figure 11 for the corresponding impact information.

[0150] Scenario 4c: The UE may indicate the number of antenna ports used for antenna switching on the current band, and indicate different impact information for different numbers of antenna ports.

[0151] The corresponding coding examples are as follows:

[0152] Among them, txTogetherBand indicates other bands affected by the SRS antenna switching of the current band; switchTogetherAntennaPorts indicates the impact of the transmitting antennas on other bands affected by the SRS antenna switching of the current band.

[0153] In addition, the reporting granularity can be for each band in each band combination, or for each band (for example, reporting for an independent band list) without being restricted by the band combination. For the corresponding impact information, please refer to Figure 12.

[0154] Combining the above solutions 1 and 2, a complex scenario arises where the number of antenna ports used for SRS antenna switching varies across different affected bands or band groups, and the number of affected antenna ports on the affected bands also varies. Table 3 shows the relationship between the number of antenna ports for SRS antenna switching (Tx Switching) and the number of antenna ports on the affected bands (Tx Affected).

[0155] Table 3 Relationship between the number of antenna ports for performing SRS antenna switching and the number of antenna ports on the affected band

[0156] Figure 13 is a schematic diagram of impact information provided by an embodiment. As shown in Figure 13, txSwitchWithAnotherBand corresponds to information about the affected antennas corresponding to the different numbers of antenna ports for performing SRS antenna switching in each of the M bands (Switch together UL bands 1, 2, ...M) that need to perform SRS antenna switching with the current band.

[0157] The corresponding coding example of Figure 13 is as follows:

[0158] Among them, txTogetherBand indicates the other bands affected by the SRS antenna switching of the current band; switchTogetherAntennaPorts indicates the impact of the transmit antennas on other bands when the current band performs SRS antenna switching; srsTxPorts indicates the number of transmit antenna ports used when the current band performs SRS antenna switching.

[0159] Alternatively, txTogetherBand indicates the other bands that will be affected by SRS antenna switching on the current band; switchTogetherAntennaPorts indicates the number of uplink transmit antenna ports affected when the current band is affected by SRS antenna switching on certain bands; srsTxPorts indicates the number of transmit antenna ports used when SRS antenna switching on other bands will affect the current band.
