Description

SRS (sounding reference Signal) round-robin configuration information reporting, configuration, terminal and network equipment

Technical Field

The invention relates to the technical field of communication, in particular to reporting, configuring, terminal and network side equipment of SRS (sounding reference signal) round trip configuration information.

Background

In NR (New Radio), the network may configure some SRS (Sounding Reference Signal, channel sounding reference signal) resources for the terminal to transmit SRS on each antenna. In order to ensure the reasonability of SRS resource allocation, the network needs the ability of the terminal to report SRS round trip.

When the terminal reports the capability, a group of capability is required to be reported by each frequency band combination, and the group of capability comprises SRS round-robin capability which can be respectively supported by each frequency band when the terminal works under the frequency band combination. That is, once the SRS round trip capability is reported, the SRS round trip capability is stored at the network end, and the network may perform SRS round trip configuration according to the reported capability. This capability does not support dynamic modification. Each capability option for reporting identifies a static correspondence between the transmit antenna port and the receive antenna.

The reporting of auxiliary information of some terminals is defined in the NR, and the terminal may trigger the reporting when a condition is satisfied, report the current state of the terminal, and the desired configuration to the network. Terminal assistance information cannot directly determine the scheduling policy of the network. The current terminal assistance information includes a configuration of a DRX (Discontinuous Reception ) cycle, a configuration of a number of MIMO (Multiple-Input Multiple-Output), a number of scells (Secondary cells), and the like.

The adjustment of the number of MIMO layers is currently discussed in NR. On partial BWP (Bandwidth part), the number of MIMO layers may be relatively small; the number of MIMO layers may have different configurations on different BWPs.

According to the MIMO technology principle, the number of receiving antennas must be greater than or equal to the maximum number of MIMO layers. If the maximum number of layers is reduced, the terminal may turn off part of the antennas based on the implementation algorithm. In addition, the MIMO layer number includes not only the downlink MIMO layer number but also the uplink MIMO layer number. For example, when the maximum layer number of the uplink MIMO of the network is 2, at least 2 uplink transmission paths are required for the terminal to reserve, and when the maximum layer number of the uplink MIMO of the network configuration is 1, the terminal can close one of the uplink transmission paths to achieve the purpose of energy saving.

In summary, in the current NR, only the adjustment of the maximum MIMO layer number is discussed. When the number of layers is adjusted, the terminal is allowed to turn off part of the receive antennas and/or transmit paths to reduce power consumption. At this time, according to the SRS round trip definition, the SRS round trip configuration of the terminal may also be adjusted accordingly. No specification is currently defined as to how to adjust SRS round robin configuration.

Embodiments of the present invention are described below with reference to the accompanying drawings. The report, the configuration, the terminal and the network side equipment of the SRS round trip configuration information provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, or an evolved long term evolution (Evolved Long Term Evolution, lte) system, or a subsequent evolved communication system. Referring to fig. 1, a schematic architecture diagram of a wireless communication system according to an embodiment of the present invention is provided. As shown in fig. 1, the wireless communication system may include: the network-side device 10 and a terminal (the terminal may also be referred to as a user-side device), for example, the terminal is denoted as UE11, and the UE11 may be connected to the network-side device 10.

It should be noted that the communication system may include a plurality of UEs, and the network-side device may communicate (transmit signaling or transmit data) with the plurality of UEs.

The terminal provided by the embodiment of the invention can be a mobile phone, a tablet personal computer, a notebook computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a Wearable Device, a vehicle-mounted Device or a personal digital assistant (Personal Digital Assistant, PDA) and the like. It should be noted that, in the embodiment of the present invention, the specific type of the terminal is not limited. In the embodiment of the invention, the LTE and NR systems are taken as an example, but the embodiment of the invention is not limited to the system, and the technical scheme provided by the invention can be applied to other systems with the same problems.

As shown in fig. 2, an embodiment of the present invention provides a method for reporting sounding reference signal SRS sounding configuration information supported by a terminal, which is applied to the terminal, and includes:

Step 201, reporting target SRS round trip configuration information corresponding to at least two values of target parameters to a network side device, where the target parameters include: the number of antenna ports supported by the terminal and/or the maximum number of MIMO layers supported by the terminal.

For example, the reported target SRS round trip configuration information includes:

SRS round trip configuration information for maximum MIMO layer number 4;

and (5) transmitting configuration information for SRS with the maximum MIMO layer number of 2.

In the embodiment of the present invention, the "target SRS round trip configuration information corresponding to at least two values of the target parameter" may be the same or different, but the target SRS round trip configuration information is different. For example, if the target parameter is the maximum MIMO layer number, the terminal reports a target SRS round trip configuration information of 1T4R for the first target parameter value, i.e. 4, and the terminal reports a target SRS round trip configuration information of 1T2R for the second target parameter value, i.e. 4. At this time, the first target parameter value is the same as the second target parameter value. For another example, if the target parameter is the maximum MIMO layer number, the terminal reports a target SRS round trip configuration information of 1T4R for the first target parameter value, i.e. 4, and the terminal reports a target SRS round trip configuration information of 1T2R for the second target parameter value, i.e. 2. At this time, the first target parameter value and the second target parameter value are different.

Wherein the number of T identifies the number of uplink transmitting antenna ports of the current terminal, and the number of R is the number of antennas in the whole set or a subset of receiving antennas of the terminal.

In the step, a terminal reports a group of 'target SRS round trip configuration information corresponding to at least two values of target parameters' for a frequency band; in other words, "the target SRS round trip configuration information corresponding to at least two values of the target parameter" specifically means: and when the terminal works in the frequency band, the supported SRS transmits configuration information. Optionally, the terminal may report the target SRS round trip configuration information for one frequency band in a specific reporting process, or may report the SRS round trip configuration information for one frequency band combination (in this case, the reported SRS round trip configuration information includes the target SRS round trip configuration information corresponding to each frequency band in the frequency band combination), which is not specifically limited herein.

Optionally, the number of antenna ports includes: the number of transmit antenna ports and/or the number of receive antenna ports.

Optionally, the maximum MIMO layer number includes: the maximum number of uplink MIMO layers and/or the maximum number of downlink MIMO layers.

As an alternative embodiment, step 201 includes:

And reporting first antenna round trip capability information to the network side equipment, wherein the first antenna round trip capability information comprises target SRS round trip configuration information corresponding to at least two values of target parameters. And the terminal reports the target SRS round trip configuration information to the network side equipment when reporting the antenna round trip capability.

In this way, after the terminal reports the first antenna round trip capability information, the network side device stores the first antenna round trip capability information, and the network side device can perform SRS round trip configuration according to the target parameter currently used by the terminal and the first antenna round trip capability information, where the method further includes:

receiving SRS resources configured by the network side equipment for antenna round trip of the terminal; the SRS resource is related to the first antenna round-robin capability information reported by the terminal and the target parameter currently used by the terminal;

and performing SRS round trip according to the SRS resources.

Generally, after the network side device configures the SRS resource for the terminal for the first time according to the target parameter currently used by the terminal and the first antenna round trip capability information, the network side device may be triggered to reconfigure the SRS resource for the terminal when the target parameter used by the terminal changes.

For example, the target SRS round trip configuration information reported by the terminal includes: SRS burst configuration information a for a maximum MIMO layer number of 4 and SRS burst configuration information B for a maximum MIMO layer number of 2. At the first moment, if the maximum MIMO layer number of the terminal is 4, the network side equipment configures SRS resources for the terminal according to the SRS round trip configuration information A; in the case that the maximum MIMO layer number of the terminal is modified to 2, the network side device needs to reconfigure SRS resources for the terminal according to SRS round trip configuration information B.

Further, in the case that at least two values of the target parameter are the same, the method further includes:

and reporting auxiliary information to network side equipment, wherein the auxiliary information comprises indication information, the indication information is used for indicating first SRS round trip configuration information which is activated currently, and the first SRS round trip configuration information is one of at least two SRS round trip configuration information corresponding to the same value of the target parameter.

For example, if the target parameter is the maximum MIMO layer number, the terminal reports a target SRS round trip configuration information of 1T4R for the first target parameter value, i.e. 4, and the terminal reports a target SRS round trip configuration information of 1T2R for the second target parameter value, i.e. 4. At this time, the first target parameter value is the same as the second target parameter value. Further, the terminal needs to indicate the currently activated SRS round trip configuration information through the auxiliary information, if the auxiliary information indicates 1T4R, the terminal indicates that the currently activated SRS round trip configuration information is 1T4R, and for the case that the maximum MIMO layer number is 4, the network side device configures SRS resources for the terminal according to 1T 4R.

Optionally, in order to reduce signaling overhead for reporting SRS round trip configuration information, the reporting the first antenna round trip capability information to the network side device includes:

Determining default SRS round-trip configuration information corresponding to the target parameters according to rules defined by the protocol;

and reporting the first antenna round trip capability information to the network side equipment under the condition that the default SRS round trip configuration information is different from the target SRS round trip configuration information.

In order to reduce signaling overhead of reporting the SRS round trip configuration information, the protocol defines a rule for determining default SRS round trip configuration information based on the target parameter, for example, default SRS round trip configuration information tables corresponding to different values of the target parameter; for example, the protocol defines that for 4 cases { max_dl_mimo_layer=4, max_ul_mimo_layer=2 }, { max_dl_mimo_layer=2, max_ul_mimo_layer=2 }, { max_dl_mimo_layer=4, max_ul_mimo_layer=1 }, { max_dl_mimo_layer=2, max_ul_mimo_layer=1 } the default SRS round configuration information of the terminal is 1T4R-2t4R,2t2R,1t4R,1t2R, respectively. If the terminal finds that the target SRS round trip configuration information is not matched with the default SRS round trip configuration information, reporting the target SRS round trip configuration information is needed; otherwise, the terminal and the network side equipment can determine the same SRS round trip configuration information aiming at the target parameter according to the protocol definition without reporting the target SRS round trip configuration information.

As shown in fig. 3, in an example one, the terminal indicates the target SRS round trip configuration information according to the report of the first antenna round trip capability information, specifically including:

step 301, a terminal reports target SRS round trip configuration information in an antenna round trip capability reporting stage for different maximum MIMO layer numbers;

in this step, when the terminal reports the antenna round trip capability, for each frequency band combination, SRS round trip configuration information corresponding to different maximum MIMO layer numbers is reported on each frequency band. For example, the terminal may report SRS round trip configuration information of max_dl_mimo_layer=4 (downlink maximum MIMO layer number=4) and max_dl_mimo_layer=2 (downlink maximum MIMO layer number=2), respectively. max_dl_mimo_layer is an option for the maximum number of downlink MIMO layers indicated by the network. Further, assuming that max_ul_mimo_layer (the maximum number of uplink MIMO layers) is further considered, the terminal may further report SRS burst configuration information corresponding to the total of 4 states of { max_dl_mimo_layer=4, max_ul_mimo_layer=2 }, { max_dl_mimo_layer=2, max_ul_mimo_layer=2 }, { max_dl_mimo_layer=4, max_ul_mimo_layer=1 }, { max_dl_mimo_layer=2, and max_ul_mimo_layer=1 }, respectively.

Specifically, the antenna round-robin capability reporting may be performed by the terminal after determining the default capability based on a rule defined by a protocol. The rule may be a default capability table with different maximum MIMO layer numbers. For example, the protocol defines that for 4 cases { max_dl_mimo_layer=4, max_ul_mimo_layer=2 }, { max_dl_mimo_layer=2, max_ul_mimo_layer=2 }, { max_dl_mimo_layer=4, max_ul_mimo_layer=1 }, { max_dl_mimo_layer=2, max_ul_mimo_layer=1 } the default terminal capabilities are 1T4R-2T4R,2T2R,1T4R,1T2R, respectively. When the UE discovers that the current self-capacity is not matched with the default capacity, the UE needs to report the corresponding capacity, if the terminal capacity is consistent with the table defined by the protocol under a certain configuration, the terminal does not need to report the capacity, and the network default terminal has the capacity defined by the corresponding table.

Fig. 4 shows a terminal antenna switching architecture corresponding to SRS round robin for 2T 4R; for example, if the terminal tends to turn off Ant1 and Ant3, the terminal may report SRS carousel configuration information of 2t=2r for the maximum MIMO layer number of 2; for another example, the terminal tends to turn off Ant2 and Ant3, and the terminal may report SRS carousel configuration information of 1T2R for a maximum MIMO layer number of 2.

For terminals supporting 1T2R-2T4R on all or part of the bands on a certain band group, a terminal antenna switching architecture corresponding to SRS round robin for 1T2R-2T4R is shown in fig. 5; the terminal may report SRS sounding configuration information of 1T2R or SRS sounding configuration information of 2t=2r for the maximum MIMO layer number of 2.

For terminals supporting 1T4R on all or part of the bands on a certain band group, a terminal antenna switching architecture corresponding to SRS round trip transmission of 1T4R is shown in fig. 6; the terminal may report SRS sounding configuration information of 1T2R for the maximum MIMO layer number of 2.

For terminals supporting 1T2R on all or part of the bands on a certain band group, a terminal antenna switching architecture corresponding to SRS round robin of 1T2R is shown in fig. 7; in this case, the maximum MIMO layer number may be up to 4 layers. At this time, for the maximum MIMO layer number of 2, the terminal may report SRS sounding configuration information of 1t=1r, or SRS sounding configuration information of 1t2R, or directly report the SRS sounding configuration information that is not supported.

In summary, the terminal may configure according to the reporting capability of the terminal when the network limits the maximum MIMO layer number to 2 according to the reporting capability of the scene corresponding to the maximum MIMO layer number to 2. The number of receiving antennas in the reporting capability of the terminal may not correspond to the maximum number of layers. The number of the receiving antennas may be greater than the maximum number of layers, may be equal to the maximum number of layers, or may be less than the maximum number of layers.

Step 302, the network side equipment configures SRS resources according to the antenna round-robin capability reported by the terminal and the current maximum MIMO layer number.

For example, for a terminal supporting 2T4R on all or part of the bands on a certain band combination, as shown in fig. 4, when the maximum MIMO layer number configured by the network on at least 1 band in the band combination is 4, the terminal must turn on all of Ant0 to Ant3, and in this case, on some other bands, even if the maximum MIMO layer number is limited by the network to be 2, the terminal may transmit SRS on 4 antennas, so as to ensure the receiving performance of 2 antennas, and may also turn off a part of radio frequency channels and transmit SRS on part of the bands. However, if the maximum MIMO layer number of all the bands in the band combination is 2 and the terminal has a strong energy saving requirement, the terminal may turn off a part of the antennas. At this time, the network may configure SRS resources for the terminal according to SRS round trip configuration information corresponding to the maximum MIMO layer number of 2.

Optionally, the network may configure SRS resources of SRS round robin of the terminal based on the limited maximum configuration layer number under the current carrier, or may configure SRS resources according to the limited maximum MIMO layer number after all carriers limit the maximum MIMO layer number in carrier aggregation CA or dual connectivity DC.

In step 303, the terminal performs SRS round robin according to the network configuration.

Further, as an optional implementation option, the terminal reports different SRS round trip capability for two identical MIMO layers, and further, the terminal may instruct the network activated SRS round trip configuration information through the auxiliary information at a specific time. And the terminal reports the auxiliary information and informs the SRS round trip configuration information activated currently by the network. Specifically, the configuration reported by the auxiliary information is one of a plurality of pieces of SRS round trip configuration information reported by the round trip capability of the terminal antenna. The network side equipment further performs resource allocation of SRS round trip according to the auxiliary information of the terminal.

For example, as shown in fig. 4, the terminal may report two capabilities, 1T2R and 2T2R, for a scenario with a maximum MIMO layer number of 2. Specifically, after the number of the maximum MIMO layers is reduced to 2, the terminal may further report auxiliary information to notify the network that the current SRS round trip configuration needs to be modified to 1T2R, for example, the terminal needs to turn off Ant2 and Ant3. At this time, the network may further configure according to the auxiliary information reported by the terminal. In this case, the terminal may flexibly perform antenna closing according to the actual situation, for example, a holding gesture, etc.

As another alternative embodiment, step 201 includes:

reporting second antenna round trip capability information to the network side equipment, wherein the second antenna round trip capability information comprises first SRS round trip configuration information corresponding to a first value of a target parameter;

reporting auxiliary information to the network side equipment, wherein the auxiliary information comprises second SRS round trip configuration information corresponding to at least one second value of the target parameter;

the target SRS round trip configuration information comprises first SRS round trip configuration information and at least one second SRS round trip configuration information.

In particular, the first value and the second value of the target parameter may be the same or different. For example, if the target parameter is the maximum MIMO layer number, the UE reports 1T4R for the value of the first target parameter, i.e. 4, in the capability report; and the UE reports 1T2R in the auxiliary information reporting aiming at the second target parameter value, namely 4. At this time, the first target parameter value is the same as the second target parameter value. For another example, if the target parameter is the maximum MIMO layer number, the UE reports 1T4R for the first target parameter, i.e. 4, in the capability report, and reports 1T2R for the second target parameter, i.e. 2, in the auxiliary information report. At this time, the first target parameter value is the same as the second target parameter value. At this time, the first target parameter value and the second target parameter value are different.

In this way, the terminal reports the basic SRS capability (i.e., the first SRS round trip configuration information) to the network side device, and reports the adjusted SRS round trip configuration information (i.e., at least one second SRS round trip configuration information) through the auxiliary information, so that the network side device can perform SRS round trip configuration according to the auxiliary information. Correspondingly, the method further comprises the steps of:

receiving SRS resources configured by the network side equipment for antenna round trip of the terminal; the SRS resource is related to second antenna round transmission capability information and/or auxiliary information reported by the terminal;

and performing SRS round trip according to the SRS resources.

After receiving the auxiliary information, the network side device may configure SRS resources for the terminal according to the auxiliary information, or may not perform SRS configuration according to the auxiliary information.

Optionally, the number of receiving antennas in the second SRS carousel configuration information is smaller than or equal to the number of receiving antennas in the first SRS carousel configuration information.

If the SRS resource configured by the network side device is not based on the newly reported auxiliary information, performing SRS round trip according to the SRS resource includes:

transmitting SRS signals from the same receiving antenna or the same receiving antenna port on the SRS resource; or, transmitting the corresponding SRS signal on a part of SRS resources, and setting the power of other SRS resources except the SRS resources for transmitting the SRS signal to zero.

In other words, after the terminal adjusts the maximum MIMO layer number (for example, when adjusting from 1T4R to 1T 2R), the SRS carousel configuration information is not adjusted accordingly, in which case, the terminal may implement dynamic adjustment of SRS transmission by using a manner of repeating antenna transmission or non-transmission.

As shown in fig. 8, in example two, the terminal informs, through auxiliary information, SRS carousel configuration information currently supported by the network terminal, specifically including:

step 801, a terminal reports basic SRS capability; for example, only SRS carousel configuration information for one maximum MIMO layer number is reported.

Step 802, configuring SRS resources by the network side equipment according to basic SRS capability;

step 803, the terminal performs SRS round trip transmission according to the network side configuration;

step 804, the terminal reports auxiliary information and modifies the SRS round trip configuration information currently supported; optionally, in the reporting of the auxiliary information of the terminal, the number of receiving antennas is not higher than the number of receiving antennas corresponding to the basic SRS capability. For example, for the scenario of fig. 4, where the terminal reporting capability is 2T4R, for the scenario of 2 maximum MIMO layers, the number of receiving antennas in the auxiliary information reported by the terminal can only be 2 of 1T2R, or 4 of 2T 4R.

Step 805, the network modifies SRS round trip configuration according to the auxiliary information of the terminal; then step 803 is returned.

Optionally, after the terminal auxiliary information is reported, the network may still not perform SRS round-robin configuration according to the terminal auxiliary information, and at this time, the terminal may achieve the purpose of closing part of the antenna ports by repeating the transmission on the same antenna or not transmitting on the corresponding antenna. For example, for the scenario of fig. 4, in the scenario where the maximum number of layers is 2, the network configures SRS sounding of 2T4R, but the terminal only turns on two antennas corresponding to the first group 1T2R, e.g., ant0 and Ant1, and two antennas corresponding to the second group 1T2R, e.g., ant2 and Ant3, are in an off state. At this time, the terminal may transmit on the SRS resource corresponding to the first set 1T2R, but not transmit on the SRS resource corresponding to the second set 1T2R, i.e. the power is set to the power of the OFF state. In addition, on the SRS resource corresponding to the second group 1T2R, the corresponding SRS signals may be transmitted by using the turned-on antennas, that is, ant0 and Ant 1.

In summary, the above embodiment of the present invention can achieve the purpose of adjusting SRS round trip configuration information correspondingly under the condition that the value of the target parameter is adjusted by reporting SRS round trip configuration information corresponding to at least two values of the target parameter to the network side device; further, the network side equipment performs antenna round trip configuration according to SRS round trip configuration information corresponding to the value of the current target parameter, SRS resource overhead is reduced, and efficiency is improved; meanwhile, the terminal can perform SRS round trip based on the better SRS round trip allocation information, and the downlink transmission income is improved.

As shown in fig. 9, an embodiment of the present invention further provides a configuration method of channel sounding reference signal SRS round trip, which is applied to a network side device, and includes:

step 901, obtaining target SRS round trip configuration information corresponding to at least two values of target parameters, where the target parameters include: the number of antenna ports supported by the terminal and/or the maximum MIMO layer supported by the terminal;

step 902, configuring SRS resources for antenna round trip of the terminal according to the target SRS round trip configuration information.

For example, the target SRS round trip configuration information includes:

SRS round trip configuration information for maximum MIMO layer number 4;

In the embodiment of the present invention, the "target SRS round trip configuration information corresponding to at least two values of the target parameter" may be the same or different, but the target SRS round trip configuration information is different. For example, if the target parameter is the maximum MIMO layer number, the terminal reports a target SRS round trip configuration information of 1T4R for the first target parameter value, i.e. 4, and the terminal reports a target SRS round trip configuration information of 1T2R for the second target parameter value, i.e. 4. At this time, the first target parameter value is the same as the second target parameter value.
