Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to a communication method, an apparatus, and a computer-readable storage medium. Background Art

[0002] In a system of the fifth-generation mobile communications (5G for short), according to existing protocols, the functional uses of the sounding reference signal (SRS for short) mainly include four categories: uplink beam management, obtaining uplink channel information for the uplink transmission scheme based on a codebook (codebook), obtaining uplink channel information for the non-codebook uplink transmission scheme (non-codebook), and obtaining downlink channel information based on SRS antenna switching (antenna switching).

[0003] Future protocols may use SRS for the sensing function. Therefore, it is necessary to solve how to configure SRS so that it can perform the sensing function, and what possible associated protocol changes are also required to achieve this function, so that the terminal and the network side can reliably implement the sensing function based on SRS.

[0043] Compared with the prior art, the technical solution of the embodiment of the present application has the following beneficial effects:

[0044] An embodiment of the present application provides a communication method, including: receiving first information, where the first information includes a trigger signaling for triggering the transmission of a first channel sounding reference signal, the first channel sounding reference signal is a channel sounding reference signal for sensing, and the first channel sounding reference signal is associated with a first physical uplink control channel; sending the first channel sounding reference signal, and reporting a sensing result using the first physical uplink control channel.

Specifically, a binding indication relationship is established between the SRS for sensing (i.e., the first SRS) and the PUCCH (e.g., the first PUCCH), enabling the terminal to report the uplink channel sensing result to the network device, ensuring that both parties can reliably implement the sensing function.

[0046] Furthermore, the SRS resource for sensing is configured through second information to ensure that the terminal can use the first SRS to perform the sensing function.

[0047] Furthermore, the length / granularity / repetition transmission of the resources in the first resource set is different from that of the resources in the second resource set, which is beneficial to improving the sensing accuracy and ensuring the reliable implementation of the sensing function.

[0051] To make the above objects, features, and beneficial effects of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application is provided in conjunction with the drawings.

[0052] Figure 1It is a flowchart of a communication method according to an embodiment of the present application.

[0053] This implementation solution can be applied to a 5G system, for example, to an application scenario where SRS is configured for sensing in a 5G system. In the sensing scenario, the terminal can send SRS and receive the echo signal of the SRS, and then perform sensing algorithm processing on the echo signal. For the processed sensing result, it can be reported to the base station or the sensing function (SF) through the uplink channel. The sensing function can be a network element of the core network. Or, it can also be that the terminal sends SRS for sensing (denoted as the first SRS), and the base station (for example, gNB) receives the echo signal. Or, it can also be that terminal A sends the first SRS and terminal B receives the echo signal. The sensing result can be used by the terminal that sends the first SRS, or by the base station, or by the SF, or by other terminals.

[0054] In a specific implementation, in the communication method provided in the following steps S101 to S102, the steps implemented by the terminal can be executed by a chip with communication functions in the terminal, or can be executed by the baseband chip in the terminal; the steps implemented by the network device can be executed by a chip with communication functions in the network device, or can be executed by the baseband chip in the network device.

[0055] Specifically, referring to Figure 1 , the communication method described in this implementation solution may include the following steps:

[0056] Step S101, the network device sends the first information to the terminal, and the first information includes a trigger signaling, and the trigger signaling is used to trigger the sending of the first SRS, and the first SRS is the SRS for sensing, and the first SRS is associated with the first Physical Uplink Control Channel (abbreviated as PUCCH). Correspondingly, the terminal receives the first information.

[0057] Step S102, the terminal sends the first SRS and reports the sensing result using the first PUCCH. Correspondingly, the network device receives the sensing result using the first PUCCH.

[0058] In some embodiments, the first SRS according to the time domain characteristic (also referred to as the time domain type) may include one of the following: periodicity (abbreviated as P) SRS (also referred to as statically scheduled SRS), semi-persistent (abbreviated as SP) SRS (also referred to as semi-statically scheduled SRS), and aperiodicity (abbreviated as A) SRS.

[0059] All parameters of the configured periodic SRS resource are configured by higher layer signaling (e.g., Radio Resource Control (RRC) signaling), and the terminal performs periodic transmission according to the configured parameters.

[0060] The configured semi-persistent SRS resource is also periodically transmitted during activation. The difference between it and the periodic SRS is that the terminal does not send SRS after receiving the higher layer signaling configuration of the semi-persistent SRS resource, and only starts to periodically transmit the first SRS corresponding to the semi-persistent SRS resource after receiving the activation signaling of the semi-persistent SRS resource sent by the Medium Access Control (MAC) layer. The transmission of the first SRS stops after receiving the deactivation command of the semi-persistent SRS resource sent by the MAC layer.

[0061] The configured aperiodic SRS resource is activated by Downlink Control Information (DCI). Each time the terminal receives an SRS trigger signaling that triggers the aperiodic SRS resource, it performs a transmission of the first SRS corresponding to the triggered SRS resource. In this example, the first information in step S101 may include the trigger signaling, which is carried by DCI. Further, the terminal may also receive RRC signaling to obtain the configuration information of the first SRS (specifically, refer to the relevant description of the second information below).

[0062] Next, taking the aperiodic SRS as an example, the configuration and uplink reporting of the first SRS in this application are elaborated in detail.

[0063] In step S102, for the mode of the terminal's self-transmission and self-reception, after the first SRS is transmitted, its echo is received, and then the sensing algorithm analysis is performed, and the sensing result is reported to the base station or other terminals. In this scenario, the sensing result needs to be shared with the base station or other terminals, and the content sensed by different devices may be different.

[0064] In a specific implementation, a binding indication relationship can be established between the first SRS and the first PUCCH, so that the terminal can use the first PUCCH to transmit the sensing result. For example, when the DCI triggers the first SRS, the first PUCCH resource can be configured at the same time for the feedback of the sensing result.

[0065] Specifically, the first information may include a first indication field for indicating the first PUCCH.

[0066] Further, the DCI that can carry the first information may include DCI of format 0_1, format 0_2, format 1_1, format 1_2, and 2_3.

[0067] In some embodiments, for the DCI used to schedule uplink transmissions (i.e., the DCI of format 0_1 and format 0_2), there is originally no PUCCH resource indicator (PRI) indication field in such DCI. Therefore, in this implementation, a new indication field is added to such DCI to carry the PUCCH report of the sensing result for the first SRS.

[0068] For example, a new format of DCI can be designed for scheduling uplink transmissions, and the new format of DCI includes a PRI indication field, and the PRI indication field is used to indicate the resource of the first PUCCH.

[0069] In some embodiments, for the DCI used to schedule downlink transmissions (i.e., the DCI of format 1_1 and format 1_2), the first indication field can reuse the original PRI indication field in such DCI.

[0070] Specifically, the first indication field can be used to indicate the first PUCCH and to indicate the second PUCCH, and the second PUCCH is used to carry the feedback result of the Physical Downlink Shared Channel (PDSCH for short).

[0071] That is to say, the first indication field simultaneously indicates two PUCCH resources, namely the resource of the first PUCCH and the resource of the second PUCCH. Correspondingly, the PDSCH Hybrid Automatic Repeat reQuest (HARQ) acknowledgement (ACK) and the sensing result are reported separately on different PUCCHs.

[0072] For example, the first indication field can be increased from the existing fewer bits (e.g., 3 bits) to 6 bits, where the higher 3 bits are used to indicate the second PUCCH and the lower 3 bits are used to indicate the first PUCCH.

[0073] For another example, in the 6-bit first indication field, the higher 3 bits can correspond to the PUCCH resource indication carrying the sensing result, and the lower 3 bits can correspond to the PUCCH resource indication carrying the PDSCH HARQ-ACK.

[0074] In some embodiments, for the DCI used to schedule downlink transmissions (i.e., the DCI of format 1_1 and format 1_2), the original PRI indication field in such DCI can be reused to indicate the first PUCCH.

[0075] Specifically, the first information may include a first indication field and a second indication field. Among them, the first indication field is used to indicate the first PUCCH, and the second indication field is used to indicate the second PUCCH. The first indication field and the second indication field may be two independent PRI fields.

[0076] That is to say, two PRI indication fields are used to respectively indicate two PUCCHs, so as to realize the separate reporting of PDSCH HARQ-ACK and sensing results on different PUCCHs.

[0077] For example, the PRI indication field in the first information can be increased to 6 bits. These 6 bits are divided into two independent fields. Among them, the 3-bit field is used as the first indication field to indicate the first PUCCH, and the remaining 3-bit field is used as the second indication field to indicate the second PUCCH.

[0078] In some embodiments, for the DCI used to schedule downlink transmission (that is, the DCI of format 1_1 and format 1_2), the PUCCH indicated by the PRI indication field in such DCI can be directly multiplexed to transmit the sensing result and the PDSCH feedback result together.

[0079] Specifically, the first PUCCH can be used to carry the sensing result and the feedback result of the PDSCH. That is to say, the PDSCH HARQ-ACK and the sensing result are reported on the same PUCCH. Optionally, the sorting of the PDSCH HARQ-ACK and the sensing result in the uplink control information (UCI: Uplink Control Information) can be that the PDSCH HARQ-ACK is in the front and the sensing result is in the back, or the sensing result is in the front and the PDSCH HARQ-ACK is in the back.

[0080] In this example, the sensing result can be regarded as a new CSI content, such as a new channel state information reference signal (Channel State Information-Reference Signal, abbreviated as CSI-RS).

[0081] As described above, the implementation of separately reporting the PDSCH HARQ-ACK and the sensing result on two PUCCHs can preferably be applied to scenarios where the processing timeline does not allow. Specifically, considering the processing capacity of the terminal, from the transmission of the first SRS to the reception of the echo, and then to the completion time of processing into sensing information and packing to obtain the sensing result, if the completion time and the completion time of processing the PDSCH feedback result are far apart, it is considered a scenario where the processing timeline does not allow. At this time, it is preferably to separately report the sensing result and the PDSCH feedback result on two PUCCHs, which is beneficial to reducing the delay.

[0082] If the processing capacity of the terminal enables the time for generating the sensing result and the time for generating the PDSCH feedback result to be relatively close, that is, before the PUCCH resource indicated by the PRI indication field arrives, the terminal can both complete the processing of the PDSCH HARQ-ACK and complete the processing of the sensing result, it is considered to belong to the scenario allowed by the processing schedule. At this time, preferably, the sensing result and the PDSCH feedback result are reported on a single PUCCH, which is beneficial to saving signaling overhead and reducing communication load.

[0083] In a specific implementation, the association relationship between the first SRS and the first PUCCH can be configured by high-layer signaling. For example, the non-periodic SRS for sensing can be directly associated with a PUCCH through RRC signaling. Specifically, it can be that 1 SRS resource set is associated with 1 PUCCH resource, or 1 or more SRS resources are associated with 1 PUCCH resource.

[0084] In a specific implementation, before step S101, this implementation solution may further include the step: the network device sends second information to the terminal, and the second information includes multiple candidate first resource sets, and the resources in the first resource set are used to transmit the first SRS. Correspondingly, the terminal receives the second information.

[0085] Specifically, the network can pre-configure multiple candidate first resource sets for the terminal through the second information, and then activate or trigger one of them through the first information for the terminal to send the first SRS.

[0086] In some embodiments, the time-domain granularity of the first SRS for sensing can be longer than that of the second SRS for traditional other uses, which can specifically depend on the accuracy requirements of velocity or angle.

[0087] For example, the length of the resources in at least one of the first resource sets can be greater than the length of a single time slot, such as greater than 14 OFDM symbols. The longer the number of symbols of the resources of the first SRS for sensing, the higher the sensing accuracy, and correspondingly, the resources in the first resource set can be allowed to be configured across multiple time slots.

[0088] For another example, the resources in at least one of the first resource sets are configured in units of symbols. For example, the resources can be configured to start from the first symbol of the first time slot and end at the fifth symbol of the second time slot.

[0089] For yet another example, multiple time-domain granularities can be mixed and configured, such as a resource can include x time slots and y symbols.

[0090] In an embodiment, the resources in at least one first resource set can be transmitted periodically and repeatedly.

[0091] Specifically, a repetition factor may be added to the second information to indicate the number of times of repeated transmission of resources in the first resource set.

[0092] For example, the length of the resources in the first resource set may be configured to be 6 OFDM symbols and transmitted for 4 cycles.

[0093] In some embodiments, the first resource set may be configured to be dedicated to the first SRS. For example, similar to the SRS for positioning purposes, the configuration of the independent SRS for sensing may be given in the second information.

[0094] In some embodiments, the first resource set may be a resource set configured for sensing purposes. For example, a new type (i.e., sensing type) may be added to the uses of the existing SRS resource set. Thus, the SRS resource set in the RRC signaling may be configured as the first resource set for sensing or as the second resource set for other uses. The second resource set is used to send the second SRS.

[0095] In some embodiments, the second information may be carried by high-layer signaling, for example, carried by RRC signaling.

[0096] In a specific implementation, SRS may be classified into two major categories according to its use (also known as function): the first SRS for sensing and the second SRS for other uses. Among them, other uses may include uplink beam management, uplink channel information acquisition based on the codebook uplink transmission scheme (codebook), uplink channel information acquisition based on the non-codebook uplink transmission scheme (non-codebook), and downlink channel information acquisition based on SRS antenna switching (antennaswitching).

[0097] Furthermore, the number of existing SRS resource sets may be increased, so as to configure a dedicated first resource set for the first SRS. For example, the network side may pre-configure multiple candidate SRS resource sets, including at least one candidate first resource set and multiple candidate second resource sets. Among them, the resources in the first resource set are used to send the first SRS, and the resources in the second resource set are used to send the second SRS.

[0098] In a specific implementation, taking the non-periodic SRS as an example, the triggering signaling may correspond to the first resource set. Each time the terminal receives a triggering signaling for triggering the non-periodic SRS resource, it performs a transmission of the first SRS corresponding to the triggered SRS resource (for example, the resources in the first resource set).

[0099] Correspondingly, in step S102, the terminal uses the resources in the first resource set corresponding to the trigger signaling to transmit the first SRS.

[0100] Furthermore, the trigger signaling may include a third indication field for indicating the first resource set.

[0101] In some embodiments, the association manner between the traditional trigger state and the SRS resource set may be maintained. Specifically, the SRS trigger signaling in the traditional DCI usually contains 2 bits, and the SRS resource set associated with the trigger state can be indicated by indicating the trigger state. Optionally, the network side may configure the SRS resource set or the PUCCH resource associated with the SRS resource through higher layer signaling. When the DCI triggers the SRS resource set, the perception information based on the SRS measurement is transmitted on the SRS resource set or the PUCCH resource associated with the SRS resource.

[0102] Furthermore, specifically in this example, in addition to indicating the first resource set, the first indication field may also be used to indicate a second resource set, and the second resource set is used for the transmission of other SRSs (i.e., the second SRS) in addition to the first SRS. Correspondingly, the number of bits of the third indication field in the SRS trigger signaling of the DCI may be increased from 2 bits to, for example, 4 bits. In these 4 bits of the third indication field, the first 2 bits are used to indicate the second resource set, and the last 2 bits are used to indicate the first resource set.

[0103] In some embodiments, the third indication field may be an independent trigger indication field. Correspondingly, the trigger signaling may include a third indication field (a newly added field compared with the SRS trigger signaling in the existing DCI), and a fourth indication field (similar to the state indication in the SRS trigger signaling of the existing DCI), and the fourth indication field is used to indicate the second resource set.

[0104] For example, the trigger signaling in the first information may be increased to 4 bits, and these 4 bits are divided into two independent fields. Among them, the 2-bit field is used as the third indication field to indicate the first resource set, and the remaining 2-bit field is used as the fourth indication field to indicate the second resource set.

[0105] In a specific implementation, the second information may include a first offset value for determining the time interval (slot offset) between receiving the trigger signaling and performing PUCCH transmission.

[0106] Specifically, different from the offset value configured for the second SRS (e.g., configured by RRC signaling), which is the time interval between triggering the second SRS transmission (e.g., triggered by DCI) and the actual second SRS transmission at the terminal, the first offset value in this embodiment is the time interval between the first SRS and the PUCCH.

[0107] For example, the length of the first offset value can be greater than the length of the offset value configured for the second SRS. Thus, the terminal can have sufficient time to receive the echo signal and process the sensing information.

[0108] In some embodiments, the first offset value can be configured by resource. That is to say, the configuration of the first offset value can be achieved on a resource-wise basis. Wherein, the resource can be a time slot or a symbol, or other time-domain resource granularities, which are not limited in the present invention.

[0109] Specifically, compared with the resources in the second resource set that only need to select the one with the best signal for feedback during communication, the resources in the first resource set in this embodiment are used for sensing. Therefore, the resources in the first resource set need to send the first SRS in different directions. Further, there are differences in the echoes fed back in different directions (e.g., different arrival times at the terminal). Therefore, appropriate first offset values can be configured for each resource in the first resource set respectively.

[0110] For example, the first offset value can be associated with the beam direction. Assume that the first resource set includes resource 1, resource 2, and resource 3. The terminal uses resource 1 to send the first SRS in beam direction 1, uses resource 2 to send the first SRS in beam direction 2, and uses resource 3 to also send the first SRS in beam direction 2. Correspondingly, resource 1 can correspond to the first offset value 1, and resources 2 and 3 can correspond to the first offset value 2.

[0111] In a specific implementation, the first information can include a second offset value, where the second offset value can be indicated by a first flexible indication field. Further, the time interval between receiving the trigger signaling and performing the PUCCH transmission can be jointly determined according to the first offset value and the second offset value.

[0112] Similarly, the first information can also include a third offset value configured for the second SRS. The time interval between triggering the second SRS transmission and the actual second SRS transmission can be jointly determined according to the offset value configured for the second SRS by the second information and the third offset value.

[0113] In some embodiments, the second offset value and the third offset value can share the same flexible indication field.

[0114] Specifically, the first dynamic indication field can be used to indicate the second offset value and the third offset value.

[0115] For example, a set of candidate values {2, 4, 6, 8} for the first dynamic indication field can be predefined, pre-configured by the network, or specified by the protocol. The first dynamic indication field in the first information can select {2, 8} from it and indicate it to the terminal. Accordingly, the terminal determines that the third offset value is 2 and the second offset value is 8.

[0116] In some embodiments, the second offset value and the third offset value can each have an independent dynamic indication field.

[0117] Specifically, the first information can further include a second dynamic indication field for indicating the third offset value.

[0118] For example, a set of candidate values {2, 4, 6, 8} for the first dynamic indication field and candidate values {2, 4, 6} for the second dynamic indication field can be predefined, pre-configured by the network, or specified by the protocol. The first dynamic indication field in the first information can select {8} from {2, 4, 6, 8} and indicate it to the terminal, and the second dynamic indication field can select {2} from {2, 4, 6} and indicate it to the terminal. Accordingly, the terminal determines that the third offset value is 2 and the second offset value is 8.

[0119] For another example, the first dynamic indication field in the first information can select {6} from {2, 4, 6, 8} and indicate it to the terminal, and the second dynamic indication field can select {6} from {2, 4, 6} and indicate it to the terminal. Accordingly, the terminal determines that both the third offset value and the second offset value are 6.

[0120] In a variant, the third offset value can be omitted, that is, the second offset value can be used to determine the time interval of the first SRS and also the time interval of the second SRS.

[0121] In a specific implementation, before performing step S101, this implementation can further include the step: the terminal reports capability information to the network device, and the capability information includes the time interval for sensing, and the time interval for sensing is the minimum time interval between receiving the trigger signaling and performing PUCCH transmission. Accordingly, the network device receives the capability information reported by the terminal.

[0122] Further, in response to receiving the capability information, the network device determines the first offset value accordingly. For example, when configuring the network, the first offset value will not exceed the terminal capability, such as configuring the specific value of the first offset value not less than the minimum time interval.

[0123] For example, a parameter k3 can be added to the capability information to indicate the time interval between SRS (for example, the first SRS) and PUCCH transmission.

[0124] In a specific implementation, in step 102, if it is determined to send the first SRS, then further, the first SRS can be sent according to the default beam direction.

[0125] Specifically, when the network does not configure a beam direction for the first SRS, the terminal can send the first SRS according to the default beam direction to successfully perform the sensing function.

[0126] In some embodiments, the default beam direction can be the beam direction of the most recent successful object sensing. For example, in an intrusion detection scenario, the beam direction of the most recent successful object sensing can be used as the default beam direction of the current first SRS. Intrusion detection can be, for example, airspace detection, such as the detection of a drone intruding into a private residence.

[0127] In some embodiments, the default beam direction can be determined according to the configured listening range.

[0128] Specifically, the network can pre-configure a listening range X for the terminal. For example, the listening range X can be configured for the terminal through predefined, high-layer signaling, or dynamic signaling.

[0129] Furthermore, the terminal can independently determine the coverage angle of each resource in the configured first resource set. That is, the beam width that needs to be covered when sending the first SRS on each resource. Thus, the terminal can be given the freedom to implement the beam. For example, assuming X = 180 degrees and the first resource set includes 6 resources, each resource can sweep 30 degrees on average.

[0130] For another example, assuming X = 180 degrees, the terminal can scan 180 degrees for each resource when sending the first SRS.

[0131] For still another example, assuming X = 180 degrees and the first resource set includes 9 resources, the terminal can decide that one resource scans 100 degrees when sending the first SRS, and the remaining 8 resources each scan 10 degrees.

[0132] In a variant, in step 102, if it is determined to send the first SRS and the network has pre-configured a beam direction, the terminal can use the resources in the first resource set to send the first SRS according to the configured beam direction. This is beneficial for the network's interference management.

[0133] As described above, by adopting this implementation solution, a suitable mechanism is provided to configure the SRS so that it can perform the sensing function, and it is ensured that the sensing result is successfully reported, enabling the terminal and the network side to reliably implement the sensing function based on the SRS. Specifically, a binding indication relationship is established between the SRS for sensing (i.e., the first SRS) and the PUCCH (e.g., the first PUCCH), enabling the terminal to report the sensing result to the network device through the uplink channel and ensuring the reliable implementation of the sensing function by both parties.

[0134] Furthermore, the SRS resource for sensing is configured through the second information to ensure that the terminal can use the first SRS to perform the sensing function.

[0135] Furthermore, the length / granularity / repetition transmission of the resources in the first resource set is different from that of the resources in the second resource set, which is beneficial to improving the sensing accuracy and ensuring the reliable implementation of the sensing function.
