Description

Communication method and device, and computer-readable storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 27, 2023, with application number 202311836999.9 and invention name “Communication method and device, computer-readable storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device, and a computer-readable storage medium. Background Art

[0003] In the Fifth Generation mobile communications (5G) system, existing protocols specify that the Sounding Reference Signal (SRS) functions fall into four main categories: uplink beam management, uplink channel information acquisition based on codebook uplink transmission schemes (codebook), uplink channel information acquisition based on non-codebook uplink transmission schemes (non-codebook), and downlink channel information acquisition based on SRS antenna switching (antenna switching).

[0004] Future protocols may utilize SRS for sensing. Therefore, it's crucial to address how to configure SRS to perform this sensing function, as well as the potential protocol modifications required to implement this functionality. This will ensure that both the terminal and the network can reliably implement SRS-based sensing. For example, in scenarios where the terminal transmits and receives data independently, existing protocols prevent the terminal from correctly reporting sensing results to the base station or other terminals.

[0050] FIG2 is a schematic structural diagram of a communication device according to an embodiment of the present application;

[0051] FIG3 is a schematic structural diagram of another communication device according to an embodiment of the present application. DETAILED DESCRIPTION

[0052] In order to make the above-mentioned objectives, features and beneficial effects of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0053] FIG1 is a flow chart of a communication method according to an embodiment of the present application.

[0054] This embodiment can be applied to 5G systems, for example, in application scenarios where SRS is configured for sensing in 5G systems. In the sensing scenario, the terminal can send an SRS and receive an echo signal of the SRS, and then perform a sensing algorithm on the echo signal. The processed sensing result can be reported to the base station or sensing function (SF) through the uplink channel. The sensing function can be a network element of the core network. Alternatively, the terminal can send an SRS for sensing (referred to as the first SRS), and the base station (for example, gNB) receives the echo signal. Alternatively, terminal A can send the first SRS, and terminal B can receive 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.

[0055] In a specific implementation, in the communication method provided by 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 by a 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 by a baseband chip in the network device.

[0056] Specifically, with reference to FIG1 , the communication method according to this embodiment may include the following steps:

[0057] In step S101, a network device sends first information to a terminal. The first information includes trigger signaling, the trigger signaling is used to trigger the transmission of a first SRS, the first SRS is an SRS for sensing, and the first SRS is associated with a first physical uplink control channel (PUCCH). Accordingly, the terminal receives the first information.

[0058] In step S102, the terminal sends a first SRS and uses a first PUCCH to report a sensing result. Correspondingly, the network device uses the first PUCCH to receive the sensing result.

[0059] In some embodiments, the first SRS may include one of the following according to time domain characteristics (also known as time domain type): periodicity (P) SRS (also known as statically scheduled SRS), semi-persistent (SP) SRS (also known as semi-statically scheduled SRS), and aperiodicity (A) SRS.

[0060] All parameters configured as periodic SRS resources are configured by higher-layer signaling (eg, Radio Resource Control (RRC) signaling), and the terminal periodically transmits according to the configured parameters.

[0061] A semi-persistent SRS resource is also transmitted periodically during its activation period. This differs from periodic SRS in that the terminal does not transmit SRS after receiving high-layer signaling configuration for the semi-persistent SRS resource. Instead, it begins periodically transmitting the first SRS corresponding to the semi-persistent SRS resource only after receiving activation signaling from the Medium Access Control (MAC) layer regarding the semi-persistent SRS resource. Transmission of the first SRS ceases upon receiving a deactivation command for the semi-persistent SRS resource from the MAC layer.

[0062] The aperiodic SRS resource is activated via downlink control information (DCI). Each time the terminal receives SRS trigger signaling for triggering the aperiodic SRS resource, it transmits the first SRS corresponding to the triggered SRS resource. In this example, the first information in step S101 may include the trigger signaling, carried by the DCI. Furthermore, the terminal may also receive RRC signaling to obtain configuration information for the first SRS (for details, see the description of the second information below).

[0063] Next, the configuration and uplink reporting of the first SRS in this application will be described in detail by taking the aperiodic SRS as an example.

[0064] In step S102, for the terminal's self-transmitting and self-receiving mode, after sending the first SRS, the terminal will receive its echo, perform a sensing algorithm analysis, and report the sensing results to the base station or other terminal. In this scenario, the sensing results need to be shared with the base station or other terminals, and the content perceived by different devices can be different.

[0065] 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 perception result. For example, when the DCI triggers the first SRS, the first PUCCH resource can be configured for feedback of the perception result.

[0066] Specifically, the first information may include a first indication field, used to indicate the first PUCCH.

[0067] Furthermore, 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.

[0068] In some embodiments, DCI used for scheduling uplink transmissions (i.e., DCI formats 0_1 and 0_2) do not originally contain a PUCCH resource indicator (PRI) field. Therefore, in this embodiment, a new PRI field is added to this type of DCI to carry the PUCCH report of the first SRS sensing result.

[0069] For example, a new format of DCI may be designed for scheduling uplink transmission, and the new format of DCI includes a PRI indication field, where the PRI indication field is used to indicate the resources of the first PUCCH.

[0070] In some embodiments, for DCI used for scheduling downlink transmission (ie, DCI in format 1_1 and format 1_2), the first indication field may reuse the original PRI indication field in this type of DCI.

[0071] Specifically, the first indication field may be used to indicate a first PUCCH and to indicate a second PUCCH, where the second PUCCH is used to carry a feedback result of a physical downlink shared channel (PDSCH for short).

[0072] That is, the first indication field indicates two PUCCH resources simultaneously, namely the first PUCCH resource and the second PUCCH resource. Accordingly, the PDSCH Hybrid Automatic Repeat reQuest (HARQ) acknowledgment (ACK) and the sensing result are reported on different PUCCHs respectively.

[0073] For example, the first indication field may be increased from an existing smaller number of bits (eg, 3 bits) to 6 bits, wherein the upper 3 bits are used to indicate the second PUCCH and the lower 3 bits are used to indicate the first PUCCH.

[0074] For another example, in the 6-bit first indication field, the upper 3 bits may correspond to the PUCCH resource indication carrying the perception result, and the lower 3 bits may correspond to the PUCCH resource indication carrying the PDSCH HARQ-ACK.

[0075] In some embodiments, for DCI used to schedule downlink transmission (ie, DCI in format 1_1 and format 1_2), the original PRI indication field of this type of DCI may be reused to indicate the first PUCCH.

[0076] Specifically, the first information may include a first indication field and a second indication field, wherein the first indication field is used to indicate the first PUCCH, and the second indication field is used to indicate the second PUCCH, and the first indication field and the second indication field may be two independent PRI fields.

[0077] That is, two PRI indication fields are used to indicate two PUCCHs respectively, so that PDSCH HARQ-ACK and sensing results are reported separately on different PUCCHs.

[0078] For example, the PRI indication field in the first information can be increased to 6 bits, and these 6 bits are divided into two independent fields, where 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.

[0079] In some embodiments, for DCI used to schedule downlink transmission (ie, 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.

[0080] Specifically, the first PUCCH can be used to carry the sensing result and the PDSCH feedback result. That is, the PDSCH HARQ-ACK and the sensing result are reported on the same PUCCH. Optionally, the order of the PDSCH HARQ-ACK and the sensing result in the uplink control information (UCI) can be PDSCH HARQ-ACK first and the sensing result second, or the sensing result first and the PDSCH HARQ-ACK second.

[0081] In this example, the sensing result can be considered as a new CSI content, such as a new Channel State Information-Reference Signal (CSI-RS).

[0082] As described above, the implementation of reporting the PDSCH HARQ-ACK and perception results separately on two PUCCHs can be preferably applied to scenarios where the processing timeline does not allow. Specifically, considering the processing capability of the terminal, if the completion time from sending the first SRS to receiving the echo, and then processing it into perception information packaging to obtain the perception result is far away from the completion time of processing the PDSCH feedback result, it is considered to be a scenario where the processing timeline does not allow. In this case, it is preferred to report the perception result and PDSCH feedback result separately on two PUCCHs, which helps to reduce latency.

[0083] If the terminal's processing capability allows the generation of the sensing result close to the generation of the PDSCH feedback result, that is, if the terminal can complete both the PDSCH HARQ-ACK and the sensing result before the PUCCH resource indicated by the PRI indicator field arrives, then this scenario is considered to be within the processing schedule. In this case, it is preferred to report the sensing result and the PDSCH feedback result in the same PUCCH, which helps save signaling overhead and reduce communication load.

[0084] In one specific implementation, the association between the first SRS and the first PUCCH can be configured via higher-layer signaling. For example, an aperiodic SRS for sensing can be configured via RRC signaling to be directly associated with a PUCCH. Specifically, one SRS resource set can be associated with one PUCCH resource, or one or more SRS resources can be associated with one PUCCH resource.

[0085] In a specific implementation, before step S101, the embodiment may further include the following steps: the network device sends second information to the terminal, the second information including multiple candidate first resource sets, the resources in the first resource set being used to transmit the first SRS. Accordingly, the terminal receives the second information.

[0086] Specifically, the network may 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.

[0087] In some embodiments, the time-domain granularity of the first SRS used for perception may be longer than the time-domain granularity of the second SRS traditionally used for other purposes, which may depend on the accuracy requirement of velocity or angle.

[0088] For example, the length of at least one resource in the first resource set may 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 resource used for sensing the first SRS, the higher the sensing accuracy. Accordingly, the resources in the first resource set may be configured across multiple time slots.

[0089] For another example, at least one resource in the first resource set is configured in units of symbols. For example, the resource may be configured to start at the first symbol of the first time slot and end at the fifth symbol of the second time slot.

[0090] For another example, a variety of time domain granularities may be mixed and configured, such as one resource may include x time slots and y symbols.

[0091] In one embodiment, resources in at least one first resource set may be transmitted repeatedly and periodically.

[0092] Specifically, a repetition factor may be added to the second information to indicate the number of repeated transmissions of the resources in the first resource set.

[0093] For example, the length of the resources in the first resource set may be configured to be 6 OFDM symbols, and the transmission may be repeated for 4 cycles.

[0094] In some embodiments, the first resource set may be configured to be dedicated to the first SRS. For example, similar to the SRS used for positioning, the configuration of an independent SRS used for sensing may be given in the second information.

[0095] In some embodiments, the first resource set may be a resource set configured for sensing. For example, a new type (i.e., sensing type) may be added to the usage of an existing SRS resource set. Thus, the SRS resource set in RRC signaling may be configured as a first resource set for sensing, or as a second resource set for other purposes. The second resource set is used to transmit a second SRS.

[0096] In some embodiments, the second information may be carried via higher layer signaling, for example, via RRC signaling.

[0097] In one specific implementation, the SRS can be divided into two categories based on its purpose (also known as function) into a first SRS for sensing and a second SRS for other purposes. Other purposes may include uplink beam management, uplink channel information acquisition based on a codebook uplink transmission scheme (codebook), uplink channel information acquisition based on a non-codebook uplink transmission scheme (non-codebook), and downlink channel information acquisition based on SRS antenna switching (antenna switching).

[0098] Furthermore, the number of existing SRS resource sets can be increased to configure a dedicated first resource set for the first SRS. For example, the network side can pre-configure multiple candidate SRS resource sets, including at least one candidate first resource set and multiple candidate second resource sets. 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.

[0099] In a specific implementation, taking non-periodic SRS as an example, the trigger signaling can correspond to the first resource set. Every time the terminal receives the trigger signaling for triggering the non-periodic SRS resource, it sends the first SRS corresponding to the triggered SRS resource (for example, the resource in the first resource set).

[0100] Correspondingly, in step S102, the terminal sends the first SRS using the resources in the first resource set corresponding to the trigger signaling.

[0101] Furthermore, the trigger signaling may include a third indication field, used to indicate the first resource set.

[0102] In some embodiments, the traditional association between the trigger state and the SRS resource set can be maintained. Specifically, the SRS trigger signaling in the traditional DCI usually contains 2 bits, which can indicate the trigger state and then trigger the sending of the SRS resource set associated with the trigger state. Optionally, the SRS resource set or the PUCCH resource associated with the SRS resource can be configured by the network side through high-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.

[0103] Furthermore, specifically in this example, in addition to indicating the first resource set, the first indicator field can also be used to indicate the second resource set, which is used to transmit other SRSs (i.e., the second SRS) in addition to the first SRS. Accordingly, the number of bits in the third indicator field in the SRS trigger signaling of the DCI can be increased from 2 bits to, for example, 4 bits. In this 4-bit third indicator 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.

[0104] In some embodiments, the third indication field may be an independent trigger indication field. Accordingly, the trigger signaling may include the third indication field (a newly added field compared to the SRS trigger signaling in the existing DCI) and a fourth indication field (similar to the status indication in the SRS trigger signaling in the existing DCI), where the fourth indication field is used to indicate the second resource set.

[0105] For example, the trigger signaling in the first information can be increased to 4 bits, and these 4 bits are divided into two independent fields, where the 2-bit field serves as the third indication field to indicate the first resource set, and the remaining 2-bit field serves as the fourth indication field to indicate the second resource set.

[0106] In a specific implementation, the second information may include a first offset value, which is used to determine the time interval (slot offset) between receiving the trigger signaling and performing PUCCH transmission.

[0107] Specifically, unlike the offset value configured for the second SRS (for example, through RRC signaling), which is the time interval between triggering the second SRS transmission (for example, through DCI triggering) and the actual second SRS transmission by the terminal, the first offset value in this embodiment is the time interval between the first SRS and PUCCH.

[0108] For example, the length of the first offset value may be greater than the length of the offset value configured for the second SRS, so that the terminal may have sufficient time to receive the echo signal and process the perception information.

[0109] In some embodiments, the first offset value may be configured on a resource-by-resource basis. That is, the configuration of the first offset value may be implemented resource-wise. The resource may be a time slot, a symbol, or other time-domain resource granularity, which is not limited in the present invention.

[0110] Specifically, compared to the resources in the second resource set, which only need to select the one with the best signal for feedback during communication, in this embodiment, the resources in the first resource set are used for sensing, so the resources in the first resource set need to send the first SRS in different directions. Furthermore, the echoes fed back from different directions are different (for example, the time of arrival at the terminal is different), so an appropriate first offset value can be configured for each resource in the first resource set.

[0111] For example, the first offset value can be associated with a beam direction. Assuming that the first resource set includes resource 1, resource 2, and resource 3, the terminal uses resource 1 to send the first SRS toward beam direction 1, uses resource 2 to send the first SRS toward beam direction 2, and uses resource 3 to also send the first SRS toward beam direction 2. Accordingly, resource 1 can correspond to a first offset value of 1, and resources 2 and 3 can correspond to a first offset value of 2.

[0112] In one specific implementation, the first information may include a second offset value, wherein the second offset value may be indicated by a first flexible indication field. Further, the time interval between receiving the trigger signaling and performing the PUCCH transmission may be jointly determined based on the first offset value and the second offset value.

[0113] Similarly, the first information may also include a third offset value configured for the second SRS. The time interval between triggering the second SRS transmission and actually transmitting the second SRS may be jointly determined based on the offset value configured for the second SRS in the second information and the third offset value.

[0114] In some embodiments, the second offset value and the third offset value may share the same dynamic indication field.

[0115] Specifically, the first dynamic indication field can be used to indicate the second offset value and the third offset value.

[0116] For example, a set of candidate values ​​for the first dynamic indication field may be predefined, preconfigured by the network, or specified by a protocol, and the first dynamic indication field in the first information may select {2, 8} from the set to indicate to the terminal. Accordingly, the terminal determines the third offset value to be 2 and the second offset value to be 8.

[0117] In some embodiments, the second offset value and the third offset value may each have an independent dynamic indication field.

[0118] Specifically, the first information may further include a second dynamic indication field, which is used to indicate the third offset value.

[0119] For example, a set of candidate values ​​for the first dynamic indication field may be predefined, preconfigured by the network, or specified by a protocol: {2, 4, 6, 8}; and a set of candidate values ​​for the second dynamic indication field may be {2, 4, 6}. The first dynamic indication field in the first information may select {8} from {2, 4, 6, 8} and indicate it to the terminal, while the second dynamic indication field may select {2} from {2, 4, 6} and indicate it to the terminal. Accordingly, the terminal determines the third offset value to be 2 and the second offset value to be 8.

[0120] For another example, the first dynamic indication field in the first information can select {6} from {2, 4, 6, 8} to indicate to the terminal, and the second dynamic indication field can select {6} from {2, 4, 6} to indicate to the terminal. Accordingly, the terminal determines that the third offset value and the second offset value are both 6.

[0121] In a variation, the third offset value may be omitted, that is, the second offset value may be used to determine both the time interval of the first SRS and the time interval of the second SRS.

[0122] In one specific implementation, before executing step S101, this embodiment may further include the following steps: the terminal reports capability information to the network device, where the capability information includes a time interval for sensing, where 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.

[0123] Furthermore, 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 is configured so as not to exceed the terminal capability, such as configuring the specific value of the first offset value at a time interval not less than a minimum time interval.

[0124] For example, a parameter k3 may be added to the capability information to indicate the time interval between SRS (eg, the first SRS) and PUCCH transmission.

[0125] In a specific implementation, in step 102, if it is determined to send the first SRS, the first SRS may be further sent according to a default beam direction.

[0126] Specifically, when the network does not configure a beam direction for the first SRS, the terminal may send the first SRS according to a default beam direction to successfully perform the perception function.

[0127] In some embodiments, the default beam direction may be the beam direction of the most recently successfully sensed object. For example, in an intrusion detection scenario, the beam direction of the most recently successfully sensed object may be used as the default beam direction for the current first SRS. Intrusion detection may be, for example, airspace detection, such as detecting a drone intruding into a private residence.

[0128] In some embodiments, the default beam direction may be determined according to the configured listening range.

[0129] Specifically, the network may pre-configure a monitoring range X for the terminal. For example, the monitoring range X may be configured for the terminal through pre-definition, high-layer signaling, or dynamic signaling.

[0130] Furthermore, the terminal can independently determine the coverage angle of each resource in the configured first resource set. In other words, the required beamwidth for each resource when transmitting the first SRS. This allows the terminal greater freedom in beam implementation. For example, assuming X = 180 degrees and the first resource set includes six resources, each resource can cover an average of 30 degrees.

[0131] For another example, assuming X=180 degrees, the terminal may scan 180 degrees for each resource when sending the first SRS.

[0132] For another example, assuming X=180 degrees, the first resource set includes 9 resources, then the terminal may decide to scan 100 degrees for one of the resources when sending the first SRS, and each of the remaining 8 resources scans 10 degrees.

[0133] In a variation, in step 102, if it is determined to send the first SRS and the network pre-configures a beam direction, the terminal may send the first SRS using resources in the first resource set according to the configured beam direction. This facilitates interference management in the network.

[0134] As described above, this embodiment adopts the method of providing a suitable mechanism to configure the SRS so that it can perform the perception function and ensure that the perception results are successfully reported, so that the terminal and the network side can reliably implement the perception function based on the SRS. Specifically, a binding indication relationship is established between the SRS used for perception (i.e., the first SRS) and the PUCCH (e.g., the first PUCCH), so that the terminal can report the perception results to the network device through the uplink channel, ensuring that both parties can reliably implement the perception function.

[0135] Furthermore, the SRS resources used for perception are configured through the second information, thereby ensuring that the terminal can use the first SRS to perform the perception function.

[0136] Furthermore, the length / granularity / repeated transmission of the resources in the first resource set are different from those in the second resource set, which is conducive to improving perception accuracy and ensuring that the perception function is reliably implemented.
