Description

Technical Field

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

[0002] In a system of the fifth-generation mobile communications technology (abbreviated as 5G), the existing protocol stipulates that the functional uses of the sounding reference signal (SRS) mainly include four categories: 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 (antenna switching).

[0003] Future protocols may use SRS for the function of sensing. 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. For example, when the SRS configured to perform the sensing function collides with other data transmissions, the existing protocol cannot provide a suitable conflict handling mechanism. Summary of the Invention

[0029] Compared with the prior art, the technical solution of the embodiment of the present application has the following beneficial effects:

[0036] Figure 2 It is a schematic structural diagram of a communication device according to an embodiment of the present application. Detailed implementation manners

[0037] 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 will be given with reference to the accompanying drawings.

[0038] Figure 1 It is a flowchart of a communication method according to an embodiment of the present application.

[0039] This implementation solution can be applied to a 5G system, for example, to an application scenario where SRS in the 5G system is configured for sensing. In the sensing scenario, the terminal can send SRS and receive the echo signal of 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.

[0040] In specific implementation, the communication method provided in the following steps S101 to S102 can be executed by a chip with communication functions in the terminal, or can be executed by the baseband chip in the terminal.

[0041] Specifically, referring to Figure 1 , the communication method described in this implementation solution may include the following steps:

[0042] Step S101: Receive first information, where the first information is used to indicate the transmission of a first channel sounding reference signal, and the first channel sounding reference signal is a channel sounding reference signal for sensing;

[0043] Step S102: If a collision occurs between the first channel sounding reference signal and other data transmissions, discard or send the first channel sounding reference signal.

[0044] In some embodiments, the first SRS may be a periodic (P) SRS, also known as a statically scheduled SRS. Specifically, all parameters whose time domain type (also known as time domain characteristic) is configured as periodic SRS resources are configured by higher layer signaling, and the terminal transmits periodically according to the configured parameters. In this example, the first information in step S101 may be carried by higher layer signaling, such as by Radio Resource Control (RRC) signaling.

[0045] In some embodiments, the first SRS may be a semi-persistent (SP) SRS, also known as a semi-statically scheduled SRS. Specifically, the time domain type configured as semi-persistent SRS resources is also transmitted periodically during the activation period. The difference between it and the periodic SRS is that the terminal does not transmit the SRS after receiving the higher layer signaling configuration regarding the semi-persistent SRS resources, and only starts to transmit the first SRS corresponding to the semi-persistent SRS resources periodically after receiving the activation signaling regarding the semi-persistent SRS resources sent by the Medium Access Control (MAC) layer. It stops transmitting the first SRS after receiving the deactivation command of the semi-persistent SRS resources sent by the MAC layer. In this example, the first information in step S101 may include the activation signaling and be carried by MAC layer signaling. Further, the terminal may also receive RRC signaling to obtain the configuration information of the first SRS.

[0046] In some embodiments, the first SRS may be an aperiodic (A) SRS. Specifically, the time domain type configured as aperiodic SRS resources is activated by Downlink Control Information (DCI). Each time the terminal receives an SRS trigger signaling that triggers the aperiodic SRS resources, it performs one transmission of the first SRS corresponding to the triggered SRS resources. In this example, the first information in step S101 may include the trigger signaling and be carried by DCI. Further, the terminal may also receive RRC signaling to obtain the configuration information of the first SRS.

[0047] Further, in step S102, the first SRS may be discarded or transmitted according to a preset priority rule. The preset priority rule may be determined in advance by means of protocol definition, predefined or preconfigured. In some embodiments, the preset priority rule may include the priority ranking between the first SRS and other data. Correspondingly, the terminal executing this embodiment determines whether to transmit the first SRS in this transmission according to the priority ranking in step S102. In some embodiments, the preset priority rule may be implicitly indicated by enumeration, that is, the protocol may directly stipulate that the first SRS is transmitted (or the first SRS is discarded) when a collision occurs between the first SRS and other data. Correspondingly, when executing step S102, the terminal does not need to judge whether to transmit the first SRS according to the preset priority rule by itself, but directly transmits (or discards) the first SRS according to the protocol stipulation.

[0048] In a specific implementation, the SRS may be classified into two categories according to its use (also called 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). Among them, the use may also be configured by carrying it through higher layer signaling.

[0049] In step S102, if a collision occurs between the first SRS and the second SRS, the first SRS may be transmitted or discarded according to the priority ranking between the first SRS and the second SRS.

[0050] Specifically, the collision between the first SRS and the second SRS may specifically refer to the collision of the resources for carrying the first SRS and the resources for carrying the second SRS, that is, the first SRS and the second SRS overlap in time domain resources. For example, under the same carrier component (CC), the first SRS and the second SRS overlap at least in one symbol.

[0051] It can also be understood that the first SRS and the second SRS overlap in the same time unit. The time unit may be the communication granularity of the terminal and the network in the time domain. For example, the time unit may be a time slot, a mini-slot (that is, a time duration unit shorter than a time slot), a subframe, a symbol, a frame, etc. The same time unit means the same time unit, such as the first SRS and the second SRS are both configured to be transmitted in symbol 1.

[0052] Further, according to the priority ranking between the first SRS and the second SRS, if the first SRS has the highest priority, then the first SRS is sent at the time unit where a collision occurs or directly sent, and at the same time, the second SRS is discarded at the time unit where a collision occurs or directly discarded; otherwise, the first SRS is discarded at the time unit where a collision occurs or directly discarded, and the second SRS is sent or the second SRS is sent at the time unit where a collision occurs.

[0053] In some embodiments, the priority ranking between the first SRS and the second SRS may not consider the time domain characteristics, but simply be determined according to the use of the SRS.

[0054] For example, it can be defined that the priority of the SRS for sensing (i.e., the first SRS) is higher than the priority of the SRS for other uses (i.e., the second SRS).

[0055] In step S102, the first SRS is sent at the overlapping symbol or directly sent, and the second SRS is not sent or not sent at the overlapping symbol. Further, the second SRS of the overlapping symbol can be discarded.

[0056] For another example, it can be defined that the priority of the SRS for sensing (i.e., the first SRS) is lower than the priority of the SRS for other uses (i.e., the second SRS).

[0057] In step S102, the second SRS is sent at the overlapping symbol or directly sent, and the first SRS is not sent or not sent at the overlapping symbol. Further, the first SRS of the overlapping symbol can be discarded.

[0058] In some embodiments, the priority ranking between the first SRS and the second SRS can be jointly determined according to the time domain characteristics and the use of the SRS.

[0059] Specifically, the logic for joint determination can be, for example: determining the priority ranking with the time domain characteristics as the primary condition, and the first SRS and the second SRS with the same time domain characteristics determine the priority ranking according to the use.

[0060] For example, if a non-periodic SRS collides with a semi-persistent or periodic SRS, then the semi-persistent or periodic SRS of the overlapping symbol is not transmitted, regardless of whether the semi-persistent or periodic SRS is the first SRS or the second SRS. If a semi-persistent SRS collides with a periodic SRS, then the periodic SRS of the overlapping symbol is not transmitted, regardless of whether the periodic SRS is the first SRS or the second SRS.

[0061] Further, if the first SRS and the second SRS of the overlapping symbol have the same time domain characteristics, the priority is determined according to the use.

[0062] For example, the periodic SRS for sensing of overlapping symbols has a higher priority than the periodic SRS transmission for obtaining uplink channel information in a non-codebook uplink transmission scheme. Another example is that when the semi-persistent SRS for obtaining uplink channel information based on a codebook uplink transmission scheme overlaps with the semi-persistent SRS for sensing in the time domain, the terminal should not send the semi-persistent SRS for sensing configured in the same symbol, but only send the semi-persistent SRS for obtaining uplink channel information based on a codebook uplink transmission scheme.

[0063] In a possible example, the priority ranking can be further refined as follows: the priority of the aperiodic SRS for obtaining uplink channel information based on a codebook uplink transmission scheme is higher than that of the semi-persistent SRS for sensing; the priority of the semi-persistent SRS for obtaining downlink channel information based on SRS antenna switching is higher than that of the periodic SRS for sensing; the priority of the periodic SRS for sensing is higher than that of the periodic SRS for uplink beam management.

[0064] In some embodiments, the priority ranking between the first SRS and the second SRS can be specified by a protocol. Alternatively, it can also be configured by the network. Or, it can be pre-determined by the base station and the terminal.

[0065] In a specific implementation, in step S102, if a collision occurs between the first SRS and the Physical Uplink Control Channel (PUCCH for short), the first SRS is sent or discarded according to the priority ranking between the first SRS and the PUCCH.

[0066] Specifically, a collision between the first SRS and the PUCCH can specifically mean that the first SRS and the PUCCH overlap in time domain resources. For example, under the same carrier condition, the first SRS and the PUCCH overlap in at least one symbol.

[0067] Furthermore, according to the priority ranking between the first SRS and the PUCCH, if the priority of the first SRS is the highest, the first SRS is sent in the time unit where the collision occurs or the first SRS is directly sent, and the PUCCH is directly discarded; otherwise, the first SRS is discarded in the time unit where the collision occurs or the first SRS is directly discarded, and the PUCCH is sent.

[0068] In some embodiments, the priority ranking between the first SRS and the PUCCH can be determined according to the time domain characteristics of the first SRS and the data carried by the PUCCH.

[0069] Specifically, the priority of the semi-persistent and periodic first SRS is lower than that of the PUCCH.

[0070] For example, for the overlap of the first SRS and PUCCH on a carrier condition, for the semi-persistent or periodic first SRS, discard the first SRS of the overlapping symbols.

[0071] Furthermore, the priority of the aperiodic first SRS is higher than the priority of the PUCCH carrying periodic or semi-persistent data.

[0072] For example, for the overlap of the first SRS and PUCCH on a carrier condition, for the aperiodic first SRS, if the PUCCH carries semi-persistent or periodic Channel State Information (CSI), or the PUCCH carries semi-persistent or periodic Layer 1 Signal to Interference and Noise Ratio (L1-SINR) or Layer 1 Reference Signal Received Power (L1-RSRP), then discard the data carried by the PUCCH in the overlapping symbols.

[0073] In a typical application scenario, the priority sorting between the first SRS and PUCCH can follow the discard rules of the existing protocol:

[0074] 1) When the semi-persistent and periodic first SRS and the PUCCH carrying only CSI reports are configured in the same symbol, or when the semi-persistent and periodic SRS and the PUCCH carrying only L1-RSRP reports are configured in the same symbol, the terminal should not send the first SRS.

[0075] 2) After the semi-persistent first SRS or periodic first SRS or aperiodic first SRS is triggered, when it is sent in the same symbol as the PUCCH carrying Hybrid Automatic Repeat reQuest (HARQ) acknowledgement (ACK) and / or scheduling request (SR), the terminal should not send the first SRS.

[0076] 3) For the case where the first SRS is not sent due to overlap with the PUCCH, only discard the first SRS symbols overlapping with the PUCCH.

[0077] 4) After the aperiodic first SRS is triggered, when it is in the same symbol as the PUCCH carrying semi-persistent / periodic CSI reports or only carrying semi-persistent / periodic L1-RSRP reports, the terminal should not send the PUCCH.

[0078] In some embodiments, the priority order between the first SRS and the PUCCH can be determined according to the use of the first SRS, without paying attention to the priority of the sensing service or the content carried by the PUCCH.

[0079] For example, it can be defined that the priority of the first SRS is higher than that of the PUCCH.

[0080] In other words, in step S102, the first SRS is always sent in the overlapping symbols or directly sent, regardless of the time domain characteristics of the first SRS or the data carried by the PUCCH.

[0081] For another example, it can be defined that the priority of the first SRS is lower than that of the PUCCH.

[0082] In other words, in step S102, the first SRS is always discarded in the overlapping symbols or directly discarded, regardless of the priority of the sensing service associated with the first SRS or the data carried by the PUCCH.

[0083] In some embodiments, the priority order between the first SRS and the PUCCH can be determined according to the priority of the service associated with the first SRS (e.g., the sensing service) and the priority of the data carried by the PUCCH.

[0084] Specifically, the sensing service may also have a priority similar to the Quality of Service (QoS) of the sidelink. For example, a service can be split into a high-priority sensing service and a low-priority sensing service with a threshold. The first SRS can be associated with the service.

[0085] Furthermore, the data carried by the PUCCH has a priority order, and the corresponding PUCCH also has a priority. The low-priority PUCCH can be, for example, the PUCCH carrying semi-persistent or periodic CSI reports, L1-SINR, and L1-RSRP. The PUCCH carrying other data can be classified as a high-priority PUCCH.

[0086] For example, the priority order can be defined as: high-priority sensing service > high-priority PUCCH > low-priority sensing service > low-priority PUCCH. In practical applications, other orders can also be defined as needed.

[0087] In a specific implementation, in step S102, if a collision occurs between the first SRS and the Physical Uplink Shared Channel (PUSCH), the first SRS is sent or discarded according to the priority order between the first SRS and the PUSCH.

[0088] Specifically, the collision between the first SRS and PUSCH may specifically refer to that the first SRS and PUSCH are configured in the same time unit. For example, under the same carrier condition, the first SRS and PUSCH are configured in the same symbol.

[0089] Furthermore, according to the priority sorting between the first SRS and PUSCH, if the priority of the first SRS is the highest, the first SRS is sent in the time unit where the collision occurs; otherwise, the first SRS is discarded in the time unit where the collision occurs, and the data carried by the PUSCH is sent.

[0090] In some embodiments, the priority sorting between the first SRS and PUSCH can be determined according to the communication scenario associated with the PUSCH.

[0091] Specifically, the communication scenarios may include: eMBB (Enhanced Mobile Broadband), uRLLC (Ultra-Reliable and Low-Latency Communications), and mMTC (Massive Machine Type Communications). Among them, the eMBB scenario is designed for high-capacity and high-rate broadband data services, aiming to provide users with a faster and more stable wireless broadband connection experience. The main feature of eMBB is to provide high-rate data transmission, which is suitable for the transmission of large-capacity data such as high-definition video, virtual reality, cloud games, and downloads. The uRLLC scenario is to meet the requirements for low-latency and high-reliability communications, such as real-time control, medical, and autonomous driving applications. The main feature of uRLLC is to provide extremely low latency and high reliability to ensure the reliability and stability of real-time and critical applications. The mMTC scenario aims to support the connection of a large number of Internet of Things devices to meet the connection needs of a large number of devices, such as smart home, smart city, and industrial automation applications. The main features of mMTC are the connectivity of a large number of devices, low power consumption, and low cost.

[0092] In a typical application scenario, the priority sorting between the first SRS and PUSCH can follow the discard rules of the existing protocol:

[0093] 1) If the PUSCH associated with the eMBB scenario and the first SRS are scheduled simultaneously in the same time slot, only the first SRS is supported to be scheduled after the PUSCH associated with the eMBB scenario.

[0094] 2) If the PUSCH associated with the uRLLC scenario overlaps with the first SRS, discard the first SRS on a symbol-wise basis.

[0095] In some embodiments, the priority order between the first SRS and the PUSCH can be determined according to the use of the first SRS.

[0096] For example, it can be defined that the priority of the first SRS is higher than that of the PUSCH.

[0097] In other words, in step S102, the first SRS is always transmitted in the overlapping symbols, regardless of the time-domain characteristics of the first SRS and without considering the communication scenario associated with the PUSCH.

[0098] For another example, it can be defined that the priority of the first SRS is lower than that of the PUSCH.

[0099] In other words, in step S102, the first SRS is always discarded in the overlapping symbols or directly discarded, regardless of the time-domain characteristics of the first SRS and without considering the communication scenario associated with the PUSCH.

[0100] In a specific implementation, before step S101, this implementation scheme may further include the step of: receiving second information, where the second information includes a plurality of candidate first resource sets, and the resources in the first resource set are used to transmit the first SRS.

[0101] Specifically, the network can pre-configure a plurality of 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 transmit the first SRS.

[0102] In some embodiments, the time-domain granularity of the first SRS for sensing can be longer than that of the second SRS for other traditional uses, and specifically can depend on the accuracy requirements of velocity or angle.

[0103] 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.

[0104] 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.

[0105] For yet another example, multiple time-domain granularities can be configured in a mixed manner, such as a resource can include x time slots and y symbols.

[0106] In one embodiment, the resources in at least one first resource set may be transmitted periodically and repeatedly.

[0107] Specifically, a repetition factor may be newly added to the second information to indicate the number of times of repeated transmission of the resources in the first resource set.

[0108] 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.

[0109] 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, an independent configuration of the SRS for sensing may be given in the second information.

[0110] 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 and may also be configured as the second resource set for other uses. The second resource set is used to send the second SRS.

[0111] In some embodiments, the second information may be carried by high-layer signaling, for example, carried by RRC signaling.

[0112] In a specific implementation, in step 102, if it is determined to send the first SRS, the first SRS may further be sent according to the default beam direction.

[0113] Specifically, when the network does not configure a beam direction for the first SRS, the terminal may send the first SRS according to the default beam direction to successfully perform the sensing function.

[0114] In some embodiments, the default beam direction may be the beam direction of the most recent successful sensing of an object. For example, in an intrusion detection scenario, the beam direction of the most recent successful sensing of an object may be used as the default beam direction of the current first SRS. Intrusion detection may be, for example, airspace detection, such as the detection of a drone invading a private residence.

[0115] In some embodiments, the default beam direction may be determined according to the configured listening range.

[0116] 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 means, through high-layer signaling, or through dynamic signaling. Among them, X can be angular information or location information, which can be configured by the network side through high-layer signaling or determined in a predefined form.

[0117] Furthermore, the terminal can independently determine the coverage angle of each resource in the configured first resource set. That is, the beam width 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 an average of 30 degrees.

[0118] For another example, assuming X = 180 degrees, when the terminal sends the first SRS, each resource can sweep 180 degrees.

[0119] For yet another example, assuming X = 180 degrees and the first resource set includes 9 resources, the terminal can decide that one resource sweeps 100 degrees when sending the first SRS, and the remaining 8 resources each sweep 10 degrees.

[0120] In a variant, the default beam can also be pre-configured by the network, which is beneficial to the network's interference management.

[0121] As described above, when the SRS is configured to perform the sensing function and collides with other data transmissions, the present implementation can provide a suitable conflict handling mechanism to ensure that the terminal correctly transmits data and improve communication reliability. Further, determining whether to discard the first SRS according to the preset priority rule is beneficial to ensuring that high-priority data is preferentially transmitted. Among them, the data can include the SRS, the data carried by the PUCCH, and the data carried by the PUSCH.
