Detailed Description
In order to make the above objects, features and advantages of the present application more comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a flow chart of a communication method according to an embodiment of the present application.
The present embodiment can be applied to a 5G system, for example, to an application scenario in which SRS is configured for perception in a 5G system. In the sensing scene, the terminal can send SRS and receive the echo signal of SRS, and then perform sensing algorithm processing on the echo signal. The processed sensing result can be reported to a base station or Sensing Function (SF) through an uplink channel. The awareness function may be a network element of the core network. Alternatively, the terminal may transmit an SRS for sensing (referred to as a first SRS), and the base station (e.g., gNB) may receive the echo signal. Alternatively, the terminal a may transmit the first SRS, and the terminal B may receive the echo signal. The sensing result may be used by the terminal that transmits the first SRS, or used by the base station, or used by the SF, or used by other terminals.
In a specific implementation, the communication method provided in the following steps S101 to S102 may be executed by a chip with a communication function in the terminal, or may be executed by a baseband chip in the terminal.
Specifically, referring to fig. 1, the communication method according to the present embodiment may include the steps of:
Step S101, receiving first information, wherein the first information is used for indicating the transmission of a first channel sounding reference signal, and the first channel sounding reference signal is a channel sounding reference signal for sensing;
Step S102, if the first channel sounding reference signal collides with other data transmission, the first channel sounding reference signal is discarded or sent.
In some embodiments, the first SRS may be a periodic (periodicity, abbreviated P) SRS, also referred to as a statically scheduled SRS. Specifically, the time domain type (also referred to as time domain characteristics) is configured such that all parameters of the periodic SRS resource are configured by the higher layer signaling, and the terminal periodically transmits according to the configured parameters. In this example, the first information in step S101 may be carried by a higher layer signaling, such as a radio resource control (Radio Resource Control, abbreviated RRC) signaling.
In some embodiments, the first SRS may be a semi-persistent (SP) SRS, also referred to as a semi-statically scheduled SRS. Specifically, the time domain type is configured such that the semi-persistent SRS resource is also periodically transmitted during activation. It is different from the periodic SRS in that the terminal does not transmit an SRS after receiving a higher layer signaling configuration for the semi-persistent SRS resource, and periodically starts to transmit a first SRS corresponding to the semi-persistent SRS resource only after receiving an activation signaling for the semi-persistent SRS resource transmitted by a medium access control (Medium Access Control, MAC) layer. And stopping sending the first SRS after receiving a deactivation command of the semi-persistent SRS resource sent by the MAC layer. In this example, the first information in step S101 may include activation signaling, carried by MAC layer signaling. Further, the terminal may also receive RRC signaling to obtain configuration information of the first SRS.
In some embodiments, the first SRS may be an aperiodic (aperiodicity, abbreviated a) SRS. Specifically, the time domain type is configured such that the aperiodic SRS resource is activated through downlink control information (Downlink Control Information, abbreviated DCI). And each time the terminal receives the SRS trigger signaling triggering the aperiodic SRS resource once, performing first SRS transmission corresponding to the triggered SRS resource once. In this example, the first information in step S101 may include trigger signaling, carried through DCI. Further, the terminal may also receive RRC signaling to obtain configuration information of the first SRS.
Further, in step S102, the first SRS may be discarded or transmitted according to a preset priority rule. The preset priority rules may be predetermined by means of protocol definition, predefining or pre-configuring. In some embodiments, the preset priority rule may include a priority ranking between the first SRS and other data, and accordingly, the terminal executing the embodiment determines in step S102 whether the first SRS is transmitted in the present transmission according to the priority ranking. In some embodiments, the preset priority rule may implicitly indicate by means of enumeration, that is, the protocol may directly specify that the first SRS is transmitted (or the first SRS is discarded) when the first SRS collides with other data, and accordingly, the terminal does not need to determine whether to transmit the first SRS according to the preset priority rule by itself when executing step S102, but knows that the first SRS is transmitted (or discarded) according to the protocol specification.
In one implementation, SRS may be divided into two broad categories, a first SRS for sensing and a second SRS for other purposes by purpose (also called functionality). Other uses may include upstream beam management (beam management), codebook-based upstream channel information acquisition (codebook), non-codebook-based upstream channel information acquisition (non-codebook) for non-codebook based upstream transmission schemes, and SRS antenna switching-based downstream channel information acquisition (ANTENNA SWITCHING), among others. Wherein the use may also be configured by a higher layer signaling bearer.
In step S102, if the first SRS collides with the second SRS, the first SRS may be transmitted or discarded according to the priority ranking between the first SRS and the second SRS.
Specifically, collision of the first SRS and the second SRS may specifically mean that the resource for carrying the first SRS and the resource for carrying the second SRS collide, that is, the first SRS and the second SRS overlap on the time domain resource. For example, the first SRS and the second SRS overlap at least over one symbol under the same carrier element (Carrier component, abbreviated CC).
It can also be appreciated that the first SRS and the second SRS overlap (overlap) at the same time unit. The time units may be communication granularity of the terminal and the network in the time domain. For example, the time units may be slots, minislots (i.e., units of time length shorter than the slots), subframes, symbols, frames, etc. The same time unit refers to the same time unit, e.g., the first SRS and the second SRS are both configured to be transmitted in symbol 1.
Further, according to the priority order between the first SRS and the second SRS, if the priority of the first SRS is highest, the first SRS is sent in the time unit with collision or the first SRS is directly sent, and the second SRS is discarded in the time unit with collision or the second SRS is directly discarded, otherwise, the first SRS is discarded in the time unit with collision or the first SRS is directly discarded, and the second SRS is sent or the second SRS is sent in the time unit with collision.
In some embodiments, the prioritization between the first SRS and the second SRS may not take into account time domain characteristics, but may simply be determined according to the purpose of the SRS.
For example, it may be defined that the priority of SRS for sensing (i.e., the first SRS) is higher than the priority of SRS for other purposes (i.e., the second SRS).
In step S102, the first SRS is transmitted in the superimposed symbol or the first SRS is directly transmitted, and the second SRS is not transmitted or is not transmitted in the superimposed symbol. Further, the second SRS of the overlapping symbol may be discarded.
For another example, it may be defined that the priority of SRS for sensing (i.e., the first SRS) is lower than the priority of SRS for other purposes (i.e., the second SRS).
In step S102, the second SRS is transmitted in the superimposed symbol or the second SRS is directly transmitted, and the first SRS is not transmitted or the first SRS is not transmitted in the superimposed symbol. Further, the first SRS of the overlapping symbol may be discarded.
In some embodiments, the prioritization between the first SRS and the second SRS may be determined jointly based on the time domain characteristics and the purpose of the SRS.
Specifically, the logic of joint determination may be, for example, to determine a prioritization based on a first condition of time-domain characteristics, and to determine a prioritization based on the use of the first SRS and the second SRS of the same time-domain characteristics.
For example, if an aperiodic SRS collides with a semi-persistent or periodic SRS, then the semi-persistent or periodic SRS of the overlapping symbols is not transmitted, whether the semi-persistent or periodic SRS is the first SRS or the second SRS. If the semi-persistent SRS collides with the periodic SRS, the periodic SRS of the overlapping symbol is not transmitted, regardless of whether the periodic SRS is the first SRS or the second SRS.
Further, if the first SRS and the second SRS of the overlapping symbol are identical in time domain characteristic, the priority is determined according to the purpose.
For example, the periodic SRS for perceived overlapping symbols is prioritized over periodic SRS transmission for uplink channel information acquisition of a non-codebook uplink transmission scheme. For another example, when the semi-persistent SRS acquired based on the uplink channel information of the codebook uplink transmission scheme overlaps with the semi-persistent SRS for perception in the time domain, the terminal should not transmit the semi-persistent SRS for perception, which is configured in the same symbol, and only transmit the semi-persistent SRS acquired based on the uplink channel information of the codebook uplink transmission scheme.
In one possible example, the prioritization may be further refined such that the aperiodic SRS for uplink channel information acquisition based on the codebook uplink transmission scheme has a higher priority than the semi-persistent SRS for sensing, the semi-persistent SRS for downlink channel information acquisition based on SRS antenna switching has a higher priority than the periodic SRS for sensing, and the periodic SRS for sensing has a higher priority than the periodic SRS for uplink beam management.
In some embodiments, the prioritization between the first SRS and the second SRS may be specified by a protocol. Or may be configured by the network. Or may be predetermined by the base station and the terminal.
In one implementation, in step S102, if the first SRS collides with a physical uplink control channel (Physical Uplink Control Channel, abbreviated PUCCH), the first SRS is transmitted or discarded according to the priority ordering between the first SRS and the PUCCH.
Specifically, collision of the first SRS and the PUCCH may specifically mean that the first SRS and the PUCCH overlap on time domain resources, for example, the first SRS and the PUCCH overlap on at least one symbol under the same carrier condition.
Further, according to the priority order between the first SRS and the PUCCH, if the priority of the first SRS is highest, the first SRS is sent in a time unit where collision occurs or the first SRS is directly sent, and the PUCCH is directly discarded, otherwise, the first SRS is discarded in a time unit where collision occurs or the first SRS is directly discarded, and the PUCCH is sent.
In some embodiments, the prioritization between the first SRS and the PUCCH may be determined according to the time domain characteristics of the first SRS and the data carried by the PUCCH.
Specifically, the priority of the semi-persistent and periodic first SRS is lower than the priority of the PUCCH.
For example, for overlapping of the first SRS and PUCCH on one carrier condition, the first SRS of the overlapping symbol is discarded for semi-persistent or periodic first SRS.
Further, the priority of the aperiodic first SRS is higher than the priority of the PUCCH carrying periodic or semi-persistent data.
For example, for the first SRS and PUCCH overlapping on one carrier condition, for the aperiodic first SRS, if the PUCCH carries semi-persistent or periodic channel state Information (CSI for short), or the PUCCH carries semi-persistent or periodic Layer 1signal to interference plus noise ratio (Layer 1Signal to Interference and Noise Ratio, L1-SINR for short) or Layer 1reference signal received power (Layer 1Reference Signal Received Power, L1-RSRP for short), the data carried by the PUCCH is discarded at the overlapping symbols.
In a typical application scenario, the prioritization between the first SRS and PUCCH may follow the discard rule of the existing protocol:
1) When the semi-persistent and periodic SRS is configured in the same symbol as the PUCCH carrying only the CSI report, or when the semi-persistent and periodic SRS is configured in the same symbol as the PUCCH carrying only the L1-RSRP report, the terminal should not transmit the first SRS.
2) When the semi-persistent first SRS or the periodic first SRS or the aperiodic first SRS is triggered, the terminal shall not transmit the first SRS when the same symbol as the PUCCH carrying the hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, abbreviated as HARQ) ACKnowledgement (ACK) and/or the scheduling request (Scheduling Request, SR) is transmitted.
3) In the case where the first SRS is not transmitted due to overlapping with the PUCCH, only the first SRS symbol overlapping with the PUCCH is discarded.
4) After the aperiodic first SRS is triggered, the terminal should not transmit PUCCH when the same symbol as PUCCH carrying a semi-persistent/periodic CSI report or carrying only a semi-persistent/periodic L1-RSRP report.
In some embodiments, the priority ranking between the first SRS and the PUCCH may be determined according to the purpose of the first SRS, without focusing on the priority of the perceived traffic or on the bearer content of the PUCCH.
For example, the priority of the first SRS may be defined to be higher than the priority of the PUCCH.
In other words, in step S102, the first SRS is always transmitted in the superimposed symbol or directly transmitted, and the data carried by the PUCCH is not considered regardless of the time domain characteristics of the first SRS.
For another example, it may be defined that the priority of the first SRS is lower than the priority of the PUCCH.
In other words, in step S102, the first SRS is always discarded in the overlapping symbol or is directly discarded, and the data carried by the PUCCH is not considered regardless of the priority of the sensing service associated with the first SRS.
In some embodiments, the prioritization between the first SRS and the PUCCH may be determined according to the priority of the traffic (e.g., perceived traffic) associated with the first SRS and the priority of the data carried by the PUCCH.
In particular, perceived traffic may also be prioritized like Quality of service (Qos) of a sidelink (sidelink). For example, traffic may be split into high priority aware traffic and low priority aware traffic with a threshold. The first SRS may be associated with a service.
Further, the data carried by the PUCCH has a priority ordering, and the corresponding PUCCH also has priority. The low priority PUCCH may be, for example, a PUCCH carrying semi-persistent or periodic CSI reports, L1-SINR, and L1-RSRP. PUCCHs carrying other data may be classified as high priority PUCCHs.
For example, a prioritization may be defined of high priority perceived traffic > high priority PUCCH > low priority perceived traffic > low priority PUCCH. In practice, other ranks may be defined as desired.
In one implementation, in step S102, if the first SRS collides with a Physical Uplink Shared Channel (PUSCH) SHARED CHANNEL, the first SRS is transmitted or discarded according to the priority ranking between the first SRS and the PUSCH.
Specifically, collision between the first SRS and the PUSCH may specifically mean that the first SRS and the 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.
Further, according to the priority order between the first SRS and the PUSCH, if the priority of the first SRS is highest, the first SRS is sent in a time unit where collision occurs, otherwise, the first SRS is discarded in the time unit where collision occurs, and data carried by the PUSCH is sent.
In some embodiments, the prioritization between the first SRS and PUSCH may be determined according to a PUSCH-associated communication scenario.
In particular, the communication scenarios may include eMBB (Enhanced Mobile Broadband ), uRLLC (Ultra-Reliable and Low-Latency Communications), and mMTC (MASSIVE MACHINE TYPE Communications, large-scale machine Communications). Wherein eMBB scenarios are designed for high-capacity, high-rate broadband data services, aimed at providing a faster, more stable wireless broadband connection experience for users. eMBB is mainly characterized in that high-speed data transmission is provided, and the method is suitable for high-capacity data transmission such as high-definition video, virtual reality, cloud game and downloading. The uRLLC scenario is to meet the demands for low latency and high reliability communications, such as real-time control, medical and autopilot applications. uRLLC are characterized by providing extremely low latency and high reliability to ensure reliability and stability for real-time and critical applications. mMTC is used for supporting large-scale Internet of things equipment connection and meeting the connection requirements of mass equipment, such as intelligent home, intelligent city, industrial automation and other applications. mMTC are mainly characterized by connectivity, low power consumption and low cost of large-scale equipment.
In a typical application scenario, the prioritization between the first SRS and PUSCH may follow the discard rule of the existing protocol:
1) If the PUSCH associated with eMBB scene is scheduled simultaneously with the first SRS in the same slot, only the first SRS is supported to be scheduled after the PUSCH associated with eMBB scene.
2) If the PUSCH associated with uRLLC scene overlaps with the first SRS, the first SRS is discarded with symbol granularity (symbol-wise).
In some embodiments, the prioritization between the first SRS and the PUSCH may be determined according to its use.
For example, the priority of the first SRS may be defined to be higher than the priority of the PUSCH.
In other words, in step S102, the first SRS is always transmitted in the superimposed symbol, and the PUSCH-related communication scenario is not considered, regardless of the time domain characteristics of the first SRS.
For another example, the priority of the first SRS may be defined to be lower than the priority of PUSCH.
In other words, in step S102, the first SRS is always discarded in the overlapping symbol or is directly discarded, and the PUSCH-related communication scenario is not considered regardless of the time domain characteristics of the first SRS.
In one implementation, prior to step S101, the present embodiment may further include the step of receiving second information including a plurality of candidate first resource sets, the resources in the first resource sets being used for transmission of the first SRS.
Specifically, the network may configure the terminal with a plurality of candidate first resource sets through the second information in advance, and then activate or trigger one of the candidate first resource sets through the first information for the terminal to transmit the first SRS.
In some embodiments, the time-domain granularity of the first SRS for sensing may be longer than that of the second SRS conventionally used for other purposes, and may depend on the accuracy requirement of the velocity (velocity) or angle (angle).
For example, the length of at least one of the first set of resources may be greater than the length of a single slot, such as greater than 14 OFDM symbols. The longer the number of symbols of the resources for the perceived first SRS, the higher the perceived accuracy, and accordingly the resources in the first set of resources may be allowed to be configured across multiple slots.
For another example, resources in at least one of the first set of resources are configured in units of symbols. For example, the resource may be configured to start with the first symbol of the first slot and end with the fifth symbol of the second slot.
As another example, multiple time domain granularity mixing configurations are possible, e.g., one resource may include x slots and y symbols.
In one embodiment, the resources of the at least one first set of resources may be periodically retransmitted.
Specifically, a new repetition factor (repetitionfactor) may be added to the second information to indicate the number of repeated transmissions of the resources in the first set of resources.
For example, the length of the resources in the first set of resources may be configured to be 6 OFDM symbols and 4 periodic transmissions repeated.
In some embodiments, the first set of resources may be configured to be dedicated to the first SRS. For example, a separate configuration of SRS for perception may be given in the second information, like SRS for positioning purposes.
In some embodiments, the first set of resources may be a set of resources whose purpose is configured to be perceived. For example, a new type (i.e., a perceived type) may be added in the use of the existing SRS resource set. Thus, the SRS resource set in RRC signaling may be configured as a first resource set for awareness, and also as a second resource set for other purposes. The second set of resources is used to transmit a second SRS.
In some embodiments, the second information may be carried by higher layer signaling, e.g., by RRC signaling.
In one implementation, in step 102, if it is determined to transmit the first SRS, the first SRS may be further transmitted according to a default beam direction (default beam).
Specifically, when the network does not configure the 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.
In some embodiments, the default beam direction may be the beam direction of the last successfully perceived object. For example, in an intrusion detection scenario, the beam direction of the object may be successfully perceived with the last time (last) as the default beam direction for the current first SRS. Intrusion detection may be, for example, airspace detection, such as detection of an intrusion of a drone into a private home.
In some embodiments, the default beam direction may be determined from a configured listening range.
Specifically, the network may configure a listening range X for the terminal in advance. The listening range X may be configured to the terminal, for example, by pre-definition, by higher layer signaling, or by dynamic signaling. Wherein X may be angle information or location information, which may be configured by a network side through higher layer signaling or determined by a predefined form.
Further, the terminal may determine the coverage angle of each resource in the configured first set of resources at its own discretion. That is, the beam width that needs to be covered when the first SRS is transmitted on each resource. Thereby, the degree of freedom of the terminal beam implementation can be given. For example, assuming x=180 degrees, the first set of resources includes 6 resources, each resource may be swept 30 degrees on average.
For another example, assuming that x=180 degrees, the terminal may scan 180 degrees per resource when transmitting the first SRS.
For another example, assuming that x=180 degrees, the first resource set includes 9 resources, the terminal may determine that one of the resources scans 100 degrees when transmitting the first SRS, leaving 8 resources to scan 10 degrees each.
In a variation, the default beam may also be preconfigured by the network, which facilitates interference management for the network.
Therefore, when the SRS is configured to perform a sensing function and collide with other data transmission, a proper collision processing mechanism can be provided through the embodiment, so that the terminal is ensured to correctly perform data transmission, and the communication reliability is improved. Further, whether the first SRS is discarded or not is determined according to a preset priority rule, so that priority transmission of high-priority data is guaranteed. The data may include SRS, data carried by PUCCH, and data carried by PUSCH.
