Description

SRS transmission method, device and system

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to an SRS transmission method, device and system.

Background

Currently, in order to measure an uplink channel of a User Equipment (UE), a base station configures the UE in a cell to send a Sounding Reference Signal (SRS) on some specific time-frequency resources to probe the quality of the uplink channel. Generally, the number of users carried by SRS resources (resources occupied by SRS transmission) is large, and each UE can respectively occupy one sub-band with a smaller bandwidth to transmit the SRS, so as to ensure that more UEs can transmit the SRS on the same SRS resource.

However, when the sub-band bandwidth occupied by each UE for transmitting SRS is small, information of the uplink channel detected by the UEs is limited, which may affect measurement accuracy of the uplink channel, so that the UEs may transmit SRS at different time and different frequency domain positions (i.e. occupy different sub-bands) by using a frequency hopping method, so as to increase the SRS transmission bandwidth. Specifically, the UE may configure Radio Resource Control (RRC) parameters (e.g., SRS bandwidth configuration parameters (C)) according to higher layers _SRS ) And SRS subband number (B) _SRS ) Etc.), the hopping pattern is confirmed and then SRS hopping is performed based on the hopping pattern to completely cover a wider bandwidth.

However, when the UE performs SRS frequency hopping, the UE needs to complete all the determined frequency hopping patterns, that is, the UE needs to complete the detection of the configured frequency hopping bandwidth, and can complete the whole frequency hopping process, and some frequency hopping bandwidths do not need to be detected by the UE, and can also implement the measurement of the uplink channel of the UE, which may result in the waste of SRS resources.

The SRS transmission method, the device and the system provided by the embodiment of the invention can be applied to a communication system. The method and the device can be particularly applied to the communication system, and the UE transmits the SRS on the frequency hopping resource according to the SRS transmitting times and the initial resource position configured by the network equipment.

The embodiment of the invention can be applied to various communication systems, such as a 5G communication system, a future evolution system or other communication systems. A variety of application scenarios may be included, such as machine-to-machine (M2M), D2M, enhanced mobile broadband (eMBB), and ultra-reliable and low latency communications (urlllc). The specific method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

A UE is a device that provides voice and/or data connectivity to a user, a handheld device with wired/wireless connectivity, or other processing device connected to a wireless modem. A UE may communicate with one or more core network devices via a Radio Access Network (RAN). The UE may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, or a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, which exchanges languages and/or data with the RAN, for example, a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), and so on. A UE may also be referred to as a User Agent (User Agent) or a terminal device, etc. As an example, in the embodiment of the present invention, fig. 1 illustrates that the UE is a mobile phone.

The network device may be a base station. A base station is a device deployed in a RAN for providing wireless communication functions for UEs. The base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different radio access technologies, the names of devices with base station functionality may differ, for example, in third generation mobile communication (3G) networks, referred to as base stations (NodeB); in a Long Term Evolution (LTE) system, referred to as an evolved NodeB (eNB) or eNodeB; in fifth generation mobile communication (5G) networks, referred to as a gNB, and so on. As communication technology evolves, the name "base station" may change.

An SRS transmission method, an SRS transmission apparatus, and an SRS transmission system according to embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Based on the communication system shown in fig. 1, an embodiment of the present invention provides an SRS transmission method, which may include, as shown in fig. 2, steps 201 to 204 described below.

Step 201, the network device sends target information to the UE.

In an embodiment of the present invention, the target information includes at least one of the following items: the target times of sending the SRS by the UE and the target initial resource position of sending the SRS by the UE.

In the embodiment of the present invention, when the network device needs to measure an uplink channel of the UE, the network device may configure the UE in the cell to send the uplink SRS in a frequency hopping (frequency hopping) manner, so as to measure the channel quality of a Physical Uplink Shared Channel (PUSCH) of the UE. The network device may configure the number of times the UE transmits the SRS, the starting resource location, and the like, so that the UE may transmit the SRS according to the information configured by the network device. In the frequency hopping mode, the bandwidth for the UE to transmit the SRS sounding is small, but the UE may transmit the SRS at different frequency domain positions at different times, and after one SRS hopping period, a wide bandwidth may be completely covered.

Optionally, in the embodiment of the present invention, the target number is less than or equal to a total number, where the total number is the total number of times that the UE sends the SRS when the UE completes detection of all frequency hopping resources in the target frequency hopping resources.

Optionally, in this embodiment of the present invention, the total number of times may be configured by the network device, preconfigured by the network device, or agreed by a protocol.

It should be noted that the target frequency hopping resource may be understood as: the network device configures one complete frequency domain resource (sounding bandwidth) for the UE requiring UE sounding. The total number of times can be understood as: the UE detects the number of hopping frequencies required to complete a complete frequency domain resource.

Optionally, in this embodiment of the present invention, the target starting resource location is a resource location where the UE starts sending the SRS in the target frequency hopping resource.

Optionally, in the embodiment of the present invention, the position of the target starting resource is the same as the position of the first frequency hopping resource in the target frequency hopping resources; or, the target starting resource position is different from the position of the first frequency hopping resource in the target frequency hopping resources. That is, the network device may instruct the UE to start transmitting the SRS at the position of any one of the target frequency hopping resources.

Optionally, in the embodiment of the present invention, when the SRS transmission mode is the aperiodic transmission mode, the bandwidth of the frequency hopping resource occupied by the UE each time the SRS is transmitted is smaller than or greater than a first value, where the first value is a ratio of the total bandwidth of the target frequency hopping resource to the total number of times.

In the embodiment of the present invention, for an aperiodic transmission mode (aperiodic SRS resource), a network device may configure, to a UE, a bandwidth of a frequency hopping resource when the SRS is transmitted each time, that is, the bandwidth of the frequency hopping resource when the SRS is transmitted each time by the UE is allowed to be different from a first value, and at this time, a partial frequency hopping function may be enabled, that is, the UE may transmit the SRS on a partial frequency hopping resource in a target frequency hopping resource.

Step 202, the UE receives target information sent by the network device.

And 203, the UE transmits the SRS on the target frequency hopping resource according to the target information.

In the embodiment of the present invention, the target frequency hopping resource is a resource configured by a network device for a UE to transmit an SRS.

Optionally, in this embodiment of the present invention, the network device may send a first parameter to the UE (where the first parameter is used to indicate the UE to send the frequency hopping resource of the SRS), so that after receiving the first parameter, the UE may determine the target frequency hopping resource according to the first parameter.

Optionally, in this embodiment of the present invention, the network device may configure the first parameter to the UE through a higher layer signaling (for example, an RRC signaling).

Optionally, in an embodiment of the present invention, the first parameter may include at least one of: SRS Bandwidth configuration parameter C _SRS SRS sub-band number B _SRS Frequency hopping bandwidth index b _hop And SRS frequency domain position index n _RRC And so on.

It should be noted that, for specific descriptions of each parameter in the first parameters, reference may be made to descriptions in the related art, which are not repeated herein.

Optionally, in the embodiment of the present invention, after receiving the target information, the UE may directly send the SRS on a part of the frequency hopping resources in the target frequency hopping resources according to the target information.

Optionally, in the embodiment of the present invention, the step 203 may be specifically implemented by the following step 203 a.

And 203a, under the condition that a preset condition is met, the UE transmits the SRS on the target frequency hopping resource according to the target information.

In an embodiment of the present invention, the preset condition includes at least one of the following: receiving third indication information of the network equipment, wherein the SRS transmission mode is a periodic transmission mode and the SRS transmission mode is a semi-continuous transmission mode; the third indication information indicates that the UE is allowed to transmit the SRS based on the target information.

It can be understood that, in this way, the UE transmits the SRS on part of the target hopping resources according to the target information under the instruction of the network device, the periodic transmission mode or the semi-persistent transmission mode.

Optionally, in this embodiment of the present invention, the network device may send the third indication information to the UE through the MAC CE and/or the DCI, so as to activate a partial frequency hopping function of the UE.

Optionally, in this embodiment of the present invention, the target information includes a target frequency. Referring to fig. 2, as shown in fig. 3, the step 203 can be specifically realized by the step 203b described below.

Step 203b, the UE starts to transmit the SRS from the first frequency hopping resource in the target frequency hopping resource, and sequentially transmits the SRS from each frequency hopping resource in the target frequency hopping resource until the number of SRS transmission times is greater than or equal to the target number of times, and then stops transmitting the SRS.

It can be appreciated that in this manner, the UE may transmit the SRS on the first K (K ═ target number of times) of the target hopping resources.

Optionally, in this embodiment of the present invention, when the target information includes the target number of times, the UE may start sending the SRS on the first frequency hopping resource (i.e., perform frequency hopping) according to a parameter (i.e., the first parameter) in the higher layer signaling and a frequency hopping formula agreed by a protocol, and stop sending the SRS until the number of times of sending the SRS (i.e., the number of times of frequency hopping) reaches the target number of times.

Illustratively, as shown in FIG. 4, it is assumed that higher layer signaling configures C _SRS ＝14，B _SRS ＝1，b _hop ＝0，n _RRC 0; the period of SRS resource is 2, the target number is 3, Ns is 4, and R is 1. The UE may determine, according to parameters configured by the high layer signaling, that a complete sounding bandwidth is 52 PRBs (illustrated by two filling regions in fig. 4), that is, a target frequency hopping resource is 52 PRBs, a frequency hopping bandwidth (i.e., a bandwidth of a frequency hopping resource occupied when sending an SRS) is 4 PRBs each time, a frequency hopping number required for sounding a complete sounding bandwidth is 13 times (i.e., a total number of times, 13 filling regions corresponding to a complete sounding bandwidth in fig. 4 indicate that the total number of times is 13 times), a frequency hopping pattern at this time is shown in fig. 4, and the UE may sequentially perform a first frequency hopping resource (the first frequency hopping resource and n number of frequency hopping resources) in the target frequency hopping resource (the first frequency hopping resource and n number of frequency hopping resource are indicated by the UE) _RRC Corresponding to 0), the SRS is transmitted on the second and third hopping resources (the three hopping resources are indicated by black filled regions in fig. 4), that is, the number of times the SRS is transmitted is three, and the SRS is not transmitted on the time-frequency domain resource limited by the target number of times in the target hopping resource (that is, the hopping resource except the hopping resource when the SRS is transmitted in the target hopping resource, and the filled region except the black filled region in 13 filled regions corresponding to one complete sounding bandwidth in fig. 4); and the UE can continue to follow the target time configured by the network equipment in the next SRS frequency hopping periodAnd (3) transmitting the SRS on the corresponding frequency hopping resource (namely, the number of times of transmitting the SRS is three).

In the embodiment of the invention, the UE can stop sending the SRS when the number of times of sending the SRS reaches the target number of times according to the target number of times configured by the network equipment, but does not directly send the SRS on all frequency hopping resources in the target frequency hopping resources, namely, the whole frequency hopping process is finished without completely detecting a complete frequency hopping bandwidth configured by the network equipment, so that the waste of the SRS resources is avoided, and the energy consumption of the UE is saved.

Optionally, in this embodiment of the present invention, when the target information includes a target starting resource position, the UE may start sending the SRS from the target starting resource position in the target frequency hopping resource, and send the SRS on each frequency hopping resource in the target frequency hopping resource in sequence, until a complete sounding bandwidth (that is, a last frequency hopping resource in the target frequency hopping resource) is sounded, the sending of the SRS is stopped.

Optionally, in this embodiment of the present invention, the target information includes a target number and a target starting resource location. Referring to fig. 2, as shown in fig. 5, the step 203 can be specifically realized by the step 203c described below.

Step 203c, the UE starts to transmit SRS from the target starting resource position in the target frequency hopping resource, and sequentially transmits SRS on each frequency hopping resource in the target frequency hopping resource, and stops transmitting SRS until the number of SRS transmissions is greater than or equal to the target number of times.

It can be appreciated that in this manner, the UE may transmit the SRS on K (K is a target number) hopping resources starting from a target starting resource position in the target hopping resource, i.e., the UE may not transmit the SRS on the hopping resource before the target starting resource position in the target hopping resource.

Optionally, in this embodiment of the present invention, when the target information includes the target number of times and the target starting resource location, the UE may start sending the SRS from the target starting resource location (i.e., perform frequency hopping) according to a parameter (i.e., the first parameter) in the higher layer signaling and a frequency hopping formula agreed by a protocol, and stop sending the SRS until the number of times of sending the SRS (i.e., the number of frequency hopping) reaches the target number of times.

Illustratively, as shown in FIG. 6, it is assumed that higher layer signaling configures C _SRS ＝14，B _SRS ＝1，b _hop ＝0，n _RRC 1; the period of SRS resource is 2, the target number of times is 3, the target starting resource location is 3, Ns is 4, and R is 1. The UE may determine that a complete sounding bandwidth is 52 PRBs (indicated by two padding regions in fig. 6) according to parameters configured by the high layer signaling, that is, the target frequency hopping resource is 52 PRBs, the frequency hopping bandwidth is 4 PRBs each time, and the frequency hopping number required for sounding a complete sounding bandwidth is 13 times (that is, the total number of times is 13 times for the 13 padding regions corresponding to a complete sounding bandwidth in fig. 6), where the frequency hopping pattern is as shown in fig. 6, the UE may start from the target resource location (a third frequency hopping resource in the target frequency hopping resource, the third frequency hopping resource and n are associated with the third frequency hopping resource, where the total number of times is 13 times for the 13 padding regions corresponding to the complete sounding bandwidth in fig. 6) _RRC Corresponding to 1), and sequentially transmitting the SRS on a fourth frequency hopping resource and a fifth frequency hopping resource (the three frequency hopping resources are indicated by a black filled region in fig. 6) in the target frequency hopping resource, that is, the number of times the SRS is transmitted is three, and the SRS is not transmitted on the time-frequency domain resource (i.e., the frequency hopping resource other than the frequency hopping resource when the SRS is transmitted in the target frequency hopping resource, and the filled region other than the black filled region in 13 filled regions corresponding to one complete sounding bandwidth in fig. 6) limited by the target number of times in the target frequency hopping resource, it can be seen that the SRS is not transmitted on the frequency hopping resource before the third frequency hopping resource; and, the UE may continue to transmit the SRS on the corresponding hopping resource according to the target number of times configured by the network device in the next SRS hopping period (that is, the SRS is transmitted from the third hopping resource three times).

In the embodiment of the invention, the UE can start sending the SRS from the target initial resource position according to the target frequency and the target initial resource position configured by the network equipment, and stops sending the SRS when the frequency of sending the SRS reaches the target frequency, but does not directly send the SRS on all frequency hopping resources in the target frequency hopping resources, namely, the whole frequency hopping process is finished without completely detecting a complete frequency hopping bandwidth configured by the network equipment, so that the waste of SRS resources is avoided, and the energy consumption of the UE is saved.

The following describes a method for aperiodic activation of a set of SRS resources and an effective window associated with the set of SRS resources by using a specific embodiment.

At present, when multiple SRS resource sets are configured, a network device may transmit multiple DCIs in the same time slot, and the multiple DCIs are respectively used to trigger different SRS resource sets, which may cause a Physical Downlink Control Channel (PDCCH) resource congestion. This problem is solved in the related art by a non-periodic activation method of the active window. However, in this method, if multiple SRS resources are activated in the same slot, only the SRS resource activated by the last DCI is transmitted. When two aperiodic SRS resource sets are configured for antenna switching of 1-way transmission and 4-way reception (1T 4R for short), and the two SRS resource sets are activated by one DCI at the same time, it may happen that two resource sets that should be originally transmitted in different slots are moved to the same slot by the existing aperiodic activation method based on an effective window, and if antenna switching cannot be completed in the same slot, antenna switching failure may be caused.

Based on the above problem, an embodiment of the present invention further provides a method for triggering an aperiodic SRS resource set, which is applied to a terminal device, and the method includes:

receiving downlink control information DCI; the DCI is used for activating an aperiodic Sounding Reference Signal (SRS) unit;

transmitting the SRS unit in at least one effective window corresponding to the activated SRS unit; the active window has at least one active time slot therein. One DCI may trigger at least one aperiodic SRS unit simultaneously, and each aperiodic SRS unit may include an SRS resource set or an SRS resource.

Optionally, in this embodiment of the present invention, the aperiodic set activation method for the UE using the valid window may be any one of the following methods:

sending DCI (Downlink control information) for triggering a plurality of aperiodic SRS resource sets to slot n, wherein n is the slot for sending a Physical Downlink Control Channel (PDCCH);

there is only one valid window; and under the condition that the aperiodic SRS unit comprises the SRS resource set, the position of the SRS resource set is determined according to the slot n, the nearest effective slot number and the offset in the SRS resource set. Wherein, the first SRS resource set: n + x1+ y1, y1 is less than or equal to z; second set of SRS resources: n + x2+ y2, y2 is less than or equal to z, y2 is more than y1(y2 is more than or equal to y 1); … …, respectively; the u-th SRS resource set: n + xu + yu, yu is less than or equal to z and yu is more than yu-1(yu is more than or equal to yu-1); x is a slot offset (offset) in the SRS resource set, y is a nearest valid slot, y is less than or equal to z, the unit of z is the slot, the slot number of a maximum valid window is represented (namely z represents the length of the valid window), zu represents the length of the valid window of the u-th SRS resource set, and xu represents the slot offset value of the u-th set;

slot offset starts with DCI; wherein, the first SRS resource set: n + x1+ y1, y1 is less than or equal to z 1; second set of SRS resources: n + x2+ y2, y2 is less than or equal to z2, y2 is more than y1(y2 is more than or equal to y 1); … …, respectively; the u-th SRS resource set: n + xu + yu, yu is less than or equal to zu and yu is more than yu-1(yu is more than or equal to yu-1);

the first slot offset takes the DCI as a starting point, and the last slot offset takes the former slot as a starting point; wherein, the first SRS resource set: n + x1+ y1, y1 is less than or equal to z 1; second set of SRS resources: n + x1+ x2+ y1+ y2, y2 is less than or equal to z 2; … …; the u-th SRS resource set: n + x1+. multidot. + xu + y1+. multidot. + yu, yu ≦ zu;

at least one effective window, wherein all the effective windows take the DCI + slot offset as a starting point;

at least one effective window is arranged, the first effective window takes the DCI + slot offset as a starting point, and the subsequent effective window takes the end position of the previous effective window as a starting point.

It should be noted that, the effective window has at least one effective slot, and a valid slot refers to an available symbol resource that can be used for completely transmitting all resources in a resource set and is owned in one slot in the effective window length slot, and the effective slot satisfies a minimum time interval requirement between DCI for activation and SRS resource for activation, satisfies a GP requirement for antenna switching, and includes a flexible resource that can be used for uplink transmission. Taking the DCI slot n as a starting point and containing slot n or not containing slot n; slots that contain the set or slots that do not contain the set are started from the set slot. The effective time slots are sequentially found by the plurality of SRS resource sets according to the sequence, the sequence of the plurality of SRS resource sets is carried out from small to large according to the slot offset value, the contained resource ID value, the slot offset value after the slot offset value or the size of the symbol position in the slot, and the like in the resource sets, namely the resource sets, the slot offset, the resource ID and the symbol positions in the resource are sequenced together.

Based on the embodiment of the invention, when the DCI activates the SRS unit, the SRS unit can complete transmission and reception in at least one effective window, so that the problem of PDCCH resource congestion or antenna switching failure caused by that at least one DCI simultaneously activates a plurality of SRS resources or a plurality of SRS resource sets in at least one SRS resource set can be solved, and the flexibility of activating the SRS unit by the DCI is realized.
