Detailed Description

So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

Technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The technical scheme of the embodiment of the application can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, or a 5G System.

For example, a communication system 100 applied in the embodiment of the present application may be as shown in fig. 1. The communication system 100 may include a network device 110, and the network device 110 may be a device communicating with a UE120 (or referred to as a communication terminal device, a terminal device). Network device 110 may provide communication coverage for a particular geographic area and may communicate with UEs located within that coverage area. Optionally, the Network device 110 may be a Base Transceiver Station (BTS) in a GSM system or a CDMA system, a Network device (NodeB, NB) in a WCDMA system, an evolved Node B (eNB, eNodeB) in an LTE system, or a wireless controller in a Cloud Radio Access Network (CRAN), or a Network device in a Mobile switching center, a relay Station, an Access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, a Network side device in a 5G Network, or a Network device in a Public Land Mobile Network (PLMN) for future evolution, or the like.

The communication system 100 also includes at least one UE120 located within the coverage area of the network device 110. "UE" as used herein includes, but is not limited to, connections via wireline, such as Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), Digital cable, direct cable connection; and/or another data connection/network; and/or via a Wireless interface, e.g., to a cellular Network, a Wireless Local Area Network (WLAN), a digital television Network such as a DVB-H Network, a satellite Network, an AM-FM broadcast transmitter; and/or another UE's device configured to receive/transmit communication signals; and/or Internet of Things (IoT) devices. A UE arranged to communicate over a radio interface may be referred to as a "wireless communication terminal device", a "wireless terminal device" or a "mobile terminal device".

Optionally, terminal-to-Device (D2D) communication may be performed between UEs 120.

It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

In the related art, in release 15, RRC configures an association between SRI-PUSCH-powercontrol Id (SRI PUSCH-power control identity) and PUSCH-pathlossrereferencers-Id (PUSCH-pathloss reference signal RS-identity). Also, a path loss RS (reference signal) for PUSCH transmission (codebook-based or non-codebook-based) scheduled by DCI format 0_1 is implicitly indicated by scheduling an SRI (srs resource indicator) indicated in DCI (DownLink Control Information). Then, the terminal device determines a path loss RS according to the value of PUSCH-pathlossReferenceRS-Id mapped to the SRI field in DCI format 0_ 1.

In this case, an RRC reconfiguration message is needed to update the mapping between sri-PUSCH-powercontrol Id and PUSCH-PathlossReferenceRS-Id.

The information content in the RRC reconfiguration message may be as follows:

further, in order to reduce the latency caused by the RRC reconfiguration message, RAN1 agrees (related protocol below) to introduce a new MAC CE to activate/update the value of PUSCH-PathlossReferenceRS-Id corresponding to sri-PUSCH-PowerControlId. RAN1 also agreed to extend maxNrofPUSCH-pathlossfrerencerss (i.e., the number of PUSCH pathloss reference signals) to 64, and 4 in release 15.

The PUSCH path loss update is related to a change in SRS spatial relationship if the usage of SRS resource sets is configured as "codebook-based or non-codebook-based". In this case, the PUSCH PL will be updated if the corresponding SRS spatial relationship changes, which means that the SRS spatial relationship and the PUSCH PL can be updated simultaneously by a single MAC CE.

The conclusion reached in RAN1 may be that a new MAC CE on AP-SRS/SP-SRS path loss RS activation/update, and AP SRS spatial activation/deactivation should be introduced.

The conclusions drawn about RAN1 can be as follows:

the path loss reference RS of the AP-SRS/SP-SRS may be activated/updated by the MAC CE.

The UE may be configured with multiple pathloss RSs via RRC and may be one of activated/updated for SRS resource sets via MAC CE. Relevant signalling details are provided in the RAN 2.

The higher layer filtered RSRP is reused for path loss measurement and applicable timing is defined after the MAC CE.

The filtered RSRP value of the previous path loss RS will be used before the application time, which is the next slot after the 5 th measurement sample, where the first measurement sample corresponds to the first instance, 3ms after sending ACK for the MAC CE.

This applies only to UEs supporting a RRC configurable number of path loss RSs greater than 4, and only to the case of PL RSs that do not track MAC CE activation. The UE is required to track the active PL RS only if the RRC configured PL RS is greater than 4.

Whether the UE is to update the filtered RSRP value of the previous PL RS 3ms after sending the ACK for the MAC CE depends on the UE. The LS is sent to RAN4 to solicit comments for this working hypothesis.

For UL beam management latency and overhead reduction, MAC CE based spatial relationship updating of aperiodic SRS for each resource level is supported.

In RAN1#97, the supported functionality of MAC CE based spatial relation update per resource level for aperiodic SRS is applicable for at least 3 supported usages, e.g. codebook based UL, non-codebook based UL, beam management.

In RAN1#98, the following working assumptions were confirmed after modification:

the functionality supported by the MAC CE based aperiodic SRS spatial relationship update is applicable to antenna switching at each SRS resource level. In the case of antenna switching, the UE may not expect to be configured with different spatial relationships within the same set.

Therefore, based on the foregoing analysis, if activation and deactivation for an AP/SP SRI (SRS spatial relationship info)) is to be implemented, and a pathloss RS ID of the SRS can be indicated, and at the same time, two or three MAC CEs may need to be designed to be implemented, so that multiple MAC CEs are generated, and signaling cannot be saved.

An embodiment of the present invention provides an information indication method, as shown in fig. 2, including:

step 21: the network equipment sends the MAC CE to the terminal equipment;

wherein the MAC CE is configured to indicate at least one of the following:

activation, update or deactivation of channel sounding reference signal Spatial relationship information (SRI, SRS Spatial relationship Info); the SRI is an Aperiodic (AP) SRI or a Semi-Static (SP) SRI.

Updating the path loss of a channel Sounding Reference Signal (SRS);

and updating the path loss of a Physical Uplink Shared Channel (PUSCH).

Correspondingly, the terminal device side also provides an information obtaining method, as shown in fig. 3, including:

step 31: the terminal equipment receives a Media Access Control (MAC) Control Element (CE) sent by the network equipment;

wherein the MAC CE is configured to indicate at least one of the following:

activating, updating or deactivating the channel detection reference signal spatial relation information SRI; the SRI is an aperiodic AP SRI or a semi-static SP SRI.

The present embodiment provides the above-mentioned solution, and can provide a new MAC CE format, where the MAC CE may be used for activating, updating, or deactivating an AP/SP SRI, and may indicate a pathloss RS ID of the SRS, and meanwhile, if a usage (usage) configured by the SRS is "codebook-based" or non-codebook ", the MAC CE may also indicate a pathloss RS ID of the PUSCH.

The following describes in detail the format of the MAC CE provided in this embodiment with reference to fig. 4.

First, the indication domain related to activation, update or deactivation of AP/SP SRI is explained:

the MAC CE comprises a first indication domain used for indicating activation, updating or deactivation of SRS resource sets;

wherein the SRS resource set is an AP SRS resource set or an SP SRS resource set.

Referring to fig. 4, the first indication field may be "a/D" in the MAC CE, and the length is 1 bit. Further, the first indication field, if set to a first value, may indicate that the SRS resource set is activated or updated, and if set to a second value, may indicate that the SRS resource set is deactivated. The first value may be "1", and the second value may be "0", or vice versa, which may be set according to actual situations.

Further, when the SRS resource set is the AP SRS resource set, if the first indication field is set to the first value, the AP SRS resource set may be considered to be updated, and the AP SRS resource set may be set to the second value, the AP SRS resource set may be considered to be deactivated;

when the SRS resource set is an SP SRS resource set, if the first indication field is a first value, the SP SRS resource set may be considered to be activated, and the value is set to a second value, which may be considered to be deactivated.

Regarding the differences between the aforementioned SP SRS and AP SRS, it can be: the method comprises the steps that an SP SRS resource set activates a spatial relationship corresponding to an SP SRS through an MAC CE, and then the spatial relationship corresponding to the SP SRS resource set is in an activated state, and corresponding information is continuously transmitted based on a corresponding period; the AP SRS resource set is different in that the MAC CE indicates to update the spatial relationship corresponding to the AP SRS resource set, but the MAC CE does not activate the spatial relationship corresponding to the AP SRS resource set, and further performs dynamic scheduling through other Information (e.g., DCI (DownLink Control Information)), and the SRS is sent after the DCI is activated.

The MAC CE further includes a second indication field for indicating a cell to which the SRS resource set belongs, and a third indication field for indicating a bandwidth portion BWP to which the SRS resource set belongs.

Referring to fig. 4, the second indication field may be "SRS Resource Set's Cell ID" (Cell ID to which SRS Resource Set belongs) in the MAC CE, and the third indication field may be "SRS Resource Set's BWP ID" (BWP ID to which SRS Resource Set belongs) in the MAC CE.

The length of the second indication field, that is, "SRS Resource Set's Cell ID", may be 5 bits, and may be used to indicate an identifier of a serving Cell, where the serving Cell corresponds to an activated, updated, or deactivated SRS Resource Set.

In addition, the content included in the second indication field may be determined in conjunction with the value of the indication field "C", for example, if the indication field "C" is set to a second value (e.g., 0), the second indication field may also be used to indicate a serving cell including all resources, where all resources are indicated by a "Resource (Resource) Identification (ID)" indication field.

The third indication field may be SRS Resource Set's BWP ID in fig. 4, and the length of the third indication field may be 2 bits.

Specifically, the third indication field indicates an Uplink (UL) BandWidth Part (BWP, BandWidth Part) as a code point of a DCI BandWidth Part indicator field specified in TS38.212[9 ]. Wherein, the activated/deactivated SP SRS resource set is contained.

In addition, if the C field (C indication field) is set to 0, the third indication field is used to indicate the identity of the BWP containing all the resources indicated by the Resource IDi field.

The C indicates the field (or C field), the length is 1 bit. This field indicates whether there is a resource serving cell ID field and a resource BWP ID field in the octet of the MAC CE. For example, if this field is set to 1, there are octets containing the resource serving cell ID field and the resource BWP ID field, otherwise there are no octets.

The MAC CE further includes a fourth indication field containing an identifier of the SRS resource set.

The fourth indication field may be an SRS Resource Set ID (SRS Resource Set ID) in fig. 4. The length of the field is 4 bits. The fourth indication field may indicate an identity of the SRS resource set; the identity may be the SRS-ResourceSetId identity specified in TS 38.331[5 ].

It should be noted that, although the fourth indication field does not distinguish whether the AP SRS or the SP SRS is targeted, the AP SRS or the SP SRS can be distinguished by IDs, for example, resources 1 to 3 are allocated to one AP SRS resource set, resources 4 to 10 are SP SRS resource sets, and different IDs are respectively used for distinguishing, which SRS resource set the MAC CE is targeted for is indicated by the fourth indication field, and the corresponding AP or SP SRS resource set is distinguished (or can be identified by the terminal device) based on the IDs.

The MAC CE includes M fifth indication fields for indicating identities of M resources in the SRS resource set; m is an integer of 1 or more.

For example, the M fifth indication fields may be Resource ID i in fig. 4, where i is greater than or equal to 0 and less than or equal to M-1.

Specifically, each fifth indication field, i.e. each Resource ID i, may have a length of 7 bits. This field contains an identifier of the resource used for spatial relationship derivation of SRS resource i. Resource ID0 refers to the first SRS resource in the set of resources, resource ID1 refers to the second resource, and so on.

The MAC CE further includes: m sixth indication fields; each of the M sixth indication fields is used to indicate a type of a resource in the corresponding fifth indication field;

wherein the type of the resource is one of: SSB, SRS, CSI-RS.

The sixth indication field may be Fi in fig. 4, and similarly, i is greater than or equal to 0 and less than or equal to M-1; it may be 1bit in length.

The sixth indication field may or may not be present and the manner of determining whether it is present may be determined based on the first indication field, i.e., the a/D. Specifically, the sixth indication field and the fifth indication field exist only when the MAC CE is used for SRS resource set activation, i.e., the a/D field is set to 1.

Each sixth indication field indicates a type of resource of the SRS resource used as a spatial relationship of the SRS resource.

Wherein F0 refers to the first SRS resource in the resource set, F1 refers to the second SRS resource, and so on.

The sixth indication field indicates that the NZP CSI-RS resource index is used when set to a first value (e.g., 1), and indicates that the SSB index or the SRS resource index is used when set to a second value (e.g., 0).

The fifth indication field, and the sixth indication field in combination, i.e. Fi and Resource ID i in combination, if Fi is set to 0 and the first bit of Resource ID i is set to 1, then the rest of Resource ID i contains the SSB-Index (specified in TS 38.331[5 ]). If Fi is set to 0 and the first bit of Resource ID i is set to 0, then the rest of Resource ID i contains the SRS-Resource Id (specified in TS 38.331[5 ]). This Resource ID i indicates that a field exists only when the MAC CE is used for SRS Resource set activation, i.e., the a/D field is set to 1.

The MAC CE further includes: m seventh indication domains used for indicating the identification of the cell where the SRI corresponding to the SRS resource is located, and M eighth indication domains used for indicating the identification of the BWP where the SRI corresponding to the SRS resource is located.

In conjunction with fig. 4, the seventh indication field may be Resource Serving Cell ID i in the MAC CE, which is 5 bits in length. The seventh indication field is used for indicating the serving cell identity, and the spatial relationship derivation resource of the SRS resource i is located in the serving cell.

The eighth indication field is Resource BWP ID i in fig. 4, and has a length of 2 bits. The indication field characterizes the resources used for spatial relationship derivation of SRS resource i, located on the UL BWP ID indicated by the indication field. The UL BWP serves as a code point (CodePoint) of a DCI BWP indication zone in TS38.212[9 ].

Based on the first to eighth indication fields, activation, update, and deactivation of the SRI can be achieved.

Specifically, the network device indicates activation, update, or deactivation of the set of SRS resources through the first indication field of the MAC CE. Under the condition of activating or updating the SRS resource set, indicating the corresponding SRS resource set through a fourth indication domain carried in the MAC CE; and indicating the cell and the BWP to which the SRS resource set belongs through a second indication domain and a third indication domain. And indicating the SRS resource identifier and the SRS resource type through the fifth indication domain and the sixth indication domain, and indicating the cell where the SRI corresponding to the SRS resource is located and the identifier of the BWP through the seventh indication domain and the eighth indication domain. Correspondingly, the terminal equipment analyzes the MAC CE and acquires an instruction for activating, updating or deactivating the SRS resource set from a first instruction domain of the MAC CE; under the condition of activating or updating the SRS resource set, determining the identification of the SRS resource set based on the fourth indication domain, and determining the cell and BWP to which the SRS resource set belongs based on the second indication domain and the third indication domain; determining M resources corresponding to the indication based on the M fifth indication domains, and determining each resource type according to the sixth indication domain; and determining the cell and the BWP in which the SRS corresponding to the resource is positioned according to the seventh indication field and the eighth indication field.

Wherein, the activating, updating or deactivating the SRS resource set is indicated by the first indication field, and may be:

when the SRS resource set is the AP SRS resource set, setting a first indication domain in the MAC CE to be a first value to indicate to update the AP SRS resource set, and if the first indication domain is set to be a second value, indicating to deactivate the AP SRS resource set;

and when the SRS resource set is the SP SRS resource set, the network equipment sets the first indication domain in the MAC CE to be a first value, then the SP SRS resource set is activated, the SP SRS resource set is set to be a second value, and the SP SRS resource set is deactivated.

In general, a network device activates or updates an SPS resource set via a MAC CE indication; and providing a specific cell corresponding to the SRI and the BWP through the indication corresponding to each resource, thereby controlling the activation, the update or the deactivation of the SRI.

Correspondingly, under the condition that the terminal equipment configures the SRS resource set as the AP SRS resource set, if the MAC CE is received and the first indication field indication is a first value, the AP SRS resource set is determined to be updated, and if not, the AP SRS resource set is deactivated; under the condition that the SRS resource set is configured to be the SP SRS resource set, if the MAC CE is received, wherein the indication of the first indication domain is a first value, the SP SRS resource set is determined to be activated, otherwise, the SP SRS resource set is deactivated.

On the basis of the foregoing, if the spatial relationship corresponding to the SRS is processed based on the foregoing, that is, the SRI is updated or activated, the corresponding SRS path loss RS is also updated accordingly. Next, referring to fig. 4, the SRS path loss reference signal RS is indicated, specifically as follows:

the MAC CE further includes: and a ninth indication field carrying an SRS path loss Reference Signal (RS).

As shown in fig. 4, the ninth indication field may be an SRS pathloss (path loss) RS field therein. The length may be 6 bits.

It should be noted that the granularity of the SRS pathloss RS is an SRS resource set or an SRS resource.

When the granularity of the SRS path loss RS is SRS resources, the MAC CE carries M ninth indicator fields of the SRS path loss RS corresponding to the M SRS resources.

For example, referring to fig. 5, only a part of the MAC CE is illustrated, and the rest is the same as fig. 4, and thus, the description will not be repeated. If there are M ninth indication fields, each ninth indication field is used to indicate a path loss RS corresponding to one SRS resource, and the ninth indication fields, that is, SRS pathloss RSs, are respectively denoted as SRS pathloss RS 0 to SRS pathloss RS M-1.

It should be noted that FIG. 5 is only an example, that is, the ninth indication field precedes the sixth indication field "Resource ID 0-M-1"; in another case, which is not shown in the figure, each of the ninth indication fields may precede a corresponding one of the sixth indication fields, that is, the ninth indication fields and the sixth indication fields are distributed at intervals. Of course, there may be other setting modes in the MAC CE, and this is not exhaustive.

On the side of the terminal device, the method further comprises: under the condition that the granularity of the SRS path loss RS is the SRS resource set, the terminal equipment acquires the path loss RS aiming at the SRS resource set from a ninth indication domain of the MAC CE; and under the condition that the granularity of the SRS path loss RS is the SRS resource, the terminal equipment respectively acquires the SRS path loss RS corresponding to the N SRS resources from M ninth indication domains of the MAC CE.

On the basis of the foregoing, the following further describes the indication of the PUSCH path loss RS with reference to fig. 4, specifically as follows:

the MAC CE further includes: a tenth indication field for indicating a PUSCH path loss RS.

And the MAC CE carries an eleventh indication domain for indicating whether the MAC CE carries the tenth indication domain.

Referring to fig. 4, the eleventh indication field may be a "PL" field in the MAC CE format, and has a length of 1 bit. For example, when PL is set to the first value (0), the MAC CE may be considered to omit the PUSCH pathLossReferenceRS-IF field, that is, it is not required to carry the tenth indication field; otherwise, the PUSCH pathLossReferenceRS-ID field should exist in the MAC CE (that is, the tenth indication field needs to be carried).

Still further, the manner of determining the indication value of the eleventh indication field may include:

and under the condition that the configured usage of the SRS is codebook-based or non-codebook-based, the tenth indication field is carried in the MAC CE.

Specifically, the method comprises the following steps: and under the condition that the usage configured by the SRS is based on a codebook or not, indicating that the MAC CE carries the tenth indication domain through an eleventh indication domain in the MAC CE.

When the granularity of the PUSCH path loss RS is an SRS resource set, the MAC CE carries 1 tenth indication domain;

and when the granularity of the PUSCH path loss RS is SRS resource, the MAC CE carries M tenth indication domains.

Wherein, the MAC CE carries M tenth indication fields, which may be as shown in fig. 4, and includes a plurality of "PUSCH paths RS". The MAC CE carries a pattern of 1 tenth indication field, which can be seen in fig. 6, where since one PUSCH path RS can be used for corresponding to one resource set, only one PUSCH path RS is needed to indicate path RSs of all resources.

In addition, as shown in fig. 4, other indication fields, such as the SUL and R fields shown in the figure, may also be included in the MAC CE format. Wherein, the SUL field is used for indicating whether the MAC CE is applied to the NUL carrier or the SUL carrier configuration. The field is set to 1 to indicate that it is applicable to the SUL carrier configuration and set to 0 to indicate that it is applicable to the NUL carrier configuration. R is used as a reserved bit, which is not limited in this embodiment.

It can be seen that, by adopting the above scheme, it is able to indicate by one MAC CE: the method comprises at least one of activation, updating or deactivation of channel sounding reference signal Spatial Relationship Information (SRI), updating of path loss of a channel Sounding Reference Signal (SRS) and updating of path loss of a Physical Uplink Shared Channel (PUSCH). In this way, the problem that one MAC CE is involved for each of the above contents, and thus a plurality of MAC CEs need to be transmitted to indicate the above contents, which results in no signaling saving can be avoided.

An embodiment of the present invention provides a network device, as shown in fig. 7, including:

a first communication unit 41 that transmits the MAC CE to the terminal device;

wherein the MAC CE is configured to indicate at least one of the following:

Updating the path loss of a channel Sounding Reference Signal (SRS);

and updating the path loss of a Physical Uplink Shared Channel (PUSCH).

Accordingly, the terminal device, as shown in fig. 8, includes:

a second communication unit 51, which receives a media access control MAC control element CE sent by the network device;

wherein the MAC CE is configured to indicate at least one of the following:

activating, updating or deactivating channel sounding reference signal Spatial Relationship Information (SRI); the SRI is an aperiodic AP SRI or a semi-static SP SRI.

wherein the type of the resource is one of: SSB, SRS, CSI-RS.

Specifically, the network device indicates activation, update, or deactivation of the set of SRS resources through the first indication field of the MAC CE. Under the condition of activating or updating the SRS resource set, indicating the corresponding SRS resource set through a fourth indication domain carried in the MAC CE; and indicating the cell and the BWP to which the SRS resource set belongs through a second indication domain and a third indication domain.
