Description

Semi-static SRS resource indication method, semi-static SRS resource processing method, network side equipment and user terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a semi-static SRS resource indication method, a semi-static SRS resource processing method, a network side device, and a user terminal.

Background

The SRS (Sounding Reference Signal) is an uplink Reference Signal and is used by the base station to estimate uplink channel states of different frequencies. The Channel state obtained through Channel estimation may be used by the base station scheduler to schedule Uplink PUSCH (Physical Uplink Shared Channel) transmission of a certain terminal.

LTE (Long Term Evolution ) uplink defines two types of SRS transmission: periodic SRS transmission and aperiodic SRS transmission.

For signals having the same channel characteristics between different channels, it can be assumed that these signals are from the same transmission source. QCL (Quasi-co-location) configuration may include a variety of different Signal types, such as CSI-RS (Channel State Information-Reference Signal) or SSB (Synchronous Signal Block). The network side can configure its corresponding QCL signals for different beams. The network may change the operating beam of a UE (User Equipment) by changing the QCL configuration of the UE.

According to a current NR (New Radio, New air interface) conclusion, the semi-static SRS has a deactivation function, and can be activated by a MAC CE (Medium Access Control Element), but a specific activated or deactivated MAC CE format is not determined yet.

The semi-static SRS resource indication method and the semi-static SRS resource processing method of the present invention are described in detail below with reference to specific embodiments and the accompanying drawings:

example one

In this embodiment, the length of the MAC CE signaling sent by the network side device to the user terminal is not fixed.

The embodiment specifically comprises the following steps:

step 1: the network side device sends MAC CE signaling to the UE, and activates or deactivates a Semi-persistent SRS resource set of the UE, where a format of the MAC CE Header is shown in fig. 3.

Where R is a reserved bit and the initial value is 0. The LCID is used to indicate a MAC CE type, and here is used to indicate that a corresponding MAC CE activates or deactivates the MAC CE for an SP (Semi-persistent) SRS. The L field is used to indicate the length of the MAC CE.

For a certain SP SRS Resource Set, when the SP SRS Resource is deactivated, the SP SRS Resource is below 6GHz, the RRC configures a QCL relationship indication that does not carry the Resource Set in the MAC (for example, a 1bit indicates that a certain Resource does not need the QCL relationship indication), and the RRC configures a QCL relationship corresponding to the Resource Set (the default MAC CE does not carry the QCL relationship indication of the Resource any more), the MAC CE signaling sent by the network side device will not carry the QCL related information of the Resource Set. Taking as an example that all SP SRS Resource sets do not carry QCL related information, a corresponding MAC CE signaling format is shown in fig. 4.

Where the R field is a reserved bit, for example, its initial value may be set to 0. The A/D field (i.e. the first indication field) is used to indicate the activation/deactivation status of the SP SRS Resource Set. If the value is '1', activation is indicated, and if the value is '0', deactivation is indicated. The SP SRS Resource Set ID (semi-static SRS Resource Set identifier) represents an SP SRS Resource Set configuration identifier (index).

For a certain SP SRS Resource Set, if the condition that the Resource Set does not need to carry QCL related information is not satisfied, the MAC CE signaling sent by the network side device carries the QCL related information of the Resource Set. Taking the example that all SP SRS Resource sets carry QCL related information, the corresponding MAC CE signaling format is shown in fig. 5.

Where the R field is a reserved bit, for example, its initial value may be set to 0. The A/D field is used to indicate the activation or deactivation status of the SP SRS Resource Set. If the value is '1', activation is indicated, and if the value is '0', deactivation is indicated. The SP SRS Resource Set ID indicates an SP SRS Resource Set configuration identifier (index) configured by the network side device. The V field (i.e., the second indication field) is used to indicate the Resource type of the QCL relationship corresponding to the indicated SP SRS Resource Set. "00" indicates the SSB resource type. "01" is the SRS resource type. "10" indicates a CSI-RS resource type. "11" is reserved. The SSB/SRS/CSI-RS ID field (i.e., resource type identification) indicates an index of the corresponding resource type, the type of which is indicated by the V field.

Step 2: and the UE activates or deactivates the Semi-persistent SRS resource set according to the received MAC CE signaling.

And if a certain SP SRS Resource Set in the MAC CE signaling carries QCL related information, establishing the association relationship of the QCL of the corresponding Resource.

Example two

In this embodiment, the length of the MAC CE signaling sent by the network side device is fixed.

The embodiment specifically comprises the following steps:

step 1: the network side device sends MAC CE signaling to activate or deactivate the Semi-persistent SRS resource set of the UE, and the format of the MAC CE Header is shown in fig. 6.

Where R is a reserved bit and the initial value is 0. The LCID is used to indicate a MAC CE type, and here is used to indicate that the corresponding MAC CE activates or deactivates the MAC CE for SP SRS.

For a certain SP SRS Resource Set, when the SP SRS Resource is deactivated, the SP SRS Resource is at 6GHz, the RRC configures a QCL relationship indication that does not carry the Resource in the MAC (for example, 1bit indicates that the certain Resource does not need the QCL relationship indication), and the relationship of the QCL corresponding to the RRC configured Resource (the default MAC CE does not carry the QCL relationship indication of the Resource any more), the MAC CE signaling sent by the network side device will not carry the QCL related information of the Resource Set. Taking as an example that all SP SRS Resource sets do not carry QCL related information, the corresponding MAC CE signaling format is shown in fig. 7.

Wherein n is ceil (k/8). If k is not an integer multiple of 8, i.e. less than an integer number of bytes, the reserved bits are complemented. A. the_k(i.e., the first indication field) indicates the activation/deactivation status of the SP SRS Resource Set with index k. If the value is "1", activation is indicated. And if the value is 0, deactivation is indicated.

For a certain SP SRS Resource Set, if the condition that the Resource Set does not need to carry QCL related information is not satisfied, the MAC CE signaling sent by the network side device carries the QCL related information of the Resource Set. Taking the example that all SP SRS Resource sets carry QCL related information, the corresponding MAC CE signaling format is shown in fig. 8.

Where n is ceil (k/8), the reserved bits are supplemented if k is not an integer multiple of 8, i.e. less than an integer number of bytes. A. the_kAnd indicating the activation and deactivation state of SP SRS Resource Set with index of k. If the value is "1", activation is indicated. And if the value is 0, deactivation is indicated. The V field (i.e., the second indication field) is used to indicate the Resource type of the QCL relationship corresponding to the indicated SP SRS Resource Set. "00" indicates the SSB resource type. "01" is the SRS resource type. "10" indicates a CSI-RS resource type. "11" is reserved. The SSB/SRS Resource/CSI-RS ID field (i.e., Resource type identification) indicates an identification (index) of the corresponding Resource type, the type of which is indicated by the V field.

Example three:

in this embodiment, as shown in fig. 9, the MAC CE signaling subheader includes R, F, LCID and L, where R, F is a reserved bit and the initial value is 0. The L field is used to indicate the length of the MAC CE. LCID is a MAC CE type indication to indicate activation of a semi-static SRS resource set.

If the MAC CE carries the ID of a certain SP SRS resource set, it indicates that the resource set is activated, and if the MAC CE does not carry the ID of a certain SP SRS resource set, it indicates that the resource set is deactivated. As shown in fig. 10, a MAC CE signaling carries at least one Set of semi-static SRS Resource Set identifier (SP SRS Resource Set IDm), a second indication field (V field) and a Resource type identifier (SSB IDm/SRS Resource IDm/CSI-RS IDm), where the second indication field is used to indicate a Resource type of a QCL relationship corresponding to an activated semi-static SRS Resource Set, and the Resource type identifier is an identifier of the Resource type.

Example four:

in this embodiment, as shown in fig. 11, the MAC CE signaling subheader includes R and LCID, where R is a reserved bit and an initial value is 0. The LCID is an MAC CE type indication, and is used to indicate that a semi-static SRS resource set is deactivated and QCL information is not carried in the MAC CE signaling, that is, if a corresponding MAC CE carries an ID of a certain SP SRS resource set, it indicates that the resource set is deactivated.

The MAC CE signaling carries at least one semi-static SRS resource set identifier, and the semi-static SRS resource set identifier is used for indicating the deactivation state of a corresponding semi-static SRS resource set.

The fifth embodiment of the invention:

in this embodiment, as shown in fig. 12, the MAC CE signaling carries k first indication fields (a)_k) K QCL relationship identifiers (QCL relationship for SRS Resource ID), A_kAnd indicating the activation or deactivation state of the SP SRS resource set with index k, if the value is '1', indicating that the corresponding resource set is activated, and if the value is '0', indicating that the corresponding resource set is deactivated.

QCL relationship for SRS Resource ID is 1byte field, which indicates QCL association relationship corresponding to semi-static SRS Resource set. As shown in FIG. 13, the QCL relationship identification is 1byte in length, including R₁-R₈8 bits, when the mth bit of the QCL relationship identifier takes the value of "1", indicating that the corresponding semi-static SRS resource set is associated with the mth QCL relationship; and if the value is 0, the association of the QCL with index of m is not configured, and m is a positive integer not greater than 8. Wherein n is ceil (k/8), if k is not an integer multiple of 8, i.e. less than an integer number of bytes, the reserved bits are supplemented; when all bits of the QCL relation identifier take values of 0, indicating that no QCL relation is configured for the corresponding semi-static SRS resource set
