Description

Path loss reference signal update and indication update method, device and medium

technical field

The present invention relates to the technical field of wireless communication, in particular to a path loss reference signal update and indication update method, device and medium.

Background technique

PL RS (path loss reference signal; PL: path loss, Path Loss; RS: reference signal, reference signal) is used to calculate the uplink PUSCH (physical uplink shared channel, Physical Uplink Shared Channel), PUCCH (physical uplink control channel, Physical Uplink Control Channel), SRS (Sounding Reference signals) transmit power, estimate the path loss of the channel. In order to ensure the accuracy of the estimation, the path loss estimation needs to be obtained based on L3 (layer 3) filtering.

PL RS can be determined as follows:

RRC (Radio Resource Control, Radio Resource Control) configures the mapping relationship between SRI-PUSCH-PowerControlId (SRI-PUSCH-power control identifier; SRI: SRS resource indicator, SRS resource indicator) and PL RS ID, and then MAC CE (media access Control control unit; MAC: media access control, Media Access Control; CE: control unit, Control Element) can update the mapping relationship between SRI-PUSCH-PowerControlId and PL RS ID (identification), and finally determine the adopted one according to the SRI in DCI SRI-PUSCH-PowerControlId and corresponding PL RSID, for example, SRI0 corresponds to SRI-PUSCH-PowerControlId=0 and its associated PL RS 0.

For PUCCH, RRC configures the mapping relationship between PUCCH-SpatialRelationInfoId (PUCCH-SpatialRelationInfoId) and PL RS ID, and then determines the PLRS ID according to the activated PUCCH-SpatialRelationInfoId in MAC CE.

For AP/SP-SRS set (AP/SP-SRS set; AP aperiodic, aperiodic, SP: semi-persistent, semi-persistent): RRC configures N PL RS IDs, and MAC CE activates one of the PL RS IDs.

The disadvantage of the existing technology is that: the existing PL RS maintenance mode MAC CE overhead is relatively large.

Detailed ways

The inventor noticed during the invention that:

RRC can configure a maximum of 64 PL RSs, but considering the estimation of path loss requires UE (User Equipment, User Equipment) to perform L3 filtering, which requires relatively high UE capabilities. Therefore, the current standard stipulates that although RRC can configure up to 64 PL RSs, UE Only need to maintain up to 4 PL RS at the same time, these 4 include the sum of PLRS for PUSCH, PUCCH, SRS. And the standard stipulates that the UE does not need to maintain the PL RS that the MAC CE is not activated. In order to ensure that the number of PL RS maintained by the UE does not exceed 4, the base station is required to update the PL RS with the MAC CE each time to ensure that the total number of all PL RS activated by the current MAC CE does not exceed 4.

Figure 1 is a schematic diagram of MAC CE maintenance. As shown in the figure, at the first moment, the MAC CE is PUSCH, PUCCH, and SRS has activated four PL RS. The UE needs to maintain the L3 filtering of these 4 PL RSs. At the second moment, if you want to update the PLRS 0 of the SRS setfor Codebook (the SRS set used for the codebook) to PL RS 4, it will cause the number of PL RSs that the UE needs to track (track) to exceed 4, according to the regulations The UE may no longer maintain the deactivated PL RS 0. However, PL RS 0 is currently still the PL RS of PUCCH 0 and PUCCH 1. Therefore, in order to ensure that the total number of PL RS maintained by the UE does not exceed 4, it can only be reasonably scheduled by the base station, such as using MAC CE to simultaneously update PL RS for SRS set for Codebook, PUCCH 0 and PUSCH to ensure the total number of PL RS activated by MAC CE No more than 4, MAC CE overhead is very large. That is to say, every time you update the PL RS, you need to consider all the PL RSs that have been activated by the current MAC CE. If the number of activated PL RSs exceeds 4 after updating the PL RS, you need to deactivate a certain PL RS, for example PL RS 0, update all SRS, PUCCH, and PUSCH associated with PLRS 0 in MAC CE through MAC CE to ensure that the number of PL RS maintained by the UE does not exceed 4.

Uplink has up to 4 types of SRS set (Codebook (codebook), Non-codebook (non-codebook), Beammanagement (beam management), Antenna switching (antenna switching)), up to 56 PUCCH resource (resource), 1 PUSCH needs PL RS. Updating PL RS for each PUCCH resource requires MAC CE 24bits. The MAC CE needed to update PL RS for SRS and PUSCH has not yet been designed. If multiple SRSs, PUCCHs, and PL RSs of PUSCHs are updated at the same time, the MAC CE overhead is very large.

Based on this, the embodiment of the present invention provides a solution for updating PL RS and indicating PL RS updating, which is used to reduce MAC CE overhead. The specific implementation manner of the present invention will be described below with reference to the accompanying drawings.

In the description process, the description will be made from the implementation of the terminal and the base station side respectively. The base station side will explain the transmission process. This way of description does not mean that the two must be implemented together or must be implemented separately. In fact, when the UE When it is implemented separately from the base station, it also solves the problems on the UE side and the base station side respectively, and when the two are used in combination, better technical effects will be obtained.

In the PL RS update method on the terminal side, the terminal determines multiple reference signals and/or channels; and updates the PL RS of the multiple reference signals and/or channels according to the instructions.

In the instruction PL RS update method on the base station side, the base station instructs the terminal to update the PL RS of one or more reference signals and/or channels.

Updating the PL RS of the multiple reference signals and/or channels includes the following methods:

Method 1. The terminal determines that the path loss reference signal identifies multiple reference signals and/or channels with the same PL RS ID; when the PL RS of at least one of the reference signals and/or channels is updated, the reference signals and/or channels with the same PL RS ID the channel's PL RS for the same update; or,

Method 2: Update the PL RS of one or more reference signals and/or channels according to the instruction.

Each will be described below.

Fig. 2 is a schematic diagram of the implementation process of the PL RS update method one on the terminal side, as shown in the figure, may include:

Step 201, the terminal determines multiple reference signals and/or channels with the same path loss reference signal identifier PL RS ID;

Step 202, when the PL RS of at least one reference signal and/or channel is updated, the PL RS of the reference signal and/or channel with the same PL RS ID is updated in the same way.

Fig. 3 is a schematic diagram of an implementation flow diagram of an instruction PL RS update method on the base station side, as shown in the figure, may include:

Step 301, the base station determines multiple reference signals and/or channels with the same PL RS ID;

Step 302, when the base station instructs at least one of the reference signals and/or channel PL RS to update, the reference signal and/or channel PL RS with the same PLRS ID perform the same update.

Specifically, for example, a collection method can be used to update PL RSs with the same PL RS ID. In this method, reference signals and/or channels with the same PL RS ID can be formed into a set. When any reference signal or channel in the set When the PL RS ID is updated, the PL RS IDs of all reference signals and/or channels of the set are updated together.

The terminal side judges according to the PL RS ID, and forms a set of all reference signals and/or channels (including SRS resource sets, PUCCH resources and PUSCH) with the same PL RS ID.

When the MAC CE updates the PL RSID for a certain SRS resource set or PUCCH resource or PUSCH, the terminal side judges whether the SRS resource set or PUCCH resource or PUSCH belongs to a certain set, and if so, all reference signals and/or or the PL RS ID of the channel is updated together.

The following examples are used to illustrate.

SRS, PUCCH, and PUSCH with PL RS ID = 0 (such as SRS set 0, PUCCH 0, PUSCH) form a set A. When MAC CE updates PL RS for PUSCH, there is no need to send MAC CE to update SRS set 0 and PUCCH 0, the PL RS of all reference signals and/or channels in the set A to which the PUSCH belongs is also updated to PL RS ID=1 at the same time.

In implementation, the reference signal and/or channel is one or a combination of the following signals or channels:

SRS, PUCCH, PUSCH.

In implementation, when the base station indicates multiple reference signals and/or PL RS of the channel through the MAC CE, the terminal updates according to the indication.

Correspondingly, the base station side can be:

In the implementation, the base station instructs the terminal to perform the same update on the PL RS of the reference signal and/or channel with the same PL RS ID through the MAC CE.

In implementation, it may also include:

According to the instruction of RRC or MAC CE, it is determined whether to update the PL RS of other multiple reference signals and/or channels with the same PL RS ID when the PL RS is updated through the MAC CE.

Correspondingly, the base station side can be:

Instruct the terminal through RRC or MAC CE, when updating the PL RS according to the MAC CE, whether to update the PL RS of other multiple reference signals and/or channels with the same PL RS ID.

Specifically, a signaling can be added, for example, 1 bit is added in RRC or MAC CE to indicate whether the PL RS updated by MAC CE represents updating all SRS, PUCCH, and PUSCH PL RSs in a set.

For example: 0 indicates that only the SRS or PUCCH or PUSCH indicated by the MAC CE can be updated, and 1 indicates that the PL RS of the same SRS, PUCCH, and PUSCH of other PL RSs are updated together at the same time to increase configuration flexibility.

In implementation, it may also include:

Updating the PL RS of the indicated reference signal or channel has a higher priority than simultaneously updating the PL RS indication of a reference signal or channel with the same PL RS ID.

Specifically, the priority can be specified: the priority of only updating the PL RS of the current reference signal or channel is higher than that of updating a set of PL RS.

Another solution for updating and indicating updating is also provided in the embodiment of the present invention, which will be described below.

Figure 4 is a schematic diagram of the implementation process of the second PL RS update method on the terminal side, as shown in the figure, may include:

Step 401, the terminal determines multiple reference signals and/or channels;

Step 402, update the PL RS of one or more reference signals and/or channels according to the instruction.

Fig. 5 is a schematic diagram of the implementation process of the instruction PL RS update method two on the base station side, as shown in the figure, may include:

Step 501, the base station determines multiple reference signals and/or channels to be updated;

Step 502, the base station instructs to update the PL RS of one or more reference signals and/or channels.

In implementation, the reference signal and/or channel is one or a combination of the following signals or channels:

SRS, PUCCH, PUSCH.

In the implementation, the base station instructs to update the PL RS of multiple reference signals and/or channels through the MAC CE.

Specifically, FIG. 6 is a schematic diagram of one MAC field information. As shown in the figure, one MAC CE field can be used to simultaneously indicate multiple SRSs, PUCCHs, PUSCHs and one PL RS.

Based on the same inventive concept, the embodiments of the present invention also provide a base station, a terminal, and a computer-readable storage medium.
