Description
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a medium for updating and indicating a path loss reference signal.
Background
PL RS (Path Loss reference signal; PL: path Loss; RS: reference signal) is a channel Path Loss estimated when used to calculate uplink PUSCH (physical uplink shared channel ), PUCCH (physical uplink control channel, physical Uplink Control Channel), SRS (channel sounding reference signal, sounding Reference signals) transmission power. To ensure accuracy of the estimation, the path loss estimate needs to be obtained based on L3 (layer 3) filtering.
The PL RS determination method may be as follows:
the RRC (radio resource Control ) configures the mapping relation between SRI-PUSCH-powercontrol ID (SRI-PUSCH-power Control identifier; SRI: SRS resource indication, SRS resource indicator) and PL RS ID, then the MAC CE (media access Control unit; MAC: media access Control, media Access Control; CE: control Element) may update the mapping relation between SRI-PUSCH-powercontrol ID and PL RS ID (identifier), and finally the adopted SRI-PUSCH-powercontrol ID and the corresponding PL RS ID (e.g. SRI0 corresponds to SRI-PUSCH-powercontrol id=0 and its associated PL RS 0) are determined according to the SRI in the DCI.
For PUCCH, RRC configures the mapping relation between PUCCH-SpanishRelationInfoId (PUCCH-spatial relation information identification) and PL RS ID, and then determines the PL RS ID according to the activated PUCCH-SpanishRelationInfoId in MAC CE.
For AP/SP-SRS set (AP/SP-SRS set; AP aperiodic, SP: semi-persistent): the RRC configures N PL RS IDs, and the MAC CE activates 1 of the PL RSIDs.
The prior art has the following defects: the existing PL RS maintenance mode has large MAC CE overhead.

Detailed Description
The inventors noted during the course of the invention that:
the RRC configures a maximum of 64 PL RSs, but considering that the estimation of the path loss requires the UE (User Equipment) to perform L3 filtering, the UE capability requirement is relatively high, so the current standard specifies that although the RRC can configure a maximum of 64 PL RSs, the UE only needs to maintain a maximum of 4 PL RSs at the same time, and these 4 include the sum of PL RSs for PUSCH, PUCCH, SRS. And the standard specifies that the UE does not need to maintain PL RSs with MAC CEs inactive. In order to ensure that the number of PL RSs maintained by the UE is not more than 4, the base station is required to ensure that the total number of all PL RSs activated by the current MAC CE is not more than 4 each time the PL RSs are updated by the MAC CE.
Fig. 1 is a MAC CE maintenance schematic, as shown, at the first moment, the MAC CE has activated 4 PL RSs for PUSCH, PUCCH, SRS. The UE needs to maintain L3 filtering of these 4 PL RSs. At the second time, if the PLRS 0 of SRS set for Codebook (SRS set for codebook) is to be updated to PL RS 4, the number of PL RS that the UE needs to track exceeds 4, and the UE may not maintain the deactivated PL RS 0 as specified. However, PL RS 0 is currently also PL RS of PUCCH 0 and PUCCH 1. Therefore, in order to ensure that the total number of PL RSs maintained by the UE is not more than 4, the PL RSs can only be updated simultaneously by reasonable scheduling of the base station, for example, using MAC CEs simultaneously being SRS set forCodebook, PUCCH 0 and PUSCH, so as to ensure that the total number of PLRSs activated by the MAC CEs is not more than 4, and the MAC CE overhead is very large. That is, every time PL RS is updated, all PL RSs that have been activated by the current MAC CE need to be considered, if the number of PL RSs that are activated after PL RS are updated exceeds 4, a certain PL RS, for example PL RS 0, needs to be deactivated, and all SRS, PUCCH, PUSCH associated with PL RS 0 are updated in the MAC CE once through the MAC CE, so that the number of PL RSs maintained by the UE is guaranteed to be no more than 4.
There are up to 4 types of SRS set (Codebook), non-Codebook (Beam management), antenna switching (antenna switching)), up to 56 PUCCH resources, and PL RS is required for 1 PUSCH. 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 been designed. If PL RSs of a plurality of SRS, PUCCH, PUSCH are updated simultaneously, MAC CE overhead is very large.
Based on this, the embodiment of the present invention provides a scheme for PL RS update and PL RS update indication, which is used to reduce MAC CE overhead, and the following description of the specific embodiment of the present invention is given with reference to the accompanying drawings.
In the description, the transmission procedure will be described from the implementation of the terminal and the base station, respectively, and the base station side will describe the transmission procedure, so that the description does not mean that the two must be implemented cooperatively or separately, in fact, when the UE and the base station are implemented separately, they solve the problems of the UE side and the base station side, respectively, and when the UE and the base station are used in combination, better technical effects are obtained.
In a PL RS updating method at a terminal side, a terminal determines a plurality of reference signals and/or channels; and updating the PL RSs of the plurality of reference signals and/or channels according to the indication.
In the method for updating the indication PL RS at 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 PL RSs of the plurality of reference signals and/or channels, comprising:
the method comprises the steps that firstly, a terminal determines a plurality of reference signals and/or channels with the same path loss reference signal identifier PL RS ID; when the PL RS of at least one of the reference signals and/or channels is updated, the PL RS of the reference signals and/or channels having the same PLRS ID is updated identically; or,
mode two, PL RS of one or more reference signals and/or channels are updated according to the indication.
The following description will be given separately.
Fig. 2 is a schematic flow chart of an implementation of a PL RS update method at a terminal side, which may include:
Fig. 3 is a schematic flow chart of an implementation of a method for updating an indication PL RS at a base station side, which may include:
Specifically, for example, PL RSs with the same PL RS ID may be updated in a collective manner, in which a collection may be formed by using reference signals and/or channels with the same PL RS ID, and when the PL RS ID of any one reference signal or channel in the collection is updated, all the reference signals and/or PL RS IDs of the channels in the collection are updated together.
The terminal side judges according to the PL RS ID, and forms a set of all the reference signals and/or channels (including SRS resource set, PUCCH resource 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 PL RS IDs of channels of the set are updated together.
The following is an example.
SRS, PUCCH, PUSCH (e.g. SRS set 0, PUCCH 0, PUSCH) with PL RS id=0 forms 1 set a, and when the MAC CE updates the PL RS for PUSCH, there is no need to additionally transmit the PL RS for MAC CE update SRS set 0 and PUCCH 0, and PL RSs of all reference signals and/or channels in set a to which the PUSCH belongs are updated simultaneously to PL RS id=1.
In practice, the reference signal and/or channel is one or a combination of the following signals or channels:
SRS、PUCCH、PUSCH。
in practice, when the base station indicates PL RS of a plurality of reference signals and/or channels through MAC CE, the terminal updates according to the indication.
Accordingly, the base station side may be:
in practice, the base station instructs the terminal to update the PL RS of the reference signal and/or channel with the same PL RS ID identically through the MAC CE.
In implementation, the method may further include:
according to the indication of the RRC or the MAC CE, it is determined whether to update the PL RS of other multiple reference signals and/or channels having the same PL RS ID when the PL RS is updated by the MAC CE.
Accordingly, the base station side may be:
the terminal is instructed by the RRC or MAC CE, and when the PL RS is updated according to the MAC CE, whether the PL RS of other multiple reference signals and/or channels having the same PL RS ID is updated.
Specifically, a signaling may be added, for example, adding 1bit to RRC or MAC CE, to indicate whether the PL RS updated by MAC CE represents that all the PL RSs of SRS, PUCCH, PUSCH in a set are updated together.
For example: 0 means that only the SRS, PUCCH, or PUSCH indicated by the MAC CE is updated, and 1 means that the PL RSs of SRS, PUCCH, PUSCH, which are the same as other PL RSs, are updated together at the same time, so as to increase configuration flexibility.
In implementation, the method may further include:
the priority of PL RS updating the indicated reference signal or channel is higher than the priority of PL RS indication updating the reference signal or channel having the same PL RS ID at the same time.
Specifically, the priority may be specified: the PL RS updating only the current reference signal or channel has a higher priority than the PL RS updating one set.
The embodiment of the invention also provides another updating and updating indicating scheme, and the scheme is described below.
