Description

Configuration method, configuration device, network side equipment and computer readable storage medium
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a configuration method, an apparatus, a network side device, and a computer-readable storage medium.
Background
The existing 5G NR (new air interface) PDSCH (physical downlink shared channel) EPRE (per resource element) power allocation and demodulation process is as follows: firstly informing the power of a terminal SSB (synchronization signal block) through an MIB (master information block) message, then informing a terminal Pc _ ss (offset value based on the SSB) through an RRC (radio resource control) message, acquiring a CSI-RS EPRE (channel state information reference signal) based on the power relation between a CSI-RS (indication channel state information reference signal) and the SSB, then informing the power relation between the terminal CSI-RS and a PDSCH through the Pc (offset value) to acquire PDSCH EPRE, and finally acquiring the power relation between the terminal CSI-RS and the PDSCH through the Pc (offset value)
Figure BDA0002108256250000011
And acquiring the relation between the DMRS (demodulation reference signal) and the PDSCH to acquire the demodulation DMRS EPRE for correctly demodulating the PDSCH signal.
However, in the existing protocol, the relation between the CSI-RS and the PDSCH is not known. The position of PDSCH is divided into two EPRE with CSI-RS time slot and without CSI-RS time slot. While the current protocol does not express explicitly, Pc refers to whether the CSI-RS is related to the simultaneous slot PDSCH EPRE or the other slots PDSCH EPRE. If the protocol is not specified, PDSCH EPRE power at two positions is the same by default, and PDSCH EPRE linkage power at two positions can cause the system performance to be greatly reduced. If the CSI-RS RE (resource block) and the PDSCH RE are in the same symbol, and the CSI-RS performs Power boosting to the CSI-RS Power boosting with full bandwidth, PDSCH EPRE in the same time slot needs to be reduced, and the Power of PDSCH EPRE at the two positions is consistent, which results in non-maximum Power transmission data of the whole system and waste of system resources. If the power of PDSCH EPRE for non-co-slots is not changed, the sum of the power of the CSI-RS and the co-slot PDSCH (i.e., the slot power) may exceed the standard.
As can be seen from the above, the 5G NR downlink power allocation scheme in the prior art cannot guarantee the PDSCH performance of the 5G NR downlink traffic channel.

step 11: and under the condition that power reduction needs to be carried out on each resource element RE of the PDSCH, configuring the REs of the PDSCH in the same time slot with the CSI-RS as the non-scheduled PDSCH REs or zero-power CSI-RS REs.
In the configuration method provided by the embodiment of the invention, under the condition that the power reduction needs to be carried out on each resource element RE of a Physical Downlink Shared Channel (PDSCH), the REs of the PDSCH in the same time slot with a channel state information reference signal (CSI-RS) are configured to be unscheduled PDSCH REs or zero-power CSI-RS REs; the method can ensure that the PDSCH EPRE Power of symbols different from the CSI-RS is not reduced basically on the premise that PDSCH EPRE of symbols different from the CSI-RS and PDSCH EPRE of symbols same as the CSI-RS are the same after the CSI-RS Power Boosting, reduce the influence of the CSI-RS Power Boosting on the PDSCH EPRE Power, ensure that the 5G NR PDSCH performance is not reduced basically, and well solve the problem that the 5G NR downlink Power distribution scheme in the prior art cannot ensure the 5G NR downlink service channel PDSCH performance.

The CSI-RS full bandwidth refers to all 273 Physical Resource Blocks (PRBs) configured for the CSI-RS, and the CSI-RS sub bandwidth refers to less than all 273 PRBs configured for the CSI-RS.
Specifically, the configuring the REs of the PDSCH in the same time slot as the CSI-RS is not scheduled PDSCH REs or zero-power CSI-RS REs, including: obtaining the resource allocation number according to the preset power upper limit value, the total power of the CSI-RS after the power is lifted and the total number of downlink bandwidths capable of not scheduling resources; and configuring the PDSCH REs with the number corresponding to the CSI-RS time slot as the non-scheduled PDSCH REs or the zero-power CSI-RS REs according to the resource configuration number.

In the embodiment of the present invention, configuring the REs of the PDSCH in the same time slot as the CSI-RS as the unscheduled PDSCH REs, includes: and configuring the REs of the PDSCH in the same time slot with the CSI-RS as the unscheduled PDSCH REs at a multimedia access MAC layer.

The configuration method provided by the embodiment of the present invention is further described below.
In order to solve the above technical problem, in order to ensure that the performance of the PDSCH of the downlink traffic channel is not substantially reduced after CSI-RS Power Boosting, an embodiment of the present invention provides a configuration method, which may specifically be a method for allocating 5G NR downlink Power: the influence of CSI-RS Power Boosting on PDSCH EPRE Power is reduced by configuring base station scheduling PDSCH resources (configuring base station resource scheduling positions) or Zero Power CSI-RS reference signal resources.
Specifically, as shown in fig. 2, the scheme for "confirming that power reduction needs to be performed for each RE of the PDSCH" in the embodiment of the present invention includes:
step 21: confirming whether the scheduling resource is a CSI-RS full bandwidth or a CSI-RS sub-bandwidth, if so, entering a step 22, and if so, entering a step 25;
step 22: judging whether the CSI-RS is Power boosting, if so, entering a step 23, and if not, entering a step 24;
step 23: PDSCH EPRE power is unchanged;
step 24: PDSCH EPRE power reduction, confirming that power reduction is required for each RE of PDSCH;
step 25: judging whether the CSI-RS Power + unscheduled PDSCH EPRE Power < Max Power is true, if so, entering step 27, and if not, entering step 26;
step 26: PDSCH EPRE power reduction scheduled, confirming that power reduction is required for each RE of PDSCH;
step 27: the scheduled PDSCH EPRE power is unchanged.
The power variation of CSI-RS analyzed from fig. 2 can cause power variation of PSDCH EPRE, and PDSCH EPRE power related to symbol different from CSI-RS can also vary, resulting in unreasonable reduction of PDSCH traffic channel performance due to power reduction;
in order to ensure that PDSCH EPRE power of symbols different from CSI-RS is not changed by CSI-RS power change, thereby causing downlink performance degradation, the following measures may be adopted in the embodiment of the present invention:
firstly, the network side equipment configures and schedules PDSCH RE resources in an MAC layer, wherein PDSCH RE Power which does not send data can be used for CSI-RS RE Power Power Boosting. Under the premise that the total Power is not changed, in order to ensure that the CSI-RS PB (Power boost) does not affect the Power of PDSCH EPRE, the number N of PDSCH REs that are not scheduled under the same symbol as the CSI-RS is (Max Power-ALL Power (None Zero Power CSI-RS Power Boosting))/(Max Power/N)PRB DL) If the total number of downlink bandwidths N of the resources can be not scheduledPRB DLAnd if the power of the PDSCH RE is less than or equal to N, the power of the PDSCH RE is unchanged, otherwise, the PDSCH RE of the downlink traffic channel is still reduced, so that the performance of the downlink traffic channel is reduced, but compared with a scene that the PDSCH RE is not configured and is not scheduled, the performance is still improved by a large amount.
Wherein Max Power represents the maximum Power, i.e. the preset Power upper limit value; ALL Power (None Zero Power CSI-RS Power Boosting) represents the total Power after CSI-RS Power ramp-up.
And secondly, configuring PDSCH downlink resources RE into Zero Power CSI-RS reference signals through RRC signaling by the network side equipment in an RRC layer, wherein the PDSCH downlink resources RE can be used for neighbor cell signal measurement, and the Power of the PDSCH downlink resources RE can be used for Power Boosting of non-Zero Power CSI-RS. Is configured under the same symbol as CSI-RSSetting the number N of PDSCH REs of the Zero Power CSI-RS as (Max Power-ALL Power (None Zero Power CSI-RS Power Boosting))/(Max Power/N)PRB DL)。
Wherein Max Power represents the maximum Power, i.e. the preset Power upper limit value; ALL Power (None Zero Power CSI-RS Power Boosting) represents the total Power of the CSI-RS after Power is raised; n is a radical ofPRB DLIndicating the total number of downlink bandwidths that may (may) not schedule resources.
As can be seen from the above, in the scheme provided in the embodiment of the present invention, by configuring REs in the same Symbol as CSI-RS as PDSCH REs not to be scheduled or Zero Power CSI-RS, it is ensured that Power of PDSCH EPRE in symbols different from CSI-RS is not reduced on the premise that PDSCH EPRE in symbols different from CSI-RS is the same as PDSCH EPRE in symbols same as CSI-RS, and performance of PDSCH in 5G NR downlink traffic channel is ensured.
In summary, the scheme provided by the embodiment of the invention can ensure that the power change of the CSI-RS does not affect the PDSCH EPRE power as much as possible no matter whether the CSI-RS has the same time slot as PDSCH EPRE, thereby ensuring the performance of the downlink traffic channel PDSCH; specifically, the method can be as follows:
(1) in order to ensure that the Power of PDSCH EPRE is not influenced as much as possible by the change of the Power of the CSI-RS, PDSCH EPRE which has the same time slot with the CSI-RS is configured not to be scheduled, and the Power is used for Power Boosting of the CSI-RS;
(2) in order to ensure that the Power of PDSCH EPRE is not influenced as much as possible by the change of the Power of the CSI-RS, PDSCH EPRE which is in the same time slot with the CSI-RS is configured into Zero Power CSI-RS, and the Power is used for non Zero Power CSI-RS Power Boosting.
