[0255] The embodiments of the present invention are further explained below in conjunction with specific scenarios.

[0256] Ultra-wide bandwidth high frequency bands (i.e. millimeter wave communications) have become an important direction for the future development of mobile communications, attracting the attention of academia and industry around the world. In particular, with increasingly congested spectrum resources and a large number of physical network accesses, the advantages of millimeter waves have become increasingly attractive, and many standard organizations, such as IEEE and 3GPP, have begun to carry out corresponding standardization work. For example, in the 3GPP standard group, high frequency band communications will become an important innovation point of 5G New Radio Access Technology (New RAT) with its significant advantage of large bandwidth.

[0257] In an optional implementation, during the antenna weight (also known as precoding, beam) training process, the high-band transmitter sends a training pilot, and the receiver receives the channel and performs channel estimation. Then, the high-band receiver needs to feed back channel state information to the training transmitter, so that the transmitter and receiver can find multiple groups of transmitter and receiver antenna weight pairs required for multi-channel data transmission from the optional transmitter and receiver antenna weight pairs, thereby improving the overall spectrum efficiency.

[0258] In the embodiment of the present invention, power parameters, phase parameters and port numbers are flexibly supported for QCL, thereby avoiding the problems of repeated resource configuration, a large amount of RRC signaling expenses and limited downlink coverage.

[0259] Through the embodiments of the present invention, by supporting QCL-oriented power, phase and port number configuration, the resource utilization efficiency and configuration flexibility in the millimeter wave system are significantly improved, which not only effectively saves the cost of RRC resource reconfiguration signaling, but also improves the diversity gain of downlink transmission and ensures effective downlink coverage by supporting multiple antenna panels to serve one same antenna port.

[0324] Here, h2 is the DL-Link2 channel response measured for TRS#b, a2 is the offset parameter for the target channel (PDSCH / PDCCH) transmission relative to TRS#b, and n is the noise.

[0325] Among them, the parameters of h1 and h2 are known to the UE, but a1 and a2 need to be informed by the base station.

[0326] After the UE obtains the a1 and a2 parameters, the UE can receive the data through a receiving algorithm, such as a RAKE receiver, y=(a1*h1)H*y1+(a2*h2)H*y2.

[0327] Fig. 9Another downlink transmission of multiple QCL status indications in an optional embodiment of the present invention is as follows: Fig. 9 As shown, two QCL states are associated (or applied) to a reference signal TRS#m, one of which includes {QCL Type-A, SS / PBCH#a} and {QCL Type-D, CSI-RS for BM#1}, and the other QCL state includes {QCL Type-A, SS / PBCH#b} and {QCL Type-D, CSI-RS for BM#2}. When the two reference signals in a QCL state are different, the first information (e.g., power parameter or phase parameter) is associated with the reference signal corresponding to QCL Type C, i.e., SS / PBCH#a and SS / PBCH#b in the figure.

[0328] In an optional implementation, in order to support multi-beam simultaneous transmission of PDCCH or PDSCH, the reference signal TRS#m can be used as a QCL reference reference signal and configured to a DMRS port or port group of PDCCH or PDSCH.

[0329] Fig.10 is a QCL state under a phase and power parameter configuration of an optional embodiment of the present invention, such as Fig.10 As shown, for a QCL state, two QCL sets are included, namely QCL set-A and QCL set-B, wherein each QCL set includes two QCL Types and corresponding reference RSs. In addition, the QCL state also includes a phase parameter and a power parameter, wherein the phase parameter provides the relative phase difference between the reference signals of the two QCL parameter sets, and the power parameter provides the relative power difference of the reference signals between the two QCL sets.

[0330] The following explains the signaling design of the embodiment of the present invention, including trigger state, ReportConfig and PTRS parameter update:

[0331] In an optional implementation, the first information is carried via MAC-CE signaling or RRC signaling.

[0332] In an optional implementation, the first information is applied to a reference signal associated with a trigger state; or,

[0333] In an optional implementation, the first information is used to report a reference signal associated with the configuration.

[0334] In addition, in an optional implementation, the MAC-CE is also used to activate the QCL state associated with the PDSCH.

[0335] In addition, in an optional embodiment, the first information includes the number of phase tracking reference signal ports. In order to combat the influence of strong phase noise (for example, in millimeter wave communication (also known as Frequency range 2, or Above 6 GHz) system), the base station needs to configure the phase tracking reference signal for each base station's TRP or panel respectively. Considering the MAC-CE signaling, which is used to integrate multiple QCL states into a combined state (or, a new state), at this time, the number of ports of the phase tracking reference signal needs to be provided by the MAC-CE signaling.

[0336] In an optional embodiment, according to the first information, the port of the phase tracking reference signal and the DMRS port are determined, or the correspondence between the port of the phase tracking reference signal and the DMRS port group is determined, for example, corresponding in sequence from small to large. For example, the phase tracking reference signal corresponds to port 0 and port 1, and the DMRS port groups are CDM group 2 and CDM group 3, and then, the phase tracking reference signal port 0 is associated with CDM group 2, and the phase tracking reference signal port 1 is associated with CDM group 3.

[0337] Fig.11 A non-periodic CSI trigger state configuration framework in the related art. In the existing non-periodic CSI trigger state configuration, multiple CSI-RS resources are combined into a CSI-RS resource set, and the one CSI-RS resource set is associated with a CSI resource setting (also called CSI-RS resource config). One or more CSI resource settings can be associated with a CSI reportingconfig, wherein, when multiple CSI resource settings are associated, the multiple CSI resource settings can be used for channel measurement (channel measurement) or interference measurement (interference measurement), respectively. In the CSI reporting config, it is additionally necessary to provide the QCL state of each non-periodic CSI-RS for the association. Among them, from PDSCH RE (resource element) to CSI-RS (in Fig.11In the figure, the power offset (called Pc) of non-zero-power (NZP)-CSI-RS) and the power offset (PSS) from NZP CSI-RS RE to SSS (Second Synchronization Signal) RE are configured on the CSI-RS resource.

[0338] In an optional implementation, while flexibly adjusting the QCL state of the non-periodic CSI-RS, the base station does not have the right to adjust the power parameters of the non-periodic CSI-RS. In this way, it is difficult for the base station to flexibly adjust the number of antenna groups serving the transmission (as the number of service antenna panels increases, the transmission power will be further enhanced, but the number of different beams used to simultaneously serve multiple users will be restricted).

[0339] Fig.12 It is a phase and power parameter configuration framework for a trigger state in an optional embodiment of the present invention, such as Fig.12 As shown, the power offset Pc from PDSCH RE to NZP-CSI-RS RE and the power offset PSS from NZP-CSI-RS RE to SSS RE can be configured in the CSI-RS trigger state. In this way, the base station can provide corresponding power parameter information while flexibly configuring the QCL state of the non-periodic CSI-RS.

[0340] In an optional implementation, when multiple CSI-RS resource settings are included, it is necessary to set power parameters for each CSI-RS resource under the multiple CSI-RS resource settings separately, or configure a set of power parameters for each CSI-RS resource setting (including a power offset Pc from PDSCH RE to NZP-CSI-RS RE, or a power offset PSS from NZP-CSI-RS RE to SSS RE), and the set of power parameters is applied to all CSI-RS resources under the CSIresource setting.

[0341] Fig.13 This is a phase and power parameter configuration framework for CSI report configuration in an optional embodiment of the present invention, such as Fig.13As shown, the power offset Pc from PDSCH RE to NZP-CSI-RS RE, and the power offset PSS from NZP-CSI-RS RE to SSS RE can be configured in the CSI report configuration (i.e., different CSI resource settings have independent power parameters). Furthermore, for non-periodic CSI report configurations, the corresponding CSI-RS from multiple CSI resource settings need to have the same QCL state.

[0342] Fig.14 This is a process of MAC-CE activating power parameters in an optional embodiment of the present invention, such as Fig.14 As shown, multiple non-periodic CSI triggering states are configured in RRC signaling, and one or more of the triggering states are activated by MAC-CE signaling. The MAC-CE signaling provides the Pc parameter of each CSI-RS resource under the report configuration in each activated triggering state.

[0343] In an optional implementation, the Power offset may be provided for the determination of L1-SINR / RSRP (CMR+IMR).

[0344] The first communication node (eg, UE) determines a value of SINR or RSRP according to the first type of information;

[0345] Then, the first communication node reports the SINR or RSRP value to the second communication node (eg, base station).

[0346] In an optional implementation, the value of SINR or RSRP is determined according to the power parameter in the first type of information.

[0347] In an optional implementation, the SINR or RSRP value is determined based on the measured SINR or RSRP value and the power parameter in the first type of information.

[0348] In an optional embodiment, the reference signal includes one or a combination of the following: a channel state information reference signal (CSI-RS) for channel measurement, and a channel state information reference signal (CSI-RS for IM) for interference measurement.

[0349] In an optional embodiment, the step associated with the signal to interference plus noise ratio reporting codeword is determined by at least one of the following parameters:

[0350] the type of reference signal associated with the signal to interference plus noise ratio,

[0351] The type of reporting associated with the signal to interference plus noise ratio.

[0352] The reference signal type includes at least one of the following:

[0353] A zero-power channel state information reference signal for interference measurement;

[0354] A non-zero power channel state information reference signal for interference measurement;

[0355] A zero-power channel state information reference signal for interference measurement, and a non-zero-power channel state information reference signal for interference measurement; or,

[0356] Reference signal used for channel measurement.

[0357] The reference signal used for channel measurement includes a synchronization signal or a channel state information reference signal.

[0358] The report types include group-based beam reporting and disenabled group-based beam reporting.

[0359] For example, the SINR report is based on a differential reporting mode, in which the maximum measured SINR value is reported using an absolute value, while other SINR values ​​are differential values ​​based on the maximum measured SINR value. The differential value is carried by, for example, 4 bits, so the step value corresponding to each adjacent codeword (for example, from 4'b0000 to 4'b0001) is related to the report configuration. Further, the step value is determined by the reference signal type of different SINR reports, for example, when the associated reference signal is only a reference signal for channel measurement (also known as channel measurement resource, CMR), the step of each adjacent codeword is 2dB, and when the associated reference signal is CMR and a non-zero-power channel state information reference signal for interference measurement (also known as Non-zero-power interference measurement resource, NZP-IMR), the step of each adjacent codeword is 0.5dB.
