Description

Quasi-co-location type processing method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for processing a quasi-co-location type.

Background

In a Long Term Evolution (Long Term Evolution, abbreviated as LTE)/Long Term Evolution-Advanced (Long Term Evolution-Advanced, abbreviated as LTE-a) system, when multipoint transmission is supported, since a base station for data transmission is transparent to a terminal and the base station for data transmission can be dynamically switched, the terminal cannot accurately know which base station the received data is transmitted by, and therefore, a definition and a notification signaling of a Quasi-Co-Location information indicator (Quasi-Co-Location indicator) are introduced.

The quasi-co-location Information indicator represents a Channel State Information Reference Signal (CSI-RS) for transmitting and notifying current data and a CSI-RS pilot for transmitting and notifying a user specific demodulation Reference Signal (Ue specific de-Modulation Reference Signal, DMRS for short), and is quasi-co-located, and both transmit large-scale characteristics of a Channel having approximately the same characteristics as the notified CSI-RS pilot, such as delay spread, Doppler shift, average delay, and the quasi-co-location can be understood as that the current data and the DMRS are approximately transmitted by the same base station.

After the terminal obtains the channel state information measurement pilot frequency CSI-RS or Cell specific Reference Signal (CRS) which is quasi-co-located with the DMRS, some statistical characteristic parameters of a channel between a base station and the terminal can be obtained in advance according to the pilot information during channel demodulation, so that the terminal can effectively utilize the statistical characteristic parameters to improve the estimation accuracy of demodulation pilot frequency, improve the performance of a receiver, effectively suppress noise, and apply the statistical characteristic parameters to different estimation algorithms and receiving algorithms.

It should be noted that the statistical channel characteristics can be accurately measured only by the pilot signals transmitted by the same base station, that is, the measurement of the statistical characteristic parameters is generally performed on the pilot signals transmitted by the same base station, such as CRI-RS or CRS. The terminal needs to know the DMRS and which CSI-RS or CRS is quasi co-located through the quasi co-location information indication.

In order to let the terminal know which base station transmits data, the base station configures 4 Physical Downlink Shared Channel Resource Element mapping (PDSCH RE mapping) parameters and quasi-co-location parameter sets through high-level signaling. And indicating one set of 4 physical downlink shared channel resource unit Mapping parameter sets and Quasi Co-Location parameter sets through a physical downlink shared channel resource unit Mapping and Quasi Co-Location indication (PQI) carried by a downlink control signaling. The terminal obtains the mapping parameter configuration and the quasi co-location parameter configuration of physical downlink shared Channel resource units in 4 physical downlink shared Channel resource unit mapping parameter sets and the quasi co-location parameter sets by receiving a high-level signaling, receives a downlink control signaling, and obtains the mapping parameter configuration and the quasi co-location parameter configuration of the physical downlink shared Channel resource units by a PQI indication set carried in the downlink control signaling, thereby obtaining the quasi co-location NZP CSI-RS and CRS parameter Information of the DMRS associated with the PDSCH.

In the 3GPP TS 36.213 standard, for transmission modes 1 to 9, the serving base station assumes that CRS ports 0 to 3, DMRS ports 7 to 14, and CRS-RS ports 15 to 30 are quasi co-located. For transmission mode 10, there are two types of quasi co-location types for the serving base station:

type A: the user assumes that antenna ports 0-3, 7-30 are quasi co-located, and they have large scale characteristics of approximately the same channel, such as delay spread, Doppler shift, average delay.

Type B: the user assumes that the ports 15-30 belonging to the CSI-RS resource configured by the higher layer parameters qcl-CSI-RS-ConfigNZPId-r11 are quasi co-located with the DMRS ports 7-14 associated with the PDSCH.

In addition, with the development of technology, the number of antennas of a base station is also increasing continuously, a protocol needs to be enhanced with the increase of the number of antennas, and two channel state information feedback categories are defined in Release13 version of Long Term Evolution-Advanced (LTE a) protocol: class a and Class B, respectively, wherein:

class A: a base station sends a CSI-RS, which is generally a non-precoded pilot, and a UE directly performs Channel measurement and CSI quantization based on the CSI-RS pilot to obtain Channel quality indication information (CQI), a Precoding Matrix Indicator (PMI), and a Rank Indicator (RI). The contents are fed back on a periodic and an aperiodic feedback mode.

Class B: the CSI-RS sent by the base station is generally a precoded pilot, and the UE may first perform selection of the precoded pilot, or resource set selection of the precoded pilot, or port group selection, and then perform quantization feedback of channel information based on the selected subset, including subset selection information and RI/PMI/CQI information corresponding to the selected CSI-RS measurement resource subset. The Class B can be configured with 1 set of CSI-RS resources, and the two situations are classified into Class B, K >1 and Class B according to the number of the CSI-RS resources, and K equals 1.

In the related CS/CB technology, standardization work was mainly set forth in the previous version of Release 13. In the quasi-co-location parameter configuration, only one piece of NZP CSI-RS parameter information is included, that is, the DMRS can only be quasi-co-located with K > -1 set of NZP CSI-RS from the same base station. The terminal considers that K >1 set of NZP CSI-RSs quasi-co-located with the DMRS are also quasi-co-located, and may be considered from the same transmission node, where K >1 mainly refers to the case of Class B, K >1, and for the case of Class B, K >1, the complexity of the user and the CSI-RS pilot overhead may be increased, because each transmission node is configured with K >1 set of NZP CSI-RSs, but K set of NZP CSI-RSs of each transmission node are used to measure the channel or measure the interference, the pilot overhead is relatively large, and the user also needs to measure multiple NZP CSI-RSs of K >1 set in multiple feedbacks respectively to complete the measurement of the interference and the channel, so the complexity is also relatively high. One way to save pilot overhead is to use K sets of NZP CSI-RS for ClassB, K >1, N sets of NZP CSI-RS to measure the channel, and other K-N sets of NZP CSI-RS to measure interference, where 1< ═ N < K. However, the prior art cannot support the situation that K sets of NZP CSI-RSs of Class B, K >1 come from different transmission nodes.

In view of the above problems in the related art, no effective solution has been found at present.

In order for the UE1 to be able to detect the received PDSCH, the TP1 needs to transmit a DMRS with the same precoding as the PDSCH, and the UE1 performs channel estimation using the DMRS and detects the PDSCH using the estimated channel. For the UE1 to perform channel quality measurement, the transmission node TP1 needs to transmit a CSI-RS pilot or a CRS pilot, so that the UE1 estimates channel state information (including PMI, RI, CQI) according to the CSI-RS or CRS, and in order to reduce interference of the UE1, the user needs to measure the channel of TP2, so as to feed back precoding information that causes the greatest interference to the UE 1. Since the node of cooperative transmission is transparent to the user and is the data sent by that transmission node, the user does not need to know. The base station only needs to inform the user of the CSI-RS and/or CRS which are sent and informed by the current data, and the CSI-RS and/or CRS which are sent and informed by the user DMRS are Quasi Co-located, wherein the Quasi-Location information is indicated through physical downlink shared channel resource element Mapping and Quasi Co-Location indication signaling (PDSCH RE Mapping and Quasi-Co-Location Indicator, PQI). Wherein, PQI is 1 parameter in the downlink control signaling format 2D in the physical layer signaling, including 2bit, as shown in table 1, table 1 is a meaning table of each state of the physical downlink shared channel resource unit mapping and quasi-common position indication notification signaling.

Each of the Parameter sets Parameter set 1 to Parameter set 4 includes a PDSCH RE mapping Parameter set and/or a QCL Parameter set, which is configured by high-layer signaling (configured by high layers), and notifies the terminal of the configuration by the high-layer signaling.

The understanding of the terminal alignment co-location type can be affected due to the different quasi co-location types. It is also necessary for the base station and the terminal to agree on or standardize a content on the quasi-co-location type. Regarding quasi-co-location types, including but not limited to the following discussions:

comprises a type set 1 and a type set 2, wherein the type set 1 comprises N₁Value of individual quasi co-location type 1

Type set 2 includes N₂Value of individual quasi co-location type 2

Wherein N is₁And N₂Is a positive integer.

The quasi-co-location type 1 indicates a quasi-co-location relationship between a user-specific demodulation reference signal DMRS and a cell-specific reference signal CRS. Preferably, the quasi-co-location type 1 represents user-specific demodulation reference signals DMRS and N sets of NZP CSI-RS resource quasi-co-locations in Class B, K >1, where N is a positive integer smaller than K, and K is a positive integer greater than 1. The quasi-co-location type 2 represents a quasi-co-location relationship of a channel state information reference signal CSI-RS and a cell-specific reference signal CRS.

Optionally, to limit the complexity of the standard and reduce the complexity of the terminal, the size of type set 1 and type set 2 may be limited.

Preferably, the type set 1 and the type set 2 include values in one or more of the following manners:

mode 1: type set 1 is { Type X₁}, Type set 2 is { Type Y₁}

Mode 2: type set 1 is { Type X₁}, Type set 2 is { Type Y₁,Type Y₂}

Mode 3: type set 1 is { Type X₁,Type X₂}, Type set 2 is { Type Y₁}

Some examples of quasi-co-locations are as follows: for example,

Type X₁DMRS and Class B, K, indicating that DMRS port 7-port 14 and CRS port 0-port 3 are quasi co-located>The N sets of CSI-RS ports 15-30 of 1 are quasi co-located.

Type X₂Indicating that DMRS port 7-port 14 and CRS port 0-port 3 are quasi co-located, and DMRS and CSI-RS port 15-port 30 are quasi co-located.

Type X₃Indicating that DMRS port 7-port 14 are quasi co-located with CRS port 0-port 3.

Type Y₁Represents Class B, K>1, the 1 st set of CSI-RS ports 15-30 and CRS₁Ports 0-3 are quasi co-located, …, the Kth set of CSI-RS ports 15-30 and CRS_KPort 0-3 are quasi co-located, where CRS₁，…，CRS_KThe CRS port groups may be different sequences with different port numbers or different frequency domain shifts.

Type Y₃Indicating that the CSI-RS port 7-port 14 and CRS port 0-port 3 are quasi co-located.

Of course, in practical definitions, other types of quasi co-location types may be defined, which are only illustrative and not limiting to the claims.

And the base station transmits the quasi-co-location type determined by the base station in a mode appointed by the terminal or a mode of high-level signaling transmission.
