Description

Quasi co-location information indication receiving method and device, network side node and terminal

Technical Field

The present invention relates to the field of wireless technologies, and in particular, to a method and apparatus for receiving quasi co-location information indication, a network node, and a terminal.

Background

Multi-antenna systems in 5G networks typically employ a hybrid architecture of the digital domain and the analog domain to compromise transmission performance and complexity. When the base station side and the user side are configured with a plurality of beams, that is, when the base station side and the user side are configured with a plurality of antenna weights, the user and the base station need to communicate by using the beams with better channel quality through beam management so as to ensure the transmission rate. The beam indication information of the downlink data channel in the existing 5G standard is included in quasi co-location (QCL) information, which is indicated by transmission control indication (Transmission Configuration Indication, TCI) information. The network side configures a TCI State List for the user in the PDSCH-config, wherein the TCI State List comprises M TCI State, and M is determined according to the capability of the user side. The configuration information of the TCI-State is shown in fig. 1, and is believed to be clear to those skilled in the art and is not described herein. When M >8, the network side activates 8 TCI states from the TCI State List using MAC-CE signaling.

Each TCI State indicates 1 or 2 QCL types, and when 2 QCL types are indicated, the indicated two QCL types cannot be the same. That is, each TCI State in the existing 5G standard can only configure a spatial reception parameter QCL Type D for the ue at most, that is, only can configure a beam indication information for the ue at most, specifically, when the network side schedules the PDSCH, only one TCI State can be indicated for the user, for example, according to the 3-bit TCI field in DCI format 1_1, or a default TCI State, that is, a spatial reception information, is used according to the protocol, so that only the ue is supported to use one analog beam to receive data. The use of multiple analog beams to receive data can improve the user experience rate, but the existing quasi co-location indication method cannot meet the requirement of simultaneously using multiple analog beams to receive data, so that the flexibility of receiving data by the user terminal is poor. At present, no technical scheme capable of effectively solving the problem exists.

Detailed Description

In order to improve the flexibility of receiving data by a terminal, the embodiment of the invention provides a quasi co-location information indication receiving method, a quasi co-location information indication receiving device, a network side node and a terminal.

For the purpose of promoting an understanding of the principles and advantages of the invention, reference will now be made in detail to the drawings, in which embodiments illustrated in the drawings are intended to illustrate, but not limit the invention to the specific embodiments illustrated. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1:

fig. 2 is a schematic diagram of a quasi co-location information indication process according to an embodiment of the present invention, where the process includes the following steps:

s201: the terminal is configured with a plurality of lists including transmission control instruction information.

The quasi co-location information indication method provided by the embodiment of the invention is applied to the network side node, for example, the network side node mainly comprises a base station, and certainly, along with the development of a new generation access network and a communication network, the quasi co-location information indication of other network side nodes is not excluded in the embodiment of the invention.

The network side node configures a plurality of lists including transmission control indication information for the terminal, wherein the plurality of lists are specifically at least two lists, the transmission control indication information in each list includes K quasi co-location information, namely QCL information, and specifically the quasi co-location information includes space quasi co-location information QCL-Type D.

In the embodiment of the invention, the configuration information and the structure of the existing transmission control indication information can be not modified.

S202: and selecting at least one transmission control indication information from one list in the multiple lists according to different scenes, wherein the transmission control indication information comprises quasi co-location information.

When the network side node indicates the quasi co-location information to the terminal, at least one piece of transmission control indication information for quasi co-location information indication is selected from one of a plurality of lists configured for the terminal according to different scenes, and the target transmission control indication information comprises the quasi co-location information, so that the quasi co-location information can be indicated to the terminal through the at least one piece of transmission control indication information, namely, the selected at least one piece of transmission control indication information is used for quasi co-location information indication.

The network side node may select one or more transmission control indication information for indicating the quasi co-located information.

Each list in the plurality of lists may correspond to a different scenario, i.e. when the network side node configures the plurality of lists for the terminal, the lists are configured and divided according to the different scenario.

In the following, a scenario includes an example of a terminal receiving data requirement, where the terminal receiving data requirement includes that the terminal adopts single beam to receive data and the terminal adopts multiple beams to receive data, and a network side node configures and divides at least a plurality of lists into a single beam list and a multiple beam list. When the network side node selects at least one transmission control instruction information from one list in a plurality of lists according to different scenes, specifically, if the network side node determines that the terminal adopts a single beam to receive data, the network side node determines the single beam list in the plurality of lists, selects one transmission control instruction information in the single beam list so as to meet the requirement that the terminal adopts the single beam to receive data, and if the network side node determines that the terminal adopts multiple beams to receive data, determines the multiple beam list in the plurality of lists, and selects at least two transmission control instruction information in the multiple beam list so as to meet the requirement that the terminal adopts multiple beams to receive data simultaneously. In summary, the network side node can select transmission control indication information according to the requirement of the terminal for receiving data by single beam or multiple beams, thereby meeting the requirement of the terminal for receiving data by single beam or simultaneously receiving data by multiple beams.

In the embodiment of the present invention, only the case that the scene includes the data requirement received by the terminal is taken as an example, the process of selecting at least one transmission control instruction information from one list in a plurality of lists according to different scenes is described, and the process of selecting at least one transmission control instruction information in other scenes is similar, so that the details are not repeated in the embodiment of the present invention, and it is believed that those skilled in the art perform corresponding settings according to the actual scene and requirement.

The network side node may select at least one transmission control instruction according to the current beam state reported by the terminal, or may select the transmission control instruction according to other selection rules set by the network side node itself, which is not limited herein.

The network side node may determine different scenarios, and take a scenario including a terminal receiving data requirement as an example, where the scenario includes a process of determining whether the user terminal adopts multi-beam receiving data as an example, and may determine whether a parameter for indicating multi-beam receiving data is set to be valid, or may determine whether a parameter for indicating single-beam receiving data is set to be valid.

It should be noted that, since the prior art does not support the user terminal to receive data by using multiple beams, if the determination is made based on whether the parameter for indicating the data received by multiple beams is set to be valid, the parameter for indicating the data received by multiple beams needs to be preset in the network side node, for example, the parameter for indicating the data received by multiple beams may be preset as multi-tci-presentingii, or may be preset as other parameters, so long as the parameter can be used for indicating whether the data received by multiple beams is used, which is not limited herein.

If the parameter for indicating the multi-beam received data can be preset to be multi-tci-presentingi, the network side node can determine whether the multi-tci-presentingi is set to enable, if the network side node determines that the multi-tci-presentingi is set to enable, it is determined that the terminal adopts the multi-beam to receive the data, and if the multi-tci-presentingi is not set to enable, it is determined that the terminal adopts the single-beam to receive the data.

S203: and indicating the selected at least one transmission control indication information to the terminal.

After the network side node selects at least one transmission control indication information, the selected at least one transmission control indication information is indicated to the terminal, so that quasi co-location information included in the at least one transmission control indication information is indicated to the terminal.

The number of the transmission control indication information selected by the network side node for indicating the quasi co-located information may be one or more, and if the number of the selected transmission control indication information is at least two, the at least two transmission control indication information may be indicated separately, and may be indicated as a set or as a whole. That is, when the base station indicates the selected at least two transmission control instruction information to the terminal, the base station may directly indicate the identification information of the at least two transmission control instruction information to the terminal, or may indicate the identification information of the transmission control instruction information set including the at least two transmission control instruction information to the terminal.

If the network side node selects at least two transmission control indication information, the indication is equivalent to at least two quasi co-location information for the terminal, the terminal can be supported to simultaneously receive data, the reliability of transmission is improved, the transmission delay is reduced, and the flexibility of the terminal for receiving data is improved.

Specifically, the transmission control indication information includes quasi co-location information for indicating quasi co-location information of demodulation reference signals (DMRS, demodulation Reference Signal) of a physical downlink control channel (PDCCH, physical Downlink Control Channel) or quasi co-location information of DMRS of a downlink shared channel (PDSCH, physical Downlink Shared CHannel).

In the embodiment of the invention, a plurality of lists comprising transmission control indication information are configured for the terminal, the transmission control indication information comprises quasi co-location information, at least one transmission control indication is selected from one of the lists according to different scenes, and the selected at least one transmission control indication information is indicated to the terminal, so that the requirement that the terminal receives data by using one analog wave beam and simultaneously receives data by using a plurality of analog wave beams is met, and the flexibility of the terminal for receiving the data is improved.

Example 2:

on the basis of the foregoing embodiment, in an embodiment of the present invention, the indicating the at least one target transmission control indication information to the terminal includes:

The network side node sends the selected transmission control indication information to the terminal through indication signaling, wherein the indication signaling generally comprises downlink control channel information (Downlink Control Information, DCI), namely the selected transmission control indication information is generally indicated to the terminal through DCI. In order to not occupy extra DCI overhead and not change the DCI size of Rel-15, in the embodiment of the invention, the identification information of the selected transmission control indication information or the identification information of the selected transmission control indication information set comprising at least two transmission control indication information is indicated to the terminal.

Typically, the identification information of one transmission control indication information is the same as the bits occupied by the identification information of one transmission control indication information set, for example, 3 bits.

At least one list in the multiple lists configured by the network side node for the terminal comprises at least one transmission control indication information set, and each transmission control indication information set comprises at least two different transmission control indication information.

The quasi co-location information types of the two different transmission control indication information are the same, i.e. the quasi co-location information types of the two different transmission control indication information used for indicating the quasi co-location information are the same.

The set of transmission control indication information stored in the list may be regarded as a set of configured transmission control indication information. The set of transmission control indication information may be configured in advance in a configuration file, such as a PDSCH-Config file.

The configured transmission control indication information sets are configured by the base station according to the beam state reported by the user terminal, the configured transmission control indication information, namely the TCI state and the preset rule, the configuration process is not limited in the embodiment of the present invention, and each configured transmission control indication information set includes at least two different transmission control indication information.

The configuration OF the indication information sets in the PDSCH-Config file may be as shown in fig. 3, in the PDSCH-Config file TCI-StatesforSimultaneousTransmissionToAddModList SEQUENCE (SIZE (1..maxnroftci-States)) OF TCI-State, indicating the number OF transmission control indication information in each indication information set, where the number OF transmission control indication information is valued in a range from 1 to maxNrofTCI-States according to a preset rule, and maxNrofTCI-States represents the maximum number OF transmission control indication information that has been configured.

TCI-StatesforSimultaneousTransmissionToReleaseList SEQUENCE (SIZE (1..maxnroftci-States)) OF TCI-States id in the PDSCH-Config file indicates the number OF instruction information sets, and the number OF instruction information sets is valued according to a preset rule in the range OF 1 to maxNrofTCI-States.

Other fields in the PDSCH-Config file are believed to be clear to those skilled in the art and are not described in detail in the embodiments of the present invention.

It is assumed that the network side node configures two lists including transmission control indication information for the terminal, and at least one transmission control indication information set is included in one of the two lists, and a list structure including the transmission control indication information can be shown in table 1 below.

TABLE 1

Also taking the above example, if the network side node determines that the terminal uses a single beam to receive data, the network side node may perform the indication of the quasi co-location information according to selecting one transmission control indication information in the table 1.

The list including at least one transmission control indication information set may be constructed as shown in table 2 below, with the quasi co-sited types of TCI State 1 and TCI State3, TCI State 2 and TCI State3, TCI State 5 and TCI State4 in table 2 being the same.

TABLE 2

Index	TCI state sets
		0	{TCI state 1,TCI state 3}
1	{TCI state 2,TCI state 3}
		2	{TCI state 5,TCI state 4}
…	…
		N	{TCI state 6,TCI state 0}

If the network side node determines that the terminal adopts multi-beam to receive data, the network side node may indicate two pieces of transmission control indication information included in the one transmission control indication information set to the terminal according to the one transmission control indication information set selected in the table 2.

In the embodiment of the invention, the identification information of one transmission control indication information or the identification information of the transmission control indication information set comprising at least two transmission control indication information is indicated to the terminal, so that the indication of quasi co-location information is realized on the basis of not occupying the overhead of additional DCI signaling.

Example 3:

based on the foregoing embodiments, in the embodiment of the present invention, if the selected transmission control instruction information is at least two, the selecting at least one transmission control instruction information from one list of the multiple lists according to different scenarios includes:

In order to realize the indication of quasi co-location information, when at least one list including at least one transmission control indication information set exists in a plurality of lists configured for the terminal, if at least two transmission control indication information are selected, for example, when the terminal is determined to receive data by using multiple beams, the transmission control indication information set is selected from the list including the transmission control indication information set, and the selected transmission control indication information set includes at least two different transmission control indication information, so that the indication of multiple beams of the terminal can be realized.

Taking the above table 1 and table 2 as an example, the network side node indicates the Index of the one transmission control instruction information selected in table 1 as the identification information of the one transmission control instruction information to the terminal, and the network side node indicates the Index of the one transmission control instruction information selected in table 2 as the identification information of the one transmission control instruction information set to the terminal.

For both network side nodes and terminals, whether the terminal adopts single beam reception data or multi-beam reception data is known to both sides, so when determining that the terminal adopts single beam reception data, if TCI field Index in DCI is 0, the network side node indicates TCI state 0 corresponding to index=0 for the terminal, and when determining that the terminal adopts multi-beam reception data, if TCI field Index in DCI is 0, the network side node indicates TCI state 1 and TCI state 3 corresponding to index=0 for the terminal.

In the embodiment of the invention, the transmission control indication set is selected to select at least two different transmission control indication information, so that the indication of quasi co-location information can be realized.

Example 4:

The network side node activates a list and candidate transmission control indication information in a plurality of lists configured for the terminal, so that a transmission control indication information set is selected from the candidate transmission control indication information, and further, the selection of at least two transmission control indication information is realized.

The selected list may be activated first in the plurality of lists, and then the candidate transmission control indication information set may be activated in the selected list, and the selected list and the candidate transmission control indication information set in the selected list may be activated simultaneously.

And if the selected list is activated first and then the candidate transmission control indication information set is activated in the selected list, activating the selected first list through a first notification signaling and then activating the first candidate transmission control indication information set in the first list through a second notification signaling.

And if the selected list and the candidate transmission control indication information set in the selected list are activated at the same time in the multiple lists, activating a second list through a third signaling, and activating a second candidate transmission control indication information set in the second list through the third signaling.

The first list and the second list may be the same or may be different, and the first candidate transmission control indication information set and the second candidate transmission control indication information set may be the same or may be different.

When the network side node selects the transmission control indication information set, the network side node may select the transmission control indication information set from the activated candidate transmission control indication information set at will, or may select the transmission control indication information set from the activated candidate transmission control indication information set according to the beam state reported by the terminal, which is not limited in the embodiment of the present invention.

Since the list contains the transmission control indication information set, the network node activates the candidate transmission control indication information set as a whole.

The process of activating the selected list and the candidate transmission control information indication information set by using the notification instruction is believed to be clear to those skilled in the art, and thus will not be described in detail in the embodiments of the present invention.

The notification signaling includes higher layer signaling including Radio Resource Control (RRC) signaling or MAC-CE signaling or dynamic signaling including DCI signaling.

In the embodiment of the invention, the transmission control indication information set is selected from a plurality of lists configured for the terminal, and at least two different transmission control indication information sets are further selected, so that the indication of quasi co-location information is realized.

Example 5:

based on the foregoing embodiments, in the embodiment of the present invention, activating the candidate transmission control indication information set in the selected list includes:

If the number of the configured transmission control indication information sets in the selected list is greater than the first preset number M, selecting a second preset number N of candidate transmission control indication information sets in the selected list for activation, otherwise, activating each transmission control indication set in the selected list as a candidate indication information set, wherein M and N are positive integers, and M and N can be equal or unequal.

The network side node may store in advance a first preset number and a second preset number, where the first preset number and the second preset number are arbitrary, and generally, the second preset number does not exceed the first preset number, and, of course, in order to not occupy additional overhead of DCI signaling, the preset number does not exceed a maximum number indicated by bits for indicating a beam, taking the prior art as an example, the bits for indicating the beam are 3 bits, and the maximum number indicated by the 3 bits is 8, so preferably, the first preset number and the second preset number do not exceed 8.

The notification signaling adopted by the candidate transmission control indication information is shown as the above, including high-layer signaling or dynamic signaling, taking the example that the high-layer signaling includes the high-layer signaling and the high-layer signaling includes the MAC-CE signaling, and selecting a second preset number of transmission control indication information sets as the candidate transmission control indication information through the MAC-CE signaling for activation.

Because the candidate transmission control indication information set is activated in the embodiment of the invention, the transmission control indication information set for indicating the quasi co-location information can be selected from the candidate transmission control indication information set, thereby realizing the indication of the quasi co-location information.

Example 6:

on the basis of the above embodiments, the embodiments of the present invention further provide a method for receiving quasi co-location information at a terminal, where the terminal receives identification information indicated by a node at a network side, where the identification information includes identification information of one transmission control indication information or identification information of a transmission control indication information set including at least two transmission control indication information.

The data receiving method provided by the embodiment of the invention is applied to the terminal, and the terminal can receive the identification information of at least one transmission control indication information indicated by the network side node.

Specifically, the identification information indicated by the network side node received by the terminal may be identification information of one transmission control indication information, or may be identification information of a transmission control indication information set including at least two transmission control indication information.

The network side node issues a plurality of lists configured for the terminal including transmission control indication information to the terminal before indicating the quasi co-location information to the terminal, specifically before receiving the identification information indicated by the network side node, the method further includes:

The quasi co-location information types of the two different transmission control indication information are the same.
