Description

Quasi co-location information indication receiving method, 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 an apparatus for indicating and receiving quasi co-location information, a network side node, and a terminal.

Background

The multi-antenna system in the 5G network generally adopts a mixed architecture of a digital domain and an analog domain to take transmission performance and complexity into consideration. When the base station and the user terminal configure multiple beams, that is, the base station and the user terminal configure multiple antenna weights, it is necessary to ensure transmission rate by using beams with better channel quality between the user and the base station for communication through beam management. The beam Indication information of the downlink data channel in the existing 5G standard is included in quasi co-location (QCL) information, and the quasi co-location information is indicated by Transmission Control 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 thus is not described herein. When M >8, the network side activates 8 TCI states from TCIState 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 one spatial reception parameter QCL Type D for the ue at most, that is, can only configure one 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 indication of 3-bit TCI field in DCI format 1_1, or according to the protocol specification, a default TCI State, that is, one spatial reception information, is used, so that the ue is only supported to receive data using one analog beam. The user experience rate can be improved by using multiple analog beams to receive data, and the conventional quasi-co-location indication method cannot meet the requirement of simultaneously using multiple analog beams to receive data, so that the flexibility of a user side for receiving data 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 method and a device for receiving quasi co-location information indication, a network side node and a terminal.

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1:

fig. 2 is a schematic diagram of a quasi-co-location information indicating 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 indication information.

The quasi co-location information indication method provided by the embodiment of the invention is applied to network side nodes, for example, the network side nodes mainly comprise base stations, and certainly with the development of new generation access networks and communication networks, other network side nodes are not excluded from indicating quasi co-location information in the embodiment of the invention.

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

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

S202: selecting at least one piece of transmission control indication information from one of the 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 used for indicating the quasi co-location information is selected from one list in a plurality of lists configured for the terminal according to different scenes.

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

Each of the lists may correspond to a different scenario, that is, when the network side node configures multiple lists for the terminal, the lists are configured and divided according to the different scenarios.

Taking the scenario including the requirement for the terminal to receive data as an example, the requirement for the terminal to receive data includes that the terminal receives data by using a single beam and that the terminal receives data by using multiple beams, and the network side node at least performs configuration and division of the single beam list and the multiple beam list on the multiple lists. When the network side node selects at least one piece of transmission control indication information from one of the lists according to different scenes, specifically, if the network side node determines that the terminal receives data by adopting a single beam, the network side node determines a single beam list from the lists, selects one piece of transmission control indication information from the single beam list so as to meet the requirement that the terminal receives data by adopting the single beam, and if the network side node determines that the terminal receives data by adopting multiple beams, determines a multiple beam list from the lists, and selects at least two pieces of transmission control indication information from the multiple beam list so as to meet the requirement that the terminal receives data by adopting multiple beams simultaneously. In summary, the network side node can select the transmission control indication information according to the requirement of receiving data by using a single beam or multiple beams of the terminal, so as to meet the requirement of receiving data by using a single beam or multiple beams of the terminal.

In the embodiment of the present invention, only by taking a scenario including a requirement for a terminal to receive data as an example, a process of selecting at least one piece of transmission control indication information from one of a plurality of lists according to different scenarios is described, and processes of selecting at least one piece of transmission control indication information in other scenarios are similar.

When the network side node selects at least one piece of transmission control indication information, the selection may be performed according to the current beam state reported by the terminal, or according to other selection rules set by the network side node, which is not limited herein.

The network side node may determine different scenarios, further take the scenario that includes a terminal data reception requirement as an example, and the scenario includes a process that the terminal determines whether the user terminal employs multi-beam data reception as an example, and may determine whether the parameter for indicating multi-beam data reception is set to be valid or not, or determine whether the parameter for indicating single-beam data reception is set to be valid or not.

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

If the parameter indicating the multi-beam reception data can be preset to multi-tci-PresentInDCI, the network side node may determine by determining whether the multi-tci-PresentInDCI is set to enable, determine that the terminal receives data using a multi-beam if the network side node determines that the multi-tci-PresentInDCI is set to enable, and determine that the terminal receives data using a single beam if the multi-tci-PresentInDCI is not set to enable.

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

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

The number of the transmission control indication information selected by the network side node to indicate the quasi-co-location 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 an aggregate or an entirety. That is, when the base station indicates the selected at least two pieces of transmission control indication information to the terminal, the base station may directly indicate the identification information of the at least two pieces of transmission control indication information to the terminal, or may indicate the identification information of the transmission control indication information set including the at least two pieces of transmission control indication information to the terminal.

If the network side node selects at least two pieces of transmission control indication information, which is equivalent to indicating at least two pieces of quasi co-location information to the terminal, the network side node can support the terminal to receive data simultaneously, thereby improving the reliability of transmission, reducing the transmission delay and improving the flexibility of the terminal for receiving data.

Specifically, the quasi-co-location information included in the transmission Control indication information is used to indicate quasi-co-location information of a demodulation reference Signal (DMRS) of a Physical Downlink Control Channel (PDCCH), or quasi-co-location information of a DMRS of a Physical Downlink Shared Channel (PDSCH).

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 in 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 requirements that the terminal uses one analog beam to receive data and uses a plurality of analog beams to receive data simultaneously are met, and the flexibility of the terminal for receiving data is improved.

Example 2:

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

The network side node sends the selected transmission Control indication Information to the terminal through an indication signaling, where the indication signaling generally includes Downlink Control Information (DCI), that is, the selected transmission Control indication Information is generally indicated to the terminal through the DCI. In order to not occupy additional DCI overhead and not change DCI size of Rel-15, in the embodiment of the present invention, the selected identifier information of one piece of transmission control indication information or the selected identifier information of a transmission control indication information set including at least two pieces of transmission control indication information is indicated to the terminal.

Usually, the identification information of one piece of transmission control indication information is the same as the identification information of one set of transmission control indication information in terms of bits, e.g., 3 bits.

At least one list in the 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 two different pieces of transmission control indication information have the same type of quasi-co-location information, that is, the two different pieces of transmission control indication information are used for indicating the same type of quasi-co-location information of the quasi-co-location information.

The set of transmission control indication information stored in the list may be regarded as a configured set of transmission control indication information. The set of transmission control indication information may be configured in a configuration file in advance, for example, in 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 a 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.

Configuring indication information sets in the PDSCH-Config file may be as shown in fig. 3, wherein TCI-statesformultitaneoustransmissiontoaddmodlist SEQUENCE (SIZE (1.. maxNrofTCI-States)) OF TCI-State in the PDSCH-Config file indicates the number OF transmission control indication information in each indication information set, 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 configured transmission control indication information.

TCI-StateFormaSimultaneous Transmission ToReleaseListSEQUENCE (SIZE (1.. maxRofTCI-States)) in the PDSCH-Config file represents the number OF indication information sets, and the number OF the indication information sets is valued in the range OF 1 to maxRofTCI-States according to a preset rule.

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 one of the two lists includes at least one transmission control indication information set, and the list including the transmission control indication information may be configured as shown in table 1 below.

TABLE 1

Also taking the above as an example, if the network side node determines that the terminal receives data by using a single beam, the network side node may select one piece of transmission control indication information from table 1 to indicate the quasi co-location information.

The list including at least one transmission control indication information set may be constructed as shown in table 2 below, and the quasi-co-location types of TCI State 1 and TCI State3, TCI State 2 and TCI State3, and TCI State 5 and TCI State4 in table 2 are 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 receives data using multiple beams, the network side node may indicate two pieces of transmission control indication information included in one transmission control indication information set to the terminal according to the selected one transmission control indication information set in table 2.

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

Example 3:

on the basis of the foregoing embodiments, in an embodiment of the present invention, if at least two pieces of selected transmission control indication information are provided, the selecting at least one piece of transmission control indication information from one of the lists according to different scenes includes:

In order to implement the indication of quasi co-location information, when at least one list in a plurality of lists configured for the terminal includes at least one transmission control indication information set, if at least two pieces of transmission control indication information are selected, for example, when it is determined that the terminal receives data using multiple beams, the network side node selects the transmission control indication information set from the list including the transmission control indication information set, and since the selected transmission control indication information set includes at least two different pieces of transmission control indication information, the indication of multiple beams of the terminal can be implemented.

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

For the network side node and the terminal, whether the terminal receives data by using a single beam or by using multiple beams is known to both the network side node and the terminal, so when the terminal is determined to receive data by using the single beam, if the TCI field Index in the DCI is 0, the network side node indicates the TCI state 0 corresponding to Index being 0 for the terminal, and when the terminal is determined to receive data by using the multiple beams, if the TCI field Index in the DCI is 0, the network side node indicates the TCI state 1 and the TCI state3 corresponding to Index being 0 for the terminal.

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

Example 4:

The network side node activates the list and the 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 then at least two pieces of transmission control indication information are selected.

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.

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

And if the selected list and the candidate transmission control indication information set in the selected list are simultaneously activated in the plurality of lists, activating the second list through a third notification signaling, and activating the second candidate transmission control indication information set in the second list through the third notification signaling.

The first list and the second list may be the same and may be different, and the first set of candidate transmission control indication information and the second set of candidate transmission control indication information may be the same and 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 arbitrarily from the activated candidate transmission control indication information set, or may select the transmission control indication information set arbitrarily from the activated candidate transmission control indication information set according to the beam state reported by the terminal, and the like, which is not limited in the embodiment of the present invention.

Since the transmission control indication information set is stored in the list, the network side node is activated as a whole when activating the candidate transmission control indication information set.

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

The notification signaling comprises higher layer signaling or dynamic signaling, the higher layer signaling comprises Radio Resource Control (RRC) signaling or MAC-CE signaling, and the dynamic signaling comprises DCI signaling.

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

Example 5:

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

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

The network side node may pre-store a first preset number and a second preset number, where the first preset number and the second preset number are arbitrary, and usually the second preset number does not exceed the first preset number, and certainly, in order to not occupy overhead of additional 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 a 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.

At this time, the notification signaling used for activating the candidate transmission control indication information includes, as described above, a high-level signaling or a dynamic signaling, and taking the example that the notification signaling includes the high-level signaling and the high-level signaling includes an MAC-CE signaling, a second preset number of transmission control indication information sets are selected as the candidate transmission control indication information through the MAC-CE signaling for activation.

In the embodiment of the invention, the candidate transmission control indication information set is activated, so that the transmission control indication information set for quasi co-location information indication can be selected from the candidate transmission control indication information set, and the quasi co-location information indication is realized.

Example 6:

on the basis of the foregoing embodiments, an embodiment of the present invention further provides a method for receiving quasi co-location information at a terminal side, where the terminal receives identification information indicated by a network side node, where the identification information includes identification information of one piece of transmission control indication information or identification information of a transmission control indication information set including at least two pieces of 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 piece of transmission control indication information, or may also be identification information of a transmission control indication information set including at least two pieces of transmission control indication information.

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

The two different transmission control indication information have the same quasi-co-location information type.
