Description

Method and device for determining spatial information

Technical Field

The present invention relates to the field of wireless communications, and in particular, to a method and an apparatus for determining spatial information.

Background

NR supports beam-based transmission to improve system performance; in particular, the beams are characterized by reference signals corresponding to spatial information or reference signals corresponding to QCL-type in TCI.

In Rel-15, for PUSCH scheduled by DCI0_0, since no information is contained in DCI0_0 indicating spatial information of PUSCH, the protocol specifies that PUSCH scheduled by DCI0_0 has spatial information corresponding to the spatial information of PUCCH resource of the minimum ID of active BWP of the cell where PUSCH is located.

The Rel-16 protocol further specifies default spatial information of the PUSCH scheduled by DCI0_0, specifically, if the active BWP of the cell where the PUSCH is located does not configure PUCCH resources, the terminal considers that the spatial information of the PUSCH will refer to a reference signal of QCL-type in QCL of the CORESET with the minimum ID configured on the carrier or carrier group where the data channel is located or the related BWP, or the CORESET with the minimum ID configured on the carrier or carrier group where the data channel is located or the related BWP and associated with the search space monitored by the latest timeslot; and if the active BWP of the cell in which the PUSCH is positioned configures PUCCH resources and no configured PUCCH resource has no configured spatial information, the terminal considers that the spatial information of the PUSCH corresponds to default spatial information of the PUCCH resources configured on the related BWP.

However, the above method does not consider the problem of consistency between the path loss reference signal and the reference signal representing the spatial information when determining the spatial information of the PUSCH scheduled by the DCI0_0, so that the path loss reference signal is different from the reference signal representing the spatial information, thereby affecting the system performance.

Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present disclosure. It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

In the field of communications, it is important to determine spatial information (spatial information or spatial relationship) of a data channel. For a terminal device in an idle state or a connected state, such as UE, a Physical Uplink Shared Channel (PUSCH) related to the terminal device may be scheduled through Downlink Control Information (DCI), and it is determined that spatial Information of the PUSCH may also flexibly change according to the DCI.

In the field of communications, spatial information (spatial information or spatial relationship) is characterized by a reference signal or a reference signal corresponding to a QCL-type D (quasi-co-located type D, QCL-type D for short) in a TCI (Transmission Configuration Indicator) state. In other words, by referring to the reference signal representing the spatial information or the reference signal corresponding to QCL-type in the TCI state, specific spatial information can be known. Illustratively, if a certain reference signal is spatial information of a data channel, it refers to spatial information of the data channel, and can be obtained by referring to a certain reference signal. Or, for example, if a certain reference signal is spatial information of a data channel, it means that the spatial information characterized by a certain reference signal is spatial information of a data channel.

In the related art, in the case that the format of the DCI is DCI0_0, the spatial information of the PUSCH may be flexibly determined according to a QCL-TypeD reference signal or spatial information included in a Transmission Configuration Indicator (TCI) state related to the PUSCH; in the case that the format of the DCI is DCI0_1, the spatial information of the PUSCH may be flexibly determined according to a value of a channel sounding reference Signal Resource Indicator (SRI) field or a TCI field included in the DCI.

In the related art, a QCL-type reference signal included in a TCI state related to a PUSCH is currently a downlink reference signal, however, with the development of communication technology, the QCL-type reference signal included in the TCI state may be either a downlink reference signal or an uplink reference signal or a channel, and when the QCL-type reference signal is an uplink reference signal or a channel, the QCL-type reference signal cannot be used as a path loss reference signal of the PUSCH, and if the QCL-type reference signal is still used as spatial information, the path loss reference signal and the reference signal representing the spatial information are inconsistent, so that system performance is affected, and therefore the QCL-type reference signal cannot be used as spatial information of the PUSCH, that is, the spatial information of the PUSCH cannot be determined in the current manner.

In order to solve the above problem, the present embodiment discloses an application example of a method for determining spatial information.

Fig. 1 shows a flowchart of a method for determining spatial information according to an embodiment of the present disclosure, where the method may be applied to a User Equipment (UE), where the UE may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in remote surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety (wireless terminal in transportation), a wireless terminal in a smart city, a wireless terminal in a smart home, a wireless terminal in car networking, and the like, and in this embodiment, the method may include:

step S11, downlink control information DCI for scheduling a data channel is acquired.

Step S12, determining spatial information of the data channel according to the DCI and the reference signal type associated with the data channel or the TCI status parameter of the data channel.

In one possible implementation, the DCI format may be DCI0_0, and the data channel scheduled by the DCI may be a PUSCH. By acquiring the DCI for scheduling the data channel and determining the spatial information of the data channel according to the format of the DCI and the reference signal type associated with the data channel or the TCI state parameter of the data channel, the method and apparatus for determining the spatial information according to the embodiments of the present disclosure can still ensure that the spatial information can be determined normally when the reference signal type associated with the data channel changes and the current spatial information determination method cannot be applied.

As can be seen from the above disclosure embodiments, in the case where the DCI format is DCI0_0 and the reference signal type associated with the data channel is a non-downlink reference signal, it is difficult for the conventional spatial information determining method to use the reference signal as the spatial information of the data channel. Therefore, the method provided by the embodiment of the present disclosure may flexibly transform the determination manner of the spatial information according to the change of the reference signal type related to the data channel when the DCI format is DCI0_0, thereby ensuring normal implementation of the spatial information determination process as much as possible.

It should be noted that the DCI0_0 described herein is a corresponding parameter used for scheduling a PUSCH in one possible implementation manner, and when a name of the parameter for scheduling the PUSCH changes, the parameter may be flexibly selected according to an actual situation, and a determination condition for determining spatial information of a data channel in the foregoing disclosed embodiment is modified correspondingly, and is not limited to the following disclosed embodiments.

Specifically, in a case that the format of the DCI is DCI0_0, how to determine the spatial information according to the reference signal type associated with the data channel may be flexibly determined according to actual situations, and in one possible implementation, the step S12 may include:

step S121, determining a configuration state of a PUCCH resource of a relevant BWP of the data channel, where the relevant BWP includes an active BWP of a cell, a carrier, or a carrier group to which the data channel belongs.

Step S122, when the PUCCH resource is not configured by the relevant BWP, determining spatial information of the data channel according to a type of a first reference signal related to the data channel, where the first reference signal includes a QCL-type reference signal included in a TCI state corresponding to the first CORESET, and the first CORESET includes, when the PUCCH resource is not configured by the relevant BWP, a carrier or carrier group where the data channel is located, or a CORESET with a minimum ID on the relevant BWP, or a CORESET with a minimum ID that is configured on the carrier or carrier group where the data channel is located, or the relevant BWP and is associated with a search space monitored by the latest timeslot. Alternatively, the first and second electrodes may be,

and step S123, determining the spatial information of the data channel according to the PUCCH resource when the PUCCH resource is configured by the related BWP and the PUCCH resource is not configured with the spatial information or the QCL-TypeD reference signal. Alternatively, the first and second electrodes may be,

step S124, when the PUCCH resource is configured by the relevant BWP and at least one PUCCH resource configures spatial information or QCL-TypeD reference signal, the spatial information of the data channel is determined according to the type of the reference signal or QCL-TypeD reference signal corresponding to the spatial information included in the PUCCH resource.

Since the relevant BWP may be configured with a Physical Uplink Control Channel (PUCCH) resource or may not be configured with a PUCCH resource, the spatial information may be flexibly determined according to steps S122, S123, and S124 according to different PUCCH resource configurations on the relevant BWP, so that the normal implementation of the spatial information determination process is guaranteed as much as possible regardless of how the resource on the relevant BWP is configured.

In particular, it can be seen from step S122 that, in the case where the relevant BWP is not configured with PUCCH resources, spatial information can be flexibly determined according to the type of the first reference signal. In a possible implementation manner, when the PUCCH resource is not configured on the relevant BWP, the first reference signal cannot be obtained from the PUCCH resource, and therefore, in a case that the PUCCH resource is not configured on the relevant BWP, the core set with the smallest ID in the relevant carrier or a resource Control set (Control resource) configured on the BWP may be selected as the first core set, and the QCL-type reference signal included in the TCI state corresponding to the first core set may be used as the first reference signal.

In a possible implementation manner, when the related BWP is not configured with PUCCH resources, a core associated with the least recently monitored search space with the lowest core slot-ID in the core set associated with the search space monitored by the most recent slot (late slot) may be selected from the core sets configured on the related BWPs or carriers as the first core set, and the QCL-type reference signal included in the TCI state corresponding to the first core set may be used as the first reference signal.

In a possible implementation manner, the closest time slot may be a time slot that is closest to the receiving time slot of the current data channel and in which the monitored search space is associated with CORESET, for example, a time slot for receiving the PUSCH of the current data channel may be marked as N, and before the time slot N and the time slot N, if the search space monitored by the N-1 time slot is associated with CORESET, the N-1 time slot may be regarded as the closest time slot, and if the N-1 time slot does not need the monitored PDCCH, it is determined whether the search space monitored by the N-2 time slot is associated with CORESET, and so on, so that the closest time slot may be determined.

For example, in an example, three core sets with IDs of 3, 4, and 5 may be configured on the relevant BWP, where the core set with ID 4 is associated with the search space monitored by the latest timeslot, according to the above-described disclosed embodiments, the core set with the smallest ID, that is, the core set with ID 3, may be used as the first core set, the core set with ID 4 may also be used as the first core set, when the core set with ID 3 is used as the first core set, the first reference signal is the QCL-type reference signal included in the TCI state corresponding to the core set with ID 3, and when the core set with ID 4 is used as the first core set, the first reference signal is the QCL-type reference signal included in the TCI state corresponding to the core set with ID 4.

As the type of the first reference signal is different, the manner of determining the spatial information may also vary. In one possible implementation, step S122 may include:

step S1221, in a case that the PUCCH resource is not configured in the relevant BWP, determining whether the type of the first reference signal is a downlink reference signal or a channel, to obtain a first determination result.

In step S1222, if the first determination result is yes, the first reference signal is used as the spatial information of the data channel.

In step S1223, if the first determination result is negative, the second reference signal is used as the spatial information of the data channel.

As can be seen from the foregoing disclosure, in a possible implementation manner, when the first reference signal is a downlink reference signal or a channel, the first reference signal may be directly used as spatial information of a data channel, and in an example, the spatial information may be a periodic reference signal.

In case that the first reference signal is not a downlink reference signal or channel, for example, in case that the first reference signal is an uplink reference signal, if the spatial information is determined to be the first reference signal, the system performance will be affected,

in a possible implementation manner, in a case that the first determination result is negative, that is, in a case that the first reference signal is not a downlink reference signal or a channel, the second reference signal may be further used as spatial information of the data channel. The second reference signal is a reference signal related to the data channel, and specific implementation manners thereof may refer to the embodiments disclosed later, which are not expanded herein.

Through the above process, the spatial information can be flexibly acquired from the reference signal related to the data channel under the condition that the first reference signal cannot be directly used as the spatial information, and the normal implementation of the spatial information determination process is ensured.

Similarly, it can be seen from step S123 that, when the PUCCH resource is configured for the relevant BWP, but no PUCCH resource is configured with spatial information or QCL-type reference signal, since no spatial information or QCL-type reference signal is configured in the PUCCH resource, the reference signal or QCL-type reference signal corresponding to the spatial information cannot be directly acquired from the PUCCH resource as the spatial information, and thus the spatial information of the data channel can be flexibly determined according to the PUCCH resource at this time.

Specifically, how to determine the spatial information of the data channel according to the PUCCH resource, the implementation process thereof may also be flexibly determined according to the type of the spatial information related in the PUCCH resource, and in a possible implementation manner, step S123 may include:

step S1231, when the PUCCH resource is configured by the relevant BWP and the PUCCH resource is not configured with the spatial information or the QCL-TypeD reference signal, determining whether a carrier or a carrier group where the data channel is located or the relevant BWP is configured with CORESET, and obtaining a second determination result.

Step S1232, if the second determination result is yes, determining spatial information of the data channel according to a type of a third reference signal or a second reference signal related to the data channel, where the third reference signal includes a QCL-type reference signal included in a TCI state corresponding to the second CORESET, the second CORESET includes, when the related BWP configures a PUCCH resource, a CORESET with a minimum ID configured on a carrier or a carrier group where the data channel is located or a related BWP or a CORESET with a minimum ID configured on a carrier or a carrier group where the data channel is located or a related BWP and related to a search space monitored by a latest timeslot, and the second reference signal includes a QCL-type reference signal included in an active TCI state with a minimum ID related to the data channel.

Step S1233, if the second determination result is negative, determining spatial information of the data channel according to a type of the second reference signal associated with the data channel.

It can be seen from the foregoing disclosure that, in the case that a relevant BWP configures PUCCH resources and each PUCCH resource does not configure spatial information or QCL-type reference signal, it may be first determined whether a carrier or a carrier group where a data channel is located or a relevant BWP is configured with CORESET, and then, according to a difference in CORESET configuration on the carrier or the carrier group where the data channel is located or the relevant BWP, a corresponding manner may be flexibly selected to determine spatial information of the data channel.

The second core set and the first core set are only used to distinguish the carrier or the carrier group where the data channel is located, or the core set of the minimum ID configured by the relevant BWP, or the core set of the minimum ID associated with the search space monitored by the latest timeslot in the configuration state of different PUCCH resources, rather than limiting the implementation manners of the two core sets, that is, the specific configuration situations of the first core set and the second core set may be the same or different, which is not limited in the embodiment of the present disclosure.

When the carrier or the carrier group where the data channel is located or the related BWP is configured with CORESET, the spatial information of the data channel may be determined according to a third reference signal or a second reference signal, where the determination process of the third reference signal may be: and selecting the CORESET with the smallest ID or the CORESET with the smallest ID associated with the search space monitored by the nearest time slot from the CORESETs configured on the carrier or the carrier group where the data channel is located or the related BWP, and using the QCL-TypeD reference signal included in the TCI state corresponding to the second CORESET as a third reference signal. The second reference signal determination process may be: and selecting the active TCI state with the smallest ID from the active TCI states related to the data channel, and using the QCL-TypeD reference signal included in the selected active TCI state as a second reference signal.

Specifically, how to determine the spatial information of the data channel under the condition that the carrier or the carrier group where the data channel is located or the correlated BWP is configured with the CORESET according to the state of the third reference signal or the second reference signal, the process may be flexibly determined according to the actual situation, and in a possible implementation manner, step S1232 may include:

step S12321, if the second determination result is yes, determines whether the type of the third reference signal is a downlink reference signal or a channel, so as to obtain a third determination result.

In step S12322, if the third determination result is yes, the third reference signal is used as the spatial information of the data channel.

In step S12323, if the third determination result is negative, the second reference signal is used as the spatial information of the data channel.

It can be seen from the foregoing disclosure that, when the second determination result is yes, the spatial information of the data channel may be determined according to the type of the third reference signal, that is, if the third reference signal is a downlink reference signal or a downlink reference signal, the third reference signal may be directly used as the spatial information of the data channel, and if the third reference signal is a non-downlink reference signal or a non-downlink reference signal, such as an uplink reference signal, in a possible implementation manner, the second reference signal may be used as the spatial information of the data channel.

As can be seen from the above disclosure, in a case that the relevant BWP is configured with PUCCH resources, each PUCCH resource is not configured with spatial information or QCL-TypeD reference signal, but a data channel is configured with CORESET on the carrier or the carrier group or the relevant BWP, the process of determining the data channel spatial information according to the third reference signal type or the second reference signal may be:

in a case that the third reference signal is a downlink reference signal or a channel, the third reference signal is used as spatial information of a data channel, and in an example, the spatial information at this time may be a periodic reference signal; alternatively, the first and second electrodes may be,

when the third reference signal is a non-downlink reference signal or a channel, the second reference signal is used as spatial information of the data channel, and in an example, the spatial information at this time may be a periodic reference signal.

When the correlated BWP or carrier is configured with PUCCH resources, each PUCCH resource is not configured with spatial information or QCL-type reference signal, but a carrier or carrier group where the data channel is located or correlated BWP is configured with CORESET, the spatial information of the data channel is flexibly determined according to the third reference signal or the second reference signal, which can improve the flexibility of the spatial information determination process and further ensure the complete implementation of the spatial information determination process.

In a case where the relevant BWP or the carrier is configured with PUCCH resources, each PUCCH resource is not configured with spatial information or QCL-type reference signal, and the carrier or the carrier group where the data channel is located or the relevant BWP is not configured with CORESET, and the second reference signal is directly used as the spatial information of the data channel in a case where the second reference signal is a downlink reference signal or a downlink channel, in an example, the spatial information at this time may be a periodic reference signal.

Similarly, as can be seen from step S124, when the PUCCH resource is configured in the relevant BWP, and when at least one PUCCH resource is configured with spatial information or a QCL-type reference signal, the spatial information of the data channel may be determined directly according to the type of the reference signal or the QCL-type reference signal corresponding to the spatial information included in the PUCCH resource. In one possible implementation, step S124 may include:

step S1241, when the PUCCH resource is configured by the relevant BWP and at least one PUCCH resource is configured with spatial information or QCL-type reference signal, selects a PUCCH resource with a minimum ID from the PUCCH resources configured with spatial information or QCL-type reference signal or from the PUCCH resources configured with only one spatial information or QCL-type reference signal as the PUCCH resource to be determined.

Step S1242, determining whether the type of the reference signal or the QCL-TypeD reference signal corresponding to the spatial information included in the PUCCH resource to be determined is a downlink reference signal or a channel, to obtain a fourth determination result.

Step S1243, in case that the fourth determination result is yes, taking a reference signal or a QCL-TypeD reference signal corresponding to the spatial information included in the PUCCH resource to be determined as the spatial information of the data channel;

in step S1244, if the fourth determination result is negative, the third reference signal or the second reference signal is used as the spatial information of the data channel.

Specifically, in one possible implementation manner, step S1244 may include:

step S1441, when the PUCCH resources are configured by the relevant BWP and at least one PUCCH resource configures spatial information or QCL-TypeD reference signal, determines whether a carrier or a carrier group where the data channel is located or the relevant BWP is configured with CORESET, and obtains a fifth determination result.

In step S12442, if the fifth determination result is yes, it is determined whether the type of the third reference signal is a downlink reference signal or a channel, so as to obtain a sixth determination result.

In step S124421, if the sixth determination result is yes, the third reference signal is used as the spatial information of the data channel.

In step S124422, if the sixth determination result is negative, the second reference signal is used as the spatial information of the data channel.

In step S1243, if the fifth determination result is negative, the second reference signal is used as the spatial information of the data channel.

Wherein, since at least one PUCCH resource configures spatial information or QCL-type reference signal among PUCCH resources configured by BWP, there may be a plurality of PUCCH resources configured with spatial information or QCL-type reference signal, and at this time, a PUCCH resource with the smallest ID may be selected as a PUCCH resource to be determined from the plurality of PUCCH resources configured with spatial information or QCL-type reference signal, or from the plurality of PUCCH resources configured with only one spatial information or QCL-type reference signal, so that, in a case where a reference signal or QCL-type reference signal corresponding to spatial information included in the PUCCH resource to be determined is a downlink reference signal or channel, a reference signal or QCL-type reference signal corresponding to the spatial information may be used as spatial information of a data channel, otherwise, a third reference signal or a second reference signal as mentioned in the above-disclosed embodiment may be used, as spatial information of the data channel, as spatial information.

It should be noted that, in the above-mentioned embodiment, in the case that the format of the DCI is DCI0_0, the determination manners of the various spatial information implemented according to different determination conditions may be flexibly combined according to actual situations, and are not limited in the embodiment of the present disclosure.
