Description

Priority determination method and device

Technical field

The embodiments of the present application relate to the field of communication technology.

Background technique

Large-scale multiple-input multiple-output (MIMO) technology is a key technology of new radio (NR, New radio) systems, including, for example, the research on frequency bands below 6 GHz and above 6 GHz. With the increase of frequency bands, the fading and loss in transmission will increase accordingly. The beamforming technology has become a key technology in massive MIMO technology because it can effectively compensate for the fading.

In the beamforming technology, the network device will indicate the beamforming weighting factor used by the physical channel and/or physical signal to the terminal device to ensure that the terminal device uses a matched spatial receiving filter to receive the signal, thereby maximizing the network The equivalent channel quality between equipment and terminal equipment improves transmission efficiency.

In order to further improve transmission efficiency and increase coverage, multiple transmission points (TRP, transmission points) or multiple antenna panels (panels) can also be used to jointly transmit for terminal devices. Multiple TRPs can be jointly sent and received, or they can be independently scheduled to reduce the interaction delay between multiple TRPs. When multiple TRPs are independently scheduled, the resources for sending data may overlap in the time domain. The specific overlap modes include three modes: partial overlap, complete overlap, and no overlap at all.

The following uses examples to illustrate the scenarios of the embodiments of the present application, but the present application is not limited to this.

FIG. 1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a case where terminal devices and network devices are taken as examples. As shown in FIG. 1, a communication system 100 may include a network device 101 and

terminal devices

102 and 103. For simplicity, FIG. 1 only uses two terminal devices and one network device as an example for description, but the embodiment of the present application is not limited to this.

In the embodiment of the present application, the network device 101 and the

terminal devices

102 and 103 may perform existing service or service transmission that can be implemented in the future. For example, these services may include, but are not limited to: enhanced Mobile Broadband (eMBB), large-scale machine type communication (mMTC, massive Machine Type Communication), and high-reliability and low-latency communication (URLLC, Ultra-Reliable and Low). -Latency Communication), etc.

In the embodiment of the present application, the beamforming weighting factor may be characterized by spatial QCL characteristics (also referred to as'QCL-TypeD' characteristics, or spatial QCL assumptions, etc.) in the transmission configuration indication (TCI, transmission configuration indication) state.

For the convenience of description, the TCI state that characterizes the spatial QCL characteristics is referred to as the spatial TCI state in this article, and it is also referred to as the TCI state if it does not cause ambiguity or ambiguity. In addition to the spatial QCL feature (QCL-TypeD), the TCI state also includes three other QCL types, QCL-TypeA, QCL-TypeB, and QCL-TypeC. These three QCL types do not include spatial QCL characteristics, but include one or more combinations of large-scale transmission characteristics such as Doppler frequency shift, Doppler spread, average delay, and delay spread of the reference signal port. .

In the embodiment of the present application, the signal may include an uplink signal (transmitted from a terminal device to a network device) and/or a downlink signal (transmitted from a network device to a terminal device). Both the downlink signal or the uplink signal may include a physical channel and/or a physical signal.

The physical channels include, for example, the physical downlink control channel (PDCCH, physical downlink control channel), the physical downlink shared channel (PDSCH, physical downlink shared channel), the physical broadcast channel (PBCH, physical broadcast channel), and the physical uplink control channel (PUCCH, physical). uplink control channel), physical uplink shared channel (PUSCH, physical uplink shared channel), etc.

The physical signal includes, for example: channel state information reference signal (CSI-RS, channel state information reference signal), tracking reference signal (TRS, tracking reference signal), phase tracking reference signal (PT-RS, phase tracking reference signal), synchronization signal (SS, synchronization signal), sounding reference signal (SRS, sounding reference signal), etc.

The beamforming weighting factor (that is, the spatial TCI state) of the physical channel indicates the spatial QCL characteristics of the demodulation reference signal (DMRS, demodulation reference signal) of the physical channel. Similarly, the spatial TCI status of a physical signal indicates the spatial QCL characteristics of the physical signal. Therefore, the same (or different) spatial TCI state between the physical channels can be equivalent to the same (or different) spatial QCL characteristics between the DMRS of the physical channels. Similarly, the physical channel and the physical signal have the same (or different) spatial TCI state, which can be equivalent to the physical channel's DMRS and the physical signal having the same (or different) spatial QCL characteristics; the physical signals have the same (or different) characteristics The spatial TCI state is equivalent to the same (or different) spatial QCL characteristics between physical signals.

In NR, the TCI status of the PDSCH can be dynamically indicated by downlink control information (DCI). When the high-level parameter tci-PresentInDCI is enabled, the network device will pass the'Transmission configuration indication' in the DCI Field to indicate the TCI status of the PDSCH. When tci-PresentInDCI is disabled, the network device will not dynamically indicate the TCI status of the PDSCH through the DCI, but determine the TCI status according to different rules preset in different situations. The PDCCH is transmitted through the resources in the control resource set (CORESET, control resource set), so the TCI state of the PDCCH is determined by the TCI state of the CORESET used during transmission.

In NR, when the high-level parameter tci-PresentInDCI is disabled or not configured, if the time offset between the received downlink DCI and the corresponding PDSCH is less than a certain threshold, the terminal device may assume the DMRS port of the PDSCH and the following CORESET The reference signal (RS) is quasi co-located (QCL), and the CORESET is the one or more CORESETs of the currently activated bandwidth part (BWP, bandwidth part) in the latest slot, which has the smallest number, and is related to the PDCCH QCL CORESET indicated.

In NR, if the'QCL-TypeD' of the DMRS of the PDSCH and the DMRS of the PDCCH are not the same, and they overlap in at least one symbol, the terminal device will expect to preferentially receive the PDCCH associated with the CORESET.

In the embodiment of the present application, the PDCCH is associated with the CORESET, which means that the PDCCH will be sent on the associated CORESET; the PDSCH is associated with the CORESET, which means that the spatial TCI state of the PDSCH is the same as the spatial TCI state of the associated CORESET.

Fig. 2 is an example diagram of determining the reception priority when the PDCCH and PDSCH resources in the NR overlap in the time domain. As shown in Figure 2, for example, the time slot for scheduling the PDSCH is configured with 3 CORESETs, namely CORESET1 (abbreviated as C1), CORESET2 (abbreviated as C2) and CORESET3 (abbreviated as C3), which are respectively configured in symbol 1, symbol 2 and symbol 3. Above, the TCI states of the three are TCI1, TCI2 and TCI3 respectively.

PDSCH may be transmitted on symbol 3, because the time offset between symbol 3 and downlink DCI is less than a certain threshold, the terminal device can determine: if PDSCH is transmitted on symbol 3, the spatial TCI status of PDSCH is the same as C1, C2 and The space TCI state of the CORESET with the smallest number in the CORESET with the search space to be monitored in C3 is the same. For example, C1 has the search space to be monitored and has the smallest number, and the space TCI state of the PDSCH is TCI1.

As shown in Figure 2, C3 is also configured on symbol 3, and its spatial TCI state is TCI3, which is different from the spatial TCI state of PDSCH. Therefore, the terminal device will consider that the receiving priority of PDCCH on symbol 3 is greater than the receiving priority of PDSCH. , That is, PDCCH (the signal corresponding to C3) will be received preferentially on symbol 3. Correspondingly, the network device knows that the priority of the PDCCH is greater than the priority of the PDSCH. When the terminal device side has limited capabilities, the network device will not send the PDSCH for it on symbol 3.

The inventor found that: NR specifies the priority reception problem when PDSCH and PDCCH resources overlap in the time domain and the spatial TCI status is not the same. However, when a network device transmits one or more PDCCH and/or one or more PDSCH, and one or more When the PDCCH and one or more PDSCHs overlap in the time domain and the spatial TCI status is different, the predefined rules cannot clearly define the reception of the terminal equipment, which may lead to the reception of the physical channel by the network equipment and the terminal equipment Priorities have different understandings, which in turn leads to failures in physical channel reception.

FIG. 3 is an example diagram of determining the reception priority when the PDCCH and PDSCH resources overlap in the time domain according to an embodiment of the present application. As shown in FIG. 3, for example, PDCCH1, PDSCH1, and PDSCH2 are configured and scheduled simultaneously in a time unit (symbol 3), and two transmission points TRP1 and TRP2 are used for transmission, and PDCCH1 is transmitted in C3. Among them, C1 and C3 are associated with TRP1, and C2 is associated with TRP2. PDCCH1 is transmitted on C3 using TCI3, and PDSCH1 and PDSCH2 are transmitted by TRP1 and TRP2 using TCI1 and TCI2, respectively.

When the terminal device only has the ability to receive two different spatial TCI states, if the network device thinks that the terminal device should receive PDCCH1 and PDSCH2 first, it may not send PDSCH1; and if the terminal device preferentially receives PDCCH1 and PDSCH1, it will cause Both PDSCH1 and PDSCH2 are not received correctly.

That is, NR only specifies the priority of the TCI state (ie, the QCL parameter of PDCCH DMRS and PDSCH DMRS) between the PDCCH and PDSCH channels, and does not consider the priority in the case of multiple PDCCHs and PDSCHs. Therefore, when multiple PDCCHs and PDSCHs are transmitted at the same time and exceed the UE's receiving capability, according to the priority defined in NR, the terminal device cannot guess which physical channel the network device prefers to send, which will lead to reception errors.

In the following description, the terms "uplink control signal", "uplink control information (UCI, Uplink Control Information)", and "physical uplink control channel (PUCCH, Physical Uplink Control Channel)" can be interchanged without causing confusion. In other words, the terms "uplink data signal", "uplink data information" and "Physical Uplink Shared Channel (PUSCH)" can be interchanged;

The terms "downlink control signal", "downlink control information (DCI, Downlink Control Information)" and "physical downlink control channel (PDCCH, Physical Downlink Control Channel)" are interchangeable, and the terms "downlink data signal" and "downlink data information" It is interchangeable with "Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel)".

In addition, sending or receiving PUSCH can be understood as sending or receiving uplink data carried by PUSCH, sending or receiving PUCCH can be understood as sending or receiving uplink information carried by PUCCH; sending or receiving PDSCH can be understood as sending or receiving PDSCH carried For downlink data, sending or receiving PDCCH can be understood as sending or receiving downlink information carried by PDCCH.

The embodiments of this application may be applicable to scenarios where one or more PDCCHs or one or more PDSCHs are configured or scheduled in one scheduling unit (for example, one or more time slots, or one or more symbols); for example, it may be multiple TRPs or Multi-panel related transmission scenarios, but this application is not limited to this.

In this embodiment of the application, when multi-TRP or multi-panel operation is used, the multi-TRP or multi-panel operation related modes can be configured explicitly through high-level signaling, or implicitly configured, or involve Multiple TRP transmission schemes.

For example, multi-TRP or multi-panel operations can be explicitly configured into one or more transmission schemes, for example, transmission scheme 2 or 3, NC-JT (non-coherent joint transmission) scheme, etc.; it can also be configured by certain higher layers Parameters implicitly indicate that the terminal device can perform multi-TRP or multi-panel operations, such as the number of configured demodulation reference signal port groups (DMRS port group), the number of phase tracking reference signal (PTRS) ports, and the PDCCH transmitted at the same time The number, the number of CORESET groups, the high-level parameters configured in CORESET, etc. implicitly indicate whether the terminal device performs multi-TRP or multi-panel related operations.

For example, when the (maximum) number of DMRS port groups or the number of PTRS (maximum) ports or the (maximum) number of PDCCHs transmitted simultaneously or the number of CORESET (maximum) groups is greater than the threshold (for example, 1), or when the and The parameters related to HARQ-ACK feedback, or the parameters related to HARQ-ACK feedback configured in two or more CORESETs are different, the terminal device is determined to be multi-TRP or multi-panel operation; otherwise, the terminal device is determined to be single TRP or single panel Operation, or operation other than multi-TRP or multi-panel operation.

For another example, multi-TRP or multi-panel operation may also be a scheme involving multiple TRP transmissions, such as coordinated multi-point (CoMP), carrier aggregation (CA), and dual connectivity (DC). ),and so on.

The above is only a schematic description of the scenario of the application, but the application is not limited to this.

Embodiments of the first aspect

The embodiment of the present application provides a priority determination method, and the following line signal is taken as an example to describe first from the terminal device side. FIG. 4 is a schematic diagram of a priority determination method according to an embodiment of the present application. As shown in FIG. 4, the method includes:

401. The terminal device determines that it needs to receive at least two downlink signals in a time unit;

402. The terminal device determines the reception priority of the at least two downlink signals according to the type and/or spatial quasi co-location information of the at least two downlink signals.

It is worth noting that Figure 4 above only schematically illustrates an embodiment of the present application, but the present application is not limited thereto. For example, the order of execution between operations can be appropriately adjusted, and some other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the foregoing content, and are not limited to the description of the foregoing FIG. 4.

In some embodiments, the spatial quasi-co-location information is configured or indicated by the network device, or is predefined. The terminal device can determine that it needs to receive at least two downlink signals in a time unit (for example, a time slot) through configured or pre-configured CORESET, DCI indicated by the network device, and other information.

In some embodiments, the downlink signal includes one of the following physical signals or physical channels: physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), physical broadcast channel (PBCH), channel state information reference signal (CSI- RS), tracking reference signal (TRS), phase tracking reference signal (PTRS), synchronization signal (SS).

In some embodiments, the spatial quasi co-location (QCL) information of the physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH) or physical broadcast channel (PBCH) is the spatial quasi-co-location (QCL) information of the corresponding demodulation reference signal (DMRS). Co-location (QCL) information.

In some embodiments, the method further includes: the terminal device receives one or more downlink signals of the at least two downlink signals in the time unit according to the reception priority. For example, if three downlink signals need to be received in this time slot, but the terminal device has only the ability to receive two downlink signals with different spatial TCI states, the terminal device will receive the first two downlink signals with higher priority.

Similarly, if the terminal device only has the ability to receive a downlink signal in a different spatial TCI state, the terminal device receives the downlink signal with the highest priority. The embodiments of the present application take the limited capability of the terminal device as an example for description, but the present application is not limited to this. For example, the terminal device may only receive or transmit part of the signal or channel according to the priority even when the capability is strong.

The following is a schematic description of a situation where a time unit needs to receive a PDCCH and at least two PDSCHs.

In some embodiments, the at least two downlink signals include: a first physical downlink control channel, a first physical downlink shared channel, and a second physical downlink shared channel; the terminal device determines that the reception priority of the first physical downlink shared channel is greater than or equal to The reception priority of the second physical downlink shared channel, and the reception priority of the first physical downlink control channel is greater than or equal to the reception priority of the first physical downlink shared channel and the second physical downlink shared channel.

For example, the terminal device not only configures at least one CORESET in a time unit, but also schedules the transmission of at least 2 PDSCHs. For example, PDSCHs may be sent by different TRPs or cells, and CORESET is associated with one of the TRPs or cells. The spatial receiving capability of the terminal equipment may be limited. It cannot receive the physical channels and/or physical channels with three different spatial TCI states at the same time. It is necessary to predefine the receiving priority of multiple downlink signals, and then the terminal equipment according to its own The receiving ability (for example, the ability to receive N signals with different spatial TCI states at the same time, N is a positive integer) to receive the downlink signal with higher priority.

If the first physical downlink shared channel and the second physical downlink shared channel have the same spatial TCI state, they have the same reception priority; otherwise, the reception priority of the first physical downlink shared channel is greater than that of the second physical downlink shared channel The receiving priority. Similarly, if the first physical downlink shared channel and the first physical downlink control channel have the same spatial TCI state, they have the same reception priority; otherwise, the reception priority of the first physical downlink control channel is greater than that of the first physical downlink control channel. The reception priority of the downlink shared channel. Similarly, if the second physical downlink shared channel and the first physical downlink control channel have the same spatial TCI state, they have the same reception priority; otherwise, the reception priority of the first physical downlink control channel is greater than that of the second physical downlink control channel. The reception priority of the physical downlink shared channel.

In some embodiments, the receiving or sending priority of the first signal is greater than or equal to the receiving or sending priority of the second signal, which means that the two have the same receiving or sending priority when they have the same spatial TCI state, otherwise, The reception or transmission priority of the first signal is greater than that of the second signal.

In some embodiments, the receiving or sending priority of the first signal is greater than or equal to the receiving or sending priority of the second signal, which is equivalent to that the network device or terminal device preferentially receives or sends the first signal, and is also equivalent to the network device or terminal The device determines that the priority order of receiving or sending is the first signal and the second signal. In addition, the reception or transmission priority of the first signal is greater than or equal to the reception or transmission priority of the second signal, and the reception or transmission priority of the third signal is greater than or equal to the reception or transmission priority of the first signal and the second signal, It is equivalent to that the network device or the terminal device preferentially receives or sends the third signal and the first signal, and it is also equivalent to the network device or the terminal device determining that the priority order of receiving or sending is the third signal, the first signal, and the second signal. The first, second, or third signal includes physical channels, reference signals, control resource sets, search spaces, and so on. No specific explanation will be given later.

In some embodiments, the demodulation reference signal (DMRS) of the first physical downlink shared channel and the reference signal (RS) associated with a monitored CORESET are spatially quasi-co-located. The set of control resources to be monitored is a set of control resources associated with at least one search space to be monitored (monitored search space). For example, the set of control resources to be monitored (monitored CORESET) is the set of control resources with the lowest number among all or part of the set of control resources to be monitored configured in the nearest scheduling unit.

Among them, the scheduling unit includes a time domain unit and a frequency domain unit. The time domain unit can be a time slot (such as latest slot) or a sub-slot (such as latest subslot) or a symbol (such as latest symbol), etc.; the frequency domain unit can be activated Partial bandwidth (BWP), serving carrier, etc. The set of control resources to be monitored (monitored CORESET) is a set of control resources (CORESET) with at least one search space to be monitored (monitored search space) or at least one PDCCH candidate (PDCCH candidate) to be monitored. The associated RS is the RS associated with the QCL parameter in the CORESET TCI state or QCL indication.

For example, there are one or more monitored CORESETs, which are associated with one or more PDCCHs; one or more monitored CORESETs have the same or different TCI states. The set of control resources to be monitored (monitored CORESET) configures the search space to be monitored, including: common search space (CSS, common search space) and/or UE-specific search space (USS, UE-specific search space).

FIG. 5 is an example diagram of determining the reception priority when the PDSCH and PDSCH resources overlap in the time domain according to an embodiment of the present application. FIG. 6 is another example diagram of determining the reception priority when the PDSCH and PDSCH resources in the embodiment of the present application overlap in the time domain.

As shown in Figures 5 and 6, for example, there are two control resource sets to be monitored (monitored CORESET) in a time unit (symbol 3): C2 and C3. As shown in Figure 5, these two CORESETs can have the same TCI state, namely TCI3. When there is the same TCI state, the two CORESETs can correspond to different CORESETs of the same TRP, that is, they can be two CORESETs in a CORESET group, and can send the same PDCCH or different PDCCHs.

As shown in Figure 6, these two CORESETs can have different TCI states, namely TCI3 and TCI4. When having different TCI states, the two CORESETs can correspond to different TRPs, that is, they can belong to different CORESET groups. Regarding the CORESET grouping, reference may be made to the following embodiments.

As shown in FIG. 5 and FIG. 6, two monitored CORESETs are associated with one or more PDCCHs. In Figure 5, C2 and C3 have the same TCI state. C2 and C3 can be associated with the same PDCCH at the same time, or C2 and C3 can be associated with a PDCCH respectively. For example, one PDCCH carries common control information, and the other PDCCH carries UE specific control information. In Figure 6, C2 and C3 have different TCI states. C2 and C3 can be respectively associated with a PDCCH. For example, one PDCCH carries common control information or UE-specific control information of one TRP, and the other PDCCH carries another TRP. Public control information or UE-specific information.

Compared with PDSCH, one or more PDCCHs corresponding to these two CORESETs have higher priority. In addition, as shown in Figures 5 and 6, the time unit (symbol 3) simultaneously configures and schedules PDSCH1 and PDSCH2; among them, PDSCH1 and PDSCH2 are associated with C1 and C4, respectively.

As shown in Figures 5 and 6, the TCI status of C1 is TCI1, and the TCI status of C4 is TCI2. If the time offset between PDSCH1 and PDSCH2 and their scheduled DCI is less than a certain threshold, the corresponding TCI status can be determined to be TCI1 and respectively. TCI2. In addition, because C1 has the lowest number in all the control resource sets to be monitored configured in the nearest scheduling unit (the nearest time slot), the reception priority of PDSCH1 is greater than PDSCH2.

In some embodiments, part of the set of control resources to be monitored includes: at least one set of control resources to be monitored in a set of control resource sets explicitly configured or indicated by the network device through high-level signaling or physical layer signaling, or , At least one set of control resources to be monitored in a predefined set of control resources, or a set of control resources in a set of control resources implicitly determined by a network device through high-level signaling or physical layer signaling configuration or instructed parameters At least one set of control resources to be monitored.

For example, in order to distinguish the control channels and data channels sent by multiple TRPs, CORESET can be divided into groups with the same number of TRP or cells or TRP groups or cell groups, and each group is associated with a TRP or cell or TRP group or cell. Corresponding to the group. The CORESET grouping can be explicit or implicit. For example, N groups of CORESETs can be explicitly configured (N is greater than or equal to 2), and each group of CORESETs contains at least one CORESET; for another example, CORESETs can be grouped implicitly through predefined rules, and can also be grouped according to high-level signaling or The physical layer signaling configuration or indicated parameters implicitly determine the CORESET packet.

Taking implicit grouping as an example, CORESETs can be implicitly grouped through predefined rules.

In some embodiments, the predefined set of control resource sets is composed of odd-numbered control resource sets, or is composed of even-numbered control resource sets, or is composed of control resource sets configured on at least one symbol.

For example, CORESETs with odd CORESET ID numbers form a CORESET group, and CORESETs with even CORESET ID numbers form a CORESET group; you can also implicitly group CORESETs according to the time-domain symbols of the configured search space, for example, configure CORESETs The search space of the time domain symbol number belongs to the set S (S contains the number of one or more time domain units, and the unit of the number is a symbol, a time slot, etc.) to form a group of CORESETs.

Taking implicit grouping as an example, the grouping of CORESET can also be implicitly determined according to parameters configured or indicated by high-level signaling or physical layer signaling.

In some embodiments, the implicitly determined set of control resource sets includes: a control resource set whose high-level parameter associated with hybrid automatic repeat feedback (HARQ-ACK) in the CORESET configuration is a specific value, or the CORESET configuration One of the parameters is a set of control resources with a specific value.

For example, CORESET can be implicitly grouped according to the high-level parameters configured in CORESET. For example, each CORESET is configured with a codebook related to HARQ feedback, and CORESETs configured with the same number are implicitly grouped into one group. For another example, it is also possible to implicitly group CORESETs with the same parameter value into a group based on other high-level parameters configured inside CORESET, such as the parameters configured under the high-level parameter ControlResourceSet. Here, the CORESET grouping can correspond to the aforementioned CORESETs to be monitored.

For another example, you can also configure the same TCI state for each group of CORESET according to the explicitly or implicitly configured CORESET group, that is, configure the TCI state through RRC signaling, and activate one of the TCI states through MAC-CE signaling. The CORESETs in a group of CORESET have the same TCI state.

The CORESET grouping has been schematically described above, but the application is not limited to this.

In some embodiments, part of the control resource set to be monitored includes the control resource set of the first physical downlink control channel. Therefore, for example, by defining the CORESET to be monitored, the PDSCH and the priority received CORESET correspond to the same TRP or cell.

For example, CORESET can be explicitly or implicitly grouped to associate it with one or more TRPs or cells, and the CORESET and PDSCH that are preferentially received are associated with the same TRP or TRP group. In this way, when multiple TRPs are performing independent scheduling, when a TRP learns that other TRPs have configured CORESET to transmit PDCCH in a certain time unit, it will avoid scheduling its own PDSCH in the same time unit to prevent terminal equipment from receiving PDSCH reception failure caused by insufficient capacity.

In some embodiments, part of the control resource set to be monitored does not include the control resource set of the first physical downlink control channel. Therefore, for example, by defining the CORESET to be monitored, the PDSCH and the preferentially received CORESET correspond to different TRPs or cells.

For example, CORESET can be explicitly or implicitly grouped to be associated with one or more TRPs or cells, and the CORESET and PDSCH that are preferentially received are associated with different TRPs or TRP groups. In this way, in the same time unit, the terminal device can simultaneously receive the physical control channel and/or the physical data channel sent by multiple TRPs, thereby increasing the data transmission rate.

For another example, CORESET can be explicitly or implicitly divided into two groups: group a and group b; the control resource set where the first physical downlink control channel is located belongs to group a, and the part of the control resource set to be monitored belongs to group a. b.

In some embodiments, the first physical downlink shared channel is scheduled by a second physical downlink control channel (PDCCH) sent through a specific set of control resources.

For example, if PDSCH1 is scheduled by PDCCH2, and the PDCCH2 is sent by a specific CORESET or CORESET group, it can be determined that the reception priority of PDSCH1 is greater than or equal to the reception priority of PDSCH2. Thus, for example, the PDSCH sent by one of the TRPs can be preferentially received, and the TRP is, for example, a master TRP or a master cell or a TRP or cell connected to the UE.

In some embodiments, the specific control resource set (CORESET) includes: at least one control resource set in a group of control resource sets explicitly configured or instructed by the network device through high-level signaling or physical layer signaling, or a preset At least one control resource set in a defined set of control resources, or at least one control resource set in a set of control resources implicitly determined by a network device through a parameter configured or indicated by high-level signaling or physical layer signaling .

For example, N groups of CORESETs can be explicitly configured (N is greater than or equal to 2), and each group of CORESETs contains at least one CORESET; for another example, CORESETs can be grouped implicitly through predefined rules, or according to high-level signaling or The physical layer signaling configuration or indicated parameters implicitly determine the CORESET packet.

For example, CORESET can be implicitly grouped according to the high-level parameters configured in CORESET. For example, each CORESET is configured with a codebook related to HARQ feedback, and CORESETs configured with the same number are implicitly grouped into one group. For another example, it is also possible to implicitly group CORESETs with the same parameter value into a group based on other high-level parameters configured inside CORESET, such as the parameters configured under the high-level parameter ControlResourceSet. Here, the CORESET grouping can correspond to the aforementioned specific CORESETs.

In some embodiments, the downlink control information (DCI) corresponding to the first physical downlink shared channel indicates the transmission configuration indication (TCI) status of the first physical downlink shared channel, or the first physical downlink shared channel has an indication The transmission configuration indication (TCI) status of the

For example, if the DCI1 corresponding to PDSCH1 indicates the TCI status of the PDSCH1, but the DCI2 corresponding to PDSCH2 does not indicate the TCI status of the PDSCH2, it can be determined that the reception priority of PDSCH1 is greater than or equal to the reception priority of PDSCH2.

Thus, for example, when one or more PDSCHs in multiple PDSCHs have the default TCI state, and one or more PDSCHs have the TCI state indicated by the DCI, the PDSCH with the TCI state indicated by the DCI can be received preferentially, with the default TCI state. The status PDSCH may not actually be sent.

In the following, the situation that a time unit needs to receive at least two PDSCHs is schematically illustrated, wherein there may be no PDCCH transmission in this time unit.

In some embodiments, the at least two downlink signals include: a first physical downlink shared channel and a second physical downlink shared channel; the terminal device determines that the reception priority of the first physical downlink shared channel is greater than or equal to that of the second physical downlink shared channel. Receive priority.

In some embodiments, the demodulation reference signal (DMRS) of the first physical downlink shared channel and the reference signal (RS) associated with a monitored CORESET are spatially quasi-co-located. The set of control resources to be monitored is a set of control resources associated with at least one search space to be monitored (monitored search space) or at least one PDCCH candidate (candidate) to be monitored. For example, the set of control resources to be monitored (monitored CORESET) is the set of control resources with the lowest number among all or part of the set of control resources to be monitored configured in the nearest scheduling unit.

Among them, the scheduling unit includes a time domain unit and a frequency domain unit. The time domain unit can be a time slot (such as latest slot) or a sub-slot (such as latest subslot) or a symbol (such as latest symbol), etc.; the frequency domain unit can be activated Partial bandwidth (BWP), serving carrier, etc. The CORESET to be monitored is a CORESET with a monitored search space. The associated RS is the RS associated with the QCL parameter in the CORESET TCI state or QCL indication.

FIG. 7 is an example diagram of determining the reception priority when the PDSCH and PDSCH resources overlap in the time domain according to an embodiment of the present application. As shown in Figure 7, for example, PDSCH1 and PDSCH2 are configured and scheduled simultaneously in a time unit (such as symbol 3); among them, PDSCH1 and PDSCH2 are respectively associated with C1 and C2, that is, the TCI state of PDSCH1 and the spatial TCI state of C1 Similarly, the spatial TCI state of PDSCH2 is the same as the TCI state of C2.

As shown in Figure 7, the spatial TCI state of C1 is TCI1, and the spatial TCI state of C2 is TCI2; if the offset between PDSCH1 and PDSCH2 and the DCI that schedule them is less than a specific threshold, the spatial TCI of PDSCH1 and PDSCH2 can be determined The states are TCI1 and TCI2 respectively. In addition, since C1 has the lowest number in all the control resource sets to be monitored configured in the nearest scheduling unit, the reception priority of PDSCH1 is greater than PDSCH2.

For example, in order to distinguish the control channels and data channels sent by multiple TRPs, CORESET can be divided into groups with the same number of TRP or cells or TRP groups or cell groups, and each group is associated with a TRP or cell or TRP group or cell. Corresponding to the group. The CORESET grouping can be explicit or implicit. For example, N (N greater than or equal to 2) groups of CORESETs can be explicitly configured, and each group of CORESETs contains at least one CORESET. For another example, CORESETs can be grouped implicitly through predefined rules, and CORESETs can be implicitly determined according to parameters configured or indicated by high-level signaling or physical layer signaling.

For example, CORESET can be implicitly grouped according to the high-level parameters configured in CORESET. For example, each CORESET is configured with a codebook related to HARQ feedback, and CORESETs configured with the same number are implicitly grouped into one group. For another example, it is also possible to implicitly group CORESETs with the same parameter value into a group based on other high-level parameters configured inside CORESET, such as the parameters configured under the high-level parameter ControlResourceSet. The CORESET group can correspond to the aforementioned CORESETs to be monitored.

For example, if PDSCH1 is scheduled by PDCCH2, and the PDCCH2 is sent by a specific CORESET, it can be determined that the reception priority of PDSCH1 is greater than or equal to the reception priority of PDSCH2. Thus, for example, the PDSCH sent by one of the TRPs can be preferentially received, and the TRP is, for example, a master TRP or a master cell or a TRP or cell connected to the UE.

In some embodiments, the downlink control information (DCI) corresponding to the first physical downlink shared channel indicates the transmission configuration indication (TCI) state of the first physical downlink shared channel.

In some embodiments, the time unit may be one symbol, or more than one symbol, or one time slot, or one sub-slot, or more than one time slot, and so on.

The above illustrates schematically the situation where one time unit needs to receive at least two PDSCHs, and the PDCCH may not be received in this time unit. When the processing capability of the terminal device is low, for example, when it cannot receive two physical channels in different spatial TCI states at the same time, or when there is no PDCCH transmission, the reception priority of the physical channel is defined for it.

In some embodiments, the at least two downlink signals include: a first physical downlink control channel, a second physical downlink control channel, and a first physical downlink shared channel; the terminal device determines the first physical downlink control channel and the second physical downlink The receiving priority of the control channel is greater than or equal to the receiving priority of the first physical downlink shared channel.

In some embodiments, the at least two downlink signals include: a first physical downlink control channel, a second physical downlink control channel, a first physical downlink shared channel, and a second physical downlink shared channel; the terminal device determines the first physical downlink The reception priority of the control channel and the second physical downlink control channel are both greater than or equal to the reception priority of the first physical downlink shared channel and the second physical downlink shared channel.

In some embodiments, the at least two downlink signals include: a first physical downlink shared channel, a second physical downlink shared channel, and a downlink reference signal; the terminal device determines that the first physical downlink shared channel and the second physical downlink shared channel The receiving priority is greater than or equal to the receiving priority of the downlink reference signal.

Therefore, by determining the priority, the network device and the terminal device can have a consistent understanding of the priority of the TCI state. The network device may send physical channels and/or physical signals according to the receiving capability of the terminal device, and not send physical channels and/or physical signals that exceed the receiving capability of the terminal, saving resources and transmission power. However, the terminal device can correctly receive the physical channel and/or physical signal sent by the network device under the limited receiving capability, so as to avoid incorrectly receiving the untransmitted physical channel and/or physical signal.

The above is a schematic description from the terminal device side, and the following description will be made in conjunction with the network device side, and the same content as the above embodiment will not be repeated.

FIG. 8 is another schematic diagram of a priority confirmation method according to an embodiment of the present application. As shown in FIG. 8, the method includes:

801: The network device determines that at least two downlink signals need to be sent in a time unit;

802. The network device determines the transmission priority of the at least two downlink signals according to the types and/or spatial quasi co-location (QCL) information of the at least two downlink signals.

805. The network device sends one or more downlink signals to the terminal device in the time unit.

It should be noted that Fig. 8 above only schematically illustrates the embodiments of the present application, but the present application is not limited thereto. For example, the order of execution between operations can be appropriately adjusted, and some other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description of FIG. 8 above.

The above embodiments only exemplify the embodiments of the present application, but the present application is not limited thereto, and appropriate modifications may also be made on the basis of the above various embodiments. For example, each of the above embodiments may be used alone, or one or more of the above embodiments may be combined.

It can be seen from the foregoing embodiment that when at least two signals need to be received or transmitted in a time unit, the reception or transmission of the at least two signals is determined according to the type of the at least two signals and/or the spatial quasi co-location information. Send priority. As a result, the sender and receiver can agree on the priority of at least two signals, reducing or even avoiding signal reception errors.

Embodiments of the second aspect

The embodiment of the present application provides a method for receiving a downlink signal, which is described from a terminal device. The embodiments of the present application can be combined with the embodiments of the first aspect, or can be implemented separately, and the same content as the embodiments of the first aspect will not be repeated.

In some embodiments, the downlink signal receiving method includes: a terminal device needs to receive at least two downlink signals in a scheduling unit, and the terminal device does not expect the resources of at least two downlink signals to overlap in a time unit, or, The terminal device determines that the resources of at least two downlink signals do not overlap in a time unit.

In some embodiments, the downlink signal receiving method includes: a terminal device needs to receive at least two downlink signals in a scheduling unit, and the terminal device does not expect to have different spatial quasi co-location (QCL) information in a time unit. The resources of at least two downlink signals overlap, or the terminal device determines that the resources of at least two downlink signals with different spatial quasi co-location (QCL) information in a time unit do not overlap.

In some embodiments, the spatial quasi-co-location information is configured or indicated by the network device, or is predefined.

In some embodiments, the at least two downlink signals include: a first physical downlink control shared channel and a first physical downlink shared channel; or, the at least two downlink signals include: a first physical downlink control channel, a first physical downlink shared channel And the second physical downlink shared channel.

For example, in the TRP scenario, the UE does not expect the PDCCH and PDSCH to overlap, that is, it does not expect PDSCH to be scheduled in the control region. In this way, it is avoided that the number of physical channels that exceed the UE's receiving capability is configured or scheduled in one time unit, thereby avoiding the UE's receiving failure due to insufficient receiving capability.

For another example, in the TRP scenario, the UE does not expect the PDCCH and PDSCHs with different TCI states to overlap in time units. Therefore, it is avoided that the PDSCH and PDCCH scheduled by the same TRP occupy too much UE receiving capacity in the same time unit, thereby avoiding the failure of receiving physical channels of other TRPs or cells.

Embodiment of the fourth aspect

The embodiment of the present application provides a priority determination method, which is described from a terminal device. The embodiments of the present application can be combined with the embodiments of the first to third aspects, or can be implemented separately, and the same content as the embodiments of the first to third aspects will not be repeated.

FIG. 11 is a schematic diagram of a priority determination method according to an embodiment of the present application. As shown in FIG. 11, the method includes:

1101. The terminal device determines that it needs to monitor at least two control resource sets (CORESET) in a time unit;

1102. The terminal device determines the monitoring priority of the at least two control resource sets (CORESET) according to the search space and/or spatial quasi co-location information configured by the at least two control resource sets (CORESET).

It is worth noting that the above Figure 11 only schematically illustrates the embodiments of the present application, but the present application is not limited thereto. For example, the order of execution between operations can be appropriately adjusted, and some other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description of FIG. 11 above.

In previous versions such as R15, for multiple CORESETs with overlapping monitoring occasions to be monitored, and multiple CORESETs have the same or different spatial TCI states, the terminal device only monitors one of the CORESET and the CORESET has other CORESETs with the same QCL typeD characteristics. If a public search space set (CSS set) is configured, the terminal device will monitor the CORESET associated with the CSS set with the lowest CSS set number in the cell with the lowest cell number in the cell containing the CSS; otherwise, the terminal device will monitor CORESET (the CORESET correspondings to the CSS set with the lowest index in the cell with the lowest index containing CSS, if any; otherwise, to the) associated with the USS set with the lowest USS set number in the cell with the lowest cell number USS set with the lowest index in the cell with lowest index).

In a multi-TRP or multi-panel scenario, multiple TRPs or panels or cells simultaneously transmit for the terminal device, and the receiving capability of the terminal device will be enhanced accordingly. For example, the terminal device can receive two beams in different directions at the same time, that is, it can receive two or more physical channels or physical signals with different spatial TCI states at the same time. Different terminal devices have different receiving capabilities. For example, when the receiving capabilities of the terminal device are exceeded, the monitoring priority of each search space needs to be determined.

For ease of description, here it is only assumed that the terminal device is working on a cell or an active bandwidth part, and the application is not limited to this. For example, when a terminal device works on multiple cells, it can be extended accordingly according to the R15 protocol. For example, the CSS set or USS set is defined as the CSS set or USS set on a cell with a low cell index including CSS or USS, etc. .

In some embodiments, the at least two control resource sets (CORESET) include: a first control resource set (CORESET) configured with a UE-specific search space set (USS set), and a first control resource set (CORESET) configured with a UE-specific search space set (USS set) A second control resource set (CORESET) and a third control resource set (CORESET) configured with a common search space set (CSS set);

The terminal device determines that the monitoring priority of the first control resource set (CORESET) is greater than or equal to the monitoring priority of the second control resource set (CORESET), and the monitoring priority of the third control resource set (CORESET) is greater than or equal to the first control resource The monitoring priority of the set (CORESET) and the second control resource set (CORESET).

For example, the first control resource set (CORESET) configured with the UE specific search space set (USS set) and the third control resource set (CORESET) configured with the common search space set (CSS set) may be the same control resource set ( CORESET), that is, the first CORESET and the third CORESET are the same CORESET, or the first CORESET and the third CORESET have the same spatial TCI state. In these cases, the first control resource set (CORESET) configured with the UE specific search space set (USS set) and the third control resource set (CORESET) configured with the common search space set (CSS set) have the same priority . In addition, the third CORESET has a higher priority than the first CORESET.

Similarly, if the second CORESET and the third CORESET are the same CORESET or both have the same spatial TCI state, they have the same priority; otherwise, the third CORESET has a higher priority than the second CORESET. Similarly, if the first CORESET and the second CORESET are the same CORESET or both have the same spatial TCI state, they have the same priority; otherwise, the first CORESET has a higher priority than the second CORESET.

For example, the terminal device preferentially monitors the CORESET corresponding to the public search space (CSS) (called CSS CORESET) and the CORESET corresponding to a UE-specific search space (USS) (called USS CORESET), and has the same priority as the CORESET received by priority. CORESET of the space TCI state. For another example, when the terminal device is configured to perform TRP related operations, if the terminal has the ability to receive two signals with different spatial TCI status at the same time, the terminal device will monitor the CORESET corresponding to the CSS set and the corresponding USS set with different spatial TCI states CORESET.

In some embodiments, the first control resource set is the control resource set with the lowest number and configured with a UE-specific search space (USS) among the multiple (for example, all) control resource sets to be monitored configured in the most recent scheduling unit . For example, the USS CORESET is the CORESET corresponding to the UE-specific search space (USS) with the lowest number.

Therefore, the monitoring priority of the UE is defined to ensure that both the base station and the UE have a consistent understanding of the search space and CORESET that can be monitored. The base station and the UE can only send and receive control information in the search space and CORESET that the UE has the ability to monitor, avoiding unnecessary power and resource loss.

In some embodiments, the first control resource set (CORESET) is the control resource set with the lowest number among the partial control resource sets to be monitored configured in the most recent scheduling unit, wherein the partial control resource set to be monitored includes the The third control resource collection.

For example, the USS CORESET is the CORESET with the lowest number among the part of the CORESETs to be monitored, and the CSS CORESET is also included in the part of the CORESETs to be monitored. Or, the TCI state of the USS CORESET is the same as the TCI state of the CSS CORESET.

As a result, CORESET can be grouped explicitly or implicitly to associate it with one or more TRPs or cells, and the CORESET corresponding to the priority-monitored USS and the CORESET corresponding to the priority-monitoring CSS are the same TRP or Associated with TRP group. In this way, when multiple TRPs are performing independent scheduling, when a TRP learns that other TRPs are configured with CSS and CORESET in a certain time unit to transmit common control information, it will avoid sending its own UE-specific control information in the same time unit. , To avoid PDSCH reception failure caused by insufficient reception capability of the terminal equipment.

In some embodiments, the first control resource set (CORESET) is the control resource set with the lowest number among the partial control resource sets to be monitored configured in the most recent scheduling unit, wherein the partial control resource set to be monitored does not include The third set of control resources.

For example, CORESET can be explicitly or implicitly divided into two groups: group a and group b; the third control resource set belongs to group a, and the part of the control resource set to be monitored belongs to group b.

For example, the USS CORESET is the CORESET with the lowest number among the part of the CORESETs to be monitored, and the CSS CORESET is not included in the part of the CORESETs to be monitored. Or, the TCI state of the USS CORESET is different from the TCI state of the CSS CORESET.

As a result, CORESET can be grouped explicitly or implicitly to associate it with one or more TRPs or cells, and the CORESET corresponding to the priority monitored USS and the CORESET corresponding to the priority monitoring CSS are different from the TRP or Associated with TRP group. In this way, in the same time unit, the terminal device can receive control information sent by multiple TRPs at the same time.

In some embodiments, the at least two control resource sets (CORESET) include: a first control resource set (CORESET) configured with a UE-specific search space (USS) and a second control resource configured with a UE-specific search space (USS) Set (CORESET); the terminal device determines that the monitoring priority of the first control resource set (CORESET) is greater than or equal to the monitoring priority of the second control resource set (CORESET).

For example, if the first CORESET and the second CORESET are the same CORESET or both have the same spatial TCI state, they have the same priority; otherwise, the first CORESET has a higher priority than the second CORESET.

In some embodiments, the multiple control resource sets configured in the most recent scheduling unit are divided into at least two groups, and each group of resource control sets is configured with the same transmission configuration indication (TCI) state; the part of the control to be monitored The resource set is one of the at least two groups.

In some embodiments, the CSS may be one or more, associated with one or more CORESET groups; one or more CSSs have the same or different TCI states. Regarding the CORESET grouping, reference may be made to the embodiment of the first aspect.

In some embodiments, in addition to preferentially receiving the CORESETs determined above, CORESETs with the same QCL-TypeD characteristics as the aforementioned CORESETs can also be preferentially received.

It can be seen from the above embodiment that when at least two control resource sets (CORESET) need to be monitored in a time unit, the at least two control resources are determined according to the search space configured by the at least two control resource sets (CORESET) The monitoring priority of the collection (CORESET). Thus, the terminal device can monitor at least two control resource sets (CORESET).
