Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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.

Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture according to an embodiment of the present invention. As shown in fig. 1, the UE includes a user terminal 11 and a base station 12, where the user terminal 11 may be a UE, for example: the terminal side Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID, Mobile Internet Device), or a Wearable Device (Wearable Device), and it should be noted that the specific type of the user terminal 11 is not limited in the embodiments of the present invention. The base station 12 may be a base station of 5G and later releases (e.g., a gNB, a 5G NR NB), or a base station in other communication systems, or referred to as a node B, and it should be noted that, in the embodiment of the present invention, only the 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

It should be noted that the specific functions of the user terminal 11 and the base station 12 are described in detail through a plurality of embodiments below.

Fig. 2 is a flowchart illustrating a method for transmitting a synchronization signal block according to an embodiment of the present invention. The method is applied to network side equipment, and comprises the following steps:

step 210, if the SSB and the CORESET #0 have an association relationship, transmitting a unicast physical downlink control channel (unicast PDCCH) or a unicast physical downlink shared channel (unicast PDSCH) on a symbol for transmitting the SSB.

For example, if the SSB and CORESET #0 have an association relationship, a unique PDCCH is simultaneously transmitted on a symbol on which the SSB is transmitted, or a unique PDSCH is simultaneously transmitted on a symbol on which the SSB is transmitted. The following method for multiplexing other channels and SSBs on the same symbol for transmission is similar to this, and can achieve simultaneous transmission, which is not described again.

Currently, in the beamforming technology, a network side device transmits an SSB through a beam to perform beam measurement, where the SSB includes a synchronization signal and a Physical Broadcast Channel (PBCH). Since the network side device broadcasts and sends the SSB on the beams in different spatial domain transmission directions in a polling manner, in order to ensure reliable data transmission between the network side device and the UE, only common information can be transmitted on the symbols transmitting the SSB, and other dedicated information cannot be transmitted, for example, a unicast Physical Downlink Control Channel (unicast PDCCH) results in waste of bandwidth resources.

In order to make full use of bandwidth resources and improve the utilization rate of the frequency band, the network side device may determine whether to transmit other channels on the symbol transmitting the SSB according to whether the SSB is configured to have an association relationship with the CORESET # 0.

In the embodiment of the present invention, SSB and CORESET #0 have an association relationship that SSB and CORESET #0 are Quasi co-located (QCL).

Preferably, an association exists between SSB and CORESET #0 such that SSB and CORESET #0 are spatially QCL.

If the SSB and the CORESET #0 are spatial QCL, that is, the SSB and the CORESET #0 have the same spatial domain transmission direction (transmission on the same beam can be achieved), in this case, the network side device may transmit other dedicated information on the symbol on which the SSB is transmitted, for example, a unicast Physical Downlink Shared Channel (unicast PDSCH) or a unicast PDCCH on the symbol on which the SSB is transmitted.

Specifically, first, the network side device configures configuration information of the SSB, where the configuration information of the SSB at least includes: usage of SSB (for performing beam measurement, Radio Link Monitoring (RLM) measurement, etc.), SSB Measurement Time Configuration (SMTC) window, and SSB resource information.

It should be noted that, the network side device may configure 64 SSBs at most.

Secondly, the network side device configures configuration information of the core set #0 through a dedicated signaling, wherein the configuration information of the core set #0 includes: a Transmission Configuration Indication state (TCI state).

In the embodiment of the invention, the network side equipment configures a TCI state for the CORESET #0 through a dedicated signaling, wherein the TCI state is used for configuring and indicating QCL information of the CORESET #0, and a source Reference Signal (source RS, source Reference Signal) in the TCI state is SSB.

The source RS in the TCI state configured for core set #0 by the network side device is SSB, which means that SSB and core set #0 are at least spatial QCL, i.e. SSB and core set #0 have an association relationship.

It should be noted that the dedicated signaling may be RRC signaling or other higher layer signaling, and is not limited in this respect.

Finally, the network side device determines whether to transmit other special information on the symbol for transmitting the SSB based on whether the SSB and the CORESET #0 are configured to have an association relationship.

The following details a specific case that the network side device determines whether to transmit other dedicated information on the symbol for transmitting SSB based on whether there is an association relationship between SSB and CORESET # 0:

first, if SSB and CORESET #0 have an association relationship, for example, SSB and CORESET #0 are spatial QCL, a unique PDCCH or a unique PDSCH is transmitted on a symbol where SSB is transmitted.

(a) And multiplexing the unique PDCCH and the SSB in CORESET #0 on the same symbol for transmission, wherein the unique PDCCH and the SSB in CORESET #0 are of spatial QCL.

All the unique PDCCHs in the CORESET #0 have the same QCL information, and since the SSB and the CORESET #0 are spatial QCLs, the unique PDCCHs in the CORESET #0 can be transmitted on symbols on which the SSB is transmitted.

(b) Multiplexing the non-physical PDSCH and the SSB on the same symbol for transmission, wherein the non-physical PDSCH is scheduled by DCI carried in the PDCCH, and the TCI state in the DCI indicates that the non-physical PDSCH and the SSB are of a spatial QCL.

It should be noted that the DCI scheduling the unicast PDSCH is not limited to be carried by the PDCCH in CORESET #0, and may also be carried by a PDCCH in another CORESET, for example, the DCI carried by the PDCCH in CORESET #1, and is not limited in this regard.

When the DCI scheduled non-physical PDSCH and the SSB are spatial QCLs, the DCI scheduled non-physical PDSCH may be transmitted on a symbol on which the SSB is transmitted.

Second, for the SSB used for beam measurement or RLM measurement, if there is no correlation between the SSB and CORESET #0, the SSB is not transmitted on the same symbol as other channel multiplexes within the SMTC window on the beam on which the SSB is located.

If there is no correlation between SSB and CORESET #0, it means that SSB and CORESET #0 do not have the same spatial domain transmission direction, so in order to ensure effective transmission and effective reception of SSB for beam measurement or RLM measurement, SSB is not transmitted on the same symbol multiplexed with other channels within the SMTC window on the beam where SSB is located.

Thirdly, if there is no correlation between the SSB and the CORESET #0 for the SSB other than the beam measurement or the RLM measurement, the uniform PDCCH and the SSB are multiplexed and transmitted on the same symbol when the SSB and the uniform PDCCH are spatial QCL.

The unique PDCCH indicates a unique PDCCH that is a spatial QCL with SSB in the CORESET other than CORESET # 0.

For SSBs other than beam measurement or RLM measurement, if there is no association between the SSBs and the CORESET #0 and the SSBs and the unicast PDCCH are not spatial QCLs, priority transmission of the SSBs or the unicast PDCCH may be achieved by configuring or presetting priority.

Fourthly, for SSBs other than beam measurement or RLM measurement, if there is no association between the SSBs and CORESET #0, if the SSBs and the unique PDSCH are spatial QCLs, the unique PDSCH and the SSBs are multiplexed and transmitted on the same symbol.

The unique PDSCH scheduled by the DCI is guaranteed to be spatial QCL with the SSB.

For other SSBs except for beam measurement or RLM measurement, if there is no association between the SSB and CORESET #0 and the SSB and the unicast PDSCH are not spatial QCLs, priority transmission of the SSB or the unicast PDSCH may be performed by configuring or presetting priority.

According to the technical scheme disclosed by the embodiment of the invention, if the SSB and the CORESET #0 have an incidence relation, the network side equipment transmits a unique PDCCH or a unique PDSCH on a symbol for transmitting the SSB, so that the frequency band utilization rate can be effectively improved.

Fig. 3 is a flowchart illustrating another synchronization signal block transmission method according to an embodiment of the present invention. The method is applied to the terminal equipment and comprises the following steps:

step 310, receiving configuration information, wherein the configuration information is used for indicating that an association relationship exists between the SSB and the CORESET # 0.

And step 320, receiving a unique PDCCH or a unique PDSCH on the symbol receiving the SSB.

In the embodiment of the present invention, SSB and CORESET #0 have an association relationship that SSB and CORESET #0 are QCL.

Preferably, an association exists between SSB and CORESET #0 such that SSB and CORESET #0 are spatial QCLs.

In the embodiment of the present invention, the configuration information includes: configuration information of the SSB and configuration information of CORESET #0, wherein the configuration information of CORESET #0 is configured by the network side equipment through special signaling;

configuration information for core set #0 includes: and the TCI state is used for configuring and indicating QCL information of CORESET #0, and the source RS in the TCI state is SSB.

After receiving the configuration information sent by the network side device, the UE may determine that the SSB and the CORESET #0 are spatial QCL if it determines that the source RS in the TCI state of the CORESET #0 is SSB according to the configuration information.

After the UE determines that the SSB and CORESET #0 are spatial QCLs, it determines on which beam to receive the control channel according to the beam information (spatial reception parameters) in the TCI state of CORESET #0, and then receives the SSB on the beam, and receives the uni-est PDCCH or the uni-est PDSCH on the symbol on which the SSB is received.

In another embodiment of the present invention, if the network side device reconfigures the TCI state of the core set #0, the parameter information of the search space #0 in the core set #0 is determined according to the reconfigured TCI state, where the parameter information of the search space #0 is used to indicate a common search space for monitoring the Type 0-PDCCH.

The core space #0 comprises one or more search spaces, and if the network side device reconfigures the TCI state of the core space #0 and the network side device configures DCI on the core space #0 to schedule a non-actual PDSCH transmission or transmit UE-specific information (e.g., UE specific PDCCH) on the core space #0, the UE first determines the parameter information of the core space #0 in the core space #0 according to the reconfigured TCI state of the core space #0, and then monitors the common search space of the Type0-PDCCH according to the parameter information.

In the embodiment of the present invention, receiving a unique PDCCH on a symbol receiving an SSB includes:

on a symbol for receiving the SSB, a unique PDCCH in the CORESET #0 is received, wherein the unique PDCCH and the SSB in the CORESET #0 are QCL.

When the UE receives the configuration information sent by the network side device and indicating that SSB and CORESET #0 are spatial QCLs, the UE determines on which beam to receive the control channel according to the beam information indicated by the TCI state of CORESET #0, for example, indicating on which beam the SSB is located, and further receiving the SSB on the beam, and receiving the unicast PDCCH in CORESET #0 on the symbol on which the SSB is received.

In the embodiment of the present invention, receiving a unicast PDSCH on a symbol receiving an SSB includes:

and receiving a non-idle PDSCH on a symbol for receiving the SSB, wherein the non-idle PDSCH is scheduled by the DCI, and the non-idle PDSCH and the SSB are QCL.

When the UE receives the configuration information sent by the network side device and indicating that SSB and CORESET #0 are spatial QCLs, the UE determines on which beam to receive the control channel according to the beam information indicated by the TCI state in the DCI, for example, indicating on which beam the SSB is located, and then receiving the SSB on the beam, and receiving the unicast PDSCH on a symbol for receiving the SSB, where the unicast PDSCH is scheduled by the DCI.

It should be noted that the DCI scheduling the unicast PDSCH is not limited to the DCI carried by the PDCCH in CORESET #0, and may also be the DCI carried by the PDCCH in another CORESET, and is not specifically limited herein.

The UE receives configuration information for indicating that the SSB and the CORESET #0 have an association relationship, and then receives the SSB on a beam where the SSB is located and receives a non-uniform PDCCH or a non-uniform PDSCH on a symbol for receiving the SSB according to the configuration information, so that the frequency band utilization rate can be effectively improved.

Fig. 4 is a flowchart illustrating another synchronization signal block transmission method according to an embodiment of the present invention. The method is applied to the terminal equipment and comprises the following steps:

and step 410, receiving configuration information, wherein the configuration information is used for indicating that no association exists between the SSB and the CORESET #0, and the SSB is used for performing beam measurement or RLM measurement.

At step 420, within the SMTC window, an SSB is received.

After receiving the configuration information sent by the network side device and used for indicating that the SSB and the CORESET #0 do not have an association relationship, the UE may determine that the SSB and the CORESET #0 do not have the same spatial domain transmission direction, and therefore, the UE receives the SSB used for performing beam measurement or RLM measurement in the SMTC window on the beam where the SSB is located.

And the UE receives configuration information for indicating that the SSB and the CORESET #0 have no association relationship, and further effectively receives the SSB for beam measurement or RLM measurement in an SMTC window on a wave beam where the SSB is located according to the configuration information.

Fig. 5 is a flowchart illustrating another method for transmitting a synchronization signal block according to an embodiment of the present invention. The method is applied to the terminal equipment and comprises the following steps:

Step 520, receive a unicast PDCCH on the symbol on which the SSB is received.

For other SSBs configured by the network side device for performing beam measurement and RLM measurement, after the UE receives configuration information indicating that the SSB and the CORESET #0 do not have an association relationship and the SSB and the unique PDCCH are QCL, the SSB is received on a beam where the SSB is located, and the unique PDCCH is received on a symbol where the SSB is received, so that the frequency band utilization rate can be effectively improved.

For other SSBs configured by the network side device for performing beam measurement and RLM measurement, after the UE receives configuration information indicating that the SSB and the CORESET #0 do not have an association relationship and the SSB and the uniform PDCCH are not spatial QCLs, the UE may preferentially receive the SSB or preferentially receive the uniform PDCCH according to a configuration or a preset priority.
