Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, and in particular to a resource notification method and device and storage medium. BACKGROUND

[0002] For satellite communication scenarios and ground millimeter wave communication scenarios, a cell increases the receiving performance of the uplink and downlink of a user by introducing narrow beams. The narrow beam is a narrower beam relative to an omnidirectional beam covering the entire cell. Since a single narrow beam can only cover part of the area of a cell, the cell needs to support multiple narrow beams to complete the scanning of the entire cell coverage area. Different narrow beams scan different ground areas.

[0003] For ground communication scenarios, in the case of a cell operating in a frequency band above 6 GHz, since the operating frequency of the frequency point is low, the path transmission loss of the frequency is relatively small compared to the high frequency band. The base station can use an omnidirectional wide beam to cover the entire cell. When a terminal device (User Equipment, UE) moves within the cell, it does not need to perform beam switching. In the case of a cell operating in a millimeter wave frequency band above 6 GHz, such as above 20 GHz, since the operating frequency of the frequency point is high, the path transmission loss of the frequency is large. If a wide beam is still used, the distance covered by the beam is short and does not meet the networking requirements. Therefore, narrow beams need to be introduced to complete the scanning of the entire cell by multiple narrow beams in different directions.

[0004] For satellite communication scenarios, the coverage area radius of a single satellite on the ground reaches several hundred or even thousands of kilometers, much larger than the coverage radius of several hundred meters of a ground cell. The coverage area of a satellite cell on the ground is large enough to use a wide beam to scan users. On the one hand, the antenna gain is low and the power consumption is large. On the other hand, due to the small number of beams, it is difficult to realize spatial division multiplexing between beams, and the user capacity supported by the cell is limited. Compared with the limitations of a wide beam, a narrow beam reduces the scanning area on the ground by reducing the beam width, on the one hand, the antenna gain is improved, and on the other hand, due to the large number of beams, the utilization of wireless resources can be improved through spatial division multiplexing between beams, and the user capacity of the satellite cell can be increased. Therefore, a satellite cell also needs to introduce a narrow beam to complete the scanning of the entire cell through multiple narrow beams in different directions. In the satellite communication scenario, the scanning area of a beam on the ground is called a wave position, and the coverage area of a cell is composed of multiple wave positions. When a cell supports multiple beams, due to the different ground areas pointed to by different beams, from the perspective of a UE, the UE measures different downlink transmission delays and frequency offsets, and different downlink channel qualities in different beams. From the perspective of a base station, the base station measures different uplink transmission delays and frequency offsets, and different uplink channel qualities of a UE in different beams. Therefore, different beams need to be configured with independent pilot signals (such as Synchronization Signal / PBCH block (SSB) signals) and channel monitoring reference signals (such as Channel State Information-Reference Signal (CSI-RS) and Sounding Reference Signal (SRS)) for monitoring the channel conditions of a UE in different beams.

[0005] In the case where a cell supports a sufficient number of narrow beams, a beam pair that satisfies the spatial isolation condition can be found from these beams. In theory, even if the two beams in the beam pair transmit downlink data in the same time-frequency resource, they will not interfere with each other. However, since the terminal does not know the beam planning of the base station, it is assumed that the other beams do not satisfy the spatial isolation condition with the current resident beam, which leads to the inability to effectively realize spatial division multiplexing of frequency resources, and reduces the resource utilization and throughput of the cell.

[0006] Specifically, TS 38331 h50 protocol mentions that the downlink beam can be marked by the resource number of SSB signal or CSI-RS signal, the resource number of SSB signal is SSB-Index, the resource number of CSI-RS signal is NZP-CSI-RS-ResourceId, and the uplink beam can be marked by the resource number of SRS signal, the resource number of SRS signal is SRS-ResourceId. In the case that the uplink beam and the downlink beam to which the UE belongs are completely overlapped, the base station simultaneously performs beam management on the uplink beam and the downlink beam according to the resource number of SSB signal or CSI-RS signal (the uplink signal can be associated with the downlink SSB signal or CSI-RS signal). In the case that the uplink beam and the downlink beam to which the UE belongs have non-overlapping parts, the base station distinguishes the uplink and downlink directions and performs beam management respectively. At present, in the satellite communication scenario and the millimeter wave communication scenario, the uplink beam and the downlink beam to which the UE belongs are completely overlapped.

[0007] TS 38213 h60 and TS 38214 h60 protocol mention that the resource position of SSB signal needs to be staggered with the resource position of physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH) and CSI-RS. The resource position of CSI-RS signal needs to be staggered with the resource position of PDCCH and PDSCH. The resource position of physical random access channel (PRACH) needs to be staggered with the resource position of physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH) and SRS.

[0008] In 5G systems, SSB signals, CSI-RS signals, Type 0 PDCCH, Type 0A PDCCH, Type 1 PDCCH, Type 2 PDCCH, System Information Block (SIB), PRACH, and SRS signals all support differentiated beam configurations. The network device notifies the UE of resource configuration information for SSB signals, Type 0 PDCCH, Type 0A PDCCH, Type 1 PDCCH, Type 2 PDCCH, SIB, and PRACH via the Master Information Block (MIB) or SIB. The UE needs to monitor these signals and channels across all beams and consider their resource locations to be occupied. CSI-RS and SRS signals are notified to the UE via user-level signaling, allowing the network device to provide different configurations to the UE, for example, allowing the UE to monitor only the CSI-RS and SRS signals of the currently active beam.

[0009] The UE monitors the SSB signals, Type 0 PDCCH, Type 0A PDCCH, Type 1 PDCCH, Type 2 PDCCH, SIB, and PRACH of all beams in the cell. Therefore, the network equipment follows the protocol provisions of the 5G system and, when configuring other signal and channel resources for the UE, staggers the resource locations of the SSB signals, Type 0 PDCCH, Type 0A PDCCH, Type 1 PDCCH, Type 2 PDCCH, SIB, and PRACH of all beams to ensure that the UE can successfully receive other signals and channels.

[0010] For CSI-RS signals and SRS signals, the UE monitors them according to the user-level resource configuration provided by the network device. The network device can allow the UE to monitor these signals only on the current resident beam and adjacent beams based on the UE location or the UE's current resident beam.

[0011] That is, the UE needs to monitor the SSB signals, Type0 PDCCH, Type0A PDCCH, Type1 PDCCH, Type2 PDCCH, SIB, PRACH of all beams of the cell, and considers that the resource positions of these signals and channels are in an occupied state. For two beams that meet the spatial isolation condition, assuming that the beams are beam 1 and beam 2, the signal and channel resource positions of beam 1 need to avoid the SSB signals, Type0 PDCCH, Type0A PDCCH, Type1 PDCCH, Type2 PDCCH, and PRACH resource positions of beam 2, which limits the resource capacity that can be used by beam 1, cannot effectively realize frequency resource space division multiplexing, and has a negative impact on the overall resource utilization and throughput of the cell.

It can be known by those skilled in the art that, with the evolution of network architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0119] In one exemplary embodiment, as shown in Figure 2 a resource notification method is provided. The method is applied to a network device and a terminal device in a wireless communication system. Figure 1The network device in the method is taken as an example for illustration, including:

[0120] S202: sending a resource notification message to the terminal device, the resource notification message being used for notifying beam information of beams that do not need to be monitored by the terminal device; resources occupied by the beams that do not need to be monitored being used for data transmission of uplink data or downlink data by the terminal device.

[0121] The network device sends a resource notification message to the terminal device, the resource notification message being used for notifying beam information of beams that do not need to be monitored by the terminal device, resources occupied by the beams that do not need to be monitored being available, and the terminal device being able to perform data transmission of uplink data or downlink data based on the resources occupied by the beams that do not need to be monitored, thus increasing the wireless resources available to users on each beam and improving the utilization rate of wireless resources and throughput of the cell.

[0122] The beam information can include a beam number, the beam number being used for uniquely determining a beam, and different beam numbers corresponding to beams with different coverage areas.

[0123] The resources occupied by the beams include at least one of resources of reference signals and resources of common channels occupied by the beams. The reference signals and the common channels are in a quasi-co-location relationship with the beams. In an embodiment, the quasi-co-location relationship can be obtained according to a Transmission Configuration Indicator (TCI) state or a Transmission Configuration Indicator-Uplink (TCI-UL) state established between the reference signals or the common channels and the beams; the TCI state is a TCI state specified in a 5G system protocol or a TCI state notified by the network device to the terminal device through wireless air interface signaling, and similarly, the TCI-UL state is a TCI state specified in a 5G system protocol or a TCI state notified by the network device to the terminal device through wireless air interface signaling.

[0124] In an embodiment, the resource notification message includes any one or both of the following two types of information: beam information of beams that do not need to be monitored; and beam information of beams that need to be monitored.

[0125] Specifically, the resource notification message can indicate which beams do not need to be monitored, for example, the resource notification message can include only beam information of beams that do not need to be monitored, or only beam information of beams that need to be monitored, or both beam information of beams that do not need to be monitored and beam information of beams that need to be monitored.

[0126] Thus, the network device can send the beam information of the beams that need to be monitored to the terminal device, or the network device sends the beam information of the beams that do not need to be monitored to the terminal device, so that the terminal device obtains the beam information of the beams that do not need to be monitored based on the beam information of the beams that need to be monitored and the beam information of all the beams in the cell, or the network device sends the beam information of the beams that need to be monitored and the beam information of the beams that do not need to be monitored to the terminal device.

[0127] In one of the embodiments, the beam information is represented by a resource number parameter of a reference signal, and the reference signal includes an SSB signal, a CSI-RS signal or an SRS signal.

[0128] The resource number parameter of the SSB signal is SSB-Index, the resource number parameter of the CSI-RS signal is NZP-CSI-RS-ResourceId in NZP-CSI-RS-ResourceSet used for beam management purposes, and the resource number parameter of the SRS signal is SRS-ResourceId in SRS-ResourceSet used for beam management purposes. The resource number in the resource number parameter of the reference signal corresponds to the beam number, and one bit of the resource number in the reference signal parameter represents one number of the beam. For example, the resource number of the reference signal has a certain order, and the beam number also has an order. When the orders of the two correspond to each other, the resource number of the corresponding bit is the corresponding beam number. It should be noted that in actual application, the beam number can not be introduced in the communication protocol, and it can be represented directly by the resource number.

[0129] In one of the embodiments, the resource notification message includes any one of the following two kinds of information: a resource number parameter of a reference signal, the resource number parameter of the reference signal being used to represent the beam information; and a bit map parameter, the bit map parameter being used to represent the beam information.

[0130] In one of the embodiments, the beam information is represented by a resource number parameter of a reference signal, and the reference signal includes an SSB signal, a CSI-RS signal or an SRS signal.

[0131] In other embodiments, the network device can send a bit map parameter to the terminal device, the bit map parameter being used to represent the beam information, the bit map being a data structure composed of multiple bits with values of 0 or 1. A bit map parameter, each bit representing a beam, indicating whether the beam needs to be monitored or not by the value of the bit, for example, a value of 1 indicating that the corresponding beam does not need to be monitored, and a value of 0 indicating that the corresponding beam needs to be monitored, in other embodiments, a value of 0 indicates that the corresponding beam does not need to be monitored, and a value of 1 indicates that the corresponding beam needs to be monitored, which is not specifically limited here. The number of bits of the bit map parameter is the same as the number of beams corresponding to the beam information. For example, in the case where the beam information is represented by the resource number parameter of the reference signal, the number of bits of the bit map parameter is the same as the number of bits of the resource number parameter of the reference signal.

[0132] Specifically, in the case where the beam information is represented by the resource number parameter of the SSB signal, the number of bits of the bit map parameter is the same as the number of resource number parameters of the SSB signal, and each bit corresponds to a resource number of the SSB signal; in the case where the beam information is represented by the resource number parameter of the CSI-RS signal, the number of bits of the bit map parameter is the same as the number of resource number parameters of the CSI-RS signal, and each bit corresponds to a resource number of the CSI-RS signal; in the case where the beam information is represented by the resource number parameter of the SRS signal, the number of bits of the bit map parameter is the same as the number of resource number parameters of the SRS signal, and each bit corresponds to a resource number of the SRS signal.

[0133] In one embodiment, the beam information includes uplink beam information and / or downlink beam information; the downlink beam information is represented by the resource number parameter of the SSB signal or the resource number parameter of the CSI-RS signal; and the uplink beam information is represented by the resource number parameter of the SSB signal, the resource number parameter of the CSI-RS signal, or the resource number parameter of the SRS signal.

[0134] Specifically, the beam information can include only uplink beam information, or only downlink beam information, or both uplink beam information and downlink beam information.

[0135] In summary, based on the above limitations of the resource notification message, the resource notification message in this application can use the following formats to provide the terminal device with downlink beam information that does not need to be monitored and uplink beam information that does not need to be monitored. The downlink beam information that does not need to be monitored and the uplink beam information that does not need to be monitored can use any of formats one to three, and the downlink beam information and the uplink beam information can use different formats respectively.

[0136] Format one: the resource notification message lists the beam numbers that do not need to be monitored.

[0137] Specifically, the downlink beam number uses SSB resource number or CSI-RS resource number, and the uplink beam number can use any one of SSB resource number, CSI-RS resource number and SRS resource number.

[0138] Format two: the resource notification message lists the beam numbers that need to be monitored.

[0139] Specifically, the terminal device excludes the beam numbers that need to be monitored from all the beam numbers sent by the cell, and the remaining beam numbers are the beam numbers that do not need to be monitored. The downlink beam number uses SSB resource number or CSI-RS resource number, and the uplink beam number uses any one of SSB resource number, CSI-RS resource number and SRS resource number.

[0140] Format three: the resource notification message informs the terminal device which beams need to be monitored and which beams do not need to be monitored through a bit map parameter. The number of bits of the bit map parameter is consistent with the number of beam numbers, that is, consistent with the number of resource numbers.

[0141] In the case where the beam number is marked using SSB resource number, if the number of SSB-Index is 8, the number of bits of the bit map parameter in the resource notification message is also 8. Each bit corresponds to an SSB-Index (for example, the leftmost bit corresponds to SSB-Index 0, and the subsequent bits correspond to SSB-Index 1, SSB-Index 2, etc. from left to right), and the value of the bit indicates whether the corresponding beam needs to be monitored (for example, a bit value of 1 indicates that the beam needs to be monitored, and a bit value of 0 indicates that the beam does not need to be monitored. In other embodiments, other values can also be used, which are not limited here).

[0142] In the case where the beam number is marked using CSI-RS resource number, the number of bits of the bit map parameter in the resource notification message is consistent with the number of ResourceIds contained in NZP-CSI-RS-ResourceSet. Each bit corresponds to an NZP-CSI-RS-ResourceId, and the value of the bit indicates whether the corresponding beam needs to be monitored.

[0143] In the case where the beam number is marked using the SRS resource number, the number of bits of the bit map parameter in the resource notification message is consistent with the number of SRS-ResourceIds contained in the SRS-ResourceSet, each bit corresponds to an SRS-ResourceId, and whether the corresponding beam needs to be monitored is indicated by the bit value.

[0144] The downlink beam information that does not need to be monitored corresponds to the bit map parameter of the resource number parameter of the SSB signal or the resource number parameter of the CSI-RS signal. The uplink beam information that does not need to be monitored corresponds to the bit map parameter of the resource number parameter of the SSB signal, the resource number parameter of the CSI-RS signal, or the resource number parameter of the SRS signal.

[0145] In one embodiment, the beam information includes uplink beam information and downlink beam information; in the case where the uplink beam information and the downlink beam information are jointly managed, the uplink beam information and the downlink beam information are the same, and the uplink beam information and the downlink beam information are represented by the resource number parameter of the SSB signal or the resource number parameter of the CSI-RS signal; in the case where the uplink beam information and the downlink beam information are managed respectively, the uplink beam information and the downlink beam information are different, and the downlink beam information is represented by the resource number parameter of the SSB signal or the resource number parameter of the CSI-RS signal; and the uplink beam information is represented by the resource number parameter of the SRS signal.

[0146] Specifically, in the case where the cell jointly manages the uplink and the downlink, the uplink beam number and the downlink beam number are consistent, and the beam number uses the SSB resource number or the CSI-RS resource number. In the case where the cell distinguishes the uplink and the downlink and manages them respectively, the uplink beam number and the downlink beam number are different, the downlink beam number uses the SSB resource number or the CSI-RS resource number, and the uplink beam number uses the SRS resource number.

[0147] In one embodiment, the resource notification message includes: a newly added user-specific signaling parameter; or a newly added cell-common signaling parameter; or a newly added parameter of an existing user-specific signaling; or a newly added parameter of an existing cell-common signaling.

[0148] The user-specific signaling refers to a signaling that is valid only for one user. The cell-common signaling refers to a signaling that is valid for multiple users in a cell.

[0149] The newly added user-specific signaling refers to a newly defined user-specific signaling in addition to the user-specific signaling defined in the 5G system.

[0150] In one of the embodiments, the newly added user-specific signaling includes: newly added user-specific RRC (Radio Resource Control, RRC) layer signaling or newly added user-specific MAC (Medium Access Control, MAC) layer signaling or newly added user-specific PHY (Physical, PHY) layer signaling. The newly added user-specific signaling is new signaling, not existing signaling. The user-specific signaling is effective for only one user. The newly added user-specific signaling indicates the beam information that does not need to be monitored through the parameters in the newly added user-specific signaling.

[0151] The newly added cell-common signaling refers to newly defined cell-common signaling in addition to the cell-common signaling already defined in the 5G system. In one of the embodiments, the newly added cell-common signaling includes: newly added cell-common RRC layer signaling or newly added cell-common MAC layer signaling or newly added cell-common PHY layer signaling. The newly added cell-common signaling is new signaling, not existing signaling. The cell-common signaling is effective for multiple users in a cell. The newly added cell-common signaling indicates the beam information that does not need to be monitored through the parameters in the newly added cell-common signaling.

[0152] In one of the embodiments, the newly added parameter of the existing user-specific signaling includes: at least one of the already defined user-specific RRC layer signaling, the already defined user-specific MAC layer signaling, and the already defined user-specific PHY layer signaling.

[0153] The existing user-specific signaling refers to the user-specific signaling defined by the 5G system. The user-specific signaling defined by the 5G system includes at least one of the user-specific RRC layer signaling defined by the 5G system, the user-specific MAC layer signaling defined by the 5G system, and the user-specific PHY layer signaling defined by the 5G system. The user-specific RRC layer signaling defined by the 5G system includes but is not limited to RRCReconfiguration signaling and UEAssistanceInformation signaling. The user-specific MAC layer signaling defined by the 5G system includes but is not limited to TCI State Indication for UE-specific PDCCH MAC CE signaling and TCI States Activation / Deactivation for UE-specific PDSCH MAC CE signaling. The user-specific PHY layer signaling defined by the 5G system includes but is not limited to PDCCH DCI format 1_0 with CRC scrambled by C-RNTI signaling, and C-RNTI is an identifier of a user. The existing user-specific signaling indicates the beam information that does not need to be monitored by adding a new parameter.

[0154] In one of the embodiments, the new parameter of the existing cell-common signaling includes at least one of the defined cell-common RRC layer signaling and the cell-common PHY layer signaling defined by the 5G system.

[0155] The existing cell-common signaling refers to the cell-common signaling defined by the 5G system. The cell-common signaling defined by the 5G system includes at least one of the cell-common RRC layer signaling defined by the 5G system and the cell-common PHY layer signaling defined by the 5G system. The cell-common RRC layer signaling defined by the 5G system includes but is not limited to SIB signaling. The cell-common PHY layer signaling defined by the 5G system includes but is not limited to PDCCH DCI format 1_0 with CRC scrambled by P-RNTI or SI-RNTI signaling, and P-RNTI and SI-RNTI are identifiers commonly used by multiple users in a cell. The existing cell-common signaling indicates the beam information that does not need to be monitored by adding a new parameter.

[0156] In the embodiments, the new parameter of the user-specific signaling, the new parameter of the cell-common signaling, the new parameter of the existing user-specific signaling, and the new parameter of the existing cell-common signaling can be a resource number parameter or a bit map parameter of a reference signal, and these parameters are located in the corresponding signaling.

[0157] In one of the embodiments, in the case that the resource notification message includes parameters of newly added cell common signaling, the parameters of the newly added cell common signaling are generated based on different beams; in the case that the resource notification message includes newly added parameters of existing cell common signaling, the newly added parameters of the existing cell common signaling are generated based on different beams; in the case that the resource notification message includes parameters of newly added user-specific signaling, the parameters of the newly added user-specific signaling are generated according to the camping beam of the terminal device; in the case that the resource notification message includes newly added parameters of existing user-specific signaling, the newly added parameters of the existing user-specific signaling are generated according to the camping beam of the terminal device.

[0158] For the convenience of understanding, two examples are given for illustration. In the case that the newly added parameters of the resource notification message are SIB messages, the resource notification message needs to be configured for different beams, i.e., the newly added parameters of the SIB messages of different beams are different; in the case that the newly added parameters of the resource notification message are RRC reconfiguration messages, different RRC reconfiguration messages are generated according to the camping beam of the terminal device.

[0159] In one of the embodiments, before the resource notification message is sent to the terminal device, the following steps are included: determining beams that satisfy the condition of spatial division multiplexing with each other, and generating the resource notification message based on the beam information of the beams that satisfy the condition of spatial division multiplexing with each other.

[0160] In one of the embodiments, the beams that satisfy the condition of spatial division multiplexing with each other include a first beam and a second beam; the first beam and the second beam satisfy at least one of the following conditions: the distance between the area pointed to by the first beam and the area pointed to by the second beam is greater than a first threshold; the absolute value of the difference between the antenna angle of the first beam and the antenna angle of the second beam is greater than a second threshold; the absolute value of the difference between the longitude of the area pointed to by the first beam and the longitude of the area pointed to by the second beam is greater than a third threshold; the absolute value of the difference between the latitude of the area pointed to by the first beam and the latitude of the area pointed to by the second beam is greater than a fourth threshold; the absolute value of the difference between the transmission delay of the first beam and the transmission delay of the second beam is greater than a fifth threshold; the absolute value of the difference between the frequency offset of the first beam and the frequency offset of the second beam is greater than a sixth threshold.

[0161] The network device can determine which beams satisfy the condition of spatial division multiplexing through some criteria. The condition of spatial division multiplexing can be combined with the above, but those skilled in the art can understand that the above is only an example. In other embodiments, those skilled in the art can also add other conditions of spatial division multiplexing, which are not specifically limited here.

[0162] In this embodiment, in the case that the cell supports N (N>1) beams, for each beam, find other beams that satisfy the spatial division multiplexing condition with the beam, for example, for beam i, the set of beams that satisfy the spatial division multiplexing condition with beam i is called spatialSegregationBeamSetForBeami. Assuming that the terminal device currently resides in beam i, the network device informs the terminal device of the beam set indicated by spatialSegregationBeamSetForBeami through a resource notification message, and the terminal device considers that the resources occupied by the beams indicated by spatialSegregationBeamSetForBeami are not needed to be monitored, and the resources of the beams that are not needed to be monitored are available.

[0163] In one of the embodiments, the method further includes receiving the acknowledgement reply corresponding to the resource notification message fed back by the terminal device.

[0164] Specifically, in combination with Figure 3 and Figure 4 shown, Figure 3 is a timing diagram of the resource notification method with feedback in one embodiment, Figure 4 is a timing diagram of the resource notification method without feedback in one embodiment.

[0165] In this embodiment, after the network device sends the resource notification message, it waits for the acknowledgement reply of the successful reception of the resource notification message by the terminal device. The "acknowledgement reply" here can be a newly added RRC, MAC or physical layer signaling message (PHY signaling includes but is not limited to PDCCH order), or a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the physical layer.

[0166] In the resource notification message interaction method as shown in Figure 3 , the network device considers that the terminal device has successfully received the resource notification message only after receiving the acknowledgement reply fed back by the terminal device; in the resource notification message interaction method as shown in Figure 4 , the network device considers that the terminal device has successfully received the resource notification message by default after sending the resource notification message.

[0167] In one of the embodiments, the method further includes performing data transmission with the terminal device through the resources occupied by the beams that are not needed to be monitored.

[0168] Among them, in this embodiment, for the beams that the terminal device does not need to monitor, the resources occupied by these beams (such as reference signal resources or common channel resources) are available, and the network device can use these available resources to schedule uplink or downlink data for the terminal device.

[0169] In one of the embodiments, data transmission with a terminal device is performed through resources associated with a beam that does not need to be monitored, including: in the downlink direction, sending a PDCCH signal or a PDSCH signal through at least one of the resources of Type0 PDCCH, Type0A PDCCH, Type1 PDCCH, Type2 PDCCH and SSB signal of the beam that does not need to be monitored; or sending a PDCCH signal or a PDSCH signal through at least one of the resources of Type0 PDCCH, Type 0A PDCCH, Type1 PDCCH, Type2 PDCCH, SSB signal and CSI-RS signal of the beam that does not need to be monitored; in the uplink direction, receiving a PUCCH signal or a PUSCH signal through the resources of PRACH of the beam that does not need to be monitored; or receiving a PUCCH signal or a PUSCH signal through at least one of the resources of PRACH and SRS signal of the beam that does not need to be monitored.

[0170] Specifically, after the terminal device successfully receives the resource notification message, for the beam spatialSegregationBeamSetForBeami that the terminal device does not need to monitor, the network device performs the following operations:

[0171] In the downlink direction, the network device considers the SSB signals, Type 0 PDCCH resources, Type 0 APDCCH resources, Type 1 PDCCH resources, and Type 2 PDCCH resources of these beams to be available, and allows scheduling PDCCH signals or PDSCH signals for terminal devices on these resources, that is, sending PDCCH signals or PDSCH signals to terminal devices. If these beams are also configured with associated CSI-RS signals, the network device also considers the CSI-RS resources occupied by these beams to be available. Similarly, it allows scheduling PDCCH signals or PDSCH signals for terminal devices on these resources, that is, sending PDCCH signals or PDSCH signals to terminal devices.

[0172] In the uplink direction, the network device considers that the resources of the PRACH signals of these beams are available, and allows to schedule PUCCH signals or PUSCH signals for the terminal device at these resources, i.e., receives the PUCCH signals or PUSCH signals sent by the terminal device. If the SRS signals are also configured for these beams, the network device also considers that the resources of the SRS signals of these beams are available, and for the same reason, allows to schedule PUCCH signals or PUSCH signals for the terminal device at the resources of the SRS signals, i.e., receives the PUCCH signals or PUSCH signals sent by the terminal device.

[0173] In one of the embodiments, the method further includes: in the case where the terminal device switches from an old beam to a new beam, modifying the beam information of the beams that do not need to be monitored by the terminal device based on the resource notification message received from the new beam.

[0174] Specifically, when the terminal device switches from an old beam to a new beam, the beam information of the beams that do not need to be monitored received by the terminal device on the old beam does not take effect on the new beam. The terminal device acquires the resource notification message received on the new beam, and re-determines the beam information of the beams that do not need to be monitored based on the resource notification message received on the new beam. If the terminal device does not receive the resource notification message on the new beam, both the terminal device and the network device consider that the terminal device needs to monitor all the beams of the cell.

[0175] In one of the embodiments, as shown in Figure 5 , a resource notification method is provided, which is applied to the terminal device in Figure 1 for example, and includes the following steps.

[0176] S502: receiving a resource notification message sent by a network device.

[0177] The resource notification message is sent by the network device to the terminal device. In one of the embodiments, the beam information is represented by the resource number parameter of the reference signal, and the reference signal includes SSB signals, CSI-RS signals or SRS signals. For specific limitations of the resource notification message, please refer to the embodiments in the foregoing description, which will not be repeated here.

[0178] S504: determining the beam information of the beams that do not need to be monitored based on the resource notification message.

[0179] The resource notification message can directly or indirectly represent which beams do not need to be monitored, for example, the resource notification message can only include the beam information of the beams that do not need to be monitored, or only include the beam information of the beams that need to be monitored, or include both the beam information of the beams that need to be monitored and the beam information of the beams that do not need to be monitored.

[0180] In one of the embodiments, determining the beam information of the beams not needed to be monitored based on the resource notification message comprises: in the case that the resource notification message comprises the beam information of the beams not needed to be monitored, parsing the resource notification message to obtain the beam information of the beams not needed to be monitored; in the case that the resource notification message comprises the beam information of the beams needed to be monitored, parsing the resource notification message to obtain the beam information of the beams needed to be monitored, and obtaining the beam information of the beams not needed to be monitored based on the beam information of the beams needed to be monitored.

[0181] Specifically, in the case that the scene conventionally indicates that the resource notification message sends the beam information of the beams not needed to be monitored, the beam information of the beams not needed to be monitored can be obtained by directly parsing the resource notification message. In the case that the scene conventionally indicates that the resource notification message sends the beam information of the beams needed to be monitored, the beam information of the beams not needed to be monitored can be obtained by parsing the resource notification message to obtain the beam information of the beams needed to be monitored, and then combining the beam information of all the beams of the cell.

[0182] In actual application, in the case that the resource notification message uses the resource number parameter of the reference signal, the resource number parameter can be the beam information of the beams needed to be monitored, or the resource number parameter can be the beam information of the beams not needed to be monitored. In the case that the resource notification message uses the bit map parameter, the beam information of the beams not needed to be monitored is determined by the value of the bit.

[0183] S506: performing data transmission of uplink data or downlink data based on the resource occupied by the beams not needed to be monitored.

[0184] In the embodiment, the resource occupied by the beams not needed to be monitored does not need to be monitored and measured, that is, the terminal device considers that the resource occupied by the beams not needed to be monitored is available, and thus the terminal device can perform data transmission of uplink data or downlink data based on the resource occupied by the beams not needed to be monitored. Similarly, the network device also considers that the terminal device can perform data transmission of uplink data or downlink data based on the resource occupied by the beams not needed to be monitored.

[0185] In one of the embodiments, the data transmission of uplink data or downlink data based on the resource associated with the beam that does not need to be monitored includes: in the downlink direction, receiving the PDCCH signal or the PDSCH signal through at least one of the SSB signal, the resource of Type0 PDCCH, the resource of Type0A PDCCH, the resource of Type1 PDCCH, the resource of Type2 PDCCH of the beam that does not need to be monitored; or receiving the PDCCH signal or the PDSCH signal through at least one of the SSB signal, the resource of Type0 PDCCH, the resource of Type0A PDCCH, the resource of Type1 PDCCH, the resource of Type2 PDCCH and the resource of CSI-RS signal of the beam that does not need to be monitored; in the uplink direction, transmitting the PUCCH signal or the PUSCH signal through the resource of PRACH of the beam that does not need to be monitored; or transmitting the PUCCH signal or the PUSCH signal through at least one of the resource of PRACH and the resource of SRS signal of the beam that does not need to be monitored.

[0186] Specifically, in the downlink direction, the terminal device considers that the SSB signal, the resource of Type0 PDCCH, the resource of Type0A PDCCH, the resource of Type1 PDCCH, the resource of Type2 PDCCH of the beam do not need to be monitored, and the network device transmits the PDCCH signal or the PDSCH signal to the terminal device on these resources, and the terminal device normally receives the PDCCH signal or the PDSCH signal transmitted by the network device. If the beam is also configured with the CSI-RS signal, the terminal device considers that the CSI-RS resource of the beam does not need to be monitored, and for the same reason, the network device transmits the PDCCH signal or the PDSCH signal to the terminal device on the resource of the CSI-RS signal, and the terminal device normally receives the PDCCH signal or the PDSCH signal.

[0187] In the uplink direction, the terminal device considers that the resource of PRACH of the beam is available, and does not select these resources to transmit the preamble, and the network device schedules the PUCCH signal or the PUSCH signal for the terminal device on these available resources, and the terminal device normally transmits the PUCCH signal or the PUSCH signal to the network device. If the beam is also configured with the SRS signal, the terminal device considers that the SRS resource of the beam is available, and does not need to transmit the SRS signal of the beam, and for the same reason, the network device schedules the PUCCH signal or the PUSCH signal for the terminal device at these available resources, and the terminal device normally transmits the PUCCH signal or the PUSCH signal to the network device.

[0188] The resource notification method receives the resource notification message sent by the network device in advance, so that the beam information of the beams that do not need to be monitored can be determined, and then the data transmission of uplink data or downlink data is performed based on the resources occupied by the beams that do not need to be monitored, thereby increasing the wireless resources available to users on each beam, improving the utilization rate of cell wireless resources and throughput.

[0189] In one of the embodiments, the terminal device does not need to send the SRS signal on the resource corresponding to the SRS signal of the beam that does not need to be monitored, does not need to listen to the common channel and system message corresponding to the beam that does not need to be monitored, and does not need to measure the signal information of the SSB signal and the CSI-RS signal corresponding to the beam that does not need to be monitored.

[0190] The SRS signal is a signal sent in the uplink direction. Since the terminal device does not need to monitor some beams, the resources of the SRS signals of the beams are available, that is, the terminal device does not need to send the SRS signal.

[0191] In one of the embodiments, the method further includes: in the case of sending the CSI in the uplink direction, determining the CSI-RS signal quality value of the beam that does not need to be monitored as the minimum value of the CQI (Channel Quality Indicator, CQI) specified in the 5G system.

[0192] Specifically, when the terminal device reports the CSI, for the beams that do not need to be monitored by the terminal device indicated by the resource notification message, the CSI-RS signal quality value of the beams is the minimum value of the CQI specified in the 5G system by default.

[0193] The SSB signal and the CSI-RS signal are signals sent in the downlink direction. The network device sends the SSB signal and the CSI-RS signal corresponding to all beams. However, since the terminal device does not need to monitor some beams, the terminal device does not need to listen to the common channel and system message of the beams that do not need to be monitored, and does not need to measure the signal information of the SSB signal and the CSI-RS signal corresponding to the beams that do not need to be monitored. For example, in the case where the beam number is marked using the SSB resource number, when the terminal device performs the layer three measurement based on the SSB signal for the beams that do not need to be monitored by the terminal device indicated by the resource notification message, the terminal device does not need to measure the SSB signal strength and quality of the beams that do not need to be monitored by the terminal device. In the case where the beam number is marked using the CSI-RS resource number, when the terminal device performs the layer three measurement based on the CSI-RS signal for the beams that do not need to be monitored by the terminal device indicated by the resource notification message, the terminal device does not need to measure the CSI-RS signal strength and quality of the beams that do not need to be monitored by the terminal device.

[0194] In the above embodiments, the terminal can not measure the weak reference signal and monitor the weak common channel, thereby saving power of the terminal.

[0195] In one of the embodiments, after receiving the resource notification message sent by the network device, the method further includes: sending an acknowledgement reply corresponding to the resource notification message to the network device.

[0196] In one of the embodiments, the method further includes: Figure 3 and Figure 4 As shown in Figure 3 The resource notification method with feedback is shown, that is, after the network device sends a resource notification message to the terminal device, if the terminal device successfully receives the notification message, the network device feeds back an acknowledgement reply. Figure 4 The resource notification method without feedback is shown, that is, after the network device sends a resource notification message to the terminal device, the terminal device can successfully receive the notification message by default, and does not need to feed back an acknowledgement reply.

[0197] In one of the embodiments, the method further includes: in the case of switching from an old beam to a new beam, modifying the beam information of the beams that do not need to be monitored corresponding to the terminal device based on the resource notification message received from the new beam.

[0198] In one of the embodiments, the method further includes: in the case of not receiving the resource notification message on the new beam, monitoring all beams in the cell coverage.

[0199] In one of the embodiments, the method further includes: in the case of switching from an old beam to a new beam, modifying the beam information of the beams that do not need to be monitored corresponding to the terminal device based on the resource notification message received from the new beam.

[0200] For the convenience of understanding, a specific example is given to illustrate the present application, assuming that the terminal device accesses a satellite cell having 8 same-frequency beams with different scanning directions, and the beam numbers are SSB-index 0~7, such as Figure 6 SSB-index 0, SSB-index 1, SSB-index 2, SSB-index 3, SSB-index 4, SSB-index 5, SSB-index 6 and SSB-index 7 in Figure 6 Each beam provides uplink service and downlink service at the same time, that is, the uplink beam and the downlink beam are completely overlapped. The 8 beams scan the area on the ground as shown in Figure 6 .

[0201] In Figure 6 the same time, the satellite base station can emit 2 beams, then the base station needs to scan the beam SSB-index 0~7 by time division manner, assuming that the interval between the beams exceeds the diameter of a beam, it is considered that the two beams meet the space division multiplexing condition, then for beam 0, beams 2, 3, 4, 5 meet the space division multiplexing condition with beam 0; for beam 3, beams 0, 1, 6, 7 meet the space division multiplexing condition with beam 3.

[0202] For the user of beam 0, the resource notification message generated by the network device contains the following parameters according to format one to format three

[0203] Format one: the resource notification message contains SSB-index 2, SSB-index 3, SSB-index 4, SSB-index 5, and the UE directly obtains the beam numbers SSB-index 2, SSB-index 3, SSB-index 4, SSB-index 5 that do not need to be monitored.

[0204] Format two: the resource notification message contains SSB-index 0, SSB-index 1, SSB-index 6, SSB-index 7, SSB-index 0, SSB-index 1, SSB-index 6, SSB-index 7 are the beam numbers that the terminal device of beam 0 needs to monitor, since all the beam numbers sent by the cell are SSB-index 0~7, the terminal device indirectly deduces that the beam numbers SSB-index 2, SSB-index 3, SSB-index 4, SSB-index 5 do not need to be monitored.

[0205] Format three: the resource notification message contains a bit map parameter with a value of 11000011, the leftmost bit corresponds to SSB-Index 0, from left to right, the subsequent bits correspond to SSB-Index 1, SSB-Index 2, etc., bit value 1 indicates that the beam needs to be monitored, and bit value 0 indicates that the beam does not need to be monitored. The terminal device indirectly deduces that the beam numbers SSB-index 2, SSB-index 3, SSB-index 4, SSB-index 5 do not need to be monitored through the bit map parameter.

[0206] Similarly, for the terminal device of beam 3, the beam information of the beams that do not need to be monitored generates the resource notification message according to format one to format three, containing the following parameters:

[0207] Format one: the resource notification message contains SSB-index 0, SSB-index 1, SSB-index 6, SSB-index 7, the terminal device directly obtains the beam numbers SSB-index 0, SSB-index 1, SSB-index 6, SSB-index 7 that do not need to be monitored.

[0208] Format two: the resource notification message contains SSB-index 2, SSB-index 3, SSB-index 4, SSB-index 5, the terminal device indirectly obtains the beam numbers SSB-index 0, SSB-index 1, SSB-index 6, SSB-index 7 that do not need to be monitored.

[0209] Format three: the resource notification message contains a bit map parameter with a value of 00111100, the terminal device indirectly obtains the beam numbers SSB-index 0, SSB-index 1, SSB-index 6, SSB-index 7 that do not need to be monitored.

[0210] After the network device sends the resource notification message to the terminal device, the scheduling strategy of the network device is as follows:

[0211] Assume that the cell works in the FDD frequency band above 3GHz, SCS=30KHz, 1 subframe (i.e. 1ms) contains 2 slots, the cell bandwidth is 20MHz (51RB), Figure 7 An example of the resource positions occupied by the SSB, Type0 PDCCH, Type0A PDCCH, Type2 PDCCH, SIB, CSI-RS of the cell downlink is given, wherein, in order to facilitate and simplify the display, only slot numbers 0-39 (32-29 are not shown) and corresponding subframe numbers 0-19 (16-19 are not shown) are given, other slot numbers and corresponding subframe numbers can be obtained periodically based on slot numbers 0-39 (32-29 are not shown) and corresponding subframe numbers 0-19 (16-19 are not shown), Figure 8 An example of the resource positions occupied by the PRACH, SRS of the cell uplink is given.

[0212] For any terminal device in wave position 0, since the terminal device does not need to monitor the Type0 PDCCH, Type0A PDCCH, Type2 PDCCH, SSB signal and CSI-RS signal associated with beams SSB-index 2, SSB-index 3, SSB-index 4 and SSB-index 5, nor does it need to send the PRACH and SRS signals associated with beams SSB-index 2, SSB-index 3, SSB-index 4 and SSB-index 5, the resource locations occupied by Type0 PDCCH, Type0A PDCCH, Type2 PDCCH, SSB, SIB and CSI-RS in the downlink of wave position 0 are as follows: Figure 8 As shown, for the sake of simplicity, only time slot numbers 0-39 (32-29 are not shown) and corresponding subframe numbers 0-19 (16-19 are not shown) are given. Other time slot numbers and corresponding subframe numbers can be obtained periodically based on time slot numbers 0-39 (32-29 are not shown) and corresponding subframe numbers 0-19 (16-19 are not shown). The resource locations occupied by PRACH and SRS in the uplink of wave position 0 are shown as follows. Figure 9 shown.

[0213] contrast Figure 7 and Figure 9 It can be seen that for terminal devices at wave position 0, the number of beams that need to be monitored is reduced from 8 to 4, so the resources occupied by downlink reference signals, common channels and system messages are reduced by half, and the PDCCH and PDSCH resources that can be scheduled by network equipment at wave position 0 are increased.

[0214] contrast Figure 8 and Figure 10 It can be seen that for terminal devices at wave position 0, the number of beams that need to be monitored is reduced from 8 to 4, so the resources occupied by the uplink reference signal and common channel are reduced by half, and the PUCCH and PUSCH resources that can be scheduled by network equipment at wave position 0 are increased.

[0215] In the above embodiment, when a cell supports multiple beams, the resource notification method of this application can be introduced to increase the wireless resources available to users on each beam, thereby improving the wireless resource utilization and throughput of the cell. Furthermore, it can prevent terminal devices from measuring weak reference signals or monitoring weak common channels, thus achieving terminal energy conservation.
