[0016] The headings of the following sections are used to facilitate understanding of the disclosed subject matter and do not limit the scope of the claimed subject matter in any way. Therefore, one or more features of one section may be combined with one or more features of another section. In addition, for clarity of explanation, 6G or integrated sensing and communication (ISAC) terminology is used. Nevertheless, the technology disclosed in this application is not limited to 6G or ISAC technology, and can be used in wireless systems implementing other protocols.

[0017] ISAC is expected to add considerable value to wireless communication systems. Widely deployed communication infrastructure can be enhanced to provide radar services such as traffic control and monitoring, drone detection, and railway obstacle detection. ISAC can also be implemented in various mobile communication devices in autonomous driving, smart home, and healthcare scenarios.

[0018] Communication systems and radar systems utilize electromagnetic waves in two different ways. The idea of ​​dual-function design can be traced back to the 1960s. In recent years, it has attracted increasing research attention, and there are many driving factors, including (1) the spectrum has been well used for two independent systems, and joint spectrum utilization is expected to improve efficiency and flexibility; (2) hardware design has a technical trend of multi-antenna and digital baseband, and hardware sharing saves costs; (3) information fusion and mutual reinforcement of the two functions bring performance gains, especially for autonomous vehicles. Existing radars usually transmit a set of periodic broadband perception signals. However, in order to coexist with communication functions, resource allocation should be more flexible.

[0019] In radar systems, a set of periodic broadband sensing signals are usually transmitted. However, in ISAC or other communication systems, time-frequency resources need to be shared between sensing and communication. The periodic broadband resource allocation of sensing signals will consume a lot of resources, which is not friendly to communication services. Therefore, ISAC needs a more flexible way to allocate sensing signals to reduce overhead.

[0020] The patent application proposes methods and schemes involving multiple resource allocation patterns that can be flexibly used in ISAC and other communication systems. The proposed methods and schemes improve system performance by at least reducing the overhead involved in the communication process.

[0021] The details of the proposed method are discussed in the following examples.

[0022] Example 1

[0023] In particular, this section discloses examples of how to configure and send awareness resource patterns within a wireless communication system.

[0024] The perception resource pattern can be configured through high-level nodes.

[0025] In one example, the core network (CN) may directly send configuration information of multiple sensing resource sets to the BS. Figure 1 As shown, the CN sends multiple sensing resource sets to B1 (102) and B2 (104).

[0026] The configuration information of multiple aware resource sets may include at least one of the following: resource set ID, periodicity and resource set slot offset, resource repetition factor, resource time gap, silent option, SFN0 offset, resource list, comb size, resource bandwidth, starting physical resource block (PRB) or number of symbols in a slot.

[0027] according to Figure 1 , BS1 receives the configuration information and allocates the perception signal according to the configuration information.

[0028] BS1 sends out the sensing signal (106). The sensing signal reaches the sensing target, and the corresponding echo signal propagates to the receiving antenna of BS2 (108).

[0029] Since BS2 has received multiple sensing resource sets from CN, BS2 receives the echo signal according to the sensing resource sets.

[0030] Example 2

[0031] In particular, this section discloses examples relating to how to configure and send awareness resource patterns within a wireless communication network.

[0032] The perception resource pattern can be configured through high-level nodes.

[0033] In one example, the CN may directly send configuration information of multiple sensing resource sets to the BS. Figure 2 As shown, CN sends multiple sensing resource sets and multiple frequency layers to BS1 (202).

[0034] The configuration information of multiple resource sets may include at least one of the following: resource set ID, periodicity and resource set time slot offset, resource repetition factor, resource time gap, silent option, SFN0 offset, resource list, comb size, resource bandwidth, starting PRB or number of symbols in the time slot.

[0035] The configuration information of multiple frequency layers may contain the same parameters. For example, the parameters may include subcarrier spacing, cyclic prefix, and point A. In other words, if two frequency resources have the same subcarrier spacing, cyclic prefix, and / or point A, it can be determined that they belong to the same layer.

[0036] like Figure 2 As shown, BS1 receives the configuration information and allocates the perception signal according to the configuration information.

[0037] BS1 sends the sensing resource allocation information to UE or BS2 (204). Then, BS1 sends the sensing signal (206).

[0038] The sensing signal may reach the sensing target, and the corresponding echo signal propagates to the receiving antenna of the UE or BS2 (208).

[0039] Since the UE or BS2 has received the sensing resource allocation information from BS1, the UE or BS2 can receive the echo signal according to the resource configuration.

[0040] Example 3

[0041] This embodiment particularly discloses multiple examples related to how to configure and send sensing resource patterns within a wireless communication network.

[0042] The perception resource pattern can be configured through high-level nodes.

[0043] In one example, the CN may directly send configuration information of multiple sensing resource sets to the BS. Figure 3 As shown, the CN sends a plurality of sensing resource sets and a plurality of frequency layers to the BS (302).

[0044] This embodiment shows how to configure and send a sensing resource pattern. CN directly sends configuration information of multiple sensing resource sets and multiple frequency layers to BS1.

[0045] The configuration information of multiple resource sets may include at least one of the following: resource set ID, periodicity and resource set time slot offset, resource repetition factor, resource time gap, silent option, SFN0 offset, resource list, comb size, resource bandwidth, starting PRB or number of symbols in the time slot.

[0046] The configuration information of multiple frequency layers may contain the same parameters. For example, the parameters may include subcarrier spacing, cyclic prefix, and point A. In other words, if two frequency resources have the same subcarrier spacing, cyclic prefix, and / or point A, it can be determined that they belong to the same layer.

[0047] like Figure 3As shown, the BS receives the configuration information and allocates the perception signal according to the configuration information.

[0048] The BS sends out a sensing signal (304).

[0049] The sensing signal may reach the sensing target, and the corresponding echo signal propagates back to the BS (306).

[0050] Since the BS has received the sensing resource allocation information from the CN, the BS can receive the echo signal according to the resource configuration.

[0051] Example 4

[0052] This embodiment particularly discloses an embodiment involving configuration of multiple sensing resource sets.

[0053] For example, Figure 4 As shown, two different time resource sets can be configured.

[0054] The resource locations of two resource sets are indicated by the following: 1) resource set ID, 2) periodicity and resource set slot offset, 3) resource repetition factor, 4) resource time gap, 5) parameter indicating muting option, 6) SFN0 offset, 7) resource list, 8) comb size, 9) resource bandwidth, 10) starting physical resource block (PRB) or 11) number of symbols in a slot in multiple resource set configurations.

[0055] The resource list includes resources of at least one resource set, and the resources are also represented by: 1) resource ID, 2) sequence ID, 3) comb size and resource unit offset, 4) resource time slot offset, 5) resource symbol offset and 6) quasi co-location (QCL) information.

[0056] The configuration is intended to enable the sensing resource set to have different time and frequency patterns to obtain sensing results of different distances and Doppler resolutions. Some algorithms use sensing results of different resolutions to obtain high-resolution public sensing results. The public sensing results can be sent to at least one core network, a server close to the second or third wireless device.

[0057] like Figure 4 As shown, resource A has a bandwidth of 66 resource blocks (RBs) and a periodicity or repetition factor of 4 time slots. In other words, set A can be configured to use the first of every four time slots to send information. In each first time slot of the selected first time slot, set A can also be configured to use the third symbol of the 14 symbols to send relevant information.

[0058] Resource B has a bandwidth of 1 subcarrier and a periodicity or repetition factor of 7 symbols. In other words, set B can be configured to all time slots in the 128 time slots for sending information. In each of the 128 time slots, set B can also be configured to use the 7th symbol and the 14th symbol of the 14 symbols to send relevant information.

[0059] The example in this embodiment shows that the proposed multi-sensing resource set scheme can achieve flexibility in resource allocation. In particular, a resource set (sensing resource set A) having a relatively wide frequency band (e.g., 66 RBs) in frequency and less frequent occupancy in time (one time slot in four time slots and one symbol in 14 symbols) can be generated together with a resource set (sensing resource set B) having a relatively narrow frequency band (e.g., one subcarrier) in frequency and more frequent occupancy in time (two symbols in each time slot and 14 symbols).

[0060] A network node receiving a configuration of two different sensing sets can utilize resource allocation patterns based on different communication scenarios. Since the two sensing sets have different bandwidths and time domain densities, joint processing can be used to provide high-performance sensing results. However, traditional methods to achieve such performance require more resource overhead. Therefore, the proposed method improves efficiency and saves resource allocation of the wireless communication network. Since common sensing results are obtained from multiple sensing resource sets, the sensing result transmission overhead or feedback overhead can also be reduced.

[0061] Example 5

[0062] This embodiment particularly discloses an example of configuration involving multiple resource sets.

[0063] For example, Figure 5 As shown, three different time resource sets can be configured.

[0064] The resource location of a resource set is indicated by the following: 1) resource set ID, 2) periodicity and resource set slot offset, 3) resource repetition factor, 4) resource time gap, 5) parameter indicating muting option, 6) SFN0 offset, 7) resource list, 8) comb size, 9) resource bandwidth, 10) starting physical resource block (PRB) or 11) number of symbols within a slot in multiple resource set configurations.

[0065] The resource list includes resources of at least one resource set, and the resources are also represented by: 1) resource ID, 2) sequence ID, 3) comb size and resource unit offset, 4) resource time slot offset, 5) resource symbol offset and 6) QCL information.

[0066] The configuration is intended to enable the sensing resource set to have different time and frequency patterns to obtain sensing results of different distances and Doppler resolutions. Some algorithms use sensing results of different resolutions to obtain high-resolution public sensing results. The public sensing results can be sent to at least one core network, a server close to the second or third wireless device.

[0067] like Figure 5 As shown, resource A has a bandwidth of 264 resource blocks (RBs) and a periodicity or repetition factor of 4 time slots. In other words, set A can be configured to use the first time slot of every four time slots to send information. In each first time slot of the selected first time slot, set A can also be configured to use the fifth symbol of the 14 symbols to send relevant information.

[0068] Resource B has a bandwidth of 6 RBs and a periodicity or repetition factor of 7 symbols. In other words, set B can be configured for all time slots in the 128 time slots for sending information. In each of the 128 time slots, set B can also be configured to use the 7th symbol and the 14th symbol of the 14 symbols to send relevant information.

[0069] Resource C has a bandwidth of 528 RBs and a periodicity or repetition factor of 8 time slots. In other words, set C can be configured to use the first time slot of every eight time slots in 128 time slots. In each of the 128 time slots, set C can also be configured to use the second symbol of the 14 symbols to send relevant information.

[0070] The examples in this embodiment show that the proposed multi-sensing resource set scheme can achieve flexibility in resource allocation. Sensing resource set A has a relatively wide frequency band (e.g., 264 RBs) in frequency and less frequent occupancy in time (one slot in four time slots and one in 14 symbols). Transmitting resource set B has a relatively narrow frequency band (e.g., 6 RBs) in frequency and more frequent occupancy in time (two symbols in each time slot and 14 symbols). Sensing resource set C occupies a very large frequency band (e.g., 528 RBs) and very little occupancy in time (one in seven time slots and one in 14 symbols).

[0071] A network node receiving a configuration of three different sensing sets can utilize resource allocation patterns based on different communication scenarios. Since the sensing sets have different bandwidths and time domain densities, joint processing can be used to provide high-performance sensing results. However, traditional methods to achieve such performance require more resource overhead. Therefore, the proposed method improves efficiency and saves resource allocation of the wireless communication network. Since common sensing results are obtained from multiple sensing resource sets, the sensing result transmission overhead or feedback overhead can also be reduced.

[0072] Example 6

[0073] This embodiment particularly discloses an example involving configuration of multiple resource sets in different layers.

[0074] Figure 6 An example of three different sets of time resources on two different frequency layers is disclosed.

[0075] The resource location of a resource set is indicated by the following: 1) resource set ID, 2) periodicity and resource set slot offset, 3) resource repetition factor, 4) resource time gap, 5) parameter indicating muting option, 6) SFN0 offset, 7) resource list, 8) comb size, 9) resource bandwidth, 10) starting physical resource block (PRB) or 11) number of symbols within a slot in multiple resource set configurations.

[0076] The resource list includes resources of at least one resource set, and the resources are also represented by: 1) resource ID, 2) sequence ID, 3) comb size and resource unit offset, 4) resource time slot offset, 5) resource symbol offset and 6) QCL information.

[0077] The configuration is intended to enable the sensing resource set to have different time and frequency patterns to obtain sensing results of different distances and Doppler resolutions. Some algorithms use sensing results of different resolutions to obtain high-resolution public sensing results. The public sensing results can be sent to at least one core network, a server close to the second or third wireless device.

[0078] Frequency resources of different layers may have different values ​​for certain parameters (eg, subcarrier spacing, cyclic prefix, or point A).

[0079] For example, in Figure 6 In the example shown, frequency layer 1 has a subcarrier spacing of 30 kHz, a normal cyclic prefix, and a point A of 2600.45 MHz. Frequency layer 2 has a subcarrier spacing of 60 kHz, an extended cyclic prefix, and a point A of 24600.78 MHz.

[0080] according to Figure 6 , frequency layer 1 has two resource sets A and B.

[0081] like Figure 6 As shown, resource A has a bandwidth of 264 resource blocks (RBs) and a periodicity or repetition factor of 4 time slots. In other words, set A can be configured to use the first time slot of every four time slots for sending information. In each first time slot of the selected first time slot, set A can also be configured to use the fifth symbol of the 14 symbols to send relevant information.

[0082] Resource B has a bandwidth of 1 subcarrier and a periodicity or repetition factor of 7 symbols. In other words, set B can be configured to all time slots in the 128 time slots for sending information. In each of the 128 time slots, set B can also be configured to use the 7th symbol and the 14th symbol of the 14 symbols to send relevant information.

[0083] according to Figure 6 , frequency layer 2 has a resource set C.

[0084] Resource C has a bandwidth of 528 RBs and a periodicity or repetition factor of 8 time slots. In other words, set C can be configured to use the first time slot of every eight time slots in 128 time slots. In each of the 128 time slots, set C can also be configured to use the second symbol of the 14 symbols to send relevant information.

[0085] The examples in this embodiment show that the proposed multi-sensing resource set scheme can achieve flexibility in resource allocation. In particular, the sensing resource set A has a wide frequency band (e.g., 264 RBs) in frequency and less frequent occupancy in time (one slot in four slots and one symbol in 14 symbols). The transmission resource set B has a relatively narrow frequency band (e.g., 6 RBs) in frequency and more frequent occupancy in time (two in each slot and 14 symbols). The sensing resource set C occupies a very large frequency band (e.g., 528 RBs) and very little occupancy in time (one slot in seven slots and one symbol in 14 symbols). In addition, the three sensing resource sets have different frequency layers.

[0086] A network node receiving a configuration of three different sensing sets can utilize resource allocation patterns based on different communication scenarios. Since the sensing sets have different bandwidths and time domain densities, joint processing can be used to provide high-performance sensing results. However, traditional methods to achieve such performance require more resource overhead. Therefore, the proposed method improves efficiency and saves resource allocation of the wireless communication network. Since common sensing results are obtained from multiple sensing resource sets, the sensing result transmission overhead or feedback overhead can also be reduced.

[0087] Example 7

[0088] This embodiment particularly discloses an example of how to handle resource conflicts among multiple resource sets.

[0089] Figure 7 A scenario of resource allocation conflict between two resource sets is disclosed.

[0090] according to Figure 7 , two resource sets A and B belong to the same frequency layer.

[0091] Resource A has a bandwidth of 1 subcarrier and a periodicity or repetition factor of 1 time slot. In other words, set A can be configured to use all time slots of 128 time slots to send information. In each time slot, set A can also be configured to use the third symbol of the 14 symbols to send relevant information.

[0092] Resource B has a bandwidth of 792 subcarriers and a periodicity or repetition factor of 4 time slots. In other words, set B can be configured to send information in the first time slot of every four time slots in 128 time slots. In each of the 128 time slots, set B can also be configured to use the third symbol of the 14 symbols to send relevant information.

[0093] like Figure 7 As shown, sets A and B use the third symbol in the selected time slot, which leads to a potential resource allocation conflict.

[0094] There are a number of solutions that can be used to resolve resource allocation conflicts.

[0095] For example, one way to eliminate resource conflicts is to set some silent options. In one example, Figure 7 As shown, resource set A can adopt the option of being silent every four time slots. In other words, set A can avoid transmitting in the first time slot of every four time slots, which avoids potential allocation conflicts with set B in each of the first time slots of the four time slots.

[0096] The second way is to configure the priority options and only allow the resource set with higher priority to use the conflicting resources. For example, sets A and B can be configured with different priorities to use time-frequency resources. When a conflict occurs, the one with higher priority between set A and set B is authorized to use the resource.

[0097] The third way is to resolve conflicts via rules involving resource set indexes and predefined rules. For example, the resource set with the smaller index uses the conflicting resources.

[0098] Figure 8 800 is an exemplary block diagram of a hardware platform 800, which may be part of a network device (e.g., a base station) or a communication device (e.g., a user equipment (UE)). The hardware platform 800 includes at least one processor 810 and a memory 805 storing instructions. The instructions executed by the processor 810 configure the hardware platform 800 to perform Figures 1 to 7As well as the operations described in the various embodiments described in this patent application. Transmitter 815 transmits or sends information or data to another device. For example, a network device transmitter can send a message to a user device. Receiver 820 receives information or data transmitted or sent by another device. For example, a user device can receive a message from a network device.

[0099] The above implementation will be applied to network communication. Fig. 9 An example of a communication system (e.g., a 6G or NR cellular network) including a base station 920 and one or more user equipments (UEs) 911, 912, and 913 is shown. In some embodiments, the UE uses a communication link to the network (sometimes referred to as an uplink direction, as shown by dashed arrows 931, 932, 933) to access the BS (e.g., the network), which then enables subsequent communication from the BS to the UE (e.g., shown in the direction from the network to the UE, sometimes referred to as a downlink direction, as shown by arrows 941, 942, 943). In some embodiments, the BS sends information to the UE (sometimes referred to as a downlink direction, as shown by arrows 941, 942, 943), which then enables subsequent communication from the UE to the BS (e.g., shown in the direction from the UE to the BS, sometimes referred to as an uplink direction, as shown by dashed arrows 931, 932, 933). The UE can be, for example, a smartphone, a tablet, a mobile computer, a machine-to-machine (M2M) device, an Internet of Things (IoT) device, etc.

In ISAC or other communication systems, time-frequency resources need to be shared between sensing and communication. Periodic broadband resource allocation of sensing signals will consume resources. Therefore, ISAC needs a more flexible way to allocate sensing signals.
