Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the field of communication technology, and in particular to a configuration method, apparatus, device and storage medium for a resource set. Background Art
[0002] With the continuous evolution and support of wireless communication technology, IoT (Internet of Things) technology is also developing rapidly. At present, 3GPP (3rd Generation Partnership Project) is organizing and promoting the development of MTC (Machine Type Communication) / eMTC (enhanced Machine Type Communication) and NB-IoT (Narrow Band Internet of Things) series standards, which will also become candidate technical standards for 5G (5th-Generation) massive machine communication (massive MTC) technology.
[0003] MTC / eMTC terminal equipment and NB-IoT terminal equipment have technical advantages such as low cost, support for ultra-low power consumption, and support for deep and wide coverage scenarios. However, since the design goal of MTC / eMTC terminal equipment and NB-IoT terminal equipment is to support application scenarios with low data transmission rate and high data transmission delay, MTC / eMTC terminal equipment and NB-IoT terminal equipment cannot be used in some IoT application scenarios that require high data transmission rate, such as video surveillance in smart security, industrial applications with low latency, etc. However, if NR (Newradio, new air interface) terminal equipment is directly used in these application scenarios, the design indicators of NR terminal equipment (such as transmission rate, transmission delay, etc.) far exceed the actual needs of these scenarios, so the cost is high, which is not conducive to promotion and use. Therefore, in order to improve the terminal equipment system for 5G large-scale machine communication scenarios, it is necessary to design a type of terminal equipment that supports medium transmission rate, medium latency requirements, and low cost. Research results in related technologies have shown that reducing the number of RF channels that terminal equipment needs to be equipped with can significantly reduce the cost of terminal equipment. However, although reducing the number of RF channels of terminal devices can effectively reduce the cost of terminal devices, the reduction in the number of receiving antennas will also affect the receiving performance of the terminal devices, further affecting the downlink coverage of network devices.
[0004] Therefore, how to design the signal transmission mechanism to reduce the impact of the number of RF channels of terminal devices on the downlink coverage of network devices requires further discussion and research. Summary of the invention

[0039] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0040] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person of ordinary skill in the art can appreciate that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.
[0041] Please refer to Figure 1 , which shows a schematic diagram of a system architecture provided by an embodiment of the present application. The system architecture may include: a terminal device 10 and a network device 20.
[0042] The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 may be distributed in a cell managed by each network device 20. The terminal device 10 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), etc. For the convenience of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as terminal devices.
[0043] The network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with network device functions may be different. For example, in a 5G NR system, it is called gNodeB or gNB. With the evolution of communication technology, the name "network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as network devices.
[0044] The "5G NR system" in the embodiment of the present application may also be referred to as a 5G system or an NR system, but those skilled in the art may understand its meaning. The technical solution described in the embodiment of the present application may be applicable to a 5G NR system, or to a subsequent evolution system of the 5G NR system, such as an MTC / eMTC system, an NB-IoT system, a 6G (6-Generation, 6th generation mobile communication technology) system, etc.
[0045] At present, with the continuous evolution and support of wireless communication technology, IoT technology is also developing rapidly. 3GPP is organizing and promoting the development of MTC / eMTC and NB-IoT series standards, which will also become candidate technical standards for 5G large-scale machine communication technology. In the subsequent technological evolution and development, these technical standards are expected to play a huge role in smart homes, smart cities, smart factories, remote monitoring, smart transportation and other aspects related to human production and life.
[0046] Compared with the terminal equipment in the NR system (hereinafter referred to as "NR terminal equipment" in the embodiment of the present application), the terminal equipment in the MTC / eMTC system (hereinafter referred to as "MTC / eMTC terminal equipment" in the embodiment of the present application) and the terminal equipment in the NB-IoT system (hereinafter referred to as "NB-IoT terminal equipment" in the embodiment of the present application) have technical advantages such as low cost, support for ultra-low power consumption, and support for deep and wide coverage scenarios. Therefore, MTC / eMTC terminal equipment and NB-IoT terminal equipment are conducive to rapid popularization in the early stage of the development of Internet of Things technology. However, since the design goal of NB-IoT terminal equipment is to support application scenarios with low data transmission rates and high data transmission delays, NB-IoT terminal equipment cannot be used in some Internet of Things application scenarios that require high data transmission rates, such as video surveillance in smart security, industrial applications that require low latency, and other application scenarios. However, if NR terminal equipment is directly used in these application scenarios, the design indicators of NR terminal equipment (such as transmission rate, transmission delay, etc.) far exceed the actual needs of these scenarios, so the cost is high, which is not conducive to promotion and use.
[0047] Therefore, in order to improve the terminal equipment system in the 5G large-scale machine communication scenario, it is necessary to design a type of terminal equipment that supports medium transmission rate, medium latency requirements and low cost. At present, NR terminal equipment needs to support at least 2 receiving channels, and in some frequency bands, NR terminal equipment needs to support 4 receiving channels. Among them, each receiving channel includes components such as receiving antennas, filters, PA (Power Amplifier), samplers, etc., so reducing the number of RF channels that NR terminal equipment needs to be equipped with will significantly reduce the cost of terminal equipment. Research results in related technologies have shown that by reducing the two RF channels in the terminal equipment to one RF channel, the cost of the chip module of the terminal equipment can be reduced by about one third.
[0048] However, although reducing the number of RF channels of terminal devices can effectively reduce the cost of terminal devices, the reduction in the number of receiving antennas will also affect the receiving performance of terminal devices, further affecting the downlink coverage of network devices. For example, if the number of receiving antennas of terminal devices is reduced by half (such as from 2 receiving antennas to 1 receiving antenna), the terminal device will lose about 3dB in receiving the downlink channel. Therefore, in order to compensate for the impact of reducing the number of RF channels of terminal devices on the downlink coverage of network devices, it is necessary to design a new signal transmission mechanism to compensate and restore the loss of downlink coverage (Coverage) of network devices. In addition, in some scenarios (such as industrial monitoring scenarios), the communication module of the terminal device may be placed in an area blocked by metal objects (such as robotic arms). Therefore, the signal transmitted by the network device will be further lost. For such working scenarios, it is also necessary to design a coverage enhancement (Coverage Enhancement) solution to compensate for the performance loss. Studies in related technologies have shown that repeated transmission is a typical and effective coverage enhancement solution. For example, theoretically, two repeated transmissions can bring a 3dB combined gain compared to a single transmission, and ten repeated transmissions can bring a 10dB combined gain compared to a single transmission.
[0049] The downlink control information sent by the network device to the terminal device is carried in the PDCCH (Physical Downlink Control Channel). The terminal device detects the downlink control information (or monitors the PDCCH) in the PDCCH Search Space and the Control Resource Set (CORESET). The following is an introduction to the contents related to PDCCH Search Space and CORESET.
[0050] First, the PDCCH Search Space is introduced.
[0051] The terminal device monitors the PDCCH in the PDCCH Search Space. In one example, the network device can configure a maximum of 10 PDCCH Search Spaces for the terminal. Optionally, the network device notifies the terminal of the PDCCH Search Space through RRC (Radio Resource Control) signaling. In one example, the configuration information of the PDCCH Search Space includes the following:
[0052] Search ID
[0053] ControlResourceSetId (control resource set identifier, used to indicate the ID of the configuration information of CORESET, and then configure the time and frequency resources of PDCCH Search Space);
[0054] The monitoring time slot period and the monitoring offset within the period (currently NR supports monitoring time slot periods of 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, 160, 320, 640, 1280, and 2560 time slots).
[0055] Duration (duration, used to indicate the number of time slots monitored continuously within the PDCCH Search Space period);
[0056] MonitoringSymbolsWithinSlot (monitoring symbols within a time slot, used to indicate which symbols within a monitoring time slot are used to monitor the PDCCH);
[0057] PDCCH candidates (PDCCH candidate set, used to indicate the configuration information of PDCCH candidates (candidate PDCCH));
[0058] Search Space Type (used to indicate whether the PDCCH Search Space is CSS (Common Search Space) or USS (UE Search Space)).
[0059] Next, CORESET is introduced.
[0060] In the 5G NR system, the concept of control resource set is introduced. CORESET is used to define a set of time-frequency resources that carry control information. The terminal device can monitor PDCCH in the time-frequency resources indicated by CORESET to obtain scheduling information, etc. The configuration information of CORESET includes at least one of the following: information on frequency domain resources, information on time domain resources, time length information, etc. In addition, the configuration information of CORESET also includes TCI (Transmission Configuration Indication) state (State), which is used to indicate the QCL (Quasi-Co-Location) information of the DMRS (DeModulation Reference Signal) antenna port used to send PDCCH in the CORESET. Among them, the QCL information can be represented by means of the QCL relationship between the downlink reference signal. Optionally, the downlink reference signal can be SS (SS (Synchronization Signal) / PBCH (Physical Broadcast Channel) Blocks, hereinafter referred to as "SSB"), or CSI-RS (Channel State Information Reference Signal, channel state information measurement reference signal).
[0061] For example, if the receiving port of the PDCCH transmitted in the control resources indicated by CORESET has a QCL relationship with the receiving port of SSB 1 (SSBindex is 1), the TCI state can be used to indicate the QCL relationship between the receiving port of the PDCCH and the receiving port of SSB 1. If the receiving port of the PDCCH transmitted in the control resources indicated by CORESET has a QCL relationship with the receiving port of SSB 2 (SSB index is 2), the TCI state can be used to indicate the QCL relationship between the receiving port of the PDCCH and the receiving port of SSB 2. If there are N antenna ports used to send N SSBs respectively, and N is a positive integer, there will be a QCL set, which includes N QCL information, namely, the QCL information of SSB 1, the QCL information of SSB 2, ..., the QCL information of SSB N. The TCI state of the CORESET can indicate the QCL information of one of the N SSBs, so that the terminal device receives the PDCCH in the control resources indicated by the CORESET based on the QCL information of the SSB, that is, the terminal device can assume that there is a QCL relationship between the receiving port of the PDCCH and the receiving port of the SSB.
[0062] Finally, CCE (Control Channel Elements) is introduced.
[0063] For a Search Space s associated with a CORESET p, in the time slot Corresponding carrier domain value n CI , corresponding to the PDCCH candidate with aggregation level L The CCE number is given by the following formula:
[0064]
[0065] For CSS, For USS, For p mod 3 = 1, A p =39829; for p mod 3 = 2, A p =39839 and D = 65537. i = 0, ..., L-1. N CCE,p is the number of CCEs in CORESET p, numbered from 0 to N CCE,p -1.n CI The value of the carrier indication field when the terminal device is configured with the carrier indication field by CrossCarrierSchedulingConfig. Otherwise, n CI =0. in Configured pair carrier n CI And the number of PDCCH candidate positions with aggregation level L monitored on Search Spaces. For CSS, Corresponding to USS, is in all configurations n CI The value corresponds to the maximum aggregation level L monitored on Search Space s. n RNTI The RNTI (Radio Network Temporary Identifier) value used is C-RNTI (Cell Radio Network Temporary Identifier).
[0066] From the above introduction, it can be seen that for NR terminal devices, each channel of NR has the need for coverage compensation (Coverage Recovery) or coverage enhancement (Coverage Enhancement). In the related technology, the NR terminal device only supports a larger aggregation level (Aggregation Levels, AL) for coverage enhancement, such as AL = 16. However, the effect of achieving coverage enhancement by increasing the supported aggregation level is relatively limited. Therefore, how to further reduce the impact of the terminal device's RF channel data on the downlink coverage of the network device, and further perform coverage compensation and coverage enhancement, still needs further discussion and research.
[0067] Based on this, an embodiment of the present application provides a method for configuring a resource set, which can be used to further achieve coverage enhancement. The technical solution of the present application is introduced and explained through several exemplary embodiments.
[0068] Please refer to Figure 2 , which shows a flowchart of a method for configuring a resource set provided by an embodiment of the present application, which method can be applied to Figure 1 In the system architecture shown, the method may include the following steps:
[0069] Step 210: The network device sends configuration information to the terminal device, where the configuration information is used to configure n repeated control channel resource sets in a single time slot, where n is an integer greater than 1.
[0070] From the above introduction, it can be seen that the control channel resources that carry the information transmitted between the network device and the terminal device can be indicated by a control channel resource set. In order for the terminal device to clearly understand the time-frequency position and other information of the control channel resources, the network device needs to send configuration information to the terminal device before sending the communication information to configure the control channel resource set. Furthermore, the network device can send PDCCH to the terminal device based on the control channel resources indicated by the control channel resource set, and the terminal device can detect the PDCCH from the network device based on the control channel resources indicated by the control channel resource set, that is, the terminal device monitors the PDCCH based on the control channel resources indicated by the control channel resource set.
[0071] In order to achieve the purpose of coverage enhancement and ensure that there are sufficient control channel resources between the network device and the terminal device to carry the repeatedly transmitted communication information, the network device needs to configure multiple control channel resource sets. Considering the complexity of the design of the control channel resource set, the network device can configure multiple repeated control channel resource sets to repeatedly transmit communication information. In the related art, a control channel resource set is configured in a time slot. On this basis, multiple repeated control channel resource sets can be configured in multiple time slots, that is, the control channel resource set configured in a time slot in the related art is repeated in multiple time slots.
[0072] However, the effect of coverage enhancement that can be achieved by repeating a control channel resource set in multiple time slots is also relatively limited. In order to further enhance coverage, an embodiment of the present application proposes to configure n repeated control channel resource sets in a single time slot, where n is an integer greater than 1. In an embodiment of the present application, a network device sends configuration information to a terminal device, and the configuration information is used to configure n repeated control channel resource sets in a single time slot, that is, to repeat a control channel resource set originally configured in a time slot in a single time slot. Optionally, the configuration information is carried in a system message or RRC dedicated signaling, and the embodiment of the present application does not limit the carrying method of the configuration information.
[0073] For example, Figure 3 As shown, Figure 3 (a) shows an example of configuring a control channel resource set in a time slot in the related art. Figure 3 (b) shows an example of configuring two repeated control channel resource sets in one time slot in an embodiment of the present application. Optionally, the configuration of n repeated control channel resource sets in a single time slot proposed in an embodiment of the present application can be used in combination with the scheme of configuring multiple repeated control channel resource sets in multiple time slots, so as to achieve a better coverage enhancement effect. Optionally, considering the demodulation performance of the control channel, the time domain positions of the multiple repeated control channel resource sets in the embodiment of the present application do not overlap.
[0074] The embodiments of the present application do not limit how the configuration information sent by the network device configures the n repeated control channel resources. In one example, the configuration information is used to indicate n repeated control channel resource sets, that is, each control channel resource set is regarded as an independent individual, and the n control channel resource sets indicated by the configuration information are repeated independent individuals; in another example, the configuration information is used to indicate a third control channel resource set, and the third control channel resource set includes n repeated control channel resource sets, that is, the n control channel resource sets are regarded as a whole, namely, the third control channel resource set, and this whole is obtained by repeating the control channel resource set.
[0075] The embodiments of the present application do not limit the content of the configuration information. In one example, the configuration information includes: first information and second information. The first information is used to indicate a reference control channel resource set of n control channel resource sets, and the reference control channel resource set is the configuration basis of the n control channel resource sets, that is, the n control channel resource sets are obtained by repeating the reference control channel resource set; the second information is used to indicate the number of repetitions n of the control channel resource set. Optionally, the n repeated control channel resource sets are obtained by repeating the reference control channel resource set n times. Optionally, without considering the signaling overhead, the network device may also send two configuration information to the terminal device, one configuration information is used to indicate the reference control channel resource, and the other configuration information is used to indicate the number of repetitions n.
[0076] In summary, the technical solution provided by the embodiment of the present application configures multiple control channel resource sets in a single time slot, so that the control channel resource set occupies more time domain resources in a single time slot, so that the communication information between the network device and the terminal device can occupy more control channel resources for transmission, thereby improving the transmission performance of the control channel. Since the communication information occupies more control channel resources for transmission, it is convenient to achieve the purpose of repeated transmission of the communication information. Through repeated transmission, the impact of the number of radio frequency channels of the terminal device on the downlink coverage of the network device can be reduced, thereby achieving the purpose of enhanced coverage. Moreover, in the embodiment of the present application, the multiple control channel resource sets configured in a single time slot are repeated control channel resource sets. When configuring multiple control channel resource sets, only one control channel resource set needs to be designed, and the design of other control channel resource sets can directly follow the design of the control channel resource set, so that the design in each control channel resource set can follow the design of the control channel resource set in the related technology, which simplifies the standard design and reduces the complexity of the terminal device implementation. In addition, in the embodiments of the present application, since the design within each control channel resource set can follow the design of the control channel resource set in the related technology, not only can the terminal equipment with enhanced coverage after the communication protocol is updated use the control channel resource set indicated by the configuration information, but the terminal equipment before the communication protocol is updated can also use the control channel resource set indicated by the configuration information, thereby achieving the sharing of control channel resources by the two and improving resource reuse and utilization efficiency.
[0077] The time-frequency resources occupied by n repeated control channel resource sets are introduced and explained below.
[0078] First, the frequency resources occupied by n repeated control channel resource sets are introduced.
[0079] In one example, the first control channel resource set among n control channel resource sets occupies a first frequency resource, and the second control channel resource set occupies a second frequency resource; wherein the first frequency resource is the same as the second frequency resource; or, the first frequency resource is different from the second frequency resource.
[0080] The first control channel resource set and the second control channel resource set are any control channel resource sets with different time domain positions in the n control channel resource sets, respectively. They can be two control channel resource sets that are continuous in the time domain among the n control channel resource sets, or they can be two control channel resource sets that are discontinuous in the time domain among the n control channel resource sets. For example, there is one control channel resource set between the first control channel resource set and the second control channel resource set, which is not limited in the embodiments of the present application. The following is an introduction and explanation taking the first control channel resource set and the second control channel resource set as two control channel resource sets that are continuous in the time domain among the n control channel resource sets as an example.
[0081] In the embodiment of the present application, the first control channel resource set occupies the first frequency resource, and the second control channel resource set occupies the second frequency resource. The first frequency resource and the second frequency resource may be the same frequency resource or different frequency resources. It should be noted that since the first control channel resource set and the second control channel resource set are repeated control channel resource sets, although the frequency resources they occupy may be different, the bandwidth they occupy is the same. Figure 4 (a) and Figure 4 As shown in (b), the first control channel resource set and the second control channel resource set occupy the same bandwidth. Figure 4 (a) shows the case where the frequency resources occupied by the first control channel resource set and the second control channel resource set are the same. Figure 4 (b) shows the situation where the frequency resources occupied by the first control channel resource set and the second control channel resource set are different.
[0082] By making the first frequency resource and the second frequency resource the same, that is, the first control channel resource and the second control channel resource occupy the same frequency resource, it is possible to ensure that the terminal device can receive and demodulate the control channel without the need for frequency hopping, thereby simplifying the implementation of the terminal device. By making the first frequency resource and the second frequency resource different, that is, the first control channel resource and the second control channel resource occupy different frequency resources, frequency diversity gain and randomization of interference can be obtained, thereby improving the transmission performance of the control channel. In actual applications, whether the first frequency resource and the second frequency resource are the same can be flexibly determined in combination with the needs of the application.
[0083] Optionally, when the first frequency resource is different from the second frequency resource, the configuration information also includes a frequency offset between the first frequency resource and the second frequency resource. In order to enable the terminal device to clearly understand the frequency offset between the first frequency resource and the second frequency resource, the embodiment of the present application also encapsulates the frequency offset into the configuration information, thereby reducing the signaling exchanges between the network device and the terminal device. Of course, without considering the signaling overhead between the terminal device and the network device, the frequency offset can also be sent to the terminal device through a separate signaling. In one example, the frequency offset can also be predefined by a communication protocol; or, the frequency offset is determined by negotiation between the terminal device and the network device, which is not limited in the embodiment of the present application. Optionally, when the frequency offset is configured by the network device, the network device can determine the specific frequency offset in combination with factors such as network bandwidth.
[0084] The embodiment of the present application does not limit the specific implementation of the frequency offset. Optionally, the frequency offset is the offset between the reference point in the first frequency resource and the reference point in the second frequency resource. The relative position of the reference point in the first frequency resource in the first frequency resource is the same as the relative position of the reference point in the second frequency resource in the second frequency resource. Figure 4 As shown in (b), the reference point is the lowest frequency point of the frequency resource, so that the frequency offset is the offset between the lowest frequency point of the first frequency resource and the lowest frequency point of the second frequency resource. Optionally, the reference point can also be the frequency center point of the frequency resource, or the highest frequency point of the frequency resource, or any point in the frequency resource, which is not limited in the embodiments of the present application.
[0085] Secondly, the time domain resources occupied by n repeated control channel resource sets are introduced.
[0086] In one example, symbols occupied by two adjacent control channel resource sets among the n control channel resource sets are continuous in the time domain; or, symbols occupied by two adjacent control channel resource sets among the n control channel resource sets are discontinuous in the time domain.
[0087] In order to ensure the demodulation performance of the terminal equipment and avoid mutual interference between the control channel resources indicated by different control channel resource sets, in an embodiment of the present application, the time domain resources occupied by two adjacent control channel resource sets among the n control channel resource sets do not overlap. Exemplarily, an embodiment of the present application represents the time domain resources occupied by a control channel resource set by the symbols occupied by the control channel resource set. Optionally, the symbols occupied by the control channel resource set are OFDM (Orthogonal Frequency Division Multiplexing) symbols. Optionally, the symbols occupied by two adjacent control channel resource sets may be continuous in the time domain or discontinuous in the time domain. One point that needs to be explained is that since two adjacent control channel resource sets are repeated control channel resource sets, the number of symbols they occupy is the same. As Figure 4 As shown in (a), it shows that the symbols occupied by two adjacent control channel resource sets are continuous, as shown in Figure 4 As shown in (c), it shows that the symbols occupied by two adjacent control channel resource sets are not continuous.
[0088] The embodiment of the present application does not limit the number of symbols occupied by a single control channel resource set. Optionally, the number of symbols occupied by a single control channel resource set is greater than 3 symbols. For example, the number of symbols occupied by a single control channel resource set is 4 symbols, or 5 symbols, or 6 symbols. Figure 5 As shown in (a), in the related art, the number of symbols occupied by a single control channel resource set is 3 symbols, such as Figure 5 As shown in (b), in the embodiment of the present application, the number of symbols occupied by a single control channel resource set is 6. By expanding the number of symbols occupied by a single control channel resource set, the coding rate of the control channel can be reduced and the transmission performance of the control channel can be improved.
[0089] By making the symbols occupied by two adjacent control channel resource sets continuous in the time domain, it is possible to ensure that the terminal device continuously receives and demodulates the control channel. By making the symbols occupied by two adjacent control channel resource sets discontinuous in the time domain, the terminal device can receive other communication information in the gap between receiving and demodulating the control channel, thereby optimizing the performance of the communication system. In practical applications, whether the symbols occupied by two adjacent control channel resource sets are continuous in the time domain can be flexibly determined in combination with application requirements.
[0090] Optionally, when the symbols occupied by two adjacent control channel resource sets among n control channel resource sets are discontinuous in the time domain, the configuration information also includes the number of interval symbols between the symbols occupied by two adjacent control channel resource sets. In order to enable the terminal device to clearly understand the time domain offset between two adjacent control channel resource sets, the embodiment of the present application also encapsulates the number of interval symbols between two adjacent control channel resource sets into the configuration information, thereby reducing the signaling exchanges between the network device and the terminal device. Of course, without considering the signaling overhead between the terminal device and the network device, the number of interval symbols can also be sent to the terminal device through a separate signaling. In one example, the number of interval symbols can also be predefined by the communication protocol; or, the number of interval symbols is determined by negotiation between the terminal device and the network device, which is not limited by the embodiment of the present application.
[0091] The embodiment of the present application does not limit the specific implementation of the number of interval symbols. Optionally, the number of interval symbols is the offset between the reference points in two adjacent control channel resource sets. Assuming that the first control channel resource set and the second control channel resource set are two adjacent control channel resource sets, the relative position of the reference point in the first control channel resource set in the first control channel resource set is the same as the relative position of the reference point in the second control channel resource set in the second control channel resource set. For example, Figure 4 As shown in (c), the reference point is the starting symbol of the control channel resource set, so the number of interval symbols is the number of interval symbols between the starting symbol of the first control channel resource set and the starting symbol of the second control channel resource set. Optionally, the reference point can also be a middle symbol in the control channel resource set, or a last symbol in the control channel resource set, which is not limited in the embodiment of the present application.
[0092] In summary, the technical solution provided by the embodiment of the present application can ensure that the terminal device can receive and demodulate the control channel without the need for frequency hopping by having multiple control channel resource sets occupy the same frequency resources, thereby simplifying the implementation of the terminal device. By having multiple control channel resource sets occupy different frequency resources, frequency diversity gain and randomization of interference can be obtained, thereby improving the transmission performance of the control channel. By having the symbols occupied by multiple control channel resource sets continuous in the time domain, it can be ensured that the terminal device continuously receives and demodulates the control channel. By having the symbols occupied by multiple control channel resource sets discontinuous in the time domain, the terminal device can receive other communication information in the gap between receiving and demodulating the control channel, thereby optimizing the performance of the communication system.
[0093] The following describes the TCI status in n repeated control channel resource sets.
[0094] In one example, the TCI states of the n control channel resource sets are the same; or, the TCI states of at least two control channel resource sets among the n control channel resource sets are different.
[0095] As can be seen from the above introduction, TCI status refers to the QCL information of the DMRS antenna port used by PDCCH. TCI status is also an important indicator for the terminal device to receive communication information. Through TCI status, the terminal device can obtain the QCL relationship between the DMRS antenna port and the downlink reference signal. Optionally, the downlink reference signal can be SSB or CSI-RS.
[0096] In an embodiment of the present application, n repeated control channel resource sets are configured in a single time slot, and the TCI states in the n repeated control channel resource sets may be the same, so that it is only necessary to configure the TCI state of the above-mentioned reference control channel resource set, and the TCI states of other control channel resource sets in the n control channel resource sets repeat the TCI state of the reference control channel resource set, thereby simplifying the standard design. Alternatively, the TCI states in the n repeated control channel resource sets may be different, so it is necessary to separately configure the corresponding TCI states for control channel resource sets with different TCI states. By using different TCI states for different control channel resource sets, spatial diversity gain can be achieved, so that even if the performance of some control channel resource sets is poor (for example, the beam is blocked), other control channel resource sets can be used to obtain stable control channel transmission performance, thereby effectively combating channel fading.
[0097] Take the QCL relationship between the TCI status indication DMRS antenna port and SSB as an example, Figure 6 As shown in (a), the TCI states in the multiple control channel resource sets all indicate the QCL relationship between the DMRS antenna port and SSB 2, that is, the DMRS antenna port and SSB 2 satisfy the Type D QCL relationship. Figure 6 As shown in (b), the TCI status in multiple control channel resource sets indicates the QCL relationship between the DMRS antenna port and different SSBs. The TCI status in the first control channel resource set indicates that the DMRS antenna port satisfies the QCL relationship of Type D with SSB 2, the TCI status in the second control channel resource set indicates that the DMRS antenna port satisfies the QCL relationship of Type D with SSB 3, and the TCI status in the third control channel resource set indicates that the DMRS antenna port satisfies the QCL relationship of Type D with SSB 5.
[0098] One point that needs to be explained is that the TCI states in the n control channel resource sets in the embodiment of the present application are different, including that the TCI in some control channel resource sets in the n control channel resource sets are the same, and the TCI states in some control channel resource sets are different; or, the TCI state in each control channel resource set in the n control channel resource sets is different.
[0099] Optionally, when the TCI states of at least two of the n control channel resource sets are different, the configuration information also includes the TCI states of the at least two control channel resource sets. In order to enable the terminal device to clearly understand the TCI states in different control channel resource sets, in the embodiment of the present application, when the TCI states of at least two of the n control channel resource sets are different, that is, when there are different TCI states in the n control channel resource sets, the TCI states of at least two control channel resource sets are encapsulated into the configuration information, thereby reducing the signaling exchanges between the network device and the terminal device. Of course, without considering the signaling overhead between the terminal device and the network device, the TCI states in different control channel resource sets can also be sent to the terminal device through a separate signaling. In one example, the TCI states in different control channel resource sets can also be predefined by the communication protocol, which is not limited by the embodiment of the present application.
[0100] In summary, the technical solution provided by the embodiment of the present application uses the same TCI state for multiple control channel resource sets repeated in a single time slot, so that only one TCI state of the control channel resource set can be designed, and other control channel resource sets can reuse the TCI state, thereby simplifying the design of the control channel resource set. By using different TCI states for multiple control channel resource sets repeated in a single time slot, spatial diversity gain can be achieved, so that even if some control channel resource sets have poor performance due to beam obstruction, other control channel resource sets can be used to obtain stable control channel transmission performance, thereby effectively combating channel fading.
[0101] The following describes the influence of the number of repetitions n on the number of repeated transmissions of the PDCCH.
[0102] In one example, the method further includes the following steps:
[0103] Step 220: The network device sends a PDCCH to the terminal device based on the control channel resources indicated by the n control channel resource sets.
[0104] After configuring n control channel resource sets repeated in a single time slot, the network device can send PDCCH to the terminal device based on the control channel resources indicated by the n control channel resource sets, that is, send communication information to the terminal device on the control channel resources indicated by the n control channel resource sets, or it can be said that the communication information is carried on the control channel resources indicated by the n control channel resource sets. Optionally, the PDCCH transmitted by the network device on the control channel resources indicated by the n control channel resource sets is repeated, that is, the communication information carried in the PDCCH is repeated, so that the purpose of coverage enhancement is achieved through repeated transmission.
[0105] Step 230: The terminal device monitors the PDCCH based on the control channel resources indicated by the n control channel resource sets.
[0106] Since the network device sends configuration information to the terminal device, the terminal device also specifies the n control channel resource sets repeated in a single time slot. During the communication process, the terminal device monitors the PDCCH based on the control channel resources indicated by the n control channel resource sets, that is, the communication information from the network device is detected on the control channel resources indicated by the n control channel resource sets, or it can be said that the communication information is carried on the control channel resources indicated by the n control channel resource sets.
[0107] In the embodiment of the present application, the network device can achieve the purpose of coverage enhancement by repeatedly transmitting the PDCCH. When determining the number of repeated transmissions of the PDCCH, the number of repetitions n of the control channel resource set can be included in the number of repeated transmissions of the PDCCH, or the number of repetitions n of the control channel resource set can be excluded from the number of repeated transmissions of the PDCCH. In practical applications, whether the number of repetitions n is included in the number of repeated transmissions of the PDCCH can be determined by negotiation between the terminal device and the network device; it can also be pre-configured by the network device; it can also be pre-defined by the communication protocol, etc., and the embodiment of the present application does not limit this.
[0108] For example, assuming that the PDCCH needs to be transmitted repeatedly 10 times and the repetition number n of the control channel resource set is 2, then when the repetition number n is included in the number of repeated transmissions of the PDCCH, the network device needs to transmit the PDCCH in 5 control channel resource sets including 2 repetitions (that is, the third control channel resource set mentioned above); when the repetition number n is not included in the number of repeated transmissions of the PDCCH, the network device needs to transmit the PDCCH in 10 control channel resource sets including 2 repetitions (that is, the third control channel resource set mentioned above).
[0109] To summarize, the technical solution provided by the embodiments of the present application provides several schemes for determining the number of repeated transmissions of the control channel between the network device and the terminal device. Since whether the number of repetitions of the control channel resource set within a single time slot is included in the number of repeated transmissions of the control channel, the impact on the time domain resources occupied by the repeated transmission control channel is different, the embodiments of the present application improve the flexibility of determining the time domain resources occupied by repeated transmissions.
[0110] It should be noted that in the above method embodiment, the configuration method of the resource set provided by the present application is mainly introduced and explained from the perspective of the interaction between the terminal device and the network device. The above steps performed by the terminal device can be independently implemented as a configuration method of the resource set on the terminal device side; the above steps performed by the network device can be independently implemented as a configuration method of the resource set on the network device side.
[0111] The following is an embodiment of the device of the present application, which can be used to execute the embodiment of the method of the present application. For details not disclosed in the embodiment of the device of the present application, please refer to the embodiment of the method of the present application.
[0112] Please refer to Figure 7 , which shows a block diagram of a resource set configuration device provided by an embodiment of the present application. The device has the function of implementing the above-mentioned terminal device side method example, and the function can be implemented by hardware, or by hardware executing corresponding software. The device can be the terminal device described above, or it can be set in the terminal device. Figure 7 As shown, the device 700 may include: a configuration information receiving module 710.
[0113] The configuration information receiving module 710 is used to receive configuration information from a network device, where the configuration information is used to configure n repeated control channel resource sets in a single time slot, where n is an integer greater than 1.
[0114] In one example, the configuration information includes: first information for indicating a reference control channel resource set of the n control channel resource sets; and second information for indicating a repetition number n of the control channel resource set.
[0115] In one example, the n repeated control channel resource sets are obtained by repeating the reference control channel resource set n times.
[0116] In one example, the first control channel resource set among the n control channel resource sets occupies a first frequency resource, and the second control channel resource set occupies a second frequency resource; wherein the first frequency resource is the same as the second frequency resource; or, the first frequency resource is different from the second frequency resource.
[0117] In one example, when the first frequency resource is different from the second frequency resource, the configuration information also includes a frequency offset between the first frequency resource and the second frequency resource.
[0118] In one example, the symbols occupied by two adjacent control channel resource sets among the n control channel resource sets are continuous in the time domain; or, the symbols occupied by two adjacent control channel resource sets among the n control channel resource sets are discontinuous in the time domain.
[0119] In one example, when the symbols occupied by two adjacent control channel resource sets among the n control channel resource sets are not continuous in the time domain, the configuration information also includes the number of interval symbols between the symbols occupied by the two adjacent control channel resource sets.
[0120] In one example, the TCI states of the n control channel resource sets are the same; or, the TCI states of at least two control channel resource sets among the n control channel resource sets are different.
[0121] In one example, when the TCI states of at least two control channel resource sets among the n control channel resource sets are different, the configuration information also includes the TCI states of the at least two control channel resource sets.
[0122] In one example, if Figure 8 As shown, the apparatus 700 further includes: a monitoring module 720, configured to monitor the PDCCH based on the control channel resources indicated by the n control channel resource sets.
[0123] In one example, the number of repetitions n is counted in the number of repeated transmissions of the PDCCH; or, the number of repetitions n is not counted in the number of repeated transmissions of the PDCCH.
[0124] In one example, the configuration information is used to indicate the n repeated control channel resource sets.
[0125] In one example, the configuration information is used to indicate a third control channel resource set, and the third control channel resource set includes the n repeated control channel resource sets.
[0126] In summary, the technical solution provided by the embodiment of the present application configures multiple control channel resource sets in a single time slot, so that the control channel resource set occupies more time domain resources in a single time slot, so that the communication information between the network device and the terminal device can occupy more control channel resources for transmission, thereby improving the transmission performance of the control channel. Since the communication information occupies more control channel resources for transmission, it is convenient to achieve the purpose of repeated transmission of the communication information. Through repeated transmission, the impact of the number of radio frequency channels of the terminal device on the downlink coverage of the network device can be reduced, thereby achieving the purpose of enhanced coverage. Moreover, in the embodiment of the present application, the multiple control channel resource sets configured in a single time slot are repeated control channel resource sets. When configuring multiple control channel resource sets, only one control channel resource set needs to be designed, and the design of other control channel resource sets can directly follow the design of the control channel resource set, so that the design in each control channel resource set can follow the design of the control channel resource set in the related technology, which simplifies the standard design and reduces the complexity of the terminal device implementation. In addition, in the embodiments of the present application, since the design within each control channel resource set can follow the design of the control channel resource set in the related technology, not only can the terminal equipment with enhanced coverage after the communication protocol is updated use the control channel resource set indicated by the configuration information, but the terminal equipment before the communication protocol is updated can also use the control channel resource set indicated by the configuration information, thereby achieving the sharing of control channel resources by the two and improving resource reuse and utilization efficiency.
[0127] Please refer to Fig. 9 , which shows a block diagram of a configuration device for a resource set provided by an embodiment of the present application. The device has the function of implementing the above network device side method example, and the function can be implemented by hardware or by hardware executing corresponding software. The device can be the network device described above, or it can be set in the network device. Fig. 9 As shown, the device 900 may include: a configuration information sending module 910.
[0128] The configuration information sending module 910 is used to send configuration information to the terminal device, where the configuration information is used to configure n repeated control channel resource sets in a single time slot, where n is an integer greater than 1.
[0129] In one example, the configuration information includes: first information for indicating a reference control channel resource set of the n control channel resource sets; and second information for indicating a repetition number n of the control channel resource set.
[0130] In one example, the n repeated control channel resource sets are obtained by repeating the reference control channel resource set n times.
[0131] In one example, the first control channel resource set among the n control channel resource sets occupies a first frequency resource, and the second control channel resource set occupies a second frequency resource; wherein the first frequency resource is the same as the second frequency resource; or, the first frequency resource is different from the second frequency resource.
[0132] In one example, when the first frequency resource is different from the second frequency resource, the configuration information also includes a frequency offset between the first frequency resource and the second frequency resource.
[0133] In one example, the symbols occupied by two adjacent control channel resource sets among the n control channel resource sets are continuous in the time domain; or, the symbols occupied by two adjacent control channel resource sets among the n control channel resource sets are discontinuous in the time domain.
[0134] In one example, when the symbols occupied by two adjacent control channel resource sets among the n control channel resource sets are not continuous in the time domain, the configuration information also includes the number of interval symbols between the symbols occupied by the two adjacent control channel resource sets.
[0135] In one example, the TCI states of the n control channel resource sets are the same; or, the TCI states of at least two control channel resource sets among the n control channel resource sets are different.
[0136] In one example, when the TCI states of at least two control channel resource sets among the n control channel resource sets are different, the configuration information also includes the TCI states of the at least two control channel resource sets.
[0137] In one example, if Fig.10 As shown, the apparatus 900 further includes: a sending module 920, configured to send a PDCCH to the terminal device based on the control channel resources indicated by the n control channel resource sets.
[0138] In one example, the number of repetitions n is counted in the number of repeated transmissions of the PDCCH; or, the number of repetitions n is not counted in the number of repeated transmissions of the PDCCH.
[0139] In one example, the configuration information is used to indicate the n repeated control channel resource sets.
[0140] In one example, the configuration information is used to indicate a third control channel resource set, and the third control channel resource set includes the n repeated control channel resource sets.
[0141] In summary, the technical solution provided by the embodiment of the present application configures multiple control channel resource sets in a single time slot, so that the control channel resource set occupies more time domain resources in a single time slot, so that the communication information between the network device and the terminal device can occupy more control channel resources for transmission, thereby improving the transmission performance of the control channel. Since the communication information occupies more control channel resources for transmission, it is convenient to achieve the purpose of repeated transmission of the communication information. Through repeated transmission, the impact of the number of radio frequency channels of the terminal device on the downlink coverage of the network device can be reduced, thereby achieving the purpose of enhanced coverage. Moreover, in the embodiment of the present application, the multiple control channel resource sets configured in a single time slot are repeated control channel resource sets. When configuring multiple control channel resource sets, only one control channel resource set needs to be designed, and the design of other control channel resource sets can directly follow the design of the control channel resource set, so that the design in each control channel resource set can follow the design of the control channel resource set in the related technology, which simplifies the standard design and reduces the complexity of the terminal device implementation. In addition, in the embodiments of the present application, since the design within each control channel resource set can follow the design of the control channel resource set in the related technology, not only can the terminal equipment with enhanced coverage after the communication protocol is updated use the control channel resource set indicated by the configuration information, but the terminal equipment before the communication protocol is updated can also use the control channel resource set indicated by the configuration information, thereby achieving the sharing of control channel resources by the two and improving resource reuse and utilization efficiency.
