Description

Communication method, communication device and computer readable storage medium

Technical Field

Embodiments of the present disclosure relate to the field of communications technologies, and in particular, to a communication method, a communication apparatus, and a computer-readable storage medium.

Background

In a New Radio (NR) communication system of the fifth Generation (5 th-Generation, 5G), a concept of a partial bandwidth part (BWP) is introduced. With diversified service requirements, the terminal device has different application capabilities for BWP, for example, massive machine type communications (mtc) services are mainly characterized by huge number of networking devices, small amount of data transmission, and insensitivity to transmission delay, and user devices of these mtc services often need to meet the requirements of low cost and very long standby time.

In a 5G NR communication system, there are many high concurrent services with huge numbers of networking devices, and terminal devices of such high concurrent services often communicate on the same fixed bandwidth. However, the bandwidth resources supported by the services are limited, and the bandwidth resources of some services (such as the mtc services described above) are relatively narrow, which may cause access congestion of these terminal devices if these terminal devices are accessed in the same narrow BWP.

Therefore, how to reasonably configure resources for the terminal device and improve the resource utilization rate is a technical problem which needs to be solved urgently.

Disclosure of Invention

Embodiments of the present application provide a communication method, a communication apparatus, and a computer-readable storage medium, which are used to implement flexible configuration of a bandwidth of a first initial BWP, thereby improving communication efficiency and resource utilization.

In a first aspect, an embodiment of the present application provides a communication method, and in order to improve communication efficiency and resource utilization, in the embodiment of the present application, a bandwidth of a first initial BWP in which a terminal device communicates with a network device may be flexibly configured according to a first capability of the terminal device. It should be understood that the network device in the embodiment of the present application may be a radio access network device in a 5G mobile communication system, for example, a base station in the 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system; the terminal device may be a terminal device or a User Equipment (UE) in the 5G mobile communication system, and specifically may be a reduced capability (REDCAP) UE, that is, a terminal device of an mtc service.

In this application, the first capability of the terminal device means whether the terminal device supports the bandwidth of the initial BWP of the terminal device may not include the first resource. The first capability is reported or indicated by the first information in the embodiment of the present application. For example, reporting the first information may be reporting in an implicit manner. For example, the network device defaults to the terminal device supporting the first capability. For example, the network device default terminal device does not support the first capability. For example, the terminal device does not need to send signaling carrying information about the first capability of the terminal device, and the network device defaults that the terminal device supports the first capability. For example, reporting the first information may be reporting explicitly. For example, the terminal device sends signaling carrying information about the first capability of the terminal device, and the network device can determine whether the terminal device supports the first capability.

Specifically, the terminal device may report the first information to the network device first. The first information indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource or the first information indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource. Or, in brief, it may also be understood that the first information indicates that the initial BWP of the terminal device may not include the first resource, or that the first information indicates that the initial BWP of the terminal device needs to include the first resource. Wherein the first resource includes at least one of a resource of a Synchronization Signal block (Synchronization Signal and PBCH block, SSB), a resource of a Common Search Space (CSS), a resource of a control resource set (CORESET), a resource of a channel state information reference Signal (CSI-RS), or a resource of a Tracking Reference Signal (TRS).

Specifically, the above-mentioned "may not be included", and it is to be understood that "may be included or not included". For example, the bandwidth of the BWP of the terminal device may not include the first resource, which may be understood as that the terminal device supports communication over a bandwidth that includes the BWP of the first resource, as well as supporting communication over a bandwidth that does not include the BWP of the first resource.

Whereas "need to include" may mean that the first resource is necessarily included in the bandwidth of the BWP of the terminal device, or that the terminal device is not able to operate in a BWP whose bandwidth does not include the first resource.

Specifically, the term "the bandwidth of the initial BWP of the terminal device may not include the first resource" in the embodiment of the present application means that the bandwidth of the initial BWP in which the terminal device communicates cannot receive the information carried on the first resource. The resources are frequency domain resources, bandwidth of carrier, bandwidth of BWP, time domain resources and time-frequency domain resources. The concrete can be represented as follows: the bandwidth of the initial BWP of the terminal device is completely misaligned (completely staggered) or only partially coincides with the first resource. Illustratively, taking the example that the first resource includes the bandwidth of the SSB, if the bandwidth of the initial BWP of the terminal device is completely misaligned (completely staggered) with the bandwidth of the SSB. When the terminal device is in the initial BWP operation or communication, the SSB will not be acquired by the terminal device.

However, currently, in practical applications, not all terminal devices may by default support the bandwidth of the initial BWP of the terminal device without including the first resource. This first capability may be configured by the manufacturer of the terminal device. Some vendors may exclude the first resource from the bandwidth that the end device supports the initial BWP, and some vendors may include the first resource from the bandwidth that the end device's initial BWP needs. In this embodiment, in order to adapt to different first capabilities of the terminal device, a first initial BWP for the terminal device to communicate with the network device may be flexibly configured according to the first information reported by the terminal device.

After the terminal device reports the first information to the network device, the network device may determine the first capability of the terminal device, that is, the network device may determine whether the bandwidth of the initial BWP of the terminal device may not include the first resource.

Specifically, in one aspect, if the first information indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource, the bandwidth of the first initial BWP where the terminal device communicates with the network device may not be overlapped with the first resource completely (i.e. staggered completely), or only partially overlapped. Illustratively, assuming that the frequency range of the first resource is {20MHZ-40MHZ }, the frequency range of the first initial BWP may be {45MHZ-65MHZ }, i.e., the bandwidth of the first initial BWP is completely misaligned (i.e., completely staggered) with the first resource, or the frequency range of the first initial BWP may be {30MHZ-50MHZ }, i.e., the bandwidth of the first initial BWP is only partially aligned with the first resource.

On the other hand, if the first information indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource, in this application, the bandwidth of the first initial BWP where the terminal device communicates with the network device must include the first resource. In other words, the first initial BWP may be a wider BWP covering the first resource, or the first initial BWP and the first resource may completely coincide. Illustratively, assuming that the frequency range of the first resource is 20MHz-40MHz, the frequency range of the first initial BWP may be 20MHz-50MHz, or 15MHz-40MHz, or 20MHz-40 MHz. I.e. the bandwidth of the first initial BWP comprises the first resource.

In this embodiment of the present application, a first initial BWP where the terminal device communicates with the network device is determined according to the first information reported by the terminal device, and for the terminal device supporting the capability, the network device may provide more resource allocations (the resource may not include the first resource). For the terminal device which does not support the capability, the network device provides relatively crowded resources (the resources include the first resource), and the configuration of the first initial BWP for the network device provides greater flexibility, thereby improving the communication efficiency and the resource utilization rate.

Based on the first aspect, in an optional implementation manner, for a case that the first capabilities of the terminal device are inconsistent, in order to adapt to different first capabilities of the terminal device, the first initial BWP for the terminal device to communicate with the network device is flexibly configured according to an indication of the first information reported by the terminal device.

When the first information reported by the terminal device to the network device indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource, the network device may configure an independent initial BWP for the terminal device. Or the first information indicates that the initial BWP of the terminal device may not include the first resource, the network device may configure a separate initial BWP for the terminal device. The independent initial BWP may be the first initial BWP for the terminal device. The bandwidth dedicated to such an initial BWP allowing the terminal device may be used by the terminal device without including the first resource, and a separate initial BWP (first initial BWP) is used for the terminal device to communicate with the network device. The network device may provide the network device with configuration flexibility to configure the independent initial BWP for the terminal device, i.e. allow the network device to configure the independent initial BWP for the terminal device, and also allow the network device not to configure the independent initial BWP for the terminal device.

When the first information reported by the terminal device to the network device indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource, the network device does not configure the first initial BWP of the terminal device as an independent initial BWP. In other words, the terminal device does not expect (disallow) the first initial BWP to be configured as an independent initial BWP. If the first initial BWP of the terminal device is configured as the independent initial BWP, the terminal device may consider this to be a configuration error or a signaling error, or may not switch to the independent initial BWP or may not communicate at the independent initial BWP.

In this embodiment, the network device determines, for the condition of the first information reported by the terminal device, whether a first initial BWP in which the terminal device communicates with the network device is an independent initial BWP. For a terminal device operating in an independent initial BWP (i.e. the first initial BWP is the independent initial BWP), the dedicated BWP communicates with the network device, so as to alleviate resource congestion and achieve the purpose of load balancing; for the terminal devices that are not operating on the independent initial BWP (i.e., the first initial BWP is not the independent initial BWP), when some terminal devices switch to communicate on the independent initial BWP, the number of terminal devices accessing the bandwidth on which the remaining terminal devices (i.e., the terminal devices that are not switching to communicate on the independent initial BWP) operate is also reduced to some extent, thereby also improving communication efficiency and resource utilization.

When the first information reported by the terminal device to the network device indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource, the network device may configure the independent initial BWP for the terminal device. Or the first information indicates that the initial BWP of the terminal device may not include the first resource, the network device may configure the independent initial BWP for the terminal device. The independent initial BWP may be the first initial BWP for the terminal device. The bandwidth dedicated to such an initial BWP for the end device may be used by the end device without including the first resource, and a separate initial BWP (first initial BWP) is used for the end device to communicate with the network device. The network device may provide the network device with configuration flexibility to configure the independent initial BWP for the terminal device, i.e. allow the network device to configure the independent initial BWP for the terminal device, and also allow the network device not to configure the independent initial BWP for the terminal device. In this embodiment, for a terminal device supporting the first capability, the terminal device may be configured on a dedicated BWP to communicate with a network device, so as to alleviate the situation of network congestion and achieve the purpose of load balancing.

When the first information reported by the terminal device to the network device indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource, and the independent initial BWP includes the first resource, in this case, the network device may configure the independent initial BWP for the terminal device. Or the first information indicates that the initial BWP of the terminal device may not include the first resource, the network device may configure a separate initial BWP for the terminal device. The independent initial BWP may be the first initial BWP for the terminal device. In this case, the first initial BWP (independent initial BWP) may be a wider BWP covering the first resource, so that the terminal devices can communicate with the network device over the wider independent initial BWP, and avoid too many terminal devices communicating on the same narrow bandwidth, thereby alleviating the network congestion.

When the first information reported by the terminal device to the network device indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource and the independent initial BWP does not include the first resource, in this case, the network device will not configure the terminal device to configure the first initial BWP as the independent initial BWP. In other words, the terminal device does not expect (disallow) the first initial BWP to be configured as an independent initial BWP.

In the embodiment of the application, the terminal device reports the first information to the network device. The first information indicates that the bandwidth of the BWP of the terminal device may not include the first resource or that the bandwidth of the BWP of the terminal device needs to include the first resource.

Based on the first aspect, in an optional implementation manner, the terminal device reports second information to the network device, where the second information is used to indicate a maximum number of tuning times supported by the terminal device in the first time period. The first time period includes M1 time units. The time unit may be at least one of a slot, a subframe, a frame, a DRX (Discontinuous Reception) cycle, a system information update cycle, a paging cycle, a radio resource check (RRM) measurement cycle, or a measurement cycle. M1 is a positive integer. The number of times of tuning is the number of times of frequency tuning. Where tuning may be understood as the need for the terminal device to switch out of the first initial BWP due to measurements or frequency hopping transmissions, etc. Such as BWP being active BWP or initial BWP.

In practical applications, since the terminal device communicates on the second BWP that does not include the first resource, the information on the corresponding first resource cannot be acquired by the terminal device, but for example, for the case that the first resource is an SSB, the SSB does not need to be acquired by the terminal device in real time, the SSB of the network device is sent cyclically within a certain period, and the terminal device may switch to the first resource to communicate when the SSB needs to be acquired, thereby acquiring the SSB, and then switch back to the second BWP. Such as the second BWP being the active BWP or the initial BWP. Further, in order to avoid the terminal device switching BWP frequently, the tuning frequency is defined in this application, that is, the maximum tuning number of the terminal device in the first time period is defined as N. Where N may be the initial default data of the manufacturer of the terminal device. For example, N =1. Alternatively, N may be configured to the terminal device by the network device through the x 1-th signaling. For example, the x1 signaling is system information, system information block 1, RRC signaling, or MAC CE signaling. For example, the network device configures the number of times of tuning of the terminal device in the first time period to be N =2 or N =3, and so on. The value size of N is related to whether the bandwidth of the initial BWP of the terminal device may not include the first resource. For example, the network device configures the number of tunings within the first time period according to whether the bandwidth of the BWP of the terminal device may not include the first resource. For example, the network device configures the number of RRM measurements made within the DRX cycle according to whether the bandwidth of the BWP of the terminal device may not include the first resource. Since the first BWP, which is used by the terminal device to communicate with the network device, does not include the first resource, it is inevitable that the BWP needs to be switched to acquire the first resource (e.g., SSB message). For example, for a terminal device whose bandwidth of BWP may not include the first resource, the value of N configured for the terminal device may be greater than the value of N of the terminal device whose bandwidth of BWP needs to include the first resource. E.g. for a terminal device where the bandwidth of BWP needs to include the first resource, N is equal to N1. For example, for a terminal device whose bandwidth of BWP may not include the first resource, N is equal to N2. For example, N1 is less than or equal to N2. E.g., N1=1. E.g., N1=2. For example, N2 is greater than 1. E.g., N2=2. E.g., N2=3. E.g., N2=4.

In this embodiment, the maximum number of times of tuning supported by the terminal device in the first time period is indicated by reporting the second information, that is, the number of times of tuning that the first terminal device does not expect to occur in the first time period exceeds the maximum number of times of tuning supported by the first terminal device. Therefore, the frequency of switching the BWP by the terminal device is limited, and the terminal device is prevented from switching the BWP or tuning the frequency too frequently, so that the energy consumption of the terminal device is saved. Meanwhile, the limitation of the tuning times of the terminal equipment is determined according to the capability of the terminal equipment, and the flexibility of scheduling and configuration is increased for the base station.

In this embodiment, the terminal device may further report third information to the network device, where the third information is used to indicate whether the terminal device supports performing first measurement through the non-cell-defined NCD SSB, where the first measurement includes at least one of Radio Resource Management (RRM) measurement, radio Link Management (RLM) measurement, signal to interference and noise ratio (SINR) measurement, mobility measurement, beam Failure Recovery (BFR) measurement, or Beam Management (Beam Management, BM) measurement.

In this embodiment, the terminal device reports fourth information to the network device, where the fourth information is used to indicate whether the terminal device supports the third BWP. E.g. the third BWP is the active BWP or the initial BWP. E.g. the third BWP is an independent initial BWP. For example, the fourth information is used to indicate whether the terminal device supports being configured with the third BWP. E.g. meaning that the terminal device may be configured with BWP where the bandwidth does not include the first resource, or meaning that the terminal device does not include the first resource within the bandwidth supporting BWP, or meaning that the terminal device supports the first measurement by NCD SSB. For example, the terminal device reports that the third BWP is not configured, which means that the terminal device cannot be configured with BWP whose bandwidth does not include SSB, or means that the terminal device does not include the first resource in the bandwidth that does not support BWP, or means that the terminal device does not support the first measurement by NCD SSB. And reporting the fourth information to assist the terminal device in reducing the complexity, wherein if the terminal device wants to reduce the complexity or considers that the complexity caused by the handover is high, the terminal device may report that the third BWP is not supported. If the terminal device considers that the complexity caused by the handover is not high or wants to acquire the possibility of communicating with the network device in a larger bandwidth range, the terminal device may report that the third BWP is supported.

On the other hand, if the second time period configured by the network device is less than or equal to the second threshold, the terminal device does not expect that the first bandwidth does not include the first resource. For example, the first bandwidth does not include the first resource, and the configuration of the second time period should be greater than or equal to the second threshold. E.g., (the bandwidth of) the initial BWP, (the bandwidth of) the independent initial BWP, (the bandwidth of) the RRC-configured BWP or (the bandwidth of) the terminal device-specific BWP. For example, the terminal device may be a terminal device that does not include the first resource for the bandwidth that does not support BWP, or a low complexity terminal device. For example, the second time period may be M3 time units. M3 is a positive integer.

E.g., the second time period is network indicated or predefined. For example, the second time period may be associated with the first measurement, or the second time period may be greater than the time required for the first measurement, or the first measurement may be taken during the second time period. For example, the second threshold value is a predefined value. For example, the second threshold is 10ms, 20ms, 10 slots, 64 slots, 1 frame, 1 radio frame, or 1 measurement period. For example, the terminal device supports the first bandwidth without including the first resource, and the second threshold is 1 frame. For example, the terminal device does not support the first bandwidth without including the first resource, and the second threshold is 2 frames.

For example, the second threshold value is determined based on the terminal device capabilities. And if so, the terminal equipment reports the value of the second threshold. For example, the terminal device reports the minimum time interval between two supported tunings, i.e. the second threshold. And if the first bandwidth reported by the terminal equipment does not comprise the first resource, the minimum second time period is supported.

As shown in fig. 1, the network device is configured with the second time period being less than or equal to the second threshold value, and the first bandwidth includes the first resource. That is, the configuration of the network device is limited, and the first bandwidth must include the first resource. As shown in fig. 2, the network device is configured with the second time period being greater than or equal to the second threshold value, and the first bandwidth may not include the first resource. That is, the network device may determine that the first bandwidth must include the first resource based on whether the network resource is congested. As in fig. 3, the first bandwidth includes the first resource, and the second time period may be less than or equal to a second threshold value. As shown in fig. 3, the first bandwidth does not include the first resource, and the terminal device does not expect the second time period to be less than or equal to the second threshold, or the second time period to be greater than or equal to the second threshold.

For example, the DRX cycle configured by the network device for the terminal device is less than or equal to the second threshold, and the network device cannot configure BWP with a bandwidth that does not include SSB for the terminal device. Or, the network device configures the BWP whose bandwidth does not include the SSB for the terminal device, and the DRX cycle configured by the network device for the terminal device should be greater than or equal to the second threshold. For example, RRM measurements performed in a DRX cycle require SSBs to be detected, tuning is required if the bandwidth of the BWP does not include SSBs, and the terminal device may not be as long as performing RRM measurements in a cycle if the DRX cycle is short. Thus, restricting intra-BWP DRX to bandwidths that do not include SSBs requires configuring a cycle long enough to ensure that RRM measurements are complete.

In this application, the first information, the second information, the third information, and the fourth information may be sent independently or in combination, and when a plurality of pieces of information are sent, the first information, the second information, the third information, and the fourth information may be carried in the same message or different messages, which is not limited in this embodiment of the application.

In a possible implementation, the second information, the third information, or the fourth information may be reported independently without depending on the reporting of the first information, for example, the terminal device may report only the second information without reporting the first information, and the second information may indicate the maximum tuning number supported by the terminal device in the first time period, so as to implement flexible configuration of the network device.

Based on the first aspect, in an optional implementation manner, the second information, the third information, or the fourth information may be an indication of the terminal device in a Radio Resource Control (RRC) connected state. For example, the second information is used to indicate a maximum number of tuning times that the terminal device supports in the RRC connected state during the first time period; the third information is used for indicating whether the terminal equipment supports the first measurement through the non-cell-defined NCD SSB in the RRC connection state; the fourth information is for indicating whether the terminal device supports independent initial BWP in the RRC connected state. For detailed descriptions of the second information, the third information, and the fourth information, please refer to the above description specifically, and details are not repeated here.

Based on the first aspect, in an optional implementation manner, when the terminal device is in an idle state or an inactive state, in order to obtain connection with the network device, the terminal device and the network device need to obtain uplink synchronization and downlink synchronization. When the terminal device decodes the SSB, it has already acquired downlink synchronization, and the terminal device needs to initiate Random Access Channel (RACH) to the network device in order to establish uplink and downlink synchronization and Radio Resource Control (RRC) connection. In practical applications, the Random Access manner of the terminal device can be divided into a Random Access procedure Based on Contention (CBRA) and a Random Access procedure Based on Non-Contention-Based or Contention-Free Access (CFRA). The communication method provided by the present application is applicable to the random access procedure in any manner, and is not limited herein.

In the embodiment of the present application, in the random access process, the network device may first transmit the configuration information of the configured initial BWP to the terminal device through a system message or SSB. After acquiring the information, the terminal device determines the first initial BWP for random access according to whether the bandwidth of the initial BWP of the terminal device may not include the first resource. Illustratively, the network device may send configuration information of two initial BWPs to the terminal device through a system message or SSB, where a bandwidth of one initial BWP includes the first resource (BWP 1) and a bandwidth of the other initial BWP does not include the first resource (BWP 2). E.g. one initial BWP is an independent initial BWP and one initial BWP is a non-independent initial BWP. After receiving the configuration information of the two initial BWPs, the terminal device selects one of the initial BWPs for random access according to its first capability, that is, according to whether the bandwidth of the initial BWP of the terminal device may not include the first resource. If the bandwidth of the initial BWP of the terminal device may not include the first resource, the terminal device initiates a random access procedure with BWP2 (the bandwidth of which is the initial BWP that does not include the first resource) as the first initial BWP. The terminal device initiates a random access procedure from BWP2 (independent initial BWP), which is equivalent to reporting the first information on BWP2, or equivalent to reporting the first information on a random access resource of BWP 2. Wherein the first information indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource. If the bandwidth of the initial BWP of the terminal device needs to include the first resource, the terminal device initiates a random access procedure with BWP1 (whose bandwidth is the initial BWP including the first resource) as the first initial BWP. The terminal device initiates a random access procedure from BWP1 (dependent initial BWP), which is equivalent to reporting the first information on BWP1, or equivalent to reporting the first information on a random access resource of BWP 1. Wherein the first information indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource.

And when the terminal equipment is in an idle state or an inactive state, the first information can be carried in the random access message for reporting. Specifically, the first message may be carried in at least one of Msg1, msg3, msgA, or Msg5 in the random access process to complete reporting. In this embodiment, the terminal device reports the first information during the random access process, so as to directly determine the first initial BWP that needs to communicate with the network device in the random access stage, thereby improving the communication efficiency.

In an alternative embodiment based on the first aspect, the first initial BWP is determined based on the first information; or

The first information is indicated according to signaling from the network device.

In a second aspect, the present embodiment provides a communication method, in which a network device determines first information of a terminal device, the first information indicating that a bandwidth of an initial partial bandwidth BWP of the terminal device may not include a first resource or that the bandwidth of the initial BWP of the terminal device needs to include the first resource, wherein the first resource includes at least one of a resource of a synchronization signal block SSB, a resource of a common search space, a resource of a control resource set, a resource of a channel state information reference signal, or a resource of a tracking reference signal;

Detailed Description

Embodiments of the present application provide a communication method, a communication apparatus, and a computer-readable storage medium, which implement flexible configuration of a bandwidth of a first initial BWP, thereby improving communication efficiency and resource utilization.

The embodiments of the present application will be described below with reference to the drawings. The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application. As can be known to those skilled in the art, with the development of technology and the emergence of new scenarios, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be implemented in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

For ease of understanding, a description will first be made of several basic concepts involved in the embodiments of the present application.

1. Synchronization signal block SSB: the system is composed of a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH), and occupies 4 symbols in a time domain and 240 subcarriers in a frequency domain. Within the frequency range of one carrier, multiple SSBs may be transmitted. The terminal device may obtain physical layer cell Identity (ID) and timeslot synchronization through PSS, obtain Cyclic Prefix (CP) length, physical cell group ID, and frame synchronization through SSS, and obtain a Master Information Block (MIB) including common antenna port number, system Frame Number (SFN), downlink system bandwidth, and physical hybrid automatic repeat indicator (PHICH) configuration information by decoding PBCH.

2. Control resource set CORESET: and carrying resources of the downlink control information. The downlink control information may be used to carry scheduling information for uplink transmission or downlink transmission. The downlink control information carried by CORESET #0 may be used to carry scheduling information of system information block 1 (system information block 1, sib1).

3. Common search space CSS: can be used for carrying common downlink control information or terminal equipment specific downlink control information. The method mainly comprises the following types:

type0-PDCCH CSS set, which is a search space set for transmission of control information of system information block 1 (SIB 1). Transmitting control information (DCI) in which a Cyclic Redundancy Check (CRC) is scrambled by a system information radio network temporary identifier (SI-RNTI) in the search space set;

type0A-PDCCH CSS set, which is a search space set for transmitting control information of other system information (except SIB 1). Transmitting DCI with CRC scrambled by SI-RNTI in the search space set;

type1-PDCCH CSS set, which is a search space set used for transmitting control information in the random access process;

type2-PDCCH cssset, which is a search space set for transmitting control information for cyclic information or system information update.

4. Partial bandwidth BWP: in the 5G NR system, the concept of BWP is introduced. The introduction of BWP, which can realize the cost and power consumption of the control terminal device, is a key technology in 5G. Between the performance, cost and flexibility of the terminal device, the flexible configuration and processing can be performed by switching the BWP mode, so that the 5G NR system is very flexible in configuring the bandwidth. For easy understanding, please refer to fig. 1, in which fig. 1 is a schematic diagram of a scenario in which a terminal device switches BWP. In the time axis shown in fig. 1, if the traffic of the terminal device at the first time is large, the access network device (gNB) in the 5G NR system may configure a large bandwidth (i.e. BWP1 in fig. 1) for the terminal device; at the second moment, the traffic of the terminal device is smaller, and the gNB may configure a small bandwidth (i.e., BWP2 in fig. 1) for the terminal device, so as to meet the basic communication requirement; at the third time, gNB finds that there is wide-range frequency selective fading in the bandwidth of BWP1, or that there is a shortage of resources in the frequency range of BWP1, and then gNB may configure a new bandwidth (i.e. BWP3 in fig. 1) for the terminal device. Therefore, the spectrum resources can be used as required, the terminal equipment does not need to work on the whole carrier bandwidth, and the method is more flexible and more power-saving.

It should be understood that the basic concepts of the synchronization signal block SSB, the common search space CSS, the control resource set (CORESET), and the BWP described above have been defined in detail in the existing protocol, and the description of the SSB, the CSS, the control resource set (CORESET), and the BWP is not intended to limit the scope of protection of the present application, but to enhance the understanding of the embodiments of the present application.

Next, application scenarios related to embodiments of the present application will be described.

5. Mobile communication technology has profoundly changed people's lives, but the pursuit of higher performance mobile communication technology has never stopped. In order to cope with explosive mobile data traffic growth, device connection of mass mobile communication, and various new services and application scenarios that are continuously emerging, a fifth Generation (5 th-Generation, 5G) new air interface communication system is being developed. The International Telecommunications Union (ITU) defines three broad classes of application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), high-reliability and low-latency communications (URLLC), and massive machine type communications (mtc).

Typical eMBB services are: ultra-high definition video, augmented Reality (AR), virtual Reality (VR), and the like, and these eMBB services are mainly characterized by large transmission data volume and high transmission rate; typical URLLC services are: the wireless control in the industrial manufacturing or production flow, the motion control of the unmanned automobile and the unmanned airplane, the remote repair, the remote operation and other touch interactive applications, and the URLLC business is mainly characterized by requiring ultrahigh reliability, low time delay, less transmission data volume and having burstiness; typical mtc services are: the intelligent power distribution automation, the smart city and the like are mainly characterized in that the number of networking devices is large, the transmission data volume is small, data is insensitive to transmission delay, and the terminal devices of the mMTC service generally need to meet the requirements of low cost and very long standby time.

In the 5G NR communication system, there are many high-concurrency services with huge numbers of networking devices, and terminal devices of such high-concurrency services often communicate on the same fixed bandwidth. However, the bandwidth resources supported by the services are limited, and the bandwidth resources of some services (such as the mtc services described above) are relatively narrow, which may cause access congestion of these terminal devices if these terminal devices are accessed in the same narrow BWP.

In view of the above, embodiments of the present application provide a communication method, a communication apparatus, and a computer-readable storage medium for implementing flexible configuration of a bandwidth of a first initial BWP, thereby improving communication efficiency and resource utilization.

To facilitate understanding of the embodiments of the present application, first, a mobile communication system applied to the embodiments of the present application will be described in detail by taking the mobile communication system shown in fig. 2 as an example. Referring to fig. 2, fig. 2 is a schematic diagram of a mobile communication system according to an embodiment of the present disclosure. As shown in fig. 2, the mobile communication system includes a core network device 210, a radio access network device 220, and at least one terminal device (e.g., a terminal device 230 and a terminal device 240 in fig. 2). The terminal equipment is connected with the wireless access network equipment in a wireless mode, and the wireless access network equipment is connected with the core network equipment in a wireless or wired mode. The core network device and the radio access network device may be separate physical devices, or the function of the core network device and the logical function of the radio access network device may be integrated on the same physical device, or a physical device may be integrated with a part of the function of the core network device and a part of the function of the radio access network device. The terminal equipment may be fixed or mobile. Fig. 2 is a schematic diagram, and other network devices, such as a wireless relay device and a wireless backhaul device, may also be included in the communication system, which are not shown in fig. 2. The embodiments of the present application do not limit the number of core network devices, radio access network devices, and terminal devices included in the mobile communication system.

It should be understood that the network device in the communication method provided by the embodiment of the present application may be the radio access network device 220 in fig. 2, for example, a base station in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; the terminal device may be the terminal device 230 or the terminal device 240 in fig. 2, and specifically may be REDCAP UE (reduced capability), that is, a terminal device of mtc service.

Specifically, the terminal device in the present application may be a first type terminal device or a second type terminal device, and the first type terminal device and the second type terminal device may have at least one of the following distinguishing features:

1. the bandwidth capabilities are different, e.g. the maximum bandwidth supported by the first type of terminal device is smaller than the maximum bandwidth supported by the second type of terminal device.

2. The number of transceiving antennas is different, for example, the number of transceiving antennas supported by the first type terminal device is smaller than the number of transceiving antennas supported by the second type terminal device.

3. The uplink maximum transmission power is different, for example, the uplink maximum transmission power supported by the first type terminal device is smaller than the uplink maximum transmission power supported by the second type terminal device.

4. The protocol versions are different. For example, the first type of terminal device may be a terminal device in NR version 17 (release-17, rel-17) or in later versions of NR Rel-17. The second type of terminal device may be, for example, a terminal device in NR version 15 (release-15, rel-15) or NR version 16 (release-16, rel-16). The second type of terminal equipment may also be referred to as NR legacy (NR legacy) terminal equipment.

5. The processing power for the data is different. For example, the minimum time delay between the reception of the downlink data and the transmission of the feedback to the downlink data by the first type terminal device is greater than the minimum time delay between the reception of the downlink data and the transmission of the feedback to the downlink data by the second type terminal device; and/or the minimum time delay between the first type terminal equipment sending the uplink data and receiving the feedback of the uplink data is larger than the minimum time delay between the second type terminal equipment sending the uplink data and receiving the feedback of the uplink data.

6. The supported Carrier Aggregation (CA) capabilities are different, e.g., the second type terminal device may support carrier aggregation, while the first type terminal device does not support carrier aggregation; for another example, the second type terminal device and the first type terminal device both support carrier aggregation, but the maximum number of carrier aggregation supported by the second type terminal device is greater than the maximum number of carrier aggregation supported by the first type terminal device, for example, the second type terminal device may support aggregation of at most 5 carriers or 32 carriers, while the first type terminal device supports aggregation of at most 2 carriers simultaneously.

7. The communication modes are different, for example, the second type terminal device supports full duplex Frequency Division Duplex (FDD), while the first type terminal device supports only half duplex FDD.

8. The processing capacity is different, and the processing capacity of the first type terminal equipment is smaller than that of the second type terminal equipment.

The second type of terminal device has, but is not limited to, the above distinguishing features with the first type of terminal device.

In a possible implementation manner, the first type terminal device may refer to a REDCAP terminal device, or the first type terminal device may also refer to a low-capability terminal device, a Reduced-capability terminal device, a REDCAP UE, a Reduced-Capacity UE, a narrowband-band NR (NB-NR) UE, and the like. The second type of terminal device may refer to a legacy capability or a normal capability or a high capability terminal device, and may also be referred to as a legacy (legacy) terminal device or a normal (normal) terminal device.

In this embodiment, the first initial BWP may be at least one of an initial BWP, an initial upstream BWP, an initial downstream BWP, an upstream BWP, or a downstream BWP. For example, taking the first initial BWP as the first initial downlink BWP, the network device additionally configures a separate initial downlink BWP for the first type terminal device, which is referred to as the first initial downlink BWP.

The first initial downlink BWP may support configuring a paging message (paging) Search Space (SS), a Random Access (RA) SS, an SIB1 SS, and Other System Information (OSI) SS, or may support not configuring at least one of the paging SS, the RA SS, the SIB1 SS, and the OSI SS; that is, for any of the above SSs, the network device may or may not configure the SS in the first initial downlink BWP.

The radio access network device is an access device in which the terminal device is wirelessly accessed to the mobile communication system, and may be a base station NodeB, an evolved node b, a base station in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, and the like.

The wireless access network equipment and the terminal equipment can be deployed on land, including indoors or outdoors, and are handheld or vehicle-mounted; can also be deployed on the water surface; it may also be deployed on aerial airplanes, balloons, and satellites. The embodiment of the application does not limit the application scenarios of the wireless access network device and the terminal device.

The embodiment of the application can be suitable for downlink signal transmission, can also be suitable for uplink signal transmission, and can also be suitable for device to device (D2D) signal transmission. For downlink signal transmission, the sending device is a radio access network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the transmitting device is a terminal device, and the corresponding receiving device is a radio access network device. For D2D signaling, the sending device is a terminal device, and the corresponding receiving device is also a terminal device. The embodiment of the present application does not limit the transmission direction of the signal.

The radio access network device and the terminal device, and the terminal device may communicate via a licensed spectrum (licensed spectrum), may communicate via an unlicensed spectrum (unlicensed spectrum), and may communicate via both the licensed spectrum and the unlicensed spectrum. The radio access network device and the terminal device may communicate with each other through a spectrum of 6G or less, may communicate through a spectrum of 6G or more, and may communicate using both a spectrum of 6G or less and a spectrum of 6G or more. The embodiments of the present application do not limit the spectrum resources used between the radio access network device and the terminal device.

Next, a communication method in the embodiment of the present application will be described. Referring to fig. 3, fig. 3 is a schematic flowchart of a communication method in an embodiment of the present application, and as shown in fig. 3, the communication method in the embodiment of the present application includes:

301. the terminal device reports the first information to the network device, and correspondingly, the network device determines the first information of the terminal device.

In order to improve communication efficiency and resource utilization, in the embodiment of the present application, a bandwidth of a first initial BWP where the terminal device communicates with the network device may be flexibly configured according to a first capability of the terminal device.

In this application, the first capability of the terminal device means whether the terminal device supports the bandwidth of the initial BWP of the terminal device may not include the first resource. The first capability is reported or indicated by the first information in the embodiment of the present application. For example, reporting the first information may be reporting in an implicit manner. For example, the network device defaults to the terminal device supporting the first capability. For example, the network device default terminal device does not support the first capability. For example, the terminal device does not need to send signaling carrying information about the first capability of the terminal device, and the network device defaults that the terminal device supports the first capability. For example, reporting the first information may be explicitly reporting. For example, the terminal device sends signaling carrying information about the first capability of the terminal device, and the network device can determine whether the terminal device supports the first capability.

302. The terminal device communicates with the network device at the first initial BWP, and accordingly, the network device determines to communicate with the terminal device at the first initial BWP according to the first information.

Specifically, on one hand, if the first information indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource, in this application, the bandwidth of the first initial BWP where the terminal device communicates with the network device may not overlap the first resource at all (i.e., may be staggered at all), or may only partially overlap the first resource. Illustratively, assuming that the frequency range of the first resource is {20MHZ-40MHZ }, the frequency range of the first initial BWP may be {45MHZ-65MHZ }, i.e., the bandwidth of the first initial BWP is completely misaligned (i.e., completely staggered) with the first resource, or the frequency range of the first initial BWP may be {30MHZ-50MHZ }, i.e., the bandwidth of the first initial BWP is only partially overlapped with the first resource.

On the other hand, if the first information indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource, in this application, the bandwidth of the first initial BWP where the terminal device communicates with the network device must include the first resource. In other words, the first initial BWP may be a wider BWP covering the first resource, or the first initial BWP and the first resource may completely coincide. Illustratively, assuming that the frequency range of the first resource is 20MHz-40MHz, the frequency range of the first initial BWP may be 20MHz-50MHz, or 15MHz-40MHz, or 20MHz-40 MHz. I.e., the bandwidth of the first initial BWP includes the first resource.

Optionally, on the basis of the embodiment corresponding to fig. 3, in an optional embodiment of the communication method provided in the embodiment of the present application, for a case that the first capabilities of the terminal device are inconsistent, in order to adapt to different first capabilities of the terminal device, the first initial BWP for the terminal device to communicate with the network device is flexibly configured according to an indication of the first information reported by the terminal device.

For easy understanding, please refer to fig. 4, wherein fig. 4 is a schematic diagram illustrating a scenario of configuring the first initial BWP according to the indication of the first information in the embodiment of the present application. As shown in fig. 4, in an aspect, when the first information reported by the terminal device to the network device indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource, the network device may configure an independent initial BWP for the terminal device. Or the first information indicates that the initial BWP of the terminal device may not include the first resource, the network device may configure the independent initial BWP for the terminal device. The independent initial BWP may be the first initial BWP for the terminal device. The bandwidth dedicated to such an initial BWP allowing the terminal device may be used by the terminal device without including the first resource, and a separate initial BWP (first initial BWP) is used for the terminal device to communicate with the network device. The network device may provide the network device with configuration flexibility to configure the independent initial BWP for the terminal device, i.e. allow the network device to configure the independent initial BWP for the terminal device, and also allow the network device not to configure the independent initial BWP for the terminal device.

As shown in fig. 4, on the other hand, when the first information reported by the terminal device to the network device indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource, the network device does not configure the first initial BWP of the terminal device as an independent initial BWP. In other words, the terminal device does not expect (disallow) the first initial BWP to be configured as an independent initial BWP. If the terminal device first initial BWP is configured as the standalone initial BWP, the terminal device may consider this to be a configuration error or a signaling error or may not switch to the standalone initial BWP or may not communicate at the standalone initial BWP.

For example, the independent initial BWP (separate initial BWP) is a specific (or proprietary) BWP for the first end device, or a BWP configured for the network device only for the first end device. For example, the independent initial BWP includes an independent initial upstream BWP and an independent initial downstream BWP. For example, the independent initial BWP is a BWP that is not shared with the second terminal device. The first terminal device and the second terminal device are different types of terminal devices. For example, the first terminal device is a low complexity UE, and the second terminal device is a legacy UE. For example, the first terminal device is an R17 low complexity UE, and the second terminal device is an R18 low complexity UE. For example, the first terminal device is a UE supporting the maximum number of antennas (or the number of radio frequency channels) is 1, and the second terminal device is a UE supporting the maximum number of antennas (or the number of radio frequency channels) is 2.

For example, the independent initial BWP is a different BWP than previously configured. E.g. a non-standalone initial BWP is a BWP shared with other (type) terminal devices. For example, the dependent initial BWP configures the BWP for the MIB. For example, the independent initial BWP is an SIB configured BWP or an RRC configured BWP or a BWP not configured for MIB. E.g., the non-independent initial BWP is the BWP configured or used in the initial access procedure. E.g. the independent initial BWP is the BWP configured or used after the initial access procedure. For example, the dependent BWP is CORESET #0 (resource).

In this embodiment, the network device determines, for a condition of the first information reported by the terminal device, whether a first initial BWP in which the terminal device and the network device communicate with each other is an independent initial BWP. For a terminal device operating in the independent initial BWP (i.e. the first initial BWP is the independent initial BWP), the dedicated BWP communicates with the network device, so as to alleviate the resource congestion and achieve the purpose of load balancing. For a terminal device not operating in the independent initial BWP (i.e. the first initial BWP is not the independent initial BWP), when some terminal devices switch to the independent initial BWP for communication, the number of terminal devices accessing the bandwidth in which the remaining terminal devices (i.e. the terminal devices not switching to the independent initial BWP for communication) operate is also reduced to some extent, thereby improving the communication efficiency and resource utilization.

For easy understanding, please refer to fig. 5, wherein fig. 5 is a schematic diagram illustrating another scenario of configuring the first initial BWP according to the indication of the first information in the embodiment of the present application. As shown in fig. 5, in an aspect, when the first information reported by the terminal device to the network device indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource, the network device may configure an independent initial BWP for the terminal device. Or the first information indicates that the initial BWP of the terminal device may not include the first resource, the network device may configure the independent initial BWP for the terminal device. The independent initial BWP may be the first initial BWP for the terminal device. The bandwidth dedicated to such an initial BWP for the end device may be used by the end device without including the first resource, and a separate initial BWP (first initial BWP) is used for the end device to communicate with the network device. The network device may provide the network device with configuration flexibility to configure the independent initial BWP for the terminal device, i.e. allow the network device to configure the independent initial BWP for the terminal device, and also allow the network device not to configure the independent initial BWP for the terminal device. In this embodiment, for a terminal device supporting the first capability, the terminal device may be configured on a dedicated BWP to communicate with a network device, so as to alleviate the situation of network congestion and achieve the purpose of load balancing.

As shown in fig. 5, on the other hand, when the first information reported by the terminal device to the network device indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource, and the independent initial BWP includes the first resource, the network device may configure the independent initial BWP for the terminal device. Or the first information indicates that the initial BWP of the terminal device may not include the first resource, the network device may configure the independent initial BWP for the terminal device. The independent initial BWP may be the first initial BWP for the terminal device. The first initial BWP (independent initial BWP) may now be a wider BWP covering the first resource. Therefore, the terminal devices can communicate with the network device on a wider independent initial BWP, and excessive terminal devices are prevented from communicating on the same narrow bandwidth, so that the condition of resource congestion is relieved.

As shown in fig. 5, on the other hand, when the first information reported by the terminal device to the network device indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource and the independent initial BWP does not include the first resource, the network device will not configure the terminal device to configure the first initial BWP as the independent initial BWP. In other words, the terminal device does not expect (disallow) the first initial BWP to be configured as an independent initial BWP.

In the embodiment of the application, the terminal device reports second information to the network device, where the second information is used to indicate the maximum tuning times supported by the terminal device in the first time period. The first time period includes M1 time units. The time unit may be at least one of a slot, a subframe, a frame, a DRX (Discontinuous Reception) cycle, a system information update cycle, a paging cycle, an RRM measurement cycle, or a measurement cycle. M1 is a positive integer. The number of times of tuning is the number of times of frequency tuning. Where tuning may be understood as the terminal device needing to switch out of the first initial BWP due to measurements or frequency hopping transmissions, etc. Such as BWP being active BWP or initial BWP.

In practical applications, since the terminal device communicates on the second BWP that does not include the first resource, the information on the corresponding first resource cannot be acquired by the terminal device, but for example, for the case that the first resource is an SSB, the SSB does not need to be acquired by the terminal device in real time, the SSB of the network device is sent cyclically within a certain period, and the terminal device may switch to the first resource to communicate when the SSB needs to be acquired, thereby acquiring the SSB, and then switch back to the second BWP. E.g., the second BWP is the active BWP or the initial BWP. Further, in order to avoid the terminal device switching BWP frequently, the tuning frequency is defined in this application, that is, the maximum tuning number of the terminal device in the first time period is defined as N. Where N may be the initial default data of the manufacturer of the terminal device. For example, N =1. Alternatively, N may be configured to the terminal device by the network device through the x 1-th signaling. For example, the x1 signaling is system information, system information block 1, RRC signaling, or MAC CE signaling. For example, the network device configures the number of times of tuning of the terminal device in the first time period to be N =2 or N =3, and so on. The value size of N is related to whether the bandwidth of the initial BWP of the terminal device may not include the first resource. For example, the network device configures the number of tunings within the first time period according to whether the bandwidth of the BWP of the terminal device may not include the first resource. For example, the network device configures the number of RRM measurements made in the DRX cycle according to whether the bandwidth of the BWP of the terminal device may not include the first resource. Since the first BWP, which is used by the terminal device to communicate with the network device, does not include the first resource, it is inevitable that the BWP needs to be switched to acquire the first resource (e.g., SSB message). For example, for a terminal device whose bandwidth of BWP may not include the first resource, the value of N configured for the terminal device may be greater than the value of N of the terminal device whose bandwidth of BWP needs to include the first resource. E.g. for a terminal device where the bandwidth of BWP needs to include the first resource, N is equal to N1. For example, for a terminal device whose bandwidth of BWP may not include the first resource, N equals N2. For example, N1 is less than or equal to N2. E.g., N1=1. E.g., N1=2. E.g., N2 is greater than 1. E.g., N2=2. E.g., N2=3. E.g., N2=4.

For another example, the terminal device reports second information to the network device, where the second information indicates that the maximum number of times of tuning supported by the terminal device in the first time period is, and the second information also indicates that the bandwidth of the BWP of the terminal device may not include the first resource or that the bandwidth of the BWP of the terminal device needs to include the first resource. For example, the maximum tuning number reported by the terminal device is N3, which indicates that the bandwidth of the BWP of the terminal device needs to include the first resource. For example, the maximum number of times of tuning reported by the terminal device is N4, which indicates that the bandwidth of the BWP of the terminal device may not include the first resource. For example, N3 is less than N4. For example, N3 is less than or equal to the first threshold value NN. For example, N4 is greater than or equal to the first threshold value NN. For example, NN is a positive integer.

In this embodiment, the maximum number of times of tuning supported by the terminal device in the first time period is indicated by reporting the second information, that is, the number of times of tuning that the first terminal device does not expect to occur in the first time period exceeds the maximum number of times of tuning supported by the first terminal device. Therefore, the frequency of switching the BWP by the terminal device is limited, the terminal device is prevented from switching the BWP or tuning the frequency too frequently, and the energy consumption of the terminal device is saved. Meanwhile, the limitation of the tuning times of the terminal equipment is determined according to the capability of the terminal equipment, and the flexibility of scheduling and configuration is increased for the base station.

As an alternative embodiment, the third BWP does not include the first resource. E.g., the second BWP is the active BWP or the initial BWP. For example, the network device configures the tuning number of the terminal device in the second time period to be less than or equal to P. For example, the number of times the terminal device is not required (undesired) to tune in the second time period is greater than or equal to P. For example, the number of times that the terminal device is configured by the network device to receive the first resource in the second time period is less than or equal to P. For example, the number of times the terminal device is not required (not expected) to receive the first resource in the second time period is greater than or equal to P. For example, the second time period includes M2 time units. M2 is a positive integer.

On the other hand, the terminal device reports third information to the network device, where the third information is used to indicate whether the terminal device supports performing first measurement by using the non-cell-defined NCD SSB, and the first measurement includes at least one of RRM (radio resources monitoring) measurement, RLM (radio link monitoring) measurement, SINR (signal interference noise ratio) measurement, mobility measurement, beam correlation measurement, BFR (beam failure recovery) measurement, or BM (beam management) measurement. And reporting the third information to assist the terminal equipment in reducing the complexity, wherein if the terminal equipment wants to reduce the complexity or considers that the complexity caused by switching is higher, the terminal equipment can report that the first measurement is not supported by the non-cell-defined NCD SSB. If the terminal device considers that the complexity caused by the handover is not high or it wants to acquire the possibility of communicating with the network device in a larger bandwidth range, the terminal device may report support for performing the first measurement through the non-cell-defined NCD SSB.

On the other hand, the terminal device reports fourth information to the network device, where the fourth information is used to indicate whether the terminal device supports the third BWP. E.g., the third BWP is the active BWP or the initial BWP. E.g. the third BWP is an independent initial BWP. For example, the fourth information is used to indicate whether the terminal device supports the configured third BWP. E.g. meaning that the terminal device may be configured with BWP in which the bandwidth does not comprise the first resource, or meaning that the terminal device does not comprise the first resource within the bandwidth supporting BWP, or meaning that the terminal device supports the first measurement by NCD SSB. For example, the terminal device reports that the third BWP is not configured, which means that the terminal device cannot be configured with BWP whose bandwidth does not include SSB, or means that the terminal device does not include the first resource in the bandwidth that does not support BWP, or means that the terminal device does not support the first measurement by NCD SSB. And reporting the fourth information to assist the terminal device in reducing the complexity, wherein if the terminal device wants to reduce the complexity or considers that the complexity caused by the handover is high, the terminal device may report that the third BWP is not supported. If the terminal device considers that the complexity caused by the handover is not high or wants to acquire the possibility of communicating with the network device in a larger bandwidth range, the terminal device may report that the third BWP is supported.

On the other hand, if the second time period configured by the network device is less than or equal to the second threshold, the terminal device does not expect that the first bandwidth does not include the first resource. For example, the first bandwidth does not include the first resource, and the second time period should be configured to be greater than or equal to the second threshold. E.g., (the bandwidth of) the initial BWP, (the bandwidth of) the independent initial BWP, (the bandwidth of) the RRC-configured BWP or (the bandwidth of) the terminal device-specific BWP. For example, the terminal device may be a terminal device that does not include the first resource for bandwidth supporting BWP, or a low complexity terminal device. For example, the second time period may be M3 time units. M3 is a positive integer.

E.g., the second time period is network indicated or predefined. For example, the second time period may be associated with the first measurement, or the second time period may be greater than the time required for the first measurement, or the first measurement may be taken during the second time period. For example, the second threshold value is a predefined value. For example, the second threshold is 10ms, 20ms, 10 slots, 64 slots, 1 frame, 1 radio frame, or 1 measurement period. For example, the terminal device supports the first bandwidth without including the first resource, and the second threshold is 1 frame. For example, the terminal device does not support the first bandwidth without the first resource, and the second threshold is 2 frames.

For example, the second threshold value is determined based on the terminal device capabilities. And if so, the terminal equipment reports the value of the second threshold. For example, the terminal device reports the minimum time interval between two supported tunings, i.e. the second threshold. For example, when the terminal device reports that the first bandwidth does not include the first resource, the minimum second time period is supported.

As shown in fig. 1, the network device is configured with the second time period being less than or equal to the second threshold, and the first bandwidth includes the first resource. That is, the configuration of the network device is limited, and the first bandwidth must include the first resource. As shown in fig. 2, the network device is configured with the second time period being greater than or equal to the second threshold value, and the first bandwidth may not include the first resource. That is, the network device may determine that the first bandwidth must include the first resource based on whether the network resource is congested. As in fig. 3, the first bandwidth includes the first resource and the second time period may be less than or equal to the second threshold value. As shown in fig. 3, the first bandwidth does not include the first resource, and the terminal device does not expect the second time period to be less than or equal to the second threshold, or the second time period to be greater than or equal to the second threshold.

In this embodiment of the present application, the first information, the second information, the third information, and the fourth information may be sent independently or in combination, and when multiple pieces of information are sent, the first information, the second information, the third information, and the fourth information may be carried in the same message or different messages.

In a possible implementation, the second information, the third information, or the fourth information may be reported independently without depending on the reporting of the first information, for example, the terminal device may only report the second information without reporting the first information (that is, the terminal device does not need to perform step 301), and the maximum tuning times supported by the terminal device in the first time period may be indicated by the second information, so as to implement flexible configuration of the network device.

In the embodiment of the application, the terminal device may report the first information to the network device at different occasions. Specifically, the terminal device may report the first information to the network device when the terminal device is in an RRC idle state, an RRC inactive state, or an RRC connected state, which will be described below.

RRC connected state (RRC _ CONNECT), which may also be referred to herein simply as connected state. RRC IDLE state (RRC _ IDLE), which may also be referred to herein simply as IDLE state. The RRC INACTIVE state (RRC _ INACTIVE), may also be referred to herein as INACTIVE state, or INACTIVE state.

If the terminal device is in a connected state, and the terminal device has established uplink and downlink synchronization and connection with the network device at this time, the terminal device may report the first information through a Radio Resource Control (RRC) message. The network device may actively initiate an instruction for acquiring the first information to the terminal device, so that the terminal device responds to the network device to complete the reporting of the first information, or the terminal device may also actively initiate the reporting of the first information without an instruction of the network device.

The format content of the first information can be various and can be defined according to the needs of the actual application. For example, the first information includes 1bit. For example, the first message is carried in an RRC message. If the bit state of the RRC message is "1", the first information indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource. If the bit state is "0", the first information indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource. For another example, the first information includes 1bit. E.g. the bandwidth of the initial BWP of the default terminal device needs to include the first resource. If the terminal device does not report the first information, it indicates that the bandwidth of the initial BWP of the terminal device needs to include the first resource. If the terminal device reports the first information, it indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource.

The network device, after determining the first message of the terminal device, may configure the frequency range of the first initial BWP and/or include the first resource according to the indication of the first information (whether the bandwidth of the initial BWP of the terminal device may not include the first resource) such that the terminal device communicates with the network device on the first initial BWP. In this embodiment, the terminal device reports the first information in the connected state, the first information may be carried in the RRC message for reporting, and the RRC message is transmitted more stably, and communication resources in the random access process performed by other terminal devices are not occupied, so that the occupation of resources is reduced.

If the terminal device is in an idle state or an inactive state, the terminal device and the network device need to acquire uplink synchronization and downlink synchronization in order to acquire connection with the network device. When the terminal device decodes the SSB, it has already acquired downlink synchronization, and the terminal device needs to initiate Random Access Channel (RACH) to the network device in order to establish uplink and downlink synchronization and Radio Resource Control (RRC) connection. In practical applications, the Random Access method of the terminal device can be divided into a Random Access procedure Based on Contention (CBRA) and a Random Access procedure Based on Non-Contention-or-Contention-Free Random Access (CFRA). The communication method provided by the present application is applicable to the random access procedure in any manner, and is not limited herein.

In the embodiment of the present application, during the random access process, the network device may first transmit the configuration information of the configured initial BWP to the terminal device through a system message or SSB. After acquiring the information, the terminal device determines the first initial BWP for random access according to whether the bandwidth of the initial BWP of the terminal device may not include the first resource. Illustratively, the network device may send configuration information of two initial BWPs to the terminal device through a system message or SSB, where a bandwidth of one initial BWP includes the first resource (BWP 1) and a bandwidth of the other initial BWP does not include the first resource (BWP 2). E.g. one initial BWP is an independent initial BWP and one initial BWP is a non-independent initial BWP. After receiving the configuration information of the two initial BWPs, the terminal device selects one of the initial BWPs for random access according to its first capability, that is, according to whether the bandwidth of the initial BWP of the terminal device may not include the first resource. If the bandwidth of the initial BWP of the terminal device may not include the first resource, the terminal device initiates the random access procedure with BWP2 (whose bandwidth is the initial BWP that does not include the first resource) as the first initial BWP. The terminal device initiates a random access procedure from BWP2 (independent initial BWP), which is equivalent to reporting the first information on BWP2, or equivalent to reporting the first information on a random access resource of BWP 2. Wherein the first information indicates that the bandwidth of the initial BWP of the terminal device may not include the first resource. If the bandwidth of the initial BWP of the terminal device needs to include the first resource, the terminal device initiates a random access procedure with BWP1 (whose bandwidth is the initial BWP including the first resource) as the first initial BWP. The terminal device initiates a random access procedure from BWP1 (dependent initial BWP), which is equivalent to reporting the first information on BWP1, or equivalent to reporting the first information on a random access resource of BWP 1. Wherein the first information indicates that the bandwidth requirement of the initial BWP of the terminal device includes a first resource.

And when the terminal equipment is in an idle state or an inactive state, the first information can be carried in the random access message for reporting. Specifically, the first message may be carried in at least one of Msg1, msg3, msgA, or Msg5 in the random access process to complete reporting. In this embodiment, the terminal device reports the first information during the random access process, so as to directly determine the first initial BWP that needs to communicate with the network device in the random access phase, thereby improving the implementation efficiency of the scheme.

In practical applications, when the terminal device is in an idle state or an inactive state, since the terminal device has not established an RRC connection with the network device, the requirement for data delay is not high for the terminal device in the idle state or the inactive state. Therefore, if the first information of the terminal device indicates that the initial BWP of the terminal device needs to include the first resource, i.e. the terminal device does not support the independent initial BWP, or even if the independent initial BWP does not include the first resource, in the present application, the network device can communicate with the terminal device on the independent initial BWP at any time, at the cost that the terminal device needs to switch to the first resource and then switch back to the independent initial BWP again whenever information such as SSB needs to be acquired. In other words, in the embodiment of the present application, as long as the terminal device is still in the idle state or inactive state, the communication may be established through the independent initial BWP. The difference is that the terminal device may be configured with a separate initial BWP directly to communicate with the network device if the initial BWP for the terminal device may not include the first resource. If the initial BWP of the terminal device needs to include the first resource, the BWP on which the terminal device operates may be frequently switched to maintain communication, i.e. the terminal device needs to switch to the first resource whenever it needs to acquire information such as SSB, and then switch back to the independent initial BWP again.

A possible embodiment is to obtain configuration information for a fourth BWP, the bandwidth of which does not comprise the first resource. For example, the configuration information of the fourth BWP includes bandwidth information of the fourth BWP. For example, the network device transmits configuration information for the fourth BWP. For example, the terminal device receives configuration information for the fourth BWP. E.g. the fourth BWP is the initial BWP, or is a stand-alone initial BWP, or is an active BWP, or is a UE specific BWP. For example, the fourth BWP is the independent downlink initial BWP.

For example, the terminal device camps on the fourth BWP. For example, when the terminal device is camped on the fourth BWP, the terminal device listens for information on the fourth BWP in the idle state. E.g., the fourth BWP comprises the first resource, the terminal device camping on the fourth BWP. For example, the fourth BWP does not include the first resource and the terminal device does not reside in the fourth BWP. For example, the fourth BWP does not include the first resource, and the terminal device does not reside in the fourth BWP but in the initial BWP configured in the MIB or in a non-independent initial BWP. In this application, monitoring is also understood to mean monitoring, detecting, receiving, which may be interchangeable or generic.

For example, the terminal device receives the first type of common information on the fourth BWP. For example, the terminal device does not receive the second type of common information on the fourth BWP.

For example, the first type of common information is random access information. For example, the second type of common information is at least one of system information, DCI (Downlink control information) for scheduling paging information, DCI for scheduling paging information, and SSB. For example, the system information includes at least one of system information block 1 (SIB 1) and other system information (other SIB). For example, the random access information includes at least one of a Random Access Response (RAR), a DCI scheduling the RAR, a DCI scheduling the Msg3 transmission, a DCI scheduling the Msg4, and Msg 4. For example, paging and system information are received at the terminal device at core set #0 (not at the fourth BWP). For example, the terminal device receives random access information in a fourth BWP. The reason for this is that SSB and/or system information needs to be received before the idle terminal device receives paging information, and system information may need to be received after the connected terminal device receives paging information, and if these are not configured in the same BWP, the UE needs to tune back and forth frequency, which is prone to cause missed detection.

For example, the first type of common information is a random access procedure triggered in response to a first type of event. For example, the second type of common information is a random access procedure triggered in response to a second type of event.

As in 1, the first type of event is an SR-related event. For example, the SR-related event is SR failure, or SR is not configured for the terminal device, or there is no available SR when uplink data arrives. For example, the second type of event is a non-SR related event. For example, the second type of event is a beam failure (beam failure). For example, the second type event is RRC connection reestablishment. For example, the second type event is that the uplink of the terminal equipment is out of synchronization when uplink or downlink data arrives.

As shown in fig. 2, the random access procedure triggered by the first type event is a random access procedure that does not require detection of SSBs before initiating the random access procedure. For example, the random access procedure triggered by the beam failure recovery, and the reference signal detected when the beam failure is configured is CSI-RS. That is, the random access procedure is preceded by only the detection of CSI-RS, and not by the detection of SSB. For example, detection can also be understood as reception or monitoring. For example, the random access procedure triggered by the second type of event is a random access procedure that requires detection of an SSB before initiating the random access procedure. E.g., a random access procedure triggered by a beam failure recovery, and the reference signal detected when the beam fails is configured to be SSB. I.e. the detection of SSBs is required before the random access procedure.

Has the advantages that: determining which scenes need to be tuned to the dependent initial BWP according to the event reduces the number of tuning times and also shunts common information or common channels to avoid congestion.

For example, the terminal device monitors the first type of control channel on the fourth BWP. For example, the terminal device does not monitor the second type of control channel on the fourth BWP.

For example, the first type of control channel is used to carry at least one of DCI scheduling RAR, DCI scheduling Msg3 transmission, and DCI scheduling Msg 4. For example, the second type of control channel is used for carrying at least one of scheduling system information DCI and DCI of scheduling paging information. For example, the terminal device monitors the control channel for paging and system information at CORESET #0 (not at the fourth BWP). For example, the terminal device monitors the control channel for random access information at the fourth BWP. The reason for this is that SSB and/or system information needs to be received before the idle terminal device receives paging information, and system information may need to be received after the connected terminal device receives paging information, and if these are not configured in the same BWP, the UE needs to tune back and forth frequency, which is prone to cause missed detection.

For example, a first type of control channel is used for DCI carrying a RAR of a random access procedure triggered in response to a first type of event. For example, the second type of control channel is used for DCI carrying a RAR of a random access procedure triggered in response to a second type of event.

On the basis of the embodiment corresponding to fig. 3, in order to better implement the above-mentioned solution of the embodiment of the present application, the following also provides a related apparatus for implementing the above-mentioned solution. Specifically, please refer to fig. 6, where fig. 6 is a schematic structural diagram of a communication device according to an embodiment of the present application, the communication device includes:

a processing module 601, configured to report first information to a network device, where the first information indicates that a bandwidth of an initial partial bandwidth BWP of a communication apparatus may not include a first resource, or the first information indicates that the bandwidth of the initial BWP of the communication apparatus needs to include the first resource, where the first resource includes at least one of a resource of a synchronization signal block SSB, a resource of a common search space, a resource of a control resource set, a resource of a channel state information reference signal, or a resource of a tracking reference signal;

it should be noted that, in this embodiment, there are various ways for the processing module 601 to report the first information. The reporting of the first information by the processing module 601 may be implicit reporting to the network device, for example, the bandwidth of the initial partial bandwidth BWP of the default terminal device of the network device may not include the first resource, if the terminal device does not send an indication of the first information to the network device, that is, the processing module 601 reports the first information to the network device, where the first information indicates that the bandwidth of the initial partial bandwidth BWP of the communication apparatus may not include the first resource.
