Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technology but is not limited to the field of wireless communication technology, and in particular to a bandwidth resource multiplexing method and apparatus, communication equipment, and storage medium. Background Art

[0002] In the fourth generation of mobile communication (4 th In the 4G (4th Generation) system, two technologies, Machine Type Communication (MTC) and Narrow Band Internet of Things (NB-IoT), were proposed to support IoT services. These two technologies are mainly aimed at low-rate, high-latency scenarios, such as meter reading and environmental monitoring. NB-IoT currently only supports a maximum rate of several hundred k, and MTC currently only supports a maximum rate of several M. But on the other hand, with the continuous development of IoT services, such as video surveillance, smart home, wearable devices and industrial sensor monitoring, these services usually require a rate of tens to 100M, and also have relatively high requirements for latency, so it is difficult for MTC and NB-IoT technologies in LTE to meet the requirements. Based on this situation, many companies have proposed to design a new user equipment in the 5G New Radio (NR) to cover this mid-range IoT device. At present, this new terminal type is called Reduced Capability (Redcap) UE.

[0003] Thus, in wireless cellular communication, there exist at least two types of UEs with different supported bandwidths and required delays. How to use wireless resources for these two types of UEs can reduce unnecessary resource waste and communication capacity reduction. Summary of the invention

[0049] Please refer to Figure 1 , which shows a schematic structural diagram of a wireless communication system provided by the embodiments of the present disclosure. As Figure 1 shown, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include: a plurality of UEs 11 and a plurality of base stations 12.

[0050] Among them, the UE 11 may be a device that provides voice and / or data connectivity to a user. The UE 11 may communicate with one or more core networks via a radio access network (RAN). The UE 11 may be an Internet of Things UE, such as a sensor device, a mobile phone (or referred to as a "cellular" phone), and a computer with an Internet of Things UE. For example, it may be a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote UE, an access terminal, a user terminal, a user agent, a user device, or a user UE (user equipment, UE).

Alternatively, the UE 11 may also be a roadside device, such as a street lamp, a traffic signal, or other roadside devices with wireless communication capabilities.

[0051] The base station 12 may be a network-side device in a wireless communication system. Among them, the wireless communication system may be a fourth-generation mobile communication technology (4G) system, also known as the Long Term Evolution (LTE) system; or, the wireless communication system may also be a 5G system, also known as the new radio (NR) system or 5G NR system. Or, the wireless communication system may also be the next-generation system of the 5G system. Among them, the access network in the 5G system may be called the NG-RAN (New Generation-Radio Access Network, new generation wireless access network). Or, the MTC system.

[0057] As Figure 2 shown, the embodiments of the present disclosure provide a bandwidth resource reuse method, which includes:

[0058] S210: Send down resource configuration parameters; the resources indicated by the resource configuration parameters can be used for bandwidth resource reuse of the first type of UE and the second type of UE;

[0059] Among them, the bandwidth resource reuse includes at least one of the following:

[0060] The physical random access channel PRACH resources of the first type of UE and the second type of UE partially overlap or completely overlap, and

[0061] The initial uplink UL bandwidth part BWP of the first type of UE and the second type of UE partially overlap or completely overlap.

[0062] Of course, the resources for reuse can be not only PRACH resources and / or the initial UL BWP, but also any other appropriate resources, and the embodiments of the present disclosure do not limit this.

[0063] A method for multiplexing bandwidth resources provided by an embodiment of the present disclosure can be applied to an access device on the network side. The access device includes but is not limited to various types of base stations, such as evolved base stations (eNBs) and / or next-generation base stations (gNBs) and / or base stations of any generation of communication systems.

[0064] The resource configuration parameters here can be the configuration parameters for configuring communication resources for use by a terminal.

[0065] The communication resources include but are not limited to:

[0066] Time-domain resources;

[0067] Frequency-domain resources;

[0068] Time-domain frequency-domain resources;

[0069] Bandwidth resources;

[0070] Code-domain resources, such as random access preambles or space division multiplexing codes, etc.

[0071] In the embodiments of the present disclosure, in order to improve resource utilization rate, the resources indicated by the resource parameters sent to different types of UEs can be reused by the first type of UE and the second type of UE. In the embodiments of the present disclosure, after classifying UEs, there can be multiple types of UEs, that is, including but not limited to the first type of UE and the second type of UE, which will not be elaborated here.

[0072] Different types of UEs can be distinguished according to the supported bandwidth. For example, the second type of UE supports a large bandwidth, while the first type of UE supports a small bandwidth. In some embodiments, the second type of UE can be a common UE, while the first type of UE can be a UE with reduced capabilities.

[0073] Different types of UEs can also be distinguished according to the transceiver capabilities of the UEs. For example, some UEs have only a single antenna and cannot perform uplink transmission and downlink transmission simultaneously, so they may need to perform uplink-downlink switching when receiving data. Some UEs have multiple antennas and can perform uplink transmission and downlink transmission simultaneously.

[0074] Different types of UEs can also be distinguished according to the service functions corresponding to the UEs. For example, for smart home devices such as smart water meters and smart office devices such as smart printers, and mobile phones for communication with them, they belong to different functional types of UEs.

[0075] Due to differences in communication among different types of UEs, if the communication quality of each type of UE needs to be optimized, it may be necessary to allocate resources separately for these UEs, which will result in low utilization of communication resources and reduced system capacity. In the embodiments of the present disclosure, to address the issue of allocating communication resources specifically for each type of UE, the first type of UE and the second type of UE can reuse resources. The resources subject to reuse include, but are not limited to, resources of the Physical Random Access Channel (PRACH) (i.e., PRACH resources) and the initial UL BWP. For PRACH and the initial UL BWP, the resources corresponding to different types of UEs can partially or fully overlap. Taking the initial UL BWP as an example, the resources corresponding to the first type of UE and the second type of UE can partially or fully overlap. In some embodiments of the present disclosure, PRACH resources can be used for the random access of UEs. In some embodiments of the present disclosure, the initial UL BWP can be used for the initial access of UEs.

[0076] In some embodiments of the present disclosure, UEs can be classified into two or more categories.

[0077] In the embodiments of the present disclosure, the first type of UE and the second type of UE can perform partial or full reuse of PRACH resources based on the resource configuration parameters sent by the base station, and / or the first type of UE and the second type of UE can perform partial or full reuse of the resources of the initial UL BWP based on the resource configuration parameters sent by the base station.

[0078] In this way, at least two types of UEs can reduce resource waste and improve system capacity through the reuse of at least some resources of PRACH resources and / or BWP.

[0079] In some embodiments, the at least two types of UEs include: the first type of UE and the second type of UE; the bandwidth of the first type of UE is less than the bandwidth supported by the second type of UE.

[0080] For example, the first type of UE can be a Redcap UE (Reduced capability UE); the second type of UE can be an NR UE.

[0081] Redcap UE has the following characteristics: low cost, low complexity, enhanced coverage to a certain extent, and low power consumption.

[0082] For example, to meet requirements such as low cost and low complexity, the radio frequency (RF) bandwidth of Redcap can be restricted, such as restricted to 5 MHz or 10 MHz, or the buffer capacity of Redcap can be restricted, thereby restricting the size of each received transport block, etc. For power saving, possible optimization directions are to simplify the communication process and reduce the number of times Redcap UE detects the downlink control channel, etc.

[0083] In summary, in one embodiment, different types of UEs are divided according to the bandwidth supported by the UE. For example, they are divided according to the maximum bandwidth supported by the UE.

[0084] In some embodiments of the present disclosure, the first type of UE and the second type of UE can reuse at least part of the PRACH resources, and / or the first type of UE and the second type of UE can reuse at least part of the initial UL BWP.

[0085] In one embodiment, the resource configuration parameters include:

[0086] At least one set of configuration parameters, and this at least one set of configuration parameters is the configuration parameters dedicated to the first type of UE.

[0087] In one embodiment, the resource configuration parameters include: at least two sets of configuration parameters, where at least one set of resource parameters corresponds to the first type of UE.

[0088] In some embodiments of the present disclosure, taking the UE including the first type of UE and the second type of UE as an example for illustration; of course, it may also include other types of UEs, and the embodiments of the present disclosure do not make limitations in this regard. In some embodiments of the present disclosure, the resource configuration parameters at least include: the first set of configuration parameters for the first type of UE; the second set of configuration parameters for the second type of UE.

[0089] In this way, when the base station issues the resource configuration parameters, it can broadcast the resource configuration parameters carrying multiple sets of configuration parameters to all UEs in the cell at the same time, or can separately send at least one set of configuration parameters corresponding to a certain type of UE to that type of UE. For example, multicast or unicast the first set of configuration parameters corresponding to the first type of UE to the first type of UE group, and multicast or unicast the second set of configuration parameters corresponding to the second type of UE to the second type of UE.

[0090] In some embodiments of the present disclosure, the resource configuration parameters include one set or multiple sets of configuration parameters, where any one set of the configuration parameters may include at least one of the following:

[0091] An indication parameter of the random access preamble set, where the random access preambles corresponding to the random access preamble sets of the first type of UE and the second type of UE are different;

[0092] Resource parameters of the PRACH resource, where the PRACH resources corresponding to the first type of UE and the second type of UE at least partially overlap;

[0093] Resource parameters of the initial UL BWP, where the initial UL BWPs corresponding to the first type of UE and the second type of UE at least partially overlap;

[0094] The mapping relationship between the synchronization signal block SSB and the PRACH resource, so that the first type of UE and / or the second type of UE determine the used PRACH resource according to the accessed SSB; and

[0095] The indication parameter of the mapping relationship between the PRACH resource and the initial UL BWP, so that the first type of UE and / or the second type of UE determine the used initial UL BWP according to the used PRACH resource.

[0096] In some embodiments of the present disclosure, the resource configuration parameter may be an indication parameter of a random access preamble set, where the random access preambles corresponding to the random access preamble sets corresponding to the first type of UE and the second type of UE are different. In some embodiments of the present disclosure, each random access preamble set may include one or more random access preambles. Since at least two types of UEs multiplex the PRACH resource and / or the initial UL BWP indicated by the resource configuration parameter, in order to facilitate the base station to distinguish which type of UE is currently accessing from the multiplexed PRACH resource, different random access preamble sets will be assigned to different types of UEs.

[0097] In some embodiments of the present disclosure, the indication parameter may be a set index of the random access preamble set; or an index of the random access preamble included in the random access preamble set, etc. In some embodiments of the present disclosure, the index of the random access preamble / random access preamble set may be specified by the communication protocol or configured by the network side for the UE. In some embodiments of the present disclosure, the indication parameter may be the random access preamble / random access preamble set itself corresponding to the first type of UE and / or the second type of UE.

[0098] In some embodiments of the present disclosure, the foregoing random access preamble / random access preamble set index and the foregoing random access preamble / random access preamble set itself may also be used in combination; that is, the indication parameter includes both the random access preamble / random access preamble set index and the random access preamble / random access preamble set itself; or the indication parameter includes the random access preamble / random access preamble set index corresponding to a part of UEs and also includes the random access preamble / random access preamble set itself corresponding to a part of UEs.

[0099] In summary, the indication parameter may be various information or data for indicating to the UE the random access preamble / random access preamble set configured for it.

[0100] One of the random access preamble sets includes one or more random access preambles. Different random access preamble sets contain different random access preambles. Therefore, when the base station receives a random access request on a PRACH resource multiplexed by multiple types of UEs, it determines the type of the UE currently requesting random access according to the indication parameter of the random access preamble set to which the random access preamble carried in the random access request belongs, and then comprehensively determines whether to respond to the random access of the UE according to the type of the UE, the quality of service (QoS) of the service corresponding to this type of UE, the current network load condition, the access rate of various types of UEs, etc.

[0101] In one embodiment, the resource parameter of the PRACH resource indicates the PRACH resource. For example, the resource parameters of the PRACH resources configured for each type of UE. The resource parameter can indicate the resources of the PRACH, including at least one of the following: time domain resources, frequency domain resources, and code domain resources.

[0102] The resource parameters of the initial UL BWP can indicate the resources for the corresponding type of UE to perform initial access, including at least one of the following: time domain resources, frequency domain resources, and code domain resources.

[0103] When the UE accesses, it needs to perform downlink synchronization with the network side. The base station on the network side will send down a synchronization signal block, and the synchronization signal block includes, but is not limited to: a primary synchronization signal and / or a secondary synchronization signal.

[0104] To reduce the sliding of the bandwidth frequency supported by the UE, there is a certain correlation between the SSB, PRACH resources, and the initial UL BWP of the same type of UE. For example, at least part of the bandwidth of the SSB is covered by the bandwidth of the PRACH resources, and at least part of the bandwidth of the initial UL BWP covers at least part of the bandwidth of the PRACH resources used by the UE. Therefore, in one embodiment, the resource configuration parameter may indicate the mapping relationship between the SSB and the PRACH resources.

[0105] For example, if N PRACH resources are configured through the resource parameters of the PRACH resources, and there is a mapping relationship between one SSB and one PRACH resource, then after the UE accesses from one of the N SSBs, according to this mapping relationship, it selects the PRACH resource corresponding to the SSB it accesses for random access. Of course, in another embodiment, one SSB may correspond to multiple PRACH resources.

[0106] Reference Figure 3As shown, the resource configuration parameters configure 4 SSBs, namely SSB1 to SSB4. One SSB corresponds to 2 PRACH resources.

[0107] Reference Figure 4A As shown, 4 SSBs are configured for enhanced mobile broadband (eMBB) UEs, and one SSB corresponds to 2 PRACH resources. 4 SSBs are also configured for Redcap UEs, and among them, these 4 SSBs respectively correspond to one PRACH resource.

[0108] The eMBB UE here is a type of the aforementioned second type of UE.

[0109] And in this way, it can be known that the first type of UE multiplexes part of the PRACH resources of the second type of UE, and the part of the PRACH resources multiplexed by the first type of UE is continuously distributed in the frequency domain.

[0110] In one embodiment, the bandwidths of the PRACH resources used by two types of UEs supporting different bandwidths can be the same or different. For example, in one embodiment, the bandwidth of the PRACH resources used by the first type of UE for random access can be less than the bandwidth of the PRACH resources used by the second type of UE for random access.

[0111] In some other embodiments of the present disclosure, since the first type of UE and the second type of UE support different bandwidths, the bandwidths of the initial UL BWPs used by these at least two types of UEs are different. For example, the bandwidth of the initial UL BWP used by the first type of UE is less than that used by the second type of UE.

[0112] In some embodiments of the present disclosure, the resource configuration parameters include:

[0113] The third set of configuration parameters corresponding to the first type of UE and the second type of UE.

[0114] In other words, the resource configuration parameters include: the third set of configuration parameters corresponding to both the first type of UE and the second type of UE.

[0115] In some embodiments of the present disclosure, the resource configuration parameters at least include a set of resource configuration parameters that can correspond to the first type of UE and the second type of UE. That is, different types of UEs share the same set of resource configuration parameters.

[0116] Therefore, different types of UEs all receive the third set of configuration parameters. When performing resource multiplexing, resource multiplexing is carried out according to the resource multiplexing mechanism corresponding to its own type according to the resource configuration parameters.

[0117] For example, the third set of configuration parameters is configured to support the second type of UE with large bandwidth. When the first type of UE receives the third set of configuration parameters, according to the third set of configuration parameters and its own resource reuse mechanism for the PRACH resources and / or the initial UL BWP of the first type of UE, it reuses some or all of the PRACH resources of the second type of UE, and / or reuses some or all of the initial UL BWP of the second type of UE.

[0118] By adopting such resource configuration parameters, since resources are not separately configured for each type of UE to obtain resource parameters, the signaling overhead is reduced.

[0119] In some embodiments, the third set of configuration parameters includes at least one of the following:

[0120] An indication parameter corresponding to the random access preamble sets of the first type of UE and the second type of UE respectively;

[0121] A resource parameter corresponding to the PRACH resources of the first type of UE and the second type of UE at the same time;

[0122] An indication parameter corresponding to the mapping relationship between the SSB and the PRACH resources of the first type of UE and the second type of UE at the same time.

[0123] Similarly, the third set of configuration parameters here includes indication parameters for the random access preamble sets of different types of UEs, so that the network side can distinguish the device type of the current random access request according to the random access preamble carried in the random access request.

[0124] Of course, in some other embodiments, the indication parameter of the random access preamble set included in the third set of configuration parameters can also be for different types of UEs. In this case, different types of UEs will use the random access preambles in the same random access preamble set for random access. Subsequently, when the base station needs to determine the type of the UE, it can be determined through the information content sent by the UE after random access or during the random access process.

[0125] For the relevant descriptions of the indication parameter, resource parameter, and mapping relationship of the random access preamble set here, reference can be made to the foregoing embodiments, and details will not be repeated here.

[0126] In some embodiments, the mapping relationship between the SSB and the PRACH resources is used to enable the UE to determine the used PRACH resources according to the accessed SSB.

[0127] The mapping relationship between the SSB and the PRACH resources can be applicable to both the first type of UE and the second type of UE. Therefore, after receiving the mapping relationship indicated by the third set of configuration parameters, the UE can perform random access on the PRACH resources corresponding to the accessed SSB corresponding to the type of the UE according to the mapping relationship.

[0128] In the embodiments of the present disclosure, at least two types of different UEs can adopt the same mapping relationship between the SSB and the PRACH resources to determine the PRACH resources for the UE to perform random access.

[0129] In some embodiments, the third set of configuration parameters further includes:

[0130] The mapping relationship between the PRACH resources corresponding to the second type of UE and the initial UL BWP.

[0131] For example, taking the first type of UE and the second type of UE as an example, since the bandwidth supported by the second type of UE is greater than the bandwidth supported by the first type of UE. Therefore, at this time, the indication parameter of the mapping relationship carried in the third set of configuration parameters can be the mapping relationship between the PRACH resources of the second type of UE and the initial UL BWP.

[0132] In some embodiments of the present disclosure, the indication parameter of this mapping relationship can include an index indication indicating the mapping relationship, or can be reflected by the association relationship between the resource index of the PRACH resource and the initial UL BWP.

[0133] In some embodiments, the sending of the resource configuration parameters includes:

[0134] Sending the resource configuration parameters through the remaining minimum system information RMSI.

[0135] In some embodiments of the present disclosure, the resource configuration parameters are sent through the RMSI. In other embodiments of the present disclosure, the resource configuration parameters can also be sent through the RRC message or the MAC CE.

[0136] Such as Figure 5A As shown, the embodiments of the present disclosure provide a bandwidth resource multiplexing method, which is applied to a user equipment UE and includes:

[0137] S510: Receiving resource configuration parameters; where the resources indicated by the resource configuration parameters can be used for bandwidth resource multiplexing of the first type of UE and the second type of UE;

[0138] Wherein, the bandwidth resource multiplexing includes at least one of the following:

[0139] The physical random access channel (PRACH) resources of the first type of UE and the second type of UE partially overlap or completely overlap.

[0140] Or

[0141] The initial uplink (UL) bandwidth part (BWP) of the first type of UE and the second type of UE partially overlaps or completely overlaps.

[0142] The embodiments of the present disclosure are applied to UEs, including but not limited to the first type of UE and the second type of UE. The UE can be various types of UEs. The bandwidth supported by the second type of UE is greater than the bandwidth supported by the first type of UE, or the bandwidth supported by the second type of UE is equal to the bandwidth supported by the first type of UE.

[0143] Here, the bandwidth supported by the first type of UE and the bandwidth supported by the second type of UE can be respectively considered as: the maximum bandwidth that the first type of UE can operate on and the maximum bandwidth that the second type of UE can operate on.

[0144] In summary, different types of UEs will receive resource configuration parameters from the base station, and then according to the resource configuration parameters; in this way, different types of UEs can reuse resources; for example, perform the reuse of PRACH resources and / or the reuse of the initial UL BWP.

[0145] In an embodiment of the present disclosure, the UE receives a set of configuration parameters for the type of UE sent by the base station according to its own type. In another embodiment of the present disclosure, the resource configuration parameters sent by the network side device (such as the base station) are for multiple types of UEs, so the UE receives the resource configuration parameters for multiple types of UEs. For example, the resource configuration parameters for multiple types of UEs are a set of the respective resource configuration parameters of at least two types of UEs; the UE determines the resource configuration parameters corresponding to the UE from them according to its own type. Another example is that multiple types of UEs share the same set of resource configuration parameters, and the UE determines the resource configuration parameters according to its own type.

[0146] In one embodiment, S510 may include:

[0147] Receive the configuration parameters of the type of the UE according to the type of the UE.

[0148] For example, UEs can be at least divided into the first type of UE and the second type of UE. If the current UE is the first type of UE, it receives the first set of configuration parameters for the first type of UE from the base station. If the current UE is the second type of UE, it receives the second set of configuration parameters for the second type of UE from the base station.

[0149] The resource configuration parameters include at least one of the following:

[0150] An indication parameter of a random access preamble set, where the random access preamble sets corresponding to the first type of UE and the second type of UE include different random access preambles;

[0151] Resource parameters of the PRACH resource, where at least a part of the PRACH resources corresponding to the first type of UE and the second type of UE overlap;

[0152] Resource parameters of the initial UL BWP, where at least a part of the initial UL BWPs corresponding to the first type of UE and the second type of UE overlap;

[0153] An indication parameter of the mapping relationship between the synchronization signal block SSB and the PRACH resource, where the mapping relationship between the SSB and the PRACH resource is used for the first type of UE and / or the second type of UE to determine the used PRACH resource according to the accessed SSB; and an indication parameter of the mapping relationship between the PRACH resource and the initial UL BWP, where the mapping relationship between the PRACH resource and the initial UL BWP is used for the first type of UE and / or the second type of UE to determine the used initial UL BWP according to the used PRACH resource.

[0154] In another embodiment, the S510 may include:

[0155] Receiving a third set of configuration parameters for at least two types of UEs simultaneously.

[0156] In some embodiments of the present disclosure, for multiple types of UEs performing bandwidth resource multiplexing, if the base station only sends one set of configuration parameters, then multiple types of UEs will all receive the same set of configuration parameters and then directly use the received configuration parameters.

[0157] The UE that receives the third set of configuration parameters, for some types of UEs, performs bandwidth resource multiplexing with other types of UEs according to at least one of the mechanism information of the resource multiplexing mechanism stored locally, the resource multiplexing mechanism specified by the communication protocol, and the received configuration parameters. For example, all or part of the PRACH resource is multiplexed, and / or all or part of the initial UL BWP resource is multiplexed.

[0158] In one embodiment, the third set of configuration parameters includes at least one of the following:

[0159] Indication parameters of the random access preamble sets respectively corresponding to the first type of UE and the second type;

[0160] Resource parameters of the PRACH resource corresponding to both the first type of UE and the second type of UE at the same time; and

[0161] An indication parameter corresponding to the mapping relationship between the SSB and PRACH resources of the first type of UE and the second type at the same time.

[0162] For the relevant description of the specific content carried by the third set of configuration parameters in the embodiments of the present disclosure, reference can be made to the embodiments on the base station side, which will not be elaborated here.

[0163] In some embodiments, the mapping relationship between the SSB and PRACH resources is used for the UE to determine the PRACH resources to be used according to the accessed SSB.

[0164] In some embodiments, in response to the resource configuration parameters including the third set of configuration parameters, at this time, different types of UEs can use PRACH resources with the same bandwidth size for random access, and determine the used PRACH resources according to the mapping relationship between the same SSB and PRACH resources.

[0165] In some embodiments, the third set of configuration parameters further includes: an indication parameter of the mapping relationship between the PRACH resources for the second type of UE and the initial UL BWP.

[0166] For example, the third set of configuration parameters directly indicates the mapping relationship between the initial UL BWP and the PRACH resources of the UE with the largest supported bandwidth among at least two types of UEs (for example, the second type of UE). Therefore, the second type of UE directly determines its own used initial UL BWP according to this mapping relationship indicated by the third set of configuration parameters. The first type of UE or other types of UEs can determine the used initial UL BWP according to the PRACH resources they use and the bandwidth they support.

[0167] For example, as Figure 5B shown, the method further includes:

[0168] S520: In response to the UE being the first type of UE, determine the initial UL BWP of the first type of UE according to the PRACH resources used by the first type of UE and / or the bandwidth supported by the first type of UE.

[0169] For example, if the first type of UE uses the PRACH resource m for random access, the width of its supported bandwidth can be extended from the PRACH resource m as the lowest frequency bandwidth resource to the high frequency direction, so as to determine its own used initial UL BWP.

[0170] For another example, the first type of UE can also use the PRACH resource m as the central bandwidth and extend it to the high frequency direction and the low frequency direction to its supported bandwidth width to obtain its own used initial UL BWP.

[0171] For another example, the first type of UE can also use the PRACH resource m as the highest frequency bandwidth resource and extend it to the bandwidth supported by itself in the low-frequency direction to obtain the initial UL BWP used by itself.

[0172] In one embodiment, the first type of UE can determine the direction of bandwidth width expansion according to its own indicated bandwidth based on the frequency of the PRACH resource used for the current random access. For example, if the PRACH resource used by the current first type of UE is the PRACH resource with the highest frequency configured by the third set of configuration parameters, the frequency expansion direction is determined to be the low-frequency direction. For another example, if the PRACH resource used by the current first type of UE is the PRACH resource with the lowest frequency configured by the third set of configuration parameters, the frequency expansion direction is determined to be the high-frequency direction. When the PRACH resource used currently is the intermediate frequency of the frequency configured by the third set of configuration parameters, a frequency expansion direction can be randomly determined, and the expansion direction can be the low-frequency direction, the high-frequency direction, or both the high-frequency and low-frequency directions simultaneously.

[0173] In some embodiments, the first type of UE can directly use the bandwidth that is a predetermined multiple of the PRACH resource it uses as its initial UL BWP. The predetermined multiple can be predefined, or specified by the communication protocol, or configured by the network-side device through a message. At this time, the PRACH resource used by the first type of UE can be used as a sub-band at any position in the initial UL BWP.

[0174] In some embodiments, the initial UL BWP finally used by the first type of UE can be a sub-band of the initial UL BWP of the second type of UE.

[0175] Refer to Figure 4B As shown, SSB1 corresponds to Figure 4B the bottom 2 PRACH resources. If the Redcap UE receives the synchronization signal sent by the base station from SSB1, it is determined to perform random access on the bottom 2 PRACH resources corresponding to SSB1. Further, based on the bottom 2 PRACH resources within Figure 4B , the Redcap UE slides up 2 PRACH resources to obtain the initial UL BWP1 shown in Figure 4B . Figure 4B As can be seen from

[0176] From Figure 4B it can be known that in this way, even if a UE supporting a narrow bandwidth is within the initial UL BWP of a UE supporting a larger bandwidth, according to the PRACH resource it uses and combined with its own supported bandwidth, it will obtain its own used initial UL BWP.

[0177] Reference Figure 4B As shown, according to this resource reuse mechanism, based on the PRACH resources on the initial UL BWP of the second type of UE and the bandwidth supported by the first type of UE, three initial UL BWPs available for the first type of UE can be obtained, which can be respectively as Figure 4B shown in the initial UL BWP1, initial UL BWP2, and initial UL BWP3. Refer to Figure 4B As shown, the first type of UE can evenly reuse different bandwidth resources as the initial UL BWP. Of course Figure 4B this is only an example, and the specific implementation is not limited to this.

[0234] Receiving the resource configuration parameters through the Remaining Minimum System Information (RMSI).

[0235] In some embodiments of the present disclosure, a solution for supporting the multiplexing of PRACH resources by Redcap UEs and normal NR terminals is provided. The following provides two alternative specific implementation solutions.

[0236] Method 1: Centralized multiplexing

[0237] The optional PRACH resources configured for all Redcap UEs are concentrated on some of the PRACH resources configured for normal NR terminals, as Figure 4A shown.

[0238] Configure the Initial UL BWP for Redcap in the RMSI. The PRACH resources allocated to normal terminals included in the initial UL BWP are the PRACH resources allocated to Redcap. Or directly configure the PRACH resources of Redcap UEs by the RMSI.

[0239] On the PRACH resources where the two types of terminals overlap, the two types of terminals use different sets of preambles. The preambles included in different sets of preambles are different. Therefore, the access network can determine whether the currently requesting access terminal is a Redcap terminal or an NR terminal according to the different preambles sent on the same PRACH resource.

[0240] Method 2: Refer to Figure 4B As shown, for dispersed multiplexing, configure multiple initial UL BWPs or PRACH resource groups, and multiple initial BWPs or PRACH resource groups include some PRACH resources allocated to normal NR terminals.

[0241] The Redcap UE selects which initial UL BWP or PRACH resource group to use according to specific criteria.

[0242] For example, the Redcap UE determines which PRACH resource and initial UL BWP to use based on the SSB used during access.

[0243] For the determination of multiple initial UL BWPs, it can be configured by RMSI or determined according to the PRACH resources selected by the terminal. For example, if the user equipment accesses through SSB1, then starting from the PRACH resource corresponding to SSB1 of the eMBB user equipment, the initial UL BWP is determined by adding the bandwidth of the user equipment, and the PRACH corresponding to SSB1 of the eMBB user is used for access.

[0244] Support the multiplexing of the PRACH resources of the Redcap UE and the PRACH resources of normal NR.
