FIG. 1 is a schematic structural diagram illustrating a wireless communication system according to an embodiment of the present disclosure. As shown in FIG. 1, the wireless communication system is a communication system based on the cellular mobile communication technology, which may include a plurality of terminals 11 and a plurality of base stations 12.

The terminal 11 may be a device that provides voice and/or data connectivity to users. The terminal 11 can communicate with one or more core networks via a radio access network (RAN). The terminal 11 can be an IoT terminal, such as a sensor device, a mobile phone (or a “cellular” phone) and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-built or on-board device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device or a user equipment (UE). Alternatively, the terminal 11 may be a device of an unmanned aerial vehicle. Alternatively, the terminal 11 may also be an on-board device, for example, a driving computer with wireless communication function, or a wireless communication device externally connected to the driving computer. Alternatively, the terminal 11 may also be a roadside device, such as a street lamp, a signal lamp or other roadside device with wireless communication function.

The base station 12 may be a network device in a wireless communication system. The wireless communication system can be the 4th (4G) generation mobile communication system, also known as long term evolution (LTE) system. Alternatively, the wireless communication system can also be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system can also be a next generation system of the 5G system. The access network in the 5G system can be called a new generation-radio access network (NG-RAN). Or, a machine type communication (MTC) system.

The base station 12 may be an evolved node B (eNB) adopted in the 4G system. Alternatively, the base station 12 may also be a g-node-B (gNB) adopting a centralized and distributed architecture in the 5G system. When the base station 12 adopts a centralized and distributed architecture, the base station 12 usually includes a central unit (CU) and at least two distributed units (DUs). The centralized unit is provided with a protocol stack of packet data convergence protocol (PDCP) layer, radio link control (RLC) layer and media access control (MAC) layer.

Alternatively, the network management device can also be other core network devices, such as serving gateway (SGW), public data network gateway (PGW), policy and charging rules function (PCRF) or home subscriber server (HSS). The embodiment of the present disclosure does not limit the implementation form of the network management device 13.

The reduced capability (RedCap) UE introduced in 3rd generation partnership project (3GPP) Release 17 (R17) is mainly aimed at medium-speed applications, and the bandwidth of the RedCap UE under FR1 is up to 20 MHz. In the related art, the applicable bandwidth of the RedCap UE is further reduced. A RedCAP UE that further reduces the bandwidth used is called an enhanced RedCap UE.

Therefore, how to allocate resources for the enhanced Redcap UE with narrow bandwidth and realize data communication with a network device is an urgent problem to be solved.

As shown in FIG. 2, the embodiment of the present disclosure provides an information transmission method that can be performed by a base station of a cellular mobile communication system, and the method includes the following step 201.

At step 201, bandwidth capability information reported by a first type of reduced capability UE is received, where the bandwidth capability information is configured to indicate at least a first bandwidth processing capability of the first type of reduced capability UE, the first bandwidth processing capability is less than or equal to a first bandwidth threshold, the first bandwidth threshold is less than a second bandwidth threshold supported by a second type of reduced capability UE, and the first bandwidth processing capability is configured to determine a maximum bandwidth allocated, by the first type of reduced capability UE, to a data channel.

In all embodiments of the present disclosure, the first type of reduced capability UE may report the type of the first type of the first type of reduced capability UE through the bandwidth capability information, so that the base station side can know the first bandwidth processing capability of the first type of reduced capability UE and/or the first bandwidth threshold.

The first type of reduced capability UE may be an enhanced RedCap UE, and the enhanced RedCap UE can be called an eRedCap UE.

The second type of reduced capability UE may be a RedCap UE in 3GPP Release 17 (R17). A bandwidth processing capability of a radio frequency (RF) transceiver and baseband processing module for the second type of reduced capability UE in the FR1 (Sub-6 GHz) frequency band is 20 MHz. In a possible implementation, a maximum bandwidth which the second type of reduced capability UE can support is 20 MHz.

The first type of reduced capability UE may have a lower baseband processing bandwidth and/or a RF processing bandwidth than the second type of reduced capability UE. In this way, the first type of reduced capability UE can save resources and power compared with the second type of reduced capability UE in data communication. In a possible implementation, a bandwidth processing capability (maximum bandwidth) which the second type of reduced capability UE can support is 5 MHz.

The first type of reduced capability UE can transmit the bandwidth capability information to the base station during and/or after accessing the base station. The second type of reduced capability UE can transmit the bandwidth capability information to the base station during and/or after accessing the base station.

The maximum bandwidth that can be allocated to the data channel by the first type of reduced capability UE may include, but is not limited to, the maximum bandwidth that can be allocated to the data channel by the first type of reduced capability UE. Herein, the data channel may include, but is not limited to, a service data channel. The data channel can be used to transmit communication service data. Illustratively, the data channel may include, but is not limited to, a physical downlink shared channel (PDSCH) and/or a physical uplink shared channel (PDSCH).

The maximum bandwidth that the first type of reduced capability UE can allocate to the data channel can be equal to or less than the first bandwidth processing capability. Alternatively, the maximum bandwidth that the first type of reduced capability UE can allocate to the data channel is less than or equal to the first bandwidth threshold. The first bandwidth processing capability may be less than or equal to the first bandwidth threshold.

In an embodiment, the first bandwidth threshold is 5 MHz and the second bandwidth threshold is 20 MHz. For example, the bandwidth capability information may be used to indicate a first bandwidth processing capability of the first type of reduced capability UE; where the first bandwidth processing capability is less than or equal to 5 MHz.

In all embodiments of the present disclosure, the bandwidth capability information may be the bandwidth value itself, a parameter for identifying the bandwidth value, or a parameter that can determine the bandwidth value according to a preset method, which is not limited in the embodiments of the present disclosure. This is not described in the embodiments of the present disclosure.

For example, the first bandwidth processing capability may be specified by a communication protocol. For example, the communication protocol may specify that the first bandwidth processing capability of the first type of first type of reduced capability UE is 5 MHz. That is, the maximum bandwidth that the first type of reduced capability UE can allocate to the data channel is less than or equal to 5 MHz.

The first bandwidth processing capability can be specified by the communication protocol, reported by the UE to the base station, determined by the base station and transmitted to the UE, or agreed by the base station and the UE. For example, the bandwidth capability information transmitted by the first type of reduced capability UE may include an identifier or indicator for indicating the type of that first type of reduced capability UE to allow the network device to determine that the UE transmitting the bandwidth capability information is a first type of reduced capability UE. In a possible implementation, when the network device determines that the UE is the first type of reduced capability UE through the bandwidth capability information transmitted by the UE, the first bandwidth processing capability of the first type of reduced capability UE can be correspondingly determined.

The maximum bandwidth that the first type of reduced capability UE can allocate to the data channel may include, but is not limited to, a bandwidth on which a signal transmission path of a baseband can transmit data, and/or a bandwidth on which a signal processing component (such as a baseband processor) of a baseband can process data.

The base station can allocate resources for the first type of reduced capability UE based on the bandwidth capability information reported by the first type of reduced capability UE. The bandwidth of the data channel resource configured by the base station for the first type of reduced capability UE may be less than or equal to the first bandwidth processing capability.

In this way, the first type of reduced capability UE indicates the first bandwidth processing capability of the first type of reduced capability UE to the base station through the bandwidth capability information, and the base station configures the data channel resource for the first type of reduced capability UE. Therefore, the first type of reduced capability UE can perform service data processing with relatively small bandwidth processing capability compared with other types of UE, thus reducing workload and further saving power.

The received maximum bandwidth of the first type of reduced capability UE may be a maximum bandwidth for the first type of reduced capability UE to receive the RF signal. The transmitted maximum bandwidth of the first type of reduced capability UE may be a maximum bandwidth for the first type of reduced capability UE to transmit the RF signal.

The maximum bandwidth received and/or transmitted by the first type of reduced capability UE may be less than or equal to the second bandwidth processing capability. In some possible implementations of the present disclosure, the second bandwidth processing capability may be the sum of the maximum bandwidth for transmitting service data and the maximum bandwidth for transmitting control signaling.

The maximum bandwidth received and/or transmitted by the first type of reduced capability UE may include: a maximum bandwidth for the RF processing unit (such as a transceiver antenna, a RF processor, and the like) to transmit and/or receive RF signals.

The maximum bandwidth received and/or transmitted by the first type of reduced capability UE may include: a maximum bandwidth for RF signals that the first type of reduced capability UE can monitor, and/or a maximum bandwidth for RF signals that the first type of reduced capability UE can receive, and/or a maximum bandwidth for RF signals that the first type of reduced capability UE can transmit.

In an embodiment, the third bandwidth threshold is greater than or equal to the first bandwidth threshold.

In an embodiment, the third bandwidth threshold is equal to or less than the second bandwidth threshold.

In all embodiments of the present disclosure, the bandwidth threshold of the first type of reduced capability UE may be further defined as a third bandwidth threshold less than the first bandwidth threshold (5 MHz), so as to further determine that the bandwidth processing capability of the first type of reduced capability UE is less than the first bandwidth threshold. The scenario may be used to further limit the bandwidth capability of the first type of reduced capability UE.

Alternatively, in all embodiments of the present disclosure, a bandwidth threshold of the first type of reduced capability UE may be determined to be a third bandwidth threshold that is greater than the first bandwidth threshold (5 MHz) and less than or equal to a second bandwidth threshold (20 MHz) to limit that the bandwidth processing capability of the first type of reduced capability UE may be greater than the first bandwidth threshold and less than or equal to the second bandwidth threshold. That is, in a possible implementation, it may be determined that the bandwidth capability of the first type of reduced capability UE is greater than 5 MHz and less than or equal to 20 MHz.

The maximum bandwidth received and/or transmitted by the first type of reduced capability UE may be less than or equal to a second bandwidth threshold supported by the second type of reduced capability UE and greater than or equal to the first bandwidth threshold. In this way, the bandwidth capability of the first type of reduced capability UE for receiving and/or transmitting can meet the needs of the first type of reduced capability UE for transmission. For example, the bandwidth capability meets the transmission requirements of data channels, control channels, reference signals, and/or SSBs for the first type of reduced capability UE for transmission. The bandwidth capability information may indicate that the first bandwidth processing capability is less than or equal to the first bandwidth threshold and that the second bandwidth processing capability is less than or equal to the third bandwidth threshold. For example, the bandwidth capability information may indicate that the first bandwidth processing capability is 3 MHz and the second bandwidth processing capability is 10 MHz. Alternatively, the bandwidth capability information may indicate that the first bandwidth processing capability is 5 MHz and the second bandwidth processing capability is 20 MHz.

The third bandwidth processing capability is less than or equal to the first bandwidth threshold, or the third bandwidth processing capability is greater than the first bandwidth threshold and less than or equal to a third bandwidth threshold; and the third bandwidth processing capability is configured to determine a maximum bandwidth allocated, by the first type of reduced capability UE, to a control channel. In all embodiments of the present disclosure, for example, the third bandwidth processing capability may be the maximum bandwidth that the first type of reduced capability UE can allocate to the control channel.

The fourth bandwidth processing capability is less than or equal to the first bandwidth threshold, or the fourth bandwidth processing capability is greater than the first bandwidth threshold and less than or equal to the third bandwidth threshold; and the fourth bandwidth processing capability is configured to determine a maximum bandwidth allocated, by the first type of reduced capability UE, to a reference signal. In all embodiments of the present disclosure, for example, the fourth bandwidth processing capability may be the maximum bandwidth that the first type of reduced capability UE can allocate to the reference signal.

In all embodiments of the present disclosure, the bandwidth capability information can be used to indicate at least one of the following: a first bandwidth processing capability of a first type of reduced capability UE, a second bandwidth processing capability of a second type of reduced capability UE a third bandwidth processing capability of a third type of reduced capability UE, a fourth bandwidth processing capability of a fourth type of reduced capability UE, and a fifth bandwidth processing capability of a fifth type of reduced capability UE.

For example, in a scenario, the first type of reduced capability UE may indicate the second bandwidth processing capability through the bandwidth capability information, so that the network device can know the sum of the maximum bandwidth for transmitting service data and the maximum bandwidth for transmitting control signaling of the first type of reduced capability UE. The first type of reduced capability UE may also indicate a second bandwidth processing capability through the bandwidth capability information, such that the network device can learn the maximum bandwidth for transmitting service data of the first type of reduced capability UE. The network device can determine the maximum bandwidth for transmitting control signaling of the first type of reduced capability UE according to the first bandwidth processing capability and the second bandwidth processing capability.

The maximum bandwidth that the first type of reduced capability UE can allocate to the transmission control channel may be less than or equal to the third bandwidth processing capability. For example, the first bandwidth threshold is 5 MHz, the third bandwidth processing capability may be equal to 5 MHz, and the maximum bandwidth that the UE can allocate to the control channel may be 5 MHz.

The maximum bandwidth that the first type of reduced capability UE can allocate to the transmission reference signal may be less than or equal to the fourth bandwidth processing capability. For example, the first bandwidth threshold is 5 MHz, the fourth bandwidth processing capability may be equal to 5 MHz, and the maximum bandwidth that the UE can allocate to the reference signal may be 5 MHz.

The maximum bandwidth that the first type of reduced capability UE can allocate to the transmission SSB may be less than or equal to the fifth bandwidth processing capability. For example, the first bandwidth threshold is 5 MHz, the fifth bandwidth processing capability may be equal to 5 MHz, and the maximum bandwidth that the UE can allocate to the SSB may be 5MHz.

The control channel may be used to transmit communication control signaling. For example, the control channel may include, but is not limited to, a physical downlink control channel (PDCCH), a physical uplink control channel (PUCCH), and/or a physical random access channel (PRACH). The maximum bandwidth that the first type of reduced capability UE can allocate to the control channel may be: the maximum bandwidth of the first type of reduced capability UE for the control signals transmitted by using the control channel resource.

The reference signal may, but is not limited to, be available to the UE for the channel measurement and/or synchronization. For example, the reference signal may include, but is not limited to, a channel state information-reference signal (CSI-RS), a positioning reference signal (PRS), and/or a sounding reference signal (SRS). For example, the communication protocol may specify the maximum processing bandwidth of the baseband of the UE for the different channels and/or signals.

The range of maximum processing bandwidths specified by the communication protocol for the different channels and/or signals may be the same.

For example, the communication protocol may specify that the maximum bandwidth that the first type of reduced capability UE can allocate to each of: the data channel, the control channel, the reference signal, and the SSB is less than or equal to the first bandwidth threshold. For example, the first bandwidth threshold is 5 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of reduced capability UE can allocate to each of: the data channel, the control channel, the reference signal, and the SSB is less than 5 MHz.

The range of maximum processing bandwidths specified by the communication protocol for the different channels and/or signals may be different. For example, different processing bandwidths can be set for different business scenarios.

For example, in a configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the data channel, the control channel, and the reference signal is less than or equal to the first bandwidth threshold, and that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the SSB is greater than the first bandwidth threshold, and less than or equal to the third bandwidth threshold. For example, the first bandwidth threshold is 5 MHz, and the third bandwidth threshold is 20 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of reduced capability UE can allocate to each of: the data channel and the control channel is less than 5 MHz, and the maximum processing bandwidth that the first type of reduced capability UE can allocate to the SSB is greater than 5 MHz, and less than or equal to 20 MHz.

For example, in a configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the data channel is less than or equal to the first bandwidth threshold, and that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the control channel, and the reference signal, and/or the SSB is greater than the first bandwidth threshold, and less than or equal to the third bandwidth threshold. For example, the first bandwidth threshold is 5 MHz, and the third bandwidth threshold is 20 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the data channel is less than 5 MHz, and the maximum processing bandwidth that the first type of reduced capability UE can allocate to each of: the control channel and the SSB is greater than 5 MHz, and less than or equal to 20 MHz.

The foregoing examples describes several specific configurations, for the data channel, the control channel, the reference signal, and the SSB, configured by the first type of reduced capability UE. Configuration combinations that meet the above-mentioned maximum bandwidth ranges that can be allocated to the data channel, the control channel, the reference signal, and the SSB by the first type of UE can all be considered as implementations configured by the first type of reduced capability UE.

As shown in FIG. 3, the embodiment of the present disclosure provides an information transmission method that can be performed by a base station of a cellular mobile communication system, and the method includes the following steps 301 and 302.

At step 301, a transmission resource for the first type of reduced capability UE is configured based on the bandwidth capability information.

At step 302, resource configuration information indicating the transmission resource is transmitted to the first type of reduced capability UE.

Steps 301 and 302 can be implemented separately or in combination with step 201.

The base station can allocate resources for the first type of reduced capability UE based on the bandwidth capability information. The bandwidth of resource configured by the base station for the first type of reduced capability UE may be less than or equal to the bandwidth processing capability of the first type of reduced capability UE. Herein, the bandwidth processing capability may include the first bandwidth processing capability to the fifth bandwidth processing capability.

The resource configuration information may also be predefined by the communication protocol. The resource configuration information can be stored in the storage of the UE. For example, the transmission resource of the SSB may be predefined, and the first type of reduced capability UE may determine the transmission resource for the SSB based on the predefined resource configuration information.

In this way, the transmission resource is configured within the processing bandwidth indicated by the bandwidth capability information, which meets the bandwidth processing capability of the first type of reduced capability UE. On the one hand, the first type of reduced capability UE uses a relatively small bandwidth in transmission to save transmission resources. On the other hand, the first type of reduced capability UE is allowed to perform service data processing with less bandwidth, thus the workload is reduced and the power is saved.

A maximum bandwidth of the frequency spectrum resource of the data channel is less than or equal to the first bandwidth threshold.

The resource configuration information can be used to schedule frequency spectrum resources, time domain resources, code domain resources, etc.

Different types of frequency spectrum resources can be scheduled with different resource configuration information. For example, the resource configuration information for scheduling the frequency spectrum resource of the data channel may be different from the resource configuration information for scheduling the frequency spectrum resource of the control channel. The resource configuration information can also be used to schedule frequency spectrum resources of different channels and/or signals at the same time. For example, the resource configuration information can be used to schedule both the frequency spectrum resource of the data channel and the frequency spectrum resource of the control channel.

The base station may configure frequency spectrum resources for different channels and/or signals for the first type of reduced capability UE based on the bandwidth processing capability of the first type of reduced capability UE. Reasonable combinations of the bandwidth of the frequency spectrum resource of the data channel, the bandwidth of the frequency spectrum resource of the control channel, the bandwidth of the frequency spectrum resource of the reference signal, and the bandwidth of the frequency spectrum resource of the SSB that meet the bandwidth processing capability of the first type of reduced capability UE can all be used as implementations of the base station to configure the frequency spectrum resources for the first type of reduced capability UE.

For example, for the data channel, the maximum bandwidth that the first type of reduced capability UE can allocate to the data channel may be less than or equal to the first bandwidth threshold. When the base station determines the maximum bandwidth that can be allocated to the first type of reduced capability UE, the bandwidth of the frequency spectrum resource of the data channel can be configured for the first type of reduced capability UE to be less than or equal to the first bandwidth threshold. Therefore, the maximum processing bandwidth of the first type of reduced capability UE is conformed.

For example, in a configuration, the maximum bandwidths that the first type of reduced capability UE can respectively allocate to the data channel, the control channel, the reference signal, and the SSB are all less than or equal to the first bandwidth threshold.

For this configuration, the base station may configure the bandwidth of the frequency spectrum resource of the data channel, the bandwidth of the frequency spectrum resource of the control channel, the bandwidth of the frequency spectrum resource of the reference signal, and the bandwidth of the frequency spectrum resource of the SSB to be less than or equal to the first bandwidth threshold. In this way, the baseband of the first type of reduced capability UE can process the data channel, the control channel, the reference signal and the SSB.

For example, as shown in FIG. 4, the first bandwidth threshold is 5 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of reduced capability UE can allocate to each of: the data channel, the control channel, the reference signal, and the SSB is less than 5 MHz. The base station may configure the bandwidth of the frequency spectrum resource of the data channel, the bandwidth of the frequency spectrum resource of the control channel, the bandwidth of the frequency spectrum resource of the reference signal, and the bandwidth of the frequency spectrum resource of the SSB to be less than 5 MHz.

For example, in a configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the data channel, the control channel, and the reference signal is less than or equal to a first bandwidth threshold, and that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the SSB is greater than the first bandwidth threshold, and less than or equal to the third bandwidth threshold.

For this configuration, the base station may configure the bandwidth of the frequency spectrum resource of the data channel, the bandwidth of the frequency spectrum resource of the control channel, and the bandwidth of the frequency spectrum resource of the reference signal to all be less than or equal to the first bandwidth threshold, and configure the bandwidth of the frequency spectrum resource of the SSB to be greater than the first bandwidth threshold, and less than or equal to the third bandwidth threshold. In this way, the baseband of the first type of reduced capability UE can process the data channel, the control channel, the reference signal and the SSB.

For example, as shown in FIG. 5, the first bandwidth threshold is 5 MHz, and the third bandwidth threshold is 20 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of reduced capability UE can allocate to each of: the data channel, the control channel and the reference signal is less than 5 MHz, and the maximum processing bandwidth that the first type of reduced capability UE can allocate to the SSB is greater than 5 MHz, and less than or equal to 20 MHz. The base station may configure the bandwidth of the frequency spectrum resource of the data channel, the bandwidth of the frequency spectrum resource of the control channel, the bandwidth of the frequency spectrum resource of the reference signal to all be less than 5 MHz, and configure the bandwidth of the frequency spectrum resource of the SSB to be greater than 5 MHz, and less than or equal to 20 MHz.

For this configuration, the base station may configure the bandwidth of the frequency spectrum resource of the data channel to be less than or equal to the first bandwidth threshold, and configure the bandwidth of the frequency spectrum resource of the control channel, the bandwidth of the frequency spectrum resource of the reference signal, and the bandwidth of the frequency spectrum resource of the SSB to be greater than the first bandwidth threshold, and less than or equal to the third bandwidth threshold. In this way, the baseband of the first type of reduced capability UE can process the data channel, the control channel, the reference signal and the SSB.

For example, as shown in FIG. 6, the first bandwidth threshold is 5 MHz, and the third bandwidth threshold is 20 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the data channel is less than 5 MHz, and the maximum processing bandwidth that the first type of reduced capability UE can allocate to each of: the control channel, the reference signal, and the SSB is greater than 5 MHz, and less than or equal to 20 MHz. The base station may configure the bandwidth of the frequency spectrum resource of the data channel to be less than or equal to 5 MHz, and configure the bandwidth of the frequency spectrum resource of the control channel, the bandwidth of the frequency spectrum resource of the reference signal, and the bandwidth of the frequency spectrum resource of the SSB to be greater than 5 MHz, and less than or equal to 20 MHz.

The second bandwidth processing capability of the first type of reduced capability UE is less than or equal to the third bandwidth threshold, i.e., in the bandwidth of the RF frequency domain resource, the first type of reduced capability UE can at most process a bandwidth that is less than or equal to the third bandwidth threshold.

Therefore, the base station, when configuring the frequency spectrum resource of the data channel, the frequency spectrum resource of the control channel, the frequency spectrum resource of the reference signal, and/or the frequency spectrum resource of the SSB for the first type of reduced capability UE, at the same moment, the frequency spectrum resource occupies a span of bandwidth in the frequency domain which is less than or equal to the third bandwidth threshold.

The span of bandwidth is determined based on the lowest frequency resource and the highest frequency resource of at least one of: the frequency spectrum resource of the data channel, the frequency spectrum resource of the control channel, the frequency spectrum resource of the reference signal, or the frequency spectrum resource of the SSB.

For example, a difference between the lowest frequency and the highest frequency occupied by any number (e.g., two or more) of simultaneously monitored signals and/or channels configured by the base station to the first type of reduced capability UE is less than or equal to the third bandwidth threshold. Herein, the signals may include SSBs and/or reference signals, and the channels may include data channels, control channels and/or reference signals.

The RF capability of the first type of reduced capability UE can be specified by a communication protocol, etc. The RF capability may be a second bandwidth processing capability.

For example, the communication protocol may specify that the second bandwidth processing capability of the first type of reduced capability UE is less than or equal to the third bandwidth threshold, i.e., the maximum channel bandwidth of the radio frequency of the first type of reduced capability UE is less than or equal to the third bandwidth threshold.

When the base station configures the BWP for the first type of reduced capability UE, the base station may configure the BWP to be less than or equal to the third bandwidth threshold. In this way, the RF capability of the first type of reduced capability UE can be met.

As shown in FIG. 7, the embodiment of the present disclosure provides an information transmission method that can be performed by a first type of reduced capability UE of a cellular mobile communication system, and the method includes the following step 701.

At step 701, bandwidth capability information is reported to a base station, where the bandwidth capability information is configured to indicate at least a first bandwidth processing capability of the first type of reduced capability UE, the first bandwidth processing capability is less than or equal to a first bandwidth threshold, the first bandwidth threshold is less than a second bandwidth threshold supported by a second type of reduced capability UE, and the first bandwidth processing capability is configured to determine a maximum bandwidth allocated, by the first type of reduced capability UE, to a data channel.

It will be noted that the definition of the same parameters can be the same in the method of the base station and the method of the UE, which are not repeated here.

The first type of reduced capability UE may be an enhanced RedCap UE, and the enhanced RedCap UE can be called an eRedCap UE.

The second type of reduced capability UE may be a RedCap UE in 3GPP Release 17 (R17). The bandwidth processing capability of the radio frequency (RF) transceiver and baseband processing module for the second type of reduced capability UE in the FR1 (Sub-6 GHz) frequency band is 20 MHz. In a possible implementation, a maximum bandwidth which the second type of reduced capability UE can support is 20 MHz.

The first type of reduced capability UE may have a lower baseband processing bandwidth and/or RF processing bandwidth than the second type of reduced capability UE. In this way, the first type of reduced capability UE can save resources and power compared with the second type of reduced capability UE in data communication. In a possible implementation, a bandwidth processing capability (maximum bandwidth) which the second type of reduced capability UE can support is 5 MHz.

The maximum bandwidth that can be allocated to the data channel by the first type of reduced capability UE may include, but is not limited to, the maximum bandwidth that can be allocated to the data channel by the first type of reduced capability UE. Herein, the data channel may include, but is not limited to, a service data channel. The data channel can be used to transmit communication service data. For example, the data channel may include, but is not limited to, a PDSCH and/or a PUSCH.

The maximum bandwidth that the first type of reduced capability UE can allocate to the data channel can be equal to or less than the first bandwidth processing capability. Alternatively, the maximum bandwidth that the first type of reduced capability UE can allocate to the data transmission is less than or equal to the first bandwidth threshold. The first bandwidth processing capability may be less than or equal to the first bandwidth threshold.

The received maximum bandwidth of the first type of reduced capability UE may be a maximum bandwidth on which the first type of reduced capability UE receives the RF signal. The transmitted maximum bandwidth of the first type of reduced capability UE may be a maximum bandwidth on which the first type of reduced capability UE transmits the RF signal.

In an embodiment, the third bandwidth threshold is greater than or equal to the first bandwidth threshold.

In an embodiment, the third bandwidth threshold is equal to or less than the second bandwidth threshold.

In all embodiments of the present disclosure, the bandwidth threshold of the first type of reduced capability UE may be further defined as a third bandwidth threshold less than the first bandwidth threshold (5 MHz), so as to further determine that the bandwidth processing capability of the first type of reduced capability UE is less than the first bandwidth threshold. The scenario exemplarily may be used to further limit the bandwidth capability of the first type of reduced capability UE.

The bandwidth capability information may indicate that the first bandwidth processing capability is less than or equal to the first bandwidth threshold and that the second bandwidth processing capability is less than or equal to the third bandwidth threshold. For example, the bandwidth capability information may indicate that the first bandwidth processing capability is 3 MHz and the second bandwidth processing capability is 10 MHz. Alternatively, the bandwidth capability information may indicate that the first bandwidth processing capability is 5 MHz and the second bandwidth processing capability is 20 MHz.

The third bandwidth processing capability is less than or equal to the first bandwidth threshold, or the third bandwidth processing capability is greater than the first bandwidth threshold and less than or equal to a third bandwidth threshold; and the third bandwidth processing capability is configured to determine a maximum bandwidth allocated, by the first type of reduced capability UE, to a control channel; In all embodiments of the present disclosure, for example, the third bandwidth processing capability may be the maximum bandwidth that the first type of reduced capability UE can allocate to the control channel.

The fourth bandwidth processing capability is less than or equal to the first bandwidth threshold, or the fourth bandwidth processing capability is greater than the first bandwidth threshold and less than or equal to the third bandwidth threshold; and the fourth bandwidth processing capability is configured to determine a maximum bandwidth allocated, by the first type of reduced capability UE, to a reference signal. In all embodiments of the present disclosure, for example, the third bandwidth processing capability may be the maximum bandwidth that the first type of reduced capability UE can allocate to the reference signal.

The control channel may be used to transmit communication control signaling. For example, the control channel may include, but is not limited to, a PDCCH, a PUCCH, and/or a PRACH. The maximum bandwidth that the first type of reduced capability UE can allocate to the control channel may be: the maximum bandwidth of the first type of reduced capability UE for the control signals transmitted by using the control channel resource.

The reference signal can be used to transmit reference signaling. The reference signal may, but is not limited to, be available to the UE for the channel measurement and/or synchronization. For example, the reference signal may include, but is not limited to, a CSI-RS, a PRS, and/or an SRS. For example, the communication protocol may specify the maximum processing bandwidth of the baseband of the UE for the different channels and/or signals.

The range of maximum processing bandwidths specified by the communication protocol for the different channels and/or signals may be the same.

For example, the communication protocol may specify at least one of maximum bandwidths that the first type of reduced capability UE can allocate to the data channel, the control channel, the reference signal, and the SSB, respectively, and the maximum bandwidth that the first type of reduced capability UE can allocate to each of: the data channel, the control channel, the reference signal, and the SSB is less than or equal to the first bandwidth threshold. For example, the first bandwidth threshold is 5 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of reduced capability UE can allocate to each of: the data channel, the control channel, the reference signal, and the SSB is less than 5 MHz.

For example, in a configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the data channel, the control channel, and the reference signal is less than or equal to a first bandwidth threshold, and that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the SSB is greater than the first bandwidth threshold, and less than or equal to the third bandwidth threshold. For example, the first bandwidth threshold is 5 MHz, and the third bandwidth threshold is 20 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of reduced capability UE can allocate to each of: the data channel and the control channel is less than 5 MHz, and the maximum processing bandwidth that the first type of reduced capability UE can allocate to the SSB is greater than 5MHz, and less than or equal to 20 MHz.

For example, in a configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the data channel is less than or equal to the first bandwidth threshold, and that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the control channel, and the reference signal, and/or the SSB is greater than the first bandwidth threshold, and less than or equal to the third bandwidth threshold. For example, the first bandwidth threshold is 5 MHz, and the third bandwidth threshold is 20 MHz. The bandwidth capability information may indicate that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the data channel is less than 5 MHz, and the maximum processing bandwidth that the first type of reduced capability UE can allocate to each of: the control channel and the SSB is greater than 5 MHz, and less than or equal to 20 MHz.

The foregoing examples describes several specific configurations, for the data channel, the control channel, the reference signal, and the SSB, configured by the first type of reduced capability UE. Configuration combinations that meet the above-mentioned maximum bandwidth ranges that can be allocated to each of: the data channel, the control channel, the reference signal, and the SSB by the first type of UE can be considered as implementations configured by the first type of reduced capability UE.

As shown in FIG. 8, the embodiment of the present disclosure provides an information transmission method that can be performed by a first type of reduced capability UE of a cellular mobile communication system, and the method includes the following step 801a and/or step 801b.

At step 801a, resource configuration information from the base station is received, where the resource configuration information is configured to indicate a transmission resource for the first type of reduced capability UE, and the resource configuration information is determined by the base station based on the bandwidth capability information.

At step 801b, predefined resource configuration information is obtained.

The steps 801a and 801b can be implemented separately or in combination with step 701.

The resource configuration information may also be predefined by the communication protocol. The resource configuration information can be stored in the storage of the UE. For example, the transmission resources of the SSB may be predefined, and the first type of reduced capability UE may determine the transmission resource for the SSB based on the predefined resource configuration information.

In this way, the transmission resource is configured within the processing bandwidth indicated by the bandwidth capability information, which meets the bandwidth processing capability of the first type of reduced capability UE. On the one hand, the first type of UE uses a relatively small bandwidth in transmission to save transmission resources. On the other hand, the first type of reduced capability UE is allowed to perform service data processing with less bandwidth, thus the workload is reduced and the power is saved.

A maximum bandwidth of the frequency spectrum resource of the data channel is less than or equal to the first bandwidth threshold.

The resource configuration information can be used to schedule frequency spectrum resources, time domain resources, code domain resources, etc.

For example, in a configuration, the maximum bandwidth that the first type of reduced capability UE can allocate to each of: the data channel, the control channel, the reference signal, and the SSB is less than or equal to the first bandwidth threshold.

For example, in a configuration, the bandwidth capability information indicates that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the data channel, the control channel, and the reference signal is less than or equal to a first bandwidth threshold, and that the maximum processing bandwidth that the first type of reduced capability UE can allocate to the SSB is greater than the first bandwidth threshold, and less than or equal to the third bandwidth threshold.

For this configuration, the base station may configure the bandwidth of the frequency spectrum resource of the data channel, the bandwidth of the frequency spectrum resource of the control channel, and the bandwidth of the frequency spectrum resource of the reference signal to all be less than or equal to the first bandwidth threshold, and configure the bandwidth of the frequency spectrum resource of the SSB to be greater than the first bandwidth threshold, and less than or equal to the third bandwidth threshold. In this way, the baseband of the first type of reduced capability UE can process the data channel, the control channel, the reference signal and the SSB.

Therefore, the base station, when configuring the frequency spectrum resource of the data channel, the frequency spectrum resource of the control channel, the frequency spectrum resource of the reference signal, and/or the frequency spectrum resource of the SSB for the first type of reduced capability UE, at the same moment, the frequency spectrum resource occupies a span of bandwidths in the frequency domain which is less than or equal to the third bandwidth threshold.

The RF capability of the first type of reduced capability UE can be specified by a communication protocol, etc. The RF capability may be a second bandwidth processing capability.

A specific example is provided below in connection with any of the embodiments.

In the related art, it is required to further reduce the bandwidth of the UE on the basis of the FR1 RedCap UE to obtain an eRedCap UE. However, reducing the RF bandwidth and the baseband bandwidth at the same time will bring great changes to the protocol and affect the realization of the product.
