Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, device, and readable storage medium for transmitting capability information or configuration information. Background Art

[0002] In related technologies, the guard band is determined based on the difference between the channel bandwidth and the transmission bandwidth. Consequently, the minimum guard band for a 30MHz CBW may be larger than the minimum guard band for a 40MHz CBW. When a user device (UE) accesses a 40MHz system bandwidth with a 30MHz channel bandwidth in the N28 band, and the carrier edge extends beyond the lower bandwidth limit (758MHz), the UE loses network access due to a Radio Resource Control (RRC) reconfiguration failure.

[0081] The embodiments of the present disclosure are now further described with reference to the accompanying drawings and specific implementation methods.

[0085] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0086] like Figure 1 As shown, a method for transmitting capability information or configuration information provided in an embodiment of the present disclosure may be applied to a wireless communication system 100, which may include but is not limited to a network device 101 and a user device 102. The user device 102 is configured to support carrier aggregation, and the user device 102 may be connected to multiple carrier components of the network device 101, including a primary carrier component and one or more secondary carrier components.

[0087] It should be understood that the above wireless communication system 100 is applicable to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems.

[0088] The user equipment 102 shown above may be user equipment (UE), terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication device, terminal agent or user equipment, etc. The user equipment 102 may have wireless transceiver functions, and may communicate (e.g., wirelessly) with one or more network devices 101 of one or more communication systems and receive network services provided by the network devices 101. The network devices 101 herein include but are not limited to the base stations shown in the figure.

[0089] Among them, the user equipment 102 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a user device in a future 5G network, or a user device in a future evolved PLMN network, etc.

[0090] The network device 101 may be an access network device (or access network node). The access network device refers to a device that provides network access functions, such as a radio access network (RAN) base station, etc. The network device may specifically include a base station (BS) device, or a base station device and a radio resource management device for controlling the base station device, etc. The network device may also include a relay station (relay device), an access point, a base station in a future 5G network, a base station in a future evolved PLMN network, or an NR base station, etc. The network device may be a wearable device or an in-vehicle device. The network device may also be a communication chip with a communication module.

[0091] For example, the network device 101 includes but is not limited to: the next generation base station (gnodeB, gNB) in 5G, the evolved node B (eNB) in the LTE system, the radio network controller (RNC), the node B (NB) in the WCDMA system, the wireless controller under the CRAN system, the base station controller (BSC), the base transceiver station (BTS) in the GSM system or the CDMA system, the home base station (for example, home evolved nodeB, or home nodeB, HNB), the baseband unit (BBU), the transmission point (TRP), the transmitting point (TP) or the mobile switching center, etc.

[0092] User equipment has the following two RF implementation methods for frequency band n28:

[0093] The first is to cover the entire n28 45MHz spectrum through a wide duplexer.

[0094] The second method uses two 30MHz duplexers to cover the n28 45MHz spectrum.

[0095] The user equipment side supports a maximum channel bandwidth of 30MHz, and the gNB supports a maximum channel bandwidth of 40MHz.

[0096] In actual network deployment, gNB uses a 40MHz constant bandwidth (CBW). Considering the UE's capabilities, a dedicated 30MHz fixed bandwidth can be used. The dedicated 30MHz bandwidth is limited to 703-733 / 758-788 or 718-748 / 768-798MHz. In one example, the starting point of the RB of the UE and the starting point of the RB of the gNB can be aligned. Figure 6 As shown in . The low-frequency and high-frequency protection bandwidths of the network-side channel bandwidth are identical, both 552.5 kHz. The low-frequency and high-frequency protection bandwidths of the user-side channel bandwidth are identical, both 592.5 kHz. The carrier frequency center of the network-side channel bandwidth includes a 15 kHz free space, and the carrier frequency center of the user-side channel bandwidth also includes a 15 kHz free space.

[0097] In some implementations, the low-band guard bandwidth and the high-band guard bandwidth of the same channel bandwidth are the same, and the guard band is determined based on the difference between the channel bandwidth and the transmission bandwidth, for example:

[0098] When the subcarrier spacing (SCS) is 15 kHz, the maximum transmission bandwidth of the gNB's 40 MHz CBW is configured as 216 PRBs, and the minimum guard band is 552.5 kHz.

[0099] When the subcarrier spacing (SCS) is 15 kHz, the maximum transmission bandwidth of the UE's 30 MHz CBW is configured as 160 PRBs, and the minimum guard band is 592.5 kHz.

[0100] Therefore, there occurs a situation where the minimum guard band of the 30 MHz CBW is larger than the minimum guard band of the 40 MHz CBW.

[0101] In view of this, an embodiment of the present disclosure provides a method for transmitting user equipment capability information. Figure 2 FIG. 1 is a flow chart showing a method for transmitting user equipment capability information according to an exemplary embodiment. Figure 2 As shown, the method includes steps S201-S203:

[0102] Step S201: User equipment sends user equipment capability information to a network device.

[0103] The user equipment capability information is used to indicate whether a first capability is supported, where the first capability is that the user equipment side channel bandwidth supports a first protection bandwidth and a second protection bandwidth at the same time, and the first protection bandwidth is greater than the second protection bandwidth.

[0104] In some possible implementations, the method for a user device to send user device capability information to a network device is: sending user device capability information including radio frequency parameters to the network device, the radio frequency parameters including an information field for indicating whether authorization-based narrow guard band bandwidth transmission (supportednarrowGB) is supported, and the information field is used to indicate whether the first capability is supported.

[0105] In some possible implementations, the second protection bandwidth is equal to the minimum protection bandwidth of the network side channel bandwidth, and the user equipment side channel bandwidth is smaller than the network side channel bandwidth.

[0106] In some possible implementations, the first guard bandwidth and the second guard bandwidth are low-frequency guard bandwidths of the user equipment side channel bandwidth.

[0107] In step S202, the network device sends configuration information to the user equipment, where the configuration information is used to indicate the starting position of the first physical resource block corresponding to the network side channel bandwidth in the set frequency band.

[0108] In step S203, the user equipment determines whether the interval between the starting position of the first physical resource block and the low-frequency starting position of the set frequency band is greater than or equal to the minimum supported protection bandwidth. If so, it is determined that the access condition is met; if not, it is determined that the access condition is not met.

[0109] The following is an example to illustrate:

[0110] This example applies to the downlink frequency band from 758 MHz to 788 MHz in band n28.

[0111] When the SCS is 15 kHz, the user equipment side channel bandwidth is 30 MHz, the maximum transmission bandwidth is configured as 160 PRBs, and the first protection bandwidth is 592.5 kHz. The network side channel bandwidth is 40 MHz, the maximum transmission bandwidth is configured as 216 PRBs, and the minimum protection bandwidth is 552.5 kHz.

[0112] The UE supports the first capability, specifically: supports the first protection bandwidth and the second protection bandwidth, that is, supports the first protection bandwidth of 592.5 KHz and also supports the second protection bandwidth of 552.5 KHz.

[0113] The user equipment sends user equipment capability information to the network device, where the user equipment capability information indicates support for a first capability.

[0114] The network device sends configuration information to the user equipment, indicating that the starting position of the first physical resource block corresponding to the network side channel bandwidth in the set frequency band is 758MHz+552.5Khz.

[0115] The user equipment determines that the interval between the starting position of the first physical resource block and the low-frequency starting position of the set frequency band is 552.5Khz, and determines that this interval is equal to the minimum protection bandwidth it supports, namely the second protection bandwidth 552.5KHz, thereby determining that the access conditions are met.

[0116] In an embodiment of the present disclosure, a user device reports user device capability information to a network device to indicate that the user device can support a larger protection bandwidth while also supporting another smaller protection bandwidth in the user device side channel bandwidth, thereby eliminating the dependence of the protection bandwidth on the difference between the channel bandwidth and the transmission bandwidth, thereby avoiding a situation where the user device fails to access the network due to the protection bandwidth of the user device side channel bandwidth being greater than the protection bandwidth of the network side channel bandwidth when the user device accesses the network within a set frequency band.

[0117] The embodiment of the present disclosure provides a method for sending user equipment capability information, which is executed by the user equipment. Figure 3 FIG. 1 is a flow chart showing a method for sending user equipment capability information according to an exemplary embodiment. Figure 3 As shown, the method includes steps S301-S303:

[0118] Step S301: Send user equipment capability information to a network device.

[0119] The user equipment capability information is used to indicate whether a first capability is supported, where the first capability is that the user equipment side channel bandwidth supports a first protection bandwidth and a second protection bandwidth at the same time, and the first protection bandwidth is greater than the second protection bandwidth.

[0120] In some possible implementations, the method for a user device to send user device capability information to a network device is: sending user device capability information including radio frequency parameters to the network device, the radio frequency parameters including an information field for indicating whether authorization-based narrow guard band bandwidth transmission (supported narrow GB) is supported, and the information field is used to indicate whether the first capability is supported.

[0121] In some possible implementations, the second protection bandwidth is equal to the minimum protection bandwidth of the network side channel bandwidth, and the user equipment side channel bandwidth is smaller than the network side channel bandwidth.

[0122] In some possible implementations, the first guard bandwidth and the second guard bandwidth are low-frequency guard bandwidths of the user equipment side channel bandwidth.

[0123] Step S302: receiving configuration information sent by a network device, where the configuration information is used to indicate a starting position of a first physical resource block corresponding to a network side channel bandwidth within a set frequency band.

[0124] Step S303, determine whether the interval between the starting position of the first physical resource block and the low-frequency starting position of the set frequency band is greater than or equal to the minimum supported protection bandwidth. If so, determine that the access condition is met; if not, determine that the access condition is not met.

[0125] The embodiment of the present disclosure provides a method for receiving user equipment capability information, which is executed by a network device. Figure 4 FIG. 1 is a flow chart showing a method for receiving user equipment capability information according to an exemplary embodiment. Figure 4 As shown, the method includes steps S401-S402:

[0126] Step S401: receiving user equipment capability information sent by user equipment.

[0127] The user equipment capability information is used to indicate whether a first capability is supported, where the first capability is that the user equipment side channel bandwidth supports a first protection bandwidth and a second protection bandwidth at the same time, and the first protection bandwidth is greater than the second protection bandwidth.

[0128] In some possible implementations, the method for a user device to send user device capability information to a network device is: sending user device capability information including radio frequency parameters to the network device, the radio frequency parameters including an information field for indicating whether authorization-based narrow guard band bandwidth transmission (supported narrow GB) is supported, and the information field is used to indicate whether the first capability is supported.

[0129] In some possible implementations, the second protection bandwidth is equal to the minimum protection bandwidth of the network side channel bandwidth, and the user equipment side channel bandwidth is smaller than the network side channel bandwidth.

[0130] In some possible implementations, the first guard bandwidth and the second guard bandwidth are low-frequency guard bandwidths of the user equipment side channel bandwidth.

[0131] Step S402: Send configuration information to the user equipment, where the configuration information is used to indicate the starting position of the first physical resource block corresponding to the network side channel bandwidth in the set frequency band.

[0132] Given the UE's self-detection behavior in the RRC connection, when it detects that its carrier edge extension exceeds the lower limit of the frequency band to be accessed, for example, when accessing the 40MHz network side channel bandwidth in the frequency band n28, it may stop accessing the network due to RRC reconfiguration failure, and maintain the RRC_CONNECTED state but with degraded performance (especially at the lowest PRB at the carrier edge).

[0133] The present disclosure provides a method for transmitting configuration information. Figure 5 FIG. 1 is a flow chart showing a method for transmitting configuration information according to an exemplary embodiment. Figure 5 As shown, the method includes step S501:

[0134] Step S501: The network device sends first configuration information and second configuration information to the user equipment.

[0135] The first configuration information is used to indicate an offset, where the offset is the offset of the starting position of the low-frequency protection band of the network side channel bandwidth, and the offset direction corresponding to the offset is from low frequency to high frequency;

[0136] The second configuration information is used to indicate the starting position of the first physical resource block corresponding to the network side channel bandwidth in the set frequency band, and the starting position is determined according to the offset.

[0137] In some possible embodiments, the offset is a first value, and the first value is an integer multiple of the granularity of the channel grid.

[0138] For example, if the channel grid granularity is 100kHz, the offset is an integer multiple of 100kHz to ensure that the carrier center is aligned with the channel grid. For example, the offset is 100kHz, 200KHz, 300KHz, etc.

[0139] In one example, if Figure 6 As shown, the frequency band is set to the downlink frequency band of 758MHz to 788MHz in the n28 band, the network side channel band is 40MHz, the low frequency starting position is 758MHz, the low frequency protection band is 552.5kHz, and the offset of the starting position of the low frequency protection band is 100kHz. The starting position of the first physical resource block in the network side channel band is also correspondingly offset by 100kHz toward the high frequency direction. Then, the starting position of the first physical resource block in the network side channel band is 758MHz+552.5kHz+100kHz.

[0140] In some possible embodiments, the network device does not schedule the last at least one physical resource block within the network side channel frequency band.

[0141] For example: when the frequency band is set to the downlink frequency band of 758MHz to 788MHz in the n28 frequency band, the network side channel frequency band is a 40MHz channel bandwidth, the network side channel frequency band includes 216 physical resource blocks, and the offset is 100kHz, the network device does not schedule the last physical resource block during network scheduling.

[0142] In some possible embodiments, the offset is a second value, which is the difference between the protection bandwidth of the user equipment side channel bandwidth and the protection bandwidth of the network side channel bandwidth, the network side channel bandwidth is greater than the user equipment side channel bandwidth, and the protection bandwidth of the network side channel bandwidth is less than the protection bandwidth of the user equipment side channel bandwidth.

[0143] For example: set the frequency band to n28 band, the network side channel band to 40MHz channel bandwidth, the protection bandwidth of the network side channel band to 552.5kHz, the user equipment side channel band to 30MHz channel bandwidth, the protection bandwidth of the user equipment side channel to 592.5kHz, and the difference between the protection bandwidth of the user equipment side channel band and the protection bandwidth of the network side channel band is 40kHz. The offset is 40kHz, so that the low-frequency protection band of the network side channel band is consistent with the low-frequency protection band of the user equipment side channel band after offset.

[0144] Step S502, determine whether the interval between the starting position of the first physical resource block and the low-frequency starting position of the set frequency band is greater than or equal to the minimum supported protection bandwidth. If so, determine that the access condition is met; if not, determine that the access condition is not met.

[0145] In one example: Figure 6 As shown, the frequency band is set to the downlink frequency band of 758MHz to 788MHz in the n28 band, the network side channel band is 40MHz, the low frequency starting position is 758MHz, the low frequency protection band is 552.5kHz, and the offset of the starting position of the low frequency protection band is 100kHz. The starting position of the first physical resource block in the network side channel band is also correspondingly offset by 100kHz toward the high frequency direction. Then, the starting position of the first physical resource block in the network side channel band is 758MHz+552.5kHz+100kHz.

[0146] The user equipment determines that the interval between the starting position of the first physical resource block in the network side channel frequency band and the low frequency starting position of the set frequency band is 652.5kHz, and determines that it is greater than the minimum protection bandwidth supported by the user equipment, namely 592.5kHz, and determines that the access conditions are met.

[0147] In another example, the frequency band is set to the downlink frequency band of 758MHz to 788MHz in the n28 frequency band, the network side channel frequency band is 40MHz, the low frequency starting position is 758MHz, the low frequency protection band is 552.5kHz, and the offset of the starting position of the low frequency protection band is 40kHz. The starting position of the first physical resource block in the network side channel frequency band is also correspondingly offset by 40kHz toward the high frequency direction. Then, the starting position of the first physical resource block in the network side channel frequency band is 758MHz+552.5kHz+40kHz.

[0148] The user equipment determines that the interval between the starting position of the first physical resource block in the network side channel frequency band and the low frequency starting position of the set frequency band is 592.5kHz, and determines that it is equal to the minimum protection bandwidth supported by the user equipment, i.e., 592.5kHz, and determines that the access conditions are met.

[0149] In the embodiment of the present disclosure, by shifting the starting position of the protection band of the network side channel bandwidth and the starting position of the first physical resource block of the network side channel bandwidth toward the high frequency direction, the problem of user equipment access failure or connection performance degradation caused by the protection bandwidth of the user equipment side channel bandwidth being greater than the protection bandwidth of the network side channel bandwidth when the user equipment accesses the network within the set frequency band is avoided.

[0150] The embodiment of the present disclosure provides a method for sending configuration information, which is executed by a network device. Figure 7 FIG. 1 is a flow chart showing a method for sending configuration information according to an exemplary embodiment. Figure 7 As shown, the method includes step S701:

[0151] Step S701: Send first configuration information and second configuration information to user equipment.

[0152] The first configuration information is used to indicate an offset, where the offset is the offset of the starting position of the low-frequency protection band of the network side channel bandwidth, and the offset direction corresponding to the offset is from low frequency to high frequency;

[0153] The second configuration information is used to indicate the starting position of the first physical resource block corresponding to the network side channel bandwidth in the set frequency band, and the starting position is determined according to the offset.

[0154] In some possible embodiments, the offset is a first value, and the first value is an integer multiple of the granularity of the channel grid.

[0155] For example, if the channel grid granularity is 100kHz, the offset is an integer multiple of 100kHz to ensure that the carrier center is aligned with the channel grid. For example, the offset is 100kHz, 200KHz, 300KHz, etc.

[0156] In one example, if Figure 6 As shown, the frequency band is set to the downlink frequency band of 758MHz to 788MHz in the n28 band, the network side channel band is 40MHz, the low frequency starting position is 758MHz, the low frequency protection band is 552.5kHz, and the offset of the starting position of the low frequency protection band is 100kHz. The starting position of the first physical resource block in the network side channel band is also correspondingly offset by 100kHz toward the high frequency direction. Then, the starting position of the first physical resource block in the network side channel band is 758MHz+552.5kHz+100kHz.

[0157] In some possible embodiments, the network device does not schedule the last at least one physical resource block within the network side channel frequency band.

[0158] For example: when the frequency band is set to the downlink frequency band of 758MHz to 788MHz in the n28 frequency band, the network side channel frequency band is a 40MHz channel bandwidth, the network side channel frequency band includes 216 physical resource blocks, and the offset is 100kHz, the network device does not schedule the last physical resource block during network scheduling.

[0159] In some possible embodiments, the offset is a second value, which is the difference between the protection bandwidth of the user equipment side channel bandwidth and the protection bandwidth of the network side channel bandwidth, the network side channel bandwidth is greater than the user equipment side channel bandwidth, and the protection bandwidth of the network side channel bandwidth is less than the protection bandwidth of the user equipment side channel bandwidth.

[0160] For example: set the frequency band to n28 band, the network side channel band to 40MHz channel bandwidth, the protection bandwidth of the network side channel band to 552.5kHz, the user equipment side channel band to 30MHz channel bandwidth, the protection bandwidth of the user equipment side channel to 592.5kHz, and the difference between the protection bandwidth of the user equipment side channel band and the protection bandwidth of the network side channel band is 40kHz. The offset is 40kHz, so that the low-frequency protection band of the network side channel band is consistent with the low-frequency protection band of the user equipment side channel band after offset.

[0161] The present disclosure provides a method for receiving configuration information, which is executed by a user equipment. Figure 8 is a flow chart showing a method for receiving configuration information according to an exemplary embodiment. Figure 8 As shown, the method includes steps S801-S802:

[0162] Step S801: Receive first configuration information and second configuration information sent by a network device.

[0163] The first configuration information is used to indicate an offset, where the offset is the offset of the starting position of the low-frequency protection band of the network side channel bandwidth, and the offset direction corresponding to the offset is from low frequency to high frequency;

[0164] The second configuration information is used to indicate the starting position of the first physical resource block corresponding to the network side channel bandwidth in the set frequency band, and the starting position is determined according to the offset.

[0165] In some possible embodiments, the offset is a first value, and the first value is an integer multiple of the granularity of the channel grid.

[0166] For example, if the channel grid granularity is 100kHz, the offset is an integer multiple of 100kHz to ensure that the carrier center is aligned with the channel grid. For example, the offset is 100kHz, 200KHz, 300KHz, etc.

[0167] In one example, if Figure 6 As shown, the frequency band is set to the downlink frequency band of 758MHz to 788MHz in the n28 band, the network side channel band is 40MHz, the low frequency starting position is 758MHz, the low frequency protection band is 552.5kHz, and the offset of the starting position of the low frequency protection band is 100kHz. The starting position of the first physical resource block in the network side channel band is also correspondingly offset by 100kHz toward the high frequency direction. Then, the starting position of the first physical resource block in the network side channel band is 758MHz+552.5kHz+100kHz.

[0168] In some possible embodiments, the network device does not schedule the last at least one physical resource block within the network side channel frequency band.

[0169] For example: when the frequency band is set to the downlink frequency band of 758MHz to 788MHz in the n28 frequency band, the network side channel frequency band is a 40MHz channel bandwidth, the network side channel frequency band includes 216 physical resource blocks, and the offset is 100kHz, the network device does not schedule the last physical resource block during network scheduling.

[0170] In some possible embodiments, the offset is a second value, which is the difference between the protection bandwidth of the user equipment side channel bandwidth and the protection bandwidth of the network side channel bandwidth, the network side channel bandwidth is greater than the user equipment side channel bandwidth, and the protection bandwidth of the network side channel bandwidth is less than the protection bandwidth of the user equipment side channel bandwidth.

[0171] For example: set the frequency band to n28 band, the network side channel band to 40MHz channel bandwidth, the protection bandwidth of the network side channel band to 552.5kHz, the user equipment side channel band to 30MHz channel bandwidth, the protection bandwidth of the user equipment side channel to 592.5kHz, and the difference between the protection bandwidth of the user equipment side channel band and the protection bandwidth of the network side channel band is 40kHz. The offset is 40kHz, so that the low-frequency protection band of the network side channel band is consistent with the low-frequency protection band of the user equipment side channel band after offset.

[0172] Step S802, determine whether the interval between the starting position of the first physical resource block and the low-frequency starting position of the set frequency band is greater than or equal to the minimum supported protection bandwidth. If so, determine that the access condition is met; if not, determine that the access condition is not met.
