Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a frequency band type indication method, device and apparatus. Background Art

[0002] The R16 (Release 16) protocol discusses two frequency band types for uplink transmission switching: Band A and Band B. Since each of these two band types contains only one component carrier (CC) (i.e., Band A includes carrier 1, and Band B includes carrier 2), user equipment (UE) can report its capabilities by including the band pair information it supports for UL TX switching. This allows the network to indicate to the UE whether the carrier of the cell it resides on is carrier 1 or carrier 2.

[0003] However, in addition to Band A and Band B, future protocols may discuss or define more frequency band types, and the carrier components included in different frequency band types may also vary. If the traditional UL TX Switching terminal capability reporting method is used, the network equipment cannot determine which frequency band type of carrier in UL TX Switching the cell configured for the UE belongs to, resulting in the UE being unable to correctly understand the frequency band type of the cell carrier configured by the network equipment.

The terms "system" and "network" in the embodiments of the present application are often used interchangeably, and the described technology can be used for the systems and radio technologies mentioned above, as well as for other systems and radio technologies. The following description describes the NR system for illustrative purposes, and NR terminology is used in most of the following description, but these technologies can also be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0027] Figure 1The block diagram of a wireless communication system applicable to the embodiments of the present application is shown. The wireless communication system includes a terminal device 11 and a network device 12. The terminal device 11 can be a mobile phone, a tablet personal computer, a laptop computer or a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, a vehicle-mounted equipment (VUE), a pedestrian terminal (PUE), a smart home (home appliances with wireless communication functions, such as refrigerators, televisions, washing machines, or furniture), and other terminal-side devices.

[0028] The network device 12 can be a base station or a core network, where the base station can be called a node B, an evolved node B, an access point, a base transceiver station (BTS), a radio base station, a radio transceiver, a basic service set (BSS), an extended service set (ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting receiving point (TRP) or other appropriate terms in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0029] Currently, R16 discusses two frequency band types for UL TX Switching: band A and band B. Since each of these two frequency band types contains only one CC (i.e., band A contains carrier 1, and band B contains carrier 2), the terminal device can carry the band pair information of the supported UL TX Switching when reporting its capabilities.

[0030] Specifically, the terminal device can use the members bandIndexUL1-r16 and bandIndexUL2-r16 to report the band pairs it supports. Because band B in R16 uses only one CC, the same as band A, the bandIndexUL1-r16 and bandIndexUL2-r16 reported by the terminal device do not need to specifically indicate whether they are band A or band B. Subsequently, the network device can use the uplinkTxSwitchingCarrier-r16 field in the ServingCellConfig information element to indicate to the terminal device whether the cell carrier is carrier 1 or carrier 2.

[0031] In R17, band B can include one or two consecutive carriers, called carrier 2 and carrier 3. The BandCombinationList information element used by terminal devices to report capabilities can reuse the R16 information element. For example, Table 1 shows several scenarios in UL TX Switching discussed in R17:

[0032] Table 1

[0033] Scenario 0 R16 1T-2T switch Band A uses 1 CC, and band B uses 1 CC Scenario 1 R17 1T-2T switch Band A uses 1 CC, band B uses 2 CCs Scenario 2 R17 2T-2T switch Band A uses 1 CC, and band B uses 1 CC Scenario 3 R17 2T-2T switch Band A uses 1 CC, band B uses 2 CCs

[0034] The current solution is sufficient for scenarios with only band A and band B, because UL TX Switching itself implies at least two band types and does not require special indication. For example, in the E-UTRA NR dual connectivity with MCG using E-UTRA and SCG using NR (EN-DC) scenario, the so-called NR carrier is always configured as carrier 2.

[0035] However, in addition to band A and band B, future protocols may discuss or define more frequency band types, and the carrier units included in different frequency band types may also be different. For example, when band A is defined to include one or two non-contiguous CCs, and band B only includes one CC, the enumeration value {carrier1, carrier2, carrier3} of the uplinkTxSwitchingCarrier member of the UplinkTxSwitching field cannot let the terminal device know whether it is "band A uses 1 CC, band B uses 2 CCs" or "band A uses 2 CCs, band B uses 1 CC." Therefore, if the traditional UL TXSwitching terminal capability reporting method is used, the network device cannot determine which frequency band type of carrier in UL TXSwitching the carrier of the cell configured for the terminal device is, resulting in an inability to correctly understand the frequency band type of the cell carrier configured by the network device.

[0036] It should be noted that the embodiment of the present application is illustratively described by taking the frequency band group including two frequency bands as an example, and the frequency band group may also include three or more frequency bands.

[0037] In addition, a frequency band group can also be referred to as a frequency band combination, and the number of frequency bands within a frequency band group can be two or more. When a frequency band group includes two frequency bands, the frequency band group can also be referred to as a frequency band pair or other names. As long as the same technical effect is achieved, frequency band groups are not limited to specific technical terms and can be determined based on actual usage requirements. This embodiment of the application does not impose any limitations.

[0038] The frequency band type indication method, device and apparatus provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0039] like Figure 2 As shown, an embodiment of the present application provides a method for indicating a frequency band type. The method may include:

[0040] S201. The terminal device sends first information to the network device.

[0041] S202: The network device receives the first information.

[0042] The first information may be used to indicate: the frequency band type of each frequency band in the frequency band group of UL TX Switching supported by the terminal device.

[0043] The first information may also be used to indicate a frequency band group of UL TX Switching supported by the terminal device.

[0044] The network device can instruct the terminal device to report its capabilities to the network device by sending a message to the terminal device. For example, the network device can set uplinkTxSwitchRequest to true in the UE-CapabilityRequestFilterCommon information element to instruct the terminal device to report its capabilities to the network device. The terminal device can then report its UL TX Switching capabilities to the network device and, when reporting its UL TX Switching capabilities, indicate to the network device the frequency band type corresponding to each frequency band in the UL TX Switching frequency band group.

[0045] Optionally, the frequency band type of the frequency band in the UL TX Switching frequency band group supported by the terminal device includes at least one of the following:

[0046] (1) A frequency band type that includes one carrier unit.

[0047] (2) A frequency band type consisting of two consecutive carrier units.

[0048] (3) A frequency band type including two non-contiguous carrier units.

[0049] (4) A frequency band type including three carrier wave components: the three carrier wave components include two consecutive carrier wave components and one discontinuous carrier wave component, or the three carrier wave components include three consecutive carrier wave components, or the three carrier wave components include three discontinuous carrier wave components.

[0050] (5) A frequency band type including N carrier components, where the N carrier components include at least one of continuous carrier components and discontinuous carrier components, and N is an integer greater than 3.

[0051] For example, the present embodiment provides four frequency band types:

[0052] Band A: A band containing one CC

[0053] Band B: A band containing one CC or two consecutive CCs

[0054] Band C: A band containing one CC or two non-contiguous CCs

[0055] Band D: A band containing one or three CCs. The three CCs consist of two consecutive CCs and one non-consecutive CC. A terminal device can perform 2TX chains on CCs of different bandwidths in Band D.

[0056] Optionally, the carriers in the frequency band group of UL TX Switching are carriers of the same frequency band type, or the carriers in the frequency band group of UL TX Switching are carriers of different frequency band types.

[0057] Exemplarily, when the frequency band group of UL TX Switching includes two carriers, the two carriers are carriers of the same frequency band type, or carriers of different frequency band types.

[0058] In the case where the frequency band group of UL TX Switching includes three carriers, the three carriers may be carriers of the same frequency band type or carriers of different frequency band types.

[0059] It should be noted that when a frequency band group includes two bands, both bands can be of the same band type to support flexible implementation of terminal devices and flexible configuration of network equipment. This is not the case with the traditional frequency band group where one band is Band A and the other is Band B.

[0060] It can be understood that in the embodiment of the present application, when the frequency band group includes two bands, since the two bands in the frequency band group can be carriers of the same frequency band type or carriers of different frequency band types, it is more conducive to the capability expansion of the terminal device.

[0061] Optionally, this embodiment of the present application provides two methods for reporting the terminal capability indication band type:

[0062] In the first method, the terminal device reports the terminal capability to explicitly indicate the frequency band type.

[0063] Specifically, the first information may include first sub-information and second sub-information, the first sub-information including the UL TX Switching frequency band group supported by the terminal device, and the second sub-information including the frequency band type of each frequency band in the UL TX Switching frequency band group.

[0064] When the network device requests the terminal device to report its capabilities, the terminal device may explicitly inform the network device of the frequency band type of each frequency band in the frequency band group supported by the terminal device in the reported frequency band group information (first information).

[0065] For example, the terminal device may inform the network device of the band type of each band in the band group supported by the terminal device through the ULTxSwitchingBandPair field in the information element BandCombinationList of the capability reporting unit.

[0066] For example, BandCombinationList contains the following information:

[0067] bandTypeUL1-r17 ENUMERATED{bandA,bandB,bandC,bandD};

[0068] bandTypeUL2-r17 ENUMERATED{bandA,bandB,bandC,bandD}.

[0069] The enumeration value of bandTypeUL1 includes bandA, bandB, bandC, and bandD, indicating that the band types of the frequency band UL1 in the band pair include bandA, bandB, bandC, and bandD.

[0070] The enumeration value of bandTypeUL2 includes bandA, bandB, bandC and bandD, indicating that the band types of the frequency band UL2 in the band pair include bandA, bandB, bandC and bandD.

[0071] In the second method, the terminal device reports the terminal capability to implicitly indicate the frequency band type.

[0072] Specifically, the first information includes a UL TX Switching frequency band group supported by the terminal device, and each frequency band in the UL TX Switching frequency band group corresponds to a preset frequency band type.

[0073] When the network device requests the terminal device to report its capabilities, the terminal device can change the bandIndexULx member to an optional configuration in the reported band group information, and implicitly inform the network device of the band type of each band in the band group supported by the terminal device through mapping.

[0074] For example, the terminal device may inform the network device of the band type of each band in the band group supported by the terminal device through the optional member bandIndexULx in the ULTxSwitchingBandPair field in the information element BandCombinationList of the capability reporting unit.

[0075] For example, BandCombinationList contains the following information:

[0076] bandIndexUL1-r17 INTEGER(1..maxSimultaneousBands),OPTIONAL

[0077] bandIndexUL2-r17 INTEGER(1..maxSimultaneousBands),OPTIONAL

[0078] bandIndexUL3-r17 INTEGER(1..maxSimultaneousBands),OPTIONAL

[0079] bandIndexUL4-r17 INTEGER(1..maxSimultaneousBands),OPTIONAL

[0080] Among them, bandIndexUL1-r17, bandIndexUL2-r17, bandIndexUL3-r17 and bandIndexUL4-r17 are all optional.

[0081] It should be noted that since each frequency band in the frequency band group of UL TX Switching corresponds to a preset frequency band type, if there is a field bandIndexUL1-r17 for band combination in the ULTxSwitching container, then this field can be used to indicate that the frequency band type of a frequency band in the frequency band group is band A, otherwise this field does not exist.

[0082] Similarly, if there is a field bandIndexUL2-r17 for band combination, then this field can be used to indicate that the band type of a frequency band in the frequency band group is band B; if there is a field bandIndexUL3-r17 for band combination, then this field can be used to indicate that the band type of a frequency band in the frequency band group is band C; if there is a field bandIndexUL4-r17 for band combination, then this field can be used to indicate that the band type of a frequency band in the frequency band group is band D; otherwise, this field does not exist.

[0083] S203: The network device sends second information to the terminal device.

[0084] S204: The terminal device receives the second information.

[0085] The second information may be used to indicate: the frequency band type of the cell carrier configured for the terminal device.

[0086] Optionally, if the frequency band type of the cell carrier configured for the terminal device is the first frequency band type, the second information may also be used to indicate that the cell carrier configured for the terminal device is the first carrier in the first frequency band type.

[0087] After the network device receives the UL TX Switching capability reported by the terminal device, the network device may indicate to the terminal device the frequency band type of the configured cell carrier and which carrier in the frequency band type the cell carrier is.

[0088] One example is that the network device indicates to the terminal device the frequency band type of the cell carrier and which carrier in the frequency band type the cell carrier is through the following fields in the ServingCellConfig information element.

[0089] UplinkTxSwitching-r17::=SEQUENCE{

[0090] uplinkTxSwitchingPeriodLocation-r17 BOOLEAN,

[0091] uplinkTxSwitchingBandType-r17 ENUMERATED{bandA,bandB,bandC,bandD},

[0092] uplinkTxSwitchingCarrier-r17 ENUMERATED{carrier1,carrier2,Carrier3}

[0093] }

[0094] The enumeration value of uplinkTxSwitchingBandType-r17 includes bandA, bandB, bandC, and bandD, indicating to the terminal device that the cell carrier belongs to the frequency band types including bandA, bandB, bandC, and bandD. The enumeration value of uplinkTxSwitchingCarrier-r17 includes carrier1, carrier2, and Carrier3, indicating that the cell carrier is carrier1, carrier2, and carrier3 among these types.

[0095] Another example is that the network device changes the enumeration value of uplinkTxSwitchingCarrier-r17 to the frequency band type, and the terminal device determines which carrier in the frequency band type the cell carrier is.

[0096] UplinkTxSwitching-r17::=SEQUENCE{

[0097] uplinkTxSwitchingPeriodLocation-r17 BOOLEAN,

[0098] uplinkTxSwitchingCarrier-r17 ENUMERATED{bandA,bandB,bandC,bandD},

[0099] }

[0100] Among them, the enumeration value of uplinkTxSwitchingCarrier-r17 includes bandA, bandB, bandC and bandD, which indicates to the terminal device that the frequency band type of the cell carrier includes bandA, bandB, bandC and bandD.

[0101] An embodiment of the present application provides a frequency band type indication method, wherein a terminal device sends first information for indicating the frequency band type of each frequency band in the frequency band group of UL TX Switching supported by the terminal device to a network device, so that the network device can determine which frequency band type of carrier in UL TX Switching the carrier of the cell configured for the terminal device is, and sends second information for indicating the frequency band type of the cell carrier configured for the terminal device to the terminal device, so that the terminal device can correctly understand the frequency band type of the cell carrier configured by the network device.

[0102] It should be noted that the frequency band type indication method provided in the embodiments of the present application can be executed by a frequency band type indication device, or by a control module in the frequency band type indication device for executing the frequency band type indication method. In the embodiments of the present application, the frequency band type indication device provided in the embodiments of the present application is described by taking the frequency band type indication method executed by the frequency band type indication device as an example.

The sending module 301 can be used to send first information to a network device, where the first information is used to indicate the frequency band type of each frequency band in a frequency band group for UL TX switching that can be supported by the terminal device.

[0104] Optionally, the first information includes first sub-information and second sub-information, the first sub-information includes a frequency band group of UL TX Switching supported by the terminal device, and the second sub-information includes a frequency band type of each frequency band in the frequency band group of UL TX Switching.

[0105] Alternatively, the first information includes a UL TX Switching frequency band group supported by the terminal device, and each frequency band in the UL TX Switching frequency band group corresponds to a preset frequency band type.

[0106] Optionally, the frequency band type of the cell carrier configured for the terminal device is the first frequency band type. The second information is further used to indicate that the cell carrier configured for the terminal device is the first carrier in the first frequency band type.

The sending module 402 can be configured to send second information to the terminal device, where the second information is used to indicate the frequency band type of a cell carrier configured for the terminal device.

[0116] Optionally, the frequency band type of the cell carrier configured for the terminal device is the first frequency band type. The second information is further used to indicate that the cell carrier configured for the terminal device is the first carrier in the first frequency band type.
