Detailed Description

Fig. 1 shows a communication system to which an embodiment of the present application is applied. The communication system comprises a network device and a terminal device. It should be understood that the present application is not limited to the number of network devices and the number of terminal devices included in the communication system.

The terminal device in the embodiments of the present application may be various devices that provide voice and/or data connectivity to a user, and may also be referred to as a terminal, a User Equipment (UE), a mobile station, a mobile terminal, and so on. The terminal may be widely applied to various scenes, for example, device-to-device (D2D), vehicle-to-device (vehicle to everything, V2X) communication, machine-type communication (MTC), internet of things (internet of things, IOT), virtual reality, augmented reality, industrial control, autopilot, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, and the like. The terminal can be a mobile phone, a tablet computer, a computer with a wireless receiving and transmitting function, a wearable device, an aerospace device and the like. In the embodiment of the application, the chip applied to the device can also be called a terminal.

The network device in the embodiment of the present application may be an access network device such as a base station, where the base station may be a base station (base transceiver station, BTS) in a global system for mobile communications (global system of mobile communication, GSM) or code division multiple access (code division multiple access, CDMA), a base station in a wideband code division multiple access (wideband code division multiple access, WCDMA) system, an evolved base station (evolutional nodeB, eNB or eNodeB) in a long term evolution (long term evolution, LTE) system, a next generation base station (next generation NodeB, gNB) in a fifth generation (5th generation,5G) mobile communication system, a next generation base station in a sixth generation (6th generation,6G) mobile communication system, a base station in a future mobile communication system, and so on.

The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the network equipment. For example, the network device may be a module or unit that performs a function of the base station part, for example, may be a Central Unit (CU), or may be a Distributed Unit (DU). Wherein, CU and DU respectively complete a part of protocol stack functions of the base station. Furthermore, the functionality of a CU may be implemented by a plurality of entities, e.g. separating the functionality of the Control Plane (CP) and the User Plane (UP) of the CU, forming a CU control plane (CU-CP) and a CU user plane (CU-UP). For example, CU-CP and CU-UP may be implemented by different functional entities and connected through an E1 interface, and CU-CP and CU-UP may be coupled to DUs.

Currently, the terminal device may report to the network device the band combination supported by the terminal device. Accordingly, the network device may select one of the band combinations supported by the terminal device and generate air interface resource configuration information (or referred to as radio resource configuration information) based on the selected band combination. Further, the network device sends the air interface resource configuration information to the terminal device. The terminal device may check the air interface resource configuration. However, when the terminal device checks the air interface resource configuration information, a problem of compatibility of the terminal device may occur.

The present application proposes two solutions to this technical problem. The two solutions are described in detail below.

As shown in fig. 2, the method 200 may include the steps of:

s201, the terminal device sends a list of band combinations supported by the terminal device to the network device. Accordingly, the network device receives a list of band combinations supported by the terminal device from the terminal device.

The manner in which the terminal device sends the list of the frequency band combinations supported by the terminal device to the network device includes, but is not limited to, the following 3 manners, which may be applied in the scenarios of supplemental uplink (supplemental uplink, SUL), carrier aggregation (carrier aggregation, CA), or dual connectivity (dual connectivity, DC), or in other scenarios, for example, and the application is not limited thereto.

Mode 1:

The terminal device sends the first list to the network device. The first list includes the frequency band combinations supported by the terminal device. The first list is one of a list of band combinations supported by the terminal device.

The first list may be a Band Combination (BC) list, for example.

Mode 2:

The terminal device may send the second list to the network device. The second list includes the band combination supported by the terminal device and the uplink switching capability parameter corresponding to the band combination supported by the terminal device. The second list is another of the list of band combinations supported by the terminal device.

The uplink switching capability parameter is used for indicating uplink switching capability supported by the frequency band combination. The uplink switching capability may be, for example, a switched uplink (switched UL) and/or a dual uplink (dual UL). Switching uplink refers to the terminal device transmitting data in a time division manner on two carriers. The dual uplink refers to that the terminal device may transmit data not only in a time division manner on two carriers, but also with 1 antenna (Tx) on each of the two carriers.

The second list may be, for example, a band combination uplink transmit switch (band combination uplink Tx switch) list.

Mode 3:

the terminal device may send the first list and the second list to the network device. The related description about the first list may refer to mode 1 and the related description about the second list may refer to mode 2.

It should be understood that in this mode 3, the frequency band combinations included in the first list and the frequency band combinations included in the second list may or may not have intersections. For example, the first list includes band combination #1, band combination #2, and band combination #3, and the second list includes band combination #4, band combination #5, and band combination #6. For another example, the first list includes band combination #1, band combination #2, and band combination #3, and the second list includes band combination #3, band combination #4, and band combination #5.

For example, when the network device does not instruct the terminal device to report the second list, the terminal device may report the frequency band combination supported by the terminal device to the network device by sending the first list.

For example, when the network device instructs the terminal device to report the second list, the terminal device may report the frequency band combination supported by the terminal device to the network device by sending the second list.

Optionally, for the above modes 1 to 3, the first list and/or the second list may further include a feature set combination (feature set combination) corresponding to the frequency band combination supported by the terminal device.

The feature set combinations will be described below taking the example that the list of band combinations supported by the terminal device includes the first band combination and the first band combination includes the first band. It should be understood that the number of band combinations included in the list of band combinations supported by the terminal device and the number of bands included in the first band combination are not limited by the present application.

The feature set (feature set) #1 is included in the feature set combinations corresponding to the first band combinations, and the feature set #1 is associated with the first band.

The feature set #1 includes capability information supported by the terminal device on the first frequency band of the first frequency band combination. The capabilities supported by the terminal device on the first frequency band of the first frequency band combination may include a capability at a frequency band level and a capability at a carrier level.

The feature set #1 includes an identification (feature set downlink ID) of at least one downlink feature set and/or an identification (feature set uplink ID) of at least one uplink feature set. The network device may determine the downstream feature set based on the identification of the downstream feature set, and similarly, the network device may determine the upstream feature set based on the identification of the upstream feature set.

The downlink feature set may include an identification (feature set downlink perCC ID) of the at least one carrier-level downlink feature set. The network device may determine the downlink feature set at the carrier level according to the identification of the downlink feature set at the carrier level.

The downlink feature set at the carrier level is used to indicate the capability at the carrier level. For example, carrier level capabilities include, but are not limited to, one or more of the following:

The method comprises the steps of supporting downlink modulation orders (supported modulation order DL), supporting downlink bandwidths (supported band width DL), supporting downlink subcarrier intervals (supported subcarrier SPACING DL) and maximum MIMO layers (max number MIMO layers).

Similarly, the uplink feature set may include an identification (feature set uplink perCC ID) of the at least one carrier-level uplink feature set. The network device may determine the uplink feature set at the carrier level according to the identification of the uplink feature set at the carrier level.

Optionally, the terminal device may further send an identification of at least one feature set corresponding to the first frequency band in the first frequency band combination to the network device. Accordingly, the network device receives an identification of at least one feature set corresponding to a first frequency band in the first frequency band combination.

Wherein the identification of the at least one feature set may include one or more of:

The method comprises the steps of identifying at least one uplink feature set, identifying at least one downlink feature set, identifying at least one carrier-level uplink feature set of a first uplink feature set, and identifying at least one carrier-level downlink feature set of a first downlink feature set.

The at least one uplink feature set may include a first uplink feature set, and the at least one downlink feature set may include a first downlink feature set.

S202, the network equipment selects a first frequency band combination from a list of frequency band combinations supported by the terminal equipment, and generates air interface resource configuration information based on the first frequency band combination.

As an implementation, the network device may select a band combination from a list of band combinations supported by the terminal device according to air interface resources of the network device (the selected band combination may be denoted as a first band combination). Further, the network device generates the air interface resource configuration information based on the first frequency band combination.

Several ways in which the network device selects the first band combination are described below.

Mode a:

if the manner in which the terminal device transmits the band combinations supported by the terminal device to the network device in S201 is mode 1, the network device selects a band combination from the first list.

For example, the first list includes a band combination #1 and a band combination #2, wherein the band combination #1 is suitable for a carrier aggregation and supplementary uplink scenario, and the band combination #2 is suitable for a dual connection scenario. When the terminal device performs carrier aggregation, the network device may select the band combination #1 from the first list.

For another example, the first list includes a band combination #1, a band combination #2, and a band combination #3, where the band combination #1 and the band combination #2 are both applicable to a carrier aggregation scenario, the band combination #3 is applicable to a dual connection scenario, the feature set combination corresponding to the band combination #1 indicates that the maximum mimo layer number corresponding to the band combination #1 is 1 layer (one layer), and the feature set combination corresponding to the band combination #2 indicates that the maximum mimo layer number corresponding to the band combination #2 is 2 layers (two layers). When the terminal device is configured for carrier aggregation and the terminal device requests the network device to select a band combination having a maximum mimo layer number of 2 layers, the network device may select band combination #2 from the first list.

Mode B:

if the manner in which the terminal device sends the band combinations supported by the terminal device to the network device in S201 is mode 2, the network device selects a band combination from the second list.

For example, the second list includes a band combination #a and a band combination #b, where an uplink switching capability parameter corresponding to the band combination #a indicates switching uplink (switched UL), and an uplink switching capability parameter corresponding to the band combination #b indicates dual uplink (dual UL). In a scenario supporting dual upstream, the network device may select the band combination #b from the second list.

Mode C:

If the manner in which the terminal device transmits the band combination supported by the terminal device to the network device in S201 is mode 3, the network device selects the band combination from the first list or the second list.

As a possible scenario, in a multi-carrier round robin scenario, the network device may preferentially select a combination of frequency bands from the second list. In other scenarios, the network device may select a band combination from the first list. That is, the network device may choose to use the first list or the second list according to different requirements, for example, requirements of different scenes, and further choose a band combination for the terminal device.

Alternatively, when the feature set combination is included in the list of the band combinations supported by the terminal device, if the terminal device also transmits, in S201, an identification of at least one feature set corresponding to the first band in the first band combination to the network device, the network device may also select a feature set from the at least one feature set (the selected feature set may be denoted as the first feature set). Further, the network device generates air interface resource configuration information according to the first frequency band combination and the first feature set.

As one case, the first frequency band in the first frequency band combination corresponds to a plurality of uplink feature sets from which the network device may select. Assuming that the network device selects the first uplink feature set, if the first uplink feature set corresponds to a plurality of uplink feature sets at a carrier level, the network device may select from the plurality of uplink feature sets at the carrier level.

For example, the plurality of uplink feature sets at the carrier level include an uplink feature set #1 at the carrier level and an uplink feature set #2 at the carrier level, the maximum mimo layer number corresponding to the uplink feature set #1 at the carrier level is 1, and the maximum mimo layer number corresponding to the uplink feature set #2 at the carrier level is 2. The terminal device may request the network device to select an uplink feature set of a carrier level with a maximum mimo layer number of 1, and the network device may select an uplink feature set #1 of a carrier level from a plurality of uplink feature sets of a carrier level according to the request of the terminal device.

As another case, the first frequency band in the first frequency band combination corresponds to a plurality of downlink feature sets from which the network device may select. Assuming that the network device selects the first downlink feature set, if the first downlink feature set corresponds to a plurality of downlink feature sets at a carrier level, the network device may select from the plurality of downlink feature sets at the carrier level.

And S203, the network equipment sends the air interface resource configuration information and the identification of the first frequency band combination to the terminal equipment. Accordingly, the terminal device receives the air interface resource configuration information and the identification of the first frequency band combination from the network device.

The identification of the first frequency band combination may be, for example, the relative position information of the first frequency band combination in the list of frequency band combinations supported by the terminal device, but may also be other information capable of identifying the first frequency band combination.

For example, the first band combination is the first band combination in the first list, and the identification of the first band combination may be "1".

In order to further increase the accuracy of the terminal device in determining the combination of frequency bands selected by the network device, the network device may optionally also send identification information of the list to the terminal device.

As one way, if the first band combination is selected from the first list by the network device, the network device may send the identification information of the first list to the terminal device. For example, the identification information of the first list may be type information of the first list.

Alternatively, if the first band combination is selected by the network device from the second list, the network device may send the identification information of the second list to the terminal device. For example, the identification information of the second list may be referred to as type information of the second list.

When the manner in which the network device selects the first band combination is manner C of S202, and the first band combination is the first band combination in the first list, the identifier of the first band combination may be "1". Since the identification of the first band combination in the second list may also be "1", the band combination determined by the terminal device according to the identification of the first band combination may be the first band combination in the second list. Therefore, the network device sends the identification information of the list to the terminal device, so that the accuracy of the terminal device in determining the frequency band combination selected by the network device can be further improved, and the probability of occurrence of the compatibility problem of the terminal device is reduced.

Alternatively, the network device may also send the identification of the first feature set selected in S202 to the terminal device.

Assume that: the network device selects a first uplink feature set from the plurality of uplink feature sets, and selects an uplink feature set of a certain carrier level from the plurality of uplink feature sets of carrier levels corresponding to the first uplink feature set.

As one way, the network device may send the identification of the first set of uplink features to the terminal device.

As another approach, the network device may send the identification of the first uplink feature set and the identification of the selected carrier level uplink feature set to the terminal device.

As another approach, the network device may send the identification of the selected carrier level uplink feature set to the terminal device.

Further, as a possible case, the feature set at the carrier level corresponds to carriers one by one, and carriers correspond to cells one by one.

In this case, the network device may send the identification of the selected carrier level feature set to the terminal device, and the terminal device may determine the cell associated with the carrier level feature set, then access the cell, and communicate with the network device based on the carrier corresponding to the cell.

Or in this case the network device may send the identity (cell index) of the cell associated with the feature set at the carrier level to the terminal device. The terminal equipment can determine the characteristic set of the carrier level selected by the network equipment according to the cell identifier, and access the cell indicated by the cell identifier, and communicate based on the carrier corresponding to the cell.

There is also a possibility that the feature set at the carrier level corresponds to carriers one by one, and the correspondence between carriers and cells is one-to-many (i.e., the same carrier may be multiplexed by multiple cells).

In this case, the network device may send the identifier of the selected carrier level feature set and the identifier of the cell associated with the carrier level feature set to the terminal device, and the terminal device may access the cell indicated by the cell identifier, so that the probability that the terminal device accesses the wrong cell may be reduced.

As a possible implementation, for S203, the network device may send a cell to the terminal device, where the cell may include an identifier of the first frequency band combination, and optionally one or more of identification information of the list, an identifier of the first feature set, and an identifier of the cell. The cell may be a newly added cell or a cell defined in a protocol (e.g., there are reserved bits in a defined cell, and the network device may use the reserved bits to transmit), which is not limited by the present application.

S204, the terminal equipment checks the air interface resource configuration information according to the identification of the first frequency band combination.

Specifically, the terminal device determines the first frequency band combination according to the identification of the first frequency band combination, and verifies the air interface resource configuration information based on the first frequency band combination.

Optionally, if the network device further transmits the identification information of the first list to the terminal device in S203, the terminal device may determine the first band combination from the first list according to the identification information of the first list and the identification of the first band combination, and verify the air interface resource configuration information based on the first band combination.

Optionally, if the network device further transmits the identification information of the second list to the terminal device in S203, the terminal device may determine the first band combination from the second list according to the identification information of the second list and the identification of the first band combination, and verify the air interface resource configuration information based on the first band combination.

Optionally, if the network device further sends the identifier of the first feature set to the terminal device in S203, the terminal device may determine the first frequency band combination and the first feature set according to the identifier of the first frequency band combination and the identifier of the first feature set, and verify the air interface resource configuration information based on the first frequency band combination and the first feature set.

It will be appreciated that one possible reason for the problem of compatibility of the terminal device is that the terminal device does not know which combination of frequency bands the network device has selected. Specifically, the terminal device estimates the frequency band combination selected by the network device according to a parameter in the air interface resource configuration information, for example, a maximum rank number (maxRank) parameter. And the terminal equipment checks the air interface resource allocation information according to the estimated frequency band combination. Since the band combination presumed by the terminal device may not be the band combination selected by the network device, a problem of terminal device compatibility may occur when the terminal device uses the wrong band combination to check the air interface resource configuration information.

As can be seen from the above method 200, the network device may send the relevant information of the selected frequency band combination to the terminal device, and the terminal device may verify the air interface resource configuration information according to the frequency band combination selected by the network device, thereby reducing the probability that the terminal device uses the wrong frequency band combination to verify the air interface resource configuration information, and reducing the probability of occurrence of the compatibility problem of the terminal device.

As shown in fig. 3, as a second solution (method 300), the terminal device may start a process of traversing the list of band combinations according to the air interface configuration information, and find a band combination matching the air interface resource configuration information in the list of band combinations.

Specifically, the method 300 includes:

s301, the terminal device sends a list of band combinations supported by the terminal device to the network device. Accordingly, the network device receives a list of band combinations supported by the terminal device from the terminal device.

Regarding this S301, reference may be made to the related description in S201.

S302, the network device selects a first frequency band combination from a list of frequency band combinations supported by the terminal device, and generates air interface resource configuration information based on the first frequency band combination.

Regarding this S302, reference may be made to the related description in S202.

S303, the network equipment sends air interface resource configuration information to the terminal equipment. Correspondingly, the terminal equipment receives the air interface resource configuration information from the network equipment.

Illustratively, the parameters in the air interface resource configuration information include, but are not limited to, one or more of the following:

the first parameter, the second parameter, the third parameter and the fourth parameter.

Wherein the first parameter indicates a carrier unit (component carrier, CC) bandwidth, the second parameter indicates the number of antenna ports for transmitting a Physical Uplink Shared Channel (PUSCH) SHARED CHANNEL, the third parameter indicates a maximum rank number for transmitting PUSCH (maxRank), and the fourth parameter indicates a subcarrier spacing (subcarrier spacing, SCS).

S304, the terminal equipment determines the frequency band combination matched with the air interface resource configuration information according to the air interface resource configuration information.

For example, the terminal device starts a process of traversing the list of band combinations supported by the terminal device according to the air interface resource configuration information, and determines a band combination matched with the air interface resource configuration information in the list of band combinations supported by the terminal device.

Wherein a certain frequency band combination matched with the air interface resource configuration information satisfies at least one of the following conditions:

Condition 1: the first parameter is matched with a carrier unit bandwidth corresponding to the band combination.

Condition 2: the second parameter matches a multiple-in multiple-out (MIMO) layer number corresponding to the band combination.

Condition 3: the third parameter is matched to a maximum rank number corresponding to the band combination.

Condition 4: the fourth parameter is matched to the subcarrier spacing corresponding to the band combination.

Illustratively, the greater the number of parameters that a band combination matches in the air interface configuration information, the greater the likelihood that the band combination will be the band combination selected by the network device.

Assume that: the frequency band combination matched with the air interface resource configuration information is a frequency band combination satisfying the above conditions 1 to 4, and the traversing flow of the terminal device can be divided into the following 3 cases.

Case 1:

In S301 the terminal device sends a first list to the network device, which the terminal device traverses in S304. As shown in fig. 4, when a certain frequency band combination in the first list satisfies the above-described conditions 1 to 4, the frequency band combination is a frequency band combination matching with the air interface resource allocation information.

Case 2:

The terminal device sends a second list to the network device in S301, and traverses the second list in S304. As shown in fig. 5, when a certain band combination in the second list satisfies the above-described conditions 1 to 4, the band combination is a band combination matching with the air interface resource allocation information.

Case 3:

In S301, if the terminal device reports the first list and the second list to the network device, the terminal device traverses the first list and the second list. For example, the terminal device traverses the first list first, and if no band combination matching with the air interface resource configuration information exists in the first list, the terminal device continues to traverse the second list.

As shown in fig. 6, when a certain band combination in the first list or the second list satisfies the above-described conditions 1 to 4, the band combination is a band combination matching with the air interface resource allocation information.

Based on the result of the traversal performed by the network device in S304, the method 300 can be further divided into the following two cases.

Optionally, as a first case, the method 300 further includes S305:

s305, when the air interface resource configuration information is matched with the first frequency band combination, the terminal equipment verifies the air interface resource configuration information based on the first frequency band combination.

Optionally, as a second case, the method 300 further includes S306:

S306, when there is no band combination matching with the air interface resource configuration information in the list of band combinations supported by the terminal device, the terminal device executes a radio resource control (radio resource control, RRC) reestablishment procedure.

It will be appreciated that the terminal device may also perform other actions when there are no band combinations in the list of band combinations supported by the terminal device that satisfy the above conditions 1 to 4. For example, the terminal device may lower the matching criterion, and find a band combination satisfying 3 conditions (e.g., condition 1 to condition 3) out of the above 4 conditions from the band combination list supported by the terminal device.

According to the embodiment of the application, the terminal equipment can traverse the list of the frequency band combinations supported by the terminal equipment to find the frequency band combinations matched with the air interface resource configuration information, so that the probability of checking the air interface resource configuration information by using the wrong frequency band combinations by the terminal equipment is reduced, and the probability of occurrence of the problem of compatibility of the terminal equipment is reduced.
