In the embodiment of the present application, the apparatus for implementing the function of the terminal may be the terminal, or may be an apparatus capable of supporting the terminal to implement the function, for example, a chip system. In the embodiment of the present application, a device for implementing a function of a terminal is a terminal, and a terminal is a UE as an example, so as to describe a technical solution provided in the embodiment of the present application.

The network device according to the embodiment of the present application includes a Base Station (BS), which may be a device deployed in a wireless access network and capable of performing wireless communication with a terminal. The base station may have various forms, such as a macro base station, a micro base station, a relay station, an access point, and the like. For example, the base station related to the embodiment of the present application may be a base station in 5G or a base station in LTE, where the base station in 5G may also be referred to as a Transmission Reception Point (TRP) or a gNB. In this embodiment of the present application, the apparatus for implementing the function of the network device may be a network device, or may be an apparatus capable of supporting the network device to implement the function, for example, a chip system. In the embodiment of the present application, a device for implementing a function of a network device is a network device, and a network device is a base station, for example, the technical solution provided in the embodiment of the present application is described.

In a wireless communication system, a base station and a UE may communicate using air interface resources, where the air interface resources include time domain resources and/or frequency domain resources. BWP may be configured in frequency domain resources, where BWP may include a continuous segment of frequency resources in carrier bandwidth, system bandwidth or transmission bandwidth, for example, BWP shown in fig. 1 is a continuous segment of frequency resources in carrier bandwidth; BWP may include non-contiguous frequency resources in a carrier bandwidth, a system bandwidth, or a transmission bandwidth, which is not limited in this application. When the BWP is a continuous piece of frequency resource, the BWP may also be referred to as sub-band (subband), narrowband (narrowband), or other names, which is not limited in this application. Illustratively, in an Orthogonal Frequency Division Multiplexing (OFDM) based system, such as NR or LTE, BWP may include one or more subcarriers, one or more Resource Blocks (RBs), or one or more Resource Block Groups (RBGs) in which frequency domains are contiguous. Wherein, in frequency domain, one RB may include one or more subcarriers, for example, one RB may include 12 subcarriers, and the corresponding subcarrier spacing may be 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, 480KHz or other 15KHz × 2 KHzⁿAnd n is an integer. One RBG may include one or more RBs. In the embodiment of the present application, the plurality may be a positive integer of 2, 3, 4, or more than 4; the integer can be a negative integer, such as-1, -2, -3, or other negative integer less than-3Counting; the integer may also be 0; the integer may also be a positive integer, such as 1, 2, 3, or other positive integer greater than 3.

For a signal that may be transmitted between the base station and UE a, the transmission resources for the signal may be configured in one or more BWPs, i.e., the base station and UE a may transmit the signal in one or more BWPs. The one or more BWPs may be configured BWPs for the UE a or common BWPs, which is not limited in this application. The common BWP may be a BWP configured for a group of UEs, where the group of UEs includes UE a, and the group of UEs may be some UEs in a cell or all UEs in the cell, which is not limited in this application. Illustratively, the UE may be configured with one or more BWPs by pre-configuration, or the base station may be configured with one or more BWPs by signaling.

For multiple BWPs, parameter values may be configured independently for different BWPs, which may be used to meet the requirements of different communication scenarios or communication services. The values of the parameters for different BWPs may or may not be the same, and the application is not limited thereto. Where a parameter may also be referred to as numerology, the parameter may include one or more of: subcarrier spacing, Cyclic Prefix (CP) length, time unit length, and bandwidth size. The time unit may be a sampling time interval, symbol, slot, minislot, subframe, sub-subframe, radio frame, or Transmission Time Interval (TTI). The time unit length may be expressed as a time domain length, which may be in units of seconds, milliseconds, microseconds, or the like. The time unit length may also be expressed as one or more sampling points, one or more symbols, one or more minislots, one or more slots, one or more subframes, or one or more radio frames. Illustratively, the length of one slot may be represented as 14 symbols, and the length of one radio frame may be represented as 10 subframes.

In this embodiment of the present application, a BWP configured for a UE may be used as an uplink BWP and a downlink BWP at the same time, that is, the BWP may be used for downlink transmission or uplink transmission; uplink BWP and downlink BWP may also be configured for the UE independently, which is not limited in this application.

The UE and the base station perform uplink transmission in uplink BWP and perform downlink transmission in downlink BWP.

In one serving cell or carrier, when the base station configures multiple BWPs for the UE, the following two scenarios may be included according to the active state of the BWPs:

(1) activating a BWP: when a base station configures multiple BWPs for a UE, one of the BWPs may be activated, and the activated BWP is used for the base station to communicate with the UE. Further, the base station may also deactivate a BWP that has been previously activated, and the deactivated BWP may no longer be used for the base station to communicate with the UE since being deactivated or after a period of time since being deactivated.

(2) Allowing simultaneous activation of multiple BWPs: when the base station configures multiple BWPs for the UE, it may also allow simultaneous activation of multiple BWPs in the multiple BWPs, and the activated multiple BWPs may be used for communication between the base station and the UE at the same time to improve the data transmission rate. Further, in a scenario where simultaneous activation of multiple BWPs is allowed, activation of one BWP may also be allowed. Illustratively, when the base station configures N for the UE_BWPWhen BWP are multiple, it may be allowed to activate the N simultaneously_BWPN in BWP_xBWP, N_BWPIs a positive integer, N_xIs a value in the range of 1 to N_BWPIs an integer of (1).

In order to allow simultaneous activation of multiple BWPs in one serving cell or carrier, the following BWP packet based design is proposed. When multiple BWPs are allowed to be activated simultaneously, one or more BWPs may be activated. If multiple BWPs are activated, the activated multiple BWPs may be included in one or more BWP packets.

BWP packet design one

N configured for UE_BWPThe BWPs may be configured or represented as N^GA BWP group of N^GIncluding in the ith BWP group of the BWP groupsBWP, Ni_BWPIs a positive integer. A BWP group may includeAn upstream BWP andthe number of the downstream BWPs is small,andis a positive integer. In the present embodiment, a BWP group may also be referred to as a BWP packet.

In this design, BWPs may be paired.

In one possible implementation, one BWP pair may include upstream BWPs in one BWP packet, or one BWP pair may include downstream BWPs in one BWP packet. For one BWP of a BWP pair, the BWPs of the BWP pair other than the BWP are the pairing BWPs of the BWP. For example, one BWP pair includes two upstream BWPs: BWPA, BWP B is the BWP-pair of BWP a, BWP a is the BWP-pair of BWP B. For another example, a BWP pair includes three downstream BWPs: BWP C, BWP D, BWP E is BWP of BWP C's pairing, BWP C, BWP D is BWP of BWP E's pairing. In practical applications, there may be other examples, which are not limited herein.

Further, in one BWP group, a paired BWP and an unpaired BWP may be included. Illustratively, one BWP group includes BWP a, BWP B, BWP C, BWP D, BWP E and BWP F. The first BWP pair comprises BWP A and BWP B, and the second BWP pair comprises BWP C, BWP D and BWP E. At this time, BWP a, BWP B, BWP C, BWP D and BWP E in the BWP group can be considered as paired BWP, and BWP F is considered as non-paired BWP. It may also be considered that the BWP group includes 3 BWP subgroups, and one BWP subgroup includes one or more BWPs, and in this example, it may be considered that the first BWP subgroup includes BWPA and BWP B, the second BWP subgroup includes BWP C, BWP D and BWP E, and the third BWP subgroup includes BWP F. That is, in the present application, a BWP group may include a positive integer number of BWP subgroups, and a BWP subgroup may include a positive integer number of BWPs.

One BWP pair may include one or more upstream BWPs and one or more downstream BWPs. For one BWP of a BWP pair, the BWPs of the BWP pair other than the BWP are the pairing BWPs of the BWP. For example, one BWP pair includes two upstream BWPs: BWP A, BWP B, comprising two downlink BWPs: BWP C and BWP D, BWP B, BWP C and BWP D are the BWP pairs of BWPA, BWP a, BWP C and BWP D are the BWP pairs of BWP B, BWP a, BWP B and BWP D are the BWP pairs of BWP C, and BWP a, BWP B and BWP C are the BWP pairs of BWP D. For another example, a BWP pair includes an upstream BWP E and a downstream BWP F, where BWP E is the BWP pairing of BWP F and BWP F is the BWP pairing of BWP E. As another example, a BWP pair includes an upstream BWP G, and two downstream BWPs: BWP H and BWP J, BWP H and BWP J being BWP G and BWP J and BWP H and BWP J. In practical applications, there may be other examples, which are not limited herein.

In one possible implementation, each upstream BWP in a BWP group has one or more downstream BWPs paired with the BWP within the BWP group, and each downstream BWP in a BWP group has one or more upstream BWPs paired with the BWP within the BWP group. In another possible implementation, at least one upstream BWP exists in a BWP group, and no downstream BWP is paired with the upstream BWP; or at least one downstream BWP exists in the BWP group, and there is no upstream BWP paired with the downstream BWP.

In this design, activation of BWP group granularity may be performed. Illustratively, when one BWP group is activated, a first activation downstream BWP and a first activation upstream BWP in the BWP group are activated. The first activated downlink BWP may be one or more preconfigured downlink BWPs, or one or more configured downlink BWPs configured for the UE by the base station through signaling, which may also be referred to as a specific downlink BWP, a downlink BWP to be activated, or other names; the first active uplink BWP may be one or more preconfigured BWPs, or one or more configured BWPs configured by the base station for the UE through signaling, which may also be referred to as a specific uplink BWP, an uplink BWP to be activated, or by other names, which is not limited in this application. Further illustratively, upon activation of one BWP group, a first active BWP pair in the BWP group is activated. The first active BWP pair may be a preconfigured BWP pair, or a BWP pair configured by the base station for the UE through signaling, which may also be referred to as a specific BWP pair, a BWP pair to be activated, or other names, which is not limited in this application. Activating one BWP pair activates all BWPs in the BWP pair. In the present embodiment, activation of one or more BWP groups may be allowed.

In this design, activation of the granularity by BWP may also be performed. In one possible implementation, activating one BWP pair activates all BWPs in the BWP pair; deactivating the BWP pair deactivates all BWPs in the BWP pair. Or, when one BWP is activated, all BWPs paired with the BWP are activated; when one BWP is activated, all BWPs paired with that BWP are activated.

In the design, if a BWP group is in an active state, there is at least one active upstream BWP and at least one active downstream BWP in the BWP group; when a BWP group is in a deactivated state, all upstream BWPs and all downstream BWPs in the BWP group are deactivated.

(II) BWP packet design II

N configured for UE_BWPThe BWPs may be configured or represented as N^GA BWP group of N^GThe ith BWP group in the BWP groups consists of Nⁱ _BWPAn ascending BWP, namely the ith BWP group is an ascending BWP group; or the N^GThe ith BWP group in the BWP groups consists of Nⁱ _BWPThe downstream BWP is formed, i.e. the ith BWP group is a downstream BWP group, wherein Nⁱ _BWPIs a positive integer.

In one possible implementation, one BWP pair may include multiple upstream BWPs in one upstream BWP packet, or one BWP pair may include multiple downstream BWPs in one downstream BWP packet. For one BWP of a BWP pair, the BWPs of the BWP pair other than the BWP are the pairing BWPs of the BWP. For example, one BWP pair includes two upstream BWPs: BWP a, BWP B is the BWP pairing of BWP a and BWP a is the BWP pairing of BWP B. For another example, a BWP pair includes three downstream BWPs: BWP C, BWP D, BWP E is BWP of BWP C's pairing, BWP C, BWP D is BWP of BWP E's pairing. In practical applications, there may be other examples, which are not limited herein.

Further, in one downstream BWP group or one upstream BWP group, a paired BWP and a non-paired BWP may be included. Illustratively, one downstream BWP group includes BWP a, BWP B, BWP C, BWP D, BWP E and BWP F. The first BWP pair comprises BWP A and BWP B, and the second BWP pair comprises BWP C, BWP D and BWP E. At this time, BWP a, BWP B, BWP C, BWP D and BWP E in the BWP group can be considered as paired BWP, and BWP F can be considered as unpaired BWP. It may also be considered that the BWP group includes 3 BWP subgroups, and one BWP subgroup includes one or more BWPs, and in this example, it may be considered that the first BWP subgroup includes BWP a and BWP B, the second BWP subgroup includes BWP C, BWP D and BWP E, and the third BWP subgroup includes BWP F. That is, in the present application, a BWP group may include a positive integer number of BWP subgroups, and a BWP subgroup may include a positive integer number of BWPs.

In one possible implementation, one upstream BWP group and one downstream BWP group may be paired or paired. One BWP pair may include one or more upstream BWPs in the upstream BWP group and one or more downstream BWPs in the downstream BWP group. For one BWP of a BWP pair, the BWPs of the BWP pair other than the BWP are the pairing BWPs of the BWP. For example, the upstream BWP group a includes three upstream BWPs: BWP A, BWP B and BWP C, the downstream BWP group a includes two downstream BWPs: BWP D and BWP E, and the upstream BWP group a corresponds to the downstream BWP group a. The BWPs in the upstream BWP group a may be paired with the BWPs in the downstream BWP group a. For example, a BWP pair includes BWP a, BWP B, and BWP D, BWP B and BWP D being BWP pairs of BWP a, BWP a and BWP D being BWP pairs of BWP B, and BWP a and BWP B being BWP pairs of BWP D. For another example, a BWP pair includes BWP C and BWP E, BWP C being the BWP E pairing BWP, BWP E being the BWP C pairing BWP.

In one possible implementation, for any one BWP in an upstream BWP group, there are one or more downstream BWPs paired with the any one BWP in the downstream BWP group to which the upstream BWP group corresponds; for any one BWP in a downstream BWP group, there are one or more upstream BWPs paired with the any one BWP in the upstream BWP group corresponding to the downstream BWP group. In another possible implementation, for at least one BWP in an upstream BWP group, there is no downstream BWP paired with the at least one BWP in the downstream BWP group to which the upstream BWP group corresponds; or for at least one BWP in one downlink BWP group, there is no uplink BWP paired with the at least one BWP in the uplink BWP group corresponding to the downlink BWP group.

In this design, activation of the granularity by BWP configuration may be performed. Illustratively, when a BWP group pair is activated, the first active upstream BWP in the upstream BWP group in the BWP group pair is activated, and the first active downstream BWP in the downstream BWP group in the BWP group pair is activated. The first activated downlink BWP in the downlink BWP group may be a preconfigured downlink BWP, or a BWP configured by the base station for the UE through signaling, which may also be referred to as a specific downlink BWP, a downlink BWP to be activated, or other names; the first active uplink BWP in the uplink BWP group may be a preconfigured BWP, or a BWP configured by the base station for the UE through signaling, which may also be referred to as a specific uplink BWP, an uplink BWP to be activated, or by other names, which is not limited in this application. In embodiments of the present application, activation of one or more BWP group pairings may be allowed.

Further illustratively, a first active BWP pair is activated when a BWP group pair is activated, the upstream BWP in the first active BWP pair being included in the upstream BWP group in the BWP group pair, and the downstream BWP in the first active BWP pair being included in the downstream BWP group in the BWP group pair. The first active BWP pair may be a preconfigured BWP pair, or a BWP pair configured by the base station for the UE through signaling, which may also be referred to as a specific BWP pair, a BWP pair to be activated, or by other names, which is not limited in this application.

In this design, activation of BWP group granularity may also be performed. Illustratively, when an upstream BWP group is activated, a first activated upstream BWP in the BWP group is activated, and optionally, a first activated downstream BWP in a downstream BWP group corresponding to the upstream BWP group is activated; when a downstream BWP group is activated, a first activated downstream BWP in the BWP group is activated, and optionally, a first activated upstream BWP in an upstream BWP group corresponding to the downstream BWP group is activated. The first activated downlink BWP in the downlink BWP group may be a preconfigured downlink BWP, or a BWP configured by the base station for the UE through signaling, which may also be referred to as a specific downlink BWP, a downlink BWP to be activated, or other names; the first active uplink BWP in the uplink BWP group may be a preconfigured BWP, or a BWP configured by the base station for the UE through signaling, which may also be referred to as a specific uplink BWP, an uplink BWP to be activated, or by other names, which is not limited in this application. In embodiments of the present application, activation of one or more upstream BWP groups and/or activation of one or more downstream BWP groups may be allowed.

Further illustratively, when one upstream BWP group is activated, the downstream BWP group corresponding to the upstream BWP group is activated, and a first activated BWP pair is activated, where the upstream BWP in the first activated BWP pair is included in the upstream BWP group, and the downstream BWP in the first activated BWP pair is included in the downstream BWP group. When a downstream BWP group is activated, the upstream BWP group corresponding to the downstream BWP group is activated, and a first activated BWP pair is activated, where an upstream BWP in the first activated BWP pair is included in the upstream BWP group, and a downstream BWP in the first activated BWP pair is included in the downstream BWP group. The first active BWP pair may be a preconfigured BWP pair, or a BWP pair configured by the base station for the UE through signaling, which may also be referred to as a specific BWP pair, a BWP pair to be activated, or by other names, which is not limited in this application.

In this design, activation of the granularity by BWP may also be performed. In one possible implementation, activating one BWP pair activates all BWPs in the BWP pair; deactivating the BWP pair deactivates all BWPs in the BWP pair. Or, when one BWP is activated, all BWPs paired with the BWP are activated; when one BWP is deactivated, all BWPs paired with that BWP are deactivated. In the design, if an upstream BWP group is in an active state, there is at least one active upstream BWP in the upstream BWP group, and if a downstream BWP group is in an active state, there is at least one active downstream BWP in the downstream BWP group; when one upstream BWP group is in a deactivated state, all upstream BWPs in the upstream BWP group are deactivated, and when one downstream BWP group is in a deactivated state, all downstream BWPs in the downstream BWP group are deactivated. In the above two BWP packet designs, optionally, for a BWP pair, the frequency domain centers of at least one upstream BWP and one downstream BWP in the BWP pair are aligned. For example, a BWP pair includes an upstream BWP a and a downstream BWP B, with the frequency domain centers of BWP a and BWP B aligned. As another example, a BWP pair includes two upstream BWPs: BWP a and BWP B, and two downlink BWPs: BWP C and BWP D, wherein the frequency domain centers of BWP a and BWP B are aligned and/or the frequency domain centers of BWP C and BWP D are aligned.

It should be noted that, the BWP packet design one and the packet design two and their related designs are also within the scope of the present application, and the base station and the UE may perform data transmission in one or more BWPs configured for the UE by the base station.

In the implementation of the present application, the technical features may be distinguished by first, second, third, fourth, A, B, C, D, E, or F, and the like, and the technical features described therein have no sequential relationship, such as a sequential relationship or a size relationship.

In the embodiment of the present application, the BWP groups configured for different UEs may be the same or different, and the application is not limited thereto. Illustratively, the same scenario for BWP groups configured for different UEs is a cell-level BWP group, which is used for transmission of cell common signals.

In the above BWP packet design, for a BWP group, how to configure resources for signals transmitted in the BWP group is a technical problem that must be solved, otherwise, data transmission cannot be achieved. In order to solve the technical problem, the embodiments of the present application provide the following designs and corresponding methods. The resource allocation for the signal may also be referred to as scheduling, and the resource allocation may be performed for the signal through scheduling information.

Designing a first mode: Cross-BWP group scheduling

When the BWP packet is designed as a BWP packet design one, and a resource is configured for a BWP group for a signal transmitted in the BWP group, it is considered that the scheduling information of the signal can be transmitted in BWPs outside the BWP group. Optionally, it is considered that the scheduling information of the signal may also be transmitted in the BWP group.

When the BWP packet is designed as the BWP packet design two, and a resource is configured for a signal transmitted in an uplink BWP group, it is considered that the scheduling information of the signal can be transmitted in BWPs other than the downlink BWP group corresponding to the uplink BWP group. Optionally, it is considered that the scheduling information of the signal may also be transmitted in the downlink BWP group corresponding to the uplink BWP group.

When the BWP packet is designed as BWP packet design two, for a downlink BWP group, when resource allocation is performed on a signal transmitted in the BWP group, it is considered that the scheduling information of the signal can be transmitted in BWPs outside the downlink BWP group. Optionally, it is considered that the scheduling information of the signal may also be transmitted in the downlink BWP group.

Designing two: BWP group self-contained scheduling

When a BWP packet is designed as a BWP packet design one, for a BWP group, when resource configuration is performed on a signal transmitted in the BWP group, it is considered that scheduling information of the signal is transmitted in the BWP group.

When the BWP packet is designed as BWP packet design two, and for an uplink BWP group, when resource allocation is performed on a signal transmitted in the BWP group, it is considered that the scheduling information of the signal is transmitted in the downlink BWP group corresponding to the uplink BWP group.

When the BWP packet is designed as the BWP packet design two, for a downlink BWP group, when resource allocation is performed on a signal transmitted in the BWP group, it is considered that the scheduling information of the signal is transmitted in the downlink BWP group.

Designing three steps: scheduling a first Signal + BWP group self-contained scheduling A second Signal across BWP groups

When the BWP packet is designed as a BWP packet design one, for one BWP group, the first signal and the second signal may be transmitted in the BWP group, and when the resource configuration is performed on the first signal and the second signal, it is considered that the scheduling information of the first signal may be transmitted in BWPs outside the BWP group, and it is considered that the scheduling information of the second signal is transmitted in the BWP group. It is optionally considered that the scheduling information of the first signal may also be transmitted in the BWP group.

When the BWP packet is designed as a BWP packet design two, for an uplink BWP group, when the first signal is an uplink signal, performing resource allocation on the first signal, and considering that the scheduling information of the first signal can be transmitted in BWPs other than the downlink BWP group corresponding to the uplink BWP group; and when the second signal is an uplink signal, performing resource allocation on the second signal, and considering that the scheduling information of the first signal is transmitted in a downlink BWP group corresponding to the uplink BWP group. Optionally, it is considered that the scheduling information of the first signal may also be transmitted in the downlink BWP group corresponding to the uplink BWP group.

When the BWP packet is designed as BWP packet design two, for a downlink BWP group, when the first signal is a downlink signal, performing resource allocation on the first signal, and considering that the scheduling information of the first signal can be transmitted in BWPs outside the downlink BWP group; and when the second signal is an uplink signal, performing resource configuration on the second signal, and transmitting the second signal in the downlink BWP group. Optionally, it is considered that the scheduling information of the first signal may also be transmitted in the downlink BWP group.

The first signal and the second signal may be uplink signals or downlink signals at the same time, or the first signal may be an uplink signal and the second signal may be a downlink signal, or the first signal may be a downlink signal and the second signal may be an uplink signal.

Designing four: determining scheduling types from configuration

For a BWP group, when configuring resources for a signal transmitted in the BWP group, it may be determined according to the configuration whether the scheduling type of the signal is cross BWP group scheduling (design one) or BWP group self-contained scheduling (design two).

When the BWP packet is designed as a BWP packet design one, for a BWP group, the first signal may be transmitted in the BWP group, and when the resource configuration is performed on the first signal based on the first configuration, it is considered that the scheduling information of the first signal may be transmitted in BWPs outside the BWP group; based on the second configuration, when the resource configuration is performed on the first signal, the scheduling information that is considered as the first signal is transmitted in the BWP group. Optionally, based on the first configuration, it is considered that the scheduling information of the first signal may also be transmitted in the BWP group.

When the BWP packet is designed as a BWP packet design two, for an uplink BWP group, the first signal may be transmitted in the uplink BWP group, and when the resource configuration is performed on the first signal based on the first configuration, it is considered that the scheduling information of the first signal may be transmitted in BWPs other than the downlink BWP group corresponding to the uplink BWP group; based on the second configuration, when performing resource allocation on the first signal, it is considered that the scheduling information of the first signal is transmitted in the downlink BWP group corresponding to the uplink BWP group. Optionally, based on the first configuration, it is considered that the scheduling information of the first signal may also be transmitted in the downlink BWP group corresponding to the uplink BWP group.

When the BWP packet is designed as BWP packet design two, for a downlink BWP group, the first signal may be transmitted in the downlink BWP group, and when the resource configuration is performed on the first signal based on the first configuration, it is considered that the scheduling information of the first signal may be transmitted in BWPs outside the downlink BWP group; based on the second configuration, when the resource configuration is performed on the first signal, the first signal is considered to be transmitted in the downlink BWP group. Optionally, based on the first configuration, it is considered that the scheduling information of the first signal may also be transmitted in the downlink BWP group.

The present embodiment provides a first resource configuration method shown in fig. 2, which may correspond to the cross-BWP group scheduling described in design one.

In step 201, the base station sends scheduling information of a first signal to the UE through the first BWP group, where the scheduling information of the first signal is used to indicate transmission resources of the first signal, and the transmission resources of the first signal are included in the second BWP group.

In step 202, the UE receives scheduling information of a first signal through a first BWP group.

The UE may determine a transmission resource of the first signal according to the scheduling information of the first signal, and the UE and the base station transmit the first signal according to the transmission resource. In the embodiment of the present application, the signals transmitted between the base station and the UE may be various possible signals. For example, the signal transmitted between the base station and the UE may be a PDSCH, a PUSCH, a synchronization signal, a downlink reference signal, a PDCCH, a PRACH, a PUCCH, or an uplink reference signal.

In the embodiment of the application, the transmission may be that the base station sends data to the UE, and the UE receives the data sent by the base station; the transmission may also be such that the UE transmits data to the base station and the base station receives data transmitted by the UE. If the signal is a downlink signal, the transmission resource of the signal may be a resource for the base station to transmit the signal, that is, a resource for the UE to receive the signal; if the signal is an uplink signal, the transmission resource of the signal may be a resource for the UE to transmit the signal, i.e., a resource for the base station to receive the signal.

The method can be applied to BWP packet design one or BWP packet design two.

When the method is used for BWP packet design one, the second BWP group may be supported differently from the first BWP group. Further, it is also possible to support that the second BWP group is the same as the first BWP group. In the embodiment of the present application, the difference between one BWP group and another BWP group may include: one BWP or BWPs included in the one BWP group are not included in the other BWP group, or one BWP or BWPs included in the other BWP group are not included in the one BWP group. When the second BWP group and the first BWP group are supported to be the same, the BWP used for transmitting the scheduling information of the first signal and the BWP where the transmission resource of the first signal is located may be the same or different, and the application is not limited thereto.

When the method is used for BWP packet design two, when the first signal is an upstream signal, the second BWP group is an upstream BWP group, and the first BWP group is a downstream BWP group, the downstream BWP groups corresponding to the first BWP group and the second BWP group may be supported to be different, and further, the downstream BWP groups corresponding to the first BWP group and the second BWP group may also be supported to be the same. When the first signal is a downlink signal, the second BWP group is a downlink BWP group, and the first BWP group is a downlink BWP group, the first BWP group and the second BWP group may be supported to be different, and further, the first BWP group and the second BWP group may be supported to be the same. When the downlink BWP groups supporting the first BWP group and the second BWP group are the same, or when the first BWP group and the second BWP group are the same, the BWP for transmitting the scheduling information of the first signal and the BWP where the transmission resource of the first signal is located may be the same or different, which is not limited in this application.

The base station may transmit scheduling information of a first signal for the UE through a first BWP in the first BWP group. Accordingly, the UE receives scheduling information of the first signal through the first BWP in the first BWP group. Optionally, the first BWP is included in M active BWPs of the UE, where the M active BWPs are included in one cell or one carrier of the UE. The M active BWPs may be included in one or more BWP groups or one or more downstream BWP groups. Wherein M is an integer greater than or equal to 1.

The transmission resources of the first signal may be included in a second BWP, which is one or more BWPs in a second BWP group.

The base station may indicate the second BWP for the UE through the scheduling information of the first signal, which may be further described as that the second BWP may be one or more BWPs indicated for the UE by the base station through the scheduling information of the first signal.

In the embodiment of the present application, the BWP groups may be numbered to obtain an index corresponding to each BWP group.

In the embodiment of the present application, when the design of the BWP packet is BWP packet design one, N configured for the UE_BWPThe BWPs may be configured or represented as N^GA BWP group, can passThe bit information indicates an index of the BWP group. Wherein N is_BWPAnd N^GIs an integer greater than or equal to 0. For example, as shown in table 1, the UE is configured with 2 BWP groups, BWP group a and BWP group B, and the indices of BWP group a and BWP group B are 0 and 1, respectively. Further, it is also possible to passThe bit information and the greater than or equal to 1-bit padding bit indicate an index of the BWP group.

TABLE 1

		BWP group A	0
BWP group B	1

In the embodiment of the present application, when the design of BWP packet is BWP packet design two, N configured for UE_BWPThe BWPs may be configured or represented as N^GA BWP group, wherein N^GEach BWP group includingAn upstream BWP group andand (4) a downlink BWP group. Wherein N is^G、Andis an integer greater than or equal to 0. The BWP groups may be numbered by any one of the following BWP group number design one and BWP group number design two.

In BWP group numbering scheme one, the data may be encoded byThe bit information indicates an index of the BWP group. For example, as shown in Table 2, the UE is configured uplinkThe BWP groups a and B are 4 BWP groups, and the BWP groups C and D are numbered, where the indices of the BWP group a, the BWP group B, the BWP group C, and the BWP group D may be 00, 01, 10, and 11. In a possible implementation, the indexes of the upstream BWP group a, the upstream BWP group B, the downstream BWP group C and the downstream BWP group D may also be 10, 11, 00 and 01, or 00, 10, 01 and 11, or 01, 11, 00 and 10, respectively, or other possibilities, which are not limited in this application. Further, it is also possible to passThe bit information and the greater than or equal to 1-bit padding bit indicate an index of the BWP group.

BWP group	Indexing
		Upstream BWP group A	00
Upstream BWP group B	01

Downstream BWP group D	11

In BWP group numbering scheme two, the data may be passedBit informationThe information indicates the index of the upstream BWP group, which can be determined byThe bit information indicates an index of the downstream BWP group. For example, as shown in table 3, the UE is configured with 4 BWP groups, namely, an uplink BWP group a and an uplink BWP group B, and the downlink BWP group C and the downlink BWP group D, and when numbering the BWP groups of the UE, the indexes of the uplink BWP group a and the uplink BWP group B are 0 and 1, respectively, and the indexes of the downlink BWP group C and the downlink BWP group D are 0 and 1, respectively. Further, it is also possible to passBit information and a padding bit greater than or equal to 1 bit indicates an index of the upstream BWP group; can also pass throughThe bit information and the padding bit of 1 bit or more indicate an index of the downstream BWP group.

		Downlink BWP group C	0
Downstream BWP group D	1

In the embodiment of the present application, when the design of the BWP packet is BWP packet design two, the BWP group pair may be numbered.

Alternatively, when one upstream BWP group can be paired with one downstream BWP group, the upstream BWP group and the downstream BWP group having the same index can be paired. The scheme can also be described as: for a BWP group pair, the BWP group pair includes an uplink BWP group and a downlink BWP group, the index of the uplink BWP group is the same as the index of the downlink BWP group, and the index of the BWP group pair is the same as the index of the uplink BWP or the index of the downlink BWP. The implicit pairing method can save the signaling overhead when configuring the BWP group. In this case, an index of the BWP group pair may be defined as an index of the upstream BWP group or an index of the downstream BWP group. In the embodiment of the present application, the BWP group pairing may also be referred to as BWP group pairing.

Alternatively, when an uplink BWP group can be paired with a downlink BWP group, the uplink BWP group and the downlink BWP group can be paired through configuration signaling sent by the base station. In the embodiment of the present application, pairing an upstream BWP group and a downstream BWP group may be further described as: the BWP group pair includes an upstream BWP group and a downstream BWP group. The explicit pairing method can re-pair the BWP group without re-pairing the BWP group, and has higher flexibility. In this case, the base station may also indicate an index of the BWP group pair.

In the embodiment of the present application, BWPs of a UE may be numbered, where the numbering of uplink BWPs and the numbering of downlink BWPs may be independent.

In the embodiment of the present application, when numbering BWPs of a UE, in one possible implementation, the BWPs may be numbered jointly between groups to obtain an index of each BWP.

In the embodiment of the present application, when the design of the BWP packet is one for the BWP packet design, N configured for the UE_BWPIn a BWP includesAn upstream BWP anda downstream BWP, can passThe bit information indicates an index of the upstream BWP, which may be provided byThe bit information indicates an index of the downstream BWP. Wherein,andis an integer greater than or equal to 0. For example, as shown in table 4, the uplink BWP a, the uplink BWP B, the downlink BWP C, and the downlink BWP D of the UE are configured into 2 BWP groups, where the BWP group a includes the uplink BWP a and the downlink BWP C, the BWP group B includes the uplink BWP B and the downlink BWP D, and the BWP index obtained by numbering the BWPs of the UE may be: the indices of the upstream BWP a and upstream BWP B are 0 and 1, respectively, and the indices of the downstream BWP C and downstream BWP D are 0 and 1, respectively. In a possible implementation, another possible BWP numbering manner is that the indexes of the upstream BWP a and the upstream BWP B are 0 and 1, respectively, and the indexes of the downstream BWP C and the downstream BWP D are 1 and 0, respectively, or other manners, which is not limited in this application. Further, it is also possible to passThe bit information and the padding bit greater than or equal to 1 bit indicate an index of the upstream BWP; can also pass throughThe bit information and the padding bit of 1 bit or more indicate an index of the downlink BWP.

Further, it is also possible to passThe bit information and the padding bit greater than or equal to 1 bit indicate an index of the upstream BWP; can also pass throughThe bit information and the padding bit of 1 bit or more indicate an index of the downlink BWP.

For example, when a first BWP group number is designed, for example, as shown in table 5, uplink BWP a and uplink BWP B of the UE are configured into 2 uplink BWP groups, where the uplink BWP group a includes the uplink BWP a, and the uplink BWP group B includes the uplink BWP B; the downlink BWP C and the downlink BWP D are configured into 2 downlink BWP groups, where the downlink BWP group C includes the downlink BWP C, and the downlink BWP group D includes the downlink BWP D. The BWP index numbering the BWPs of the UE may be: the indices of the upstream BWP a and upstream BWP B are 0 and 1, respectively, and the indices of the downstream BWP C and downstream BWP D are 0 and 1, respectively. In a possible implementation, another possible BWP numbering manner is that the indexes of the upstream BWP a and the upstream BWP B are 0 and 1, respectively, and the indexes of the downstream BWP C and the downstream BWP D are 1 and 0, respectively, or other manners, which is not limited in this application.

Upstream BWP group B	01	Upstream BWP B	1
				Downlink BWP group C	10	Downstream BWP C	0
Downstream BWP group D	11	Downlink BWP D	1

Further exemplarily, when designing a second corresponding BWP group number, for example, as shown in table 6, uplink BWP a and uplink BWP B of the UE are configured into 2 uplink BWP groups, where the uplink BWP group a includes the uplink BWP a, and the uplink BWP group B includes the uplink BWPB; the downlink BWP C and the downlink BWP D are configured into 2 downlink BWP groups, where the downlink BWP group C includes the downlink BWP C, and the downlink BWP group D includes the downlink BWP D. The index numbering the BWPs of the UE may be: the indexes of the upstream BWP a and the upstream BWPB are 0 and 1, respectively, and the indexes of the downstream BWP C and the downstream BWP D are 0 and 1, respectively. In a possible implementation, another possible BWP numbering manner is that the indexes of the uplink BWP a and the uplink BWP B are 0 and 1, respectively, and the indexes of the downlink BWP C and the downlink BWPD are 1 and 0, respectively, or other manners, which is not limited in this application.

In this embodiment of the application, when one or more upstream BWPs can be paired with one or more downstream BWPs, it can also be described that BWP pairs can be configured, the method is applicable to any one of the foregoing BWP numbering modes, and BWP pairs can be numbered.

In the embodiment of the present application, optionally, for a BWP pair, when the BWP pair includes one or more upstream BWPs and one or more downstream BWPs, the index of the one or more upstream BWPs is the same, the index of the one or more downstream BWPs is the same, the index of the one or more upstream BWPs is the same as the index of the one or more downstream BWPs, and the index of the upstream BWP in the BWP pair is the same as the index of the downstream BWP in the BWP pair. Further, the one or more upstream BWPs and the one or more downstream BWPs are in the same BWP group, or the upstream BWP group in which the one or more upstream BWPs are located and the downstream BWP group in which the one or more downstream BWPs are located may be paired BWP groups. Further, the index of a BWP pair may be defined as the index of an upstream BWP in the BWP pair or the index of a downstream BWP in the BWP pair. Illustratively, when BWPs are inter-group joint numbered, the BWP pairs are also inter-group joint numbered; when BWPs are independently numbered within a group, BWP pairs are also independently numbered within a group.

In this embodiment of the present application, optionally, the base station may indicate the BWP pair for the UE through signaling; the UE may determine a BWP pair according to signaling sent by the base station, where the BWP pair may include one or more uplink BWPs and one or more downlink BWPs. The explicit pairing method can re-pair the BWP without re-pairing the BWP, and has higher flexibility. The base station may indicate the index of the BWP in the BWP pair and may also indicate the index of the BWP pair for the UE. The BWP pairs may be jointly numbered between groups or independently numbered within groups. When the base station indicates the index of the BWP in the BWP pair, the index of the BWP may be indicated, and the index of the BWP group where the BWP is located may also be indicated. When the base station indicates the index of the BWP pair, the index of the BWP pair may be indicated, and the index of the BWP pair and the index of the BWP group corresponding to the BWP pair may also be indicated.

Several examples of possible BWP pair numbering are given below, and based on the BWP packet design, BWP group numbering design, and BWP numbering design, the description of other examples of possible BWP pair numbering will not be repeated.

Illustratively, for example, in table 10, the uplink BWP a, the uplink BWP B, the uplink BWP C, the uplink BWP D, the downlink BWP E, the downlink BWP F, the downlink BWP G, and the downlink BWP H of the UE are configured into 2 BWP groups, where the BWP group a includes the uplink BWP a, the uplink BWP B, the downlink BWP E, and the downlink BWP F, and the BWP group B includes the uplink BWP C, the uplink BWP D, the downlink BWPG, and the downlink BWP H, and the index obtained by numbering the BWPs of the UE is: the indexes of the uplink BWP A, the uplink BWP B, the uplink BWP C and the uplink BWP D are 00, 01, 10 and 11 respectively, and the indexes of the downlink BWP E, the downlink BWP F, the downlink BWP G and the downlink BWP H are 00, 01, 10 and 11 respectively; the upstream BWP and the downstream BWP having the same index are paired, and the index of the BWP pair is defined as the index of the upstream BWP or the index of the downstream BWP. Specifically, the upstream BWP a and the downstream BWP E are paired to form a BWP pair a with an index of 00, the upstream BWP B and the downstream BWP F are paired to form a BWP pair B with an index of 01, the upstream BWP C and the downstream BWP G are paired to form a BWP pair C with an index of 10, and the upstream BWP D and the downstream BWP H are paired to form a BWP pair D with an index of 11.

Watch 10

Further exemplarily, for example, in table 11, the uplink BWP a, the uplink BWP B, the uplink BWP C, the uplink BWP D, the downlink BWP E, the downlink BWP F, the downlink BWP G, and the downlink BWP H of the UE are configured into 2 BWP groups, where the BWP group a includes the uplink BWP a, the uplink BWP B, the downlink BWP E, and the downlink BWP F, and the BWP group B includes the uplink BWP C, the uplink BWP D, the downlink BWPG, and the downlink BWP H, and the index obtained by numbering the BWPs of the UE is: the indexes of the uplink BWP A and the uplink BWP B are respectively 0 and 1, the indexes of the uplink BWP C and the uplink BWP D are respectively 0 and 1, the indexes of the downlink BWP E and the downlink BWP F are respectively 0 and 1, and the indexes of the downlink BWP G and the downlink BWP H are respectively 0 and 1; the upstream BWP and the downstream BWP having the same index are paired, and the index of the BWP pair is defined as the index of the upstream BWP or the index of the downstream BWP. Specifically, the upstream BWP a and the downstream BWP E are paired to form a BWP pair a with an index of 0, the upstream BWP B and the downstream BWP F are paired to form a BWP pair B with an index of 1, the upstream BWP C and the downstream BWP G are paired to form a BWP pair C with an index of 0, and the upstream BWP D and the downstream BWP H are paired to form a BWP pair D with an index of 1.

TABLE 11

In the embodiment of the present application, when the base station indicates BWP for the UE, an index of the BWP may be indicated. After receiving the indication, the UE may determine the indicated BWP, and may also determine the BWP group in which the BWP is located. This scheme may be applicable to designs where inter-group joint numbering is performed on BWP of the UE.

In the embodiment of the present application, when the base station indicates the second BWP for the UE, the index of the second BWP may be indicated. For example, when the second BWP is X BWPs, the base station indicates the index of the X BWPs for the UE. Wherein X is an integer. Illustratively, if the first information is an uplink signal, when the base station indicates the second BWP for the UE, the configuration of the UE is as shown in table 4 or table 5, and if the index of the second BWP indicated by the base station for the UE is 0, the UE may determine that the second BWP is an uplink BWP a after receiving the index of the second BWP; if the index of the second BWP indicated by the base station for the UE is 1, the UE may determine that the second BWP is the uplink BWP B after receiving the index of the second BWP. Further illustratively, if the first information is a downlink signal, when the base station indicates a second BWP for the UE, and the BWP configured for the UE is the BWP in table 4 or table 5, if the index of the second BWP indicated by the base station for the UE is 0, the UE may determine that the second BWP is the downlink BWP C after receiving the index of the second BWP; if the index of the second BWP indicated by the base station for the UE is 1, the UE may determine that the second BWP is the downlink BWP D after receiving the index of the second BWP. In the embodiment of the present application, when the second BWP is replaced with another BWP in the method, the method may be further extended to indicate, by the base station, an index of the other BWP for the UE.

In the embodiment of the present application, when the base station indicates BWP for the UE, the base station may also indicate an index of a BWP pair in which the BWP is located. After receiving the indication, the UE may determine the BWP pair, may also determine the indicated BWP, and may also determine the BWP group in which the BWP is located. The scheme may be applicable to designs where the BWP pair for the UE is inter-group joint numbering.

In this embodiment, when the base station indicates the second BWP for the UE, the base station may indicate an index of the BWP pair where the second BWP is located. Optionally, the BWP pair to the UE in this case is inter-group joint numbered. For example, when the configuration of the UE is as shown in table 10, when the first information is an uplink signal, the base station may indicate, by 00, the BWP pair where the second BWP is located as BWP pair a for the UE, and after receiving the indication, the UE may determine that the second BWP is the uplink BWP a; when the first information is a downlink signal, the base station may indicate, by 00, the BWP pair in which the second BWP is located as BWP pair a for the UE, and the UE may determine that the second BWP is the downlink BWP E after receiving the indication. After receiving the information indicating the index of the BWP pair where the second BWP is located, the UE may determine the second BWP group and the second BWP according to the index. In the embodiment of the present application, when the second BWP is replaced with another BWP in the method, the method may be further extended to indicate, by the base station, an index of the BWP pair where the other BWP is located for the UE.

In the embodiment of the present application, when the base station indicates BWP for the UE, the base station may also indicate an index of the BWP and an index of a BWP group where the BWP is located. This scheme may be applicable to designs where BWP for UEs is independently numbered within a group. Further, when the BWP group number is the BWP group number design two, if the first information is an uplink signal, the BWP group is an uplink BWP group; if the first information is a downlink signal, the BWP group is a downlink BWP group. Illustratively, when the base station indicates the second BWP for the UE, the index of the second BWP and the index of the BWP group in which the second BWP is located may be indicated.

In the embodiment of the present application, when the base station indicates the second BWP for the UE, the index of the second BWP group and the index of the second BWP may be indicated. For example, when the configuration of the UE is as shown in table 8, when the first information is an uplink signal, the base station may indicate the UE that the second BWP group is the uplink BWP group a by 00, and indicate the uplink BWP a in the uplink BWP group a as the second BWP by 0; when the first information is a downlink signal, the base station may indicate that the second BWP group is the downlink BWP group C by 10, and indicate that the downlink BWP E in the downlink BWP group C is the second BWP for the UE by 0. After receiving the information indicating the index of the second BWP group and the index of the second BWP, the UE may determine the second BWP group and the second BWP according to the indexes. In the embodiment of the present application, when the second BWP is replaced with another BWP in the method, the method may be further extended to indicate, by the base station, an index of the other BWP for the UE; when the second BWP group is replaced with another BWP group in the method, the method may be further extended such that the base station indicates the index of the other BWP group to the UE.

In the embodiment of the present application, when the base station indicates BWP for the UE, the base station may also indicate an index of a BWP pair where the BWP is located and an index of a BWP group where the BWP is located. Upon receiving the indication, the UE may determine the BWP group and BWP in which the BWP is located. This scheme may be applicable to designs where BWP for UEs is independently numbered within a group. Further, when the BWP group number is the BWP group number design two, if the first information is an uplink signal, the BWP group is an uplink BWP group; if the first information is a downlink signal, the BWP group is a downlink BWP group.

In this embodiment, when the base station indicates the second BWP for the UE, the index of the second BWP group and the index of the BWP pair where the second BWP is located may be indicated. For example, as shown in table 11, when the first information is an uplink signal, the base station may indicate, by 0, that the second BWP group is BWP group a for the UE, and indicate, by 0, that the BWP pair where the second BWP is located is BWP pair a in the BWP group a, and then the UE may determine that the second BWP is the uplink BWP a; when the first information is a downlink signal, the base station may indicate, by 0, that the second BWP group is BWP group a for the UE, and indicate, by 0, that the BWP pair where the second BWP is located is BWP pair a in the BWP group a, and then the UE may determine that the second BWP is downlink BWP E. After receiving the information indicating the index of the second BWP group and the index of the BWP pair where the second BWP is located, the UE may determine the second BWP group and the second BWP according to the indexes. In this embodiment of the present application, when replacing the second BWP with another BWP, the method may further be extended to indicate, by the base station, an index of a BWP pair where the another BWP is located for the UE; when the second BWP group is replaced with another BWP group in the method, the method may be further extended such that the base station indicates the index of the other BWP group to the UE.

In this embodiment, when the base station indicates the BWP for the UE, the base station may also indicate an index of the BWP and an index of a BWP group pair corresponding to the BWP group where the BWP is located. After receiving the indication, the UE may determine the BWP group in which the BWP is located and the BWP. This scheme may be applicable to designs where BWP for UEs is independently numbered within a group. The index of the BWP group pair may be determined according to the paired upstream BWP group index or downstream BWP group index.

In this embodiment, when the base station indicates the second BWP for the UE, the base station may indicate an index of a BWP group pair in which the second BWP group is located and an index of the second BWP. For example, as shown in table 9, if the index of the BWP group pair is determined according to the uplink BWP group index or the downlink BWP group index of the pair, the BWP group pair a includes an uplink BWP group a and a downlink BWP group C, and the index is 0. When the first information is an uplink signal, the base station may indicate, by 0, the second BWP group to the UE as an uplink BWP group a in the BWP group pairing a, and indicate, by 0, the uplink BWP a in the uplink BWP group a as the second BWP; when the first information is a downlink signal, the base station may indicate the second BWP group to the UE through 0 as the downlink BWP group C in the BWP group pair, and indicate the downlink BWP E in the downlink BWP group C to the UE through 0 as the second BWP. After receiving the information indicating the index of the BWP group pair where the second BWP group is located and the index of the second BWP, the UE may determine the second BWP group and the second BWP according to the indexes. In the embodiment of the present application, when the second BWP is replaced with another BWP in the method, the method may be further extended to indicate, by the base station, an index of the other BWP for the UE; when the second BWP group is replaced with another BWP group in the method, the method may be further extended to indicate, by the base station, an index of the BWP group pair where the other BWP group is located to the UE.

In this embodiment, when the base station indicates the BWP for the UE, the base station may also indicate an index of a BWP pair where the BWP is located and an index of a BWP group pair corresponding to the BWP group where the BWP is located. After receiving the indication, the UE may determine the BWP group in which the BWP is located and the BWP. This scheme may be applicable to designs where BWP for UEs is independently numbered within a group.

In this embodiment, when the base station indicates the second BWP for the UE, the base station may indicate an index of a BWP group pair in which the second BWP group is located and an index of a BWP pair in which the second BWP is located. For example, as shown in table 12, if the index of the BWP group pair is determined according to the uplink BWP group index or the downlink BWP group index of the pair, the BWP group pair a includes an uplink BWP group a and a downlink BWP group C, and the index is 0. When the first information is an uplink signal, the base station may indicate, by 0, the second BWP group to the UE as an uplink BWP group a in the BWP group pairing a, and indicate, by 0, that the BWP pair where the second BWP is located is a BWP pair a in the uplink BWP group a, and then the UE may determine that the second BWP is the uplink BWP a; when the first information is a downlink signal, the base station may indicate, by 0, the UE that the second BWP group is a downlink BWP group C in the BWP group pairing a, and indicate, by 0, that the BWP pair where the second BWP is located is a BWP pair a in the downlink BWP group C, and then the UE may determine that the second BWP is a downlink BWP E. After receiving the information indicating the index of the BWP group pair where the second BWP group is located and the index of the BWP pair where the second BWP is located, the UE may determine the second BWP group and the second BWP according to the indexes. In this embodiment, when the second BWP is replaced with another BWP, the method may further be extended to indicate, by the base station, an index of the BWP pair where the other BWP is located for the UE; when the second BWP group is replaced with another BWP group in the method, the method may be further extended to indicate, by the base station, an index of the BWP group pair where the other BWP group is located to the UE.

TABLE 12

Optionally, the second BWP may also be an active BWP of the second BWP group.

The active BWP of the second BWP group may be pre-configured or indicated by the base station to the UE through signaling. The signaling may be RRC signaling or scheduling information of the first signal, and the like, and the application is not limited thereto. The active BWP of the second BWP group may be the first active upstream BWP of the second BWP group, the first active downstream BWP of the second BWP group, the upstream BWP in the first active BWP pair in the second BWP group, or the downstream BWP in the first active BWP pair in the second BWP group.

In this design, the base station may indicate the second BWP group for the UE, and the UE considers the active BWP in the second BWP group as the second BWP after receiving the indication. When the base station indicates the second BWP group for the UE, the base station may indicate the BWP group pair in which the second BWP group is located, or may indicate the second BWP group. Illustratively, when the first signal is an upstream signal, the second BWP is the first active upstream BWP in the second BWP group. The scheduling information of the first signal may be signaling for BWP configuration activation for granularity. The base station indicates, to the UE, the BWP group pairing in which the second BWP group is located through the scheduling information of the first signal, which is equivalent to activating the BWP group pairing. After receiving the scheduling information of the first signal, the UE considers the first active uplink BWP in the second BWP group as the second BWP.

Illustratively, when the first signal is an upstream signal, the second BWP is an upstream BWP in the first active BWP pair in the second BWP group. The scheduling information of the first signal may be signaling for BWP configuration activation of granularity. The base station indicates, to the UE, the BWP group pairing in which the second BWP group is located through the scheduling information of the first signal, which is equivalent to activating the BWP group pairing. After receiving the scheduling information of the first signal, the UE considers the uplink BWP in the first active BWP pair in the second BWP group as the second BWP.

Illustratively, when the first signal is a downstream signal, the second BWP is the first active downstream BWP in the second BWP group. The scheduling information of the first signal may be activation signaling for BWP configuration versus granularity. After the base station indicates the second BWP group to the UE through the scheduling information of the first signal, it is equivalent to activating the second BWP group. After receiving the scheduling information of the first signal, the UE considers the first active downlink BWP in the second BWP group as the second BWP.

Illustratively, when the first signal is a downstream signal, the second BWP is a downstream BWP in the first active BWP pair in the second BWP group. The scheduling information of the first signal may be activation signaling for BWP configuration versus granularity. And the base station indicates the BWP group pairing of the second BWP group to the UE through the scheduling information of the first signal, and then is equivalent to activating the BWP group pairing. After receiving the scheduling information of the first signal, the UE considers the downlink BWP in the first active BWP pair in the second BWP group as the second BWP.

In the embodiment of the present application, the signaling transmitted between the base station and the UE may be higher layer signaling or physical layer signaling. The higher layer signaling may be Radio Resource Control (RRC) signaling, broadcast messages, system messages, or Medium Access Control (MAC) Control Elements (CEs). The physical layer signaling may be signaling carried by a physical control channel or signaling carried by a physical data channel, where the physical control channel may be a PDCCH, an Enhanced Physical Downlink Control Channel (EPDCCH), a Narrowband Physical Downlink Control Channel (NPDCCH), or a machine type communication physical downlink control channel (MTC) physical downlink control channel (MPDCCH). The signaling carried by the PDCCH or EPDCCH may also be referred to as Downlink Control Information (DCI). The physical control channel may also be a physical sidelink control channel (physical sidelink control channel), and signaling carried by the physical sidelink control channel may also be referred to as Sidelink Control Information (SCI).

Optionally, the first signal is a PRACH, and the scheduling information of the first signal is included in a PDCCH order (order). In this embodiment, the PRACH may be a channel sent by the UE to the base station, and is used for the UE to access the base station or for the UE and the base station to implement uplink synchronization. The base station can trigger the UE to initiate random access through the PDCCH order, and the UE sends the PRACH to the base station after receiving the PDCCH order. The PDCCH order is used to trigger the UE to initiate random access, or to trigger the UE to send PRACH to the base station, which may also be referred to as another name. The PDCCH order may be included in DCI, for example, in LTE the PDCCH order is included in DCI format 1A, and in NR the PDCCH order may be included in DCI format 1_ 0.

By supporting scheduling of the PRACH across BWP, more access resources can be provided for the UE, so that the success rate of accessing the base station by the UE can be improved.

Optionally, the first signal is a Sounding Reference Signal (SRS), and the scheduling information of the first signal is included in the DCI or the MAC CE. Exemplarily, in NR, DCI including scheduling information of SRS may be DCI format 0_1 or DCI format 1_ 1.

In the embodiment of the present application, the SRS may be an uplink reference signal transmitted by the UE to the base station, and is used for measuring or estimating an uplink channel. The MAC CE may include control information of the MAC layer. The scheduling information of the SRS may include an SRS request for requesting transmission of the SRS. Illustratively, the base station transmits an SRS request for the UE, and the UE receives the SRS request and transmits the SRS to the base station.

The embodiment of the present application provides a second resource configuration method shown in fig. 3, which may correspond to the BWP group self-contained scheduling described in design two.

Step 301, the base station sends scheduling information of a second signal to the UE through the first BWP group, where the scheduling information of the second signal is used to indicate transmission resources of the second signal, and the transmission resources of the second signal are included in the first BWP group or an uplink BWP group corresponding to the first BWP group.

In step 302, the UE receives scheduling information of the second signal through the first BWP group.

The UE may determine transmission resources of the second signal according to the scheduling information of the second signal. The UE and the base station transmit a second signal according to the transmission resource.

The method can be applied to BWP packet design one or BWP packet design two.

When the method is used for BWP packet design one, the transmission resources of the second signal are included in the first BWP group.

When the method is used for BWP packet design two, when the second signal is an uplink signal, the first BWP group is a downlink BWP group, and the transmission resource of the second signal is included in the uplink BWP group corresponding to the first BWP group. When the method is used for BWP packet design two, when the second signal is a downlink signal, the first BWP group is a downlink BWP group, and the transmission resource of the second signal is included in the first BWP group.

The base station may transmit scheduling information of the second signal for the UE through a third BWP in the first BWP group. Accordingly, the UE receives the scheduling information of the first signal through the third BWP in the first BWP group. Optionally, the third BWP is included in M active BWPs of the UE, where the M active BWPs are included in one cell or one carrier of the UE. The M active BWPs may be included in one or more BWP groups or in one or more downlink BWP groups, where M is an integer greater than or equal to 1. In the present application, BWPs for transmitting scheduling information of different signals may be the same or different, and the present application is not limited thereto. For example, the second signal in the method is not the same as the first signal in the method of fig. 2, and the third BWP in the method may be the same as or different from the first BWP in the method of fig. 2, which is not limited in this application.

The transmission resource of the second signal may be included in a fourth BWP, which is the first BWP group or one or more BWPs in the upstream BWP group to which the first BWP group corresponds. When the fourth BWP is the BWP in the first BWP group, the fourth BWP may be the same as or different from the third BWP, and the application is not limited thereto.

The base station may indicate the fourth BWP for the UE through the scheduling information of the second signal, which may be further described as that the fourth BWP may be one or more BWPs indicated for the UE by the base station through the scheduling information of the second signal.

The method for indicating the fourth BWP for the UE by the base station is similar to the method for indicating the second BWP for the UE in the method related to fig. 2, and is not repeated here. The fourth BWP is similar to the second BWP, and the BWP group where the fourth BWP is located is similar to the BWP group where the second BWP is located. For example, when the base station indicates the fourth BWP for the UE, the index of the fourth BWP and the index of the first BWP group may be indicated, or the index of the fourth BWP and the index of the uplink BWP group corresponding to the first BWP group may be indicated; an index of the fourth BWP may also be indicated. By the method, the same indication format can be designed for cross-BWP group scheduling and BWP group self-contained scheduling, for example, the same DCI format is designed, and when the UE performs blind detection on the DCI, because the blind detection times of the UE are related to the type of the DCI format, the design can reduce the blind detection times when the UE retrieves the DCI, thereby saving the power consumption of the UE.

Further, in contrast to the method in which the base station indicates the second BWP for the UE in the method of fig. 2, the base station may not indicate the BWP group index or the BWP group pair index when indicating the fourth BWP for the UE. For example, the index indicating the BWP group where the fourth BWP is located may not be used, or the index indicating the downlink BWP group corresponding to the uplink BWP group where the fourth BWP is located may not be used, or the index indicating the uplink BWP group corresponding to the downlink BWP group where the fourth BWP is located may not be used.

In this design, since the UE may determine the first BWP group or determine the index of the uplink BWP group corresponding to the first BWP group after the first BWP group receives the scheduling information of the second signal, it is not necessary to indicate the first BWP group or the index of the uplink BWP group corresponding to the first BWP group through the scheduling information of the second signal.

For example, as shown in table 4, the configuration of the UE may be that the base station may send scheduling information of a second signal to the UE through a third BWP in the first BWP group, and when the second signal is an uplink signal, if the third BWP is a downlink BWP C, and if the base station indicates that an index of a fourth BWP is 0 for the UE, the UE may determine that the fourth BWP is an uplink BWP a after receiving the scheduling information of the second signal; when the second signal is an uplink signal, if the third BWP is a downlink BWP D, and if the base station indicates to the UE that the index of the fourth BWP is 1, the UE may determine that the fourth BWP is an uplink BWP B after receiving the scheduling information of the second signal; when the second signal is a downlink signal, if the third BWP is the downlink BWP C, and if the base station indicates that the fourth BWP index is 0 for the UE, the UE may determine that the fourth BWP is the downlink BWP C after receiving the scheduling information of the second signal; when the second signal is a downlink signal, if the third BWP is a downlink BWP D, if the base station indicates that the fourth BWP index is 1 for the UE, the UE may determine that the fourth BWP is the downlink BWP D after receiving the scheduling information of the second signal.

For example, the configuration of the UE is shown in table 8, assuming that the uplink BWP packet a and the downlink BWP packet C are paired or correspond. The base station may transmit scheduling information of the second signal for the UE through a third BWP in the first BWP group. When the second signal is an uplink signal, if the third BWP is a downlink BWP E, if the base station indicates that the index of the fourth BWP is 0 for the UE, the UE may determine that the fourth BWP is an uplink BWP a in the uplink BWP packet a after receiving the scheduling information of the second signal; if the base station indicates the index of the fourth BWP to be 1 for the UE, after receiving the scheduling information of the second signal, the UE may determine that the fourth BWP is the uplink BWP B in the uplink BWP packet a; when the second information is a downlink signal, if the third BWP is the downlink BWP E, if the base station indicates the UE that the index of the fourth BWP is 0, the UE may determine that the fourth BWP is the downlink BWP E in the downlink BWP packet C after receiving the scheduling information of the second signal, and if the base station indicates the index of the fourth BWP is 1, the UE may determine that the fourth BWP is the uplink BWP F in the downlink BWP packet C after receiving the scheduling information of the second signal. After receiving the information indicating the index of the BWP, the UE may determine the index of the indicated BWP, and thus may determine the BWP according to the index.

In the embodiment of the present application, when the base station indicates the fourth BWP for the UE, the base station may indicate an index of a BWP pair where the fourth BWP is located. For example, as shown in table 10, when the second signal is an uplink signal, the base station indicates, to the UE, that the index of the BWP pair where the fourth BWP is located is 00 through the scheduling information of the second signal, and after receiving the scheduling signal of the second signal, the UE may determine that the BWP pair where the fourth BWP is located is BWP pair a, so as to determine that the fourth BWP is the uplink BWP a; when the second signal is a downlink signal, the base station indicates, to the UE, through the scheduling information of the second signal, that the index of the BWP pair where the fourth BWP is located is 00, and after receiving the scheduling signal of the second signal, the UE may determine that the BWP pair where the fourth BWP is located is BWP pair a, so that the fourth BWP may be determined to be downlink BWP E.

Optionally, the fourth BWP may also be the first BWP group or the active BWP of the upstream BWP group corresponding to the first BWP group.

The active BWP of the first BWP group or the active BWP of the uplink BWP group corresponding to the first BWP group may be preconfigured or indicated by the base station to the UE through signaling. The signaling may be RRC signaling or scheduling information of the first signal, and the like, and the application is not limited thereto.

The active BWP of the first BWP group may be a first active upstream BWP of the first BWP group, a first active downstream BWP of the first BWP group, an upstream BWP of a first active BWP pair in the first BWP group, or a downstream BWP of a first active BWP pair in the first BWP group. The active BWP of the upstream BWP group to which the first BWP group corresponds may be the first active upstream BWP in the upstream BWP group to which the first BWP group corresponds.

Illustratively, when the second signal is an upstream signal, the first BWP group is a downstream BWP group, and the fourth BWP is a first active upstream BWP in the upstream BWP group to which the first BWP group corresponds. The first active uplink BWP in the uplink BWP group corresponding to the first BWP group may be a BWP configured by the base station for the UE through signaling. The base station indicates the index of the first activated uplink BWP in the uplink BWP group corresponding to the first BWP group to the UE through the scheduling information of the second signal, which is equivalent to the base station indicating the index of the fourth BWP to the UE through the scheduling information of the second signal.

When the base station indicates, through other signaling, the UE with the index of the first activated uplink BWP in the uplink BWP group corresponding to the first BWP group, where the other signaling is different from the signaling used to carry the scheduling information of the second signal, and the base station may indicate, through the scheduling information of the second signal, the index of the uplink BWP group corresponding to the first BWP group for the UE, or may not indicate the index of the uplink BWP group corresponding to the first BWP group. When the base station indicates the index of the uplink BWP group corresponding to the first BWP group to the UE through the scheduling information of the second signal, the base station may design the same indication format for the cross-BWP group scheduling and the BWP group self-contained scheduling, so the number of blind detections when the UE retrieves DCI may be reduced, thereby saving the power consumption of the UE. When the base station does not indicate the index of the uplink BWP group corresponding to the first BWP group, similar to the above description, the signaling overhead can be saved because the UE receives the scheduling information of the second information to determine the uplink BWP group corresponding to the first BWP group.

When the second signal is a downlink signal, the fourth BWP is the first active downlink BWP in the first BWP group. The first active downlink BWP in the first BWP group may be a BWP configured by the base station for the UE through signaling. The base station indicates the first activated downlink BWP in the first BWP group for the UE through the scheduling information of the second signal, which is equivalent to the base station indicating the index of the fourth BWP for the UE through the scheduling information of the second signal.

When the base station indicates the index of the first activated downlink BWP in the first BWP group to the UE through other signaling, the other signaling is different from the signaling used to carry the scheduling information of the second signal, and the base station may indicate the index of the first BWP group to the UE through the scheduling information of the second signal, or may not indicate the index of the first BWP group through the scheduling information of the second signal. When the base station indicates the index of the first BWP group to the UE through the scheduling information of the second signal, the same indication format may be designed for cross-BWP group scheduling and BWP group self-contained scheduling, so the number of blind detections when the UE retrieves DCI may be reduced, thereby saving power consumption of the UE. When the base station does not indicate the index of the first BWP group, similar to the above description, the signaling overhead can be saved because the UE receives the scheduling information of the second information to determine the uplink BWP group corresponding to the first BWP group.

The present embodiments provide a third resource configuration method, which may correspond to the scheduling of the first signal across BWP groups + the BWP group self-contained scheduling of the second signal described in design three. In the third resource allocation method, the scheduling across the BWP group for the first signal is similar to the scheduling for the first signal in the first resource allocation method related to fig. 2, and the BWP group self-contained scheduling for the second signal is similar to the scheduling for the second signal in the second resource allocation method related to fig. 3, which is not described herein again.

Optionally, the first signal is a PRACH, and the second signal is a PDSCH or a PUSCH; or the first signal is SRS and the second signal is PDSCH or PUSCH.

The embodiment of the present application provides a fourth resource allocation method, which may correspond to determining the scheduling type according to the configuration described in design four.

For a third signal, if the configuration for the signal is a first configuration, the resource configuration method for the third signal is scheduling across BWP groups; for the third signal, if the configuration for the signal is the second configuration, the resource configuration method for the third signal is BWP group self-contained scheduling. When the resource allocation method for the third signal is scheduling across BWP groups, the scheduling for the first signal in the first resource allocation method related to fig. 2 is applied to the scheduling for the third signal, or the first signal in the first resource allocation method related to fig. 2 is replaced by the third signal. When the resource allocation method for the third signal is BWP group self-contained scheduling, the scheduling for the second signal in the second resource allocation method according to fig. 5 is applied to the scheduling for the third signal, or the second signal in the second resource allocation method according to fig. 5 is replaced with the third signal.

Alternatively, the third signal may be a PRACH, and the scheduling information of the third signal may be a PDCCH order. The PDCCH order may be included in DCI. Alternatively, the third signal may be an SRS, and scheduling information of the third signal may be included in the DCI.

Designing one based on the BWP packet, when a channel for carrying scheduling information of the third signal or information including the scheduling information of the third signal is configured to be transmittable in an arbitrary BWP group of the UE; or designing two based on the BWP packet, when a channel for carrying scheduling information of the third signal or information including the scheduling information of the third signal is configured to be able to be sent in any downlink BWP group of the UE, the resource configuration method for the third signal is BWP group self-contained scheduling, and the self-contained scheduling for the third signal is similar to the scheduling for the second signal in the second resource configuration method related to fig. 3, which is not described herein again.

Designing one based on the BWP packet when the channel for carrying the scheduling information of the third signal or the information including the scheduling information of the third signal is configured to be N_y1When the third signal is transmitted in the BWP groups, the resource configuration method for the third signal is BWP group self-contained scheduling, that is, the UE may transmit the third signal in the BWP group configured with the channel carrying the scheduling information of the third signal, or the UE may transmit the third signal in the BWP group configured with the information including the scheduling information of the third signal; or the resource configuration method of the third signal is cross BWP group scheduling; or the base station configures a first BWP group and a second BWP group of the UE, the resource configuration method for the third signal in the first BWP group is BWP group self-contained scheduling, and the resource configuration method for the third signal in the second BWP group is cross-BWP group scheduling. The scheduling of the third signal across the BWP group is similar to the scheduling of the first signal in the first resource configuration method related to fig. 2, and is not described herein again. When the resource configuration method for the third signal in the second BWP-like group is scheduling across BWP groups, for one BWP group in the second BWP-like group, the scheduling information of the third signal of the BWP group is transmitted in other BWP groups except the BWP group; or a BWP group in the second BWP-like group, for a BWP in the BWP group, the third signal of the BWPIs transmitted in BWP groups other than the BWP group. Wherein N is_y1Greater than or equal to 1 and less than the number of BWP groups of the UE.

Based on BWP packet design two, when the channel for carrying the scheduling information of the third signal or the information including the scheduling information of the third signal is configured to be N_y1When the third signal is transmitted in the downlink BWP group, the resource configuration method for the third signal is BWP group self-contained scheduling, that is, the UE may transmit the third signal in the downlink BWP group configured with the channel carrying the scheduling information of the third signal, or the UE may transmit the third signal in the downlink BWP group configured with the information including the scheduling information of the third signal; or the resource configuration method of the third signal is cross BWP group scheduling; or the base station configures a first type downlink BWP group and a second type downlink BWP group of the UE for the UE, the resource configuration method for the third signal in the first type downlink BWP group is BWP group self-contained scheduling, and the resource configuration method for the third signal in the second type downlink BWP group is cross-BWP group scheduling. The scheduling of the third signal across the BWP group is similar to the scheduling of the first signal in the first resource configuration method related to fig. 2, and is not described herein again. When the resource configuration method for the third signal in the second type downlink BWP group is scheduling across BWP groups, for one downlink BWP group in the second type downlink BWP group, the scheduling information of the third signal of the uplink BWP group corresponding to the downlink BWP group is transmitted in other downlink BWP groups except the downlink BWP group; or for one downlink BWP group in the second type of downlink BWP group, for one uplink BWP in the uplink BWP group corresponding to the downlink BWP group, the scheduling information of the third signal of the uplink BWP is transmitted in other downlink BWP groups except the downlink BWP group. Wherein N is_y1Greater than or equal to 1 and less than the number of downlink BWP groups of the UE.

Optionally, the third signal is an SRS, scheduling information of the SRS is included in the MAC CE, and a resource configuration manner of the SR is BWP group self-contained scheduling.

In a wireless communication system, after a base station transmits data to a UE through a PDSCH, the UE may feed back Acknowledgement (ACK)/Negative Acknowledgement (NACK) to the base station according to whether the data is successfully received, where ACK indicates that the data is correctly received, and NACK indicates that the data is not correctly received. The base station may retransmit the data for the UE after receiving the NACK. How to perform ACK/NACK feedback is also a worthy topic of study in scenarios that allow simultaneous activation of multiple BWPs.

The embodiment of the application also provides a transmission method of the ACK/NACK feedback. In this method, the UE sends ACK/NACK feedback for signal a, which is a signal transmitted in BWP group B, to the base station in BWP group a. Wherein BWP group a may also be referred to as xth BWP group or other name, BWP group B may also be referred to as yth BWP group or other name, signal a may also be referred to as zth signal or other name, X, Y and Z may be one, two, three, four, five or other positive integers. In the method, the raw materials are mixed,

in one possible implementation, signal a is a signal carried by the PDSCH and the ACK/NACK feedback of signal a is carried by the PUSCH or PUCCH.

The method can be applied to BWP packet design one or BWP packet design two.

When the method is used for BWP packet design one, BWP group a and BWP group B may be supported differently. Further, it is also possible to support BWP group a and BWP group B to be the same.

When the method is used for BWP group design two, the BWP group A is an upstream BWP group, and the BWP group B is a downstream BWP group. It may be supported that the upstream BWP groups corresponding to BWP group a and BWP group B are different. Further, it may also support that the upstream BWP groups corresponding to BWP group a and BWP group B are the same.

The ACK/NACK feedback for signal a may be transmitted in one BWP in BWP group a.

The signal a may be transmitted in one or more BWPs in the BWP group B.

Illustratively, the base station transmits PDSCH, carrying signal a, to the UE in one or more BWPs in BWP group B. Accordingly, the UE receives the PDSCH in the corresponding BWP. If the UE correctly receives the signal A carried in the PDSCH, the UE feeds back ACK corresponding to the signal A to the base station; and if the UE does not correctly receive the signal A carried in the PDSCH, the UE feeds back NACK corresponding to the signal A to the base station. When the UE feeds back the ACK/NACK of the signal A to the base station, the ACK/NACK is fed back to the base station in one BWP of the uplink BWP group A.

In a wireless communication system, a UE may receive a signal B sent by a base station, and is used for performing downlink path loss estimation, Radio Resource Management (RRM) measurement, or time-frequency tracking and the like on the UE and the base station, where the time-frequency tracking includes time-domain synchronization and/or frequency-domain synchronization. Illustratively, one or more BWPs are included in serving cell a, which may be mapped to serving cell B. When the UE performs downlink path loss estimation, RRM measurement, or time-frequency tracking for the BWP in the serving cell a, the UE receives the signal B of the serving cell B, and performs downlink path loss estimation, RRM measurement, or time-frequency tracking according to the signal B.

Further, when a plurality of signals B are included in the serving cell B, a signal B corresponding to each BWP in the serving cell a may be independently configured for the BWP in the serving cell a, and the signal B corresponding to each BWP in the serving cell a is the signal B in the serving cell B. The signals B corresponding to different BWPs in the serving cell a may be the same or different, and the application is not limited thereto. When a UE performs downlink loss estimation, RRM measurement, or time-frequency tracking on a BWP in a serving cell a, the UE receives a signal B corresponding to the BWP and performs downlink loss estimation, RRM measurement, or time-frequency tracking according to the signal B.

In the above method, all BWPs in the serving cell a are mapped to the signal B of the same serving cell. In a scenario allowing simultaneous activation of multiple BWPs, it is worth to study how to improve the accuracy of downlink path loss estimation, RRM measurement, or time-frequency tracking.

In the first signal transmission method provided in the embodiment of the present application, when the method is applied to a cell level, a base station transmits a signal B of a serving cell B, where the signal B is used to perform downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to a BWP group a1 in the serving cell a; the base station transmits a signal B of the serving cell C, which is used for performing downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the BWP group a2 in the serving cell a. Correspondingly, the UE receives the signal B of the serving cell B, and performs downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the BWP group a1 in the serving cell a according to the signal B of the serving cell B; the UE receives the signal B of the serving cell C, and performs downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the BWP group a2 in the serving cell a according to the signal B of the serving cell C. The serving cell B may also be referred to as a serving cell corresponding to the BWP group a1, or a serving cell linked (link) in the BWP group a 1; serving cell C may also be referred to as a serving cell corresponding to BWP group a2, or a serving cell linked by BWP group a 2.

In the first signal transmission method provided in the embodiment of the present application, when the method is applied to a carrier level, for example, a base station sends a signal B of a carrier B, where the signal B is used to perform downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to a BWP group a1 in the carrier a; the base station sends a signal B of a carrier C, and the signal B is used for downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the BWP group a2 in the carrier a. Correspondingly, the UE receives the signal B of the carrier B, and performs downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the BWP group a1 in the carrier a according to the signal B of the carrier B; and the UE receives the signal B of the carrier C, and performs downlink path loss estimation, RRM measurement or time-frequency tracking corresponding to the BWP group A2 in the carrier A according to the signal B of the carrier C. The carrier B may also be referred to as a carrier corresponding to the BWP group a1, or a carrier linked (link) in the BWP group a 1; carrier C may also be referred to as a carrier to which BWP group a2 corresponds, or a carrier to which BWP group a2 links.

In the following description, for simplicity of description, a carrier level method and a cell level method may be described by being combined in the form of "serving cell/carrier".

In the method, corresponding service cells/carriers are independently configured for different BWP groups of a service cell/carrier a, the service cells/carriers corresponding to the different BWP groups may be the same or different, and are used for performing downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to each BWP group, which may improve the accuracy of downlink path loss estimation, RRM measurement, or time-frequency tracking, thereby ensuring the quality of downlink data transmission and improving the downlink data transmission rate. For example, when the signal B is not configured in the serving cell/carrier a and the carrier corresponding to the serving cell/carrier a is a large bandwidth carrier, if the distance between the BWP group a1 and the BWP group a2 in the frequency domain is long, the time domain and/or the frequency domain of the BWP group a1 and the BWP group a2 are not synchronous, or the channel conditions of the BWP group a1 and the BWP group a2 are different, and when the BWP a1 and the BWP a2 correspond to the same serving cell/carrier, the accuracy of downlink loss estimation, RRM measurement, or time-frequency tracking may not be high, and the quality of downlink data transmission cannot be guaranteed.

In the method, further, for a BWP group of the serving cell/carrier a, the BWP group may also correspond to the serving cell a/carrier.

In the method, the correspondence between the BWP group and the serving cell/carrier, the serving cell/carrier corresponding to the BWP group, or the BWP group corresponding to the serving cell/carrier may be indicated to the UE by the base station through signaling.

Further, for one BWP group in the serving cell/carrier a, its corresponding signal B may be configured independently for the BWPs in the BWP group.

Illustratively, the base station transmits a signal B1 of serving cell/carrier B, where the signal B1 is used to perform downlink loss estimation, RRM measurement, or time-frequency tracking corresponding to the first BWP of BWP group a 1; accordingly, the UE receives the signal B1 of serving cell/carrier B, and performs downlink loss estimation, RRM measurement, or time-frequency tracking corresponding to the first BWP of BWP group a1 according to the signal B1. The base station sends a signal B2 of a serving cell/carrier B, where the signal B2 is used to perform downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the second BWP of the BWP group a 1; accordingly, the UE receives the signal B2 of serving cell/carrier B, and performs downlink loss estimation, RRM measurement, or time-frequency tracking corresponding to the second BWP of BWP group a1 according to the signal B1. The base station sends a signal b3 of a serving cell/carrier C, where the signal b3 is used to perform downlink loss estimation, RRM measurement, or time-frequency tracking corresponding to the first BWP of the BWP group a 2; accordingly, the UE receives the signal b3 of the serving cell/carrier C, and performs downlink loss estimation, RRM measurement, or time-frequency tracking corresponding to the first BWP of the BWP group a2 according to the signal b 3. The base station sends a signal b4 of serving cell/carrier C, where the signal b4 is used to perform downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the second BWP of BWP group a 2; accordingly, the UE receives the signal b4 of the serving cell/carrier C, and performs downlink loss estimation, RRM measurement, or time-frequency tracking corresponding to the second BWP of the BWP group a2 according to the signal b 4.

In the method, the correspondence between BWP and signal B, signal B corresponding to BWP, or BWP corresponding to signal B may be indicated to the UE by the base station through signaling.

In the method, in the serving cell/carrier corresponding to the BWP group, the corresponding signal B may be further configured for different BWPs in the BWP group independently, and the signal B corresponding to different BWPs may be the same or different, so that the accuracy of downlink loss estimation, RRM measurement, or time-frequency tracking is used when the distance between different BWPs in the BWP group is relatively long.

Alternatively, the signal B may be a Synchronization Signal (SS), a demodulation reference signal (DMRS), a CSI-RS, or a Tracking Reference Signal (TRS).

In the second signal transmission method provided in the embodiment of the present application, when the method is applied to a cell level, a base station sends a first signal B to a UE, where the first signal B is used to perform downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to a BWP group a1 of a serving cell a; the base station sends a second signal B for performing downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the BWP group a2 of the serving cell a. Correspondingly, the UE receives the first signal B, and performs downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the BWP group a1 of the serving cell a according to the first signal B; and the UE receives the second signal B, and performs downlink path loss estimation, RRM measurement or time-frequency tracking corresponding to the BWP group A2 of the serving cell A according to the second signal B. The first signal B may also be referred to as a signal B corresponding to BWP group a1, or a signal B linked (link) to BWP group a 1; the second signal B may be referred to as a signal B corresponding to the BWP group a2, or a signal B linked with the BWP group a 2.

In the second signal transmission method provided in the embodiment of the present application, when the method is applied to a carrier level, a base station sends a first signal B to a UE, where the first signal B is used to perform downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to a BWP group a1 of a carrier a; the base station sends a second signal B for performing downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the BWP group a2 of the carrier a. Correspondingly, the UE receives the first signal B, and performs downlink path loss estimation, RRM measurement, or time-frequency tracking corresponding to the BWP group a1 of the carrier a according to the first signal B; and the UE receives the second signal B, and performs downlink path loss estimation, RRM measurement or time-frequency tracking corresponding to the BWP group A2 of the carrier A according to the second signal B. The first signal B may also be referred to as a signal B corresponding to BWP group a1, or a signal B linked (link) to BWP group a 1; the second signal B may be referred to as a signal B corresponding to the BWP group a2, or a signal B linked with the BWP group a 2.

In the method, corresponding signals B are independently configured for different BWP groups of a serving cell/carrier A, the signals B corresponding to the different BWP groups may be the same or different, and are used for performing downlink path loss estimation, RRM measurement or time-frequency tracking corresponding to each BWP group, and the accuracy of the downlink path loss estimation, RRM measurement or time-frequency tracking can be improved, so that the quality of downlink data transmission is ensured, and the downlink data transmission rate is improved. This method differs from the first method of transmission of synchronization signals in that in this method the BWP group no longer corresponds to the serving cell/carrier, which directly corresponds to the specific signal B.

In the method, the BWP group and signal B correspondence, the signal B corresponding to the BWP group, or the BWP group corresponding to the signal B may be indicated to the UE by the base station through signaling.

Alternatively, signal B may be a synchronization signal, DMRS, CSI-RS, or TRS.

Optionally, the signal B is a synchronization signal, and for one BWP group, the base station may indicate, to the UE, a grid or an absolute frequency point number where the synchronization signal or SSB corresponding to the BWP group is located.

Optionally, the signal B is DMRS, CSI-RS or TRS, and for one BWP group, the base station may indicate, for the UE, a resource grid corresponding to the signal B corresponding to the BWP group. In this embodiment, Resource Elements (REs) for transmitting the signal B may be configured in a resource grid corresponding to the signal B.

Optionally, the signal B is DMRS, CSI-RS or TRS, and for one BWP group, the base station may indicate, for the UE, an offset of the resource grid corresponding to the signal B corresponding to the BWP group from the resource grid corresponding to the BWP group. Wherein the Offset may be Offset subcarriers; the offset may also be an integer number of RBs or RBGs; the Offset may also be an integer number of RBs or RBGs, and Offset subcarriers. Wherein Offset may be an integer less than or equal to 11.

Optionally, the signal B is DMRS, CSI-RS, or TRS, and for a BWP group, the resource grid corresponding to the signal B corresponding to the BWP group is the resource grid corresponding to the BWP group. For the serving cell/carrier a, the resource grids corresponding to different BWP groups may be configured independently, and the resource grids corresponding to different BWP groups may be the same or different, which is not limited in this application. For example, for a BWP group of serving cell/carrier a, the base station may configure a point a corresponding to the BWP group for the UE, where the point a is used to determine a resource grid corresponding to the BWP group; correspondingly, the UE receives point a corresponding to the BWP group configured by the base station, and determines the resource grid corresponding to the BWP group according to the point a. The resource grid corresponding to the BWP may be a resource grid corresponding to a carrier where the BWP is located.

In the embodiment of the present application, the introduction of the resource grid, point a, and the method for determining the resource grid according to point a may refer to the corresponding introduction in NR protocol 38.211. For example, in a version 15.1.0 of the NR protocol 38.211, reference may be made to the corresponding description in section 4 for the introduction of the resource grid.

In this embodiment of the present application, the base station may further independently configure the first signal B of the serving cell B for the BWP group in the first BWP group of the serving cell/carrier a through a first signal transmission method, and independently configure the second signal B for the BWP group in the second BWP group of the serving cell/carrier a through a second signal transmission method, which is the same as the above specific implementation manner and is not described herein again. The first BWP-like group may include one or more BWP groups, and the second BWP-like group may include one or more BWP groups.
