The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0048] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

[0049] As people pursue higher speed, latency, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3rd Generation Partnership Project (3GPP) international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC).

[0050] On the one hand, eMBB still aims at users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc.

[0051] In the early days of NR deployment, complete NR coverage was difficult to obtain, so the typical network coverage was wide-area LTE coverage and NR island coverage. In addition, a large number of LTEs are deployed below 6GHz, and there is little spectrum below 6GHz available for 5G. Therefore, NR must study spectrum applications above 6GHz, but high-frequency bands have limited coverage and fast signal fading. At the same time, in order to protect mobile operators' early investments in LTE, a tight interworking working mode between LTE and NR was proposed.

[0052] In 5G, the maximum channel bandwidth can be 400MHZ (called a wideband carrier). Compared with the maximum 20M bandwidth of LTE, the bandwidth of a wideband carrier is very large. If the terminal device continues to work on a wideband carrier, the power consumption of the terminal device will be very large. Therefore, it is recommended that the radio frequency (RF) bandwidth of the terminal device can be adjusted according to the actual throughput of the terminal device. For this reason, the concept of BWP is introduced. The motivation of BWP is to optimize the power consumption of the terminal device. For example, if the rate of the terminal device is very low, a smaller BWP can be configured for the terminal device (such as Figure 2-1 If the terminal device has a high rate requirement, a larger BWP can be configured for the terminal device (such as Figure 2-2 If the terminal device supports high speed or works in carrier aggregation (CA) mode, multiple BWPs can be configured for the terminal device (such as Figure 2-3 Another purpose of BWP is to trigger the coexistence of multiple numerologies in a cell, such as Figure 2-3 As shown, BWP1 corresponds to numerology1, and BWP2 corresponds to numerology2.

[0053] A terminal can be configured with up to 4 uplink BWPs and up to 4 downlink BWPs through dedicated signaling of Radio Resource Control (RRC), but only one uplink BWP and downlink BWP can be activated at the same time. In the RRC dedicated signaling, the first activated BWP among the configured BWPs can be indicated. At the same time, when the terminal is in the connected state, it can also switch between different BWPs through downlink control information (DCI). When a carrier in an inactive state enters an activated state, the first activated BWP is the first activated BWP configured in the RRC dedicated signaling. The configuration parameters of each BWP include:

[0054] - Subcarrier Spacing;

[0055] -cyclicPrefix;

[0056] -The first physical resource block (PRB) of the BWP and the number of consecutive PRBs (locationAndBandwidth);

[0057] -BWP identification (bwp-Id);

[0058] -BWP common configuration parameters and dedicated configuration parameters (bwp-Common, bwp-Dedicated).

[0059] When performing Radio Link Monitor (RLM), the terminal only performs it on the activated BWP. No operation is required on the inactive BWP. When switching between different BWPs, there is no need to reset the RLM-related timers and counters. For RRM measurement, no matter which activated BWP the terminal sends or receives data on, it does not affect the RRM measurement. For CQI measurement, the terminal only needs to perform it on the activated BWP.

[0060] When a carrier is deactivated and then activated through a Media Access Control Control Element (MAC CE), the initial first activated BWP is the first activated BWP configured in the RRC dedicated signaling.

[0061] The value of the BWP identifier (BWP id) in the RRC dedicated signaling is 0 to 4, and the BWP with a BWP identifier of 0 is the initial BWP by default.

[0062] In DCI, the BWP indicator is 2 bits, as shown in Table 1. If the number of configured BWPs is less than or equal to 3, BWP indicator = 1, 2, 3 correspond to BWP id = 1, 2, 3 respectively. If the number of BWPs is 4, BWP indicator = 0, 1, 2, 3 correspond to the BWPs configured according to the sequential index.

[0063] Moreover, the network side uses consecutive BWP ids when configuring BWP.

[0064]

[0065] Table 1

[0066] In order to meet the demand for high rates, 5G also supports CA technology. CA enables the NR system to support a larger bandwidth by jointly scheduling and using resources on multiple component carriers (CCs), thereby achieving a higher system peak rate. According to the continuity of the aggregated carriers in the spectrum, it can be divided into continuous carrier aggregation and non-continuous carrier aggregation; according to whether the bandwidth (band) of the aggregated carriers is the same, it can be divided into intra-band carrier aggregation and inter-band carrier aggregation.

[0067] In CA, there is only one primary carrier (Primary Cell Component, PCC), which provides RRC signaling connection, non-access stratum (NAS) function, security function, etc. The physical uplink control channel (Physical Uplink Control Channel, PUCCH) is on the PCC and only exists on the PCC. The secondary carrier (Secondary Cell Component, SCC) only provides additional wireless resources. PCC and SCC are collectively referred to as service cells, where the cell on the PCC is the primary cell (Primary cell, Pcell) and the cell on the SCC is the Scell. The standard also stipulates that a maximum of 5 aggregated carriers are supported, that is, the maximum bandwidth after aggregation is 100MHZ, and the aggregated carriers belong to the same base station. All aggregated carriers use the same cell radio network temporary identifier (Cell-Radio Network Temporary Identifier, C-RNTI), and the base station implements to ensure that the C-RNTI does not conflict in the cell where each carrier is located. Since both asymmetric carrier aggregation and symmetric carrier aggregation are supported, it is required that the aggregated carrier must have downlink and may not have uplink. Moreover, for a PCC cell, there must be a PDCCH and PUCCH of the cell, and only the primary carrier cell has a PUCCH, while other secondary carrier cells may have a PDCCH.

[0068] Scell ​​is configured through RRC dedicated signaling, and the initial configuration state is in an inactive state, in which data cannot be sent or received. Then the Scell ​​is activated through MAC CE to send and receive data. From the perspective of the delay of Scell ​​configuration and activation, this architecture is not an optimal architecture. This delay reduces the efficiency of CA use and wireless resources, especially in small cell deployment scenarios. In dense small cell deployment scenarios, the signaling load of each Scell ​​is also very large, especially when each Scell ​​needs to be configured separately. Therefore, the current CA architecture introduces additional delays, limits the use of CA, and reduces the gain of CA load sharing.

[0069] To this end, LTE R15 optimizes CA. The main optimization functions are as follows: 1) The Scell ​​state is divided into an active state and an inactive state. In order to achieve fast cell recovery, a new cell state is defined, namely the dormant state. In the dormant state, the terminal measures and reports CQI / RRM, but does not decode PDCCH. At the same time, a new MAC CE is defined to control the transition between the active state and the dormant state, such as Figure 3-1 and Figure 3-2 As shown, among which, Figure 3-1 In the MAC CE, 1 byte is included to control the state transition of 7 cells. Figure 3-2 In the MAC CE, 4 bytes are included to control the status of 31 cells, where Ci represents the status of the cell with index number i. When Ci is set to 1, it means that the cell with index number i is in dormant state, and when Ci is set to 0, it means that the cell with index number i is in active state. 2) In the RRC signaling, the state of the Scell ​​can be configured as active state or dormant state, and the default state is inactive state.

[0070] In order to quickly restore the Scell ​​and transmit data as quickly as possible, a mechanism similar to the dormant state needs to be introduced. However, the dormant state mechanism of LTE is too complicated, and MAC CE needs to be introduced to perform the state transition of the Scell. To this end, it is possible to consider configuring a concept called dormant BWP (dormant BWP) for the Scell. When the traffic volume is not large, some Scell ​​BWPs can be switched to dormant BWPs through DCI. When the traffic volume is large, the dormant BWP of the Scell ​​is switched to the non-dormant BWP through DCI to activate the service transmission function of the cell, which has a shorter activation delay and lower complexity than the traditional Scell ​​dormant state activation.

[0071] In NR, the state of the Scell ​​is directly configured as an activated state through RRC, wherein the activated state has dormancy behavior and non-dormancy behavior, that is, the dormancy behavior is part of the activated state.

[0072] In the NR R16 CA / DC enhancement topic, Scells are grouped, and the network can instruct a group of Scells to enter an activated state with sleep behavior or an activated state with non-sleep behavior through DCI commands according to the Scell ​​group. At the same time, in the R16 CA / DC enhancement topic, Scell ​​grouping can use different Scell ​​groupings according to whether the terminal device is in DRX activation time or non-DRX activation time. Therefore, the network side will configure two Scell ​​grouping configurations.

[0073] At the same time, when the terminal device receives a DCI from the network, which indicates that all Scells of a group of Scells enter an activated state with non-dormancy behavior (referred to as non-dormancy behavior) from an activated state with dormancy behavior (referred to as dormancy behavior), the network side configures a BWP as the activation BWP when the terminal device enters non-dormancy behavior (this BWP is called the first activation BWP). DCI has two application scenarios, one is receiving a dormancy / non-dormancy indication from the DCI corresponding to the wake-up signal (Wake UpSignal, WUS), and the other is receiving a dormancy / non-dormancy indication from a normal DCI. The first activation BWP in these two scenarios can be configured as different BWPs.

[0074] In R17, in order to speed up the activation of Scell, it is hoped to support the sending of Scell ​​activation and deactivation commands through DCI, which may also be activation and deactivation in the form of Scell ​​groups. Since PDCCH carries the sleep-non-sleep switching command of at least one Scell ​​or at least one group of Scells, or the activation and deactivation command of at least one Scell ​​or at least one group of Scells, PDCCH has no feedback mechanism. If the network side issues the above command but the terminal device does not receive it, the network side does not know whether the terminal device has received the DCI carrying the above command. At the same time, the dormancy / non-dormancy indication (i.e., sleep-non-sleep switching command) carried by DCI corresponding to WUS and the dormancy / non-dormancy indication (i.e., sleep-non-sleep switching command) carried by ordinary DCI may correspond to different Scell ​​groups or the same Scell ​​group. After a Scell ​​of the terminal device enters the non-dormancy behavior, the activated BWP may be different or the same in the above two DCIs. In order to save signaling overhead, only one DCI configured for two scenarios can be configured. The technical solution of the embodiment of the present application is described in detail below.

[0075] Figure 4 A flow chart of the feedback method provided in the embodiment of the present application is as follows: Figure 4 As shown, the feedback method comprises the following steps:

[0076] Step 401: A terminal device receives a DCI sent by a network device, where the DCI carries first indication information, where the first indication information is used to indicate a state of at least one group of Scells or a state of at least one Scell.

[0077] In an embodiment of the present application, a network device sends a DCI to a terminal device, and correspondingly, the terminal device receives the DCI sent by the network device. Here, optionally, the network device may be a base station, such as a gNB.

[0078] In an embodiment of the present application, the DCI carries first indication information, and the first indication information is used to indicate the state of at least one group of Scells or the state of at least one Scell. For example, the first indication information is used to indicate the state of N1 groups of Scells, where N1 is a positive integer. For example, the first indication information is used to indicate the state of N2 Scells, where N2 is a positive integer.

[0079] In the embodiment of the present application, the state is the first state or the second state.

[0080] 1) In an optional manner, the first state refers to an activated state with a dormancy behavior (abbreviated as dormancy behavior), and the second state refers to an activated state with a non-dormancy behavior (abbreviated as non-dormancy behavior). For this manner, the first indication information may be referred to as dormancy / non-dormancy indication information, or as a dormancy-non-dormancy switching command.

[0081] 2) In another optional manner, the first state refers to an activated state, and the second state refers to a deactivated state (or referred to as an inactive state). In this manner, the first indication information may be referred to as an activation / deactivation command.

[0082] In an optional manner, the first indication information includes a first bit map, each bit in the first bit map corresponds to a group of Scells or corresponds to a Scell, and the value of the bit is used to indicate whether the state of a group of Scells or the state of a Scell ​​corresponding to the bit is the first state or the second state.

[0083] For example, the first indication information carried by the DCI is implemented by a 5-bit bitmap, where the 5 bits in the bitmap correspond to 5 groups of SCells or 5 SCells, respectively, where the grouping of the SCells is configured by RRC signaling. The value of a bit is 1 or 0, indicating whether a group of SCells or an SCell corresponding to the bit enters dormancy behavior or leaves dormancy behavior (i.e., enters non-dormancy behavior).

[0084] For example, the first indication information carried by the DCI is implemented by a 5-bit bitmap, where the 5 bits in the bitmap correspond to 5 groups of SCells or 5 SCells, respectively, where the grouped RRC signaling configuration of the SCell. The value of the bit is 1 or 0, indicating whether a group of SCells or one SCell corresponding to the bit enters an activated state or leaves an activated state (i.e., enters a deactivated state).

[0085] Step 402: The terminal device sends second indication information to the network device, where the second indication information is used to indicate that the terminal device confirms receipt of the first indication information.

[0086] In the embodiment of the present application, the terminal device sends second indication information to the network device, and correspondingly, the network device receives the second indication information sent by the terminal device.

[0087] In the embodiment of the present application, the second indication information is carried in the MAC CE, or in the PUCCH, or in the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

[0088] In the embodiment of the present application, the second indication information is used to indicate that the terminal device confirms receipt of the first indication information. Further, optionally, the second indication information is also used to indicate at least one of the following:

[0089] The terminal device has successfully received the first indication information;

[0090] The time when the terminal device receives the first indication information;

[0091] The terminal device receives index information of the BWP where the first indication information is located;

[0092] The terminal device receives index information of the search space where the first indication information is located.

[0093] Here, the moment when the terminal device receives the first indication information includes at least one of the following:

[0094] The terminal device receives the SFN number of the PDCCH or DCI corresponding to the first indication information;

[0095] The terminal device receives the subframe number of the PDCCH or DCI corresponding to the first indication information;

[0096] The terminal device receives the timeslot number of the PDCCH or DCI corresponding to the first indication information;

[0097] The terminal device receives the symbol number of the PDCCH or DCI corresponding to the first indication information.

[0098] In the above solution, the first indication information corresponding to PDCCH or DCI refers to: PDCCH or DCI carrying the first indication information.

[0099] In the embodiment of the present application, the terminal device may send the second indication information to the network device in the following manner:

[0100] 1) the terminal device sends the second indication information in the first PUCCH after receiving the first indication information; or,

[0101] 2) the terminal device sends the second indication information in the first PUSCH after receiving the first indication information; or,

[0102] 3) The terminal device sends the second indication information in the first PUSCH scheduling grant after receiving the first indication information.

[0103] In an optional manner, the network device starts a timer after the first indication information is sent, and if the timer times out, the network device considers that the terminal device has not successfully received the first indication information. Further, optionally, the network device may cancel sending the first indication information.

[0104] Here, the duration of the timer may be agreed upon by the protocol or configured on the network side.

[0105] In an embodiment of the present application, the DCI received by the terminal device may be a DCI of a first format or a DCI of a second format, the DCI of the first format corresponds to one application scenario, and the DCI of the second format corresponds to another application scenario. Specifically, the DCI of the first format refers to the DCI corresponding to the WUS (i.e., the DCI used to implement the wake-up signal); the DCI of the second format refers to the DCI corresponding to the non-WUS (i.e., ordinary DCI). For the above two different formats of DCI, the associated configurations may be different or the same. The following is a detailed description.

[0106] ■The network device sends first configuration information to the terminal device, and the terminal device receives the first configuration information sent by the network device, where the first configuration information is used to determine the Scell ​​grouping configuration corresponding to the DCI in the first format and / or the Scell ​​grouping configuration corresponding to the DCI in the second format.

[0107] For example, the SCell group configuration method is shown in Table 2 below:

[0108]

[0109] Table 2

[0110] A1) If the Scell ​​grouping configuration corresponding to the DCI of the first format is not configured in the first configuration information, the Scell ​​grouping configuration corresponding to the DCI of the first format is the same as the Scell ​​grouping configuration corresponding to the DCI of the second format; or, if the Scell ​​grouping configuration corresponding to the DCI of the second format is not configured in the first configuration information, the Scell ​​grouping configuration corresponding to the DCI of the second format is the same as the Scell ​​grouping configuration corresponding to the DCI of the first format.
