In order 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.

With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of the services in future life, the third generation partnership project (3)^rdGeneration Partnership Project, 3GPP) the international organization for standardization began developing 5G. The main application scenarios of 5G are: enhanced Mobile ultra-wideband (enhanced Mobile B)roadband, eMBB), Low-Latency high-reliability Communications (URLLC), and massive Machine-Type Communications (mtc).

On the one hand, the eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said that it must be analyzed in detail in conjunction with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

When NR is deployed early, complete NR coverage is difficult to obtain, so typical network coverage is wide area LTE coverage and islanding coverage mode of NR. Moreover, a large amount of LTE is deployed below 6GHz, and the spectrum below 6GHz available for 5G is rare. NR must therefore be studied for spectrum applications above 6GHz, with limited high band coverage and fast signal fading. Meanwhile, in order to protect the early LTE investment of a mobile operator, a light interworking (TIGHT) working mode between LTE and NR is provided.

In 5G, the maximum channel bandwidth may be 400MHZ (referred to as wideband carrier), which is large compared to the LTE maximum 20M bandwidth. The power consumption of the terminal device is very large if the terminal device remains operating on the wideband carrier. It is proposed that the Radio Frequency (RF) bandwidth of the terminal device can be adjusted according to the actual throughput of the terminal device. To this end, the concept of BWP was introduced, the motivation of which was to optimize the power consumption of the end devices. For example, if the velocity of the terminal device is low, the terminal device may be configured with a slightly smaller BWP (as shown in fig. 2-1), and if the velocity requirement of the terminal device is high, the terminal device may be configured with a slightly larger BWP (as shown in fig. 2-2). If the terminal device supports high rates or operates in Carrier Aggregation (CA) mode, the terminal device may be configured with multiple BWPs (as shown in fig. 2-3). Another purpose of BWP is to trigger coexistence of multiple underlying parameter sets (numerology) in a cell, as shown in fig. 2-3, BWP1 corresponds to numerology1 and BWP2 corresponds to numerology 2.

A terminal may be configured with at most 4 uplink BWPs and at most 4 downlink BWPs through Radio Resource Control (RRC) dedicated signaling, but only one uplink BWP and one downlink BWP may be activated at the same time. In RRC dedicated signaling, a first active BWP of the configured BWPs may be indicated. Meanwhile, in the process that the terminal is in the connected state, switching between different BWPs can also be performed through Downlink Control Information (DCI). When the carrier in the inactive state enters the active state, the first active BWP is the first active BWP configured in the RRC dedicated signaling. The configuration parameters for each BWP include:

-subcarrier spacing (subarrierspating);

-a cyclic prefix (cyclic prefix);

-a first Physical Resource Block (PRB) of BWP and a number of consecutive PRBs (locationAndBandwidth);

-BWP identification (BWP-Id);

-BWP Common configuration parameters and Dedicated configuration parameters (BWP-Common, BWP-Dedicated).

The terminal only executes on the active BWP during Radio Link Monitor (RLM), the inactive BWP does not need to operate, and the timer and counter related to RLM do not need to be reset when switching between different BWPs. For Radio Resource Management (RRM) measurement, RRM measurement is not affected no matter which activated BWP the terminal receives and transmits data on. For the measurement of Channel Quality Indication (CQI), the terminal also only needs to perform on active BWP.

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

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

A BWP indicator (BWP indicator) is 2 bits (bit) in DCI, as shown in table 1 below. If the number of the configured BWPs is less than or equal to 3, the BWP indicator is 1,2 and 3 correspond to the BWP id of 1,2 and 3 respectively. If the number of the BWPs is 4, the BWP indicator is 0, and 1,2, and 3 correspond to the BWPs sequentially indexed. And the network side uses the continuous BWP id in configuring BWP.

TABLE 1

To meet the demand for high rates, CA technology is also supported in 5G. CA enables NR systems to support larger bandwidths by jointly scheduling and using resources on multiple Component Carriers (CCs), thereby enabling higher peak rates of the system. According to the continuity of the aggregated carriers on the frequency spectrum, the method can be divided into continuous carrier aggregation and non-continuous carrier aggregation; according to whether the bandwidths (bands) where the aggregated carriers are located are the same, the method is divided into Intra-band carrier aggregation and inter-band carrier aggregation.

In CA, there is only one Primary Cell Component (PCC), which provides RRC signaling connection, non-access stratum (NAS) functions, security functions, and the like. A Physical Uplink Control Channel (PUCCH) exists on the PCC and only on the PCC. The Secondary Cell Component (SCC) provides only additional radio resources. The PCC and the SCC are also referred to as serving cells, where a cell on the PCC is a Primary cell (Pcell) and a cell on the SCC is an SCell. The standard also stipulates that the aggregated carriers support at most 5, namely the aggregated maximum bandwidth is 100MHZ, and the aggregated carriers belong to the same base station. All aggregated carriers use the same Cell-Radio Network Temporary Identifier (C-RNTI), and the base station ensures that the C-RNTI does not conflict in the Cell where each carrier is located. Because the asymmetric carrier aggregation and the symmetric carrier aggregation are supported, the carriers required to be aggregated must have downlink and may not have uplink. And for the PCC cell, the PDCCH and the PUCCH of the cell are determined, only the primary carrier cell has the PUCCH, and other secondary carrier cells may have the PDCCH.

The SCell is configured through RRC dedicated signaling, and the initially configured state is an inactive state in which data transmission and reception are not possible. And then the SCell is activated through the MAC CE so as to transmit and receive data. This architecture is not an optimal architecture from the SCell configuration and activation latency point of view. This delay, in turn, reduces the efficiency of CA usage and radio resources, especially in small cell deployment scenarios. In dense small cell deployment scenarios, the signaling load of each SCell is also large, especially if each SCell needs to be configured separately. Therefore, the current CA architecture introduces extra delay, limits the use of CA, and reduces the gain of CA load sharing.

For this reason, LTE R15 optimizes CA, and the main optimization functions are as follows: 1) the states of the SCell are divided into an active state and an inactive state, and in order to achieve fast cell recovery, a new cell state, i.e., a dormant (dormant) state, is defined. In the dormant state, the terminal measures and reports CQI/RRM, but does not decode PDCCH. Meanwhile, a MAC CE is newly defined to control the transition between the active state and the dormant state, as shown in fig. 3-1 and 3-2, wherein in fig. 3-1, the MAC CE includes 1 byte to control the state transition of 7 cells, and in fig. 3-2, the MAC CE includes 4 bytes to control the state of 31 cells, wherein C_iRepresenting the state corresponding to the cell with index i, C_iSet to 1 representing a cell with index i in dormant state, C_iSetting to 0 represents that the cell with index i is in an active state. 2) In RRC signaling, the state of the SCell may be configured as an active state or a dormant state, and defaults to an inactive state.

The NR introduces a dormant (dormant) behavior and a non-dormant (non-dormant) behavior of the SCell, which respectively correspond to a dormant activated state and a non-dormant activated state, wherein the dormant activated state refers to an activated state with dormant behavior, and the non-dormant activated state refers to an activated state with non-dormant behavior. And the SCell in the dormancy activated state does not perform data transceiving action except RRM and CSI measurement. And the network side controls the SCell of one SCell group to enter a dormant activation state or enter a non-dormant activation state according to the SCell group pre-configured by the RRC through the PDCCH. Meanwhile, each SCell may also be instructed to enter into the dormant activation state or enter into the non-dormant activation state according to a bitmap (bitmap) of all scells. Here, if the SCell group is used for indication, the SCell group may be divided into at most 5 groups, that is, there are 5 bits of bitmap in the PDCCH, each bit corresponds to one SCell group, a value of the bit is set to 1 to indicate that the corresponding SCell group enters a non-dormant activation state, and a value of the bit is set to 0 to indicate that the corresponding SCell group enters a dormant activation state.

The activation state and the deactivation state of the SCell (referred to as activation and deactivation) are controlled by the MAC CE with the SCell as the granularity (per SCell), and there is a time delay defect in this way to control the activation and deactivation of the SCell. Therefore, the following technical scheme of the embodiment of the application is provided.

Fig. 4 is a flowchart illustrating a method for controlling a cell state according to an embodiment of the present application, where as shown in fig. 4, the method for controlling a cell state includes the following steps:

step 401: the terminal device receives a PDCCH, and determines whether the at least one SCell enters an activated state or a deactivated state based on the PDCCH.

In the embodiment of the application, the network device sends a PDCCH, and accordingly, the terminal device receives the PDCCH, where the PDCCH is used for determining whether the at least one SCell enters the active state or the deactivated state. It should be noted that the PDCCH is used to determine whether the state of each SCell in the at least one SCell enters an active state or a deactivated state, where the states of different scells may be the same or different.

It should be noted that the SCell in the embodiment of the present application may also be replaced with a carrier.

In this embodiment of the application, the PDCCH carries an SCell activation/deactivation command, and the SCell activation/deactivation command indicates whether at least one SCell enters an activation state or a deactivation state. The following describes in detail the technical solution of the embodiment of the present application in conjunction with a specific implementation manner of an SCell activation/deactivation command.

SCell activation deactivation command is implemented by a bitmap

The SCell activation deactivation command is used to control an activation state and/or a deactivation state of at least one SCell. Further, the command for controlling the first state and/or the second state of the at least one SCell may be referred to as an SCell sleep non-sleep command (or as a dormant and non-dormant transition command), where the first state refers to an active state with a sleep behavior (i.e., a dormant active state) and the second state refers to an active state with a non-sleep behavior (i.e., a non-dormant active state).

Both the SCell activation deactivation command and the SCell sleep non-sleep command may be implemented by a bitmap, specifically:

● for a bitmap for controlling the activation state and/or the deactivation state, each bit in the bitmap corresponds to one SCell group, and the value of the bit is used to indicate whether the SCell group corresponding to the bit enters the activation state or the deactivation state; for a bitmap for controlling the first state and/or the second state, each bit in the bitmap corresponds to one SCell group, and the value of the bit is used for indicating whether the state of the SCell group corresponding to the bit enters the first state or the second state.

Here, the network side configures SCell group configuration (SCell group configuration) in advance through RRC signaling. And determining the SCell group configuration and the number of each SCell group through the SCell group configuration. The number of bits contained in the bit map is consistent with the number of the SCell groups configured by the SCell groups, each bit in the bit map corresponds to one SCell group configured by the SCell groups, and the value of the bit is used for indicating the state of the corresponding SCell group. For example: the bit map contains 5 bits, i.e. the bit map is a 5bit bitmap, which may indicate the status of the group of 5 scells.

In the embodiment of the present application, the SCell group configuration associated with the bitmap for controlling the activation state and/or the deactivation state and the SCell group configuration associated with the bitmap for controlling the first state and/or the second state may be the same (refer to the following manner a) or different (refer to the following manner B).

A) For a bitmap for controlling an activation state and/or a deactivation state, a plurality of SCell groups associated with the bitmap are determined based on first configuration information; for a bitmap used for controlling a first state and/or a second state, a plurality of SCell groups associated with the bitmap are determined based on the first configuration information; wherein the first configuration information is used to determine a plurality of SCell groups obtained according to a first grouping formula.

Here, the first configuration information is used to determine an SCell group configuration. Further, optionally, the first configuration information is carried in RRC signaling. By the SCell grouping mode, the SCell grouping of the SCell activation and deactivation command is the same as the SCell grouping of the sleep non-sleep command.

B) For a bitmap for controlling an activation state and/or a deactivation state, a plurality of SCell groups associated with the bitmap are determined based on first configuration information; for a bitmap used for controlling the first state and/or the second state, a plurality of SCell groups associated with the bitmap are determined based on the second configuration information; the first configuration information is used for determining a plurality of SCell groups obtained according to a first grouping mode, and the second configuration information is used for determining a plurality of SCell groups obtained according to a second grouping mode.

Here, the first configuration information is used to determine a first SCell group configuration. The second configuration information is used to determine a second SCell group configuration. Further, optionally, the first configuration information and the second configuration information are carried in RRC signaling. By the SCell grouping mode, all SCells are grouped again according to the SCell activation and deactivation command, so that the SCell grouping of the SCell activation and deactivation command is different from the SCell grouping and the SCell grouping of the sleep non-sleep command.

● for a bitmap for controlling the activation state and/or the deactivation state, each bit in the bitmap corresponds to an SCell, and the value of the bit is used to indicate whether the SCell corresponding to the bit enters the activation state or the deactivation state; for a bitmap for controlling the first state and/or the second state, each bit in the bitmap corresponds to one SCell, and the value of the bit is used to indicate whether the state of the SCell corresponding to the bit enters the first state or the second state.

Here, the network side configures SCell configuration (SCells configuration) in advance through RRC signaling. Wherein the SCell configuration is used to determine one or more SCells. The number of bits contained in the bitmap is consistent with the number of scells in the SCell configuration, each bit in the bitmap corresponds to one SCell in the SCell configuration, and the value of the bit is used for indicating the state of the corresponding SCell. For example: the bitmap contains 15 bits, i.e. the bitmap is a 15-bit bitmap, which can indicate the states of 15 scells.

In the embodiment of the present application, in order to distinguish the bit map for controlling the activation state and/or the deactivation state from the bit map for controlling the first state and/or the second state, the following manner may be adopted.

The first method is as follows: the PDCCH carries a first bitmap and first indication information; the first indication information is used for indicating whether the first bitmap is a bitmap for controlling an activation state and/or a deactivation state or a bitmap for controlling a first state and/or a second state; wherein the first state refers to an active state with sleep behavior (i.e., dormancy active state), and the second state refers to an active state with non-sleep behavior (i.e., non-dormancy active state).

For example: the first indication information is realized by 1 bit, and the value of the bit is 1 (or 0), which means that a first bitmap carried by the PDCCH is a bitmap for controlling an activation state and/or a deactivation state; the value of the bit is 0 (or 1), which means that the first bitmap carried by the PDCCH is a bitmap for controlling the first state and/or the second state.

The second method comprises the following steps: the PDCCH carries a first bitmap; the terminal equipment determines whether the first bitmap is a bitmap for controlling an activation state and/or a deactivation state or a bitmap for controlling a first state and/or a second state based on the RNTI associated with the PDCCH; wherein the first state refers to an active state with dormant behavior, and the second state refers to an active state with non-dormant behavior.

Specifically, if the PDCCH is associated with a first RNTI, the terminal device determines that the first bitmap is a bitmap for controlling an activation state and/or a deactivation state; or, if the PDCCH is associated with a second RNTI, the terminal device determines that the first bitmap is a bitmap for controlling a first state and/or a second state.

Here, the network side may configure a new RNTI (i.e., the first RNTI) for the PDCCH carrying the bitmap for controlling the activation state and/or the deactivation state, and on the other hand, the PDCCH carrying the bitmap for controlling the first state and/or the second state is scrambled by an existing RNTI (i.e., the second RNTI), so that the terminal device may distinguish whether the bitmap carried by the PDCCH is the bitmap for controlling the activation state and/or the deactivation state or the bitmap for controlling the first state and/or the second state by using the RNTI.

The third method comprises the following steps: the PDCCH carries a first bit map and/or a second bit map, and the first bit map is different from the second bit map; wherein the first bitmap is a bitmap for controlling an activation state and/or a deactivation state; the second bitmap is a bitmap for controlling a first state and/or a second state, the first state being an active state with sleep behavior and the second state being an active state with non-sleep behavior.

Here, the bitmap for controlling the activation state and/or the deactivation state is distinguished from the bitmap for controlling the first state and/or the second state, that is, a bitmap (i.e., the first bitmap) is newly defined in the PDCCH, and the bitmap is the bitmap for controlling the activation state and/or the deactivation state.

SCell activation deactivation command is realized through indication information

The first method is as follows: and the SCell sends a PDCCH to the terminal equipment, the terminal equipment receives the PDCCH sent by the SCell, the PDCCH carries second indication information, and the second indication information is used for indicating the SCell to enter a deactivation state.

Here, the activation state or the deactivation state of the SCell is indicated with the SCell as granularity. The second indication information is implemented by, for example, 1 bit, and a value of the bit is 1 (or 0) to indicate that the SCell enters a deactivated state.

It should be noted that the SCell referred to in the embodiments of the present application may also be replaced with a carrier.

The second method comprises the following steps: and the SCell sends a PDCCH to the terminal equipment, the terminal equipment receives the PDCCH sent by the SCell, and the value of at least one field in the PDCCH is used for indicating the SCell to enter a deactivation state.

Here, the activation state or the deactivation state of the SCell is indicated with the SCell as granularity. The SCell may be implicitly indicated to enter a deactivated state by a special value of a certain field or fields in the PDCCH of the SCell.

The third method comprises the following steps: the terminal equipment receives the PDCCH sent by the PCell or the PSCell, the PDCCH carries third indication information, and the third indication information is used for indicating at least one SCell to enter an activated state.

Here, the third indication information includes identification information of each SCell of the at least one SCell. Further, optionally, the identification information of the SCell includes at least one of: SCell index, serving cell index, CFI.

Here, the activation state or the deactivation state of the SCell is indicated with the SCell as granularity. Third indication information for indicating an SCell that needs to be activated (enter an activated state) may be carried through a PDCCH of the PCell or the PSCell. It should be noted that the SCell in the embodiment of the present application may also be replaced with a carrier.

Further, optionally, for the third mode, the PDCCH also carries fourth indication information and/or fifth indication information;

the fourth indication information is used for indicating the first activated BWP after the SCell enters the activated state; for example, the fourth indication information carries index information of the first activated BWP after the SCell enters the activated state.

The fifth indication information is used for indicating whether the SCell enters a first state or a second state after entering an active state, wherein the first state is an active state with sleep behavior, and the second state is an active state with non-sleep behavior.

Behavior of terminal device after receiving PDCCH

Behavior 1: the terminal device determines that the designated SCell or SCell group enters a deactivated state based on the PDCCH.
