Description

Technical Field

[0001] This application relates to the field of wireless communication technology, such as a wireless communication method, a communication node, and a storage medium. Background Technology

[0002] Mobile telecommunications technologies are propelling the world toward an increasingly connected and networked society. Compared to existing wireless networks, next-generation systems and wireless communication technologies will need to support a wider range of use case characteristics and provide access to a more complex and sophisticated range of requirements and flexibility.

[0003] Long-Term Evolution (LTE) is a wireless communication standard for mobile devices and data terminals developed by the 3rd Generation Partnership Project (3GPP). LTE Advanced (LTE-A) is a wireless communication standard that enhances the LTE standard. The fifth-generation wireless system (known as 5G) advances the LTE and LTE-A wireless standards and aims to support higher data rates, massive connectivity, ultra-low latency, high reliability, and other emerging service requirements.

[0004] Wireless network systems have become a common means of communication for most people worldwide. A typical wireless communication network (e.g., employing frequency division, time division, and / or code division techniques) includes one or more base stations (typically referred to as "BS"), each providing geographic wireless coverage, and one or more wireless user equipments (typically referred to as "UEs") that can transmit and receive data within the wireless coverage area. For base stations, Cell Discontinuous Transmission (cell DTX) or Cell Discontinuous Reception (cell DRX) applies to UEs in Connected Mode of Radio Resource Control (RRC), aiming to keep the cell inactive by employing necessary signaling mechanisms, thereby achieving energy savings for the base station. During cell DTX inactivity, the base station does not transmit certain common reference signals and downlink data scheduling, and the UE does not listen to the Physical Downlink Control Channel (PDCCH) in the common search space and does not receive downlink data. During cell DRX inactivity, the base station does not schedule or receive uplink configured grants (CGs) or scheduling requests (SRs), and the UE does not transmit data during CG / SR events. When a UE is configured with multiple serving cells that support cell DTX / DRX operations, bandwidth part (BWP) handover may occur. The UE may also be unable to accurately obtain indications of cell DTX / DRX configurations for each serving cell. The base station and UE cannot clearly and uniformly define operations on each serving cell within the serving cell group, thus compromising the reliability of discontinuous cell transmission.

[0030] The present application will now be described in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0031] For the second communication node (such as a wireless transmission node, base station, or gNB), cell discontinuous transmission / cell discontinuous reception (cellDTX / cell DRX) applies to the first communication node in connected mode (RRC), such as wireless communication equipment or user equipment (UE). It aims to maintain the cell inactive state using necessary signaling mechanisms, thereby achieving base station energy saving. During cell DTX inactivity, the base station does not transmit certain common reference signals or downlink data scheduling, and the UE does not listen to the PDCCH in the common search space or receive downlink data. During cell DRX inactivity, the base station does not schedule or receive uplink CG / SR, and the UE does not transmit data during CG / SR events. The base station can configure CellDTX / DRX on a cell-by-cell basis using RRC signaling, or it can use dynamic signaling DCI format 2-9 to indicate the activation and deactivation of cell DTX / DRX configuration. The UE listens to DCI format 2-9 on only one serving cell. DCI format 2-9 contains multiple information blocks, each corresponding to one serving cell and including a 1-bit cell DTX configuration activation / deactivation indication field and / or a 1-bit cell DRX configuration activation / deactivation indication field. When the UE is configured with multiple serving cells that support cell DTX / DRX operations, the following issues arise.

[0032] Question 1: For example Figure 1 As shown, assuming the UE hears DCI format 2-9 at slot m on the first serving cell, and a block in DCI format 2-9 indicates the activation / deactivation information of the cell DTX / DRX configuration of the second serving cell, then the UE should apply this indication no earlier than slot m+d, where d = 3ms. However, if... Figure 2 As shown, if a BWP handover occurs between slot m and slot m+d in the first serving cell, and the subcarrier spacing (SCS) configurations of the two BWPs before and after the handover are different, the UE will be unable to determine whether to execute the DCI indication information no earlier than t1 (slot m+d of the BWP before the handover) or no earlier than t2 (slot m+d of the BWP after the handover). This will lead to an ambiguity in application timing between the base station and the UE. Figure 3As shown, the UE determines slot m as the time to receive DCI format 2-9 based on the SCS when carrying the PDCCH of DCI format 2-9, and determines the application delay d as x slots. If a BWP handover occurs on the first serving cell, the slot m+d time determined by the UE based on the SCS of the BWP after the handover and the SCS of the BWP before the handover will be inconsistent, and the absolute time of t1 may be earlier than t2. This results in the UE not having enough application time on the second serving cell to fully execute the indicated cell DTX / DRX operation.

[0033] Question 2: For example Figure 4 As shown, each information block in DCI format 2-9 indicates the activation / deactivation information of the cell DTX / DRX configuration of a serving cell. Therefore, when a UE is configured with multiple serving cells that support cell DTX / DRX operation, the higher-layer signaling should reasonably configure the position of each serving cell in DCI format 2-9 to ensure that the UE can accurately obtain the cell DTX / DRX configuration activation / deactivation information of each serving cell. Otherwise, it will cause a problem of inconsistent understanding between the base station and the UE.

[0034] Question 3: Cell DTX is configured per serving cell, while UE CDRX is configured per medium access control entity (MAC entity) (i.e., per serving cell group). For example... Figure 5 As shown, when both cell DTX and UE CDRX are configured simultaneously, during the UE CDRX active period (including the running periods of the UE CDRX on duration timer and inactivity timer) within the cell DTX inactive period, the UE performs UE behavior according to the rules of the cell DTX non-active period, or the UE assumes that this duration is the UE CDRX inactive period. However, since UE CDRX is configured per cell group, it is necessary to explicitly define the UE CDRX behavior of the serving cell within the entire group to ensure that the base station and the UE understand the behavior consistently across cells within the cell group.

[0035] This application aims to solve the protocol ambiguity problem in cell DTX / DRX configuration, and proposes an efficient and more flexible signaling configuration solution to ensure that the base station and UE have a consistent understanding of the behavior on the serving cell under cell DTX / DRX configuration.

[0036] Figure 6This is a flowchart illustrating a wireless communication method according to one embodiment, which can be applied to a first communication node, such as a UE. Figure 6 As shown, the method provided in this embodiment includes steps 110 and 120.

[0037] In step 110, configuration information is received.

[0038] In step 120, the DCI format is set on the active downlink BWP of the first serving cell according to the configuration information.

[0039] In one embodiment, the configuration information includes one of the following: the location information of the information block in the downlink control information (DCI), the serving cell index or identifier, the location information of the indication information corresponding to a specific serving cell in the DCI, a combination of location information, a list of location information combinations, the cell discontinuous transmission (DTX) configuration, and the cell discontinuous reception (DRX) configuration.

[0040] In one embodiment, the indication information for setting the DCI format includes indication information for at least one second serving cell's cell DTX configuration or cell DRX configuration;

[0041] The indication information of the cell DTX configuration or cell DRX configuration of the second serving cell is a single information block;

[0042] The information block is used to indicate at least one of the following:

[0043] Activate or deactivate the community's DTX configuration;

[0044] Activate or deactivate the DRX configuration in the community.

[0045] In one embodiment, the method further includes:

[0046] The configured DCI format is received in the first time slot of the activated downlink BWP on the first serving cell;

[0047] In a second time slot with a set delay no earlier than the first time slot, the corresponding operation is performed on the activated BWP on the second serving cell according to the indication information of the cell DTX configuration or cell DRX configuration in the set DCI format.

[0048] In one embodiment, the first time slot is the time slot location where the configured DCI format is received in the first serving cell, or the time slot location where the configured DCI format BWP is received in the first serving cell.

[0049] In one embodiment, the second time slot is the time slot location at which the BWP with the set DCI format is received in the first serving cell.

[0050] In one embodiment, the set delay is 3 milliseconds, or a first value is determined based on receiving the BWP in the set DCI format in the first serving cell, the first value being an integer in time slots.

[0051] In one embodiment, the method further includes:

[0052] The starting position of the indication information corresponding to the second serving cell in the DCI is determined based on the configuration information.

[0053] In one embodiment, the configuration information includes the location information of the information block in the DCI, or the serving cell index or identifier;

[0054] The location information of the information block in the DCI includes the indication information of the cell DTX configuration or cell DRX configuration of the second serving cell, and the starting position of the DCI payload in the set DCI format.

[0055] Alternatively, the location information of the information block in the DCI may be associated with the index or identifier of the second serving cell.

[0056] In one embodiment, the configuration information includes a combination of location information;

[0057] The location information combination includes the location information of the information block of the second serving cell in the DCI and the index or identifier of the second serving cell.

[0058] In one embodiment, the configuration information includes a list of combinations of location information;

[0059] The list of location information combinations satisfies at least one of the following:

[0060] The list of location information combinations includes one or more combinations of location information.

[0061] The number of location information combinations shall not exceed the total number of serving cells supported by the first communication node;

[0062] The first communication node supports serving cells including normal cells and cells that support cell DTX configuration or cell DRX configuration. Normal cells include cells that do not support cell DTX, cell DRX, or network energy saving operations.

[0063] In one embodiment, the set DCI format includes DCI formats 2-9, and the set DCI format belongs to the Type3-PDCCH public search space type.

[0064] In one embodiment, the serving cell group is configured for UE connected-mode discontinuous CDRX reception and the second serving cell in the serving cell group is configured for cell discontinuous transmission, the cell discontinuous transmission including cell DTX or cell DRX;

[0065] When the UE CDRX activation period and the cell discontinuous transmission inactivation period overlap on the second serving cell, the first communication node on the second serving cell performs UE behavior according to the UE CDRX inactivation period or according to the cell discontinuous configuration inactivation period during the overlapping period; the first communication node performs UE behavior according to the UE CDRX activation period on the third serving cell in the serving cell group, the third serving cell including cells that are configured to the first communication node that do not support cell DTX or cell DRX or do not support network power saving operation.

[0066] In one embodiment, the first communication node supports operation of at least one of UE CDRX, cell DTX, and cell DRX.

[0067] In one embodiment, the UE CDRX activation period includes either the CDRX duration timer running period or the CDRX inactivity timer running period.

[0068] In one embodiment, the UE behavior performed during the overlapping period includes at least one of the following:

[0069] Terminate the CDRX timer operation during the continuous period on the second serving cell;

[0070] Terminate the inactive CDRX timer on the second serving cell;

[0071] Listen to the PDCCH according to the definition of CDRX inactive period.

[0072] In some embodiments, the information block is used to indicate at least one of the following: cell DTX / DRX mode switching, channel state information sub-configuration resource switching, channel state information sub-configuration resource index, beam state information switching, beam or channel state information measurement resource switching, and beam or channel state information measurement resource index.

[0073] In this embodiment, to reduce the downlink transmission / uplink reception activity time of the gNB, the terminal can be configured with a periodic cell DTX / DRX mode (i.e., active and inactive periods). The cell DTX / DRX mode configuration is universal for UEs configured with this feature in the serving cell. Cell DTX and cell DRX modes can be configured and activated separately. When cell DTX is configured and activated for a relevant cell, the UE does not monitor the PDCCH during the cell DTX inactive period under certain conditions or SPS timings. When cell DRX is configured and activated for a relevant cell, the UE does not send or transmit SR within CG resources during the cell DRX inactive period. This feature only applies to UEs in the RRC_CONNECTED state and does not affect the Random Access (RA) procedure, SSB transmission, paging, and system information broadcasting. Cell DTX / DRX can be activated / deactivated via RRC signaling or layer 1 (L1) group common signaling (i.e., DCI format 2-9). The characteristics of cell DTX / DRX are as follows:

[0074] Activation period: The duration during which the UE waits to receive PDCCHs or SPS, and to send SRs or CGs. During this period, to conserve network energy, the transmission / reception of PDCCHs, SPSs, SRs, and CGs on the gNB side is unaffected.

[0075] Period: Specifies the repetition of the activation period, followed by a period of inactivity;

[0076] When both cell DTX and cell DRX are configured, the activation period and cycle parameters between cell DTX and cell DRX are common.

[0077] Once the gNB identifies an emergency call or a public safety-related service (such as MPS or MCS), the network should ensure that it does not affect that service (e.g., it may release or deactivate the cell DTX / DRX configuration). The network should also ensure that there is at least partial overlap between the UE CDRX duration and the cell DTX / DRX activity duration in connected mode; that is, the UE CDRX period in connected mode is a multiple of the cell DTX / DRX period, and vice versa.

[0078] DCI format 2-9 is used to activate or deactivate the cellDTX / DRX configuration of one or more serving cells for one or more UEs. DCI format 2-9 is scrambled by NES-RNTI and is used to transmit the following information:

[0079] Block 1, Block 2, ..., Block N

[0080] The starting position of the UE's information block is determined based on higher-layer parameters.

[0081] If the UE is configured with cell DTX and cell DRX, the UE can be configured with one or more blocks, each block containing the following indication fields:

[0082] Cell DTX / DRX indicator

[0083] If certain indication conditions are met, the indication field has 2 bits, where the most significant bit (MSB) corresponds to the cell DTX configuration and the least significant bit (LSB) corresponds to the cell DRX configuration; otherwise, the indication field has 1 bit, corresponding to either the cell DTX configuration or the cell DRX configuration.

[0084] Example 1: Application latency of activation / deactivation indication in cell DTX / DRX configuration

[0085] The UE receives a PDCCH carrying DCI format 2-9 at slot m of the active downlink bandwidth portion (active DL BWP) in the first serving cell. DCI format 2-9 indicates whether to activate or deactivate the current cell DTX or cell DRX operation in the second serving cell. The UE begins execution of the operation in a time slot of the activated downlink BWP or activated uplink BWP in the second serving cell according to the indicated cell DTX or cell DRX operation. The time slot of the activated downlink BWP or activated uplink BWP in the second serving cell satisfies the condition that it is not earlier than the start position of slot m+d of the activated downlink BWP in the first serving cell.

[0086] In some embodiments, if the UE does not perform a BWP handover during a specific period on the first serving cell, then d is set to 3ms. The values ​​of d under different SCS configurations are shown in Table 1.

[0087] Table 1 Mapping relationship between SCS and d

[0088] SCS(kHz) Number of time slots 15 3 30 6 60 12 120 24 480 96 960 192

[0089] In some embodiments, if the UE performs a BWP handover during a specific period on the first serving cell, the UE assumes that the time when the active BWP before the BWP handover receives DCI format 2-9 is slot m.

[0090] In some embodiments, d can take one of the following values: 3ms or or or or or or or or or Or max(3ms,δ). In some embodiments, the values ​​of δ are shown in Table 2.

[0091] Table 2. Parameters for BWP handover delay

[0092]

[0093]

[0094] In some embodiments, if the UE performs a BWP handover during a specific period on the first serving cell, the UE assumes that the slot closest to the time of receiving DCI format 2-9 on the active BWP after the BWP handover is slot m, or assumes that the slot on the active BWP after the BWP handover has the same slot index / identifier as the slot on the BWP before the BWP handover that received DCI format 2-9.

[0095] In some embodiments, d can take one of the following values: 3ms or or or or or or or or or Or max(3ms,δ). In some embodiments, the values ​​of δ are shown in Table 2.

[0096] In some embodiments, if the UE performs a BWP handover during a specific period on the first serving cell or the active BWP after the BWP handover is an uplink BWP, the UE assumes that the time when the active BWP before the BWP handover receives DCI format 2-9 is slot m, or the UE assumes that the slot closest to the time when the active BWP after the BWP handover receives DCI format 2-9 is slot m, or the UE assumes that the time when the active BWP after the BWP handover receives DCI format 2-9 has the same time slot index / identifier as the BWP before the BWP handover, or the UE assumes that the slot m on the BWP with the smaller SCS among the BWPs before and after the BWP handover is slot m.

[0097] In some embodiments, d may take one of the following values: 3ms or min(3ms,δ) or max(3ms,δ) or the value of d may be determined according to the smaller SCS between the SCS before BWP handover and the SCS after BWP handover.

[0098] In some embodiments, if the UE performs a BWP handover during a specific period on the first serving cell or the active BWP after the BWP handover is a downlink BWP, the UE assumes that the time when the active BWP before the BWP handover receives DCI format 2-9 is slot m, or the UE assumes that the slot closest to the time when the active BWP after the BWP handover receives DCI format 2-9 is slot m, or the UE assumes that the time when the active BWP after the BWP handover receives DCI format 2-9 has the same slot index / identifier as the BWP before the BWP handover, or the UE assumes that the slot m on the BWP with the smaller SCS among the BWPs before and after the BWP handover is slot m.

[0099] In some embodiments, d may take one of the following values: 3ms or min(3ms,δ) or max(3ms,δ) or the value of d may be determined according to the smaller SCS between the SCS before BWP handover and the SCS after BWP handover.

[0100] In some embodiments, the value of d includes one of the following: 3ms, or the SCS of the downlink active BWP before BWP handover is used as the reference SCS and the value of d is determined according to Table 1, or the SCS of the active BWP after BWP handover is used as the reference SCS and the value of d is determined according to Table 1.

[0101] In some embodiments, the specific period includes one of the following: after slot m or no earlier than slot m or earlier than slot m+d or no later than slot m+d or between slot m and slot m+d or no earlier than slot m-δ or no later than slot m+d-δ.

[0102] In some embodiments, δ is taken as the BWP switching delay (as shown in Table 2) or 10–25 ms.

[0103] In some embodiments, the BWP handover refers to the UE performing a BWP handover on the first serving cell at a time no earlier than slot m on the BWP where the PDCCH of DCI format 2-9 is received, or completing a BWP handover at a time no later than slot m+d on the BWP where the PDCCH of DCI format 2-9 is received.

[0104] In some embodiments, the UE determines the value of d according to the SCS of the active BWP after BWP handover or the currently active BWP in the first serving cell, where slot m is the slot corresponding to the SCS of the active downlink BWP in the first serving cell where the PDCCH of DCI format 2-9 is received. In some embodiments, slot m+d is the slot corresponding to the SCS of the currently active BWP or the BWP after BWP handover in the first serving cell.

[0105] In some embodiments, the UE determines d and slot m according to the SCS of the active downlink BWP where the PDCCH of DCI format 2-9 is received in the first serving cell. In some embodiments, slot m+d is the slot corresponding to the SCS of the active downlink BWP where the PDCCH of DCI format 2-9 is received in the first serving cell.

[0106] For example, the UE receives DCI format 2-9 (indicating cell DTX or cell DRX operation in the second serving cell) at slot m on the downlink active BWP of the first serving cell. The UE performs a BWP handover after slot m on the downlink active BWP before the handover and before slot m+d. The UE uses slot m on the downlink active BWP before the handover as the start time and performs the operation indicated by DCI format 2-9 on the active BWP of the second serving cell no earlier than slot m+d. Here, the value of d is 3ms, or determined based on the SCS of the BWP before the handover as the reference SCS, or determined based on the SCS of the BWP after the handover as the reference SCS. Figure 7 As shown, the UE performs the cellDTX / DRX operation indicated by DCI format 2-9 in the second serving cell no earlier than time t2 (i.e., the time of slot m+d of the BWP before the BWP handover on the first serving cell). The advantage of this is that it avoids the UE choosing time t1 (t1 is much earlier than t2, even earlier than the time slot m when receiving DCI format 2-9), which would leave the UE with no time to perform the operation indicated by DCI format 2-9 in the second serving cell. Figure 8 As shown, the UE performs the cell DTX / DRX operation indicated by DCI format 2-9 in the second serving cell no earlier than time t2 (i.e., the slot m+d time of the BWP before the BWP handover on the first serving cell). The advantage of this is that it avoids the UE choosing time t1 (which is much later than t2), causing the UE to experience an excessively long delay in the second serving cell and thus fail to execute the operation indicated by DCI format 2-9 in a timely manner, resulting in insignificant network energy savings.

[0107] In some embodiments, the BWP switching includes BWP switching indicated / triggered by DCI carried by PDCCH, or switching triggered by BWP inactivity timer, or BWP switching caused by PRACH procedure, or BWP switching caused by RRC configuration / reconfiguration, or switching caused by SCell activation.

[0108] In some embodiments, if the UE determines slot m according to the method described above, and the UE performs a BWP handover in slot n, then the UE performs the operation according to the cell DTX or cell DRX operation indicated by DCI format 2-9 on the active downlink or uplink BWP of the second serving cell no earlier than slot x. Here, x is max(m+d,n+δ).

[0109] In some embodiments, for BWP handover triggered by RRC configuration / reconfiguration, the UE ignores the DCI format 2-9 indication and determines whether to activate / deactivate cell DTX or cell DRX based on the cell DTX or cell DRX configuration of the RRC configuration / reconfiguration.

[0110] Example 2: Mapping method between cell DTX / DRX operation instruction field and serving cell

[0111] The UE is configured with one or more cells, one or more of which support cell DTX / DRX operations (denoted as network-efficient cells). When the UE is configured to support listening to DCI format 2-9 to perform cell DTX / DRX operations, the starting position of the indication field in DCI format 2-9 corresponding to the network-efficient cell of the UE is indicated by higher-layer signaling.

[0112] In some embodiments, a network energy-saving cell refers to a cell that supports cell DTX / DRX operation, a cell configured with a cell DTX pattern, or a cell designated with a cell DRX pattern.

[0113] In some embodiments, higher-layer signaling instructs a serving cell's cell DTRX (DTX and / or DRX) operation combination to include at least one of the following parameters:

[0114] cell DTRX operation combined index / identifier; or

[0115] Serving cell index / identifier; or

[0116] Cell DTX configuration indicates whether there is a cell DTX operation instruction field; or

[0117] Cell DRX configuration indicates whether there is a cell DRX operation instruction field; or

[0118] Location information, indicating the starting position of the cell DTX / DRX operation indication field in the DCI for this serving cell; or

[0119] Subcarrier spacing indicates the SCS on the serving cell where the BWP is active.

[0120] In some embodiments, the position information is represented by positionInDCI-cellDTRX.

[0121] In some embodiments, higher-level signaling indicates that a list of cellDTRX location information includes at least one of the following parameters:

[0122] List index / identifier; or

[0123] Serving cell index / identifier, indicating the index / identifier of this serving cell; or

[0124] Location information indicates the starting position of the cell DTX / DRX operation indication field in the DCI for this serving cell.

[0125] In some embodiments, the maximum value of the list index / identifier is not greater than the number of network energy-saving cells configured for the UE or the number of cells configured for the UE.

[0126] In some embodiments, the location information corresponds one-to-one with the serving cell index / identifier, or the location information corresponds one-to-one with the serving cell index / identifier from the most significant bit to the least significant bit.

[0127] In some embodiments, higher-level signaling indicates that a list of cellDTRX location information includes at least one of the following parameters:

[0128] Serving cell index / identifier, indicating the index / identifier of one or more cells; or

[0129] Location information indicates the starting position of the instruction information for cell DTX / DRX operations corresponding to one or more cells in the DCI.

[0130] In some embodiments, the serving cell index / identifier is arranged in descending order and corresponds one-to-one with the cell index / identifier configured for the UE in the form of a bitmap from the most significant bit to the least significant bit. In some embodiments, if a bit in the bitmap corresponding to the cell index / identifier is set to 1, it indicates that the cell has a corresponding indication field / indication information in DCI format 2-9.

[0131] In some embodiments, if a bit in the cell index / identifier bitmap is set to 0, it indicates that the cell does not have a corresponding indication field / indication information in DCI format 2-9. In some embodiments, for a serving cell that does not have an indication field / indication information in DCI format 2-9, the location information will not indicate the starting position of the indication information in the corresponding DCI for that cell.

[0132] In some embodiments, higher-layer signaling indicating cellDTRX location information includes at least one of the following parameters:

[0133] Location information indicates the starting position of the indication information in the DCI corresponding to one or more cells.

[0134] In some embodiments, the location information is configured with the starting position of the corresponding indication information in the DCI according to the cell index / identifier of the network energy-saving cell configured to the UE in descending or ascending order. In some embodiments, the number of configurable locations for the location information is no greater than the number of network energy-saving cells configured for the UE.

[0135] In some embodiments, higher-layer signaling indicating cellDTRX location information includes at least one of the following parameters:

[0136] Location information indicates the starting position of the indication information in the DCI corresponding to a specific cell.

[0137] In some embodiments, a specific cell refers to the cell with the smallest cell index / identifier among the network energy-saving cells configured for the UE.

[0138] In some embodiments, if a cell is not configured with a cell DTX pattern but is configured with a joint cell DTX and cell DRX configuration indication, then the cell does not have a corresponding starting position for the indication information in the DCI. In some embodiments, if a cell is not configured with both a cell DTX pattern and a cell DRX pattern, then the cell does not have a corresponding starting position for the indication information in the DCI.

[0139] For example, the UE is configured to listen for DCI format 2-9 on the active downlink BWP of the first serving cell, such as... Figure 9 As shown, the UE determines the starting position of the cell DTX / DRX indication information of one or more network-energy-saving cells in DCI format 2-9 based on the cell index / identifier and location information combination configured by higher-layer parameters. The advantage is that the base station can flexibly configure the cell indication information position and can configure the location information of cells with the same indication information to be identical, thereby reducing Layer 1 signaling overhead. For example... Figure 10 As shown, based on the location information list configured by higher-layer parameters, the UE can determine the starting position information of cell DTX / DRX indication information in the DCI corresponding to each indexed cell. The advantage is that it clearly indicates whether each cell of the UE has cell DTX / DRX indication information and the starting position of the indication information in the DCI. For example... Figure 11 As shown, the UE determines the starting position of the cell DTX / DRX indication information of all network-energy-saving cells in the DCI based on the location information of the specific cell configured by the higher-layer parameters. The advantage is a significant reduction in the overhead of RRC signaling and Layer 1 signaling.

In some embodiments, if the UE CDRX activation period of a third UE on a third serving cell overlaps with the inactive period of cell DTX / DRX, then the fourth UE performs the corresponding UE behavior according to the UE CDRX activation period during the overlapping period on the fourth serving cell.

[0146] In some embodiments, if one or more cells in a cell group are configured with cell DTX / DRX operation, and the UE CDRX activation period and cell DTX / DRX inactivity period overlap in the one or more cells, the UE on a cell in the cell group other than the one or more cells will perform UE behavior according to the UE CDRX activation period during the overlapping period.
