Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and more specifically, to a method for a user equipment to send a scheduling request to a base station and a corresponding user equipment. Background Art

[0002] Network energy saving is beneficial to reducing environmental impact and saving operator costs. By lengthening the time interval for the base station to continuously receive and send data and shutting down the transmission and reception of some symbols, the base station can be put into a sleep state, or the cell where it is located can be put into a network energy saving mode, thereby reducing the power consumption of the base station and achieving network energy saving. For the above reasons, in December 2022, at the RAN#98e plenary meeting of the 3rd Generation Partnership Project (3GPP), the NR network energy saving work project for version 18 (see non-patent document: RP-223540 New WID: Network energy savings for NR) was approved. One of the goals of this work project is to enhance cell DRX and cell DTX in the RRC connected state, that is, network discontinuous reception and network discontinuous transmission, so as to achieve network energy saving.

[0003] The present invention discusses how the UE triggers and transmits a scheduling request, how to trigger a random access process related to the scheduling request, and how the UE requests activation / deactivation of the cell DRX and / or cell DTX after the introduction of the cell DRX and / or cell DTX. Summary of the invention

[0004] The object of the present invention is to provide a method and user equipment for sending a scheduling request from a user equipment to a base station, which can avoid degradation of service performance of a UE due to discontinuous transmission by a base station.

[0005] According to one aspect of the present invention, a method for sending a scheduling request by a user equipment to a base station is provided, comprising: for a pending scheduling request in a pending SR state, if the value of an SR counter is less than the maximum number of SRs to be sent, instructing the physical layer to send the pending SR on a valid PUCCH resource, the SR counter represents the number of pending SRs sent, and is reset to an initial value when a certain SR is triggered and there are no other SRs in a pending state; and when a service cell corresponding to the valid PUCCH resource is configured with discontinuous transmission, i.e., DTX, and the DTX function is activated and a first condition is met, increasing the value of the SR counter by a corresponding value, the first condition comprising at least one of the following: the valid PUCCH resource for sending the pending SR does not overlap with the inactive time of DTX of the service cell; the transmission timing of the pending SR does not overlap with the inactive time of DTX of the service cell.

[0006] According to another aspect of the present invention, a method for sending a scheduling request by a user equipment to a base station is provided, comprising: for a pending scheduling request in a pending state, i.e., a pending SR, if there is a valid PUCCH resource for sending the pending SR, and in a case where a service cell corresponding to the valid PUCCH resource is configured with discontinuous transmission, i.e., DTX, determining whether a sendable condition is currently met, the sendable condition indicating that the pending SR can be sent to the base station; and sending the pending SR on the valid PUCCH resource if the sendable condition is met.

[0007] According to the present invention, it is possible to avoid degradation of UE service performance due to discontinuous transmission by a base station. BRIEF DESCRIPTION OF THE DRAWINGS

There may be a relationship of inclusion and being included between the two, and they do not necessarily refer to completely different contents.

[0070] Hereinafter, a description is given of related art of the present invention.

[0071] SR

[0072] The SR is used by the UE to request uplink resources, such as UL-SCH resources, for new transmission.

[0073] The MAC entity can be configured with zero, one or more SR configurations. An SR configuration consists of a set of PUCCH resources used for SR, which can span different BWPs and different cells.

[0074] Each SR configuration corresponds to one or more logical channels. Each logical channel can be mapped to zero or one SR configuration, which is configured by RRC. RRC configures the following parameters for the scheduling request process: sr-ProhibitTimer (for each SR configuration), sr-TransMax (for each SR configuration). sr-ProhibitTimer: SR prohibition timer, a timer for transmitting SR on PUCCH, used to control the time interval between two SR transmissions, in ms. sr-TransMax: The maximum number of SR transmissions.

[0075] The UE variable SR_COUNTER in the UE (for each SR configuration) is a counter used for the scheduling request process.

[0076] If an SR is triggered and there is no other SR pending corresponding to the same SR configuration, the MAC entity shall set the SR_COUNTER of the corresponding SR configuration to 0. When an SR is triggered, it shall be considered pending until it is canceled.

[0077] Valid PUCCH resources: Only the PUCCH resources on the BWP that are active at the time of SR transmission are considered valid.

[0078] As long as there is at least one SR pending, the MAC entity performs the following operations on each pending SR:

[0079] -If the MAC entity is not configured with valid PUCCH resources for the pending SR, a random access procedure is initiated on the SpCell and the pending SR is cancelled;

[0080] -Otherwise, for the SR configuration corresponding to the pending SR, if the MAC entity has an SR transmission opportunity (occasion) on the valid PUCCH resources for the SR configuration, and if the sr-ProhibitTimer is not running during SR transmission, and if the PUCCH resources of the SR transmission opportunity do not overlap with the measurement gap, then further determine whether the SR transmission opportunity and UL-SCH resources, SL-SCH resources overlap, as well as priority information. If the conditions are met (for example: if the MAC entity can perform SR transmission and SL-SCH resource transmission at the same time), the SR transmission is considered to be a high-priority SR transmission, otherwise the SR transmission is considered to be a low-priority SR transmission.

[0081] -While considering the SR transmission as a high priority SR transmission, the following operations can also be performed:

[0082] If SR_COUNTER<SR-TransMax

[0083] Instruct the physical layer to send the SR on a valid PUCCH resource for (one) SR;

[0084] If no LBT fault indication is received from the lower layer, SR_COUNTER is incremented by 1 and the sr-ProhibitTimer is started;

[0085] Otherwise (i.e., an LBT failure indication is received from the lower layer), if the LBT failure recovery configuration lbt-FailureRecoveryConfig is not configured, SR_COUNTER is incremented by 1;

[0086] Otherwise (i.e., SR_COUNTER>=SR-TransMax), notify RRC to release the PUCCH of all serving cells, notify RRC to release the SRS of all serving cells, clear any configured downlink allocation and uplink authorization, clear any PUSCH resources for semi-persistent CSI reporting, initiate a random access procedure on SpCell, and cancel all pending SR(s).

[0087] The reasons for triggering SR include but are not limited to: reporting UE buffer data status (BSR: Buffer Status Reporting), beam failure recovery, positioning measurement gap activation / deactivation request, continuous LBT failure recovery, timing advance report, etc. Generally, these reasons require sending MAC CE to the network. After the SR is sent, the UE monitors PDCCH to obtain the uplink authorization for the new transmission. When the uplink authorization is obtained, the MAC CE that triggers the SR is sent. After the MAC CE is sent, the corresponding pending SR is canceled and the corresponding sr-ProhibitTimer timer is stopped.

[0088] Cell DTX

[0089] In order to save power consumption of the network, the network can transmit discontinuously. The network can configure Cell DTX for the UE so that the UE knows how the network transmits discontinuously in a certain cell. After the network configures Cell DTX for the UE, Cell DTX can be activated by default, and Cell DTX can be activated and / or deactivated by indication after configuration. The Cell DTX configuration can include information such as the discontinuous transmission period, the duration of the start of transmission, the offset of the start of transmission, etc. Cell DTX can be divided into two parts: activation time and inactivation time. The network transmits data during the activation time, and does not transmit data during the inactivation time. The activation time of Cell DTX includes a transmission duration (on-duration) at the beginning of the Cell DTX cycle, and may also include a portion of the transmission duration extended due to various reasons (for example, due to the receipt of new uplink data from the UE, the transmission duration is extended in order to send a response to the UE). The inactivation time of Cell DTX can be other times in the Cell DTX cycle excluding the activation time of Cell DTX.

[0090] During the activation time of Cell DTX, the UE needs to monitor PDCCH to obtain downlink allocation and / or uplink authorization for new transmission and receive downlink data, that is, the UE's downlink monitoring and receiving behavior is not affected. During the inactive time of Cell DTX, the UE generally does not need to monitor PDCCH to obtain downlink allocation and / or uplink authorization for new transmission. However, the UE still needs to monitor paging and obtain system messages. Generally, during the inactive time of Cell DTX, the UE's uplink transmission is not affected.

[0091] Cell DRX

[0092] In order to save power consumption of the network, the network can perform discontinuous reception. The network can configure Cell DRX for the UE so that the UE knows how the network performs discontinuous reception in a certain cell. After the network configures Cell DRX for the UE, Cell DRX can be activated by default, and Cell DRX can be activated and / or deactivated by indication after configuration. The Cell DRX configuration can include information such as the discontinuous reception period, the duration for starting reception, and the offset for starting reception. Cell DRX can be divided into two parts: activation time and inactivation time. The network receives data during the activation time, and does not receive data during the inactivation time. The activation time of Cell DRX includes a reception duration (on-duration) at the beginning of the Cell DRX cycle, and may also include a portion of the reception duration extended due to various reasons (for example, due to the sending of new downlink data, the reception duration is extended in order to receive the response of the UE). The inactivation time of Cell DRX can be other times in the Cell DRX cycle excluding the activation time of Cell DRX.

[0093] During the activation time of Cell DRX, UE performs uplink transmission normally. During the inactive time of Cell DRX, UE performs random access process normally, but if SR is triggered, SR pending can be sent until the end of Cell DRX deactivation time (i.e., entering Cell DRX activation time), which means that if the SR transmission timing overlaps with the inactive time of Cell DRX, SR will not be sent. Generally, during the inactive time of Cell DRX, UE downlink monitoring or reception is not affected.

[0094] The UE triggers and sends SR to the network during the inactive time of Cell DTX. Since the network is in discontinuous reception, the UE does not monitor PDCCH to obtain the link authorization for new transmission, and cannot send the MAC CE that triggers the SR. The pending SR will always exist and cannot be cancelled. When the cumulative number of SRs sent exceeds the maximum number of times, an exception will occur, causing the UE to mistakenly clear the PUCCH resources. At the same time, the introduction of Cell DRX and Cell DTX may cause the UE's service performance to deteriorate.

[0095] The present invention discusses how UE triggers and transmits SR, how to trigger SR-related random access procedures, and how UE requests activation / deactivation of cell DRX and / or cell DTX after the introduction of cell DRX and / or cell DTX. Through the present invention, abnormal situations of SR can be avoided, and UE can be prevented from mistakenly clearing PUCCH resources, while reducing the impact of Cell DRX and Cell DTX on the service performance of UE.

[0096] The following first refers to Figure 1 and Figure 2 The outline of the present invention will be described.

[0097] Figure 1 The present invention is a flowchart of a method for sending a scheduling request from a user equipment to a base station according to an embodiment of the present invention.

[0098] like Figure 1 As shown, in step 102, it is determined whether there is a pending SR in a waiting state. When there is a pending SR in a waiting state, for the pending SR, in step 104, it is determined whether the value of the SR counter is less than the maximum number of SR transmissions. If the value of the SR counter is less than the maximum number of SR transmissions, then in step 106, the physical layer is instructed to transmit the pending SR on a valid PUCCH resource.

[0099] Here, the SR counter indicates the number of pending SRs sent, and is reset to an initial value when there are no other pending SRs when a certain SR is triggered.

[0100] Then, in step 108, it is determined whether the following conditions are met: the serving cell corresponding to the valid PUCCH resource is configured with discontinuous transmission (DTX) and the DTX function is activated and the first condition is met. The first condition includes at least one of the following: the valid PUCCH resource used to send the pending SR does not overlap with the inactive time of the DTX of the serving cell; the transmission timing of the pending SR does not overlap with the inactive time of the DTX of the serving cell.

[0101] If the determination result of step 108 is “yes”, then in step 110 , the value of the SR counter is increased by a corresponding value.

[0102] When the determination result in steps S104 and S108 is "No", the corresponding pending SR may be kept in the pending state and executed again. Figure 1 You can also cancel the pending SR.

[0103] according to Figure 1 In the embodiment shown, the SR counter is incremented by a corresponding value when the first condition is met, instead of incrementing the counter by a corresponding value each time the physical layer is instructed to send a pending SR, and the pending SR that cannot be responded to by the base station due to overlap with DTX is not counted. As a result, the value of the SR counter reflects the number of pending SRs that are actually sent and can get a response from the base station. Therefore, this embodiment can avoid abnormalities caused by the value of the SR counter not reflecting the actual number of pending SRs that can get a response, and can avoid, for example, inappropriate cancellation of pending SRs or erroneous clearing of PUCCH resources.

[0104] Figure 2 is a flowchart of a method for sending a scheduling request by a user equipment to a base station according to another embodiment of the present invention.

[0105] like Figure 2 As shown, in step 202, it is determined whether there is a pending SR in a waiting state. When there is a pending SR in a waiting state, for the pending SR, in step 204, it is determined whether there is a valid PUCCH resource for sending the pending SR.

[0106] If there are valid PUCCH resources for sending the pending SR, then in step S206, it is determined that the serving cell corresponding to the valid PUCCH resources is configured with DTX.

[0107] In the case where the serving cell corresponding to the valid PUCCH resource is configured with discontinuous transmission, i.e., DTX, in step 208, it is determined whether a condition for transmission is currently satisfied, wherein the condition for transmission indicates that the pending SR can be transmitted to the base station. The condition for transmission can be set corresponding to the DTX activation time and the DTX inactivation time when the DTX function is activated. A DTX cycle includes the DTX activation time when the base station transmits data and the DTX inactivation time when the base station does not transmit data.

[0108] When the transmittable condition is met, at step 210, the pending SR is transmitted on the valid PUCCH resource.

[0109] In one example, the transmittable condition includes a first transmittable condition when the DTX function is activated and within the DTX activation time, and a second transmittable condition when the DTX function is activated and within the DTX non-activation time. At this time, the pending SR can be sent on the valid PUCCH resource when either the first transmittable condition or the second transmittable condition is met. Specific examples of the first transmittable condition and the second transmittable condition will be specifically described in the embodiments described later.

[0110] When the determination results in steps 204 and 208 are "No", the pending state of the corresponding pending SR may be maintained and the process may be re-executed. Figure 2 The process shown may also cancel the pending SR and initiate a random access process. For example, when the determination results in steps 204 and 208 are "no" and the pending SR is determined to be a high-priority SR, a random access process may be initiated.

[0111] It should be noted that in Figure 1 and Figure 2The order of the determination steps shown in the figure is only an example. In other embodiments, the execution order of the determination steps can be reversed or performed in parallel. Figure 2 The order of S204 and S206 can be swapped or performed in parallel.

[0112] Hereinafter, several embodiments of the present invention for solving the above problems are described in detail.

[0113] Unless otherwise specified, in the following embodiments, when the UE triggers the need to report the UE buffer data status (BSR: Buffer Status Reporting), or triggers beam failure recovery, or triggers a positioning measurement gap activation / deactivation request, or triggers continuous LBT failure recovery, or triggers a timing advance report, the UE can trigger an SR. At the same time, the UE may also trigger an SR due to the need to send other MAC CEs.

[0114] Unless otherwise specified, in the following embodiments, the method for determining whether an SR is a high-priority SR transmission includes but is not limited to: if the PUCCH resources corresponding to the SR transmission timing do not overlap with the UL-SCH resources; if the MAC entity can simultaneously perform SR transmission and SL-SCH resource transmission, etc.

[0115] Unless otherwise specified, in the following embodiments, sr-ProhibitTimer (for each SR configuration) and sr-TransMax (for each SR configuration) are parameters configured by the network. sr-ProhibitTimer: SR prohibition timer, a timer for transmitting SR on PUCCH, used to control the time interval between two SR transmissions, in ms. sr-TransMax: The maximum number of SR transmissions. The UE variable SR COUNTER (for each SR configuration) in the UE is a counter used for scheduling request procedures.

[0116] Optionally, as in the following embodiments, the Cell DTX configuration may be for each serving cell.

[0117] Example 1

[0118] Figure 3 It is a flowchart of a method for sending a scheduling request from a user equipment to a base station according to embodiment 1 of the present invention.

[0119] Alternatively, if Figure 3 As shown, this embodiment includes steps 301, 303 and 305.

[0120] Optionally, in step 301, the UE receives Cell DTX configuration information sent by the network. Optionally, the Cell DTX configuration information may be included in a system message, an RRC-specific message (e.g., an RRC reconfiguration message), a MAC CE, or a physical layer indication (e.g., a DCI). Optionally, when the UE receives Cell DTX configuration information (of all serving cells or a certain / certain serving cells), it is considered that (the serving cell) is configured with Cell DTX, and optionally, it may be considered that the Cell DTX function (of the serving cell) is activated.

[0121] Optionally, in step 303, the UE monitors and receives Cell DTX activation / deactivation indication information, and the indication information may be included in a MAC CE or a physical layer indication (e.g., DCI). Optionally, the Cell DTX activation / deactivation indication information may activate / deactivate the Cell DTX of all service cells, or may activate / deactivate the Cell DTX of one or some service cells. If the indication information received by the UE indicates activation / deactivation of the Cell DTX of all service cells, the UE considers that the Cell DTX of all service cells is activated / deactivated. If the indication information received by the UE indicates activation / deactivation of the Cell DTX of one or some service cells, the UE considers that the Cell DTX of the service cell is activated / deactivated. Optionally, the indication information indicates a method for activating Cell DTX, for example, the MAC CE or physical layer indication includes an indication for activating Cell DTX of all service cells or certain service cells / certain service cells, and / or the indication for activating Cell DTX of all service cells or certain service cells / certain service cells is set to a specific value, for example, 1; the indication information indicates a method for deactivating Cell DTX, for example, the MAC CE or physical layer indication includes an indication for deactivating Cell DTX of all service cells or certain service cells / certain service cells, and / or the indication for activating Cell DTX of all service cells or certain service cells / certain service cells is set to another specific value, for example, 0.

[0122] Optionally, in step 305, when SR is triggered, as long as there is at least one SR pending, the MAC entity performs a judgment on each pending SR.

[0123] If SR_COUNTER < SR-TransMax, the physical layer is instructed to send the SR on the valid PUCCH resource of (one) SR. If at least one of the following first conditions is met, the SR_COUNTER is incremented by 1:

[0124] - Cell DTX (of the corresponding serving cell) is configured;

[0125] -The Cell DTX function (of the corresponding serving cell) is activated;

[0126] - The effective PUCCH resources (of the SR) and the inactive time of Cell DTX (of the corresponding serving cell) do not overlap;

[0127] -The SR transmission timing does not overlap with the Cell DTX inactive time (of the corresponding serving cell);

[0128] - There is at least one valid PUCCH resource for pending SR transmission and the inactive time of CellDTX (of the corresponding serving cell) does not overlap.

[0129] The “effective PUCCH resources of the SR” may also be expressed as “effective PUCCH resources of the SR transmission (or the SR transmission timing)”. Optionally, the “corresponding serving cell” may refer to the serving cell corresponding to the effective PUCCH resources, or to the serving cell corresponding to the SR transmission timing.

[0130] Optionally, it is also possible to first determine if no LBT fault indication is received from the lower layer, or if an LBT fault indication is received from the lower layer but the LBT failure recovery configuration lbt-FailureRecoveryConfig is not configured, and then determine the first condition as above.

[0131] Optionally, it can be determined first if the MAC entity has valid PUCCH resources configured for the pending SR, and for the SR configuration corresponding to the pending SR, if the MAC entity has an SR transmission occasion (occasion) on the valid PUCCH resources for the SR configuration, and if sr-ProhibitTimer is not running during SR transmission, and if the PUCCH resources of the SR transmission occasion do not overlap with the measurement gap, and it can be determined whether the SR is a high-priority SR transmission. After determining that the SR transmission is a high-priority SR transmission, it is then determined whether SR_COUNTER<SR-TransMax.

[0132] Example 2

[0133] Figure 4 It is a flowchart of a method for sending a scheduling request from a user equipment to a base station according to embodiment 2 of the present invention.

[0134] According to embodiment 1, optionally, Figure 4 As shown, this embodiment includes steps 401, 403 and 405.

[0135] Optionally, the difference between step 401 and step 301 is that the UE also receives the configuration of the second maximum SR transmission number sent by the network, and the configuration of the second maximum SR transmission number may be included in the system message, RRC-specific message (such as RRC reconfiguration message), MAC CE, and physical layer indication (such as DCI). Among them, the second maximum SR transmission number refers to the maximum SR transmission number of the UE when the CellDTX function is activated, or the Cell DTX function is activated and is in the non-activated time of Cell DTX. Optionally, the value of the second maximum SR transmission number may be greater than the value of SR-TransMax. Optionally, at this time, SR-TransMax may refer to the maximum SR transmission number of the UE when the Cell DTX function is not activated, or the Cell DTX function is activated and is in the Cell DTX activation time, which can be regarded as the first maximum SR transmission number. Optionally, the second maximum SR transmission number will only appear when the Cell DTX configuration appears, that is, the second maximum SR transmission number will be configured only when Cell DTX is configured. The other operations of step 401 are the same as step 301.

[0136] Optionally, step 403 is the same as step 303 .

[0137] Optionally, in step 405, when SR is triggered, as long as there is at least one SR pending, the MAC entity performs a judgment on each pending SR.

[0138] Optionally, if at least one of the following second conditions is met, and if SR_COUNTER is less than the second SR maximum transmission number, then the physical layer is instructed to send SR on the valid PUCCH resources of (one) SR; otherwise (or if at least one of the first conditions is met), and if SR_COUNTER is less than the first SR maximum transmission number (SR-TransMax), then the physical layer is instructed to send SR on the valid PUCCH resources of (one) SR.

[0139] The second condition includes at least one of the following:

[0150] According to embodiment 1, optionally, Figure 5 As shown, this embodiment includes steps 501, 503 and 505.

[0151] Optionally, the difference between step 501 and step 301 is that the UE also receives the configuration of the second SR prohibit timer sent by the network, and the second SR prohibit timer configuration may be included in a system message, an RRC-specific message (e.g., an RRC reconfiguration message), a MAC CE, or a physical layer indication (e.g., a DCI). Among them, the second SR prohibit timer refers to the time interval between two SRs sent by the UE when the Cell DTX function is activated, or when the Cell DTX function is activated and is within the inactive time of the Cell DTX. Optionally, at this time, sr-ProhibitTimer may refer to the SR prohibit timer of the UE when the Cell DTX function is not activated, or when the Cell DTX function is activated and is within the active time of the Cell DTX, and may be regarded as the first SR prohibit timer. Optionally, the second SR prohibit timer will only appear when the Cell DTX configuration appears, that is, the second SR prohibit timer will be configured only when the Cell DTX is configured. The other operations of step 501 are the same as step 301.

[0152] Optionally, step 503 is the same as step 303 .

[0153] Optionally, in step 505, when SR is triggered, as long as there is at least one SR pending, the MAC entity performs a judgment on each pending SR.

[0154] Optionally, for the SR configuration corresponding to the pending SR, if at least one of the second conditions is met, it is further determined whether the second SR prohibit timer is not running during SR transmission, and if the second SR prohibit timer is not running during SR transmission, it is further determined whether the SR is a high-priority SR transmission. For the SR configuration corresponding to the pending SR, if at least one of the first conditions is met (or at least one of the second conditions is not met), it is further determined whether the first SR prohibit timer (sr-ProhibitTimer) is not running during SR transmission, and if the first SR prohibit timer (sr-ProhibitTimer) is not running during SR transmission, it is further determined whether the SR is a high-priority SR transmission.

[0155] Optionally, if SR_COUNTER<SR-TransMax (maximum number of first SR transmissions) (or SR_COUNTER<maximum number of second SR transmissions), instruct the physical layer to send SR on the valid PUCCH resource of (one) SR. If no LBT failure indication is received from the lower layer, then: if at least one of the second conditions is met, start the second SR prohibit timer; otherwise (or if at least one of the first conditions is met), start the first SR prohibit timer (sr-ProhibitTimer).

[0156] Optionally, if SR_COUNTER>=SR-TransMax (maximum number of first SR transmissions) (or SR_COUNTER>=maximum number of second SR transmissions), if at least one of the first conditions is met, the UE performs at least one of the following first actions; otherwise (or if at least one of the second conditions is met), the UE initiates a random access procedure on the SpCell (or on the serving cell) and / or cancels all pending SR(s).

[0157] The first action includes at least one of the following:

[0158] -Notify RRC to release PUCCH of all serving cells;

[0159] -Notify RRC to cancel SRS of all serving cells;

[0160] - Clear any configured downlink allocations and uplink grants;

[0161] - Clear any PUSCH resources for semi-persistent CSI reporting;

[0162] -Initiate a random access procedure on the SpCell (or on the serving cell);

[0163] -Cancel all pending SR(s).

[0164] Optionally, it may be possible to first determine if the MAC entity has valid PUCCH resources configured for the pending SR, and for the SR configuration corresponding to the pending SR, if the MAC entity has an SR transmission opportunity (occasion) on the valid PUCCH resources configured for the SR, then determine whether the first condition is met and / or determine whether the second condition is met.

[0165] Example 4

[0168] Optionally, step 601 is the same as step 301 , and step 603 is the same as step 303 .

[0169] Optionally, in step 605, when selecting valid PUCCH resources for SR, only PUCCH resources on the BWP that are in an activated state during SR transmission and that can satisfy at least one of the first conditions are considered valid PUCCH resources.

[0170] Optionally, as long as there is at least one SR pending, the MAC entity performs a judgment on each pending SR. If the MAC entity has no valid PUCCH resources for the pending SR, and if the pending SR is a high priority SR under CellDTX, a random access procedure is initiated on the SpCell (or on the serving cell), and / or the pending SR is canceled.

[0171] Among them, whether the SR is a high priority SR under Cell DTX can be obtained by receiving SR configuration information sent by the network, that is, the SR configuration information sent by the network includes an indication of whether a certain SR configuration is a high priority SR under Cell DTX.

Optionally, the CellDRX activation / deactivation indication information can activate / deactivate the Cell DRX of all service cells, and can also activate / deactivate the Cell DRX of one or some service cells. If the indication information received by the UE indicates activation / deactivation of the Cell DRX of all service cells, the UE considers that the Cell DRX of all service cells is activated / deactivated. If the indication information received by the UE indicates activation / deactivation of the Cell DRX of one or some service cells, the UE considers that the Cell DRX of the service cell is activated / deactivated. Optionally, the indication information indicates a method for activating Cell DRX, such as a MAC CE or a physical layer indication including an indication for activating Cell DRX of all service cells or a certain / certain service cells, and / or the indication for activating Cell DRX of all service cells or a certain / certain service cells is set to a specific value, such as 1; the indication information indicates a method for deactivating Cell DRX, such as a MAC CE or a physical layer indication including an indication for deactivating Cell DRX of all service cells or a certain / certain service cells, and / or the indication for activating Cell DRX of all service cells or a certain / certain service cells is set to another specific value, such as 0.
