Description

Method and device for determining state of PUR (physical uplink shared channel) resource, storage medium, UE (user equipment) and network side
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for determining a state of a PUR resource, a storage medium, a UE, and a network.
Background
In a current New Radio (NR) system, when a UE in an idle state (idle)/inactive state (inactive) wants to send uplink/downlink data, the UE needs to enter a connected state through a random access process to send the uplink/downlink data. The data transmission mechanism under idle/inactive causes Radio Resource Control (RRC) signaling overhead and User Equipment (UE) energy consumption, and also causes data transmission delay. In order to reduce RRC signaling overhead and UE energy consumption caused by UE sending uplink data under idle, an Early Data Transmission (EDT) mechanism is introduced in a narrowband Band Internet of Things (NB-IOT) system/enhanced machine communication (LTE enhanced MTO, eMTC). However, due to the limited number of bits that can be carried, only a few small upstream packets can be uploaded in this manner.
In order to enable the UE to transmit a larger data packet in an idle state, a conventional NB-IOT/eMTC mechanism is that a network configures dedicated, periodically Preconfigured Uplink Resource (PUR) and corresponding downlink Search space Window (PUR SS Window) for the UE, and the UE may send Uplink data through the Uplink preconfigured Resource and then receive Acknowledgement (ACK)/backoff (fallback) indication or retransmit scheduling information through the corresponding downlink Search space Window (PUR SS Window).
However, in the 5G NR satellite communication standard being established, since the height of the satellite is high (e.g., geostationary satellite: 35786 Km), the channel propagation delay is large. In Non Terrestrial communication (NTN) systems, the HARQ-ACK transmission mechanism may be discarded, i.e. no feedback mechanism is required for the transmission of data.
Specifically, when the PUR transmission mechanism is applied to an NTN scenario, the UE does not need to receive a Hybrid Automatic Repeat reQuest acknowledgement (HARQ-ACK) sent from the base station when performing uplink data transmission by using the PUR. Therefore, no downlink search space window (PUR SS window) exists in the PUR transmission process in the NTN. Under the scenario without the PUR SS window, the network cannot control the effectiveness of the PUR, and when uplink resources are in short supply, the network cannot instruct the UE to fall back to perform data transmission in the RACH/EDT manner, which results in the reliability of data transmission being affected.
There is a need for a method for determining a status of a PUR resource, which enables a UE to accurately determine whether a current status of the PUR resource is an activated status or a released status, so as to accurately determine a data transmission manner, thereby improving reliability of data transmission.

Detailed Description
In the current NR system, UE in idle/inactive state wants to send uplink/downlink data, and needs to enter a connected state through a random access process to send the uplink/downlink data. The data transmission mechanism under idle/inactive causes RRC signaling overhead and UE energy consumption, and also causes data transmission delay. In order to reduce RRC signaling overhead and UE energy consumption caused by UE sending uplink data under idle, an EDT is introduced in NB-IOT/eMTC. The essence of the transmission mechanism is that the UE uses the third message (Msg 3) to carry uplink data to achieve the purpose of uplink data transmission during the process of initiating random access, thereby preventing the UE from entering a connected state. Aiming at uplink data transmission in an idle state, the method effectively reduces the overhead of RRC signaling and the energy consumption of the UE, and simultaneously reduces the energy consumption of the UE. However, due to the limited number of bits that Msg3 can carry, this method can only upload some small upstream packets.
In order to enable the UE to transmit a larger data packet in an idle state, a conventional NB-IOT/eMTC mechanism is that a network configures a dedicated periodic PUR and a corresponding downlink PUR SS Window for the UE, and the UE may send uplink data through an uplink pre-configured resource and then receive an ACK/fallback indication or retransmit scheduling information through the corresponding downlink PUR SS Window. The fallback indication is used to indicate the UE to fall back to the RACH/EDT mode for data transmission, and the network may control the validity of the PUR resource through the fallback indication, that is, when uplink resources of the network are short, the network may indicate the UE to fall back to the RACH/EDT mode for data transmission. The UE can directly send uplink data on the preconfigured uplink resource, so that the UE is prevented from initiating a random access connection state entering process. The UE can transmit data by using the PUR only when the Timing Advance (TA) is valid (i.e., the uplink synchronization is valid).
Currently, the 5G NR also prepares to introduce an uplink pre-configured resource transfer mechanism in the UE RRC _ inactive state.
In non-terrestrial communication systems (e.g., satellite communication), the channel propagation delay is relatively large due to the high altitude of the satellite (e.g., geostationary satellite: 35786 Km). For example, in a geosynchronous satellite scenario, the Round-Trip propagation Delay (Round Trip Delay) between the UE and the satellite is 270.73ms. Due to the large propagation delay, there is a large time interval (i.e. one RTT of time) between the PUR and its corresponding HARQ-ACK reception. In order to save the energy consumption of the UE, after the UE uses the PUR to send uplink data, the UE enters a sleep state (the sleep time may be one RTT), and then wakes up to receive HARQ-ACK.
At present, considering the propagation delay between UE and satellite is too large, HARQ-ACK transmission mechanism may be abandoned in NTN system, i.e. no feedback mechanism is needed for data transmission. In the future, eMTC/NB-IOT can be accessed to a satellite network for communication, and at present, 3gpp is developing research on Internet of things communication based on the satellite network. Specifically, when the PUR transmission mechanism is applied to the NTN scenario, the UE does not need to receive HARQ-ACK from the base station when performing uplink data transmission by using the PUR. Therefore, a downlink search space window (PUR SS window) does not exist in the PUR transmission process in the NTN. Under the scenario without the PUR SS window, the network cannot control the effectiveness of the PUR, and when uplink resources are in short supply, the network cannot instruct the UE to fall back to perform data transmission in the RACH/EDT manner, which results in the reliability of data transmission being affected.
The inventor of the present invention finds, through research, that, in the prior art, when the PUR transmission mechanism is applied to an NTN scenario, the UE does not need to receive HARQ-ACK sent from the base station when performing uplink data transmission by using the PUR. Under the scenario without the PUR SS window, it is difficult for the UE to determine whether the current state of the PUR resource is an active state (also referred to as an active state) or a released state (also referred to as an inactive state), and it is difficult to determine whether to transmit data using the PUR resource or to fall back to perform data transmission in the RACH/EDT manner, which affects data transmission reliability.
In the embodiment of the invention, a PDCCH is periodically monitored on a paging occasion to obtain PUR resource indication information, or a wake-up signal is periodically monitored to obtain the PUR resource indication information, wherein the PUR resource indication information is used for indicating whether PUR resources of one or more UEs are in an activated state or a released state; when the PUR resource indication information is received, determining whether the current state of the PUR resource of the UE is an activated state or a released state; wherein the PUR resource indication information is configured or changed by the network end in response to the state of the PUR resources of the one or more UEs being switched. By adopting the method, the UE can accurately determine the current state of the PUR resource as the activated state or the released state by setting the periodic monitoring DCI to obtain the PUR resource indication information or periodically monitoring the wake-up signal to obtain the PUR resource indication information and determining the current state of the PUR resource of the UE as the activated state or the released state according to the PUR resource indication information, so that the data transmission mode can be accurately judged, and whether the data transmission is carried out by adopting the PUR resource or returning to the RACH/EDT mode to carry out the data transmission can be determined, thereby improving the reliability of the data transmission.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, fig. 1 is a flowchart of a method for determining a status of a PUR resource in an embodiment of the present invention. The method for determining the state of the PUR resource may be used for a UE, and may further include steps S11 to S12:
step S11; monitoring a PDCCH periodically on a paging occasion to acquire PUR resource indication information, or monitoring a wake-up signal periodically to acquire the PUR resource indication information, wherein the PUR resource indication information is used for indicating whether PUR resources of one or more UEs are in an activated state or a released state;
step S12: when receiving the PUR resource indication information, the UE determines whether the current state of the PUR resource is an activated state or a released state;
wherein the PUR resource indication information is configured or changed by the network end in response to the state of the PUR resources of the one or more UEs being switched.
In the specific implementation of step S11, the UE may periodically monitor a Physical Downlink Control Channel (PDCCH) at the paging occasion, or periodically monitor the wake-up signal.
Taking the NR system as an example, the UE periodically (with a period being a DRX period) monitors DCI scrambled by a specific Radio Network Temporary Identity (RNTI) on a Paging Occasion (PO), for example, DCI format1_0 scrambled by a P-RNTI.
Wherein, the Paging message has the functions of: (1) Transmitting a call request to the UE in an RRC IDLE state (RRC _ IDLE); (2) Informing the UE in an RRC _ IDLE/RRC INACTIVE state (RRC _ INACTIVE) and an RRC CONNECTED state (RRC _ CONNECTED) that the system information is changed; (3) An Earthquake and Tsunami notification, which indicates that the UE starts to receive an Earthquake and Tsunami Warning System (ETWS) main notification and/or an ETWS auxiliary notification; the UE is instructed to start receiving Commercial Mobile Alert System (CMAS) notifications. If the terminal is paged or the system information is updated or an earthquake and tsunami occurs, the base station firstly sends a wake-up signal, and the terminal monitors a PDCCH of the paging and receives a paging message after detecting the wake-up signal, otherwise, the terminal keeps a sleep state all the time to achieve the purpose of saving electricity. In NR, the UE may use a Discontinuous Reception mechanism (DRX) in RRC _ IDLE and RRC _ INACTIVE states in order to reduce power consumption.
When Short Message Indicator (2 bits) in the DCI format1 _0scrambled by the P-RNTI is 01, the DCI carries scheduling information, when the Short Message Indicator (2 bits) is 10, the DCI only carries the Short Message (Short Message), and when the Short Message Indicator (2 bits) is 11, the DCI simultaneously carries the scheduling information and the Short Message (Short Message). When the DCI only carries a short Message (short Message), 20bits for scheduling paging are useless, and when the DCI only carries scheduling paging information, 8bits corresponding to the short Message (short Message) are useless. Furthermore, there are 6bits reserved for DCI format1 _0scrambled by P-RNTI.
In the NB-IOT system, the UE periodically (with a DRX period) monitors the scrambled DCI, such as the DCI format N2 scrambled by the P-RNTI, at the Paging Occasion (PO).
The DCI format N2 scrambled by the P-RNTI has 1bit (flag) for distinguishing the paging scheduling information from the Direct Indication information (Direct Indication information), that is, when the flag =0, the DCI is used for carrying the Direct Indication information (8 bits), and when the flag =1, the DCI is used for carrying the paging scheduling information (14 bits). When the DCI is used for carrying direct indication information (8 bits), 6bits exist in the DCI and are not utilized.
In the eMTC system, the UE periodically (with a DRX period) monitors the scrambled DCI, for example, the DCI format 6-2 scrambled by the P-RNTI, at the Paging Occasion (PO).
1bit (flag) in the DCI format N2 scrambled by the P-RNTI is used for distinguishing the paging scheduling information from Direct Indication information (Direct Indication information), that is, when flag =0, the DCI is used for carrying the Direct Indication information, and when flag =1, the DCI is used for carrying the paging scheduling information.
Referring to fig. 2, fig. 2 is a schematic time domain resource diagram of a paging occasion according to an embodiment of the present invention.
As shown in fig. 2, a DRX Cycle (DRX Cycle) is spaced between the POs and the PO, so that the UE can periodically monitor the PDCCH on the PO.
Referring to fig. 3, fig. 3 is a schematic diagram of time domain resources of a wake-up signal according to an embodiment of the present invention.
The Wake Up Signal (WUS) is based on the PDCCH, which is DCI Format 2_6 in nature. The WUS is positioned in front of the PO, and the UE can determine the monitoring time of the WUS through the position of the PO.
With continued reference to fig. 1, in the implementation of step S11, in the NTN system, since the HARQ-ACK transmission mechanism is discarded, i.e. no feedback mechanism is needed for the transmission of data. When the PUR transmission mechanism is applied to the NTN scenario, the UE does not need to receive HARQ-ACK from the base station when performing uplink data transmission by using the PUR, and therefore, a PUR SS window does not exist in the PUR transmission process in the NTN. In the scenario without PUR SS window, the network cannot control the effectiveness of PUR, that is, when the uplink resources are insufficient, the network cannot instruct the UE to fall back to perform data transmission in the RACH/EDT manner.
In the specific implementation of step S12, each time the PUR resource indication information is received, it is determined whether the current state of the PUR resource of the UE itself is an activated state or a released state.
In the embodiment of the invention, the UE can accurately determine the current state of the PUR resource as the activated state or the released state by setting the periodic monitoring DCI to acquire the indication information of the PUR resource or periodically monitoring the wake-up signal to acquire the indication information of the PUR resource and determining the current state of the PUR resource of the UE as the activated state or the released state according to the indication information of the PUR resource, so that the data transmission mode can be accurately judged, and whether the data transmission is carried out by adopting the PUR resource or returning to the RACH/EDT mode is determined, thereby improving the reliability of the data transmission.
In the embodiment of the invention, various modes can be selected according to specific conditions to realize the invention.
In a first specific implementation manner of the embodiment of the present invention, the step of periodically monitoring the PDCCH on the paging occasion to acquire the PUR resource indication information may include: monitoring PDCCH periodically at a paging occasion to acquire one or more DCIs; descrambling the DCI and determining a radio network temporary identifier for scrambling the DCI each time the DCI is received; and determining whether the DCI is used for carrying the PUR resource indication information or not according to the radio network temporary identifier.
In a specific implementation, one or more Radio Network Temporary Identities (RNTIs) may be preset to scramble the DCI, such as the P-RNTI. For example, in the case of 5G NR, the UE will periodically monitor the PDCCH on the PO in idle/inactive state, i.e. monitoring the DCI format1_0 scrambled by P-RNTI.
Further, the DCI includes DCI for scheduling indication or DCI for PUR resource indication, and the DCI for scheduling indication is scrambled by using a preset radio network temporary identifier; the step of determining whether the DCI is used to carry the PUR resource indication information according to the radio network temporary identifier may include: and if the radio network temporary identifier is different from the preset radio network temporary identifier, determining that the PUR resource indication information is carried in the DCI.
In the embodiment of the present invention, the radio network temporary identifier is adopted according to the DCI scrambling and is different from the preset radio network temporary identifier, the DCI is determined to carry the PUR resource indication information, and the UE is notified to acquire the PUR resource indication information in the DCI by setting different radio network temporary identifiers, so that the UE determines the current state of the PUR resource.
In a specific implementation, in order to enable the UE to obtain the PUR release/activation indication by monitoring the PDCCH on the PO, a new RNTI scrambled DCI format1_0 may be introduced, and when the UE detects the new RNTI scrambled DCI format1_0, the UE may consider the DCI for indicating PUR release/activation.
The new RNTI can be PUR-RNTI, so that obvious difference is formed between the new RNTI and the P-RNTI, and the scrambling mode can be determined by the UE.
And when receiving the PUR resource indication information, the UE determines whether the current state of the PUR resource of the UE is an activated state or a released state.
Further, the PUR resource indication information may be carried by using a first preset bit in the DCI, where the first preset bit is used to indicate whether the PUR resource of one or more UEs is in an activated state or a released state. The determining whether the current state of the PUR resource of the UE is the activated state or the released state includes: and determining whether the current PUR resource of the UE is in an activated state or a released state according to the bit value of the first preset bit in the DCI.
Further, the method for determining the state of the PUR resource may be used in a 5G NR system, and the one or more DCIs may be DCI format1_0.
Specifically, when configuring the PUR of the UE, the network may instruct the UE to associate with a specific bit in the DCI format1 \0scrambled by the RNTI, which is equivalent to that the UE configured with the PUR is associated with (corresponds to) a bit in the DCI format1 \0scrambled by the RNTI. When the UE monitors DCI format1 _0scrambled by the RNTI on the PO, the UE can determine whether the PUR resource is released according to the value of the corresponding bit.
In a non-limiting specific embodiment, when the bit value is 1, the UE may consider that the configured PUR is not released (i.e., valid), and when the bit value is 0, the UE may consider that the configured PUR is released (i.e., invalid).
Furthermore, the method for determining the state of the PUR resource is used in an NB-IOT system, and the one or more DCIs are DCI format N2.
Specifically, in NB-IOT, the UE periodically monitors PDCCH on PO in idle state, i.e. monitors DCI format N2 scrambled by P-RNTI. In order to realize that the UE acquires the PUR release/activation indication by monitoring the PDCCH on the PO, the invention introduces a new RNTI (for example, PUR-RNTI) scrambled DCI format N2, and when the UE detects the DCI format N2 scrambled by the RNTI, the UE can consider that the DCI is used for indicating the PUR release/activation. The specific indication process is as follows: when configuring the PUR of the UE, the network may instruct the UE to associate with a specific bit in the DCI format N2 scrambled by the RNTI, which is equivalent to that the UE configured with the PUR is associated with (corresponds to) a bit in the DCI format N2 scrambled by the RNTI. When the UE monitors DCI format N2 scrambled by the RNTI on the PO, the UE may determine whether the PUR resource is released according to the value of the corresponding bit, specifically, when the value of the corresponding bit is 1, the UE may consider that the configured PUR is not released (i.e., valid), and when the value of the corresponding bit is 0, the UE may consider that the configured PUR is released (i.e., invalid).
Further, the method for determining the state of the PUR resource may be used in an eMTC system, and the one or more DCIs may be DCI format6_2.
Specifically, in eMTC, the UE periodically monitors the PDCCH on the PO in idle state, i.e. monitors the P-RNTI scrambled DCI format6_2. In order to enable the UE to acquire the PUR release/activation indication by monitoring the PDCCH on the PO, a new RNTI (e.g., PUR-RNTI) is introduced to scramble the DCI format6_2, and when the UE detects the RNTI scrambled DCI format6_2, the UE may consider the DCI to indicate PUR release/activation. The specific indication process is as follows: when configuring the PUR of the UE, the network may instruct the UE to associate with a specific bit in the DCI format6 _2scrambled by the RNTI, which is equivalent to that the UE configured with the PUR is associated with (corresponds to) a bit in the DCI format6 _2scrambled by the RNTI. When the UE monitors DCI format6_2 scrambled by the RNTI on the PO, the UE can determine whether the PUR resource is released according to the value of the corresponding bit, specifically, when the value of the corresponding bit is 1, the UE may consider that the configured PUR is not released (i.e., valid), and when the value of the corresponding bit is 0, the UE may consider that the configured PUR is released (i.e., invalid).
In the embodiment of the invention, whether the DCI is used for carrying the PUR resource indication information is determined according to the scrambling mode of the DCI, and because the scrambling mode is selected and the signaling overhead is not increased, the reliability of data transmission is improved, and meanwhile, the transmission resources are saved.
In a second specific implementation manner of the embodiment of the present invention, the periodically monitoring the PDCCH at the paging occasion to acquire the PUR resource indication information includes: monitoring a PDCCH periodically at a paging occasion to acquire one or more DCIs; determining whether the DCI is used for carrying a short message or not every time the DCI is received; and if the short message is used for carrying the short message, determining that the DCI carries the PUR resource indication information.
Further, the PUR resource indication information is carried by using a second preset bit in the DCI, where the second preset bit is used to indicate whether the PUR resources of one or more UEs are in an activated state or a released state; the determining whether the current state of the PUR resource of the UE is the active state or the release state includes: and determining whether the current PUR resource of the UE is in an activated state or a released state according to the bit value of the second preset bit in the DCI.
Wherein the second preset bit belongs to at least one part of the remaining bits of the DCI removal short message indication and the bits occupied by the short message.
Taking 5G NR as an example, the information carried by DCI format1 _0representing P-RNTI scrambling is different for different values of Short Messages indicators. When the Short Messages Indicator indicates that the DCI format1 _0scrambled by the P-RNTI carries Short Messages, a lot of residual bits exist in the DCI format1 _0scrambled by the P-RNTI, and at the moment, the release/activation of the PUR can be indicated through the residual bits of the DCI format1 _0scrambled by the P-RNTI, which is specifically as follows:
when configuring the PUR of the UE, the network indicates the UE to be associated with a specific bit in the residual bit of the DCI format1 _0scrambled by the P-RNTI for carrying the short message, which is equivalent to that the UE configured with the PUR corresponds to a specific bit in the residual bit of the DCI format1 _0scrambled by the P-RNTI for carrying the short message. When the UE monitors DCI format1_0 scrambled by P-RNTI carrying a short message on the PO, the UE can determine whether the PUR resource is released according to the value of the corresponding bit, specifically, when the value of the corresponding bit is 1, the UE can consider that the configured PUR is not released (i.e., valid), and when the value of the corresponding bit is 0, the UE can consider that the configured PUR is released (i.e., invalid).
In the embodiment of the invention, whether the DCI carries the PUR resource indication information is determined according to whether the DCI is used for carrying the short message, and because the signaling overhead is not additionally increased when the DCI carries the short message or not, the reliability of data transmission is improved and the transmission resource is saved.
In a third specific implementation manner of the embodiment of the present invention, the step of periodically monitoring the PDCCH at the paging occasion to acquire the PUR resource indication information may include: monitoring PDCCH periodically at a paging occasion to acquire one or more DCIs; determining the value of short message indication information in the DCI each time the DCI is received; and if the value of the short message indication information is a preset value, determining that the DCI is used for carrying the PUR resource indication information.
Further, the PUR resource indication information is carried by a third preset bit in the DCI, where the third preset bit is used to indicate whether the PUR resources of one or more UEs are in an activated state or a released state; the determining whether the current state of the PUR resource of the UE is the active state or the release state includes: and determining whether the current PUR resource of the UE is in an activated state or a released state according to the bit value of the third preset bit in the DCI.
Wherein the third preset bit belongs to at least a part of the bits remaining from the DCI removal short message indication.
Taking 5G NR as an example, different values of Short Messages indicators represent different information carried by DCI format1 _0scrambled by P-RNTI. In order to realize the release/activation of PUR by using bits reserved in DCI format1 _0scrambled by P-RNTI, the invention defines: when the value of the Short Messages Indicator is 00, the DCI format1 _0scrambled by the P-RNTI carries a PUR release/activation indication, and the specific process is as follows:
when configuring the PUR of the UE, the network indicates the UE to be associated with a specific bit in the DCI, which is equivalent to that the UE with the PUR is associated with (corresponding to) one bit in the DCI format1_0 scrambled by the P-RNTI. When the UE monitors DCI format1 _0scrambled by the P-RNTI on the PO and the value of Short Messages Indicator is 00, the DCI carries a PUR release/activation indication, and the UE can determine whether the PUR resource is released according to the value of the corresponding bit. Specifically, when the value of the corresponding bit is 1, the UE may consider that the configured PUR is not released (i.e., valid), and when the value of the corresponding bit is 0, the UE may consider that the configured PUR is released (i.e., invalid).
In the embodiment of the invention, whether the DCI is used for carrying the PUR resource indication information is determined according to the value of the Short Messages Indicator in the DCI, and the bit overhead is not additionally increased, so that the reliability of data transmission is improved, and meanwhile, the transmission resource is saved.
In a fourth specific implementation manner of the embodiment of the present invention, the step of periodically monitoring the PDCCH at the paging occasion to acquire the PUR resource indication information may include: monitoring PDCCH periodically at a paging occasion to acquire one or more DCIs; and acquiring the PUR resource indication information in each DCI.
Further, the PUR resource indication information is carried by using a fourth preset bit in the DCI, where the fourth preset bit is used to indicate whether the PUR resources of one or more UEs are in an activated state or a released state; the step of determining whether the current state of the PUR resource of the UE is the activated state or the released state may include: and determining whether the current PUR resource of the UE is in an activated state or a released state according to the bit value of the fourth preset bit in the DCI.
Still further, the DCI may be DCI format1_0, and the DCI scrambling may employ P-RNTI.
Taking the existing DCI format1_0 scrambled by the UE P-RNTI in NR as an example, since 6bits are not used in the DCI format1_0, the release/activation of PUR can be determined by detecting the DCI format1 _0scrambled by the P-RNTI on PO.
Specifically, when configuring the PUR of the UE, the network may instruct the UE to associate with a specific bit in the reserved bits (which may be 6 bits) of the DCI format1 _0scrambled by the P-RNTI, which is equivalent to that the UE configured with the PUR will correspond to the specific bit (which may be 6 bits) in the reserved bits (6 bits) of the DCI format1 _0scrambled by the P-RNTI. When the UE monitors DCI format1_0 scrambled by the P-RNTI on the PO, the UE can determine whether the PUR resource is released according to the value of the corresponding bit, specifically, when the value of the corresponding bit is 1, the UE can consider that the configured PUR is not released (i.e., valid), and when the value of the corresponding bit is 0, the UE can consider that the configured PUR is released (i.e., invalid).
Wherein the fourth preset bit may belong to a reserved bit of the DCI, and the reserved bit may be an unused bit.
In the embodiment of the present invention, for DCI having unused bits, each piece of DCI may be provided with PUR resource indication information, and then the PUR resource indication information is changed during state switching, which may increase the number of times that the UE receives the PUR resource indication information, thereby further improving the reliability of determining the state of its own current PUR resource.
In a fifth specific implementation manner of the embodiment of the present invention, the step of periodically monitoring the wake-up signal to obtain the PUR resource indication information may include: monitoring a wake-up signal periodically to acquire information carried by the wake-up signal; and acquiring the PUR resource indication information in each wake-up signal.
Further, the PUR resource indication information is carried by using a fifth preset bit in the wake-up signal, where the fifth preset bit is used to indicate whether the PUR resources of one or more UEs are in an activated state or a released state; the determining whether the current state of the PUR resource of the UE is the activated state or the released state includes: and determining whether the current PUR resource of the UE is in an activated state or a released state according to the bit value of the fifth preset bit in the wake-up signal.
The fifth preset bit may belong to the wake-up signal new bit field.
Further, the wake-up signal may be DCI format 2_6.
For example, in the case of 5G NR, the UE periodically listens to the WUS before the PO (i.e., DCI Format 2_6). In order to realize the release/activation of UE PUR indicated by the WUS, the invention is designed to add a bit field in DCI Format 2_6, wherein the bit field contains X bits and is specially used for indicating the release of UE PUR. When configuring the PUR of the UE, the network indicates that the UE is associated with a specific bit (i.e. one bit in X bits) in the DCI Format 2_6, which is equivalent to that the UE configured with the PUR is associated with (corresponds to) a specific bit in the DCI Format 2_6. When the UE monitors DCI Format 2 _6on the PO, the UE can determine whether the PUR resource is released according to the value of the corresponding bit. Specifically, when the value of the corresponding bit is 1, the UE may consider that the configured PUR is not released (i.e., valid), and when the value of the corresponding bit is 0, the UE may consider that the configured PUR is released (i.e., invalid).
In the embodiment of the invention, the PUR resource indication information can be set in each wake-up signal, so that the PUR resource indication information is changed during state switching, the times of receiving the PUR resource indication information by the UE can be increased, and the reliability of determining the current state of the PUR resource by the UE is further improved.

In the embodiment of the present invention, the DCI configured to be carried by the PDCCH carries the PUR resource indication information, and since the short message indication information already exists in the prior art, the use of a certain value in the short message indication information does not increase signaling overhead, which is helpful to improve reliability of data transmission and save transmission resources.
