detailed description

As mentioned in the background art, in the prior art, when PUR is used for data transmission and reception, UE energy consumption is relatively large.

In NR, the UE can use Discontinuous Reception (DRX) in the RRC idle state and the RRC inactive state (DRX) to reduce power consumption. The UE listens to a paging occasion (Paging occasion, PO for short) in each DRX cycle. Since NR introduces the operation of beam management, the length of a single PO is one beam scanning period, and the same paging message is repeatedly sent in all beams in the scanning mode. The selection of the beam used to receive the paging message depends on the UE implementation. A paging frame is a radio frame and can contain one or more POs, and even a paging frame is the starting point of a PO. The determination of the paging frame is similar to the calculation method in Long Term Evolution (LTE).

In the current NR system, the UE in the idle or inactive state (ie idle/inactive state) wants to send uplink/downlink data, and it needs to enter the connected state through the random access process before sending uplink/downlink data. , "/" means or. This data transmission mechanism in an idle or inactive state will increase RRC signaling overhead and UE energy consumption, and at the same time increase the delay of data transmission.

In order to reduce the RRC signaling overhead and UE energy consumption caused by the UE sending uplink data in the idle state, in the Narrow Band Internet of Things (NB-IOT) system, an early data transmission mechanism (Early Data Transmission, EDT for short). The essence of the EDT transmission mechanism is that when the UE initiates a random access process, a third message (Message3, Msg3 for short) is used to carry uplink data to achieve the purpose of uplink data transmission, thereby preventing the UE from entering the connected state. For the uplink data transmission in the idle state, this method effectively reduces the RRC signaling overhead and UE energy consumption, and at the same time reduces the UE transmission delay. However, due to the limited number of bits that Msg3 can carry, this method can only upload some small uplink data packets.

In order to further reduce the RRC signaling overhead caused by the UE sending uplink data in idle state and increase the rate of uplink data transmission, NB-IOT introduces periodic uplink pre-configured resources (Preconfigure Uplink resource, referred to as PUR). The UE is in the PUR The uplink data can be sent directly, which greatly reduces the RRC signaling overhead and transmission delay caused by the uplink transmission.

The UE can send uplink data through PUR, and receive retransmission scheduling information or confirmation information in the corresponding uplink search space window (PUR search space window), such as ACKnowledgement/Non-ACKnowledgement (ACK/NACK) ).

In order to enable the UE to directly receive downlink data in an idle or inactive state, the network can issue downlink scheduling information through the downlink search space window corresponding to the PUR, and the UE can receive downlink data by monitoring the PDCCH in the downlink search space window. In this downlink data transmission mode, the UE needs to periodically monitor the PDCCH scheduling downlink data, which will cause energy consumption for the UE.

In order to solve the above technical problem, an embodiment of the present invention provides a signaling sending method, including: sending indication information, the indication information is used to indicate whether a terminal monitors the PDCCH in a pre-configured uplink resource search space window. In the embodiment of the present invention, by sending indication information, the UE in the idle state or in the inactive state can know whether the network (for example, the base station) transmits PDCCH signaling in the PUR search space window, and the UE only needs to know that the network issues It is sufficient to monitor the PDCCH during PDCCH signaling, which can prevent the UE from periodically monitoring the PDCCH for scheduling downlink data, and can save the energy consumption of the UE.

In order to make the above objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic flowchart of a signaling sending method according to an embodiment of the present invention. The signaling sending method can be applied to the network side, for example, executed by a base station.

Specifically, the signaling sending method may only include step S102, or may include step S101 and step S102:

Step S101, before issuing the instruction information, receive uplink data, and the uplink data is transmitted by PUR.

Step S102: Issue instruction information, where the instruction information is used to indicate whether the terminal monitors the PDCCH in the PUR search space window.

More specifically, if the UE does not send uplink data in the PUR, the base station may issue the indication information in step S102. The indication information is used to indicate whether the terminal monitors the PDCCH in the PUR search space window.

In a non-limiting example, the indication information may be carried and issued by a wake-up signal (Wake Up Signal, WUS for short). In a specific implementation, the wake-up signal may be located between the PUR and the PUR search space window, and the PUR search space window is associated with the PUR and is located after the PUR. The PUR has a one-to-one correspondence with the PUR search space window.

If the UE sends uplink data in the PUR, the base station can perform step S101, that is, receive the uplink data in the PUR. After that, the indication information may be issued in step S102 to notify the UE whether to monitor the PDCCH in the PUR search space window.

In a non-limiting example, the uplink data may include downlink beam information, and the downlink beam information may include a downlink beam expected to be used by the terminal. In a specific implementation, the downlink beam information may be implicitly indicated through dedicated resources, or may be explicitly indicated. For example, the UE may use the uplink resource corresponding to the expected downlink beam to transmit the uplink data. After the base station receives the uplink data on the uplink resource, it can know the downlink beam expected to be used by the terminal. . For another example, the UE may use bits to expressly indicate the downlink beam that the network is expected to use.

In a non-limiting example, the indication information is carried and issued in an ACK downlink control information (Downlink Control Information, DCI for short)/NACK associated with the uplink data. The ACK DCI/NACK is issued using the resources in the PUR search space window associated with the PUR. The PUR search space window is located after the PUR and immediately adjacent to the PUR.

For the base station, if no uplink data is received in the PUR, the base station can use a wake-up signal to issue the indication information between the PUR and the PUR search space window, and the PUR search space window is associated with the PUR.

It should be noted that if the wake-up signal is used to issue the indication information, the base station also needs to issue the first offset or the second offset before issuing the indication information. Wherein, the first offset refers to the offset between the wake-up signal and the PUR, and the first offset may be a constant and a fixed value. The second offset is the offset between the wake-up signal and the PUR search space window, and the second offset may be a constant and a fixed value.

In a specific implementation, the indication information may simultaneously indicate whether the UE monitors the PDCCH in each of the PUR search space windows in the next multiple PUR search space windows. For example, the indication information uses N bits to indicate whether N PUR search space windows monitor the PDCCH, and N is a positive integer. N can be selected from a set of preset values. Each element of the preset value set may be pre-defined in the agreement. Assume that bit 1 indicates that the PDCCH is monitored, bit 0 indicates that the PDCCH is not monitored, and N is 4. Under this condition, "1000" means that the base station will issue the PDCCH in the PUR search space window associated with the PUR, and the UE needs to monitor the PDCCH in the PUR search space window associated with the PUR, that is, bit "1" corresponds to The PUR search space window can also be understood as the first PUR search space window after the PUR; in the following 3 consecutive PUR search space windows, the base station will not issue PDCCH, and accordingly, the UE does not need to be PDCCH is monitored in 3 consecutive PUR search space windows.

In a specific implementation, the number of the PUR search space windows is multiple, and when the indication information indicates that the terminal suspends monitoring the PDCCH in the multiple PUR search space windows, the indication information may also be used to indicate The terminal suspends receiving a wake-up signal during a plurality of the PUR search space windows. Specifically, if the base station does not issue downlink data such as PDCCH in the PUR search space window for a period of time, the base station can instruct the terminal to pause in multiple PUR search space windows in the issued instruction information Monitor the PDCCH, and inform the terminal to suspend receiving wake-up signals during multiple PUR search space windows.

It should be noted that the multiple PUR search space window periods refer to a time period including multiple PUR search space windows, and the UE does not need to receive a wake-up signal during the time period. In the first embodiment, the wake-up signal may be located between the PUR and the corresponding PUR search space window.

In a specific implementation, the base station may inform the UE of the number of PUR search space windows, for example, N PUR search space windows, N is a positive integer, and N may be selected from a set of preset values. Each element of the preset value set may be pre-defined in the agreement. After receiving the indication information, the UE can stop monitoring the PDCCH during the N PUR search space windows, and does not need to try to receive a wake-up signal during this period.

Further, in addition to instructing the terminal to suspend monitoring PDCCH and receiving wake-up signals during the plurality of PUR search space windows, the indication information may also instruct the terminal to suspend during the plurality of PUR search space windows. Send downlink beam information, where the downlink beam information includes the downlink beam that the terminal expects to use.

Fig. 2 is a schematic flowchart of a method for receiving signaling according to an embodiment of the present invention. The signaling receiving method may be executed by the terminal side, for example, executed by the UE.

Specifically, the method for receiving signaling may include step S202:

Step S202: Receive indication information, where the indication information is used to indicate whether the terminal monitors the PDCCH in the PUR search space window.

More specifically, the UE may receive indication information from the network-side base station, where the indication information is used to indicate whether the terminal monitors the PDCCH in the PUR search space window.

In a non-limiting example, before receiving the indication information, the signaling receiving method may further include step S201: sending uplink data, and the uplink data is transmitted using PUR.

Specifically, the UE is in an idle state/inactive state. The UE has uplink data to be transmitted, and the UE may send the uplink data to be transmitted to the base station in the PUR. After that, the base station may issue the indication information to notify the UE whether to monitor the PDCCH in the PUR search space window associated with the PUR.

In a specific implementation, the indication information may be carried and delivered by the ACK DCI/NACK associated with the uplink data.

In a specific implementation, the uplink data may include downlink beam information, and the downlink beam information includes a downlink beam that the terminal expects to use.

In another non-limiting example, the UE is in an idle state/inactive state. The base station may issue the indication information to the UE through a wake-up signal to inform the UE whether to monitor the PDCCH in the PUR search space window associated with the PUR.

In one embodiment, the wake-up signal is located between the PUR and the PUR search space window, and the PUR search space window is associated with the PUR.

In another non-limiting example, the UE is in an idle state/inactive state. The UE has no uplink data to be transmitted. If the base station does not receive uplink data in the PUR, the base station may then issue the indication information based on the wake-up signal to notify the UE whether to monitor the PDCCH in the PUR search space window associated with the PUR.

In one embodiment, the wake-up signal may be located between the PUR and a PUR search space window, and the PUR search space window is associated with the PUR.

It should be pointed out that, in order to receive the wake-up signal, the base station may send the first offset or the second offset to the UE before sending the indication information. Wherein, the first offset is the offset between the wake-up signal and PUR, the first offset is a fixed value, and the second offset is the wake-up signal and the PUR search space The offset between the windows, the second offset is a fixed value. After that, the UE may receive the first offset or the second offset. And receiving the wake-up signal according to the first offset or the second offset.

In a specific implementation, the number of the PUR search space windows may be multiple, and for each PUR search space window, the indication information may indicate whether the terminal monitors the PDCCH in each PUR search space window.

In a specific implementation, the number of the PUR search space windows is multiple, and when the indication information instructs the terminal to suspend monitoring the PDCCH in the multiple PUR search space windows, the indication information is also used to instruct the terminal Suspend receiving wake-up signals in multiple PUR search space windows.

Further, the indication information may also instruct the terminal to suspend sending downlink beam information within the plurality of PUR search space windows, where the downlink beam information includes the downlink beam that the terminal expects to use.

In a specific implementation, the total number of the multiple PUR search space windows is N, N is selected from a set of preset values, and N is a positive integer. The elements in the preset value set are predefined, and may be determined through negotiation between the UE and the base station, or may be set by agreement.

Those skilled in the art understand that the steps S201 to S202 can be regarded as execution steps that correspond to the steps S101 to S102 in the embodiment shown in FIG. 1, and the two are complementary to each other in terms of specific implementation principles and logic. . Therefore, for the explanation of terms and principles involved in the signaling receiving method provided in this embodiment, reference may be made to the related description of the embodiment shown in FIG. 1, which is not repeated here.

Specific embodiments are described below in detail.

Embodiment 1: The network instructs the UE to monitor the PDCCH scheduled by the downlink data through the ACK, DCI/NACK or WUS corresponding to the uplink data

Fig. 3 is a schematic flowchart of a specific implementation of an embodiment of the present invention. The network can issue downlink data scheduling information in the uplink pre-configured resource search space window. Therefore, the UE needs to periodically monitor the data scheduling PDCCH in the uplink pre-configured resource search space window. However, in many cases, the network does not have downlink data to send, and not every uplink pre-configured resource search space window has downlink scheduling information. The behavior of the UE to monitor the PDCCH periodically will cause a waste of power.

3, in order to save energy consumption of the UE, the embodiment of the present invention introduces indication information (not shown) to indicate whether the UE needs to monitor the downlink scheduling in the uplink pre-configured resource search space window (indicated by the blank dashed box in the figure) PDCCH (represented by the right striped grid). The indication information can be carried by the corresponding ACK DCI/NACK (represented by the crossed stripes in the figure) corresponding to the uplink data (that is, the uplink data sent on the uplink pre-configured resources, represented by diagonal stripes in the figure), and the UE receives ACK DCI /NACK to determine whether it is necessary to monitor the downlink scheduling PDCCH in the uplink pre-configured resource search space window.

However, the UE does not send uplink data (indicated by a blank solid line in the figure) on each uplink pre-configured resource, and there is no binding relationship between downlink data reception and uplink data transmission in terms of time. When the UE does not send uplink data on the uplink pre-configured resources, the network can issue a wake-up signal (indicated by horizontal stripes in the figure) to indicate whether the UE needs to monitor the downlink scheduling PDCCH in the uplink pre-configured resource search space window.

In other words, the behavior of the UE is: when the uplink data is sent, it determines whether it needs to monitor the downlink scheduling PDCCH in the uplink pre-configured resource search space window by receiving ACK and DCI/NACK, without detecting the wake-up signal. Otherwise, if no uplink data is sent, the UE needs to detect the wake-up signal to determine whether it needs to monitor the downlink scheduling PDCCH in the uplink pre-configured resource search space window.

In addition, the location of the wake-up signal is between the PUR and the PUR search space window. When configuring the PUR, the network can set the offset between the WUS and the PUR search space window or the difference between WUS and PUR. The offset between the two is configured to the UE together, and the UE determines the detection position of the wake-up signal through the offset.

Embodiment 2: The network indicates whether the UE needs to receive the indication information and wake-up signal and send downlink beam information through the ACK and DCI/NACK corresponding to the uplink data.

Generally, when the network sends downlink scheduling information or downlink data, it needs to determine the direction of the downlink beam. Therefore, when the UE does not send uplink data for a period of time, in order to perform downlink reception, the UE needs to report some downlink beam directions. In many cases, the network may have no downlink data to send for a long time. During this period, if the UE still performs wake-up signal detection and downlink beam information reporting, it will also cause unnecessary energy consumption. To this end, this embodiment uses the ACK and DCI/NACK corresponding to the uplink data to carry indication information, which can indicate whether the UE needs to detect a wake-up signal and whether to send downlink beam information, so as to achieve the purpose of energy saving.

FIG. 4 is a schematic flowchart of another specific implementation manner of an embodiment of the present invention. Referring to FIG. 4, in the initial stage, the UE sends PUR with data to the network, and the network can issue scheduling information such as data confirmation and/or PDCCH in the PUR search space window. After that, the UE has no data to report, and the UE can receive a wake-up signal between the PUR and the PUR search space window.

Further, the UE may report downlink beam information based on the PUR. The network side may issue ACK and DCI/NACK in the PUR search space window associated with the PUR. The ACK and DCI/NACK may carry indication information, which indicates that the wake-up signal will not be issued during the next multiple PUR search space windows.

In FIG. 4, the number of the multiple PUR search space windows is 4, and the multiple PUR search space window periods refer to the time points at which the wake-up signal can be sent between each PUR and its associated PUR search space window Or time period. Figure 4 uses “×” to indicate that the sent wake-up signal is omitted, that is, the network will not send the wake-up signal at the position/time period marked “×”. Therefore, the UE does not need to receive the wake-up signal in the corresponding time period, which can greatly save power consumption. Further, in FIG. 4, corresponding to each PUR during the multiple PUR search space windows, the UE also has no uplink data, and there is no need to send downlink beam information based on the PUR.

In summary, in the embodiment of the present invention, when the UE sends uplink data, the network can carry indication information through the ACK and DCI/NACK corresponding to the uplink data to indicate whether the UE needs to monitor the downlink scheduling in the uplink pre-configured resource space window PDCCH. Otherwise, when the UE does not send uplink data, the network may issue the indication information through a wake-up signal, and the location of the wake-up signal is between the uplink pre-configured resource and the uplink pre-configured resource search space window. In addition, the uplink data may include uplink data and downlink beam information. Through the technical solutions provided by the embodiments of the present invention, the power consumption of the terminal can be greatly saved.
