Description

[0001] This application claims priority to a Chinese patent application filed with the Chinese Patent Office on July 27, 2018, with application number 201810843895.3 and invention name “Electronic device and method for wireless communication, computer-readable storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of wireless communication technology, and in particular to a discontinuous reception (DRX) technology on an unlicensed frequency band, and more particularly to an electronic device, method and computer-readable storage medium for wireless communication. Background Art

[0003] NarrowBand Internet of Things (NB-IoT) is a new wireless communication technology used to meet the needs of the Internet of Things, which can provide improved indoor coverage, support for a large number of low-throughput devices, low delay sensitivity, ultra-low device cost, low device power consumption and optimized network architecture. NB-IoT is designed for infrequent, short message delivery between user equipment (UE) and base stations, so that UE can remain cost-effective and only require a small amount of battery power. Most UEs in NB-IoT are battery-powered, so energy consumption is very important for them.

[0004] DRX is an important energy-saving mechanism. Each DRX cycle can include an activation period (On duration) and a period of time when DRX may be entered (Opportunity for DRX), such as Figure 1 When the UE is configured with DRX, it monitors and receives the Physical Downlink Control Channel (PDCCH) during the activation period, and does not monitor the PDCCH for the paging signal during the period when the UE may enter DRX, thereby achieving the purpose of reducing power consumption.

[0028] <First Embodiment>

[0029] In the case of performing DRX in the licensed band, the UE periodically detects WUS. If the UE detects WUS, it wakes up from sleep and detects the paging signal according to the paging occasion (PO) indicated by the WUS, that is, obtains the paging signal by decoding the PDCCH. Among them, WUS can indicate one or more POs in a paging frame (PF). On the other hand, if the UE does not detect WUS, the UE remains in the sleep state.

[0030] However, in the unlicensed frequency band, since the interval between the WUS and the subsequently issued PS is large, the base station may not be able to send the WUS and the corresponding PS within a maximum channel occupancy time (MCOT). After sending the WUS, since the unlicensed channel may be occupied by other devices, at the PO indicated by the WUS, the channel detection of the base station, such as Listen Before Talk (LBT), may indicate that the channel is occupied, so that the PS cannot be sent in time. In this case, the UE cannot receive the PS at the PO indicated by the WUS. In order to avoid the UE from performing unnecessary receiving operations when the unlicensed channel is busy, thereby reducing the power consumption of the UE, the present embodiment provides the following electronic device 100.

[0031] Figure 2 FIG. 1 shows a functional module block diagram of an electronic device 100 for wireless communication according to an embodiment of the present application. Figure 2 As shown, the electronic device 100 includes: an acquisition unit 101, configured to acquire a WUS from a base station when the UE performs DRX on an unlicensed frequency band, wherein the WUS includes information indicating a reception method of a PS; and a determination unit 102, configured to determine an operation of the user equipment to receive the PS based on the WUS.

[0032] The acquisition unit 101 and the determination unit 102 may be implemented by one or more processing circuits, which may be implemented as a chip, for example. Figure 2 The various functional units in the device shown in the figure are only logical modules divided according to the specific functions implemented by them, and are not used to limit the specific implementation method. This also applies to the examples of other electronic devices to be described later.

[0033] The electronic device 100 can be arranged on the UE side or can be communicatively connected to the UE, for example. Here, it should also be pointed out that the electronic device 100 can be implemented at the chip level, or it can also be implemented at the device level. For example, the electronic device 100 can work as a user device itself, and can also include external devices such as a memory, a transceiver (not shown in the figure), etc. The memory can be used to store programs and related data information that need to be executed by the user device to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (for example, base stations, other user devices, etc.), and the implementation form of the transceiver is not specifically limited here.

[0034] In DRX mode, for example, when the base station needs to transmit data to the UE, it first sends a wake-up signal WUS to wake up the UE from the sleep state so that subsequent data reception can be performed. WUS can be received in the Radio Resource Control (RRC) connected RRC connected state or in the RRC Idle state. In addition, WUS can also support measurement functions, such as acting as a reference signal, thereby reducing the power consumption of the user equipment caused by additional measurements of other signals.

[0035] In addition, the WUS may be transmitted via a UE specific PDCCH or via a group based PDCCH. In both cases, the WUS may be included in downlink control information (DCI).

[0036] As mentioned above, the WUS includes an indication of the time PO for receiving the PS. When the UE in the sleep state successfully receives the WUS, it can be known when the PS should be detected. For example, the UE decodes the PDCCH at the indicated PO to detect the PS. The WUS in this embodiment includes information indicating the reception method of the PS. Based on this information, the UE can receive the PS in a more flexible manner, thereby further reducing power consumption.

[0037] In addition, the WUS may also include information indicating whether to receive the PS. After the acquisition unit 101 acquires the WUS, the determination unit 102 determines the operation of the user equipment to receive the PS based on the WUS.

[0038] For example, the information indicating the receiving mode of the PS in the WUS includes indication information of a predetermined restriction strategy to be adopted, and the predetermined restriction strategy is used to limit the number of detection times of the PS. It can be understood that when the number of detection times of the PS is limited, unnecessary detection of the PS can be avoided when the unlicensed channel is busy, thereby reducing the power consumption of the UE.

[0039] In one example, the indication information of the predetermined restriction strategy may include an information bit indicating whether to use the predetermined restriction strategy. In this case, the base station and the user equipment are aware of the predetermined restriction strategy in advance, and therefore, only one bit of information bit is needed to indicate whether the predetermined restriction strategy will be applied. For example, when the value of the information bit is "1", it indicates that the predetermined restriction strategy is to be applied, and when the information bit is "0", it indicates that the predetermined restriction strategy is not to be applied. Alternatively, the indication information of the predetermined restriction strategy may include the designation of the parameters involved in the predetermined restriction strategy.

[0040] In addition, in the case where there are multiple predetermined restriction strategies, the indication information of the predetermined restriction strategy may also include the designation of a specific predetermined restriction strategy to be adopted.

[0041] As an example, the predetermined restriction strategy includes a back-off strategy, and the determination unit 102 is configured to wait for a time determined by the back-off strategy before performing a second detection when the first detection of the PS fails. The waiting is called back-off, wherein the failure to detect the PS means that the PS is not detected, that is, the PDCCH is not successfully decoded. It should be understood that the first and second times described here are only to indicate the order of precedence, rather than the first and second times in an absolute sense.

[0042] As mentioned above, the WUS may also include the position and number of POs for detecting PS in the paging frame. For example, when the determination unit 102 fails to detect PS at the first PO, it does not detect at the next second PO, but skips the second PO or more POs and detects PS at the later POs. In this example, the time to wait may be represented by the number of POs for detecting PS in the paging frame. For example, the fallback strategy includes determining the time to wait in a random manner or according to a predetermined rule.

[0043] In the case of randomly determining the waiting time, the determination unit 102 randomly selects n from the set {0, 1, 2, ..., K}, for example, and waits for 2 n After the PO, the second n PS detection was performed at +1 PO.

[0044] When the waiting time is determined according to a predetermined rule, for example, the waiting time can be determined according to the number of failed PS detections. If k represents the number of failed PS detections, then the waiting time can be 2 seconds when the kth failure occurs. k-1 After the PO, the second k-1 The PS is detected at +1 PO. Of course, this is only an example of a predetermined rule, and various predetermined rules can be adopted as needed, without limitation thereto.

[0045] For ease of understanding, Figure 3 FIG. 4 is a schematic diagram showing a PS detection in which the waiting time is randomly determined. Figure 3 As shown, there is a certain interval between the reception of WUS and PO. The UE performs PS detection at the first PO after the interval, but the detection fails (indicated by diagonal lines in the figure). The determination unit 102 randomly selects n=0, so it backs off 1 PO and performs PS detection again. The second PS detection still fails, and the determination unit 102 randomly selects n=1, so it backs off 2 POs and performs PS detection again. The third PS detection fails, and the determination unit 102 randomly selects n=0, so it backs off 1 PO and performs PS detection again, and finally successfully detects PS at the 8th PO (indicated by gray filling in the figure).

[0046] It can be seen that if the conventional method is followed, an attempt is made to detect the PS at each PO, which requires 8 detections. However, by adopting the fallback strategy of the present application, only 4 detections are required to successfully detect the PS, effectively reducing the power consumption of the UE.

[0047] In addition, the determining unit 102 is further configured to stop detecting the PS and make the UE enter a sleep state to wait for the next WUS if no PS is detected in a paging frame.

[0048] In another example, the predetermined restriction policy may include setting a counter for counting the number of failed PS detections, and the determination unit 102 is configured to stop detecting PSs and cause the UE to enter a sleep state when the count of the counter reaches a predetermined threshold.

[0049] The predetermined threshold may be set to be smaller than the number of POs used to detect PS in the paging frame. Figure 4 FIG. 4 is a schematic diagram showing PS detection in the case where a counter is used as a predetermined limiting strategy. Figure 4 In the example, WUS indicates that there are 5 POs, and the UE performs PS detection at these POs in sequence, and the predetermined threshold is set to 3. Therefore, each time the PS detection fails, the counter is increased by 1. When the PS detection fails three times, the count value of the counter reaches 3, and the UE stops PS detection, resets the counter and goes to sleep.

[0050] Furthermore, the determination unit 102 is further configured to reset the counter when a PS is detected when the count of the counter does not reach a predetermined threshold.

[0051] When the unlicensed channel is busy, after the base station sends the WUS, it may not be able to send the PS for a period of time because the channel detection indicates that the channel is occupied by other devices. In this case, the UE obviously cannot detect the PS. In order to avoid unnecessary detection operations, in this example, the busy state of the channel is determined by setting a counter, so as to stop the PS detection and reduce the power consumption of the UE.

[0052] In another example, the predetermined restriction policy may include a fallback policy and a counter, that is, the predetermined restriction policies in the above two examples may be used in combination. In this case, the determination unit 102 may be configured to wait for a time determined by the fallback policy before performing a second detection when the first detection of the PS fails, the counter is used to count the number of failures in detecting the PS, and the determination unit 102 is configured to stop detecting the PS and cause the UE to enter a sleep state when the count of the counter reaches a predetermined threshold.

[0053] By combining the two strategies, power consumption can be more effectively reduced while increasing the probability of detecting PS. It should be understood that although NB-IoT is listed as an example of an application scenario in the foregoing text, the technology proposed in this application is not limited to this scenario, but can be applied to any occasion where WUS needs to be received.

[0054] <Second Embodiment>

[0055] Figure 5 A functional module block diagram of an electronic device 200 for wireless communication according to another embodiment of the present application is shown. Figure 5 As shown, the electronic device 200 includes: a generating unit 201, configured to generate a WUS containing information indicating a reception mode of a PS, the WUS being used to wake up a UE in a dormant state in a discontinuous reception mode operating in an unlicensed frequency band; and a sending unit 202, configured to send the WUS to the UE in the unlicensed frequency band.

[0056] Similarly, the generating unit 201 and the sending unit 202 may be implemented by one or more processing circuits, which may be implemented as a chip, for example. Figure 5 The various functional units in the device shown in the figure are only logical modules divided according to the specific functions implemented by them, and are not used to limit the specific implementation method.

[0057] The electronic device 200 can be arranged on the base station side or can be communicatively connected to the base station. Here, it should also be noted that the electronic device 200 can be implemented at the chip level, or it can also be implemented at the device level. For example, the electronic device 200 can work as the base station itself, and can also include external devices such as memory, transceiver (not shown). The memory can be used to store programs and related data information that need to be executed by the base station to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (e.g., user equipment, other base stations, etc.), and the implementation form of the transceiver is not specifically limited here.

[0058] The electronic device 200 of this embodiment is used to send a WUS to the UE, so as to configure the way in which the UE receives PS using the WUS. In addition, the WUS may also include information indicating whether the UE is to receive PS. The WUS also includes the position and number of POs used to detect PS in the paging frame.

[0059] After sending WUS, the base station will send PS to the UE according to the timing of PO, such as Figure 3 and Figure 4 As shown, there is a certain interval between the sending of WUS and the sending of PS. For example, the sending unit 202 is configured to send a paging frame including the PS via PDCCH after sending WUS. However, in the unlicensed frequency band, since the base station may not be able to access the channel at the timing of PO, there may be a situation where some PS transmissions fail due to channel busyness. By including information indicating the reception method of PS in the wake-up signal, the UE can receive the PS in a flexible manner, thereby reducing the energy consumption of the UE.

[0060] For example, the information indicating the reception mode of the PS includes information of a predetermined restriction strategy to be adopted by the UE, and the predetermined restriction strategy is used to limit the number of detection times of the paging signal. In one example, the indication information of the predetermined restriction strategy includes an information bit indicating whether the predetermined restriction strategy is used. The specific description of the indication information of the predetermined restriction strategy has been given in the first embodiment and will not be repeated here.

[0061] In one example, the predetermined restriction policy includes a fallback policy, wherein, when the UE fails to detect the PS for the first time, it waits for a time determined by the fallback policy before performing a second detection. The fallback policy includes determining the waiting time in a random manner or according to a predetermined rule, and the waiting time can be represented by the number of POs used to detect the PS in the paging frame. For example, the fallback policy includes determining the waiting time according to the number of failed detections of the PS.

[0062] In another example, the predetermined restriction policy includes setting a counter, the counter is used to count the number of failures of the UE to detect the PS, wherein the UE stops detecting the PS and enters a sleep state when the count of the counter reaches a predetermined threshold. For example, the WUS may also include setting information of the predetermined threshold. The predetermined threshold is less than the number of POs used to detect the PS in the paging frame.

[0063] In another example, the predetermined restriction policy may include both a backoff policy and a setting of a counter, wherein, when the UE fails in the first detection of the PS, the UE waits for a time determined by the backoff policy before performing a second detection, and the counter is used to count the number of failed attempts to detect the PS, and the UE stops detecting the PS and goes into sleep mode when the count of the counter reaches a predetermined threshold.

[0064] The detailed description of the predetermined restriction strategy in the above example has been given in the first embodiment and will not be repeated here.

[0065] According to the present embodiment, the electronic device 200 includes information indicating the PS reception method in the WUS, so that the UE can receive the PS in a flexible manner, for example, avoiding performing unnecessary reception operations, thereby reducing power consumption.

[0066] <Third Embodiment>

[0067] In the process of describing the electronic device for wireless communication in the above embodiments, it is obvious that some processes or methods are also disclosed. Below, an overview of these methods is given without repeating some of the details discussed above, but it should be noted that although these methods are disclosed in the process of describing the electronic device for wireless communication, these methods do not necessarily use the components described or are not necessarily performed by those components. For example, the embodiments of the electronic device for wireless communication can be partially or completely implemented using hardware and / or firmware, and the methods for wireless communication discussed below can be completely implemented by a computer executable program, although these methods can also use the hardware and / or firmware of the electronic device for wireless communication.

[0068] Figure 6 A flow chart of a method for wireless communication according to an embodiment of the present application is shown. Figure 6 As shown, the method includes: when the UE performs DRX on an unlicensed frequency band, obtaining a WUS from a base station (S11), wherein the WUS includes information indicating a receiving method of a paging signal; and determining an operation of the user equipment to receive the paging signal based on the WUS (S12). The method can be performed on the user equipment side.

[0069] The WUS may also include the position and number of paging times for detecting paging signals in the paging frame. The WUS may also include information indicating whether to receive the PS. The WUS may be received in the sleep state of the UE.

[0070] For example, the information indicating the receiving mode of the paging signal includes the indication information of the predetermined restriction strategy to be adopted, and the predetermined restriction strategy is used to limit the number of detection times of the paging signal. For example, the indication information of the predetermined restriction strategy may include an information bit indicating whether to use the predetermined restriction strategy.

[0071] Exemplarily, in step S12, the predetermined restriction strategy includes a fallback strategy, wherein, in the case of a first detection failure of the paging signal, a second detection is performed after waiting for a time determined by the fallback strategy. For example, the paging signal is detected by decoding the PDCCH. The fallback strategy includes determining the time to wait in a random manner or according to a predetermined rule, wherein the time to wait can be represented by the number of paging moments for detecting the paging signal in the paging frame. For example, the fallback strategy includes determining the time to wait according to the number of failed detections of the paging signal.

[0072] If no paging signal is detected in a paging frame, the detection of the paging signal is stopped and the user equipment is caused to enter a sleep state.

[0073] In addition, the predetermined restriction strategy may include setting a counter, the counter being used to count the number of failures in detecting the paging signal, and stopping detecting the paging signal and causing the user equipment to enter a sleep state when the count of the counter reaches a predetermined threshold. The predetermined threshold is, for example, less than the number of paging moments used to detect the paging signal in the paging frame.

[0074] In the case where a paging signal is detected when the count of the counter does not reach a predetermined threshold, the counter is reset.

[0075] In addition, the predetermined restriction strategy may include both a backoff strategy and setting a counter, wherein, in the event that the first detection of the paging signal fails, a second detection is performed after waiting for a time determined by the backoff strategy, and the counter is used to count the number of failed attempts to detect the paging signal. When the count of the counter reaches a predetermined threshold, the detection of the paging signal is stopped and the user device is put into a sleep state.

[0076] Figure 7 A flow chart of a method for wireless communication according to an embodiment of the present application is shown. Figure 7 As shown, the method includes: generating a wake-up signal (S21) including information indicating a receiving mode of a paging signal, the wake-up signal being used to wake up a user equipment in a sleep state in a DRX mode operating in an unlicensed frequency band; and sending the wake-up signal to the user equipment in the unlicensed frequency band (S22). The method can be performed at a base station side.

[0077] The information indicating the receiving mode of the paging signal includes the indication information of the predetermined restriction strategy to be adopted by the user equipment, and the predetermined restriction strategy is used to limit the number of detection times of the paging signal. The indication information of the predetermined restriction strategy may include an information bit indicating whether to use the predetermined restriction strategy.

[0078] The predetermined restriction policy includes a fallback policy, wherein the user equipment waits for a time determined by the fallback policy before performing a second detection when the first detection of the paging signal fails. The fallback policy includes determining the waiting time in a random manner or according to a predetermined rule, wherein the waiting time is represented by the number of paging moments used to detect the paging signal in the paging frame. For example, the fallback policy includes determining the waiting time according to the number of failed detections of the paging signal.

[0079] The predetermined restriction strategy may include setting a counter for counting the number of failures of the user equipment to detect the paging signal, wherein the user equipment stops detecting the paging signal and enters a sleep state when the count of the counter reaches a predetermined threshold. The predetermined threshold is less than the number of paging moments used to detect the paging signal in the paging frame.

[0080] In addition, the predetermined restriction strategy may also include a backoff strategy and a counter setting, wherein, when the user equipment fails in the first detection of the paging signal, the user equipment waits for a time determined by the backoff strategy before performing a second detection, and the counter is used to count the number of failed attempts to detect the paging signal. When the count of the counter reaches a predetermined threshold, the user equipment stops detecting the paging signal and goes into sleep mode.

[0081] After sending the wake-up signal, a paging frame including a paging signal may be sent via the physical downlink control channel.

[0082] Note that the above methods may be used in combination or individually, and the details thereof have been described in detail in the first to second embodiments and will not be repeated here.

[0083] The technology of the present disclosure can be applied to various products.

[0084] For example, the electronic device 200 may be implemented as various base stations. The base station may be implemented as any type of evolved Node B (eNB) or gNB (5G base station). eNBs include, for example, macro eNBs and small eNBs. Small eNBs may be eNBs that cover cells smaller than macro cells, such as pico eNBs, micro eNBs, and home (femto) eNBs. Similar situations may also apply to gNBs. Alternatively, the base station may be implemented as any other type of base station, such as a NodeB and a base transceiver station (BTS). The base station may include: a main body (also referred to as a base station device) configured to control wireless communications; and one or more remote radio heads (RRHs) arranged in a different place from the main body. In addition, various types of user equipment may work as a base station by temporarily or semi-permanently performing base station functions.

[0085] The electronic device 100 may be implemented as various user devices. The user device may be implemented as a mobile terminal (such as a smart phone, a tablet personal computer (PC), a notebook PC, a portable game terminal, a portable / dongle-type mobile router, and a digital camera) or a vehicle-mounted terminal (such as a car navigation device). The user device may also be implemented as a terminal for performing machine-to-machine (M2M) communication (also referred to as a machine type communication (MTC) terminal). In addition, the user device may be a wireless communication module (such as an integrated circuit module including a single chip) installed on each of the above-mentioned terminals.

[0086] [Application examples for base stations]

[0087] (First application example)

[0088] Figure 8800 is a block diagram showing a first example of a schematic configuration of an eNB or gNB to which the technology of the present disclosure can be applied. Note that the following description takes eNB as an example, but can also be applied to gNB. The eNB 800 includes one or more antennas 810 and a base station device 820. The base station device 820 and each antenna 810 can be connected to each other via an RF cable.

[0089] Each of the antennas 810 includes a single or multiple antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used for the base station device 820 to transmit and receive wireless signals. Figure 8 As shown, the eNB 800 may include multiple antennas 810. For example, the multiple antennas 810 may be compatible with multiple frequency bands used by the eNB 800. Figure 8 An example is shown in which the eNB 800 includes a plurality of antennas 810 , but the eNB 800 may also include a single antenna 810 .
