[0068] At present, saving unnecessary network energy consumption is an important means to save operating costs and achieve low carbon. By reducing unnecessary signal transmission in the time domain as much as possible and increasing the sleep opportunities of base stations in the time domain, the power consumption of base stations can be significantly saved, especially for base station no-load or low-load scenarios. In the relevant standards, cell DTX / cell DRX technology is introduced for time domain energy-saving technology; the main goal of introducing cell DTX / cell DRX is to introduce DTX / DRX enhancement, including aligning DRX or introducing some notification mechanisms to notify the terminal about the inactive state of the base station, such as the base station entering a non-sending, non-receiving state or a limited sending or receiving state. The terminal is also called user equipment (UE, User Equipment).
[0069] like Figure 1 As shown, for the cell DTX / cell DRX technology, parameters such as cell DTX / cell DRX cycle, start offset or slot offset, on duration, etc. will be introduced to determine the time position, time length, etc. of the active period and the inactive period within a cell DTX / cell DRX cycle.
[0070] In the related art, the use of PDCCH is supported to dynamically activate or deactivate cell DTX / cell DRX. The terminal receives PDCCH by detecting the candidate of PDCCH at the monitoring time of PDCCH, thereby determining whether the base station has sent PDCCH. Specifically, the base station configures a search space (SS) for PDCCH, and the terminal monitors PDCCH at the monitoring time determined according to the search space set configured by the base station, wherein at least the following parameter configurations for the terminal to monitor are configured in the search space:
[0071] The associated control channel resource set CORESET ID (control Resource Set id);
[0072] Search space type and downlink control information (DCI) format, search space type, such as common search space or UE-specific search space; DCI format includes DCI format 0_x, 1_x, 2_x, 3_x, 4_x, etc., where x is an integer;
[0073] Monitoring period and slot offset (monitoringSlotPeriodicityAndOffset);
[0074] The aggregation level and number of candidates monitored are configured through nrofCandidates;
[0075] Duration: The number of consecutive slots that a SearchSpace lasts in every occasion.
[0076] For the PDCCH used to activate or deactivate cell DTX / DRX, according to the existing search space configuration, if the terminal detects according to the periodic monitoring opportunity, there will be some unnecessary detections, resulting in increased energy consumption of the terminal. This is because when the monitoring opportunity occurs during the activation period, the terminal will continue to monitor the PDCCH regardless of whether it receives an indication to activate cell DTX / DRX or an indication to deactivate cell DTX / DRX, and the monitoring behavior of the terminal will not be affected. During the activation period of cell DTX / DRX, if the terminal encounters an inactive period of discontinuous reception (C-DRX, Connected Discontinuous Reception) in the connected state, the terminal will skip some PDCCH detections according to the rules of C-DRX. Therefore, the monitoring opportunity configuration of the PDCCH for cell DTX / DRX activation and deactivation needs to be enhanced to avoid unnecessary detection by the terminal.
[0077] In the terminal energy saving topic, the C-DRX wake-up function of the terminal is introduced. When the terminal is configured with C-DRX, the terminal wakes up periodically and enters the DRX on duration period. The timing of entering the DRX on duration period is determined by the start time of the DRX on duration timer. During the DRX on duration period, the terminal monitors the PDCCH used to schedule new data transmission. If no PDCCH for scheduling new transmission data is detected, the terminal will enter the DRX inactive period after the DRX duration timer expires. During the DRX inactive period, the terminal will no longer monitor the PDCCH for scheduling new transmission data, such as the PDCCH scrambled with the Radio Network Temporary Identity (RNTI), but will still monitor the PDCCH scrambled with the system information RNTI (SI-RNTI, System Information RNTI), random access RNTI (RA-RNTI, Radom Access RNTI), paging RNTI (P-RNTI, Paging RNTI), coding adjustment strategy RNTI (MCS-RNTI, Modulation Coding Scheme RNTI), etc. Therefore, the C-DRX mechanism can reduce the power consumption of the terminal always monitoring all PDCCHs.
[0078] The wake-up function introduced in the terminal energy saving topic indicates whether the terminal needs to start the next DRX duration timer by sending DCI control information in DCIformat 2_6 format before the DRX duration timer is started. When the base station determines that it will not transmit PDCCH to the terminal to schedule new transmission data during the next DRX duration timer, it indicates that the terminal does not need to be awakened. The terminal can skip the wake-up phase and continue to sleep, thereby reducing terminal power consumption. Monitoring of DCIformat2_6 will only occur during the terminal's dormant or inactive period, usually during the inactive period before the DRX duration timer is running. Figure 2As shown, the base station configures a time offset Ps-offset for the terminal. Ps-offset indicates the length of a period of time from the start time slot of the DRX duration timer. During this period of time, the terminal will monitor the periodic monitoring time of the length Ts time slot determined by the search space. The length of Ts is configured by the Duration of the search space configuration. In this way, the timing of monitoring DCI format 2_6 is determined. Since DCI format 2_6 is used to wake up the terminal, it is meaningful to monitor only when the terminal is in an inactive period, and only for a period of time before wake-up, the base station can pre-determine whether the terminal will be scheduled, so a period of time is determined by ps-offset.
[0079] However, the activation / deactivation signaling for cell DTX / DRX can be sent during the activation period of cell DTX / DRX or during the inactivation period, which is different from the monitoring conditions of DCI format 2_6. In order to enable the base station to respond to changes in traffic volume in a timely manner, a certain number of monitoring opportunities need to be reserved to allow the base station to adjust the activation state of cell DTX / DRX, rather than only detecting within a period of time before the DRX duration timer as in DCI format 2_6. On the other hand, according to the previous description, if the activation / deactivation signaling for cell DTX / DRX is always periodically monitored during the DRX activation period, unnecessary energy consumption will be caused to the terminal.
[0080] In summary, in the related art, when a terminal monitors a PDCCH for activating or deactivating cell DTX / DRX, some unnecessary detections occur, which wastes power consumption of the terminal.
[0081] Based on this, in each embodiment of the present application, the network device sends a first information to the terminal, and the first information is used to indicate the time period and / or the listening time of the terminal to listen to the PDCCH in the first activation period; the terminal determines the listening time of the PDCCH in the first activation period based on the received first information, and the first activation period includes the activation period of the cell DTX and / or the activation period of the cell DRX; the PDCCH carries control information for activating or deactivating the cell DTX or the cell DRX. In the above scheme, the first terminal determines the listening time of the PDCCH in the first activation period according to the first information, and thus listens to the PDCCH at the determined listening time, instead of periodically listening to all PDCCHs all the time as in the prior art, which can reduce the unnecessary monitoring of the PDCCH by the terminal and save the power consumption consumed by monitoring the PDCCH.
[0082] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0083] The present application embodiment provides a signal detection method, such as Figure 3 As shown, the method includes:
[0084] Step 301: Determine a PDCCH monitoring timing in a first activation period according to first information.
[0085] Among them, the first information is used to indicate the time period and / or monitoring time of the terminal to monitor PDCCH during the first activation period; the first activation period includes the activation period of cell DTX and / or the activation period of cell DRX; PDCCH carries control information for activating or deactivating cell DTX or cell DRX.
[0086] Here, the terminal determines the time period and / or monitoring opportunity for monitoring the PDCCH during the first activation period according to the first information; determines the monitoring opportunity of the PDCCH during the first activation period according to the determined time period and / or monitoring opportunity, so as to monitor the PDCCH at the determined monitoring opportunity. The monitoring opportunity is also called monitoring occasion. Monitoring PDCCH can be understood as detecting PDCCH or monitor PDCCH.
[0087] The first active period may be periodic or non-periodic. The first active period may be an explicitly defined active period or may refer to the period during which an on-duration timer is running.
[0088] A time period can be understood as a time window or a continuous period of time; a time period can be determined by a start time and an end time, or by a start time and a continuous period of time, or by an end time and a continuous period of time; the start time is also called the start moment, and the end time is also called the end moment. The time period can be in milliseconds (ms), slots, seconds (s), or Orthogonal Frequency Division Multiplexing (OFDM) symbols. For example, the time period can be Xms, X slots, X seconds, or X OFDM symbols.
[0089] When PDCCH is used to activate or deactivate cell DTX, PDCCH carries control information for activating or deactivating cell DTX; when PDCCH is used to activate or deactivate cell DRX, PDCCH carries control information for activating or deactivating cell DRX; the control information may include DCI in DCI format 2_x format. Cell DTX is also called cellDTX, and cell DRX is also called cell DRX.
[0090] The first information is sent by the network device. In one embodiment, the method further includes:
[0091] Receive the first information sent by the network device.
[0092] Here, the first information may be carried in a radio resource control (RRC) signaling, or a media access control (MAC) control element (CE, Control Element).
[0093] In actual application, the network device can configure a field related to cell DTX / cell DRX activation for the terminal in the PDCCH configuration (PDCCH-config), and the information carried in the field includes the first information. Optionally, the PDCCH-config can also configure a radio network temporary identifier (RNTI, Radio Network Temporary Identifier) for scrambling the PDCCH, and the RNTI can be an RNTI related to energy saving.
[0094] In order to facilitate the terminal to quickly identify the format of the DCI for activating or deactivating cell DTX or cell DRX, the network device can use a specific RNTI to scramble the PDCCH carrying the DCI for activating or deactivating cell DTX or cell DRX. Based on this, in one embodiment, the PDCCH is scrambled using a set RNTI.
[0095] In order to facilitate the terminal to determine the time window or monitoring opportunity for monitoring the PDCCH, in one embodiment, the first information includes at least one of the following:
[0096] second information, where the second information is used to instruct the terminal to monitor the PDCCH within a first time period before the end of the first activation period;
[0097] The third information is used to instruct the terminal to monitor the PDCCH in the last N monitoring periods in the first activation period, where N is a positive integer;
[0098] The fourth information is used to instruct the terminal not to monitor the PDCCH in a second time period within the first activation period, or to instruct the terminal to start monitoring the PDCCH after the second time period starting from the first activation period.
[0099] Here, when the first information includes the second information, the terminal monitors the PDCCH according to the monitoring timing configured in the search space in the first time period before the end of the first activation period. The first time period can be understood as a continuous period of time in the first activation period; the end time of the first time period can be the end time of the first activation period, or before the end time of the first activation period. For example, Figure 4 As shown, the duration length corresponding to the first time period may be Y, and the first time period starts at a time corresponding to a Y time length before the time slot corresponding to when the on duration timer expires or the timing ends, and ends at a time corresponding to the timing end of the on duration timer. That is, the terminal monitors the PDCCH according to the monitoring timing configured in the search space within a Y time length before the time slot corresponding to when the on duration timer expires or the timing ends. The on duration timer indicates a duration starting from the start position of the cell DTX cycle or the cell DRX cycle.
[0100] In the case where the first information includes the third information, the terminal monitors the PDCCH in the last N listening periods in the first activation period. The last N listening periods in the first activation period are determined by the search space configured by the network device for the PDCCH. Figure 4 As shown, the terminal monitors the PDCCH at the last N monitoring opportunities in the first activation period (or during the on duration timer). N can be 1, that is, the terminal only monitors the PDCCH at the last monitoring opportunity in the first activation period. When the search space configuration includes Duration, one monitoring opportunity may correspond to multiple consecutive time slots.
[0101] In the case where the first information includes the fourth information, the terminal starts to monitor the PDCCH according to the monitoring opportunity configured in the search space after the second time period starting from the first activation period. The second time period can be understood as a continuous period of time within the first activation period; the start time of the second time period can be the start time of the first activation period, or can be after the start time of the first activation period. For example, Figure 4 As shown, the terminal does not monitor the PDCCH within a time period of time P starting from the start time of the on duration timer of the cell DTX / cell DRX; and starts to monitor the PDCCH after a time period of time P starting from the first activation period.
[0102] In order to accurately determine the first time period, in one embodiment, the second information includes a first time length or a first offset value; wherein,
[0103] The first time period is determined according to the first time length or the first offset value contained in the first time slot and the second information; the first time slot represents the time slot corresponding to the expiration or end of the first timer; the first timer is started at the start time of each cell DTX cycle or each cell DRX cycle, or the first timer is a DTX duration timer or a DRX duration timer.
[0104] Here, the first time period can be determined by the first time slot (or the end moment of the first time slot, that is, the end moment of the first activation period) and a first time length; the first time length is a continuous time length before the end moment of the first time slot or the end moment of the first activation period, and the first time length indicates a moment that is offset by the first time length relative to the end moment of the first time slot or the end moment of the first activation period.
[0105] The first time period can also be determined by the first time slot and the first offset value; the first offset value is the offset value shifted forward from the end time of the first time slot or the end time of the first activation period, and the time corresponding to the first offset value is used as the starting time of the first time period.
[0106] That is, the first offset value indicates a time from the end moment of the first activation period or the moment (or time slot) when the first timer expires or the timing ends, at which time the terminal starts to monitor the PDCCH according to the configuration of the search space set, or starts to monitor the PDCCH at this time according to the monitoring timing determined by the search space.
[0107] The first timer may be a DTX on duration timer or a DRX on duration timer; the start time of the first timer corresponds to the start position of a time slot; the start position is the start time of the cell DTX cycle or the cell DRX cycle; the start position is determined by the cell DTX or cell DRX cycle, start-offset, slot-offset and other parameters. The expiration or timing end of the first timer can be understood as the expiration of the timer expire or the end of the active period.
[0108] For example, Figure 5 As shown, the first time length is Y; the Y value indicates a time offset time (n) before the end time of the first time slot or the first activation period. Y ), or indicates a time offset (n) before the end time of the first timer Y). The end time of the first timer can be understood as the time slot or subframe corresponding to the end of the first timer, or the end time of the time slot, the end time of the subframe, etc.
[0109] It should be noted that, when the second information includes the first time length or the first offset value, the terminal can determine the time to start detecting the PDCCH carrying DCIformat 2_x within a first activation period according to the first time slot and the Y value or the first offset value, and the specific monitoring timing of the PDCCH is still determined by the search space configuration. Figure 5 In the example, the terminal determines that the time to start monitoring the PDCCH in a first activation period is n. Y However, the first monitoring opportunity determined by the search space arrives at time n0. Therefore, the terminal starts monitoring the PDCCH from n0 during the first activation period according to the monitoring opportunity determined by the search space.
[0110] In order to facilitate the terminal to quickly determine the time period in which the PDCCH needs to be monitored, in one embodiment, the first time period starts at the second time slot and ends at the start time or the end time of the first time slot; wherein,
[0111] The time interval between the start time of the second time slot and the end time of the first time slot is greater than or equal to the first time length or the first offset value.
[0112] Here, the first time period may start at the second time slot, or start at the start time of the second time slot, and end at the first time, where the first time is the time when the first timer expires or the timing ends. The time interval between the start time of the second time slot and the first time is greater than or equal to the first time length or the first offset value.
[0113] For example, Figure 5 As shown, the first time period starts at n Y , ending at the end time of the first time slot.
[0114] It should be noted that the second time slot may be the time slot corresponding to the first time slot being offset forward by the first time length or the first offset value. That is to say, the first time period may start at the first time slot being offset forward by the first time length and end at the start time or the end time of the first time slot; the first time period may also start at the first time slot being offset forward by the first offset value and end at the start time or the end time of the first time slot.
[0115] In order to facilitate the terminal to quickly determine the monitoring period of the PDCCH, in one embodiment, the third information includes an N value, and the N value is used for the terminal to determine the last N monitoring periods during the first activation period or the operation of the first timer; wherein,
[0116] The last N listening cycles during the operation of the first timer are determined by the search space of the PDCCH; the first timer is started at the start time of each cell DTX cycle or cell DRX cycle, or the first timer is a DTX duration timer or a DRX duration timer.
[0117] Here, the N value represents the number of monitoring cycles or the number of monitoring opportunities. The N value is used to indicate the last N PDCCH monitoring cycles before the first timer expires or the timing ends. The terminal can determine the time to start monitoring the PDCCH in the first activation period according to the N value, but the specific monitoring opportunity of the PDCCH is still determined by the search space.
[0118] In order to accurately determine the second time period, in one embodiment, the fourth information includes a second time length or a second offset value; wherein,
[0119] The second time period is determined according to the second time length or the second offset value contained in the third time slot and the fourth information; the third time slot represents the time slot at which the first timer is started; the first timer is started at the start time of each cell DTX cycle or each cell DRX cycle, or the first timer is a DTX duration timer or a DRX duration timer.
[0120] Here, the second time period may be determined by the third time slot and a second time length, wherein the second time length indicates a time offset time later than a start time of the third time slot or the first activation period.
[0121] The second time period may also be determined by the third time slot and a second offset value, where the second offset value is an offset value shifted backward from the start time of the third time slot or the first activation period.
[0122] That is, the second offset value indicates a time backward from the start time of the first activation period or the start time of the first timer, at which time the terminal starts to monitor PDCCH according to the configuration of the search space set, or starts to monitor PDCCH according to the monitoring timing determined by the search space.
[0123] For example, Figure 6 As shown, the second time length is P; the P value indicates a time offset time (n) relative to the start time of the third time slot or the first activation period (or a time slot or a subframe corresponding to the start time) later. p ), or indicates a time offset relative to the end time of the first timer (n p ).
[0124] It should be noted that, when the second information includes the second time length or the second offset value, the terminal can determine the time period when not to monitor the PDCCH in a first activation period, or determine the time to start monitoring the PDCCH in a first activation period according to the third time slot, and according to the P value or the second offset value. The specific monitoring time of the PDCCH is still determined by the search space. Figure 6 In the example, the terminal determines that it does not monitor the PDCCH within a P time length after the first timer is started, and starts to monitor the PDCCH after the first timer is started and the P time length has passed. The terminal determines that the time to start monitoring the PDCCH in a first activation period is n. p However, the first monitoring opportunity determined by the search space arrives at time n0. Therefore, the terminal does not monitor the PDCCH within the P time length after the first timer is started, and starts monitoring the PDCCH from n0 during the first activation period according to the monitoring opportunity determined by the search space.
[0125] In order to facilitate the terminal to quickly determine the time period in which the PDCCH needs to be monitored, in one embodiment, the second time period starts at the third time slot and ends at the fourth time slot; wherein,
[0126] The time interval between the start time of the third time slot and the start time of the fourth time slot is greater than or equal to the second time length or the second offset value.
[0127] Here, the second time period may start at the third time slot and end at the fourth time slot; the fourth time slot may be a time slot corresponding to when the third time slot is offset backward by the second time length or the second offset value. Specifically, the second time period may start at the third time slot and end at the start time of the fourth time slot, and the end time of the fourth time slot is before the time corresponding to the end of the first timer.
[0128] The second time period may also start at the second moment and end at the third moment. The second moment is the moment when the first timer is started, or the start moment of the first timer; the time interval between the second moment and the third moment is greater than or equal to the second time length or the second offset value.
[0129] For example, Figure 6 As shown, the second time period starts at the second moment and ends at n p .
[0130] Based on the description of the above embodiment, the terminal can determine the monitoring timing of the PDCCH according to the first information during the first activation period, and the terminal can also monitor the PDCCH during the non-activation period of the cell DTX or the non-activation period of the cell DRX to improve the flexibility of the network device to activate or deactivate the cell DTX or the cell DRX. Based on this, in one embodiment, the method further includes:
[0131] In a first non-activation period, the PDCCH is monitored according to a monitoring opportunity determined by the search space; wherein the first non-activation period represents a non-activation period of the cell DTX or a non-activation period of the cell DRX.
[0132] Here, the terminal determines the monitoring opportunity in the first non-activation period according to the search space, and monitors the PDCCH at the monitoring opportunity in the first non-activation period. The first non-activation period can be understood as a period outside the cell DTX activation period, or a period or time outside the cell DRX activation period.
[0133] The following further illustrates the implementation process of the terminal monitoring the PDCCH based on the search space and the first information in conjunction with an application example.
[0134] Application example 1: The first information includes the second information, and the second information includes the first time length or the first offset value
[0135] like Figure 5 As shown, the first time length is Y, and the Y value indicates a time offset time (n) before the end time of the first time slot or the first activation period. Y ); The terminal determines that the time to start monitoring the PDCCH in a first activation period is n according to the first information Y However, since the first monitoring opportunity determined by the terminal according to the search space arrives at time n0, the terminal starts to monitor the PDCCH according to the monitoring opportunity determined by the search space from time n0 until the start time of the on duration timer of the next cellDTX / cell DRX arrives, and continues to determine the monitoring (monitoring) timing of the PDCCH in the next cell DTX cycle or cell DRX cycle according to the first information and the search space, and monitors the PDCCH according to the determined monitoring opportunity.
[0136] Application Example 2: The first information includes the third information, and the second information includes the N value
[0137] like Figure 4 As shown, the terminal determines all listening periods in the first activation period according to the search space, determines the last N listening periods among all listening periods in the first activation period according to the N value, and listens to the PDCCH at the listening moments in the determined last N listening periods; the terminal also determines all listening moments in the first non-activation period according to the search space, and monitors the PDCCH in the first non-activation period according to the listening moments in the first non-activation period.
[0138] For example, when the value of N is 1, the terminal monitors the PDCCH only at the last monitoring opportunity of the first active period, and monitors the PDCCH at the monitoring opportunity determined by the search space during the first inactive period. When the search space includes Duration, one monitoring opportunity may correspond to multiple consecutive time slots.
[0139] Application example 3: The first information includes the fourth information, and the fourth information includes the second time length or the second offset value
[0140] like Figure 6 As shown, the second time length is P, and the P value indicates a time offset time (n) relative to the start time of the third time slot or the first activation period. p ); The terminal determines that the time to start monitoring the PDCCH in a first activation period is n according to the first information p However, since the first monitoring opportunity determined by the terminal according to the search space arrives at time n0, the terminal starts to monitor the PDCCH according to the monitoring opportunity determined by the search space from n0 in a first activation period, and monitors the PDCCH according to the monitoring opportunity determined by the search space in the non-activation period corresponding to the first activation period, until the start time of the on duration timer of the next cell DTX / cell DRX arrives, and continues to determine the monitoring opportunity of the PDCCH in the next cell DTX cycle or cell DRX cycle according to the first information and the search space, and monitors the PDCCH according to the determined monitoring opportunity. In other words, the terminal starts to monitor the PDCCH according to the monitoring opportunity determined by the search space from time n0, until the start time of the on duration timer of the next cell DTX / cell DRX arrives, and then re-determines the monitoring opportunity of the PDCCH according to the first information and the search space.
[0141] The above scheme monitors PDCCH according to the first information during the first activation period, and monitors PDCCH according to the monitoring timing determined by the search space during the first non-activation period. This can not only improve the flexibility of network equipment in activating or deactivating cell DTX or cell DRX, but also reduce unnecessary monitoring of PDCCH by the terminal during the first activation period, saving power consumption consumed by monitoring PDCCH.
