The method of the embodiment of the application can be applied to a 5G NR system and can also be applied to other communication scenes. The 5G NR system further increases the system bandwidth on the basis of 4G. For example, in a 5G NR system, for a frequency band below 6GHz, the maximum bandwidth supported by a single carrier is 100 MHz; for the frequency band above 6GHz, the maximum bandwidth supported by a single carrier is 400 MHz. However, for a large carrier bandwidth, for example, 100MHz, the bandwidth used by the terminal device is often limited, and if the terminal device is allowed to perform signal detection and measurement on the whole bandwidth all the time, the power consumption of the terminal device will be very large, which is not favorable for saving power of the terminal device. Therefore, in the 5G NR system, a Bandwidth Part (BWP) occurs, that is, a Part of continuous Bandwidth is divided into a whole large carrier Bandwidth for data transmission and reception to and from the terminal device. For example, for each serving cell of the terminal device, the network device may configure the terminal device with one or more BWPs within the serving cell, e.g., up to 4 BWPs may be configured. At each time, the terminal has an active Downlink (DL) BWP and an active uplink (Up Link, UL) BWP in the serving cell, and the terminal device receives data on the active DL BWP and transmits data on the active UL BWP. The DL BWP and UL BWP may be the same BWP or different BWPs.
Generally, a terminal device needs to obtain downlink or uplink scheduling information according to information carried in a PDCCH channel issued by a network device, and further, complete data transceiving according to the downlink or uplink scheduling information. However, the terminal device does not know whether the network device transmits information carried by the PDCCH, and therefore, the terminal device needs to perform blind detection on the PDCCH. In general, a PDCCH resource set that the terminal device needs to perform blind detection is recorded as a search space, each search space corresponds to a monitoring period, and the monitoring period is configured by the network device in a semi-static manner, which results in large power consumption of the terminal device and is not beneficial to energy saving of the terminal device. In order to solve the problem, this embodiment provides a resource set monitoring method, and the following describes the resource set monitoring method with reference to a specific embodiment.
Fig. 2 is a flowchart of a resource set monitoring method provided in the present application. The method can be applied to terminal equipment. As shown in fig. 2, the resource set monitoring method includes the following steps:
step S201, receiving indication information sent by a network device, where the indication information is used to indicate the adjusted listening period of the terminal device.
In this embodiment, the network device may dynamically adjust the monitoring period of the terminal device monitoring the PDCCH according to the information such as the characteristics of the service data of the terminal device, the scheduling interval of the scheduling information, and the network load. For example, when the delay of the traffic data of the terminal device is small and/or the scheduling interval of the scheduling information is small, the network device may adjust the monitoring period for the terminal device to monitor the PDCCH to be smaller. Or, when the delay of the service data of the terminal device is large and/or the scheduling interval of the scheduling information is large, the network device may adjust the monitoring period for the terminal device to monitor the PDCCH to be larger. It can be understood that, here, the network device is not limited to dynamically adjust the monitoring period for the terminal device to monitor the PDCCH according to the characteristics of the service data of the terminal device, the scheduling interval of the scheduling information, the network load, and the like, and in other embodiments, the network device may also dynamically adjust the monitoring period for the terminal device to monitor the PDCCH according to other methods, for example, the network device may periodically and dynamically adjust the monitoring period for the terminal device to monitor the PDCCH.
In this embodiment, when the network device needs to dynamically adjust the monitoring period for the terminal device to monitor the PDCCH, the network device may send indication information to the terminal device, where the indication information is used to indicate the adjusted monitoring period of the terminal device. Accordingly, the terminal device receives the indication information.
Step S202, monitoring the corresponding resource set in the adjusted monitoring period.
After receiving the indication information, the terminal device may monitor the PDCCH in the adjusted monitoring period.
For example, the terminal device monitors the PDCCH at present for a short period, and initiates a downlink service with a large packet transmission interval. The network equipment can dynamically adjust the monitoring period of the terminal equipment for monitoring the PDCCH according to the packet sending interval of the business service, so that the monitoring period of the terminal equipment for monitoring the PDCCH is longer. After dynamically adjusting the monitoring period, the network device sends indication information to the terminal device, where the indication information is used to indicate the adjusted monitoring period of the terminal device. After receiving the indication information, the terminal device monitors the PDCCH according to the adjusted monitoring period, i.e. the larger monitoring period.
In the resource set monitoring method provided by this embodiment, the terminal device receives the indication information, which is sent by the network device and used for indicating the adjusted monitoring period of the terminal device, so that the terminal device can monitor the corresponding resource set in the adjusted monitoring period, and thus the monitoring period in which the terminal device monitors the resource set can be dynamically adjusted, power consumption of the terminal device is reduced, and electric quantity of the terminal device is saved.
In this embodiment, before receiving the indication information sent by the network device, the method further includes: receiving configuration information sent by the network device, where the configuration information is used to configure at least one working bandwidth for the terminal device, where each working bandwidth in the at least one working bandwidth corresponds to at least one search space, and each search space in the at least one search space corresponds to at least one listening period. Optionally, each working bandwidth of the at least one working bandwidth corresponds to at least one control resource set, and each control resource set of the at least one control resource set corresponds to at least one search space.
For example, the network device sends Radio Resource Control (RRC) configuration information to the terminal device, and the network device configures at least one DL BWP for the terminal device through the RRC configuration information, and configures at least one Control-Resource set (core) for each DL BWP in the at least one DL BWP, where each core in the at least one core set corresponds to at least one PDCCH search space, and each PDCCH search space in the at least one PDCCH search space corresponds to at least one PDCCH monitoring period. Wherein, different PDCCH search spaces correspond to different or the same PDCCH monitoring periods.
In one possible implementation manner, the network device may adjust the PDCCH monitoring period of the terminal device by adjusting the PDCCH search space of the terminal device. Specifically, the indication information received by the terminal device and sent by the network device is first indication information, and the first indication information is used for indicating the adjusted target search space; correspondingly, the terminal device monitors the corresponding resource set in at least one monitoring period corresponding to the target search space.
For example, the network device configures two DL BWPs, which are denoted as DL BWP1 and DL BWP2, respectively, with DL BWP1 currently activated, and DL BWP1 configures two PDCCH search spaces, e.g., PDCCH search space 1 and PDCCH search space 2, where 1 and 2 are identification information of the two PDCCH search spaces. For example, a PDCCH search space 1 corresponds to a PDCCH monitoring period of 2 slots (slots), and a PDCCH search space 2 corresponds to a PDCCH monitoring period of 4 slots. The currently activated PDCCH search space is PDCCH search space 1, that is, the terminal device currently monitors the PDCCH using a PDCCH monitoring period of 2 slots corresponding to PDCCH search space 1. In order to adjust the PDCCH monitoring period of the terminal device to be larger, the network device may send first indication information to the terminal device, where the first indication information is used to indicate that the adjusted target search space is PDCCH search space 2. For example, the first indication information includes identification information of the PDCCH search space 2. And after receiving the first indication information, the terminal device activates the target search space, namely the PDCCH search space 2, and monitors the PDCCH in a PDCCH monitoring period of 4 time slots corresponding to the PDCCH search space 2.
As shown in fig. 3, before time t1, the terminal device monitors the PDCCH in the search space corresponding to the monitoring period of 2 slots. At time t1, the terminal device receives the first indication information, and the first indication information indicates that the adjusted target search space is a search space corresponding to a PDCCH monitoring period of 4 slots. Therefore, the terminal device monitors the PDCCH in the search space corresponding to the PDCCH monitoring period of 4 slots from time t 1.
The above embodiments are schematically illustrated by taking an example that one PDCCH search space corresponds to one PDCCH monitoring period. In some scenarios, one PDCCH search space may correspond to multiple PDCCH monitoring periods. For example, PDCCH search space 2 corresponds to 3 PDCCH monitoring periods, which are a PDCCH monitoring period of 2 slots, a PDCCH monitoring period of 4 slots, and a PDCCH monitoring period of 8 slots, respectively. When the terminal device receives the first indication information, where the first indication information includes identification information of the PDCCH search space 2, the terminal device may have the following processing manners:
one possible way is: the terminal device monitors the PDCCH in each of the 3 PDCCH monitoring periods corresponding to the PDCCH search space 2. For example, the terminal device monitors the PDCCH in a PDCCH monitoring period of 2 slots, a PDCCH monitoring period of 4 slots, and a PDCCH monitoring period of 8 slots.
Yet another possible way is: the terminal device does not monitor the PDCCH in each PDCCH monitoring period of the 3 PDCCH monitoring periods corresponding to the PDCCH search space 2.
Yet another possible way is: the terminal device monitors the PDCCH in a default monitoring period of the 3 PDCCH monitoring periods corresponding to the PDCCH search space 2. Optionally, the network device may pre-configure the terminal device with a default monitoring period corresponding to the PDCCH search space, or the network device may indicate the default monitoring period corresponding to the PDCCH search space to the terminal device through the dedicated indication information, for example, the network device may pre-configure the terminal device with a default monitoring period corresponding to each PDCCH search space. For example, the PDCCH search space 2 corresponds to a default monitoring period that is a PDCCH monitoring period of 8 slots, and therefore, when the terminal device receives the first indication information and the first indication information includes the identification information of the PDCCH search space 2, the terminal device monitors the PDCCH in the PDCCH monitoring period of 8 slots.
In another possible implementation manner, the network device may directly adjust the PDCCH monitoring period of the terminal device. Specifically, the indication information received by the terminal device and sent by the network device is second indication information, and the second indication information is used for indicating the adjusted target monitoring period; correspondingly, the terminal device monitors the corresponding resource set in the target monitoring period corresponding to the currently activated search space.
For example, the network device configures the terminal device with two DL BWPs, which are denoted as DL BWP1 and DL BWP2, respectively, and currently activated is DL BWP1, and DL BWP1 is configured with two PDCCH search spaces, e.g., PDCCH search space 1 and PDCCH search space 2. The currently activated PDCCH search space 2 corresponds to 3 PDCCH monitoring periods, and the identification information of the 3 PDCCH monitoring periods is 1,2, and 3 respectively, where the PDCCH monitoring period 1 is 2 slots, the PDCCH monitoring period 2 is 4 slots, and the PDCCH monitoring period 3 is 8 slots. The terminal device currently monitors the PDCCH in PDCCH monitoring period 1, i.e. 2 slots of PDCCH monitoring period. In order to adjust the PDCCH monitoring period of the terminal device to be larger, the network device may send second indication information to the terminal device, where the second indication information is used to indicate that the adjusted target monitoring period is the PDCCH monitoring period 2, and for example, the second indication information includes identification information of the PDCCH monitoring period 2. And after receiving the second indication information, the terminal device activates PDCCH monitoring period 2, and monitors the PDCCH in PDCCH monitoring period 2 corresponding to the currently activated PDCCH searching space, i.e. PDCCH searching space 2, i.e. PDCCH monitoring period of 4 time slots.
In yet another possible implementation, the network device may adjust a PDCCH search space and a PDCCH monitoring period of the terminal device. Specifically, the indication information received by the terminal device and sent by the network device is first indication information and second indication information, the first indication information is used for indicating the adjusted target search space, and the second indication information is used for indicating the adjusted target monitoring period; correspondingly, the terminal device monitors the corresponding resource set in the target monitoring period corresponding to the target search space.
For example, the DL BWP currently activated by the terminal device is DL BWP1, and DL BWP1 is configured with two PDCCH search spaces, e.g., PDCCH search space 1 and PDCCH search space 2. The PDCCH search space 1 corresponds to one PDCCH monitoring period, which is 2 slots. The PDCCH search space 2 corresponds to 3 PDCCH monitoring periods, and the identification information of the 3 PDCCH monitoring periods is 1,2, and 3, respectively, where the PDCCH monitoring period 1 is 2 slots, the PDCCH monitoring period 2 is 4 slots, and the PDCCH monitoring period 3 is 8 slots. The currently activated PDCCH search space is PDCCH search space 1, that is, the terminal device currently monitors the PDCCH using a PDCCH monitoring period of 2 slots corresponding to PDCCH search space 1. In order to adjust the PDCCH monitoring period of the terminal device to be larger or due to BWP change, the network device may send first indication information and second indication information to the terminal device at the same time, or send the first indication information and the second indication information to the terminal device at different times, where the first indication information is used to indicate that the adjusted target search space is the PDCCH search space 2, and the second indication information is used to indicate that the adjusted target monitoring period is the PDCCH monitoring period 2. After receiving the first indication information and the second indication information, the terminal device activates PDCCH search space 2 and PDCCH monitoring period 2, and monitors the PDCCH in PDCCH monitoring period 2 corresponding to PDCCH search space 2, that is, PDCCH monitoring period of 4 slots.
In yet another possible implementation manner, the network device may adjust the PDCCH monitoring period of the terminal device by adjusting the core set of the terminal device. Specifically, the indication information received by the terminal device and sent by the network device is third indication information, where the third indication information is used to indicate the adjusted target control resource set; correspondingly, the terminal device monitors the corresponding resource set in at least one monitoring period in at least one search space corresponding to the target control resource set.
For example, the DL BWP currently activated by the terminal device is DL BWP1, and DL BWP1 has two CORESET, denoted CORESET1 and CORESET 2. Where, the CORESET1 corresponds to one PDCCH search space, for example, PDCCH search space 1. The PDCCH search space 1 corresponds to a PDCCH monitoring period, for example, PDCCH monitoring period 1, and the PDCCH monitoring period 1 is 2 slots. The CORESET2 corresponds to one PDCCH search space, for example, PDCCH search space 2, the PDCCH search space 2 corresponds to one PDCCH monitoring period, for example, PDCCH monitoring period 2, and the PDCCH monitoring period 2 is 4 slots.
The currently activated CORESET is CORESET1, that is, the terminal device currently monitors the PDCCH in PDCCH monitoring period 1 of PDCCH search space 1 corresponding to CORESET 1. In order to adjust the PDCCH monitoring period of the terminal device to be larger, the network device may send third indication information to the terminal device, where the third indication information is used to indicate that the adjusted target CORESET is CORESET2, and for example, the third indication information includes identification information of CORESET 2. When the terminal device receives the third indication information, it activates CORESET2, and monitors PDCCH in PDCCH monitoring period 2 of PDCCH search space 2 corresponding to CORESET 2.
The above embodiment is schematically illustrated by taking an example that one CORESET corresponds to one PDCCH search space, and one PDCCH search space corresponds to one PDCCH monitoring period. In some scenarios, one core may correspond to multiple PDCCH search spaces, and one PDCCH search space may also correspond to multiple PDCCH monitoring periods. For example, CORESET2 corresponds to two PDCCH search spaces, PDCCH search space 2 and PDCCH search space 3, respectively. The PDCCH search space 2 corresponds to 3 PDCCH monitoring periods, which are PDCCH monitoring period 2, PDCCH monitoring period 3, and PDCCH monitoring period 4, respectively. The PDCCH search space 3 corresponds to two PDCCH monitoring periods, namely a PDCCH monitoring period 5 and a PDCCH monitoring period 6. In this scenario, when the terminal device receives the third indication information, where the third indication information includes identification information of CORESET2, the terminal device may have the following processing manners:
one possible way is: the terminal device monitors PDCCH in a plurality of PDCCH monitoring periods corresponding to each of the two PDCCH search spaces corresponding to the CORESET2, for example, the terminal device monitors PDCCH in PDCCH monitoring period 2, PDCCH monitoring period 3, PDCCH monitoring period 4, PDCCH monitoring period 5, and PDCCH monitoring period 6.
Another possible way is: the terminal device does not monitor the PDCCH in multiple PDCCH monitoring periods corresponding to each of the two PDCCH search spaces corresponding to the CORESET2, for example, the terminal device does not monitor the PDCCH in PDCCH monitoring period 2, PDCCH monitoring period 3, PDCCH monitoring period 4, PDCCH monitoring period 5, and PDCCH monitoring period 6.
Yet another possible way is: the terminal device monitors PDCCHs in a plurality of PDCCH monitoring periods corresponding to a default search space of the two PDCCH search spaces corresponding to the CORESET2, for example, if the default search space corresponding to the CORESET2 is PDCCH search space 3, the terminal device monitors PDCCHs in PDCCH monitoring period 5 and PDCCH monitoring period 6.
Yet another possible way is: the terminal device monitors the PDCCH in a default monitoring period corresponding to a default search space of the two PDCCH search spaces corresponding to the CORESET 2. For example, if the default search space corresponding to the CORESET2 is PDCCH search space 3, and the default monitoring period corresponding to the PDCCH search space 3 is PDCCH monitoring period 5, the terminal device monitors PDCCH in PDCCH monitoring period 5.
Yet another possible way is: the terminal device monitors the PDCCH in a default monitoring period corresponding to each of the two PDCCH search spaces corresponding to the CORESET 2. For example, if the default monitoring period corresponding to the PDCCH search space 2 is PDCCH monitoring period 3, and the default monitoring period corresponding to the PDCCH search space 3 is PDCCH monitoring period 5, the terminal device monitors the PDCCH in PDCCH monitoring period 3 and PDCCH monitoring period 5.
In still another possible implementation manner, the network device may further adjust the PDCCH monitoring period of the terminal device by adjusting the CORESET and the PDCCH search space of the terminal device. Specifically, the indication information received by the terminal device and sent by the network device is first indication information and third indication information, where the first indication information is used to indicate the adjusted target search space, and the third indication information is used to indicate the adjusted target control resource set. Correspondingly, the terminal device monitors the corresponding resource set in at least one monitoring period of the target search space corresponding to the target control resource set.
For example, the DL BWP currently activated by the terminal device is DL BWP1, and DL BWP1 has two CORESET, denoted CORESET1 and CORESET 2. The CORESET1 corresponds to a PDCCH search space 1, the PDCCH search space 1 corresponds to a PDCCH monitoring period 1, and the PDCCH monitoring period 1 is 2 slots. CORESET2 corresponds to two PDCCH search spaces, PDCCH search space 2 and PDCCH search space 3, respectively. The PDCCH search space 2 corresponds to 3 PDCCH monitoring periods, which are PDCCH monitoring period 2, PDCCH monitoring period 3, and PDCCH monitoring period 4, respectively. The PDCCH search space 3 corresponds to two PDCCH monitoring periods, namely a PDCCH monitoring period 5 and a PDCCH monitoring period 6. The terminal device currently monitors the PDCCH in PDCCH search space 1 monitoring period 1 corresponding to CORESET 1.
The network device may transmit first indication information indicating that the adjusted target search space is the PDCCH search space 3 and third indication information indicating that the adjusted target CORESET is the CORESET2 to the terminal device. When the terminal device receives the first indication information and the third indication information, the CORESET2 and the PDCCH search space 3 are activated, and the PDCCH is monitored in two PDCCH monitoring periods, namely PDCCH monitoring period 5 and PDCCH monitoring period 6, of the PDCCH search space 3 corresponding to the CORESET 2. In some embodiments, when the terminal device receives the first indication information and the third indication information, the terminal device may also not monitor the PDCCH in two PDCCH monitoring periods of the PDCCH search space 3 corresponding to the CORESET2 or in PDCCH monitoring periods of all the corresponding PDCCHs, or the terminal device monitors the PDCCH in a default monitoring period of the two PDCCH monitoring periods of the PDCCH search space 3 corresponding to the CORESET 2.
In yet another possible implementation manner, the network device may further adjust a CORESET and a PDCCH monitoring period of the terminal device. Specifically, the indication information received by the terminal device and sent by the network device is second indication information and third indication information, where the second indication information is used to indicate the adjusted target monitoring period, and the third indication information is used to indicate the adjusted target control resource set; correspondingly, the terminal device monitors the corresponding resource set in the target monitoring period corresponding to the target control resource set.
For example, the DL BWP currently activated by the terminal device is DL BWP1, and DL BWP1 has two CORESET, denoted CORESET1 and CORESET 2. Wherein, the CORESET1 corresponds to a PDCCH search space 1, and the PDCCH search space 1 corresponds to a PDCCH monitoring period 1. The CORESET2 corresponds to a PDCCH search space 2, and the PDCCH search space 2 corresponds to a PDCCH monitoring period 2 and a PDCCH monitoring period 3. The terminal device currently monitors the PDCCH in PDCCH search space 1 monitoring period 1 corresponding to CORESET 1.
The network device may send second indication information and third indication information to the terminal device, where the second indication information indicates that the adjusted target monitoring period is PDCCH monitoring period 3, and the third indication information indicates that the adjusted target CORESET is CORESET 2. When the terminal device receives the second indication information and the third indication information, activating the CORESET2 and the PDCCH monitoring period 3, and monitoring the PDCCH on the PDCCH monitoring period 3 corresponding to the CORESET 2. Optionally, if the PDCCH search spaces corresponding to the core set2 are 2 and 3, and PDCCH monitoring periods 3 are configured in both the PDCCH search spaces 2 and 3, when the terminal device receives the second indication information and the third indication information, the core set2 and the PDCCH monitoring period 3 are activated, and the PDCCH may be monitored in all PDCCH monitoring periods 3 corresponding to the core set2, or the PDCCH may not be monitored in the PDCCH monitoring period 3 corresponding to the core set2 or in all PDCCH monitoring periods, or the PDCCH may be monitored in the PDCCH monitoring period 3 of the default PDCCH search space (for example, search space 2) corresponding to the core set 2.
In still another possible implementation manner, the network device may further adjust the CORESET, the PDCCH search space, and the PDCCH monitoring period of the terminal device. Specifically, the indication information received by the terminal device and sent by the network device is first indication information, second indication information and third indication information, where the first indication information is used to indicate the adjusted target search space, the second indication information is used to indicate the adjusted target monitoring period, and the third indication information is used to indicate the adjusted target control resource set; correspondingly, the terminal device monitors the corresponding resource set in the target monitoring period of the target search space corresponding to the target control resource set.
For example, the DL BWP currently activated by the terminal device is DL BWP1, and DL BWP1 has two CORESET, denoted CORESET1 and CORESET 2. Wherein, the CORESET1 corresponds to a PDCCH search space 1, and the PDCCH search space 1 corresponds to a PDCCH monitoring period 1. The CORESET2 corresponds to a PDCCH search space 2, and the PDCCH search space 2 corresponds to a PDCCH monitoring period 2 and a PDCCH monitoring period 3. The terminal device currently monitors the PDCCH in PDCCH search space 1 monitoring period 1 corresponding to CORESET 1.
The network device may send, to the terminal device, first indication information indicating that the adjusted target search space is PDCCH search space 2, second indication information indicating that the adjusted target monitoring period is PDCCH monitoring period 3, and third indication information indicating that the adjusted target CORESET is CORESET 2. When the terminal device receives the first indication information, the second indication information and the third indication information, activating the CORESET2, the PDCCH search space 2 and the PDCCH monitoring period 3, and monitoring the PDCCH on the PDCCH monitoring period 3 of the PDCCH search space 2 corresponding to the CORESET 2.
It should be noted that, the default described in this embodiment may be predefined, may be indicated to the UE by the network, or may be obtained by negotiation interaction between the UE and the network.
In the resource set monitoring method provided by this embodiment, the network device adjusts at least one of the CORESET, the PDCCH search space, and the PDCCH monitoring period of the terminal device to dynamically adjust the monitoring period for the terminal device to monitor the PDCCH, so that the flexibility of dynamically adjusting the monitoring period is improved.
It should be noted that, when at least one of the CORESET, the search space, and the monitoring period changes, that is, when the network device adjusts at least one of the CORESET, the search space, and the monitoring period corresponding to the terminal device, the network device may only indicate information that the terminal device changes, or the network device may indicate information that the terminal device changes and information that the terminal device does not change. For example, when only the listening period changes in the CORESET, the search space, and the listening period, the network device may indicate only the changed listening period, and at this time, the terminal device defaults to CORESET, the search space, and the BWP without changing. Alternatively, the network device may indicate the changed listening period of the terminal device and at least one of currently unchanged CORESET, search space, BWP.
In the above embodiment, the first indication information is used to indicate the adjusted target search space, and specifically, the first indication information indicates the adjusted target search space by carrying identification information of the target search space. In this embodiment, the first indication information may also indicate the target search space in other manners.
One possible way is that the first indication information indicates the target search space in the at least one search space corresponding to the currently activated working bandwidth in a bitmap (bitmap) manner.
Optionally, the length of the bitmap is fixed. Specifically, the length of the bitmap is related to at least one of the following: the number of search spaces configured for the terminal device by the network device, the number of maximum search spaces configured or supported by the network device, the number of maximum search spaces supported by the terminal device, the number of specified maximum search spaces, the number of maximum search spaces supported by a BWP, and the number of maximum search spaces supported by a CORESET. For example, the currently active operating bandwidth of the terminal device is DL BWP1, and the maximum number of PDCCH search spaces that the network device can configure to the terminal device is 10 on this DL BWP1, then this bitmap can use a fixed 10-bit or 2-byte bit string to identify the target search space. Taking fixed 10 bits as an example, each of the 10 bits corresponds to one PDCCH search space, for example, the 10 PDCCH search spaces are identified as 1-10, the 1 st bit of the 10 bits in a left-to-right sequence corresponds to PDCCH search space 1, the 2 nd bit of the sequence corresponds to PDCCH search space 2, and so on, the 10 th bit of the sequence corresponds to PDCCH search space 10. In other embodiments, the 10 bits may also sequentially identify PDCCH search spaces in order from right to left, for example, the 1 st bit of the 10 bits in order from right to left corresponds to PDCCH search space 1.
In this embodiment, each of the 10 bits may be 1 or 0, and this embodiment uses 0 to represent inactive and 1 to represent active. In other embodiments, 0 may be used to indicate active and 1 may be used to indicate inactive.
For example, if the bit string of 10 bits is 0000000001, it indicates that PDCCH search space 1 is active and other PDCCH search spaces are inactive. Further, the network device may adjust the activated PDCCH search space to PDCCH search space 2 by sending bitmap 0000000010 to the terminal device.
In other embodiments, 4 bits or 1byte may also be used to identify an active search space. For example, the network device may send bitmap0000 to the terminal device to represent that the activated PDCCH search space is PDCCH search space 1, the network device may send bitmap0001 to the terminal device to represent that the activated PDCCH search space is PDCCH search space 2, the network device may send bitmap0010 to the terminal device to represent that the activated PDCCH search space is PDCCH search space 3, and so on.
In addition, the length of the bitmap may also be variable. Specifically, the length of the bitmap is related to the number of search spaces associated with each control resource set configured for the terminal device by the network device.
For example, the DL BWP currently activated by the terminal device is DL BWP1, DL BWP1 is configured with two CORESET, which are denoted as CORESET1 and CORESET2, and the number of PDCCH search spaces associated with CORESET1 may be different from the number of PDCCH search spaces associated with CORESET 2. For example, CORESET1 is associated with 4 PDCCH search spaces and CORESET2 is associated with 5 PDCCH search spaces. If the currently active CORESET is CORESET1, the bitmap is 4 bits in length. If the currently active CORESET is CORESET2, the bitmap is 5 bits in length. In some embodiments, the length of the bitmap may also be determined in bytes. For example, if the number of PDCCH search spaces associated with the currently activated CORESET is less than or equal to 8, a bitmap with a length of 1byte is used to identify the target search space, and the specific identification method is as described above and is not described herein again. In other embodiments, another bitmap indication mode may also be adopted. For example, for CORESET1, since CORESET1 is associated with 4 PDCCH search spaces, the activated PDCCH search spaces may be indicated in a 2-bit or 1-byte manner. For example, the network device may send bitmap00 to the terminal device, the PDCCH search space representing activation is PDCCH search space 1, the network device may send bitmap 01 to the terminal device, the PDCCH search space representing activation is PDCCH search space 2, the network device may send bitmap 10 to the terminal device, the PDCCH search space representing activation is PDCCH search space 3, and so on.
Another possible way is that the first indication information indicates, in a pattern (pattern) manner, the target search space in the at least one search space corresponding to the currently activated operating bandwidth. Optionally, the length of the pattern is fixed, or variable.
Specifically, the first indication information includes an activation order of at least one search space corresponding to a currently activated operating bandwidth or an activation order of the at least one search space within a period of time. For example, the currently activated BWP corresponds to 4 PDCCH search spaces, and the identification information of the 4 PDCCH search spaces is 1,2,3, and 4, respectively. Each of the 4 PDCCH search spaces corresponds to one PDCCH monitoring period, for example, the PDCCH monitoring periods corresponding to each PDCCH search space are different. The first indication information includes an activation order of the 4 PDCCH search spaces or an activation order of the 4 PDCCH search spaces over a period of time. For example, the activation order of the 4 PDCCH search spaces is 4, 2,3,1, 4, 3,1, and the terminal device activates the 4 PDCCH search spaces according to the activation order of the 4 PDCCH search spaces after receiving the first indication information, for example, the PDCCH search space 4, the PDCCH search space 2, the PDCCH search space 3, the PDCCH search space 1, the PDCCH search space 4, the PDCCH search space 3, and the PDCCH search space 1 are sequentially activated. The target search space indicated by the first indication information is specifically a currently activated PDCCH search space in the 4 PDCCH search spaces.
In this embodiment, the network device may further configure at least one of an activation duration, an activation time, an activation number of times of each PDCCH search space in the 4 PDCCH search spaces and a period corresponding to an activation order of the 4 PDCCH search spaces. In a possible manner, the first indication information may include, in addition to the activation order of the 4 PDCCH search spaces, at least one of an activation duration, an activation time, an activation number of each of the 4 PDCCH search spaces and a period corresponding to the activation order of the 4 PDCCH search spaces. In another possible manner, the RRC configuration information may further include at least one of an activation duration, an activation time, an activation number of times of activation of each PDCCH search space in the 4 PDCCH search spaces and a period corresponding to an activation order of the 4 PDCCH search spaces. In another possible manner, the network device sends other information except the first indication information and the RRC configuration information to the terminal device, and the other information (such as one of dedicated RRC message, MAC CE, DCI, WUS, etc.) carries at least one of the activation duration, the activation time, the activation times of each of the 4 PDCCH search spaces and a period corresponding to the activation order of the 4 PDCCH search spaces.
Correspondingly, when the terminal device activates the 4 PDCCH search spaces according to the activation order of the 4 PDCCH search spaces, the 4 PDCCH search spaces may be specifically activated according to the activation order of the 4 PDCCH search spaces, and at least one of the activation duration, the activation time, the activation times of each PDCCH search space in the 4 PDCCH search spaces and a period corresponding to the activation order of the 4 PDCCH search spaces.
Optionally, the network device may further indicate the enabled time of the pattern corresponding to the first indication information of the terminal device, that is, the time when the pattern starts to be used. Specifically, the network device may instruct the terminal device to: the receiving time of the first indication information and/or the working bandwidth switching information (i.e. the information instructing the end device to switch to BWP 2) received by the end device is the time when pattern is enabled. Or, the network device instructs the terminal device to: the preset time after the terminal device receives the first indication information and/or the preset time after the terminal device receives the working bandwidth switching information is the time for enabling the pattern. The preset time is greater than or equal to 0. Optionally, the information used by the network device to indicate the pattern enable time may also be indicated by other special information. In addition, when the first indication information indicates the adjusted target search space through bitmap, the network device may also use a similar manner, that is, indicate the use time of information corresponding to bitmap.
For example, the network device configures an activation duration for each of the 4 PDCCH search spaces, and the activation duration for each PDCCH search space may be implemented by activating a timer. The activation duration of each PDCCH search space may be the same or different. That is, the duration of the activation timer for each PDCCH search space may be the same or different. For example, when the network device indicates that a certain BWP is active, the terminal device may activate the PDCCH search spaces according to the activation order of the PDCCH search spaces corresponding to the BWP and the activation duration of each PDCCH search space. For example, the terminal device activates the PDCCH search space 4 first, and activates the PDCCH search space 2 after an activation timer corresponding to the PDCCH search space 4 expires. After the activation timer corresponding to the PDCCH search space 2 expires, the PDCCH search space 3 is activated, and so on.
For another example, the network device configures a cycle of the activation order of the 4 PDCCH search spaces to be 40ms, the activation order of the 4 PDCCH search spaces is 4, 2,3,1, 4, 3,1 in any 40ms, and the activation order of the 4 PDCCH search spaces may be 4, 2,3,1, 4, 3,1 in the next 40ms, or another order different from the order. The terminal device activates the plurality of PDCCH search spaces according to the activation order of the 4 PDCCH search spaces and the activation duration of each PDCCH search space within each 40 ms.
For another example, the network device configures a cycle of the activation order of the 4 PDCCH search spaces to be 40ms, the activation order of the 4 PDCCH search spaces is 4, 2,3,1, 4, 3,1 in any 40ms, and the activation order of the 4 PDCCH search spaces may be 4, 2,3,1, 4, 3,1 in the next 40ms, or another order different from the order. The terminal device activates the plurality of PDCCH search spaces according to the activation order of the 4 PDCCH search spaces within 40ms and the 1 or 0 identifier given at each time point within 40 ms. For example, within 40ms, 1ms, 5ms, 10ms, and 30ms are denoted by 1, which means that the PDCCH search space activated from 1ms is PDCCH search space 4, the PDCCH search space activated from 5ms is PDCCH search space 2, the PDCCH search space activated from 10ms is PDCCH search space 3, and the PDCCH search space activated from 30ms is PDCCH search space 1. And so on.
For another example, the network device may also configure the activation time and/or the activation times of each of the 4 PDCCH search spaces. The activation time of each PDCCH search space may specifically refer to a starting time or each time when each PDCCH search space is activated. The number of activations of each PDCCH search space may be the total number of activations of the PDCCH search space by the terminal device or the total number of activations of the PDCCH search space within one 40 ms. Each PDCCH search space may be activated continuously or discontinuously.
In the resource collection monitoring method provided by this embodiment, the first indication information indicates the target search space in the at least one search space corresponding to the currently activated working bandwidth in a bitmap manner or a pattern manner, so that flexibility of indicating the target search space by the first indication information is improved.
In the above embodiment, the second indication information is used to indicate the adjusted target listening period. Specifically, the second indication information indicates the adjusted target listening period by carrying identification information of the target listening period. In this embodiment, the second indication information may also indicate the target listening period in other manners.
One possible way is that the second indication information indicates the target listening period in at least one listening period corresponding to the currently activated working bandwidth in a bitmap way.
Optionally, the length of the bitmap is fixed or variable. Specifically, the length of the bitmap is related to at least one of the following: the number of the monitoring periods configured for the terminal device by the network device, the number of the maximum monitoring periods configured or supported by the network device, the number of the maximum monitoring periods supported by the terminal device, the number of the specified maximum monitoring periods, the number of the maximum monitoring periods supported by a BWP, the number of the maximum monitoring periods supported by a CORESET, the number of the maximum monitoring periods supported by a search space, and the number of the monitoring periods corresponding to the currently activated search space or the target search space are related. For example, the terminal device currently activates PDCCH search space 2, where PDCCH search space 2 corresponds to 3 PDCCH monitoring periods, and the identification information of the 3 PDCCH monitoring periods is 1,2, and 3, respectively. The length of the bit map is 3 bits, and the 3 bits may be sorted from small to large according to the identification information of the 3 PDCCH monitoring periods, for example, the rightmost bit of the bit map corresponds to the PDCCH monitoring period with the smallest identification information. Assume that the terminal device currently monitors the PDCCH in PDCCH monitoring period 1. In order to adjust the PDCCH monitoring period of the terminal device, the second indication information indicates the adjusted target monitoring period in the 3 PDCCH search spaces in a bitmap manner. For example, the bit map is 010, the terminal device determines that the activated PDCCH search space is unchanged, the PDCCH monitoring period is changed to PDCCH monitoring period 2, and correspondingly, the terminal device adjusts to the currently activated PDCCH search space, that is, PDCCH monitoring period 2 corresponding to PDCCH search space 2 to monitor the PDCCH.
For another example, the terminal device currently activates the PDCCH search space 2, and the network device may adjust the PDCCH search space currently activated by the terminal device to the target search space through the first indication information, for example, the target search space is the PDCCH search space 1, the PDCCH search space 1 corresponds to 4 PDCCH monitoring periods, the identification information of the 4 PDCCH monitoring periods is 1,2,3, and 4, respectively, and the bit map length corresponding to the second indication information is 4 bits or 1 byte. For example, if the bit map is 1000, the terminal device adjusts to the PDCCH monitoring period 4 corresponding to the PDCCH search space 1 to monitor the PDCCH.
Or, another bitmap indication manner may also be adopted, for example, the network device may send bitmap0000 to the terminal device, where the activated PDCCH monitoring period is PDCCH monitoring period 1, the network device may send bitmap0001 to the terminal device, where the activated PDCCH monitoring period is PDCCH monitoring period 2, the network device may send bitmap0010 to the terminal device, and the activated PDCCH monitoring period is PDCCH monitoring period 3, and so on.
Alternatively, in some other embodiments, another bitmap indication mode may be adopted. For example, the PDCCH search space 1 is associated with 4 PDCCH monitoring periods, and the bit map length corresponding to the second indication information is 2 bits. For example, if the bit map is 01, the terminal device adjusts to the PDCCH monitoring period 2 corresponding to the PDCCH search space 1 to monitor the PDCCH, and if the bit map is 11, the terminal device adjusts to the PDCCH monitoring period 4 corresponding to the PDCCH search space 1 to monitor the PDCCH.
Another possible manner is that the second indication information indicates, in a pattern (pattern) manner, the target listening period in at least one listening period corresponding to the currently activated working bandwidth. Optionally, the length of the pattern is fixed, or variable.
Specifically, the second indication information includes an activation order of at least one listening period corresponding to the currently activated search space or the target search space or an activation order of the one listening period within a period of time. For example, the currently activated search space or the adjusted target search space corresponds to 3 PDCCH monitoring periods, and the identification information of the 3 PDCCH monitoring periods is 1,2, and 3, respectively. The PDCCH monitoring period 1 is 2 time slots, the PDCCH monitoring period 2 is 4 time slots, and the PDCCH monitoring period 3 is 8 time slots. The second indication information includes an activation order of the 3 PDCCH monitoring periods or an activation order of the 3 PDCCH monitoring periods within a period of time. For example, the activation sequence of the 3 PDCCH monitoring periods is 3,1,2,2,3,1, and the terminal device activates the 3 PDCCH monitoring periods according to the activation sequence of the 3 PDCCH monitoring periods after receiving the second indication information, for example, the PDCCH monitoring period 3, the PDCCH monitoring period 1, the PDCCH monitoring period 2, the PDCCH monitoring period 3, and the PDCCH monitoring period 1 are activated in sequence. The target monitoring period indicated by the second indication information is specifically a currently activated PDCCH monitoring period in the 3 PDCCH monitoring periods, or an activation sequence of the PDCCH monitoring periods within a period of time.
In this embodiment, the network device may further configure at least one of an activation duration, an activation time, an activation number of each PDCCH monitoring period in the 3 PDCCH monitoring periods, and a period corresponding to an activation order of the 3 PDCCH monitoring periods. The configuration information for configuring at least one of the activation duration, the activation time, the activation times of each PDCCH monitoring period in the 3 PDCCH monitoring periods and the period corresponding to the activation sequence of the 3 PDCCH monitoring periods may be carried in the second indication information, or carried in the RRC configuration information as described above, or carried in other information except the second indication information and the RRC configuration information. The activation time of each PDCCH monitoring period may be specifically a starting time or each time when each PDCCH monitoring period is activated.
Correspondingly, when the terminal device activates the 3 PDCCH monitoring periods according to the activation sequence of the 3 PDCCH monitoring periods, the 3 PDCCH monitoring periods may be specifically activated according to the activation sequence of the 3 PDCCH monitoring periods and at least one of the activation duration, the activation time, the activation times of each PDCCH monitoring period in the 3 PDCCH monitoring periods and a period corresponding to the activation sequence of the 3 PDCCH monitoring periods.
For example, the network device configures the activation sequence of the 3 PDCCH monitoring periods to have a period of 40ms, and within any 40ms, the activation sequence of the 3 PDCCH monitoring periods is 3,1, 2. In the next 40ms, the activation order of the 3 PDCCH monitoring periods is 2,3, 1. And the number of activation times of each PDCCH monitoring period in the 3 PDCCH monitoring periods is 4 within one 40 ms. That is, each PDCCH monitoring period may be continuously activated 4 times within one 40ms, as shown in fig. 4, or intermittently activated 4 times per PDCCH monitoring period.
For another example, the network device configures a period of an activation sequence of the 3 PDCCH monitoring periods to be 40ms, the activation sequence of the 3 PDCCH monitoring periods is 3,1,2,2,3,1 in any 40ms, and the activation sequence of the 3 PDCCH monitoring periods may be 3,1,2,2,3,1 in the next 40ms, or another sequence different from the sequence. The terminal device activates the plurality of PDCCH monitoring periods according to the activation sequence of the 3 PDCCH monitoring periods within 40ms and the 1 or 0 identifier given at each time point within 40 ms. For example, within 40ms, 1ms, 5ms, 10ms, 15ms, 20ms, and 30ms are labeled as 1, which means that the PDCCH monitoring period activated from 1ms is PDCCH monitoring period 3, the PDCCH monitoring period activated from 5ms is PDCCH monitoring period 1, the PDCCH monitoring period activated from 10ms is PDCCH monitoring period 2, and the PDCCH monitoring period activated from 30ms is PDCCH monitoring period 2. And so on. Optionally, the network device may further indicate the enabled time of the pattern corresponding to the second indication information of the terminal device, that is, the time when the pattern starts to be used. Specifically, the network device may instruct the terminal device to: the receiving time of the second indication information and/or the working bandwidth switching information (i.e. the information instructing the end device to switch to BWP 2) received by the end device is the time when pattern is enabled. Or, the network device instructs the terminal device to: the preset time after the terminal device receives the second indication information and/or the preset time after the terminal device receives the working bandwidth switching information is the time for enabling the pattern. The preset time is greater than or equal to 0. Optionally, the information used by the network device to indicate the pattern enable time may also be indicated by other special information. In addition, when the second indication information indicates the adjusted target listening period through the bitmap, the network device may also use a similar manner, that is, indicate the use time of the information corresponding to the bitmap.
In the resource set monitoring method provided by this embodiment, the second indication information indicates the target monitoring period in at least one monitoring period corresponding to the currently activated working bandwidth in a bitmap manner or a pattern manner, so that flexibility of indicating the target monitoring period by the second indication information is improved.
In the above embodiment, the third indication information is used to indicate the adjusted target CORESET. Specifically, the third indication information indicates the adjusted target CORESET by carrying the identification information of the target CORESET. In this embodiment, the third indication information may also indicate the target CORESET in other manners.
One possible way is that the third indication information indicates the target control resource set in the at least one control resource set corresponding to the currently activated working bandwidth in a bitmap manner.
Optionally, the length of the bitmap is fixed or variable. Specifically, the length of the bitmap is related to at least one of the following: the number of CORESETs configured for the terminal device by the network device, the number of the maximum CORESETs configured or supported by the network device, the number of the maximum CORESETs supported by the terminal device, the number of the specified maximum CORESET, the number of the maximum CORESET supported by one BWP, and the number of the control resource sets corresponding to the currently activated working bandwidth are related. The method for indicating the target control resource set by the third indication information through a bitmap (bitmap) is similar to the method for indicating the target listening period by the second indication information through a bitmap or indicating the target search space by the first indication information through a bitmap in the above embodiment, and is not repeated here.
For example, the network device configures 4 CORESET to the terminal device, the identification information of the 4 CORESET is 1,2,3,4 in sequence, and the network device may identify the activated CORESET by using 4 bits or 1 byte. For example, the network device may represent an active CORESET by sending a bitmap0001 to the terminal device, CORESET 1by sending a bitmap0010 to the terminal device, CORESET2 by sending a bitmap 0100 to the terminal device, CORESET3 by sending an active CORESET, and so on.
Alternatively, another indication manner of bitmap may be adopted, for example, the network device may send bitmap0000 to the terminal device to represent that the activated CORESET is CORESET1, the network device may send bitmap0001 to the terminal device to represent that the activated CORESET is CORESET2, the network device may send bitmap0010 to the terminal device to represent that the activated CORESET is CORESET3, and so on.
Alternatively, in some other embodiments, another bitmap indication mode may be adopted. For example, since the network device configures 4 CORESET to the terminal device, the activated CORESET may be indicated in a 2-bit or 1-byte manner. For example, the network device may send bitmap00 to the terminal device to represent that the activated CORESET is CORESET1, the network device may send bitmap 01 to the terminal device to represent that the activated CORESET is CORESET2, the network device may send bitmap 10 to the terminal device to represent that the activated CORESET is CORESET3, and the network device may send bitmap 11 to the terminal device to represent that the activated CORESET is CORESET 4.
Another possible way is that the third indication information indicates, in a pattern (pattern) manner, the target control resource set in the at least one control resource set corresponding to the currently activated working bandwidth. Optionally, the length of the pattern is fixed, or variable.
Specifically, the third indication information includes an activation order of at least one control resource set corresponding to the currently activated working bandwidth or an activation order of the at least one control resource set within a period of time. The target control resource set indicated by the third indication information is specifically a currently activated control resource set in the at least one control resource set, or an activation order of the control resource sets within a period of time. Specifically, the method for indicating the target control resource set by the third indication information in the pattern manner is similar to the method for indicating the target listening period by the second indication information in the pattern manner or indicating the target search space by the first indication information in the pattern manner in the above embodiment, and details are not repeated here.
For example, the currently activated BWP corresponds to 4 CORESET, and the third indication information includes the activation sequence of the 4 CORESET or the activation sequence of the 4 CORESET within a period of time. For example, the activation sequence of the 4 CORESET is 4, 2,3,1, 4, 3,1, the terminal device activates the 4 CORESET according to the activation sequence of the 4 CORESET after receiving the third indication information. For example, CORESET4, CORESET2, CORESET3, CORESET1, CORESET4, CORESET3, CORESET1 are activated in sequence.
In addition, the network device may further configure at least one of a period corresponding to an activation duration, an activation time, an activation number of times of each of the at least one control resource set, and an activation order of the at least one control resource set. When the terminal device activates the at least one control resource set according to the activation order of the at least one control resource set, the terminal device may specifically activate the at least one control resource set according to at least one of the activation order activation of the at least one control resource set, and a period corresponding to the activation duration, the activation time, the activation frequency, and the activation order of the at least one control resource set. The activation time of each core set may specifically be a starting time or each time when each core set is activated.
For example, the network device configures an activation duration for each of the 4 core sets, and the activation duration for each core set may be implemented by activating a timer. The activation time of each CORESET may be the same or different. For example, when the network device indicates that a certain CORESET is activated, the terminal device may activate the CORESETs according to the activation sequence of the CORESETs corresponding to the BWP and the activation duration of each CORESET. For example, the terminal device activates CORESET4 first, activates CORESET2 after the activation timer corresponding to CORESET4 expires, activates CORESET3 after the activation timer corresponding to CORESET2 expires, and so on.
For another example, the network device configures the activation sequence of the 4 CORESETs to have a period of 40ms, the activation sequence of the 4 CORESETs is 4, 2,3,1, 4, 3,1 in any 40ms, and the activation sequence of the 4 CORESETs may be 4, 2,3,1, 4, 3,1 in the next 40ms, or another sequence different from the sequence. The terminal equipment activates the CORESETs according to the activation sequence of the 4 CORESETs in each 40ms and the activation duration of each CORESET.
For another example, the network device configures the activation sequence of the 4 CORESETs to have a period of 40ms, the activation sequence of the 4 CORESETs is 4, 2,3,1, 4, 3,1 in any 40ms, and the activation sequence of the 4 CORESETs may be 4, 2,3,1, 4, 3,1 in the next 40ms, or another sequence different from the sequence. The terminal equipment activates the CORESETs according to the activation sequence of the 4 CORESETs within 40ms and the identification of 1 or 0 given at each time point within 40 ms. For example, within 40ms, 1ms, 5ms, 10ms, and 30ms are labeled as 1, which means that CORESET activated from 1ms is CORESET4, CORESET activated from 5ms is CORESET2, CORESET activated from 10ms is CORESET3, and CORESET activated from 30ms is CORESET 1. And so on.
Optionally, the network device may further indicate the enabled time of the pattern corresponding to the third indication information, that is, the time when the pattern starts to be used by the terminal device. Specifically, the network device may instruct the terminal device to: the receiving time of the third indication information and/or the working bandwidth switching information (i.e. the information instructing the end-point device to switch to BWP 2) received by the end-point device is the time when pattern is enabled. Or, the network device instructs the terminal device to: the preset time after the terminal device receives the third indication information and/or the preset time after the terminal device receives the working bandwidth switching information is the time for enabling the pattern. The preset time is greater than or equal to 0. Optionally, the information indicating the pattern enable time by the network device may also be indicated by other special information. In addition, when the third indication information indicates the adjusted target control resource set through the bitmap, the network device may also use a similar manner, i.e., indicate the usage time of the information corresponding to the bitmap.
In the resource set monitoring method provided in this embodiment, the third indication information indicates the target control resource set in the at least one control resource set corresponding to the currently activated working bandwidth in a bitmap manner or a pattern manner, so that flexibility of indicating the target control resource set by the third indication information is improved.
The above embodiments describe that the network device may adjust at least one of the currently activated CORESET, the search space, and the listening period of the terminal device. In this embodiment, the network device may also adjust the BWP currently activated by the terminal device. For example, after the terminal device receives the configuration information sent by the network device, as shown in fig. 5, the method further includes the following steps:
step S501, receiving the working bandwidth switching information sent by the network equipment.
For example, the network device configures at least one DL BWP for the terminal device through the RRC configuration information, and at different time instants, the network device may instruct the terminal device to activate different DL BWPs.
In this embodiment, the terminal device may implement the switching of DL BWP in several ways:
one way is to implement handover of DL BWP based on PDCCH.
Another way is to implement the handover of DL BWP based on RRC configuration information.
Yet another way is to implement the handover of DL BWP based on timer timeout.
Yet another way is to implement handover of DL BWP based on random access initialization.
For example, the currently activated DL BWP of the terminal device is DL BWP1, and the network device adjusts the currently activated DL BWP of the terminal device to DL BWP2 by sending the working bandwidth switching information to the terminal device. Specifically, the working bandwidth switching information may be carried in PDCCH or RRC configuration information.
And step S502, switching to the target working bandwidth according to the working bandwidth switching information.
The terminal device receives the operating bandwidth switching information and switches to the target operating bandwidth, for example, DL BWP 2.
Step S503, determining at least one of an initially activated control resource set, an initially activated search space, and an initially activated listening period corresponding to the target working bandwidth.
Since the control resource sets, search spaces, or listening periods corresponding to different DL BWPs are different, when the terminal device switches to the DL BWP2, at least one of the initially activated control resource set, the initially activated search space, and the initially activated listening period corresponding to the DL BWP2 needs to be determined.
Specifically, the terminal device may determine at least one of an initially activated control resource set, an initially activated search space, and an initially activated listening period corresponding to the DL BWP2 through several possible implementations as follows.
One possible implementation is: the RRC configuration information sent by the network device to the terminal device further includes: the network device configures at least one of an initially activated control resource set, an initially activated search space and an initially activated listening period corresponding to each working bandwidth in at least one working bandwidth for the terminal device. Accordingly, the terminal device determines at least one of an initially activated control resource set, an initially activated search space, and an initially activated listening period corresponding to the DL BWP2 according to the RRC configuration information.
Another possible implementation is: the terminal device receives at least one of fourth indication information, fifth indication information and sixth indication information sent by the network device, wherein the fourth indication information is used for indicating an activated search space, the fifth indication information is used for indicating an activated monitoring period, and the sixth indication information is used for indicating an activated control resource set; the terminal device determines that the activated search space indicated by the fourth indication information is the initially activated search space corresponding to the target working bandwidth, the activated monitoring period indicated by the fifth indication information is the initially activated monitoring period corresponding to the target working bandwidth, and the activated control resource set indicated by the sixth indication information is the initially activated control resource set corresponding to the target working bandwidth.
It should be noted that the network device may further indicate an enabling time, a usage duration and/or a usage deadline of information corresponding to at least one of the fourth indication information, the fifth indication information and the sixth indication information, for example, the network device may indicate an enabling time, a usage duration and/or a usage deadline of an activated search space indicated by the fourth indication information (i.e., from when the search space indicated by the fourth indication information is activated and/or the activated search space is used and/or the usage deadline), an enabling time, a usage duration and/or a usage deadline of an activated listening period indicated by the fifth indication information (i.e., from when the listening period indicated by the fifth indication information is activated and/or, a duration that the active listening period is used, and/or a usage deadline) and at least one of an activation time, a usage duration, and/or a usage deadline of the active control resource set indicated by the sixth indication information (i.e., from when the control resource set indicated by the sixth indication information is activated, and/or a duration that the active control resource set is used, and/or a usage deadline).
In one possible approach, the fourth indication information may include an activation time, a usage duration and/or a usage deadline of the activated search space, the fifth indication information may include an activation time, a usage duration and/or a usage deadline of the activated listening period, and the sixth indication information may include an activation time, a usage duration and/or a usage deadline of the activated control resource set.
In another possible manner, the network device may further indicate, by other dedicated information, an enabling time, a usage duration, and/or a usage deadline of information corresponding to at least one of the fourth indication information, the fifth indication information, and the sixth indication information.
Specifically, when the fourth indication information indicates the activated search space through bitmap or pattern, the fourth indication information may include an enabling time, a usage duration and/or a usage deadline of information corresponding to the bitmap or pattern, or the network device indicates the enabling time, the usage duration and/or the usage deadline of information corresponding to the bitmap or pattern through other special information.
Similarly, when the fifth indication information indicates the activated listening period through bitmap or pattern, the fifth indication information may include the enabling time, the use duration and/or the use deadline of the information corresponding to bitmap or pattern, or the network device indicates the enabling time, the use duration and/or the use deadline of the information corresponding to bitmap or pattern through other special information.
Similarly, when the sixth indication information indicates the activated control resource set through bitmap or pattern, the sixth indication information may include the enabling time, the usage duration and/or the usage deadline of the information corresponding to bitmap or pattern, or the network device indicates the enabling time, the usage duration and/or the usage deadline of the information corresponding to bitmap or pattern through other special information.
The following is a schematic description by taking an example that the terminal device determines an initially activated search space corresponding to a target operating bandwidth. Specifically, the network device configures DL BWP1 and DL BWP2 to the terminal device through RRC configuration information, and the network device further configures at least one PDCCH search space to DL BWP1 and DL BWP2, where at least one PDCCH search space corresponding to DL BWP1 includes at least one initially activated PDCCH search space, and at least one PDCCH search space corresponding to DL BWP2 includes at least one initially activated PDCCH search space. After the terminal device switches to DL BWP2, if the terminal device does not receive other indication information from the network device to indicate which PDCCH search space the terminal device should use on the DL BWP2 as the initially activated PDCCH search space, the terminal device determines the initially activated PDCCH search space corresponding to DL BWP2 configured in the RRC configuration information as the PDCCH search space initially activated by the terminal device on the DL BWP 2.
After or before or when the terminal device switches to DL BWP2, if the terminal device receives other indication information sent by the network device for indicating which PDCCH search space the terminal device should use on the DL BWP2 as the initially activated PDCCH search space, the terminal device determines the PDCCH search space the terminal device initially activated on the DL BWP2 according to the other indication information. The other indication information may specifically be fourth indication information, where the fourth indication information is used to indicate an activated search space, and the terminal device determines that the activated search space indicated by the fourth indication information is a PDCCH search space initially activated by the terminal device on the DL BWP 2. Optionally, the fourth indication information indicates the activated search space in a bitmap manner or a pattern manner, and a specific indication manner is similar to the indication manner in which the first indication information indicates the target search space in the bitmap manner or the pattern manner, which is described in the foregoing embodiment, and is not described herein again. In addition, the operating bandwidth switching information as described above may further include the fourth indication information, that is, the network device indicates the terminal device to switch to the target operating bandwidth and also indicates the PDCCH search space initially activated on the target operating bandwidth. Or, the fourth indication information and the working bandwidth switching information are carried in PDCCH or RRC configuration information together. For example, the PDCCH received by the terminal device and carrying the operating bandwidth switching information also carries the fourth indication information, and the fourth indication information indicates an activated PDCCH search space in a bit map manner, then the terminal device determines the activated PDCCH search space according to the indication of the bit map, and uses the activated PDCCH search space as an initially activated PDCCH search space on the DL BWP2, and further monitors the PDCCH on the initially activated PDCCH search space.
For example, the network device configures DL BWP1 and DL BWP2 to the terminal device through RRC configuration information, currently active is DL BWP1, and DL BWP1 is configured with 2 PDCCH search spaces, where identification information of the 2 PDCCH search spaces is 1 and 2, respectively. The network device indicates, in a bitmap manner, that a currently activated PDCCH search space on DL BWP1 is PDCCH search space 2, and a PDCCH monitoring period corresponding to PDCCH search space 2 is 4 slots. The terminal device monitors the PDCCH on the PDCCH BWP1 on the PDCCH search space with PDCCH monitoring period of 4 slots, as shown at 60 in fig. 6.
DL BWP2 is configured with 3 PDCCH search spaces, where the identification information of the 3 PDCCH search spaces is 1,2, and 3 respectively, and the PDCCH monitoring periods corresponding to the 3 PDCCH search spaces are 2 slots, 4 slots, and 8 slots respectively. PDCCH search space 3, which is a PDCCH search space corresponding to a PDCCH monitoring period of 8 slots, is an initially activated PDCCH search space on DL BWP 2. As shown in fig. 6, at time t1, the terminal device receives information carried by a PDCCH sent by the network device, where the information carried by the PDCCH includes not only the operating bandwidth switching information for instructing the terminal device to switch to DL BWP2, but also fourth indication information indicating an active search space in a bitmap manner, for example, the bitmap is 001, and a plurality of bits in the bitmap are arranged in an order from small to large of search space identification information, that is, the rightmost bit of the bitmap corresponds to the PDCCH search space with the smallest identification information. Accordingly, the terminal device switches to DL BWP2 according to the operating bandwidth switching information and determines that the initially activated search space on DL BWP2 is PDCCH search space 1, i.e. a PDCCH search space with a PDCCH monitoring period of 2 slots. Further, the terminal device monitors the PDCCH on the PDCCH search space with a PDCCH monitoring period of 2 slots on DL BWP 2. In other embodiments, the fourth indication information is not limited to be carried in the PDCCH, and may also be carried in a Wake-up Signal (WUS) or a Medium Access Control (Medium Access Control) Control unit (Control Element, CE).
Further, at time t2, the terminal device receives first indication information sent by the network device, for example, the first indication information indicates the adjusted target search space by means of a bit map, the bit map is, for example, 110, then the terminal device determines that the adjusted target search space is PDCCH search space 3 and PDCCH search space 2, and then the terminal device switches to the PDCCH search space with PDCCH monitoring period of 8 slots and 4 slots on DL BWP2 to monitor the PDCCH after time t 2. In this embodiment, the device for carrying the first indication information may be a WUS, a MAC CE, or a PDCCH.
It can be understood that when WUS is used to adjust the activated PDCCH search space, the RRC configuration information as described above may further include: discontinuous Reception (DRX) configuration parameters and WUS configuration parameters. Wherein, the DRX configuration parameters include: DRX cycle (DRX cycle), DRX on state timer (DRX-onDurationTimer), and the like. The WUS configuration parameters may include: a wake-up signal timing (WUS event) period (which is an integer multiple of a DRX cycle) and a time offset wustimeooffset from the start of a DRX on state (DRX on duration, i.e., a state of constantly monitoring the PDCCH within one DRX cycle) following the WUS event start time.
It can be understood that when the activated PDCCH search spaces are indicated in a pattern, only one activated PDCCH search space can be indicated at each time. When the activated PDCCH search spaces are indicated in a bitmap manner, at least one activated PDCCH search space may be indicated at each time.
In addition, in the 5G NR system, the terminal device also supports a Carrier Aggregation (CA) technique. The network equipment configures a plurality of service cells for the terminal equipment, and the terminal equipment can simultaneously transmit and receive data in the plurality of service cells, so that the data transmission rate is improved. It can be understood that, in a CA scenario, for each serving cell of the terminal device, the terminal device may all adopt the method described in this embodiment to implement dynamic adjustment of a PDCCH monitoring period on each serving cell.
The following is a schematic description by taking an example that the terminal device determines an initially activated listening period corresponding to a target operating bandwidth. Specifically, the network device configures at least one DL BWP, for example, DL BWP1 and DL BWP2, to the terminal device through RRC configuration information. For each DL BWP in the at least one DL BWP, at least one PDCCH search space is configured, where one PDCCH search space corresponds to at least one PDCCH monitoring period, and each PDCCH monitoring period configures corresponding identification information. For each DL BWP, at least one PDCCH search space configured for the DL BWP includes at least one initially activated PDCCH search space, and/or at least one PDCCH monitoring period corresponding to the at least one PDCCH search space configured for the DL BWP includes at least one initially activated PDCCH monitoring period. After the terminal device switches to DL BWP2, if the terminal device does not receive other indication information from the network device to indicate which PDCCH search space the terminal device should use as the initially activated PDCCH search space on DL BWP2 and/or which PDCCH monitoring period should use as the initially activated PDCCH monitoring period, the terminal device determines that the initially activated PDCCH search space corresponding to DL BWP2 configured in the RRC configuration information is the PDCCH search space initially activated by the terminal device on DL BWP2, and/or determines that the initially activated PDCCH monitoring period corresponding to DL BWP2 configured in the RRC configuration information is the PDCCH monitoring period initially activated by the terminal device on DL BWP 2.
After the terminal device switches to DL BWP2, if the terminal device receives other indication information sent by the network device to indicate which PDCCH search space the terminal device should use on the DL BWP2 as the initially activated PDCCH search space and/or which PDCCH listening period the terminal device should use on the DL BWP2 as the initially activated PDCCH listening period, the terminal device determines the PDCCH search space initially activated by the terminal device on the DL BWP2 and/or the initially activated PDCCH listening period according to the other indication information. For example, the PDCCH received by the terminal device and carrying the working bandwidth switching information also carries identification information and/or fifth indication information of an activated PDCCH search space, and the fifth indication information indicates a monitoring period corresponding to the activated PDCCH search space in a bit map manner. The terminal device determines an initially activated PDCCH search space and/or an initially activated PDCCH monitoring period on the DL BWP2 according to the identification information and/or the fifth indication information of the activated PDCCH search space, and monitors the PDCCH on the initially activated PDCCH monitoring period of the initially activated PDCCH search space. In some embodiments, the operating bandwidth switching information may further include the fifth indication information. Alternatively, in some embodiments, the fifth indication information is not limited to be carried in PDCCH, but may also be carried in WUS or MAC CE.
For example, the network device configures DL BWP1 and DL BWP2 to the terminal device through RRC configuration information, currently active is DL BWP1, and DL BWP1 is configured with 2 PDCCH search spaces, where identification information of the 2 PDCCH search spaces is 1 and 2, respectively. Each PDCCH search space corresponds to one PDCCH monitoring period, and the currently activated PDCCH search space 2, and the PDCCH monitoring period corresponding to the PDCCH search space 2 is 4 slots. The terminal device monitors the PDCCH on the PDCCH BWP1 on the PDCCH search space with PDCCH monitoring period of 4 slots, as shown at 70 in fig. 7.
For DL BWP2, 1 PDCCH search space is configured, the identification information of the PDCCH search space is x, the PDCCH search space corresponds to 3 PDCCH monitoring periods, the identification information of the 3 PDCCH monitoring periods are 1,2, and 3 respectively, and the 3 PDCCH monitoring periods are 2 slots, 4 slots, and 8 slots respectively. Wherein, the PDCCH monitoring period of 8 slots is the PDCCH monitoring period initially activated on DL BWP2, and the PDCCH search space x is the PDCCH search space initially activated on DL BWP 2. As shown in fig. 7, at time t1, the terminal device receives operating bandwidth switching information sent by the network device instructing the terminal device to switch to DL BWP 2. If the working bandwidth switching information does not carry the identification information of the search space and/or the identification information of the monitoring period indicated by the display, the terminal device determines, according to the RRC configuration information, that the PDCCH search space initially activated on DL BWP2 is PDCCH search space x, and the PDCCH monitoring period initially activated on DL BWP2 is PDCCH monitoring period 3, that is, a PDCCH monitoring period of 8 slots. As shown in fig. 7, from time t2, the terminal device monitors the PDCCH on the PDCCH search space with PDCCH monitoring period of 8 slots on the DL BWP 2. Further, at time t3, the terminal device receives second indication information sent by the network device, where the second indication information indicates the adjusted target monitoring period in a bit map manner, for example, the bit map is 010, the terminal device determines that the adjusted target monitoring period is PDCCH monitoring period 2, that is, a PDCCH monitoring period of 4 slots, and switches to a PDCCH search space with a PDCCH monitoring period of 4 slots on DL BWP2 after time t3 to monitor the PDCCH. In this embodiment, the carrier for the second indication information may be WUS, MAC CE, or PDCCH.
It can be understood that, when the activated PDCCH monitoring period is indicated in a bitmap manner, only one PDCCH search space may be activated at each time, but at least one PDCCH monitoring period may be activated.
It can be understood that, in a CA scenario, for each serving cell of the terminal device, the terminal device may all adopt the method described in this embodiment to implement dynamic adjustment of the PDCCH monitoring period on each serving cell.
The following is a schematic illustration of the example of indicating the active listening period in a pattern. Specifically, the network device configures at least one DL BWP, for example, DL BWP1 and DL BWP2, to the terminal device through RRC configuration information. Currently active is DL BWP 1. For each DL BWP in the at least one DL BWP, at least one PDCCH search space is configured, where one PDCCH search space corresponds to at least one PDCCH monitoring period, and each PDCCH monitoring period configures corresponding identification information. For each DL BWP, at least one PDCCH search space configured for it includes at least one initially activated PDCCH search space. In addition, for each DL BWP, the network device further configures at least one of an activation order, an activation time, an activation duration, and an activation number of at least one PDCCH monitoring period in at least one PDCCH search space. After the terminal device switches to DL BWP2, if the terminal device does not receive other indication information from the network device to indicate which PDCCH search space the terminal device should use on the DL BWP2 as the initially activated PDCCH search space, the terminal device determines the initially activated PDCCH search space corresponding to DL BWP2 configured in the RRC configuration information as the PDCCH search space initially activated by the terminal device on the DL BWP 2.
After the terminal device switches to DL BWP2, if the terminal device receives fourth indication information sent by the network device to indicate which PDCCH search space the terminal device should use on the DL BWP2 as the initially activated PDCCH search space, the terminal device determines the activated PDCCH search space indicated by the fourth indication information as the PDCCH search space the terminal device initially activates on the DL BWP 2. For the initially activated PDCCH search space, the terminal device may activate at least one monitoring period corresponding to the initially activated PDCCH search space according to at least one of an activation sequence, an activation time, an activation duration, and an activation frequency of the at least one monitoring period corresponding to the initially activated PDCCH search space configured in the RRC configuration information. And monitoring the PDCCH in at least one monitoring period corresponding to the initially activated PDCCH search space.
For example, the network device configures DL BWP1 and DL BWP2 to the terminal device through RRC configuration information, currently active is DL BWP1, and DL BWP1 is configured with 2 PDCCH search spaces, where identification information of the 2 PDCCH search spaces is 1 and 2, respectively. Each PDCCH search space corresponds to one PDCCH monitoring period, and the currently activated PDCCH search space 2, and the PDCCH monitoring period corresponding to the PDCCH search space 2 is 4 slots. The terminal device monitors the PDCCH on the PDCCH BWP1 in the PDCCH search space with PDCCH monitoring period of 4 slots, as shown at 80 in fig. 8.
For DL BWP2, 1 PDCCH search space is configured, the identification information of the PDCCH search space is x, the PDCCH search space corresponds to 3 PDCCH monitoring periods, the identification information of the 3 PDCCH monitoring periods are 1,2, and 3 respectively, and the 3 PDCCH monitoring periods are 2 slots, 4 slots, and 8 slots respectively. The activation sequence corresponding to the 3 PDCCH monitoring periods is 3,1, 2. The period corresponding to the activation sequence is 40ms, and the number of activation times of each PDCCH monitoring period in the 40ms is 4. As shown in fig. 8, at time t1, the terminal device receives operating bandwidth switching information sent by the network device instructing the terminal device to switch to DL BWP 2. If the working bandwidth switching information does not carry identification information of the search space indicated by the display, the terminal device determines, according to the RRC configuration information, that the PDCCH search space initially activated on the DL BWP2 is the PDCCH search space x, and activates the 3 PDCCH monitoring periods according to at least one of an activation sequence, activation time, activation duration, activation times, and a period corresponding to the activation sequence of the 3 PDCCH monitoring periods corresponding to the PDCCH search space x. As shown in fig. 8, starting from time t2, the terminal device activates PDCCH monitoring period 3, PDCCH monitoring period 1 and PDCCH monitoring period 24 times in one period 40 ms. Correspondingly, the terminal device monitors the PDCCH on the PDCCH search space corresponding to the activated PDCCH monitoring period. Further, the terminal device may further receive second indication information sent by the network device, where the second indication information indicates the adjusted target listening period in a pattern manner. The terminal device determines the adjusted activation sequence of the 3 PDCCH monitoring periods corresponding to the PDCCH search space x according to the second indication information, activates the 3 PDCCH monitoring periods according to the adjusted activation sequence of the 3 PDCCH monitoring periods, and monitors the PDCCH in the activated PDCCH monitoring period.
It can be appreciated that when the activated PDCCH monitoring period is indicated in a pattern manner, only one PDCCH search space may be activated and one PDCCH monitoring period may be activated at each time.
It can be understood that, in a CA scenario, for each serving cell of the terminal device, the terminal device may all adopt the method described in this embodiment to implement dynamic adjustment of the PDCCH monitoring period on each serving cell.
In some embodiments, after the end device switches to the target working bandwidth, for example, DL BWP2, the network device may further send sixth indication information to the end device, where the sixth indication information indicates the activated control resource sets in a bitmap manner or a pattern manner, and the end device may use the activated control resource sets indicated by the sixth indication information as the control resource sets initially activated by the end device on the DL BWP 2. Optionally, the working bandwidth switching information sent by the network device to the terminal device includes the sixth indication information. Alternatively, the sixth indication information may be carried in the WUS, the MAC CE, or the PDCCH.
Optionally, at least one of the fourth indication information, the fifth indication information, and the sixth indication information is carried in a different WUS, MAC CE, or PDCCH.
In addition, after the terminal device determines the initially activated control resource set on the DL BWP2, the terminal device may further receive third indication information sent by the network device, where the third indication information indicates the adjusted target control resource set in a bitmap manner. Further, the terminal device monitors the PDCCH in the PDCCH search space and/or PDCCH monitoring period corresponding to the adjusted target control resource set. Wherein the third indication information may be carried in the WUS, the MAC CE, or the PDCCH.
Optionally, at least one of the first indication information, the second indication information, and the third indication information is carried in a different WUS, MAC CE, or PDCCH.
Fig. 9 is a schematic structural diagram of a terminal device provided in the present application, and as shown in fig. 9, the terminal device 90 includes: the receiving module 91 is configured to receive indication information sent by a network device, where the indication information is used to indicate an adjusted monitoring period of the terminal device; the listening module 92 is configured to listen to the corresponding resource set in the adjusted listening period.
