The network-side device 12 can include an access network device or a core network device, wherein the access network device can also be referred to as a Radio Access Network (RAN) device, a radio access network function, or a radio access network unit.

The base station is not limited to a specific technical term, and it is noted that only the base station in the NR system is taken as an example for introduction in the embodiments of the present application, and the specific type of the base station is not limited.

[0037] In addition, in order to facilitate the understanding of the technical solutions of the present application, the related technologies involved in the present application are briefly described as follows.

[0038] (1) SSB transmission method in 5G NR

[0039] For a primary cell (Pcell) or a primary secondary cell (PScell), the base station must transmit a periodic SSB, and the SSB period needs to be less than or equal to 20 ms to be successfully searched by the initial search terminal.

[0040] For an intra-band secondary cell (Scell), the base station can transmit an SSB, at which time the SSB-related parameters are configured when the Scell is added; or the base station can not transmit an SSB, at which time the SSB-related parameters are not configured when the Scell is added, and the terminal acquires the timing through the SSB on the Pcell.

[0041] For an inter-band Scell, the base station must transmit an SSB, and the SSB-related parameters are configured when the Scell is added.

[0042] (2) SSB to RO mapping rule in 5G NR

[0043] The configuration parameters of Physical Random Access Channel (PRACH) resource and SSB-RO are configured in System Information Block (SIB) 1. In NR, a cell can configure multiple Frequency Division Multiplex (FDM) PRACH transmission occasions (ROs, also known as Physical Random Access Channel transmission opportunities) in one time domain location where PRACH is transmitted. The number of FDM ROs at one time can be {1, 2, 4, 8}, which is determined by the higher layer parameter msg1-FDM.

[0044] The random access preamble can only be transmitted on the time domain resource configured by the parameter PRACHConfigurationIndex and the frequency domain resource configured by the parameter msg1-FDM. The PRACH frequency domain resource n RA ∈ {0, 1, …, M-1}, where M is equal to the higher layer parameter msg1-FDM. When initial access, the PRACH frequency domain resource n RA The RO resource is numbered in ascending order from the lowest frequency in the initial active uplink bandwidth part (initial active uplink BWP), otherwise, the PRACH frequency domain resource n RA The RO resource is numbered in ascending order from the lowest frequency in the active uplink BWP. For example, in FIG. 1b, the number of FDM ROs at one time is 8 (msg1-FDM = 8), and the RO resources are numbered in order from low to high in frequency as RO#0 ~ RO#7.

[0045] In NR, there is an association between RO and actually transmitted synchronization signal (SS / PBCH block, SSB, also known as physical broadcast channel block). RO is associated to SSB in the order of frequency domain (from low frequency to high frequency) first and then time domain. One SSB can be associated with multiple consecutive ROs, or one RO can be associated with multiple SSBs (in this case, different SSBs correspond to different Preambles), which is configured by the network through the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB. For example, oneEighth represents that one SSB is associated with 8 consecutive ROs, and eight represents that 8 SSBs are associated with one RO. {n4, n8, n12, …} represents the number of Preambles associated with each SSB on one RO, for example, n4 represents that the number of Preambles associated with each SSB on one RO is 4, and n8 represents that the number of Preambles associated with each SSB on one RO is 4.

[0046] After all SSBs are associated with ROs for one round, an SSB-RO mapping cycle is formed. One SSB-to-RO association period can contain one or more SSB-RO mapping cycles. One SSB-to-RO association pattern period can contain one or more SSB-to-RO association periods, and the mapping of SSB to RO is repeated in the association pattern period, and the association pattern period is at most 160 ms.

[0047] Generally, the base station can use different beams to transmit different SSBs, and the number of SSBs is configured by the parameter ssb-PositionsInBurst. For frequency range 1 (Frequency range 2, FR2), the maximum number of SSBs is 64. The terminal selects the RO associated with the SSB with good signal strength and the “RO and preamble combination” of the SSB according to the received downlink beam / SSB strength, and transmits Msg1. In this way, the network can determine the SSB selected by the terminal according to the received Preamble of the RO / “RO and preamble combination”, and transmits Msg2 on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0048] For example, in FIG. 1b, the number of ROs of FDM at one time is 8, the number of actually transmitted SSBs is 4, i.e., SSB#0, SSB#1, SSB#2, and SSB#3, and each SSB is associated with 2 ROs. If the terminal determines to send PRACH / Msg1 on the RO corresponding to SSB#0, the terminal selects one of RO#0 and RO#1 to send PRACH.

[0049] For example, in FIG. 1c, the number of ROs of FDM at one time is 2, the number of actually transmitted SSBs is 8, i.e., SSB#0, SSB#1, …, and SSB#7, and each 2 SSBs are associated with 1 RO. When multiple SSBs share one RO, the preamble set associated with the multiple SSBs is different, i.e., the same preamble cannot belong to the preamble sets associated with different SSBs at the same time. For example, in FIG. 1c, RO#0 has 60 preambles, in which the preambles with index 0-29 are associated with SSB#0, and the preambles with index 30-59 are associated with SSB#1. It should be noted that each square shown in FIG. 1c draws an RO, not an SSB, in which the SSB indicates which SSB(s) the RO is associated with.

[0050] Before the terminal sends PRACH, the terminal first selects an SSB with a reference signal received power (RSRP) higher than a threshold according to the received beam (or SSB). If there are multiple SSBs with RSRP higher than the threshold, the terminal can select any SSB with RSRP higher than the threshold. When there is no SSB with RSRP higher than the threshold, the terminal selects an SSB based on implementation.

[0051] Based on network (NW) configuration, the terminal obtains the correspondence between SSBs and ROs. After selecting an SSB, the RO corresponding to the selected SSB is used as the RO for sending PRACH / Preamble / Msg1. If the selected SSB is associated with multiple ROs, the terminal can select one of the ROs to send PRACH / Preamble / Msg1.

[0052] For example, in the example shown in FIG. 1b, assuming that the terminal selects SSB#1, the terminal can select one of RO#2 and RO#3 for PRACH / Msg1 transmission; in the example shown in FIG. 1c, assuming that the terminal selects SSB#1, the terminal can select the available RO closest to the current time in the RO (RO#0 or 4) associated with SSB#1 for PRACH / Msg1 transmission. In the selected RO, the terminal selects a preamble in the preamble set associated with the selected SSB for PRACH transmission. As shown in FIG. 1c, an RO is associated with 2 SSBs, so in the available preamble set associated with the SSB in an RO, the preambles are divided into two subsets, each corresponding to an SSB. The UE will select a preamble sequence in the preamble subset corresponding to the selected SSB for PRACH / Msg1 transmission.

[0053] Based on this, the technical solutions provided by the embodiments of the present application will be described in detail below in combination with the drawings and some embodiments and application scenarios thereof.

[0054] As shown in FIG. 2, a flowchart of a reference signal transmission method 200 provided by an exemplary embodiment of the present application is shown, which can be executed by a terminal, but is not limited thereto, and can be executed by hardware and / or software installed in the terminal. In this embodiment, the method 200 can at least include the following steps.

[0055] S210, the terminal receives a first reference signal from a network side device.

[0056] Wherein, the same kind of reference signal is configured with at least one signal type, and the signal type of the first reference signal belongs to the at least one signal type. That is, in the present application, the same kind of reference signal (such as SSB, etc.) received by the terminal can be one signal type, or different signal types. Therefore, for future communication networks such as 6G, flexible use of reference signals of different signal types can be used to realize flexible transmission of reference signals corresponding to different beams or beam groups, achieve the purpose of large area coverage, narrow beam coverage, etc., avoid the problem of complex uplink signals caused by the difference between the round-trip time (RTT) of different terminals in the area covered by the same beam or beam group being too large, and ensure the system performance of the communication system.

[0057] In this embodiment, one or more signal types configured for the same kind of reference signal (such as SSB, etc.) can be realized by protocol agreement or network configuration, etc., which is not limited herein. It should be noted, however, that for the terminal and the network side device, the understanding of the signal type of the reference signal by the two should be consistent.

[0058] In some implementations, the signal type of the reference signal provided by the present application can include, but is not limited to, at least one of the first type and the second type for the same reference signal.

[0059] The first type of reference signal can also be referred to as an on demand reference signal, which can be understood as a reference signal that is activated or deactivated on demand, i.e., activated when a reference signal is needed and deactivated when a reference signal is not needed. Thus, through the activation or deactivation of the reference signal, not only can the flexible control of the reference signal corresponding to different beams or beam groups be realized, but also the network side device can independently control the transmission complexity of the reference signal, thereby reducing the network power consumption. When the first type of reference signal is deactivated, i.e., the first type of reference signal is in a non-activated state, the terminal does not need to perform detection on the corresponding reference signal resource, thereby also reducing the blind detection complexity of the terminal.

[0060] In addition, in the present embodiment, the first type of reference signal can also be used to assist other uplink transmissions, such as wireless link quality detection, etc., to improve resource utilization.

[0061] It is worth noting that the first type of reference signal can be any downlink synchronization signal or broadcast signal that can be activated or deactivated or switched on and off. Taking the reference signal SSB as an example, it can be a part of the SSB index on the activated SSB, or it can be all SSB indexes activated.

[0062] The second type of reference signal can also be referred to as a normal reference signal, which can be understood as a reference signal configured to be activated or effective. That is, compared with the first type of reference signal, the reference signal configured as the second type does not need to be activated, and can be directly transmitted or received after being configured.

[0063] In the present embodiment, the second type of reference signal can be understood as a reference signal used in the 5G NR communication system, and the first type of reference signal is a signal type introduced to adapt to future networks such as 6G. It can be that part or all of the reference signals used in the 5G NR communication system are reconfigured as the first type, or it can be a new signal type added on the basis of the reference signals used in the 5G NR communication system, which is not limited in the present embodiment.

[0064] It is worth noting that the "reference signal" mentioned in the context of the present application can include but is not limited to one or more of SSB, broadcast signal, broadcast channel (Physical broadcast channel, PBCH), system message, control channel, channel state information reference signal (Channel State Information Reference Signal, CSI-RS), positioning reference signal (Positioning Reference Signal, PRS), phase reference signal (Tracking Reference Signal, TRS), etc. That is, the present application can configure one or more signal types for reference signals such as SSB, CSI-RS, PRS, TRS, broadcast signal, broadcast channel, system message, control channel, etc. respectively to meet different communication requirements in future communication systems such as 6G, such as signal synchronization, signal measurement, wireless link measurement, positioning measurement, etc. without limitation.

[0065] When the "reference signal" is the aforementioned SSB, the SSB can also be referred to as any signal containing at least one of synchronization signal, broadcast signal, broadcast channel, system message, downlink broadcast channel, control channel, other reference signal, without limitation.

[0066] In some embodiments, for the case of configuring at least one signal type for the same reference signal as mentioned above, the present embodiment also provides a configuration method of physical resources for different signal types of the same reference signal, so that the reference signals of different signal types are in specific physical resources, to flexibly configure different beams or beam groups (corresponding to different signal types of reference signals. Especially for the multi-TRP (mTRP) scenario, through the configuration of specific physical resources, it can also ensure that the terminal can be covered by multiple TRPs in the same area within a certain time. It should be noted that the beam mentioned in the context of the present application can also be represented as a certain reference signal or a certain group of reference signals, or a certain spatial filter of a certain reference signal or a certain group of reference signals, etc. without limitation.

[0067] For example, the configuration method of the signal type of the reference signal can include but is not limited to: configuring different or independent at least two first objects for the same reference signal; wherein the reference signals corresponding to each of the first objects are of different signal types, and the first object includes at least one of time domain resource, frequency domain resource, spatial resource, reference signal sequence, reference signal resource configuration.

[0068] For the case that the first object is a time domain resource, it can be understood that at least two different or independent time domain resources are associated with the same reference signal. For example, assuming that the reference signal is an SSB, and the same reference signal is configured with two signal types, such as a first type and a second type, then the SSB associated with the time domain resource 1 can be of the first type, and the SSB associated with the time domain resource 2 can be of the second type.

[0069] For the case that the first object is a frequency domain resource, it can be understood that at least two different or independent frequency domain resources are associated with the same reference signal. For example, assuming that the reference signal is an SSB, and the same reference signal is configured with two signal types, such as a first type and a second type, then the SSB associated with the frequency domain resource 1 can be of the first type, and the SSB associated with the frequency domain resource 2 can be of the second type.

[0070] For the case that the first object is a spatial resource, it can be understood that at least two different or independent spatial resources are associated with the same reference signal. For example, assuming that the reference signal is an SSB, the spatial resource is a reference signal index, and the same reference signal is configured with two signal types, such as a first type and a second type, then the SSB associated with the index 1 can be of the first type, and the SSB associated with the index 2 can be of the second type.

[0071] For the case that the first object is a reference signal sequence, it can be understood that at least two different or independent reference signal sequences are associated with the same reference signal. For example, assuming that the reference signal is an SSB, and the same reference signal is configured with two signal types, such as a first type and a second type, then the SSB associated with the reference signal sequence 1 can be of the first type, and the SSB associated with the reference signal sequence 2 can be of the second type.

[0072] For the case that the first object is a reference signal resource configuration, it can be understood that the same reference signal is associated with at least two different or independent reference signal resource configurations. For example, assuming that the reference signal is an SSB, and the same reference signal is configured with two signal types, such as a first type and a second type, then in the case that the SSB is associated with two different or independent reference signal resource configurations, such as a reference signal resource configuration 1 and a reference signal resource configuration 2, the signal type of the SSB associated with the reference signal resource configuration 1 can be the first type, and the signal type of the SSB associated with the reference signal resource configuration 2 can be the second type. Alternatively, the reference signal resource configuration is used to describe the time domain resource, frequency domain resource, space domain resource, etc. when the reference signal is transmitted or received.

[0073] In this embodiment, for the same reference signal, different signal types and / or different resource configurations are provided, so that the reference signals of different signal types are in specific physical resources, thereby achieving the purpose of flexibly configuring different types of reference signals corresponding to different beams or beam groups, and further supporting switching or hopping of different beams or beam groups. Especially for the case of mTRP, the terminal can be covered by multiple TRPs in the same area at a specific time according to the resource characteristics of the reference signals corresponding to different TRPs.

[0074] In some embodiments, for different signal types of the same reference signal, the embodiment further provides a resource multiplexing mode corresponding to the reference signals of different signal types, to realize resource multiplexing between reference signals of different signal types and improve resource utilization.

[0075] In an implementation manner, the resource multiplexing mode corresponding to the reference signals of different signal types can include at least one of 11)-12) below.

[0076] 11) Resource multiplexing is performed in each time unit as a granularity, that is, for the same reference signal, independent or different signal types can be configured on different time units.

[0077] For example, assuming a 160ms time window, which can include multiple time units, and each time unit is configured with an index, then the signal type of the reference signal in the time unit with an even index can be configured as the second type, and the signal type of the reference signal in the time unit with an odd index can be configured as the second type.

[0078] For example, assuming a time window of 160 ms, and within the time window, the signal type of the reference signal contained in each 20 ms is described by one bit. For example, the bitmap "01010101" indicates that the signal type of the reference signal in the 1st, 3rd, 5th, 7th 20 ms is the first type, and the signal type of the reference signal in the 2nd, 4th, 6th, 8th 20 ms is the second type.

[0079] It should be noted that resource reuse with each time unit as the granularity can also be understood as resource reuse for all physical reference signals without considering or distinguishing the index of the reference signal or the index of the reference signal group.

[0080] 12) Resource reuse with the index of each reference signal or the index of each reference signal group as the granularity, i.e., for the same reference signal, different reference signal indexes or reference signal group indexes can be configured with independent or different signal types.

[0081] For example, for the index of the reference signal, assuming that there are two reference signal indexes, such as index 0 and index 1, then index 0 corresponds to the first type of reference signal in each odd 20 ms and corresponds to the second type of signal in each even 20 ms; index 1 corresponds to the first type of reference signal in each odd 40 ms and corresponds to the second type of reference signal in each even 40 ms. Wherein, "odd" is the index of the 20 ms time unit, and "even" is the index of the 40 ms time unit.

[0082] Another implementation manner is that the resource reuse mode corresponding to the reference signals of different signal types is the same at a certain granularity, and the certain granularity includes any one of a time unit, an index of a reference signal, and an index of a reference signal group. For example, assuming that the certain granularity is the index of the reference signal, and the same reference signal corresponds to two indexes, such as index 0 and index 1, then index 0 corresponds to the first type of reference signal in each odd 20 ms and corresponds to the second type of reference signal in each even 20 ms; and index 1 corresponds to the first type of reference signal in each odd 20 ms and corresponds to the second type of reference signal in each even 20 ms, which is the same as index 0.

[0083] In some embodiments, for the aforementioned first type of reference signal, since it is needed to control when to open the communication under certain beams by activating or deactivating it to realize beam switching or hopping, in the present embodiment, the activation condition (i.e., the subsequent first condition) and the deactivation condition (i.e., the subsequent second condition) of the first type of reference signal are also provided. Among them, the "activation condition" is used to realize the activation or request activation or activation signal transmission, etc. of the first type of reference signal, and the "deactivation condition" is used to realize the deactivation or request deactivation or deactivation signal transmission, etc. of the first type of reference signal.

[0084] Based on this, in an implementation manner, the terminal activates or requests to activate the first type of reference signal in the case where the first condition is met.

[0085] Among them, the first condition can but is not limited to include at least one of the following conditions 001-conditions 011.

[0086] Condition 001: The terminal cannot access the network through the terrestrial network (TN). In this case, the terminal can activate the first type of reference signal to try to access the future network such as 6G through the activated first type of reference signal to realize communication.

[0087] Condition 002: The terminal does not query the TN network, or does not query the TN network that meets the S criterion. In this case, the terminal can activate the first type of reference signal to try to access the future network such as 6G through the activated first type of reference signal to realize communication.

[0088] Among them, the S criterion refers to that the reference signal received power or its function value of the terminal in the cell or specific network search process is greater than a threshold A, and the reference signal received quality or its function value is greater than a threshold B, and the threshold A and the threshold B are realized by a protocol agreement or the like.

[0089] Condition 003: The terminal is barred by the TN network. In this case, the terminal can activate the first type of reference signal to try to access the future network such as the NTN network through the activated first type of reference signal to realize communication.

[0090] Condition 004: The terminal cannot access the network through a specific physical random access channel (PRACH), wherein the specific PRACH is a PRACH that is not subjected to time advance pre-compensation processing and is associated with the second type of reference signal.

[0091] For example, when the PRACH resource associated with the second type of reference signal is a PRACH resource without time advance compensation, the terminal cannot or has no ability to access the network through the PRACH resource corresponding to the PRACH, in this case, in order to realize network access, the terminal needs to initiate access using the PRACH resource with pre-compensation, and the signal type of the reference signal associated with it is the first type, so it is necessary to first initiate the activation of the first type of reference signal, and then realize network access based on the activated first type of reference signal.

[0092] Condition 005: There is buffer data in the terminal, wherein the buffer data includes data corresponding to at least one of emergency services and emergency calls. That is, when there is buffer data corresponding to at least one of emergency services and emergency calls in the terminal, the first type of SSB needs to be activated to ensure timely transmission of emergency services or emergency calls.

[0093] Condition 006: The target network sends a paging alert or fails to continuously page the terminal. In this case, the terminal can activate the first type of reference signal to page through the beam corresponding to or associated with the activated first type of reference signal, thereby improving the success rate of paging.

[0094] The target network can be activated, wherein the target network is the network where the terminal is located or the network side device serving the terminal.

[0095] Condition 007: The signal type of the reference signal selected by the target network is the first type.

[0096] Condition 008: The signal type of a specific reference signal in the reference signal selected by the target network is the first type, wherein the specific reference signal is determined according to the signal measurement energy or quality of the wake-up signal (WUS) associated with it, or the specific reference signal is determined according to the location of the terminal.

[0097] The specific reference signal can be, but is not limited to, the best reference signal, such as the signal measurement energy or quality of the WUS associated with the first type of reference signal being the best.

[0098] Condition 009: The number of reference signals of the first type in the reference signal selected by the target network exceeds or is not less than a first threshold.

[0099] It can be understood that the first threshold, the second threshold, the third threshold and the like mentioned in the context of the present application can be determined by agreement, high layer configuration or network side configuration, and the like, which is not limited herein.

[0100] Condition 010: the target network detects the WUS signal sent by the terminal, and the signal measurement energy or quality of the WUS signal is not less than a second threshold, wherein the signal type of the reference signal corresponding to the WUS signal is the first type.

[0101] The signal measurement energy or quality can be characterized by one or more of reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-noise ratio (SIN), and signal-to-noise and interference ratio (SINR).

[0102] Condition 011: the signal quality of the reference signal of the second type meets the radio link failure (RLF) condition or the beam failure (BF) condition.

[0103] It is worth noting that for the foregoing conditions 001-005 and condition 011, the terminal can determine that one or more of the foregoing conditions are met, and request the network side device to activate the reference signal of the first type, or can autonomously activate the reference signal of the first type according to the agreement and notify the network side device of the activation information, such as which reference signals on which resources are activated, and the like, to ensure that the network side device and the terminal have a consistent understanding of the activation of the reference signal of the first type, to ensure the correct sending and receiving of the reference signal of the first type.

[0104] For the foregoing conditions 006-010, the network side device can determine that one or more of the foregoing conditions 006-010 are met, activate the reference signal of the first type, and instruct the terminal to activate, such as which reference signals on which resources are activated, and the like, to ensure that the network side device and the terminal have a consistent understanding of the activation of the reference signal of the first type, to ensure the correct sending and receiving of the reference signal of the first type. That is, when the terminal receives the activation indication information sent by the network side device, it is determined that one or more of the foregoing conditions 006-010 are met.

[0105] As to which one of the aforementioned conditions 001-conditions 011 the first condition comprises, it can be achieved by agreement, high layer configuration, etc., which is not limited here.

[0106] Corresponding to the activation or requested activation of the aforementioned first type of reference signal, in another implementation, the terminal can deactivate or request to deactivate the first type of reference signal when a second condition (i.e. deactivation condition) is met. Wherein the second condition can include but is not limited to at least one of the following conditions 11-conditions 17.

[0107] Condition 11: The terminal can access the network through the TN network.

[0108] Condition 12: The terminal can access the network through a specific PRACH, wherein the specific PRACH is a PRACH that is not pre-compensated for time advance and is associated with the second type of reference signal.

[0109] For example, when the PRACH resource associated with the second type of reference signal is a PRACH resource without time advance compensation, and the terminal can already access the network through the corresponding PRACH. Then in this case, it is not necessary to initiate access using the PRACH resource with pre-compensation, and the first type of reference signal associated with it is in an activated state, then in order to save energy, the terminal can deactivate or request to deactivate the first type of reference signal.

[0110] Condition 13: The signal type of the reference signal selected by the target network is the second type.

[0111] Condition 14: The signal type of a specific reference signal in the reference signal selected by the target network is the second type.

[0112] Condition 15: The number of reference signals of the first type in the reference signal selected by the target network does not exceed or is less than a first threshold.

[0113] Condition 16: The target network detects a WUS signal sent by the terminal, and the signal measurement energy or quality of the WUS signal is less than a second threshold, wherein the signal type of the reference signal corresponding to the WUS signal is the first type.

[0114] Condition 17: The second type of reference signal does not meet the RLF condition or the BF condition.

[0115] It is worth noting that for the aforementioned conditions 11-conditions 12 and condition 17, the terminal can determine that one or more of them are met, and request the network side device to deactivate the first type of reference signal, or can autonomously deactivate the first type of reference signal according to the protocol agreement and notify the network side device of the deactivation information, such as which reference signals on which resources are deactivated, etc., to ensure that the network side device and the terminal have a consistent understanding of the activation of the first type of reference signal, and avoid resource waste.

[0116] For the aforementioned conditions 13-conditions 16, the network side device can determine that one or more of the aforementioned conditions 13-conditions 16 are met, and deactivate the first type of reference signal and instruct the terminal to deactivate, such as which reference signals on which resources are deactivated, etc., to ensure that the network side device and the terminal have a consistent understanding of the deactivation of the first type of reference signal, and avoid resource waste. That is, when the terminal receives the deactivation indication information sent by the network side device, it is determined that one or more of the aforementioned conditions 13-conditions 16 are met.

[0117] As for which of the aforementioned conditions 13-conditions 17 the second condition includes, it can be achieved by protocol agreement, high-level configuration, etc., which is not limited here.

[0118] It is worth noting that for the aforementioned activation or deactivation of the first type of reference signal, it can also be understood as: respectively allowing or not allowing the network side device to send the first type of reference signal on the corresponding first type of reference signal resource, and / or, respectively allowing or not allowing the terminal to detect (i.e. receive) the first type of reference signal on the corresponding first type of reference signal resource.

[0119] In this embodiment, through the configuration of the activation condition and the deactivation condition, the beam switching can be flexibly controlled, and it is determined when to open or close the communication under which beam, to ensure the system performance of the communication system.

[0120] In some embodiments, for the case of one or more different signal types configured for the same reference signal, as shown in FIG. 3, the transmission method of the reference signal can further include S220, the content of which is as follows.

[0121] S220, the terminal performs at least one of RLF detection and BF detection based on the first reference signal.

[0122] In some embodiments, the first reference signal can be determined according to at least one of the following 21)-24).

[0123] 21) The reference signal actually transmitted by the network side device.

[0124] For example, the terminal and the network-side device can determine the reference signal actually transmitted by the network-side device as the first reference signal for the terminal to perform RLF detection, BF detection, etc.

[0125] 22) a reference signal in an activated state.

[0126] For example, the terminal and the network-side device can determine the reference signal in an activated state as the first reference signal for the terminal to perform RLF detection, BF detection, etc.

[0127] 23) a reference signal in an activated state and in effect.

[0128] For example, the terminal and the network-side device can determine the reference signal in an activated state and in effect as the first reference signal for the terminal to perform RLF detection, BF detection, etc.

[0129] 24) a reference signal within a first time window.

[0130] For example, the terminal and the network-side device can determine the reference signal within a first time window as the first reference signal for the terminal to perform RLF detection, BF detection, etc. The first time window can be a time window configured by a protocol or configured for reference signal measurement, or can be a configured time window corresponding to a current beam, without limitation.

[0131] Through the above-mentioned 21) to 24), it is clear that when performing RLF detection or BF detection, it is necessary to consider when or what reference signal, so as to avoid RLF detection or BF detection errors and ensure the performance of the communication system.

[0132] In some embodiments, the detection manner of performing RLF detection based on the first reference signal in S220 can include but is not limited to at least one of the following manner 11 to manner 12.

[0133] Manner 11: performing the RLF detection according to the signal performance of the first type of reference signal and the second type of reference signal included in the first reference signal.

[0134] It can be understood that in manner 11, the first type and the second type of reference signal are considered simultaneously when performing RLF detection, i.e., the performance of the two types of reference signals is used to judge RLF. For example, the performance of the two types of reference signals can be used to judge RLF under a wide beam pattern.

[0135] In some implementations, when the RLF detection is performed according to the signal performance of the first type of reference signal and the second type of reference signal comprised in the first reference signal in manner 11, the detection procedure can at least include that the terminal triggers or indicates or determines the RLF in the case that a third condition is satisfied. The third condition can include at least one of conditions 31-35.

[0136] Condition 31: the signal measurement results or function values of all the second type of reference signals and at least one of the first type of reference signals are lower than a third threshold.

[0137] Condition 32: the signal measurement results or function values of all the second type of reference signals and all the first type of reference signals are lower than a fourth threshold.

[0138] Condition 33: the signal measurement result or function value of at least one of the first type of reference signals is lower than a fifth threshold.

[0139] Condition 34: the signal measurement result or function value of at least one of the second type of reference signals is lower than a sixth threshold.

[0140] Condition 35: the signal measurement results or function values of all the first type of reference signals and at least one of the second type of reference signals are lower than a seventh threshold.

[0141] In some other implementations, the RLF detection according to the first type of reference signal and the second type of reference signal comprised in the first reference signal in manner 11 can at least further include that a first operation is performed in the case that a fourth condition is satisfied.

[0142] The fourth condition can include at least one of conditions 41-42, but is not limited to the same.

[0143] Condition 41: the signal measurement result or function value of at least one of the first type of reference signals is not lower than a fifth threshold.

[0144] Condition 42: the signal measurement result or function value of at least one of the second type of reference signals is not lower than a sixth threshold.

[0145] The first operation can include at least one of operations 11-14, but is not limited to the same.

[0146] Operation 11: not indicating or not triggering the RLF.

[0147] Operation 12: stopping the RLF detection related timer or counter.

[0148] Operation 13: Restarting the RLF detection related timer or counter.

[0149] Operation 14: Determining or considering that the radio link quality is recovered.

[0150] Manner 12: Performing the RLF detection according to the signal performance of the first type of reference signal or the second type of reference signal comprised in the first reference signal. It can be understood that in manner 12, only the first type or the second type of reference signal is considered when performing the RLF detection, i.e. the RLF is determined only according to the performance of one type of reference signal.

[0151] In some implementations, the RLF detection according to the signal performance of the first type of reference signal or the second type of reference signal comprised in the first reference signal in manner 12 can at least include that, in the case of performing the RLF detection according to the signal performance of the first type of reference signal comprised in the first reference signal, and all the signal measurement results of the first type of reference signal or the function values thereof are lower than a third threshold, or in the case of performing the RLF detection according to the signal performance of the second type of reference signal comprised in the first reference signal, and all the signal measurement results of the second type of reference signal or the function values thereof are lower than a fourth threshold, the terminal triggers or indicates the RLF.

[0152] In some implementations, the RLF detection according to the signal performance of the first type of reference signal or the second type of reference signal comprised in the first reference signal in manner 12 can at least include that, in the case of performing the RLF detection according to the first type of reference signal comprised in the first reference signal, and at least one signal measurement result of the first type of reference signal or the function value thereof is higher than a fifth threshold, or in the case of performing the RLF detection according to the second type of reference signal comprised in the first reference signal, and at least one signal measurement result of the second type of reference signal or the function value thereof is higher than a sixth threshold, a second operation is performed.

[0153] The second operation can include but is not limited to at least one of the following operations 21-23.

[0154] Operation 21: Not indicating or not triggering the RLF.

[0155] Operation 22: Canceling the RLF.

[0156] Operation 23: Resetting the RLF related timer or counter.

[0157] In some embodiments, the aforementioned RLF detection provided in the aforementioned manner 11, manner 12 can be performed for a current one or more cells or primary cell (Pcell) or physical cell identifier (PCI) or the like. In addition, in the present embodiment, the first reference signal used for the RLF detection corresponds to at least one beam group or beam pattern, which is not limited here.

[0158] In some embodiments, the aforementioned RLF detection provided in the aforementioned manner 11, manner 12 can also be performed per beam group or beam pattern, for example, when performing RLF detection per beam group, the performance of the RLF can be determined by considering both types of reference signals (such as the first type and the second type of reference signal) as shown in manner 11, or only considering one type of reference signal (such as the first type or the second type of reference signal) as shown in manner 12, which is not limited here.

[0159] Of course, for the aforementioned RLF detection, whether to consider using one or two or multiple signal types can be achieved by protocol agreement, high-level configuration, etc., or can be determined according to at least one of the following 31)-33).

[0160] 31) The signal type of the reference signal included in the beam group or beam pattern.

[0161] For example, in the case where the beam group or beam pattern used for RLF detection includes the first type or the second type of reference signal, then the reference signal used for RLF is the first type or the second type of reference signal; or in the case where the beam group or beam pattern used for RLF detection includes the first type and the second type of reference signal, then the reference signal used for RLF includes the first type and the second type of reference signal.

[0162] 32) The size of the measurement value of the reference signal.

[0163] For example, for the same type of reference signal, when the signal type of the reference signal with a measurement value less than a certain threshold value only includes the first type, then the reference signal used for RLF is the first type of reference signal, and when the signal type of the reference signal with a measurement value less than a certain threshold value includes the first type and the second type, then the reference signal used for RLF includes the first type and the second type of reference signal.

[0164] Optionally, the measurement value can be characterized by RSRP, RSRQ, SIN, SINR, etc.

[0165] 33) a size of a physical downlink control channel (PDCCH) block error rate (BLER).

[0166] For example, for the same reference signal, when the PDCCH BLER is greater than a certain threshold, the signal type of the corresponding reference signal only includes the first type, then the reference signal used for RLF is the first type of reference signal, and when the PDCCH BLER is greater than a certain threshold, the signal type of the corresponding reference signal includes the first type and the second type, then the reference signal used for RLF includes the first type and the second type of reference signal.

[0167] In this embodiment, the PDCCH BLER can be understood as a hypothesis PDCCH BLER or a predefined PDCCH BLER, etc.

[0168] In some embodiments, in the RLF detection process, the reference signals of different types can also satisfy at least one of the following 41)-44).

[0169] 41) The reference signals of different signal types correspond to different weights (or weight values).

[0170] The weight corresponding to the reference signal refers to the proportion of the measurement result of the reference signal in the multiple measurement results used to judge the RLF when the measurement result based on the reference signal is used for RLF detection.

[0171] 42) The reference signals of different signal types correspond to different radio link detection windows or periods, that is, for the same reference signal, different signal types can use different radio link detection windows or periods.

[0172] 43) When the radio link is in a specific state, the first type of reference signal is used for RLF detection, wherein the specific state is an in-sync (IS) state or an out-of-sync state, that is, only in the in-sync state or the out-of-sync state, the measurement of the first type of reference signal is used or planned to be used for RLF detection.

[0173] For example, when the radio link is in the in-sync state, the first type of reference signal can be used for RLF, and when the radio link is in the out-of-sync state, the second type of reference signal can be used for RLF, and vice versa.

[0174] 44) when the number of radio links in out-of-sync state reaches an eighth threshold, RLF detection is performed using the first type of reference signal, i.e. in the middle of the procedure.

[0175] For example, when the number of radio links in out-of-sync state does not reach the eighth threshold, RLF is not triggered, but the measurement of the reference signal of the first Lexi is activated, and when the number of radio links in out-of-sync state reaches the eighth threshold, RLF based on the first type of reference signal is triggered.

[0176] In some embodiments, for the aforementioned RLF detection, the signal quality threshold configured therefor can consider multiple groups of factors, so as to flexibly control the radio link failure condition of the target user under different reference signals (or beams) or reference signal (or beam) types.

[0177] Based on this, as a possible implementation manner, the determination manner of the signal quality threshold for the RLF detection can include but is not limited to at least one of the following 51)-54).

[0178] 51) determination is performed with each reference signal index or reference signal group index as granularity.

[0179] For example, for some beams or beam groups, if the beam is relatively narrow, the signal quality threshold can be set to be relatively large, so as to avoid too many users in the same narrow beam, and the capacity in such beam coverage range is also not so large; vice versa.

[0180] 52) determination is performed with the signal type of each reference signal as granularity.

[0181] For example, a signal quality threshold is defined for the second type of reference signal, and another signal quality threshold is defined for the first type of reference signal. Meanwhile, the signal quality threshold corresponding to the first type of reference signal can be set to be relatively small, so as to enable the terminal in the edge cell to consider radio link failure in the case of very poor signal quality; and the signal quality threshold corresponding to the second type of reference signal can be set to be relatively large, so as to enable most of the non-edge terminals to have a high point of signal quality requirement, such as using the first type of reference signal or determining radio link failure as long as it is below a certain higher signal quality threshold, so as to ensure the performance of the communication system.

[0182] 53) determination is performed with each time unit as granularity. That is, independent or different signal quality thresholds are configured for the reference signals in different first time units.

[0183] For example, assuming a time window of 150 ms, the reference signal measurement in even time units refers to a first signal quality threshold, and the reference signal measurement in other time units refers to a second signal quality threshold, wherein the first signal quality threshold and the second signal quality threshold can be the same or different.

[0184] 54) In the mTRP scenario, the signal quality threshold is independently configured for different TRPs, or the same signal quality threshold is configured for different TRPs.

[0185] In this embodiment, a flow of RLF detection based on reference signals of different signal types is provided, and it is clear when the corresponding reference signal can be used for RLF detection, thereby avoiding wireless link detection errors.

[0186] In some embodiments, the detection manner of performing BF detection based on the first reference signal in S220 is similar to the aforementioned RLF detection, which can include but is not limited to at least one of the following manners 21-22.

[0187] Manner 21: performing the BF detection according to the signal performance of the first type of reference signal and the second type of reference signal included in the first reference signal.

[0188] It can be understood that in manner 21, the first type and the second type of reference signal are considered simultaneously when performing BF detection, that is, BF is judged according to the performance of the two types of reference signals. For example, BF under a wide beam pattern can be judged according to the performance of the two types of reference signals.

[0189] In some implementations, when performing the BF detection according to the signal performance of the first type of reference signal and the second type of reference signal included in the first reference signal in manner 21, the detection process can at least include: in the case of satisfying a fifth condition, the terminal triggers or indicates or determines the BF. Wherein the fifth condition can include at least one of the following conditions 51-55.

[0190] Condition 51: the signal measurement results or function values of all second type of reference signals and at least one first type of reference signal are lower than a ninth threshold.

[0191] Condition 52: the signal measurement results or function values of all the second type of reference signals and all the first type of reference signals are lower than a tenth threshold.

[0192] Condition 53: the signal measurement result or function value of at least one first type of reference signal is lower than an eleventh threshold.

[0193] Condition 54: the signal measurement result or function value of at least one second type of reference signal is lower than a twelfth threshold value.

[0194] Condition 55: the signal measurement result or function value of all first type of reference signals and at least one second type of reference signal is lower than a thirteenth threshold value.

[0195] In some implementations, the BF detection according to the first type of reference signal and the second type of reference signal comprised in the first reference signal in manner 21 can further include: performing a third operation when a sixth condition is satisfied.

[0196] The sixth condition can include, but is not limited to, at least one of the following conditions 61-62.

[0197] Condition 61: the signal measurement result or function value of at least one first type of reference signal is not lower than an eleventh threshold value.

[0198] Condition 62: the signal measurement result or function value of at least one second type of reference signal is not lower than a twelfth threshold value.

[0199] The third operation can include, but is not limited to, at least one of the following operations 31-34.

[0200] Operation 31: not indicating or not triggering BF.

[0201] Operation 32: stopping the BF detection related timer or counter.

[0202] Operation 33: restarting the BF detection related timer or counter.

[0203] Operation 34: determining or considering that the radio link quality has recovered.

[0204] Manner 22: performing the BF detection according to the signal performance of the first type of reference signal or the second type of reference signal comprised in the first reference signal. It can be understood that in manner 22, only the first type or the second type of reference signal is considered when performing the BF detection, i.e., only the performance of one type of reference signal is used to determine the BF.

[0205] In some implementations, the BF detection according to the signal performance of the first type of reference signal or the second type of reference signal comprised in the first reference signal in the manner 22 can at least include: in the case that the BF detection is performed according to the signal performance of the first type of reference signal comprised in the first reference signal, and the signal measurement result or the function value of all the first type of reference signal is lower than a ninth threshold value, or in the case that the BF detection is performed according to the signal performance of the second type of reference signal comprised in the first reference signal, and the signal measurement result or the function value of all the second type of reference signal is lower than a tenth threshold value, the terminal triggers or indicates the BF.

[0206] In some implementations, the BF detection according to the signal performance of the first type of reference signal or the second type of reference signal comprised in the first reference signal in the manner 22 can at least include: in the case that the BF detection is performed according to the signal performance of the first type of reference signal comprised in the first reference signal, and the signal measurement result or the function value of at least one of the first type of reference signal is higher than an eleventh threshold value, or in the case that the BF detection is performed according to the signal performance of the second type of reference signal comprised in the first reference signal, and the signal measurement result or the function value of at least one of the second type of reference signal is higher than a twelfth threshold value, the terminal performs a fourth operation; wherein the fourth operation can include but is not limited to at least one of the following operations 41-Operation: 4.

[0207] Operation 41: does not indicate or trigger the BF.

[0208] Operation 42: cancels the BF.

[0209] Operation 43: resets the BF related timer or counter.

[0210] Operation 44: determines that the wireless link has been restored.

[0211] In some embodiments, the aforementioned BF detection provided in the aforementioned manner 11, manner 22 can be performed for the current one or more reference signals or bandwidth parts (bandwidth part, BWP) or beams or beam groups or beam patterns, etc. In addition, in the present embodiment, the first reference signal used for the BF detection corresponds to at least one beam group or beam pattern, which is not limited here.

[0212] In some embodiments, the aforementioned BF detection provided in Mode 11 and Mode 22 can also be performed per beam group or per beam pattern, e.g., when performing BF detection per beam group, the performance of both types of reference signals (e.g., the first type and the second type of reference signals) can be considered simultaneously as shown in Mode 21, or only one type of reference signals (e.g., the first type or the second type of reference signals) can be considered as shown in Mode 22, without limitation.

[0213] Of course, whether one type, two types or multiple types of signals are considered when performing BF detection as described above can be determined by protocol agreement, higher layer configuration, etc., or according to at least one of 61)-63) below.

[0214] 61) the type of reference signals included in the beam group or beam pattern.

[0215] For example, in the case where the beam group or beam pattern used for RLF detection includes the first type or the second type of reference signals, then the reference signals used for BF are the first type or the second type of reference signals; or in the case where the beam group or beam pattern used for RLF detection includes the first type and the second type of reference signals, then the reference signals used for BF include the first type and the second type of reference signals.

[0216] 62) the size of the measurement value of the reference signals.

[0217] For example, for the same type of reference signals, in the case where only the first type of reference signals is included in the type of reference signals whose measurement value is less than a certain threshold, then the reference signals used for BF are the first type of reference signals; or in the case where the first type and the second type of reference signals are included in the type of reference signals whose measurement value is less than a certain threshold, then the reference signals used for BF include the first type and the second type of reference signals.

[0218] Optionally, the measurement value can be characterized by RSRP, RSRQ, SIN, SINR, etc.

[0219] 63) the size of the PDCCH Block Error Rate.

[0220] For example, for the same type of reference signals, in the case where the PDCCH BLER is greater than a certain threshold, then the reference signals used for BF are the first type of reference signals, or in the case where the PDCCH BLER is greater than a certain threshold, then the reference signals used for BF include the first type and the second type of reference signals.

[0221] In this embodiment, the PDCCH BLER can be understood as a hypothesis PDCCH BLER or a predefined PDCCH BLER, etc.

[0222] In some embodiments, in the BF detection process, the reference signals of different types can also satisfy at least one of the following 71)-74).

[0223] 71) The reference signals of different signal types correspond to different weights.

[0224] The weight corresponding to the reference signal refers to the proportion of the measurement result of the reference signal in the plurality of measurement results used to judge the BF when the measurement result based on the reference signal is used for BF detection.

[0225] 72) The reference signals of different signal types correspond to different radio link detection windows or periods, that is, different signal types can use different radio link detection windows or periods for the same type of reference signal.

[0226] 73) When the radio link is in a specific state, the BF detection is performed using the first type of reference signal, wherein the specific state is an in-sync (IS) state or an out-of-sync state, that is, only in the in-sync state or the out-of-sync state, the measurement of the first type of reference signal is used or planned to be used for BF detection.

[0227] For example, when the radio link is in the in-sync state, the BF can be performed using the first type of reference signal, and when the radio link is in the out-of-sync state, the BF can be performed using the second type of reference signal, and vice versa.

[0228] 74) When the number of radio links in the out-of-sync state reaches an eighth threshold, the BF detection is performed using the first type of reference signal, that is, in the intermediate process.

[0229] For example, when the number of radio links in the out-of-sync state does not reach the eighth threshold, the BF can not be triggered, but the measurement of the first Lexi reference signal is activated, and when the number of radio links in the out-of-sync state reaches the eighth threshold, the BF based on the first type of reference signal is triggered.

[0230] In some embodiments, for the aforementioned BF detection, the second object (e.g., at least one of a signal quality threshold, a number threshold of beam failure instances, a BFD related timer or counter) configured therefor can consider multiple sets of factors, so as to flexibly control the BF conditions of the target user for different reference signals (or beams) or reference signal (or beam) types. Based on this, as one possible implementation, the determination manner of the second object for the BF detection can include, but is not limited to, at least one of the following 81) to 84).

[0231] 81) The determination is performed in granularity of each reference signal index or reference signal group index.

[0232] For example, for some beams or beam groups, if the beams are relatively narrow, the second object (e.g., a signal quality threshold, a number threshold of beam failure instances, or a BFD related timer or counter) can be set to be relatively large, so as to avoid too many users in the same narrow beam, and the capacity in such beam coverage will not be so large; vice versa.

[0233] 82) The determination is performed in granularity of the signal type of each reference signal.

[0234] For example, taking the number threshold of beam failure instances as an example, a number threshold of beam failure instances is defined for the second type of reference signal, and another number threshold of beam failure instances is defined for the first type of reference signal. Meanwhile, the number threshold of beam failure instances corresponding to the first type of reference signal can be set to be relatively small, so as to consider BF failure for the terminal in the edge cell in the case of very poor signal quality; and the number threshold of beam failure instances corresponding to the second type of reference signal can be set to be relatively large, so as to make most of the non-edge terminals have a high signal quality requirement, such as requiring to use the first type of reference signal or to determine BF as long as a certain high signal quality threshold is lower, so as to ensure the performance of the communication system.

[0235] 83) The determination is performed in granularity of each time unit. That is, the reference signals in different first time units are independently or differently configured with signal quality thresholds.

[0236] For example, assuming a time window of 180 ms, the reference signals in even time units are measured with reference to a first threshold, and the reference signals in other time units are measured with reference to a second threshold, where the first threshold and the second threshold can be the same or different.

[0237] 84) In the mTRP scenario, the second object (e.g., a signal quality threshold, a number threshold of beam failure instances, or a BFD related timer or counter) is independently configured for different TRPs, or the same second object is configured for different TRPs.

[0238] In this embodiment, a procedure for implementing BF detection based on reference signals of different signal types is provided, and it is determined when the corresponding reference signal can be used for BF detection, thereby avoiding wireless link detection errors.

[0239] It is worth noting that for the aforementioned RLF detection and BF detection, they can also be understood as a radio link quality measurement or detection process on a specific part of the band or band group or beam or beam group or specific reference signal (such as SSB) or specific reference signal group containing one or more reference signals or cell or cell group. That is, the detection-related solutions described in the foregoing S220 can also be applied to other radio link quality measurement or detection processes, which are not limited herein.

[0240] In some embodiments, for the case where the first reference signal is used for signal measurement, such as RLF detection, BF detection, etc., the terminal based on the reference signal (such as SSB, etc.) configuration will consider that there will be no downlink transmission on some time domain resources. When the terminal is configured with discontinuous reception (DRX), that is, the terminal does not continuously monitor the PDCCH, such as the terminal only receives the downlink signal (such as PDCCH) at some time. At this time, in order to ensure that the terminal can correctly receive the reference signal, the time domain resources corresponding to the reference signal and the time domain resources corresponding to the connected (C)-DRX need to be matched.

[0241] For example, in this embodiment, when measuring by using the first reference signal, the containing or contained relationship between the time domain resources corresponding to the first reference signal and the time domain resources corresponding to the C-DRX can be configured.

[0242] Optionally, the containing or contained relationship can include but is not limited to at least one of the following 91)-94).

[0243] 91) The relevant time of the C-DRX is located within the measurement time window of the first reference signal, thereby the reception of the first reference signal can be performed within the relevant time of the C-DRX, thereby ensuring the reception and measurement of the first reference signal.

[0244] Optionally, the relevant time of the C-DRX corresponds to at least one of the on duration, inactivity-timer, retransmission-timer, and active-time.

[0245] The on duration time can be understood as the time duration that the terminal waits to receive PDCCH after waking up. If the terminal successfully decodes PDCCH, the terminal stays awake and starts the inactivity timer.

[0246] The inactivity timer can be understood as the time duration that the terminal waits for a successful decoding of PDCCH, counting from the last successful decoding of PDCCH. If it fails, it can go back to sleep. The terminal shall restart the inactivity timer after a single successful decoding of PDCCH only for the first transmission (i.e. not for retransmissions).

[0247] The retransmission timer can be understood as the time duration that the terminal waits for a retransmission opportunity until a retransmission can be expected.

[0248] The active time can be understood as the total time duration that the terminal monitors PDCCH. It can include the “on duration time” of the DRX cycle, the time that the terminal performs continuous reception while the inactivity timer has not expired, and the time that the terminal performs continuous reception while waiting for a retransmission opportunity.

[0249] 92) The measurement time window of the first reference signal is located within the relevant time of the C-DRX. Thus, the reception of the first reference signal can be performed within the measurement time window, thereby ensuring the reception and measurement of the first reference signal.

[0250] 93) A specific overlap time is located within the measurement time window of the first reference signal, wherein the specific overlap time comprises an overlap time between the relevant time of the C-DRX and the relevant time of the cell DRX and / or the relevant time of the cell discontinuous transmission (DTX). Thus, the reception of the first reference signal can be performed within the specific overlap time, thereby ensuring the reception and measurement of the first reference signal.

[0251] The cell DRX can be understood as the DRX of the non-connected state, and the cell DTX can be understood as the DTX of the non-connected state. In this embodiment, similar to the relevant time of the C-DRX, the relevant time of the cell DTX or the cell DRX can also correspond to at least one of the on duration time, the inactivity timer, the retransmission timer, and the active time.

[0252] 94) The measurement time window of the first reference signal is located within the specific overlap time. Thus, the reception of the first reference signal can be performed within the measurement time window, thereby ensuring the reception and measurement of the first reference signal.

[0253] In some embodiments, for the C-DRX, the determination manner of the relevant information of the C-DRX can include but is not limited to at least one of the following 101)-103).

[0254] 101) determining in granularity of index of each reference signal or index of reference signal group, i.e. different reference signal index or reference signal group index configures independent or different C-DRX related information.

[0255] 102) determining in granularity of each signal type, i.e. different signal type configures independent or different C-DRX related information.

[0256] 103) determining in granularity of each time unit, i.e. independent or different C-DRX related information is configured in different time unit.

[0257] Wherein, for the aforementioned C-DRX related information, it can include but not limited to at least one of the following: on duration corresponding to the C-DRX, inactivity timer corresponding to the C-DRX, retransmission timer corresponding to the C-DRX, activation time, reference signal measurement window defined based on the C-DRX configuration.

[0258] In the embodiment, the reference signal measurement window defined based on the C-DRX configuration can be understood as a newly defined reference signal measurement window accompanying the C-DRX configuration, for example, as shown in FIG. 4, a reference signal measurement window is redefined in a cycle. The cycle is used to specify the periodic repetition of the on duration, and then there can be a period of inactivity.

[0259] Based on this, in some embodiments, the terminal measuring the first reference signal can at least include: measuring the first reference signal based on at least one of the following 111).

[0260] 111) the on duration corresponding to the C-DRX.

[0261] 112) the inactivity timer corresponding to the C-DRX.

[0262] 113) the retransmission timer corresponding to the C-DRX.

[0263] 114) the activation time corresponding to the C-DRX.

[0264] 115) the overlap time between the on duration corresponding to the C-DRX and the on duration corresponding to the cell DRX or the on duration corresponding to the cell DTX.

[0265] 116) the overlap time between the running time of the inactivity timer corresponding to the C-DRX and the running time of the inactivity timer corresponding to the cell DRX or the running time of the inactivity timer corresponding to the cell DTX.

[0266] 117) overlap time between running time of the retransmission timer corresponding to the C-DRX and running time of the retransmission timer corresponding to the cell DRX or running time of the retransmission timer corresponding to the cell DTX.

[0267] 118) overlap time between the activation time corresponding to the C-DRX and the on duration corresponding to the cell DRX or the activation time corresponding to the cell DTX.

[0268] 119) reference signal measurement window defined based on the C-DRX configuration.

[0269] In the embodiment, for the C-DRX characteristics of the connected state terminal, the association relationship between the reference signal configuration and the terminal DRX time is considered, so as to avoid the conflict between the C-DRX and the reference signal transmission time, and ensure the correct reception of the reference signal.
