Description

[0001] This application is a divisional application of the Chinese patent application with application number "202110363329.4", application date "April 2, 2021", and title "Channel transmission, receiving method, communication node and storage medium". Technical Field

[0002] The present application relates to a wireless communication network, for example, to a channel sending and receiving method, a communication node and a storage medium. Background Art

[0003] In the contention-based random access (CBRA) process, the terminal (User Equipment, UE) needs to send hybrid automatic repeat request acknowledgment (HARQ-ACK) information through the physical uplink control channel (PUCCH), and the transmission of PUCCH supports frequency hopping (Frequency Hopping) by default.

[0004] Terminals have different capabilities. For example, terminals used in NR systems (New Radio User Equipment, NR UE for short) usually have higher performance, while for application scenarios such as wearable devices, video surveillance, and industrial wireless sensors, terminals with simplified functions (RedCap UE for short) can meet the needs. Compared with NR UE, RedCap UE has weaker capabilities and supports smaller bandwidth and fewer antennas.

[0005] If the bandwidth of the initial uplink bandwidth part (Initial UpLink Bandwidth Part, referred to as initial UL BWP) configured by the network side exceeds the maximum working bandwidth supported by the terminal with weaker capabilities, the PUCCH resource position after frequency hopping will exceed the bandwidth range supported by such terminals, resulting in such terminals being unable to complete PUCCH transmission, and further causing the failure of the contention-based random access process. Therefore, the existing frequency hopping mechanism cannot guarantee that UEs with different capabilities can complete PUCCH transmission, making the reliability of the contention-based random access process low. Summary of the invention

[0006] The present application provides a channel sending and receiving method, a communication node and a storage medium to ensure that the UE completes the transmission of the PUCCH and improve the reliability of the contention-based random access process.

[0009] The corresponding PUCCH is sent according to the PUCCH frequency hopping pattern.

[0010] The embodiment of the present application also provides a channel receiving device, including:

[0011] Determine a PUCCH frequency hopping pattern, where the PUCCH frequency hopping pattern is one of preset frequency hopping patterns, and the preset frequency hopping pattern includes at least two frequency hopping patterns, wherein in the first frequency hopping pattern, the PUCCHs before and after the hopping occupy adjacent time domain symbols, and in the second frequency hopping pattern, there is a gap between the time domain symbols occupied by the PUCCHs before and after the hopping;

[0012] The corresponding PUCCH is received according to the PUCCH frequency hopping pattern.

[0031] The present application is described below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. It should also be noted that, for ease of description, only the parts related to the present application rather than all structures are shown in the accompanying drawings.

[0032] Figure 1 The flowchart of a channel transmission method provided in an embodiment is shown in FIG. 1 . The method can be applied to a sender of a PUCCH, such as a UE. Figure 1 As shown, the method provided in this embodiment includes step 110 and step 120.

[0033] In step 110, a physical uplink control channel PUCCH frequency hopping pattern is determined, and the PUCCH frequency hopping pattern is one of preset frequency hopping patterns, and the preset frequency hopping pattern includes at least two frequency hopping patterns, wherein in the first frequency hopping pattern, the PUCCH before and after the hopping occupies adjacent time domain symbols, and in the second frequency hopping pattern, there is a gap between the time domain symbols occupied by the PUCCH before and after the hopping.

[0034] In step 120, the corresponding PUCCH is sent according to the PUCCH frequency hopping pattern.

[0035] A channel sending method provided in an embodiment of the present application determines a PUCCH frequency hopping pattern from at least two frequency hopping patterns for PUCCH transmission, wherein a first frequency hopping pattern has no interval between the PUCCHs before and after the hopping, so that a UE with a stronger capability (NR UE) can quickly complete the hopping and sending of the PUCCH; a second frequency hopping pattern has an interval between the PUCCHs before and after the hopping, so that a UE with a weaker capability (RedCap UE) can use the interval to perform radio frequency adjustment to support the PUCCH resource position after the hopping, thereby configuring at least two frequency hopping patterns to ensure the reliability of PUCCH transmission by UEs with different capabilities and the contention-based random access process.

[0036] In one embodiment, step 110 includes:

[0037] According to the first signaling of the network side, the second frequency hopping pattern is used as the PUCCH frequency hopping pattern; or,

[0038] When a set condition is met, using a second frequency hopping pattern in the preset frequency hopping pattern as the PUCCH frequency hopping pattern;

[0039] The setting conditions include at least one of the following:

[0040] The bandwidth of the initial uplink bandwidth exceeds the maximum working bandwidth supported by the terminal;

[0041] The bandwidth of the initial uplink bandwidth exceeds the value configured on the network side;

[0042] The bandwidth of the initial upstream bandwidth portion exceeds the default value.

[0043] In this embodiment, the UE may use a frequency hopping pattern as a PUCCH frequency hopping pattern for sending a PUCCH according to the first signaling of the network side or according to a set condition. For example, the network side may instruct the NR UE to use the first frequency hopping pattern as the PUCCH frequency hopping pattern or instruct the RedCap UE to use the second frequency hopping pattern as the PUCCH frequency hopping pattern through the first signaling.

[0044] For RedCap UE, if the set conditions are met, the second frequency hopping pattern can be used as the PUCCH frequency hopping pattern, otherwise, the first frequency hopping pattern is used as the PUCCH frequency hopping pattern. The set conditions mean that the bandwidth of the initial uplink bandwidth configured by the network side is large and exceeds the bandwidth range supported by the RedCap UE in the working frequency band. Frequency hopping within such a large bandwidth range will cause the RedCap UE to fail to send PUCCH. In this case, the second frequency hopping pattern is used as the PUCCH frequency hopping pattern of the RedCap UE, and an interval is reserved during the frequency hopping process, thereby providing a guarantee for the frequency hopping transmission of the RedCap UE.

[0045] In one embodiment, step 110 includes: including one of the following:

[0046] Determine a PUCCH frequency hopping pattern according to the PUCCH format and the number of time domain symbols occupied by the PUCCH;

[0047] Determine a PUCCH frequency hopping pattern according to the PUCCH format, the number of time domain symbols occupied by the PUCCH before hopping, and the number of time domain symbols occupied by the PUCCH after hopping;

[0048] Determine a PUCCH frequency hopping pattern according to a PUCCH format, a number of time domain symbols occupied by the PUCCH, a number of time domain symbols occupied by the PUCCH before hopping, and a number of time domain symbols occupied by the PUCCH after hopping;

[0049] Determine a PUCCH frequency hopping pattern according to a PUCCH format;

[0050] Determine a PUCCH frequency hopping pattern according to the number of time domain symbols occupied by the PUCCH;

[0051] The PUCCH frequency hopping pattern is determined according to the second signaling on the network side.

[0052] In this embodiment, the UE may determine the PUCCH frequency hopping pattern according to one or more of the PUCCH format, the number of time domain symbols occupied by the PUCCH, the number of time domain symbols occupied by the PUCCH before hopping, the number of time domain symbols occupied by the PUCCH after hopping, and the second signaling on the network side. Among them, the second signaling may include one or more parameters that the UE may determine according to the PUCCH format, the number of time domain symbols occupied by the PUCCH, the number of time domain symbols occupied by the PUCCH before hopping, and the number of time domain symbols occupied by the PUCCH after hopping. In one embodiment, the time domain symbols occupied by the PUCCH before and / or after hopping in the second frequency hopping pattern are determined according to the interval.

[0053] In one embodiment, the time domain length of the interval is an integer multiple of a time domain symbol, or an integer multiple of a time domain sampling interval, or an integer multiple of a time domain measurement unit.

[0054] Preferably, in the second frequency hopping pattern, the interval between the time domain symbols occupied by the PUCCH before and after the hopping is an integer number of time domain symbols.

[0055] In one embodiment, the second frequency hopping pattern satisfies: the second frequency hopping pattern and the first frequency hopping pattern are in one time slot; the time domain symbols occupied by the PUCCH before the hopping in the second frequency hopping pattern are different from those occupied by the PUCCH before the hopping in the first frequency hopping pattern; the time domain symbols occupied by the PUCCH after the hopping in the second frequency hopping pattern are the same as those occupied by the PUCCH after the hopping in the first frequency hopping pattern.

[0056] In this embodiment, two frequency hopping patterns are in one time slot, and the PUCCHs before the two frequency hopping patterns hop occupy different time domain symbols, and the PUCCH after hopping in the second frequency hopping pattern multiplexes the PUCCH after hopping in the first frequency hopping pattern. This situation is applicable to PUCCH format 0.

[0057] It should be noted that the PRB index occupied by the PUCCH in the frequency domain before and after the hopping can be determined according to the number of CCEs in the control resource set (CORESET), the index of the first CCE of the PDCCH, and the value of the PUCCH resource indication field given by the downlink control information (Downlink Control Information, DCI). In addition, the determined PRB indexes of the PUCCH before and after the hopping are expressed relative to the index of a reference PRB, for example, the starting PRB in the reference initial uplink bandwidth part.

[0058] Figure 2 FIG. 1 is a schematic diagram of two frequency hopping patterns of a PUCCH format of format 0 provided in an embodiment. Figure 2As shown, one time slot includes 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols, and one box represents one PRB. The box where the slash area is located represents the PUCCH of RedCap UE, and the box where the unfilled area is located represents the PUCCH of NR UE.

[0059] In the first frequency hopping pattern, OFDM symbol #12 in a time slot is used as the symbol of the PUCCH before hopping (First Hopping Symbol); symbol #13 in the time slot is used as the symbol of the PUCCH after hopping (Second Hopping Symbol), and there is no interval between the PUCCHs before and after the hopping (i.e., the RF adjustment interval, Radio Frequency returning).

[0060] In the second frequency hopping pattern, symbol #11 in the time slot is used as the symbol of the PUCCH before hopping; symbol #12 in the time slot is used as the interval; and symbol #13 is used as the symbol of the PUCCH after hopping.

[0061] Figure 2 In the example, one PRB on symbol #13 needs to support the simultaneous transmission of PUCCH of RedCap UE and NR UE, that is, the PUCCH after the two frequency hopping patterns hop share the same PRB. It should be noted that in the contention-based random access process, the network side (such as gNB) must identify the RedCap UE before sending the fourth message (referred to as Msg4, sent by the network side to the UE to solve the collision problem of the third message Msg3) to the UE, otherwise it is impossible to accurately find the symbol of the PUCCH before the hopping of the RedCap UE.

[0062] also, Figure 2 The second frequency hopping pattern shown in supports repeated transmission at a single time slot level.

[0063] In one embodiment, the second frequency hopping pattern satisfies: the time domain symbols occupied by the PUCCH before the hopping in the second frequency hopping pattern and the PUCCH before the hopping in the first frequency hopping pattern are the same and are located in the same time slot; the time domain symbols occupied by the PUCCH after the hopping in the second frequency hopping pattern and the PUCCH after the hopping in the first frequency hopping pattern are located in different time slots.

[0064] In this embodiment, the PUCCHs before the two hopping patterns are in the same time slot, and the PUCCH before the second hopping pattern is multiplexed with the PUCCH before the first hopping pattern; the PUCCHs after the two hopping patterns are in different time slots. This situation is applicable to PUCCH format 0.

[0065] Figure 3 FIG. 1 is a schematic diagram of two frequency hopping patterns when another PUCCH format is format 0 provided in an embodiment. Figure 3 As shown in the figure, one time slot includes 14 OFDM symbols, and one box represents one PRB. The box where the slash area is located represents the PUCCH of RedCap UE, and the box where the unfilled area is located represents the PUCCH of NR UE.

[0066] In the first frequency hopping pattern, symbol #12 in time slot 0 is used as the symbol of the PUCCH before the hopping; symbol #13 in the time slot is used as the symbol of the PUCCH after the hopping, and there is no interval between the PUCCHs before and after the hopping.

[0067] In the second frequency hopping pattern, symbol #12 in the time slot is used as the symbol of the PUCCH before hopping; symbol #13 in the time slot is used as the interval; and symbol #0 in time slot 1 is used as the symbol of the PUCCH after hopping.

[0068] Figure 3 In the example, one PRB on symbol #12 of time slot 0 needs to support the simultaneous transmission of PUCCH of RedCap UE and NR UE, that is, the PUCCH before the two hopping patterns hop share the same PRB. It should be noted that in the contention-based random access process, the network side must identify the RedCap UE before sending the fourth message to the UE, otherwise it will not be possible to accurately find the symbol of the PUCCH before the hopping of the RedCap UE.

[0069] also, Figure 3 The second frequency hopping pattern shown in supports repeated transmission at 2 time slot levels.

[0070] In one embodiment, the second frequency hopping pattern satisfies:

[0071] The time domain symbol occupied by the PUCCH before hopping in the second frequency hopping pattern has the same index as the time domain symbol occupied by the PUCCH before or after hopping in the first frequency hopping pattern, and is located in the same time slot;

[0072] The time domain symbols occupied by the PUCCH after the hopping in the second frequency hopping pattern have the same index as the time domain symbols occupied by the PUCCH before or after the hopping in the first frequency hopping pattern, and are located in different time slots.

[0073] In this embodiment, the PUCCHs before the two frequency hopping patterns are in the same time slot; the PUCCHs after the two frequency hopping patterns are in different time slots. In addition, the PUCCH before the second frequency hopping pattern can reuse the PUCCH before the first frequency hopping pattern, or reuse the PUCCH after the first frequency hopping pattern; the PUCCH after the second frequency hopping pattern can reuse the PUCCH before the first frequency hopping pattern, or reuse the PUCCH after the first frequency hopping pattern; this situation is applicable to PUCCH format 0.

[0074] Figure 4 FIG. 1 is a schematic diagram of two frequency hopping patterns when another PUCCH format is format 0 provided in an embodiment. Figure 4 As shown in the figure, one time slot includes 14 OFDM symbols, and one box represents one PRB. The box where the slash area is located represents the PUCCH of RedCap UE, and the box where the unfilled area is located represents the PUCCH of NR UE.

[0075] In the first frequency hopping pattern, symbol #12 in time slot 0 and time slot 1 is used as the symbol of PUCCH before hopping; symbol #13 in time slot 0 and time slot 1 is used as the symbol of PUCCH after hopping, and there is no interval between PUCCH before and after hopping in each time slot.

[0076] In the second frequency hopping pattern, symbol #12 or symbol #13 in time slot 0 is used ( Figure 4 Symbol #12 is used as an example in the example) as the PUCCH symbol before the hopping; symbol #12 or symbol #13 in time slot 1 is used ( Figure 4 Symbol #13 is used as an example in the figure) as the symbol of the PUCCH after the jump; the symbols between the symbols occupied by the PUCCH before and after the RedCap jump are used as intervals.

[0077] On this basis, the PUCCHs before the two hopping patterns share the same PRB, and the PUCCHs after the hopping share the same PRB. It should be noted that in the contention-based random access process, the network side must identify the RedCap UE before sending the fourth message to the UE, otherwise it is impossible to accurately find the symbol of the PUCCH before the hopping of the RedCap UE.

[0078] also, Figure 4 The second frequency hopping pattern shown in supports repeated transmission at 2 time slot levels.

[0079] In one embodiment, the time domain symbol occupied by the PUCCH after the hopping in the second frequency hopping pattern is located in the next time slot of the time domain symbol occupied by the PUCCH before the hopping.

[0080] In this embodiment, the time domain symbols occupied by the PUCCH before and after the hopping in the second frequency hopping pattern are located in adjacent time slots, such as Figure 3 or Figure 4 as shown to increase the appropriate time domain interval.

[0081] In one embodiment, the PUCCH frequency hopping pattern is the second frequency hopping pattern;

[0082] Step 120 includes:

[0083] In the case where PUCCH supports repeated transmission, one repeated transmission occupies one time slot, and the corresponding PUCCH (for example Figure 2 The second frequency hopping pattern shown); or,

[0084] In the case where PUCCH supports repeated transmission, one repeated transmission occupies two time slots, and the corresponding PUCCH (for example Figure 3 and Figure 4 The second frequency hopping pattern shown).

[0085] In one embodiment, PUCCH satisfies at least one of the following (e.g. Figure 2-4 shown):

[0086] The PUCCH format is format 0;

[0087] The number of time domain symbols occupied by PUCCH is 2;

[0088] The number of time domain symbols occupied by the PUCCH before the hopping is 1, and the number of time domain symbols occupied by the PUCCH after the hopping is 1.

[0089] In one embodiment, the time domain symbols occupied by the PUCCH include a first type of time domain symbols used to send a reference signal (RS) and a second type of time domain symbols used to carry uplink control information;

[0090] The second frequency hopping pattern satisfies:

[0091] In one time slot, the first type of time domain symbols occupied by the PUCCH before hopping in the second frequency hopping pattern are the same as the first type of time domain symbols occupied by the PUCCH before hopping in the first frequency hopping pattern, and the second type of time domain symbols occupied by the PUCCH before hopping in the second frequency hopping pattern are different from the second type of time domain symbols occupied by the PUCCH before hopping in the first frequency hopping pattern;

[0092] The first type of time domain symbols occupied by the PUCCH after hopping in the second frequency hopping pattern are the same as the first type of time domain symbols occupied by the PUCCH after hopping in the first frequency hopping pattern, and the second type of time domain symbols occupied by the PUCCH after hopping in the second frequency hopping pattern are the same as the second type of time domain symbols occupied by the PUCCH after hopping in the first frequency hopping pattern.

Figure 5 As shown in the figure, one time slot includes 14 OFDM symbols, and one box represents one PRB. The box where the dotted area is located represents the PUCCH used by the NR UE to send RS, and the box where the unfilled area is located represents the PUCCH used by the NR UE to carry uplink control information. This situation applies to PUCCH format 1.

[0094] For the first frequency hopping pattern, symbols #10 and #11 in one time slot are used as PUCCH symbols before hopping, and symbols #12 and #13 in the time slot are used as PUCCH symbols after hopping, wherein RS is sent on symbols #10 and #12.

This situation applies to PUCCH format 1.

[0096] For the second frequency hopping pattern, symbols #9 and #10 in one time slot are used as the symbols of the PUCCH before the RedCap hopping, wherein RS is transmitted on symbol #10, and the PUCCH transmitting RS on symbol #10 shares the PUCCH transmitting RS before the hopping in the first frequency hopping pattern. The symbols of the PUCCH after the RedCap hopping share symbols #12 and #13 with the PUCCH after the hopping in the first frequency hopping pattern; wherein RS is transmitted on symbol #12. In this time slot, symbol #11 is used as an interval.

In this time slot, symbols #X+4 to #11 are intervals.

[0105] It should be noted that symbol #X can be selected according to the interval between PUCCHs before and after the RedCap UE jumps, and the quantization unit of the interval is the time domain length of the OFDM symbol, that is, the interval includes an integer number of OFDM symbols.

[0106] In one embodiment, PUCCH satisfies at least one of the following (e.g. Figure 5-7 shown):

[0107] The PUCCH format is format 1;

[0108] The number of time domain symbols occupied by PUCCH is 4;

[0356] The channel receiving device proposed in this embodiment and the channel receiving method proposed in the above embodiment belong to the same inventive concept. The technical details not fully described in this embodiment can be referred to any of the above embodiments, and this embodiment has the same beneficial effects as executing the channel sending method.

[0357] In addition, according to the current wireless communication standard, UE can use discontinuous reception (DRX) in idle mode to reduce power consumption. The discontinuous reception of UE in idle mode mainly monitors the paging channel and the broadcast channel. As long as a fixed cycle is defined, the purpose of discontinuous reception can be achieved. The description of the DRX cycle for currently determining paging is as follows: if the upper layer configures a UE-specific extended DRX value of 512 radio frames, the DRX cycle of the UE is 512. Otherwise, the DRX cycle of the UE is determined by the shortest of the UE-specific DRX value (if assigned by the upper layer) and the default DRX value broadcast in the system information. If the upper layer does not configure a UE-specific DRX, the default value is applied. In the connection inactive RRC_INACTIVE state, if the upper layer does not configure extended DRX, the DRX cycle of the UE is determined by the shortest of the radio access network RAN ​​paging cycle, the UE-specific paging cycle (if assigned by the upper layer) and the default paging cycle. Otherwise, when extended DRX is configured by upper layers, in the connected inactive RRC_INACTIVE state, the DRX cycle of the UE is determined by the shortest of the RAN paging cycle, the UE-specific paging cycle (if assigned by upper layers) and the default paging cycle during the paging time window (PTW), and the RAN paging cycle outside the PTW.

[0358] Since the UE needs to monitor the core network (CN) paging in both idle mode and connection inactive RRC_INACTIVE state, how to ensure that the group wake-up signal (GWUS) resource selection, paging subframe, and paging narrowband selected by the base station and the UE for CN paging are consistent requires further analysis.

[0359] Fig.15 A schematic diagram of a wireless communication system provided by an embodiment. Fig.15An example of a wireless communication system (e.g., based on LTE-evolved Machine Type Communication (eMTC), long term evolution (LTE), 5G or NR cellular network) including a base station (BS) 120 and one or more user equipments (UEs) 111, 112 and 113 is shown. In some embodiments, uplink transmissions (131, 132, 133) may include uplink control information (UCI), higher layer signaling (e.g., UE assistance information or UE capabilities), or uplink information. In some embodiments, downlink transmissions (141, 142, 143) may include downlink control information (DCI) or higher layer signaling or downlink information. The UE may be, for example, a smartphone, a tablet, a mobile computer, a machine-to-machine (M2M) device, a terminal, a mobile device, an Internet of Things (IoT) device, etc.

[0360] The parameter determination device provided in this embodiment is used for the parameter determination method of the embodiment of the present application. The implementation principle and technical effect of the parameter determination device provided in this embodiment are similar to those of the parameter determination method of the embodiment of the present application, and will not be repeated here.

[0361] In an exemplary implementation, GWUS resource selection, paging subframe and paging narrowband selection depend on the DRX cycle. Since the UE needs to monitor CN paging in both idle mode and RRC_INACTIVE state, in order to ensure that the GWUS resource selection, paging subframe and paging narrowband selected by the base station and the UE for CN paging are consistent, the following implementation methods need to be adopted.

[0362] In an exemplary implementation, for a UE in RRC_INACTIVE state, in a scenario where CN paging and RAN paging need to be monitored simultaneously, the DRX cycle is equal to the DRX cycle in idle mode; otherwise, the DRX cycle is equal to the RAN paging cycle. A specific method for determining the DRX cycle in the RRC_INACTIVE state includes at least one of the following:

[0363] When the core network non-access stratum (NAS) is not configured with paging extended DRX, the DRX cycle is determined by the shortest cycle of the UE-specific paging cycle (if the upper layer configures the UE-specific paging cycle) and the default paging cycle.

[0364] When NAS configures paging extended DRX but does not include a paging time window (PTW), the DRX cycle is a paging eDRX cycle. For example, in eMTC, when paging extended DRX=512 radio frames, the DRX cycle is 512 radio frames.

[0365] When NAS configures paging extended DRX and includes PTW, the DRX cycle within the PTW window is determined by the shortest cycle of the UE-specific paging cycle (if the upper layer configures the UE-specific paging cycle) and the default paging cycle, while the DRX cycle outside the PTW window is determined by the RAN paging cycle.

[0366] In an exemplary implementation, for a UE in RRC_INACTIVE state, in a scenario where it is necessary to monitor CN paging and RAN paging at the same time, when calculating the paging radio frame, the DRX cycle is determined by the shortest cycle of the RAN paging cycle and the DRX cycle in idle mode. When calculating other radio resources such as paging subframes, paging narrowband, GWUS resources, etc., the DRX cycle is determined by the DRX cycle in idle mode. For a UE in RRC_INACTIVE state, in a scenario where it is not necessary to monitor RAN paging, the DRX cycle is determined by the RAN paging cycle. The specific method for determining the DRX cycle in the RRC_INACTIVE state includes at least one of the following:

[0367] For paging radio frame calculation: When NAS does not configure paging extended DRX, the DRX cycle is determined by the shortest cycle among the RAN paging cycle, the UE-specific paging cycle (if assigned by upper layers), and the default paging cycle. When paging extended DRX is configured by NAS, but PTW is not included, the DRX cycle is determined by the shortest cycle among the RAN paging cycle and the paging extended DRX cycle, for example, in eMTC, when the paging extended DRX cycle is determined by the shortest cycle among the RAN paging cycle and the cycle of 512 radio frames. When paging extended DRX is configured by NAS and PTW is included, the DRX cycle within the PTW window is determined by the shortest cycle among the UE-specific paging cycle (if the upper layer configures the UE-specific paging cycle) and the default paging cycle, and outside the PTW window the DRX cycle is determined by the RAN paging cycle.

[0368] For other paging resource calculations (e.g., paging subframe calculation, paging narrowband calculation, GWUS resource selection): When NAS does not configure paging extended DRX, the DRX cycle is determined by the shortest cycle of the UE-specific paging cycle (if the upper layer configures the UE-specific paging cycle) and the default paging cycle. When paging extended DRX is configured by NAS but does not include PTW, the DRX cycle is determined by the paging extended DRX cycle. For example, in eMTC, when paging extended DRX = 512 radio frames, the DRX cycle is 512 radio frames. When paging extended DRX is configured by NAS and includes PTW, the DRX cycle within the PTW window is determined by the shortest cycle of the UE-specific paging cycle (if the upper layer configures the UE-specific paging cycle) and the default paging cycle, while the DRX cycle outside the PTW window is determined by the RAN paging cycle.

[0369] In an exemplary embodiment, the DRX cycle of CN paging is determined by the shortest cycle of the UE-specific paging cycle (if the upper layer configures the UE-specific paging cycle) and the default paging cycle. The DRX cycle of RAN paging is determined by the RAN paging cycle. When the UE monitors CN paging, the paging resources are calculated using the DRX cycle of CN paging; when the UE monitors RAN paging, the paging resources are calculated using the DRX cycle of RAN paging; when the UE monitors CN paging and RAN paging at the same time, both resources are monitored simultaneously.

[0370] In an exemplary embodiment, the UE monitors CN paging in the RRC_INACTIVE state using the following strategy: When NAS does not configure paging extended DRX, the DRX cycle is determined by the shortest cycle among the RAN paging cycle, the UE-specific paging cycle (if assigned by the upper layer) and the default paging cycle. When NAS configures paging extended DRX but does not include PTW, the DRX cycle is determined by the shortest cycle among the RAN paging cycle and the paging extended DRX cycle length. For example, in eMTC, when the paging extended DRX cycle is determined by the shortest cycle among the RAN paging cycle and the cycle of 512 radio frames. When paging extended DRX is configured by NAS and includes PTW, the DRX cycle within the PTW window is determined by the shortest cycle among the UE-specific paging cycle (if the upper layer configures the UE-specific paging cycle) and the default paging cycle, and the DRX cycle outside the PTW window is determined by the RAN paging cycle. When the UE monitors CN paging and RAN paging at the same time, the base station sends paging simultaneously in the following two ways:

[0371] Mode 1: When NAS does not configure paging extended DRX, the DRX cycle is determined by the shortest cycle among the RAN paging cycle, the UE-specific paging cycle (if allocated by the upper layer) and the default paging cycle. When NAS configures paging extended DRX, but does not include PTW, the DRX cycle is determined by the shortest cycle among the RAN paging cycle and the paging extended DRX cycle length. For example, in eMTC, when the paging extended DRX cycle is determined by the RAN paging cycle and the shortest cycle with a cycle of 512 radio frames. When paging extended DRX is configured by NAS and includes PTW, the DRX cycle within the PTW window is determined by the shortest cycle among the RAN paging cycle, the UE-specific paging cycle (if allocated by the upper layer) and the default paging cycle. Outside the PTW window, the DRX cycle is determined by the RAN paging cycle.

[0372] Method 2: When NAS does not configure paging extended DRX, the DRX cycle is determined by the shortest cycle of the UE-specific paging cycle (if the upper layer configures the UE-specific paging cycle) and the default paging cycle. When paging extended DRX is configured by NAS but does not include PTW, the DRX cycle is determined by the paging extended DRX cycle. For example, in eMTC, when paging extended DRX = 512 radio frames, the DRX cycle is 512 radio frames. When NAS configures paging extended DRX and includes PTW, the DRX cycle within the PTW window is determined by the shortest cycle of the UE-specific paging cycle (if allocated by the upper layer) and the default paging cycle. Outside the PTW window, the DRX cycle is determined by the RAN paging cycle.

[0373] In an exemplary implementation, it is ensured through configuration that the RAN paging cycle is greater than or equal to the shortest cycle of the UE-specific paging cycle (if the upper layer configures the UE-specific paging cycle) and the default paging cycle.

[0374] In an exemplary implementation, configuration is performed to ensure that the number of paging occasions that the base station does not configure in a cycle is 4T or 2T.
