[0009] Carrier access using at least one SCell operating in an unlicensed frequency band Aggregation is also known as License Assisted Access (LAA). In LAA, the set of serving cells configured for a UE is the LAA SCell It operates in unlicensed spectrum according to frame structure type 3, sometimes referred to as Typically, the LAA SCell is , it may operate as a standard SCell.

[0010] The LAA eNB and UE listen before transmitting on the LAA SCell. When LBT is performed, the transmitter May listen / sense the channel to determine if it is idle or busy. If the channel is determined to be free, the transmitter may transmit; otherwise, If the LAA eNB does not have an LAA channel, it may not perform the transmission. If channel access signals of other technologies are used for access purposes, the maximum energy may continue to meet the energy detection threshold requirements.

[0011] LTE frame structure type 3 is an LAA with only a normal cyclic prefix. May be applied to secondary cell operation. Each radio frame is f =307200 T s = 10 ms long and numbered from 0 to 19, slot =15 360 T s A subframe may consist of 20 slots of 0.5 ms each. Subframe i is defined as two consecutive slots, i and 2i+1. This may be the case.

[0012] 10 subframes within a radio frame are available for downlink or uplink transmission A downlink transmission may occupy one or more consecutive subframes. For example, a subframe may start anywhere in the subframe and end in the last subframe. The uplink transmission may be completed completely or may continue with one of the DwPTS. or occupies several consecutive subframes.

[0013] The UE may use RRC_IDLE and RRC_INACTIV to reduce power consumption. In the E state, discontinuous reception (DRX) may be used. The UE receives one page per DRX cycle. The PO is the set of PDCCH monitoring occasions. and paging downlink control information (DCI) may be transmitted. It consists of several time slots (e.g., subframes or OFDM symbols) A paging frame (PF) is a radio frame that can contain one or more It may contain a number of POs or the start of a PO.

[0014] In multi-beam operation, the length of one PO is the period of one beam sweep. and the UE determines whether the same paging message is It can be assumed that the paging message is repeated in all beams. The selection of the beam for transmission may depend on the UE implementation. The message is the same for both RAN initiated and CN initiated paging. It may also be the case.

[0015] Upon receiving the RAN paging, the UE shall initiate the RRC connection resumption procedure. If the UE receives a CN initiated paging while in RRC_INACTIVE state, In this case, the UE may transition to RRC_IDLE and may notify the NAS.

[0016] The PF and PO may be determined by the following formula: The SFN of the PF is (SFN+PF_o ffset)modT = (TdivN) * (UE_IDmodN) stomach.

[0017] Index indicating the start of a set of PDCCH monitoring occasions for paging DCI (i_s) is determined by i_s=floor(UE_ID / N)modNs. stomach.

[0018] The PDCCH monitoring occasion for paging is paging-S, if configured. searchSpace and firstPDCCH-MonitoringOccasi Otherwise, PDCCH monitoring for paging may be determined according to onOfPO. The occasion may be determined according to the default association (i.e., paging The PDCCH monitoring occasion for RMSI may be the same as that for RMSI.

[0019] For default associations, Ns can be either 1 or 2. Ns=1 If Ns=2, there can be only one PO starting in the PF. , the first half frame (i_s=0) of the PF, or the second half frame (i_s =1).

[0020] In the case of a non-default association (i.e., when paging-SearchSpace is used) If the UE is used, the first PO may start within the PF (i_s+1)th PO. PDCCH monitoring for paging that does not overlap with UL symbols The number of PDCCH monitoring occasions for paging starts from zero to the first PDCCH monitoring occasion for paging in the PF. The PDCCHs may be numbered sequentially from the first PDCCH-MonitoringOccas If ionOfPO exists, the (i_s+1)th PO is the firstPDCCH -PDCCH monitoring occasion indicated by MonitoringOccasionOfPO Occasion (i.e., firstPDCCH-MonitoringOccasionO "S" consecutive page counts starting from the (i_s+1)th value of the fPO parameter otherwise, (i_s+1 The (i_s*S)th PO starts from the (i_s*S)th PDCCH monitoring occasion for paging. A set of "S" consecutive PDCCH monitoring occasions for paging, starting with In this case, "S" is the ssb- The number of SSBs actually transmitted is determined according to PositionsInBurst. The K-th PDCCH monitoring occasion for paging in a PO may be transmitted as the K-th PDCCH monitoring occasion. It may be compatible with SSB.

[0021] The following parameters may be used in the calculation of PF and i_s above: (1) T: UE DRX cycle (configured by RRC or higher layers and defaults to If the global DRX value is broadcast in the system information, T is the maximum of the UE-specific DRX values. The UE-specific DRX value may be determined by the lowest value configured by RRC or higher layers. If not, default values ​​may be applied) (2) Total number of paging frames in N:T (3) Ns: Number of paging occasions between PFs (4) PF_offset: Offset used in PF determination (5)UE_ID:5G-S-TMSImod1024 Parameters N, Ns, first-PDCCH-MonitoringOccasion OfPO, PF_offset and the default DRX cycle length are specified in SIB1. If the UE does not have 5G-S-TMSI, for example, If E is not yet registered with the network, the UE defaults to The identity UE_ID=0 and the above i_s formula may be used. The 5G-S-TMSI is , may be a bit string of 48 bits. The 5G-S-TMSI in the above formula is , may be interpreted in binary terms, with the most significant bit meaning

[0024] Table 2 below shows the DCI format with CRC scrambled by the P-RNTI. Indicates the information that may be transmitted by bit 1_0.

[0025] [Table 2]

[0026] With Bandwidth Adaptation (BA), the UE's receiving and transmitting bandwidth is typically adjusted to match the cell's bandwidth. They do not have to be the same size and may be adjusted, the width may be adjusted (e.g. The position may be instructed to change (to shrink during the period and save power), may be moved within the frequency domain (e.g., to increase scheduling flexibility); The subcarrier spacing may also be varied (e.g., to accommodate different services). A subset of the total cell bandwidth of a cell is called a Bandwidth Part (BWP). The BA may configure the UE with a BWP and determine which of the configured BWPs This can be achieved by informing the UE whether it is currently active.

[0027] FIG. 1 shows an example of a BA 100. In the example of FIG. 1, Three different BWPs, namely BWP1110, BWP2111, and BWP3 112 is shown. The BWP is 40 MHz wide and 15 kHz wide. subcarrier spacing, BWP2111 has 10MHz width and 15kHz subcarrier spacing. The BWP3112 has a 20 MHz width and a 60 kHz subcarrier spacing. The interval may be set to be equal to or greater than the predetermined interval.

[0028] A serving cell may consist of up to four BWPs, usually In an active serving cell, there is one active BWP at any point in time. BWP switching in the serving cell simultaneously activates the inactive BWP. It is used to activate an active BWP and deactivate an active BWP, and This may be controlled by the PDCCH indicating a block assignment or an uplink grant. Depending on the addition of SpCell (special cell) or activation of SCell One BWP receives a PDCCH indicating a downlink assignment or an uplink grant. The serving cell may be initially activated without first receiving the BWP may be indicated by RRC or PDCCH. In some bands, the DL BWP may be paired with a UL BWP, and BWP switching may be common to both UL and DL.

[0029] The embodiments described herein address some of the problems with conventional paging procedures. In NR, the UE monitors one PO per DRX cycle, and the PO is Each is a specific location within a paging frame (PF) in which a paging DCI may be transmitted. A PDCC corresponding to a fixed time instance (e.g., one or more OFDM symbols) In NR-U, the gNB performs DL transmission. Before implementing this, it may prevent the gNB from transmitting paging DCI during the PO. It may be necessary to perform LBT, which will cause the UE to try to page again. This results in the gNB having to wait for an entire DRX cycle before This may be the case, for example, for mobile termination for low system access latency services. (MT) when paging the UE for call establishment or when using a public alert system (P This may not be acceptable in some scenarios, such as when sending a WS) indication. Furthermore, NR allows for very quick transition of a UE from, for example, a low power state to a fully connected state. We propose the RRC_INACTIVE state to enable efficient transition. In NR-U, the paging procedure may be excessively affected by LBT. Therefore, the benefits of this condition may be lost. To ensure that the UE is paged reliably, NR-U paging The procedure needs to be expanded.

[0030] The embodiments described herein include the following solutions to the above problems. (1) For example, paging is performed using multiple POs during the following DRX cycle: How to do it. A method in which a UE monitors multiple POs during a DRX cycle. In this case, the POs to be monitored are: They may be multiplexed in the time and / or frequency domain. DRX size from one or more Paging-SearchSpace fields A method by which the UE selects the PO to monitor during a call. During a DRX cycle, one or more groups of PDCCH monitoring occasions How the UE selects which POs to monitor. The UE selects a PO to monitor during a DRX cycle from among POs associated with multiple PFs. How to choose. Based on a set of configured rules, the UE decides the next PO to monitor in a DRX cycle. How to determine. A method by which the UE monitors POs configured among multiple BWPs / subbands. The UE determines when the next PO configured in the DRX cycle needs to be monitored. How is this determined? (2) For example, a method of performing paging using the following paging window: How to define flexible starting points between POs. (3) Paging using POs with multiple sweeps / repetitions, e.g., How to implement this. The PO definition, where PO is defined as a set of consecutive PDCCH monitoring occasions, is May be used for transmission of paging DCI with multiple sweeps / repetitions . (4) For example, the DL channel access indication for paging is How to gunnerize. Signaling DL channel access indication via paging DCI How to do it. (5) A method of performing paging using dynamic DRX, for example, as follows: The UE detects that the gNB was / was able to acquire the channel during the PO How to dynamically adapt the DRX cycle when

FIG. 2 shows multiple POs 210 multiplexed in the time domain 202 and frequency domain 201. As shown in the example in Figure 2, to improve the robustness of the paging procedure, the UE , one or more of the POs 210 may be monitored during the DRX cycle, where the monitoring The one or more POs 210 to be monitored may be in the time domain 202 and / or frequency domain. The P to be monitored during the DRX cycle may be multiplexed in several fields 201. The number of O210s is determined by higher layers using broadcast or dedicated signaling. It may be pre-configured or configured and may be configured with, for example, service type, system access The required bandwidth may be determined by access latency requirements, power consumption requirements, etc.

[0032] For example, the PCCH included in the DownlinkConfigCommonSIB IE The -Config field specifies the parameters, e.g., that are to be monitored during the DRX cycle. It is used to signal Nm, which is used to configure the number of POs that will be For illustrative purposes, the parameter Nm may be set to a value equal to 1, 2, 4, or 8. The following scenarios are considered here: The PCCH-Config field may be signaled using the PCCH-Config field defined as follows: In this example, if the parameter Nm is not explicitly signaled, it has a default value of 1. Extensions to other parameters signaled via IEs, e.g. For example, support for additional SCS, Ns values, N values, PF offset values, etc. is shown below.

[0058] The UE may be configured to monitor multiple POs during a DRX cycle, where: A monitored PO may be associated with multiple groups of PDCCH monitoring occasions. In one embodiment, the PO to monitor is determined by the formula (SFN+PF_offset) mod T=(T divN)*(UE_IDmodN) to the PF along with the SFN, which may be determined by PDCCH monitoring occasions for paging DCI within each group may be associated.

This is an example of a PO that is not listed, which may be combined with any of the embodiments described herein. Each PO in this example may be used for many PDCCH monitoring occasions.

[0064] [Table 9]

[0065] The UE may be configured to monitor multiple POs during a DRX cycle, where: A monitored PO may be associated with multiple PFs. In one aspect, the monitoring PO is , the formula(SFN+PF_offset m )modT=(TdivN)*(UE_IDmod N), where PF _offset m is the mth PO that contains one or more POs to monitor during the DRX cycle. The offsets associated with the PFs are the PDCCHs for paging DCI within each PF. The index (i_s) that indicates the start of the set of monitoring occasions is i_s=floor It may be determined by (UE_ID / N) mod Ns.

[0066] The set of PF_offsets used is determined by broadcast or dedicated signaling. It may be configured by higher layers using a PF-associated protocol. For example, it may be associated with up to four PFs. In order to enable the UE to monitor the received PO, the The nAndPagingFrameOffset field contained in the It is okay to do so. nAndPagingFrameOffset CHOICE { oneT NULL, halfT SEQUENCE (SIZE (1..4)) OF INTEGER (0..1), quarterT SEQUENCE (SIZE (1..4)) OF INTEGER (0..3), oneEighthT SEQUENCE (SIZE (1..4)) OF INTEGER (0..7), oneSixteenthT SEQUENCE (SIZE (1..4)) OF INTEGER (0..15) }

[0067] FIG. 11A is an example 1100 of continuous PF monitoring according to one embodiment, which is It may be used in combination with any of the embodiments described herein. An example is each PF and its offset, i.e., PF 1101 and PF_Offset11 111, PF 1102 and PF_Offset21112, PF 1103 and PF_O ffset31113, and PF 1104 and PF_Offset41114. vinegar.

[0068] FIG. 11B is an example of non-continuous PF monitoring according to one embodiment, which is described herein. It may be used in combination with any of the described embodiments. Each PF and its offset, i.e., PF 1121 and PF_Offset11131 , PF 1122 and PF_Offset21132, PF 1123 and PF_Offs et31133, and PF 1124 and PF_Offset41134.

[0069] A rule-based method is used to determine the additional POs that may be monitored in a DRX cycle. The PF SFN corresponding to the first PO to monitor during the DRX cycle and the index i_s is given by the formula (SFN+PF_offset)modT=(Tdiv N)*(UE_IDmodN), and i_s=floor(UE_ID / N)modN s may be determined.

[0070] For example, if the gNB is unable to acquire a DL channel to transmit paging DCI during the PO, If the UE determines that an additional PO has been received, the UE may monitor for an additional PO during the DRX cycle. The UE shall use the method described herein to determine whether the DL channel has been acquired by the gNB. To determine whether the gNB was able to acquire the DL channel, Alternative methods that may be used for Indication (CAI) signal or any other signal transmitted by the gNB The use of a signal such as a signal from a sensor is also possible.

[0071] Aspects include a method for monitoring a next PO, wherein a UE monitors a next PO associated with a PF. In this case, the index of the next PO is i_s next_PO =i_s+1 where i_s<(Ns-1). In the scenario where the last PO associated with i_s is i_s=(Ns-1), the UE The UE may stop monitoring additional POs during the cycle. Alternatively, the UE may monitor the next PO. The PO associated with F may be monitored, where the SFN of the next PF is Nex t_PF =SFN PF It can be calculated as +floor(T / N).

[0072] The UE may monitor up to m POs during a DRX cycle, where m is the number of blocks. Pre-determined by each layer using broadcast or dedicated signaling, or The UE may be configured to monitor two or more POs in a PF. stomach.

[0073] To determine whether the gNB has acquired the DL channel, the UE may or any alternative method (e.g., discovery reference signal (DRS), CAI signal, or may use other signals, such as the detection of any other signal transmitted by the gNB. If the UE fails to detect the LBT within the PO, the UE will After the first PO where E fails LBT detection, it will For example, if the UE fails to detect LBT and the first PO After that, the UE successfully detects the LBT (i.e., there is no LBT failure) The UE monitors additional POs until it has monitored an additional k consecutive POs. Each additional PO that is monitored may belong to the same PF or a different PF. The parameter k is either configured for the UE by the gNB or set to a default value. The value of the parameter k may be determined, for example, by the service requirements and / or the UE power saving settings / It may be determined by preference.

[0074] Another alternative is that if the UE fails to detect the LBT within a PO, the UE may Within a circle, after the first PO where the UE fails LBT detection, a maximum of the next k additional POs Each additional monitored PO may be a subframe, slot, or mini-slot. Time is measured in units of seconds, and / or in units of seconds, which may be expressed in terms of symbols. For example, the UE may fail to detect LBT and the LBT may not be successful. After the first PO, the UE successfully detects the LBT (i.e., there is no LBT failure). The UE monitors additional POs until k is equal to k (or until the UE has monitored k consecutive POs). Each additional PO that is monitored may belong to the same PF or a different PF. The parameter k may be configured for the UE by the gNB or may be set to a fixed value. The value of the parameter k may be determined, for example, by the service requirements and / or the UE power saving settings / Similarly, the time interval between additional monitored POs may be determined by the gNB The additional monitored parameters may be configured for the UE by the The value of the time interval between POs depends, for example, on the service requirements and / or the UE power saving settings / selections. It may be determined by preference.

[0075] If the UE fails to detect LBT during a PDCCH monitoring opportunity within a PO, typically, the UE is the first PDCCH monitoring opportunity within a DRX cycle where the UE fails to detect LBT. , up to a maximum of the next k consecutive additional PDCCH monitoring opportunities. The UE fails LBT detection and after the first PDCCH opportunity where LBT is not successful, Either the LBT is successfully detected (i.e., equivalent to no LBT failure) or the UE is The UE continues to monitor the additional PDCCH monitoring opportunities until it has completed monitoring the additional k consecutive PDCCH monitoring opportunities. Additional consecutive PDCCH monitoring opportunities may occur in the same PO and / or the same They may belong to the same PF or to different POs and / or different PFs. Successive PDCCH opportunities are contiguous PDCCs in the time and / or frequency domain. The parameter k may be constructed as an H opportunity. The value of the parameter k may be configured for the UE or may be set to a default value. For example, it may be determined by service requirements and / or UE power saving settings / preferences.

[0076] If the UE fails to detect LBT during a PDCCH monitoring opportunity within a PO, typically, the UE is the first PDCCH monitoring opportunity within a DRX cycle where the UE fails to detect LBT. , up to a maximum of the next k PDCCH monitoring opportunities. Opportunities are determined in time by configurable time intervals and / or by configurable distances. In the frequency domain, the PDCCH monitoring opportunities may be spaced apart from each other. The distance is expressed in terms of subframes, slots, minislots and / or symbols. For example, if the UE fails to detect LBT and the first PD After a CCH monitoring opportunity, the UE successfully detects the LBT (i.e., there is no LBT failure). (equal to k) or until the UE has monitored k consecutive PDCCH monitoring opportunities. The UE may monitor the PDCCH. The monitored PDCCH monitoring occasions are the same PO and and / or may belong to the same PF, or to different POs and / or different PFs. Consecutive PDCCH opportunities are contiguous PDCCH opportunities in the time and / or frequency domain. In this case, the DRX cycle The distance between additional PDCCH monitoring opportunities is calculated as the difference between two additional PDCCH monitoring opportunities. The parameter k may be configured for the UE by the gNB or The value of the parameter k may be determined, for example, by service requirements and / or or may be determined by the UE power saving settings / preferences. The time interval between the The value of the time interval between additional monitored POs may depend on, for example, the service requirements and / or may be determined by the UE power saving settings / preferences.

[0077] A UE may monitor POs configured for multiple paging BWPs during a PO. In this case, the paging BWP allows the UE to monitor the PDCCH for paging. A common paging configuration may be used for each paging BWP. Alternatively, the configuration used for each paging BWP may be configured independently. In this case, the gNB may access two or more paging BWPs configured for a given UE during a PO. When gaining access, the gNB shall transmit the paging BWP to the UE for all paging BWPs to which it has gained access. Then, if the UE determines that the gNB has been accessed, The Paging BWP may attempt to receive the Paging DCI in any of the Paging BWPs that have In this case, the paging BWPs may be ranked and configured for a given UE during the PO. If a gNB gets access to two or more paging BWPs, the gNB shall The UE may then be paged using the paging BWP with the highest rank. ,the highest ranked page that the UE may determine that the gNB ,has access. The DL channel is divided into subbands. (UE may be configured for multiple paging subbands during a PO) The same procedure may be applied to the scenario where a PO is monitored.

[0078] The paging reliability is important when determining the number of POs that the UE may monitor per DRX cycle. There may be a trade-off between the performance and UE power consumption. Increasing the number of POs monitored per UE increases paging reliability but also increases UE power consumption. Generally, to optimize power consumption, the UE may choose to use DR under certain conditions. Only the next PO may be monitored for X cycles.

[0079] FIG. 12 illustrates a case where the next PO needs to be monitored according to one embodiment. 12 is a flow diagram of an example algorithm 1200, which is used in the implementations described herein. It may be used in combination with one of the following forms: D for transmission of paging DCI If the UE detects that the gNB has not obtained access to the L channel, the UE: During the DRX cycle, only the next PO may be monitored. In the example of FIG. i teeth, It may correspond to the i-th monitored PO in a DRX cycle, where i=1, i=1 is the first monitored PO in the DRX cycle, and i=2 is the second monitored PO in the DRX cycle. The i-th monitored PO in a DRX cycle is , when i=m, it does not necessarily correspond to the (i_sm+1)th PO. 2, m is set to 1 (step 1201). m Between C If an AI is detected (step 1202), the UE m Monitor (Step 12 05). Otherwise, the UE increments m (step 1203) and If ≦Nm, the process is repeated (step 1204).

[0080] If the PO includes multiple sweeps / iterations (e.g., an extended PO), the PD to be monitored The same mechanism can be applied to determine the number of CCH monitoring occasions.

[0081] In some configurations, all the packets that may need to be paged during a given PO There may be cases where the paging processing capacity is not sufficient to page the UE. In this case, it may be preferable for the UE to monitor the next PO during the DRX cycle. To enable such operation, in one aspect, the gNB may The paging throughput is sufficient to page all UEs that need to be paged. The next PO needs to be monitored. In one aspect, it may be necessary to be paged during the PO. indicates that the paging throughput was insufficient to page all UEs in the Therefore, the Paging DCI is used to handle situations such as exceeding the paging capacity as shown in Table 10 below. It may contain fields.

[0082] [Table 10]

[0083] FIG. 13 illustrates a case where the next PO needs to be monitored according to one embodiment. 13 is a flow diagram of an example algorithm 1300, which is used in the implementations described herein. The exemplary algorithm 1 of FIG. 300 indicates whether the paging capacity for the PO is exceeded during the DRX cycle. The UE considers the paging message when deciding whether it should monitor the next PO. Alternatively, this indicator may be checked to see if the E ID was included. The application is signaled via RRC using a field in the paging message. It may be included as PO i corresponds to the i-th monitored PO in the DRX cycle. where i=1 is the first monitored PO in the DRX cycle, and i =2 may be the second monitored PO in a DRX cycle, etc. The i-th monitored PO in the circle is always the (i_sm+1)th PO when i=m. It is also possible that m does not correspond to the number of the first pair. Referring to FIG. 13, m is set to 1 (step 1301). UE is PO m If the UE detects a CAI during (step 1302), The PO m If not, the UE increments m (step 1305). If m≦Nm, the process is repeated (step 1304). The UE may determine whether a paging DCI is received (step 1306 When a paging DCI is received, the UE checks whether its paging processing capability is exceeded. If the paging throughput is exceeded, the UE may determine whether to It may be determined whether the UE ID is present in the Giving message (step 130 8).

[0084] In NR, POs are fixed locations within a PF where paging DCI may be transmitted. May correspond to a time instance (e.g., one or more OFDM symbols) It may be a set of PDCCH monitoring occasions. First PDCCH monitoring in a PO If the gNB cannot acquire the DL channel before the start of the occasion, the channel is If O starts and then goes into idle state too soon (for example, a few symbols after PO starts), Even if the UE is not paged, the gNB must wait for all DRX cycles to elapse before attempting to page the UE again. The delay associated with paging a UE in NR-U may have to wait for a message. To reduce this, in one aspect, the paging monitoring window starts at a flexible starting point. The PO may be set so that:

[0085] FIG. 14 is a diagram of an exemplary paging monitoring window 1400 according to one embodiment. This may be used in combination with any of the embodiments described herein. The start point of the PO 1404, i.e., the PO offset 1403, is the paging monitor window. It is defined to occur at a flexible position (e.g., symbol / slot x) within the In this case, the maximum value of the PO offset 1403 is set to, for example, The fields contained in the IE may be signaled using broadcast or dedicated signaling. It may be defined or configured by higher layers.

[0086] In multi-beam operation, the length of one PO can be used for one or more beam sweeps. The UE may be configured to receive the same paging message for the duration of the sweep. It may be assumed that the ping pattern is repeated for all beams. Then, PO is given by S=( N SSB ×M) consecutive PDCCH monitoring occasions. , In this case, N SSB is a parameter in SystemInformationBlock1 Actual transmitted SSB determined according to ssb-PositionsInBurst , and M may be the number of sweeps used for paging transmission. The Kth paging PDCCH monitoring occasion in SSB ) No. It may correspond to SSB transmitted to the eye.

Figure 15 shows multiple sweeps, namely, sweep 1 1511, Shown is PO 1501 with sweep 2 1512 and sweep 3 1513. Sweep 1 1511 is PDCCH MO0 1520, beam sweeping 1530 PDCCH MO11521 sweeping beam 1 1531, and beam 2 1532 The PDCCH MO2 1522 sweeps the beam.

[0088] Alternatively, PO can be expressed as S=(N SSB × R) consecutive PDCCH monitoring occasions may be defined as a set, where N SSB is SystemInformati Determined according to the parameter ssb-PositionsInBurst in onBlock1. R may be the number of SSBs actually transmitted, and R may be the number of SSBs used for paging transmissions. In this example, the K-th paging PDCCH in the PO The monitoring occasion corresponds to the (flooor(K / R))th transmitted SSB. There is a match.

Additional PDCCH monitoring options including PO for scenarios where M>1 are considered here. Cageon may be seen as an extension of PO.

[0095] FIG. 18 is an example 1800 of monitoring an enhanced PO according to one embodiment, which is described herein. May be used in combination with any of the described embodiments. See Figure 18 and multiple extended POs 1810, 1811, 1812, and 1813 are shown. E1 1801 monitors PDCCH monitoring occasions during extended PO1810 However, it is not monitored during the extensions PO1811, 1812 and 1813. UE17 1 802 may monitor PDCCH monitoring occasions during the extended PO1 811. , and does not monitor during the extension PO 1810, 1812 and 1813.

[0098] Table 11 shows the four scenarios for T=32, N=16, Ns=4, M=2 and S=3. PDCCH monitoring OK for extended PO and (i_s+1)th PO for different UEs The result of the i_s calculation for the start number of the PF is shown below. In this example, the SFN of the PF is The same for each UE, but each UE is distributed to different POs within the PF, Therefore, different sets of PDCCH monitoring occasions for paging can be monitored as shown in Figure 18. View.

[0099] [Table 11]

[0100] To optimize power consumption, the channel is If the gNB determines that it has obtained access, the UE There is no need to monitor the H monitoring occasions, and in this case, the D When using one of the methods for signaling L channel access indication UE can take advantage of this.

[0101] For example, if the UE monitors the PDCCH during a PO, it may scrub the P-RNTI. If the gNB receives a PDCCH transmission with a quantized CRC, it will access the channel. The UE can then assume that the next PDCCH monitoring occasion corresponding to the same PO is There's no need to monitor.

[0102] In NR, if one or more UEs need to be paged during a PO, g The NB may transmit only paging DCI. The UE may receive the paging DCI by P-RNTI during the PO. If it fails to detect DCI format 1_0 with scrambled CRC, The UE may assume that it has not been paged and enter DRX until the next PO. In NR-U, whether the UE needs to be paged during the PO or not is determined. The operation of the gNB is modified so that paging DCI may be transmitted during all POs regardless of the The UE may receive a P-RNTI scrambled CRC during the PO. If the detection of DCI format 1_0 fails, the UE transmits paging DCI. It may be assumed that the DL channel was not accessible to the gNB, and the UE may respond accordingly. During a PO, the UE may adapt its own behavior using the methods described herein. If a paging DCI is received by the (short message is read if present in DCI), The paging message carried by the PDSCH is the one for which the scheduling information for paging is It is decrypted if it is present in the CI.

[0103] Scenario when paging DCI is transmitted but there is no UE to be paged To handle this, the gNB must notify the presence of a short message in the DCI. and the short message field bit indicates that no UE is paged. may be set to a default value (if this default value is defined) indicating

[0104] Alternatively, the short message indicator field may be a table illustrating this scenario: 12. In yet another alternative, the UE may To indicate whether a paging DCI has been received, a paging DCI may be used, e.g., a paging indicator. It may contain the following fields:

[0105] [Table 12]

[0106] FIG. 19 illustrates a DL CAI for paging using a paging DCI according to one embodiment. 19 is a flow diagram of an example signaling procedure 1900, which is described herein. In the example of FIG. 19, The NB gains access to the DL channel on the first attempt. B1902 may perform LBT in DL to gain access to the channel (S Step 1911). The gNB 1902 sends the following to indicate that there are no UEs to be paged: The mechanism proposed here may be used to transmit paging DCI during PO. The UE 1901 processes the paging DCI and receives the paged DCI (step 1912). If it is determined that there are no UEs that can receive the next DRX cycle, it may enter DRX (step 1913). During the call, the gNB1902 performs LBT in DL to gain access to the channel. The gNB 1902 may receive one or more paged During a PO, the proposed mechanism is used to indicate that there are a number of UEs The UE 1901 may transmit a paging DCI to the UE 1901 (step 1915). The PDSC processes the paged DCI to determine that there is one or more UEs to be paged. H may prepare to receive the paging message carried by H (step 1916). The gNB 1902 may transmit the paging message (step 1917). 901 processes paging messages and, if paged (i.e., the paging message contains a paging record with the UE's identity), If the connection is not established, the UE enters DRX (step 1918 ).

[0107] FIG. 20 illustrates a DL CAI for paging using a paging DCI according to one embodiment. 20 is a flow diagram of another exemplary signaling procedure 2000, which is described herein. In the example of FIG. , the gNB does not get access to the channel on the first attempt, but gains access to the DL channel on the second attempt. Referring to Figure 20, the gNB2002 performs LBT on the DL. The gNB20 attempts to access the channel but fails to do so (step 2011). UE 2001 does not transmit paging DCI (step 2012). The gNB fails to decode the paging DCI and the gNB does not access the DL channel for the transmission of the paging DCI. In this case, the UE determines that the access was not possible using the mechanism described herein. may be used to adapt its own behavior to monitor the next PO (step 2013 During the same DRX cycle, the gNB2002 performs LBT in DL and The gNB 2002 may obtain access to the paging The mechanism proposed here to indicate that there is one or more UEs that are The Paging DCI may be transmitted during the next PO using the Paging DCI (step 2015). The E2001 processes the paging DCI and notifies the UE or UEs to be paged. may determine that there is a paging message and prepare to receive the paging message carried by the PDSCH. (Step 2016). The gNB 2002 may transmit a paging message (Step The UE 2001 processes the paging message and, when paged, (i.e., when the paging message contains a paging record with the UE's identity) If so, the UE may (re)establish a connection with the network; otherwise, the UE switches to DRX. Enter (Step 2018).

[0108] In another alternative, the UE may receives a PDCCH or a signal transmitted by a gNB, such as a CAI signal; When detecting a demodulation reference signal (DMRS), The UE may determine that the gNB has gained access to the channel.

[0109] In one aspect, DCI-based CAI may be used. New DCI including a parameter indicating Channel Occupancy Time (COT) an RNTI whose format is defined and which is used to indicate DL channel access; For example, it may be transmitted on a PDCCH masked with the CAI-RNTI.

[0110] [Table 13]

[0111] In another aspect, a discovery reference signal (DRS) transmitted by a gNB is DRS may be used to indicate that the gNB has acquired access to the The symbol may be transmitted in, for example, the COT length, the sub-symbol in which channel access is obtained. It may also include channel access information such as band, so that the UE can It is possible to determine the PDCCH monitoring occasions for which the gNB will have access. do.

[0112] In NR-U, the gNB may perform LBT before paging the UE. If the gNB is unable to acquire a channel during the configured PO for a given UE, it will re-establish the UE. The gNB must wait for a full DRX cycle before attempting to page again. In one aspect, the channel may be To reduce the delay associated with paging the UE when the NB is unavailable, the DRX support The cycle may be dynamically shortened, so that the UE is not re-paged. The gNB does not have to wait for the entire DRX cycle before The gNB can select the channel for a predetermined time or, for example, for several consecutive POs. The DRX cycle can be enabled until an event occurs that can be captured. Dynamically to the original value or intermediate value that can be valid for a period of time or until an event occurs May be extended.
