[0014] Wireless communication network

[0015] Figure 1 An exemplary wireless communication network 100 is shown, comprising a core network 110 and a radio access network (RAN) 120. The core network 110 also includes at least one mobility management entity (MME) 112 and / or at least one access and mobility management entity function (AMF). Figure 1 Other functions that may be included in the core network 110 are not shown. The RAN 120 also includes a plurality of base stations, such as base stations 122 and 124. The base station may include at least one evolved Node B (eNB) for 4G LTE, or a next generation Node B (gNB) for 5G New Radio (NR), or any other type of signal transmission / reception device, such as a UMTS Node B. The eNB 122 communicates with the MME 112 via an S1 interface. Both the eNB 122 and the gNB 124 may be connected to the AMF 114 via an Ng interface. Each base station manages and supports at least one cell. For example, the base station gNB 124 may be configured to manage and support cell 1, cell 2, and cell 3.

[0016] The gNB 124 may include a central unit (CU) and at least one distributed unit (DU). The CU and DU may be co-located, or they may be separated at different locations. The CU and DU may be connected via an F1 interface. Alternatively, for an eNB capable of connecting to a 5G network, it may be similarly divided into one CU and at least one DU, referred to as ng-eNB-CU and ng-eNB-DU, respectively. The ng-eNB-CU and ng-eNB-DU may be connected via a W1 interface.

[0017] The wireless communication network 100 may include one or more tracking areas. A tracking area may include a set of cells managed by at least one base station. For example, tracking area 1, labeled 140, includes cell 1, cell 2, and cell 3, and may also include more tracking areas that may be managed by other base stations and in Figure 1 1. The wireless communication network 100 may also include at least one UE 160. The UE may select a cell among a plurality of cells supported by the base station to communicate with the base station via an over-the-air (OTA) wireless communication interface and resources, and may reselect a cell for communication as the UE 160 travels in the wireless communication network 100. For example, the UE 160 may initially select cell 1 to communicate with the base station 124, and then it may reselect cell 2 at some later point in time. The cell selection or reselection of the UE 160 may be based on the wireless signal strength / quality and other factors in the various cells.

[0018] The wireless communication network 100 may be implemented as, for example, a 2G, 3G, 4G / LTE or 5G cellular communication network. Accordingly, base stations 122 and 124 may be implemented as 2G base stations, 3G node Bs, LTE eNBs or 5G NR gNBs. UE 160 may be implemented as a mobile or fixed communication device capable of accessing the wireless communication network 100. UE 160 may include, but is not limited to, a mobile phone, a laptop computer, a tablet computer, a personal digital assistant, a wearable device, an Internet of Things (IoT) device, an MTC / eMTC device, a distributed remote sensor device, a roadside assistance device, an XR device and a desktop computer. UE 160 may also be generally referred to as a wireless communication device or a wireless terminal. UE 160 may support side link communication to another UE via a PC5 interface.

[0019] Although the following description focuses on Figure 1 The cellular wireless communication system shown in FIG. 1 is a cellular wireless communication system, but the basic principles are applicable to other types of wireless communication systems for paging wireless devices. These other wireless systems may include, but are not limited to, Wi-Fi, Bluetooth, ZigBee, and WiMax networks.

The memory 222 may include an operating system 224, instructions 226, and parameters 228. The instructions 226 may be configured for one or more processors 221 to perform the functions of a network node.

For example, the parameters may include network protocol settings, bandwidth parameters, radio frequency mapping allocations, and / or other parameters.

[0022] Figure 3An example of an electronic device implementing a terminal device 300 (e.g., a user equipment (UE)) is shown. UE 300 may be a mobile device, such as a smart phone or a mobile communication module placed in a vehicle. UE 300 may include some or all of the following: a communication interface 302, a system circuit 304, an input / output interface (I / O) 306, a display circuit 308, and a storage device 309. The display circuit may include a user interface 310. System circuit 304 may include any combination of hardware, software, firmware, or other logic / circuits. System circuit 304 may be implemented, for example, with one or more systems on a chip (SoC), application specific integrated circuits (ASICs), discrete analog and digital circuits, and other circuits. System circuit 304 may be part of the implementation of any desired functionality in UE 300. In this regard, the system circuitry 304 may include logic that facilitates, for example, decoding and playing music and video (e.g., MP3, MP4, MPEG, AVI, FLAC, AC3, or WAV decoding and playback); running applications; accepting user input; saving and retrieving application data; establishing, maintaining, and terminating cellular telephone calls or data connections to, for example, make Internet connections; establishing, maintaining, and terminating wireless network connections, Bluetooth connections, or other connections; and displaying relevant information on the user interface 310.

[0023] See also Figure 3, the communication interface 302 may include a radio frequency (RF) transmission (Tx) and reception (Rx) circuit 316, which handles the transmission and reception of signals through one or more antennas 314. The communication interface 302 may include one or more transceivers.

The signals sent and received may follow any of a variety of formats, protocols, modulations (e.g., QPSK, 16-QAM, 64-QAM, or 256-QAM), channels, bit rates, and encodings. As a specific example, the communication interface 302 may include a transceiver that supports transmission and reception under 2G, 3G, BT, WiFi, Universal Mobile Telecommunications System (UMTS), High Speed ​​Packet Access (HSPA) +, 4G / Long Term Evolution (LTE), and 5G standards. However, the techniques described below are applicable to other wireless communication technologies, whether from the 3rd Generation Partnership Project (3GPP), the GSM Association, 3GPP2, IEEE, or other partners or standards bodies.

[0024] See also Figure 3 , the system circuit 304 may include one or more processors 321 and a memory 322. The memory 322 stores, for example, an operating system 324, instructions 326, and parameters 328. The processor 321 is configured to execute the instructions 326 to perform the desired functionality of the UE 300. The parameters 328 may provide and specify configuration and operating options for the instructions 326. The memory 322 may also store any BT, WiFi, 3G, 4G, 5G, or other data that the UE 300 will send or has received through the communication interface 302. In various implementations, the system power of the UE 300 may be supplied by a power storage device such as a battery or a transformer.

[0025] Physical Downlink Control Channel (PDCCH) monitoring

[0026] PDCCH supports data and signaling messages in wireless communication networks and plays a key role in various aspects, including, for example, downlink (DL) scheduling assignments, uplink (UL) scheduling authorizations, power control, paging indications, etc. UEs need to continuously monitor PDCCH in a variety of ways. For example, a UE in a connected state can periodically monitor PDCCH based on a discontinuous reception mode (DRX). For another example, a UE in an idle or inactive state may need to monitor PDCCH for paging DCI, paging messages, system information updates, etc.

[0027] When monitoring PDCCH, the UE needs to turn on certain hardware, such as its RF chain, which increases power consumption. Therefore, reducing the frequency of PDCCH monitoring may help reduce power consumption. The base station can coordinate with the UE to achieve such a goal. For example, the base station may be able to predict or estimate that the UE will have no downlink data / signal to monitor for a duration. The base station can then notify the UE, so the UE can skip PDCCH monitoring for a certain duration, but without adding too much delay.

[0028] Search Space Set Group (SSSG) Switching

[0029] In a wireless communication network, a UE may be configured with one or more search space set groups (SSSGs). Each SSSG may include zero, one or more search space (SS) sets and may have its own characteristics. For example, each SSSG may be associated with a different PDCCH monitoring periodicity and may have a different number of search space sets. The UE may monitor the PDCCH based on one of the SSSGs. If the SSSG is configured with more search space sets and / or a shorter PDCCH monitoring periodicity, the UE may consume more energy.

[0030] Based on the UE service characteristics, the base station can instruct the UE to switch from one SSSG to another SSSG in order to meet specific performance requirements and minimize UE power consumption.

[0031] UE PDCCH monitoring behavior

[0032] In this disclosure, various UE PDCCH monitoring behaviors are described. These behaviors can be categorized into two types: the first type involves UE PDCCH monitoring skipping (for a specific duration), while the second type involves UE SSSG switching.

[0033] The first type of PDCCH monitoring behavior may include:

[0034] • Deactivate PDCCH monitoring skipping (ie, deactivate the PDCCH monitoring skipping feature), or monitor PDCCH according to the search space set configuration.

[0035] • Skip PDCCH monitoring for a duration.

[0036] In one implementation, deactivating PDCCH monitoring skipping may mean not triggering or activating PDCCH monitoring skipping behavior. In another implementation, deactivating PDCCH monitoring skipping may mean that the UE monitors PDCCH according to the search space set configuration.

[0037] There may be multiple durations for which the UE may skip monitoring. Each duration corresponds to a UE PDCCH monitoring behavior. For example, the multiple durations may include 5 milliseconds and 10 milliseconds. Each duration represents a behavior. For example, one behavior may be "skip PDCCH monitoring 5 milliseconds" and another behavior may be "skip PDCCH monitoring 10 milliseconds". In this way, the UE may be configured with a list of skipped PDCCH monitoring behaviors, each behavior corresponding to a specific duration.

[0038] The second type of PDCCH monitoring behavior may include:

[0039] - Stop monitoring the search space (SS) set associated with searching SSSG#1 and SSSG#2 (if configured) and monitoring the SS set associated with SSSG#0.

[0040] - Stop monitoring the search space (SS) set associated with searching SSSG#0 and SSSG#2 (if configured) and monitoring the SS set associated with SSSG#1.

[0041] - Stop monitoring the search space (SS) set associated with searching SSSG#0 and SSSG#1 and monitoring the SS set associated with SSSG#2.

[0042] In the present disclosure, the first type of PDCCH monitoring behavior may also be referred to as PDCCH monitoring skipping behavior, and the second type of PDCCH monitoring behavior may also be referred to as SSSG switching behavior.

[0043] In the present disclosure, there may be a first PDCCH monitoring behavior subset including a first type of PDCCH monitoring behavior and a second PDCCH monitoring behavior subset including a second type of PDCCH monitoring behavior. The PDCCH monitoring behavior set includes these two behavior subsets. In one implementation, when the UE starts monitoring a search space (SS) set associated with a specific SSSG, the UE may choose to stop monitoring SS sets associated with other SSSGs. Control UE PDCCH monitoring behavior

[0044] In this disclosure, various embodiments for controlling UE PDCCH monitoring behavior are described. Figure 4 Exemplary steps for the control process in a high level are illustrated.

[0045] Step 401a: The UE may send its UE capability information related to PDCCH monitoring to the base station. The UE capability information may be used as a reference for the base station. The UE capability information may be referenced when the base station configures the UE PDCCH monitoring behavior in step 401 and instructs the UE to select the PDCCH monitoring behavior in step 402. For example, the UE capability information may indicate the maximum number of PDCCH monitoring behaviors that the UE can support, or the maximum number of bits that the UE can process in order to target / select the PDCCH monitoring behavior. For example, a low-end UE may be able to process only one bit for PDCCH monitoring behavior selection, while other UEs may process two or more bits. This step may be performed before or after step 401. Further details about this step will be described in later sections.

[0046] Step 401: The base station sends a configuration message to the UE for configuring the PDCCH monitoring behavior. The configuration message may include a list of PDCCH monitoring behaviors that need to be configured to the UE. This configuration method is called explicit configuration. The configuration message may also include a list of parameters related to the PDCCH monitoring behavior, and the parameter list implicitly indicates the PDCCH monitoring behavior. For example, the parameter list may include a list of PDCCH monitoring skip durations, such as 2 milliseconds, 5 milliseconds, and 10 milliseconds. Each duration corresponds to a PDCCH monitoring behavior that skips PDCCH monitoring during the duration. That is, these three PDCCH monitoring behaviors will be configured: skip PDCCH monitoring for 2 milliseconds, skip PDCCH monitoring for 5 milliseconds, and skip PDCCH monitoring for 10 milliseconds. The SSSG switching behavior may be indicated by a parameter list such as an SSSG number / index. This configuration method is called implicit configuration because the PDCCH monitoring behavior is derived from these parameters. The list of PDCCH monitoring skip durations and the list of SSSG numbers / indexes can be sent to the UE in various ways. For example, they can be sent together in one signaling, or they can each be sent separately in one signaling.

[0047] Step 402: The UE has a list of PDCCH monitoring behaviors configured according to the configuration message in step 401. In order to trigger a change in the PDCCH monitoring behavior, the base station sends a control message to the UE to indicate the specific PDCCH monitoring behavior that the UE needs to apply (or activate). The control message may be in the form of a downlink control information (DCI) message. The PDCCH monitoring behavior indication information may be carried in a DCI field of the DCI message.

[0048] Step 403: The UE decodes the control message (e.g., DCI field) to obtain the indicated PDCCH monitoring behavior. In order to decode the DCI field, the UE may need to first determine the bit width of the DCI field. In one implementation, the UE may determine the indicated PDCCH monitoring behavior based on a mapping relationship between a code point of the DCI field and the PDCCH monitoring behavior. In the present disclosure, the DCI field may include at least one bit and the code point is a value represented by the at least one bit. The DCI field may represent multiple code points using different bit combinations.

[0049] Step 404: The UE applies the indicated PDCCH monitoring behavior. For example, the UE may skip PDCCH monitoring for a duration associated with, or specified in, the indicated PDCCH monitoring behavior. For example, the UE may skip PDCCH monitoring for 5 milliseconds or 10 milliseconds, as determined by the indicated PDCCH monitoring behavior. For another example, the UE may start monitoring the search space set associated with SSSG#2 and stop monitoring the search space sets associated with SSSG#0 and SSSG#1.

[0050] Further details are described below.

[0051] PDCCH monitoring behavior configuration

[0052] In one implementation, the base station may determine a list of UE PDCCH monitoring behaviors and send the list to the UE. Alternatively, the base station may determine a list of parameters related to the UE PDCCH monitoring behaviors. When determining the list, several factors are involved. These factors may include: UE capabilities;

[0053] ●predetermined values / rules; and

[0054] • The bit width of the DCI field carrying the indicator for PDCCH monitoring behavior selection.

[0055] These factors may be considered individually or in combination.

[0056] In one implementation, the UE capability includes a maximum number of indication bits for indicating the selection of PDCCH monitoring behaviors supported by the UE, or a number of indication bits (denoted as M) for indicating the selection of PDCCH monitoring behaviors supported by the UE. In one implementation, the number of PDCCH monitoring behaviors supported by the UE is not greater than 2. M Alternatively, the total number of configured SSSGs and / or PDCCH skip durations should not be greater than 2. M .

[0057] In one implementation, the UE capability or predetermined value includes at least one of the following: ● a maximum number of PDCCH monitoring actions supported by the UE;

[0058] ● The maximum number of PDCCH skip durations supported by the UE; or ● The maximum number of SSSGs supported by the UE.

[0059] ●The number of PDCCH monitoring actions supported by the UE;

[0060] ● The number of PDCCH skip durations supported by the UE; or ● The number of SSSGs supported by the UE.

[0061] In one implementation, the number of configured UE PDCCH monitoring behaviors shall be less than or equal to: the maximum number of PDCCH monitoring behaviors supported by the UE; or the sum of the maximum number of PDCCH skip durations supported by the UE and the maximum number of SSSGs supported by the UE. In one implementation, the number of configured UE PDCCH monitoring skip behaviors shall be less than or equal to the maximum number of PDCCH skip durations supported by the UE. In one implementation, the number of configured UE SSSG switching behaviors shall be less than or equal to the maximum number of SSSGs supported by the UE. In one implementation, the number of configured UE PDCCH monitoring behaviors shall be less than or equal to: the number of PDCCH monitoring behaviors supported by the UE, or the sum of the number of PDCCH skip durations supported by the UE and the number of SSSGs supported by the UE. In one implementation, the number of configured UE PDCCH monitoring skip behaviors shall be less than or equal to the number of PDCCH skip durations supported by the UE. In one implementation, the number of configured UE SSSG switching behaviors shall be less than or equal to the number of SSSGs supported by the UE.

[0062] In one implementation, the configuration of the UE PDCCH monitoring behavior is based on the bit width of the DCI field carrying the indicator for the PDCCH monitoring behavior selection (see Figure 2 Step 402 in the DCI field). For example, if the bit width of the DCI field is configured as 1 bit, and the UE capability indicates support for two PDCCH monitoring skipping behaviors, then only 1 or 2 PDCCH skip monitoring durations may be configured. For another example, if the bit width of the DCI field is configured as 1 bit, then even if the UE capability indicates support for 3 SSSG switching behaviors, only 2 SSSGs may be configured. For example, two SSSGs may be configured as "switched to" SSSGs. In one implementation, the UE may be configured with different types of SSSGs. For example, there may be a first type SSSG. The first type SSSG may include at least one of the following:

[0063] ● An SSSG that is not configured with a search space set (e.g., an empty SSSG);

[0064] ● Dormant SSSG;

[0065] ● an SSSG associated with which the UE may stop monitoring the PDCCH for a duration, or before expiry of a timer; or

[0066] ● SSSGs associated with indices greater than or equal to 2 (indicating that there are more than 2 SSSGs in the SSSG set, and SSSG indices start from 0).

[0067] In one implementation, it is not expected that both the first type SSSG and the PDCCH skip duration are configured to the UE.

[0068] In one implementation, it is not expected that the first type SSSG is configured with the same timer value as the PDCCH skipping duration.

[0069] In one implementation, if the first condition is met, it is not desirable to configure a certain type of PDCCH monitoring behavior:

[0070] This specific type of PDCCH monitoring behavior includes deactivating PDCCH monitoring skipping.

[0071] The first condition may be associated with at least one of the following: high-layer signaling, or UE capability. The first condition is satisfied if the following conditions are satisfied:

[0072] ●Configure at least two SSSGs;

[0073] ● PDCCH skip duration is not configured;

[0074] ● Configure at least one default SSSG. In some embodiments, the default SSSG means the SSSG in which the UE monitors the PDCCH if no PDCCH monitoring behavior indication is received; or

[0075] ●Configure the first type SSSG.

[0076] In one implementation, if the bit width of the DCI field is 1, only one type of PDCCH monitoring behavior may be configured for the UE.

[0077] In one implementation, if the bit width of the DCI field is 1 and the UE capability indicates support for SSSG switching behavior, two SSSG switching behaviors may be configured for the UE.

[0078] Control signal mapping

[0079] like Figure 4As shown in, in step 403, the UE needs to determine the indicated PDCCH monitoring behavior based on a control message (e.g., a DCI message). In one implementation, the DCI field of the DCI message may carry the indication information. The UE may map the value of the DCI field (e.g., a code point (CP)) to a specific PDCCH monitoring behavior. In one implementation, the mapping may also be performed based on a bitmap formed by the bits of the DCI field.

[0080] Figure 5 An example of using code points to map UE PDCCH monitoring behavior is shown. In this example, the DCI field has 2 bits (i.e., the bit width is 2 bits) and there are 4 code points based on these 2 bits. The UE is configured with 6 PDCCH monitoring behaviors. Each duration represents a PDCCH monitoring skip duration, and each SSSG represents an SSSG switching behavior. Figure 5 As shown in , 4 out of 6 PDCCH monitoring behaviors are mapped with code points. In the present disclosure, various embodiments for mapping are disclosed.

[0081] In some embodiments, each SSSG may be associated with or indicated by a SSSG index. Figure 5 As shown in , index 2 may indicate SSSG 2. Further, the maximum SSSG index may also indicate the number of SSSGs configured, for example, in the SSSG list or in the second PDCCH monitoring behavior subset.

[0082] When the UE maps the indication in the control message to a specific PDCCH monitoring behavior, several factors are involved. These factors include:

[0083] ●The bit width of the DCI field;

[0084] ●High-level signaling;

[0085] ● Multiple PDCCH monitoring behaviors configured for the UE (e.g., configured via RRC signaling from the base station);

[0086] ● Multiple PDCCH monitoring behavior types configured for the UE.

[0087] UE capabilities;

[0088] ● Predefined rules; or

[0089] ●Predefined conditions.

[0090] These factors may be considered individually or in combination.

[0091] In order to decode the DCI field, the UE may need to first obtain the bit width of the DCI field.

[0092] In one implementation, if the number of PDCCH monitoring behaviors configured for the UE is M, the bit width of the DCI field may be determined as A is an integer greater than 0.

[0093] In one implementation, if the number of first-type PDCCH monitoring behaviors configured for the UE is M, and the number of second-type PDCCH monitoring behaviors configured for the UE is N, the bit width of the DCI field may be determined as A is an integer greater than 0

[0094] In one implementation, if only one type of PDCCH monitoring behavior is configured for the UE, the bit width may be determined to be 1. If two types of PDCCH monitoring behaviors are configured for the UE, the bit width may be determined to be 2.

[0095] In one implementation, the bit width of the DCI field may be determined by the UE capability. The UE capability includes a maximum number of indication bits (i.e., DCI bits) for indicating the selection of PDCCH monitoring behavior supported by the UE. For example, the bit width of the DCI field is determined by Determined by: where A is the total number of configured PDCCH monitoring behaviors, and B is the maximum number of indication bits used to indicate the selection of PDCCH monitoring behaviors supported by the UE.

[0096] DCI may have different formats. A first type DCI may include a DCI having a DCI format 0-2, or a DCI having a DCI format 1-2. A second type DCI may include a DCI having a DCI format 1-1, or a DCI having a DCI format 0-1.

[0097] In one implementation, if the DCI is a first type DCI, the bit width of the DCI field may be A bits. If the DCI is a second type DCI, the bit width of the DCI field may be B bits. A and B are predetermined values, or are determined according to higher layer signaling and UE capabilities of the UE.

[0098] In one implementation, if the DCI is a first type DCI, the bit width of the DCI field may be 1 bit. If the DCI is a second type DCI, the bit width of the DCI field may be max(2, B) bits, where B is the maximum number of indication bits for indicating the selection of the PDCCH monitoring behavior supported by the UE, which may be indicated or reported by the UE capability.

[0099] In one implementation, if the DCI is a first type DCI, the bit width of the DCI field may be 1 bit. If the DCI is a second type DCI, the bit width of the DCI field may be min(A, B) bits, where A is the bit width configured by high-layer signaling, and B is the maximum number of indication bits used to indicate the selection of the PDCCH monitoring behavior supported by the UE.

[0100] In one implementation, the code points of the DCI may be mapped to the PDCCH monitoring behavior according to the order of the parameter list in the configuration message. For example, if the configuration message configures a parameter list related to the UE PDCCH monitoring behavior, the code points of the DCI may be mapped to the PDCCH monitoring behavior based on the order of the elements in the list. For example, the code point value m is mapped to the mth PDCCH monitoring behavior in the list.

[0101] In one implementation, the code point of the DCI may be mapped to the PDCCH monitoring behavior. For example, the UE may be configured with M PDCCH skip durations and no SSSG. If M is less than 4, then the first code point in the DCI (e.g., the minimum code point or a code point with an all-zero value) means that the behavior is "deactivate PDCCH monitoring skip". Other code point values ​​may have a mapping relationship with the PDCCH skip duration. For example, each configured PDCCH skip duration may be associated with an index. The code point value m may indicate a PDCCH skip duration with index m-1. If M=4, the code point value m indicates a PDCCH skip duration with index m. The index associated with the PDCCH skip duration may be indicated by higher layer signaling (e.g., RRC signaling that configures the PDCCH monitoring behavior to the UE).

[0102] Table 1 below shows an example PDCCH monitoring behavior mapping, where the UE is configured with only 1 PDCCH monitoring skip duration. It should be understood that the "deactivate PDCCH monitoring skip" behavior may not need to be explicitly configured into the UE PDCCH monitoring behavior list.

[0103] Table 1: PDCCH monitoring behavior mapping

[0104] Code Point PDCCH monitoring behavior 0 Deactivate PDCCH monitoring skip 1 Skip PDCCH monitoring during the first duration

[0105] Table 2 below shows another example PDCCH monitoring behavior mapping, where the UE is configured with 4 PDCCH monitoring skipping durations. Not shown in Table 5, each duration may be associated with an index, and a code point may be mapped to the index.

[0106] Table 2: PDCCH monitoring behavior mapping

[0107]

[0108]

[0109] In one implementation, the UE is configured with M (M is an integer) PDCCH skip durations, and the UE may or may not be configured with SSSG switching behavior. If there is one code point remaining after indicating all PDCCH monitoring behaviors, the remaining code point may be mapped to "deactivate PDCCH monitoring skip". Table 3 below shows an example with two remaining code points.

[0110] Table 3: PDCCH monitoring behavior mapping

[0111] Code Point PDCCH monitoring behavior 00(Remaining CP) Deactivate PDCCH monitoring skip 01 Skip PDCCH monitoring for duration 1 10 Skip PDCCH monitoring during duration 2 11(Remaining CP) Deactivate PDCCH monitoring skip

[0112] Table 4 below shows an example where there is one remaining code point.

[0113] Table 4: PDCCH monitoring behavior mapping

[0114] Code Point PDCCH monitoring behavior 00 SSSG switched to SSSG 0 01 SSSG Switch to SSSG 1 10 Skip PDCCH monitoring for duration 1 11(Remaining CP) Deactivate PDCCH monitoring skip

[0115] In one implementation, the UE is configured with M PDCCH monitoring skip durations and N SSSG switching behaviors, where M and N are both integers. The "Deactivate PDCCH monitoring skip" behavior is not mapped. That is, no codepoint in the DCI field is mapped to this behavior. Alternatively, if at least one SSSG switching behavior is configured and the total number of configured PDCCH monitoring behaviors is greater than 4, the "Deactivate PDCCH monitoring skip" behavior is not mapped.

[0116] In one implementation, when mapping the PDCCH monitoring behavior, one type of UE PDCCH monitoring behavior is first mapped, followed by another type of UE PDCCH monitoring behavior. For example, the first type of PDCCH monitoring behavior is first mapped, followed by the second type of PDCCH monitoring behavior. The mapping order may be predetermined or configured by high-level signaling. Table 5 below shows an example of first mapping the second type of PDCCH monitoring behavior, followed by mapping the first type of PDCCH monitoring behavior.

[0117] Table 5: PDCCH monitoring behavior mapping

[0118] Code Point PDCCH monitoring behavior 00 SSSG switched to SSSG 0 01 SSSG Switch to SSSG 1 10 Skip PDCCH monitoring for duration 1 11(Remaining CP) Do not map / or deactivate PDCCH monitoring skip

[0119] In one implementation, the UE is configured with M PDCCH skip durations and N SSSG switching behaviors, and the bit width of the DCI field is 2. The first two code points (i.e., "00" and "01") may be mapped to one or two PDCCH monitoring skip behaviors, and the remaining two code points (i.e., "10" and "11") may be mapped to one or two SSSG switching behaviors.

[0120] In one implementation, the UE is configured with M PDCCH skip durations and N SSSG switching behaviors, and the bit width of the DCI field is 2 (i.e., 4 code points are supported). The first I code points (e.g., I=3) can be mapped to one type of PDCCH monitoring behavior, and the remaining code points (e.g., I=1) can be mapped to another type of PDCCH monitoring behavior.

[0121] In one implementation, the mapping method can be configured by high-level signaling. For example, media access control-control unit (MACCE) signaling can indicate mapping information, such as a method for mapping DCI code points to PDCCH monitoring behaviors. For another example, each PDCCH monitoring behavior can be associated with an index. The index can be assigned by the base station to the corresponding PDCCH monitoring behavior when configuring the PDCCH monitoring behavior for the UE. The code point in the DCI field can indicate the corresponding PDCCH monitoring behavior based on the index. For example, the code point value m can indicate a PDCCH monitoring behavior with an index m, where m is a non-negative integer. The index can also be assigned according to a predetermined rule. For another example, RRC signaling can indicate mapping information, such as a method for mapping DCI code points to PDCCH monitoring behaviors.

[0122] In one implementation, if the total number of PDCCH monitoring behaviors configured for the UE is greater than the maximum number of mappings that the DCI field can support (eg, due to a limited number of bits in the DCI field), some PDCCH monitoring behaviors may not be mapped.

[0123] In some embodiments, the mapping method may be based on at least one of the following: higher layer signaling, UE capabilities, or predefined information.

[0124] In one implementation, the maximum number of bit widths supported by the UE capability indication (i.e., the bit width of the DCI field used to map the indication) is 1. The code point may indicate two first-type PDCCH monitoring behaviors, such as "deactivate PDCCH monitoring skip" behavior and "skip PDCCH monitoring for a duration" behavior. The code point may also indicate two second-type PDCCH monitoring behaviors.

[0125] In one implementation, if the maximum number of bit widths supported by the UE capability indication (i.e., the bit width of the DCI field used to map the indication) is 1, at most one of two specific SSSG switching behaviors may be mapped. The two specific SSSG switching behaviors may be predetermined or configured by higher layer signaling or an SSSG other than the default SSSG. Alternatively, one skip PDCCH monitoring behavior and one SSSG switching behavior may not be mapped.

[0126] In one implementation, more than one type of DCI may be used to indicate a PDCCH monitoring behavior. For example, a first type of DCI may be used to indicate a mapping to a first type of PDCCH monitoring behavior, and a second type of DCI may be used to indicate a mapping to a second type of PDCCH monitoring behavior. The type of DCI may be determined by its DCI format.

[0127] In one implementation, multiple PDCCH monitoring behavior sets can be configured for a UE. For example, the configuration information may include information for two PDCCH monitoring behavior sets, and the configuration information may be sent to the UE in the same message or in different messages. Different types of DCI may be used to indicate PDCCH monitoring behaviors in different PDCCH monitoring behavior sets. The type of DCI may be based on a DCI format. For example, a first type of DCI may be used to indicate the mapping of PDCCH monitoring behaviors in a PDCCH monitoring behavior set, and a second type of DCI may be used to indicate the mapping of PDCCH monitoring behaviors in another PDCCH monitoring behavior set.

[0128] In one implementation, predefined information or UE capabilities may indicate: the maximum number of PDCCH skip durations that can be mapped, and / or the maximum number of SSSG switching behaviors that can be mapped. For example, the UE is configured with 2 PDCCH skip durations and 3 SSSG switching behaviors. According to the predefined information, the maximum number of PDCCH skip durations that can be mapped is 1, and the maximum number of SSSG switching behaviors that can be mapped is 3. Only one PDCCH skip duration (e.g., the first one) and all 3 SSSG switching behaviors may be mapped.

[0129] In one implementation, the bit width of the DCI field may be indicated to the UE via RRC signaling. The RRC signaling may include the same RRC signaling as that for configuring the PDCCH monitoring behavior of the UE, or other RRC signaling.

[0130] In one implementation, the method for mapping DCI code points to PDCCH monitoring behaviors is through a predefined rule (eg, predefined by a protocol).

[0131] In one implementation, RRC signaling may indicate that the bit width of the DCI field is 1. The code point of the DCI field may indicate two first-type PDCCH monitoring behaviors, such as "deactivate PDCCH monitoring skip" behavior and "skip PDCCH monitoring for a duration" behavior (if they are configured to the UE). The code point may also indicate two second-type PDCCH monitoring behaviors, if they are configured to the UE.

[0132] In one implementation, if RRC signaling indicates that the bit width of the DCI field is 1, then 2 specific SSSG switching behaviors may not be mapped. These 2 specific SSSG switching behaviors may be predetermined, or configured through higher layer signaling, or SSSGs other than the default SSSG. Alternatively, one skip PDCCH monitoring behavior and one SSSG switching behavior may not be mapped.

[0133] In one implementation, the first type of PDCCH monitoring behavior and the mapping of the first type of SSSG may not be supported simultaneously.

[0134] In one implementation, if the total number of PDCCH monitoring behaviors is greater than 4, the mapping of the first type of PDCCH monitoring behavior and the first type of SSSG may not be supported simultaneously.

[0135] In one implementation, if the total number of PDCCH monitoring behaviors is greater than 4, the first type SSSG may not be mapped.

[0136] In one implementation, a portion of bits in the DCI field indicates a PDCCH monitoring behavior subset, and another portion of bits in the DCI field indicates a PDCCH monitoring behavior in the PDCCH monitoring behavior subset. Table 6 below shows an example with 2 bits in the DCI field.

[0137] Table 6: PDCCH monitoring behavior mapping

[0138]

[0139] Mapping Examples

[0140] In the present disclosure, various PDCCH monitoring behavior mapping examples are described below.

[0141] Example 1

[0142] In this example, the UE is configured with 3 monitoring skip durations (corresponding to 3 behaviors) and 3 SSSGs (3 behaviors for switching to 3 SSSGs). The bit width of the DCI field is 2. Among the 3 SSSGs, SSSG 2 is a first type SSSG. The first type SSSG is described in the previous section.

[0143] The following Table 6 shows two mapping methods. Since SSSG 2 is a first-type SSSG, neither method maps a behavior of switching to SSSG 2.

[0144] Table 7: PDCCH monitoring behavior mapping

[0145]

[0146] Example 2

[0147] Example 2 is similar to Example 1, except that SSSG 2 is not a first type SSSG. Table 7 below shows three mapping methods.

[0148] Table 8: PDCCH monitoring behavior mapping

[0149]

[0150] In method 3, SSSG switches to SSSG 2 which is mapped to code point 10 in binary.

[0151] Example 3

[0152] In this example, the UE is configured with 4 PDCCH monitoring skip durations (corresponding to 4 behaviors) and 2 SSSGs (2 behaviors for switching to 2 SSSGs). The bit width of the DCI field is 2. The mapping method maps 2 SSSGs and 2 PDCCH monitoring skip durations as shown in Table 8 below.

[0153] Table 9: PDCCH monitoring behavior mapping

[0154] Code Point Mapping 00 SSSG switched to SSSG 0 01 SSSG Switch to SSSG 1 10 PDCCH monitoring skipped in duration 1 11 PDCCH monitoring skipped during duration 2

[0155] UE capability signaling

[0156] See also Figure 4 In step 4a, the UE may send its UE capabilities to the base station via a message (eg, UE capability signaling).

[0157] The signaling may use various conditions of the DCI so that it is used to indicate the PDCCH monitoring behavior.

[0158] For example, the condition includes a DCI format. The signaling may indicate whether the UE supports a specific format of DCI for indicating PDCCH monitoring behavior. The DCI format may include:

[0159] ●DCI 0_1;

[0160] ●DCI 1_1;

[0161] DCI 0_2; or

[0162] ●DCI 1_2;

[0163] The signaling may indicate whether the UE supports using a DCI having a format of DCI 0_1 or DCI 1_1, or a DCI having a format of DCI 0_2 or DCI 1_2, to indicate the second type of PDCCH monitoring behavior.

[0164] For another example, the condition includes a specific field in the DCI, such as a secondary cell (Scell) sleep indication field. The signaling may indicate whether the Scell ​​sleep indication field in the DCI may be used for indication.

[0165] For another example, the condition includes the function of the DCI. For example, the signaling may also indicate whether a DCI that does not include a data scheduling indication can be used for the indication.

[0166] The above conditions may be used alone or in combination. In addition, the above conditions may be used for the first type PDCCH monitoring behavior and / or the second type PDCCH monitoring behavior.

[0167] Example UE Capability Signaling

[0168] The following list shows various examples that UE capability signaling may indicate:

[0169] ● Whether the UE supports selection of a PDCCH monitoring behavior from the second PDCCH monitoring behavior subset indicated by DCI 0_1 or / and DCI 1_1;

[0170] ●Whether the UE supports selection of a PDCCH monitoring behavior from the second PDCCH monitoring behavior subset indicated by DCI 0_2 or / and DCI 1_2;

[0171] ●Whether the UE supports the use of the Scell ​​dormancy indication field to select a PDCCH monitoring behavior from the second PDCCH monitoring behavior subset;

[0172] ●Whether the UE supports selection of a PDCCH monitoring behavior from the second PDCCH monitoring behavior subset using a DCI including an Scell ​​dormancy indication field and without a data scheduling indication; ●Whether the UE supports selection of a PDCCH monitoring behavior from the first PDCCH monitoring behavior subset indicated by DCI 0_1 or / and DCI 1_1;

[0173] ● Whether the UE supports selection of PDCCH monitoring behavior from the first PDCCH monitoring behavior subset indicated by DCI 0_2 or / and DCI 1_2;

[0174] ●Whether the UE supports the use of the Scell ​​dormancy indication field to select a PDCCH monitoring behavior from the first PDCCH monitoring behavior subset;

[0175] ●Whether the UE supports selection of a PDCCH monitoring behavior from a first PDCCH monitoring behavior subset using a DCI including an Scell ​​dormancy indication field and without a data scheduling indication; ●Whether the UE supports selection of a PDCCH monitoring behavior from a first and a second PDCCH monitoring behavior subset indicated by DCI 0_1 and / or DCI 1_1;

[0176] ● Whether the UE supports selection of PDCCH monitoring behavior from the first and second PDCCH monitoring behavior subsets indicated by DCI 0_2 and / or DCI 1_2;

[0177] ●Whether the UE supports the use of the Scell ​​dormancy indication field to select the PDCCH monitoring behavior from the first and second PDCCH monitoring behavior subsets;

[0178] ● Whether the UE supports selection of a PDCCH monitoring behavior from the first and second PDCCH monitoring behavior subsets using a DCI including an Scell ​​dormancy indication field and without a data scheduling indication;

[0179] ●Whether the UE supports empty SSSG or dormant SSSG. or

[0180] • Whether the UE supports performing PDCCH monitoring for hybrid automatic repeat request (HARQ) retransmissions during the retransmission period when the UE is instructed to skip PDCCH monitoring and / or switch to a "dormant" / "null" SSSG.

[0181] A dormant SSSG includes an SSSG associated with a search space set. When associated with a dormant SSSG, the UE does not monitor the PDCCH for a duration (or before a timer expires).

[0182] An empty SSSG means that the SSSG is not associated with any search space set.

[0183] In one implementation, in addition to using the Scell ​​sleep indication field to indicate the Scell ​​sleep indication information, some other DCI fields may also be used. These fields include at least one of the following: a modulation and coding scheme field for transport block 1, a new data indicator field for transport block 1, a redundancy version field for transport block 1, a HARQ process number field, a (multiple) antenna port field, and a DMRS sequence initialization field. For example, if the DCI does not carry a data scheduling indication, these fields may be used for the Scell ​​sleep indication.

[0184] Example of codepoint mapping with PDCCH monitoring behavior

[0185] Various examples of codepoint mapping are described in this section. A codepoint refers to a codepoint of a DCI field that carries PDCCH monitoring behavior indication information.

[0186] In one implementation, if the bit width of the DCI field is 1 and SSSG 0 is configured, the code point may be mapped to at least the SSSG monitoring behavior associated with SSSG 0.

[0187] In one implementation, if the bit width of the DCI field is 1, the code point may be mapped to a PDCCH monitoring behavior belonging to the same PDCCH monitoring behavior subset.

[0188] In one implementation, if two types of PDCCH monitoring behaviors are configured, the codepoint may be mapped to at least a SSSG monitoring behavior associated with SSSG 0 and a SSSG monitoring behavior associated with SSSG 1.

[0189] In one implementation, if both types of PDCCH monitoring behaviors are configured, the codepoint may be mapped to one of the SSSG monitoring behavior associated with SSSG0 or the deactivated PDCCH monitoring skipping behavior.

[0190] In one implementation, a code point may be mapped to a PDCCH monitoring behavior belonging to a subset of PDCCH monitoring behaviors supported by the UE as indicated by the UE capabilities.

[0191] In one implementation, if at least one PDCCH monitoring skip duration is configured, the first type SSSG may not be mapped.

[0192] In one implementation, a code point may be mapped to a deactivation PDCCH monitoring skipping behavior only when the first type PDCCH monitoring behavior subset is configured.

[0193] In one implementation, a code point in the DCI field may be mapped to M PDCCH monitoring behaviors, where M is an integer and is not greater than a predetermined value.
