[0015] Section headings are used in the present document only to improve readability and do not limit scope of the disclosed embodiments and techniques in each section to only that section. Furthermore, some embodiments are described with reference to Third Generation Partnership Project (3GPP) Fifth Generation (5G) New Radio (NR) or Sixth Generation (6G) standard for ease of understanding and the described technology may be implemented in different wireless system that implement protocols other than the NR or 6G protocol.
[0016] 1. Initial discussion
[0017] In order for obtain network energy saving gain and reduce the negative impact on some traditional user equipment (UEs) from base station’s perspective, there are more than one active common signal / channel configurations supported, where one configuration is for traditional UEs, while other configurations are for new UEs that support newer protocols. In case that system load (e.g., number of UEs in an area) is low, the configuration for traditional UEs can be activated for network energy saving, while in case that system load is high, more than one configuration may be activated to let UEs have more signal / channel to perform measurement, synchronization and access in the cell. To this end, this document discloses, among other techniques, mechanisms for triggering different common signal / channel configurations and how to detect the signaling for triggering the configurations.
[0018] According to output in previous meeting of Third Generation Partnership Project (3GPP) , the adaptation mechanism of synchronization signal / physical broadcast channel block (SS / PBCH block) (SSB) are proposed, as shown in timeline 100 in FIG. 1.
[0019] Assuming two SSB configuration are configured by semi-static signaling, one is for Rel-15 to Rel-18 UEs (legacy / traditional UEs) , another is for new UEs (Rel-19 and beyond UEs) . The SSBs in the SSB configuration for legacy UEs are transmitted as a default option, while the SSBs in the SSB configuration for new UEs are transmitted based on the triggering signaling.
[0020] According to output in previous meeting, the adaptation mechanism of physical random access channel (PRACH) is shown in the timeline 200 in FIG. 2.
[0021] Assuming two PRACH configuration are configured by semi-static signaling, one is for legacy / traditional UEs, another is for new UEs. The SSBs in the SSB configuration for legacy UEs are transmitted normally, or by default, while the SSBs in the SSB configuration for new UEs are transmitted based on the triggering signaling.
[0022] The technical logic of other common signal / channel configuration activation includes: from UE’s perspective, it receives the signaling for adaptation firstly, then UE assumes that the common signal / channel is transmitted in the time point / instance after an application delay T, and the common signal / channel is valid within an effect time after an application delay T.
[0023] Among other new techniques disclosed in the present document for operations improvements to mechanisms of common signal / channel configuration adaptation, the following are briefly mentioned as an introduction:
[0024] The interpretation of a signaling for adaptation (named as a first signaling) .
[0025] The interpretation of an application delay (named as a first delay) .
[0026] The interpretation of a first time point / instance (time point instance) .
[0027] The interpretation of an effect time duration (e.g., the duration for which the signaling will take effect) .
[0028] The interpretation of a common signaling / channel configuration (named as a first configuration (for new UEs, including e.g., Rel-19 and beyond UEs) and a second configuration (for legacy UEs, including e.g., Rel-15, Rel-16, Rel-17 and Rel-18 UEs) .
[0029] According to some embodiments, a method may include receiving, by the wireless device, a control signaling associated with the first configuration and / or a second configuration, receiving, by the wireless device, a first signaling associated with the first configuration, performing a wireless operation in a plurality of resources determined by the first configuration, and the availability of the first configuration is determined by at least one of a first delay, a first time point, or an effect time duration.
[0030] According to some embodiments, a method for wireless communication (e.g., method 610 show in FIG. 6A) includes receiving (612) , by a wireless device from a network device, a first signaling determining availability of a first configuration, and performing (614) , by the wireless device, a wireless operation in a plurality of resources determined by the first configuration. Here, the availability of the first configuration is determined by at least one of a first delay, a first time point or an effect time duration.
[0031] From a network device perspective, a method for wireless communication (e.g., method 620 depicted in FIG. 6B) includes transmitting (622) , by a network device to a wireless device, a first signaling indicating an availability of a first configuration, and facilitating (624) , based on the first signaling, performing a wireless operation by the wireless device according to a first delay, a first time point or an effect time duration associated with the first configuration.
[0032] 2. Example embodiments of the first signaling
[0033] In some embodiments, the first signaling is a downlink control information (DCI) signaling. In an embodiment, the DCI signaling is a DCI format 1_0 scrambled by paging -radio network temporary identifier (P-RNTI) , which is named as paging DCI in this document. In an embodiment, one or more first bit fields in the paging DCI are re-interpreted as an adaptation information when one or more second bit fields are set to a predetermined value. In some cases, the second bit field comprises / is short message indicator. In some cases, the bit fields in the paging DCI include at least one of short message indicator, short message, scheduling information for paging, tracking reference signal (TRS) availability indication or the adaptation information. In some cases, the bit fields in the paging DCI is determined by the short message indicator. In this case, the one state of the short message indicator corresponds to one kind of combination of the bit fields in paging DCI. For example, short message indicator is set to the predetermined value ‘01’ , meaning the bit fields in DCI signaling include scheduling information for paging and TRS availability indication and the adaptation information. In this case, the ‘01’ in short message indicator denotes that only scheduling information for paging, TRS availability indication if trs-ResourceSetConfig is configured, and adaptation information are present in DCI. As another example, short message indicator is set to the predetermined value ‘10’ , meaning the bit fields in DCI signaling include short message, TRS availability indication and the adaptation information. In this case, the ‘10’ in short message indicator denotes that only short message, TRS availability indication if trs-ResourceSetConfig is configured, and the adaptation information are present in DCI. For other example, alternatively, short message indicator is set to the predetermined value ‘00’ , meaning the bit fields in the DCI signaling include scheduling information for paging, and the adaptation information. In this case, the ‘00’ in short message indicator denotes that scheduling information for paging and the adaptation information are present in DCI. Alternatively, short message indicator is set to the predetermined value ‘00’ , meaning the bit fields in the DCI signaling include short message, and the adaptation information. In this case, the ‘00’ in short message indicator denotes that short message and the adaptation information are present in DCI. Alternatively, short message indicator is set to the predetermined value ‘00’ , meaning the bit fields in the DCI signaling include TRS availability, and the adaptation information. In this case, the ‘00’ in short message indicator denotes that TRS availability if trs-ResourceSetConfig is configured and the adaptation information are present in DCI. For other example, short message indicator is ‘00’ , meaning the bit fields in the DCI signaling include short message, scheduling information for paging, TRS availability indication and the adaptation information. In this case, the ‘00’ in short message indicator denotes that short message, scheduling information for paging, TRS availability if trs-ResourceSetConfig is configured, and adaptation information are present in DCI signaling. In this case, the last three bits of short message field are re-interpreted for the adaptation information. In an embodiment, the bit field of short message indicator is included in DCI signaling.
[0034] In some embodiments, the first signaling is a downlink control information (DCI) signaling. In an embodiment, the DCI signaling is a paging DCI. In an embodiment, one or more first bit fields in the paging DCI are re-interpreted as an adaptation information when one or more second bit fields are set to all ‘1’ or all ‘0’ . In some cases, the second bit field comprises / is short message indicator. In some cases, the bit field of the adaptation information is determined by re-interpretation of one or more bit fields in the paging DCI signaling. In some cases, one or more second bit fields include at least one of short message, short message indicator, scheduling information for paging, or TRS availability indication. In some cases, the bit field of scheduling information for paging comprises a bit field of frequency domain resource assignment, a bit field of time domain resource assignment, a bit field of a virtual resource block to physical resource block (VRB-to-PRB) mapping, a bit field of a modulation and coding scheme, and a bit field of a transport block (TB) scaling. In some cases, the first bit fields include at least one of short message, TRS availability indication, frequency domain resource assignment, time domain resource assignment, a virtual resource block to physical resource block (VRB-to-PRB) mapping, a modulation and coding scheme, and a transport block (TB) scaling. . For example, the second bit field comprising short message bit field set to all one, the first bit field comprising TRS availability indication is re-interpreted as the adaptation information. As another example, the second bit field comprising short message bit field set to all one, the scheduling information for paging field (including a bit field of frequency domain resource assignment, a bit field of time domain resource assignment, a bit field of a virtual resource block to physical resource block (VRB-to-PRB) mapping, a bit field of a modulation and coding scheme, and a bit field of a transport block (TB) scaling) is re-interpreted as the adaptation information. In some cases, the second fields comprise one or more bit fields in the scheduling information for paging. In some cases, the first fields comprise one or more bit fields in the scheduling information for paging. In this case, when the second fields comprising frequency domain resource assignment, the time domain resource assignment, and the modulation and coding scheme are set to all zeros, the first bit field comprising TB scaling field is re-interpreted as the adaptation information or the first bit field comprising VRB-to-PRB mapping field is re-interpreted as the adaptation information, or first bit fields comprising both TB scaling field and VRB-to-PRB mapping field are re-interpreted as the adaptation information. Here, re-interpretation means that the meaning of bits of a particular field will be interpreted differently by a legacy device that operates according to a legacy protocol, and by a new device that operates according to a new protocol that is newer than the legacy protocol. In this case, the frequency domain resource assignment is set to all ones, the time domain resource assignment is set to all ones, and the modulation and coding scheme is set to all ones, the TB scaling field is re-interpreted as the adaptation information or the VRB-to-PRB mapping field is re-interpreted as the adaptation information, or both TB scaling field and VRB-to-PRB mapping field are re-interpreted as the adaptation information.
[0035] In some embodiments, the bit fields in DCI signaling is based on a higher layer parameter (e.g., a radio resource control RRC parameter) . In some cases, if a higher layer parameter for adaptation information is configured, the size of one or more bit fields in paging DCI is limited. For example, when a higher layer parameter for adaptation information is configured, the size of bit field of TRS availability indication is limited. Alternatively, a higher layer parameter for TRS availability indication is not configured (e.g., trs-ResourceSetConfig is not configured) . Alternatively, a higher layer parameter for TRS availability indication is limited (e.g., maximum value of indBitID [maximum is 6 previously] in trs-ResourceSetConfig is limited to 4) .
[0036] In some embodiments, the first signaling is a DCI signaling. In an embodiment, the DCI signaling is a DCI format 2_7 scrambled by paging early indication -radio network temporary identifier (PEI-RNTI) , which is named as PEI in the document. In some cases, the wireless device in RRC_CONNECTED mode monitors the PEI. For example, A wireless device is provided a search space set by pei-SearchSpace, a number of frames by pei-FrameOffset, a number of symbols by firstPDCCH-MonitoringOccasionOfPEI-O, a size by payloadSizeDCI-2-7, a number of subgroups per paging occasion by subgroupsNumPerPO and a number of paging occasions associated with the number of physical downlink control channel (PDCCH) monitoring occasions for PEI by po-NumPerPEI for detection of a PEI in RRC_IDLE state, in RRC_INACTIVE state, or in RRC CONNECTED state. In some cases, the bit fields in the PEI include paging indication field, TRS availability indication and the adaptation information. In some cases, the bit field of the adaptation information is behind the bit field of TRS availability indication.
[0037] In some embodiments, the first signaling is a DCI signaling. In an embodiment, the DCI signaling is a DCI format 2_9 with CRC scrambled by cell discontinuous transmission / reception (CellDTRX) -radio network temporary identifier (CellDTRX-RNTI) . For example, a wireless device configured for operation on a serving cell according to one or both of a cell discontinuous transmission (DTX) operation and a cell discontinuous reception (DRX) operation by cellDTXDRX-Config for the serving cell, is provided by dci-Format2-9 a Type3-PDCCH CSS set to monitor PDCCH for detection of DCI format 2_9 in RRC_IDLE state, in RRC_INACTIVE state, or in RRC CONNECTED state. In some cases, the bit fields in the DCI format 2_9 include one or more information blocks. In this case, the bit field in each information block includes Cell DTX / DRX indication, NES-mode indication and adaptation information. In this case, the bit field of the adaptation information is behind the bit field of Cell DTX / DRX indication in each information blocks. In some cases, the bit field in the DCI format 2_9 include one or more information blocks and the adaptation information. In this case, the bit field in each information block includes Cell DTX / DRX indication and NES-mode indication. In this case, the bit field of the adaptation information is behind the bit field of information block with block number Nc, where Nc is an integer denoting the index of last information block in the DCI format 2_9.

In an embodiment, the DCI signaling is a DCI format 1_0 scrambled by system information -radio network temporary identifier (SI-RNTI) , which is named as SI DCI in the following. In some cases, the bit fields of the SI DCI include frequency domain resource assignment, time domain resource assignment, VRB-to-PRB mapping, modulation and coding scheme, redundancy version, system information indicator, adaptation information and reserved bits. In some cases, the first N2 reserved bits in the SI DCI are used for the bit field of adaptation information, where N2 is a positive integer. In some cases, the bit field for adaptation information in the SI DCI is between the bit field of system information indicator and the reserved bits.

[0045] In some embodiments, the first signaling is monitored in a secondary cell.
[0046] In some embodiments, the wireless device monitors a subset of the first resource for receiving the first signaling in the search space set. In an embodiment, the subset of the first resources is determined by at least one of the following parameters: a time window, one or more offsets for 1st available first resources, a number of available first resources, a synchronization signal block index, or a periodicity of available first resources. In an embodiment, the 1st available first resources are the 1st available first resources in the time window. In some cases, the time window determines a time duration for first resources. In this case, a wireless device monitors the first resources within a time duration. In some cases, the offset for 1st available first resources determines the starting of the time duration. In some cases, the offset for 1st available first resources determines the starting of the time window. In some cases, the number of available first resources determines the number of first resources a wireless device monitors. In some cases, the number of available first resources determines the number of first resources a wireless device monitors in the time window. In some cases, the synchronization signaling block index is the candidate SS / PBCH blocks in a half frame are indexed in an ascending order in time from 0 to Lmax -1, where Lmax is a positive integer denoting the maximum number of SS / PBCH block indexes in a cell. In some cases, the periodicity of available first resources determines the distance between the 1st available first resources in one time window and the 1st available first resources in another time window. In some cases, the periodicity of available first resources determines the distance between one time window and another time window.
[0047] In an embodiment, the subset of the first resources is determined by the time window. In some cases, the time window is determined by a higher layer parameter. In some cases, the first resource is PDCCH monitoring occasion. In this case, the higher layer parameter is radio resource control (RRC) signaling. In this case, the higher layer parameter provides a number of slots. Alternatively, the higher layer parameter provides a number of consecutive slots. For example, the higher layer parameter is set to 10 slots, which means the available first resources are within the configured 10 slots. Alternatively, the higher layer parameter provides the length of the time window in unit of second or millisecond. Alternatively, the higher layer parameter provides a number of downlink slots. Alternatively, the higher layer parameter provides a number of PDCCH monitoring occasions. Alternatively, the higher layer parameter is si-WindowLength-r19. As other example, in FIG. 3B, there are 8 PDCCH monitoring occasions configured in the search space set. The high layer parameter for the length of time window is set to 4 PDCCH monitoring occasions. Then, the wireless device monitors the first signaling in the first 4 four PDCCH monitoring occasions (denoted as available first resources in FIG. 3B) of the configured 8 slots.
[0048] In an embodiment, the subset of the first resources is determined by the time window and a plurality of the offsets for 1st available first resources. In some cases, the first resources are PDCCH monitoring occasions. In some cases, the time window is determined by a higher layer parameter. In this case, the higher layer parameter comprises a RRC signaling. In some cases, the plurality of the offsets are determined by a high layer parameter. Alternatively, the higher layer parameter for the plurality of the offsets determines the slot index for the first PDCCH monitoring occasion of the time window. Alternatively, the higher layer parameter for the plurality of the offsets determines the PDCCH monitoring occasion index of the time window. For one example, in FIG. 3C, there are 15 PDCCH monitoring occasions configured in the search space set. The high layer parameter for the length of time window is set to 4 PDCCH monitoring occasions. And there are 3 offsets for the 1st available first resources, which are denoted as (offset1, offset2, offset3) = (0, 5, 10) , where the first element in the bracket denotes the starting PDCCH monitoring occasion index for the first time window, the second element in the bracket denotes the starting PDCCH monitoring occasion index for the second time window, and the third element in the bracket denotes the starting PDCCH monitoring occasion index for the third time window. In this case, the 3 offsets are configured in a parameter in RRC signaling in type of a sequence. The configuration is illustrated in FIG. 3C.
[0049] In an embodiment, the subset of the first resources is determined by the time window and a periodicity of the available first resources. In some cases, the first resources are PDCCH monitoring occasions. In some cases, the time window is determined by a higher layer parameter. In this case, the higher layer parameter comprises a RRC signaling. In some cases, the periodicity of the available first resources determined by a high layer parameter. Alternatively, the higher layer parameter for the periodicity of the available first resources determines the distance between the first PDCCH monitoring occasion in the previous time window and the first PDCCH monitoring occasion in the following time window. Alternatively, the higher layer parameter for the periodicity of the available first resources determines the distance between two adjacent time window. For one example, in FIG. 3D, there are 15 PDCCH monitoring occasions configured in the search space set. The high layer parameter for the length of time window is set to 4 PDCCH monitoring occasions. And the periodicity of the available first resources is 5 PDCCH monitoring occasions. The configuration is illustrated in FIG. 3D.
[0050] In an embodiment, the subset of the first resources is determined by a plurality of offsets for 1st available first resource and a synchronization signaling block index. In some cases, the first resources are the PDCCH monitoring occasions. In some cases, the synchronization signaling block index comprises / is the maximum number of SSB index. In some cases, the synchronization signal block index comprises / is the maximum number of transmitted SSB index. In some cases, each PDCCH monitoring occasion corresponds to one SSB index. For one example, in FIG. 3E, there are 15 PDCCH monitoring occasion configured in the search space set. The maximum number of SSB indexes is set to 4. And the periodicity of the available first resources is 5 PDCCH monitoring occasions. The configuration is illustrated in FIG. 3E.
[0051] In some embodiments, the subset of the first resources includes resources for monitoring paging DCI. In an embodiment, the subset of the first resources are the resources for monitoring paging DCI. In some cases, the first resources for monitoring the first signaling is the same as the resources for monitoring paging DCI. In some cases, the first resources are PDCCH monitoring occasions. In this case, the PDCCH monitoring occasions for monitoring the first signaling are the same as the PDCCH monitoring occasions for monitoring paging DCI.
[0052] In an embodiment, the subset of the first resources are the subset of the resources for monitoring paging DCI. In some cases, the first resources are the resources for monitoring paging DCI in the first paging occasion in the paging cycle. In this case, the PDCCH monitoring occasions for monitoring the first signaling are the PDCCH monitoring occasions for paging DCI in the first paging occasion in the paging cycle. In some cases, the first resources are the resources for monitoring paging DCI in the last paging occasion in the paging cycle. In this case, the PDCCH monitoring occasions for monitoring the first signaling are the PDCCH monitoring occasions for paging DCI in the last paging occasion in the paging cycle. In some cases, the first resources are the resources for monitoring paging DCI in the predefined paging occasions in the paging cycle. In this case, the PDCCH monitoring occasions for monitoring the first signaling are the PDCCH monitoring occasions for paging DCI in the predefined paging occasions in the paging cycle. In this case, the predefined paging occasions are determined by a higher layer parameter. In this case, the number of predefined paging occasions can be one.
[0053] In an embodiment, the subset of the first resources are the subset of the resources for monitoring paging DCI. In some cases, the first resources are the subset of the resources for monitoring paging DCI in the first paging frame in the paging cycle. In this case, the PDCCH monitoring occasions for monitoring the first signaling are the PDCCH monitoring occasions for paging DCI in the first paging frame in the paging cycle. In some cases, the first resources are the subset of the resources for monitoring paging DCI in the last paging frame in the paging cycle. In this case, the PDCCH monitoring occasions for monitoring the first signaling are the PDCCH monitoring occasions for paging DCI in the last paging frame in the paging cycle. In some cases, the first resources are the resources for monitoring paging DCI in the predefined paging frames in the paging cycle. In this case, the PDCCH monitoring occasions for monitoring the first signaling are the PDCCH monitoring occasions for paging DCI in the predefined paging frames in the paging cycle. In this case, the predefined paging occasions are determined by a higher layer parameter. In this case, the higher layer parameter comprises RRC signaling.

[0093] In some embodiments, the second offset is the interval between the reference time point and a first time point. In an embodiment, the first time point is a time point of availability of the first configuration. In some cases, the first configuration is available at the first time point. In some cases, the first configuration is available after the first time point. In some cases, the first time point is the slot boundary of the 1st resource in the first configuration. In some cases, the first time point is the beginning symbol of the 1st resource in the first configuration. In this case, the 1st resource comprises the 1st resource configured in the first configuration.

[0182] The disclosed and other embodiments, modules and the functional operations described in this document can be implemented in digital electronic circuitry, or in computer software, firmware, or hardware, including the structures disclosed in this document and their structural equivalents, or in combinations of one or more of them. The disclosed and other embodiments can be implemented as one or more computer program products, i.e., one or more modules of computer program instructions encoded on a computer readable medium for execution by, or to control the operation of, data processing apparatus. The computer readable medium can be a machine-readable storage device, a machine-readable storage substrate, a memory device, a composition of matter effecting a machine-readable propagated signal, or a combination of one or more of them. The term “data processing apparatus” encompasses all apparatus, devices, and machines for processing data, including by way of example a programmable processor, a computer, or multiple processors or computers. The apparatus can include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, or a combination of one or more of them. A propagated signal is an artificially generated signal, e.g., a machine-generated electrical, optical, or electromagnetic signal, that is generated to encode information for transmission to suitable receiver apparatus.
[0183] A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment. A computer program does not necessarily correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document) , in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code) . A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.
[0184] The processes and logic flows described in this document can be performed by one or more programmable processors executing one or more computer programs to perform functions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit) . Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read only memory or a random-access memory or both. The essential elements of a computer are a processor for performing instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto optical disks, or optical disks. However, a computer need not have such devices. Computer readable media suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto optical disks; and CD ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.
[0185] It is noted that operation of the wireless communications as disclosed herein causes a reduction in greenhouse gas emissions compared to traditional methods. The International Energy Agency (IEA) estimates that the overall share of carbon emissions from information and communication technologies (ICT) accounts for approximately 4%of the total amount of CO2 emitted around world. Further, conventional networks can sometimes exacerbate the causes of climate change. For example, at an average of approximately 485g of CO2 per KWh of electricity that is produced worldwide, it results in a rough estimate of 145.5 million metric tons of CO2. The implementations disclosed herein for operating the wireless communications can reduce power consumption by improving efficiency of channel state reporting and reducing signaling overhead and latency.
[0186] Moreover, Global System for Mobile Communications Association (GSMA) , the organization that represents mobile operators and the telecommunication industry worldwide, has estimated that currently 20–40%of the operating cost of network operators is taken up by electricity, and that 5G can cause a substantial (as much as four to five fold) increase of energy consumption in the RAN, but that the technical means to reduce this consumption can be included in later generation mobile networks, such as 6G networks. Avoiding unnecessary resources for handovers that may not be successful or optimal, by using the pre-verification techniques described herein, may cause less wireless message transmissions. Therefore, the disclosed implementations for operation of the wireless communications mitigates climate change and the effects of climate change.
