Abstract
Description
[Technical field]
[0001] (Technical field) The present disclosure is directed generally to wireless communications. In particular, the present disclosure relates to methods, devices, and systems for determining a location of a paging early indication (PEI). [Background technology]
[0002] (background) Wireless communication technologies are moving the world towards an increasingly connected and networked society. High-speed and low-latency wireless communication relies on efficient network resource management and allocation between one or more user equipments and one or more radio access network nodes (including, but not limited to, base stations). It is expected that new generation networks will provide high-speed, low-latency, and ultra-reliable communication capabilities to meet requirements from different industries and users.
[0003] With the rapid evolution of cellular mobile communication systems, for example, in current wireless telecommunication protocols, a user equipment (UE) may need to monitor a paging occasion (PO) in each paging cycle or paging time window (PTW), so that the UE can obtain a paging message according to the paging occasion. However, under most circumstances, the UE may not have a paging message in every paging cycle, and therefore actively monitoring the paging occasion may result in unnecessary power consumption. This problem / problem may be difficult for some UEs with a relatively low paging probability, which may detect a larger number of unnecessary paging occasions and cause unnecessarily high power consumption. A paging early indication (PEI) with indication information before the PO may be used to indicate whether the UE needs to receive a paging physical downlink control channel (PDCCH). This scheme may reduce the power consumption caused by redundant paging reception. One of the problems / problems may be how to allow the UE to accurately locate the PEI and reduce the power consumption caused by blind detection.
[0004] The present disclosure describes various embodiments for determining a location of a paging early indication (PEI) that address at least one of the problems / challenges discussed above. Various embodiments in the present disclosure may reduce and / or conserve power consumption, increase the efficiency of monitoring paging occasions, and / or improve the accuracy of receiving paging messages, thus improving the user experience and / or technology field in wireless communications.

[0019] (Detailed Description) The present disclosure will now be described in detail hereinafter with reference to the accompanying drawings, which form a part hereof and which show, by way of illustration, specific examples of embodiments. It should be noted, however, that the present disclosure can be embodied in a variety of different forms, and thus, the subject matter covered or claimed should not be construed as being limited to any of the embodiments that will be described below.
[0020] Throughout this specification and the claims, terms may have subtle meanings that are suggested or implied in the context beyond the explicitly stated meaning. Similarly, the phrases "in one embodiment" or "in some embodiments" as used herein do not necessarily refer to the same embodiment, and the phrases "in another embodiment" or "in other embodiments" as used herein do not necessarily refer to different embodiments. The phrases "in one implementation" or "in some implementations" as used herein do not necessarily refer to the same implementation, and the phrases "in another implementation" or "in other implementations" as used herein do not necessarily refer to different implementations. For example, it is intended that the claimed subject matter includes a combination of example embodiments or implementations, whether in whole or in part.
[0021] Generally, terminology may be understood, at least in part, from usage in context. For example, terms such as "and," "or," or "and / or" as used herein may include various meanings that may depend, at least in part, on the context in which such terms are used. Typically, "or," when used to relate a list such as A, B, or C, is intended to mean A, B, and C, which is used herein in an inclusive sense, as well as A, B, or C, which is used herein in an exclusive sense. In addition, the terms "one or more" or "at least one," as used herein, may be used to describe any feature, structure, or characteristic in a singular sense, or may be used to describe a combination of features, structures, or characteristics in a plural sense, at least in part, depending on the context. Similarly, again, terms such as "a," "an," or "the" may be understood to convey a singular use or to convey a plural use, at least in part, depending on the context. Additionally, the terms "based on" or "determined by" may be understood as not necessarily intended to convey an exclusive set of factors, and instead may, again depending at least in part on the context, allow for the existence of additional factors not necessarily explicitly described.
[0022] This disclosure describes various methods and devices for determining a location of a paging early indication (PEI).
[0023] With the rapid evolution of cellular mobile communication systems, for example, in current wireless telecommunication protocols, a user equipment (UE) may need to monitor paging occasions (POs) in each paging cycle, for example, each discontinuous reception (DRX) cycle, so that the UE can obtain paging messages according to the paging occasions. However, under most circumstances, the UE may not have paging messages in all paging cycles, and thus actively monitoring paging occasions may result in unnecessary power consumption. This task / problem may be difficult for some UEs with a relatively low paging probability, which may cause a larger number of unnecessary paging messages to be received, causing unnecessarily high power consumption.
[0024] In some implementations, a paging early indication (PEI) with indication information before the PO can indicate whether the UE needs to receive a paging physical downlink control channel (PDCCH) within the PO. This can reduce the power consumption caused by paging reception. In some implementations, different PEI locations can result in different power saving effects.
[0025] In some implementations, one PEI may indicate multiple POs in different PFs. One of the issues / problems may include how to enable UEs corresponding to different POs to find the same PEI. In some other implementations, different PEI locations may result in different power saving gains. Therefore, in order to enable the UE to accurately locate the PEI and reduce the power consumption caused by blind detection, one of the issues / problems may include how the UE locates the PEI.
[0026] The present disclosure describes various embodiments for determining a location of a paging early indication (PEI) that address at least one of the problems / challenges discussed above. Various embodiments in the present disclosure may reduce and / or conserve power consumption, increase the efficiency of monitoring paging occasions, and / or improve the accuracy of receiving paging messages, thus improving the user experience and / or technology field in wireless communications.
[0027] In various embodiments, the UE may monitor one paging occasion (PO) per discontinuous reception (DRX) cycle (i.e., paging cycle). A paging frame (PF) is one radio frame (RF) and may contain one or more POs or the start of a PO. The PF and PO for paging may be determined by the following formula: The system frame number (SFN) for the PF is (SFN+PF_offset) mod T=(T div N). * The PO index (i_s) is determined by (UE_ID mod N), and an index (i_s) indicating the index of the PO is determined by i_s=floor(UE_ID / N) mod Ns, where T indicates the DRX cycle of the UE, N indicates the number of total paging frames in T, Ns indicates the number of paging opportunities for the PF, PF_offset indicates the offset used for PF determination, and UE_ID indicates the fifth generation (5G) system temporary mobile subscription identifier (5G-S-TMSI) mod 1024.
[0028] In some other embodiments, N * The value of Ns may determine the number of POs in a DRX cycle, which is the density of POs in the DRX cycle, where N is the number of total paging frames in the DRX cycle and Ns is the number of paging opportunities for a PF.
[0029] In some other embodiments, the location of the PEI may be determined by a frame level offset and a symbol level offset. The frame level offset may be an offset at the frame level from a start of a first paging frame (PF) of at least one PF associated with a PEI-O to a reference point. The symbol level offset may be an offset at the symbol level from a reference point to a start of a first physical downlink control channel (PDCCH) monitoring opportunity of the PEI-O.
[0030] FIG. 1 illustrates a wireless communication system 100 including a radio network node 118 and one or more user equipments (UEs) 110. The radio network nodes may include network base stations, which may be nodeBs (NBs, e.g., gNBs, eNBs) in a mobile communication context. The UEs may each wirelessly communicate with the radio network nodes over one or more radio channels 115. For example, a first UE 110 may wirelessly communicate with the radio network node 118 over a channel including multiple radio channels for a period of time. The network base station 118 may transmit upper layer signaling to the UE 110. The upper layer signaling may include configuration information for communication between the UE and the base station. In one implementation, the upper layer signaling may include a radio resource control (RRC) message.

The exemplary electronic device 200 may include wireless transmit / receive (Tx / Rx) circuitry 208 for transmitting / receiving communications with UEs and / or other base stations. The electronic device 200 may also include network interface circuitry 209 for allowing the base station to communicate with other base stations and / or core networks, e.g., optical or wired interconnects, Ethernet, and / or other data transmission media / protocols. The electronic device 200 may optionally include an input / output (I / O) interface 206 for communicating with an operator or the like.

The system circuitry 304 may be part of an implementation of any desired functionality in the UE 300. In that regard, system circuitry 304 may include, as examples, logic to facilitate decoding and playing music and video, e.g., MP3, MP4, MPEG, AVI, FLAC, AC3, or WAV decoding and playback, launching applications, receiving user input, storing and retrieving application data, as one example, establishing, maintaining, and terminating cellular calls or data connections for Internet connectivity, establishing, maintaining, and terminating wireless network connections, Bluetooth connections, or other connections, and displaying related information on user interface 310. User interface 310 and input / output (I / O) interface 306 may include a graphical user interface, a touch-sensitive display, tactile feedback or other tactile output, voice or facial recognition input, buttons, switches, speakers, and other user interface elements.Additional examples of I / O interface 306 may include microphones, video and still cameras, temperature sensors, vibration sensors, rotation and orientation sensors, headset and microphone input / output jacks, Universal Serial Bus (USB) connectors, memory card slots, radiation sensors (e.g., IR sensors), and other types of inputs.
[0034] 3, the communication interface 302 may include radio frequency (RF) transmit (Tx) and receive (Rx) circuitry 316 that handles transmission and reception of signals through one or more antennas 314. The communication interface 302 may include one or more transceivers.

[0039] In some implementations, the UE may monitor a paging indication (PEI) in a PEI opportunity (PEI-O). In some other implementations, the PEI may be carried on a downlink control information (DCI), e.g., DCI format 2_7. The PEI-O location may be determined by a reference point and a symbol level offset from the reference point to the start of the first PDCCH monitoring opportunity (MO) of the PEI-O. The reference point may be the start of a reference frame, determined by a frame level offset from the start of the first paging frame (PF) of the PF associated with the PEI-O.

[0050] In some other implementations, the first PF is determined by an index of a PO (i_PO) among POs associated with the PEI and a number of POs (Ns) for the PF. When the value of i_PO is less than or equal to Ns, the first PF is the UE's PF, and / or when the value of i_PO is greater than Ns, the first PF is the PF previous to the UE's PF. The distance between the previous PF and the UE's PF may be T / N radio frames (RF). The SFN of the previous PF may be equal to the SFN-T / N of the UE's PF. In some implementations, the distance between the previous PF and the UE's PF is the distance between the start of the previous PF and the start of the UE's PF.

[0066] In some other implementations, the range of the frame level offset is determined based on at least one of the following: a synchronization signal block (SSB) transmission period, a type of UE, a type of paging cycle or discontinuous reception (DRX) cycle, a value of the paging cycle or DRX cycle, or a UE capability.
[0067] In various embodiments of the present disclosure, referring to FIG. 5, a frame level offset (PEI-F_offset, 510) may be an offset from a reference point of a reference frame (502) to the start of a first paging frame (PF-1, 508) of paging frames (PF-1 and PF-2) associated with a PEI. In various embodiments of the present disclosure, a "first" paging frame (e.g., PF-1 in FIG. 5) of paging frames may refer to an "earliest" paging frame (e.g., PF-1 and PF-2 in FIG. 5) of paging frames associated with a PEI in the time domain, rather than simply "one" paging frame of paging frames. As shown in FIG. 5, PF-1 includes two POs, i.e., one PO with i_s=0 and i_PO=0 and another PO with i_s=1 and i_PO=1, and / or PF-2 includes two POs, i.e., one PO with i_s=0 and i_PO=2 and another PO with i_s=1 and i_PO=3.
[0068] In some implementations, one value may be configured for the frame-level offset.
[0069] In some other implementations, there may be a list of frame-level offsets (also referred to as a frame-level offset list). The number of candidates for the frame-level offset list may be determined based on at least one of the following: the number of POs associated with one PEI, the number of PFs in one paging cycle, and / or the number of POs in one PF.
[0070] In some other implementations, the number of candidate values in the frame-level offset list may be equal to the number of POs associated with one PEI.
[0071] In some other implementations, the frame-level offset corresponding to the (i_PO+1)th PO may be the (i_PO+1)th value in the frame-level offset list.
[0072] In some other implementations, the reference frame of the PEI corresponding to the (i_PO+1)th PO may be the (i_PO+1)th value in the frame-level offset list.
[0073] In some other implementations, the number of candidate values in the frame-level offset list may be equal to the number of PEIs in one frame, or equal to the number of PEIs corresponding to one reference point.
[0074] In some other implementations, the SFN value of the PEI is not greater than the SFN value of the first SFN or the SFN value of the paging frame that the UE monitors.
[0075] In some other implementations, the frame-level offset corresponding to the (i_s+1)th PO is
number
[0076] In some other implementations, the first PDCCH monitoring opportunity number of the PEI corresponding to the (i_s+1)th PO is
number
[0077] In some other implementations, the range of the frame level offset is determined by at least one of the following: SSB transmission period, UE type, UE capability, type of paging cycle or DRX cycle, value of paging cycle or DRX cycle.
[0078] In some other implementations, the minimum value of the frame-level offset may be zero.
[0079] In some other implementations, when the value of the frame level offset may be equal to 0, the PEI may be located before the paging PDCCH monitoring opportunity in the frame. That is, the symbol level offset of the PEI may be less than the value of the firstPDCCH-MonitoringOccasionOfPO. The parameter firstPDCCH-MonitoringOccasionOfPO may be used to determine the first PDCCH monitoring opportunity of the paging PDCCH.
[0080] In some other implementations, the minimum value of the frame-level offset may be a positive integer, i.e., the frame-level offset may not be zero.
[0081] In some other implementations, the maximum value of the frame level offset may be determined by at least one of the following: SSB transmission period, UE type, UE capability, type of paging cycle or DRX cycle, and / or value of paging cycle or DRX cycle.
[0082] In some other implementations, the frame level offset is a value. The value of the frame level offset is determined by the periodicity of the SSB. For example, the value is greater than or equal to N times the SSB transmission period, where N is a positive integer. For example, N=1, N=2, N=3, N=5.
[0083] In some other implementations, the frame-level offset is a range containing multiple values, and the maximum value of the frame-level offset satisfies a condition that the maximum value of the frame-level offset is greater than or equal to N times the SSB period, where N is a positive integer, e.g., N=1, N=2, N=3, and / or N=5. In some other implementations, the range of the frame-level offset is {0,1,2,...,N * SSB period}.
[0084] In some other implementations, the frame level offset is a value. The value of the frame level offset is determined by the UE type. For example, for a non-reduced capability (non-RedCap) UE, the value of the frame level offset is 6, and for a reduced capability (RedCap) UE, the value of the frame level offset is 10 ms.
[0085] In some other implementations, the frame level offset is a range containing multiple values, and the range or maximum value of the frame level offset is determined by the UE type or DRX type. For example, for a non-RedCap UE, the maximum value of the frame level offset is 6, and for a RedCap UE, the maximum value of the frame level offset is 10, and the unit of the frame level offset is radio frames, i.e., 10 ms. In some other implementations, the range of the frame level offset is {0, 1, 2, ..., X}, where X is determined by the UE type or DRX type.
[0086] In some other implementations, the frame level offset is determined by the periodicity of the SSB and the UE type.
[0087] In some other implementations, the frame level offset is a single value. The value of the frame level offset is determined by the periodicity of the SSB and the UE type.
[0088] In some other implementations, the value of the frame level offset is greater than or equal to N times the SSB period, where N is a positive integer, and the value of N is different for different UE types. For example, for non-RedCap UEs, N is equal to 2, and for RedCap UEs, N is equal to 5. That is, the value of the frame level offset is greater than or equal to 4 for non-RedCap UEs, and the value of the frame level offset is greater than or equal to 10 for RedCap UEs.
[0089] In some other implementations, the frame level offset is a range containing multiple values, and the range or maximum value of the frame level offset is determined by the periodicity of the SSB and the UE type.
[0090] In some other implementations, the maximum value of the frame level offset is determined by the periodicity of the SSB and the UE type.
[0091] In some other implementations, the maximum value of the frame level offset is greater than or equal to N times the SSB period, where N is a positive integer, and the value of N is different for different UE types or DRX types. For example, for a non-RedCap UE, N is equal to 3, and for a RedCap UE, N is equal to 5. The maximum value of the frame level offset is greater than or equal to 6 for a non-RedCap UE, and the value of the frame level offset is greater than or equal to 10 for a RedCap UE. The unit of the frame level offset is a frame, i.e., 10 ms. In some other implementations, the range of the frame level offset is {0, 1, 2, ..., N * SSB period}, where N is determined by the UE type or DRX type.
[0092] In some other implementations, the range or maximum value of the frame level offset is determined by the type of paging cycle or DRX cycle. In some embodiments, the range or maximum value of the frame level offset for a UE configured with an e-DRX (extended DRX) cycle is larger than that of a UE with a generic DRX or paging cycle configuration. For example, for a UE with a generic DRX or paging cycle, the range of the frame level offset is 0 to 6, while for a UE with an e-DRX configuration, the range of the frame level offset is 0 to 20.
[0093] In some other implementations, the maximum value of the frame level offset for a UE with an e-DRX configuration is m times that of a UE with a general DRX configuration, where m may be a positive integer.
[0094] In various embodiments of the present disclosure, referring to FIG. 6, the symbol level offset (610) may be an offset from the reference point (602) to the start of the first PDCCH monitoring opportunity of the PEI (PEI1, 604). In some embodiments, the symbol level offset may be provided by an upper layer parameter, e.g., firstPDCCH-MonitoringOccasionOfPEI-O. In various embodiments of the present disclosure, the "first" PDCCH monitoring opportunity of a PEI (e.g., PEI1 in FIG. 6) of one or more PDCCH monitoring opportunities of the PEI may refer to the "earliest" PDCCH monitoring opportunity of the PEI among the PDCCH monitoring opportunities of the PEI in the time domain, rather than simply "one" PDCCH monitoring opportunity of the PEI.
[0095] In some implementations, there may be a list of symbol level offsets (or referred to as a symbol level offset list) that includes one or more symbol level offsets, e.g., with reference to Figure 6, symbol level offset-1 (610), which corresponds to PEI1 (604), and symbol level offset-2 (620), which corresponds to PEI2 (606). As shown in Figure 6, a paging frame (PF) includes four POs, namely, a first PO with i_s=0 and i_PO=0, a second PO with i_s=1 and i_PO=1, a third PO with i_s=2 and i_PO=0, and a fourth PO with i_s=3 and i_PO=1.
[0096] In various embodiments, the number of at least one candidate for the symbol level offset list is determined based on at least one of the following: the number of PEIs in a frame, the number of POs associated with the PEIs, or the number of POs in a PF.
[0097] In some implementations, the symbol-level offset corresponding to the (i_s+1)th PO is
number
[0098] In some other implementations, the range of the symbol level offset is determined based on at least one of the following: a subcarrier spacing (SCS) of the UE, a number of total paging frames in a paging cycle, or a paging cycle.

[0100] In some other implementations, the range of the symbol level offset is determined based on the SCS of the UE, and * In response to the 140 m KHz symbol level offset, the range is from 0 to (140 * m-1), where m=2 n where n is a non-negative integer.
[0101] In some other implementations, the range of the symbol level offset is determined based on the SCS of the UE and the number of total paging frames in a paging cycle.
[0102] In some other implementations, the SCS of the UE is 15 * m KHz, and the number of total paging frames in a paging cycle is equal to the paging cycle, the symbol level offset ranges from 0 to (140 * m-1), where m=2 n where n is a non-negative integer and the UE's SCS is 15 * m KHz, and the number of total paging frames in a paging cycle is equal to half the paging cycle, the symbol level offset ranges from 0 to (140 * m * 2-1) is included, and the UE's SCS is 15 * m KHz, and the number of paging cycles in a paging cycle is equal to one-quarter of a paging cycle, the symbol level offset ranges from 0 to (140 * m * 4-1) is included, and the UE's SCS is 15 * m KHz, and the number of total paging frames in a paging cycle is equal to one-eighth of the paging cycle, the symbol level offset ranges from 0 to (140 * m *8-1) and the UE's SCS is 15 * m KHz, and the number of total paging frames in a paging cycle is equal to 1 / 16 of the paging cycle, the symbol level offset ranges from 0 to (140 * m * In some other implementations, n may be one of 0, 1, 2, 3, 4, 5, or 6, and thus m may be one of 1, 2, 4, 8, 16, 32, or 64.
[0103] In various embodiments, the symbol level offset list is a list including one or more symbol level offsets, and the number of candidate values of the symbol level offset list is the following: the number of PEIs in one frame (e.g., PEIs in one frame means that the PEIs correspond to the same reference frame, or PEIs in one frame means that the PEIs correspond to the same reference point), the number of POs associated with one PEI,
number
[0104] In some implementations, the number of candidate values in the symbol level offset list may be equal to the number of PEIs in one frame or equal to the number of PEIs corresponding to one reference point.
[0105] In some other implementations, the number of candidate values in the symbol-level offset list is limited to a ceiling value

[0107] In some other implementations, the first PDCCH monitoring opportunity number of the PEI corresponding to the UE that monitored the (i_s+1)th PO is
number
[0108] In some other implementations, the number of candidate values of the symbol level offset may be equal to the number of POs associated with one PEI.
[0109] In some other implementations, the symbol level offset corresponding to the UE that monitored the (i_PO+1)th PO may be the (i_PO+1)th value in the symbol level offset list.
[0110] In some other implementations, the first PDCCH monitoring opportunity number of the PEI corresponding to the UE that monitored the (i_PO+1)th PO may be the (i_PO+1)th value in the symbol level offset list.
[0111] In some other implementations, the range of the symbol level offset is determined by at least one of the following: a subcarrier space (SCS) of the UE; and / or N, the number of total paging frames in a paging cycle.
[0112] In some other implementations, the range of the symbol level offset is determined by the SCS of the UE. * In response to the 140 m KHz symbol level offset, the range is from 0 to (140 * m-1), where m=2 n where n is a non-negative integer. For example, the symbol level offset may be determined by the following: when the SCS is 15 KHz, the symbol level offset range may be 0 to 139 symbols, when the SCS is 30 KHz, the symbol level offset range may be 0 to 279 symbols, when the SCS is 60 KHz, the symbol level offset range may be 0 to 559 symbols, and / or when the SCS is 120 KHz, the symbol level offset range may be 0 to 1,119 symbols.
[0113] In some other implementations, the reference point is the start of a reference frame, so that the location of the reference point may be accurate to the radio frame level. Based on the reference point, the symbol level offset further positions the PEI at the symbol level, and the first monitoring opportunity of the PEI may be any symbol within the reference frame.
[0114] In some other implementations, the range of the symbol level offset is determined by the SCS of the UE and the number of total paging frames in a paging cycle. * m KHz, and the number of total paging frames in a paging cycle is equal to the paging cycle, the symbol level offset ranges from 0 to (140 *m-1), where m=2 n where n is a non-negative integer. The SCS of the UE is 15. * m KHz, and the number of total paging frames in a paging cycle is equal to half the paging cycle, the symbol level offset ranges from 0 to (140 * m * 2-1) is judged to include up to 15 * m KHz, and the number of paging cycles in a paging cycle is equal to one-quarter of a paging cycle, the symbol level offset ranges from 0 to (140 * m * 4-1) is judged to include up to 15 * m KHz, and the number of total paging frames in a paging cycle is equal to one-eighth of the paging cycle, the symbol level offset ranges from 0 to (140 * m * 8-1) and / or the UE's SCS is 15 * m KHz, and the number of total paging frames in a paging cycle is equal to 1 / 16 of the paging cycle, the symbol level offset ranges from 0 to (140 * m * 16-1) will be considered to be included.
[0115] For example, the symbol level offset may be determined as follows: when SCS is 15 KHz and N=T, the symbol level offset range may be 0 to 139 symbols; when SCS is 30 KHz and N=T, or SCS is 15 KHz and N=T / 2, the symbol level offset range may be 0 to 279 symbols; when SCS is 60 KHz and N=T, or SCS is 30 KHz and N=T / 2, or SCS is 15 KHz and N=T / 4, the symbol level offset range may be 0 to 559 symbols; when SCS is 120 KHz and N=T, or SCS is 60 KHz and N=T / 2, or SCS is 30 KHz and N=T / 4, or SCS is 15 KHz and N=T / 8, the symbol level offset range may be 0 to 1,119 symbols. When SCS is 120KHz and N=T / 2, or SCS is 60KHz and N=T / 4, or SCS is 30KHz and N=T / 8, or SCS is 15KHz and N=T / 16, the symbol level offset range can be 0 to 2,239 symbols, when SCS is 120KHz and N=T / 4, or SCS is 60KHz and N=T / 8, or SCS is 30KHz and N=T / 16. When SCS is 120KHz and N=T / 8, or when SCS is 60KHz and N=T / 16, the symbol level offset range can be 0 to 8,959 symbols, and / or when SCS is 120KHz and N=T / 16, the symbol level offset range can be 0 to 17,919 symbols.
[0116] In some other implementations, N is the number of total paging frames in a paging cycle and T is the paging cycle. For different values of N, the distance between two PFs may be different.
[0117] In some other implementations, the maximum value of the symbol level offset may be equal to the maximum number of symbols between the two PFs.
[0118] In various embodiments, the transmit power of the PEI is associated with at least one of the following: an upper layer parameter, a transmit power of a secondary synchronization signal (SSS), or a transmit power of a paging PDCCH.
[0119] In some implementations, the transmit power of the PEI is determined by a ratio of the energy per resource element (EPRE) of the demodulation reference signal (DMRS) of the PEI to the SSS EPRE within −X dB to X dB (X is a positive integer) in response to the upper layer parameters being configured, and / or in response to the upper layer parameters not being configured.
[0120] In some other implementations, the transmit power of the PEI is determined by a ratio of the DMRS EPRE of the PEI to the DMRS EPRE of the paging PDCCH within −YdB to YdB, where Y is a positive integer.
[0121] In some other implementations, the transmit power of the PEI may be configured by higher layer parameters.
[0122] In some other implementations, the transmit power of the PEI may be determined by the transmit power of the SSS. For example, the ratio of the energy per resource element (EPRE) of the demodulation reference signal (DMRS) of the PEI to the SSS EPRE is within -XdB to XdB (e.g., X=8). Here, in various embodiments in the present disclosure, dB may be referred to as decibel and equal to one-tenth of a Bel (B), which represents the ratio of two values of a power or root / power quantity on a logarithmic scale.
[0123] In some other implementations, the transmit power of the PEI, if configured, may be configured by upper layer parameters, and if not, the ratio of the DMRS EPRE to the SSS EPRE of the PEI is within -XdB to XdB (e.g., X=8).
[0124] In some other implementations, the DMRS EPRE of the PEI may be equal to the DMRS EPRE of the paging PDCCH, and in some other embodiments, the ratio of the DMRS EPRE of the PEI to the DMRS EPRE of the paging PDCCH is within −X dB to X dB (e.g., X=3).
