Description

Technical Field

[0001] This invention relates to the field of communications, and more particularly to an information configuration method, apparatus, device, storage medium, and product. Background Technology

[0002] PRACH (Physical Random Access Channel) is an uplink common signal whose main functions are to initiate access and complete uplink timing synchronization between different terminal devices. PRACH configuration is based on SIB1 (System Information Block) indication. To save network energy, existing technologies employ a mechanism of triggering SIB1 on demand. The main purpose is to prevent SIB1 transmission by default in NES (Network Energy Saving) cell scenarios. When a terminal device requires it, it can enable the network device to transmit SIB1 in the NES cell by sending an uplink wake-up signal (PRACH signal). Although this method can save network energy, existing technologies still have the following problems:

[0003] 1. After sending the uplink wake-up signal and acquiring SIB1, the terminal device typically also sends a PRACH signal and performs random access, and / or establishes or restores RRC (Radio Resource Control) protocol. Directly using the existing mechanism would result in low transmission efficiency and high power consumption for the PRACH signal.

When the PRACH signal corresponds to multiple NES cells, the existing technology does not specify how to determine the transmission power when sending the PRACH signal, and the behavior of the terminal equipment in determining the uplink wake-up signal transmission power is uncertain; Summary of the Invention

[0091] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0092] The PRACH configuration is based on the SIB1 indicator, including fields such as prach-Configuration Index (time domain start position and time domain resource usage indicator), msg1-Frequency Start (frequency domain start position indicator), msg1-FDM (frequency domain resource usage indicator), and ssb-per RACH-Occasion And CB-Preambles Per SSB (SSB mapping relationship). Among these:

[0093] 1) The prach-Configuration Index indicates the time-domain resource configuration of PRACH, which can be obtained by querying a pre-defined table in the prior art;

[0094] 2) msg1-Frequency Start and msg1-FDM indicate the frequency domain start position of the PRACH resource and the number of frequency domain resources occupied, respectively;

[0095] 3) SSB-per RACH-Occasion And CB-Preambles Per SSB indicates the mapping relationship between SSB and PRACH resources;

[0096] It is understandable that PRACH resources corresponding to different SSB indices have different transmission filtering parameters (or spatial information, beam direction, etc.); different PRACH resources corresponding to the same SSB index have the same transmission filtering parameters. For example... Figure 1 As shown, Figure 1 This is a schematic diagram illustrating the determination of PRACH transmission resources provided by existing technology. Based on the above fields, the transmission resources of PRACH can be determined.

[0097] Additionally, for special-purpose PRACH, their dedicated RO (PRACH transmission occasion) / Preamble resources can be configured using extra fields. These fields include:

[0098] 1) si-Request Period: This field indicates the length of the dedicated PRACH resource transmission period, specifically, it is 1 / 2 / 4 / 6... times the PRACH association period;

[0099] 2) ra-Association Period Index: This field indicates the specific location of the association period of a dedicated PRACH resource within each dedicated PRACH resource transmission period, in units of PRACH association periods.

[0100] 3) ra-ssb-Occasion Mask Index: This field indicates the specific location of the RO corresponding to the dedicated PRACH resource in each PRACH association cycle;

[0101] 4) ra-Preamble Start Index: This field indicates the specific location of the Preamable corresponding to the dedicated PRACH resource in the RO of each dedicated PRACH resource.

[0102] In existing technologies, when a terminal device sends a PRACH signal, it is also necessary to determine the transmission power, which can be configured using the following formula:

[0103] P PRACH =min{P CMAX P PRACH，target +PL}dBm (1);

[0104] Among them, P CMAX PL is the maximum transmit power of the terminal device; PL is the path loss value, which is measured by the terminal device based on the SSB (Synchronization Signal / PBCH Block). The network device indicates the transmit power of the SSB in the system message (also called SIB1), and the terminal device calculates the path loss based on the measured receive-side power; P PRACH，target The target power for PRACH is determined according to the following formula:

[0105] P PRACH，target =preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER-1)*PREAMBLE_POWER_RAMPING_STEP (2);

[0106] Here, `preambleReceivedTargetPower` is the network-side desired PRACH receive power, the specific value of which is configured by the network device to the terminal device through system information; `DELTA_PREAMBLE` is the power offset value between the current transmitted PRACH signal format and the reference PRACH format (such as PRACH format 0), which can be determined according to the network-side configuration; `PREAMBLE_POWER_RAMPING_COUNTER` is a power ramp-up counter. For the initial transmission, it has a value of 1, and it increments by 1 with each retransmission; the power ramp-up step size `PREAMBLE_POWER_RAMPING_STEP` is indicated by the `power Ramping Step` field (configured in system information).

[0107] After sending the PRACH signal, the terminal device needs to receive feedback information. Within a configured time window, the terminal device continuously monitors and schedules the DCI (Downlink Control Information) of the RAR (Random Access Response). The length of this time window is pre-configured by the network device; specifically, it is determined by the parameter ra-Response Window, which is configured in SIB1.

[0108] Current technology provides a mechanism for triggering SIB1 on demand. Its main purpose is to prevent SIB1 from being sent under normal circumstances in NES cell (Network Energy Saving Cell) scenarios, thereby saving network energy consumption. Figure 2 As shown, Figure 2 This is a schematic diagram of a terminal device sending an uplink trigger signal according to existing technology. When the terminal device needs it, it can enable the network device to send SIB1 in the NES cell by sending an uplink trigger signal (PRACH signal). Specifically, the configuration information required to send the uplink trigger signal may be obtained in advance by the terminal device (from another cell).

[0109] The existing technology discusses the configuration granularity of the uplink trigger signal, and currently there are two possible lower-level branches:

[0110] 1) The uplink trigger signal is a PRACH resource dedicated to a certain NES cell. That is, the uplink trigger signal sent on this PRACH resource only triggers SIB1 of a specific NES cell.

[0111] 2) The uplink trigger signal is the PRACH resource corresponding to multiple NES cells. That is, the uplink trigger signal sent on the PRACH resource can trigger the SIB1 of multiple NES cells.

[0112] For the two branches of uplink trigger signal configuration granularity mentioned above, one possible combination is to configure an NES cell list, which can contain one or more NES cell identifiers. The terminal can implicitly determine the configuration granularity based on the number of NES cell identifiers in the list.

[0113] While the above methods can save network energy, existing technologies still have some problems, specifically including:

[0114] 1. After sending the uplink wake-up signal and acquiring SIB1, the terminal device will typically also send...

[0115] The PRACH signal is used for random access and / or the establishment or recovery of RRC. Directly using the existing mechanism (i.e., the counter starts counting from 1, and the relevant power components are determined according to configuration parameters) results in low transmission efficiency and high energy consumption for the PRACH signal.

[0116] 2. When the PRACH signal corresponds to multiple NES cells, the existing technology does not standardize the transmission...

[0117] How to determine the transmit power when using the PRACH signal, and the behavior of the terminal device in determining the transmit power of the uplink wake-up signal are uncertain.

[0118] Based on this, the present invention designs and solves the technical problems of the specific content design of the feedback information corresponding to the uplink wake-up signal (first random access signal) in the OD-SIB1 process, the determination of the transmission power of the PRACH signal (second random access signal) used for random access and / or RRC establishment or recovery, and how to determine the transmission power / receive window length of the uplink wake-up signal in the scenario of multiple NES cells corresponding to the uplink wake-up signal.

[0119] The terminal equipment described in this embodiment of the invention can refer to an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device. The access terminal can be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, IoT device, satellite handheld terminal, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device, wearable device, terminal equipment in a 5G network, or terminal equipment in a future evolved network, etc.

[0120] The network device described in this embodiment of the invention may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a radio controller in a Cloud Radio Access Network (CRAN), or the network device may be a relay station, access point, vehicle-mounted device, wearable device, hub, switch, bridge, router, or network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0121] See Figure 3 , Figure 3 This is a flowchart of a first information configuration method provided in an embodiment of the present invention. The first information configuration method is applied to a terminal device and includes:

[0122] S1. Determine the first transmit power of the first random access signal; wherein, the first random access signal is used to request the first system information block SIB1;

[0123] S2. Determine the second transmission power of the second random access signal based on the first transmission power; the second random access signal is used for random access and / or for establishing / restoring an RRC connection.

[0124] For example, the first random access signal is the uplink wake-up signal (PRACH signal), and the second random access signal is the PRACH signal used for establishing or restoring random access and / or RRC. After determining the first transmit power, the terminal device sends the first random access signal based on the first transmit power to request the first system information block SIB1. After determining the first transmit power, the terminal device determines the second transmit power based on the parameter configuration of the first transmit power. Specifically, there are two possible determination methods: the first is to fully reuse the parameter configuration of the first random access signal, and the second is to partially reuse the parameter configuration of the first random access signal.

[0125] In this embodiment of the invention, the terminal device determines the power configuration for sending the uplink wake-up signal, thereby improving signal transmission efficiency and reducing device power consumption. In addition, by adopting the above two methods for determining the second power, the coverage performance of the signal can be further improved, redundant power boosting steps can be reduced, and the reliability and communication efficiency of the communication link can be improved.

[0126] In the first embodiment, the second transmission power is equal to the first transmission power.

[0127] For example, see Figure 4 , Figure 4 This is a schematic diagram of the transmission of the first random access signal and the second random access signal provided in an embodiment of the present invention. At this time, the second random access signal reuses all the parameter configurations of the first random access signal, and the second transmission power is equal to the first transmission power.

[0128] In the second embodiment, the first transmit power is associated with a first parameter, and the second transmit power is determined based on the first parameter; wherein the first parameter includes at least one of the following:

[0129] 1) First target received power P R1 ;

[0130] 2) First power boost value P T1 ;

[0131] 3) First path loss value PL1;

[0132] 4) First target received power P R1 The sum of the first path loss value PL1.

[0133] It is understood that the first transmission power is associated with the first parameter, or it can be replaced by the first transmission power including the first parameter, or the first transmission power being determined based on the first parameter;

[0134] In one possible implementation, the second transmission power can be determined in the following manner:

[0135] Second transmission power = min{P CMAX P R2 +P T2 +PL2+Δ}dBm (3);

[0136] Among them, P R2 For the second target received power, P T2 PL2 is the second power boost value, PL2 is the second path loss value, and Δ is the power offset value between the format of the second random access signal and the reference PRACH format (e.g., PRACH format 0).

[0137] For example, the second transmit power P2 is determined based on the above four first parameters, and the value of one or more of the four first parameters is equal to the value of the corresponding second parameter in the first transmit power. The value of the first parameter may include one or more of the following seven determination methods:

[0138] 1. The first parameter is the first target received power P. R1 The second parameter is the second target received power P. R2 At this point, the following conditions are met:

[0139] P R2 =P R1 (4);

[0140] 2. The first parameter is the first power boost value P. T1 The second parameter is the first power boost value P. T2 At this point, the following conditions are met:

[0141] P T2 =P T1 (5);

[0142] 3. The first parameter is the first path loss value PL1, and the second parameter is the second path loss value PL2. At this time, the following conditions are met:

[0143] PL2 = PL1(6);

[0144] 4. The first parameter is P R1 The sum of PL1, with the second parameter being P. R2 The sum of PL2 and PL2 at this time satisfies:

[0145] P R2 +PL2=P R1 +PL1(7);

[0146] 5. The first parameter includes P R1 and P T1 The second parameter includes P R2 and P T2 At this point, the following conditions are met:

[0147] P R2 +P T2 =P R1 +P T1 (8);

[0148] 6. The first parameter includes P T1 And PL1, the second parameter includes P T2 And PL2, at this time, the following conditions are met:

[0149] P T2 +PL2=P T1 +PL1 (9);

[0150] 7. The first parameter includes P R1 P T1 And PL1, the second parameter includes P R2 P T2 And PL2, at this time, the following conditions are met:

[0151] P R2 +P T2 +PL2=P R1 +P T1 +PL1 (10).

[0152] Furthermore, the first power boost value P T1 Includes at least one of the following:

[0153] 2.1) First power boost step size P step1 ;

[0154] That is, the second power boost value P T2 It may include a second power boost step size P step2 At this point, the following conditions are met:

[0155] P step2 =P step1 (11);

[0156] 2.2) First count value P count1 ;

[0157] That is, the second power boost value P T2 It may include a second count value P count2 At this point, the following conditions are met:

[0158] P count2 =P count1 (12);

[0159] 2.3) First product K1; the first product is the first difference and the first power boost step size P. step1 The product of the first difference is the first count value P. count1 The difference between the product and the set constant D, i.e., the first product K1, satisfies:

[0160] K1=(P count1 -D)*P step1 (13);

[0161] That is, the second power boost value P T2 It can include the second product K2, in which case the following condition is met:

[0162] K2 = K1 (14).

[0163] In one possible implementation, the synchronization signals and Physical Broadcast Channel Block (SSB) indices corresponding to the first random access signal and the second random access signal are the same. That is, the spatial information of the first random access signal and the second random access signal is identical.

[0164] The beneficial effects of the above branches are: clarifying the spatial configuration when transmitting the second random access signal; further improving transmission efficiency and reducing transmission power consumption;

[0165] Specifically, the method further includes:

[0166] S111, Send the first random access signal in the first time unit;

[0167] S112. Send the second random access signal in the second time unit;

[0168] The interval between the first time unit and the second time unit is less than the first time interval.

[0169] For example, the first time interval is a predefined value, or the network device sends time information, which includes the first time interval. It is understood that the time information may belong to the configuration information, or the time information and the configuration information may be independent of each other.

[0170] In one possible implementation, the terminal device starts a first timer in the first time unit / the next time unit after the first time unit, that is, the time unit after the time unit in which the first random access signal is sent / the next time unit after the time unit in which the first random access signal is sent, and the duration of the first timer is the first time interval.

[0171] In one possible implementation, the interval between the first time unit and the second time unit is less than the first time interval. Alternatively, it can be stated that the first timer is running or has not timed out when the second time unit or when the second random access signal is sent.

[0172] The beneficial effect of the above-mentioned branch is that the correlation between the transmission power of the first random access signal and the second random access signal in this invention only applies within a predefined / network configured time period. This further enhances the time effectiveness of terminal devices using previous transmission power schemes;

[0173] It is understood that the unit of the above time unit can be a time slot, or an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a radio frame, a half frame, a millisecond (ms), a second (s), or other time granularities. This invention does not impose any specific limitations.

[0174] Specifically, the first SIB1 is non-broadcast system information, or the first SIB1 is system information triggered on demand.

[0175] For example, when the first SIB1 is a non-broadcast system message, or when the first SIB1 is an on-demand triggered system message, the network device sends the first SIB1 to the corresponding terminal device.

[0176] Specifically, the random access includes at least one of four-step random access, two-step random access, contention-based random access, and non-contention-based random access.

[0177] It should be noted that the random access procedures for four-step random access, two-step random access, contention-based random access, and non-contention-based random access can refer to existing technologies, and this invention does not impose specific limitations on them.

[0178] Specifically, the method further includes:

[0179] S101. Receive configuration information; wherein, the configuration information includes a second parameter corresponding one-to-one with N first cells, the first random access signal is associated with the N first cells, and N is a positive integer greater than 1;

[0180] S102. Determine the first parameter based on N second parameters.

[0181] For example, the configuration information may be sent by a network device, where the first cell is a power-saving (NES) cell, and the SIB1 of the N first cells is non-broadcast system information, or the SIB1 of the N first cells is on-demand triggered system information. The configuration of the first random access signal is associated with the N first cells, or the configuration of the first random access signal is associated with the PCI (Physical Cell Identifier) ​​of the N first cells. The number of first cells corresponds one-to-one with the second parameter. For example, when N=3, it includes three first cells: NES1, NES2, and NES3. Each first cell corresponds to one second parameter, meaning there are also three second parameters. The first parameter is determined based on these three second parameters.

[0182] Specifically, in step S101, receiving configuration information includes: receiving the configuration information in the second cell; wherein, the SIB1 of the second cell is broadcast system information, and the second cell is a non-energy-saving cell.

[0183] Furthermore, the embodiments of the present invention provide the following three methods for determining the first parameter:

[0184] 1) In a first embodiment, the first parameter is the maximum value among the N second parameters.

[0185] For example, in this embodiment, the first parameter includes a first target received power, and the second parameter includes a second target received power; or, the first parameter includes a first power boost value, and the second parameter includes a second power boost value. Taking the case where the first parameter includes the first power boost value as an example (the same applies when the first parameter includes the first target received power), we can then know the second power boost values ​​corresponding to the three first cells NES1, NES2, and NES3 respectively. If the second power boost value corresponding to NES1 is the largest, then the first power boost value is the second power boost value corresponding to NES1, that is, the first parameter is the second power boost value corresponding to NES1.

[0186] Furthermore, the first parameter can also be the minimum value among the N second parameters. For example, if the second power boost value corresponding to NES2 is the smallest, then the first power boost value is the second power boost value corresponding to NES2, that is, the first parameter is the second power boost value corresponding to NES2.

[0187] 2) In the second embodiment, the first parameter includes a first path loss value, and the second parameter includes SSB transmit power; N candidate path loss values ​​corresponding to the first cell are determined based on the N SSB transmit powers, and the maximum candidate path loss value is determined from the N candidate path loss values ​​as the first path loss value.

[0188] For example, the path loss is determined by the terminal device based on the power of the received SSB and the transmission power of the SSB. The terminal device first obtains the candidate path loss values ​​corresponding to the three first cells NES1, NES2 and NES3 respectively. If the candidate path loss value of NES2 is the largest at this time, then the first path loss value is the candidate path loss value of NES2, that is, the first parameter is the candidate path loss value of NES2.

[0189] Furthermore, the minimum candidate path loss value can be determined from the N candidate path loss values ​​as the first path loss value. For example, if the candidate path loss value of NES1 is the minimum, then the first path loss value is the candidate path loss value of NES1, that is, the first parameter is the candidate path loss value of NES1.

[0190] 3) In a third embodiment, the first parameter includes a first power boost value; the first power boost value is the power boost value of the first cell corresponding to the maximum value among the N second parameters; or, the first power boost value is the power boost value of the first cell corresponding to the maximum value among the N third parameters, wherein the third parameters are determined based on the second parameters.

[0191] For example, the second parameter includes the second target received power. First, the second target received power corresponding to the three first cells NES1, NES2 and NES3 is obtained respectively. If the second target received power of NES3 is the largest at this time, the power boost value of NES3 is obtained. At this time, the first power boost value is the power boost value of NES3, that is, the first parameter is the power boost value of NES3.

[0192] Furthermore, the first power boost value can also be the power boost value of the first cell corresponding to the minimum value among the N second parameters. If the second target received power of NES1 is the minimum at this time, the power boost value of NES1 is obtained, and the first power boost value is the power boost value of NES1, that is, the first parameter is the power boost value of NES1.

[0193] For example, the third parameter includes at least one of the following: the sum of the second target received power and the second path loss value; the second path loss value. Based on the third parameter, the second parameters corresponding to all first cells can be determined, and then the first parameter is obtained by referring to the above method. Further, the second parameter includes the SSB transmit power corresponding to N first cells: the second path loss value corresponding to N first cells is determined based on the N SSB transmit powers. Even further, the first power boost value can also be the power boost value of the first cell corresponding to the minimum value among the N third parameters.

[0194] In this embodiment of the invention, the first parameter can be determined based on the second parameter. Using the "maximum value" method can improve the transmission efficiency and performance of the uplink wake-up signal. Using the "minimum value" method can reduce the power consumption of the terminal side when sending the uplink wake-up signal, while also reducing interference to the uplink transmission of other terminals.

[0195] It is worth noting that there is also a case where N=1 in the embodiments of the present invention. In this case, the above configuration information only includes a second parameter corresponding to the first cell. Since there is only one first cell, there is no need to use the "maximum value" or "minimum value" method to determine the first parameter. The first parameter can be directly equal to the second parameter.

[0196] Specifically, the configuration information also includes N second time windows corresponding one-to-one with the first cells, and the method further includes:

[0197] S201. Determine the first time window based on N second time windows;

[0198] S202, Receive a first random access response (RAR) within a first time window, wherein the first RAR is associated with the first random access signal.

[0199] For example, see Figure 5 , Figure 5 This is a schematic diagram illustrating the transmission of the first random access response provided in an embodiment of the present invention. The terminal device sends a first random access signal to the network device. After receiving the first random access signal, the network device returns a first random access response (RAR) to inform the terminal device that it has received the first random access signal. During this process, the terminal device needs to receive the first random access response within a first time window, which is determined based on N second time windows in the configuration information.

[0200] Specifically, in step S201, determining the first time window based on N second time windows includes at least one of the following:

[0201] 1) The first time window is the maximum value among N second time windows;

[0202] 2) The length of the first time window is the second time window of the first cell corresponding to the maximum value among the N fourth parameters; wherein, the fourth parameters include at least one of the following: second target received power; second power boost value.

[0203] For example, the second time window is the reception time window in the first cell. Taking the second target received power as an example, assuming there are still three first cells, NES1, NES2, and NES3, the second target received power corresponding to NES1, NES2, and NES3 is first obtained. If the second target received power of NES3 is the largest at this time, the second time window corresponding to NES3 is obtained, and the first time window is the second time window corresponding to NES3. Further, the length of the first time window can also be the second time window of the first cell corresponding to the minimum value among the N fourth parameters.

[0204] In this embodiment of the invention, the first time window can be determined based on the second time window. Using the "maximum value" determination method can improve the transmission efficiency and performance of RAR. Using the "minimum value" determination method can reduce the power consumption of the terminal side detecting RAR.

[0205] Compared to existing technologies, the information configuration method disclosed in this invention allows the terminal device to determine the power configuration for sending uplink wake-up signals, thereby improving signal transmission efficiency and reducing device power consumption. Furthermore, during random access, the terminal device can reuse all or part of the power configuration methods of previous uplink wake-up signals, further improving signal coverage performance, reducing redundant power boosting steps, and thus enhancing the reliability and efficiency of the communication link. Additionally, the terminal device determines the parameter configuration for sending uplink wake-up signals through configuration information sent by the network device, thereby improving signal transmission efficiency and reducing device power consumption.

[0208] Specifically, the synchronization signals and physical broadcast channel block (SSB) indices corresponding to the first random access signal and the second random access signal are the same.

[0209] Specifically, the network device receives the first random access signal in a first time unit and the second random access signal in a second time unit; wherein the interval between the first time unit and the second time unit is less than the first time interval.

[0210] Specifically, the configuration information includes a second parameter that corresponds one-to-one with each of the N first cells, wherein the first random access signal is associated with the N first cells, and N is a positive integer greater than 1; the second parameter includes one of the following:

[0211] Second target received power;

[0212] Second power boost value;

[0215] Specifically, the method further includes: sending a first random access response (RAR) within a first time window, the first RAR being associated with the first random access signal.
