[0001] Cross-reference to Related Applications

[0002] The present disclosure claims priority from Chinese Patent Application No. 202411339639.2 filed on September 25, 2024 in China, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0004] A physical random access channel (PRACH) is an uplink common signal, and its main functions are to initiate access and complete uplink timing synchronization between different terminal devices. PRACH configuration is based on system information block (SIB1) indication. In order to save network energy, the related technology adopts an on-demand triggering SIB1 mechanism, the main purpose of which is to not send SIB1 by default in a network energy saving (NES) cell scenario. When a terminal device has a demand, it can enable the network device to send SIB1 in the NES cell by sending an uplink wake-up signal (PRACH signal). Although this approach can save network energy, the related technology still has the following problems:

[0005] 1. After sending the uplink wake-up signal and obtaining SIB1, the terminal device will usually send a PRACH signal and perform random access, and / or radio resource control (RRC) establishment or recovery. If the existing mechanism is directly followed, the transmission efficiency of the PRACH signal will be low and the energy consumption will be high.

[0006] 2. When the PRACH signal corresponds to multiple NES cells, the related technology does not specify how to determine the transmission power when sending the PRACH signal, and the behavior of the terminal device in determining the uplink wake-up signal transmission power is uncertain.

[0093] The technical solutions in the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present disclosure.

[0094] The PRACH configuration is indicated based on SIB1, including time domain starting position and time domain resource indication (prach-Configuration Index), frequency domain starting position indication (msg1-Frequency Start), frequency domain resource indication (msg1-FDM), and SSB mapping relationship (ssb-per RACH-Occasion And CB-Preambles Per SSB) fields. Among them:

[0095] 1) prach-Configuration Index indicates the time domain resource configuration of PRACH, which can be obtained by querying the preset table in the related art;

[0096] 2) msg1-Frequency Start and msg1-FDM respectively indicate the frequency domain starting position of the PRACH resource and the number of occupied frequency domain resources;

[0097] 3) ssb-per RACH-Occasion And CB-Preambles Per SSB indicates the mapping relationship between SSB (Synchronization Signal / PBCH Block) and PRACH resource;

[0098] It can be understood that the transmission filtering parameters (or spatial information, beam direction, etc.) of the PRACH resource corresponding to different SSB indexes are different; the transmission filtering parameters of different PRACH resources corresponding to the same SSB index are the same. As shown in FIG. 1, FIG. 1 is a determination schematic diagram of PRACH transmission resource provided by the related art, based on the above fields, the transmission resource of PRACH can be determined.

[0099] In addition, for PRACH with special purpose, the dedicated random access channel occasion (RO) / preamble resource can be configured by means of additional fields, and the field configuration includes:

[0100] 1) si-Request Period, which indicates the length of the dedicated PRACH resource transmission period, specifically, it is 1 / 2 / 4 / 6… times of the PRACH association period;

[0101] 2) ra-Association Period Index, which indicates the specific position of the dedicated PRACH resource in each dedicated PRACH resource transmission period in the association period, such as the unit is PRACH association period;

[0102] 3) ra-ssb-Occasion Mask Index, which indicates the specific location of the RO corresponding to the dedicated PRACH resource in each PRACH associated period;

[0103] 4) ra-Preamble Start Index, which indicates the specific location of the Preamable corresponding to the dedicated PRACH resource in the RO of each dedicated PRACH resource.

[0104] In the related art, when the terminal device transmits the PRACH signal, the transmission power also needs to be determined, which can be configured by the following formula: P PRACH = min{P CMAX , P PRACH,target + PL} dBm (1).

[0105] Wherein, P CMAX is the maximum transmission power of the terminal device; PL is the path loss value, which is obtained by the terminal device based on SSB measurement, and the network device indicates the transmission power of SSB in the system message block (also called SIB1), and the terminal device calculates the path loss based on the measured receiving side power; P PRACH,target is the target power of PRACH, which is determined according to the following formula: P PRACH,target = preambleReceivedTargetPower + DELTA_PREAMBLE + (PREAMBLE_POWER_RAMPING_COUNTER-1)*PREAMBLE_POWER_RAMPING_STEP (2).

[0106] Wherein, preambleReceivedTargetPower is the PRACH receiving power expected by the network side, and the specific value is configured to the terminal device by the network device through the system information; DELTA_PREAMBLE is the power offset value between the format of the currently transmitted PRACH signal and the reference PRACH format (such as PRACH format 0), and the specific value can be determined according to the network side configuration; PREAMBLE_POWER_RAMPING_COUNTER is the counter of power ramping. For initial transmission, its value is 1, and for retransmission, it is increased by 1 each time; the power ramping step PREAMBLE_POWER_RAMPING_STEP is indicated by the field power Ramping Step (configured in the system information).

[0107] After the terminal device sends the PRACH signal, feedback information needs to be received. The terminal device continues to detect the downlink control information (DCI) scheduling the random access response (RAR) within the configured time window. The length of the time window is pre-configured by the network device, specifically, the length of the time window is determined by the parameter ra-Response Window, which is configured in SIB1.

[0108] The related art currently provides a mechanism for triggering SIB1 on demand, the main purpose of which is to not send SIB1 under normal circumstances in a network energy saving cell (NES cell) scenario, thereby saving network energy consumption; as shown in FIG. 2, which is a schematic diagram of a terminal device sending an uplink trigger signal provided by the related art, when the terminal device has a demand, 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 for sending the uplink trigger signal can be pre-acquired by the terminal device (from another cell).

[0109] The related art discusses the configuration granularity of the uplink trigger signal, and there are two possible sub-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 the PRACH resource only triggers the SIB1 of a specific NES cell;

[0111] 2) The uplink trigger signal is a 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 configuration granularity branches of the uplink trigger signal described above, a possible combination is to configure a list of NES cells, which can have one or more identifiers of NES cells. The terminal device can implicitly determine the configuration granularity according to the number of NES cell identifiers in the list.

[0113] Although the above-mentioned way can save network energy consumption, the related art still has some problems, specifically, including:

[0114] 1. After sending the uplink wake-up signal and obtaining SIB1, the terminal device will usually also send a PRACH signal and perform random access, and / or RRC establishment or restoration. Directly following the existing mechanism (i.e., the counter starts counting from the initial value 1, and the relevant power component is determined according to the configuration parameters), the transmission efficiency of the PRACH signal is low and the energy consumption is high.

[0115] 2. When the PRACH signal corresponds to multiple NES cells, the related technology does not specify how to determine the transmission power when sending the PRACH signal, and the behavior of the terminal device in determining the uplink wake-up signal transmission power is uncertain.

[0116] Based on this, the present disclosure designs and solves the technical problems of the specific content design of the uplink wake-up signal (first random access signal) corresponding to the feedback information in the on-demand SIB1 (OD-SIB1) process, the determination of the transmission power of the PRACH signal (second random access signal) used for subsequent random access and / or RRC establishment or restoration, and how to determine the transmission power / acceptance window length of the uplink wake-up signal in the scenario of the uplink wake-up signal corresponding to multiple NES cells.

[0117] The terminal device described in the embodiments of the present disclosure can refer to an access terminal, a user equipment (User Equipment, UE), a user unit, a user station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user device. The access terminal can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, an Internet of Things (IoT) device, a satellite handheld terminal, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a 5th Generation Mobile Communication Technology (5G) network or a terminal device in a future evolution network, etc.

[0118] The network device in the embodiments of the present disclosure can 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 a new radio (NR) system, or a wireless controller in a cloud radio access network (CRAN), or a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved public land mobile network (PLMN), and the like.

[0119] Referring to FIG. 3, FIG. 3 is a flowchart of a first information configuration method provided by the embodiments of the present disclosure, the first information configuration method is applied to a terminal device, and the first information configuration method comprises the following steps:

[0120] S1, determining a first transmission power of a first random access signal; wherein the first random access signal is used to request a first system information block (SIB1);

[0121] S2, determining a second transmission power of a second random access signal according to the first transmission power; the second random access signal is used for random access and / or establishing / resuming an RRC connection.

[0122] For example, the first random access signal is a PRACH signal, and the second random access signal is a PRACH signal used for random access and / or establishing or resuming an RRC. After determining the first transmission power, the terminal device transmits the first random access signal based on the first transmission power, so as to request the first system information block (SIB1). After determining the first transmission power, the terminal device determines the second transmission power based on the parameter configuration of the first transmission power. Specifically, there can be two possible determination methods: the first method can completely reuse the parameter configuration of the first random access signal, and the second method can partially reuse the parameter configuration of the first random access signal.

[0123] In the embodiments of the present disclosure, the terminal device determines the power configuration of the PRACH signal, so as to improve the signal transmission efficiency and reduce the device energy consumption. In addition, the two second power determination methods can further improve the coverage performance of the signal, reduce the redundant power lifting step, and further improve the reliability and communication efficiency of the communication link.

[0124] In a first implementation, the second transmission power is equal to the first transmission power.

[0125] For example, referring to FIG. 4, which is a schematic diagram of transmission of the first random access signal and the second random access signal according to an embodiment of the present disclosure, in this case, the second random access signal fully multiplexes the parameter configuration of the first random access signal, and the second transmission power is equal to the first transmission power.

[0126] In a second implementation, the first transmission power is associated with a first parameter, and the second transmission power is determined according to the first parameter; wherein the first parameter comprises at least one of the following:

[0127] 1) a first target received power P R1 ;

[0128] 2) a first power boost value P T1 ;

[0129] 3) a first path loss value PL1;

[0130] 4) a sum of the first target received power P R1 and the first path loss value PL1.

[0131] It can be understood that the first transmission power is associated with the first parameter, and alternatively, the first transmission power comprises the first parameter, or the first transmission power is determined according to the first parameter.

[0132] In a possible implementation, the second transmission power can be determined in the following manner: second transmission power = min{P CMAX ,P R2 + P σ2 + PL2+ Δ} dBm (3).

[0133] wherein P R2 is a second target received power, P T2 is a second power boost value, PL2 is a second path loss value, and Δ is a power offset value between a format of the second random access signal and a reference PRACH format (for example, PRACH format 0).

[0134] For example, the second transmission power P2 is determined based on the above-mentioned 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 transmission power, and the value of the first parameter can comprise one or more of the following seven determination manners:

[0135] 1. the first parameter is the first target received power P R1 , and the second parameter is the second target received power P R2 , in this case, PR2 = P R1 (4);

[0136] 2. The first parameter is a first power boost value P T1 , and the second parameter is a first power boost value P T2 , and in this case, the following is satisfied: P T2 = P T1 (5);

[0137] 3. The first parameter is a first path loss value PL1, and the second parameter is a second path loss value PL2, and in this case, the following is satisfied: PL2 = PL1 (6).

[0138] 4. The first parameter is a sum of P R1 and PL1, and the second parameter is a sum of P R2 and PL2, and in this case, the following is satisfied: P R2 + PL2 = P R1 + PL1 (7).

[0139] 5. The first parameter includes P R1 and P T1 , and the second parameter includes P R2 and P T2 , and in this case, the following is satisfied: P R2 + P T2 = P R1 + P T1 (8);

[0140] 6. The first parameter includes P T1 and PL1, and the second parameter includes P T2 and PL2, and in this case, the following is satisfied: P T2 + PL2 = P T1 + PL1 (9).

[0141] 7. The first parameter includes P R1 , P T1 , and PL1, and the second parameter includes P R2 , P T2 , and PL2, and in this case, the following is satisfied: P R2 + P T2 + PL2 = P R1 + P T1 + PL1 (10).

[0142] Further, the first power boost value P T1 includes at least one of the following:

[0143] 2.1) a first power ramping step P step1 ;

[0144] That is, the second power ramping value P T2 may include a second power ramping step P step2 , at this time, P step2 = P step1 (11);

[0145] 2.2) a first count value P count1 ;

[0146] That is, the second power ramping value P T2 may include a second count value P count2 , at this time, P count2 = P count1 (12);

[0147] 2.3) a first product K1; the first product is the product of a first difference value and a first power ramping step P step1 , the first difference value is the difference between the first count value P count1 and a set constant D, that is, the first product K1 satisfies: K1 = (P count1 -D) * P step1 (13);

[0148] That is, the second power ramping value P T2 may include a second product K2, at this time, K2 = K1 (14).

[0149] In a possible implementation, the first random access signal and the second random access signal correspond to the same synchronization signal and physical broadcast channel block SSB index. That is, the spatial domain information of the first random access signal and the second random access signal is the same.

[0150] The above branch has the beneficial effect of: the spatial domain configuration when sending the second random access signal is clear. Further improve transmission efficiency and reduce transmission power consumption;

[0151] Specifically, the method further includes:

[0152] S111, sending the first random access signal in a first time unit;

[0153] S112, sending the second random access signal in a second time unit;

[0154] Wherein, the interval between the first time unit and the second time unit is less than the first time interval.

[0155] For example, the first time interval is a predefined value, or the network device sends time information including the first time interval. It can be understood that the time information can belong to the configuration information, or the time information is independent of the configuration information.

[0156] In a possible implementation manner, the terminal device starts a first timer at the first time unit or the next time unit after the first time unit, i.e., the time unit of sending the first random access signal or the next time unit after the time unit of sending the first random access signal, and the duration of the first timer is the first time interval.

[0157] In a possible implementation manner, the interval between the first time unit and the second time unit is less than the first time interval, which can also be expressed as that the first timer is running or not expired at the second time unit or when the second random access signal is sent.

[0158] The beneficial effect of the branch is that the association between the transmission power of the first random access signal and the second random access signal in the disclosure is applicable only within the predefined / network configured time period. The time validity of the terminal device following the previous transmission power scheme is further improved.

[0159] It can be understood that the unit of the time unit can be a time slot, an orthogonal frequency division multiplexing (OFDM) symbol, a radio frame, a half frame, a millisecond (ms), a second (s), or other time granularities, which are not specifically limited in the disclosure.

[0160] Specifically, the first SIB1 is non-broadcast system information, or the first SIB1 is on-demand triggered system information.

[0161] For example, when the first SIB1 is non-broadcast system information, or when the first SIB1 is on-demand triggered system information, the network device sends the first SIB1 to the corresponding terminal device.

[0162] 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.

[0163] It should be noted that the processes of the four-step random access, the two-step random access, the contention-based random access, and the non-contention-based random access can refer to related technologies, and the disclosure does not make specific limitations.

[0164] Specifically, the method further comprises:

[0165] S101, receiving configuration information; wherein the configuration information comprises N second parameters corresponding to N first cells, the first random access signal is associated with the N first cells, and N is a positive integer greater than 1;

[0166] S102, determining the first parameter according to the N second parameters.

[0167] For example, the configuration information can be sent by a network device, the first cell is a power saving (NES) cell, 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, physical cell identifier) of the N first cells. The number of first cells corresponds to the second parameter one by one, for example, when N=3, including NES1, NES2 and NES3, three first cells, each first cell corresponds to a second parameter, that is, there are also three second parameters at this time, and the first parameter is determined based on the three second parameters.

[0168] Specifically, in step S101, the configuration information is received, including: receiving the configuration information in a second cell; wherein the SIB1 of the second cell is broadcast system information, and the second cell is a non-power saving cell.

[0169] Further, the disclosure provides three determination methods of the first parameter as follows:

[0170] 1) In the first embodiment, the first parameter is the maximum value of the N second parameters.

[0171] 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 first parameter including the first power boost value as an example (the case of the first parameter including the first target received power is the same), at this time, it can be known that the second power boost value corresponding to the three first cells NES1, NES2 and NES3 is obtained, if the second power boost value corresponding to NES1 is the maximum, 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.

[0172] Further, the first parameter can also be the minimum value of the N second parameters. If the second power boost value corresponding to NES2 is the minimum, then the first power boost value is the second power boost value corresponding to NES2, i.e., the first parameter is the second power boost value corresponding to NES2.

[0173] 2) In the second implementation, the first parameter includes a first path loss value, and the second parameter includes an SSB transmission power; N candidate path loss values corresponding to the N first cells are determined according to N SSB transmission powers, and the maximum candidate path loss value is determined as the first path loss value from the N candidate path loss values.

[0174] For example, the path loss is determined by the terminal device according to the power of the received SSB and the SSB transmission power. The terminal device first acquires candidate path loss values corresponding to NES1, NES2 and NES3 of the three first cells. If the candidate path loss value of NES2 is the maximum at this time, the first path loss value is the candidate path loss value of NES2, i.e., the first parameter is the candidate path loss value of NES2.

[0175] Further, the minimum candidate path loss value can also be determined as the first path loss value from the N candidate path loss values. If the candidate path loss value of NES1 is the minimum, the first path loss value is the candidate path loss value of NES1, i.e., the first parameter is the candidate path loss value of NES1.

[0176] 3) In the third implementation, 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 of the N second parameters; or the first power boost value is the power boost value of the first cell corresponding to the maximum value of the N third parameters, and the third parameter is determined according to the second parameter.

[0177] For example, the second parameter includes a second target received power. First, the second target received powers corresponding to NES1, NES2 and NES3 of the three first cells are acquired. If the second target received power of NES3 is the maximum at this time, the power boost value of NES3 is acquired, and the first power boost value is the power boost value of NES3 at this time, i.e., the first parameter is the power boost value of NES3.

[0178] Further, the first power boost value can also be the power boost value of the first cell corresponding to the minimum value of 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 acquired, and the first power boost value is the power boost value of NES1 at this time, i.e., the first parameter is the power boost value of NES1.

[0179] Exemplarily, the third parameter comprises at least one of: a sum of the second target received power and the second path loss value; and the second path loss value. At this time, according to the third parameter, the second parameter corresponding to all the first cells can be determined, and then the first parameter is obtained by referring to the above manner. Further, at this time, the second parameter comprises N SSB transmission powers corresponding to the N first cells: the second path loss values corresponding to the N first cells are determined according to the N SSB transmission powers. Still further, the first power boosting value can also be the power boosting value of the first cell corresponding to the minimum value of the N third parameters.

[0180] In the embodiments of the present disclosure, the first parameter can be determined based on the second parameter, and the determination manner of “maximum value” can improve the transmission efficiency and performance of the uplink wake-up signal. The determination manner of “minimum value” can reduce the power consumption of the terminal side for sending the uplink wake-up signal, and reduce the interference on the uplink transmission of other terminals.

[0181] It is worth noting that there is also a case of N = 1 in the embodiments of the present disclosure, at this time, the above configuration information only comprises one second parameter corresponding to the first cell, since there is only one first cell, at this time, the first parameter can be directly equal to the second parameter without using the determination manner of “maximum value” or “minimum value”.

[0182] Specifically, the configuration information further comprises N second time windows corresponding to the N first cells respectively, and the method further comprises:

[0183] S201, determining the first time window according to the N second time windows;

[0184] S202, receiving a first random access response (RAR) in the first time window, the first RAR being associated with the first random access signal.

[0185] Exemplarily, referring to FIG. 5, FIG. 5 is a schematic diagram of sending a first random access response according to an embodiment of the present disclosure. The terminal device sends a first random access signal to the network device, and the network device returns a first random access response (RAR) after receiving the first random access signal, to inform the terminal device that the first random access signal has been received. In this process, the terminal device needs to receive the first random access response in the first time window, and the first time window is determined based on the N second time windows in the configuration information.

[0186] Specifically, in step S201, the first time window is determined according to the N second time windows, comprising at least one of:

[0187] 1) the first time window is the maximum value of the N second time windows;

[0188] 2) the length of the first time window is a second time window corresponding to a first cell with a maximum value in the N fourth parameters; wherein the fourth parameters include at least one of the following: a second target received power; a second power boost value.

[0189] For example, the second time window is a receiving time window in the first cell. Taking the second target received power as an example, assuming that there are still three first cells NES1, NES2 and NES3, first, the second target received power corresponding to NES1, NES2 and NES3 is obtained, if the second target received power of NES3 is the maximum 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 a second time window corresponding to a first cell with a minimum value in the N fourth parameters.

[0190] In the embodiments of the present disclosure, the first time window can be determined based on the second time window. The determination method of "maximum value" can improve the transmission efficiency and performance of RAR. The determination method of "minimum value" can reduce the power consumption of the terminal side in detecting RAR.

[0191] Compared with the related art, the information configuration method disclosed in the present disclosure, the terminal device determines the power configuration of the uplink wake-up signal, thereby improving the signal transmission efficiency and reducing the device energy consumption, and the terminal device can reuse all or part of the power configuration mode of the previous uplink wake-up signal when performing random access, thereby further improving the coverage performance of the signal, reducing the redundant power boost step, and further improving the reliability and communication efficiency of the communication link. In addition, the terminal device determines the parameter configuration of the uplink wake-up signal through the configuration information sent by the network device, thereby improving the signal transmission efficiency and reducing the device energy consumption.
