Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to an uplink signal transmission method, apparatus, electronic device, and computer program product. Background Technology

[0002] PRACH (Physical Random Access Channel) is an uplink common signal whose main functions are to initiate access and to complete uplink timing synchronization between different terminal devices. In existing technologies, network devices need to detect PRACH signals on each PRACH transmission resource to respond to the possibility that a terminal might send a PRACH at any time to initiate an access procedure. This results in the frequent activation of various modules in the network device (e.g., baseband / IF / RF modules, or the main receiver), leading to high network power consumption.

[0047] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0048] Figure 1 This is a schematic diagram illustrating the determination of PRACH transmission resources provided by existing technology. For example... Figure 1 As shown, the PRACH configuration is based on System Information Block 1 (SIB1) indications, including fields such as prach-ConfigurationIndex (time domain start position and time domain resource usage indication), msg1-FrequencyStart (frequency domain start position indication), msg1-FDM (frequency domain resource usage indication), and ssb-perRACH-OccasionAndCB-PreamblesPerSSB (mapping relationship with the Synchronization Signal Block (SSB)). Among these:

[0049] 1) The prach-ConfigurationIndex indicates the time-domain resource configuration of PRACH, which can be obtained by querying a pre-defined table in the prior art;

[0050] 2) msg1-FrequencyStart and msg1-FDM indicate the frequency domain start position of the PRACH resource and the number of frequency domain resources occupied, respectively;

[0051] 3) ssb-perRACH-OccasionAndCB-PreamblesPerSSB indicates the mapping relationship between SSB and PRACH resources;

[0052] 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.

[0053] In addition, when the terminal device sends a PRACH signal, it also needs to determine the transmit power, which can be configured using the following formula:

[0054] P PRACH =min{P CMAX ,P PRACH,target +PL}dBm

[0055] Among them, P CMAXP represents 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 (i.e., SIB1), and the terminal device calculates the path loss value based on the measured receive-side power. PRACH,target The target power for PRACH is determined according to the following formula:

[0056] P PRACH,target

[0057] =preambleReceivedTargetPower+DELTA_PREAMBLE

[0058] +(PREAMBLE_POWER_RAMPING_COUNTER-1)

[0059] *PREAMBLE_POWER_RAMPING_STEP

[0060] Among them, preambleReceivedTargetPower is the PRACH receive power expected by the network side, and the specific value is configured by the network device to the terminal device through system information;

[0061] DELTA_PREAMBLE is an offset value set according to the PRACH format. Specifically, it can be determined based on the subcarrier spacing configured on the network side.

[0062] PREAMBLE_POWER_RAMPING_COUNTER is a power boost counter. It has a value of 1 for the initial transmission and increments by 1 for each retransmission.

[0063] The power ramp-up step size PREAMBLE_POWER_RAMPING_STEP is indicated by the field power Ramping Step (configured in system information).

[0064] As described above, in the prior art, network devices need to detect PRACH signals on each PRACH transmission resource to respond to the possibility that a terminal may send a PRACH at any time to initiate an access procedure. This results in the baseband or intermediate frequency module (e.g., the main receiver) in the network device needing to be frequently turned on, leading to high network power consumption. To address the above problems, this disclosure proposes an uplink signal transmission method, the specific method of which will be described in detail below. Figures 2-9 Provide a detailed description. Figure 2 Its application scenarios.

[0065] Figure 2This is a schematic diagram illustrating an application scenario of the uplink signal transmission method according to an embodiment of the present disclosure. For example... Figure 2 As shown, the application scenarios include at least: terminal device 10 and network device 20.

[0066] It should be understood that the signal detection method of this disclosure is applicable to both low-frequency and high-frequency scenarios. Application scenarios of the signal detection method of this disclosure include, but are not limited to, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future 5th-General (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems.

[0067] Network device 20 can be access network equipment (or access site). Access network equipment refers to equipment that provides network access functionality, such as radio access network (RAN) base stations. Specifically, network equipment may include base station (BS) equipment, or base station equipment and radio resource management equipment used to control the base station equipment. This network equipment may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations. Network equipment can be wearable devices or vehicle-mounted devices. Network equipment can also be a communication chip with a communication module.

[0068] For example, network equipment 20 includes, but is not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (eNB) in LTE systems, radio network controllers (RNC), node B (NB) in WCDMA systems, radio controllers and base station controllers (BSC) in CRAN systems, base transceiver stations (BTS) in GSM or CDMA systems, home base stations (e.g., home evolved node B, or home node B, HNB), baseband units (BBU), transmitting and receiving points (TRP), transmitting points (TP), or mobile switching centers, etc.

[0069] Furthermore, to further reduce the power consumption of network device 20, network device 20 can have two different receivers:

[0070] Main Receiver (MR): This receiver can be used to receive a second uplink signal, such as the signal specified in existing 3GPP NR technology. Specifically, it has strong receiving performance and can achieve a high transmission rate; however, it is also more complex and consumes more power.

[0071] Low-Power Wake-up Receiver (LR): This receiver can be used to receive the first uplink signal, such as the uplink low-power wake-up signal (UL LP-WUS) or the uplink wake-up signal (UL WUS). Its receiving performance is relatively weak, and its transmission rate is relatively limited, but at the same time, its receiver implementation is simple and low in complexity, therefore its power consumption is much lower than that of the main receiver.

[0072] Terminal device 10 may be user equipment (UE), terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication equipment, terminal agent, or user equipment, etc. This terminal device 10 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices 20 of one or more communication systems and receive network services provided by the network devices 20, including but not limited to the base station shown in the illustration.

[0073] The terminal device 10 may be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, user equipment in a future 5G network or user equipment in a future evolved PLMN network, etc.

[0074] like Figure 2 As shown, terminal device 10 can send two types of signals, and network device 20 can receive the corresponding transmission signals based on different receivers.

[0075] Figure 3 This is a flowchart illustrating an uplink signal transmission method according to an embodiment of the present disclosure. Figure 3 As shown, the uplink signal transmission method applied to the terminal device 10 may include at least the following steps.

[0076] In step S301, a first uplink signal is sent. This first uplink signal can trigger (the network device) to receive a second uplink signal, or it can enable (the network device) to receive the second uplink signal, or it can request (the network device) to receive the second uplink signal. Alternatively, the first uplink signal can trigger the master receiver to turn on, or it can enable the transmission of the second uplink signal, or the second uplink signal can only be transmitted after the first uplink signal is sent. As described above, network device 20 introduces LR on top of MR. By default, the MR of network device 20 is either off or in deep sleep most of the time. Simultaneously, the first uplink signal is detected based on LR. This first uplink signal can be a wake-up signal such as UL LP-WUS or ULWUS, which is not limited in this disclosure. Specifically, the function of the first uplink signal can be to trigger network device 20 or the cell corresponding to the first uplink signal to receive the second uplink signal, or to trigger network device 20 to turn on MR.

[0077] Thus, when terminal device 10 has a transmission requirement, it can send a first uplink signal to network device 20 to trigger network device 20 to enable MR and / or trigger network device 20 to receive a second uplink signal. The first uplink signal can be a PRACH signal, a signal for initiating initial access, a signal for initiating random access, etc., and this disclosure does not limit its scope. The specific spatial domain relationship between the first and second uplink signals, and the power control of the first and second uplink signals, will be discussed later. Figures 6-9 A detailed description will be provided in the following section.

[0078] The above process can be found in [reference]. Figure 4 To understand. Figure 4 This is an example diagram illustrating an uplink signal transmission method according to an embodiment of the present disclosure. Figure 4 As shown, Figure 4 This describes one possible scenario for MR, LR, the first uplink signal, and the second uplink signal in the time domain and receiver state, and does not constitute a limitation.

[0079] Figure 5 This is a further illustration of a flowchart of an uplink signal transmission method according to an embodiment of the present disclosure. For example... Figure 5 As shown, the uplink signal transmission method applied to network device 20 may include at least the following steps.

[0080] In step S501, a first uplink signal is received. This first uplink signal can trigger (the network device) to receive a second uplink signal, or it can enable (the network device) to receive the second uplink signal, or it can request (the network device) to receive the second uplink signal. Alternatively, the first uplink signal can trigger the master receiver to turn on, or it can enable the transmission of the second uplink signal, or the second uplink signal can only be transmitted after the first uplink signal has been transmitted. As described above, this step can be understood as the opposite step to step S301, and will not be elaborated further here.

[0081] As stated above, this disclosure aims to reduce energy consumption. Based on the introduction of LR (Range Reduction), this disclosure can further reduce energy consumption through the configuration of spatial information and the control of transmission power. The following will combine... Figures 6-7 , Figures 8-9 These two parts will be introduced separately:

[0082] I. Airspace Configuration

[0083] Figure 6 This is a schematic diagram illustrating the spatial configuration of an uplink signal transmission method according to an embodiment of the present disclosure. Figure 6 As shown, rectangles represent signal or transmission opportunities or resources (occasion), and multiple transmission opportunities or resources form a transmission opportunity set or resource set (occasion set or occasions); ellipses represent beam directions. It can be understood that if the ellipse directions are the same, it means that the beam information or spatial information is consistent, or that they are associated with the same SSB index.

[0084] Figure 6 (A) represents the correlation between the first uplink signal and the second uplink signal. Specifically:

[0085] Terminal device 10 sends a second uplink signal at a second transmission opportunity, wherein the second transmission opportunity belongs to a set of second transmission opportunities, and one or more second transmission opportunities in the set of second transmission opportunities are associated with a first uplink signal.

[0086] In one embodiment of this disclosure, when the second uplink signal is a PRACH signal, the second transmission timing may be a specific time window for the terminal device 10 to send the PRACH preamble.

[0087] Furthermore, the association of one or more second transmission opportunities in the second transmission opportunity set with the first uplink signal can be understood as the association of one or more second transmission opportunities in the second transmission opportunity set with the first parameter of the first uplink signal.

[0088] In one embodiment of this disclosure, the first parameter may include at least one or more of the following:

[0089] Beam information, spatial information, spatial transmission filter, corresponding synchronization signal index value, quasi-co-location configuration, quasi-co-location characteristics, etc.

[0090] Furthermore, the association of one or more second transmission opportunities in the second transmission opportunity set with the first parameter of the first uplink signal can be achieved in the following ways:

[0091] i) One or more of the second transmission opportunities have the same beam information as the first uplink signal. Here, "same beam" can be understood as the signal's propagation direction and coverage area in space being consistent.

[0092] ii) One or more of the second transmission opportunities have the same spatial information as the first uplink signal. The spatial information may include information such as the signal's angle of arrival, transmission angle, and spatial multiplexing. The same spatial information can be understood as the signal's propagation path and angle in space being similar.

[0093] iii) One or more of the second transmission opportunities have the same synchronization signal index value as the first uplink signal. The synchronization signal index value is used to distinguish different synchronization signal blocks, and each synchronization signal block corresponds to a specific index value (i.e., beam direction). The same synchronization signal index value can be understood as the corresponding synchronization signal blocks belonging to the same beam scanning period, thus aiding in time slot synchronization and symbol synchronization.

[0094] It should be noted that the aforementioned synchronization signal can be one or more of the following: SSB, Physical Broadcast Channel (PBCH), Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Low Power Synchronization Signal (LP-SS), or new synchronization signals in other generations of mobile communication technologies such as 6G. This disclosure does not limit it in this regard.

[0095] iv) One or more of the second transmission opportunities share the same quasi-co-location characteristics as the first uplink signal. The same quasi-co-location (QCL) characteristics can be understood as different signals exhibiting similarities or correlations in certain channel properties. These properties include the signal's angle of arrival (AoA), angle of departure (AoD), delay spread, Doppler spread, and receiver information / parameters.

[0096] v) One or more of the second transmission opportunities belong to the same quasi-co-location configuration as the first uplink signal. Here, belonging to the same quasi-co-location configuration can be understood as these signals being defined as having similar channel characteristics at the network planning and configuration level.

[0097] vi) One or more of the second transmission opportunities are identical to the spatial transmission filter of the first uplink signal. The spatial transmission filter is primarily used to filter signals in the spatial domain. It can enhance or suppress signals in certain directions based on the spatial characteristics of the signal (such as direction, angle, etc.). Having identical spatial transmission filters means that the spatial domain filtering operations performed on the signal are the same. This indicates that the signal is processed in the same way in the spatial domain, which results in similar propagation characteristics of the signal in space (such as coverage area, directionality, etc.).

[0098] It should be noted that one or more of the above association methods can be used. For ease of understanding, the following description will use iii) as an example to further illustrate the association method.

[0099] Figure 6 (B) and (C) represent the correlation between the synchronization signal and the first uplink signal. The transmission timing of the first uplink signal belongs to the first uplink signal set, which includes one or more transmission timings of the first uplink signal.

[0100] like Figure 6 As shown in (B), the first uplink signal set includes one or more transmission timings of the first uplink signal that correspond one-to-one with the synchronization signal index set. That is, synchronization signal index 0 corresponds to the first first uplink signal or the transmission timing of the first uplink signal, ..., synchronization signal index 3 corresponds to the fourth first uplink signal or the transmission timing of the first uplink signal.

[0101] Furthermore, the transmission timing of one or more first uplink signals in the first uplink signal set can also correspond one-to-one with the actual transmission synchronization signal index set. For example... Figure 6 As shown in (C), for example, if the synchronization signal with index value 2 does not actually occur, the first uplink signal timing can correspond one-to-one with the set of synchronization signal indices that actually occur. That is, synchronization signal index 0 corresponds to the first first uplink signal or the timing of the first uplink signal transmission, synchronization signal index 1 corresponds to the second first uplink signal or the timing of the first uplink signal transmission, synchronization signal index 3 corresponds to the third first uplink signal or the timing of the first uplink signal transmission, while synchronization signal index 2 does not correspond to the timing of the third first uplink signal or the timing of the first uplink signal transmission. It is also understood that the first uplink signal set may also include the timing of the fourth first uplink signal or the timing of the first uplink signal transmission, in which case the timing of this uplink signal or the timing of the uplink signal transmission is not associated with the synchronization signal / synchronization signal index.

[0102] Furthermore, the first uplink signal can also correspond to a set of transmission timings or resources, as detailed in [link to relevant documentation]. Figure 7Further description.

[0103] Figure 7 This is a schematic diagram further illustrating the spatial configuration of the uplink signal transmission method according to an embodiment of the present disclosure. For example... Figure 7 As shown, rectangles represent signal or transmission timing or resources, and ellipses represent beam directions. It can be understood that if the ellipse directions are the same, it means that the beam information or spatial information is consistent, or that they are associated with the same SSB index.

[0104] Continue with Figure 6 Taking case C as an example, Figure 7 The synchronization signal with index 2 did not actually transmit, so the transmission timing of the first uplink signal or the first uplink signal was only one-to-one with synchronization signal indices 0, 1, and 3 (i.e., ...). Figure 7 The three rectangles side by side in the first row on the right correspond to the first, second, and fourth transmission timings of the first uplink signal, respectively.

[0105] Now, with the second first uplink signal (i.e.) Figure 7 Taking the rectangle with a dark gray background in the middle of the first row on the right as an example, the first uplink signal can correspond to a set of transmission opportunities or resources (i.e., ... Figure 7 The four individual rectangles in the second row on the right have the same synchronization signal index (i.e., all are index 1) for this group of transmission opportunities or resources. In other words, the terminal device 10 can send the first uplink signal on all of this group of transmission opportunities or resources, or the terminal device 10 can send the first uplink signal only on a part of this group of transmission opportunities or resources. The specific number of transmissions can be pre-configured to the terminal device 10 by the network device 20 (e.g., based on system information).

[0106] Understandable Figure 7 The first uplink signal corresponds to a set of transmission timings or resources, applicable not only to situations where the signal corresponds to a set of transmission timings or resources. Figure 6 (C) in the text also applies to (C). Figure 6 (B) in the text is independent of whether the correspondence is based on actual transmission.

[0107] It needs to be explained that, Figure 6 and Figure 7 This applies not only to case iii), but also to other association methods (i.e. Figure 7 It could also be that multiple first uplink signals correspond to the same spatial information, multiple first uplink signals correspond to the same quasi-co-location characteristics, multiple first uplink signals correspond to the same spatial transmission filter, etc.

[0108] The above describes a specific method for reducing energy consumption through spatial configuration. This method clarifies the mapping relationship between the first uplink signal and the second uplink signal, enabling the spatial configuration when the terminal device 10 transmits the first and second uplink signals. Simultaneously, by setting multiple transmission opportunities or resources for the first uplink signal, the coverage performance of the signal can be further improved, thereby enhancing the reliability of the communication link. The following section will introduce how to reduce energy consumption through power control.

[0109] II. Power Control

[0110] Figure 8 This is a flowchart illustrating the power control method in an uplink signal transmission method according to an embodiment of the present disclosure. Figure 8 The power control method for the uplink signal transmission method applied to the terminal device 10 may include at least the following steps.

[0111] In step 801, the first transmit power of the first uplink signal is determined. The first transmit power is associated with a second parameter, which includes at least one of the following: a first target receive power, a first offset, a first power boost value, and a first path loss value.

[0112] The first target received power, the first bias, and the first power boost value can be obtained by the terminal device 10 from the configuration information received by the network device 20. In addition, the configuration information of the network device 20 may also include the first synchronization signal transmit power value. Furthermore, the first synchronization signal transmit power value can be used to determine the aforementioned first path loss value.

[0113] Further, the first power boost value includes at least one of the following: a first power boost step size, a first count value, and a first product, wherein the first product is the product of the first count value and the first power boost step size.

[0114] In one embodiment of this disclosure, the first transmit power can be determined by the following formula:

[0115] First transmit power = First target receive power (+ First bias) + First count value * First power boost value + First path loss value.

[0116] It should be noted that the first transmission power can be the maximum transmission power of the terminal device 10, or the maximum transmission power configured for the network device 20 (in the system information).

[0117] In step 802, the second transmit power of the second uplink signal is determined based on the first transmit power. The second transmit power is associated with a third parameter, which includes at least one of the following: second target receive power, second offset, second power boost value, and second path loss value.

[0118] Furthermore, the second power boost value includes at least one of the following: a second power boost step size, a second count value, and a second product, wherein the second product is the product of the second count value and the second power boost step size.

[0119] In one embodiment of this disclosure, the second transmit power can be determined by the following formula:

[0120] Second transmit power = Second target receive power (+ Second bias) + Second count value * Second power boost value + Second path loss value.

[0121] It should be noted that when determining the second transmit power based on the first transmit power, the second parameter of the first transmit power can be reused, including at least one of the following: the second path loss value is equal to the first path loss value, the second power boost value is equal to the first power boost value, the second count value is equal to the first count value, the second product is equal to the first product, the second transmit power is equal to the first transmit power, and the second bias is equal to the first bias.

[0122] For ease of understanding, Figure 9 A specific example of the above process is given.

[0123] Figure 9 This is a schematic diagram illustrating the power control method in an uplink signal transmission method according to an embodiment of the present disclosure. Figure 9 As shown, the horizontal axis represents the time domain, the rectangle represents the signal, and the area of ​​the ellipse represents the transmit power. The area enclosed by the dashed line represents the full power, and the area enclosed by the solid line represents the actual transmit power. In other words, the maximum actual transmit power is the full power.

[0124] This release clarifies the power control method for the first uplink signal and the second uplink signal, enabling the terminal device 10 to configure the transmit power when sending the first uplink signal and the second uplink signal.

[0125] Meanwhile, by setting the first uplink signal to be transmitted at full power, the coverage performance of the signal can be further improved, thereby enhancing the reliability of the communication link.

[0126] Meanwhile, by configuring the partial power control of the second uplink signal to reuse the configuration of the uplink wake-up signal, the coverage performance of the signal can be further improved, redundant power boosting steps can be reduced, and the reliability and efficiency of the communication link can be improved.

[0127] Furthermore, a first uplink signal is sent in the first time unit; a second uplink signal is sent in the second time unit; the interval between the first time unit and the second time unit is less than the first time interval.

[0128] The first time interval can be a predefined value, or the network device can send time information, which includes the first time interval. It is understood that the time information can be part of the aforementioned configuration information, or the time information and configuration information can be independent of each other.

[0129] In one embodiment of this disclosure, the terminal device 10 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 uplink signal is sent / the next time unit after the time unit in which the first uplink signal is sent, and the duration of the first timer is the first time interval.

[0130] In another embodiment of this disclosure, the interval between the first time unit and the second time unit is less than the first time interval. This can also be expressed as the first timer running or not timed out during the second time unit or when the second random access signal is sent.

[0131] This ensures that the correlation between the transmit powers of the first uplink signal and the second uplink signal in this disclosure applies only within a predefined / network configured time period. This further enhances the time-sensitivity of the terminal device 10's use of previous transmit power schemes.

[0132] It is understood that the unit of the aforementioned 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 disclosure does not impose any specific limitations.
