For example, the base station related to the embodiment of the present application may be a base station in 5G or a base station in LTE, where the base station in 5G may also be referred to as a Transmission Reception Point (TRP) or a gNB. In this embodiment of the present application, the apparatus for implementing the function of the network device may be a network device, or may be an apparatus capable of supporting the network device to implement the function, for example, a chip system. In the embodiment of the present application, a device for implementing a function of a network device is a network device, and a network device is a base station, for example, to describe the technical solution provided in the embodiment of the present application.
In a wireless communication system, a base station may manage at least one cell, an integer number of UEs may be included in one cell, and the base station and the UEs may communicate in the cell. In this embodiment, the communication between the base station and the UE may include at least one of: the base station and the UE carry out uplink communication, namely the UE sends data to the base station through an uplink channel, and the base station receives the data sent by the UE; the base station and the UE perform downlink communication, that is, the base station transmits data to the UE through a downlink channel, and the UE receives the data transmitted by the base station. In the embodiments of the present application, at least one may also be described as one or more and may also be described as a positive integer. Wherein, the plurality may be two, three, four or more, and the application is not limited. In the embodiments of the present application, the integer number may be zero or a positive integer number.
When the base station and the UE perform uplink communication in the cell, the power control may be performed on the uplink channel, for example, the powers of the uplink channels received by different UEs by the base station may be approximately the same, so that the interference between uplink data of different UEs may be reduced. The uplink channel may include a Physical Random Access Channel (PRACH). In a wireless communication system, if the UE needs to communicate with the base station, the UE may access the base station first, and the PRACH is used to carry an access preamble (preamble) sent by the UE to the base station in the access process, so that the base station may detect the accessed UE.
Exemplarily, fig. 1 is a flowchart illustrating a process of a UE accessing a base station, and in this embodiment, a process of the UE accessing the base station may also be referred to as an access process for short. As shown in fig. 1, in step 101, a UE transmits an access preamble to a base station through a PRACH. The UE may determine an access preamble from at least one available access preamble, and transmit the determined access preamble to the base station through the PRACH. In step 102, the base station sends message 2(message 2, Msg2) to the UE. And after receiving the access preamble, the base station sends a message 2 to the UE, wherein the message 2 comprises the access preamble identification of the access preamble received by the base station. And the UE receives the message 2, and if the access preamble corresponding to the access preamble identification in the message 2 is the same as the access preamble sent by the UE to the base station, the UE considers that the access preamble sent by the UE can be received by the base station. Illustratively, if the access type is non-contention access, if the access preamble identifier in the message 2 is the same as the access preamble sent by the UE to the base station, the UE considers that the access preamble sent by the UE has been received by the base station. If the access type is contention access, if the access preamble corresponding to the access preamble identifier in the message 2 is the same as the access preamble sent by the UE to the base station, the UE considers that the access preamble sent by the UE may or may not have been received by the base station. If the access type is contention access, in step 101, multiple UEs may send the same access preamble to the base station through the PRACH, that is, access collisions of multiple UEs occur; in step 102, the UE may receive the message 2, and for a UE, the UE cannot determine whether the access preamble received by the base station is the access preamble transmitted by itself or the access preamble transmitted by other UEs, that is, the UE cannot determine whether the access preamble transmitted by the UE is received by the base station. Therefore, if the access type is contention access, the base station and the UE may perform transmission of message 3(message 3, Msg3) and message 4(message4, Msg4) for contention resolution, i.e. the base station and the UE further determine which UE sent the access preamble received by the base station through message 3 and message 4.
In a wireless communication system, for example, in NR, SUL is introduced in order to improve uplink coverage or increase uplink transmission rate. In NR and LTE, a base station and a UE may communicate using frequency domain resources, for example, NR may support a band below 6GHz to a band below 60GHz, and LTE may support a band below 3 GHz. In a possible scenario, LTE is deployed in a frequency band with lower frequency, and NR is deployed in a frequency band with higher frequency, for example, a central frequency point of an LTE carrier is 1.8GHz (1.8GHz carrier), and a central frequency point of an NR carrier is 3.5GHz (3.5GHz carrier), and due to reasons such as that the higher the carrier frequency is, the higher the path loss is, and the uplink transmission power of UE is limited, the uplink coverage of NR may be limited. At this time, if the uplink load of the LTE is light, or if the utilization rate of the uplink carrier of the LTE is low, the NR uplink transmission and the LTE uplink transmission may share the 1.8GHz carrier, so as to improve the NR uplink coverage, that is, the LTE uplink transmission may be performed on the 1.8GHz carrier by the LTE system, and the NR uplink transmission may be performed on the 1.8GHz carrier by the NR system. In this embodiment of the present application, in an NR system, a carrier shared by NR uplink transmission and LTE uplink transmission may be referred to as an NR SUL resource, an NR SUL carrier, an SUL resource, or an SUL carrier, for example, the above-mentioned 1.8GHz carrier; the carrier that is not shared by NR uplink transmission and LTE uplink transmission may be referred to as an NR carrier, e.g., the 3.5GHz carrier described above. The SUL carrier and the NR carrier may correspond to one NR cell. In the embodiment of the present application, an integer number of SUL carriers may be included in one NR cell.
Note that, in the NR cell, the frequency of the NR carrier may also be equal to or less than the frequency of the SUL carrier. For example, when the NR uplink load is high, the NR uplink transmission rate may be increased by introducing the SUL carrier to increase the uplink resource. In the embodiment of the present application, the sharing of the LTE carrier by the NR is taken as an example to describe the SUL carrier, which does not form a limitation on an application scenario of the embodiment of the present application, and the SUL carrier of the embodiment of the present application may be extended to the sharing of the carrier of the second communication system by other first communication systems.
For an NR cell, if the cell includes a SUL carrier, a UE supporting SUL in the cell may transmit PRACH to a base station through the NR carrier of the cell or through the SUL carrier of the cell. The UE supporting the SUL in the cell may determine a carrier used for transmitting the PRACH according to the downlink measurement quantity and the SUL selection threshold. The downlink measurement quantity may be a downlink Reference Signal Received Power (RSRP), for example: an RSRP (SSB-RSRP) of a Synchronization Signal Block (SSB), an RSRP (CSI-RSRP) of a channel state information reference signal (CSI-RS), an RSRP of a cell specific reference signal (CRS), or an RSRP of a downlink demodulation reference signal (DMRS). For the UE supporting the SUL, if the downlink RSRP estimated by the UE is smaller than the SUL selection threshold SUL-RSRP, the UE can send PRACH to the base station through the SUL carrier of the cell; and if the downlink RSRP estimated by the UE is greater than or equal to the SUL selection threshold SUL-RSRP, the UE can send the PRACH to the base station through the NR carrier of the cell.
For an NR cell, if the cell includes a SUL carrier, the UE supporting SUL in the cell transmits PRACH to the base station through the NR carrier of the cell or through the SUL carrier of the cell, and when performing power control on the PRACH, it may be according to PoThe transmit power of the PRACH is determined. Wherein, in the embodiment of the application, PoThe data type of the PRACH, which is an initial target received power, may be real, in dBm (milliwatts). PoMay be a parameter configured by the base station for the UE through signaling. In the embodiment of the present application, the signaling transmitted between the base station and the UE may be higher layer signaling or physical layer signaling. The higher layer signaling may be Radio Resource Control (RRC) signaling, broadcast messages, system messages, or Medium Access Control (MAC) Control Elements (CEs). The physical layer signaling may be signaling carried by a physical control channel or signaling carried by a physical data channel, wherein the physical control channel may be physical downlink controlA Physical Downlink Control Channel (PDCCH), an Enhanced Physical Downlink Control Channel (EPDCCH), a Narrowband Physical Downlink Control Channel (NPDCCH), or a machine type communication physical downlink control channel (MTC) MPDCCH. The signaling carried by the PDCCH or EPDCCH may also be referred to as Downlink Control Information (DCI). The physical control channel may also be a physical sidelink control channel (physical sidelink control channel), and signaling carried by the physical sidelink control channel may also be referred to as Sidelink Control Information (SCI).
In the cell supporting the SUL carrier, the power control method can be based on various power control methods according to PoThe transmit power of the PRACH is determined. In the embodiment of the present application, a specific power control method is described as an example, and the method does not limit the technical solution provided in the embodiment of the present application.
When the SUL is supported in the NR, an LTE-NR co-site deployment scenario and an LTE-NR non-co-site deployment scenario may be included. For simplicity of description, the embodiment of the present application is illustrated with one of the deployment scenarios as an example. Exemplarily, as shown in fig. 2, an LTE-NR co-sited deployment scenario is shown, i.e., the base station in fig. 2 supports LTE and NR. In fig. 2, SUL is supported in NR, a base station supports multiple antennas, the base station manages a cell c, there are UE1 and UE2 in the cell c, and the base station and the UE can communicate through beam 1 and beam 2 in the cell c. As shown in fig. 2, the UE1 and the UE2 support SUL, a beam 1 may correspond to an NR carrier (e.g., a carrier with a center frequency of 3.5GHz) and a SUL carrier (e.g., a carrier with a center frequency of 1.8 GHz), the UE1 may perform NR uplink communication or downlink communication with the base station on the NR carrier through the beam 1, and the UE1 and the UE2 may also perform NR uplink communication with the base station on the SUL carrier through the beam 1; beam 2 corresponds to an NR carrier (e.g., a carrier with a center frequency of 3.5GHz), and the UE2 may perform NR uplink communication or NR downlink communication with the base station on the NR carrier through beam 2. In the embodiment of the present application, one beam may correspond to one antenna port, and thus, beam 1 may also be described as antenna port 1, and beam 2 may also be described as antenna port 2.
As shown in fig. 2, for a UE in NR cell c, such as UE1 or UE2, it may send PRACH to the base station over the NR carrier of the cell or over the SUL carrier of the cell. When the UE sends the PRACH, the PRACH may be received according to an initial target received power P of the PRACHoThe transmit power of the PRACH is determined. In one possible implementation, the UE may rely on P of cell c as in equation (1)oDetermining an expected target received power P for a PRACHPRACH,target,f,cCan be based on P as in formula (2)PRACH,target,f,cDetermining a transmit power P of a PRACHPRACH,f,c(i)：

In the formula (1), deltaPreamble is an adjustment quantity, and the data type can be real number, and the unit is dB; illustratively, the deltaPreamble may be configured independently for various access preamble formats, wherein one access preamble format corresponds to one value of a set { subcarrier spacing for transmitting access preamble, time domain length of symbol for transmitting access preamble, sequence length of access preamble } or one value of a subset corresponding to the set. preambleTransmissionConter is the number of transmission times of the access preamble, for example, when the UE sends the access preamble to the base station in one access process, the nte of preambleTransmissionCo at the nth time of sending the access preamble takes the r value as n, n is a positive integer, for example, n is 1, 2, 3 or 4. powerRampingStep, which is a power ramping factor, may be used to increase the transmission power of the access preamble as the number of times the access preamble is transmitted increases, so that the probability of successful access may be increased, and the data type of powerRampingStep may be a real number in dB.
According to equation (2), if the uplink loss of the carrier transmitting the PRACH is approximately equal to PLf,c(i) The PRACH received by the base station has a power of approximately PPRACH,f,c(i)-PLf,c(i) Then the power of the PRACH received by the base station may be considered to be approximately the desired target received power PPRACH,target,f,cTherefore, the UE can be ensured to adopt reasonable PRACH transmitting power to ensure that the PRACH is correctly received. Based on the method, a PRACH power control method based on carrier frequency compensation is provided. I.e., in the formula (1), PoP may be configured independently for carrier level parameters, i.e., for NR carriers and SUL carriersoTo compensate for the PL to be estimated from the NR carrierf,c(i) For power control of PRACH for SUL carriers, a path loss difference is introduced due to a frequency difference between NR and SUL carriers. Specifically, when the UE transmits the PRACH through the NR carrier, the PRACH is determined according to equation (1) and equation (2), P in equation (1)oIs configured for NR carriersoA value of (d); when the UE transmits PRACH through the SUL carrier, the PRACH is determined according to equations (1) and (2), P in equation (1)oValue of (1) is P configured for SUL carrieroThe value of (c).
However, in the above PRACH power control method based on carrier frequency compensation, for the UE2, when PRACH is transmitted over the SUL carrier, it is used to estimate PLf,c(i) And the channel used for transmitting the PRACH includes beam 1 and beam 1 in addition to the path loss caused by the carrier frequency differenceThe path loss caused by the antenna gain difference between beams 2. Therefore, for the UE2, the PRACH power control method based on carrier frequency compensation can only compensate the path loss difference caused by the carrier frequency difference, and cannot compensate the path loss difference caused by the antenna gain difference, so that the receiving quality of the PRACH cannot be guaranteed, and the access success rate of the UE2 on the SUL carrier cannot be guaranteed, or the UE2 sends the PRACH on the SUL carrier with reasonable power, so that the power consumption of the UE2 is increased. Among other things, for UE2, for estimating PLf,c(i) May be described as an antenna gain P, the difference in antenna gain between beam 2 of (a) and beam 1 corresponding to the SUL carrier used for transmission of the PRACHAnt,1And antenna gain PAnt,2The difference between them. Wherein, PAnt,1Which can be shown in fig. 2 as the distance, P, in direction 2 from point a on beam 2 to point B on beam 2Ant,2Which can be shown in fig. 2 as the distance of point a on beam 1 to point C on beam 1 in direction 2. Where, the direction 1 is a direction in which the base station points to the UE1, and the direction 2 is a direction in which the base station points to the UE 2.
In order to solve the problem similar to that existing in the access process of the UE2, the flow shown in fig. 3 is a power control method provided by the embodiment of the present application, and is intended to improve the access success probability of the UE in the SUL scenario or reduce the power consumption of the UE.
As shown in the flow of fig. 3, for one SSB a in a plurality of synchronization signal blocks SSB, a base station sends an initial target received power configuration corresponding to the SSB a to a UE, where the initial target received power configuration corresponding to the SSB a is used to determine an initial target received power corresponding to the SSB a, and a downlink measurement amount corresponding to the SSB a and the initial target received power corresponding to the SSB a are used to determine a transmission power of a PRACH transmitted on an SUL carrier. Correspondingly, for one SSB a in the plurality of synchronization signal blocks SSB, the UE receives an initial target received power configuration corresponding to the SSB a, where the initial target received power configuration corresponding to the SSB a is used to determine an initial target received power corresponding to the SSB a, and the downlink measurement quantity corresponding to the SSB a and the initial target received power corresponding to the SSB a are used to determine a transmission power of a PRACH transmitted on an SUL carrier.
In the embodiment of the present application, for a technical feature, the technical features in the technical feature may be distinguished by "1", "2", "a", "B", and "C", and the like, and the technical features described in "1", "2", "a", "B", and "C" and the like are not in sequence or in size order.
The SSB referred to in the embodiments of the present application is sent by the base station to the UE, and the SSB may include one or more of the following information: primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Physical Broadcast Channel (PBCH). The PSS and the SSS may be used to determine a Physical Cell Identity (PCID), and may also be used for the UE to acquire downlink synchronization with the base station; the PBCH may be used to configure partial system information or to configure cell level parameters, e.g., the PBCH may be used to configure a system frame number and/or to configure an SSB index.
In a cell supporting multiple beams, a base station may transmit one or more SSBs to a UE. When the base station transmits a plurality of SSBs to the UE, one SSB may correspond to one SSB index and one SSB may correspond to one beam. Different SSBs may correspond to the same beam or different beams, which is not limited in this application. One beam may be one physical beam or one logical beam equivalent to a plurality of physical beams, and one beam may correspond to one antenna port. Wherein one physical beam may be a beam formed by at least one antenna. As described above, the index of the SSB may be indicated by the PBCH in the SSB. Illustratively, one example of a multi-beam cell is shown in fig. 4. As shown in fig. 4(a), the base station may manage 3 cells, one cell, two cells, and three cells, each having a coverage of about 120 °. As shown in fig. 4(B), for one cell in fig. 4, for example, cell one, in the cell, the base station may transmit 4 SSBs, one SSB of the 4 SSBs corresponds to one beam, and the cell is covered by 4 beams corresponding to the 4 SSBs.
With the method provided by the embodiment of the present application, as in the methods related to fig. 3, in a cell, a base station may send multiple SSBs to a UE, and the base station sends, to the UE, initial target received power configurations corresponding to the SSBs in the multiple SSBs, where the initial target received power configurations corresponding to the SSBs are used to determine initial target received power corresponding to the SSBs. For one SSB of the plurality of SSBs, the downlink measurement quantity corresponding to the SSB and the initial target received power corresponding to the SSB are used to determine the transmission power of the PRACH transmitted on the SUL carrier. In the cell, if the UE detects one SSB of the plurality of SSBs, when the UE sends the PRACH to the base station on the SUL carrier, the UE may determine the transmission power of the PRACH according to the downlink measurement amount corresponding to the SSB and the initial target reception power corresponding to the SSB.
With the method shown in fig. 3, for the UE2 in fig. 2, the initial target received power configuration is independently configured for each beam or each SSB, so that differences between beams can be considered, and a path loss difference caused by an antenna gain difference can be compensated, so that an access success rate of the UE2 on the SUL carrier can be ensured or the UE2 can be ensured to transmit PRACH on the SUL carrier with reasonable power.
Illustratively, with the method referred to in fig. 3, for beam 1 and beam 2 shown in fig. 2, beam 1 corresponds to SSB1, beam 2 corresponds to SSB2, and SSB1 corresponds to an initial target received power of

In summary, in the conventional PRACH power control method, the configured initial target received power is a carrier level parameter, and when the PRACH is used for transmitting on the SUL carrier in the multi-beam system, a path loss difference between a beam corresponding to the SUL carrier and a beam used for performing downlink measurement cannot be considered, so that an access success rate of the UE on the SUL carrier cannot be ensured, or the UE cannot be ensured to transmit the PRACH on the SUL carrier with reasonable power so as to increase power consumption of the UE. However, in the method provided in the embodiment of the present application, the configured initial target received power is an SSB-level parameter or a beam-level parameter, and when the initial target received power is used for performing power control on a PRACH transmitted on an SUL carrier, a path loss difference between a beam corresponding to the SUL carrier and a beam used for performing downlink measurement may be considered, so that an access success rate of a UE on the SUL carrier may be improved by ensuring a received quality of the PRACH, or the PRACH may be transmitted by using a reasonable power on the SUL carrier by the UE so as not to increase power consumption of the UE.
It should be noted that the method provided in the embodiment of the present application is not limited to the SUL scenario, and for example, the method may also be applied to other scenarios in which uplink and downlink beams are inconsistent.
Based on the method provided by the embodiment of the application, in a possible implementation, in a cell supporting multiple beams, an initial target receiving power of an NR carrier of a carrier level may be configured, which is used for a UE to determine a transmission power of a PRACH when the NR carrier transmits the PRACH; the initial target received power of a plurality of SSB-level SUL carriers, that is, the initial target received power in the method related to fig. 3, may be configured to be used by the UE to determine the transmission power of the PRACH when the SUL carrier sends the PRACH.
In the methods provided in the embodiment of the present application, for example, in the methods related to fig. 3, for the PRACH, the initial target received power configuration corresponding to the SSB may be an initial target received power corresponding to the SSB, or may also be an initial target received power offset corresponding to the SSB, where the initial target received power offset corresponding to the SSB is an offset of the initial target received power corresponding to the SSB with respect to the initial target received power at a carrier level. Illustratively, the carrier level initial target received power may be a cell initial target received power for NR carriers or a carrier level common initial target received power for SUL carriers. The cell initial target receiving power of the NR carrier is used to determine the transmitting power of the PRACH sent on the NR carrier, and the carrier level common initial target receiving power of the SUL carrier is used to determine the transmitting power of the PRACH sent on the SUL carrier. The carrier-level initial target received power may be preconfigured, or may be sent to the UE by the base station, which is not limited in this application. By the method, the signaling carrying the initial target receiving power configuration can be flexibly designed according to the requirement of the network on the signaling overhead. For example, when the network is not sensitive to signaling overhead, the initial target received power configuration corresponding to the SSB may be the initial target received power corresponding to the SSB, and the calculation amount when the base station side and the UE side determine the initial target received power may be reduced by directly configuring the initial target received power; when the network is sensitive to signaling overhead, the initial target received power configuration corresponding to the SSB may be an initial target received power offset corresponding to the SSB, so that the signaling overhead may be reduced.
Illustratively, when the initial target received power configuration configured by the base station for the UE is the initial target received power offset, for beam 1 and beam 2 shown in fig. 2, beam 1 corresponds to SSB1 and beam 2 corresponds to SSB2, the base station may transmit the initial target received power offset corresponding to SSB1 for the UE

The number of SSB indexes corresponding to different initial target received power configurations in the N1 initial target received power configurations may be the same or different, and the application is not limited. Wherein N1 is an integer greater than or equal to 2, and N2 is a positive integer.

Among the values OF the cells OF the signaling RACH-ConfigGeneric provided in the embodiments OF the present application, SEQUENCE represents a SEQUENCE, for example, SEQUENCE (SIZE (1.. N2)) OF ssbinder represents that N2 ssbinders are included in the SEQUENCE from 1 st to N2 th ssbinders; INTEGER represents an INTEGER, e.g., INTEGER (-200. -74) represents an INTEGER having a value between-200 and-74.
The second RACH general configuration information RACH-ConfigGeneric:
the RACH general configuration information includes at least two initial target received power configuration indexes, and an initial target received power may be determined according to one of the at least two initial target received power configuration indexes. For one initial target received power configuration index of the two initial target received power configuration indexes, the initial target received power configuration index corresponds to at least one SSB index, one SSB index of the at least one SSB index corresponds to one SSB, the at least one SSB index corresponds to at least one SSB, and the initial target received power determined according to the initial target received power configuration index is the initial target received power corresponding to the at least one SSB.
Illustratively, as shown below, N1 initial target received power configuration indexes, preamblereceivedtargetpowerner, are included in the RACH-ConfigGeneric, and one initial target received power preambleReceivedTargetPower can be determined according to each initial target received power configuration index. For any initial target received power configuration index in the N1 initial target received power configuration indexes, the initial target received power configuration index corresponds to N2 SSBindex, and the initial target received power preamberceivedtargetpower determined according to the initial target received power configuration index is the initial target received power of N2 SSBs corresponding to the N2 SSB indexes. The number of SSB indexes corresponding to different initial target received power configuration indexes in the N1 initial target received power configuration indexes may be the same or different, and the application is not limited. Wherein N1 is an integer greater than or equal to 2, and N2 is a positive integer.
Figure BDA0001618200220000111
The third RACH general configuration information RACH-ConfigGeneric:
for one SSB of the at least one SSB, the RACH general configuration information includes an initial target received power configuration corresponding to the SSB.
Exemplarily, as shown below, the RACH general configuration information includes SSBs and a corresponding List SSB-preamplablereceived target power-List of initial target received power configurations, which is used to configure initial target received power configurations corresponding to N3 SSBs. The list includes N3 SSBs and the corresponding configuration SSB-preambleReceivedTargetPower of the initial target received power configuration. For any one of the N3 corresponding configurations, it is used to indicate an SSB index ssbinder and an initial target received power configuration preamberceivedtargetpower corresponding to the SSB index. Wherein N3 is a positive integer.

It should be noted that, in the specific example of the RACH-ConfigGeneric listed in the three RACH general configuration information RACH-ConfigGeneric, the description is made taking the example that the initial target received power configuration is the initial target received power, and this information may also be replaced with the initial target received power offset.
In the methods provided in the embodiment of the present application, for example, in the methods related to fig. 3, when a plurality of SUL carriers are supported in a cell, an initial target received power configuration corresponding to an SSB may be independently configured for each SUL carrier of the plurality of SUL carriers, and the initial target received power configurations corresponding to the SSBs of each SUL carrier may be the same or different, which is not limited in the present application. For example, the method may be described as: for one SUL carrier a of the SUL carriers, for one SSB a of the plurality of synchronization signal blocks SSB, the base station sends an initial target received power configuration corresponding to the SSB a to the UE, where the initial target received power configuration corresponding to the SSB a is used to determine an initial target received power corresponding to the SSB a, and a downlink measurement quantity corresponding to the SSB a and the initial target received power corresponding to the SSB a are used to determine a transmission power of a PRACH transmitted on the SUL carrier a. Correspondingly, for one SUL carrier a of the plurality of SUL carriers, for one SSB a of the plurality of synchronization signal blocks SSB, the UE receives an initial target received power configuration corresponding to the SSB a, where the initial target received power configuration corresponding to the SSB a is used to determine an initial target received power corresponding to the SSB a, and a downlink measurement amount corresponding to the SSB a and the initial target received power corresponding to the SSB a are used to determine a transmission power of a PRACH transmitted on the SUL carrier a.
Illustratively, 2 SUL carriers (e.g., SUL carrier B and SUL carrier C) and 2 SSBs (e.g., SSB and SSB C) are supported in a cell.
For example, for SUL carrier B, the base station may send, to the UE, an initial target received power configuration corresponding to SSB and an initial target received power configuration corresponding to SSB C, where a downlink measurement quantity corresponding to SSB and the initial target received power corresponding to SSB are used to determine transmission power when PRACH is transmitted on SUL carrier B through SSB, and a downlink measurement quantity corresponding to SSB C and the initial target received power corresponding to SSB C are used to determine transmission power when PRACH is transmitted on SUL carrier B through SSB C.
Further exemplarily, for the SUL carrier C, the base station may send, to the UE, an initial target received power configuration corresponding to the SSB and an initial target received power configuration corresponding to the SSB C, where a downlink measurement quantity corresponding to the SSB and an initial target received power corresponding to the SSB are used to determine a transmission power when the PRACH is transmitted on the SUL carrier C through the SSB, and a downlink measurement quantity corresponding to the SSB C and an initial target received power corresponding to the SSB C are used to determine a transmission power when the PRACH is transmitted on the SUL carrier C through the SSB C.
In the method related to fig. 3, the base station may send an initial target received power configuration corresponding to the SSB to the UE through a system message carried by a physical data channel (e.g., a Physical Downlink Shared Channel (PDSCH)) or through a PBCH.
In the method provided in the embodiment of the present application, carrier-level power control is taken as an example for description, and it should be noted that the method provided in the embodiment of the present application can also be applied to bandwidth part (BWP) level power control.
When the base station and the UE perform wireless communication by using the frequency domain resources, the base station manages the carrier frequency domain resources, and allocates the frequency domain resources for the UE from the carrier frequency domain resources, so that the base station and the UE can perform communication by using the allocated frequency domain resources. The carrier frequency domain resource may be a system frequency domain resource, or may be a frequency domain resource that can be managed and allocated by the base station. The carrier frequency domain resource may be a contiguous segment of frequency domain resources, which may also be referred to as a carrier.
BWP is a resource in a carrier. Illustratively, the base station configures BWP for the UE from the carrier, and the base station schedules the UE in the configured BWP. The base station may allocate some or all of the resources in the configured BWP to the UE for communication between the base station and the UE. The BWP configured by the base station for the UE is included in the carrier, and may be a continuous or discontinuous partial resource in the carrier, or may be all resources in the carrier. BWP may also be referred to as bandwidth resources, frequency domain resource portions, partial frequency domain resources, frequency resource portions, partial frequency resources, carrier BWP, or by other names, which is not limited in this application. When BWP is a segment of contiguous resources in a carrier, BWP may also be referred to as a sub-band, a narrowband, or by other names, which is not limited in this application.
When the method provided by the embodiment of the present application is applied to BWP-level power control, that is, when PRACH is transmitted in BWP, equation (2) and P in each equation corresponding to equation (2) in the embodiment of the present application are involvedPRACH,f,c(i) For the transmit power of PRACH in the BWP, PLf,c(i) Is replaced with the estimated downlink path loss for the BWP. The formulas corresponding to formula (2) may be formula (4), formula (6) or formula (8).
Fig. 5 is a diagram illustrating a procedure for accessing a base station by a UE according to an embodiment of the present application. In the access procedure, the cell in which the UE is located supports the SUL carrier, and the UE supports the SUL carrier is taken as an example for description.
S501, the base station sends SSB to the UE, and the UE detects the SSB.
In a wireless communication system based on Orthogonal Frequency Division Multiplexing (OFDM), such as NR and LTE, frequency domain resources for data transmission by a base station and a UE may be represented as subcarriers, and a distance between adjacent subcarriers may be described as a subcarrier spacing. In a wireless communication system, for example, NR, a plurality of subcarrier spacings are introduced to accommodate transmission scenario diversity, traffic diversity, and the like. For example, NR may support subcarrier spacing of 7.5kHz, 15kHz, 30kHz, 60kHz, 120kHz, and 240 kHz. At least one of the plurality of subcarrier spacings may also be used when the base station transmits the SSB to the UE.
In this embodiment, when the base station sends the SSBs to the UE, multiple SSBs may be sent within one time window with the time window as a period, where one SSB corresponds to one beam, and different SSBs may correspond to different beams or the same beam, which is not limited in this application. The length of the time window may be in units commonly used in the art, such as seconds, milliseconds, microseconds, frames, subframes, sub-subframes, slots, half-frames, minislots, symbols, transmission time intervals, or other units of time. In the embodiment of the present application, the description may be made by taking an example in which the length of the time window is 5 ms.
Illustratively, when SSBs are transmitted using 15kHz or 30kHz subcarrier spacing, at most 4 SSBs are transmitted in a 5ms window in a frequency band below 3GHz, the 4 SSBs corresponding to 4 beams, wherein 1 SSB may be mapped to 4 OFDM symbols; in the 3GHz to 6GHz band, up to 8 SSBs may be transmitted in a 5ms window, the 8 SSBs corresponding to the 8 beams. When SSBs are transmitted using 120kHz or 240kHz subcarrier spacing, up to 64 SSBs are transmitted in a 5ms window, corresponding to 64 beams.
The UE detects the SSB in the time window. If an SSB is detected or received, the UE may determine the index of the SSB based on the PBCH in the SSB.
S502, the base station sends initial target receiving power configuration corresponding to the SSB to the UE, the initial target receiving power configuration is used for determining initial target receiving power corresponding to the SSB, and the initial target receiving power corresponding to the SSB and downlink measurement corresponding to the SSB are used for determining transmitting power of PRACH transmitted in SUL carrier. Correspondingly, the UE receives an initial target received power configuration corresponding to the SSB, where the initial target received power configuration is used to determine an initial target received power corresponding to the SSB, and the initial target received power corresponding to the SSB and the downlink measurement corresponding to the SSB are used to determine the transmission power of the PRACH transmitted on the SUL carrier
The methods related to fig. 3 may be applied in S502.
In this embodiment of the present application, when the base station sends multiple SSBs to the UE, for the multiple SSBs, the base station may configure initial target received power configurations corresponding to the SSBs for the UE. In the multiple SSBs, the initial target received power configurations of different SSBs may be the same or different, and the application is not limited thereto.
S503, the UE sends PRACH to the base station, and the base station receives the PRACH sent by the UE.
For the SSB received by the UE in S501, the UE performs downlink measurement on the downlink signal corresponding to the SSB to obtain a downlink measurement amount of the downlink signal. The downlink signal may be, for example, the SSB or a downlink reference signal, and the downlink reference signal may be a downlink reference signal such as a cell specific reference signal (CRS), a demodulation reference signal (DMRS), or a channel state information reference signal (CSI-RS); the downlink measurement quantity may be RSRP.
If the RSRP measured by the UE is less than the SUL selection threshold, referring to each method related to fig. 3 or referring to S502, the UE may determine the transmission power of the PRACH according to the initial target reception power configuration corresponding to the SSB received by the UE, and send the PRACH to the base station on the SUL carrier with the determined transmission power of the PRACH. In this scenario, the UE may be considered as an edge user in the NR cell, and therefore, the transmission quality of the uplink signal between the UE and the base station may be improved by the SUL carrier.
In the foregoing embodiment of the present application, the method provided in the embodiment of the present application is introduced from the perspective of interaction between a base station and a UE. In order to implement the functions in the method provided by the embodiment of the present application, the base station and the UE may include a hardware structure and/or a software module, and implement the functions in the form of a hardware structure, a software module, or a hardware structure and a software module. Whether any of the above-described functions is implemented as a hardware structure, a software module, or a hardware structure plus a software module depends upon the particular application and design constraints imposed on the technical solution.
