Description

Technical Field

[0001] This disclosure generally relates to wireless communications, and more specifically, to transmission power control to mitigate transmission inferences. Background Technology

[0002] Wireless communication technology is a key component of an increasingly interconnected global communication network. Wireless communication relies on precisely allocated time and frequency resources to transmit and receive radio signals. Even though frequency reuse is a new technology to improve spectrum efficiency, simultaneous transmission on the downlink (DL) and uplink (UL) will cause serious interference, which may lead to design complexity of gNB (base station or BS) and user equipment (UE) and increase costs. Summary of the Invention

[0011] Figure 1 A flowchart illustrating a contention-based random access procedure is shown.

[0012] Figure 2 A flowchart illustrating a non-contention-based random access procedure is shown.

[0013] Figure 3 The subband non-overlapping fullduplex (SBFD) arrangement of the transmission resources is shown.

[0014] Figure 4 The structure of a wireless communication system is shown. Detailed Implementation

[0015] Figure 1 A flowchart of a contention-based random access process is shown, such as... Figure 1 As shown, the contention-based random access process mainly includes the following steps.

[0016] S101. The UE transmits a random access preamble on the physical uplink random access channel (PRACH), wherein the time-frequency domain position used to transmit the preamble is associated with the Random Access Radio Network Temporary Identifier (RA-RNTI).

[0017] S103. After receiving the random access preamble, the base station replies to the UE with a random access response on the physical downlink shared channel (PDSCH) scheduled by the physical downlink control channel (PDCCH). The random access response includes an authorization from the base station for subsequent uplink scheduling (i.e., the UE's Msg3).

[0018] S105. If the UE identifies a response associated with the preamble sent in S101 based on the RA-RNTI, the UE performs uplink scheduling according to the authorization obtained from the base station in S103 and sends Msg3 to the base station. Msg3 includes the UE identifier or contention resolution identifier; if the message is not received, the base station will reschedule Msg3 using a DCI format with a CRC scrambled by the Temporary Cell RNTI (TC-RNTI), and then the UE will retransmit Msg3 according to the DCI format.

[0019] S107. After receiving Msg3, the base station sends Msg4 to the UE based on the UE identifier. If the UE receives the message before the contention resolution timer expires and determines that Msg4 is the UE's expected Msg4 by unpacking, the UE determines that the random access procedure is successful. Otherwise, the random access procedure is determined to be unsuccessful, and random access is re-initiated.

[0020] Figure 2 A flowchart illustrating a non-contention-based random access procedure is shown, and as follows: Figure 2 As shown, the non-contention-based random access process mainly includes the following steps (steps S201 to S205).

[0021] S201. The base station first allocates a dedicated random access preamble to the UE via dedicated signaling (e.g., PDCCH command or RRC signaling). The time-frequency domain location for transmitting the random access preamble is specified.

[0022] S203. The UE sends a dedicated random access preamble at the specified time-frequency domain location.

[0023] S205. After receiving the random access preamble, the base station replies to the UE with a random access response on the Physical Downlink Shared Channel (PDSCH) scheduled by the Physical Downlink Control Channel (PDCCH). If the UE recognizes the response associated with the dedicated preamble sent in step S201, the UE determines that the random access procedure is successful; otherwise, it determines that the random access procedure is unsuccessful and re-initiates another random access procedure.

[0024] Based on current development trends, an evolved wireless communication system has been developed, supporting enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC). Full-duplex communication is the future direction of this evolved wireless communication system.

[0025] In TDD (Time Division Duplexing) wireless communication systems, time-domain resources can be allocated between downlink and uplink. Allocating a limited duration for the uplink in TDD leads to reduced coverage, increased latency, and decreased capacity. As a potential enhancement to this limitation of traditional TDD operation, it is worthwhile to investigate the feasibility of allowing simultaneous downlink and uplink transmission, or full-duplex, or more specifically, subband non-overlapping full duplex (SBFD), at the gNB side within a traditional TDD band. Therefore, a portion of frequency resources will be configured as semi-static downlink (DL) resources or uplink (UL) resources or UL subbands within flexible resources. Alternatively or additionally, a portion of frequency resources can be configured as semi-static UL resources or DL ​​resources or DL ​​subbands within flexible resources. Figure 3 An exemplary resource allocation for a time slot is shown, where the UL subband resides within the DL resource. Regardless of the approach, the uplink and downlink will exist in different frequency domain resources within the same time domain resource.

[0026] Therefore, cross-link interference may exist within the same time instance for time-frequency resources with different attributes. For example, because DL resources and UL resources are in the same time instance, DL transmission from a gNB (or base station (BS)) in the DL resource may interfere with uplink reception in the UL resource of the same gNB. Under SBFD, interference of DL transmission to UL reception is also called gNB self-interference. Under such transmission resource arrangements, it would be beneficial to make some improvements to overcome the potential interference.

[0027] In TDD wireless communication systems, time-domain resources can be divided into different attributes (e.g., downlink, uplink, and flexible resources (e.g., at least one of frames, time slots, or symbols)). These resource attributes can be configured or indicated by RRC (Radio Resource Control) signaling or physical layer signaling (including downlink control information (DCI)). For SBFD systems, such as... Figure 3 As shown, a portion of frequency domain resources can be configured as uplink resources or flexible resources within the downlink (e.g., downlink time slots or flexible time slots). Uplink resources within the downlink or flexible resources can be referred to as UL subbands, while the remaining downlink resources (excluding the UL subbands in the downlink BWP) can be defined as DL subbands. Alternatively or additionally, a portion of frequency domain resources can also be configured as downlink resources within the uplink or flexible resources. Downlink resources can be defined as DL subbands. The remaining uplink resources (excluding the DL subbands in the uplink BWP) can also be defined as UL subbands.

[0028] Different uplink transmissions (such as PRACH, PUSCH (physical uplink shared channel), and SRS) can be configured or instructed to be transmitted in the UL subband. For example, if the RACH (random access channel) procedure is permitted to be performed using UL subband resources, some PRACH resources, i.e., RO (RACH Occasion), can be defined within the UL subband. Furthermore, msg3 PUSCH can be scheduled for transmission in the UL subband via RAR (Random Access Request) UL grants. To ensure uplink transmission performance during the initial random access procedure, other mechanisms can be considered to compensate for the impact of base station (BS) self-interference on uplink transmission performance.

[0029] For example, increasing uplink transmission power is one way to ensure uplink transmission performance. For a single PRACH transmission, the transmission power can be determined using the following formula:

[0030] in, The maximum output power configured for the UE. PRACH target received power PREAMBLE_RECEIVED_TARGET_POWER .

[0031] PREAMBLE_RECEIVED_TARGET_POWER Set as preambleReceivedTargetPower + DELTA_PREAMBLE + (PREAMBLE_POWER_RAMPING_COUNTER–1)×PREAMBLE_POWER_RAMPING_ STEP + POWER_OFFSET_2STEP_RA .

[0032] preambleReceivedTargetPower (Preamble Receive Target Power) is the preamble receive target power configured via RRC signaling. As an example, for different preamble formats... DELTA_PREAMBLE The (preamble offset) values ​​are given in Table 1 below.

[0033] Table 1

[0034] PREAMBLE_POWER_RAMPING_COUNTER The (preamble power ramp counter) is a timer that records the number of PRACH transmissions. PREAMBLE_POWER_RAMPING_STEP (Preamble power ramp-up step) is a power increase configured via RRC signaling for each retransmission. For example, PREAMBLE_POWER_RAMPING_STEP The value is configured to 3dB, while the power of the first PRACH transmission is N dBm. Therefore, the power of the first retransmission or the second PRACH transmission will be (N+3) dB. POWER_OFFSET_2STEP_RA (two-step random access power offset) is used for 2-step RACH transmissions, while its value will be 0 during 4-step RACH processes.

[0035] For msg3 PUSCH, it can be based on cell-specific parameters. msg3-DeltaPreamble (msg 3-preamble offset) or " deltaPreamble The transmission power is determined by the preamble offset and the power of the PRACH transmission.

[0036] More specifically, .

[0037] Among them, by preambleReceivedTargetPower supply , and by msg3-DeltaPreamble or deltaPreamble supply Or, if msg3-DeltaPreamble and deltaPreamble If carrier f is not provided for serving cell c, then =0 dB. Furthermore, the actual value of the power offset between msg3 PUSCH and PRACH may be equal to ' msg3-DeltaPreamble ' 2. The value of the [dB] field.

[0038] In addition, the 3-bit "TPC command for PUSCH" field in the RAR UL license can also be used to further adjust the power of msg3 PUSCH scheduled by the RAR UL license. The relationship between the value of the "TPC command for PUSHC" field and the power adjustment value is shown in Table 2.

[0039] Table 2

[0040] The following examples illustrate some mechanisms for power control of uplink transmission during initial access, such as PRACH, msg3 PUSCH, etc.

[0041] Power enhancement for Msg1 Based on some examples, if the PRACH transmission resource (e.g., RACH timing (RO)) is located within the UL subband, a different transmission power can be determined compared to the case where the PRACH transmission source is located outside the UL subband. By increasing the transmission power, acceptable performance of the PRACH transmission can be expected.

[0042] Different methods can be used to determine the initial power of a PRACH transmission by considering the properties of PRACH transmission resources (such as RACH timing (RO)).

[0043] Power offset Based on some examples, if the RO is located within the UL subband, a power offset can be used to adjust the initial power of the PRACH transmission. For example, the transmission power of the PRACH can be determined using the following formula: [dBm] If RO is located within a UL sub-band, then define Power offset used to adjust the transmission power of PRACH. The value can be configured via RRC signaling, such as system information block 1 (SIB1) or master information block (MIB). Alternatively, The value can be predefined in the specification. However, if RO is located outside the UL sub-band, it can be determined. It is zero.

[0044] In some examples, if at least a portion of the resources of an RO overlaps with the UL subband, the RO is considered to be within the UL subband. On the other hand, if no portion of the resources of an RO overlaps with the UL subband, the RO is considered not to be within the UL subband. Alternatively, if the entire resources of an RO are within the UL subband, the RO is considered to be within the UL subband. On the other hand, if at least a portion of the resources of an RO are not within the UL subband, the RO is considered to be outside the UL subband. The same understanding applies to the entirety of this disclosure.

[0045] Alternatively or otherwise, (PARACH target received power) is set to preambleReceivedTargetPower+DELTA_PREAMBLE+(PREAMBLE_POWER_RAMPING_COUNTER–1) × PREAMBLE_POWER_RAMPING_STEP+POWER_OFFSET_2STEP_RA +Power_offset .

[0046] In this formula, a power offset is added to compensate for interference. Power_offset The value can be configured through higher-level signaling (such as RRC signaling or MAC layer signaling). Alternatively or otherwise, The value can be predefined in the specification. If RO is located within a UL sub-band, then it is defined. Power_offset This is used to adjust the transmission power of the PRACH. Alternatively, if the RO is located outside the UL subband, then determine... Power_offset It is zero.

[0047] preambleReceivedTargetPower Alternatively or additionally, multiple values ​​of the preamble receive target power are configured by the first RRC parameter, such as " preambleReceivedTargetPower One of these values ​​corresponds to PRACH transmission using the RO within the UL subband, while the other corresponds to PRACH transmission outside the UL subband. Because Based on preambleReceivedTargetPower Definitely. preambleReceivedTargetPower The two values ​​can provide Different values.

[0048] Alternatively, only the first RRC parameter can be configured with a single value, but a second parameter can be used to configure the power offset value. Therefore, if the RO is within the UL subband, the preamble receives the target power (“…”). preambleReceivedTargetPower The value is determined to be the sum of the value configured by the first RRC parameter and the power offset value configured by the second parameter. Otherwise, if the RO is not within the UL subband (or is outside the UL subband), the preamble receives the target power (“ preambleReceivedTargetPower The value specified is determined only by the first RRC parameter. Alternatively or additionally, the second parameter may be predefined in the specification.

[0049] DELTA_PREAMBLE Alternatively or alternatively, a new set of... DELTA_PREAMBLE Values ​​can be defined for PRACH transmissions using ROs within the UL subband. This set of values ​​can be independent of or different from the values ​​for PRACH transmissions using ROs outside the UL subband. In other words, there can be two sets of values, one for PRACH transmissions using ROs within the UL subband and the other for PRACH transmissions using ROs outside the UL subband. DELTA_ PREAMBLE value.

[0050] Table 3 below shows DELTA_PREAMBLE Examples are provided, where PRACH transmissions for different preamble formats are defined respectively. DELTA_PREAMBLE Combinations of values.

[0051] Table 3

[0052] Based on some examples shown in Table 4 below, multiple sets can be defined. DELTA_PREAMBLE value.

[0053] Table 4

[0054] According to some embodiments, a larger definition can be defined for PRACH transmissions using RO within the UL subband. DELTA_ PREMBLE Value. UEs that transmit PRACH using RO within the UL subband may suffer greater interference, therefore using a larger value... DELTA_PREAMBLE The value helps to increase PRACH transmission power more quickly for better coverage.

[0055] Alternatively or additionally, a set of PRACH transmission configurations can be used for ROs using UL subbands. DELTA_PREAMBLE Values ​​were derived to derive a set of values ​​for PRASH transmission using RO within the UL subband. DELTA_PREAMBLE Values. For example, an offset (e.g., an offset of X dB) can be configured via signaling or predefined. Therefore, X dB can be added to the configured PRACH transmission for ROs using UL subbands with the same preamble format. DELTA_ PREAMBLE The value is used to determine the PRACH transmission for RO within the UL subband. DELTA_PREAMBLE Value. For example, X could be 6dB. For preamble format 0, for PRACH transmission using RO within the UL subband. DELTA_PREAMBLE The value can be determined as X + 0 = 6dB. The same offset value can be used for different PRACH formats. In some examples, different offset values ​​can be used for different PRACH formats.

[0056] DCI Configuration According to some examples, the RACH procedure can be initiated by a PDCCH command. The power offset can be indicated via the information field in the DCI format of the PDCCH command. The information field can be included in the DCI format and is used to indicate the power offset value. For example, as shown in Table 5 below, N (e.g., 8) entries are defined in the specification or configured via RRC signaling. Therefore, entries with power offset values ​​can be defined in the DCI format of the PDCCH command. A bit information field or One bit. Symbol This represents a floor function used to get the next integer value from x. For example, =3. Alternatively, if the RO of the PRACH transmission is located within the UL subband, the power offset value indicated by the information field can be used to determine the power of the PRACH transmission. If the RO of the PRACH transmission is not located within the UL subband, the information field can be omitted.

[0057] Table 5

[0058] Alternatively, according to some examples, an information field can be defined in the DCI format of the PDCCH command. This information field is used to indicate whether an additional power offset should be used to determine the transmission power of the PRACH triggered by the PDCCH command. The additional power offset can be configured via higher-layer signaling (e.g., RRC signaling or MAC (Medium Access Control) layer signaling) or physical-layer signaling (e.g., the DCI format of the PDCCH command).

[0059] Alternatively or concurrently, according to some examples, the RACH procedure can be initiated by a PDCCH command. The power offset can be indicated via the information field in the DCI format of the PDCCH command. If the RO of the PRACH transmission is within the UL subband, the N MSBs (most significant bits) of the first information field can be used to indicate the power offset, where N is a positive integer. The first information field can be at least one of the random access preamble index, the SS / PBCH index, or the PRACH mask index.

[0060] In some of the examples above, two configurations can be provided for PRACH transmission, one for RO being located within the UL subband and the other for RO being located outside the UL subband. Alternatively or additionally, an offset can be introduced to add an offset on top of the regular PRACH transmission power. These measures can help overcome interference in transmissions using the UL subband.

[0061] Power Rise Alternatively, improvements in the control of power ramp-up (above the initial transmission power) for uplink transmission can offset inter-subband interference.

[0062] For PRACH transmissions, a power ramp counter can be used to count the number of RACH attempts. The power ramp step size can be configured. If the first RACH attempt fails, the UE can re-initiate the RACH process or retry the RACH by using a higher transmission power. The higher transmission power can be determined based on the power ramp step size; for example, the power of the PRACH transmission in a RACH retry can be equal to the transmission power used during the previous PRACH transmission plus the power ramp step size.

[0063] For PRACH transmissions within the UL subband, independent power ramp counters can be introduced. Therefore, two independent or different power ramp counters can be used separately for PRACH transmissions using ROs within the UL subband and ROs outside the UL subband. For example, C1 represents a power ramp counter used to record the number of PRACH attempts using PRACH transmission resources within the UL subband, and C2 represents another power ramp counter used to record the number of PRACH attempts using PRACH transmission resources outside the UL subband.

[0064] Alternatively or concurrently, independent or different power ramp-up steps can be defined for different PRACH attempts using PRACH transmission resources within the UL subband. Therefore, two independent or different power ramp-up step configurations can be defined or configured separately for PRACH transmissions using ROs within and outside the UL subband. For example, if the UE chooses to use an RO within the UL subband to transmit PRACH, the power ramp-up step between different attempts = P1. Or, if the UE chooses to use an RO outside the UL subband to transmit PRACH, the power ramp-up step between different attempts = P2. For example, P1 can be greater than or less than P2.

[0065] Alternatively, the UE can select a different type of RO (i.e., an RO within or outside the UL subband) to initiate a RACH attempt. For example, the UE can select an RO within the UL subband to initiate the first RACH attempt. If the UE fails, it can select another RO outside the UL subband to re-initiate the second RACH attempt (or a RACH retry). For the second RACH attempt, this is the first RACH attempt using an RO outside the UL subband; in response, the power ramp counter is set to 1.

[0066] Therefore, the power ramp value for each attempt can be determined based on the power ramp step size and the power ramp counter. More specifically, independent or different power ramp step sizes and power ramp counters can be used separately for PRACH transmissions using ROs within and outside the UL subband. For example, the power ramp can be determined using the following formula: (C1-1) × P1 + (C2-1) × P2 C1 and P1 represent the power ramp counter and power ramp step size for PRACH transmission using the RO within the UL subband. C2 and P2 represent the power ramp counter and power ramp step size for PRACH transmission using the RO outside the UL subband. An example is shown in Table 6, where the counters count multiple attempts separately, and the power ramp steps P1 and P2 are configured separately.

[0067] Table 6

[0068] Therefore, the power ramp value for each attempt can be determined separately based on the power ramp step size and power ramp counter for each case. Alternatively or additionally, different power ramp step sizes exist for PRACH transmissions using ROs within and outside the UL subband, respectively, but the power ramp counter can be shared for both cases. The power ramp value to be added to the power of the last PRACH transmission can be determined based on the type of RO resource selected for the current RACH attempt.

[0069] Table 7 shows an example where P1 represents the power ramp step size for PRACH transmissions using an RO within the UL subband, and P2 represents the power ramp step size for PRACH transmissions using an RO outside the UL subband. As shown, the counters here are shared by the two different types of RO selections, and the number of attempts is counted together, while the ramp step sizes are different.

[0070] Table 7

[0071] Alternatively or alternatively, according to some examples, the UE can be configured to select ROs of the same type (e.g., ROs within or outside the UL subband) for different RACH attempts. For example, if the UE selects an RO within the UL subband to initiate the first RACH attempt, the UE can also be configured to select an RO within the UL subband for subsequent RACH retries. Here, power ramping configurations for the selected type of RO can be applied. Similarly, if the UE selects an RO outside the UL subband to initiate the first RACH attempt, the UE can also be configured to select an RO outside the UL subband for subsequent RACH retries.

[0072] Alternatively or, according to some examples, if PRACH retransmission is configured, PRACH transmissions within a single RACH attempt can be selected to have the same type of RO (RO within or outside the UL subband). PRACH retransmission refers to multiple PRACH transmissions within a single RACH attempt.

[0073] SSB selection Based on some examples of RACH initiation procedures, the UE can configure a threshold via RRC parameters (e.g., rsrp-ThresholdSSB (Reference Signal Received Power - SSB Threshold)) to select an SSB (Synchronization Signal Block). For example, the UE can measure the SS-RSRP (Serving Cell Reference Signal Received Power) of the SSB. The UE can select an SSB whose SS-RSRP value is greater than or equal to the threshold configured for initiating the RACH procedure. If no SSB meets this condition (e.g., an SSB with an SS-RSRP greater than or equal to the threshold), the UE can alternatively select any SSB to initiate the RACH procedure. According to some examples, a relationship exists between SSBs and ROs based on predefined rules. Therefore, each RO can be associated with at least one SSB.

[0074] Alternatively, two thresholds can be configured for SSB selection or RO determination. One threshold corresponds to the selection of an RO within the UL subband, while the other corresponds to the selection of an RO outside the UL subband. Typically, the threshold corresponding to the selection of an RO within the UL subband is greater than the threshold corresponding to the selection of an RO outside the UL subband. Then, if the SS-RSRP value of the SSB is greater than both thresholds, and if the UE selects this SSB to initiate a RACH procedure, the UE can select either an RO within or outside the UL subband. If the SS-RSRP value of the SSB is only greater than the threshold corresponding to an RO outside the UL subband, and if the UE selects this SSB to initiate a RACH procedure, the UE can only select an RO outside the UL subband.

[0075] According to some examples, the two values ​​of these two thresholds can be configured by RRC signaling (e.g., rsrp-ThresholdSSB). Alternatively or additionally, the two values ​​of these two thresholds can be configured by two or more different RRC signalings. Alternatively or additionally, one of the two threshold values ​​can be configured by RRC signaling, while the other can be determined based on an offset, for example, by a calculation based on the configured threshold plus the offset. Exemplarily, the offset can also be configured via RRC signaling or defined in the specification.

[0076] The method described above can effectively define an SSB selection mechanism for PRACH transmissions using ROs within or outside the UL subband, thereby mitigating interference with UL transmissions.

[0077] PUSCH transmission power considerations Based on some examples, a PUSCH scheduled by RAR (Random Access Request) UL (Uplink) grant can also be called a msg3 PUSCH. The transmission power of the msg3 PUSCH can be determined based on the transmission power of the PRACH. For example, it can be determined through parameters. msg3-DeltaPreamble or deltaPreamble supply The value can be determined based on the PRACH transmission power and The value determines the transmission power of msg3 PUSCH.

[0078] Based on some examples, parameters can be provided by RRC signaling. msg3-DeltaPreamble or deltaPreamble Two or more values ​​are used to determine the transmission power of msg3 PUSCH.

[0079] Based on some examples, four different values ​​can exist. For instance, if both the corresponding PRACH and msg3 PUSCH are transmitted within the UL subband, the first value is used to determine the transmission power of msg3 PUSH. If the corresponding PRACH is transmitted within the UL subband, while msg3 PUSCH is transmitted outside the UL subband, the second value is used to determine the transmission power of msg3 PUSH. If the corresponding PRACH is transmitted outside the UL subband, while msg3 PUSCH is transmitted within the UL subband, the third value is used to determine the transmission power of msg3 PUSH. If both the corresponding PRACH and msg3 PUSCH are transmitted outside the UL subband, the fourth value is used to determine the transmission power of msg3 PUSH.

[0080] Alternatively or additionally, three different values ​​related to the transmission power setting may exist. For example, if the corresponding PRACH and msg3 PUSCH are both transmitted within the UL subband, or if the corresponding PRACC and msg3 PUSCH are both transmitted outside the UL subband, then a first value is used to determine the transmission power of msg3 PUSCH. If the corresponding PRACH is transmitted within the UL subband, while msg3 PUSCH is transmitted outside the UL subband, then a second value is used to determine the transmission power of msg3 PUSH. If the corresponding PRACH is transmitted outside the UL subband, while msg3 PUSCH is transmitted within the UL subband, then a third value is used to determine the transmission power of msg3 PUSH.

[0081] Alternatively or additionally, in some examples, scheduling of msg3PUSCH is only permitted within or outside the UL subband. On the other hand, PRACH can only be transmitted on ROs outside the UL subband. Alternatively or additionally, two different values ​​related to the transmission power setting may exist. For example, if msg3 PUSCH is transmitted within the UL subband, a first value is used to determine the transmission power of msg3 PUSH. If msg3 PUSCH is transmitted outside the UL subband, a second value is used to determine the transmission power of msg3 PUSCH.

[0082] Alternatively or additionally, in some examples, PRACH transmission is permitted only within or outside the UL subband. On the other hand, Msg3 PUSCH transmission is permitted only outside the UL subband. Alternatively or additionally, two different values ​​related to the transmission power setting may exist. For example, if the corresponding PRACH is transmitted within the UL subband, a first value is used to determine the transmission power of the msg3 PUSH. If the corresponding PRACH is transmitted outside the UL subband, a second value is used to determine the transmission power of the msg3 PUSCH.

[0083] Alternatively or additionally, in some examples, one or more values ​​of the additional power offset can be configured via RRC signaling. The value of (e.g., parameter) msg3-DeltaPreamble or deltaPreamble ), to determine the transmission power of msg3 PUSCH.

[0084] In some examples, alternatively or additionally, the value of the additional power offset can be configured by RRC signaling and The value. For example, if the corresponding PRACH and msg3 PUSCH are both transmitted within the UL subband, or if both PRACH and msg3 PUSCH are transmitted outside the UL subband, then according to The value determines the transmission power of msg3 PUSH. If PRACH is transmitted within the UL subband, while msg3 PUSCH is transmitted outside the UL subband, the power is determined based on the value of the additional power offset and... The value determines the transmission power of msg3 PUSCH. For example, it can be determined based on... The transmission power of msg3 PUSCH is determined by subtracting the additional power offset value from the PRACH value. Alternatively, if PRACH is transmitted outside the UL subband and msg3 PUSCH is transmitted within the UL subband, the transmission power can be determined based on... The transmission power of msg3 PUSCH is determined by the value of the additional power offset. For example, it can be determined based on the value of the additional power offset. The transmission power of msg3 PUSCH is determined by adding the value of the additional power offset to the value of the additional power offset.

[0085] Based on some examples shown in Table 8, two values ​​for the additional power offset (e.g., offset 1 and offset 2) can be configured by RRC signaling. The value. If both PRACH and msg3 PUSCH are transmitted within the UL subband, or if both PRACH and msg3 PUSCH are transmitted outside the UL subband, then it can be determined according to...

[0086] Table 8

[0087] Therefore, in some of the disclosed examples, the transmission power of msg3 PUSCH can be determined based on whether msg3 PUSCH is in the UL subband and / or whether the corresponding PRACH is in the UL subband.

[0089] Table 9

[0090] Alternatively or alternatively, according to some examples, PRACH is allowed to be transmitted within or outside the UL subband, while msg3 PUSCH can only be transmitted outside the UL subband. In this setup, the additional power offset value can be configured by RRC signaling. The value.

[0129] This document describes various exemplary embodiments of the present disclosure with reference to the accompanying drawings to enable those skilled in the art to make and use the disclosure. The disclosure is not limited to the exemplary embodiments and applications described and illustrated herein. Furthermore, the specific order and / or hierarchy of steps in the methods disclosed herein are merely exemplary. Based on design preferences, the specific order or hierarchy of steps in the disclosed methods or processes may be rearranged while remaining within the scope of this disclosure. Therefore, those skilled in the art will understand that the methods and techniques disclosed herein present various steps or actions in an exemplary order, and unless otherwise expressly stated, the disclosure is not limited to the specific order or hierarchy presented.

[0130] This disclosure is intended to cover any possible variations, uses, combinations or adaptive changes of this disclosure that follow the general principles thereof, and includes common knowledge and conventional technical means in the art that are not disclosed in this application.

[0131] It should be understood that this disclosure is not limited to the precise structures or operations shown above and in the accompanying drawings, and various modifications and changes can be made without departing from the scope of this application. The scope of this application shall be limited only to the appended claims.

[0132] The methods, devices, processes, circuits, and logic described above can be implemented in many different ways and in many different combinations of hardware and software. For example, all or part of the implementation may be a circuit containing an instruction processor or controller, such as a central processing unit (CPU), microcontroller, or microprocessor; it may also be an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a field-programmable gate array (FPGA); it may also be a circuit containing discrete logic or other circuit components, including analog circuit components, digital circuit components, or both; or any combination of the above. For example, the circuit may include discrete interconnect hardware components, or it may be combined on a single integrated circuit die, distributed among multiple integrated circuit dies, or implemented in a multiple chip module (MCM) of multiple integrated circuit dies in a common package.

[0133] Therefore, circuitry can store or access instructions for execution, or its functionality can be implemented solely in hardware. Instructions can be stored in a tangible storage medium other than transient signals (e.g., flash memory, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM)); or stored on a magnetic disk or optical disk (e.g., compact disc read-only memory (CDROM), hard disk drive (HDD), or other magnetic or optical disk); or on or on another machine-readable medium. Products such as computer program products may include storage media and instructions stored in or on the media, and when the instructions are executed by circuitry in the device, the device may cause the device to perform any of the processes described above or as shown in the accompanying drawings.

[0134] These implementations can be distributed. For example, the circuit may include multiple different system components (e.g., multiple processors and memories) and may span multiple distributed processing systems. Parameters, databases, and other data structures may be stored and managed separately, or may be merged into a single memory or database, and may be logically and physically organized in many different ways, and may be implemented in many different ways. Example implementations include linked lists, program variables, hash tables, arrays, records (e.g., database records), objects, and implicit storage mechanisms. Instructions may form parts of a single program (e.g., subroutines or other code segments), may form multiple separate programs, may be distributed across multiple memories and processors, and may be implemented in many different ways. Example implementations include standalone programs, as well as shared libraries as part of a library, such as a Dynamic Link Library (DLL). For example, the library may contain shared data and one or more shared programs that include instructions that, when executed by the circuit, perform any of the processes shown above or in the figures.

[0135] In some examples, each unit, subunit, and / or module of the system may include a logic component. Each logic component may be hardware or a combination of hardware and software. For example, each logic component may include an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), digital logic circuitry, analog circuitry, a combination of discrete circuitry, gates, or any other type of hardware or combination thereof. Alternatively or additionally, each logic component may include memory hardware (e.g., a portion of memory) containing instructions executable by a processor or other processor to implement one or more features of the logic component. When any logic component includes a portion of memory, and that portion of memory includes instructions executable by a processor, the logic component may or may not include a processor. In some examples, each logic component may simply be a portion of memory, or may be other physical memory containing instructions executable by a processor or other processor to implement the features of the corresponding logic component, and the logic component may not include any other hardware. Because each logic component includes at least some hardware, even if the included hardware includes software, each logic component may be interchangeably referred to as a hardware logic component.

[0136] The second action can be said to be "in response" to the first action, regardless of whether the first action directly or indirectly causes the second action. The second action can occur much later than the first action and still be in response to the first action. Similarly, even if an intervention occurs between the first and second actions, and even if one or more intervention actions directly lead to the execution of the second action, it can be said that the second action is a response to the first action. For example, if the first action sets a flag, and a third action later initiates the second action when the flag is set, then the second action can be said to be in response to the first action.
