Technical Field
The present application relates to the field of communications, and in particular, to a control channel transmission method and a network device.
Background
User Equipment (UE) accesses a network and needs to perform cell search and acquire cell System Information (System Information). A New design is adopted for a Synchronous Signal in New Radio (NR), and a Synchronous Signal/Broadcast Channel Block (SS/PBCH Block) is introduced, wherein the SSB for short comprises an NR-Primary Synchronization Signal (PSS), an NR-Secondary Synchronization Signal (SSS) and an NR-Physical Broadcast Channel (PBCH). One SSB occupies 4 consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols, one SSB burst set is a time window with a duration of 5ms, and at most L SSBs can be transmitted within the 5ms SSB burst set. For different frequency bands, L has different values, for example, in a frequency band below 3GHz, L is 4; a frequency band of 3GHz-6GHz, L being 8; the frequency band of 6GHz-52.6GHz, L is 64.
After the cell search process, the UE has already acquired downlink synchronization with the cell, and the UE needs to further acquire system information and paging messages of the cell to perform random access in the cell. The system information, the paging message and the random access response are scheduled by a Physical Downlink Control Channel (PDCCH) corresponding to each of the system information, the paging message and the random access response. Therefore, the UE needs to know the transmission power adjustment between the control channel and the synchronization signal to ensure that the UE correctly receives the signal carried by the control channel.

Wherein the network device indicates the adjustment amount of the transmission power of the control channel through the information indicated by the common signal and/or the information of the common signal. For example, the network device may implicitly and/or explicitly indicate the adjustment amount of the transmission power of the control channel through the information indicated by the common signal, and may implicitly and/or explicitly indicate the adjustment amount of the transmission power of the control channel through the information indicated by the common signal and the information of the common signal.

As shown in fig. 8, S802, the UE receives a common signal; and S803, the UE determines the adjustment amount of the transmission power of the control channel according to the information indicated by the common signal and/or the information of the common signal. For example, the UE determines the adjustment amount directly and/or indirectly according to the information indicated by the common signal, or determines the adjustment amount directly and/or indirectly according to the information indicated by the common signal and the information of the common signal. It should be understood that direct determination or indirect determination herein includes direct determination of all or part of the adjustment amount or indirect determination of all or part of the adjustment amount. For example, a part of the adjustment amount is indirectly determined based on the information indicated by the common signal and the information of the common signal, and another part of the adjustment amount is directly determined based on the information indicated by the common signal.
The information indicated by the common signal includes other information than the information of the common signal itself, which may be determined directly or indirectly by the UE from the common signal, and may include, for example and without limitation, one or more of a control resource set of a control channel, a multiplexing pattern of the control channel, a subcarrier spacing of the control channel, a transmission resource of the control channel, adjustment information of transmission power of the control channel, and the like.

By the control channel transmission method or the communication equipment, the UE can determine or enable the network equipment to indicate the adjustment quantity of the transmission power of the control channel under the condition that the indicating bit number is not increased or is relatively less increased, so that the method and the communication equipment are suitable for the flexible and changeable communication scene of future communication and ensure that the UE correctly receives the signals borne by the control channel.
The present application is described below with reference to specific examples, which should be understood to be merely for helping those skilled in the art to better understand the present application, and not to limit the scope of the present application.
Example 1
This example mainly describes that the UE determines the adjustment amount according to the information indicated by the common signal (control resource set of control channel), and/or the network device indicates the adjustment amount through the information indicated by the common signal (control resource set of control channel).
The System broadcast Information is divided into a Master Information Block (MIB) and a System Information Block (SIB), wherein the MIB is basic configuration Information of the System and is transmitted on a fixed (physical) resource of PBCH, and the SIB is further divided into Remaining Minimum System Information (RMSI) and Other System Information (OSI). The UE determines a control resource set (core) of the control channel according to the information in the MIB. For example, the UE selects a certain time-frequency resource as a RMSI control resource set (RMSI CORESET) according to the first 4 bits of the RMSI-PDCCH-Config in the MIB and according to tables 13-1 to 13-8 in the 3GPP 38.213 protocol. When the time-frequency resource of the configured control resource set is larger, the corresponding supportable maximum aggregation level is also larger. Further, the same control information is transmitted with a larger aggregation level, the better the performance and coverage. Therefore, in order to meet a certain coverage requirement, when the time-frequency resources of the control resource set configured by the network device are small, the network device may achieve coverage similar to the control resource set with large time-frequency resources through some compensation on the transmission power.
When the (size of the) control resource set of the control channel is smaller than or equal to a preset threshold value, that is, the (size of the) time-frequency resource of the control resource set of the control channel is smaller than or equal to the preset threshold value, the adjustment amount includes any one or more of a first adjustment range, a first adjustment direction and a first adjustment value; when the (size of the) control resource set of the control channel is greater than or equal to the preset threshold value, that is, the (size of the) time-frequency resource of the control resource set of the control channel is greater than or equal to the preset threshold value, the adjustment amount includes any one or more of the following, a second adjustment range, a second adjustment direction, and a second adjustment value. Wherein (size of) the control resource set of the control channel may be the total number of (physical) resource blocks of the control resource set of the control channel. Alternatively, (size of) the control resource set of the control channel may be the total number of (physical) resource units of the control resource set of the control channel. Wherein the first adjustment value (e.g., 6bB) is greater than the second adjustment value (0 dB). Wherein a first adjustment range (e.g., [0, +12] dB) includes a first maximum adjustment value (e.g., 12dB) that is greater than or equal to a second maximum adjustment value (6dB) included in the second adjustment range (e.g., [ -6, +6]), wherein the first adjustment direction (e.g., upward adjustment) is opposite to the second adjustment direction (e.g., downward adjustment), or wherein the first adjustment direction (e.g., upward adjustment and/or no adjustment) is partially opposite to the second adjustment direction (e.g., downward adjustment and/or no adjustment). It should be understood that the above adjustment range, adjustment direction or adjustment value is only an example, and may be other ranges, values or directions, which is not limited in this application.
For example, taking the following tables 1 and 2 as examples, when the time-frequency resource configuration of the control resource set satisfies: when the total number of (physical) Resource Blocks (RBs) is less than or equal to 24, that is, when the product of the value in the third column and the value in the fourth column in tables 1 and 2 is less than or equal to 24, the maximum aggregation level supportable by the control channel is 4, and at this time, the power adjustment range of the control channel and the common signal may be [0, +12] dB, or the adjustment direction may be upward adjustment (that is, it may be understood that the transmission power adjustment direction of the control channel relative to the common signal is an adjustment amount greater than 0); when the total number of RBs configured by the control resource set is greater than or equal to 24, the power adjustment range of the control channel and the common signal is [ -6, +6] dB, or the adjustment direction may be downward adjustment (i.e., the adjustment direction of the transmission power of the control channel relative to the common signal is an adjustment amount smaller than 0); when the total number of RBs is equal to 24, the adjustment direction may be unadjusted, i.e., the transmission power of the control channel and the common signal are equal. It should be understood that the threshold values in this application may be 24, 48, 96, 144, etc., or any other value that can achieve the purpose of the invention in this application, and the application is not limited thereto.
Example 2
With reference to example 1, this example mainly describes that the UE determines the adjustment amount according to information (multiplexing pattern of control channel) indicated by a common signal, and/or the network device indicates the adjustment amount through the information (multiplexing pattern of control channel) indicated by the common signal.
The UE determines a multiplexing Pattern of a control channel according to information indicated by a common signal (e.g., information indicated by a PBCH), and the UE determines the adjustment amount according to the multiplexing Pattern of the control channel. That is, when the multiplexing pattern of the control channel includes a first type of multiplexing pattern, the adjustment amount includes any one or more of a first adjustment range, a first adjustment direction, and a first adjustment amount; the multiplexing pattern of the control channel comprises a second type of multiplexing pattern, and the adjustment amount comprises any one or more of a second adjustment range, a second adjustment direction and a second adjustment value. The first type of multiplexing pattern comprises a control resource set/control channel of a control channel and common signal frequency division multiplexing, and the second type of multiplexing pattern comprises the control resource set/control channel of the control channel and common signal time division multiplexing. Wherein the first adjustment value (e.g., 6bB) is greater than the second adjustment value (0 dB). Wherein the first adjustment range (e.g., [0, +12] dB) includes a first maximum adjustment value (e.g., 12dB) that is greater than or equal to a second maximum adjustment value (6dB) included in the second adjustment range (e.g., [ -6, +6 ]). Wherein the first adjustment direction (e.g., upward adjustment) is opposite the second adjustment direction (e.g., downward adjustment), or the first adjustment direction (e.g., upward adjustment and/or no adjustment) is partially opposite the second adjustment direction (e.g., downward adjustment and/or no adjustment). It should be understood that the above adjustment range, adjustment direction or adjustment value is only an example, and may be other ranges, values or directions, which is not limited in this application.
Take three patterns (Pattern) shown in fig. 2 as an example, wherein Pattern 1: the SSB and the control resource set (e.g., RMSI core) of the control channel are located at different times, and the transmission bandwidth of the SSB overlaps with the transmission bandwidth of the control resource set (e.g., RMSI core) containing the control channel; pattern 2: the SSB and the control resource set (such as RMSI CORESET) of the control channel are positioned at different time, and the transmission bandwidth of the SSB is not overlapped with the transmission bandwidth of the control resource set (such as RMSI CORESET) containing the control channel; pattern 3: the SSB and the control resource set (e.g., RMSI core) of the control channel are located at the same time, and the transmission bandwidth of the SSB does not overlap with the transmission bandwidth of the control resource set (e.g., RMSI core) containing the control channel. The first type of multiplexing Pattern may include Pattern2 or Pattern3, and the second type of multiplexing Pattern may include Pattern 1. Considering that the size of the control channel resources actually configurable by the network device and the (physical) downlink shared channel (PDSCH) resources corresponding to the control channel resources is limited under the multiplexing patterns of different control channels, for example, for the case that the multiplexing Pattern of the control channel is Pattern2 or Pattern3 (control resource set/control channel of the control channel and SSB frequency division multiplexing), in the initially activated bandwidth, the number of resources left available for control channel transmission except for SSB is limited, therefore, under the Pattern2 or Pattern3, the network device may enhance coverage by some compensation on transmission power, optionally, the power adjustment range of the control channel and the synchronization signal may be [0, +12] dB, or the adjustment direction may be adjusted upward. Whereas for Pattern1 (control resource set of control channel/control channel and SSB time division multiplexing), the number of resources available for PDCCH transmission is relatively large, and therefore the adjustment amount of the control channel compared to the common signal is relatively small, alternatively, the power adjustment range of the control channel and the synchronization signal is [ -6, +6] dB, or the adjustment direction may be downward adjustment.
Example 3
With reference to examples 1 and 2, this example mainly describes that the UE determines the adjustment amount according to the information indicated by the common signal (subcarrier spacing of control channel) and the information of the common signal (subcarrier spacing of common signal), and/or the network device indicates the adjustment amount through the information indicated by the common signal (subcarrier spacing of control channel) and the information of the common signal (subcarrier spacing of common signal).
At a certain time, the network device may transmit some other signals besides the common signal block, the control channel (signal) and the control resource set of the control channel (e.g., RMSI and RMSI core), such as a channel state information-reference signal (CSI-RS), a PDSCH of some connected UEs, and the like, and usually the entire initially activated bandwidth block is occupied. The control channel and common signal block may have different subcarrier spacing (SCS) for actual transmission. For example, the current NR supported SSB and RMSI subcarrier spacing combinations include: { SSB SCS, RMSI SCS } { {15,15}, {15,30}, {30,15}, {30,30}, {120,60},
{120,120}, {240,60}, {240,120} } kHz. Under the same initially activated bandwidth block, the larger the subcarrier spacing is, the smaller the total number of resource units supportable under the bandwidth block is, and conversely, the smaller the subcarrier spacing is, the larger the total number of resource units supportable under the bandwidth block is. The amount of adjustment of the transmission power of the control channel and common signals (at each resource element) is related to the subcarrier spacing of the control channel and common signals (e.g., SSB and RMSI) for a given total power of the network device. Wherein the subcarrier spacing of the common signal is obtained according to the information of the common signal (itself), for example, the SSB SCS is obtained by the UE blind detection. The subcarrier spacing of the control channel is obtained by the UE based on the information indicated by the common signal, e.g., the RMSI and/or the SCS of the control channel of the RMSI is MIB configured.
Alternatively, the adjustment amount of the transmission power may be a ratio of a subcarrier spacing of the common signal to a subcarrier spacing of the control channel (for example, SQRT — SCS _ SSB/SCS _ PDCCH, where SCS _ SSB is a subcarrier spacing value of SSB and SCS _ PDCCH is a subcarrier spacing value of the control channel). Alternatively, the adjustment amount of the transmission power may be a ratio of a subcarrier spacing of the control channel to a subcarrier spacing of the common signal (e.g., SQRT ═ s)
SCS _ PDCCH/SCS _ SSB, where SCS _ PDCCH is the subcarrier spacing value of the control channel and SCS _ SSB is the subcarrier spacing value of SSB).
The unit of the power adjustment can be expressed in dB, for example, when the ratio is 2, the corresponding power adjustment is 3dB, when the ratio is 4, the corresponding power adjustment is 6dB, when the ratio is 1/2, the corresponding power adjustment is-3 dB, and so on.
Example 4
With reference to examples 1, 2 and 3, this example mainly describes that the UE determines the adjustment amount according to the information indicated by the common signal (transmission resource of control channel) and the information of the common signal (transmission resource of common signal), and/or the network device indicates the adjustment amount through the information indicated by the common signal (transmission resource of control channel) and the information of the common signal (transmission resource of common signal).
At a certain moment, when the network device is transmitting the common signal block, no other signal (e.g., channel state information-reference signal,
CSI-RS), PDSCH of some connected-state UEs, etc.), the network device may apply the total transmit power only to the set of control resources of the common signal or control channel, and thus the adjustment value of the control channel to the transmission power of the common signal (at each resource element) is related to the transmission resources of the common signal (i.e., the total number of resource elements of the common signal) and the transmission resources of the control channel (i.e., the total number of resource elements of the control channel). The total number of resource units of the common signal refers to the total number of resource units occupied by the common signal in a time unit (e.g., in one slot, mini-slot, one frame, one half frame, and one OFDM symbol). The total number of resource units of the control channel refers to the total number of resource units occupied by the control channel within one time unit. Alternatively, the adjustment amount of the transmission power may be a ratio of the transmission resource of the control channel to the transmission resource of the common signal. Optionally, the adjustment amount of the transmission power may also be a ratio of the transmission resource of the common signal to the transmission resource of the control channel. The unit of the power adjustment can be expressed in dB, for example, when the ratio is 2, the corresponding power adjustment is 3dB, when the ratio is 4, the corresponding power adjustment is 6dB, when the ratio is 1/2, the corresponding power adjustment is-3 dB, and so on.
It should be appreciated that the method of any of examples 1-4 may be used in combination of two or more to more accurately determine the amount of adjustment to the transmission power of the control channel. For example, the adjustment amount of the transmission power may be determined according to the multiplexing pattern of the control channel, the subcarrier interval of the control channel. For example, the adjustment amount of the transmission power may also be determined according to the multiplexing pattern of the control channel, the subcarrier interval of the control channel, and the subcarriers of the common signal. (for example, the adjustment range of the transmission power corresponding to Pattern1, { SSB SCS, RMSI SCS } - {120,60} kHz is [ -6, +6] dB, and the adjustment range of the transmission power corresponding to Pattern2, { SSB SCS, RMSI SCS } - {120,60} kHz is [0, +12] dB.
Example 5
With reference to examples 1-4, this example mainly describes that the UE determines the adjustment amount according to the information indicated by the common signal (adjustment information indicated by common signal display), and/or the network device indicates the adjustment amount through the information indicated by the common signal (adjustment information indicated by common signal display).
Optionally, the adjustment information may include a power adjustment range and/or an adjustment value of the control channel, and may also include a power adjustment direction of the control channel, and the like. The adjustment information may be explicitly indicated to the UE through the MIB in the SSB, or may be explicitly notified to the UE through system information, such as RMSI, and the method for notifying the UE through RMSI is applicable to other PDCCH core sets except for RMSI core set, such as paging PDCCH, OSI PDCCH, or RAR PDCCH.
For example, the adjustment information may be indicated by a small number of reserved (reserved) bits (bits) in PBCH or RMSI. The PBCH has 4 reserved bits in the high frequency and 2 reserved bits in the low frequency. The indication adjustment range and/or adjustment value may be displayed with 1 to 2 bits of the reserved bits in the PBCH. The adjustment direction may also be indicated with 1 reserved bit in PBCH.
The method of example 5 may be further combined with any one or more of the methods of examples 1 to 4, and the adjustment amount may be indicated by means of implicit + display joint indication, which is not specifically limited herein. For example, the UE determines the power adjustment range of the control channel to be one of [0, +12] dB, or [ -3, +9] dB based on the CORESET size, and then indicates which of [0, +12] dB, or [ -3, +9] dB is specified according to 1 reserved bit in the PBCH or RMSI.
In the following, the network device or the UE related to the present application is divided into function transmission units by combining one or more control channel transmission methods, for example, each function transmission unit may be divided corresponding to each function, or two or more functions may be integrated into one transmission unit.
