Detailed Description

In the embodiment of the invention, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present application means two or more, and other adjectives are similar.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In order to facilitate understanding of the aspects of the present application, the description will be given with respect to the related matters related to the present application.

The New air interface (NR) Rel-15 standard standardizes synchronization signal blocks (Synchronization signal/PBCH block, SSB) to support UE access and transmission, each SSB consists of a primary synchronization signal (Primary Synchronization Signals, PSS), a secondary synchronization signal (Secondary Synchronization Signals, SSS) and a physical broadcast channel (Physical Broadcast Channel, PBCH) to form 4 orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols with a time domain size of 4 and 20 physical resource blocks (Physical Resource Block, PRB) with a frequency domain size.

Meanwhile, the network side equipment realizes one-time beam scanning by sending an SSB burst set (SSB burst) to cover the whole service range of the cell. According to the NR protocol, the transmission time of each SSB Burst is completed within 5ms, and each SSB Burst contains L SSBs, and for FR1, L is 8 at maximum; for FR2, lmax is 64, one transmit beam per SSB, as shown in fig. 1. The 5G protocol supports {5,10,20,40,80,160} ms, and a User Equipment (UE) defaults to 20ms for SSB default transmission period, and the UE can obtain the actual transmission period of SSB after completing initial cell search.

The UE obtains the specific configuration of random access time (RACH occision, RO) by decoding a system message block (System Information Block, SIB) signaling issued by the base station in the current cell, and initiates contention-based random access to the cell where the UE is currently residing, namely, sends a Preamble based on a ZC sequence to the base station on the RO.

If the UE has beam reciprocity, the UE determines a transmit beam for transmitting the Preamble via the receive beam. If the UE does not have beam reciprocity, the UE can only transmit the Preamble in an attempt-by-attempt manner, i.e., upstream beam scanning.

The base station side transmits Preamble signals to the UE through receiving beam forming. If the beam reciprocity at the base station side is not established, the base station needs to try a plurality of possible receiving beams, namely, receive signals in a receiving beam scanning mode. If the base station side beam reciprocity is true, the base station may determine the corresponding receive beam from the transmit beam.

The UE has determined the associated SSB before transmitting the Preamble, the transmit beam of which is the best candidate for the base station to receive the beam. But at this time, the UE does not notify the association SSB corresponding to the Preamble sent by the base station.

The solution given by NR is to establish an association relationship between RO subsets and preambles and SSBs, and after detecting an SSB, UE selects RO and preambles from the RO subsets and preambles associated with the SSB. The RO and Preamble selected by the UE implicitly indicate the SSB detected by the UE. The base station may determine the receive beam using the transmit beam of its associated SSB when detecting a particular Preamble on a particular PRACH resource.

The association period of SSB mapping to RO means that at least one round of SSB-to-RO mapping is completed within the period, so that each actually transmitted SSB is mapped to at least one RO, the association period of SSB mapping to RO is an integer multiple of the PRACH period (PRACH configuration period), and the multiple is the minimum value of the values listed in table 1. Wherein the association period is calculated starting from system frame 0. After one round of SSB to RO mapping is completed in one association cycle, the next round of mapping is continued until the remaining ROs are insufficient to complete one round of SSB to RO mapping. If the remaining ROs are not sufficient to complete a round of SSB-to-RO mapping, then the remaining ROs are an invalid RO set. All ROs within the invalid RO set cannot be associated to SSBs and cannot be used for PRACH transmission. Since the number of valid ROs contained within an association period of one SSB mapping to an RO is variable under some configuration conditions, the NR protocol further defines a time domain repetition period of the association period of the SSB mapping to the RO by the association pattern period. The maximum value of the association pattern period of SSB mapping to RO is 160 milliseconds.

Table 1: PRACH configuration period correspondence of SSB mapping to association period of RO

The association relationship of the SSB mapping to the RO supports three cases of 1 to 1, multiple pairs of 1 and 1 to multiple pairs, and the specific mapping rule is as follows: the UE reads the high-level parameters and obtains two parameters N and R, wherein N represents the number of SSB (secure digital broadcasting) associated with one RO; and R represents the number of continuous preambles based on contention random access corresponding to each SSB. For the contention-based random access procedure (CBRA), the order in which SSB indexes are mapped to RO indexes is as follows:

first, arranging in an RO according to the ascending order of Preamble index;

Second, an ascending order of frequency resource indexes for a plurality of frequency division multiplexed ROs;

thirdly, according to the increasing sequence of the time resource indexes of the time division multiplexing (RO) in one PRACH time slot;

Fourth, the PRACH slots are arranged in ascending order of their index.

Fig. 2 is an example of association of SSBs with ROs, assuming that each SSB burst contains L SSBs, the number of frequency division multiplexing ROs msg 1-fdm=4, i.e., msg1-FDM is used to indicate the number of ROs on the frequency domain resource. At this time, n=1/4, meaning that one RO is associated with 1/4 SSBs, i.e., one SSB is associated with 4 ROs. Each block in FIG. 2 represents 1 RO opportunity, and SSB1/2/3//4/5/6/7/8 on each block represents that the RO is associated with SSB1/2/3// 4/5/6/7/8.

The time domain resource location of the RO may be obtained from tables 6.3.3.2-2, 6.3.3.2-3, 6.3.3.2-4 in the protocol 38.211, a specific example of which is shown in table 2: the frequency range FR1 and the frequency division multiplexing (Frequency Division Duplexing, FDD) configuration determines the time domain resource location of the RO through the table 6.3.3.2-2, and first, the PRACH configuration index (PRACH Configuration Index) parameter is obtained, through which the Preamble format, PRACH configuration period (x), the PRACH frame (y), the PRACH subframe number, the start symbol, the number of PRACH slots in the PRACH subframe, the number of ROs in the PRACH slot, the duration of the RO, etc. can be determined accordingly. For table 6.3.3.2-4, the PRACH configuration index may correspondingly determine Preamble formats Preamble format, PRACH configuration period (x), PRACH frame (y), PRACH slot number, start symbol, number of PRACH slots in 60kH slots, number of ROs in PRACH slots, duration of ROs, etc.

Table 2: FR1 and FDD/supplemental uplink random access configuration

By analyzing the tables 6.3.3.2-2, 6.3.3.2-3, 6.3.3.2-4 in the protocol 38.211, for FDD and time division multiplexing (Time Division Duplexing, TDD) of FR1 and TDD RO configuration of FR2, the number of RO's in PRACH configuration period of 80ms, 160ms, etc. is small, the number of RO's in PRACH configuration period of 10ms, 20ms, etc. is large but scattered, illustrated by FDD of FR1, as shown in Table 3.

In order to enable more UEs (especially idle UEs) to perform initial access in the power saving state of the network and enable the base station gNB to be in the deep sleep DEEP SLEEP state in the period without RO, a solution is needed in which the number of ROs is sufficient and the ROs are concentrated when the configuration is large at PRACH configuration period.

If the first time index is the first subframe number, the first parameter is a subframe offset period, and the second time index is the second subframe number.

If the first time index is the first time slot number, the first parameter is the time slot offset period, and the second time index is the second time slot number.

As noted above, the first time index may be a first radio frame number, a first subframe number, or a first slot number.

In the case that the first time index is the first radio frame number, determining the first radio frame number based on the PRACH configuration index (i.e., PRACH configuration index) may specifically include:

The PRACH frame (i.e., the first radio frame number) is determined according to n _SFN modx = y, where x is used to represent the PRACH period and the PRACH configuration index has a corresponding PRACH period, see, for example, table 2 above.

As an alternative embodiment, step 2 a) above may comprise 2 a-1) and/or 2 a-2):

2 a-1) determining a second time index based on the first time index and a second parameter, the second parameter comprising at least one value, the second parameter being determined by the first parameter;

In the case where the first time index is the first subframe number or the first slot number, this may be: determining Sn_f according to Sn and t, wherein Sn is a first subframe number or a first time slot number, t is a second parameter, t E {0,1, …, as-1}, and when Sn is the first subframe number, as is a subframe offset time period; when Sn is the first slot number, as is the slot offset period, and t may be determined from As, i.e., the second parameter is determined by the first parameter.

Specifically, sn_f is determined from Sn and t, one possible method of which is as follows:

Sn f = Sn + t, or sn_f= (sn+t) mod L;

Wherein t is {0,1, …, as-1}; l is the number of subframes or slots within one PRACH frame.

In the case where the first time index is the first radio frame number, y_f may be determined according to y and Af, where y is the first radio frame number, t1 is the second parameter, t1 e {0,1, …, af-1}, af is the radio frame offset period, and t1 may be determined according to Af, i.e., the second parameter is determined by the first parameter.

Specifically, y_f is determined according to y and Af, one possible method is as follows:

y _ f = y + t1, or y_f= (y+t1) mod L1;

wherein, t1 ε {0,1, …, af-1}; l1 is the period configuration length of the PRACH period.

2 A-2) determining the second time index from the first time index and the first parameter, the first parameter comprising at least one value.

In the case where the first time index is the first subframe number or the first slot number, this may be: determining Sn_f according to Sn and As, wherein Sn is a first subframe number or a first time slot number, and when Sn is the first subframe number, as is a subframe offset time period; when Sn is the first slot number, as is the slot offset period.

Specifically, sn_f is determined from Sn and As, one possible method of which is As follows:

sn f = Sn + As, or sn_f= (sn+as) mod L;

where as= {0,1, …, N }, where N is a specific number less than or equal to L, L is the number of subframes or slots within one PRACH frame.

Here, as can be directly configured As {0,1, …, N }

In the case where the first time index is the first radio frame number, here, y_f may be determined according to y and Af, where y is the first radio frame number and Af is the radio frame offset period.

Wherein af= {0,1, …, N1}; where N1 is a specific number less than or equal to L1, L1 is the period configuration length of the PRACH period.

Here, af may be directly configured as {0,1, …, N1}.

As an alternative embodiment, in case the first parameter comprises a first scale factor, step 301, determining the random access occasion RO according to the first parameter comprises:

determining the number of ROs on the initial frequency domain resource; and determining the number of RO on the final frequency domain resource according to the number of RO on the initial frequency domain resource and the first scale factor.

Here, the initial number of ROs on the frequency domain resource refers to the number of ROs on the existing frequency domain resource, e.g., the number of ROs on the existing frequency domain resource is determined by msg 1-FDM.

It should be appreciated that the first scale factor is used to determine possible transmission opportunities that the first signal occupies in the frequency domain.

Optionally, the first scale factor is a scale factor of msg1-FDM, and the first scale factor is used for determining the number of ROs on the final frequency domain resource on the basis of msg1-FDM, and determining the number of ROs multiplexed on the frequency domain by the scale factor of msg1-FDM, thereby increasing the number of ROs configured by FDM.

In an alternative implementation, step 301, determining the random access opportunity RO according to a first rule includes:

A valid RO is determined according to a first rule.

In a first implementable manner, the first rule is: and the RO in M PRACH periods in the N PRACH periods in the first time period is an effective RO, wherein the values of the first time period and the M are determined through the second parameter, N is greater than or equal to M, and M, N are positive integers.

The main idea of the method is as follows: when the PRACH period is small, only M PRACH periods are valid (i.e., ROs in these periods are valid) for a fixed period of time (e.g., the first period of time) or for N PRACH periods included in the ringer SSB period, thereby disabling ROs in subsequent PRACH periods. In this way, by configuring a small PRACH period, the function that a sufficient and concentrated RO exists in the period before the first period (for example, 160 ms), and the RO in the later period is invalid, so that not only can more UEs perform initial access, but also the gNB can be in a deep sleep DEEP SLEEP state when no RO is configured.

The main idea of the method is as follows: in this way, the function that a sufficient and concentrated number of ROs exist in a period of time before a first period of time (for example, 160 ms) can be realized, and ROs in a later period of time are invalid, so that not only can more UEs perform initial access, but also the gNB can be in a deep sleep DEEP SLEEP state when no RO configuration exists.

Example 1: determining RO from sub-frame frequency shift period or slot offset period

UE side:

Step 1: the UE determines the RO, wherein the resource position corresponding to the RO is the resource position for transmitting the first signal;

here, the first signal may be a random access preamble. Of course, the first signal may be other uplink signals. The resource locations of the first signal include time domain resource locations and/or frequency domain resource locations for transmitting the first signal.

The specific steps included in the step 1 are as follows:

① The UE determines a first subframe number or a first time slot number;

specifically, the existing method may be multiplexed to determine the first subframe number or the first slot number. For example, one or more starting PRACH subframes/slots (i.e., first subframe or first slot, denoted as Sn) are determined within the PRACH period, as follows:

Determining a PRACH frame according to n _SFN modx = y;

one or more Sn are determined within the PRACH frame according to the PRACH configuration index.

② The UE determines a subframe offset period or a slot offset period.

Here, the subframe offset period or the slot offset period may be determined by a system message configuration, a higher layer signaling configuration, or by the number of one or more first subframes or first slots Sn corresponding to the PRACH configuration index. Wherein the subframe offset period or the slot offset period may be denoted As.

The present embodiment is not limited to how to determine the value of the subframe offset period or the slot offset period.

In the case where As is determined by the number of one or more first subframes or first slots Sn corresponding to the PRACH configuration index, specific examples are As follows:

As=l/number of Sn in one PRACH frame; where L is the number of subframes or slots within one PRACH frame.

For example, 2 Sn (e.g., subframe numbers 1 and 6) may be configured in an existing PRACH frame, where As may be equal to 5.

③ The UE determines the RO according to the subframe offset period or the slot offset period.

For example, the UE determines a second subframe number according to the first subframe number and the subframe offset period; and determining the RO based on the second subframe number, wherein the RO comprises the RO in the second subframe corresponding to the second subframe number.

Here, the first subframe may be one subframe or a plurality of subframes, and the subframe offset period includes at least one subframe. The number of second subframes corresponding to the second subframe number determined according to the first subframe number and the subframe offset period may be greater than the number of first subframes.

For another example, the UE determines a second slot number according to the first slot number and the slot offset period; and determining the RO based on the second time slot number, wherein the RO comprises the RO in the second time slot corresponding to the second time slot number.

Here, the first slot may be one slot or a plurality of slots, and the slot offset period includes at least one slot. The number of second slots corresponding to the second slot number determined from the first slot number and the slot offset period may be greater than the number of first slots

Sn_f (second subframe number/second slot number) is determined from Sn (first subframe number/first slot number) and As (subframe offset period/slot offset period), one possible method is As follows:

Sn f = Sn + t, or sn_f= (sn+t) mod L;

In the method, as refers to the maximum value of the subframe offset period or the maximum value of the slot offset period.

Another possible method is as follows:

sn f = Sn + As, or sn_f= (sn+as) mod L;

wherein As epsilon {0,1, …, N }; l is the number of subframes or slots within one PRACH frame, and N is a specific number less than or equal to L.

That is, the subframe offset period/slot offset period includes a plurality of possible values. It is understood that the subframe offset period/slot offset period is a set. The multiple possible values included in the subframe offset period/slot offset period may be obtained by direct configuration.

As shown in fig. 4, the system frame SFN with stripe filling is a PRACH frame in the PRACH period, the subframe/slot with stripe filling is a first subframe or a first slot, and the subframe offset period/slot offset period is in the dashed frame, for example, the first subframe number/first slot number is 0, as is configured to be 5, the value of t is {0,1,2,3,4}, and further the second subframe number is determined to be 0,1,2,3,4.

Step 2: and the UE transmits a first signal on the resource position corresponding to the RO.

GNB side:

Step 1: the gNB determines the RO, and the resource position corresponding to the RO is the resource position for transmitting the first signal;

step 2: the gNB receives the first signal at the resource location corresponding to the RO.

The specific execution steps of the gNB are similar to those of the UE side, and are not repeated here.

In this embodiment, an additional subframe offset period/slot offset period is added on the basis of the existing PRACH subframe/slot (i.e., the first subframe or the first slot in the present application) in the PRACH period, and a second subframe or a second slot is determined, where a resource location corresponding to RO included in the second subframe or the second slot is used for transmitting the first signal, so that the number of PRACH subframes/slots in the PRACH period is increased, and the number of ROs is increased, thereby implementing that more UEs can initially access in a network in a power saving state, and enabling the base station gNB to be in a deep sleep DEEP SLEEP state when no RO configuration exists.

Example 2: determining an RO according to the radio frame offset time period;

UE side:

the specific steps included in the step 1 are as follows:

① The UE determines a first wireless frame number;

Specifically, the existing method may be multiplexed to determine the first radio frame number. For example, one or more starting PRACH frames (i.e., a first radio frame, denoted as y) are determined within the PRACH period, as follows:

the PRACH frame is determined according to n _SFN modx = y.

② The UE determines a radio frame offset period.

Here, the radio frame offset period may be configured by a system message or a higher layer signaling, or by the number of one or more first radio frames y corresponding to the PRACH configuration index, or by the PRACH period, or by the length of the SSB period, or by the period that the gNB is on and/or off, or by the length of time that the gNB is on and/or off. The radio frame offset period may be denoted by Af.

The present embodiment is not limited as to how to determine the value of the radio frame offset period.

For example, if Af is determined by the PRACH period, if the PRACH period=160 ms, af=4; PRACH period=80 ms, af=2.

③ The UE determines the RO according to the radio frame offset period.

For example, the UE determines a second radio frame number according to the first radio frame number and the radio frame offset period; and determining the RO based on the second radio frame number, wherein the RO comprises the RO in the second radio frame corresponding to the second radio frame number.

Here, the first radio frame may be one radio frame or a plurality of radio frames, and the radio frame offset period includes at least one radio frame. The number of second radio frames corresponding to the second radio frame number determined according to the first radio frame and the radio frame offset period may be greater than the number of first radio frames.

Y_f (second radio frame number) is determined from y (first radio frame number) and Af (radio frame offset period), one possible method is as follows:

y _ f = y + t1, or y_f= (y+t1) mod L1;

In the method, af refers to the maximum value of the radio frame offset period.

Another possible method is as follows:

y_f=y+af, or y_f= (y+af) mod L1;

That is, the radio frame offset period includes a plurality of possible values. It is understood that the radio frame offset period is a set. The plurality of possible values included in the radio frame offset period can be obtained by direct configuration.

As shown in fig. 5, the striped filled system frame SFN is a PRACH frame within the PRACH period and within the dashed box is a radio frame offset period. For example, the first radio frame number is 0, af is configured to be 4, t1 has a value {0,1,2,3}, and the second radio frame number is determined to be 0,1,2,3.

GNB side:

The embodiment determines the second radio frame by adding an additional radio frame offset period/time slot offset period on the basis of the existing PRACH frame (i.e. the first radio frame in the present application) in the PRACH period, where the resource location corresponding to the RO included in the second radio frame is used for transmitting the first signal, so as to increase the number of PRACH frames in the PRACH period and increase the number of ROs, thereby implementing initial access for more UEs in the network in a power saving state, and enabling the base station gNB to be in a deep sleep DEEP SLEEP state when no RO configuration exists.

Example 3: determining valid ROs based on PRACH period

UE side:

step 1: the UE determines an effective RO, and the resource position corresponding to the effective RO is used for transmitting a first signal; is a resource location of (1);

the specific steps included in the step 1 are as follows:

① : the UE determines that RO in M PRACH periods in N PRACH periods is effective RO;

alternatively, the RO is valid for M PRACH periods, including N PRACH periods, in a fixed period (first period) or a ringer SSB period, by system message notification or configuration, or by higher layer signaling notification or configuration, or by protocol convention, where N is greater than or equal to M, which may be equal to 1, as shown in fig. 6.

Alternatively, RO is valid for M PRACH periods, including N PRACH periods, for a fixed period of time or for a ringer SSB period, where the value of M may be related to the length of the SSB period; the SSB period is long, and the value of M is large; SSB period is short, and M is small. Or the value of M may be related to the length of DTX on or DTX off; DTX on is long, and M has a large value; DTX on is short, and M has small value.

② : When the gNB is in the DTX on phase, the UE determines that the RO in the PRACH period in the DTX on phase is a valid RO. At this time, RO in PRACH period in DTX off period is invalid.

Here, step ① and step ② are side-by-side schemes.

Step 2: and the UE transmits a first signal at the resource position corresponding to the effective RO.

GNB side:

Step 1: the gNB determines an effective RO, wherein the resource position corresponding to the effective RO is the resource position for transmitting the first signal;

Or the effective RO and DTX on/DTX off, so as to enable more UEs to perform initial access in the network in the power saving state, and enable the base station gNB to be in the deep sleep DEEP SLEEP state when no RO configuration exists.

Or the value of M1 is agreed by the protocol, where the value of M1 may be 1. Or the value of M1 may be related to the length of the SSB period; the SSB period is long, and the M1 value is large; SSB period is short, and M1 takes on a small value. Or the value of M1 may be related to the length of DTX on or DTX off; DTX on is long, and M1 has a large value; DTX on is short, and M1 takes on a small value.

Step 1-2: at least a portion of the ROs are valid based on M2 SSBs mapped to ROs during a first time period or a ringer SSB period.

Alternatively, the value of M2 is notified or configured by a system message, or is notified or configured by a higher layer signaling, or is agreed by a protocol, where the value of M2 may be 1.

Or at least part of the correlation period of mapping M2 SSBs to the RO is effective in a fixed time period or a ringer SSB period, and the RO is ineffective in other correlation periods, so that the initial access of more UE is realized under the condition that the network is in a power saving state, and the base station gNB can be in a deep sleep DEEP SLEEP state when no RO configuration exists.

Example 5: the valid ROUE side is determined according to the duration of the valid RO or the duration of the invalid RO:

step 1: determining a valid RO through a first duration T1 or a second duration T2 in a first time period; wherein, the RO in T1 is a valid RO; the RO within T2 is an invalid RO.

Alternatively, the value of T1 or T2 is notified or configured by a system message, or by higher layer signaling, as shown in fig. 8.
