Description

Information transmission method and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method and a terminal.

Background

In a New Radio (NR), a base station may configure a PRACH transmission opportunity (also referred to as a Random Access Channel opportunity (RACH) with multiple Frequency-division multiplexing (FDM)) at a time point (time instance, which is a time duration required for transmitting a Physical Random Access Channel (PRACH) resource and is also referred to as a time domain position for transmitting the PRACH), and is abbreviated as RO herein for simplicity. The number of ROs that can be FDM on a time instance may be: {1,2,4,8}.

There is an association between the RO and the actually transmitted synchronization signal/physical broadcast channel block (SS/PBCH block, sometimes also referred to directly as SS block, synchronization signal block). Multiple SSBs may be associated with a RO, and the number of SSBs associated with a RO may be {1/8,1/4,1/2,1,2,4,8,16 }. For a non-contention random access procedure, there may also be an association between the RO and a Channel State Information-Reference Signals (CSI-RS).

Taking fig. 1 as an example, the number of FDM ROs in one time instance is 8, the number of actually transmitted SSBs is 4, for example, the corresponding SSBs are SSB #0, SSB #1, SSB #2, and SSB #3, and each SSB is associated with 2 ROs, wherein different SSBs are distinguished by different padding. If the UE transmits the PRACH on the RO corresponding to the SSB0, the UE selects one RO from RO #0 and RO #1 for PRACH transmission.

In PRACH transmission, in order to meet the requirements of OCB, the UE may need to transmit a Preamble sequence (Preamble sequence) on multiple ROs. Once the resources on both sides of the CHannel are occupied by the RO for PRACH transmission, the remaining resources are used for transmission of a Physical Uplink Shared CHannel (PUSCH), so that the PUSCH hardly meets the requirements of the OCB.

Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Embodiments of the present invention are described below with reference to the accompanying drawings. The information transmission method and the terminal provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a system adopting a 5th Generation (5G) mobile communication technology (hereinafter, referred to as a 5G system), and those skilled in the art will appreciate that the 5G NR system is only an example and is not a limitation.

In making the description of the embodiments of the present invention, some concepts used in the following description will first be explained.

In a New Radio resource Assisted Access (NR-LAA), before transmitting information, a transmitting node (a base station or a User Equipment (UE, also called a terminal)) needs to perform Clear Channel Assessment (CCA)/enhanced Clear Channel assessment (eCCA) to monitor a Channel, that is, perform Energy Detection (ED), and when Energy is lower than a certain threshold, the Channel is determined to be empty, and then the transmitting node may start transmission. Since the unlicensed frequency band is shared by multiple technologies, this contention-based access method causes uncertainty of the available time of the channel. The fixed-location Reference Signal (RS) configuration in the NR is no longer applicable to the unlicensed band, because when the channel is available, the RS may have missed its transmittable location and cannot transmit it, which may result in failure to properly perform the RS reception and various measurements and evaluations of the wireless channel environment by the RS.

After listening to the channel and determining to be empty, the duration of the UE sending the signal needs to be less than a Maximum Channel Occupancy Time (MCOT).

According to the rules of Occupied Channel Bandwidth (OCB), in the unlicensed band, a transmission node occupies at least 70% (e.g., at least 70% of the entire band is occupied when the channel band is around 60 GHz) or 80% (e.g., at least 80% of the band is occupied when the channel band is around 5 GHz) of the bandwidth of the entire band at each transmission. In uplink transmission, to solve this problem, eLAA introduces interleaved (interleaved) Resource Block (RB) allocation. 100 RBs on a 20MHz bandwidth are evenly divided into 10 interleaved resources (interlaces). Each interlace contains 10 equally spaced Physical Resource Blocks (PRBs). Interlace 0 comprises RB 0, 10, 20 … 90. At the time of scheduling, the UE may be allocated to one or more interlaces.

The random access preamble can be transmitted only on the time domain resource configured by the parameter PRACHConfigurationIndex, the random access preamble can be transmitted only on the frequency domain resource configured by the parameter PRACH-FDM, and the PRACH frequency domain resource n_RAE {0, 1., M-1}, where M equals the higher layer parameter prach-FDM. At the time of initial access, PRACH frequency domain resource n_RAFrom the initial excitationStarting up sequence numbering for lowest frequency RO resource in active uplink bandwidth part (initial active uplink bandwidth part), otherwise, PRACH frequency domain resource n_RANumbering is carried out in an ascending order from the lowest frequency RO resource in an activated uplink bandwidth part (active uplink bandwidth part).

In order to meet the OCB requirement on the unlicensed frequency band, even if the network schedules the uplink PUSCH for the UE by using interlace as a unit, since resources on both sides are occupied by the RO, the frequency domain resources occupied by the PUSCH cannot meet the OCB requirement.

If the network does not use the scheduling method of interlace, for a user with small data volume, for example, using PUSCH transmission of 10 consecutive RBs, the PUSCH transmitted by the UE does not meet the OCB requirement.

When the transmission of the PUSCH does not meet the OCB requirement, the reliability of network communication cannot be guaranteed.

Specifically, as shown in fig. 2, an embodiment of the present invention provides an information transmission method, which is applied to a terminal, and includes:

step 201, when a Physical Uplink Shared Channel (PUSCH) does not meet an Occupied Channel Bandwidth (OCB) rule, mapping an occupied signal on a first resource;

the first resource is a resource except PUSCH in a preset channel bandwidth;

step 202, transmitting the PUSCH and the occupancy signal;

step 202 enables transmission of the PUSCH and the placeholder signal on a specific resource.

It should be noted that the first resource includes a time domain resource and a frequency domain resource.

It should be noted that, in the above scheme, when the PUSCH does not satisfy the OCB rule, the occupied signal is mapped to ensure that the terminal can satisfy the requirement of occupying the bandwidth in the unlicensed frequency band at the time of sending the PUSCH (that is, the OCB rule is satisfied).

It should be further noted that, when the Resource Block (RB) for PUSCH transmission is located in a physical random access channel (RO) resource, the PUSCH is not transmitted on the RO resource, in this case, the PUSCH may also be caused to not meet the OCB rule, and therefore, the step 201 is also required to map the placeholder signal, so that the PUSCH meets the OCB rule.

It should be noted that the RO resource is a resource configured by the network device for physical random access channel transmission.

It should be further noted that the RO resource is included in at least one of the following information:

a subframe, a slot, an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a Resource Block (RB), and a Resource Element (RE).

It should be noted that, in order to meet the OCB requirement, one implementation manner of the network is to use an interlace as a unit to schedule a discrete RB resource for a terminal, and some time-frequency resources scheduled for uplink transmission are RO resources (i.e., resources used for Physical Random Access Channel (PRACH) transmission) configured for system information. In order to guarantee the performance of PRACH transmission, PUSCH is not transmitted on slots, OFDM symbols, RBs, or REs containing ROs.

For example, the resources for PUSCH transmission scheduled by the network are RB #0, RB #10, RB #20 … … RB #90, and the RO resources configured by the network include RB #0 to RB #11 and RB #84 to RB #95, then RB #0, RB #10, RB #90 are not used for PUSCH transmission.

It should be further noted that the terminal may obtain the time-frequency resource occupied by the RO through the system information.

It should be noted that the first resource includes: and the PUSCH is transmitted in the frequency domain resource on the same time resource.

It should be noted that the time resources include: at least one of a slot, a subframe, an OFDM symbol.

This way, the mapping of the occupied signal is preferably performed by using the frequency domain resource belonging to the same time resource as the PUSCH.

Further, the first resource comprises at least one RO resource.

It should be noted that, although no transmission with PUSCH is used on the RO resource, the RO resource mapping placeholder signal may be borrowed, and the RO resource mapping placeholder signal is used for a non-random access purpose (i.e., is only used for placeholder), so that the PUSCH satisfies the OCB rule.

It should be further noted that the occupancy signal includes: a pseudo-random signal.

Specifically, the pseudo-random signals include, but are not limited to: at least one of a ZC sequence, an m-sequence (i.e., the longest linear feedback shift register sequence), a Gold sequence, a sequence of a predetermined set, and a signal conforming to a predetermined distribution rule.

It should be noted that the pseudo-random signal may further include: the constant amplitude zero auto-correlation (CAZAC) sequence includes, in addition to a ZC sequence, a Frank sequence, a Golomb polyphase sequence, and a Chirp sequence, for example, the pseudo random signal may further include: at least one of a Frank sequence, a Golomb polyphase sequence, and a Chirp sequence.

The appointed set comprises a preset number of target sequences, and specifically, the target sequences comprise sequences except ZC sequences, m sequences and Gold sequences.

It should be noted that the signal according to the preset distribution rule may be: a random signal obeying a normal distribution with a mean of 0 and a variance of a preset increment.

Further, when the pseudo-random signal comprises a ZC sequence, a set of a root sequence index and a cyclic shift value of the ZC sequence is a preset set;

the preset set includes: sequences other than the preamble sequence preset for transmission on the Physical Random Access Channel (PRACH) (for example, the sequence included in the preset set is different from the sequence in the 64 preamble sequences) or partial sequences in the preamble sequence preset for transmission on the PRACH (for example, the preset set includes partial sequences in the 64 preamble sequences).

Further, when the pseudo random signal includes a ZC sequence, at least one of a root sequence index and a cyclic shift value of the ZC sequence is indicated by preset information;

wherein the preset information includes: at least one of system information, Radio Resource Control (RRC) information, media access control layer control element (MAC CE), and downlink control information.

For example, the network device may notify the root sequence index and the cyclic shift value of the ZC sequence to the terminal through system information, RRC information, MAC CE, or downlink control information.

In the bandwidth of the channel, there are 8 ROs multiplexed in FDM manner, the PUSCH scheduled by the network does not meet the requirement of OCB because the rate matching needs to be performed on the RO resources (that is, the PUSCH is not transmitted on the RO resources), and in order to meet the requirement of OCB, the terminal may simultaneously select to transmit the ZC sequence on at least one RO resource when the PUSCH transmitted does not meet the requirement of OCB, and the length of the ZC sequence may be the same as the length of the preamble sequence of the PRACH, for example, the lengths are 839 and 139; it should be noted that, in this case, the ZC sequence transmitted on at least one RO resource is used for non-random access purposes (for placeholders).

It should be noted that, in the embodiment of the present invention, when the PUSCH does not satisfy the OCB rule, the occupied signal is mapped on the resource except the PUSCH in the preset channel bandwidth, and then the transmission of the resource of the PUSCH and the occupied signal is implemented, so that the transmission of the PUSCH satisfies the requirement of the OCB, and the reliability of network communication can be ensured.

As shown in fig. 3, an embodiment of the present invention further provides a terminal 300, including:

the mapping module 301 is configured to map an occupied signal on a first resource when a physical uplink shared channel PUSCH does not meet an occupied channel bandwidth OCB rule, where the first resource is a resource other than a PUSCH in a preset channel bandwidth;

a transmission module 302 configured to transmit the PUSCH and the occupancy signal.

Further, when the resource block RB of the PUSCH transmission is located in the RO resource of the physical random access channel transmission opportunity, the PUSCH is not transmitted on the RO resource.

Specifically, the RO resource is included in at least one of the following information:

a subframe, a slot, an orthogonal frequency division multiplexing, OFDM, symbol, a resource block, and a resource element.

Further, the first resource includes: the frequency domain resources on the same time resources as the same phase as the PUSCH are transmitted.

Optionally, the first resource includes: at least one RO resource.

Optionally, the occupancy signal comprises: a pseudo-random signal.

Further, the pseudo-random signal includes: at least one of a ZC sequence, a longest linear feedback shift register sequence, a Gold sequence, a sequence of an appointed set and a signal according with a preset distribution rule;

wherein, the appointed set comprises a preset number of target sequences.

Specifically, when the pseudo-random signal includes a ZC sequence, a set of a root sequence index and a cyclic shift value of the ZC sequence is a preset set;

the preset set includes: sequences except for the preset preamble sequence used for transmitting on the physical random access channel PRACH or partial sequences in the preset preamble sequence used for transmitting on the PRACH.

Specifically, when the pseudo-random signal includes a ZC sequence, at least one of a root sequence index and a cyclic shift value of the ZC sequence is indicated by preset information;

wherein the preset information includes: at least one of system information, radio resource control RRC information, media access control layer control element MAC CE and downlink control information.

It should be noted that the terminal embodiment is a terminal corresponding to the information transmission method applied to the terminal side, and all implementations of the above embodiments are applicable to the terminal embodiment, and the same technical effects as those of the terminal embodiment can also be achieved.
