Description

Information indicating method and device

technical field

Embodiments of the present invention relate to the field of communication technologies, and in particular, to a method and device for indicating information.

Background technique

In a wide coverage scenario, repeated transmission is one of the means to expand the signal coverage.

In Narrow Band Internet of Things (NB-IoT), Narrowband Primary Synchronization Signal (NPSS), Narrowband Secondary Synchronization Signal (NSSS) and Narrowband Physical Broadcast Channel (Narrowband PhysicalBroadcast Channel, NPBCH) have been completely redesigned, including resource mapping and transmission period, to support multiple repeated transmissions required by NB-IoT users.

The fifth-generation (5G) new radio (NR) design is mainly focused on the Enhanced Mobile Broadband (eMBB) scenario, and has not yet addressed the need for wide coverage and large connections. Targeted design.

Referring to FIG. 1, the figure illustrates a synchronization/physical broadcast channel signal block (SS/PBCH block, hereinafter referred to as SSB), including PSS, SSS signal and PBCH). According to the design of the relevant NR, the PSS and SSS signals can be combined with a period of 20ms all the time, but the PBCH can only be combined four times within 80ms according to the assumption of the maximum period of 80ms.

The assumption that a version 15 (R15) terminal searches for synchronization and broadcast signals at a cycle of 20ms during initial access can only get a combined gain of 6dB at most. It is difficult to meet the coverage enhancement needs of all wide-coverage users.

In the embodiment of the present invention, the terminal combining is clearly indicated for the terminal to perform SS/PBCH block combining without blind detection and attempted combining, which meets the coverage enhancement requirements of all wide-coverage users.

In order to ensure the coverage of mMTC terminals, based on the existing NR design, the base station may configure multiple repeatedly transmitted SS/PBCH blocks for the terminal to receive and combine PBCH, but the terminal may not know which SSs can be combined during the initial search. If the /PBCH block is combined according to the existing period, a maximum coverage enhancement gain of 6dB can be obtained. In order to obtain a larger coverage enhancement gain, additional instructions need to be given to the terminal.

In the embodiment of the present invention, a specific repetition indication signal or channel is introduced into the NR to indicate the merging and merging formats of the SS/PBCH blocks.

Specifically, the format of SS/PBCH block repetition can be divided into the following categories:

Type 1: 80ms.

Type 2: Different 20ms within 80ms can be combined.

Type 3: Different 5ms within 20ms can be combined.

It is equivalent to informing the terminal of the transmission period of the SS/PBCH block in advance through a new indication signal, such as 5ms, 10ms and 20ms, corresponding to 4, 2 and 1 combining within 20ms respectively.

Type 4: Different SS/PBCH block indices within 5ms can be combined.

For the above merged format, the following specific technical solutions are given for indication.

Scheme 1: Introduce a specific repetition indication signal to indicate the merging and merging formats of SS/PBCH blocks:

Step 1: The terminal detects the repetitive indication signal sent periodically;

Exemplarily, the repetition indication signal sequence is selected from a finite set of sequences, and each sequence, one or more of a sequence transmission position and a format corresponds to a combined format.

Step 2: the terminal identifies the sequence information of the repeat indication signal, and identifies the merge format corresponding to the sequence;

Step 3: The terminal combines and receives the PBCH according to the identified combining format.

Embodiment 1: Define a new repetition indication signal, the signal is selected from a set of sequences, and each sequence corresponds to a combined format.

Table 1: Correspondence of sequences to merged formats.

Embodiment 2: The combination of PSS and SSS in NR can indicate a total of 1008 cell IDs. In the mMTC scenario, the requirement for the number of cell IDs may be reduced, and the sequence corresponding to part of the Cell IDs can be reserved in the PSS and SSS to indicate the merging format of the SS/PBCH block.

Table 2: Correspondence of sequences to merged formats.

Embodiment 3: define a new repetition indication signal, the signal can be sent in different 5ms within 20ms, and the sent time position and sequence all carry the information of the combined format, as follows:

(1) When a new signal appears within a certain 5ms, it indicates that within the current 5ms, there are SS/PBCH blocks repeated;

(2) Use the sequence index to indicate the number of repetitions of the SS/PBCH block within the current 5ms, for example, use 4 sequences to indicate 1, 2, 4, and 8 repetitions;

(3) The pattern sent by the sequence, whether it is present in every 5ms or only once every 10ms, to indicate the transmission period of the SS/PBCH block;

(4) The time position/sequence index itself sent through the sequence indicates the number of 5ms; the terminal is prevented from doing multiple hypothesis merging.

Case 1: See Fig. 4, new signal appears in every 5ms → SS/PBCH block in every 5ms, which can be combined.

Case 2: Referring to Figure 5, the new signal appears once every 10ms → the SSB transmission period is 10ms, and can be combined within 10ms.

Further, a sequence may be sent on 2 symbols within each 5ms to indicate the sent 5ms position and the SS/PBCH block repetition within 5ms, exemplarily:

The sequence on the first symbol indicates the current 5ms within 20ms, and a maximum of 4 sequences are required,

The sequence on the second symbol represents the number of repetitions of the SS/PBCH block within the current 5ms, and a maximum of 4 sequences are required;

Further, 16 sequences can be used to indicate all the above information in a unified manner.

Further, on the basis of the above, a dimension may be added to indicate that the PBCH contents between 2, 4, and 2^N 80ms remain unchanged. For example, all information is indicated uniformly with 16×N sequences.

Scheme 2: A specific repetition indication channel is introduced, and the terminal searches for the channel to determine the maximum number of SS/PBCH blocks that can be combined, and/or the pattern (Pattern).

Step 1: the terminal detects the periodically sent repetitive channel synchronization signal and the repetitive indication channel;

The repeated channel synchronization signal is used for the terminal to perform initial synchronization, and the repeated channel Payload indicates the actual number of SS/PBCH blocks that can be combined, and/or Pattern;

The indicated combining format, for example, may be the format of N consecutive PBCHs within 80ms that can be combined, or the format of SSBs that can be combined within one 80m.

Step 2: the terminal identifies the sequence information of the repeat indication signal, and identifies the merge format corresponding to the sequence;

Step 3: The terminal combines and receives the PBCH according to the identified combining format.

Embodiment 3: The synchronization signal of the repetition channel may be an existing synchronization signal of NR, which has a fixed time-frequency resource relationship with the repetition indication channel; it may also be a newly defined synchronization signal. For example, the repeated channel has a fixed frequency offset from the SS/PBCH block.

See Table 3, which records the relationship between the repeat channel bearer content (Payload) and the indicated merge format.

See Table 4, which records the relationship between the repeat channel payload (Payload) and the indicated merge format.
