Description

Wireless communication method and device

Technical Field

The present application relates to the field of communications technologies, and in particular, to a wireless communication method and device.

Background

In the 3GPP RAN1_ AH _1801 conference, the conference participants have negotiated a mapping relationship between a Synchronization Signal Block (SSB) and a random access timing (RACH occasion, RO) of a NEW 5G Radio technology (NEW Radio, NR) during random access.

Currently, a terminal device obtains parameters through system information: the number of SSBs (SSB-per-rach-event) mapped on each RO, the number of ROs multiplexed in the frequency domain at the same time (reach-FDM), and the number of SSBs actually transmitted, and the mapping relationship between the SSBs actually transmitted and the ROs is determined based on the three parameters.

However, when the prach-FDM is larger than 1, each SSB may be mapped to one or more ROs multiplexed in the frequency domain at the same time, i.e. there may be multiple SSB-RO mapping manners for the same prach-FDM and SSB-per-rach-event parameters. For example: fig. 1a to fig. 1c show that when the number of SSBs actually transmitted is 8(8SSBs), prach-FDM ═ 4, and SSB-per-rach-occase ═ 2(SSB _ per _ RO ═ 2), there are at least three mapping manners of SSBs and ROs. The uncertainty of the mapping manner will make the terminal device unable to determine the RO for detecting the SSB, i.e. unable to determine the random access resource corresponding to the SSB.

It should be understood that the technical solution of the embodiment of the present application may be applied to a 5G system, or a New Radio (NR) system.

For example, in an LTE network, referred to as an Evolved node B (eNB or eNodeB), in a third Generation (3rd Generation, 3G) network, referred to as a node B (node B), in a fifth Generation network, referred to as a gNB, and so on.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Example 1

Fig. 2 is a schematic flow chart of a wireless communication method according to embodiment 1 of the present invention, and referring to fig. 2, the method may specifically include the following steps:

step 22: the method comprises the steps that a network device sends indication information to a terminal device, wherein the indication information is used for the terminal device to determine random access opportunity (RACH occasion, RO) of a detection Synchronization Signal Block (SSB);

step 24: the terminal device determines the RO for detecting the SSB based on the instruction information from the network device.

It should be noted that, the first implementation manner of step 22 and step 24 may be:

the indication information is used to indicate the number of the ROs mapped with the same SSB (FDMed ROs with same SSB), which means the number of ROs mapped with the same SSB among all the ROs multiplexed in the frequency domain at the same time. Since the 3GPP RAN1_ AH _1801 conference indicates that the value of prach _ FDM may be {1,2,4,8}, the number of ROs mapped with the same SSB may be {1,2,3,4,5,6,7,8 }.

In the following, taking 8SSBs, prach _ FDM ═ 4, and SSB _ per _ RO ═ 2 as an example, the mapping manner of SSBs and ROs corresponding to different values of the number of ROs mapped with the same SSB is exemplarily described:

when the number of the frequency domain multiplexed ROs mapped with the same SSB is 1, the SSB and the ROs are mapped in the manner shown in fig. 3 a; when the number of the frequency domain multiplexed ROs mapped with the same SSB is 2, the SSB and the RO are mapped in the manner shown in fig. 3 b; when the number of frequency domain multiplexed ROs mapped with the same SSB is 4, SSB and RO are mapped in the manner of fig. 3 c.

Based on this indication information, referring to fig. 4, the step of the terminal device determining to detect the RO of the SSB may be:

step 42, determining the number of SSBs mapped on each RO and the number of ROs multiplexed in the frequency domain at the same time;

step 44, determining the number of the ROs mapped with the same SSB and indicated by the network device according to the indication information;

and step 46, determining the RO for detecting the SSB according to the number of the SSBs mapped on each RO, the number of the ROs multiplexed in the frequency domain at the same time and the number of the ROs mapped with the same SSB.

The manner in which the network device indicates three parameters, that is, the number of SSBs mapped on each RO, the number of ROs frequency-domain multiplexed at the same time, and the number of ROs mapped with the same SSB, to the terminal device may be:

the first two parameters, the number of SSBs mapped on each RO and the number of ROs multiplexed in the frequency domain at the same time, may be sent to the terminal device by the network device in the form of system information.

The third parameter, the number of ROs mapped with the same SSB, may be sent by the network device to the terminal device in a form that defines a new parameter (indication information), such as: at the time of initial access, sending Remaining Minimum System Information (RMSI) carrying indication Information to the terminal device, for example: system Information Block 1(System Information Block1, SIB 1); or after establishing Radio Resource Control (RRC) connection with the terminal device, sending an RRC message carrying the indication information to the terminal device. Wherein, different values of the number of ROs mapped with the same SSB can be represented by 2bits of information bits, which can be specifically referred to as the following table 1:

TABLE 1

Bit sequence	The number of ROs mapped with the same SSB
		00	1
01	2
		10	4
11	8

It is understood that the first implementation manner can define a new parameter by additionally adding 2bits of information bits without changing the mapping configuration of the existing SSB-to-RO, and indicate the number of ROs mapped by the terminal device with the same SSB, so that the terminal device can explicitly detect the ROs of the SSB.

A second implementation of steps 22 and 24 may be:

the indication information is used for indicating the number of the ROs multiplexed in the frequency domain at the same time and the number of the ROs mapped with the same SSB; that is, the SSB-to-RO mapping scheme is jointly indicated based on the existing parameters, i.e., the number of ROs multiplexed in the frequency domain at the same time. As in the first implementation, the selectable value of the number of ROs mapped with the same SSB is {1,2,3,4,5,6,7,8}, and this implementation takes the value of the number of ROs mapped with the same SSB as 1,2,4,8 as an example.

Based on this indication information, referring to fig. 5, the step of the terminal device determining to detect the RO of the SSB may be:

step 52, determining the number of SSBs mapped on each RO;

step 54, determining the number of the ROs multiplexed in the frequency domain at the same time and the number of the ROs mapped with the same SSB according to the indication information;

and step 56, determining the RO for detecting the SSB according to the number of the SSBs mapped on each RO, the number of the ROs multiplexed in the frequency domain at the same time and the number of the ROs mapped with the same SSB.

Wherein, the number of SSBs mapped on each RO, this parameter is sent by the network device to the terminal device in the form of system information, and the process is prior art and is not limited herein.

The number of the ROs multiplexed in the frequency domain at the same time and the number of the ROs mapped with the same SSB are sent to the terminal equipment by the network equipment in a form of defining a new parameter, and different values of the two parameters can be represented by 4bits of information bits. For example: when the prach-FDM is 2, the number of ROs mapped with the same SSB in frequency domain multiplexing may be 1 or 2, and the corresponding bit sequence may be 0001 or 0010; when the prach-FDM is 4, the number of ROs mapped with the same SSB in frequency domain multiplexing may be 1,2, and 4, and the corresponding bit sequence may be 0011, 0100, and 0101; when the prach-FDM is 8, the number of the frequency domain multiplexed ROs to which the same SSB is mapped may be 1,2,4, and 8, and the corresponding bit sequence may be 0110, 0111, 1000, and 1001. See table 2 below for details:

TABLE 2

It should be noted that the number of indicating bits used in this implementation is 4bits, which is the same as the number of bits used in the first implementation. 4bits can yield 16 sequence combinations, 10 of which are illustrated in Table 2. The remaining 6 are reserved sequences, and if more later needs to be indicated, these 6 sequences can be used.

In addition, it is understood that, in this implementation, the network device indicates, to the terminal device, the number of the ROs in the frequency domain multiplexing in which the same SSB is mapped and the value of the prach-FDM together, so that a situation that the value of the prach-FDM is greater than the number of the ROs in the frequency domain multiplexing in which the same SSB is mapped and the terminal device needs additional processing operations caused by the foregoing situation can be avoided, for example: a downward configuration processing operation in a first implementation; or, affect the efficiency of wireless communication, such as: when the values of the 8SSBs and the prach-FDM are 8 and the number of the frequency domain multiplexed ROs mapped with the same SSB is 4, the terminal device needs to complete the transmission of the 8SSBs through the frequency domain multiplexed ROs at two times.

A third implementation of steps 22 and 24 may be:

the indication information is used for indicating the number of SSBs mapped on each RO, the number of ROs frequency domain multiplexed at the same time and the number of ROs mapped with the same SSB; wherein the number of SSBs mapped on each RO is greater than or equal to 1. That is, the SSB-to-RO mapping manner is jointly indicated based on the existing parameters, i.e., the number of ROs frequency-domain multiplexed at the same time and the number of SSBs mapped on each RO.

Based on this indication information, referring to fig. 6, the step of the terminal device determining to detect the RO of the SSB may be:

step 62, determining the number of SSBs mapped on each RO, the number of ROs frequency domain multiplexed at the same time and the number of ROs mapped with the same SSB according to the indication information;

and step 64, determining the RO for detecting the SSB according to the number of the SSBs mapped on each RO, the number of the ROs multiplexed in the frequency domain at the same time and the number of the ROs mapped with the same SSB.

It is understood that, when the number of SSBs mapped on each RO is greater than or equal to 1, there are 5 values {1,2,4,8,16}, each value may correspond to 4 prach-FDM of {1,2,4,8} and a corresponding value of the number of ROs mapped with the same SSB (as in the first implementation, the number of ROs mapped with the same SSB is optionally {1,2,3,4,5,6,7,8}, and in the present implementation, the number of ROs mapped with the same SSB is 1,2,4, 8), that is, there are 50 combinations, specifically see table 3 below:

TABLE 3

It can be seen that the present implementation uses the 6-bits indication in common, and compared with the 3-bits (SSB-per-rach-event) + 2-bits (reach-FDM) + 2-bits (number of FDMed ROs with same SSB) required by the first implementation, the present implementation has the advantage of saving 1-bit overhead.

Regarding the three implementation manners, an embodiment of the present invention further provides an optimization scheme, which may include:

judging the number of the RO multiplexed in the frequency domain at the same moment and the number of the RO mapped with the same SSB;

if the number of the ROs multiplexed in the frequency domain at the same time is smaller than the number of the ROs mapped with the same SSB, for example, the number of the ROs mapped with the same SSB indicated by the indication information is 8, and the number of the ROs multiplexed in the frequency domain at the same time configured or indicated for the terminal device by the network device is 4, the terminal device needs to perform the reconfiguration reducing process, which may specifically include:

reducing the number of indicated ROs mapped with the same SSB to 4 or less than 4, and performing a subsequent step of determining the ROs for detecting the SSB based on the reduced value, that is, determining the ROs for detecting the SSB according to the target number (reduced value), the number of SSBs mapped on each RO, and the number of ROs multiplexed in the frequency domain at the same time;

and mapping the same SSB on the target number of ROs, wherein the target number is less than or equal to the number of ROs multiplexed in the frequency domain at the same time.

If the number of ROs frequency-domain multiplexed at the same time is greater than or equal to the number of ROs mapped with the same SSB, for example, the number of ROs mapped with the same SSB indicated by the indication information is 2, and the number of ROs frequency-domain multiplexed at the same time configured or indicated by the network device for the terminal device is 4, the reconfiguration process need not be performed.

In addition, a fourth implementation manner of step 22 and step 24 may be:

the indication information is used for indicating the number of SSBs mapped on each RO and the number of ROs frequency domain multiplexed at the same time; wherein the number of SSBs mapped on each RO is less than 1. When the SSB-per-rach-occasion is less than 1, there are 3 values for SSB-per-rach-occasion less than 1 and 4 values for prach-FDM, because there is no need to indicate the number of ROs mapped with the same SSB for frequency domain multiplexing, and thus there are 12 combinations in total. The network device can realize the purpose of indicating the SSB and RO mapping modes by configuring a unique corresponding bit sequence for each combination and carrying the bit sequence in the indication information.

Based on this indication information, referring to fig. 7, the step of the terminal device determining to detect the RO of the SSB may be:

step 72, determining the number of SSBs mapped on each RO and the number of ROs frequency domain multiplexed at the same time according to the indication information;

and step 74, determining the RO for detecting the SSB according to the number of the SSB mapped on each RO and the number of the ROs multiplexed in the frequency domain at the same time.

The combination of the bit sequence optionally carried by the indication information and the number of SSBs mapped on each RO corresponding to the bit sequence and the number of ROs multiplexed in the frequency domain at the same time can be seen in table 4 below:

TABLE 4

In summary of the four implementation manners, in this embodiment, the indication information is sent to the terminal device, so that the terminal device explicitly detects the RO of the SSB based on the indication information, thereby avoiding a problem that the terminal device cannot determine the RO of the SSB, that is, cannot determine the random access resource corresponding to the SSB, due to the existence of multiple SSB and RO mapping manners, and thus improving reliability of wireless communication.

For simplicity of explanation, the above-described method embodiments are described as a series of acts or combinations, but those skilled in the art will appreciate that the present invention is not limited by the order of acts, as some steps may occur in other orders or concurrently with other steps in accordance with the embodiments of the present invention. Furthermore, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
