Description

Resource allocation method, device, system, storage medium and electronic device

This application claims the priority of the Chinese patent application filed with the Chinese Patent Office with application number 201910107366.1 on February 2, 2019. The entire content of this application is incorporated into this application by reference.

Technical field

This application relates to, but is not limited to, the field of communications, such as a resource configuration method, device, system, storage medium, and electronic device.

Background technique

In related technologies, the 2-step random access channel (Random Access Channel, RACH) can shorten the access method better than the 4-step RACH access method in the Long Term Evolution (LTE) system. The entry delay includes: the first step: the terminal (user equipment, UE) sends a message (message, msg) A to the base station, and the second step: the base station sends msg B to the terminal UE.

In some scenarios, 2-step RACH is not only to complete the task of accessing the network (such as obtaining uplink synchronization, or obtaining the unique identifier of the UE in the conflict resolution solution, that is, the Cell Radio Network Temporary Identifier, C- RNTI)), and can transmit a small amount of uplink data at the same time.

For example, a massive machine type of communication (Machine Type of Communication, mMTC) scenario, or an Enhanced Mobile Broadband (eMBB) small packet scenario, there may be a large number of terminals in the network, and the service of each terminal is occasional small packet data transmission. In other words, the terminal needs to complete the uplink transmission of small packet data in a scheduling-free (inactive) state. The 2-step RACH access method can meet this demand.

There is no solution to the problem of consuming signaling resources when indicating the resources used by the payload in the related art.

The description will be given below in conjunction with another embodiment of the present application.

In the related art, the msgA sent by the terminal to the base station mainly includes two parts: a preamble and a payload. For payload resources, such as time-frequency resources, or DMRS resources, if an indication is displayed, additional signaling resources need to be consumed. This application proposes a direct mapping method between preamble and payload resources (time-frequency resources, or DMRS resources), which can implicitly indicate the time-frequency resources and DMRS resources used by the payload according to the preamble index.

Another embodiment of this application includes the following examples.

Example one

64 preambles constitute a set, which is represented as set A.

A can be seen as consisting of 6 parts, represented by the set {A0 A1 A2 A3 A4 A5}, where Ai represents a subset of A, and the size of A0 A1 A2 A3 A4 A5 is (11,11,11,11,10 ,10), that is, A0 represents 11 preambles in A, A1 represents 11 preambles in A..., and similarly, A5 represents 10 preambles in A.

In an embodiment, the size of Ai or the number of preambles in Ai is n1 or n2. For example, n1=11, n2=10. A calculation method of n1, n2 is:

n1=ceil(64/6)+delt=11, (if delt=0);

n2=floor(64/6)+delt=10, (if delt=0);

The communication system configuration, the resource used by the payload sent with the preamble in Ai is PRBi.

Example two

Num_preamble preambles constitute a set, denoted as set A.

A can be regarded as composed of x_part parts, represented by the set {A0 A1 A2 A3 A4 Ax_part-1}, where Ai represents a subset of A,

In an embodiment, the size of Ai or the number of preambles in Ai is n1 or n2. A calculation method of n1, n2 is:

n1=ceil(Num_preamble/x_part)+delt;

n2=floor(Num_preamble/x_part)+delt;

When x_part is divisible by Num_preamble, n1=n2. delt=0,1,2 and other natural numbers.

The communication system configuration, the resource used by the payload sent with the preamble in Ai is PRBi.

or,

The communication system configuration, the resources used by the payload sent together with the preamble in Ai are PRB2i～PRB2i+1.

or,

In the communication system configuration, the resource used by the payload sent together with the preamble in Ai is the i-th block of RB, and one RB can be composed of one or more PRBs.

In an embodiment, the total bandwidth occupied by all payloads can be divided into x_part groups, where x-part is a natural number such as 2, 3, 4, 5, 6, 12, etc.

In an embodiment, the number of PRBs in a group belongs to the set {1, 2, 3, 4, 6, 8, 9}, or the number of PRBs in a group does not exceed 12 PRBs, or the number of PRBs in a group The number is a power of 2.

In an embodiment, the RBs of any two groups may be orthogonal in the frequency domain, may partially overlap, or may completely overlap.

In an embodiment, the broadcast signaling indicates the total bandwidth occupied by all payloads, that is, the time-frequency position offset relative to the PRACH resource of the physical random access channel.

Example three

When the demodulation reference signal adopts the new wireless NR Type2 pattern, there are 12 DMRS ports for 1 RB or 1 PRB.

On the basis of the communication system configuration of Example 1 or Example 2, the communication system configuration and the DMRS port resources used by the PUSCH sent together with the preamble in Ai are pi ports,

For example, in the communication system configuration, the DMRS port resources used by the PUSCH sent with the preamble in A0 A1 A2 A3 A4 A5 are p0 p1 p2 p3 p4 p5 ports respectively.

In an embodiment, the communication system configuration, the DMRS port resources used by the PUSCH sent together with the preamble in A0 A1 A2 A3 A4 A5 are 11, 11, 11, 11, 10, 10 ports, respectively.

In an embodiment, regarding the pi value, pi=n1 or n2. For example, n1=11, n2=10. A calculation method of n1, n2 is:

n1=ceil(Num_preamble/x_part)+delt;

n2=floor(Num_preamble/x_part)+delt;

In the above scheme, configuring the preamble sub-set corresponds to (11,11,11,11,10,10 ports) and has performance gains relative to (12,12,12,12,12,12 ports). The reason is to reduce The interference between the DMRS ports is reduced, especially the mutual interference between the two ports of the frequency domain orthogonal cover code (Orthogonal Cover Code, OCC). For example, the channel estimation performance of 12 DMRS ports multiplexing is worse than the channel estimation performance of 11 DMRS ports multiplexing. This difference will be more obvious when the time offset frequency offset is large.

Example four

When the DMRS adopts the NR Type1 pattern, there are 8 DMRS ports for 1 RB or 1 PRB. When the DMRS adopts the NR Type 2 pattern, there are 12 DMRS ports for 1 RB or 1 PRB. Assume that the DMRS port of 1 RB or 1 PRB has Num_port ports, Num_port=8 or 12 or others.

When the value n1 or n2 of the preamble in a set Ai is less than Num_port, the communication system configuration, the DMRS port used by the PUSCH sent with preamble_i1 and the DMRS port used by the PUSCH sent with preamble_i2 will not be the same in the same RB. A DMRS port.

The preamble_i1 or preamble_i2 are any two different preambles in the preamble set A.

When n1 or n2 is greater than Num_port, the communication system configuration, there are multiple preambles corresponding to the same DMRS port in the same RB, in other words, the communication system configuration, the DMRS port used by the PUSCH sent with preamble_i1 is sent with preamble_i2 The DMRS port used by the PUSCH is the same DMRS port in the same RB.

Example 5

According to the communication system configuration of Example 1 to Example 3, the transmitter UE randomly selects 1 preamble, and the UE sends the PUSCH on the RB corresponding to the preamble_index. And the DMRSport_indexth DMRS_port in the corresponding RB is used.

For example, Preamble_index=25, belonging to the third preamble subset (ceil(25/11)+delt=2 if delt=0).

DMRSport_index=(25-sum(p0,p1))%11=3, where p0 is 11 and p1 is 11.

That is, the UE transmits the PUSCH on the third RB, and uses the third DMRS_port in the third RB.

In an embodiment, the transmitted signal includes a payload, the number of ports occupied by the payload is a second value that is times i, and the second value is the value of the DMRS port in a physical resource block PRB in the DMRS pattern currently used for transmission The number, the i is an integer, and the i is less than the number of physical resource blocks. That is, when there is no preamble in the transmission signal and only the payload part, the payload part may or may not include DMRS. When DMRS is included, the corresponding relationship between PRB and DMRS port used by the payload is: the number of ports available for the payload is Num_DMRSport, or the number of ports available for the payload is Num_DMRSport*i; i<=the number of PRBs. Num_DMRSport is 8,12.

Example 6

It should be noted that the example 6 is the mapping relationship between the preamble and the payload resource when one UE occupies one RB. It includes the situation where one UE occupies one or more PRBs.

Table 1 is Table 1 of Example 6 according to another embodiment of the present application. As shown in Table 1, it shows a mapping of preamble index Preamble index, physical resource block index RB index, and demodulation reference signal index DMRS index Table, this table corresponds to the situation where the payload occupies 6RB.
