Problems solved by technology

[0002] Existing communication protocols do not support resource mapping for DVRB (distributed VRB, distributed virtual resource block) under larger resource allocation and larger bandwidth configuration. Due to the introduction of larger bandwidth and CBG transmission in 5G, in In the case of large resource allocation, it is necessary to support DVRB mapping in this scenario

specific Embodiment 1

[0083]In this embodiment, the network side device sends the PRG configuration type to the user terminal, and the user terminal determines a DVRB mapping method (including interleaving granularity, interleaving The number of rows and / or the number of columns of a matrix (block interleaver), and the sending of the resource mapping configuration information to the user terminal includes:

[0084] Sending the configuration type of the PRG to the user terminal, so that the user terminal selects a resource mapping configuration mode from multiple resource mapping configuration modes according to the configuration type of the PRG, and the multiple resource mapping configuration modes are The pre-configured multiple resource mapping configurations or the multiple resource mapping configurations sent to the user terminal in advance, each resource mapping configuration includes the granularity of the interleaving and / or the number of rows of the interleaving matrix, and / or how to get t...

specific Embodiment 2

[0105] In this embodiment, the network side device sends the configuration type of the PRG to the user terminal, so that the user terminal determines the number of columns of the interleaving matrix according to the configuration type of the PRG.

[0106] In a specific implementation manner, the user terminal obtains the number of columns of the interleaving matrix under PRG type 1 according to RRC configuration or implicitly, and the protocol specifies the number of columns of the interleaving matrix under type 2;

[0107] For example: when the configuration of the PRG is type 1, that is, when the specific PRG size is notified according to the signaling (RRC or L1 signaling notification), the The group applies a block interleaver (block interleaver), and determines the number of columns of the block interleaver as:

[0108] (1): The number of columns of block interleaver is configured by RRC signaling That is, configured by the network side device to the user terminal thro...

specific Embodiment 3

[0118] In this embodiment, at the time of initial access, since no UE-specific signaling has been transmitted to the user terminal, special processing is required to determine which interleaving granularity and interleaving matrix to use specifically. Examples are as follows:

[0119] When initial access, the network side device sends fallback DCI (fallback DCI) to convey control signaling, consider using a fixed PRG type to simplify the process;

[0120] When the terminal receives RMSI (Remaining system information, remaining system information), message (message) 2 (RAR, random access response), message 4, OSI (Other system information, other system information) PDSCH (Physical Downlink Shared Channel, physical downlink Shared channel), and when the terminal uses DVRB to receive, consider using the following default methods for receiving:

[0121] (1): PRG type 1 is used by default, fixed PRG size, fixed interleaving granularity, and fixed number of interleaved columns, tha...

Abstract

The invention provides a resource mapping method, a determination method, network side equipment and a user terminal, belonging to the technical field of communication. Wherein, the resource mapping method is applied to the network side equipment, including: determining resource mapping configuration information of the physical downlink control channel, the resource mapping configuration information at least including the parameters of the block interleaver used in the resource mapping; according to the resource mapping The configuration information maps virtual resource blocks to physical resource blocks, and sends the resource mapping configuration information to the user terminal. The technical solution of the present invention can meet the resource mapping requirements of two different types of PRGs, type1 and type2.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a resource mapping method, a determination method, network side equipment and a user terminal. Background technique [0002] Existing communication protocols do not support resource mapping for DVRB (distributed VRB, distributed virtual resource block) under larger resource allocation and larger bandwidth configuration. Due to the introduction of larger bandwidth and CBG transmission in 5G, in In the case of large resource allocation, it is necessary to support DVRB mapping in this scenario. [0003] Under smaller resource allocation and larger bandwidth configuration, such as LTE (Long Term Evolution, Long Term Evolution) specifies more than 50 PRB (physical resource block, physical resource block), LTE supports a smaller scale, according to the cell bandwidth 1 / Mapping of DVRBs with a frequency spacing of the order of 4, the application of smaller frequency...
