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

[0109] In specific embodiment 1, the DVRB mapping of one of the UEs is notified in a set of DVRB mapping modes (corresponding to different mapping bandwidths) through a protocol or through RRC (Radio Resource Control) signaling of a network-side device Mode, the sending the resource mapping configuration information to the user terminal includes:

[0110] The resource mapping configuration information is sent to the user terminal through RRC signaling, so that the user terminal selects a resource mapping configuration mode from a plurality of resource mapping configuration modes. It may also be the resource mapping configuration mode through RRC signaling. The number of the mapping configuration information is sent to the user terminal, so that the user terminal selects a resource mapping configuration mode from multiple resource mapping configuration modes, and the multiple resource mapping configuration modes are pre-configured multiple resource mapping configurations The metho...

specific Embodiment 2

[0113] In the second specific embodiment, the DVRB mapping mode (corresponding to different mapping bandwidths) of a group of UEs is configured through the protocol or through the RRC signaling of the network side device, and then a DVRB mapping mode is selected through L1 signaling. The resource mapping configuration information sent to the user terminal includes:

[0114] The resource mapping configuration information is sent to the user terminal through L1 signaling, so that the user terminal selects a resource mapping configuration mode from a plurality of resource mapping configuration modes. It may also be the resource mapping configuration method through L1 signaling. The number of the mapping configuration information is sent to the user terminal, so that the user terminal selects a resource mapping configuration mode from multiple resource mapping configuration modes, and the multiple resource mapping configuration modes are pre-configured multiple resource mapping config...

specific Embodiment 3

[0116] In specific embodiment three, the user terminal can implicitly determine a DVRB mapping method among a set of DVRB mapping methods (corresponding to different mapping bandwidths) according to the bandwidth of the actually scheduled resource. The bandwidth of the actually scheduled resource is the scheduled resource bandwidth. The bandwidth occupied by data is different from the transmission bandwidth and refers to how much bandwidth is actually used for scheduling. The sending of the resource mapping configuration information to the user terminal includes:

[0117] The number of scheduled resource blocks is notified to the user terminal, so that the user terminal selects a resource mapping configuration mode from a plurality of resource mapping configuration modes according to the number of scheduled resource blocks. The mapping configuration mode is a pre-configured multiple resource mapping configuration mode or a multiple resource mapping configuration mode sent to the u...

Abstract

The invention provides a resource mapping method, a determination method, network side equipment and a user terminal, and belongs to the technical field of communication. The resource mapping method is applied to network side equipment, and comprises the following steps: determining resource mapping configuration information of a physical downlink control channel; And mapping the virtual resourceblock to a physical resource block according to the resource mapping configuration information, and sending the resource mapping configuration information to a user terminal, so that the user terminalobtains the bandwidth occupied by resource dispersion mapping by using configuration parameters in the resource mapping configuration information. According to the technical scheme of the invention,resource mapping requirements of two different PRG types, namely type 1 and type 2, can be met.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a resource mapping method, a determination method, network side equipment and user terminals. Background technique [0002] The existing communication protocol does not support the resource mapping of DVRB (distributed VRB) under larger resource allocation and larger bandwidth configuration. Due to the introduction of larger bandwidth and CBG transmission in 5G, In the case of larger resource allocation, DVRB mapping needs to be supported in this scenario. [0003] With a smaller resource allocation and a larger bandwidth configuration, such as LTE (Long Term Evolution) stipulating 50PRB (physical resource block, physical resource block) or more, LTE supports a smaller scale, according to the cell bandwidth 1 / Mapping of DVRBs with a frequency interval of 4 orders of magnitude. The application of a smaller frequency interval allows the distributed transmission to be rest...
