Definitions
- the present invention relates to the field of communications, and in particular, to a rate matching method and apparatus for downlink data.
- LTE Long Term Evolution
- the R11 version technology was studied again and again.
- some R8 versions are gradually commercialized, and the R9 and R10 versions are subject to further product planning.
- the R10 version adds many new features based on the former two, such as Demodulation Reference Signal (DMRS) and channel state information reference signal ( Channel State Information Reference Signal (CSI-RS) and other pilot characteristics, 8 antenna support and other transmission and feedback characteristics, especially Inter-Cell Interference Cancelling (elCIC) technology is considering R8 Based on the ICIC in the /9 version, the interference avoidance technique between cells is further considered.
- DMRS Demodulation Reference Signal

- elCIC Inter-Cell Interference Cancelling
- the cell interference avoidance under the isomorphic network is mainly considered in the early stage of the R10 version.
- the mainstream technology considers the elCIC technology and the coordinated multi-point (Coordinated Multi-point, referred to as CoMP) technology, CoMP means that multiple nodes cooperate to send data to one or more UEs on the same time-frequency resource or different time-frequency resources. Therefore, CoMP can reduce interference between cells and improve the throughput of cell edges. , expand cell coverage.
- LTE defines a physical downlink control channel (PDCCH) bearer scheduling allocation and other control information.
- PDCCH physical downlink control channel
- Each PDCCH is composed of a number of control channel elements (CCEs), and CCEs of each subframe. The number is determined by the number of PDCCHs and the downstream bandwidth.
- the user equipment User Equipment, referred to as UE
- the search space is divided into a common search space and a user-specific search space.
- the common search space refers to an area that all UEs search for.
- This space carries cell-specific information; the user-specific search space is a single
- the spatial range that the UE will search for, the user-specific search spaces of multiple UEs may overlap, but the general initial search location of the user-specific search space of each UE is different.
- the base station Before the UE performs blind detection, the base station generally informs the UE of the working mode to be adopted and the Cyclic Redundancy Check (CRC) scrambled wireless network temporary identifier ( Radio Network). Temporary Identity, referred to as RNTI) type.
- CRC Cyclic Redundancy Check
- RNTI Temporary Identity
- the UE When the UE performs blind detection in the user-specific search space, the UE first calculates the blind detection initial position according to the UE ID (user identification) and the subframe number, and then performs detection in the user-specific search space until the PDCCH assigned to itself is detected. until.
