Short-term control channel element (SCCE) to short-term resource element group (SREG) mapping for short-term physical downlink control channel (SPDCCH)
Short-term control channel element (SCCE) to short-term resource element group (SREG) mapping for short-term physical downlink control channel (SPDCCH)
Short-term control channel element (SCCE) to short-term resource element group (SREG) mapping for a short-term physical downlink control channel (SPDCCH) is provided. A user equipment (UE) receives communication from a base station; Determine a mapping between one or more SCCEs and corresponding SREGs; It also handles communication based on the mapping. The base station determines the mapping between one or more SCCEs and corresponding SREGs for communication to the UE and transmits communication to the UE based on the mapping. In this way, local and distributed SCCE to SREG mapping is defined for CRS-based SPDCCH. In addition, SCCE to SREG mapping is defined for 2 and 3 OFDM symbols DMRS-based SPDCCH. For DMRS-based SPDCCH, a distributed configuration at the SCCE level is defined. This can improve latency and improve the average throughput of the communication system. Radio resource efficiency can be positively affected by reduced latency.
