  • Publication number: 20220255712
    Abstract: Short Control Channel Elements (SCCE) to Short Resource Element Groups (SREG) mapping for Short Physical Downlink Control Channel (SPDCCH) is provided. A User Equipment (UE) receives a communication from a base station; determines a mapping between one or more SCCE and corresponding SREG; and processes the communication based on the mapping. A base station determines a mapping between one or more SCCE and corresponding SREG for a communication to a UE and transmits a communication to the UE based on the mapping. In this way, the localized and distributed SCCE to SREG mapping for CRS-based SPDCCH is defined. Also, the SCCE to SREG mapping for 2 and 3 OFDM symbols DMRS-based SPDCCH is defined. For DMRS-based SPDCCH, a distributed configuration at SCCE level is defined. This may improve latency and can improve the average throughput of a communications system. Radio resource efficiency could be positively impacted by latency reductions.

This switching may be triggered by occurrence of an event. During a second portion (2 OB) of the active time (20) occurring subsequent to the first portion (20A) and after this switching, then, the wireless device (14) monitors the control channel (18) using the second control channel monitoring configuration (22-N). The first portion (20A) of the active time (20) and the second portion (2 OB) of the active time (20) may be included in the same DRX cycle.
