  • SHORT CONTROL CHANNEL ELEMENT (SCCE) TO SHORT RESOURCE ELEMENT GROUPS (SREG) MAPPING FOR SHORT PHYSICAL DOWNLINK CONTROL CHANNEL (SPDCCH)
    Publication number: 20200274681
    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.

The method may comprise, when operating with a short Transmission Time Interval (sTTI), and when using connected mode discontinuous reception, DRX, monitoring transmissions from a radio access network node during a first part of a subframe for a UE-specific message for the UE containing first control information. If no UE-specific message for the UE containing first control information is received, the UE may be inactive during a second part of the subframe following after the first part of the subframe. If the UE receives the UE-specific message containing first control information, it may monitor the second part of the subframe for a message containing second control information, for use in receiving or transmitting data from or to the radio access network node.

  • Method and apparatus for separate scheduling of uplink data and reference signal transmissions in a communication network
    Patent number: 10659205
    Abstract: According to one aspect of the teachings herein, a base station (20) schedules the transmission of uplink reference signals by a wireless device (16) separately from scheduling uplink data transmissions by the device (16). The separate scheduling may be done at specific times, under specific conditions, and with respect to specific devices (16) or groups of devices (16). Separate scheduling allows, for example, the base station (20) to use smaller scheduling intervals that are possible when uplink reference signals are integrally included in any scheduled uplink data transmission. As a further advantage, the density or number of uplink reference signal transmissions by a given device (16) can be adapted, e.g., based on channel conditions, data transmission formats, etc.
