Abstract
A base station may transmit downlink control information (DCI) scheduling communications between the base station and a UE. The DCI is in a fallback DCI format. Based on whether or not the DCI is in a UE specific search space with cyclic redundancy check (CRC) scrambled by a UE ID of the UE, data transmitted by the base station or by the UE according to the DCI may be scrambled by a sequence that is initialized with a configurable parameter, or initialized with a cell ID.
Claims30
A method, comprising:
- receiving, by a user equipment (UE), downlink control information (DCI) that schedules data communication for the UE;
- receiving, by the UE, data according to the DCI;
- and
- descrambling, by the UE, the data using a sequence that is initialized with a configurable parameter, upon detecting that the DCI is in a first format and the DCI is in a UE specific search space with cyclic redundancy check (CRC) scrambled by a UE identifier (UIEID) of the UE.
An apparatus, comprising:
- one or more processors, configured to couple with a non-transitory memory storage, wherein the non-transitory memory storage is configured to store instructions, which when executed, cause the one or more processors to:
- receive downlink control information (DCI) that schedules data communication for the apparatus or a UE which the apparatus is used for;
- receive data according to the DCI;
- and
- descramble the data using a sequence that is initialized with a configurable parameter, upon detecting that the DCI is in a first format and the DCI is in a UE specific search space with cyclic redundancy check (CRC) scrambled by a UE identifier (UE ID) of the apparatus or the UE which the apparatus is used for.
A non-transitory computer-readable media storing computer instructions, that when executed by one or more processors, cause the one or more processors to perform the steps of:
- receiving downlink control information (DCI) that schedules data communication for a user equipment (UE) which the non-transitory computer-readable media is used for;
- receiving data according to the DCI;
- and
- descrambling the data using a sequence that initialized with a configurable parameter upon detecting that the DCI is in a first format and the DCI is in a UE specific search space with cyclic redundancy check (CRC) scrambled by a UE identifier (UE ID) of the UE.
A system comprising:
- a base station;
- and
- a user equipment (UE), configured to communicate with the base station, wherein the UE includes one or more processors, configured to couple with a non-transitory memory storage, and wherein the non-transitory memory storage is configured to store instructions, which when executed, cause the one or more processors to:
- receive, from the base station, downlink control information (DCI) that schedules data communication for the UE;
- receive, from the base station, data according to the DCI;
- and
- descramble the data using a sequence that is initialized with a configurable parameter, upon detecting that the DCI is in a first format and the DCI is in a UE specific search space with cyclic redundancy check (CRC) scrambled by a UE identifier (UE ID) of the UE.
