Abstract
Systems, methods, apparatuses, and computer program products for time division duplex (TDD) uplink/downlink (UL/DL) configuration indication for TDD interference management and traffic adaptation (eIMTA) are provided. One method includes providing, by a network node, a time division duplex (TDD) uplink/downlink (UL/DL) configuration indication pattern. The TDD UL/DL configuration indication pattern may be used to indicate multiple TDD UL/DL configurations in DCI format C associated with the certain configured carriers and the concrete fixed downlink subframe index.

A method, comprising:
- configuring, by a network node, a time division duplex (TDD) uplink/downlink (UL/DL) configuration indication pattern that is used to indicate multiple TDD UL/DL configurations in DCI format 1C;
- and
- providing, to at least one user equipment, the TDD UL/DL configuration indication pattern to indicate the multiple TDD UL/DL configurations in DCI format 1C, wherein each of the TDD UL/DL configurations is associated with certain configured carriers and a concrete fixed downlink subframe index,
- wherein the providing further comprising providing the configuration indication pattern comprising a mapping relationship between the TDD UL/DL configurations in one DCI format 1C in one fixed downlink subframe and the carrier index.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to
- configure a time division duplex (TDD) uplink/downlink (UL/DL) configuration indication pattern that is used to indicate multiple TDD UL/DL configurations in DCI format 1C;
- provide, to at least one user equipment, the TDD UL/DL configuration indication pattern to indicate the multiple TDD UL/DL configurations in DCI format 1C, wherein each of the TDD UL/DL configurations is associated with certain configured carriers and a concrete fixed downlink subframe index,
- wherein the configuration indication pattern comprises a mapping relationship between the TDD UL/DL configurations in one DCI format 1C in one fixed downlink subframe and the carrier index.
A non-transitory computer readable memory embodying at least one computer program code, the at least one computer program code executable by at least one processor to perform a method comprising:
- receiving a time division duplex (TDD) uplink/downlink (UL/DL) configuration indication pattern for indicating multiple TDD UL/DL configurations in DCI format 1C, wherein each of the TDD UL/DL configurations is associated with certain configured carriers and a concrete fixed downlink subframe index,
- wherein the receiving comprises receiving the configuration indication pattern comprising a mapping relationship between the TDD UL/DL configurations in one DCI format 1C in one fixed downlink subframe and the carrier index.
A method, comprising:
- receiving, by a network node, a time division duplex (TDD) uplink/downlink (UL/DL) configuration indication pattern for indicating multiple TDD UL/DL configurations in downlink control information (DCI) format 1C, wherein each of the TDD UL/DL configurations is associated with certain configured carriers and a concrete fixed downlink subframe index,
- wherein the receiving comprises receiving the configuration indication pattern comprising a mapping relationship between the TDD UL/DL configurations in one DCI format 1C in one fixed downlink subframe and the carrier index.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- the at least one memory and computer program code configured, with the at least one processor, to cause the apparatus at least to
- receive a time division duplex (TDD) uplink/downlink (UL/DL) configuration indication pattern for indicating multiple TDD UL/DL configurations in downlink control information (DCI) format 1C, wherein each of the TDD UL/DL configurations is associated with certain configured carriers and a concrete fixed downlink subframe index,
- wherein the configuration indication pattern comprises a mapping relationship between the TDD UL/DL configurations in one DCI format 1C in one fixed downlink subframe and the carrier index.
