Abstract
Method, apparatus and computer program product are disclosed for transmission in a wireless network. A method comprises: transmitting an uplink data block using grant free; detecting a downlink channel after a predefined timing or in a predefined time window; and determining whether the downlink channel being for a user equipment, wherein the uplink data block comprises information for identifying the user equipment identity, and a part of the user equipment identity is used to scramble a predefined part of the user equipment specific downlink channel.
Claims18
A method comprising:
- transmitting an uplink data block using grant free transmission;
- detecting a downlink channel after a predefined timing or in a predefined time window;
- and
- determining whether the downlink channel is for a user equipment,
- wherein the uplink data block comprises information for identifying the user equipment identity, and a part of the user equipment identity is used to scramble a predefined part of the user equipment specific downlink channel, and
- wherein the part of the user equipment identity is least significant bits or most significant bits of the user equipment identity.
An apparatus comprising:
- at least one processor;
- and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to
- transmit an uplink data block using grant free transmission;
- detect a downlink channel after a predefined timing or in a predefined time window;
- and
- determine whether the downlink channel is for a user equipment,
- wherein the uplink data block comprises information for identifying the user equipment identity, and a part of the user equipment identity is used to scramble a predefined part of the user equipment specific downlink channel, and
- wherein the part of the user equipment identity is least significant bits or most significant bits of the user equipment identity.
An apparatus comprising:
- at least one processor;
- and
- at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to
- receive an uplink data block transmitted by a user equipment using grant free transmission,
- wherein the uplink data block comprises information for identifying the user equipment identity;
- recognize the user equipment based on the information;
- and
- transmit a downlink channel to the user equipment after a predefined timing or in a predefined time window,
- wherein a part of the user equipment identity is used to scramble a predefined part of the user equipment specific downlink channel, and
- wherein the part of the user equipment identity is least significant bits or most significant bits of the user equipment identity.
