Abstract
A method for indicating a structure of control information for a multimedia broadcast multicast service (MBMS) is provided. The method comprises separating a multicast control channel (MCCH) of an MBMS transmission into a first portion and a second portion and arranging the separated MCCH into either a first structure wherein the first portion includes at least one pointer to a location of the second structure, or a second structure wherein the first portion directly includes the second portion. The method further includes including in a downlink transmission an indicator to indicate which of the first structure and the second structure is used.
Claims20
A method comprising:
- separating by a network access equipment, a multicast control channel (MCCH) of a multimedia broadcast multicast service MBMS transmission into a first portion and a second portion and arranging the separated MCCH into one of:
- a first structure wherein the first portion includes at least one pointer to a location of the second portion, and
- a second structure wherein the first portion directly includes the second portion, and
- including in a downlink transmission an indicator to indicate which of the first structure and the second structure is used.
A user equipment, comprising:
- one or more processors configured to promote receiving a multicast control channel (MCCH) of a multimedia broadcast multicast service (MBMS) transmission, the MCCH comprising a first portion and a second portion, the first portion having either a first structure wherein the first portion includes at least one pointer to a location of the second portion or a second structure wherein the first portion directly includes the second portion, and wherein the one or more processors are further configured to receive an indicator that indicates which of the first structure and the second structure is used.
A network access equipment in a wireless telecommunications network for transmitting multimedia broadcast multicast service (MBMS) control information, comprising:
- one or more processors configured to promote transmission of a multicast control channel (MCCH) associated with a transmission of the MBMS, the MCCH comprising a first portion and a second portion, the first portion having either a first structure wherein the first portion includes at least one pointer to a location of the second portion or a second structure wherein the first portion directly includes the second portion, and wherein the one or more processors are configured to promote transmission of an indicator to indicate which of the first structure and the second structure is used.
