Abstract
There is provided a solution for transmitting a scheduling request on a physical uplink control channel (PUCCH) using multiple antennas with spatial transmit diversity, each antenna group including one or more antenna elements. There is also provided a solution for receiving control information on the physical uplink control channel separately from one or more resources, determining whether specific resources are occupied with control information, combining specific PUCCH resources and deciding on whether to schedule the transmitter of the control information for an uplink transmission or not.
Claims30
A method, comprising:
- recognizing an opportunity to transmit a scheduling request for an uplink transmission;
- and
- transmitting control information on a physical uplink control channel from multiple antenna groups with spatial transmit diversity, each antenna group comprising one or more antenna elements.
A method, comprising:
- receiving control information from one or more resources of a physical uplink control channel associated with a transmitter;
- determining whether specific resources of the physical uplink control channel are occupied with control information;
- combining the control information from the specific resources when the specific resources are occupied with control information;
- and
- deciding on whether to schedule the transmitter for an uplink transmission or not, when a resource for a scheduling request indicator is occupied with control information.
An apparatus, comprising:
- a processor configured to recognize an opportunity to transmit a scheduling request for an uplink transmission;
- and
- an interface configured to transmit control information on a physical uplink control channel from multiple antenna groups with spatial transmit diversity, each antenna group comprising one or more antenna elements.
An apparatus, comprising:
- an interface configured to receive control information from one or more resources of a physical uplink control channel associated with a transmitter;
- and a processor configured to:
- determine whether specific resources of the physical uplink control channel are occupied with control information;
- combine the control information on the specific resources when the specific resources are occupied with control information;
- and
- decide on whether to schedule the transmitter for an uplink transmission or not, when a resource for a scheduling request indicator is occupied with control information.
An apparatus, comprising:
- processing means for recognizing an opportunity to transmit a scheduling request for an uplink transmission;
- and
- means for transmitting control information on a physical uplink control channel from multiple antenna groups with spatial transmit diversity, each antenna group comprising one or more antenna elements.
An apparatus, comprising:
- means for receiving control information from one or more resources of a physical uplink control channel associated with a transmitter;
- processing means for determining whether specific resources of the physical uplink control channel are occupied with control information;
- processing means for combining the control information on the specific resources when the specific resources are occupied with control information;
- and
- processing means for deciding on whether to schedule the transmitter of the control information for an uplink transmission or not, when a resource for a scheduling request indicator is occupied with control information.
A computer program product, embodied on a computer-readable storage medium and comprising a program code which, when run on a processor, executes the method comprising:
- recognizing an opportunity to transmit a scheduling request for an uplink transmission;
- and
- controlling the transmission of control information on a physical uplink control channel from multiple antenna groups with spatial transmit diversity, each antenna group comprising one or more antenna elements.
