  • Publication number: 20100110878
    Abstract: An approach is provided for an efficient control signaling associated with an error control scheme. A determination is made whether data has been properly received according to an error control scheme. A first pilot sequence representing an acknowledgement is generated if the data is properly received. A second pilot sequence representing a negative acknowledgement is generated if the data is not properly received. A frame including either the first pilot sequence or the second pilot sequence is output.

  • Patent number: 7653140
    Abstract: A solution for radio access in a code division multiple access (CDMA)-based telecommunication system, in which orthogonal spreading codes are used for separating data of a plurality of user entities, is provided. According to the solution, a different pilot symbol sequence is allocated to each user entity, and the pilot symbol sequences of user entities are selected by allocating different frequencies for pilot symbol sequences of different user entities according to a frequency division multiple access (FDMA) technique in order to mitigate the effect of multiple access interference.

  • Publication number: 20090303978
    Abstract: A symbol multiplied by a first constant amplitude zero autocorrelation code CAZAC reference signal RS is transmitted in a timeslot from a first antenna of a user equipment on a first physical uplink control channel in a manner that multiplexes with other user equipments. A symbol multiplied by a second CAZAC RS is transmitted in the timeslot from a second antenna of the user equipment on a second physical uplink control channel in a manner that multiplexes with other user equipments. The first and second CAZAC RSs are orthogonal to one another by at least one of the cyclic shifts or a cover code applied to at least one of the first and the second CAZAC RSs. The symbols may be the same or different, and may represent an ACK, a NACK, or a scheduling request indicator. These teachings extend to more than two transmit antennas.

  • Publication number: 20090219897
    Abstract: A method for signaling between a mobile apparatus (10) and a network node (12) is described. The method includes generating a message that includes a scheduling request. Determining whether a second indication (e.g., an acknowledgment) is to be transmitted in a sub-frame with the first indication is also included. The method includes, in response to a determination that the second indication is not to be included, the message is configured in a first configuration and, in response to a determination that the second indication is to be included, the message also includes the second indication and the message is configured in a second configuration. The first configuration is distinct from the second configuration. The method also includes sending the message, via a wireless transmitter, in the sub-frame.
