Abstract:
In one embodiment, a message is sent (S310) from the wireless network ( 10) to a user equipment (20) having a variable rate vocoder (22). The message defines transport block sizes for the user equipment to select from in making uplink transmissions if the user equipment is permitted to vary a packet size for uplink transmission. A scheduling grant is sent (S320) to the user equipment, and the scheduling grant includes an indicator indicating that the user equipment is permitted to vary the packet size for uplink transmissions by selecting a transport block size from among the defined transport block sizes.
Abstract:
To address the need for new interference cancellation techniques that are able to deliver adequate performance but with reduced processing requirements, various embodiments are described. In some embodiments, a receiving device demodulates and decodes (201) at least one first-group user from a multi-user input signal. This multi-user input signal includes at least one first-group user and at least one second-group user, the first-group users having a shorter transmission time interval (TTI) than the second-group users. The receiving device reconstructs 202) an interference signal for each of the first-group users that were successfully decoded and subtracts (203) each interference signal from the multi-user input signal to generate an interference-canceled signal. The receiving device then demodulates and decodes (204) at least one second-group user using this interference-canceled signal.
