Uplink control and data transmission in a mixed single and multiple carrier network

摘要

Providing for mixed single carrier and multi-carrier uplink transmission in a wireless communication environment is described herein. By way of example, a network is provided that can identify uplink capabilities or restrictions of respective devices of a mixed population of mobile devices, and schedule single carrier or multi-carrier transmissions accordingly. In some aspects, different subsets of multi-carrier transmission can be given priority over other subsets. Based on the priority, the network can schedule/modify relative transmit powers for respective subsets, accommodate power constraints of higher level networking protocols, and optionally give priority to one or more of the distinct transmissions. In addition, priority can be given to respective subsets of the multi-carrier transmission, to ensure high quality or reliability for important transmissions. Thus, provided is an integrated network that accommodates a powerful mix of single carrier and multi-carrier services for a mixed population of mobile devices.

1. A method of wireless communication involving a third generation partnership project long term evolution advanced (a 3GPP LTE-A) wireless system, comprising:
configuring, by a base station, physical uplink control channel (PUCCH) resources of a wireless subframe for transmission of control information; scheduling, by the base station, physical uplink shared channel (PUSCH) resources of the wireless subframe for transmission of data information; scheduling, by the base station, a first subset of a population of mobile devices to transmit data information on PUSCH resources for a wireless subframe, wherein the first subset also concurrently transmits control information on the PUCCH resources for the wireless subframe; scheduling, by the base station, a second subset of the population of mobile devices to transmit data information only on the PUSCH resources for the wireless subframe, wherein the second subset also transmits control information on the PUSCH resources for the wireless subframe; establishing a priority for a subset of multi-carrier traffic transmitted by a mobile device, wherein the priority establishes a target transmit power for a control portion of the multi-carrier traffic if the mobile device is constrained to a maximum transmit power, and further wherein the priority implies that data traffic is to be transmitted at a power that does not exceed a difference of the maximum transmit power and the target transmit power; and identifying an UL transmit power constraint pertaining to the first subset of the population of mobile devices, wherein the UL transmit power constraint comprises a data transmit power value and a control transmit power value different from said data transmit power value.
