Method and apparatus for uplink control signaling

摘要

A system, a device and a method for allocating A/N resources are disclosed. In one embodiment the method comprises indicating an acknowledgement or negative acknowledgement (A/N) channel of a user equipment in a first cell, the A/N channel according to a first value and a second value, wherein the first value is determined by a physical layer parameter, wherein the second value is indicated by a high layer signaling, and wherein the A/N channel corresponds to a downlink transmission of a second cell.

主权项

1. A method for operating a user equipment, the method comprising:
receiving, by the user equipment, a downlink transmission from a transmit point, the downlink transmission carrying data and control information; determining, by the user equipment, a physical layer parameter associated with the control information; receiving, by the user equipment, a first higher layer signaling parameter; receiving, by the user equipment, a second higher layer signaling parameter, the second higher layer signaling parameter being a different parameter than the first higher layer signaling parameter; calculating, by the user equipment, an acknowledgement or negative acknowledgement (A/N) channel index by adding a resource offset to a starting control channel element specified by the physical layer parameter, wherein the resource offset has a first value specified by the first higher layer signaling parameter when the A/N channel index is calculated prior to receiving the second higher layer signaling parameter at the user equipment, and wherein the resource offset has a second value specified by the second higher layer signaling parameter when the A/N channel index is calculated after receiving the second higher layer signaling parameter at the user equipment, the second value being different than the first value; generating, by the user equipment, acknowledgment information relating to the data; and transmitting, by the user equipment, the acknowledgement information to a receive point using uplink resources associated with the A/N channel index.
