摘要： Methods, devices, and systems for the transmission of information in a wireless communication system are disclosed. In one embodiment, a method for the transmission of information in a wireless communication system comprises receiving a downlink message, wherein the downlink message includes a first control channel element; determining a first index using the location of the first control channel element; determining a second index; determining a first orthogonal resource using the first index; determining a second orthogonal resource using the second index; spreading an uplink message using the first orthogonal resource to form a first spread signal; spreading the uplink message using a second orthogonal resource to form a second spread signal; transmitting the first spread signal using a first antenna; and transmitting the second spread signal using a second antenna.

摘要： A method and system for access and uplink power control for a wireless system having multiple transmit points. In one aspect a method operating in a wireless network having a plurality of transmission points (TP) including a macro evolved Node B (eNB) and at least one low power node (LPN) having transmit power lower than that of the macro eNB, the method detecting, by the user equipment, a transmission point having a lowest path loss to the user equipment; and transmitting, by the user equipment, a physical random access channel (PRACH) preamble on a PRACH directed to the transmission points having the lowest path losses.

摘要： A method for indicating a precoding granularity value. The method includes an access node performing at least one of dynamically signaling the precoding granularity value in downlink control information, semi-statically signaling the precoding granularity value through high-layer signaling, and implicitly signaling the precoding granularity value through a link with at least one parameter that the access node transmits for another purpose.
