Patent ID: 8861448

Claim:
A method of assigning radio resources for wireless communication with user equipment, comprising: assigning the user equipment to one of a first group of radio resources that does not provide coordinated multipoint (CoMP) transmission or to a second group of radio resources that is nonoverlapping with the first group and that provides CoMP transmission, depending on mobility of the user equipment, wherein the second group of radio resources provides coherent CoMP transmission to transmit signals to a first one of the user equipment that is in or near a channel matrix nullspace of a second one of the user equipment, wherein the channel matrix nullspace includes little or no interference from the second one of the user equipment, wherein the radio resources are Long Term Evolution (LTE) radio resources, wherein the first group of radio resources comprises a first group of carriers having a first Reference Signal (RS) pattern per antenna and wherein the second group of radio resources comprises a second group of carriers that is different than the first group and having a second RS pattern per antenna that is sparser than the first RS pattern, and wherein assigning the user equipment to one of a first group of radio resources or to a second group of radio resources depending on the mobility of the user equipment comprises assigning the user equipment to the first group if the user equipment is mobile and assigning the user equipment to the second group if the user equipment is stationary.
