MOBILITY-BASED RADIO RESOURCE ASSIGNMENT METHODS, SYSTEMS AND DEVICES

摘要

Mobility-based radio resource assignment methods, systems and devices can assign user equipment to different nonoverlapping groups of radio resources depending on mobility of the user equipment. The groups of radio resources are nonoverlapping in time, frequency and/or code. For example, the groups of radio resources can include different pilot symbol densities, link adaptation and/or scheduling algorithms. The radio resources may be Long Term Evolution (LTE) radio resources.

主权项

1. 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 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.
