Managing a radio transmission between a base station and a user equipment

摘要

It is described a method for managing a radio transmission between a base station and a user equipment, wherein a communication channel is used for the radio transmission, wherein the communication channel includes a plurality of channel resources and is based on a MIMO transmission scheme. The method includes dividing the plurality of channel resources into a set of channel resource regions, assigning a MIMO rank to each channel resource region, wherein the MIMO rank is indicative for a number of channel resources to be used for a radio transmission within a corresponding channel resource region, selecting a channel resource region for the radio transmission between the base station and the user equipment, and managing the radio transmission between the base station and the user equipment based on the selected channel resource region and the corresponding assigned MIMO rank.

1. A method for managing a radio transmission in a cellular network between a base station and a user equipment, wherein a communication channel is used for the radio transmission, wherein the communication channel comprises a plurality of channel resources and is based on a multiple input multiple output transmission scheme, the method comprising
dividing the plurality of channel resources into a set of channel resource regions based on a frequency and/or time domain pattern, assigning a multiple input multiple output rank to each channel resource region, wherein the multiple input multiple output rank is indicative for a number of channel resources to be used for a radio transmission within a corresponding channel resource region, selecting a channel resource region for the radio transmission between the base station and the user equipment, and managing the radio transmission between the base station and the user equipment based on the selected channel resource region and the corresponding assigned multiple input multiple output rank, wherein the base station uses the same frequency and/or time domain pattern as a neighboring base station such that a given channel resource region is assigned the same multiple input multiple output rank by the base station as the neighboring base station based on the same frequency and/or time domain pattern.
