CONTROL CHANNEL RESOURCE TRANSMISSION METHOD, BASE STATION AND USER EQUIPMENT
First Claim
1. A control channel resource transmission method, comprising:
- mapping more than one enhanced control channel element (E-CCE) onto a resource set, wherein each E-CCE is mapped onto a corresponding first resource subset and a corresponding second resource subset respectively, the first resource subset occupies a first time domain symbol set in a time domain and occupies a first preset frequency domain subcarrier set in a frequency domain, and the second resource subset occupies a second time domain symbol set in a time domain and occupies a second preset frequency domain subcarrier set in a frequency domain, so that each E-CCE occupies a resource of the same size or a difference between sizes of resources occupied by the E-CCEs is less than a preset threshold, wherein the E-CCEs are carried on the resource set for transmission; and
transmitting the resource set that carries the E-CCEs to a user equipment.

Abstract
Embodiments of the present invention provide a control channel resource transmission method, a base station and a user equipment which can ensure balance between performance of E-CCEs on a resource set, and further ensure scheduling and receiving performance of the E-CCEs. A control channel resource transmission method includes: mapping, by a base station, more than one enhanced control channel element E-CCE onto a resource set, where each E-CCE is mapped onto a corresponding first resource subset and a corresponding second resource subset respectively, so that each E-CCE occupies a resource of the same size or a difference between sizes of resources occupied by the E-CCEs is less than a preset threshold, where the E-CCEs are carried on the resource set for transmission; and transmitting the resource set that carries the E-CCEs to a user equipment; and demodulating, by the user equipment, the resource set and performing receiving.

6. A control channel resource transmission method, comprising:
-
demodulating more than one enhanced control channel element (E-CCE) mapped onto a resource set, wherein the E-CCEs are demodulated on a first resource subset and a second resource subset corresponding to each E-CCE separately, the first resource subset occupies a first time domain symbol set in a time domain and occupies a first preset frequency domain subcarrier set in a frequency domain, and the second resource subset occupies a second time domain symbol set in a time domain and occupies a second preset frequency domain subcarrier set in a frequency domain, so that each E-CCE occupies a resource of the same size or a difference between sizes of resources occupied by the E-CCEs is less than a preset threshold, wherein the E-CCEs are carried on the resource set for transmission; and receiving, according to the demodulated E-CCEs, the resource set that carries the E-CCEs and is transmitted by a base station. - View Dependent Claims (7, 8, 9, 10)
