Base station, user equipment, and communication signal transmitting and receiving methods

A communication signal transmitting method, comprising:

• determining at least two different resource element groups to use to transmit a broadcast channel, each different resource element group of the at least two different resource element groups to be used to separately transmit the broadcast channel;
• and
• transmitting the broadcast channel to user equipment on the at least two different resource element groups, wherein for each resource element group the broadcast channel transmitted on the respective resource element group carries at least one piece of same information and indication information indicating a resource of a physical downlink control channel (PDCCH) used by the user equipment, and the same information is cell specific information.

A communication signal receiving method, comprising:

• determining, from at least two different resource element groups, at least one resource element group to use to receive a broadcast channel, wherein the broadcast channel is transmitted using the at least two different resource element groups, each different resource element group of the at least two different resource element groups is used to separately transmit the broadcast channel, and wherein, for each resource element group, the broadcast channel transmitted on the respective resource element group carries at least one piece of same information and indication information indicating a resource of a physical downlink control channel (PDCCH) used by a user equipment, and the same information is cell specific information;
• and
• receiving the broadcast channel based on the at least one resource element group, and obtaining, from the received broadcast channel, the indication information carried in the received broadcast channel.
