Abstract
A service providing apparatus, a service consuming apparatus, and a service transmitting method thereof are provided. The service providing apparatus is able to pre-allocate a plurality of service consuming apparatus into different groups, to pre-schedule the groups in a control channel, and to pre-schedule the groups in at least one channel. Accordingly, the channel resource can be consumed more efficiently by the service consuming apparatus.
Claims28
A service transmitting method for a service providing apparatus, the service providing apparatus being adapted to connect to a plurality of service consuming apparatuses via a wireless network, the service transmitting method comprising the steps of:
- (a) enabling the service providing apparatus to determine a control period schedule of a first coordination set and a second coordination set in a control channel, and determine a service period schedule of a first service apparatus group and a second service apparatus group in at least one service channel, wherein the first coordination set at least comprises the first service apparatus group, and the second coordination set at least comprises the second service apparatus group;
- (b) enabling the service providing apparatus to transmit a broadcast message, which comprises the control period schedule and the service period schedule, to the service consuming apparatuses, wherein the broadcast message is configured to notify the service consuming apparatuses of being allocated into the first service apparatus group and the second service apparatus group respectively, to notify the service consuming apparatuses allocated into the first service apparatus group of being included in the first coordination set, and to notify the service consuming apparatuses allocated into the second service apparatus group of being included in the second coordination set;
- (c) enabling the service providing apparatus to, according to the control period schedule, receive an access request from the first service apparatus group included in the first coordination set in a first control period of the control channel, and to receive an access request from the second service apparatus group included in the second coordination set in a second control period of the control channel;
- and
- (d) enabling the service providing apparatus to provide, in the at least one service channel, a first service resource to the first service apparatus group in a first service period and to provide a second service resource to the second service apparatus group in a second service period according to the service period schedule.
