Abstract
The downlink shared channel includes dedicated physical channel control information for more than one mobile. In HSDPA, providing the downlink shared channel replaces the downlink dedicated physical channels for at least two mobiles.
Claims14
A method, comprising:
- providing a downlink shared channel shared by a plurality of mobiles and having a plurality of subframes, each subframe comprising a plurality of slots, each slot including a power control part composed of power control bits for the plurality of mobiles, a data status part and a data part;
- wherein the data status part is indicative of whether data in the data part is a beginning, middle or end of data for one of the plurality of mobiles.
A method, comprising:
- replacing at least two downlink dedicated physical channels with one downlink shared channel shared by a plurality of mobiles and having a plurality of subframes, each subframe comprising a plurality of slots, each slot including a power control part composed of power control bits for the plurality of mobiles, a data status part and a data part;
- wherein the data status part is indicative of whether data in the data part is a beginning, middle or end of data for one of the plurality of mobiles.
A method, comprising:
- multiplexing a downlink shared control shared by a plurality of mobiles and having a plurality of subframes, each subframe comprising a plurality of slots, each slot including a power control part composed of power control bits for the plurality of mobiles, a data status part and a data part;
- wherein the data status part is indicative of whether data in the data part is a beginning, middle or end of data for one of the plurality of mobiles.
A method for reducing use of channelization codes in a high speed data packet access communication system, comprising:
- providing a downlink shared control shared by a plurality of mobiles and a signaling channel having a plurality of subframes, each subframe comprising a plurality of slots, each slot including a power control part composed of power control bits for the plurality of mobiles, a data status part and a data part;
- wherein the data status part is indicative of whether data in the data part is a beginning, middle or end of data for one of the plurality of mobiles.
A method, comprising:
- transmitting a downlink shared channel shared by a plurality of mobiles and having a plurality of subframes, each subframe comprising a plurality of slots, each slot including a power control part composed of power control bits for the plurality of mobiles, a data status part and a data part;
- wherein the data status part is indicative of whether data in the data part is a beginning, middle or end of data for one of the plurality of mobiles.
A method, comprising:
- receiving, at a mobile station, at least a portion of a downlink shared channel shared by a plurality of mobiles and having a plurality of subframes, each subframe comprising a plurality of slots, each slot including a power control part composed of power control bits for the plurality of mobiles, a data status part and a data part;
- wherein the data status part is indicative of whether data in the data part is a beginning, middle or end of data for one of the plurality of mobiles.
