Abstract
Described is a system having a mobile station and an access point which connects the mobile station to a network. The mobile station has a first mode of operation and a second mode of operation. In the first mode of operation, the mobile station transmits a data packet intended for a further mobile station to the access point and the access point transmits the data packet to the further mobile station. In the second mode of operation, the mobile station transmits the data packet intended for the further mobile station directly to the further mobile station.
Claims20
A mobile station, comprising:
- a processor;
- and
- a memory containing a table and storing a set of instructions for execution on the processor;
- wherein the set of instructions, when executed, causes the mobile station to:
- listen for one of a transmission of a data packet by an access point to a further mobile station and a transmission of an acknowledgment by the further mobile station to the access point;
- add an address of the further mobile station to the table when the one of the listened for transmissions is detected;
- and
- send a further data packet destined for the further mobile station directly to the further mobile station when the address is present in the table.
A mobile station, comprising:
- a processor;
- and
- a memory containing a table and storing a set of instructions for execution on the processor;
- wherein the set of instructions, when executed, causes the mobile station to:
- check a data packet received from a further mobile station;
- check a field of a media access control frame when a hardware address of the further mobile station is present in the table of the mobile station that received the data packet;
- store a value for adjusting a transmission power of the further mobile station based on a value in the field;
- and
- transmit to the further mobile station a next media access control frame that includes the value for adjusting the transmission power.
A mobile station, comprising:
- a processor;
- and
- a memory containing a table and storing a set of instructions for execution on the processor;
- wherein the set of instructions, when executed, causes the mobile station to:
- check whether a hardware address of a further mobile station to which a data packet is to be transmitted is present in the table of the mobile station;
- if the hardware address is present in the table, compare a signal strength associated with the further mobile station to a threshold signal strength;
- insert into the data packet a value for initiating a power adjustment in the further mobile station based on a result of the comparing;
- and
- after the inserting, transmit to the further mobile station the data packet.
A system, comprising:
- a first mobile station;
- a second mobile station;
- and
- an access point, the first mobile station including a processor provided with instructions for causing the first mobile station to:
- send a data packet destined for the second mobile station to the access point;
- listen for one of a transmission of the data packet by the access point to the second mobile station and a transmission of an acknowledgment by the second mobile station to the access point;
- add an address of the second mobile station to a table when the one of the listened for transmissions is detected;
- and
- send a further data packet destined for the second mobile station directly to the second mobile station when the address is present in the table.
