Abstract
Certain aspects provide a technique for managing transmissions in a wireless network. The technique generally provides for an access terminal to transmit synchronization packets containing timing information regarding an existing piconet. The synchronization packets may contain an indication of resources of the piconet allocated to the access terminal by an access point.
Claims58
A method of communication, comprising:
- receiving, from a node in a piconet, an allocation of resources for data transmissions in the piconet;
- and
- transmitting a synchronization packet containing information regarding the allocation of resources.
A method of communication, comprising:
- receiving, from a node in an existing piconet that is not acting as a piconet coordinator, a synchronization packet containing information regarding the allocation of resources in the piconet;
- and
- scheduling data transfers, based on the information contained in the synchronization packet, to avoid interference with data transfers in the existing piconet.
An apparatus of communication, comprising:
- a receiver for receiving, from a node in a piconet, an allocation of resources for data transmissions in the piconet;
- and
- a transmitter for transmitting a synchronization packet containing information regarding the allocation of resources.
An apparatus of communication, comprising:
- a receiver for receiving, from a node in an existing piconet that is not acting as a piconet coordinator, a synchronization packet containing information regarding the allocation of resources in the piconet;
- and
- a scheduler for scheduling data transfers, based on the information contained in the synchronization packet, to avoid interference with data transfers in the existing piconet.
An apparatus of communication, comprising:
- means for receiving, from a node in a piconet, an allocation of resources for data transmissions in the piconet;
- and
- means for transmitting a synchronization packet containing information regarding the allocation of resources.
An apparatus of communication, comprising:
- means for receiving, from a node in an existing piconet that is not acting as a piconet coordinator, a synchronization packet containing information regarding the allocation of resources in the piconet;
- and
- means for scheduling data transfers, based on the information contained in the synchronization packet, to avoid interference with data transfers in the existing piconet.
A computer-program product for communication, comprising a computer readable medium encoded with instructions executable to:
- receive, from a node in a piconet, an allocation of resources for data transmissions in the piconet;
- and
- transmit a synchronization packet containing information regarding the allocation of resources.
A computer-program product for communication, comprising a computer readable medium encoded with instructions executable to:
- receive, from a node in an existing piconet that is not acting as a piconet coordinator, a synchronization packet containing information regarding the allocation of resources in the piconet;
- and
- schedule data transfers, based on the information contained in the synchronization packet, to avoid interference with data transfers in the existing piconet.
An access point (AP) comprising:
- at least one antenna;
- a receiver for receiving via the at least one antenna, from a node in a piconet, an allocation of resources for data transmissions in the piconet;
- and
- a transmitter for transmitting, via the at least one antenna, a synchronization packet containing information regarding the allocation of resources.
A piconet coordinator (PNC) comprising:
- at least one antenna;
- a receiver for receiving via the at least one antenna, from a node in an existing piconet that is not acting as a piconet coordinator, a synchronization packet containing information regarding the allocation of resources in the piconet;
- and
- a scheduler for scheduling data transfers, based on the information contained in the synchronization packet, to avoid interference with data transfers in the existing piconet.
