US Patent:
7876701, Jan 25, 2011
Filed:
Jul 8, 2008
Appl. No.:
12/169087
Inventors:
Junyi Li - Bedminster NJ, US
Rajiv Laroia - Far Hills NJ, US
Saurabh Tavildar - Jersey City NJ, US
Xinzhou Wu - Monmouth Junction NJ, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04L 12/26
H04L 12/28
US Classification:
370252, 370241, 370431, 370458
Abstract:
A protocol is provided that facilitates downlink concurrent peer-to-peer communications (within a time slot or traffic slot) between one device and many terminals as well as uplink concurrent peer-to-peer communications (within a time slot or traffic slot) between a plurality of terminals and one device. The concurrent peer-to-peer communications may take place within an ad hoc network of devices. To facilitate such operation, a time-frequency structure is provided within a control channel that allows the device and terminals to identify the peer-to-peer connections. This time-frequency structure also allows terminals to identify other sibling terminals that have a connection with the same device, thereby allowing to more efficiently performing interference mitigation. That is, sibling peer-to-peer connections with the same device may be treated different from other non-related peer-to-peer connects for purposes of interference mitigation in a wireless network.

Methods And Apparatus Supporting Traffic Signaling In Peer To Peer Communications

US Patent:
7898983, Mar 1, 2011
Filed:
Jul 5, 2007
Appl. No.:
11/773947
Inventors:
Rajiv Laroia - Far Hills NJ, US
Junyi Li - Bedminster NJ, US
Aleksandar Jovicic - Urbana IL, US
Thomas Richardson - South Orange NJ, US
Xinzhou Wu - Monmouth Junction NJ, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
G01R 31/08
US Classification:
370254, 370320, 370324, 370335, 370349, 342387, 342450, 342456, 342465, 455438, 455456, 4554566, 455561
Abstract:
Methods and apparatus related to peer to peer communication networks are described. An active connection list is maintained by a wireless communications device supporting peer to peer communications. In various embodiments, the active connection identifier list being maintained is in addition to a list of discovered peers in the local vicinity. Paging signaling, e. g. , peer to peer paging signaling, is used to establish active connections. Air link peer to peer traffic resources include traffic control resources and traffic data resources. A wireless communications device seeking to transmit on a traffic data resource transmits a traffic request signal on a traffic control resource. An active connection identifier is, in some embodiments, associated with a particular subset of traffic control resources. Thus, a wireless communications device monitors the portion or portions of the traffic control resource corresponding to its active connections for traffic request signals, but need not monitor other portions.

Methods And Apparatus For Controlling Interference To Broadcast Signaling In A Peer To Peer Network

US Patent:
7961698, Jun 14, 2011
Filed:
Jul 2, 2008
Appl. No.:
12/166645
Inventors:
Xinzhou Wu - Monmouth Junction NJ, US
Saurabh Tavildar - Jersey City NJ, US
Vincent D. Park - Budd Lake NJ, US
Junyi Li - Bedminster NJ, US
Rajiv Laroia - Far Hills NJ, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04B 7/208
H04L 12/28
H04J 3/26
US Classification:
370344, 37039542, 370432, 370462, 370480
Abstract:
Methods and apparatus related to broadcasting data and interference management in a peer to peer wireless communications network are described. Scheduling of traffic air link resources is performed on a slot by slot basis in a decentralized manner. Wireless devices intending to broadcast traffic signals transmit broadcast request signals, sometimes alternatively referred to as broadcast indicator signals. A priority level is associated with each of the broadcast request signals. A receiver device intending to receive broadcast signals detects the broadcast request signals and makes an interference determination as to whether the higher priority broadcast traffic signal can be successfully recovered in the presence of lower priority broadcast traffic signals. If the determination is that the expected interference from the lower priority broadcast traffic is unacceptable, the receiver device generates and transmits an interference control signal communicating to the lower priority device a command or request not to broadcast.

Coding Methods Of Communicating Identifiers In Peer Discovery In A Peer-To-Peer Network

US Patent:
7961708, Jun 14, 2011
Filed:
Jul 10, 2007
Appl. No.:
11/775787
Inventors:
Junyi Li - Bedminster NJ, US

Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04J 3/06
US Classification:
370350, 370304, 370324, 370503, 370328, 455 412, 455450, 455509, 4555521
Abstract:
Systems and methodologies are described that facilitate identifying peers based upon encoded signals during peer discovery in a peer to peer network. For example, direct signaling that partitions a time-frequency resource into a number of segments can be utilized to communicate an identifier within a peer discovery interval; thus, a particular segment selected for transmission can signal a portion of the identifier, while a remainder can be signaled based upon tones communicated within the selected segment. Moreover, a subset of symbols within the resource can be reserved (e. g. , unused) to enable identifying and/or correcting timing offset. Further, signaling can be effectuated over a plurality of peer discovery intervals such that partial identifiers communicated during each of the peer discovery intervals can be linked (e. g. , based upon overlapping bits and/or bloom filter information).

US Classification:
370235, 370348, 455509
Abstract:
Methods and apparatus for use in a wireless communications system in which traffic air link resources may be, and sometimes are, shared are described. Various described methods and apparatus are well suited for use in a peer to peer communications system in which transmission control decisions are made in a decentralized manner. An exemplary peer to peer communications system implements the scheduling of traffic intervals in a distributed manner utilizing connection priority information and interference information. An exemplary peer to peer timing structure includes a user scheduling interval and an associated traffic interval. The user scheduling interval includes a plurality transmission request/request response rounds. By utilizing multiple request/request response rounds, a transmission decision corresponding to a connection to yield in an earlier round can be overridden in a subsequent round, resulting in higher overall traffic throughput in the system.

Abstract:
In an ad hoc peer-to-peer communications network, timing synchronization is facilitated between two or more nodes. A node can establish an original symbol timing and receive a first timing synchronization symbol from a peer node. A timing adjustment can be calculated based in part on the first timing synchronization symbol. An adjusted symbol timing can be established by adjusting the first symbol timing by the calculated timing adjustment amount. The adjusted symbol timing can be conveyed to one or more peer nodes, in order to facilitate timing synchronization among the nodes.
