20080212561 | METHOD AND APPARATUS FOR ENHANCING RLC FOR FLEXIBLE RLC PDU SIZE - Enhancements are provided for the radio link control (RLC) protocol in wireless communication systems where variable RLC packet data unit (PDU) size is allowed. When flexible RLC PDU sizes are configured by upper layers, radio network controller (RNC)/Node B flow control, RLC flow control, status reporting and polling mechanisms are configured to use byte count based metrics in order to prevent possible buffer underflows in the Node B and buffer overflows in the RNC. The enhancements proposed herein for the RLC apply to both uplink and downlink communications. | 09-04-2008 |
20080225893 | ACKNOWLEDGED MODE RADIO LINK CONTROL ARCHITECTURE AND METHOD WITHIN EVOLVED HSPA SYSTEMS - An acknowledged mode (AM) radio link control (RLC) architecture and method within evolved high speed packet access (HSPA) are disclosed. The RLC is configured to operate in AM and process protocol data units (PDUs) of flexible size. Specifically, an AM RLC architecture and method in which RLC SDUs are segmented and/or concatenated only at the time of or immediately prior to delivering the PDUs to lower layers. This includes an interface with lower layers in order to support flexible PDU sizes for AM RLC. | 09-18-2008 |
20090023401 | METHOD AND APPARATUS FOR REDUCING TRANSIENT IMPACTS OF BEAM SWITCHING IN A SWITCHED BEAM ANTENNA SYSTEM - A method and apparatus for reducing transient impacts of beam switching in a switched beam antenna system are disclosed. A switch beam antenna system generates a plurality of beams in a predefined beam pattern and switches the current beam position to one of the plurality of predefined beams in accordance with measurement results for each of the beams. Quality of signals is periodically measured for each of the plurality of predefined beams, and the best beam is determined. The current beam is switched to either the best beam or an intermediate beam in accordance with the separation between the best beam and the current beam. | 01-22-2009 |
20090036063 | Distributed reservation protocol for enabling multi-band transmission in next generation ultra wide band technology - An ultra wide band wireless transmit/receive unit (WTRU) communication includes a transmitter configured to transmit a first indicator of a multi-radio band transmission, and a receiver configured to receive a second indicator of a multi-radio band transmission. | 02-05-2009 |
20090296619 | METHOD AND SYSTEM FOR EFFICIENT ADDRESSING AND POWER SAVINGS IN WIRELESS SYSTEMS - A method for addressing groups of stations in a wireless communication system begins by assigning the stations in the system into a number of groups. A group identifier is signaled to each station and the group identifier is indicated in a frame for each group that has data in the frame. The addressing method can be applied to power savings for the station, wherein the station enters a power saving mode if the group identifier for the station is not present in the frame. | 12-03-2009 |
20120093134 | METHOD AND APPARATUS FOR EXCHANGING CONTROL OF A TRANSMISSION OPPORTUNITY - Methods and apparatus are disclosed. A method implemented in a wireless transmit/receive unit (WTRU) includes receiving a packet from a first other WTRU during a transmission opportunity (TxOP) associated with the first other WTRU and forwarding the packet to a second other WTRU during a remaining portion of the TxOP. | 04-19-2012 |
20130165054 | METHOD AND APPARATUS FOR MEASURING INTERFERENCE IN WIRELESS STATIONS - A method for use in a station of measuring radio frequency (RF) interference is presented. An average noise power indicator of the STA (STA_ANPI) is determined. A rate of change of the STA_ANPI is monitored to determine an RF interference metric. The RF interference metric is transmitted to another network entity, whereby the another network entity is enabled to perform load balancing based on the RF interference metric. | 06-27-2013 |
