Patent number: 9516663Abstract: Transmission of information in a wireless network is performed by allocating a channel from a transmitter to a receiver. The channel has at least one time slot with each time slot having a plurality of symbols. Each slot contains at least one reference symbol (RS). As information becomes available for transmission, it is classified as prioritized information (PI) and other information. One or more priority symbols are generated using the digital samples of the priority information. Other symbols are generated using the other data. Priority symbols are transmitted on the channel in a manner that separation of priority symbol(s) and a reference symbol does not exceed a time duration of one symbol. For example, Rank Indicator (RI) is transmitted using symbol k, ACKNAK is transmitted using symbol k+1; and the reference signal (RS) is transmitted using symbol k+2, wherein symbols k, k+1, and k+2 are consecutive in time. The other symbols are transmitted in available locations.Type: GrantFiled: June 7, 2012Date of Patent: December 6, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Tarik Muharemovic, Zukang Shen, Pierre Bertrand, Eko Nugroho Onggosanusi

Patent number: 9474055Abstract: A method for allocating resources for a scheduling request indicator (SRI) is disclosed. An SRI cycle period for use by user equipment (UE) within a cell is transmitted from a NodeB in a cell to UE within the cell. The NodeB transmits a specific SRI subframe offset and an index value to the particular UE within the cell. The specific SRI subframe offset and the index value enable the UE to determine a unique combination of cyclic shift, RS orthogonal cover, data orthogonal cover, and resource block number for the UE to use as a unique physical resource for an SRI in the physical uplink control channel (PUCCH).Type: GrantFiled: August 5, 2014Date of Patent: October 18, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Pierre Bertrand, Zukang Shen, Tarik Muharemovic

Patent number: 9313062Abstract: Transmitting a acknowledge/not acknowledge (ACK/NACK) response in a wireless cellular network by mapping the data value into a cyclic shifted version of a reference signal. A subframe is formed with a plurality of symbols with certain symbols designated as reference signal (RS) symbols. The receiver and transmitter both know when an ACK/NACK response is expected. If an ACK/NACK response is not expected, then an RS is inserted in the duration of symbols designated as RS symbols. If an ACK/NACK response is expected, then the ACK/NACK response is embedded in one or more of the symbols designated as RS symbols. The subframe is transmitted to a receiver, and the receiver can determine the ACK/NACK value in the RS symbol, if present, and also use the RS symbol for coherent demodulation of a CQI (channel quality indicator) or data.Type: GrantFiled: September 26, 2013Date of Patent: April 12, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Tarik Muharemovic, Zukang Shen, Pierre Bertrand

Patent number: 9166717Abstract: A cell within cellular network includes user equipments (UEs) that transmit data to a base station (eNB). Over a period of time, not all of the UEs will have data to transmit. The UEs are tracked as a scheduled portion and an unscheduled portion, wherein a UE is included in the scheduled portion in response to receiving a scheduling request from the UE. Synchronization is maintained between the eNB and each UE in the scheduled portion by sending a timing adjustment (TA) command if needed. Synchronization is maintained between the eNB and each UE in the unscheduled portion by allocating a periodic reference signal (sync-RS) to each UE in the unscheduled portion and by sending a respective timing adjustment (TA) command if needed to each respective UE in the unscheduled portion in response to a respective sync-RS received from each UE in the unscheduled portion.Type: GrantFiled: June 22, 2012Date of Patent: October 20, 2015Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Pierre Bertrand, Tarik Muharemovic, Zukang Shen

Patent number: 9113460Abstract: A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations on an uplink channel in a wireless network. A scheme for mapping between logical uplink control channel (PUCCH) resource blocks (RBs) and physical RBs (PRBs) used by PUCCH is described. A logical uplink control resource block index nLRB is derived by the secondary node in response to information from the primary node. The secondary node then maps the logical uplink control resource block index nLRB to a first uplink physical resource block index nPRB,1 of a plurality of uplink physical resource blocks, wherein nPRB,1=nLRB/2 if nLRB is even and nPRB,1=NPRB?ceil(nLRB/2) if nLRB is odd; wherein NPRB is the total number of the plurality of uplink physical resource blocks; and wherein ceil denotes the ceiling operation. The secondary node then transmits an uplink control information in a subframe using one of the plurality of uplink physical resource blocks indexed by nPRB,1.Type: GrantFiled: January 14, 2014Date of Patent: August 18, 2015Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Zukang Shen, Tarik Muharemovic, Jing Jiang

Patent number: 9094169Abstract: A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations. The transmission from the secondary to primary node in a wireless network is obtained using an orthogonal covering sequence and a second sequence. Embodiments of the present invention mitigate interference by calculating a first orthogonal covering (OC) index and a second OC Index from an indicator received from a serving base station (NodeB). A first index n1 is derived and a second index n2 is derived using the first index n1. A first orthogonal covering (OC) index and a first cyclic shift (CS) is determined using the derived index n1. A second OC and a second CS is derived using the derived index n2. A first slot of a subframe is generated using the OC indexed by the first OC index and the first CS and a second slot of the subframe is generated using the OC indexed by the second OC index and the second CS.Type: GrantFiled: July 8, 2014Date of Patent: July 28, 2015Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Zukang Shen, Tarik Muharemovic, Pierre Bertrand

Patent number: 8942080Abstract: This invention is applicable to wireless communication between a user equipment (UE) and a base station using frames where at least one uplink (UL) is assigned a subframe to respond to a plurality of DL assigned subframes. This invention is an improvement in the acknowledge (ACK) or non-acknowledge (NAK) response by the UE. The UE generates an ACK or NAK dependent upon whether a DL communication is correctly received. For an UL subframe assigned to respond to communications on plural DL subframes, the UE logically combines plural ACK/NAK responses into a single bundled response for transmission to the base station. This logical combining produces a bit in a first digital state if all said responses are ACKs and in a second opposite digital state if any response is a NAK.Type: GrantFiled: April 17, 2009Date of Patent: January 27, 2015Assignee: Texas Instruments IncorporatedInventors: Zukang Shen, Tarik Muharemovic, Eko Nugroho Onggosanusi
