Publication number: 20200059323Abstract: 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: ApplicationFiled: October 28, 2019Publication date: February 20, 2020Inventors: Tarik Muharemovic, Zukang Shen, Pierre Bertrand, Eko N.

Publication number: 20190334645Abstract: Embodiments of the invention are directed to a cellular communication network that can determine whether communications between one base station-UE pair may interfere with another UE that is in the same cell or a different cell. The network identifies interference parameters associated with interference signals that may be received by a UE. The interference signals may be generated by the base station itself, such as communications with other UEs, or by a neighboring base station. The base station transmits the interference parameters to the UE. The UE receives the one or more parameters comprising information about signals expected to cause intra-cell or inter-cell interference. The UE then processes received signals using the one or more parameters to suppress the intra-cell or inter-cell interference.Type: ApplicationFiled: July 8, 2019Publication date: October 31, 2019Inventors: Runhua Chen, Eko N.

Patent number: 9807789Abstract: Embodiments of the invention provide methods for maximizing the bandwidth utilization in the uplink of a communication system supporting time division multiplexing between unicast and multicast/broadcast communication modes during transmission time intervals in the downlink of a communication system. This is accomplished by multiplexing at least unicast control signaling for UL scheduling assignments in TTIs supporting the multicast/broadcast communication mode. Moreover, multiplexing of unicast control signaling can also be accomplished by splitting a symbol of the multicast/broadcast TTI into two shorter symbols with the first of these two shorter symbols carrying at least unicast control signaling and the second of these shorter symbols carrying multicast/broadcast signaling.Type: GrantFiled: August 31, 2015Date of Patent: October 31, 2017Assignee: Intel CorporationInventors: Aris Papasakellariou, Timothy M.
