Patent number: 11362872Abstract: Wireless communication techniques for transmitting and receiving reference signals is described. The reference signals may include pilot signals that are transmitted using transmission resources that are separate from data transmission resources. Pilot signals are continuously transmitted from a base station to user equipment being served.

Patent number: 9319928Abstract: A detailed design of an LTE Link Adaptation function for LTE uplink is disclosed. A new approach for adapting SINR backoff in OLLA is used when serving non-time-sensitive radio bearers without target BLER constraint. A sub-optimal scheduler is also disclosed wherein the SINR measurements at the ILLA input are updated on each TTI for the UEs scheduled in that sub-frame for future UL transmission with a fresher interference measurement from the sub-frame preceding by 8 ms the actual transmission sub-frame. This allows for exploitation of a correlation peak of the interference resulting from HARQ retransmissions. A schedule incorporating these features improves upon, with a minor complexity increase, the spectral efficiency performance of a low-complexity baseline scheduler only based on SINR updates at SRS rate.Type: GrantFiled: January 17, 2013Date of Patent: April 19, 2016Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Pierre Bertrand, Jing Jiang, Anthony Ekpenyong

Patent number: 9084242Abstract: This invention is a technique for coordinate multi-point wireless transmission between plural base stations and user equipment. At least one base station transmits via a Physical Downlink Shared CHannel (PDSCH). The user equipment does not know the identity of the plural base stations. This could include joint transmission by simultaneous data transmission from multiple base stations. This could include dynamic point selection by data transmission from one base station at a time and changing the transmitting point (TP) from one subframe to another subframe. This could include coordinated scheduling/beamforming (CS/CB) where data is transmitted to the user equipment from one base station at a time and the base stations communicate to coordinate user scheduling and beamforming. The transmission point (TP) could vary over Resource Block (RB) pairs within a subframe while never transmitting from more than one base station. The transmission point (TP) could change in a semi-static fashion.Type: GrantFiled: August 15, 2012Date of Patent: July 14, 2015Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Runhua Chen, Eko N. Onggosanusi, Anthony Ekpenyong, Vikram Chandrasekhar
