Patent number: 9194902Abstract: Noise variance estimation and interference detection is described. In one example, a method of estimating noise variance is described in which the pilots within a received OFDM signal are divided into bands and then a noise variance estimate is calculated on a per-band basis by averaging the noise estimates for those pilots within the band. In some examples, the pilots are divided into bands in frequency and in other examples, the pilots are divided into bands in frequency and time, such that noise estimates from more than one OFDM symbol are used in calculating the per-band noise variance estimates. The noise variance estimate for a pilot is then set to the noise variance estimate for the band which contains the pilot. The noise variance estimate for a data sub-carrier can then be determined by interpolating between the values for the pilots.Type: GrantFiled: May 8, 2013Date of Patent: November 24, 2015Assignee: Imagination Technologies LimitedInventors: Paul Murrin, Mohammed El-Hajjar

Patent number: 8976730Abstract: For voice traffic over-the-air in LTE, persistent schedule (PS) or semi-persistent (SPS) scheduling would be the preferred method as they minimize signaling messages. In PS or SPS, resources are pre-allocated to the UE 402 at regular intervals (e.g., every 20 milliseconds). At each time slot, the UE will generally transmit an IMBE frames which are encoded in ISSI packet. In ISSI, other data streams are multiplexed with the IMBE frame and thus the packet size varies depending on its position within a super-frame. For PS or SPS, eNodeB must allocated sufficient resources to support the largest packet that. Therefore, there is spare capacity when the packet is not of the largest size. The exemplary embodiments specify ways to use spare capacity to transfer data.Type: GrantFiled: July 22, 2011Date of Patent: March 10, 2015Assignee: Alcatel LucentInventors: Thomas P.
