Abstract: A smoothing algorithm for round trip time (RTT) measurements is provided to a network device to effectively deal with variations or other potential anomalies that may occur in RTT measurements. The algorithm involves: first determining what should be considered a very high or a very small value for a RTT sample. If a new RTT sample is in an acceptable range, then the network device performs a relatively basic smoothing. If the new RTT sample is much higher than a current RTT value, then the network device ignores the value of this RTT sample a few times. If the network device still detects this large value after ignoring that value for some time, then the network device factors this value into the current RTT value using an additive increase. Similarly, if the value of the new RTT sample is much lower than current RTT value, the network device ignores the value of the new RTT sample a few times.

Abstract: The present invention relates to allowing configuring CSI reporting (step S-224, 310) on radio resources that are allocated over a plurality of sub frames on Physical Uplink Shared Channel (PUSCH). Allocation of said radio resources (steps S-202, 404) can be performed by semi-persistent allocation or by using Transmission Time Interval (TTI) bundling. By using either semi-persistent scheduling or TTI-bundling as decided by an eNB (104, 204, 600) the UE (102, 202, 500) can be configured to report CSI (step S-224, 310) for a plurality of UL transmissions. By allocating radio resources by using semi-persistent scheduling, the signaling overhead, which can be substantial for dynamic scheduling of radio resources, decreases. By using TTI-bundling the coverage of the CSI-reports increases.

Abstract: In the MS apparatus for performing scheduling, a reception module receives any number information through a specific downlink channel in a first time unit from each of neighbor BSs. A scheduling module determines, among the neighbor BSs, a BS which is to transmit and receive data using a downlink data transmission region and an uplink data reception region, respectively, in a second time unit according to a previously set rule based on the number information. A transmission module transmits a signal, indicating that data transmission and reception using the downlink transmission region and uplink data reception region, respectively, in the second time unit are not possible, to the other neighbor BSs excluding the determined BS among the neighbor BSs.
