Abstract: A method of reducing the usable channel bandwidth and increasing the channel bandwidth at run time is provided. The method allows a receiving wireless communications device to inform its corresponding transmitting communications device to either increase, reduce, or maintain the number of usable narrow band channels for the succeeding frame exchange. In a wireless communications channel, channel reduction is accomplished by using a usable channel indicator in a response frame responding to the preceding receiving frame. The usable channel indicator is the means for the receiving communications device to inform the transmitting communications device the preferred narrow band channels that it deems having good channel characteristics.

Abstract: The invention relates to a method for transmitting a periodic channel quality report (CSI) and/or a sounding reference symbol (SRS) from a UE to an e Node B. To avoid double decoding at the e Node B in transient phases, a deterministic behavior of the UE is defined by the invention, according to which the e Node B can unambiguously determine whether the UE will transmit the CSI/SRS or not. According to one embodiment, the UL grants and/or DL assignments received until and including subframe N?4 only are considered; UL grants and/or DL assignments received by the UE after subframe N?4 are discarded for the determination. Additionally, DRX-related timers at subframe N?4 are considered for the determination. In a second embodiment, DRX MAC control elements from the e Node B, instructing the UE to enter DRX, i.e. become Non-Active, are only considered for the determination if they are received before subframe N?4, i.e. until and including subframe N?(4+k).

Abstract: A wireless network includes first-configuration sectors with a first frequency assignment and second-configuration sectors with a second frequency assignment. When served by a first-configuration sector that borders a second-configuration sector, the mobile station receives (i) a neighbor list that identifies neighbor sectors of the primary sector, including the second-configuration sector, (ii) a primary-sector reference distance between a transmitter for the primary sector and a reference point in the primary sector, and (iii) a neighbor-sector reference distance between a transmitter for the second-configuration sector and the reference point. Based on the reference distances, the mobile station calculates a border distance between the primary sector's transmitter and a border between the sectors. The mobile station compares its distance from the primary sector's transmitter to the primary-sector reference distance and/or border distance.
