Abstract: Wireless user equipment (UE) operating in a wireless communication system may operate in a state, for example, the CELL_FACH state in UMTS, that does not allow for soft handoff from one cell to another. This inability to engage in soft handover may lead to intercell interference at a non-serving cell when the UE transmits on its uplink in close proximity to the non-serving cell. Therefore, provided in the present disclosure is method of wireless communication, which includes receiving a neighbor cell identification set indicating one or more neighbor cells, receiving a relative grant channel resource index corresponding to a relative grant channel shared by at least one of the one or more neighbor cells, detecting intercell interference associated with a user equipment (UE) in the one or more neighbor cells, and transmitting a non-serving relative grant message to the UE on the relative grant channel.

Abstract: Aspects describe dynamically adjusting a reordering release timer to mitigate latency in a MAC-hs queue. Information already available at a mobile device is utilized for current packets and for missing packets to dynamically adjust the value of the T1 timer in an effort to mitigate latency. Further, the network might provide information regarding HARQ attempts, which mobile device can utilize for computing the dynamic value of the T1 timer. The network might signal the amount of time the mobile device should subtract from timer T1 for every HARQ transmission. Further, the T1 timer might only be dynamically adjusted for a subset of radio bearers.

Abstract: A small base node such as a Home Base Node (HNB), or femto cell, may reduce its transmit power in order to prevent co-channel or adjacent channel interference, or to limit its coverage area. Once the power is set, the HNB signal to a served Home User Equipment (HUE) its transmit Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as Random Access Channel (RACH) constant value) to compensate for the error in signaled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, to prevent interference, parameters would also be adjusted and signaled to the HUE to reflect the link imbalance.

Abstract: Processing associated with ranging operations is shifted from a first apparatus to a second apparatus. For example, upon sampling a received ranging signal (e.g., a pulse) from the second apparatus, the first apparatus does not process the ranging signal to identify a relatively precise time of arrival estimate. Instead, the first apparatus sends sample data (e.g., representative of the power and/or magnitude of the received signal) and associated timestamp information to the second apparatus. The second apparatus processes the received sample data and timestamp information to determine the time of arrival estimate on behalf of the first apparatus. The second apparatus then uses this time of arrival estimate to determine the distance between the apparatuses.
