摘要： System(s) and method(s) are provided for inter-cell interference management in a wireless communication system. A base station perform interference management by conveying and receiving load indicator messages over a backhaul communication link to disparate neighboring base stations that serve interfering mobile stations. Reporting of load indicators takes place according to a reporting policy that is event-based, and accounts for variations of interference metrics over available time-frequency resources. Communication with neighboring base stations is limited to a monitoring interference set, which can be determined statically, according to deployment characteristics of a wireless network, or the set can be adjusted dynamically according to a set of received UL signals or a set of DL CQI measurement reports. Reporting policy and interference set can be autonomously adapted to optimize backhaul traffic as well as interference control.

摘要： Described herein are mechanisms and methods that facilitate preparation of inter-radio access technology (inter-RAT) and/or inter-frequency handover with respect to a mobile device (user equipment). User equipment can indicate to a network servicing the user equipment that the user equipment desires to perform measurements with respect to a different frequency and/or different technology. Data on the downlink channel can then be scheduled to ensure that data intended for the user equipment is not lost while the user equipment is performing the measurements.

摘要： Techniques for supporting communication on multiple carriers are disclosed. In one design, a user equipment (UE) is configured with a base carrier and a dependent carrier linked to the base carrier. Data transmission on the dependent carrier is scheduled via a scheduling carrier, which is different from the dependent carrier. The UE receives a scheduling grant on the scheduling carrier and determines whether the scheduling grant is for the base carrier and/or the dependent carrier. The UE communicates (e.g., sends or receives data) on the base carrier and/or the dependent carrier based on the scheduling grant. The scheduling grant may be (i) a separate grant carrying scheduling information for only one carrier, (ii) a common grant carrying scheduling information for both carriers, (iii) a joint grant carrying separate scheduling information for each carrier, or (iv) a composite grant that may be a separate grant, a common grant, or a joint grant.

摘要： Techniques for sending messages for system access are described. In one aspect, a user equipment (UE) sends a first message with power headroom and/or buffer size information for system access. A Node B determines at least one parameter (e.g., a resource grant, power control information, etc.) based on the power headroom and/or buffer size information. The Node B sends a second message with the parameter(s). The UE sends a third message based on the parameter(s), e.g., with uplink resources indicated by the resource grant, with transmit power determined based on the power control information, etc. In another aspect, the UE sends a radio environment report in the third message. The report may be used to select a cell and/or a frequency for the UE. In yet another aspect, the second message includes power control information, and the UE sends the third message based on the power control information.

摘要： Systems and methodologies are described that facilitate employing periodic closed loop power control corrections in a wireless communication environment. A periodic power control command can be sent over a downlink to control and/or correct an uplink power level employed by an access terminal. Each periodic power control command can be generated based upon an uplink periodic transmission sent from the access terminal. The periodic power control commands can be communicated via a Physical Downlink Control Channel (PDCCH) or in-band signaling. Moreover, access terminals can be grouped to enhance efficiency of downlink transfer of the periodic power control commands. The periodic power control commands can be halted upon access terminal uplink resources being deallocated. For instance, these resources can be deallocated after an inactivity period of the access terminal. Thereafter, the access terminal can initiate random access (e.g., leveraging open loop mechanisms) to resume periodic power control command transmission.

摘要： Techniques for accessing a wireless communication system are described. A user equipment (UE) sends a random access preamble for system access. The random access preamble may include a random identifier (ID), a channel quality indicator (CQI), etc. The UE may randomly select the random ID or may be assigned this random ID. The UE receives a random access response from a base station. The random access response may include control channel resources (e.g., CQI and PC resources), uplink resources, and/or control information (e.g., timing advance and PC correction) for the UE. The random access response may be sent in two parts using two messages. A first message may be sent on a control channel and may include identification information and possibly other information. A second message may be sent on a shared data channel and may include remaining information for the random access response.
