摘要： Techniques for transmitting pilot and traffic data are described. In one aspect, a terminal may scramble its pilot with a scrambling sequence generated based on a set of static and dynamic parameters. The static parameter(s) have fixed value for an entire communication session for the terminal. The dynamic parameter(s) have variable value during the communication session. The terminal may generate a scrambling sequence by hashing the set of parameters to obtain a seed and initializing a PN generator with the seed. The terminal may then generate the pilot based on the scrambling sequence. In another aspect, the terminal may use different scrambling sequences for pilot and traffic data. A first scrambling sequence may be generated based on a first set of parameters and used to generate the pilot. A second scrambling sequence may be generated based on a second set of parameters and used to scramble traffic data.

摘要： Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.

摘要： A method of wireless communication determines a UE interference condition during handover. A target cell receives information that indicates an interference condition of a user equipment (UE). Prior to completing handover, the target cell determines an expected UE interference condition that will arise after completing the handover of the UE at a target base station. The information can be determined based on a message from the UE. The UE message may indicate which cell is the strongest, indicate the interference condition at both the source and target cells, or only provide a measurement of the strongest cell. Based on the UE measurements, the target eNodeB may schedule the UE on resources based on the expected interference condition at the UE that may arise after the handover.

摘要： Aspects of the present disclosure may simplify the negotiation of resources by defining and/or using sequences for sets of resources for enhanced inter-cell interference coordination. According to aspects, a configuration of protected resources may have an ordering such that a pattern representing ‘k’ protected resources overlaps with a pattern representing ‘k+1’ protected resources. In an aspect, each pattern may comprise a bitmap with one or more bits set to a value to indicate the one or more protected subframes. In an aspect, a bitmap of a pattern corresponding to ‘k’ protected subframes differs from a bitmap of a pattern corresponding to ‘k+1’ protected subframes by a single bit value. According to aspects, an interfering evolved Node B may limit transmissions during protected subframes based on the selected pattern.

摘要： Aspects are disclosed for facilitating a timing alignment in a multicarrier system. In one aspect, at least one downlink timing associated with at least one downlink carrier is determined, and an uplink timing associated with an uplink group of carriers is ascertained based on at least one downlink timing and a timing offset associated with the uplink group of carriers. Each of the uplink group of carriers is then transmitted within a threshold value of the uplink timing. In another aspect, a downlink communication is transmitted to a wireless terminal via at least one downlink carrier. This embodiment further includes assigning a timing offset to an uplink group of carriers, and providing the timing offset to the wireless terminal via the at least one downlink carrier. An uplink communication is then received via the uplink group of carriers according to the timing offset.
