    摘要: Techniques for transmitting random access signaling for system access are described. In an aspect, random access signaling may be sent based on at least one transmission parameter having different values for different user equipment (UE) classes. At least one parameter value may be determined based on a particular UE class, and the random access signaling may be sent based on the determined parameter value(s). The random access signaling may be a random access preamble, and the at least one transmission parameter may include a target SNR, a backoff time, and/or a power ramp. The random access preamble may then be sent based on a target SNR value, a power ramp value, and/or a backoff time value for the particular UE class. In another aspect, a message for system access may be sent based on a power control correction received in a random access response for the random access preamble.

    摘要: Communication in a dominant interference scenario may be supported by performing inter-cell interference coordination (ICIC). Resource coordination/partitioning may be performed to allocate resources to a serving Node B located near the vicinity of a strong interfering Node B. The interfering Node B may avoid transmitting on the allocated/protected resources, possibly except for a common reference signal (CRS). A UE can then communicate with the serving Node B on the protected resources in the presence of the interfering Node B and may observe no interference (possibly except for the CRS) from the interfering Node B. When CRS tones of an interferer may collide with control/data tones of a serving cell, CRS interference cancellation (CRS IC) or puncturing of interfered resource elements (REs) may be appropriate. Certain aspects of the present disclosure provide techniques, where the UE may dynamically switch between CRS IC and RE puncturing based on certain parameters.

    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: For range expansion, a determination to enter range expansion may be made based on a signal strength differential for user equipment (UE) communications between a first class of base stations and a second class of base stations. If the signal strength differential is beyond a certain threshold, range expansion may be implemented. In range expansion, a signal is transmitted, on a resource coordinated with at least one of the first class of base stations, from one of the second class of base stations to the UE which could experience dominant interference from one of the first class of base stations if coordination were not performed. Transmission power may be reduced from one of the first class of base stations on that resource. The second signal may be transmitted within the region of the Physical Downlink Shared Channel.

    摘要: Discontinuous reception (DRX) operation may be utilized to maintain connection with user equipment (UE) by increasing the effective control channel transmission periodicity. UEs may be configured with a compatible control channel transmission periodicity such that multiple UEs may share a resource in a time-division-multiplexed manner using DRX offsets and periodicity, effectively extending control channel transmission periodicity through resource overloading.
