摘要： A base station is provided. The base station includes a transmit path circuitry that generates a masking sequence to mask a cyclic redundancy check of a control channel information element. The masking sequence includes a 4-bit prefix. The three least significant bits of the 4-bit prefix indicate a message type of the control channel information element. A subscriber station is also provided. The subscriber station includes a receive path circuitry that determines a message type of a control channel information element using a three least significant bits of a 4-bit prefix of a masking sequence used to mask a cyclic redundancy check of the control channel information element.

摘要： When a subscriber station (SS) encounters interference caused an interfering base station (BS), the interference can be mitigated regardless of whether the interfering base station is a CSG-Closed BS or whether the SS is connected to a serving BS. If the SS is not connected to a serving BS and cannot access the interfering BS, the SS will signal the interfering BS directly to request the interfering BS to perform IM. If the SS is a legal user, and conditions to initiate IM are met, the interfering BS will perform IM until conditions to terminate IM are met. If the SS is connected to a serving BS, the serving BS will request the interfering BS to perform or terminate interference mitigation (IM) on behalf of the SS if certain conditions are satisfied.

摘要： A base station for use in a wireless network that communicates with mobile stations according to the IEEE 802.16m standard. The base station transmits unicast data and E-MBS data in the downlink to mobile stations using physical resource units (PRUs) that are partitioned into a plurality of frequency partitions. The base station transmits E-MBS data using a first set of PRUs in at least a first common frequency partition, wherein the first set of PRUs are also used by at least a second base station to transmit E-MBS data. The base station further transmits unicast data using a second set of PRUs, wherein the second set of PRUs are randomized with respect to PRUs used by the at least a second base station to transmit unicast data.

摘要： A base station and subscriber station are capable of communicating with each other in a wireless communication network. The base station allocates resources to the subscriber station through resource allocation messages included in a resource allocation region of a downlink communication. The resource allocation region is partitioned into a plurality of sub-regions. Conventions regarding the arrangement of the resource allocation messages are disclosed which enable the subscriber station to decode the resource allocation messages contained in a sub-region and cease decoding operations upon reaching the end of the sub-region. Accordingly, the subscriber station does not decode resource allocation messages contained in subsequent sub-regions.
