摘要： Systems and methodologies are described that facilitate mitigating effect of non-linear distortion from a power amplifier on a spectral mask margin. Power limit indications can be analyzed in scheduling mobile devices. Mobile devices with power limits can be scheduled on inner subbands. Other mobile devices can employ remaining portions of an allocated spectrum. Further, mobile devices can evaluate and establish a power amplifier backoff based upon the subband scheduling.

摘要： A method and a corresponding apparatus for data transmission during a sticky assignment of a transmit resource in a communication system is described, the method comprising determining if any transmit data packets are queued and ready to be transmitted, transmitting the data packets using the assigned resource, if it is determined that one or more data packets are ready for transmission and transmitting a predetermined erasure signature packet using the assigned resource, if it is determined that no data packets are ready for transmission. Also the corresponding reception method and apparatus arc described.

摘要： Signaling-only access may be established with an access node (104) under certain circumstances such as, for example, upon determining that a node (102) is not authorized for data access at the access node (102). A node (104) that is not authorized for data access at an access node (104) may still be paged by the access node (104) through the use of signaling-only access. In this way, transmissions by the access node (104) may not interfere with the reception of pages at the node (302). A first node may be selected for providing paging (102) while a second node (106) is selected for access (304) under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.

摘要： Providing for base station (BS) acquisition in semi-planned or unplanned wireless access networks is described herein. By way of example, a signal preamble can be dynamically allocated to wireless signal resources, such that the preamble is scheduled to different resource(s) across different cycles of the signal. Dynamic allocation can be pseudo-random, based on collision feedback, or determined by a suitable algorithm to mitigate collisions from a dominant interferer. In addition, dynamic scheduling can be particular to a type of BS to significantly reduce collisions from BSs of disparate types. In at least one aspect, a preamble resource can be subdivided into multiple frequency sub-carrier tiles. Control channel information can be transmitted on each tile of a group of such tiles, further mitigating effects of a dominant interferer on a subset of the tile group.

摘要： Systems and methodologies are described that facilitate grouping pilot identifies to indicate type and/or classification information regarding one or more access points. The access points can select or be assigned pilot identifiers from the group indicating a type or classification related to the access points. Thus, identifiers can be grouped into macrocell and/or femtocell groups or ranges such that an access point can indicate, and mobile devices can efficiently determine, whether the access point provides macrocell or femtocell coverage based on a range from which its pilot identifier is selected or assigned. In addition, the pilot identifiers can be utilized to indicate restricted association information regarding the access points.

摘要： Systems and methodologies are described that facilitate transmitting control information in wireless networks. Portions of bandwidth can be blanked for transmitting control information, and the control information transmitters can utilize beacon symbols to convey the control information. In this regard, interference is mitigated with respect to data transmissions over the control information bandwidth. Selected frequencies of the beacon symbols in a codeword can be used to indicate the control information. The codewords can be encoded with an error control code to provide redundancy for decoding in the presence of some interference.
