The processor may be configured to maintain in the memory a database containing a list of access points that have previously served the access terminal with at least a minimum quality of service, the processor being further configured to use the list to search for an access point to associate with, or search for an access point to handoff the access terminal to during operation. In addition to, or alternatively, the processor may also be configured to maintain in the database a second list of access points. The database may be used by the processor to search for an access point that is not on the second list to associate with, or handoff the access terminal to.

摘要： Systems and methodologies are described that facilitates managing assignment of available random access resources in order to minimize delay and random access load. A number of available random access resources can be defined by a network or a base station, wherein a user equipment can access the number of available random access resources via an information block. The user equipment can be randomly assigned or uniformly assigned to at least one of the number of available random access resources. Additionally, the network can adjust the defined number of available random access resources based upon reported delay, base station load, or historic load data for a base station.

摘要： Systems and methodologies are described that facilitate effectuating a random access procedure in a wireless communication environment. A random access preamble can be sent from an access terminal to a base station, and a random access response can be sent from the base station to the access terminal in response. The random access response can allocate resources to be utilized by the access terminal for a scheduled transmission (e.g., message 3, . . . ). Further, a plurality of Transmission Time Intervals (TTIs) can be bundled for the scheduled transmission. Moreover, a payload of the scheduled transmission can be transmitted to the base station from the access terminal within a common Transport Block (TB) using the bundled plurality of TTIs. According to an example, employment of TTI bundling can be controlled on a per network basis, per base station basis, or per access terminal basis.

摘要： Techniques to support beamforming for stations in a wireless network are described. In one aspect, a station may support beamforming with implicit feedback or explicit feedback by having capabilities to transmit and receive sounding frames, respond to training request by sending a sounding frame, and respond to request for explicit feedback. In one design of explicit beamforming, the station may send a first frame with a request for explicit feedback and may also send a Null Data Packet (NDP) having at least one training field but no data field. The station may receive a second frame with the explicit feedback, which may be derived based on the NDP. The station may derive steering information (e.g., steering matrices) based on the explicit feedback and may then send a steered frame with beamforming based on the steering information. The station may also perform implicit beamforming using NDP for sounding.

摘要： Techniques for supporting random access by user equipments (UEs) in a wireless communication system are described. In one design, a UE transmits a random access (RA) preamble for random access. The UE thereafter receives a random access response composed of a first part and a second part. The first part includes a list of N RA preamble IDs for N RA preambles being responded to by the random access response, where N≧1. The second part includes N individual RA responses for the N RA preambles being responded to. The UE processes the first part to detect for an RA preamble ID of the RA preamble transmitted by the UE. If this RA preamble ID is not detected, then the UE skips the second part. Otherwise, the UE processes the second part to obtain an individual RA response for the transmitted RA preamble.

摘要： A scheduled data communication system of an access node and terminal supports recurring communications of small data amounts such as Voice over IP (VoIP). In order to make error checking more robust in a random access response (RAR), such as for semi-persistent scheduling (SPS) for VoIP, a portion of a grant or assignment payload has a constraint imposed that can be verified as a condition precedent to determining a valid grant or assignment rather than only relying upon a validity check field, such as a cyclic redundancy check (CRC). Thereby, incorrect validation of a grant or assignment is avoided for dynamic scheduling or for semi-persistent scheduling, the latter causing a persistent error.

摘要： Techniques for selecting rates for data transmission on eigenmodes of a MIMO channel are described. An access point transmits an unsteered MIMO pilot via the downlink. A user terminal estimates the downlink channel quality based on the downlink unsteered MIMO pilot and transmits an unsteered MIMO pilot and feedback information via the uplink. The feedback information is indicative of the downlink channel quality. The access point estimates the uplink channel quality and obtains a channel response matrix based on the uplink unsteered MIMO pilot, decomposes the channel response matrix to obtain eigenvectors and channel gains for the eigenmodes of the downlink, and selects rates for the eigenmodes based on the estimated uplink channel quality, the channel gains for the eigenmodes, and the feedback information. The access point processes data based on the selected rates and transmits steered data and a steered MIMO pilot on the eigenmodes with the eigenvectors.
