摘要： Techniques for paging user equipments (UEs) in a wireless communication system are described. In one aspect, a cell sends a paging indicator to a UE, monitors for an acknowledgement from the UE, and sends a page message to the UE if an acknowledgement is received from the UE. The cell may receive channel quality information from the UE and may send the page message with link adaptation and/or HARQ to improve performance. In another aspect, a cell sends a paging indicator on a shared control channel to a UE and sends a page message on a shared data channel to the UE. The paging indicator and page message may be sent from multiple cells to the UE. Alternatively, the paging indicator may be sent from multiple cells to the UE, and the page message may be sent from a single cell to the UE.

摘要： Techniques for sending messages for system access are described. In one aspect, a user equipment (UE) sends a first message with power headroom and/or buffer size information for system access. A Node B determines at least one parameter (e.g., a resource grant, power control information, etc.) based on the power headroom and/or buffer size information. The Node B sends a second message with the parameter(s). The UE sends a third message based on the parameter(s), e.g., with uplink resources indicated by the resource grant, with transmit power determined based on the power control information, etc. In another aspect, the UE sends a radio environment report in the third message. The report may be used to select a cell and/or a frequency for the UE. In yet another aspect, the second message includes power control information, and the UE sends the third message based on the power control information.

摘要： Systems and methodologies are described that facilitate employing constrained frequency hopping of downlink reference signals. Constrained frequency hopping of reference signals provides a sufficiently large set of frequency hopping patterns while enhancing channel estimation. Respective subsets of resource elements can be selected to carry reference signals from a plurality of antennas for a first subframe of a sequence. Further, respective subsets of resource elements used to carry reference signals from the plurality of antennas for a second subframe can be constrained based upon the respective subsets for the first subframe. Moreover, the first subframe frame and the second subframe (and similarly any additional subframes in the sequence) can be transmitted. An access terminal receiving the sequence of subframes can combine reference signals sent from common antennas at common frequency locations in the plurality of subframes and perform channel estimation as a function of the combined reference signals.

摘要： Systems and methodologies are described that facilitate employing periodic closed loop power control corrections in a wireless communication environment. A periodic power control command can be sent over a downlink to control and/or correct an uplink power level employed by an access terminal. Each periodic power control command can be generated based upon an uplink periodic transmission sent from the access terminal. The periodic power control commands can be communicated via a Physical Downlink Control Channel (PDCCH) or in-band signaling. Moreover, access terminals can be grouped to enhance efficiency of downlink transfer of the periodic power control commands. The periodic power control commands can be halted upon access terminal uplink resources being deallocated. For instance, these resources can be deallocated after an inactivity period of the access terminal. Thereafter, the access terminal can initiate random access (e.g., leveraging open loop mechanisms) to resume periodic power control command transmission.

摘要： Systems and methodologies are described that facilitate arrangement and transmission of control information in a wireless communication system. As described herein, a scheduled transmission of acknowledgement (ACK) signaling and channel quality information (CQI) signaling in a common subframe can be adapted for network implementations with limited link budget wherein ACK signaling is configured for repetition over multiple subframes to ensure a desired error rate level for the ACK signaling. To these ends, various aspects described herein facilitate modification of a coding rate applied to ACK signaling to be transmitted with data based on a repetition factor of the ACK signaling. Additionally and/or alternatively, various aspects described herein facilitate dropping of CQI signaling and transmission of only ACK signaling on subframes where CQI and ACK signaling are to be transmitted substantially simultaneously and ACK transmission is configured for repetition over multiple subframes.

摘要： Systems and methodologies are described that facilitate allocation of uplink acknowledgement (ACK) resources for a wireless communication system. Various aspects described herein facilitate explicit creation and transmission of a bundled assignment of downlink communication resources and uplink resources for ACK transmission, thereby facilitating overhead-efficient ACK allocation for users that can communicate pursuant to a persistent resource assignment without requiring scheduling information from an associated control channel. Additionally, indexing schemes for uplink ACK resources are provided herein to facilitate ACK allocation for systems in which both scheduled and persistent users can communicate at a common transmission time interval (TTI).

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： Multi-carrier point-to-multi-point CDMA system implementation reduces hardware changes in legacy single-carrier systems. The number of common downlink channels, such as timing/synchronization and paging channels, is reduced by designating an anchor carrier for transmitting these channels. Procedures for adding carriers and carrier acquisition are simplified through common carrier timing, signaling by the network to the user equipment (UE) of timing offsets and scrambling code selection, and other measures. Channel reuse is employed to minimize changes in asymmetric systems with different numbers of uplink and downlink carriers. Channel Quality Indicator (CQI) field is divided into multiple subfields to enable transmission of multiple CQIs and ACK/NACK indicators on one uplink carrier. Joint and separate scheduling schemes are shown for concurrent scheduling of a data stream transmission to a UE via multiple downlink carriers.
