In some wireless systems (e.g., new radio (NR) systems), a system may employ fixed or variable length uplink burst regions (e.g., in an uplink-centric slot). The base sta- tion may semi-statically or dynamically configure a user equipment (UE) or group of UEs for uplink control channel transmissions with- in an uplink burst region. In semi-static configuration, the UE may determine the uplink control channel transmission based on values transmitted or indicated via higher-layer signaling or based on de- fault values. In dynamic configuration, the UE may receive an indi- cation of actual resources used by the base station in a physical lay- er message. The UE may transmit using an uplink control channel transmission based on the indication. In some cases, the base sta- tion may allocate code division multiplexing (CDM) groups based on which UEs are semi-statically configured and which are dynam- ically configured.

Abstract: Techniques for performing time tracking at a receiver are described. A first arriving path (FAP) and a last arriving path (LAP) are detected based on a channel impulse response estimate for a communication channel. The detected FAP and LAP may be correct or swapped. To resolve ambiguity in the detected FAP and LAP, a first hypothesis corresponding to the FAP and LAP being correctly detected and a second hypothesis corresponding to the FAP and LAP being incorrectly detected are evaluated. For each hypothesis, hypothesized FAP and LAP are determined based on the detected FAP and LAP, a correlation window is determined based on the hypothesized FAP and LAP, and correlation is performed using the correlation window. The correct hypothesis is determined based on correlation results for the two hypotheses. The receiver timing is updated based on the hypothesized FAP and LAP for the correct hypothesis and used for demodulation.

Abstract: In an antenna diverstiy environment, the timing offset of the receiver's fingers are based on the timing offset of the received peaks of the base station transmit signals. In a system with non-neglible multipath spacing, the timing offset of the received peaks of the base station transmit signals are not necessarily at the same location. In one embodiment, the demodulating elements for the signal from each base station antenna use the same offset for demodulating and determining an error signal based on pilot signal sampling prior to the timing offset and subsequent to the timing offset. The error signals are averaged and used by a time trackin loop to track the incoming signal. In another embodiment, the demodulating elements for the signal from each base station antenna independently time track the signals with different times offsets for each finger. The preferred embodiment depends on the method used by the base station to multiplex the data onto multiple transmit antennas.

Abstract: Techniques to detect for DTX frames in a "primary" transmission that may be sent in a non-continuous manner using a "secondary" transmission that is sent during periods of no transmission for the primary transmission. The primary and secondary transmissions may be the ones sent on the F-DCCH and Forward Power Control Subchannel, respectively, in an IS-2000 system. In one method, a determination is first made whether or not a frame received for the primary transmission in a particular frame interval is a good frame (e.g., based on CRC). If the received frame is not a good frame, then a determination is next made whether the received frame is a DTX frame or an erased frame based on a number of metrics determined for the primary and secondary transmissions. The metrics may include symbol error rate of the received frame, secondary transmission (e.g., PC bit) energy, and received frame energy.

Abstract: A system for efficiently employing a quick paging channel signal to determine the presence of a forthcoming primary paging channel in a wireless communications system employing a quick paging channel and a primary paging channel. The system includes a first mechanism for selectively processing a first quick paging channel symbol and/or a second quick paging channel symbol of a received signal based on a first decision parameter and/or a second decision parameter and providing a first indication in response thereto. A second mechanism processes the first quick paging channel symbol in response to the first indication and provides a second indication in response thereto indicating whether a forthcoming primary paging channel signal should be received and processed. A third mechanism processes the second quick paging channel symbol in response to the first indication and the second indication and provides a third indication in response thereto specifying whether the primary paging channel should be received an processed. In a specific embodiment, the system is adapted for use with a mobile station and further includes a fourth mechanism for selectively employing the third mechanism when the second indication does not indicate that the forthcoming primary paging channel should be received and processed. The first decision parameter CSI1 is representative of a quality of a signal environment through which the received signal propagates and is described by the equation (I) where E pilot1 represents the normalized pilot energy of a portion of the pilot signal associated with the first quick paging symbol, and Î o1 represents a total energy of a portion of the received signal associated with the first quick paging symbol.
