Abstract: Example embodiments are directed to a method including transmitting, by a small cell, a pilot signal to a user equipment (UE) based on a first training signal received from the UE, and receiving, by the small cell, a second training signal from the UE. The second training signal is offset by a time based on the pilot signal transmitted by the small cell.

Abstract: A content adapter receives a request from a first user equipment to receive a unicast service via a base station and determines that the base station is providing the unicast service to a second user equipment using a service identifier. The content adapter transmits a signal instructing the base station to allocate the service identifier to the first user equipment for receiving the unicast service concurrently with the second user equipment. A base station allocates the service identifier to the first user equipment in response to the first user equipment requesting a unicast service that the base station is already providing to a second user equipment using the service identifier. The base station transmits content for the unicast service for reception by the first and second user equipment based on the service identifier.

Abstract: For applications with very small data activities, connection of a UE to a wireless network for sending or receiving such small data traffic increments via conventional connection set-up processes is quite inefficient in terms of spectral resource utilization. The invention provides a new connectionless methodology for transmission of such small data increments between a UE and a serving eNB. In particular, the invention methodology contemplates identifying a set of preamble sequences among the pool of preamble sequences provided for access requests from a UE to an eNB via the Random Access Channel as corresponding to a request from the UE for access to transmit an increment of data smaller than a predetermined threshold data size. When a UE has data traffic to transmit of a size smaller than the predetermined threshold size, it selects one of the preamble sequences in the identified set and sends an access request, using the selected preamble sequence, to a serving eNB via the Random Access Channel.

Abstract: In a 3G cellular network, a Reverse Link Channel Quality Indicator Channel (R-CQICH) may be transmitted on a reverse link to support forward link high-speed data transmissions. Accordingly, the R-CQICH may be utilized to track the quality of the signal path between the wireless unit and the base station. The base station may include a CQI component that utilizes a received Channel Quality Indicator (CQI) signal from the wireless unit to generate CQI quality metrics based on the quality of the received signal. Also, the CQI quality metrics may be compared to different thresholds to adjust various system configurations in the base station. The base station may also provide feedback to the wireless unit with the updated system configurations. This technique allows CQI quality metrics to be utilized to adjust system configurations dynamically and enhance the operation of a wireless system.
