On the capacity of a UTRA-TDD network with multiple services

Radio resource management for downlink multimedia services in TDMA/CDMA interference-limited cellular networks

“…The self-corrective measure proposed employs transmission power requirement available through the power control routine as an index of the session's interference state. This is superior in terms of signaling cost and reliability to other adaptive schemes that rely on the receiver reporting its BER state or asking for a resource re-assignment when packet loss occurs [11,12]. To address the limitations of the distributed MIP, we propose the minimum sum of path-loss ratios (MS-PLR) algorithm [18].…”

“…Unfortunately, the identity of interferers has a significant importance on the performance of various sessions. Hence, numerous measurement-aided schemes have been proposed that select timeslots with favorable SINR performance, such as, [9][10][11][12]. The least interfered resource (LIR) algorithm presented in [11], and [12] is shown to provide the best performance among those, where LIR selects the least interfered timeslot for assignment.…”

“…Such approach achieves statistical multiplexing with moderate signaling cost as compared to framedriven assignment, where timeslot decisions are computed each TDMA frame. We argue that packet-bypacket scheduling often assumed in the literature [12,19] investigating data traffic is not really necessary due to the low duty cycle characterizing WWW browsing traffic [20]. We will show that when simple FCFS scheduling is used, the channel access delay is negligible due to low probability of simultaneous page download requests.…”

Analysis of the Percentage of Outage for Multimedia Services in Cellular Networks

“…Studies employing the satisfied-user criteria in investigating cellular networks have been mainly limited to simulations, such as [3]- [5]. Outage percentage of speech and WWW browsing sessions has not been well analyzed.…”

Performance of dynamic timeslot-code assignment strategies in UTRA-TDD

“…For speech services TCA operates in a burstdriven manner where the TCA assigns resource to traffic sources only during activity periods. This is shown to enhance system capacity over circuit-switched allocation proposed for other investigations addressing UTRA-TDD [3], [4]. TCA for video streaming services is applied periodically to ensure maintaining session quality during the connection interval.…”
