he cell divided by the total number of users in the cell. Let Nu denote the number of users in the sector/cell and assume user k, k = 1, 2, , Nu has a throughput of RDL(UL), , then DL (or UL) sector throughput is defined as: (12-3) The user throughput per transmission is the number of correctly received bits per packet divided by the duration of the transmission. If user k has Pk DL(UL) downlink (uplink) transmissions, if there are DL(UL) packets in the ith transmission, and if there are bik correctly received bits in the jth packet, then the average transmission throughput can be defined as follows: (12-4) where ATDL(UL) denotes the duration of the ith transmission to user k. The average user throughput per transmission is defined as the sum of the user throughputs per transmission divided by the number of users in the cell. The outage throughput Noutage(Rmin) is defined as the percentage of users with data rate RDL less than a predefined minimum data rate Rmin. The cell edge user throughput is defined as the 5th percentile point of the CDF of users' average throughput per transmission, assuming that 95% of the users are expected to achieve a certain throughput per transmission regardless of their geographical location in the cell. If the jth packet of the ith transmission belongs to user k, and if the packet arrives at the BS (or MS) MAC at time instant Tkij arrival and is delivered to the MS (or BS) MAC at time instant departure' then the packet delay can be calculated as follows: (12-5) The downlink and uplink delays are denoted by superscript "DL" or "UL," respectively. The packets that are dropped or erased may not be included in the analysis of packet delays, depending on the traffic model. For example, in the modeling of traffic for delay-sensitive applications, packets may be 12.1 Definition of the performance metrics dropped if packet transmissions are not completed within a specified delay bound. The impact of the dropped packets is included in the packet loss rate. The CDF of the packet delay per user
