2、mpanies to advance the industrys most pressing business priorities. ATIS nearly 200 member companies are currently working to address the All-IP transition, network functions virtualization, big data analytics, cloud services, device solutions, emergency services, M2M, cyber security, network evolut

3、ion, quality of service, billing support, operations, and much more. These priorities follow a fast-track development lifecycle from design and innovation through standards, specifications, requirements, business use cases, software toolkits, open source solutions, and interoperability testing. ATIS

Notice of Disclaimer the description in the time domain is addressed in subclause 4.5. 4.2 Bursts 4.2.1 General A burst is a period of RF carrier, which i

The physical channels where the TDMA frame number sequence is 0,1. . FN_MAX (where FN_MAX is defined in subclause 3.3.3) are called basic wideband

7、 physical channels. 4.6 Parameters for Channel Definition ii) The TN; iii) The MA; iv) The type of logical channel. ATIS-0700361 10 5 Mapping of Logical Channels onto Physical Channels 5.1 General The detailed mapping of logical channels onto physical channels is defined in the following subclauses.

8、 Subclause 5.2 defines the mapping from TDMA FN to RFCH. Subclause 5.3 defines the mapping of the physical channel onto TDMA frame number. 5.2 Mapping in Frequency of Logical Channels onto Physical Channels 5.2.1 General The parameters used in the function which maps TDMA frame number onto radio fre

9、quency channel are defined in subclause 5.2.2. 5.2.2 Parameters The following parameters are required in the mapping from TDMA frame number to radio frequency channel for a given assigned channel. General parameters of the BTS, specific to one BTS, and broadcast in the broadcast channel and WSCH: i)

10、 CA: Cell allocation of radio frequency channels. ii) FN: TDMA frame number, broadcast in the WSCH, in form T1, T2, T3. Specific parameters of the channel, defined in the channel assignment message: i) MA: Mobile allocation of radio frequency channels, defines the radio frequency channel. 5.3 Mappin

11、g in Time of Logical Packet Channels onto Physical Channels 5.3.1 General A physical channel allocated to carry packet logical channels is called a packet switched channel (PDCH). A PDCH shall carry packet logical channels only. Packet switched logical channels are mapped dynamically onto a 52-multi

12、frame. The 52-multiframe consists of 12 blocks of 4 consecutive frames and 4 idle frames. A block allocated to a given logical channel comprises of one radio block. The type of channel may vary on a block by block basis. Table 5.1 below indicates the frame numbers for each of the blocks (B0.B11) tra

13、nsmitted in the multiframe. In case of wideband long bursts with channel coding WGPRS Modulation and Coding Scheme (WMCS)-2 and WMCS-4 one burst forms one radio block, and each frame can be referred to as a subblock of the bigger block (B0.0, B0.1, B0.2, B0.3, B1.0, B1.1 B11.3). In the downlink dire

14、ction, the logical channel type shall be indicated by the message type contained in the block header part. The frequency correction channel and synchronization channel will be always transmitted after each other. Transmission takes place twice during each idle frame. First pair of bursts is sent in

15、time slots 0 and 1, the second pair on time slots 32 and 33.
