WebFollowing table from 36.213 shows the LCID types of MAC header. The parts marked in red rectangle is LCID representing various MAC CE. These are relatively small set of MAC CE defined in 36.321 Rel 8 - 6.1.3 MAC Control Elements. You will see this gets longer as new release comes out (Refer to LTE-Advanced MAC for the snapshot of the evolution ) WebBSR (Buffer Status Report) This is mainly for Uplink throughput. If network or test equipment is configured to schedule uplink data transmission (PUSCH) based on BSR, network would not allocate large TBS unless UE send BSR with high value. If you need to troubleshoot throughput issues in this case, you need to check all BSR values and see if UE ...

WebIt is 1024 x 10 ms, which is 10240 ms (=10240 subframe = 10.24 sec). Most of timing related parameters (e.g, Idle mode DRX, Connected Mode DRX, BSR Report period etc) are configured within this max timiing value. However, as LTE evolves, especially as LTE tries to cover MTC or IoT related features it turned out that this max time span is not ... WebYou would see that the length of PRACH preamble varies depending on the preamble format. For example, the length of PRACH with preamble format 0 is (3186 + 24567) Samples. (As you know, one sample (Ts) is 1/30.72 (=0.03255) us. It is defined as 1/ (15000 x 2048) seconds (=0.03255 us) in 36.211 4 Frame structure).
WebThere are four LCGs being used in LTE and each of the group has it's own ID from 0 to 3. You can see how this LCG ID is being used in BSR (Buffer Status Report) The LCD is usually used in the DRB settings as shown below. (The most common place for DRB setting is in RRC Connection Reconfiguration message ). WebPUCCH is a Uplink Physical channel that is designed to carries UCI (Uplink Control Information) There are 5 different types of PUCCH defined in 3GPP, PUCCH Format 0,1,2,3,4. Each type is classified in terms of a few factors like the way of physical resource allocation, number of bits it can carries etc. Format 0,1 is to carry the UCI bits <= 2 ...
WebWiFi ShareTechnote WiFi OFDMA OFDMA (Orthogonal Frequency Division Multiple Access) is a new technology introduced from 802.11ax (WiFi 6). It is a technology that enable an WiFi AP to communicate with multiple STA (User) at the same time. The main difference between OFDM and OFDMA can be illustrated as follows. WebApr 2, 2015 · Long BSR is used to report UL buffer for all logical channel groups. So there is no LCG ID (Logical channel id) information in Long BSR. Each Buffer Size field represents one logical channel group. The Buffer Size field itself is 6 bit long. That means only 64 different combination can be possible.
WebProbably the most practical answer they found seems to be the bandwidth of 1RB because 1 RB is the minimum scheduling unit of current (legacy) LTE in frequency domain. They might have tried to pick narrower bandwidth (e.g, 6 subcarriers etc). However, in this case it would require too much redesign from the legacy LTE.
WebLCID (Logical Channel ID) LCID is one of the most important component of a MAC header. Basically it tells the characteristics or the destination of the MAC data. For example, it tells whether the MAC data is for control signal or user data or signaling message etc. For the details, refer to MAC PDU Structure for SCH. how to draw horse eyesWebi) Transmit send a signal to reciever. ii) Reciever measure the power of the signal from the transmitter. iii) if the measured power is too low, the reciever send a special command saying "increase the power". And if the measured power is too strong, it would send another command saying "decrease the power". how to draw horse back legsWebThe TBS (Transport Block Size) calculation is based Qm,R,v and number of REs mentioned in 5G NR 38.214 standard.
