, then the payload length of the DCI0 Bitstream is (1+1+11+5+1+2+3+2+1) = 27, so l_format=27,n=13. Because 13 (Fig. 1) (Figure 2 Table to look for when adjusting Pusch power) (Figure 3 The table to look for when adjusting the PUCCH power) 2.UE How to determine whether the current pucch adjustment or Pusch adjustment Since DCI3 can adjust the power of Pusch, can also adjust the power of the PUCCH, then how to differentiate the UE? Here the protocol uses different Rnti values to differentiate.

1, ENB antenna arrival angle (LTESCAOA) beyond the normal rangeIn the OMC-R measurement reporting technical requirements, this field is defined as:"Defines the estimated angle of a user's relative reference direction. The measurement reference direction should be true north, counterclockwise. can assist to determine the location of the user, providing location services, accuracy of 5 degrees. This measurement data represents the number of samples that meet the range of criteria in the omc-r stat

Users may need to add their own configurations in the following ways: Directly configured in the base station RRC entity; Configure the existing switching algorithm; A new switching algorithm is develo

In view of the previous day to write a relevant knowledge point, and occasionally due to work reasons, did not follow up every day, so decided to write today another on the key technology of LTE knowledge, but also the last son.SON: (self organized network) ad-organized networks ;Contains three aspects: self-configuring, ANR (Automatic neighborhood optimization), MRO (switching self-optimizing);Automatic configuration is the base station cell equipmen

Since 2008, Red Bend has partnered with Alcatel-Lucent to help device manufacturers and mobile network operators deliver mobile devices and services to the market faster and more easily. Using the OMA DM client on 4G LTE devices, device manufacturers can ensure that their devices are seamlessly compatible with the operator's Custom open Mobile Alliance Device Management (OMA DM) specification. "Industry standards like OMA DM enable mobile operators to

Summary: Core platform of 3GPP, http://www.3gpp.org/ftp/Specs/html-info/23228.htm First released by 3GPP Release 5, in order to enhance packet-switched domain (UMTS) in supporting IP multimedia services. Providing back compatibility to circuit-switched domains and functionality to other IMs domains. Nowadays, IMS provides access to Internet services (e.g. email, VoIP, video, etc) overdifferent networks (3g, cable TV, WLAN, XDSL, LTE, etc ). the

Once the security mode is activated, all RRC messages (including some NAS or 3GPP messages) of srb1 and srb2 are protected and encrypted through PDCP, NAS only protects and encrypts the integrity of NAS messages. In other words, layer-2 encryption and Protection of LTE: NAS only performs control signaling encryption, while PDCP performs both contr
