So, the companies having concern on the scenario would like to have a UE capability to report whether UE supporting Rel-18 UL Tx switching with 3 or 4 bands can fallback to 1T-1T UL Tx switching between 2 bands or not. The UE uses a Proximity Indication message to specify the RF carrier belonging to the CSG cell and also to specify whether the UE is entering or leaving the coverage area. These categories help in defining the maximum data rates, supported bandwidths, and other key parameters for a particular device. Dec 5, 2020 · Additionally, if the UE changes its radio capabilities, it will initiate a Tracking Area Updating procedure and include the IE UE radio capability information update needed in the TAU REQUEST message. It will define the proper carrier aggregation configuration set to be used. Otherwise, UE wouldn't be able to process the SCell configuration from the network and abnormal things will happen. The physical implications of increasing the number of receive antennas are twofold. On the other hand, they will introduce additional power back-off for the power Nov 14, 2012 · However, even if carrier aggregation in the uplink is defined with Rel-10, it is most likely that initial LTE-Advanced deployments for FDD make use of carrier aggregation only in the downlink. If the total eNB scheduling for DL-SCH and an MCH in one serving cell at a given TTI is larger than the defined processing capability, the prioritization between DL-SCH and MCH is left up to UE In uplink CA or SUL, a UE configured with uplink Tx switching can have Tx chain(s) dynamically switched from one uplink band or two uplink bands to another uplink band or two uplink bands for enabling up to 2Tx UL transmission in one uplink band or simultaneous UL transmissions in two uplink bands at a time. 133 [13].

May 9, 2023 · This simulation is based on 4cc, FDD and TDD, 15-60 MHz bandwidth, a mix of 1-2cc UE Carrier Aggregation capability and typical MBB traffic model * Expressed as how many more users can be served with maintained 5th percentile (=5% worst) user throughput ** Advanced MLC takes cell load into consideration Methods, systems, and devices for wireless communication are described. S. In the NR specification, each component carrier appears as a separate “cell,” and a carrier aggregation capable UE is said to be able to communicate with multiple cells. UE Assistance Information is a special RRC message (mechanism) by which UE can inform various internal status to the network so that Network can assign / control resources better fit for the specific moment of each connected UE. During Lte Registration procedure, UE reports detailed Carrier Aggregation (CA) capability in UECapabilityInfomration Message. With carrier aggregation, it is possible to schedule a user equipment (UE) on multiple component carriers simultaneously. Jan 1, 2022 · The terminal supports UE capability 1 by default to meet conventional delay requirements, while UE capability 2 needs to be reported to meet ultralow delay requirements. . Actually this is not a new concept in LTE. On each Jun 7, 2017 · Carrier Aggregation in LTE-A (LTE Advanced) Carrier Aggregation (CA) is a key technology in 4G LTE Advanced (LTE-A) to enable higher capacities on mobile networks. carrier aggregation mainstream, with global proliferation, which benefits the entire mobile ecosystem: Operators, App developers, and OEMs – by delivering higher data rates, improved capacity, and the ability to use spectrum Proximity detection allows the UEs to inform the eNodeB when it enters or leaves the coverage of a CSG cell included within its whitelist. 0 (2019-04) Intellectual Property Rights Essential patents IPRs essential or potentially essential to normative deliverables may have been declared to ETSI. The basic concept of carrier aggregation and the process of establishing carrier aggregaion in NR is almost same as LTE carrier aggregation. 101-2 which are specifically for FR1 and FR2 User Equipment (UE) radio transmission and reception, the allowed operating bands for intra-band, inter-band, carrier aggregation are completely listed. As shown above, there are two tables of N1 value. 306 v15. Following is overall steps for LTE adavanced Carrier Aggregation and UE Capability Information and RRC Connection Reconfiguration is the critical steps for Carrier Aggregation configuration. k. 6 Other Physical Layer and MAC Procedures • 1. Sep 5, 2013 · The indicated number of layers for spatial multiplexing may exceed the number of layers required according to the category indicated by the UE. , n1 —2. Here the carriers are adjacent to each other. Keywords: Supplementary uplink Uplink enhancement Carrier aggregation 1 Introduction In the 4G era, the network capability is mainly for consumers, and the downlink traffic is mainly used. This information is crucial for determining which frequency bands can be used for the 5G NR connection in NSA mode. Jul 6, 2023 · SEOUL, Korea – July, 6, 2023 — Samsung Electronics Co. Once the UE acquires the serving cell and reads the SystemInformationBlocks, it becomes aware of the cell HPUE capability by reading the subframe configuration and P-MAX value. The many carriers are controlled by a single access point (in Wi-Fi) or base station (in cellular systems). Carrier Aggregation • 1. Page What is Carrier Aggregation? •Combining (using) multiple LTE carriers together in order to increase data throughput •Extends the maximum transmission bandwidth, up to 100 MHz, by aggregating up to five LTE carriers – a. New radio (NR) positioning in the Third Generation Partnership Project (3GPP) Release 18 (Rel-18) enables 5G-advanced networks to achieve ultra-high accuracy positioning without dependence on global navigation satellite systems (GNSS) with key enablers such as the carrier phase positioning technique, standardized for the first time in a cellular communications standard and setting a It is presented a method for obtaining a capability of channel spacing between component carriers used in carrier aggregation for a user equipment, UE. 138-147. By providing a UE with the PRU’s RSCPD measurements, along with associated times-tamps, the UE can compute a double differential measurement, effectively canceling out the Tx phase biases. UE Assistance Information. These tests cover the follo wing broad areas: • Basic Carrier Aggregation Configuration and Activation Functionality • Connected Mode Mobility in Carrier Aggregation Enabled Cells Jul 18, 2014 · LTE-A Carrier Aggregation. Intra-band contiguous carrier aggregation. LTE1092: Uplink Carrier Aggregation – 2CC can coexist with up to 4CC DL CA; however, to enable DL+UL CA, the existing SCells need to be reconfigured either to 3CC DL + 2CC UL or 2CC DL + 2CC UL. A User Equipment (UE) may transmit a capability message indicating that the UE supports operation in an enhanced uplink carrier aggregation mode for transmission of a first uplink message on a first component carrier that overlaps in time with transmission of a second uplink message on a second component carrier. a component carriers (CCs) •Initially defined in the 3GPP Release 10 standard •To preserve compatibility with existing devices, all aggregated carriers look Apr 21, 2014 · To configure Carrier Aggregation, Network send Secondary Cell (SCell) configuration to only those UEs which are release 10 and support Carrier Aggregation. 10 of 38. carrier aggregation mainstream, with global proliferation, which benefits the entire mobile ecosystem: Operators, App developers, and OEMs – by delivering higher data rates, improved capacity, and the ability to use spectrum fragments. In addition to the traditional large downlink Uplink carrier aggregation schemes beyond 2x100 MHz (2CC) will result in even higher uplink data speeds. Depending on UE capabilities, Secondary Cells (SCells) can be configured to form together with the PCell a set of serving cells. Since it is important to keep backward compatibility with R8 and R9 UEs the aggregation is based on R8/R9 carriers. 7 RRC Procedures Carrier Aggregation . Carrier Aggregation and Component Carriers. Carrier Aggregation Configuration Summary Table. Another method to avoid cross-band interference is to design the bands combinations used for carrier aggregation in a careful way. , Ltd. 38. , which eventually will improve video streaming and extended reality experiences.
