“…present or absent) during each PO [7,9]. If the paging message is present, the UE will perform the following operations: Multiple SSBs measurements, light sleep levels, Physical Downlink Control Channel (PDCCH) monitoring and Physical Downlink Shared Channel (PDSCH) decoding [7,9,10]. Otherwise, if the paging message is absent, the UE doesn't need to perform anyone of the previous operations.…”

Energy consumption is one of the most important challenges in Millimeter Wave (mmWave) 5G wireless communications since higher data rate and lower latency are required. Thus, User Equipment (UE) battery suffers from its energy absorption. To investigate a green communication, Discontinuous Reception (DRX) mode is introduced when no traffic arrival from the Base Station (BS) to extend UE battery lifetime but delay is increased. This paper introduces an advanced DRX, which can achieve extended UE battery lifetime with a reasonable reduced delay due to a proposed sub-frame size. Generally, traffic which arrives may be data packet or paging message. This paper evaluates two proposed system models based on traffic which arrives during wake up periods of the UE. The first system model is called Signaling Based DRX and the second system model is called Enhanced Paging Monitoring (EPM). The both system models utilize two different indicators; they are Power Saving Indicator (PSI) and Paging Early Indicator (PEI), respectively. These indicators enhance power saving and delay compared to that of the traditional approach. The evaluation of the both system models performance is by measuring the power saving factor and the average delay of the UE over the same data/paging traffic arrival rate. A MATLAB simulation program is used to validate the system model and the numerical analysis. Analytical and numerical results are considered.

“…wireless systems identifies the individual user equipment (UE) nodes to the corresponding base station via wireless transmissions [10], [11], [12], [13], [14]. Conventionally, the identification information is transmitted via communication channels from a source, e.g., smart label or UE, to a sink, e.g., warehouse controller or base station, based on Shannon's principles of message transmission (communication via channels).…”

Identification Codes: A Topical Review With Design Guidelines for Practical Systems

et al. 2023

A wide range of information technology applications require the identification of a particular message or label that represents the identity of an object at a distance, e.g., over a wireless channel. Conventionally, the underlying information that represents the identity is transmitted over the channel, following the information-theoretic concept of message transmission. If the purpose of the interaction over the channel is only to verify (match) an identity, then the concept of identification over channels-utilizing the identification codes that have been developed by the information theory community-can provide an exponential efficiency gain over message transmission. This topical review article conducts for the first time a comprehensive detailed evaluation of the existing identification codes for the practically relevant regime of finite parameters. We examine essentially all published identification codes, including codes based on inner constant weight codes that are concatenated with outer linear block codes, such as Reed-Solomon and Reed-Muller codes. Specifically, we conduct a holistic identification code comparison based on the logarithm of the number of representable identities (in shannon), the size (in bit) of the transmitted cue that represents an identity, and the corresponding type II error probability bound for essentially all existing identification codes. Based on the resulting insights, we formulate guidelines for the design of practical (finite-parameter) identification codes. For instance, we find that a linear block code (without concatenation with a sophisticated inner constant-weight code) is sufficient for most practical identification code usages.

“…The efficient DRX cycle schemes, such as Enhanced Paging Monitoring (EPM) and Extended Discontinuous Reception (eDRX), aim to minimize radio resource overhead in the 5G [3]- [5]. In addition, a beam-aware DRX scheme [6] and Partitioned UE ID-based Directional Paging (PIDP) [7] are applied to alleviate the computational burden of beam search in the 5G.…”

5G adopts Discontinuous Reception (DRX) technology, which enables the User Equipment (UE) to repeat sleep and wake-up cycles for power-saving. To minimize power consumption, the UE needs to re-synchronize to a downlink signal transmitted from a serving gNodeB (gNB) for each DRX occasion.To have a synchronization technique suitable to DRX occasions, we design and implement a history-based synchronization scheme that can effectively manage the window of synchronization signal detection. The proposed scheme primarily considers the statistics of previously detected timing offsets when configuring the window of synchronization. The history information is formatted appropriately for calculating the drift of the timing offset on each DRX occasion. The proposed scheme also monitors multi-path environments and extends the detection window to the timing offset of the second path based on the probabilistic model. To demonstrate its performance, the proposed scheme is implemented on a software modem so that it can be processed in real-time. The experimental results demonstrate that the proposed scheme can reduce computational complexity and achieve more precise synchronization in a low Signal to Noise Ratio (SNR) regime.
