Abstract: A base station generates, e.g., based on current UE and current system information, a UE specific paging priority list for an idle or inactive mode UE identifying a set of (small cell base) stations which are to be used to subsequently page the UE. The base station communicates the paging priority list to the UE in a radio resource control release message. In some embodiments, the release message further conveys information indicating a maximum paging monitoring duration and/or a maximum number of paging cells to be monitored. The UE receives the release message and transitions into idle or inactive mode. The UE uses the communicated information to perform efficient paging, identifying which small cells are potential sources of a paging signal, and determine how long to monitor for a paging signal.

Abstract: According to one configuration, a system includes user equipment in communication with a wireless base station. The user equipment receives a notification from a first wireless access point of multiple wireless access points. The notification indicates a set of candidate wireless access points in the wireless network environment in which to selectively perform a handoff from a first wireless access point. The user equipment monitors for occurrence of a trigger condition. In response to detecting a trigger condition, the user equipment identifies (such as selects) a second wireless access point (from the set of candidate wireless access points) in which to perform the handoff. Via communications from the user equipment to the second wireless access point, the user equipment initiates the handoff. The user equipment notifies the first wireless access point of the attempted and/or failed attempt of the handoff to the second wireless access point.

Abstract: A first communications device including a transmitter, such as a base station or UE, identifies a first packet flow for which end to end packet retransmission is supported. The first communications device assigns said first packet flow to a Hybrid Automatic Repeat Request (HARQ) process which does not require generation of acknowledgements (ACKs) or negative acknowledgements (NAKs) from a device receiving data corresponding to said first packet flow; and transmits data corresponding to said first packet flow to a second communications device. In some embodiments, the HARQ process to which the first packet flow is assigned is a dedicated HARQ suppression process. In some embodiments, the HARQ process to which the first packet flow is assigned is a HARQ process which has been temporarily designated as a HARQ suppression process. HARQ suppression is applied for the first packet flow at a radio link layer and/or MAC layer.

Abstract: One or more shared data channels, e.g., PDSCH, PUSCH, PSSCH, are configured to be DMRS-free, thus allowing the resources which would be used for DMRS to be used to convey additional traffic data signals. Channel estimation based on control channel DMRS, e.g., PDCCH DMRS, PUCCH DMRS, or PSSCH/PSCCH DMRS, is used to demodulate and/or decode the traffic channel signals communicated on the DMRS-free shared traffic channel resources. Antenna port hopping is implemented as part of the PDCCH configuration to support a DMRS-free PDSCH. The antenna port hopping of the PDCCH is used to obtain a set of channel estimates based on PDDCH DMRS corresponding to different antenna ports which will match the antenna ports used for the PDSCH.

Abstract: A master node (MN) communicating with a UE using resource of a first band of unlicensed spectrum sends an addition request to a selected secondary node, to request resources for supporting the UE in a second band of unlicensed spectrum. The addition request includes minimum frequency separation information and optionally a baseline reference frequency. The minimum frequency separation information communicated in the addition request, indicates a minimum amount of frequency separation to be maintained between the communication resources in the first band of unlicensed spectrum used for communications with the UE and communication resource in the second band of unlicensed spectrum to be used for communications with the UE. The secondary node selects a channel within the second band of unlicensed spectrum to use for communications with the UE, which will satisfy the minimum frequency separation requirement communicated in the addition request and avoid IDC problems for the UE.

Abstract: According to one configuration, a system includes a mobile communication device in communication with a wireless base station. During operation, the mobile communication device detects one or more conditions associated with the wireless network environment. Based on the one or more detected conditions, the mobile communication device selects amongst multiple channel access procedures to communicate with the wireless base station and establish a wireless communication link. The mobile communication device can be configured to include supplemental data in a message to the wireless base station to indicate a reason for the mobile communication device selecting a particular channel access procedure of the multiple channel access procedures.

Abstract: Methods and apparatus for managing system information message transmission in a distribution network (e.g., a wireless network such as one compliant with 3GPP 5G NR-U). In one embodiment, transmission of multiple SI (System Information) messages with overlapping SI-windows is enabled but with no soft-combining support. In another embodiment, transmission of multiple SI-messages with overlapping SI-windows is enabled with soft-combining support. In yet another embodiment, aperiodic OSI transmission is enabled. Moreover, the present disclosure provides mechanisms for notifying UE of an SI change.

Abstract: Apparatus and methods for improving coverage and/or power-saving in a wireless network. In one embodiment, the apparatus and methods provide mechanisms for wireless user device (such as e.g., a 3GPP-compliant UE) to utilize downlink transmissions related to a first access technology (e.g., LTE) to enhance the detection and reception of downlink transmissions from a second access technology (e.g., 5G NR). In one variant, transmissions relating both access technologies are multiplexed on a shared frequency channel; a UE trying to detect 5G NR transmissions from a gNB leverages the easier detection of certain LTE signals such as PSS to enhance detection of the 5G NR signals. Moreover, the location of the LTE PSS (or SSS) can be used to indirectly assist a UE with detection of the NR SSB, such as via reduction of the number of noise-only samples passed to the NR PSS/SSS autocorrelation detector.

Abstract: A communication management resource implements an iterative process to derive settings for digital precoder W, analog precoder A, and decode function D with a bandwidth-limited fronthaul link between the application of digital precoder W and the application of analog precoder A. The iterative process includes: for a first instance of digital precoder W and decode function D, optimize an instance of the analog precoder A; and based on the optimized instance of the analog precoder A, optimize a second instance of the digital precoder W and the decode function D. In one implementation, for each iteration of multiple iterations, the communication management resource: i) optimizes an instance of the analog precoder A based on an instance of the digital precoder W and the decode function D, and ii) optimizes an instance of the digital precoder W and the decode function D based on the instance of the analog precoder A.
