Abstract: Facilitating a group hybrid automatic repeat request procedure for sidelink group-case in advanced networks (e.g., 4G, 5G, 6G, and beyond) is provided herein. Operations of a method can comprise determining, by a first device comprising a processor, that first information received via a sidelink control channel is successfully decoded and that second information received via a sidelink shared channel is not successfully decoded. The first information and the second information can be received from a second device. Further, the method can comprise transmitting, by the first device, negative acknowledgement data based on a group hybrid automatic repeat request feedback procedure. The method also can comprise receiving, by the first device, retransmission of the second information via the sidelink shared channel from a group of devices in response to the negative acknowledgement data.

Abstract: The disclosed technology is directed towards switching the primary cell in a carrier aggregation scenario to improve performance. Measurement data of a mobile device (user equipment) is evaluated with respect to one or more various criteria such as cell carrier bandwidth, cell carrier load, cell-related capability and other carrier data (e.g., dynamic spectrum sharing versus clean, time division duplex or frequency division duplex), and others. Device conditions such as overheating can be considered as well. The evaluation results in a ranking of primary cell candidates. If a more optimal primary cell (candidate) is available, the primary cell in the carrier aggregation combination is switched to the candidate that is ranked the highest. Switching can be relatively very fast, such as based on already existing layer-1 (L1) and/or layer-2 (L2) measurement data. Layer-3 (L3) measurement data also can be obtained on demand, for example, to use in the evaluation.

Abstract: The technologies described herein are generally directed to using a reflective surface to reflect a signal from access point equipment to signal receiving equipment in a fifth generation (5G) network or other next generation networks. For example, a method described herein can include receiving a request from access point equipment to establish a communications session between the access point equipment and a user equipment. The method can further include identifying a reflective surface to facilitate a connection between the user equipment and the access point equipment, resulting in reflected path information corresponding to a reflected path for the communications session. Finally, the method can include, in response to the request, communicating to the access point equipment, the reflected path information.

Abstract: The technologies described herein are generally directed to detecting reflective surfaces for use reflecting a signal from access point equipment to destination equipment in advanced networks, e.g., at least a fifth generation (5G) network. For example, a method described herein can include receiving a request, from access point equipment, to establish a communications session between the access point equipment and destination equipment. The method can further include identifying a mobile reflective surface to reflect a communications beam to facilitate a connection between the destination equipment and the access point equipment, resulting in reflected path information corresponding to a reflected path for the communications session. Further, the method can include, in response to the request, communicating to the access point equipment, the reflected path information.

Abstract: Aspects of the subject disclosure may include, for example, obtaining first positional information comprising a location of a non-stationary entity mobile within an environment, the first positional information obtained from a service provider monitoring a positional status of the non-stationary entity within the environment. A path of the non-stationary entity is predicted according to the first positional information. A delivery device mobile within the environment is directed according to the predicted path to deliver an item to the non-stationary entity. Second positional information is obtained, identifying a location of the delivery device within the environment. A separation distance is calculated between the location of the non-stationary entity and the location of the delivery device within the environment and a delivery opportunity is detected based upon the separation distance not exceeding a threshold distance. Other embodiments are disclosed.
