  • Patent number: 11758615
    Abstract: Embodiments of a User Equipment (UE), Evolved Node-B (eNB) and methods for communication in accordance with a packet convergence and link control (PCLC) layer are generally described herein. The UE may receive, from a Fifth Generation (5G) eNB, a first group of medium access control (MAC) protocol data units (PDUs) that include PCLC PDUs. In accordance with PCLC sequence numbers (SNs), the UE may reorder the PCLC PDUs and may decipher the PCLC PDUs. The UE may receive, from a legacy eNB, a second group of MAC PDUs that include packet data convergence protocol (PDCP) PDUs encapsulated in radio link control (RLC) PDUs. The UE may reorder the RLC PDUs based on RLC SNs and may decipher the RLC PDUs based on PDCP SNs that are exclusive to the RLC SNs.

  • Patent number: 11595950
    Abstract: To effectively and efficiently provide control information, a broadcast pointer channel (BPCH) may be used to identify the type and perhaps relative location of control information that is being provided in a given frame structure, such as a sub-frame, frame, or superframe. A sub-frame (or like framing entity, such a frame or superframe) may have a BPCH and a corresponding system control information segment in which control information may reside. The system control information segment may have any number of control information blocks, wherein each control information block that is present may correspond to a particular type of control information. The BPCH is used to identify the type of control information that is present in a corresponding system control information segment, and if needed or desired, the relative locations of the various control information.

  • Patent number: 11581990
    Abstract: Disclosed herein are apparatuses, systems, and methods using or implementing dynamic resource allocation (DRA) of resources for machine-type communication (MTC), as a secondary partition within a system bandwidth. Allocations outside the secondary partition are configured as a primary partition for other than MTC. Apparatuses may perform MTC communications within the secondary partition when DRA configuration information includes allocation information for the secondary partition and the apparatus is configured for MTC. Otherwise, if the apparatus is other than MTC, the apparatus may refrain from performing communications in the secondary partition. Other embodiments are described.

  • Patent number: 11515969
    Abstract: Methods described herein are for wireless communication systems. One aspect of the invention is directed to a method for a HARQ process, in which the HARQ process includes a first transmission of an encoder packet and at least one retransmission. The method involves allocating a transmission resource for each respective transmission. The method involves transmitting control information from a base station to a mobile station for each respective transmission. The control information includes information to uniquely identify the HARQ process and an identification of one of a time resource, a frequency resource and a time and frequency resource that is allocated for the transmission. In some embodiments of the invention, specific control information is signalled from a base station to a mobile station to enable RAS-HARQ operation. In some embodiments of the invention, retransmission signaling in included as part of regular unicast signaling used for both first transmission and retransmissions.

  • Patent number: 11509431
    Abstract: Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.
