Abstract:
Systems and methodologies are described that facilitate operating an access terminal in an LTE based wireless communication environment utilizing extended microsleep. While in non-DRX mode, an access terminal can operate in on state for a first period of time and in extended microsleep state for a second period of time. Further, the first and second periods of time can form a repeating pattern where these periods of time alternate. Thus, the access terminal can turn on its receiver for the first period of time (e.g., decode downlink information while in on state) and turn off its receiver for the second period of time (e.g., inhibit decoding of downlink information while in extended microsleep state). Further, the first period of time in the repeating pattern can be one TTI (e.g., 1 ms) and the second period of time in the repeating pattern can be a plurality of TTIs (e.g., 5 ms).
Abstract:
Synchronous adaptive HARQ is utilized to mitigate resource fragmentation. Bitmaps are utilized instead of scheduling uplink grants for retransmission. The location of one or more resource blocks can be changed if there is a release of resources in a location of a corresponding resource block. Changing the location of the one or more resource blocks can group the resource blocks toward a first end of a spectrum. The bitmap can include a retransmission offset and a signal that indicates a direction with respect to the retransmission offset. The direction can be a positive direction or a negative direction.
Abstract:
Quality-of-service information provides details related to data packets, including delay information. A data packet header may be analyzed to determine a portion capable of retaining quality-of-service information. Quality-of-service information may be compressed and placed into the identified portion. The header may be transmitted to a base station, where the quality-of-service information is decompressed, read, and modification of operations occurs as a function of the quality-of-service information.
Abstract:
Techniques for transmitting random access signaling for system access are described. In an aspect, random access signaling may be sent based on at least one transmission parameter having different values for different user equipment (UE) classes. At least one parameter value may be determined based on a particular UE class, and the random access signaling may be sent based on the determined parameter value(s). The random access signaling may be a random access preamble, and the at least one transmission parameter may include a target SNR, a backoff time, and/or a power ramp. The random access preamble may then be sent based on a target SNR value, a power ramp value, and/or a backoff time value for the particular UE class. In another aspect, a message for system access may be sent based on a power control correction received in a random access response for the random access preamble.
Abstract:
A control scheme using packet headers allows GSM EDGE Radio Access Network (GERAN) systems to increase spectral efficiency through multiplexing techniques, such as superposition coding, multi-user packet transmission, joint detection, and/or joint decoding. A fast feedback scheme for GERAN allows Voice over Internet Protocol (VoIP) frames to be transmitted over GERAN air interfaces without excessive feedback latency. As a result, Hybrid Automatic Repeat-reQuest (H-ARQ) acknowledgements may be timely provided for end-to-end VoIP calls that traverse GERAN air interfaces. Additionally, Incremental Redundancy H-ARQ and link quality feedback latencies are decreased.
Abstract:
Embodiments disclosed herein address the need in the art for efficient management of grant, acknowledgement, and rate control channels. In one aspect, a list associated with a first station is generated or stored, the list comprising zero or more identifiers, each identifier identifying one of a plurality of second stations for sending a message to the first station. In another aspect, sets of lists for one or more first stations are generated or stored. In yet another aspect, the messages may be acknowledgements, rate control commands, or grants. In yet another aspect, messages comprising one or more identifiers in the list are generated. Various other aspects are also presented. These aspects have the benefit of reduced overhead while managing grant, acknowledgment and rate control messaging for one or more remote stations.
Abstract:
Methods, systems, and devices for wireless communications are described to support inclusion of layer 1 (L1) or layer 2 (L2) cell mobility information within a layer 3 (L3) handover command. A base station may transmit, to the UE, signaling indicating for the UE to perform a measurement on a first set of cells. The UE may perform the measurement on the first set of cells and may transmit, to the base station, an indication associated with the measurement on the first set of cells. In response to the indication, the base station may transmit, to the UE, an L3 handover command, where the L3 handover command may include L1 or L2 cell mobility information, such as an indication of a second set of cells that the UE is to use for L1 or L2 cell mobility after completing the L3 handover command.
Abstract:
Methods, systems, and devices for wireless communications are described. A first device may cooperate with a second device to form a virtual device configured to communicate with a radio access network. The virtual device may appear as a single device from the perspective of the radio access network. Subsequently, a third device may be identified for replacing the second device within the virtual device. Based on the third device being identified, procedures for handing over communications from the second device to the third device may be executed. The procedures may include a beam management procedure, a random-access procedure, a mobility management procedure, or any combination thereof.
Abstract:
Wireless communications systems and methods related to accessing a channel based on an interference condition in a wireless communication network are provided. For example, a method of wireless communication performed by a wireless communications device may include receiving, from a second wireless communication device, one or more signals associated with a beam parameter, determining, at each of a plurality of locations, a signal measurement for at least one received signal of the one or more received signals, and determining, based at least in part on a cumulative distribution of the signal measurements at the plurality of locations and a reference probability distribution, whether the second wireless communication device satisfies an interference condition. Other features are also claimed and described.
Abstract:
Methods, systems, and devices for wireless communications are described. A UE may cooperate with a group of one or more other UEs, where the UEs may each operate as a panel in a wireless communications system. To ensure updated information based on the cooperation status of the UE is provided to a network, the UE may receive one or more capability request messages from a base station. The UE may determine a group cooperation capability of the UE, based on a current group cooperation status of the UE. The group cooperation status may be based on the UE operating in cooperation with a group of UEs for communicating with the base station. The UE may then transmit, to the base station, one or more messages indicating the group cooperation capability of the UE.
