Abstract: Aspects of selecting a base station or coverage area for a UE device are described. The UE device or a wireless network component (e.g., a base station) can determine RF uplink use values of a coverage area sector or cell. The RF uplink use values can be received from one or more base stations and can be based on a subframe or other time segment. The UE device can determine an average and variation of the RF uplink use values, and a load metric. The load metric can indicate a load pattern of an RF uplink. A selection of the base station or coverage area can be based on the load metric and whether the UE device is located or operating at an edge of a cell or coverage area. The UE device, while idle, can continue or switch to camping on the selected base station or coverage area.

Abstract: Disclosed is a system and method for multiple wireless communication devices (WCDs) to share a resource block in an orthogonal frequency division multiplexing communication system by assigning each WCD a different one of multiple different sub-segments of the resource block. A base station can allocate the shared resource block on to the WCDs, and use hash function applied to each WCD to assign a different one of the sub-segments to each WCD. Each of the WCDs can apply the same hash function to determine the same sub-segment assignment made by the base station. For downlink communications, the base station can transmit data to each WCD in the assigned sub-segment, and each WCD can recover its data from its assigned sub-segment. For uplink communications, each WCD can transmit its data to the base station in its assigned sub-segment, and the base station can recover each WCD's data from the assigned sub-segment.

Abstract: Methods and systems are provided for calculating a bias value based on radio frequency signal power measurements. A wireless communication device (WCD) measures the powers of radio frequency signals received by the WCD, including a first radio frequency signal transmitted by a first base station of a wireless network and a second radio frequency signal transmitted by a second base station of the wireless network. The first base station transmits radio frequency signals at a higher power than the second base station. The WCD calculates a bias value based on at least one of the measured powers of the first radio frequency signal and the second radio frequency signal. The bias value, in combination with the measured powers of the first and second radio frequency signals, can be used to select one of the first and second base stations.

Abstract: A method and system for using a positioning reference signal (PRS) of a cell to indicate an operational state of the cell. The cell could have two or more candidate PRS configurations defining physical configurations of its PRS, such as frequency positions of air interface resources that carry the cell's PRS. One such PRS configuration could correspond with one operational state of the cell (e.g., heavy cell load), and another such PRS configuration could correspond with a different operational state of the cell (e.g., normal or light cell load). A base station could thus select and apply a particular PRS configuration to indicate operational state of the cell. And an entity such as a wireless client device or neighboring base station could determine the PRS configuration used in the cell as a way to determine the operational state of the cell.

Abstract: In an example method, a UE receives modulated data transmitted from a base station in a given subframe, and searches through the received modulated data to find the physical control format indicator channel (PCFICH) of the given subframe. The searching is based on the PCFICH having a predefined structure. Upon thereby finding the PCFICH of the given subframe, the UE determines the control format indicator (CFI) carried by the PCFICH of the given subframe. The UE then uses the CFI carried by the PCFICH of the given subframe as a basis to read a portion of a downlink control channel of the given subframe.

Abstract: Disclosed is a method and apparatus to help manage data communication in a manner that increases downlink capacity. As disclosed, a base station may transmit, in a downlink traffic channel of a given sub-frame, bearer data to a particular wireless communication device (WCD). After transmitting the bearer data, the base station may transmit, in the downlink control channel of another sub-frame, a signaling message that directs the particular WCD to read the previously transmitted bearer data. The signaling message may include an indication of the given sub-frame having the previously transmitted bearer data. When the WCD receives and reads the signaling message, the WCD may use the indication as a basis to read the previously transmitted bearer data in accordance with the signaling message.

Abstract: Disclosed is a method and system for management of control channel capacity to help reduce control channel congestion over time. As disclosed, a first base station provides a first downlink control channel including a first set of air interface resources and a second base station provides a second downlink control channel including a second set of air interface resources, the first set of air interface resources and the second set of air interface resources being mutually exclusive. Upon making a determination that the first downlink control channel is threshold loaded (i.e., congested), temporary reconfiguration of the wireless communication system is carried out by transferring a portion of the second set of air interface resources from the second downlink control channel to the first downlink control channel such that (i) capacity of the first downlink control channel is increased and (ii) capacity of the second downlink control channel is commensurately decreased.

Abstract: Disclosed is a method and system in which a PDSCH segment assigned to a UE in a particular TTI not only carries data to the UE but also carries an assignment to the UE of a PDSCH in a subsequent TTI for carrying additional data to the UE in that subsequent TTI. Such an arrangement can help make good use of possibly otherwise unused PDSCH capacity and can help to manage PDCCH capacity in the subsequent TTI.

Abstract: Disclosed is a method and apparatus to help manage communication on a wireless channel when transmitting and receiving nodes will engage in a sequence of data-ACK exchanges with each other on the channel. As disclosed, the transmitting node and/or receiving node may include in at least one of the data-ACK exchanges an indication of how many data-ACK exchanges remain in the sequence and may further include indicia of how often each data-ACK exchange will occur and how long each data-ACK exchange will last. A neighboring node that is observing the channel to determine whether the channel is available may thus determine, based at least in part on the indication in the data-ACK exchange how many times to refrain from transmitting on the channel, how often to so refrain, and how long to refrain in each instance.
