Abstract: According to aspects of the disclosure, a method and system are provided for managing cell selection in a wireless communication network. In accordance with this disclosure, each cell in a radio access network (RAN) broadcasts a respective carrier-aggregation policy of the cell on its air interface. A UE engaging in a cell selection process reads the respective carrier-aggregation policy of each cell under consideration and selects a cell on which to attach based at least in part on the respective carrier-aggregation policies of the cells. The UE can then attach to the selected cell so that the selected cell can then serve the UE.

Abstract: A method for controlling a UE situated in both a coverage area of a first base station and a coverage area of a second base station involves detecting that the UE is ping-ponging between being served by the first base station and being served by the second base station and determining that the second base station is a relay base station. Further, the method involves, responsive to detecting the ping-ponging and determining that the second base station is a relay base station, (a) determining a carrier on which the first base station provides service and on which the second base station does not provide service, and (b) based on the first base station providing service on the determined carrier and the second base station not providing service on the determined carrier, causing the UE to be served by the first base station on the determined carrier.

Abstract: A method for controlling tune-away of a UE from its serving base station during handover, where the UE is configured to tune away from its serving base station at scheduled tune-away times, is disclosed herein. The method includes, between a first scheduled tune-away time and a next, second scheduled tune-away time, (a) determining that the UE has threshold weak signal strength from the serving base station, and (b) responsive to determining that the UE has threshold weak signal strength from the serving base station, determining a remaining battery energy level of the UE. The method further includes, based at least in part on the determined remaining battery energy level of the UE, causing the UE to tune away from the serving base station before the second scheduled tune-away time to scan for target coverage.

Abstract: As disclosed, while a wireless communication device (WCD) is idling on a particular carrier frequency of a base station, the base station may receive a message broadcast by that base station, the message specifying multiple relative sets of priority levels defined for a set of carrier frequencies and correlating each of the multiple relative sets of priority levels with respective different WCD operational characteristics. In particular, the message may specify a first correlation of one relative set of priority levels with one WCD operational characteristic and includes a second correlation of a different relative set of priority levels with a different WCD operational characteristic. The WCD may select one of the relative sets of priority levels responsive to the WCD having a WCD operational characteristic that the message correlates with the selected relative set of priority levels. The WCD may then apply the selected relative set of priority levels.
Abstract translation: 如所公开的，当无线通信设备（WCD）在基站的特定载波频率上空闲时，基站可以接收该基站广播的消息，该消息指定为一组基站定义的多个相对优先级集合 载波频率，并且将多个相对优先级级别中的每一个与相应不同的WCD操作特性相关联。 具体地，消息可以指定一个相对优先级级别与一个WCD操作特性的第一相关性，并且包括不同相对优先级级别与不同WCD操作特性的第二相关。 WCD可以响应于具有WCD操作特性的WCD来选择相对的优先级中的一个，该消息与所选择的相对优先级等级相关联。 然后，WCD可以应用所选择的相对优先级集合。

Abstract: Disclosed is a method and system to manage paging channels in a wireless communication network. When the network encounters a situation where the network is to transmit an access response message in a coverage area to a mobile station, the network will determine whether the mobile station is in an access handoff state. If not, the network will transmit the message to the mobile station on a paging channel selected based on the mobile station's identifier. Otherwise, the network will transmit the message to the mobile station on both that paging channel and a default paging channel (e.g., primary channel) selected without consideration of the mobile station's identifier. This process can help avoid an access handoff failure. Further, a radio access network may opt to use the default paging channel in response to the wireless coverage area having a different number of paging channels than an adjacent coverage area.
Abstract translation: 公开了一种在无线通信网络中管理寻呼信道的方法和系统。 当网络遇到网络要向覆盖区域发送接入响应消息的情况时，网络将确定移动站是否处于接入切换状态。 如果不是，网络将基于移动台的标识符选择的寻呼信道将消息发送到移动台。 否则，在不考虑移动台的标识符的情况下，网络将在该寻呼信道和默认寻呼信道（例如，主信道）两者上向移动台发送消息。 此过程可以帮助避免访问切换失败。 此外，无线电接入网络可以响应于具有与相邻覆盖区域不同数量的寻呼信道的无线覆盖区域，可以选择使用默认寻呼信道。

Abstract: One or more indications of signal quality as measured by a wireless communication device (WCD) served by a radio access network (RAN) may be transmitted from the WCD to the RAN. A determination may be made that the one or more indications of signal quality meet or exceed a threshold signal quality. Possibly based on the one or more indications of signal quality meeting or exceeding the threshold signal quality, the WCD may bundle at least some hybrid automatic repeat request (HARD) acknowledgments that the WCD transmits to the RAN.

Abstract: It may be determined that a hybrid automatic repeat request (HARQ) transmission schedule from a radio access network (RAN) to wireless communication devices (WCDs) uses HARQ acknowledgment bundling for a first set of two or more data slots, and that the HARQ transmission schedule does not use HARQ acknowledgment bundling for a second set of one or more data slots. It may further be determined that a first WCD supports carrier aggregation when receiving communications from the RAN, and that a second WCD does not support carrier aggregation when receiving communications from the RAN. Based on the first WCD supporting carrier aggregation, the RAN may transmit a first data to the first WCD in the first set of data slots. Based on the second WCD not supporting carrier aggregation, the RAN may transmit a second data to the second WCD in the second set of data slots.
Abstract translation: 可以确定，从无线电接入网络（RAN）到无线通信设备（WCD）的混合自动重传请求（HARQ）传输调度对于两个或更多个数据时隙的第一组使用HARQ确认捆绑，并且HARQ传输 时间表不对一个或多个数据时隙的第二组使用HARQ确认捆绑。 还可以确定当从RAN接收通信时第一WCD支持载波聚合，并且当从RAN接收通信时，第二WCD不支持载波聚合。 基于第一WCD支持载波聚合，RAN可以在第一组数据时隙中将第一数据发送到第一WCD。 基于不支持载波聚合的第二WCD，RAN可以在第二组数据时隙中将第二数据发送到第二WCD。

Abstract: Disclosed herein is a method and apparatus for managing transmission of air interface measurement reports from a UE to its serving base station. In accordance with the disclosure, a UE will generally transmit such measurement reports on subcarriers having particular subcarrier spacing. However, if and when the UE detects threshold poor air interface performance, such as threshold weak signal strength from its serving base station, the UE will responsively transition to instead transmit measurement reports to its serving base station on subcarriers having smaller subcarrier spacing.

Abstract: Embodiments described herein may help to provide a delayed zone-update process. An exemplary method may involve a user entity, which is initially operating in a first of a plurality of multi-coverage-area zones in a radio access network (RAN), subsequently determining that the user entity has moved into a second multi-coverage-area zone of the RAN, wherein the user entity is located in a first coverage area of the second multi-coverage-area zone. In response, the user entity may refrain from sending a registration message to register in the second multi-coverage-area zone until the earlier of: (i) a threshold period of time elapsing and (ii) the user entity moving into another coverage area in the second multi-coverage-area zone that is different from the first coverage area.
