Abstract: Disclosed is a method and apparatus to help facilitate providing of multiple Downlink Control Information (DCI) messages that separately schedule downlink communication of bearer data to a wireless communication device (WCD) in a given sub-frame, to help ensure receipt of such multiple DCI messages by the WCD. As disclosed, a base station will include in at least one such DCI message an indication that there is in the sub-frame at least one other such DCI message. When the WCD receives and reads the one such DCI message, the WCD may thereby learn from the indication that there is at least one other such DCI message in the sub-frame. The WCD may then search for and find the at least other such DCI message in the sub-frame and/or may use the indication as a basis to verify receipt of all such DCI messages in the sub-frame.

Abstract: A method and system for dynamically selecting call setup procedure based on channel quality. While a wireless communication device (WCD) is being served by a first radio access network (RAN), a network node receives an indication of a communication quality of the at least one channel used by the first RAN to serve the given WCD. Then, the network node selects a call setup procedure for establishing a call to be served by a second RAN based on the received indication of the communication quality of the at least one channel, where the selected call setup procedure comprises the given WCD transitioning to be served with the call by the second RAN. Next, the network node signals to invoke setup of the call using the selected call setup procedure.

Abstract: A method and system to help avoid a failed eCSFB call setup in the presence of handover. While a WCD is being served by a base station of a first network, the base station may detect both a fallback trigger and a handover trigger. The fallback trigger may be a trigger to initiate a fallback setup procedure, where the fallback setup procedure involves execution of a sequence of steps including a particular step. The handover trigger may be a trigger to initiate a handover procedure. The base station determines that the handover trigger was detected before execution of the particular step of the fallback setup procedure. Responsive to determining that the handover trigger was detected before execution of the particular step, the base station (a) foregoes the fallback setup procedure and (b) transmits to the WCD a message directing the WCD to establish communication with the second network.

Abstract: Disclosed is a method and system of managing an allocation of resources in a wireless communication system. According to the disclosure, a base station may receive or otherwise determine an indication of radio frequency (RF) conditions being perceived by a given user equipment device (UE). Based on that indication, the base station may make a decision of whether to use a first resource limitation or a second resource limitation for data transmissions to the given UE, where the second resource limitation generally allows for a lesser extent of resources to be allocated than the first resource limitation in weaker RF conditions. For instance, the base station may decide to use a bit-rate limitation for threshold strong RF conditions and a resource-block limitation for threshold weak RF conditions. Thereafter, the base station may allocate resources for a data transmission to the given UE in accordance with the decision.

Abstract: It may be determined that a HARQ transmission schedule from a RAN to a WCD includes HARQ acknowledgment bundling. An indication of signal quality as measured by the WCD may be received by the RAN. The indicated signal quality may be associated with a first transmission rate. The RAN may determine a first set of one or more data slots of the HARQ transmission schedule for which the WCD bundles HARQ acknowledgments. In response to this determination, one or more HARQ subpackets may be transmitted to the WCD in the first set of one or more data slots. The one or more HARQ subpackets may be transmitted at a second transmission rate that is less than the first transmission rate.
Abstract translation: 可以确定从RAN到WCD的HARQ传输调度包括HARQ确认捆绑。 由WCD测量的信号质量的指示可以由RAN接收。 指示的信号质量可以与第一传输速率相关联。 RAN可以确定WCD捆绑HARQ确认的HARQ传输调度的一个或多个数据时隙的第一组。 响应于该确定，一个或多个HARQ子分组可以在一个或多个数据时隙的第一组中被发送到WCD。 一个或多个HARQ子分组可以以小于第一传输速率的第二传输速率传输。

Abstract: Disclosed is a method and system for allocating uplink air interface resources in a manner that allows particular user equipment devices (UEs) to apply less attenuation than may be specified more generally for UEs served by a base station of a wireless service provider. The base station may operate on a carrier band, serving UEs that are subscribers of the wireless service provider as well as UEs roaming in the base station's coverage area from another service provider. To avoid uplink transmission power leakage across the edges of the carrier band, the base station may broadcast a message to all the UEs notifying them to attenuate their respective transmission levels. The base station may allocate uplink air interface resources to subscribing UEs from a particular portion of the carrier band that allows them to transmit using less attenuation than roaming UEs and still avoid power leakage across the band edges.
Abstract translation: 公开了一种用于以允许特定用户设备设备（UE）对无线服务提供商的基站所服务的UE更一般地规定的衰减来应用更少的衰减的方式和系统，用于分配上行链路空中接口资源。 基站可以在载波频带上操作，为作为无线服务提供商的订户的UE服务，以及在基站的覆盖区域中从另一服务提供商漫游的UE。 为了避免载波频带边缘的上行链路传输功率泄漏，基站可以向所有的UE广播消息，通知它们衰减它们各自的传输电平。 基站可以分配上行链路空中接口资源以从载波频带的特定部分订阅UE，从而允许它们使用比漫游UE更少的衰减进行发送，并且仍然避免跨频带边缘的功率泄漏。

Abstract: A base station that serves a plurality of wireless communication devices (WCDs) will group the WCDs into physical hybrid automatic repeat request (HARQ) channel (PHICH) groups based on channel quality reported by the WCDs and will then differentially allocate transmission power among the PHICH groups, so as to provide higher transmission power for transmission to PHICH groups of WCDs that reported lower channel quality, while providing lower transmission power for transmission to PHICH groups of WCDs that reported higher channel quality.

Abstract: A system and method for reuse of identifiers for contention-free random access requests by wireless communication devices (WCDs) to a network are disclosed. A base station can configure two or more air-interface resources for concurrent, non-interfering transmissions by two or more different WCDs of identical random access requests to the base station. The base station may then assign an identical identifier for contention-free random access requests to two or more WCDs, while assigning the WCDs different ones of the two or more air-interface resources configured for the concurrent, non-interfering transmissions. The two or more WCDs can then concurrently transmit identical contention-free random access requests that do not interfere with one another. By way of example, the air-interface resources can be different instances of a physical random access channel, each instance corresponding to a different resource block of a common uplink subframe in a long-term evolution (LTE) system.

Abstract: A radio access network (RAN) may be configured to manage paging of a wireless communication device (WCD). The RAN may initiate a paging process to page the WCD, and the paging process may comprise the RAN transmitting to the WCD a defined sequence of page attempts until the RAN receives a page response from the WCD or the RAN has transmitted a final page attempt of the sequence. After the RAN has transmitted at least one page attempt of the sequence but before the final page attempt of the sequence has been transmitted, the RAN may determine that the RAN has not received the page response from the WCD, and that the WCD is currently engaged in active data communication, and the RAN may responsively discontinue the paging process.
