Abstract
Uplink communication techniques for non-ideal backhaul scenarios are described. In one embodiment, for example, user equipment (UE) may comprise logic, at least a portion of which is in hardware, the logic to receive an uplink (UL) communication process configuration message identifying a configured UL communication process for the UE, the UL communication process configuration message comprising a cell identifier and one or more configuration information elements (IEs), each configuration IE comprising configuration information for UL communications on the part of the UE, the logic to send a UL message based on the configuration information comprised in at least one of the configuration IEs. Other embodiments are described and claimed.
Description
- This application claims priority to U.S. Provisional Patent Application No. 61/859,121, filed Jul. 26, 2013, the entirety of which is hereby incorporated by reference.
- Embodiments herein generally relate to communications between devices in broadband wireless communications networks.
- In an evolved Universal Mobile Telecommunications System Terrestrial Radio Access Network (E-UTRAN), there may be regions in which the coverage areas of multiple evolved node Bs (eNBs) overlap. In one example, a small cell may overlap with another small cell and/or with an overlaid macrocell. In another example, in an edge region of one macrocell, coverage may be available not only from an eNB of that macrocell but also from an eNB of an adjacent macrocell. In some cases, it may be desirable that a user equipment (UE) residing in a region of overlapping coverage make use of the overlapping coverage to send uplink (UL) data to multiple eNBs at the same time. For example, it may be desirable that an eNB enter a dual-connectivity operation mode enabling concurrent UL transmission to both a small cell eNB and a second small cell eNB or an overlaid macrocell eNB. In another example, it may be desirable that an eNB utilize coordinated multipoint (CoMP) techniques to enable concurrent UL transmission to multiple eNBs and/or remote radio heads (RRHs).

where maxUL-Proc-r12 represents a maximum number of UL communication processes that may be configured. It is worthy of note that the suffix “r12” is featured in the above example to indicate that the depicted IE may be associated with 3GPP Release 12 in various embodiments. However, the embodiments are not limited to this example. - In some embodiments, communications component 306 may be operative to send a UL message or signal based on the configuration information comprised in one or
more configuration parameters 314. In various embodiments, communications component 306 may be operative to send a UL message or signal over a wireless channel based on configuration information comprised in aconfiguration parameter 314 associated with the wireless channel. For example, communications component 306 may be operative to send a UL message over a PUCCH of a small cell corresponding tocell identifier 312 based on configuration information comprised in aconfiguration parameter 314 associated with the PUCCH of the small cell. In some embodiments, communications component 306 may be operative to format a UL signal that it sends based on configuration information comprised in aconfiguration parameter 314 associated with the UL signal. For example, communications component 306 may be operative to format a periodic or aperiodic sounding reference signal (SRS) 316 that it sends based on configuration information comprised in aconfiguration parameter 314 associated with the periodic oraperiodic SRS 316. The embodiments are not limited to these examples. - In various embodiments, communications component 306 may be operative to receive multiple UL communication process configuration messages 308, each corresponding to a respective UL communication process that has been configured for
apparatus 300 and/orsystem 340. For example, in some embodiments, in addition to the UL communication process configuration message 308 that it receives fromeNB 350, communications component 306 may be operative to receive a second UL communication process configuration message 308-2 from an eNB 360. In various embodiments, the eNB(s) that configureapparatus 300 and/orsystem 340 with the multiple UL communication processes may utilize collision avoidance techniques to configure the multiple processes in such a way as to ensure that they will not collide. In some such embodiments, communications component 306 may be operative to perform UL communications based on an assumption that the processes defined by the multiple UL communication process configuration messages 308 will not collide. In various such embodiments, if a collision between UL communication processes does occur, communications component 306 may be operative to regard the collision as an error case. The embodiments are not limited in this context. - In some embodiments, rather than relying on collision avoidance on the eNB side, communications component 306 may be operative to apply one or more priority rules to handle collisions between UL communication processes. In various embodiments, in response to detecting a collision between two UL communication processes, communications component 306 may be operative to apply one or more such priority rules to select a UL communication process for which to drop some or all of a transmission. In some embodiments, communications component 306 may be operative to prioritize UL communication processes based on the cell types of the respective cells to which they correspond. For example, in various embodiments, communications component 306 may be operative to prioritize macrocell processes over small cell processes, or vice versa. In some embodiments, communications component 306 may be operative to prioritize UL communication processes based on the types of eNBs to which they correspond. For example, in various embodiments, communications component 306 may be operative to prioritize MeNB processes over SeNB processes, or vice versa. In some embodiments, communications component 306 may be operative to prioritize UL communication processes based on their UL process IDs. For example, in various embodiments, communications component 306 may be operative to prioritize UL communication processes with lower UL process IDs over those with higher UL process IDs, or vice versa. In some embodiments, communications component 306 may additionally or alternatively be operative to prioritize UL communication processes based on priorities that are configured via radio resource control (RRC) signaling. The embodiments are not limited in this context.
- In various embodiments, in order to select a specific transmission to partially or fully drop, communications component 306 may be operative to apply one or more content type-based priority rules. In some embodiments, communications component 306 may be operative to apply one or more content type-based priority rules to select from among multiple transmissions associated with a same UL communication process. In various embodiments, communications component 306 may additionally or alternatively be operative to apply one or more content type-based priority rules in conjunction with the determination of a UL communication processes for which a transmission is to be partially or fully dropped. In some embodiments, each content type-based priority rule may be usable to prioritize transmissions based on characteristics of the contents of those transmissions. In various embodiments, communications component 306 may be operative to prioritize transmissions based on the quality of service (QoS) levels associated with their contents. In some embodiments, communications component 306 may be operative to prioritize transmissions that contain channel state information (CSI) based on the types of CSI that they contain. For example, in various embodiments, communications component 306 may be operative to prioritize transmissions that contain CSI based on the CSI types defined in 3GPP TS 36.213. In a particular example, communications component 306 may be operative to assign a top level of priority to transmissions that contain CSI of types 3, 5, 6, or 2a, may be operative to assign a middle level of priority to transmissions that contain CSI of types 2, 2b, 2c, or 4, and may be operative to assign a bottom level of priority to transmissions that contain CSI of
types 1 or 1a. In some embodiments, communications component 306 may be operative to prioritize transmissions based on their data/signal type. For example, in various embodiments, communications component 306 may be operative to prioritize UL control information (UCI) transmissions over data channel transmissions and/or SRS transmissions. It is to be understood that the embodiments are not limited to these examples. - In some embodiments, more than one of the aforementioned prioritization rules may be applied in combination. For example, in various embodiments, communications component 306 may be operative to prioritize among multiple CSI transmissions based on their CSI types, their associated cell indexes, and their associated UL process IDs. In various embodiments, for example, communications component 306 may be operative to prioritize among multiple CSI transmissions based first on their CSI types, second on their associated UL process IDs, and third on their associated cell indexes. As an additional example, in some other embodiments, communications component 306 may be operative to prioritize among multiple CSI transmissions based first on their CSI types, second on their associated cell indexes, and third on their associated UL process IDs. It is to be appreciated that these criteria may be applied in any order, and the embodiments are not limited to the orders reflected in the previous two examples. In some embodiments, if a particular prioritization criterion does not provide differentiation between the various transmissions being considered, it may be omitted from the prioritization. For example, communications component 306 may be operative to omit a process ID criterion when selecting from among transmissions that are all associated with a same UL communication process. In various embodiments, communications component 306 may be operative to utilize one or more default values when considering criteria for which values have not yet been generated and/or are not available. For example, when considering a transmission associated with a UL communication process for which a UL process ID is not available, communications component 306 may be operative to utilize a default UL process ID. The embodiments are not limited to these examples.
- In some embodiments, communications component 306 may be operative to handle some process collisions at a configuration level. In various embodiments, communications component 306 may be operative to receive
conflicting configuration parameters 314 associated with a same UL channel or signal. In some embodiments, communications component 306 may be operative to receive suchconflicting configuration parameters 314 in different respective UL communication process configuration messages 308. In various other embodiments, communications component 306 may be operative to receive suchconflicting configuration parameters 314 in a same UL communication process configuration message 308. In some embodiments, in order to resolve such a conflict, communications component 306 may be operative to disregard part or all of the configuration information comprised in one of theconflicting configuration parameters 314. The embodiments are not limited in this context. - In various embodiments, communications component 306 may be operative to implement UL power control for one or more UL channels and/or signals based on configuration information comprised in one or
more configuration parameters 314. In some embodiments, for example, communications component 306 may be operative to determine transmit powers for PUSCH, PUCCH, and/or SRS transmissions according to the equations specified in sections 5.1.1.1, 5.1.2.1, and/or 5.1.3.1 of 3GPP TS 36.213. In various embodiments, aconfiguration parameter 314 that corresponds to a particular UL channel or signal may comprise the values needed to determine a transmit power for that UL channel or signal based on its corresponding equation. For example, aconfiguration parameter 314 that corresponds to a PUSCH of a small cell may comprise the values needed to determine a transmit power for transmission over the PUSCH of the small cell via the equations specified in section 5.1.1.1 of 3GPP TS 36.213. In some embodiments, in conjunction with determining such UL transmit powers, a pathloss to the destination may be determined based oncell identifier 312. The embodiments are not limited in this context. - In various embodiments, communications component 306 may be operative to utilize information received in one or more UL communication process configuration messages 308 when performing power headroom (PH) reporting on behalf of
apparatus 300 and/orsystem 340. In some embodiments, communications component 306 may be operative to perform a PH reporting procedure according to section 5.4.6 of 3GPP TS 36.321. In various embodiments, in conjunction with the PH reporting procedure, communications component 306 may be operative to determine atype 1 PH and/or a type 2 PH for any given serving cell ofapparatus 300 and/orsystem 340. In some dual-connectivity embodiments, the received UL communication process configuration messages 308 may identify multiple serving cells forapparatus 300 and/orsystem 340, and communications component 306 may be operative to determinerespective type 1 and/or type 2 PHs for each of the multiple serving cells. In various embodiments, communications component 306 may be operative to send a respective PH report (PHR) 318 for each configured UL communication process regarding which it receives a UL communication process configuration message 308. In some embodiments, communications component 306 may be operative to include PHs for multiple processes in asingle PHR 318. In various embodiments, communications component 306 may be operative to include theUL process IDs 310 for the multiple processes in a media access control (MAC) element of thePHR 318. - In some embodiments, communications component 306 may be operative to determine the PH values that it includes in
PHRs 318 based on the PUSCHs over which it sends thosePHRs 318. In various embodiments, when sending aPHR 318 over a given PUSCH, communications component 306 may be operative to identify a UL communication process corresponding to that PUSCH and to calculate a PH to include in thePHR 318 based only on power setting configurations associated with that UL communication process. In some embodiments, communications component 306 may be operative to send aPHR 318 whenever a pathloss associated with any UL communication process changes by more than a threshold. As such, in various embodiments, even when UL transmissions are distributed across multiple destination cells in time or involve concurrent transmission to multiple destination cells, proper PH values may be reported to the serving eNBs. The embodiments are not limited in this context. - In some embodiments, a common timing advance (TA) may be implemented for all the UL communication processes that are configured for
apparatus 300 and/orsystem 340. In various other embodiments, different TAs may be implemented for different UL communication processes. In some such embodiments, the UL communication process configuration message 308 corresponding to any particular UL communication process may include aconfiguration parameter 314 specifying a configured TA for that process. In various embodiments, for example, aconfiguration parameter 314 that comprises an RRC parameter may be used to specify the configured TA for the corresponding process. In some dual-connectivity embodiments, an RRC parameter specifying TA type 0 may indicate that the corresponding process has been configured with a TA that corresponds to a serving macrocell, while an RRC parameter specifyingTA type 1 may indicate that the corresponding process has been configured with a TA that corresponds to a serving small cell. The embodiments are not limited to this example. - In various UE-CoMP embodiments,
apparatus 300 and/orsystem 340 may utilize dynamic or semi-static point selection, according to which it may be dynamically or semi-statically served by a small cell eNB and a macrocell eNB that operate on a same carrier frequency. In some such embodiments, communications component 306 may be operative to receive multiple UL communication process configuration messages 308 that correspond to UL channel/signal configurations for the multiple respective eNBs. In various embodiments, for example, communications component 306 may be operative to receive a first UL communication process configuration message 308 that corresponds to a periodic CSI (pCSI) configuration for reportingpCSI 320 to the small cell eNB, and may be operative to receive a second UL communication process configuration message 308 that corresponds to a pCSI configuration for reportingpCSI 320 to the macrocell eNB. In some embodiments, each pCSI configuration may comprise and/or specify a PUCCH format 2 resource, a reporting periodicity, a configuration offset, and/or one or more other parameters. In various embodiments, in order to initiate an adjustment of the transmission orientation of the small cell eNB, communications component 306 may be operative to sendpCSI 320 for both the small cell and the macrocell. The embodiments are not limited in this context. -
