Description

Hybrid open loop and closed loop beamforming

Embodiments herein generally relate to communication between devices in a broadband wireless communication network.

In an open loop beamforming system, the beamforming entity typically selects one or more transmit beams to use without any feedback information from the remote entity receiving the transmission from the beamforming entity. In a closed loop beamforming system, the beamforming entity typically selects one or more transmit beams to use based on feedback information from the remote entity. Open loop beamforming systems generally provide less computational and communication overhead burden associated with beamforming selection procedures. However, such open loop beamforming systems lack robustness due to the low efficiency of certain selected beams. Closed loop beamforming systems generally provide improved beam performance at the expense of significant computational and communication overhead. Improved beamforming systems that overcome these deficiencies of conventional open loop and closed loop beamforming systems have not been developed, including beamforming techniques for 5G systems.

FIG. 1 depicts an exemplary operating environment 100, such as may be representative of some embodiments in which hybrid open loop and/or closed loop beamforming techniques may be implemented. Operating environment 100 may include mobile device 102 and cellular base station 104. The mobile device 102 can communicate with the base station 104 via the wireless communication interface 106. The mobile device 102 can be a smart phone, tablet, notebook, netbook, or other mobile computing device capable of wirelessly communicating with one or more wireless communication networks. For example, mobile device 102 can be a user device (UE). The base station 104 can be a cellular base station such as, for example, an evolved node B (eNB). The base station 104 can be a serving cell of the UE 102, such as, for example, primary or secondary serving cells. The wireless communication interface 106 can be, for example, any of the wireless networks described herein. A standard or standard wireless interface, including, for example, a 4G, LTE, or 5G wireless network. The mobile device 102 and the base station 104 can each implement the hybrid open loop and/or closed loop beamforming techniques described herein.

Beamforming is a signal processing technique used to control the directivity of the transmission and reception of wireless signals. By controlling the directional pattern of the antenna, beamforming can improve the signal quality at the receiver being referred to while reducing interference. Beamforming may be a key feature in 5G systems, which may operate in higher frequency bands with less attractive degradation characteristics.

For wireless communication interface 106 that provides a communication connection between mobile device 102 and base station 104, beamforming can be open loop, closed loop, or hybrid open loop and closed loop. In open loop beamforming, a beamforming entity (e.g., mobile device 102 or base station 104) selects its own beam without any information from any other entity (e.g., a remote device or entity that can communicate with the beamforming entity). In closed loop beamforming, the beamforming entity may obtain some form of information provided by other devices in communication with the beamforming entity. The beam selection of the beamforming entity may be based on available information from the remote device. Hybrid open loop and closed loop beamforming, as further described herein, may include both open loop and closed loop beamforming features.

Closed loop beamforming procedures can be implicit or clear. For implicit closed loop beamforming, a beamforming entity (e.g., mobile device 102 or base station 104) may select a beam (e.g., another device in communication with the beamforming entity) based on observations of non-intelligible information provided by other entities. This non-understood information may include a reference signal. For understanding closed loop beamforming, with beams The other entity that forms the physical communication selects the preferred beam. Beam selection can be provided to the beamforming entity as feedback information. The beam selection may be based on a reference signal previously transmitted by the beamforming entity. The reference signal can be carried or transmitted through one or more candidate beams. Beam selection based on well-understood feedback can use a limited size beam index (BI) to uniquely identify candidate beams based on distinct BI values.

Any performance gain achievable in a beamforming system depends on the selected beam. Inaccurate beam selection can adversely affect performance gains. There are several reasons for beam inaccuracy, including, for example, changes in communication channels (such as beamforming entities or other entities that may move quickly), crosstalk between beams in multiple beam systems, and between uplink and downlink transmissions. The change (e.g., the propagation characteristics may vary such that the uplink beam is selected sub-optimal based on downlink information). To improve beam selection, many beamforming selection techniques focus on closed loop solutions. However, pure closed loop beamforming systems add significant burden and cost to the communication system in terms of increased computational and indirect burden of communication.

The hybrid open loop and/or closed loop beamforming techniques described herein enable pre-selected and refined open loop beamforming for closed loop beam sets. In various embodiments, efficient refinement of the initially selected beam is provided by having the remote device indicate a preferred subset of beams to the beamforming entity based on the erroneous detection of the data block transmitted using the initially selected beam. In various embodiments, the techniques described herein provide enhanced efficiency (e.g., by reducing the indirect burden of signaling or feedback) and improved robustness by combining open loop and closed loop features (e.g., by improved beamforming options). And/or sex can). In various embodiments, the hybrid open loop and/or closed loop beamforming techniques described herein cycle through multiple beams in the time domain (or frequency domain), with each beam being used for one or more code blocks. In various embodiments, the beam selection can be made adaptive by reducing the set of beams for retransmission (e.g., in a hybrid automatic repeat request (HARQ) scheme) based on the error detection results of the code blocks associated with the particular beam. The hybrid open loop and/or closed loop beamforming techniques described herein are applicable to 3GPP LTE Release 14 and 5G systems, but are not so limited. In various embodiments, the frequency domain beam cycling techniques described herein (eg, hybrid open loop and/or closed loop analog beamforming techniques) provide robustness due to beam diversity because different beams can carry different The signal is such that when combined with channel coding, protection against any single beam failure is provided. The various frequency domain beam cycling techniques described herein may use multiple beams to transmit information (such as data, control, or reference signals), where the beams cycle through available frequency resources (eg, frequency bands) in a predetermined manner.

2 illustrates an example of a logic flow 200 that may represent one or more implementations of hybrid open loop and closed loop beamforming techniques in accordance with various embodiments. For example, logic flow 200 may represent operations that may be performed by mobile device 102 (e.g., UE) or base station 104 (e.g., an eNB) in operating environment 100 of Figure 1 in some embodiments.

At 202, the beamforming entity can transmit one or more reference signals using one or more candidate transmit beams. The reference signal can be transmitted to a remote entity (eg, a second beamforming entity). The reference signal can have a periodic signal of a large period. For example, the reference signal can be transmitted relatively infrequently. Candidate transmission The beam can be predefined and known to the beamforming entity and the remote entity receiving the reference signal. Candidate transmit beams can each be associated with a unique identifier or identification (ID). For a bidirectional beamforming system, an entity receiving a reference signal can select a receive beam as one or more of the candidate transmit beams.

At 204, the remote entity receiving the reference signal can select a preferred set of transmit beams. The preferred set of transmit beams can be a subset of the candidate transmit beams. The remote entity can use various metrics to select a preferred set of transmit beams. For example, the preferred set of transmit beams may be based on the noise ratio of the received reference signal, the highest signal strength of the received reference signal, and/or an error associated with recovering, decoding, or processing the received reference signal. A preferred set of transmission beams is determined. At 204, a preferred transmit beam set can be transmitted by the far end entity to a beamforming entity that transmits the reference signal using the candidate transmit beam. Accordingly, at 204, the beamforming entity can receive feedback information from the remote entity. In various embodiments, the feedback information may include identification of a preferred set of transmit beams using, for example, a predefined transmit beam identifier (ID) associated with each transmit beam. For example, the remote entity may provide one or more IDs to the beamforming entity to indicate the preferred set of transmit beams. The ID associated with each transmit beam can be pre-determined or predefined in comparison to the beamforming entity and the far end device. Since this portion of the logic flow 200 can rely on feedback information, step 204 can be considered to provide a closed loop portion of the logic flow 200.

At step 206, the beamforming entity may transmit the data signal using the set of transmission beams selected and/or identified by the remote entity. The selected transmit beams can each transmit one or more data signals. The data signal can be transmitted, for example, through a sub-frame, where the transmission beam is used for one or more code blocks of the sub-frame. For For code block groups, the use of transmit beams can be cycled through selected transmit beam groups. The association of a particular transmission beam (e.g., beam ID) to a particular set of data signals (e.g., a group of code blocks containing one or more code blocks) may follow a predefined pattern in accordance with the identified set of transmitted beams. In various embodiments, the transmit beam can be used in numerical order in accordance with the transmit beam ID and by cycling the IDs. The beamforming entity and the remote entity receiving the data signal from the beamforming entity can know a predetermined defined pattern or cycle of the selected set of transmission beams. Step 206 can be viewed as providing an open loop portion of logic flow 200.

In various embodiments, the data signals transmitted by the beamforming entity may be partitioned into transmission time intervals (TTIs), where TTI represents a time format of one or more blocks containing the encoded signals. The block of the encoded signal can be represented as a code block. In various embodiments, decoding a block of code may be performed incoherently with other code blocks. Moreover, in various embodiments, the TTI can be considered a subframe. The technology is not limited to these embodiments.

In various embodiments, an error detection mechanism may be employed per code block, such as, for example, a cyclic redundancy check (CRC). Therefore, each code block can be decoded into a "pass" or "fail" result. If the code block is not decoded correctly (eg, if the code block is decoded into a "failed" result), the receiver may request retransmission of the error code block. In various embodiments, the beamforming entity and the receiving entity involved in the fulfillment of the logic flow 200 may implement a HARQ retransmission scheme. Accordingly, each subframe carrying the encoded data signal may contain one or more HARQ blocks such that each HARQ block contains one or more code blocks. In various embodiments, the HARQ mechanism, retransmission techniques, and data signal partitioning and clustering are correct Should be based on the transport block (TB) based 3GPP LTE HARQ mechanism. In various embodiments, each code block corresponds to an OFDM symbol.

In general, in various embodiments, the hybrid beamforming techniques described herein are applicable to the use of beams for each encoded data block, and the data blocks can be separately and independently decoded and can include their own error correction/ The detection mechanism, so if there is incorrect decoding, the divided data blocks can be retransmitted.

At 208, the remote entity may attempt to decode each code block transmitted by the beamforming entity. As previously discussed, in various embodiments, each received code block or group of encoded data can be transmitted from a particular transmission beam of the preferred transmission beam set. If any code block or group of encoded data is not decoded correctly (eg, if the decoding operation of the code block is a failure), the remote entity may provide such information to the beamforming entity. This information can be viewed as feedback information transmitted by the remote device and received by the beamforming device.

In various embodiments, the HARQ feedback for a HARQ block containing at least one code block that is not correctly decoded may be a non-acknowledgement (NACK) message. In conjunction with providing a NACK or other decoding failure message as feedback information, the remote entity may provide an indication of the second set of transmission beams. This second set of transmit beams can be a subset of the first preferred set of transmit beams. The second set of transmit beams may exclude any transmit beams from the first set of transmit beams associated with the failed decoding result. For example, a particular transmit beam associated with a code block that produces a failed decoding result may be excluded from the second set of transmit beams. In various embodiments, the second set of transmit beams identified by the remote device to the beamforming entity may be a transmit beam from a first set of transmit beams associated with the successfully decoded code block.

At 208, a second set of transmit beams identified by the remote device is received by the beamforming entity. In various embodiments, to reduce the indirect burden of communication, the indication or indicator from the remote device may have a format that is shorter or smaller than the indicator used to identify the first set of transmission beams. For example, the identifier can be an indication of the location of a particular transmission beam within the first set of transmit beams (e.g., the identifier indicates that a fifth transmit beam within the first set of transmit beams will form part of a second set of transmit beams). In various embodiments, an indicator from a remote entity can identify a single transmit beam. Step 208 can be viewed as providing a closed loop portion of logic flow 200.

At 210, the beamforming entity can retransmit one or more data signals using the transmit beams from the second set of transmit beams. The data signal may be transmitted by cycling through the second set of transmission beams in a known, predefined manner (e.g., based on the numerical order of the ID of the transmission beam). In various embodiments, the beamforming entity may retransmit all of the data signals of the entire HARQ block (eg, including previously successfully decoded code blocks) in accordance with the second set of transmission beams. In various embodiments, the beamforming entity may only retransmit code blocks that were not successfully decoded before. Step 210 can be viewed as providing an open loop portion of logic flow 200.

In various embodiments, step 208 can be performed as an open loop component of logic flow 200. That is, the beamforming entity may receive an indication of a particular HARQ block or a particular code block failure from the remote device but it does not indicate the second set of transmit beams. In this scenario, in various embodiments, the beamforming entity may shuffle the order of the transmit beams from the first set of transmit beams for use in retransmitting code blocks and/or HARQ blocks. The shuffling of the order of the transmission beams can be seen as a remapping of the transmission beam to the code block (eg, using different transmissions) The beam transmits each retransmitted code block).

The logic flow 200 can be extended to a multiple input and multiple output (MIMO) system that can transmit a single code block using multiple transmit beams. For a MIMO system, in various embodiments, the first and second transmit beam set IDs can indicate a transmit beam combination (eg, a particular indicator can indicate a combination of transmit beams). The identified combination of transmission beams fully identifies all of the transmission beams used to transmit a particular code block.

In general, the hybrid open loop and/or closed loop beamforming techniques described herein are applicable to both time and frequency domain beam loops transmitted using any data structure or data partitioning.

FIG. 3 illustrates an exemplary transmission structure 300 in accordance with the hybrid open loop and closed loop beamforming techniques described herein. The transport structure 300 can be transmitted by a beamforming entity such as, for example, a beamforming entity implementing the logic flow 200. In various embodiments, the transport structure 300 can be provided to the mobile device 102 or base station 104 of the beamforming entity by the operations described herein.

The beamforming entity may transmit one or more reference signals using one or more candidate transmission beams prior to providing the transmission structure 300. Moreover, prior to providing the transmission structure 300, the remote device receiving and processing the reference signal can indicate the first preferred transmission beam set to the beamforming entity. For example, the first preferred set of transmit beams can include four separate transmit beams. The first preferred set of transmit beams can be identified in a variety of ways including, for example, using an ID that uniquely identifies each transmit beam.

After receiving an indication from the remote device identifying the first preferred set of transmit beams, the beamforming entity may use the first preferred set of transmit beams to transmit The data signal to the remote unit. In various embodiments, the data signal can be transmitted in accordance with transmission structure 300. As shown in FIG. 3, the subframe 302 includes a first HARQ block 304 and a second HARQ block 306. Each HARQ block 304 and 306 may contain one or more code blocks 308. In various embodiments, code block 308 may correspond to an OFDM symbol and a HARQ block may correspond to a code block group. Further shown in FIG. 3, each code block 308 is transmitted using a different transmit beam identified by transmit beam identifier 310. The code beam 308 can be transmitted using the transmission beam. In the transmission structure 300, the transmission beams identified by the IDs "2", "4", "7", and "8" are successively used in a round-robin manner. This order of use of the transmit beams can be predefined and known for both beamforming entities and remote devices. For example, FIG. 3 shows that the fourth code block in the HARQ block 304 is transmitted using the transmission beam identified by the fourth small ID value "8".

In various embodiments, transmission structure 300 can be part of a Physical Downlink Shared Channel (PDSCH) with one transmission beam per OFDM symbol and cycle through the first transmission beam set for OFDM symbols. The association of the OFDM symbol with the transmit beam ID may follow the order of the first preferred beam set transmit beam ID and is implicitly known to all entities.

Figure 4a illustrates an exemplary decoding of the transmission structure 300. In various embodiments, the remote device receives the transmission structure 300 of Figure 3 and performs a CRC check. As shown in Figure 4a, each code block 308 is decoded correctly - as indicated by the "pass" indication 402 - or incorrectly decoded - as indicated by the "failed" indication 404. The remote device can indicate to the beamforming device which code blocks 308 failed. In various embodiments, if within the HARQ block 304 or 306 If one less code block 308 fails, the remote device can provide feedback to the beamforming device, the feedback including the HARQ NACK and a second set of identifiers identifying the second set of transmit beams. The identifier of the second transmission beam set may correspond to a unique location of a particular transmission beam used in the previous transmission. In various embodiments, the transmit beam included in the second set includes a beam associated with the CRC pass 402.

Figure 4b depicts an exemplary feedback provided by the remote unit. The feedback provided by the remote device can be HARQ feedback. As shown in FIG. 4b, a success response (ACK) indication 406 is provided for the second HARQ block 306 because all of the code blocks 308 in the second HARQ block 306 as shown in FIG. 4a pass the CRC check. Further shown in FIG. 4b, an unsuccessful acknowledgement (NACK) indication 404 is provided for the first HARQ block 304 because at least the code block 308 in the first HARQ block 304 as shown in FIG. 4a does not pass the CRC check. In conjunction with the NACK indication 404, the remote device can provide an indication 410 identifying the second set of transmission beams. The second set of transmit beams can include one or more transmit beams. In various embodiments, the identification from the remote device may indicate the location of a transmission beam within the HARQ block 304 for retransmission. As shown in Figure 4b, identified as "01", indicating that the second transmission beam from HARQ block 304, i.e., the beam identified by ID "4" as shown in Figure 3, will be used for retransmission.

In a non-limiting example provided with respect to Figures 3 and 4a through 4c, the second set of transmit beams may include up to three beams and at least one beam. In various embodiments, the second set of transmit beams can include a single transmit beam. Therefore, as shown in FIG. 4b, identifying the second transmission beam set The second identifier may be in the form of a two-bit field representing the four possible beam ID positions of the first beam set.

Figure 4c depicts an exemplary HARQ retransmission. HARQ retransmission (denoted as "304-1" in Figure 4c) may include retransmitting each code block 308 from the first HARQ block 304 using the transmission beam identified in indicator 410. It can be seen that each code block 308 is retransmitted using a transmission beam having an ID 310 value of "4". In various embodiments, if more than one transmission beam is identified for the second transmission beam set or is included in the second transmission beam set, the transmission beams can be recycled for the retransmitted code block 308.

As discussed earlier, Figure 3 shows the time domain beam cycle allocation in accordance with the first set of transmission beams. For a single beam transmission with each code block corresponding to the first beam set ID of 2, 4, 7, and 8, Figure 3 shows that beam 2 is assigned to the first OFDM symbol; beam 4 is assigned to the second OFDM symbol The beam 7 is assigned to the third OFDM symbol; and the beam 8 is assigned to the fourth OFDM symbol. Since the OFDM symbols in the block exceed the beams in the first beam set, the beams are repeatedly used in a round-robin manner, and thus the beam 2 is allocated to the fifth OFDM symbol. As shown in Figure 3, the recycling of the beam can be continued into the lower block.

Figures 4a through 4c can be viewed as a display beam refinement operation. As shown in Figure 4a, the CRC check operation reveals that the third and fifth code blocks 308 of the first HARQ block 304 contain errors. As a result, FIG. 4b shows that the HARQ feedback of the first HARQ block 304 includes a NACK 406 and a two-ary field 410 having a value of "01", and a value of "01" indicates that the second beam from the first beam set will form a second Beam set (ie for retransmission). Based on For example, the second beam is a beam identified by an ID value of 310 "4." Therefore, Figure 4c shows the use of the "4" beam. In various embodiments, other indicators may be used to indicate the transmit beam for retransmission. For example, the four-bit field "0101" can be used to indicate that the second and fourth beams from the first set of transmit beams will be used for the second set of transmit beams. In general, which transmission beam will be used for retransmission may be selected based on a transient error check in the subframe (eg, a CRC check) or based on an error check result history of accumulated multiple subframes (eg, by a remote entity).

The data structures, operations, and processes described in relation to Figures 3 and 4 described herein can be implemented using the logic flow 200 described with respect to FIG.

As described above, the hybrid open loop and/or closed loop beamforming techniques described herein provide higher efficiency by significantly reducing the amount and frequency of beam selection feedback compared to fully closed loop beamforming systems, and by providing A certain degree of beam selection diversity provides flexibility for improved beam failure. Compared to a fully open loop beamforming system, the techniques described herein provide more robust beamforming performance by pre-screening and selecting a more probable beam with robustness as the initial open loop beam set. In addition, processing limitations based on mobile devices (e.g., UEs) are more likely to be implemented by mobile devices in the time domain beam cycling techniques described herein, and are more likely to be implemented in future generations of wireless systems (e.g., 5G).

In various communication systems, a feedback mechanism indicating a better modulation and coding rate (MCS) and a better number of MIMO layers can be employed. For many 3GPP systems, a channel quality indicator (CQI) may indicate the former, and a level indication (RI) may indicate the latter. CQI and RI can often be based on dedicated reference Signal-Channel Status Information Reference Signal (CSI-RS). CQI and RI can be conditional on the transmit beam. For example, in clear closed loop beamforming, each CSI-RS can be associated with a particular transmission beam (and thus the beam index refers to the transmission beam). Thus, the beam index, CQI, and RI may form part of Channel State Information (CSI) as feedback information provided to the beamforming entity from the remote device. The various embodiments described herein provide an open loop beamforming system and program that can include an enhanced CSI feedback framework and an enhanced data and control transmission framework. Various embodiments disclose an open loop transmission mode for a communication system that can cyclically transmit beam through frequency resources to provide beam diversity without the need for beam selection feedback from a remote device while reducing the indirect burden of communication.

In various embodiments, the CSI generated by the remote device (eg, mobile device 102 or base station 104) and fed back to the beamforming entity may include CQI and RI but not beam index (BI). For example, in a communication system that will notify CSI for each CSI-RS group (CRG), each CRG may be carried by the entire candidate transmission beam set. The CRG may be transmitted using frequency diversity for all candidate transmit beams (e.g., such that CRGs are simultaneously transmitted on different frequencies for each candidate transmit beam). The candidate transmit beam set can be considered a transmit beam bundle and can be a candidate transmit beam for use with a data channel (eg, PDSCH) and/or a control channel (eg, PDCCH).

In various embodiments, the feedback CSI may be in accordance with a CRG, wherein a transmission beam associated with a particular CRG cycles through an available secondary carrier frequency associated with the CRG. The notified CSI may include a wideband CQI (eg, one or more codeword specific wideband CQIs) and/or a subband CQI. In addition, the notified CSI A wideband RI can be included. In various embodiments, as an alternative, the notified CSI may include CQI and RI measured from each received symbol. For bidirectional beamforming, different receive beams can be used to measure the CSI of each received symbol.

In various embodiments, a beam reference signal (BRS) and a BRS received power (BRS-RP) notification may be provided. In various embodiments, a remote device (e.g., UE 102) may use a BRS-RP for receive beam selection in a bidirectional beamforming system or may use a BRS-RP to cull a beamforming entity (e.g., base station 104) for a particular The set of transmission beams of the far end device. In various embodiments, the remote device can notify one or more BRS-RPs, from one group of multiple BRSs to every BRS-RP. The BRS of the BRS group can be associated with multiple transmit beams and can be associated with a transmit beam bundle. The BRS group can be indicated by Radio Resource Control (RRC) messaging. Alternatively, the grouping of BRSs may depend on the frequency resources of the BRS and the BRS identification (BRS-ID). The number of BRSs in the BRS group can be determined as follows:

among them Indicates the number of resource block groups (RBGs) of the BRS and K is an integer. The number of RBGs and Ks can be configured by, for example, network or RRC communication. In various embodiments, K can be an integer such that K [1, /2].

Each transmit beam 502 can carry the same resource block 504 (using different transmit beams on different frequencies) or different resource blocks. In various embodiments, the remote device receiving the transmission structure 500 can perform channel estimation per RB.

The exemplary transmission structure 600 can include control and/or data information and can represent the structure of the transmission information or control channels and/or data channels.

As shown in Fig. 6, M transmission beams are used - as indicated by transmission beams 602-1, ..., 602-M-1, 602-M. Different transmit beams can be applied to different sub-frames 604. In various embodiments, each sub-frame 604 can represent a TTI. Thus, as shown in FIG. 6, in an example, the number of bundled TTIs may be equal to M. One or more RBs may be included in each TTI and/or subframe 604. At the receiving entity (e.g., mobile device 102 or base station 104), channel estimation can be performed on multiple RBs.

Figures 5 and 6 may represent transmission structures 500 and 600 on the PDSCH, respectively, but are not so limited. In various embodiments, transmission structures 500 and 600 provided by the system as optional transmission schemes may be selected by, for example, RRC messaging. In various embodiments, control channel information may be transmitted in accordance with transmission structures 500 and 600. For example, a physical downlink control channel (PDCCH) may use beamforming in accordance with transmission structures 500 and 600 in accordance with the techniques described herein. According to various embodiments, different transmit beams may carry different RBs (eg, if the PDCCH can be transmitted in a similar manner as the enhanced physical downlink control channel (EPDCCH)). According to various embodiments, the control channel (e.g., PDCCH) may be transmitted by an aggregated transmit beam pattern that may be generated on transmit beams 1 through M. For example, an aggregated transmission beam can be generated as follows:

Where M represents the number of transmission beams and P _j represents the weight of the transmission beam j. Embodiments are not limited to these examples.

The signal or the group of signals can be transmitted across different frequencies (e.g., as shown in Figure 5). For example, each of the transmission beams can each be used to transmit a corresponding signal or a group of signals almost simultaneously. Therefore, different transmission beams can be used for each corresponding frequency range. In various embodiments In the RB, each transmission beam can transmit RBs. In various embodiments, the signal or the group of signals corresponding to each transmit beam may be transmitted sequentially across the same set of frequencies (eg, as shown in FIG. 6). In this scenario, each transmit beam can be used to transmit a sub-frame containing a signal or a group of signals.

In various embodiments, if the number of signals or groups of signals to be transmitted is greater than the number of transmit beams, it may be reused or cycled through the transmit beam in a predefined order. In various embodiments, the transmitted signal can be a data signal, a control signal, a reference signal (eg, BRS), or information representative of an entire RB or subframe. The signal transmitted by the beamforming entity at step 204 can be received and processed by the remote entity. The remote entity may attempt to expose or decode any information provided in the transmitted signal.

At 706, the beamforming entity can receive feedback from a remote device that receives the transmitted signal. Feedback can include information related to the transmission. For example, the feedback may include feedback CSI measured from the CRG. In various embodiments, the provided CSI may include a wideband CQI, one or more codeword specific wideband CQIs, a subband CQI, and/or a wideband RI. In various embodiments, the feedback information does not include BI. In various embodiments, the CSI may include CQI and/or RI measured from each transmitted symbol or group of signals. In various embodiments, such as when transmitting a BRS, the feedback information may include a BRS-RP report. In various embodiments, the received power of any transmitted BRS may be provided. In various embodiments, direct feedback to a particular transmission beam, such as BI, may not be provided. However, in various embodiments, the feedback may provide information to the beamforming entity that may be used to adjust one or more of the transmit beams from the first set of transmit beams.

At 708, the beamforming entity can select a second set of transmit beams from the first set of transmit beams. The second set of transmit beams may be a subset of the first set of transmit beams, but is not so limited. The beamforming entity may select the second set of transmit beams based on, for example, feedback information received from the remote entity, such as feedback information received at step 706. The beamforming entity may select a transmission beam that provides higher performance, particularly in terms of received signal strength or probability of correct decoding.

At 710, the beamforming entity can transmit a signal or group of signals using the second set of transmit beams. The signal transmitted at 710 may be, for example, a retransmission of a signal previously transmitted (e.g., at 704) in accordance with a retransmission scheme (e.g., a HARQ scheme), or may be more likely to be used by a remote entity than a first transmission beam set instead of the first Different sets of signals are received and processed correctly by transmitting beam sets.

As described herein, the beamforming techniques described with respect to Figures 5 through 7 can provide improved efficiency over conventional closed loop beamforming systems because the open loop features of the techniques described herein are limited by remote entities to beamforming. The beam selection feedback of the entity reduces the computation and the indirect burden of the communication.
