METHODS AND DEVICES FOR INFORMATION TRANSMISSION AND RECEPTION AND STORAGE MEDIUM

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims benefit of U.S. Provisional Application No. 62/469,177, filed on March 9, 2017, the contents of which are hereby incorporated by reference in its entirety.

TECHNICAL FIELD

The disclosure relates to the field of wireless communications, and in particular, to methods and devices for information transmission and reception and a computer readable medium.

BACKGROUND

In the 4G LTE system, a physical uplink control channel (PUCCH) is used to carry uplink control information (UCI) from a UE to a base station (e.g., an eNodeB, or eNB) . The UCI includes Ack/Nack for the downlink physical downlink shared channel (PDSCH) transmission, channel state information (CSI) measured by the UE, and a scheduling request (SR) . The PUCCH could be transmitted in assigned physical resource blocks (PRBs) which are located at the edges of the bandwidth. The UCI could also be carried by the physical uplink shared channel (PUSCH) along with the uplink data.

In the 5G NR system, some new design requirements emerge which require low latency and fast feedback. For example, a slot could be split into uplink and downlink portions. The downlink portion consists of one or several symbols and could be transmitted from gNB (similar as eNB in the LTE) to the UEs at the beginning of the slot, which could be followed by a switching period (or guard period (GP) ) in which the UEs complete the switching from downlink reception to uplink transmission. That is further followed by an uplink portion in which the UEs perform unlink transmission on one or more symbols. To achieve fast feedback (and in the end resulting in fast turn around time) , the UEs could be required to feedback Ack/Nack (and maybe with other UCI) for the PDSCH carried by the downlink portion in the same slot. For fulfilling that, a new PUCCH is introduced in the NR, which is transmitted at the end of the slot. As it may only occupy the last one or more symbols in the slot, it is called PUCCH with short duration (or PUCCH in short format, or simply short PUCCH) .

In the 5G NR system, how to design transmission resources for the PUCCH to implement more flexible and efficient uplink information transmission, becomes a problem to be solved.

DETAILED DESCRIPTION

The main content of PUCCH with short duration could be Ack/Nack and the payload could be 1-2 bits or more. The desirable design criterion is that it could have good scalability from low payload (1-2 bits) to large payloads (> 2 bits) . It is also expected the design of short PUCCH with 2-symbol (or possible >2 symbols) could be expanded from that of short PUCCH with 1-symbol. Other aspects that needs to be considered may include frequency diversity, power boosting, good PUCCH capacity, RS overhead, PAPR/CM, interference-diversity, and etc..

The innovation proposes ways of allocating/configuring resource unit/groups which could be used to transmit RS and UCI for NR short PUCCH in a very flexible manner. The method is scalable for different payload and suitable for short PUCCH with one or multiple symbols. It also supports frequency hopping, transmit diversity and CDM multiplexing of different short PUCCHs.

FIG. 1 illustrates a flow chart of a channel transmission method according to some embodiments of the disclosure. In the embodiments, the channel transmission method may be applied to a terminal side. As illustrated in FIG. 1, the channel transmission method may include the following operations illustrated in blocks. The operations may start from block 101.

At block 101, a terminal transmits uplink information on one or more transmission resources, each of the transmission resources including N resource groups, each of the resource groups including one or more resource elements, where N is a positive integer, and the resource elements in each of the resource groups are distributed evenly in frequency domain.

In some embodiments of the disclosure, the uplink information from a plurality of terminals may be transmitted in a same resource group by using a corresponding number of different orthogonal sequences. In some embodiments of the disclosure, the uplink information from a plurality of ports may be transmitted in a same resource group by using a corresponding number of different orthogonal sequences.

As illustrated in FIG. 2, to achieve these requirements and expectations, the resources that are used for short PUCCH could be divided into several groups. FIG. 2 illustrates an example, where the resources (or resource elements (RE) ) in a PRB are divided into three groups. The REs in each group are evenly distributed in frequency and REs from each group are interlaced with REs from other groups. The resources from each group could be used to transmit reference signals (RSs) or UCIs. For example, REs in group 1 could be used to carry RSs, while REs in

groups

2 and 3 could be used to carry UCIs. As it is desirable to have RSs distributed evenly in the frequency for good channel estimation performance, it is therefore to have REs from each group interlaced together. The short-PUCCH from different UEs could be multiplexed using CDM with this structure. For example, as illustrated in FIG. 2, each group in a PRB has 4 REs, and therefore, a length of 4 orthogonal sequences (or quasi-orthogonal ones) could be used to multiplex 4 RS from 4 UEs (e.g., in group 1) . Similarly, 4-bit UCI could be carried if QPSK is used for short-PUCCH, and 2 bits could be transmitted in each group (e.g., in groups 2 and 3) . In each group, a length of 4 orthogonal or quasi-orthogonal sequences could be used to spread the modulated QPSK symbol of UCI and multiplex it with those of other short PUCCHs. In total, 4 short PUCCHs from 4 UEs could be multiplexed in one group of resource elements. Such a multiplexing manner could also be used to achieve transmit diversity. For example, if a UE has 2 transmit antenna ports, and each transmit antenna port uses a different sequence, short PUCCHs from two UEs (each with 2 transmit antennas) could be multiplexed on the same group of resources using the structure illustrated in FIG. 2.

FIG. 2 merely illustrates one way to accomplish the grouping. FIG. 3 illustrates an alternative way for implementing the grouping, in which REs in a PRB are divided into two groups instead of three groups. There are 6 REs in each group. For such grouping, one group could be used to transmit RS and other group could be used to carry UCI. As there are 6 REs in each group, 6 short PUCCHs and their corresponding RSs could be multiplexed in each group of one PRB respectively, using length of 6 orthogonal or quasi-orthogonal sequences. Alternatively, if transmit diversity is used and each antenna port is assigned with a separate sequence, short PUCCHs from 3 UEs each with 2 transmit antenna ports could be multiplexed on a PRB.

As illustrated in FIG. 4, the mentioned examples use one PRB as a resource unit. In fact, to multiplex more short PUCCHs, two alternatives could be used. One is to use the FDM manner, namely, assigning different PRBs (here a PRB is considered as one resource unit) for different short PUCCHs and within each PRB, grouping and CDM could be used to multiplex multiple short PUCCHs. The second way is to use multiple PRBs as one resource unit. As illustrated in FIG. 4, as an example, two PRBs could be used as one resource unit, in which resources (REs) in the resource unit (2 PRBs) are divided into 3 groups, and each group has 8 REs as comparing with 4 REs when a resource unit is one PRB. By doing this, the longer orthogonal or quasi-orthogonal sequences could be used, which firstly may improve channel estimation performance, and secondly may allow multiplexing more short PUCCHs in each unit (now 8 as comparing with 4 when a resource unit is one PRB) . Certainly, comparing with the FDM manner, the total PUCCH multiplexing capacity is the same. Using a longer resource unit may also bring more stable interference as compared with using a shorter resource unit.

As illustrated in FIG. 5, the grouping of resources on short PUCCH with 1 symbol could be extended to short PUCCH with 2 symbols. FIG. 5 illustrates such an example, where the same way of resources grouping could be applied to both symbols, assuming symbol N is the last symbol of the slot, while symbol N-1 is the second last symbol in the slot. Such groups of resources could be used to carry RS or UCI. For example,

groups

1 and 4 could be used to carry RS, while other groups could be used to carry UCI. Groups in different symbols could be used to carry the same types of signals or alternatively different types of signals. For example, if CDM is also used along time direction for increasing short PUCCH capacity, the same types of signals could be carried by the corresponding groups on each symbol aligned in time. To be more specific, for example,

groups

1 and 4 could be used to carry RS, while

groups

2 and 5 could be used to carry the same set of UCI, while

groups

3 and 6 could be used to carry another set of UCI. In this case, OCC (orthogonal cover code) could be further applied to each pair of REs on two symbols aligned in time, as illustrated in FIG. 5. That will allow the multiplexing of more short PUCCHs and double the short PUCCH capacity on one PRB with 2 symbols. If CDM is not applied in time direction, then each group on each symbol could be used to carry different UCIs. For example, group 1 on symbol N-1 could be used to carry RS, while

groups

2, 3, 4, 5, 6 could be used to carry different sets of UCIs of the same UE. Furthermore, in each group, multiple short-PUCCHs from different UEs could be multiplexed in the CDM manner. Similar mechanism/extension could be used to construct short PUCCH structure on multiple symbols.

As illustrated in FIG. 6, The resources for 2-symbol short PUCCH could be grouped together directly instead of using the extension of grouping from 1-symbol short PUCCH. FIG. 6 illustrates an example where the REs in 2 symbols are grouped together in both time and frequency instead of grouping along frequency direction on each symbol. Each group could be assigned to transmit RS or UCI. For example, group 1 could be used to transmit RS while

groups

2 and 3 could be used to transmit modulated/spread UCI. The same content (for both RS and UCI) could be transmitted on a pair of REs aligned in time on different symbols and OCC could be applied on each pair of RE in time to increase the short PUCCH capacity.

As illustrated in FIGs. 7 and 8, one design aspect for short PUCCH is to have frequency diversity gain. This is especially critical considering the number of symbols that could be used to carry short PUCCH is small. To achieve that, frequency hopping could be used where the same units/groups that carry the same sets of UCI of a UE could be transmitted apart on frequency. FIG. 7 illustrates an example that the frequency hopping is completed on the same symbol while FIG. 8 illustrates an example how it is done across 2 symbols. The latter case would also allow the power boosting as two hopping occasions are transmitted on two different symbols.

In addition to frequency diversity, other types of diversity could be exploited as well to improve the coverage for short PUCCH. One of such diversity is transmit diversity. As mentioned earlier, using different sequences for signals from different transmit antenna ports could be one way to achieve that. Alternatively, other kind of transmit diversity could be considered. As CDM could be used along frequency to multiplex short PUCCHs from different UEs, SFBC scheme may not be suitable as that scheme will break the sequence order and therefore the orthogonality. One technique that could be considered is FSTD (frequency switch transmit diversity) scheme. FIG. 9 illustrates an example, in which group 1 can be used for RS transmission and RS from each transmit antenna could use different orthogonal sequences.

Groups

2 and 3 are used to transmit the same set of UCI from each antenna port. When group 2 is transmitted from antenna port #1, the REs corresponding to group 3 are nulled on that antenna port (and thus to avoid interference to that transmitted from antenna port #2) , while when group 3 is transmitted from antenna port #2, the REs corresponding to group 2 are nulled on that antenna port. An RE in each group is paired with an RE in another group on which the same modulated/spread symbols (e.g., S1, S2, S3 and S4 as illustrated in FIG. 9) are transmitted from each antenna port respectively. This scheme could be applied to both 1-symbol and 2-symbol short PUCCHs.

For a 2-symbol short PUCCH, another transmit diversity that could be considered is the space time block code (STBC) scheme. FIG. 10 illustrates an example. The

groups

1 and 4 are still used for RS and CDM (e.g., using OCC in time) , and can be used to create orthogonal RS from each antenna port. Modulated and spread symbols transmitted on each pair of RE in

groups

2 and 5 aligned in time are STBC coded and transmitted from each antenna port. So do those transmitted on corresponding pair of REs in

groups

3 and 6. By applying the STBC scheme, the spread sequences along frequency in each group maintain orthogonality, and therefore, multiple short PUCCHs could still be multiplexed using different orthogonal sequences. As STBC scheme creates two orthogonal streams from each antenna port, inter-stream interference can be avoided and thus it can achieve optimal transmit diversity gain comparing with other transmit diversity schemes. In addition, this scheme does not require additional resources (sequences) to achieve transmit diversity and thus maintain the same short PUCCH capacity as single antenna port, and a simple decoder at gNB could be used to decode the STBC.

That is, the configurations on resource units and groups (may include the size of resource units and groups, number of groups in each unit, and etc. ) could be signaled to the UE on a semi-static basis. Some groups could be used for RS transmission and others could be used for UCI, and such assignments could be either semi-statically configured or dynamically indicated. Different units and groups could be used to transmit the same or different UCIs. If the payload of UCI increases, more units/groups could be allocated to carry different UCIs. To improve the short PUCCH capacity, more PRBs or longer units with more PRBs could be allocated. In general, such resource partition and allocation provides flexible ways of supporting different design aspects of short PUCCH including scalability, RS overhead, channel estimation, interference, diversity.
